Using Linux, the simplest way is to execute bash command

xrandr | grep '*'

and parse its output using regexp.

Also you can do it through PyGame: http://www.daniweb.com/forums/thread54881.html

I was finding somethig for make a filter passing an Object, then i can use it like multi-filter:

i did this Beauty Solution:

filter.pipe.ts

import { PipeTransform, Pipe } from '@angular/core';

@Pipe({
  name: 'filterx',
  pure: false
})
export class FilterPipe implements PipeTransform {
 transform(items: any, filter: any, isAnd: boolean): any {
  let filterx=JSON.parse(JSON.stringify(filter));
  for (var prop in filterx) {
    if (Object.prototype.hasOwnProperty.call(filterx, prop)) {
       if(filterx[prop]=='')
       {
         delete filterx[prop];
       }
    }
 }
if (!items || !filterx) {
  return items;
}

return items.filter(function(obj) {
  return Object.keys(filterx).every(function(c) {
    return obj[c].toLowerCase().indexOf(filterx[c].toLowerCase()) !== -1
  });
  });
  }
}

component.ts

slotFilter:any={start:'',practitionerCodeDisplay:'',practitionerName:''};

componet.html

             <tr>
                <th class="text-center">  <input type="text" [(ngModel)]="slotFilter.start"></th>
                <th class="text-center"><input type="text" [(ngModel)]="slotFilter.practitionerCodeDisplay"></th>
                <th class="text-left"><input type="text" [(ngModel)]="slotFilter.practitionerName"></th>
                <th></th>
              </tr>


 <tbody *ngFor="let item of practionerRoleList | filterx: slotFilter">...

$('input[type="submit"]').click(function(){
$(this).css('color','red');
});

Use class, Demo:- http://jsfiddle.net/BX6Df/

   $('input[type="submit"]').click(function(){
          $(this).addClass('red');
});

if you want to toggle the color each click, you can try this:- http://jsfiddle.net/SMNks/

$('input[type="submit"]').click(function(){
  $(this).toggleClass('red');
});


.red
{
    background-color:red;
}

Updated answer for your comment.

http://jsfiddle.net/H2Xhw/

$('input[type="submit"]').click(function(){
    $('input[type="submit"].red').removeClass('red')
        $(this).addClass('red');
});

To elaborate on Ignacio Vazquez-Abrams's answer:

The Python import mechanism works relative to the __name__ of the current file. When you execute a file directly, it doesn't have its usual name, but has "__main__" as its name instead. So relative imports don't work.

You can, as Igancio suggested, execute it using the -m option. If you have a part of your package that is meant to be run as a script, you can also use the __package__ attribute to tell that file what name it's supposed to have in the package hierarchy.

See http://www.python.org/dev/peps/pep-0366/ for details.

PERSISTENT, definitive solution

Add this line to your ~/.screenrc

termcapinfo xterm* ti@:te@

Now you can create a screen, and scroll it up/down with your mouse; Like you normally do.

On Kotlin you can set width and height of any view directly using their virtual properties:

someView.layoutParams.width = 100
someView.layoutParams.height = 200

Here is what I came up with and this is with not much lines of code

function show_files($start) {
    $contents = scandir($start);
    array_splice($contents, 0,2);
    echo "<ul>";
    foreach ( $contents as $item ) {
        if ( is_dir("$start/$item") && (substr($item, 0,1) != '.') ) {
            echo "<li>$item</li>";
            show_files("$start/$item");
        } else {
            echo "<li>$item</li>";
        }
    }
    echo "</ul>";
}

show_files('./');

It outputs something like

..idea
.add.php
.add_task.php
.helpers
 .countries.php
.mysqli_connect.php
.sort.php
.test.js
.test.php
.view_tasks.php

Hope this helps.

I don't think this solves the problem to the first questioner, but for googlers coming here for answers:

On update 51, java 1.8 prohibited[1] RC4 ciphers by default, as we can see on the Release Notes page:

Bug Fix: Prohibit RC4 cipher suites

RC4 is now considered as a compromised cipher.

RC4 cipher suites have been removed from both client and server default enabled cipher suite list in Oracle JSSE implementation. These cipher suites can still be enabled by SSLEngine.setEnabledCipherSuites() and SSLSocket.setEnabledCipherSuites() methods. See JDK-8077109 (not public).

If your server has a strong preference for this cipher (or use only this cipher) this can trigger a handshake_failure on java.

You can test connecting to the server enabling RC4 ciphers (first, try without enabled argument to see if triggers a handshake_failure, then set enabled:

Simplest way? It works. :)

try using:

RAISERROR('your message here!!!',0,1) WITH NOWAIT

you could also try switching to "Results to Text" it is just a few icons to the right of "Execute" on the default tool bar.

With both of the above in place, and you still you do not see the messages, make sure you are running the same server/database/owner version of the procedure that you are editing. Make sure you are hitting the RAISERROR command, make it the first command inside the procedure.

If all else fails, you could create a table:

create table temp_log (RowID int identity(1,1) primary key not null
                      , MessageValue varchar(255))

then:

INSERT INTO temp_log VALUES ('Your message here')

then after running the procedure (provided no rollbacks) just select the table.

Try this

new_df = pd.merge(A_df, B_df,  how='left', left_on=['A_c1','c2'], right_on = ['B_c1','c2'])

https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.merge.html

left_on : label or list, or array-like Field names to join on in left DataFrame. Can be a vector or list of vectors of the length of the DataFrame to use a particular vector as the join key instead of columns

right_on : label or list, or array-like Field names to join on in right DataFrame or vector/list of vectors per left_on docs

use below method to delete entire main directory which contains files and it's sub directory. After calling this method once again call delete() directory of your main directory.

// For to Delete the directory inside list of files and inner Directory
public static boolean deleteDir(File dir) {
    if (dir.isDirectory()) {
        String[] children = dir.list();
        for (int i=0; i<children.length; i++) {
            boolean success = deleteDir(new File(dir, children[i]));
            if (!success) {
                return false;
            }
        }
    }

    // The directory is now empty so delete it
    return dir.delete();
}

I've been trying to get this code to work for the last 2 hours and though it showed no error on the simulator, there was one on the device.

Turns out, at least in my case that the error came from directory used (bundle) :

NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/recordTest.caf", [[NSBundle mainBundle] resourcePath]]];

It was not writable or something like this... There was no error except the fact that prepareToRecord failed...

I therefore replaced it by :

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *recDir = [paths objectAtIndex:0];
NSURL *url = [NSURL fileURLWithPath:[NSString stringWithFormat:@"%@/recordTest.caf", recDir]]

It now Works like a Charm.

Hope this helps others.

For whatever reason the above would not work for me. This is what did:

if (tabControl.SelectedTab.Name == "tabName" )
{
     .. do stuff
}

where tabControl.SelectedTab.Name is the name attribute assigned to the page in the tabcontrol itself.

Here is an example code to compress a Whole Directory(including sub files and sub directories), it's using the walk file tree feature of Java NIO.

import java.io.FileOutputStream;
import java.io.IOException;
import java.nio.file.*;
import java.nio.file.attribute.BasicFileAttributes;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;

public class ZipCompress {
    public static void compress(String dirPath) {
        final Path sourceDir = Paths.get(dirPath);
        String zipFileName = dirPath.concat(".zip");
        try {
            final ZipOutputStream outputStream = new ZipOutputStream(new FileOutputStream(zipFileName));
            Files.walkFileTree(sourceDir, new SimpleFileVisitor<Path>() {
                @Override
                public FileVisitResult visitFile(Path file, BasicFileAttributes attributes) {
                    try {
                        Path targetFile = sourceDir.relativize(file);
                        outputStream.putNextEntry(new ZipEntry(targetFile.toString()));
                        byte[] bytes = Files.readAllBytes(file);
                        outputStream.write(bytes, 0, bytes.length);
                        outputStream.closeEntry();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                    return FileVisitResult.CONTINUE;
                }
            });
            outputStream.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

To use this, just call

ZipCompress.compress("target/directoryToCompress");

and you'll get a zip file directoryToCompress.zip

It's good practice to use a StringBuilder when concatenating a lot of strings and you can then use the Remove method to get rid of the final character.

StringBuilder paramBuilder = new StringBuilder();

foreach (var item in itemsToAdd)
{
    paramBuilder.AppendFormat(("productID={0}&", item.prodID.ToString());
}

if (paramBuilder.Length > 1)
    paramBuilder.Remove(paramBuilder.Length-1, 1);

string s = paramBuilder.ToString();

In relative layout you need specify textview height:

android:layout_height="100dp"

Or specify lines attribute:

android:lines="3"

I had the same issue recently and ended up creating a NuGet package for this.

This implements a standard heap-based priority queue. It also has all the usual niceties of the BCL collections: ICollection<T> and IReadOnlyCollection<T> implementation, custom IComparer<T> support, ability to specify an initial capacity, and a DebuggerTypeProxy to make the collection easier to work with in the debugger.

There is also an Inline version of the package which just installs a single .cs file into your project (useful if you want to avoid taking externally-visible dependencies).

More information is available on the github page.

No, Java doesn't have that ability.

It does have System.nanoTime(), but that just gives an offset from some previously known time. So whilst you can't take the absolute number from this, you can use it to measure nanosecond (or higher) precision.

Note that the JavaDoc says that whilst this provides nanosecond precision, that doesn't mean nanosecond accuracy. So take some suitably large modulus of the return value.

send a string to this function. it will first check string is empty or null, if not string will be all lower chars. then return first char of string upper rest of them lower.

string FirstUpper(string s)
    {
        // Check for empty string.
        if (string.IsNullOrEmpty(s))
        {
            return string.Empty;
        }
        s = s.ToLower();
        // Return char and concat substring.
        return char.ToUpper(s[0]) + s.Substring(1);
    }

1.The +(operator) has not effect to that in using EL. 2.so this is the way,to use that

<c:set var="enabled" value="${value} enabled" />


<c:out value="${empty value ? 'none' : enabled}" />

is this helpful to You ?

First of all go to the device manager now go to View>>select Show hidden devices....Then go to network adapters and find out Microsoft Hosted network Virual Adapter ....Press right click and enable the option....

Then go to command prompt with administrative privileges and enter the following commands:

netsh wlan set hostednetwork mode=allow
netsh wlan start hostednetwork

Your Hostednetwork will work without any problems.

I really had high hopes for dompdf (it is a cool idea) but the positioning issue are a major factor in my using fpdf. Though it is tedious as every element has to be set; it is powerful as all get out.

I lay an image underneath my workspace in the document to put my layout on top of to fit. Its always been sufficient even for columns (requires a tiny bit of php string calculation, but nothing too terribly heady).

Good luck.

In my case, Windows had ran an update and was waiting to restart the PC. I hadn't seen any notifications but, well... turning it off and turning it on again fixed the problem.

Try that first before monkeying with any of these Visual Studio directories and applications.

Most answers are brittle because they rely on the order of the SP's parameters. Better to name the Stored Proc's params and give parameterized values to those.

In order to use Named params when calling your SP, without worrying about the order of parameters

Using SQL Server named parameters with ExecuteStoreQuery and ExecuteStoreCommand

Describes the best approach. Better than Dan Mork's answer here.

• Doesn't rely on concatenating strings, and doesn't rely on the order of parameters defined in the SP.

E.g.:

var cmdText = "[DoStuff] @Name = @name_param, @Age = @age_param";
var sqlParams = new[]{
   new SqlParameter("name_param", "Josh"),
   new SqlParameter("age_param", 45)
};

context.Database.SqlQuery<myEntityType>(cmdText, sqlParams)

Here is a generic set of code that I frequently use to rearrange the position of columns. You may find it useful.

cols = df.columns.tolist()
n = int(cols.index('Mid'))
cols = [cols[n]] + cols[:n] + cols[n+1:]
df = df[cols]

A much simpler way to do this is to use split():

String match = "123woods";
String text = "I will come and meet you at the 123woods";

String[] sentence = text.split();
for(String word: sentence)
{
    if(word.equals(match))
        return true;
}
return false;

This is a simpler, less elegant way to do the same thing without using tokens, etc.

The call() method calls a function with a given this value and arguments provided individually.

apply() - Similar to the call() method, the first parameter in the apply() method sets the this value which is the object upon which the function is invoked. In this case, it's the obj object above. The only difference between the apply() and call() method is that the second parameter of the apply() method accepts the arguments to the actual function as an array.

