Could you run a checksum of some sort on the result and store that locally? Then when your application queries the database, you can compare its checksum and determine if you should import it?

It looks like you may be able to use the ORA_HASH function to accomplish this.

Update: Another good resource: 10g’s ORA_HASH function to determine if two Oracle tables’ data are equal

Here on a openSuse 12.3 the solution was installing the 32-bit version of libaio in addition. Oracle seems to need this now, although on 12.1 it run without the 32-bit version.

I think that more accurate is this syntax:

SELECT CONVERT(CHAR(10), GETDATE(), 103)

I add SELECT and GETDATE() for instant testing purposes :)

:g/^M/s// /g

If you type ^M using Shift+6 Caps+M it won't accept.

You need to type ctrl+v ctrl+m.

There are several ways to do it This is the better way

res.download('/report-12345.pdf')

or in your case this might be

app.get('/download', function(req, res){
  const file = `${__dirname}/upload-folder/dramaticpenguin.MOV`;
  res.download(file); // Set disposition and send it.
});

What I have done in this case is pass an array, where the key is the parameter name, and the value is the value.

$optional = array(
  "param" => $param1,
  "param2" => $param2
);

function func($required, $requiredTwo, $optional) {
  if(isset($optional["param2"])) {
    doWork();
  }
}

Assuming doc is your instance of org.w3c.dom.Document:

TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
StringWriter writer = new StringWriter();
transformer.transform(new DOMSource(doc), new StreamResult(writer));
String output = writer.getBuffer().toString().replaceAll("\n|\r", "");

in intelliJ IDEA go-lang plugin (and i assume in jetbrains Gogland) you can just set the test kind to file under run > edit configurations

You can always call funciton differently: foo.call(this); in this way you will be able to use this context inside the function.

Example:

<button onclick="foo.call(this)" id="bar">Button</button>?

var foo = function()
{
    this.innerHTML = "Not a button";
};

I know this post is old. But if anyone is looking for more flexible solution, here it is

var options = {

            yAxes: [{
                ticks: {
                    beginAtZero: true,
                    callback: function(label, index, labels) {
                        return Intl.NumberFormat().format(label);
                        // 1,350

                        return Intl.NumberFormat('hi', { 
                            style: 'currency', currency: 'INR', minimumFractionDigits: 0, 
                        }).format(label).replace(/^(\D+)/, '$1 ');
                        // ? 1,350

                        // return Intl.NumberFormat('hi', {
                            style: 'currency', currency: 'INR', currencyDisplay: 'symbol', minimumFractionDigits: 2 
                        }).format(label).replace(/^(\D+)/, '$1 ');
                        // ? 1,350.00
                    }
                }

You need to run:

npx tsc

...rather than just calling tsc own its on like a Windows command as everyone else seems to be suggesting.

If you don't have npx installed then you should. It should be installed globally (unlike Typescript). So first run:

npm install -g npx

..then run npx tsc.

to add a little more to the answer from b_levitt... on global.asax:

Try withColumn with the function when as follows:

val sqlContext = new SQLContext(sc)
import sqlContext.implicits._ // for `toDF` and $""
import org.apache.spark.sql.functions._ // for `when`

val df = sc.parallelize(Seq((4, "blah", 2), (2, "", 3), (56, "foo", 3), (100, null, 5)))
    .toDF("A", "B", "C")

val newDf = df.withColumn("D", when($"B".isNull or $"B" === "", 0).otherwise(1))

newDf.show() shows

+---+----+---+---+
|  A|   B|  C|  D|
+---+----+---+---+
|  4|blah|  2|  1|
|  2|    |  3|  0|
| 56| foo|  3|  1|
|100|null|  5|  0|
+---+----+---+---+

I added the (100, null, 5) row for testing the isNull case.

I tried this code with Spark 1.6.0 but as commented in the code of when, it works on the versions after 1.4.0.

The asterisk (*) means "zero or more of the previous item".

If you want to match any single character use

sed -i 's/string-./string-0/g' file.txt

If you want to match any string (i.e. any single character zero or more times) use

sed -i 's/string-.*/string-0/g' file.txt

Yes, a table have one or many foreign keys and each foreign keys hava a different parent table.

After building a few applications, some in Symfony-PHP, some .NET MVC, some ROR, i've found that the best way for me is to use Yeoman.io with the AngularJS generator.

That's the most popular and common structure and best maintained.

And most importantly, by keeping that structure, it helps you separate your client side code and to make it agnostic to the server-side technology (all kinds of different folder structures and different server-side templating engines).

That way you can easily duplicate and reuse yours and others code.

Here it is before grunt build: (but use the yeoman generator, don't just create it!)

/app
    /scripts
            /controllers
            /directives
            /services
            /filters
            app.js
    /views
    /styles
    /img
    /bower_components
    index.html
bower.json

And after grunt build (concat, uglify, rev, etc...):

    /scripts
        scripts.min.js (all JS concatenated, minified and grunt-rev)
        vendor.min.js  (all bower components concatenated, minified and grunt-rev)
    /views
    /styles
        mergedAndMinified.css  (grunt-cssmin)
    /images
    index.html  (grunt-htmlmin)

if you want to set the home or back icon (not logo or static icon) so you can use

 getSupportActionBar().setDisplayHomeAsUpEnabled(true);
 getSupportActionBar().setHomeAsUpIndicator( getResources().getDrawable(R.drawable.home) );

For Java 12 onwards, official General-Availability (GA) and Early-Access (EA) Windows 64-bit builds of the OpenJDK (GPL2 + Classpath Exception) from Oracle are available as tar.gz/zip from the JDK website.

If you prefer an installer, there are several distributions. There is a public Google Doc and Blog post by the Java Champions community which lists the best-supported OpenJDK distributions. Currently, these are:

• AdoptOpenJDK, which also has a version with OpenJ9 instead of Hotspot as its VM (backed by IBM and jClarity)
• Amazon Corretto
• Liberica from Bellsoft
• Red Hat OpenJDK
• SAPMachine (backed by SAP)
• Zulu Community (backed by Azul Systems)

edit: I missed the part about checking if the directories exist at first, so I added that in, completing the script. Also, have addressed issues raised in comments; fixed the regular expression, switched from == to eq.

This should be a portable, POSIX compliant script as far as I can tell; it doesn't use any bashisms, which is actually important because /bin/sh on Ubuntu is actually dash these days, not bash.

Assign after the EXEC token:

DECLARE @returnValue INT

EXEC @returnValue = SP_One

NOTE: This is mentioned in the question but restarting Visual Studio fixes the issue in most cases.

Updating Visual Studio to 'Update 2' got it working again.

Tools -> Extensions and Updates ->Visual Studio Update 2

As mentioned in the question and the link i posted therein, I'd already updated NuGet Package Manager to 3.4.4 prior to this and restarted to no avail, so I don't know if the combination of both these actions worked.

Just for fun, here is a way using a function:

 jsonObject = (new Function('return ' + jsonFormatData))()

The colon is a built-in command that does nothing, but returns 0 (success). Thus, it's shorter (and faster) than calling an actual command to do the same thing.

This is untested, but I believe the syntax should work for a lambda query. As you join more tables with this syntax you have to drill further down into the new objects to reach the values you want to manipulate.

var fullEntries = dbContext.tbl_EntryPoint
    .Join(
        dbContext.tbl_Entry,
        entryPoint => entryPoint.EID,
        entry => entry.EID,
        (entryPoint, entry) => new { entryPoint, entry }
    )
    .Join(
        dbContext.tbl_Title,
        combinedEntry => combinedEntry.entry.TID,
        title => title.TID,
        (combinedEntry, title) => new 
        {
            UID = combinedEntry.entry.OwnerUID,
            TID = combinedEntry.entry.TID,
            EID = combinedEntry.entryPoint.EID,
            Title = title.Title
        }
    )
    .Where(fullEntry => fullEntry.UID == user.UID)
    .Take(10);

the best way to give a hint is placeholder like this:

<input.... placeholder="hint".../>

Use the ViewTreeObserver on the View to wait for the first layout. Only after the first layout will getWidth()/getHeight()/getMeasuredWidth()/getMeasuredHeight() work.

ViewTreeObserver viewTreeObserver = view.getViewTreeObserver();
if (viewTreeObserver.isAlive()) {
  viewTreeObserver.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
    @Override
    public void onGlobalLayout() {
      view.getViewTreeObserver().removeOnGlobalLayoutListener(this);
      viewWidth = view.getWidth();
      viewHeight = view.getHeight();
    }
  });
}

For me, the simplest way to use ALIAS in WHERE class is to create a subquery and select from it instead.

Example:

WITH Q1 AS (
    SELECT LENGTH(name) AS name_length,
    id,
    name
    FROM any_table
)

SELECT id, name, name_length form Q1 where name_length > 0

Cheers, Kel

This works very well for me. Go to the android-support-v7-appcompat project and open the file "project.properties" and insert this lines if missing:

target=android-25_x000D_
compile=android-21

Create an empty list of Character and then make a loop to get every character from the array and put them in the list one by one.

List<Character> characterList = new ArrayList<Character>();
char arrayChar[] = abc.toCharArray();
for (char aChar : arrayChar) 
{
    characterList.add(aChar); //  autoboxing 
}

One-liner in java 8 syntax:

pdfTestDir.listFiles((dir, name) -> name.toLowerCase().endsWith(".txt"));

I wound up writing my own command-line tool to take care of this. It's similar to cut, except it knows what to do with quoted fields, etc. This tool, paired with @Jimothy's answer, allows me to get a headerless CSV from a remote MySQL server I have no filesystem access to onto my local machine with this command:

$ mysql -N -e "select people, places from things" | csvm -i '\t' -o ','
Bill,"Raleigh, NC"

//Try this if you can't use -std=c++11:-
int number=55;
char tempStr[32] = {0};
sprintf(tempStr, "%d", number);

Full version:

<? echo date('F Y'); ?>

Short version:

<? echo date('M Y'); ?>

Here is a good reference for the different date options.

update

To show the previous month we would have to introduce the mktime() function and make use of the optional timestamp parameter for the date() function. Like this:

echo date('F Y', mktime(0, 0, 0, date('m')-1, 1, date('Y')));

This will also work (it's typically used to get the last day of the previous month):

echo date('F Y', mktime(0, 0, 0, date('m'), 0, date('Y')));

Hope that helps.

Make sure you include the = sign in addition to passing the arguments to the function. I.E.

=SUM(A1:A3) //this would give you the sum of cells A1, A2, and A3.

