Without seeing said object list, I believe you should be binding to the DataGrid's ItemsSource property, not its DataContext.

<DataGrid x:Name="Imported" VerticalAlignment="Top" ItemsSource="{Binding Source=list}"  AutoGenerateColumns="False" CanUserResizeColumns="True">
    <DataGrid.Columns>                
        <DataGridTextColumn Header="ID" Binding="{Binding ID}"/>
        <DataGridTextColumn Header="Date" Binding="{Binding Date}"/>
   </DataGrid.Columns>
</DataGrid>

(This assumes that the element [UserControl, etc.] that contains the DataGrid has its DataContext bound to an object that contains the list collection. The DataGrid is derived from ItemsControl, which relies on its ItemsSource property to define the collection it binds its rows to. Hence, if list isn't a property of an object bound to your control's DataContext, you might need to set both DataContext={Binding list} and ItemsSource={Binding list} on the DataGrid...)

It is similar to x = (x >> 1).

(operand1)(operator)=(operand2)  implies(=>)  (operand1)=(operand1)(operator)(operand2) 

It shifts the binary value of x by one to the right.

E.g.

int x=3;    // binary form (011) 
x = x >> 1; // zero shifted in from the left, 1 shifted out to the right:
            // x=1, binary form (001)

I was having trouble with this issue and had tried everything that everyone had posted with no success. I finally was able to contact Google and got someone on the phone. With their help I had it fixed in minutes. Here's what worked for me...

1. Settings --> Applicaitons --> Manage Applications --> All
2. Select Download Manager; clear data; clear cache; go back
3. Select Google Play Store; clear data; clear cache; go back
4. Select Google Services Framework; clear data; clear cache; go back
5. Turn off phone
6. Turn on phone

It worked for me. Hope this helps someone. Also, be aware they did say that it could take a few minutes for it to work -- possibly up to 30 minutes after restarting the phone. I did notice when restarting the phone that the Google Play Store had to update itself first. But now it is resolved. Finally!

try this code

using hidden field we can pass php varibale to another page

page1.php

<?php $myVariable = "Some text";?>
<form method="post" action="page2.php">
 <input type="hidden" name="text" value="<?php echo $myVariable; ?>">
 <button type="submit">Submit</button>
</form>

pass php variable to hidden field value so you can access this variable into another page

page2.php

<?php
 $text=$_POST['text'];
 echo $text;
?>

On the contrary, I do think working with list makes it easy to automate such things.

Here is one solution (I stored your four dataframes in folder temp/).

filenames <- list.files("temp", pattern="*.csv", full.names=TRUE)
ldf <- lapply(filenames, read.csv)
res <- lapply(ldf, summary)
names(res) <- substr(filenames, 6, 30)

It is important to store the full path for your files (as I did with full.names), otherwise you have to paste the working directory, e.g.

filenames <- list.files("temp", pattern="*.csv")
paste("temp", filenames, sep="/")

will work too. Note that I used substr to extract file names while discarding full path.

You can access your summary tables as follows:

> res$`df4.csv`
       A              B        
 Min.   :0.00   Min.   : 1.00  
 1st Qu.:1.25   1st Qu.: 2.25  
 Median :3.00   Median : 6.00  
 Mean   :3.50   Mean   : 7.00  
 3rd Qu.:5.50   3rd Qu.:10.50  
 Max.   :8.00   Max.   :16.00  

If you really want to get individual summary tables, you can extract them afterwards. E.g.,

for (i in 1:length(res))
  assign(paste(paste("df", i, sep=""), "summary", sep="."), res[[i]])

For MySQL, use:

DESCRIBE name_of_table;

This also works for Oracle as long as you are using SQL*Plus, or Oracle's SQL Developer.

If you want to copy everything in a Folder + have a special Port use this one. Works for me on Ubuntu 18.04 and a local machine with Mac OS X.

-r for recursive
-P for Port

scp -rP 1234 /Your_Directory/Source_Folder/ [email protected]:/target/folder

maybe for someone it will be useful

for Postgresql 9.5 works as a charm

INSERT INTO tabelname(id, col2, col3, col4)
VALUES
    (1, 1, 1, 'text for col4'),
    (DEFAULT,1,4,'another text for col4')
ON CONFLICT (id) DO UPDATE SET
    col2 = EXCLUDED.col2,
    col3 = EXCLUDED.col3,
    col4 = EXCLUDED.col4

this SQL updates existing record and inserts if new one (2 in 1)

% ps -o args -C nginx
COMMAND
build/sbin/nginx -c ../test.conf

If nginx was run without the -c option, then you can use the -V option to find out the configure arguments that were set to non-standard values. Among them the most interesting for you are:

--prefix=PATH                      set installation prefix
--sbin-path=PATH                   set nginx binary pathname
--conf-path=PATH                   set nginx.conf pathname

You need to add a reference inside the window tag. Something like:

xmlns:controls="clr-namespace:YourCustomNamespace.Controls;assembly=YourAssemblyName"

(When you add xmlns:controls=" intellisense should kick in to make this bit easier)

Then you can add the control with:

<controls:CustomControlClassName ..... />

I would all but guarantee that the issue is some sort of non-printing character that's present in the value you pulled off your socket. It looks like you're using Python 2.x, in which case you can check for them with this:

print repr(temp)

You'll likely see something in there that's escaped in the form \x00. These non-printing characters don't show up when you print directly to the console, but their presence is enough to negatively impact the parsing of a string value into a float.

-- Edited for question changes --

It turns this is partly accurate for your issue - the root cause however appears to be that you're reading more information than you expect from your socket or otherwise receiving multiple values. You could do something like

map(float, temp.strip().split('\r\n'))

In order to convert each of the values, but if your function is supposed to return a single float value this is likely to cause confusion. Anyway, the issue certainly revolves around the presence of characters you did not expect to see in the value you retrieved from your socket.

You could do

telnet stackoverflow.com 80

And then paste

GET /questions HTTP/1.0
Host: stackoverflow.com


# add the 2 empty lines above but not this one

Here is a transcript

$ telnet stackoverflow.com 80

Just sort the array in ascending order and print it backwards.

Arrays.sort(arr);
for(int i = arr.length-1; i >= 0 ; i--) {
    //print arr[i]
}

Fluid layout in Bootstrap 3.

Unlike Boostrap 2, Bootstrap 3 doesn't have a .container-fluid mixin to make a fluid container. The .container is a fixed width responsive grid layout. In a large screen, there are excessive white spaces in both sides of one's Web page content.

container-fluid is added back in Bootstrap 3.1

A fluid grid layout uses all screen width and works better in large screen. It turns out that it is easy to create a fluid grid layout using Bootstrap 3 mixins. The following line makes a fluid responsive grid layout:

.container-fixed;

The .container-fixed mixin sets the content to the center of the screen and add paddings. It doesn't specifies a fixed page width.

Another approach is to use Eric Flowers' CSS style

.my-fluid-container {
    padding-left: 15px;
    padding-right: 15px;
    margin-left: auto;
    margin-right: auto;
}

# mysqladmin -u root -p status

Output:

Enter password:
Uptime: 4  Threads: 1  Questions: 62  Slow queries: 0  Opens: 51  Flush tables: 1  Open tables: 45  Queries per second avg: 15.500

It means MySQL serer is running

If server is not running then it will dump error as follows

# mysqladmin -u root -p status

Output :

mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)'
Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock' exists!

So Under Debian Linux you can type following command

# /etc/init.d/mysql status

I had the same problem. It worked for me when i removed the private modifier from the Autowired objects.

Is there a command that does?

thread apply all where

As an alternative to the answers you already have, and for others that come accross this post. I recently had a similar task and created a small jquery plug in to do it for me. Its pretty small under 3KB minified, and has sorting, paging and the ability to show and hide columns.

It should be pretty easy to customize using css. More information can be found here http://mrjsontable.azurewebsites.net/ and the project is available for you to do as you wish with on github https://github.com/MatchingRadar/Mr.JsonTable

To get it to work download the files and pop them in your site. Follow the instructions and you should end up with something like the following:

<div id="citytable"></div>

Then in the ajax success method you will want something like this

success: function(data){ 
    $("#citytable").mrjsontable({
        tableClass: "my-table",
        pageSize: 10, //you can change the page size here
        columns: [
            new $.fn.mrjsontablecolumn({
                heading: "City",
                data: "city"
            }),
            new $.fn.mrjsontablecolumn({
                heading: "City Status",
                data: "cStatus"
            })
        ],
        data: data
    });
}

Hope it helps somebody else!