While working with selected cells as shown by @tbur can be useful, it's also not the only option available.

You can use Range() like so:

If Worksheets("Sheet1").Range("A1").MergeCells Then
  Do something
Else
  Do something else
End If

Or:

If Worksheets("Sheet1").Range("A1:C1").MergeCells Then
  Do something
Else
  Do something else
End If

Alternately, you can use Cells():

If Worksheets("Sheet1").Cells(1, 1).MergeCells Then
  Do something
Else
  Do something else
End If

You're looking for the DayOfWeek property.

Here's the msdn article.

I got this same error when i was trying to make a table with name "admin". Then I used @Table annotation and gave table a different name like @Table(name = "admins"). I think some words are reserved (like :- keywords in java) and you can not use them.

@Entity
@Table(name = "admins")
public class Admin extends TrackedEntity {

}

I'd personally make use of the table.insert function:

table.insert(a,"b");

This saves you from having to iterate over the whole table therefore saving valuable resources such as memory and time.

You question could be reformulated as "replace in the string the first space and everything following by nothing" . So this can be achieved with a simple regular expression:

$firstWord = preg_replace("/\s.*/", '', ltrim($myvalue));

I have added an optional call to ltrim() to be safe: this function remove spaces at the begin of string.

You need to add confirm() to your deleteItem();

function deleteItem() {
    if (confirm("Are you sure?")) {
        // your deletion code
    }
    return false;
}

These are the necersary imports:

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

And this is a method that will allow you to read from a File by passing it the filename as a parameter like this: readFile("yourFile.txt");

String readFile(String fileName) throws IOException {
    BufferedReader br = new BufferedReader(new FileReader(fileName));
    try {
        StringBuilder sb = new StringBuilder();
        String line = br.readLine();

        while (line != null) {
            sb.append(line);
            sb.append("\n");
            line = br.readLine();
        }
        return sb.toString();
    } finally {
        br.close();
    }
}

Always double check httpd.conf to see if document root is correctly pointing to an existing folder

#if you have c:\your-main-folder\www\
DocumentRoot "c:/your-main-folder/www/" 

#if you have c:\your-main-folder\www\sub-folder\
DocumentRoot "c:/your-main-folder/www/sub-folder/" 

DocumentRoot points to a folder that must exist in your drive.

For more general boolean functions that you would like to use as a filter and that depend on more than one column, you can use:

df = df[df[['col_1','col_2']].apply(lambda x: f(*x), axis=1)]

where f is a function that is applied to every pair of elements (x1, x2) from col_1 and col_2 and returns True or False depending on any condition you want on (x1, x2).

There are multiple options available for generating HTML reports for Selenium WebDriver scripts.

1. Use the JUNIT TestWatcher class for creating your own Selenium HTML reports

The TestWatcher JUNIT class allows overriding the failed() and succeeded() JUNIT methods that are called automatically when JUNIT tests fail or pass.

The TestWatcher JUNIT class allows overriding the following methods:

• protected void failed(Throwable e, Description description)

failed() method is invoked when a test fails

• protected void finished(Description description)

finished() method is invoked when a test method finishes (whether passing or failing)

• protected void skipped(AssumptionViolatedException e, Description description)

skipped() method is invoked when a test is skipped due to a failed assumption.

• protected void starting(Description description)

starting() method is invoked when a test is about to start

• protected void succeeded(Description description)

succeeded() method is invoked when a test succeeds

See below sample code for this case:

import static org.junit.Assert.assertTrue;
import org.junit.Test;

public class TestClass2 extends WatchManClassConsole {

    @Test public void testScript1() {
        assertTrue(1 < 2); >
    }

    @Test public void testScript2() {
        assertTrue(1 > 2);
    }

    @Test public void testScript3() {
        assertTrue(1 < 2);
    }

    @Test public void testScript4() {
        assertTrue(1 > 2);
    }
}

import org.junit.Rule; 
import org.junit.rules.TestRule; 
import org.junit.rules.TestWatcher; 
import org.junit.runner.Description; 
import org.junit.runners.model.Statement; 

public class WatchManClassConsole {

    @Rule public TestRule watchman = new TestWatcher() { 

        @Override public Statement apply(Statement base, Description description) { 
            return super.apply(base, description); 
        } 

        @Override protected void succeeded(Description description) { 
            System.out.println(description.getDisplayName() + " " + "success!"); 
        } 

        @Override protected void failed(Throwable e, Description description) { 
            System.out.println(description.getDisplayName() + " " + e.getClass().getSimpleName()); 
        }
    }; 
}

2. Use the Allure Reporting framework

Allure framework can help with generating HTML reports for your Selenium WebDriver projects.

The reporting framework is very flexible and it works with many programming languages and unit testing frameworks.

You can read everything about it at http://allure.qatools.ru/.

You will need the following dependencies and plugins to be added to your pom.xml file

1. maven surefire
2. aspectjweaver
3. allure adapter

See more details including code samples on this article: http://test-able.blogspot.com/2015/10/create-selenium-html-reports-with-allure-framework.html

instead of this

UPDATE staff SET salary = 1200 WHERE name = 'Bob';
UPDATE staff SET salary = 1200 WHERE name = 'Jane';
UPDATE staff SET salary = 1200 WHERE name = 'Frank';
UPDATE staff SET salary = 1200 WHERE name = 'Susan';
UPDATE staff SET salary = 1200 WHERE name = 'John';

you can use

UPDATE staff SET salary = 1200 WHERE name IN ('Bob', 'Frank', 'John');

In addition to @JBNizet's answer, my general use case for ifPresent is to combine .isPresent() and .get():

Old way:

Optional opt = getIntOptional();
if(opt.isPresent()) {
    Integer value = opt.get();
    // do something with value
}

New way:

Optional opt = getIntOptional();
opt.ifPresent(value -> {
    // do something with value
})

This, to me, is more intuitive.

Here's my expression dark theme for WPF controls.

I realize this question is for Swift, but here is the Xamarin equivalent code of the accepted answer if someone is interested.

var indexPath = NSIndexPath.FromRowSection(rowIndex, 0);
tableView.ReloadRows(new NSIndexPath[] { indexPath }, UITableViewRowAnimation.Top);

This sample shows how to read and write a string to a MemoryStream.

Imports System.IO

Module Module1
  Sub Main()
    ' We don't need to dispose any of the MemoryStream 
    ' because it is a managed object. However, just for 
    ' good practice, we'll close the MemoryStream.
    Using ms As New MemoryStream
      Dim sw As New StreamWriter(ms)
      sw.WriteLine("Hello World")
      ' The string is currently stored in the 
      ' StreamWriters buffer. Flushing the stream will 
      ' force the string into the MemoryStream.
      sw.Flush()
      ' If we dispose the StreamWriter now, it will close 
      ' the BaseStream (which is our MemoryStream) which 
      ' will prevent us from reading from our MemoryStream
      'sw.Dispose()

      ' The StreamReader will read from the current 
      ' position of the MemoryStream which is currently 
      ' set at the end of the string we just wrote to it. 
      ' We need to set the position to 0 in order to read 
      ' from the beginning.
      ms.Position = 0
      Dim sr As New StreamReader(ms)
      Dim myStr = sr.ReadToEnd()
      Console.WriteLine(myStr)

      ' We can dispose our StreamWriter and StreamReader 
      ' now, though this isn't necessary (they don't hold 
      ' any resources open on their own).
      sw.Dispose()
      sr.Dispose()
    End Using

    Console.WriteLine("Press any key to continue.")
    Console.ReadKey()
  End Sub
End Module

Transposing is inefficient for large DataFrames. Here is an alternative:

def duplicate_columns(frame):
    groups = frame.columns.to_series().groupby(frame.dtypes).groups
    dups = []
    for t, v in groups.items():
        dcols = frame[v].to_dict(orient="list")

        vs = dcols.values()
        ks = dcols.keys()
        lvs = len(vs)

        for i in range(lvs):
            for j in range(i+1,lvs):
                if vs[i] == vs[j]: 
                    dups.append(ks[i])
                    break

    return dups       

Use it like this:

dups = duplicate_columns(frame)
frame = frame.drop(dups, axis=1)

Edit

A memory efficient version that treats nans like any other value:

from pandas.core.common import array_equivalent

def duplicate_columns(frame):
    groups = frame.columns.to_series().groupby(frame.dtypes).groups
    dups = []

    for t, v in groups.items():

        cs = frame[v].columns
        vs = frame[v]
        lcs = len(cs)

        for i in range(lcs):
            ia = vs.iloc[:,i].values
            for j in range(i+1, lcs):
                ja = vs.iloc[:,j].values
                if array_equivalent(ia, ja):
                    dups.append(cs[i])
                    break

    return dups

Just put a '!' in front of the boolean expression

Just for fun, here some test:

I think you should not rely on the implicit conversion. It is a bad practice.

Instead you should try like this:

datenum >= to_date('11/26/2013','mm/dd/yyyy')

or like

datenum >= date '2013-09-01'

Based on Haim's answer here's a simplified example if you're looking to compare values that exist in BOTH tables, otherwise if there's a row in one table but not the other it will also return it....

Took me a couple of hours to figure out. Here's a fully tested simply query for comparing "tbl_a" and "tbl_b"

SELECT ID, col
FROM
(
    SELECT
    tbl_a.ID, tbl_a.col FROM tbl_a
    UNION ALL
    SELECT
    tbl_b.ID, tbl_b.col FROM tbl_b
) t
WHERE ID IN (select ID from tbl_a) AND ID IN (select ID from tbl_b)
GROUP BY
ID, col
HAVING COUNT(*) = 1
 ORDER BY ID

So you need to add the extra "where in" clause:

WHERE ID IN (select ID from tbl_a) AND ID IN (select ID from tbl_b)

Also:

For ease of reading if you want to indicate the table names you can use the following:

SELECT tbl, ID, col
FROM
(
    SELECT
    tbl_a.ID, tbl_a.col, "name_to_display1" as "tbl" FROM tbl_a
    UNION ALL
    SELECT
    tbl_b.ID, tbl_b.col, "name_to_display2" as "tbl" FROM tbl_b
) t
WHERE ID IN (select ID from tbl_a) AND ID IN (select ID from tbl_b)
GROUP BY
ID, col
HAVING COUNT(*) = 1
 ORDER BY ID

The Content-Security-Policy meta-tag allows you to reduce the risk of XSS attacks by allowing you to define where resources can be loaded from, preventing browsers from loading data from any other locations. This makes it harder for an attacker to inject malicious code into your site.

I banged my head against a brick wall trying to figure out why I was getting CSP errors one after another, and there didn't seem to be any concise, clear instructions on just how does it work. So here's my attempt at explaining some points of CSP briefly, mostly concentrating on the things I found hard to solve.

For brevity I won’t write the full tag in each sample. Instead I'll only show the content property, so a sample that says content="default-src 'self'" means this:

<meta http-equiv="Content-Security-Policy" content="default-src 'self'">

1. How can I allow multiple sources?

You can simply list your sources after a directive as a space-separated list:

content="default-src 'self' https://example.com/js/"

Note that there are no quotes around parameters other than the special ones, like 'self'. Also, there's no colon (:) after the directive. Just the directive, then a space-separated list of parameters.

Everything below the specified parameters is implicitly allowed. That means that in the example above these would be valid sources:

https://example.com/js/file.js
https://example.com/js/subdir/anotherfile.js

These, however, would not be valid:

http://example.com/js/file.js
^^^^ wrong protocol

https://example.com/file.js
                   ^^ above the specified path

2. How can I use different directives? What do they each do?

The most common directives are:

• default-src the default policy for loading javascript, images, CSS, fonts, AJAX requests, etc
• script-src defines valid sources for javascript files
• style-src defines valid sources for css files
• img-src defines valid sources for images
• connect-src defines valid targets for to XMLHttpRequest (AJAX), WebSockets or EventSource. If a connection attempt is made to a host that's not allowed here, the browser will emulate a 400 error

There are others, but these are the ones you're most likely to need.