You should follow the guidelines on Add a secondary horizontal axis:

Add a secondary horizontal axis

To complete this procedure, you must have a chart that displays a secondary vertical axis. To add a secondary vertical axis, see Add a secondary vertical axis.

1. Click a chart that displays a secondary vertical axis. This displays the Chart Tools, adding the Design, Layout, and Format tabs.

2. On the Layout tab, in the Axes group, click Axes.

   

3. Click Secondary Horizontal Axis, and then click the display option that you want.

Add a secondary vertical axis

You can plot data on a secondary vertical axis one data series at a time. To plot more than one data series on the secondary vertical axis, repeat this procedure for each data series that you want to display on the secondary vertical axis.

1. In a chart, click the data series that you want to plot on a secondary vertical axis, or do the following to select the data series from a list of chart elements:

   • Click the chart.

     This displays the Chart Tools, adding the Design, Layout, and Format tabs.

   • On the Format tab, in the Current Selection group, click the arrow in the Chart Elements box, and then click the data series that you want to plot along a secondary vertical axis.

     

2. On the Format tab, in the Current Selection group, click Format Selection. The Format Data Series dialog box is displayed.

   Note: If a different dialog box is displayed, repeat step 1 and make sure that you select a data series in the chart.

3. On the Series Options tab, under Plot Series On, click Secondary Axis and then click Close.

   A secondary vertical axis is displayed in the chart.

4. To change the display of the secondary vertical axis, do the following:

   • On the Layout tab, in the Axes group, click Axes.

   • Click Secondary Vertical Axis, and then click the display option that you want.

5. To change the axis options of the secondary vertical axis, do the following:

   • Right-click the secondary vertical axis, and then click Format Axis.

   • Under Axis Options, select the options that you want to use.

You can use splash screen in your first loading Activity like this:

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

        Thread welcomeThread = new Thread() {

            @Override
            public void run() {
                try {
                    super.run();
                    sleep(10000);  //Delay of 10 seconds
                } catch (Exception e) {

                } finally {

                    Intent i = new Intent(SplashActivity.this,
                            MainActivity.class);
                    startActivity(i);
                    finish();
                }
            }
        };
        welcomeThread.start();
    }

Hope this code helps you.

Three types of regret

A lot of the existing answers don't seem to answer the actual question. They are about what the commands do, not about what you (the user) want — the use case. But that is what the OP asked about!

It might be more helpful to couch the description in terms of what it is precisely that you regret at the time you give a git reset command. Let's say we have this:

A - B - C - D <- HEAD

Here are some possible regrets and what to do about them:

1. I regret that B, C, and D are not one commit.

git reset --soft A. I can now immediately commit and presto, all the changes since A are one commit.

2. I regret that B, C, and D are not ten commits.

git reset --mixed A. The commits are gone and the index is back at A, but the work area still looks as it did after D. So now I can add-and-commit in a whole different grouping.

3. I regret that B, C, and D happened on this branch; I wish I had branched after A and they had happened on that other branch.

Make a new branch otherbranch, and then git reset --hard A. The current branch now ends at A, with otherbranch stemming from it.

(Of course you could also use a hard reset because you wish B, C, and D had never happened at all.)

As far as i know this seems out of scope of an IDE. Copyin ,you can copy the string and then try to format it using ctrl+shift+ F Most often these multiline strings are not used hard coded,rather they shall be used from property or xml files.which can be edited at later point of time without the need for code change

For example, your remote host is example.com and remote login name is user1:

scp [email protected]:/path/to/file /path/to/store/file

webRequest.ContentType = "application/x-www-form-urlencoded";

1. Where does application/x-www-form-urlencoded's name come from?

   If you send HTTP GET request, you can use query parameters as follows:

   http://example.com/path/to/page?name=ferret&color=purple

   The content of the fields is encoded as a query string. The application/x-www-form- urlencoded's name come from the previous url query parameter but the query parameters is in where the body of request instead of url.

   The whole form data is sent as a long query string.The query string contains name- value pairs separated by & character

   e.g. field1=value1&field2=value2

2. It can be simple request called simple - don't trigger a preflight check

   Simple request must have some properties. You can look here for more info. One of them is that there are only three values allowed for Content-Type header for simple requests

   • application/x-www-form-urlencoded
   • multipart/form-data
   • text/plain

3.For mostly flat param trees, application/x-www-form-urlencoded is tried and tested.

request.ContentType = "application/json; charset=utf-8";

1. The data will be json format.

axios and superagent, two of the more popular npm HTTP libraries, work with JSON bodies by default.

{
  "id": 1,
  "name": "Foo",
  "price": 123,
  "tags": [
    "Bar",
    "Eek"
  ],
  "stock": {
    "warehouse": 300,
    "retail": 20
  }
}

2. "application/json" Content-Type is one of the Preflighted requests.

Now, if the request isn't simple request, the browser automatically sends a HTTP request before the original one by OPTIONS method to check whether it is safe to send the original request. If itis ok, Then send actual request. You can look here for more info.

3. application/json is beginner-friendly. URL encoded arrays can be a nightmare!

Basically, fs.readFileSync throws an error when a file is not found. This error is from the Error prototype and thrown using throw, hence the only way to catch is with a try / catch block:

var fileContents;
try {
  fileContents = fs.readFileSync('foo.bar');
} catch (err) {
  // Here you get the error when the file was not found,
  // but you also get any other error
}

Unfortunately you can not detect which error has been thrown just by looking at its prototype chain:

if (err instanceof Error)

is the best you can do, and this will be true for most (if not all) errors. Hence I'd suggest you go with the code property and check its value:

if (err.code === 'ENOENT') {
  console.log('File not found!');
} else {
  throw err;
}

This way, you deal only with this specific error and re-throw all other errors.

Alternatively, you can also access the error's message property to verify the detailed error message, which in this case is:

ENOENT, no such file or directory 'foo.bar'

Hope this helps.

The compiler needs to know the size of the second dimension in your two dimensional array. For example:

void print_graph(g_node graph_node[], double weight[][5], int nodes);

C#

public static void TakeScreenshot(IWebDriver driver, String filename)
{
    // Take a screenshot and save it to filename
    Screenshot screenshot = ((ITakesScreenshot)driver).GetScreenshot();
    screenshot.SaveAsFile(filename, ImageFormat.Png);
}

    private void TestBench()
    {
        // An object to test
        string[] stringEnumerable = new string[] { "Easy", "as", "Pi" };

        ObjectListFromUnknown(stringEnumerable);
    }

    private void ObjectListFromUnknown(object o)
    {
        if (typeof(IEnumerable<object>).IsAssignableFrom(o.GetType()))
        {
            List<object> listO = ((IEnumerable<object>)o).ToList();
            // Test it
            foreach (var v in listO)

                Console.WriteLine(v);
            }
        }
    }

In your Jest configuration, add setupFilesAfterEnv: ["./setupTests.js"], create that file, and add the code you want to run before the tests:

// setupTests.js
window.crypto = {

#can not find 5!

From the docs: break and continue Statements, and else Clauses on Loops

Loop statements may have an else clause; it is executed when the loop terminates through exhaustion of the list (with for) or when the condition becomes false (with while), but not when the loop is terminated by a break statement. This is exemplified by the following loop, which searches for prime numbers:

>>> for n in range(2, 10):
...     for x in range(2, n):
...         if n % x == 0:
...             print(n, 'equals', x, '*', n//x)
...             break
...     else:
...         # loop fell through without finding a factor
...         print(n, 'is a prime number')
...
2 is a prime number
3 is a prime number
4 equals 2 * 2
5 is a prime number
6 equals 2 * 3
7 is a prime number
8 equals 2 * 4
9 equals 3 * 3

(Yes, this is the correct code. Look closely: the else clause belongs to the for loop, not the if statement.)

When used with a loop, the else clause has more in common with the else clause of a try statement than it does that of if statements: a try statement’s else clause runs when no exception occurs, and a loop’s else clause runs when no break occurs. For more on the try statement and exceptions, see Handling Exceptions.

The continue statement, also borrowed from C, continues with the next iteration of the loop:

>>> for num in range(2, 10):
...     if num % 2 == 0:
...         print("Found an even number", num)
...         continue
...     print("Found a number", num)
Found an even number 2
Found a number 3
Found an even number 4
Found a number 5
Found an even number 6
Found a number 7
Found an even number 8
Found a number 9

Python doesn't have a feature to access the function or its name within the function itself. It has been proposed but rejected. If you don't want to play with the stack yourself, you should either use "bar" or bar.__name__ depending on context.

The given rejection notice is:

This PEP is rejected. It is not clear how it should be implemented or what the precise semantics should be in edge cases, and there aren't enough important use cases given. response has been lukewarm at best.

How about using the replaceAll() method?

I know this question has been answered already but for those that have tried them all and you are still getting the annoying "Permission denied (publickey)". Try running your command with SUDO. Of course this is a temporary solution and you should set permissions correctly but at least that will let you identify that your current user is not running with the privileges you need (as you assumed)

sudo ssh -i amazonec2.pem ec2-xxx-xxx-xxx-xxx.us-west-2.compute.amazonaws.com

Once you do this you'll get a message like this:

Please login as the user "ec2-user" rather than the user "root"

Which is also sparsely documented. In that case just do this:

sudo ssh -i amazonec2.pem ec2-xxx-xxx-xxx-xxx.us-west-2.compute.amazonaws.com -l ec2-user

And you'll get the glorious:

   __|  __|_  )
   _|  (     /   Amazon Linux AMI
  ___|\___|___|

I had the same problem. I solved it by performing a clean and then building the project from Android Studio 3.0 menu:

1. build -> clean project
2. build-> rebuild project

actually, i think the best solution is described on this link:

http://blog.synyx.de/2011/11/android-listview-with-rounded-corners/

in short, it uses a different background for the top, middle and bottom items, so that the top and bottom ones would be rounded.

Android supports the dd command.

dd if=/path/file of=/path/file

Well it simply means loading data you need currently instead of loading whole bunch of data at once which you won't use now. Thereby making application load time faster than usual.

Like this:

String[][] arrays = { array1, array2, array3, array4, array5 };

or

String[][] arrays = new String[][] { array1, array2, array3, array4, array5 };

(The latter syntax can be used in assignments other than at the point of the variable declaration, whereas the shorter syntax only works with declarations.)

Basically boolean represent a primitive data type where Boolean represent a reference data type. this story is started when Java want to become purely object oriented it's provided wrapper class concept to over come to use of primitive data type.

boolean b1;
Boolean b2;

b1 and b2 are not same.