My version written in typescript:

function changeColorLightness(color: number, lightness: number): number {
    return (Math.max(0, Math.min(((color & 0xFF0000) / 0x10000) + lightness, 0xFF)) * 0x10000) +
        (Math.max(0, Math.min(((color & 0x00FF00) / 0x100) + lightness, 0xFF)) * 0x100) +
        (Math.max(0, Math.min(((color & 0x0000FF)) + lightness, 0xFF)));
}

explanation:

export function changeColorLightness(color: number, lightness: number): number {
    const r = (color & 0xFF0000) / 0x10**4;
    const g = (color & 0x00FF00) / 0x10**2;
    const b = (color & 0x0000FF);

    const changedR = Math.max(0, Math.min(r + lightness, 0xFF));
    const changedG = Math.max(0, Math.min(g + lightness, 0xFF));
    const changedB = Math.max(0, Math.min(b + lightness, 0xFF));

    return (changedR * 0x10**4) + (changedG * 0x10**2) + changedB;
}

usage:

changeColorLightness(0x00FF00, 0x50);
changeColorLightness(parseInt("#00FF00".replace('#',''), 16), 0x50);
changeColorLightness(0x00FF00, 127.5);

This method works:

audio.pause();
audio.currentTime = 0;

But if you don't want to have to write these two lines of code every time you stop an audio you could do one of two things. The second I think is the more appropriate one and I'm not sure why the "gods of javascript standards" have not made this standard.

First method: create a function and pass the audio

function stopAudio(audio) {
    audio.pause();
    audio.currentTime = 0;
}

//then using it:
stopAudio(audio);

Second method (favoured): extend the Audio class:

Audio.prototype.stop = function() {
    this.pause();
    this.currentTime = 0;
};

I have this in a javascript file I called "AudioPlus.js" which I include in my html before any script that will be dealing with audio.

Then you can call the stop function on audio objects:

audio.stop();

FINALLY CHROME ISSUE WITH "canplaythrough":

I have not tested this in all browsers but this is a problem I came across in Chrome. If you try to set currentTime on an audio that has a "canplaythrough" event listener attached to it then you will trigger that event again which can lead to undesirable results.

So the solution, similar to all cases when you have attached an event listener that you really want to make sure it is not triggered again, is to remove the event listener after the first call. Something like this:

//note using jquery to attach the event. You can use plain javascript as well of course.
$(audio).on("canplaythrough", function() {
    $(this).off("canplaythrough");

    // rest of the code ...
});

BONUS:

Note that you can add even more custom methods to the Audio class (or any native javascript class for that matter).

For example if you wanted a "restart" method that restarted the audio it could look something like:

Audio.prototype.restart= function() {
    this.pause();
    this.currentTime = 0;
    this.play();
};

select Country_id,country_title from(
   select Country_id,country_title,row_number() over (partition by country_title 
   order by Country_id  ) rn from country)a
   where rn=1;

Here is a solution if you need to hook up some methods to @User for use in your views. No solution for any serious membership customization, but if the original question was needed for views alone then this perhaps would be enough. The below was used for checking a variable returned from a authorizefilter, used to verify if some links wehere to be presented or not(not for any kind of authorization logic or access granting).

using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Web;
    using System.Security.Principal;

    namespace SomeSite.Web.Helpers
    {
        public static class UserHelpers
        {
            public static bool IsEditor(this IPrincipal user)
            {
                return null; //Do some stuff
            }
        }
    }

Then just add a reference in the areas web.config, and call it like below in the view.

@User.IsEditor()

You need to make sure that the previous container you launched is killed, before launching a new one that uses the same port.

docker container ls
docker rm -f <container-name>

I would recommend you to change Status cache of the Overlays.

Settings -> Icon Overlays -> Status cache

Maybe this would help to reinitialise the cache.

Be sure touse the latest version of Tortoise.

while the popular answer with extends {} works and is better than extends any, it forces the T to be an object

const foo = <T extends {}>(x: T) => x;

to avoid this and preserve the type-safety, you can use extends unknown instead

const foo = <T extends unknown>(x: T) => x;

I as well as you faced a problem of work angular.copy and angular.expect because they do not copy the object or create the object without adding some dependencies. My solution was this:

  copyFactory = (() ->
    resource = ->
      resource.__super__.constructor.apply this, arguments
      return
    this.extendTo resource
    resource
  ).call(factory)

You may find likr

$('.class').find('tag').attr('src');

$(OutDir) turned out to be a relative path in VS2013, so I had to combine it with $(ProjectDir) to achieve the desired effect:

xcopy /y /d  "$(ProjectDir)External\*.dll" "$(ProjectDir)$(OutDir)"

BTW, you can easily debug the scripts by adding 'echo ' at the beginning and observe the expanded text in the build output window.