3. How can I use multiple directives?

You define all your directives inside one meta-tag by terminating them with a semicolon (;):

content="default-src 'self' https://example.com/js/; style-src 'self'"

4. How can I handle ports?

Everything but the default ports needs to be allowed explicitly by adding the port number or an asterisk after the allowed domain:

content="default-src 'self' https://ajax.googleapis.com http://example.com:123/free/stuff/"

The above would result in:

https://ajax.googleapis.com:123
                           ^^^^ Not ok, wrong port

https://ajax.googleapis.com - OK

http://example.com/free/stuff/file.js
                 ^^ Not ok, only the port 123 is allowed

http://example.com:123/free/stuff/file.js - OK

As I mentioned, you can also use an asterisk to explicitly allow all ports:

content="default-src example.com:*"

5. How can I handle different protocols?

By default, only standard protocols are allowed. For example to allow WebSockets ws:// you will have to allow it explicitly:

content="default-src 'self'; connect-src ws:; style-src 'self'"
                                         ^^^ web Sockets are now allowed on all domains and ports.

6. How can I allow the file protocol file://?

If you'll try to define it as such it won’t work. Instead, you'll allow it with the filesystem parameter:

content="default-src filesystem"

7. How can I use inline scripts and style definitions?

Unless explicitly allowed, you can't use inline style definitions, code inside <script> tags or in tag properties like onclick. You allow them like so:

content="script-src 'unsafe-inline'; style-src 'unsafe-inline'"

You'll also have to explicitly allow inline, base64 encoded images:

content="img-src data:"

8. How can I allow eval()?

I'm sure many people would say that you don't, since 'eval is evil' and the most likely cause for the impending end of the world. Those people would be wrong. Sure, you can definitely punch major holes into your site's security with eval, but it has perfectly valid use cases. You just have to be smart about using it. You allow it like so:

content="script-src 'unsafe-eval'"

9. What exactly does 'self' mean?

You might take 'self' to mean localhost, local filesystem, or anything on the same host. It doesn't mean any of those. It means sources that have the same scheme (protocol), same host, and same port as the file the content policy is defined in. Serving your site over HTTP? No https for you then, unless you define it explicitly.

I've used 'self' in most examples as it usually makes sense to include it, but it's by no means mandatory. Leave it out if you don't need it.

But hang on a minute! Can't I just use content="default-src *" and be done with it?

No. In addition to the obvious security vulnerabilities, this also won’t work as you'd expect. Even though some docs claim it allows anything, that's not true. It doesn't allow inlining or evals, so to really, really make your site extra vulnerable, you would use this:

content="default-src * 'unsafe-inline' 'unsafe-eval'"

... but I trust you won’t.

I tried most of the suggestions, and none of them worked. I didn't get a chance to try /resetuserdata. Finally I reinstalled the plugin and uninstalled it again, and the windows went away.

While it may or may not work in your situation, I have found it useful to generate a public / private key using Putty's Pageant.

If you are also working with bitbucket (.org) it should give you the ability to provide a public key to your user account and then commands that reach out to the repository will be secured automatically.

If Pageant doesn't start up for you upon a reboot, you can add a shortcut to Pageant to your Windows "Start menu" and the shortcut may need to have a 'properties' populated with the location of your private (.ppk) file.

With this in place Mercurial and your local repositories will need to be set up to push/pull using the SSH format.

Here are some detailed instructions on Atlassian's site for Windows OR Mac/Linux.

You don't have to take my word for it and there are no doubt other ways to do it. Perhaps these steps described here are more for you:

1. Start PuttyGen from Start -> PuTTY-> PuttyGen
2. Generate a new key and save it as a .ppk file without a passphrase
3. Use Putty to login to the server you want to connect to
4. Append the Public Key text from PuttyGen to the text of ~/.ssh/authorized_keys
5. Create a shortcut to your .ppk file from Start -> Putty to Start -> Startup
6. Select the .ppk shortcut from the Startup menu (this will happen automatically at every startup)
7. See the Pageant icon in the system tray? Right-click it and select “New session”
8. Enter username@hostname in the “Host name” field
9. You will now log in automatically.

I've added some usability to the function from the answer by @Octopus, for debugging purposes.

void MatType( Mat inputMat )
{
    int inttype = inputMat.type();

    string r, a;
    uchar depth = inttype & CV_MAT_DEPTH_MASK;
    uchar chans = 1 + (inttype >> CV_CN_SHIFT);
    switch ( depth ) {
        case CV_8U:  r = "8U";   a = "Mat.at<uchar>(y,x)"; break;  
        case CV_8S:  r = "8S";   a = "Mat.at<schar>(y,x)"; break;  
        case CV_16U: r = "16U";  a = "Mat.at<ushort>(y,x)"; break; 
        case CV_16S: r = "16S";  a = "Mat.at<short>(y,x)"; break; 
        case CV_32S: r = "32S";  a = "Mat.at<int>(y,x)"; break; 
        case CV_32F: r = "32F";  a = "Mat.at<float>(y,x)"; break; 
        case CV_64F: r = "64F";  a = "Mat.at<double>(y,x)"; break; 
        default:     r = "User"; a = "Mat.at<UKNOWN>(y,x)"; break; 
    }   
    r += "C";
    r += (chans+'0');
    cout << "Mat is of type " << r << " and should be accessed with " << a << endl;

}

x86 is a 32 bit instruction set, x86_64 is a 64 bit instruction set... the difference is simple architecture. in case of windows os you better use the x86/32bit version for compatibility issues. in case of Linux you will not be able to use a 64 bit s/w if the os does not have the long mode flag.

Whatever I recommend if you have a windows 7 32 bit OS then go for 32bit or x86 binaries and as for Ubuntu 12.04 use command uname -a or grep lm /proc/cpuinfo (grep lm /proc/cpuinfo does not return value for 32 bit as 32 bit os does not has the cpuinfo flag) to know the architecture OS your OS then use the binaries according to your OS.

** Note. Remember you can always install 64 bit os in 32 bit system as long as it supports enhanced 64 bit.. 64 bit os works better some times for multi purpose work and also supports more ram than 32bits. also you can install 32bit s/w in 64 bit os..

** OS = Operating system.

I ended up here when searching for ”rxjs download file using post”.

This was my final product. It uses the file name and type given in the server response.

import { ajax, AjaxResponse } from 'rxjs/ajax';
import { map } from 'rxjs/operators';

downloadPost(url: string, data: any) {
    return ajax({
        url: url,
        method: 'POST',
        responseType: 'blob',
        body: data,
        headers: {
            'Content-Type': 'application/json',
            'Accept': 'text/plain, */*',
            'Cache-Control': 'no-cache',
        }
    }).pipe(
        map(handleDownloadSuccess),
    );
}


handleDownloadSuccess(response: AjaxResponse) {
    const downloadLink = document.createElement('a');
    downloadLink.href = window.URL.createObjectURL(response.response);

    const disposition = response.xhr.getResponseHeader('Content-Disposition');
    if (disposition) {
        const filenameRegex = /filename[^;=\n]*=((['"]).*?\2|[^;\n]*)/;
        const matches = filenameRegex.exec(disposition);
        if (matches != null && matches[1]) {
            const filename = matches[1].replace(/['"]/g, '');
            downloadLink.setAttribute('download', filename);
        }
    }

    document.body.appendChild(downloadLink);
    downloadLink.click();
    document.body.removeChild(downloadLink);
}

Assuming your byte1 is a byte(8bits), When you do a bitwise AND of a byte with 0xFF, you are getting the same byte.

So byte1 is the same as byte1 & 0xFF

Say byte1 is 01001101 , then byte1 & 0xFF = 01001101 & 11111111 = 01001101 = byte1

If byte1 is of some other type say integer of 4 bytes, bitwise AND with 0xFF leaves you with least significant byte(8 bits) of the byte1.

To avoid duplicate rows for some columns, use user_type_id instead of system_type_id.

SELECT 
    c.name 'Column Name',
    t.Name 'Data type',
    c.max_length 'Max Length',
    c.precision ,
    c.scale ,
    c.is_nullable,
    ISNULL(i.is_primary_key, 0) 'Primary Key'
FROM    
    sys.columns c
INNER JOIN 
    sys.types t ON c.user_type_id = t.user_type_id
LEFT OUTER JOIN 
    sys.index_columns ic ON ic.object_id = c.object_id AND ic.column_id = c.column_id
LEFT OUTER JOIN 
    sys.indexes i ON ic.object_id = i.object_id AND ic.index_id = i.index_id
WHERE
    c.object_id = OBJECT_ID('YourTableName')

Just replace YourTableName with your actual table name - works for SQL Server 2005 and up.

In case you are using schemas, replace YourTableName by YourSchemaName.YourTableName where YourSchemaName is the actual schema name and YourTableName is the actual table name.

First of all, this line

<img src="http://soulsnatcher.bplaced.net/LDRYh.jpg" alt="unfinished bingo card" />.click()

You're mixing HTML and JavaScript. It doesn't work like that. Get rid of the .click() there.

If you read the JavaScript you've got there, document.getElementById('foo') it's looking for an HTML element with an ID of foo. You don't have one. Give your image that ID:

<img id="foo" src="http://soulsnatcher.bplaced.net/LDRYh.jpg" alt="unfinished bingo card" />

Alternatively, you could throw the JS in a function and put an onclick in your HTML:

<img src="http://soulsnatcher.bplaced.net/LDRYh.jpg" alt="unfinished bingo card" onclick="myfunction()" />

I suggest you do some reading up on JavaScript and HTML though.

The others are right about needing to move the <img> above the JS click binding too.

What you can do is select everything into a new instance of Course, and afterwards convert them to a List.

var qry = from a in obj.tbCourses
                     select new Course() {
                         Course.Property = a.Property
                         ...
                     };

qry.toList<Course>();

<div class="row">

  <div class="col-sm-6">
    <div class="card">
        Content one
    </div>
  </div>

  <div class="col-sm-6">
    <div class="card">
        Content two
    </div>
  </div>

</div>

read from assets html file

ViewGroup webGroup;
  String content = readContent("content/ganji.html");

        final WebView webView = new WebView(this);
        webView.loadDataWithBaseURL(null, content, "text/html", "UTF-8", null);

        webGroup.addView(webView);

This worked for me well :

 public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage primaryStage) throws IOException {

        FXMLLoader loader = new FXMLLoader(getClass().getResource("/fxml/TestDataGenerator.fxml"));
        loader.setClassLoader(getClass().getClassLoader());
        Parent root = loader.load();
        primaryStage.setScene(new Scene(root));
        primaryStage.show();
    }

The properties on the style object are only the styles applied directly to the element (e.g., via a style attribute or in code). So .style.marginTop will only have something in it if you have something specifically assigned to that element (not assigned via a style sheet, etc.).

To get the current calculated style of the object, you use either the currentStyle property (Microsoft) or the getComputedStyle function (pretty much everyone else).

Example:

var p = document.getElementById("target");
var style = p.currentStyle || window.getComputedStyle(p);

display("Current marginTop: " + style.marginTop);

Fair warning: What you get back may not be in pixels. For instance, if I run the above on a p element in IE9, I get back "1em".

How do I remove unwanted parts from strings in a column?

6 years after the original question was posted, pandas now has a good number of "vectorised" string functions that can succinctly perform these string manipulation operations.

This answer will explore some of these string functions, suggest faster alternatives, and go into a timings comparison at the end.

.str.replace

Specify the substring/pattern to match, and the substring to replace it with.

If you need the result converted to an integer, you can use Series.astype,

df['result'] = df['result'].str.replace(r'\D', '').astype(int)

df.dtypes
time      object
result     int64
dtype: object

If you don't want to modify df in-place, use DataFrame.assign:

df2 = df.assign(result=df['result'].str.replace(r'\D', ''))
df
# Unchanged

.str.extract

Useful for extracting the substring(s) you want to keep.

df['result'] = df['result'].str.extract(r'(\d+)', expand=False)
df

    time result
1  09:00     52
2  10:00     62
3  11:00     44
4  12:00     30
5  13:00    110

With extract, it is necessary to specify at least one capture group. expand=False will return a Series with the captured items from the first capture group.

.str.split and .str.get

Splitting works assuming all your strings follow this consistent structure.

# df['result'] = df['result'].str.split(r'\D').str[1]
df['result'] = df['result'].str.split(r'\D').str.get(1)
df

    time result
1  09:00     52
2  10:00     62
3  11:00     44
4  12:00     30
5  13:00    110

Do not recommend if you are looking for a general solution.

If you are satisfied with the succinct and readable str accessor-based solutions above, you can stop here. However, if you are interested in faster, more performant alternatives, keep reading.

Optimizing: List Comprehensions

In some circumstances, list comprehensions should be favoured over pandas string functions. The reason is because string functions are inherently hard to vectorize (in the true sense of the word), so most string and regex functions are only wrappers around loops with more overhead.