Assuming you're talking about a static library, DUMPBIN /SYMBOLS shows the functions and data objects in the library. If you're talking about an import library (a .lib used to refer to symbols exported from a DLL), then you want DUMPBIN /EXPORTS.

Note that for functions linked with the "C" binary interface, this still won't get you return values, parameters, or calling convention. That information isn't encoded in the .lib at all; you have to know that ahead of time (via prototypes in header files, for example) in order to call them correctly.

For functions linked with the C++ binary interface, the calling convention and arguments are encoded in the exported name of the function (also called "name mangling"). DUMPBIN /SYMBOLS will show you both the "mangled" function name as well as the decoded set of parameters.

Export:

mysqldump -u root -p --all-databases > alldb.sql

Look up the documentation for mysqldump. You may want to use some of the options mentioned in comments:

mysqldump -u root -p --opt --all-databases > alldb.sql
mysqldump -u root -p --all-databases --skip-lock-tables > alldb.sql

Import:

mysql -u root -p < alldb.sql

In C++ you are supposed to declare functions before you can use them. In your code integrate is not declared before the point of the first call to integrate. The same applies to sum. Hence the error. Either reorder your definitions so that function definition precedes the first call to that function, or introduce a [forward] non-defining declaration for each function.

Additionally, defining external non-inline functions in header files in a no-no in C++. Your definitions of SkewNormalEvalutatable::SkewNormalEvalutatable, getSkewNormal, integrate etc. have no business being in header file.

Also SkewNormalEvalutatable e(); declaration in C++ declares a function e, not an object e as you seem to assume. The simple SkewNormalEvalutatable e; will declare an object initialized by default constructor.

Also, you receive the last parameter of integrate (and of sum) by value as an object of Evaluatable type. That means that attempting to pass SkewNormalEvalutatable as last argument of integrate will result in SkewNormalEvalutatable getting sliced to Evaluatable. Polymorphism won't work because of that. If you want polymorphic behavior, you have to receive this parameter by reference or by pointer, but not by value.

When you use Mongoose to store dates into MongoDB you need to use toISOString() because all dates are stored as ISOdates with miliseconds.

moment.format()

Tomcat-7 JNDI configuration:

Steps:

1. Open the server.xml in the tomcat-dir/conf
2. Add below <Resource> tag with your DB details inside <GlobalNamingResources>

<Resource name="jdbc/mydb"
          global="jdbc/mydb"
          auth="Container"
          type="javax.sql.DataSource"
          driverClassName="com.mysql.jdbc.Driver"
          url="jdbc:mysql://localhost:3306/test"
          username="root"
          password=""
          maxActive="10"
          maxIdle="10"
          minIdle="5"
          maxWait="10000"/>

3. Save the server.xml file
4. Open the context.xml in the tomcat-dir/conf
5. Add the below <ResourceLink> inside the <Context> tag.

<ResourceLink name="jdbc/mydb" 
              global="jdbc/mydb"
              auth="Container"
              type="javax.sql.DataSource" />

6. Save the context.xml
7. Open the hibernate-cfg.xml file and add and remove below properties.

Adding:
-------
<property name="connection.datasource">java:comp/env/jdbc/mydb</property>

Removing:
--------
<!--<property name="connection.url">jdbc:mysql://localhost:3306/mydb</property> -->
<!--<property name="connection.username">root</property> -->
<!--<property name="connection.password"></property> -->

8. Save the file and put latest .WAR file in tomcat.
9. Restart the tomcat. the DB connection will work.

new BigInteger(1, myString.getBytes(/*YOUR_CHARSET?*/)).toString(16)

if not exists (select dist_id from tbl_stock where dist_id= @cust_id and item_id=@item_id)
    insert into tbl_stock(dist_id,item_id,qty)values(@cust_id, @item_id, @qty); 
else
    update tbl_stock set qty=(qty + @qty) where dist_id= @cust_id and item_id= @item_id;

You shouldn't use ${varName} when you're outside of strings, you should just use varName. Inside strings you use it like this; echo "this is a string ${someVariable}";. Infact you can place an general java expression inside of ${...}; echo "this is a string ${func(arg1, arg2)}.

sql-surfer and MikroDel,

actually, the answer is not that complicated! You just need to add:

export JAVA_HOME=(/usr/libexec/java_home)

to your shell profile/configuration file. The only question is - which shell are you using? If you're using for example FISH, then adding that line to .profile or .bash_profile will not work at all. Adding it to config.fish file though will do the trick. Permanently.

You can try the country restriction

function initialize() {

 var options = {
  types: ['(cities)'],
  componentRestrictions: {country: "us"}
 };

 var input = document.getElementById('searchTextField');
 var autocomplete = new google.maps.places.Autocomplete(input, options);
}

More info:

ISO 3166-1 alpha-2 can be used to restrict results to specific groups. Currently, you can use componentRestrictions to filter by country.

The country must be passed as as a two character, ISO 3166-1 Alpha-2 compatible country code.

It is illegal to nest EL expressions: you should inline them. Using JSTL is perfectly valid in your situation. Correcting the mistake, you'll make the code working:

<html xmlns="http://www.w3.org/1999/xhtml" xmlns:c="http://java.sun.com/jstl/core">
    <c:if test="#{not empty user or user.userId eq 0}">
        <a href="Images/thumb_02.jpg" target="_blank" ></a>
        <img src="Images/thumb_02.jpg" />
    </c:if>
    <c:if test="#{empty user or user.userId eq 0}">
        <a href="/DisplayBlobExample?userId=#{user.userId}" target="_blank"></a>
        <img src="/DisplayBlobExample?userId=#{user.userId}" />
    </c:if>
</html>

Another solution is to specify all the conditions you want inside an EL of one element. Though it could be heavier and less readable, here it is:

<a href="#{not empty user or user.userId eq 0 ? '/Images/thumb_02.jpg' : '/DisplayBlobExample?userId='}#{not empty user or user.userId eq 0 ? '' : user.userId}" target="_blank"></a>
<img src="#{not empty user or user.userId eq 0 ? '/Images/thumb_02.jpg' : '/DisplayBlobExample?userId='}#{not empty user or user.userId eq 0 ? '' : user.userId}" target="_blank"></img>

cmd

Tunnel all your internet traffic through a socks proxy:

netsh winhttp set proxy proxy-server="socks=localhost:9090" bypass-list="localhost"

View the current proxy settings:

netsh winhttp show proxy

Clear all proxy settings:

netsh winhttp reset proxy

This solution:

1. has timeout
2. polling works also after error response

Minimum version of jQuery is 1.12

$(document).ready(function () {
  function poll () {
    $.get({
      url: '/api/stream/',
      success: function (data) {
        console.log(data)
      },
      timeout: 10000                    // == 10 seconds timeout
    }).always(function () {
      setTimeout(poll, 30000)           // == 30 seconds polling period
    })
  }

  // start polling
  poll()
})

Try to use anyMatch of Lambda Expression. It is much better approach.

 boolean idExists = tabPane.getTabs().stream()
            .anyMatch(t -> t.getId().equals(idToCheck));

controller class is not working any functions.

so I recommend to you use the following scripts

global $argv;

if(is_array($argv)){
    $action = $argv[1];
    $method = $argv[2];
}else{
    $request_uri = $_SERVER['REQUEST_URI'];
    $pattern = "/.*?\/index\.php\/(.*?)\/(.*?)$/";
    preg_match($pattern, $request_uri, $params);
    $action = $params[1];
    $method = $params[2];
}

If you want to make sure that every implementation of the interface contains specific field, you simply need to add to your interface the getter for that field:

interface IMyMessage(){
    @NonNull String getReceiver();
}

• it won't break encapsulation
• it will let know to everyone who use your interface that the Receiver object has to be passed to the class in some way (either by constructor or by setter)

On most Linux distributions, you can use pidof(8).

It will print the process ids of all running instances of specified processes, or nothing if there are no instances running.

For instance, on my system (I have four instances of bashand one instance of remmina running):

$ pidof bash remmina
6148 6147 6144 5603 21598

On other Unices, pgrep or a combination of ps and grep will achieve the same thing, as others have rightfully pointed out.

i Solve My Problem Through this Method

<script>
var someSession = '<%= Session["SessionName"].ToString() %>';
alert(someSession)
</script>

This code you can write in Aspx. If you want this in some js.file, you have two ways:

1. Make aspx file which writes complete JS code, and set source of this file as Script src
2. Make handler, to process JS file as aspx.

It's amazing what the Framework already does for us.

List<int> myValues;
string csv = String.Join(",", myValues.Select(x => x.ToString()).ToArray());

For the general case:

IEnumerable<T> myList;
string csv = String.Join(",", myList.Select(x => x.ToString()).ToArray());

As you can see, it's effectively no different. Beware that you might need to actually wrap x.ToString() in quotes (i.e., "\"" + x.ToString() + "\"") in case x.ToString() contains commas.

For an interesting read on a slight variant of this: see Comma Quibbling on Eric Lippert's blog.

Note: This was written before .NET 4.0 was officially released. Now we can just say

IEnumerable<T> sequence;
string csv = String.Join(",", sequence);

using the overload String.Join<T>(string, IEnumerable<T>). This method will automatically project each element x to x.ToString().

When using percentage, the height it relative to the width and will dynamically change along with it:

chart: {
    height: (9 / 16 * 100) + '%' // 16:9 ratio
},

JSFiddle Highcharts with percentage height

This will do what you want:

select * 
  from orders_products 
       INNER JOIN orders 
          ON orders_products.orders_id = orders.orders_id
 where products_id in (180, 181);

You can also do this without VBA from the find/replace dialogue box. My answer was at https://stackoverflow.com/a/6116681/509840 .

Use like below:

  yourFunc(input: any):Observable<string> {
var requestHeader = { headers: new HttpHeaders({ 'Content-Type': 'text/plain', 'No-Auth': 'False' })};
const headers = new HttpHeaders().set('Content-Type', 'text/plain; charset=utf-8');
return this.http.post<string>(this.yourBaseApi+ '/do-api', input, { headers, responseType: 'text' as 'json'  });

}

Set your SMTP auth to true if using the PHPmailer class:

$mail->SMTPAuth = true;

Knockout.js validation is handy but it is not robust. You always have to create server side validation replica. In your case (as you use knockout.js) you are sending JSON data to server and back asynchronously, so you can make user think that he sees client side validation, but in fact it would be asynchronous server side validation.