My write-up, Are for-loops in pandas really bad? When should I care?, goes into greater detail.

The str.replace option can be re-written using re.sub

import re

# Pre-compile your regex pattern for more performance.
p = re.compile(r'\D')
df['result'] = [p.sub('', x) for x in df['result']]
df

    time result
1  09:00     52
2  10:00     62
3  11:00     44
4  12:00     30
5  13:00    110

The str.extract example can be re-written using a list comprehension with re.search,

p = re.compile(r'\d+')
df['result'] = [p.search(x)[0] for x in df['result']]
df

    time result
1  09:00     52
2  10:00     62
3  11:00     44
4  12:00     30
5  13:00    110

If NaNs or no-matches are a possibility, you will need to re-write the above to include some error checking. I do this using a function.

def try_extract(pattern, string):
    try:
        m = pattern.search(string)
        return m.group(0)
    except (TypeError, ValueError, AttributeError):
        return np.nan

p = re.compile(r'\d+')
df['result'] = [try_extract(p, x) for x in df['result']]
df

    time result
1  09:00     52
2  10:00     62
3  11:00     44
4  12:00     30
5  13:00    110

We can also re-write @eumiro's and @MonkeyButter's answers using list comprehensions:

df['result'] = [x.lstrip('+-').rstrip('aAbBcC') for x in df['result']]

And,

df['result'] = [x[1:-1] for x in df['result']]

Same rules for handling NaNs, etc, apply.

Performance Comparison

Graphs generated using perfplot. Full code listing, for your reference. The relevant functions are listed below.

Some of these comparisons are unfair because they take advantage of the structure of OP's data, but take from it what you will. One thing to note is that every list comprehension function is either faster or comparable than its equivalent pandas variant.

Functions

def eumiro(df):
    return df.assign(
        result=df['result'].map(lambda x: x.lstrip('+-').rstrip('aAbBcC')))

def coder375(df):
    return df.assign(
        result=df['result'].replace(r'\D', r'', regex=True))

    return df.assign(result=df['result'].map(lambda x: x[1:-1]))

git log -p will generate the a patch (the diff) for every commit selected. For a single file, use git log --follow -p $file.

If you're looking for a particular change, use git bisect to find the change in log(n) views by splitting the number of commits in half until you find where what you're looking for changed.

Also consider looking back in history using git blame to follow changes to the line in question if you know what that is. This command shows the most recent revision to affect a certain line. You may have to go back a few versions to find the first change where something was introduced if somebody has tweaked it over time, but that could give you a good start.

Finally, gitk as a GUI does show me the patch immediately for any commit I click on.

Example :

Handling categorical features scikit-learn expects all features to be numeric. So how do we include a categorical feature in our model?

Ordered categories: transform them to sensible numeric values (example: small=1, medium=2, large=3) Unordered categories: use dummy encoding (0/1) What are the categorical features in our dataset?

Ordered categories: weather (already encoded with sensible numeric values) Unordered categories: season (needs dummy encoding), holiday (already dummy encoded), workingday (already dummy encoded) For season, we can't simply leave the encoding as 1 = spring, 2 = summer, 3 = fall, and 4 = winter, because that would imply an ordered relationship. Instead, we create multiple dummy variables:

# An utility function to create dummy variable
`def create_dummies( df, colname ):
col_dummies = pd.get_dummies(df[colname], prefix=colname)
col_dummies.drop(col_dummies.columns[0], axis=1, inplace=True)
df = pd.concat([df, col_dummies], axis=1)
df.drop( colname, axis = 1, inplace = True )
return df`

Just connect the device to the PC with a USB cable, then copy the .apk file to the device. On the device, touch the APK file in the file explorer to install it.

You could also offer the .apk on your website. People can download it, then touch it to install.

I didn't dig in much into this but because you used fill=cond in ggplot(),

 + labs(color='NEW LEGEND TITLE') 

might not have worked. However it you replace color by fill, it works!

+ labs(fill='NEW LEGEND TITLE') 

This worked for me in ggplot2_2.1.0

AFAIK JSON.Net does not provide functionality for reading from a URL. So you need to do this in two steps:

using (var webClient = new System.Net.WebClient()) {
    var json = webClient.DownloadString(URL);
    // Now parse with JSON.Net
}

Two things occur to me.

First, are you sure you mean ManyToOne for address? That means multiple people will have the same address. If it's edited for one of them, it'll be edited for all of them. Is that your intent? 99% of the time addresses are "private" (in the sense that they belong to only one person).

Secondly, do you have any other eager relationships on the Person entity? If I recall correctly, Hibernate can only handle one eager relationship on an entity but that is possibly outdated information.

I say that because your understanding of how this should work is essentially correct from where I'm sitting.

I had the same problem and solved with '%' operator:

select 12.54 % 1;

1. I firstly added one off static table with ALL possibilities of my wildcard results (this company has a 4 character nvarchar code as their localities and they wildcard their locals) i.e. they may have 456? which would give them 456[1] to 456[Z] i.e 0-9 & a-z

2. I had to write a script to pull the current user (declare them) and pull the masks for the declared user.

3. Create some temporary tables just basic ones to rank the row numbers for this current user

4. loop through each result (YOUR Or this Or that etc...)

5. Insert into the test Table.

Here is the script I used:

Drop Table #UserMasks 
Drop Table #TESTUserMasks 

Create Table #TESTUserMasks (
    [User] [Int] NOT NULL,
    [Mask] [Nvarchar](10) NOT NULL)

Create Table #UserMasks (
    [RN] [Int] NOT NULL,
    [Mask] [Nvarchar](10) NOT NULL)

DECLARE @User INT
SET @User = 74054

Insert Into #UserMasks 
select ROW_NUMBER() OVER ( PARTITION BY ProntoUserID ORDER BY Id DESC) AS RN,
       REPLACE(mask,'?','') Mask
from dbo.Access_Masks 
where prontouserid = @User

DECLARE @TopFlag INT
SET @TopFlag = 1

WHILE (@TopFlag <=(select COUNT(*) from #UserMasks))
BEGIN
    Insert Into #TestUserMasks 
    select (@User),Code from dbo.MaskArrayLookupTable 
    where code like (select Mask + '%' from #UserMasks Where RN = @TopFlag)

    SET @TopFlag = @TopFlag + 1
END
GO

select * from #TESTUserMasks

You should try it like this:

var result =
        from priceLog in PriceLogList
        group priceLog by priceLog.LogDateTime.ToString("MMM yyyy") into dateGroup
        select new {
            LogDateTime = dateGroup.Key,
            AvgPrice = dateGroup.Average(priceLog => priceLog.Price)
        };

I had the same problem (different web app though) with the error message and it turned out to be the MIME-Type for .js files was text/x-js instead of application/javascript due to a duplicate entry in mime.types on the server that was responsible for serving the js files. It seems that this is happening if the header X-Content-Type-Options: nosniff is set, which makes Firefox (and Chrome) block the content of the js files.

This is an easy and quick solution when the string value is proper with the comma(,).

But if the string is with the last character with the comma, Which makes a blank array element, and this is also removed extra spaces around it.

"123,234,345,"

So I suggest using push()

var arr = [], str="123,234,345,"
str.split(",").map(function(item){
    if(item.trim()!=''){arr.push(item.trim())}
})

You'll want to use a udf as below

from pyspark.sql.types import IntegerType
from pyspark.sql.functions import udf

def func(fruit1, fruit2):
    if fruit1 == None or fruit2 == None:
        return 3
    if fruit1 == fruit2:
        return 1
    return 0

func_udf = udf(func, IntegerType())
df = df.withColumn('new_column',func_udf(df['fruit1'], df['fruit2']))

using System.IO; //add this namespace also 

string[] filePaths = Directory.GetFiles(@"c:\Maps\", "*.txt",
                                         SearchOption.TopDirectoryOnly);

I had this same issue and wondered why it didn't happen with a bitbucket repo that was cloned with https. Looking into it a bit I found that the config for the BB repo had a URL that included my username. So I manually edited the config for my GH repo like so and voila, no more username prompt. I'm on Windows.

Edit your_repo_dir/.git/config (remember: .git folder is hidden)

Change:

https://github.com/WEMP/project-slideshow.git

to:

https://*username*@github.com/WEMP/project-slideshow.git

Save the file. Do a git pull to test it.

The proper way to do this is probably by using git bash commands to edit the setting, but editing the file directly didn't seem to be a problem.

You can try to do like this:

var daysPassed = (DateTime.UtcNow - expiryDate).Days;
if (daysPassed > 30)
{ 
    // ...
}

if you have a context, i mean inside;

public void onReceive(Context context, Intent intent){

}

you can use this code to get resources:

context.getResources().getString(R.string.app_name);

you can try

scanf("%c%*c", &ch1);

where %*c accepts and ignores the newline

one more method instead of fflush(stdin) which invokes undefined behaviour you can write

while((getchar())!='\n');

don't forget the semicolon after while loop

Seems like Firebug or whatever Debugger you are using, is not initialized properly. Are you sure Firebug is fully initialized when you try to access the console.log()-method? Check the Console-Tab (if it's set to activated).

Another possibility could be, that you overwrite the console-Object yourself anywhere in the code.

On Mavericks I install it from the node pkg (from nodejs site) and I uninstall it so I can re-install using brew. I only run 4 commands in the terminal:

1. sudo rm -rf /usr/local/lib/node_modules/npm/
2. brew uninstall node
3. brew doctor
4. brew cleanup --prune-prefix

If there is still a node installation, repeat step 2. After all is ok, I install using brew install node

It tells the compiler that any variable marked by it must be treated in a special way when it is used inside a block. Normally, variables and their contents that are also used in blocks are copied, thus any modification done to these variables don't show outside the block. When they are marked with __block, the modifications done inside the block are also visible outside of it.

For an example and more info, see The __block Storage Type in Apple's Blocks Programming Topics.

The important example is this one:

extern NSInteger CounterGlobal;
static NSInteger CounterStatic;

{
    NSInteger localCounter = 42;
    __block char localCharacter;

    void (^aBlock)(void) = ^(void) {
        ++CounterGlobal;
        ++CounterStatic;
        CounterGlobal = localCounter; // localCounter fixed at block creation
        localCharacter = 'a'; // sets localCharacter in enclosing scope
    };

    ++localCounter; // unseen by the block
    localCharacter = 'b';

    aBlock(); // execute the block
    // localCharacter now 'a'
}

In this example, both localCounter and localCharacter are modified before the block is called. However, inside the block, only the modification to localCharacter would be visible, thanks to the __block keyword. Conversely, the block can modify localCharacter and this modification is visible outside of the block.

// For MSIE:
el.removeNode(false);

// Old js, w/o loops, using DocumentFragment:
function replaceWithContents (el) {
  if (el.parentElement) {
    if (el.childNodes.length) {
      var range = document.createRange();
      range.selectNodeContents(el);
      el.parentNode.replaceChild(range.extractContents(), el);
    } else {
      el.parentNode.removeChild(el);
    }
  }
}

// Modern es:
const replaceWithContents = (el) => {
  el.replaceWith(...el.childNodes);
};

// or just:
el.replaceWith(...el.childNodes);

// Today (2018) destructuring assignment works a little slower
// Modern es, using DocumentFragment.
// It may be faster than using ...rest
const replaceWithContents = (el) => {
  if (el.parentElement) {
    if (el.childNodes.length) {
      const range = document.createRange();
      range.selectNodeContents(el);

};

On cpanel -> software and services -> Select PHP Version.

Choose a PHP version which not the native one (I recommend php 5.6 or last one) and you will have / see a new link "Switch To PHP Settings", click it, in PHP Settings you can set upload_max_filesize in last line , clicking on value ( default is 2M ) , and you got a dropbox with values that you can set to upload_max_filesize, and click save .

If you use :active selector in combination with :hover you can achieve this according to w3schools as long as the :active selector is called after the :hover selector.

 .info-slide:hover, .info-slide:active{

 }

Complete answer (.Net Core 3.1)

Most answers here are correct but taken a bit out of context, so I will provide a full-fledged answer which works for Asp.Net Core 3.1. For completeness' sake:

[Route("health")]
[ApiController]
public class HealthController : Controller
{
    [HttpGet("some_health_url")]
    public ActionResult SomeHealthMethod() {}
}

[Route("v2")]
[ApiController]
public class V2Controller : Controller
{
    [HttpGet("some_url")]
    public ActionResult SomeV2Method()
    {
        return RedirectToAction("SomeHealthMethod", "Health"); // omit "Controller"
    }
}

If you try to use any of the url-specific strings, e.g. "some_health_url", it will not work!

Go to file \phpMyAdmin\config.inc.php at the very bottom, change the hosting details such as host, username, password etc.

The sys.maxint constant was removed, since there is no longer a limit to the value of integers. However, sys.maxsize can be used as an integer larger than any practical list or string index. It conforms to the implementation’s “natural” integer size and is typically the same as sys.maxint in previous releases on the same platform (assuming the same build options).

This question remains valid today, however the technology has changed. The old Urchin tracker is deprecated and obsolete. The new asynchronous Google Analytics tracking code uses slightly different code to achieve the same results.

Google Analytics Classic - Asynchronous Syntax - ga.js

The current syntax for setting the tracking domain to none on google analytics looks like this:

_gaq.push(['_setDomainName', 'none']);

Google analytics will then fire off the _utm.gif tracker request on localhost. You can verify this by opening the developer tools in your favorite browser and watching the network requests during page load. If it is working you will see a request for _utm.gif in the network requests list.

Google released a new version of analytics called "Universal Analytics" (late 2012 or early 2013). As I write, this the program is still in BETA so the above code is still recommended for most users with existing installations of Google Analytics.

However, for new developments using the new analytics.js code, the Google Analytics, Advanced Configuration - Web Tracking Documentation shows that we can test Universal Analytics on localhost with this new code:

ga('create', 'UA-XXXX-Y', {
  'cookieDomain': 'none'
});

Check out the linked documentation for more details on advanced configuration of Universal Analytics.

Update 2019

Both Global Site Tag - gtag.js and Universal Analytics - analytics.js will detect localhost automatically. You do not need to make any change to the configuration.

If gtag.js detects that you're running a server locally (e.g. localhost), it automatically sets the cookie_domain to 'none'.

Aloha from 2018. Unfortunately, I don't have anything cool or futuristic to share with you.

I did however want to point out to those who have commented that the jQuery load() method isn't working in the present are probably trying to use the method with local files without running a local web server. Doing so will throw the above mentioned "cross origin" error, which specifies that cross origin requests such as that made by the load method are only supported for protocol schemes like http, data, or https. (I'm assuming that you're not making an actual cross-origin request, i.e the header.html file is actually on the same domain as the page you're requesting it from)

So, if the accepted answer above isn't working for you, please make sure you're running a web server. The quickest and simplest way to do that if you're in a rush (and using a Mac, which has Python pre-installed) would be to spin up a simple Python http server. You can see how easy it is to do that here.

I hope this helps!

This is another option, using jQuery and getting only tbody rows (with the data) and desconsidering thead/tfoot.

$("#tableId > tbody > tr").length

console.log($("#myTableId > tbody > tr").length);

This will gives you basic idea

    String str="";
    String str1="";
    Scanner S=new Scanner(System.in);
    System.out.println("Enter the string");
    str=S.nextLine();
    int length=str.length();
    for(int i=0;i<length;i++)
    {
        str1=str.substring(1, length-1);
    }
    System.out.println(str1);

My formal solution:

/**
 * Decodes a hexadecimally encoded binary string.
 * <p>
 * Note that this function does <em>NOT</em> convert a hexadecimal number to a
 * binary number.
 *
 * @param hex Hexadecimal representation of data.
 * @return The byte[] representation of the given data.
 * @throws NumberFormatException If the hexadecimal input string is of odd
 * length or invalid hexadecimal string.
 */
public static byte[] hex2bin(String hex) throws NumberFormatException {
    if (hex.length() % 2 > 0) {
        throw new NumberFormatException("Hexadecimal input string must have an even length.");
    }
    byte[] r = new byte[hex.length() / 2];
    for (int i = hex.length(); i > 0;) {
        r[i / 2 - 1] = (byte) (digit(hex.charAt(--i)) | (digit(hex.charAt(--i)) << 4));
    }
    return r;
}

private static int digit(char ch) {
    int r = Character.digit(ch, 16);
    if (r < 0) {
        throw new NumberFormatException("Invalid hexadecimal string: " + ch);
    }
    return r;
}

Is like the PHP hex2bin() Function but in Java style.

Example:

String data = new String(hex2bin("6578616d706c65206865782064617461"));
// data value: "example hex data"

Using Windows Command Prompt:

rmdir /s /q folder

Using Powershell:

powershell -Command "Remove-Item -LiteralPath 'folder' -Force -Recurse"

Note that in more cases del and rmdir wil leave you with leftover files, where Powershell manages to delete the files.

You can use Url.Content which works for all links as it translates the tilde ~ to the root uri.

<a href="@Url.Action("Edit", new { id=MyId })">
    <img src="@Url.Content("~/Content/Images/Image.bmp")", alt="Edit" />
</a>

I just went through the same problem. And found out once you have a syntax or any type of error in you javascript, the whole file don't get loaded so you cannot use any of the other functions at all.

Just put your data into an Object like this:

var myObject = new Object();
myObject.name = "John";
myObject.age = 12;
myObject.pets = ["cat", "dog"];

Afterwards stringify it via:

var myString = JSON.stringify(myObject);

You don't need jQuery for this. It's pure JS.

Thanks to @IanRoberts, I had to use the normalize-space function on my nodes to check if they were empty.

<xsl:if test="((node/ABC!='') and (normalize-space(node/DEF)='') and (normalize-space(node/GHI)=''))">
  This worked perfectly fine.
</xsl:if>

MySQL added this utf8mb4 code after 5.5.3, Mb4 is the most bytes 4 meaning, specifically designed to be compatible with four-byte Unicode. Fortunately, UTF8MB4 is a superset of UTF8, except that there is no need to convert the encoding to UTF8MB4. Of course, in order to save space, the general use of UTF8 is enough.

The original UTF-8 format uses one to six bytes and can encode 31 characters maximum. The latest UTF-8 specification uses only one to four bytes and can encode up to 21 bits, just to represent all 17 Unicode planes. UTF8 is a character set in Mysql that supports only a maximum of three bytes of UTF-8 characters, which is the basic multi-text plane in Unicode.

To save 4-byte-long UTF-8 characters in Mysql, you need to use the UTF8MB4 character set, but only 5.5. After 3 versions are supported (View version: Select version ();). I think that in order to get better compatibility, you should always use UTF8MB4 instead of UTF8. For char type data, UTF8MB4 consumes more space and, according to Mysql's official recommendation, uses VARCHAR instead of char.

In MariaDB utf8mb4 as the default CHARSET when it not set explicitly in the server config, hence COLLATE utf8mb4_unicode_ci is used.

Refer MariaDB CHARSET & COLLATE Click

CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;

It's not about a plugin. It's about prompt tricks in the shell.

For a cool setup in bash, check out the dotfiles project of this guy:

https://github.com/mathiasbynens/dotfiles

To get a fancy prompt, include the .bash_prompt in your ~/.bash_profile or ~/.bashrc.

To get the exact same prompt as in your question, change the export PS1 line at the end of .bash_prompt like this:

export PS1="\[${BOLD}${MAGENTA}\]\u\[$WHITE\]@\[$ORANGE\]\h\[$WHITE\]: [\[$GREEN\]\w\[$WHITE\]\$([[ -n \$(git branch 2> /dev/null) ]] && echo \" - \")\[$PURPLE\]\$(parse_git_branch)\[$WHITE\]] \$ \[$RESET\]"

I ended up using all the .bash* files from this repository about a month ago, and it's been really useful for me.

For Git, there are extra goodies in .gitconfig.

And since you're a mac user, there are even more goodies in .osx.

So KEY is an INDEX ;)

Take a look at WordUtils in the Apache Commons lang library:

Specifically, the capitalizeFully(String str, char[] delimiters) method should do the job:

String blah = "LORD_OF_THE_RINGS";
assertEquals("LordOfTheRings", WordUtils.capitalizeFully(blah, new char[]{'_'}).replaceAll("_", ""));

Green bar!

Both on Windows and POSIX systems, named-pipes provide a way for inter-process communication to occur among processes running on the same machine. What named pipes give you is a way to send your data without having the performance penalty of involving the network stack.

Just like you have a server listening to a IP address/port for incoming requests, a server can also set up a named pipe which can listen for requests. In either cases, the client process (or the DB access library) must know the specific address (or pipe name) to send the request. Often, a commonly used standard default exists (much like port 80 for HTTP, SQL server uses port 1433 in TCP/IP; \\.\pipe\sql\query for a named pipe).

By setting up additional named pipes, you can have multiple DB servers running, each with its own request listeners.

The advantage of named pipes is that it is usually much faster, and frees up network stack resources.

-- BTW, in the Windows world, you can also have named pipes to remote machines -- but in that case, the named pipe is transported over TCP/IP, so you will lose performance. Use named pipes for local machine communication.

Practical example Using Jquery for a dropdown menu ! On mouse over on #IconLoggedinUxExternal shows div#ExternalMenuLogin and set time out to hide the div#ExternalMenuLogin

On mouse over on div#ExternalMenuLogin it cancels the timeout. On mouse out on div#ExternalMenuLogin it sets the timeout.

The point here is always to invoke clearTimeout before set the timeout, as so, avoiding double calls

var ExternalMenuLoginTO;
$('#IconLoggedinUxExternal').on('mouseover mouseenter', function () {

    clearTimeout( ExternalMenuLoginTO )
    $("#ExternalMenuLogin").show()
});

$('#IconLoggedinUxExternal').on('mouseleave mouseout', function () {

    clearTimeout( ExternalMenuLoginTO )    
    ExternalMenuLoginTO = setTimeout(
        function () {

            $("#ExternalMenuLogin").hide()

        }
        ,1000
    );
    $("#ExternalMenuLogin").show()
});

$('#ExternalMenuLogin').on('mouseover mouseenter', function () {

    clearTimeout( ExternalMenuLoginTO )
});
$('#ExternalMenuLogin').on('mouseleave mouseout', function () {

    clearTimeout( ExternalMenuLoginTO )
    ExternalMenuLoginTO = setTimeout(
        function () {

            $("#ExternalMenuLogin").hide()

        }
        ,500
    );
});

You can try changing it to this:

If myTableData.Rows.Count > 0 Then
  For i As Integer = 0 To myTableData.Rows.Count - 1
    ''Dim DataType() As String = myTableData.Rows(i).Item(1)
    ListBox2.Items.Add(myTableData.Rows(i)(1))
  Next
End If

Note: Your loop needs to be one less than the row count since it's a zero-based index.

You were looking for help on installations with pip. You can find it with the following command:

pip install --help

Running pip install -e /path/to/package installs the package in a way, that you can edit the package, and when a new import call looks for it, it will import the edited package code. This can be very useful for package development.

Try this:

video {
display:block;
margin:0 auto;
}

In my case adding jQuery to display the modal didn't work:

$(document).ready(function() {
    $('#myModal').modal('show');
});

Which seemed to be because the modal had attribute aria-hidden="true":

<div class="modal fade" aria-hidden="true" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">

Removing that attribute was needed as well as the jQuery above:

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">

Note that I tried changing the modal classes from modal fade to modal fade in, and that didn't work. Also, changing the classes from modal fade to modal show stopped the modal from being able to be closed.

C99 N1256 standard draft

http://www.open-std.org/JTC1/SC22/WG14/www/docs/n1256.pdf

6.5.3.4 The sizeof operator:

3 When applied to an operand that has structure or union type, the result is the total number of bytes in such an object, including internal and trailing padding.

6.7.2.1 Structure and union specifiers:

13 ... There may be unnamed padding within a structure object, but not at its beginning.

and:

15 There may be unnamed padding at the end of a structure or union.

The new C99 flexible array member feature (struct S {int is[];};) may also affect padding:

16 As a special case, the last element of a structure with more than one named member may have an incomplete array type; this is called a flexible array member. In most situations, the flexible array member is ignored. In particular, the size of the structure is as if the flexible array member were omitted except that it may have more trailing padding than the omission would imply.

Annex J Portability Issues reiterates:

The following are unspecified: ...

• The value of padding bytes when storing values in structures or unions (6.2.6.1)

C++11 N3337 standard draft

http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2012/n3337.pdf

5.3.3 Sizeof:

2 When applied to a class, the result is the number of bytes in an object of that class including any padding required for placing objects of that type in an array.