Take a look at example here upida.cloudapp.net:8080/org.upida.example.knockout/order/create?clientId=1 This is a "Create Order" link. Try to click "save", and play with products. This example is done using upida library (there are spring mvc version and asp.net mvc of this library) from codeplex.

If you could reload this, you might be able to use dtypes argument.

pd.read_csv(..., dtype={'COL_NAME':'str'})

Check out the pack URI syntax. You want something like this:

<ResourceDictionary Source="pack://application:,,,/YourAssembly;component/Subfolder/YourResourceFile.xaml"/>

var month = mydate.getMonth(); // month (in integer 0-11)
var year = mydate.getFullYear(); // year

Then all you would need to have is an array of months:

var months = ['Jan', 'Feb', 'Mar', ...];

And then to show it:

alert(months[month] + "  " + year);

Try this, It's worked:

@php 
   echo $text; 
@endphp

I hide the warnings in the pink boxes by running the following code in a cell:

from IPython.display import HTML
HTML('''<script>
code_show_err=false; 
function code_toggle_err() {
 if (code_show_err){
 $('div.output_stderr').hide();
 } else {
 $('div.output_stderr').show();
 }
 code_show_err = !code_show_err
} 
$( document ).ready(code_toggle_err);
</script>
To toggle on/off output_stderr, click <a href="javascript:code_toggle_err()">here</a>.''')

Consider the option of encapsulating this particular dictionary and provide a method to return the value for that key:

public static class NumbersAdapter
{
    private static readonly Dictionary<string, string> Mapping = new Dictionary<string, string>
    {
        ["1"] = "One",
        ["2"] = "Two",
        ["3"] = "Three"
    };

    public static string GetValue(string key)
    {
        return Mapping.ContainsKey(key) ? Mapping[key] : key;
    }
}

Then you can manage the behaviour of this dictionary.

For example here: if the dictionary doesn't have the key, it returns key that you pass by parameter.

SOLUTION for WORDPRESS PLUGINS:

I think, get_option() returns FALSE (instead of EMPTY). So, check your plugin. Instead of:

if (empty(get_option('smth')))

there should be:

if (!get_option('smth'))

DEVELOPER runs autoconf and automake:

1. autoconf -- creates shippable configure script
   (which the installer will later run to make the Makefile)

• ‘autoconf’ is a macro processor.
• It converts configure.ac, which is a shell script using macro instructions, into configure, a full-fledged shell script.

2. automake - creates shippable Makefile.in data file
   (which configure will later read to make the Makefile)

• Automake helps with creating portable and GNU-standard compliant Makefiles.
• ‘automake’ creates complex Makefile.ins from simple Makefile.ams

INSTALLER runs configure, make and sudo make install:

./configure       # Creates  Makefile        (from     Makefile.in).  
make              # Creates  the application (from the Makefile just created).  

sudo make install # Installs the application 
                  #   Often, by default its files are installed into /usr/local

INPUT/OUTPUT MAP

Notation below is roughly: inputs --> programs --> outputs

DEVELOPER runs these:

configure.ac -> autoconf -> configure (script) --- (*.ac = autoconf)
configure.in --> autoconf -> configure (script) --- (configure.in depreciated. Use configure.ac)

Makefile.am -> automake -> Makefile.in ----------- (*.am = automake)

INSTALLER runs these:

Makefile.in -> configure -> Makefile (*.in = input file)

Makefile -> make ----------> (puts new software in your downloads or temporary directory)
Makefile -> make install -> (puts new software in system directories)

"autoconf is an extensible package of M4 macros that produce shell scripts to automatically configure software source code packages. These scripts can adapt the packages to many kinds of UNIX-like systems without manual user intervention. Autoconf creates a configuration script for a package from a template file that lists the operating system features that the package can use, in the form of M4 macro calls."

"automake is a tool for automatically generating Makefile.in files compliant with the GNU Coding Standards. Automake requires the use of Autoconf."

Manuals:

• GNU AutoTools (The definitive manual on this stuff)

• m4 (used by autoconf)

• autoconf

• automake

Free online tutorials:

• Using GNU Autotools

Example:

The main configure.ac used to build LibreOffice is over 12k lines of code, (but there are also 57 other configure.ac files in subfolders.)

From this my generated configure is over 41k lines of code.

And while the Makefile.in and Makefile are both only 493 lines of code. (But, there are also 768 more Makefile.in's in subfolders.)

Yes you can, in your case:

vector<int>TestVector;`
for(int i=0;i<5;i++)
{

    TestVector.push_back(2+3*i);
    
} 

The S parameter does not do anything on its own.

/S      Modifies the treatment of string after /C or /K (see below) 
/C      Carries out the command specified by string and then terminates  
/K      Carries out the command specified by string but remains  

Try something like this instead

Call Shell("cmd.exe /S /K" & "perl a.pl c:\temp", vbNormalFocus)

You may not even need to add "cmd.exe" to this command unless you want a command window to open up when this is run. Shell should execute the command on its own.

Shell("perl a.pl c:\temp")

-Edit-
To wait for the command to finish you will have to do something like @Nate Hekman shows in his answer here

Dim wsh As Object
Set wsh = VBA.CreateObject("WScript.Shell")
Dim waitOnReturn As Boolean: waitOnReturn = True
Dim windowStyle As Integer: windowStyle = 1

wsh.Run "cmd.exe /S /C perl a.pl c:\temp", windowStyle, waitOnReturn

The method you are looking for is jQuery's .text() and you can used it in the following fashion:

$('#a_tbnotesverbergen').text('text here');

As a visual person, I like to weigh in with a sequence diagram of the proxy pattern. If you don't know how to read the arrows, I read the first one like this: Client executes Proxy.method().

1. The client calls a method on the target from his perspective, and is silently intercepted by the proxy
2. If a before aspect is defined, the proxy will execute it
3. Then, the actual method (target) is executed
4. After-returning and after-throwing are optional aspects that are executed after the method returns and/or if the method throws an exception
5. After that, the proxy executes the after aspect (if defined)
6. Finally the proxy returns to the calling client

(I was allowed to post the photo on condition that I mentioned its origins. Author: Noel Vaes, website: www.noelvaes.eu)

Object doesn't support this property or method.

Think of it like if anything after the dot is called on an object. It's like a chain.

An object is a class instance. A class instance supports some properties defined in that class type definition. It exposes whatever intelli-sense in VBE tells you (there are some hidden members but it's not related to this). So after each dot . you get intelli-sense (that white dropdown) trying to help you pick the correct action.

(you can start either way - front to back or back to front, once you understand how this works you'll be able to identify where the problem occurs)

Type this much anywhere in your code area

Dim a As Worksheets
a.

you get help from VBE, it's a little dropdown called Intelli-sense

It lists all available actions that particular object exposes to any user. You can't see the .Selection member of the Worksheets() class. That's what the error tells you exactly.

Object doesn't support this property or method.

If you look at the example on MSDN

Worksheets("GRA").Activate
iAreaCount = Selection.Areas.Count

It activates the sheet first then calls the Selection... it's not connected together because Selection is not a member of Worksheets() class. Simply, you can't prefix the Selection

What about

Sub DisplayColumnCount()
    Dim iAreaCount As Integer
    Dim i As Integer

    Worksheets("GRA").Activate
    iAreaCount = Selection.Areas.Count

    If iAreaCount <= 1 Then
        MsgBox "The selection contains " & Selection.Columns.Count & " columns."
    Else
        For i = 1 To iAreaCount
        MsgBox "Area " & i & " of the selection contains " & _
        Selection.Areas(i).Columns.Count & " columns."
        Next i
    End If
End Sub

from HERE

You can use recursion here to do this. For example:

jQuery(document).ready(checkContainer);

function checkContainer () {
  if($('#divIDer').is(':visible'))){ //if the container is visible on the page
    createGrid();  //Adds a grid to the html
  } else {
    setTimeout(checkContainer, 50); //wait 50 ms, then try again
  }
}

Basically, this function will check to make sure that the element exists and is visible. If it is, it will run your createGrid() function. If not, it will wait 50ms and try again.

Note:: Ideally, you would just use the callback function of your AJAX call to know when the container was appended, but this is a brute force, standalone approach. :)

Sleep causes thread to suspend itself for x milliseconds while yield suspends the thread and immediately moves it to the ready queue (the queue which the CPU uses to run threads).

I will let you decide if it's the fastest or not.

using System;
namespace PrimeNumbers
{

public static class Program
{
    static int primesCount = 0;


    public static void Main()
    {
        DateTime startingTime = DateTime.Now;

        RangePrime(1,1000000);   

        DateTime endingTime = DateTime.Now;

        TimeSpan span = endingTime - startingTime;

        Console.WriteLine("span = {0}", span.TotalSeconds);

    }


    public static void RangePrime(int start, int end)
    {
        for (int i = start; i != end+1; i++)
        {
            bool isPrime = IsPrime(i);
            if(isPrime)
            {
                primesCount++;
                Console.WriteLine("number = {0}", i);
            }
        }
        Console.WriteLine("primes count = {0}",primesCount);
    }



    public static bool IsPrime(int ToCheck)
    {

        if (ToCheck == 2) return true;
        if (ToCheck < 2) return false;


        if (IsOdd(ToCheck))
        {
            for (int i = 3; i <= (ToCheck / 3); i += 2)
            {
                if (ToCheck % i == 0) return false;
            }
            return true;
        }
        else return false; // even numbers(excluding 2) are composite
    }

    public static bool IsOdd(int ToCheck)
    {
        return ((ToCheck % 2 != 0) ? true : false);
    }
}
}

It takes approximately 82 seconds to find and print prime numbers within a range of 1 to 1,000,000, on my Core 2 Duo laptop with a 2.40 GHz processor. And it found 78,498 prime numbers.

At times, if we forget the

return self.cleaned_data 

in the clean function of django forms, we will not have any data though the form.is_valid() will return True.

Further modified based on answer from @Kyle as $.text() returns exact string, so the caret tag is printed literally, than as a markup, just in case someone would like to keep the caret intact in dropdown.

$(".dropdown-menu li").click(function(){
  $(this).parents(".btn-group").find('.btn').html(
  $(this).text()+" <span class=\"caret\"></span>"
  );
});

When you get the error message, you have the option to click on "Debug": this will lead you to the line where the error occurred. The Dark Canuck seems to be right, and I guess the error occurs on the line:

Sheets("Sheet1").protect Password:="btfd"

because most probably the "Sheet1" does not exist. However, if you say "It works fine, but when I save the file I get the message: run-time error '9': subscription out of range" it makes me think the error occurs on the second line:

ActiveWorkbook.Save

Could you please check this by pressing the Debug button first? And most important, as Gordon Bell says, why are you using a macro to protect a workbook?

At the moment there are three realy powerfull cmd.exe alternatives:

• cmder
  
• PowerCmd
• ComEmu
• Terminal for Windows 10
  

cmder is an enhancement off ConEmu and Clink

All have features like Copy & Paste, Window Resize per Mouse, Splitscreen, Tabs and a lot of other usefull features.

It looks like you're specifying both the EXE and its first argument in a single string e.g; '"C:\Program Files\Automated QA\TestExecute 8\Bin\TestExecute.exe" C:\temp\TestProject1\TestProject1.pjs /run /exit /SilentMode'. This won't work. In general you invoke a native command that has a space in its path like so:

& "c:\some path with spaces\foo.exe" <arguments go here>

That is & expects to be followed by a string that identifies a command: cmdlet, function, native exe relative or absolute path.

Once you get just this working:

& "c:\some path with spaces\foo.exe"

Start working on quoting of the arguments as necessary. Although it looks like your arguments should be just fine (no spaces, no other special characters interpreted by PowerShell).

From the GCC 4.2.1 manual, section -fwhole-program:

Assume that the current compilation unit represents whole program being compiled. All public functions and variables with the exception of main and those merged by attribute externally_visible become static functions and in a affect gets more aggressively optimized by interprocedural optimizers. While this option is equivalent to proper use of static keyword for programs consisting of single file, in combination with option --combine this flag can be used to compile most of smaller scale C programs since the functions and variables become local for the whole combined compilation unit, not for the single source file itself.

Give this a try:

var map = {"aaa": "rrr", "bbb": "ppp"};

The nearest equivalents would be icode and bcode as used by scalac, view Miguel Garcia's site on the Scalac optimiser for more information, here: http://magarciaepfl.github.io/scala/

You might also consider Java bytecode itself to be your intermediate representation, given that bytecode is the ultimate output of scalac.

Or perhaps the true intermediate is something that the JIT produces before it finally outputs native instructions?

Ultimately though... There's no single place that you can point at an claim "there's the intermediate!". Scalac works in phases that successively change the abstract syntax tree, every single phase produces a new intermediate. The whole thing is like an onion, and it's very hard to try and pick out one layer as somehow being more significant than any other.

This is a broad question and there are multiple ways you can achieve this. In my experience, I've seen a lot of single page applications having an entry point file such as index.js. This file would be responsible for 'bootstrapping' the application and will be your entry point for webpack.

index.js

import React from 'react';
import ReactDOM from 'react-dom';
import Application from './components/Application';

const root = document.getElementById('someElementIdHere');

ReactDOM.render(
  <Application />,
  root,
);

Your <Application /> component would contain the next pieces of your app. You've stated you want different pages and that leads me to believe you're using some sort of routing. That could be included into this component along with any libraries that need to be invoked on application start. react-router, redux, redux-saga, react-devtools come to mind. This way, you'll only need to add a single entry point into your webpack configuration and everything will trickle down in a sense.

When you've setup a router, you'll have options to set a component to a specific matched route. If you had a URL of /about, you should create the route in whatever routing package you're using and create a component of About.js with whatever information you need.

This gives error:

int len;
scanf("%d",&len);
char str[len]="";

This also gives error:

int len=5;
char str[len]="";

But this works fine:

int len=5;
char str[len]; //so the problem lies with assignment not declaration

You need to put value in the following way:

str[0]='a';
str[1]='b'; //like that; and not like str="ab";

It works nicely.

You should use static_cast<char>(i) to cast the integer i to char.

reinterpret_cast should almost never be used, unless you want to cast one type into a fundamentally different type.

Also reinterpret_cast is machine dependent so safely using it requires complete understanding of the types as well as how the compiler implements the cast.

For more information about C++ casting see:

• When should static_cast, dynamic_cast, const_cast and reinterpret_cast be used?
• http://www.cplusplus.com/doc/tutorial/typecasting/.

Do you really want the result to come up in an input box? If not, consider a table with borders set to other than transparent and use

document.getElementById('sum').innerHTML = sum;

@rckoenes already showed you how to correctly get your data from the JSON string.

To the question you asked: EXC_BAD_ACCESS almost always comes when you try to access an object after it has been [auto-]released. This is not specific to JSON [de-]serialization but, rather, just has to do with you getting an object and then accessing it after it's been released. The fact that it came via JSON doesn't matter.

There are many-many pages describing how to debug this -- you want to Google (or SO) obj-c zombie objects and, in particular, NSZombieEnabled, which will prove invaluable to you in helping determine the source of your zombie objects. ("Zombie" is what it's called when you release an object but keep a pointer to it and try to reference it later.)

You could also try this:

<input type="submit" name="submitbutton1" value="submit1" />
<input type="submit" name="submitbutton2" value="submit2" />

Then in your default function you call the functions you want:

if( Request.Form["submitbutton1"] != null)
{
    // Code for function 1
}
else if(Request.Form["submitButton2"] != null )
{
    // code for function 2
}

When you open phpinfo() see if the thread safety is enable or not enable also see the version of php and see MSVC-- what is the number in place of -- and see the architecture these all things help u to get the suitable php driver

First line in the List API says it is an ordered collection (also known as a sequence). If you sort the list you can't maintain the order, so there is no TreeList in Java.
As API says Java List got inspired from Sequence and see the sequence properties http://en.wikipedia.org/wiki/Sequence_(mathematics)

It doesn't mean that you can't sort the list, but Java strict to his definition and doesn't provide sorted versions of lists by default.

We already have tons of options to get mean by group, adding one more from mosaic package.

mosaic::mean(speed~dive, data = df)
#dive1 dive2 
#0.579 0.440 

This returns a named numeric vector, if needed a dataframe we can wrap it in stack

stack(mosaic::mean(speed~dive, data = df))

#  values   ind
#1  0.579 dive1
#2  0.440 dive2

data

set.seed(123)
df <- data.frame(dive=factor(sample(c("dive1","dive2"),10,replace=TRUE)),
                 speed=runif(10))

The best way to understand is to simply think from top to bottom ( Large Desktops to Mobile Phones)

Firstly, as B3 is mobile first so if you use xs then the columns will be same from Large desktops to xs ( i recommend using xs or sm as this will keep everything the way you want on every screen size )

Secondly if you want to give different width to columns on different devices or resolutions, than you can add multiple classes e.g

the above will change the width according to the screen resolutions, REMEMBER i am keeping the total columns in each class = 12

I hope my answer would help!

Sorry for the necropost, but these solutions did not work for me. I'm on postgres 10. On Linux:

1. I had to change directory to my pg_hba.conf.
2. I had to edit the file to change method from peer to md5 as stated here
3. Restart the service: service postgresql-10 restart

4. Change directory to where my backup.sql was located and execute:
   psql postgres -d database_name -1 -f backup.sql

   -database_name is the name of my database

   -backup.sql is the name of my .sql backup file.

You can use below IsValidDate():

 public static bool IsValidDate(string value, string[] dateFormats)
    {
        DateTime tempDate;
        bool validDate = DateTime.TryParseExact(value, dateFormats, DateTimeFormatInfo.InvariantInfo, DateTimeStyles.None, ref tempDate);
        if (validDate)
            return true;
        else
            return false;
    }

And you can pass in the value and date formats. For example:

var data = "02-08-2019";
var dateFormats = {"dd.MM.yyyy", "dd-MM-yyyy", "dd/MM/yyyy"}

if (IsValidDate(data, dateFormats))
{
    //Do something
}
else
{
    //Do something else
}

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

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

Resolution in this answer:

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

        <Extension()>
    Public Function ToEnum(Of TEnum)(ByVal value As String, ByVal defaultValue As TEnum) As TEnum
        If String.IsNullOrEmpty(value) Then
            Return defaultValue
        End If

        Return [Enum].Parse(GetType(TEnum), value, True)
    End Function

Windows 8.1 add:

--allow-file-access-from-files

to the end of the target text box after the quotes.

EX: "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --allow-file-access-from-files

Works like a charm

The scalar formatter supports collecting the exponents. The docs are as follows:

class matplotlib.ticker.ScalarFormatter(useOffset=True, useMathText=False, useLocale=None) Bases: matplotlib.ticker.Formatter

Tick location is a plain old number. If useOffset==True and the data range is much smaller than the data average, then an offset will be determined such that the tick labels are meaningful. Scientific notation is used for data < 10^-n or data >= 10^m, where n and m are the power limits set using set_powerlimits((n,m)). The defaults for these are controlled by the axes.formatter.limits rc parameter.

your technique would be:

from matplotlib.ticker import ScalarFormatter
xfmt = ScalarFormatter()
xfmt.set_powerlimits((-3,3))  # Or whatever your limits are . . .
{{ Make your plot }}
gca().xaxis.set_major_formatter(xfmt)

To get the exponent displayed in the format x10^5, instantiate the ScalarFormatter with useMathText=True.

You could also use:

xfmt.set_useOffset(10000)

To get a result like this:

The short answer is that there is no guaranteed way to get the information you want, however there are heuristics that work almost always in practice. You might look at How do I find the location of the executable in C?. It discusses the problem from a C point of view, but the proposed solutions are easily transcribed into Python.

I'll give you a couple examples of using properties that might get the gears turning:

• Lazy Initialization: If you have a property of an object that's expensive to load, but isn't accessed all that much in normal runs of the code, you can delay its loading via the property. That way, it's just sitting there, but the first time another module tries to call that property, it checks if the underlying field is null - if it is, it goes ahead and loads it, unknown to the calling module. This can greatly speed up object initialization.
• Dirty Tracking: Which I actually learned about from my own question here on StackOverflow. When I have a lot of objects which values might have changed during a run, I can use the property to track if they need to be saved back to the database or not. If not a single property of an object has changed, the IsDirty flag won't get tripped, and therefore the saving functionality will skip over it when deciding what needs to get back to the database.

In node 10.14 , behind nginx, you can retrieve the ip by requesting it through nginx header like this:

proxy_set_header X-Real-IP $remote_addr;

Then in your app.js:

app.set('trust proxy', true);

After that, wherever you want it to appear:

var userIp = req.header('X-Real-IP') || req.connection.remoteAddress;

You can also use gdb instead of addr2line to examine memory address. Load executable file in gdb and print the name of a symbol which is stored at the address. 16 Examining the Symbol Table.