9.2 Class members:

A pointer to a standard-layout struct object, suitably converted using a reinterpret_cast, points to its initial member (or if that member is a bit-field, then to the unit in which it resides) and vice versa. [ Note: There might therefore be unnamed padding within a standard-layout struct object, but not at its beginning, as necessary to achieve appropriate alignment. — end note ]

I only know enough C++ to understand the note :-)

I feel the simplest way would be

 from matplotlib import pyplot;
 from pylab import genfromtxt;  
 mat0 = genfromtxt("data0.txt");
 mat1 = genfromtxt("data1.txt");
 pyplot.plot(mat0[:,0], mat0[:,1], label = "data0");
 pyplot.plot(mat1[:,0], mat1[:,1], label = "data1");
 pyplot.legend();
 pyplot.show();

1. label is the string that is displayed on the legend
2. you can plot as many series of data points as possible before show() to plot all of them on the same graph This is the simple way to plot simple graphs. For other options in genfromtxt go to this url.

Apache commons collections library provides a utility method for inversing the map. You can use this if you are sure that the values of myHashMap are unique

org.apache.commons.collections.MapUtils.invertMap(java.util.Map map)

Sample code

HashMap<String, Character> reversedHashMap = MapUtils.invertMap(myHashMap) 

$mylabel.text("-123456");
var string = $mylabel.text().replace('-', '');

if you have done it that way variable string now holds "123456"

you can also (i guess the better way) do this...

$mylabel.text("-123456");
$mylabel.text(function(i,v){
   return v.replace('-','');
});

Solution for FormArray controllers 

Initialize FormArray form Builder

  formInitilize() {
    this.Form = this._formBuilder.group({
      formArray: this._formBuilder.array([this.createForm()])
    });
  }

Create Form

  createForm() {
    return (this.Form = this._formBuilder.group({
      convertodecimal: ['']
    }));
  }

Set Form Values into Form Controller

  setFormvalues() {
    this.Form.setControl('formArray', this._formBuilder.array([]));
    const control = <FormArray>this.resourceBalanceForm.controls['formArray'];
    this.ListArrayValues.forEach((x) => {
      control.push(this.buildForm(x));
    });
  }

  private buildForm(x): FormGroup {
    const bindvalues= this._formBuilder.group({
      convertodecimal: x.ArrayCollection1? parseFloat(x.ArrayCollection1[0].name).toFixed(2) : '' // Option for array collection
// convertodecimal: x.number.toFixed(2)    --- option for two decimal value 
    });

    return bindvalues;
  }

How about an extension method?

Here I have a show or hide method. Using my CSS class hidden.

public static class HtmlControlExtensions
{
    public static void Hide(this HtmlControl ctrl)
    {
        if (!string.IsNullOrEmpty(ctrl.Attributes["class"]))
        {
            if (!ctrl.Attributes["class"].Contains("hidden"))
                ctrl.Attributes.Add("class", ctrl.Attributes["class"] + " hidden");
        }
        else
        {
            ctrl.Attributes.Add("class", "hidden");
        }
    }

    public static void Show(this HtmlControl ctrl)
    {
        if (!string.IsNullOrEmpty(ctrl.Attributes["class"]))
            if (ctrl.Attributes["class"].Contains("hidden"))
                ctrl.Attributes.Add("class", ctrl.Attributes["class"].Replace("hidden", ""));
    }
}

Then when you want to show or hide your control:

myUserControl.Hide();

//... some other code

myUserControl.Show();

This is simple if you only use Selenium WebDriver, and forget the usage of Selenium-RC. I'd go like this.

WebDriver driver = new FirefoxDriver();
WebElement email = driver.findElement(By.id("email"));
email.sendKeys("[email protected]");

The reason for NullPointerException however is that your variable driver has never been started, you start FirefoxDriver in a variable wb thas is never being used.

You have a truncated array representation. Let's look at a full example:

>>> a = np.zeros((2, 3, 4))
>>> a
array([[[ 0.,  0.,  0.,  0.],
        [ 0.,  0.,  0.,  0.],
        [ 0.,  0.,  0.,  0.]],

       [[ 0.,  0.,  0.,  0.],
        [ 0.,  0.,  0.,  0.],
        [ 0.,  0.,  0.,  0.]]])

Arrays in NumPy are printed as the word array followed by structure, similar to embedded Python lists. Let's create a similar list:

>>> l = [[[ 0.,  0.,  0.,  0.],
          [ 0.,  0.,  0.,  0.],
          [ 0.,  0.,  0.,  0.]],

          [[ 0.,  0.,  0.,  0.],
          [ 0.,  0.,  0.,  0.],
          [ 0.,  0.,  0.,  0.]]]

>>> l
[[[0.0, 0.0, 0.0, 0.0], [0.0, 0.0, 0.0, 0.0], [0.0, 0.0, 0.0, 0.0]], 
 [[0.0, 0.0, 0.0, 0.0], [0.0, 0.0, 0.0, 0.0], [0.0, 0.0, 0.0, 0.0]]]

The first level of this compound list l has exactly 2 elements, just as the first dimension of the array a (# of rows). Each of these elements is itself a list with 3 elements, which is equal to the second dimension of a (# of columns). Finally, the most nested lists have 4 elements each, same as the third dimension of a (depth/# of colors).

So you've got exactly the same structure (in terms of dimensions) as in Matlab, just printed in another way.

Some caveats:

1. Matlab stores data column by column ("Fortran order"), while NumPy by default stores them row by row ("C order"). This doesn't affect indexing, but may affect performance. For example, in Matlab efficient loop will be over columns (e.g. for n = 1:10 a(:, n) end), while in NumPy it's preferable to iterate over rows (e.g. for n in range(10): a[n, :] -- note n in the first position, not the last).

2. If you work with colored images in OpenCV, remember that:

   2.1. It stores images in BGR format and not RGB, like most Python libraries do.

   2.2. Most functions work on image coordinates (x, y), which are opposite to matrix coordinates (i, j).

Same origin policy has nothing to do with sending request to another url (different protocol or domain or port).

It is all about restricting access to (reading) response data from another url. So JavaScript code within a page can post to arbitrary domain or submit forms within that page to anywhere (unless the form is in an iframe with different url).

But what makes these POST requests inefficient is that these requests lack antiforgery tokens, so are ignored by the other url. Moreover, if the JavaScript tries to get that security tokens, by sending AJAX request to the victim url, it is prevented to access that data by Same Origin Policy.

A good example: here

And a good documentation from Mozilla: here

The best thing is to actually use the kernel makefile to install the module:

Here is are snippets to add to your Makefile

around the top add:

PWD=$(shell pwd)
VER=$(shell uname -r)
KERNEL_BUILD=/lib/modules/$(VER)/build
# Later if you want to package the module binary you can provide an INSTALL_ROOT
# INSTALL_ROOT=/tmp/install-root

around the end add:

install:
        $(MAKE) -C $(KERNEL_BUILD) M=$(PWD) \
           INSTALL_MOD_PATH=$(INSTALL_ROOT) modules_install

and then you can issue

    sudo make install

this will put it either in /lib/modules/$(uname -r)/extra/

or /lib/modules/$(uname -r)/misc/

and run depmod appropriately

Building off of Fabio's answer, I created two functions that will probably be useful for anyone stumbling upon this question. With these two functions, you can call insertParam() with a key and value as an argument. It will either add the URL parameter or, if a query param already exists with the same key, it will change that parameter to the new value:

//function to remove query params from a URL
function removeURLParameter(url, parameter) {
    //better to use l.search if you have a location/link object
    var urlparts= url.split('?');   
    if (urlparts.length>=2) {

        var prefix= encodeURIComponent(parameter)+'=';
        var pars= urlparts[1].split(/[&;]/g);

        //reverse iteration as may be destructive
        for (var i= pars.length; i-- > 0;) {    
            //idiom for string.startsWith
            if (pars[i].lastIndexOf(prefix, 0) !== -1) {  
                pars.splice(i, 1);
            }
        }

        url= urlparts[0] + (pars.length > 0 ? '?' + pars.join('&') : "");
        return url;
    } else {
        return url;
    }
}

//function to add/update query params
function insertParam(key, value) {
    if (history.pushState) {
        // var newurl = window.location.protocol + "//" + window.location.host + search.pathname + '?myNewUrlQuery=1';
        var currentUrlWithOutHash = window.location.origin + window.location.pathname + window.location.search;
        var hash = window.location.hash
        //remove any param for the same key
        var currentUrlWithOutHash = removeURLParameter(currentUrlWithOutHash, key);

        //figure out if we need to add the param with a ? or a &
        var queryStart;
        if(currentUrlWithOutHash.indexOf('?') !== -1){
            queryStart = '&';
        } else {
            queryStart = '?';
        }

        var newurl = currentUrlWithOutHash + queryStart + key + '=' + value + hash
        window.history.pushState({path:newurl},'',newurl);
    }
}

This error can occur when you rename files outside of XCode. To solve it you can just remove the files from your project (Right Click - Delete and "Remove Reference").

Then after you can re-import the files in your project and everything will be OK.

$str = basename($url);

You can also use "shouldReceiveTouch" method of UIGestureRecognizer

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:     (UITouch *)touch {
     UIView *view = touch.view; 
     NSLog(@"%d", view.tag); 
}    

Dont forget to set delegate of your gesture recognizer.

Assuming your "date" column is not actually a date.

Select convert(varchar(8),cast('12/24/2016' as date),112)

or

Select format(cast('12/24/2016' as date),'yyyyMMdd')

Returns

20161224

Considering Natalie's response, it seemed very good, but I had problems with a possible footer area, which could be hacked a little using clear: both.

Of course, a better solution would be to use flexbox or grid nowadays.

You can check this codepen if you want.

.section {
  width: 500px;
  margin: auto;
  overflow: hidden;
  padding: 0;
}

div {
  padding: 1rem;
}

.header {

DataRow's are nice in the way that they have their underlying table linked to them. With the underlying table you can verify that a specific row has a specific column in it.

    If DataRow.Table.Columns.Contains("column") Then
        MsgBox("YAY")
    End If

for (int i=0;i < Table.Rows.Count;i++)
{
      Var YourValue = Table.Rows[i]["ColumnName"];
}

As mentioned previously you really can't do this. You can do a modal dialog inside the window using a UI framework, or you can have a popup window, with a script that auto-closes after a timeout... each has a negative aspect. The modal window inside the browser won't create any notification if the window is minimized, and a programmatic (timer based) popup is likely to be blocked by modern browsers, and popup blockers.

Custom color for the status bar (iOS11+, Swift4+)

If you are looking for a solution how to change the status bar to your custom color, this the working solution.

let statusBarView = UIView()
view.addSubview(statusBarView)
statusBarView.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
    statusBarView.topAnchor.constraint(equalTo: view.topAnchor),
    statusBarView.leftAnchor.constraint(equalTo: view.leftAnchor),
    statusBarView.rightAnchor.constraint(equalTo: view.rightAnchor),
    statusBarView.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor)
])
statusBarView.backgroundColor = .blue

If for some reason you don't want to use the break instruction (if you think it will disrupt your reading flow next time you will read your programm, for example), you can try the following :

boolean test = true;
for (int i = 0; i < 1220 && test; i++) {
    System.out.println(i);
    if (i == 20) {
        test = false;
    }
 }

The second arg of a for loop is a boolean test. If the result of the test is true, the loop will stop. You can use more than just an simple math test if you like. Otherwise, a simple break will also do the trick, as others said :

for (int i = 0; i < 1220 ; i++) {
    System.out.println(i);
    if (i == 20) {
        break;
    }
 }

You can simply use:

ps -o args= -f -p ProcessPid

Error

push failed
fatal: unable to access
SSL certificate problem: unable to get local issuer certificate

Reason

After committing files on a local machine, the "push fail" error can occur when the local Git connection parameters are outdated (e.g. HTTP change to HTTPS).

Solution

1. Open the .git folder in the root of the local directory
2. Open the config file in a code editor or text editor (VS Code, Notepad, Textpad)
3. Replace HTTP links inside the file with the latest HTTPS or SSH link available from the web page of the appropriate Git repo (clone button)
   Examples:

   url = http://git.[host]/[group/project/repo_name]     (actual path)
   

   replace it with either

   url = ssh://git@git.[host]:/[group/project/repo_name] (new path SSH)
   url = https://git.[host]/[group/project/repo_name]    (new path HTTPS)
   

My favourite has always been gnuplot. It's very extensive, so it might be a bit too complex for your needs though. It is cross-platform and there is a C++ API.

This was the best way for me. You can retrieve all existing files (be it symbolic links or normal):

os.path.lexists(path)

Return True if path refers to an existing path. Returns True for broken symbolic links. Equivalent to exists() on platforms lacking os.lstat().

New in version 2.4.

In your case, it will produce an error. :-)

Set assigns an object reference. For all other assignments the (implicit, optional, and little-used) Let statement is correct:

Set object = New SomeObject
Set object = FunctionReturningAnObjectRef(SomeArgument)

Let i = 0
Let i = FunctionReturningAValue(SomeArgument)

' or, more commonly '

i = 0
i = FunctionReturningAValue(SomeArgument)

I am fighting the soft keyboard on the Honeywell Dolphin 70e with Android 4.0.3. I don't need the keyboard because the input comes from the builtin barcode reader through the 'scanwedge', set to generate key events.

What I found was that the trick described in the earlier answers of:

input.blur();
input.focus();

works, but only once, right at page initialization. It puts the focus in the input element without showing the soft keyboard. It does NOT work later, e.g. after a TAB character in the suffix of the barcode causes the onblur or oninput event on the input element.

To read and process lots of barcodes, you may use a different postfix than TAB (9), e.g. 8, which is not interpreted by the browser. In the input.keydown event, use e.keyCode == 8 to detect a complete barcode to be processed.

This way, you initialize the page with focus in the input element, with keyboard hidden, all barcodes go to the input element, and the focus never leaves that element. Of course, the page cannot have other input elements (like buttons), because then you will not be able to return to the barcode input element with the soft keyboard hidden.

Perhaps reloading the page after a button click may be able to hide the keyboard. So use ajax for fast processing of barcodes, and use a regular asp.net button with PostBack to process a button click and reload the page to return focus to the barcode input with the keyboard hidden.

You are looking to see if a single value is in an array. Use in_array.

However note that case is important, as are any leading or trailing spaces. Use var_dump to find out the length of the strings too, and see if they fit.

"BadRequest" is an error which usually got send by the server itself, see rfc 2616

10.4.1 400 Bad Request

The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications.

So you got a working connection to the server, but your request doesn't fit the expecet form. I don't know how you create the connection, what headers are included (if there are any) – but thats what you should checking for.

If you need more help about, explain what your code is about and what it uses to connect to the Server, so we have the big picture.

Here is a question with the same Problem – the answer was that the content-type wasnt set in the header.

From the Project Explorer, expand the project you want to hook up to a remote site (or just right click and create a new Web project that's empty if you just want to explore a remote site from there). There's a "Connections" node, right click it and select "Add New connection...". A dialog will appear, at bottom you can select the destination as Remote and then click the "New..." button. There you can set up an FTP/FTPS/SFTP connection.

That's how you set up a connection that's tied to a project, typically for upload/download/sync between it and a project.

You can also do Window > Show View > Remote. From that view, you can click the globe icon in the upper right to add connections and in this view you can just browse your remote connections.

Edit: 2013.01.15 - If your server will support it, use martinstoeckli's solution instead.

Everyone wants to make this more complicated than it is. The crypt() function does most of the work.

function blowfishCrypt($password,$cost)
{
    $chars='./ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789';
    $salt=sprintf('$2y$%02d$',$cost);
//For PHP < PHP 5.3.7 use this instead
//    $salt=sprintf('$2a$%02d$',$cost);
    //Create a 22 character salt -edit- 2013.01.15 - replaced rand with mt_rand
    mt_srand();
    for($i=0;$i<22;$i++) $salt.=$chars[mt_rand(0,63)];
    return crypt($password,$salt);
}

Example:

$hash=blowfishCrypt('password',10); //This creates the hash
$hash=blowfishCrypt('password',12); //This creates a more secure hash
if(crypt('password',$hash)==$hash){ /*ok*/ } //This checks a password

I know it should be obvious, but please don't use 'password' as your password.

The where statement gets executed before the order by. So, your desired query is saying "take the first row and then order it by t_stamp desc". And that is not what you intend.

The subquery method is the proper method for doing this in Oracle.

If you want a version that works in both servers, you can use:

select ril.*
from (select ril.*, row_number() over (order by t_stamp desc) as seqnum
      from raceway_input_labo ril
     ) ril
where seqnum = 1

The outer * will return "1" in the last column. You would need to list the columns individually to avoid this.

Short Code

public class DB {

    public static Connection c;

    public static Connection getConnection() throws Exception {
        if (c == null) {
            Class.forName("com.mysql.jdbc.Driver");
            c =DriverManager.getConnection("jdbc:mysql://localhost:3306/DATABASE", "USERNAME", "Password");
        }
        return c;
    }

    // Send data TO Database
    public static void setData(String sql) throws Exception {
        DB.getConnection().createStatement().executeUpdate(sql);
    }

    // Get Data From Database
    public static ResultSet getData(String sql) throws Exception {
        ResultSet rs = DB.getConnection().createStatement().executeQuery(sql);
        return rs;
    }
}

From http://sed.sourceforge.net/sed1line.txt: (Please don't ask me how this works ;-) )

 # delete duplicate, consecutive lines from a file (emulates "uniq").
 # First line in a set of duplicate lines is kept, rest are deleted.
 sed '$!N; /^\(.*\)\n\1$/!P; D'

 # delete duplicate, nonconsecutive lines from a file. Beware not to
 # overflow the buffer size of the hold space, or else use GNU sed.
 sed -n 'G; s/\n/&&/; /^\([ -~]*\n\).*\n\1/d; s/\n//; h; P'

Not really. Your padding is (probably) being applied to the list item, so will only affect the actual content within the list item.

Using a combination of background and padding styles can create something that looks similar e.g.

li {
  background: url(images/bullet.gif) no-repeat left top; /* <-- change `left` & `top` too for extra control */
  padding: 3px 0px 3px 10px;
  /* reset styles (optional): */
  list-style: none;
  margin: 0;
}

You might be looking to add styling to the parent list container (ul) to position your bulleted list items, this A List Apart article has a good starting reference.

FWIW, htpasswd -n username will output the result directly to stdout, and avoid touching files altogether.

I have found the answer to my question myself:)

So what I didn't understand was how the glibc could differentiate between a Segfault and a corrupted double-linked list, because according to my understanding, from perspective of glibc they should look like the same thing. Because if I implement a double-linked list inside my program, how could the glibc possibly know that this is a double-linked list, instead of any other struct? It probably can't, so thats why i was confused.

Now I've looked at malloc/malloc.c inside the glibc's code, and I see the following:

1543 /* Take a chunk off a bin list */
1544 #define unlink(P, BK, FD) {                                            \
1545   FD = P->fd;                                                          \
1546   BK = P->bk;                                                          \
1547   if (__builtin_expect (FD->bk != P || BK->fd != P, 0))                \
1548     malloc_printerr (check_action, "corrupted double-linked list", P); \
1549   else {                                                               \
1550     FD->bk = BK;                                                       \
1551     BK->fd = FD;                                                       \

So now this suddenly makes sense. The reason why glibc can know that this is a double-linked list is because the list is part of glibc itself. I've been confused because I thought glibc can somehow detect that some programming is building a double-linked list, which I wouldn't understand how that works. But if this double-linked list that it is talking about, is part of glibc itself, of course it can know it's a double-linked list.

I still don't know what has triggered this error. But at least I understand the difference between corrupted double-linked list and a Segfault, and how the glibc can know this struct is supposed to be a double-linked list:)

Using just one call to replace (regex version): var bgUrl = $('#element-id').css('background-image').replace(/url\(("|')(.+)("|')\)/gi, '$2');

puts false or true --> prints: false

puts false || true --> prints: true

Here's what I use in my code. It works like a charm!

In yourviewcontroller.h add:

@property (nonatomic) UITapGestureRecognizer *tapRecognizer;

Now in the .m file, add this to your ViewDidLoad function:

- (void)viewDidLoad {
    //Keyboard stuff
    tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(didTapAnywhere:)];
    tapRecognizer.cancelsTouchesInView = NO;
    [self.view addGestureRecognizer:tapRecognizer];
}

Also, add this function in the .m file:

- (void)handleSingleTap:(UITapGestureRecognizer *) sender
{
    [self.view endEditing:YES];
}

The EOF flag is only set after a read operation attempts to read past the end of the file. get() is returning the symbolic constant traits::eof() (which just happens to equal -1) because it reached the end of the file and could not read any more data, and only at that point will eof() be true. If you want to check for this condition, you can do something like the following:

int ch;
while ((ch = inf.get()) != EOF) {
    std::cout << static_cast<char>(ch) << "\n";
}

check the round function and how does the length argument works. It controls the behaviour of the precision of the result

You can also just Marshal.Copy the bitmap data. No intermediary memorystream etc. and a fast memory copy. This should work on both 24-bit and 32-bit bitmaps.

public static byte[] BitmapToByteArray(Bitmap bitmap)
{

    BitmapData bmpdata = null;

    try
    {
        bmpdata = bitmap.LockBits(new Rectangle(0, 0, bitmap.Width, bitmap.Height), ImageLockMode.ReadOnly, bitmap.PixelFormat);
        int numbytes = bmpdata.Stride * bitmap.Height;
        byte[] bytedata = new byte[numbytes];
        IntPtr ptr = bmpdata.Scan0;

        Marshal.Copy(ptr, bytedata, 0, numbytes);

        return bytedata;
    }
    finally
    {
        if (bmpdata != null)
            bitmap.UnlockBits(bmpdata);
    }

}

.

This can be an issue with Glide. Use this while you are trying to load to many images and some of them are very large:

Glide.load("your image path")
                       .transform(
                               new MultiTransformation<>(
                                       new CenterCrop(),
                                       new RoundedCorners(
                                               holder.imgCompanyLogo.getResources()
                                                       .getDimensionPixelSize(R.dimen._2sdp)
                                       )
                               )
                       )
                       .error(R.drawable.ic_nfs_default)
                       .into(holder.imgCompanyLogo);
           }

I fear that restarting the entire application using Process is approaching your problem in the wrong way.

An easier way is to modify the Program.cs file to restart:

    static bool restart = true; // A variable that is accessible from program
    static int restartCount = 0; // Count the number of restarts
    static int maxRestarts = 3;  // Maximum restarts before quitting the program

    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);

        while (restart && restartCount < maxRestarts)
        {
           restart = false; // if you like.. the program can set it to true again
           restartCount++;  // mark another restart,
                            // if you want to limit the number of restarts
                            // this is useful if your program is crashing on 
                            // startup and cannot close normally as it will avoid
                            // a potential infinite loop

           try {
              Application.Run(new YourMainForm());
           }
           catch {  // Application has crashed
              restart = true;
           }
        }
    }

You can work around that via a Live Template. Go to Settings -> Live Template, click the "Add"-Button (green plus on the right).

In the "Abbreviation" field, enter the string that should activate the template (e.g. @a), and in the "Template Text" area enter the string to complete (e.g. @author - My Name). Set the "Applicable context" to Java (Comments only maybe) and set a key to complete (on the right).

I tested it and it works fine, however IntelliJ seems to prefer the inbuild templates, so "@a + Tab" only completes "author". Setting the completion key to Space worked however.

To change the user name that is automatically inserted via the File Templates (when creating a class for example), can be changed by adding

-Duser.name=Your name

to the idea.exe.vmoptions or idea64.exe.vmoptions (depending on your version) in the IntelliJ/bin directory.

Restart IntelliJ

For Jackson versions < 2.0 use this annotation on the class being serialized:

@JsonSerialize(include=JsonSerialize.Inclusion.NON_NULL)

You have different choices to handle this. It seem like its taking us back to old good plain SQL days :)

Read this: http://www.javacodegeeks.com/2012/07/four-solutions-to-lazyinitializationexc_05.html

Don`t forget to use DataGrid.Columns, all columns must be inside that collection. In my project I format date a little bit differently:

<tk:DataGrid>
    <tk:DataGrid.Columns>
        <tk:DataGridTextColumn Binding="{Binding StartDate, StringFormat=\{0:dd.MM.yy HH:mm:ss\}}" />
    </tk:DataGrid.Columns>
</tk:DataGrid>

With AutoGenerateColumns you won`t be able to contol formatting as DataGird will add its own columns.

You need to properly decode the source text. Most likely the source text is in UTF-8 format, not ASCII.

Because you do not provide any context or code for your question it is not possible to give a direct answer.