You only need these CSS properties in .container class of Bootstrap and you can put inside him the normal grid system without someone content of the container will be out of him (without scroll-x in the viewport).

HTML:

<div class="container">
    <div class="row">
        <div class="col-xs-12">
            Your content here!
            ...    
        </div>
    </div>
    ... more rows
</div>

CSS:

/* Bootstrap custom */
.container{
    padding-left: 0rem;
    padding-right: 0rem;
    overflow: hidden;
}

Please do This code - it worked

 AbstractApplicationContext context= new ClassPathXmlApplicationContext("spring-config.xml");

o/w: Delete main method class and recreate it while recreating please uncheck Inherited abstract method its worked

Sounds like you're looking for rbind:

> a<-matrix(nrow=10,ncol=5)
> b<-matrix(nrow=20,ncol=5)
> dim(rbind(a,b))
[1] 30  5

Similarly, cbind stacks the matrices horizontally.

I am not entirely sure what you mean by the last question ("Can I do this for matrices of different rows and columns.?")

I have faced the same parse sdk loading problem during eclipse startup like yours (Shown in image below)

The solution to above problem is to just delete(uninstall) the package Android Wear ARM EABI v7a system image available under Android 5.1.1 (API 22) if it's installed. (No need to uninstall whole 5.1.1 package). May be there is some eclipse bug with this package.

Finally restart eclipse to see your changes.

Edit: If the problem still exists, try removing other Android Wear package also (i.e Android Wear Intel x86 Atom System Image) as suggested by @Abhishek in comments below.

In my case found that the TestCaseSource has different number of argument than the parameter in test method.

[Test, TestCaseSource("DivideCases")]
public void DivideTest(int n, int d, int q)
{
    Assert.AreEqual( q, n / d );
}

static object[] DivideCases =
{
    new object[] { 12, 3 },
    new object[] { 12, 2 },
    new object[] { 12, 4 } 
};

Here each object array in DivideCases has two item which should be 3 as DivideTest method has 3 parameter.

iloc works based on integer positioning. So no matter what your row labels are, you can always, e.g., get the first row by doing

df.iloc[0]

or the last five rows by doing

df.iloc[-5:]

You can also use it on the columns. This retrieves the 3rd column:

df.iloc[:, 2]    # the : in the first position indicates all rows

You can combine them to get intersections of rows and columns:

df.iloc[:3, :3] # The upper-left 3 X 3 entries (assuming df has 3+ rows and columns)

On the other hand, .loc use named indices. Let's set up a data frame with strings as row and column labels:

df = pd.DataFrame(index=['a', 'b', 'c'], columns=['time', 'date', 'name'])

Then we can get the first row by

df.loc['a']     # equivalent to df.iloc[0]

and the second two rows of the 'date' column by

df.loc['b':, 'date']   # equivalent to df.iloc[1:, 1]

and so on. Now, it's probably worth pointing out that the default row and column indices for a DataFrame are integers from 0 and in this case iloc and loc would work in the same way. This is why your three examples are equivalent. If you had a non-numeric index such as strings or datetimes, df.loc[:5] would raise an error.

Also, you can do column retrieval just by using the data frame's __getitem__:

df['time']    # equivalent to df.loc[:, 'time']

Now suppose you want to mix position and named indexing, that is, indexing using names on rows and positions on columns (to clarify, I mean select from our data frame, rather than creating a data frame with strings in the row index and integers in the column index). This is where .ix comes in:

df.ix[:2, 'time']    # the first two rows of the 'time' column

I think it's also worth mentioning that you can pass boolean vectors to the loc method as well. For example:

 b = [True, False, True]
 df.loc[b] 

Will return the 1st and 3rd rows of df. This is equivalent to df[b] for selection, but it can also be used for assigning via boolean vectors:

df.loc[b, 'name'] = 'Mary', 'John'

Or you can create a form with action:mailto

<form action="mailto:[email protected]"> 

check this out.

http://webdesign.about.com/od/forms/a/aa072699mailto.htm

But this actually submits a form via email.Is this what you wanted? You can also use just

<button onclick=""> and then some javascript with it to ahieve this.

And you can make a <a> look like button. There can be a lot of ways to work this around. Do a little search.

Check if a modal is open

$('.modal:visible').length && $('body').hasClass('modal-open')

To attach an event listener

$(document).on('show.bs.modal', '.modal', function () {
    // run your validation... ( or shown.bs.modal )
});

Passing data in the request

You could either embed it as a hidden field in your form, or add it your forms action URL

 echo '<input type="hidden" name="myVariable" value="'.
     htmlentities($myVariable).'">';

or

echo '<form method="POST" action="Page2.php?myVariable='.
    urlencode($myVariable).'">";

Note this also illustrates the use of htmlentities and urlencode when passing data around.

Passing data in the session

If the data doesn't need to be passed to the client side, then sessions may be more appropriate. Simply call session_start() at the start of each page, and you can get and set data into the $_SESSION array.

Security

Since you state your value is actually a filename, you need to be aware of the security ramifications. If the filename has arrived from the client side, assume the user has tampered with the value. Check it for validity! What happens when the user passes the path to an important system file, or a file under their control? Can your script be used to "probe" the server for files that do or do not exist?

As you are clearly just getting started here, its worth reminding that this goes for any data which arrives in $_GET, $_POST or $_COOKIE - assume your worst enemy crafted the contents of those arrays, and code accordingly!

With jQuery, you can shallow copy with extend:

var copiedObject = jQuery.extend({}, originalObject)

subsequent changes to the copiedObject will not affect the originalObject, and vice versa.

Or to make a deep copy:

var copiedObject = jQuery.extend(true, {}, originalObject)

Newton's Method with integer arithmetic

If you wish to avoid non-integer operations you could use the method below. It basically uses Newton's Method modified for integer arithmetic.

/**
 * Test if the given number is a perfect square.
 * @param n Must be greater than 0 and less
 *    than Long.MAX_VALUE.
 * @return <code>true</code> if n is a perfect
 *    square, or <code>false</code> otherwise.
 */
public static boolean isSquare(long n)
{
    long x1 = n;
    long x2 = 1L;

    while (x1 > x2)
    {
        x1 = (x1 + x2) / 2L;
        x2 = n / x1;
    }

    return x1 == x2 && n % x1 == 0L;
}

This implementation can not compete with solutions that use Math.sqrt. However, its performance can be improved by using the filtering mechanisms described in some of the other posts.

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

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

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

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

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

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

To print ALL of the criteria, you could:

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

Page is a special case handler.

Generic Web handler (*.ashx, extension based processor) is the default HTTP handler for all Web handlers that do not have a UI and that include the @WebHandler directive.

ASP.NET page handler (*.aspx) is the default HTTP handler for all ASP.NET pages.

Among the built-in HTTP handlers there are also Web service handler (*.asmx) and Trace handler (trace.axd)

MSDN says:

An ASP.NET HTTP handler is the process (frequently referred to as the "endpoint") that runs in response to a request made to an ASP.NET Web application. The most common handler is an ASP.NET page handler that processes .aspx files. When users request an .aspx file, the request is processed by the page through the page handler.

The image below illustrates this:

As to your second question:

Does ashx handle more connections than aspx?

Don't think so (but for sure, at least not less than).

The below method worked for me, Kudos to github user : midnightcodr

Make sure You remove any nodejs/npm packages already installed.

sudo apt-get purge nodejs

sudo apt-get purge npm

Now Install Node js using the command below( Thanks to midnightcodr on github)

curl -L https://raw.github.com/midnightcodr/rpi_node_install/master/setup.sh | bash -s 0.10.24

Note that you can invoke node with command node and not nodejs.

Once node is installed , Install npm

sudo apt-get install npm

Pass the sheet name with the Range parameter of the DoCmd.TransferSpreadsheet Method. See the box titled "Worksheets in the Range Parameter" near the bottom of that page.

This code imports from a sheet named "temp" in a workbook named "temp.xls", and stores the data in a table named "tblFromExcel".

Dim strXls As String
strXls = CurrentProject.Path & Chr(92) & "temp.xls"
DoCmd.TransferSpreadsheet acImport, , "tblFromExcel", _
    strXls, True, "temp!"

Thanks a lot guys for your quick comments.

This is what i will be using now. Posting the function here so that somebody may use it.

public function getDayOfWeek($pTimezone)
{

    $userDateTimeZone = new DateTimeZone($pTimezone);
    $UserDateTime = new DateTime("now", $userDateTimeZone);

    $offsetSeconds = $UserDateTime->getOffset(); 
    //echo $offsetSeconds;

    return gmdate("l", time() + $offsetSeconds);

}

Report if you find any corrections.

This will work if you do not have too many expressions.

Example: ng-show="form.type === 'Limited Company' || form.type === 'Limited Partnership'"

For any more expressions than this use a controller.

Set max-width:80%; as an inline stylesheet

Here is a simple demo to create customview (compoundview) by inflating from xml

attrs.xml

<resources>

    <declare-styleable name="CustomView">
        <attr format="string" name="text"/>
        <attr format="reference" name="image"/>
    </declare-styleable>
</resources>

CustomView.kt

class CustomView @JvmOverloads constructor(context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0) :
        ConstraintLayout(context, attrs, defStyleAttr) {

    init {
        init(attrs)
    }

    private fun init(attrs: AttributeSet?) {
        View.inflate(context, R.layout.custom_layout, this)

        val ta = context.obtainStyledAttributes(attrs, R.styleable.CustomView)
        try {
            val text = ta.getString(R.styleable.CustomView_text)
            val drawableId = ta.getResourceId(R.styleable.CustomView_image, 0)
            if (drawableId != 0) {
                val drawable = AppCompatResources.getDrawable(context, drawableId)
                image_thumb.setImageDrawable(drawable)
            }
            text_title.text = text
        } finally {
            ta.recycle()
        }
    }
}

custom_layout.xml

We should use merge here instead of ConstraintLayout because

If we use ConstraintLayout here, layout hierarchy will be ConstraintLayout->ConstraintLayout -> ImageView + TextView => we have 1 redundant ConstraintLayout => not very good for performance

<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:parentTag="android.support.constraint.ConstraintLayout">

    <ImageView
        android:id="@+id/image_thumb"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        tools:ignore="ContentDescription"
        tools:src="@mipmap/ic_launcher" />

    <TextView
        android:id="@+id/text_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_constraintEnd_toEndOf="@id/image_thumb"
        app:layout_constraintStart_toStartOf="@id/image_thumb"
        app:layout_constraintTop_toBottomOf="@id/image_thumb"
        tools:text="Text" />

</merge>

Using activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <your_package.CustomView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="#f00"
        app:image="@drawable/ic_android"
        app:text="Android" />

    <your_package.CustomView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="#0f0"
        app:image="@drawable/ic_adb"
        app:text="ADB" />

</LinearLayout>

      $image = wp_get_attachment_url( $thumbnail_id );

          echo '<img src="' . $image . '" alt="" />';
      }
  }
}

No, you cannot set them all in a single statement.
At the general case, you need at least three properties:

border-color: red green white blue;
border-style: solid dashed dotted solid;
border-width: 1px 2px 3px 4px;

However, that would be quite messy. It would be more readable and maintainable with four:

border-top:    1px solid  #ff0;
border-right:  2px dashed #f0F;
border-bottom: 3px dotted #f00;
border-left:   5px solid  #09f;

I was facing this problem and the solution was to restart my modem (router). I could get connection for my app to internet after that.