I suggest you study how unicode and character encoding is done in Python:

Valentin Rocher's method works if you've extended your view, but if you're using an event listener, use this:

view.setOnTouchListener(new OnTouchListener()
{
    public boolean onTouch(View v, MotionEvent event)
    {
        Toast toast = Toast.makeText(
            getApplicationContext(), 
            "View touched", 
            Toast.LENGTH_LONG
        );
        toast.show();

        return true;
    }
});


// Obtain MotionEvent object
long downTime = SystemClock.uptimeMillis();
long eventTime = SystemClock.uptimeMillis() + 100;
float x = 0.0f;
float y = 0.0f;
// List of meta states found here: developer.android.com/reference/android/view/KeyEvent.html#getMetaState()
int metaState = 0;
MotionEvent motionEvent = MotionEvent.obtain(
    downTime, 
    eventTime, 
    MotionEvent.ACTION_UP, 
    x, 
    y, 
    metaState
);

// Dispatch touch event to view
view.dispatchTouchEvent(motionEvent);

For more on obtaining a MotionEvent object, here is an excellent answer: Android: How to create a MotionEvent?

there might be the situation your machine is managed by Puppet or so. Then changing root .profile or .bash_rc file does not work at all. Therefore you could add the following to your .profile file. After that you can use "mydo" instead of "sudo". It works perfectly for me.

function mydo() {
    echo Executing sudo with: "$1" "${@:2}"
    sudo $(which $1) "${@:2}"
}

You assign to big and small before the array is initialized, i.e., big and small assume the value of whatever is on the stack at this point. As they are just plain value types and no references, they won't assume a new value once values[0] is written to via cin >>.

Just move the assignment after your first loop and it should be fine.

Instead of

Image.open(picture.jpg)
Img.show

You should have

from PIL import Image

#...

img = Image.open('picture.jpg')
img.show()

You should probably also think about an other system to show your messages, because this way it will be a lot of manual work. Look into string substitution (using %s or .format()).

You also can use git filter-branch for that.

git filter-branch -f --msg-filter "sed 's/errror/error/'" $flawed_commit..HEAD

It's not as easy as a trivial git commit --amend, but it's especially useful, if you already have some merges after your erroneous commit message.

Note that this will try to rewrite every commit between HEAD and the flawed commit, so you should choose your msg-filter command very wisely ;-)

I have used mpdf in my project. In Codeigniter-3, putted mpdf files under application/third_party and then used in this way:

 /**
 * This function is used to display data in PDF file.
 * function is using mpdf api to generate pdf.
 * @param number $id : This is unique id of table.
 */
function generatePDF($id){
    require APPPATH . '/third_party/mpdf/vendor/autoload.php';
    //$mpdf=new mPDF();
    $mpdf = new mPDF('utf-8', 'Letter', 0, '', 0, 0, 7, 0, 0, 0);

    $checkRecords =  $this->user_model->getCheckInfo($id);      
    foreach ($checkRecords as $key => $value) {
        $data['info'] = $value;
        $filename = $this->load->view(CHEQUE_VIEWS.'index',$data,TRUE);
        $mpdf->WriteHTML($filename); 
    }

    $mpdf->Output(); //output pdf document.
    //$content = $mpdf->Output('', 'S'); //get pdf document content's as variable. 

}

If the size of the subdirectory is not particularly huge, AND you wish to stay away from the CLI, here's a quick solution to manually reset the sub-directory:

1. Switch to master branch and copy the sub-directory to be reset.
2. Now switch back to your feature branch and replace the sub-directory with the copy you just created in step 1.
3. Commit the changes.

Cheers. You just manually reset a sub-directory in your feature branch to be same as that of master branch !!

The lmplot function returns a FacetGrid instance. This object has a method called set, to which you can pass key=value pairs and they will be set on each Axes object in the grid.

Secondly, you can set only one side of an Axes limit in matplotlib by passing None for the value you want to remain as the default.

Putting these together, we have:

g = sns.lmplot('X', 'Y', df, col='Z', sharex=False, sharey=False)
g.set(ylim=(0, None))

a short summary:

track by is used in order to link your data with the DOM generation (and mainly re-generation) made by ng-repeat.

when you add track by you basically tell angular to generate a single DOM element per data object in the given collection

this could be useful when paging and filtering, or any case where objects are added or removed from ng-repeat list.

usually, without track by angular will link the DOM objects with the collection by injecting an expando property - $$hashKey - into your JavaScript objects, and will regenerate it (and re-associate a DOM object) with every change.

If your class extends JFrame then use this.setTitle(newTitle.getText());

If not and it contains a JFrame let's say named myFrame, then use myFrame.setTitle(newTitle.getText());

Now that you have posted your program, it is obvious that you need only one JTextField to get the new title. These changes will do the trick:

JTextField poolLengthText, poolWidthText, poolDepthText, poolVolumeText, hotTub,
        hotTubLengthText, hotTubWidthText, hotTubDepthText, hotTubVolumeText, temp, results,
        newTitle;

and:

    public void createOptions()
    {
        options = new JPanel();
        options.setLayout(null);
        JLabel labelOptions = new JLabel("Change Company Name:");
        labelOptions.setBounds(120, 10, 150, 20);
        options.add(labelOptions);
        newTitle = new JTextField("Some Title");
        newTitle.setBounds(80, 40, 225, 20);
        options.add(newTitle);
//        myTitle = new JTextField("My Title...");
//        myTitle.setBounds(80, 40, 225, 20);
//        myTitle.add(labelOptions);
        JButton newName = new JButton("Set New Name");
        newName.setBounds(60, 80, 150, 20);
        newName.addActionListener(this);
        options.add(newName);
        JButton Exit = new JButton("Exit");
        Exit.setBounds(250, 80, 80, 20);
        Exit.addActionListener(this);
        options.add(Exit);
    }

and:

private void New_Name()
{
    this.setTitle(newTitle.getText());
}

The ref keyword is used to pass values by reference. (This does not preclude the passed values being value-types or reference types). Output parameters specified with the out keyword are for returning values from a method.

One key difference in the code is that you must set the value of an output parameter within the method. This is not the case for ref parameters.

For more details look at http://www.blackwasp.co.uk/CSharpMethodParameters.aspx

Open the Command Prompt and Type :

cd  c:\windows\assembly\GAC_MSIL 

xcopy . C:\GacDump /s /y

This should give the dump of the entire GAC

Enjoy!

I got this error for my Linux Jenkins slave. I fixed it by changing from the node from "Known hosts file Verification Strategy" to "Non verifying Verification Strategy".

While you use .on(), it's basically a live query that you are using.

On the other hand, .ready (as in your case) is a static query. While using it, you can dynamically update data and do not have to wait for the page to load. You can simply pass on the values into your database (if required) when a particular value is entered.

The use of live queries is common in forms where we enter data (account or posts or even comments).

Integer class has static method toString() - you can use it:

int i = 1234;
String str = Integer.toString(i);

Returns a String object representing the specified integer. The argument is converted to signed decimal representation and returned as a string, exactly as if the argument and radix 10 were given as arguments to the toString(int, int) method.

Below format try if number is like

ex 1 suppose number like 10.1 if apply below format it will be come as 10.10

ex 2 suppose number like .02 if apply below format it will be come as 0.02

ex 3 suppose number like 0.2 if apply below format it will be come as 0.20

to_char(round(to_number(column_name)/10000000,2),'999999999990D99') as column_name

I wasn't able to use the 403 method because I wanted the maintenance page and page images in a sub folder on my server, so used the following approach to redirect to a 'maintenance page' for everyone but a single IP*

RewriteEngine on
RewriteCond %{REMOTE_ADDR} !**.**.**.*
RewriteRule !^maintenance/ http://www.website.co.uk/maintenance/ [R=302,L]

You have 2 methods to check whether the string is empty or not:

Let's suppose your string name is NSString *strIsEmpty.

Method 1:

if(strIsEmpty.length==0)
{
    //String is empty
}

else
{
    //String is not empty
}

Method 2:

if([strIsEmpty isEqualToString:@""])
{
    //String is empty
}

else
{
    //String is not empty
}

Choose any of the above method and get to know whether string is empty or not.

The replacement with snprintf is NOT complete!

It covers only bases: 2, 8, 10, 16, whereas itoa works for bases between 2 and 36.

Since I was searching a replacement for base 32, I guess I'll have to code my own!

sapply(yourdataframe, class)

Where yourdataframe is the name of the data frame you're using

Did you try gcc -S -fverbose-asm -O source.c then look into the generated source.s assembler file ?

The generated assembler code goes into source.s (you could override that with -o assembler-filename ); the -fverbose-asm option asks the compiler to emit some assembler comments "explaining" the generated assembler code. The -O option asks the compiler to optimize a bit (it could optimize more with -O2 or -O3).

If you want to understand what gcc is doing try passing -fdump-tree-all but be cautious: you'll get hundreds of dump files.

BTW, GCC is extensible thru plugins or with MELT (a high level domain specific language to extend GCC; which I abandoned in 2017)

You have many options. Collating some of the answers above and the accepted answer from this post you can do:
1. df[-df["column"].isin(["value"])]
2. df[~df["column"].isin(["value"])]
3. df[df["column"].isin(["value"]) == False]
4. df[np.logical_not(df["column"].isin(["value"]))]

Note: for option 4 for you'll need to import numpy as np

Update: You can also use the .query method for this too. This allows for method chaining:
5. df.query("column not in @values").
where values is a list of the values that you don't want to include.

Difference between Static methods and Instance methods

1. Instance method are methods which require an object of its class to be created before it can be called. Static methods are the methods in Java that can be called without creating an object of class.

2. Static method is declared with static keyword. Instance method is not with static keyword.

3. Static method means which will exist as a single copy for a class. But instance methods exist as multiple copies depending on the number of instances created for that class.

4. Static methods can be invoked by using class reference. Instance or non static methods are invoked by using object reference.

5. Static methods can’t access instance methods and instance variables directly. Instance method can access static variables and static methods directly.

Try to add the class for validation dynamically, when the form has been submitted or the field is invalid. Use the form name and add the 'name' attribute to the input. Example with Bootstrap:

<div class="form-group" ng-class="{'has-error': myForm.$submitted && (myForm.username.$invalid && !myForm.username.$pristine)}">
    <label class="col-sm-2 control-label" for="username">Username*</label>
    <div class="col-sm-10 col-md-9">
        <input ng-model="data.username" id="username" name="username" type="text" class="form-control input-md" required>
    </div>
</div>

It is also important, that your form has the ng-submit="" attribute:

<form name="myForm" ng-submit="checkSubmit()" novalidate>
 <!-- input fields here -->
 ....

  <button type="submit">Submit</button>
</form>

You can also add an optional function for validation to the form:

//within your controller (some extras...)

$scope.checkSubmit = function () {

   if ($scope.myForm.$valid) {
        alert('All good...'); //next step!

   }
   else {
        alert('Not all fields valid! Do something...');
    }

 }

Now, when you load your app the class 'has-error' will only be added when the form is submitted or the field has been touched. Instead of:
!myForm.username.$pristine

You could also use:
myForm.username.$dirty

If you use mutexes to protect all your data, you really shouldn't need to worry. Mutexes have always provided sufficient ordering and visibility guarantees.

Now, if you used atomics, or lock-free algorithms, you need to think about the memory model. The memory model describes precisely when atomics provide ordering and visibility guarantees, and provides portable fences for hand-coded guarantees.

Previously, atomics would be done using compiler intrinsics, or some higher level library. Fences would have been done using CPU-specific instructions (memory barriers).

For anyone seeking a solution that does not use the command line: ctrl+shift+t

This one works fine for me as the directories structure is not important for me.

scp -r USER@HOSTNAME:~/bench1/?cpu/p_?/image/ .

Assuming /bench1 is in the home directory of the current user. Also, change USER and HOSTNAME to the real values.

First find the location of your flutter sdk

Flutter SDK File: Write the below command on your terminal to download the flutter sdk

git clone https://github.com/flutter/flutter.git

For example: the SDK file name is flutter and it is in Downloads

Close and open your terminal again

and enter the following commands in your terminal

cd Downloads     #go to Downloads

cd flutter   #go to flutter

pwd       #/Users/[USERNAME]/downloads/flutter/

whoami      #Your [USERNAME]

export PATH="/Users/[USERNAME]/downloads/flutter/bin":$PATH

I hope you will manage on based on the example I have given. Upvote the answer if you find it useful.