I think the library I am using is not managing connections properly because it happeend just few times.

I installed PyLint but I was having the error Missing module docstringpylint(missing-module-docstring). So I found this answer with this config for pylint :

"python.linting.pylintEnabled": true,
"python.linting.pylintArgs": [
    "--disable=C0111", // missing docstring
    "--load-plugins=pylint_django,pylint_celery",
 ],

And now it works

For t-SQL I use the following query for varchar columns (shows the collation and is_null properties):

SELECT
    s.name
    , o.name as table_name
    , c.name as column_name
    , t.name as type
    , c.max_length
    , c.collation_name
    , c.is_nullable
FROM
    sys.columns c
    INNER JOIN sys.objects o ON (o.object_id = c.object_id)
    INNER JOIN sys.schemas s ON (s.schema_id = o.schema_id)
    INNER JOIN sys.types t ON (t.user_type_id = c.user_type_id)
WHERE
    s.name = 'dbo'
    AND t.name IN ('varchar') -- , 'char', 'nvarchar', 'nchar')
ORDER BY
    o.name, c.name

I have same problem with the most basic situation and my problem was solved with inserting this meta in the head:

<meta charset="UTF-8">

the character encoding (which is actually UTF-8) of the html document was not declared

func tableView(_ tableView: UITableView, editActionsForRowAt: IndexPath) -> [UITableViewRowAction]? {

  let share = UITableViewRowAction(style: .normal, title: "Share") { action, index in
    //handle like delete button
    print("share button tapped")
  }

  share.backgroundColor = .lightGray

  let delete = UITableViewRowAction(style: .normal, title: "Delete") { action, index in
    self.nameArray.remove(at: editActionsForRowAt.row)
    self.swipeTable.beginUpdates()
    self.swipeTable.deleteRows(at: [editActionsForRowAt], with: .right)
    self.swipeTable.endUpdates()

    print("delete button tapped")
  }

  delete.backgroundColor = .orange
  return [share,delete]
}

func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
  return true
}

You could use the helper function $query->num_rows()

It returns the number of rows returned by the query. You can use like this:

$query = $this->db->query('SELECT * FROM my_table');
echo $query->num_rows();

@Josh Lindsey already answered perfectly fine. But I want to add some information since I often use ssh.

Therefore just change:

git remote add origin [email protected]:/path/to/my_project.git

to:

git remote add origin ssh://[email protected]/path/to/my_project

Note that the colon between domain and path isn't there anymore.

In order to sort a list of tuples (<word>, <count>), for count in descending order and word in alphabetical order:

data = [
('betty', 1),
('bought', 1),
('a', 1),
('bit', 1),
('of', 1),
('butter', 2),
('but', 1),
('the', 1),
('was', 1),
('bitter', 1)]

I use this method:

sorted(data, key=lambda tup:(-tup[1], tup[0]))

and it gives me the result:

[('butter', 2),
('a', 1),
('betty', 1),
('bit', 1),
('bitter', 1),
('bought', 1),
('but', 1),
('of', 1),
('the', 1),
('was', 1)]

A lazy way of doing this if there are alot of tables to be deleted.

1. Get table using the below

   • For sql server - SELECT CONCAT(name,',') Table_Name FROM SYS.tables;
   • For oralce - SELECT CONCAT(TABLE_NAME,',') FROM SYS.ALL_TABLES;

2. Copy and paste the table names from the result set and paste it after the DROP command.

Add this extension in your code and change image color in storyboard itself.

end.

This will split a string with a given delimiter into an array of strings.

You can't detect the codepage, you need to be told it. You can analyse the bytes and guess it, but that can give some bizarre (sometimes amusing) results. I can't find it now, but I'm sure Notepad can be tricked into displaying English text in Chinese.

Anyway, this is what you need to read: The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!).

Specifically Joel says:

The Single Most Important Fact About Encodings

If you completely forget everything I just explained, please remember one extremely important fact. It does not make sense to have a string without knowing what encoding it uses. You can no longer stick your head in the sand and pretend that "plain" text is ASCII. There Ain't No Such Thing As Plain Text.

If you have a string, in memory, in a file, or in an email message, you have to know what encoding it is in or you cannot interpret it or display it to users correctly.

The blocksize is usually selected to maximize the "occupancy". Search on CUDA Occupancy for more information. In particular, see the CUDA Occupancy Calculator spreadsheet.

Maybe an old topic but if someone needs further help with this do the following for example (this puts the text in middle line of image if it has larger height then the text).

HTML:

<div class="row display-table">
    <div class="col-xs-12 col-sm-4 display-cell">
        img
    </div>
    <div class="col-xs-12 col-sm-8 display-cell">
        text
    </div>
</div>

CSS:

.display-table{
    display: table;
    table-layout: fixed;
}

.display-cell{
    display: table-cell;
    vertical-align: middle;
    float: none;
}

The important thing that I missed out on was "float: none;" since it got float left from bootstrap col attributes.

Cheers!

Use any of the following groupby and agg recipes.

# Setup
df = pd.DataFrame({
  'a': ['A', 'A', 'B', 'B', 'B', 'C'],
  'b': [1, 2, 5, 5, 4, 6],
  'c': ['x', 'y', 'z', 'x', 'y', 'z']
})
df

   a  b  c
0  A  1  x
1  A  2  y
2  B  5  z
3  B  5  x
4  B  4  y
5  C  6  z

To aggregate multiple columns as lists, use any of the following:

df.groupby('a').agg(list)
df.groupby('a').agg(pd.Series.tolist)

           b          c
a                      
A     [1, 2]     [x, y]
B  [5, 5, 4]  [z, x, y]
C        [6]        [z]

To group-listify a single column only, convert the groupby to a SeriesGroupBy object, then call SeriesGroupBy.agg. Use,

df.groupby('a').agg({'b': list})  # 4.42 ms 
df.groupby('a')['b'].agg(list)    # 2.76 ms - faster

a
A       [1, 2]
B    [5, 5, 4]
C          [6]
Name: b, dtype: object

In my case I was using the maven-dependency-plugin so in order to resolve the issue I had to add the following property:

  <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

See Apache Maven Resources Plugin / Specifying a character encoding scheme

<?php if ($foo) { ?>
    <div class="mydiv">Condition is true</div>
<?php } else { ?>
    <div class="myotherdiv">Condition is false</div>
<?php } ?>

A height of 100% for is, presumably, the height of your browser's inner window, because that is the height of its parent, the page. An auto height will be the minimum height of necessary to contain .

Are you on Windows? The underlying socket implementation on Windows seems not to support the SO_TIMEOUT option very well. See also this answer: setSoTimeout on a client socket doesn't affect the socket

using (SqlConnection conn = new SqlConnection())
using (SqlCommand cmd = conn.CreateCommand())
{
    cmd.CommandText = "INSERT INTO <table> (<date_column>) VALUES ('2010-01-01 12:00')";
    cmd.ExecuteNonQuery();
}

It's been awhile since I wrote this stuff, so this may not be perfect. but the general idea is there.

You can create a jQuery object from a JSON object:

$.getJSON(url, data, function(json) {
    $(json).each(function() {
        /* YOUR CODE HERE */
    });
});

You can set the value in the HTML and then init datepicker to start/highlight the actual date

<input name="datefrom" type="text" class="datepicker" value="20-1-2011">
<input name="dateto" type="text" class="datepicker" value="01-01-2012">
<input name="dateto2" type="text" class="datepicker" >


$(".datepicker").each(function() {    
    $(this).datepicker('setDate', $(this).val());
});

The above even works with danish date formats

We can use summary on factor column:

summary(myDF$factorColumn)

I am listing the difference in each of the casting ways. What a particular type of casting handles and it doesn't?

    // object to int
    // does not handle null
    // does not handle NAN ("102art54")
    // convert value to integar
    int intObj = (int)obj;

    // handles only null or number
    int? nullableIntObj = (int?)obj; // null
    Nullable<int> nullableIntObj1 = (Nullable<int>)obj; // null

   // best way for casting from object to nullable int
   // handles null 
   // handles other datatypes gives null("sadfsdf") // result null
    int? nullableIntObj2 = obj as int?; 

    // string to int 
    // does not handle null( throws exception)
    // does not string NAN ("102art54") (throws exception)
    // converts string to int ("26236")
    // accepts string value
    int iVal3 = int.Parse("10120"); // throws exception value cannot be null;

    // handles null converts null to 0
    // does not handle NAN ("102art54") (throws exception)
    // converts obj to int ("26236")
    int val4 = Convert.ToInt32("10120"); 

    // handle null converts null to 0
    // handle NAN ("101art54") converts null to 0
    // convert string to int ("26236")
    int number;

    bool result = int.TryParse(value, out number);

    if (result)
    {
        // converted value
    }
    else
    {
        // number o/p = 0
    }

There is no way in Selenium to read the request or response headers. You could do it by instructing your browser to connect through a proxy that records this kind of information.

Setting the User Agent in Firefox

The usual way to change the user agent for Firefox is to set the variable "general.useragent.override" in your Firefox profile. Note that this is independent from Selenium.

You can direct Selenium to use a profile different from the default one, like this:

from selenium import webdriver
profile = webdriver.FirefoxProfile()
profile.set_preference("general.useragent.override", "whatever you want")
driver = webdriver.Firefox(profile)

Setting the User Agent in Chrome

With Chrome, what you want to do is use the user-agent command line option. Again, this is not a Selenium thing. You can invoke Chrome at the command line with chrome --user-agent=foo to set the agent to the value foo.

With Selenium you set it like this:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
opts = Options()
opts.add_argument("user-agent=whatever you want")

driver = webdriver.Chrome(chrome_options=opts)

Both methods above were tested and found to work. I don't know about other browsers.

Getting the User Agent

Selenium does not have methods to query the user agent from an instance of WebDriver. Even in the case of Firefox, you cannot discover the default user agent by checking what general.useragent.override would be if not set to a custom value. (This setting does not exist before it is set to some value.)

Once the browser is started, however, you can get the user agent by executing:

agent = driver.execute_script("return navigator.userAgent")

The agent variable will contain the user agent.

You can style li elements differently based on their class, their id or their ancestor elements:

li { /* styles all li elements*/
    list-style-type: none;
}

#ParentListID li { /* styles the li elements that have an ancestor element
                      of id="ParentListID" */
    list-style-type: bullet;
}

li.className { /* styles li elements of class="className" */
    list-style-type: bullet;
}

Or, to use the ancestor elements:

#navigationContainerID li { /* specifically styles the li elements with an ancestor of
                               id="navigationContainerID" */
    list-style-type: none;
}

li { /* then styles all other li elements that don't have that ancestor element */
    list-style-type: bullet;
}

Talking about functional PHP, I have this more generic answer:

    array_map(function($arr){
        $ret = $arr;
        $ret['value'] = $ret['url'];
        unset($ret['url']);
        return $ret;
    }, $tag);
}

As seen in Install crontab on CentOS, the crontab package in CentOS is vixie-cron. Hence, do install it with:

yum install vixie-cron

And then start it with:

service crond start

To make it persistent, so that it starts on boot, use:

chkconfig crond on

On CentOS 7 you need to use cronie:

yum install cronie

On CentOS 6 you can install vixie-cron, but the real package is cronie:

yum install vixie-cron

and

yum install cronie

In both cases you get the same output:

Python really tries hard to intelligently set sys.path. How it is set can get really complicated. The following guide is a watered-down, somewhat-incomplete, somewhat-wrong, but hopefully-useful guide for the rank-and-file python programmer of what happens when python figures out what to use as the initial values of sys.path, sys.executable, sys.exec_prefix, and sys.prefix on a normal python installation.

First, python does its level best to figure out its actual physical location on the filesystem based on what the operating system tells it. If the OS just says "python" is running, it finds itself in $PATH. It resolves any symbolic links. Once it has done this, the path of the executable that it finds is used as the value for sys.executable, no ifs, ands, or buts.

Next, it determines the initial values for sys.exec_prefix and sys.prefix.

If there is a file called pyvenv.cfg in the same directory as sys.executable or one directory up, python looks at it. Different OSes do different things with this file.

One of the values in this config file that python looks for is the configuration option home = <DIRECTORY>. Python will use this directory instead of the directory containing sys.executable when it dynamically sets the initial value of sys.prefix later. If the applocal = true setting appears in the pyvenv.cfg file on Windows, but not the home = <DIRECTORY> setting, then sys.prefix will be set to the directory containing sys.executable.

Next, the PYTHONHOME environment variable is examined. On Linux and Mac, sys.prefix and sys.exec_prefix are set to the PYTHONHOME environment variable, if it exists, superseding any home = <DIRECTORY> setting in pyvenv.cfg. On Windows, sys.prefix and sys.exec_prefix is set to the PYTHONHOME environment variable, if it exists, unless a home = <DIRECTORY> setting is present in pyvenv.cfg, which is used instead.

Otherwise, these sys.prefix and sys.exec_prefix are found by walking backwards from the location of sys.executable, or the home directory given by pyvenv.cfg if any.

If the file lib/python<version>/dyn-load is found in that directory or any of its parent directories, that directory is set to be to be sys.exec_prefix on Linux or Mac. If the file lib/python<version>/os.py is is found in the directory or any of its subdirectories, that directory is set to be sys.prefix on Linux, Mac, and Windows, with sys.exec_prefix set to the same value as sys.prefix on Windows. This entire step is skipped on Windows if applocal = true is set. Either the directory of sys.executable is used or, if home is set in pyvenv.cfg, that is used instead for the initial value of sys.prefix.

If it can't find these "landmark" files or sys.prefix hasn't been found yet, then python sets sys.prefix to a "fallback" value. Linux and Mac, for example, use pre-compiled defaults as the values of sys.prefix and sys.exec_prefix. Windows waits until sys.path is fully figured out to set a fallback value for sys.prefix.

Then, (what you've all been waiting for,) python determines the initial values that are to be contained in sys.path.

1. The directory of the script which python is executing is added to sys.path. On Windows, this is always the empty string, which tells python to use the full path where the script is located instead.
2. The contents of PYTHONPATH environment variable, if set, is added to sys.path, unless you're on Windows and applocal is set to true in pyvenv.cfg.
3. The zip file path, which is <prefix>/lib/python35.zip on Linux/Mac and os.path.join(os.dirname(sys.executable), "python.zip") on Windows, is added to sys.path.
4. If on Windows and no applocal = true was set in pyvenv.cfg, then the contents of the subkeys of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ are added, if any.
5. If on Windows and no applocal = true was set in pyvenv.cfg, and sys.prefix could not be found, then the core contents of the of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ is added, if it exists;
6. If on Windows and no applocal = true was set in pyvenv.cfg, then the contents of the subkeys of the registry key HK_LOCAL_MACHINE\Software\Python\PythonCore\<DLLVersion>\PythonPath\ are added, if any.
7. If on Windows and no applocal = true was set in pyvenv.cfg, and sys.prefix could not be found, then the core contents of the of the registry key HK_CURRENT_USER\Software\Python\PythonCore\<DLLVersion>\PythonPath\ is added, if it exists;
8. If on Windows, and PYTHONPATH was not set, the prefix was not found, and no registry keys were present, then the relative compile-time value of PYTHONPATH is added; otherwise, this step is ignored.
9. Paths in the compile-time macro PYTHONPATH are added relative to the dynamically-found sys.prefix.
10. On Mac and Linux, the value of sys.exec_prefix is added. On Windows, the directory which was used (or would have been used) to search dynamically for sys.prefix is added.

At this stage on Windows, if no prefix was found, then python will try to determine it by searching all the directories in sys.path for the landmark files, as it tried to do with the directory of sys.executable previously, until it finds something. If it doesn't, sys.prefix is left blank.

Finally, after all this, Python loads the site module, which adds stuff yet further to sys.path:

It starts by constructing up to four directories from a head and a tail part. For the head part, it uses sys.prefix and sys.exec_prefix; empty heads are skipped. For the tail part, it uses the empty string and then lib/site-packages (on Windows) or lib/pythonX.Y/site-packages and then lib/site-python (on Unix and Macintosh). For each of the distinct head-tail combinations, it sees if it refers to an existing directory, and if so, adds it to sys.path and also inspects the newly added path for configuration files.

You can use the String constructor.

System.out.println(new String(new char[]{a,b,c}));

If you have a compiler that supports the alloca() function, then this is possible solution (quite ugly though):

printf("%s", (char*)memset(memset(alloca(10), '\0', 10), 'x', 9));

It basically allocates 10 bytes on the stack which are filled with '\0' and then the first 9 bytes are filled with 'x'.

If you have a C99 compiler, then this might be a neater solution:

for (int i = 0;  i < 10;  i++, printf("%c", 'x'));

If you're using .NET 4.0 or above and you want a programmatic version that isn't a codification of rules defined outside of code, you can create an Expression, compile and run it on-the-fly.

The following extension method will take a Type and get the value returned from default(T) through the Default method on the Expression class:

public static T GetDefaultValue<T>()
{
    // We want an Func<T> which returns the default.
    // Create that expression here.
    Expression<Func<T>> e = Expression.Lambda<Func<T>>(
        // The default value, always get what the *code* tells us.
        Expression.Default(typeof(T))
    );

    // Compile and return the value.
    return e.Compile()();
}

public static object GetDefaultValue(this Type type)
{
    // Validate parameters.
    if (type == null) throw new ArgumentNullException("type");

    // We want an Func<object> which returns the default.
    // Create that expression here.
    Expression<Func<object>> e = Expression.Lambda<Func<object>>(
        // Have to convert to object.
        Expression.Convert(
            // The default value, always get what the *code* tells us.
            Expression.Default(type), typeof(object)
        )
    );

    // Compile and return the value.
    return e.Compile()();
}

You should also cache the above value based on the Type, but be aware if you're calling this for a large number of Type instances, and don't use it constantly, the memory consumed by the cache might outweigh the benefits.

0.0 is a double literal and this is not considered as absolute zero! No exception because it is considered that the double variable large enough to hold the values representing near infinity!

I am using chrome, Linux Mint; and for commenting and dis-commenting bundle of lines:

Ctrl + /

You can generate a key by the following command:

php artisan key:generate 

The key will be written automatically in your .env file.

APP_KEY=YOUR_GENERATED_KEY

If you want to see your key after generation use --show option

php artisan key:generate --show

Note: The .env is a hidden file in your project folder.

In vim if you are confused which all lines will be affected, Use below

 :%s/foo/bar/gc  

Change each 'foo' to 'bar', but ask for confirmation first. Press 'y' for yes and 'n' for no. Dont forget to save after that

:wq

In python 2 you can do it with: raw_input()

>>print("Hello World!")    
>>raw_input('Waiting a key...')

In python 3 you can do it with: input()

>>print("Hello world!")    
>>input('Waiting a key...')

Also, you can do it with the time.sleep(time)

>>import time
>>print("The program will close in 5 seconds")
>>time.sleep(5)

If you don't want to use DI or Factories. You can refactor your class in a little tricky way:

public class Foo {
    private Bar bar;

    public void foo(Bar bar){
        this.bar = (bar != null) ? bar : new Bar();
        bar.someMethod();
        this.bar = null;  // for simulating local scope
    }
}

And your test class:

@RunWith(MockitoJUnitRunner.class)
public class FooTest {
    @Mock Bar barMock;
    Foo foo;

    @Test
    public void testFoo() {
       foo = new Foo();
       foo.foo(barMock);
       verify(barMock, times(1)).someMethod();
    }
}

Then the class that is calling your foo method will do it like this:

public class thirdClass {

   public void someOtherMethod() {
      Foo myFoo = new Foo();
      myFoo.foo(null);
   }
}

As you can see when calling the method this way, you don't need to import the Bar class in any other class that is calling your foo method which is maybe something you want.

Of course the downside is that you are allowing the caller to set the Bar Object.

Hope it helps.