If you use IIS Windows Server add web.config file in root folder and put the below code :

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <rule name="Imported Rule 1" stopProcessing="true">
                    <match url="^(.*)$" ignoreCase="false" />
                    <conditions logicalGrouping="MatchAll">
                        <add input="{URL}" pattern="^system.*" ignoreCase="false" />
                    </conditions>
                    <action type="Rewrite" url="/index.php/{R:1}" />
                </rule>
                <rule name="Imported Rule 2" stopProcessing="true">
                    <match url="^(.*)$" ignoreCase="false" />
                    <conditions logicalGrouping="MatchAll">
                        <add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" negate="true" />
                        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" negate="true" />
                        <add input="{R:1}" pattern="^(index\.php|images|robots\.txt|css)" ignoreCase="false" negate="true" />
                    </conditions>
                    <action type="Rewrite" url="index.php/{R:1}" />
                </rule>
            </rules>
        </rewrite>
    </system.webServer>
</configuration>

and if you use .htaccess use this one :

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

Since protobuf release 3.15, proto3 supports using the optional keyword (just as in proto2) to give a scalar field presence information.

syntax = "proto3";

message Foo {
    int32 bar = 1;
    optional int32 baz = 2;
}

A has_baz()/hasBaz() method is generated for the optional field above, just as it was in proto2.

Under the hood, protoc effectively treats an optional field as if it were declared using a oneof wrapper, as CyberSnoopy’s answer suggested:

message Foo {
    int32 bar = 1;
    oneof optional_baz {
        int32 baz = 2;
    }
}

If you’ve already used that approach, you can now simplify your message declarations (switch from oneof to optional) and code, since the wire format is the same.

The nitty-gritty details about field presence and optional in proto3 can be found in the Application note: Field presence doc.

Historical note: Experimental support for optional in proto3 was first announced on Apr 23, 2020 in this comment. Using it required passing protoc the --experimental_allow_proto3_optional flag in releases 3.12-3.14.

try this:

$endOfCycle = date("Y-m", time()+2592000);

this adds 30 days, not exactly a month tough.

Right click your project--->Build path---->configure Build path----> Libraries Tab--->Add External jars--->(Navigate to the location where you have kept the sql driver jar)--->ok

This would work fine.

Push-Location $PSScriptRoot

Write-Host CurrentDirectory $CurDir

The another trick is by setting the parent loop to reach the end and then break the current loop

function foo()
{
    for(var k = 0; k < 4; k++){
        for(var m = 0; m < 4; m++){
            if(m == 2){
                k = 5; // Set this then break
                break;
            }
          console.log(m);
        }
    }
}

Use padding-left:1em; text-indent:-1em for the <li> tag.
Then, list-style-position: inside for the <ul> tag.

<ul style='list-style-position: inside;'>
  <li style='padding-left: 1em; text-indent: -1em;'>Item 1</li>
</ul>

Use below command:

$ git reset HEAD~1

After this you also able to view files what revert back like below response.

Unstaged changes after reset:
M   application/config/config.php
M   application/config/database.php

The issue with my designer was 32 vs 64 bit issue. I could add the control to tool box after following the instructions in Cannot add Controls from 64-bit Assemblies to the Toolbox or Use in Designers Within the Visual Studio IDE MS KB article.

Python:

python -c "from datetime import datetime; print(datetime.fromtimestamp($TIMESTAMP))"

If you're on a Unix-like system, use gettimeofday and convert the result from microseconds to milliseconds.

I had read yesterday that the issue was fixed for someone when that person cleared cookies. I had tried that but it did not work for me.

Checking the following section in DatabaseInterface.class.php,

        define(
            'PMA_MYSQL_INT_VERSION',
            PMA_Util::cacheGet('PMA_MYSQL_INT_VERSION', true)
        );

I figured that somehow cache is the problem. So, I remembered that I was restarting the service instead of doing a start and stop.

# restart the service
systemd restart php-fpm

# start and stop the service
systemd stop php-fpm
systemd start php-fpm

Doing a stop followed by a start fixed the issue for me.

A much simpler solution, without all the inside form-group elements

My code was out of void setup() or void loop() in Arduino.

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

If you want to change the range to [0, 1], make sure the output data type is float.

image = cv2.imread("lenacolor512.tiff", cv2.IMREAD_COLOR)  # uint8 image
norm_image = cv2.normalize(image, None, alpha=0, beta=1, norm_type=cv2.NORM_MINMAX, dtype=cv2.CV_32F)

All of these look like overkill (or don't work)... just do this:

$http.post(loginUrl, `username=${ encodeURIComponent(username) }` +
                     `&password=${ encodeURIComponent(password) }` +
                     '&grant_type=password'
).success(function (data) {

Just a reminder you can't initialise DataTable on the same <table> element twice.

If you encounter same issue then you can set searching and paging false while initializing DataTable on your HTML <table> like this

 $('#tbl').DataTable({
    searching: false, 
    paging: false,
    dom: 'Bfrtip',
    buttons: [
       'copy', 'csv', 'excel', 'pdf', 'print'
    ]
 });

As Mingyu pointed out, there is a problem in formatting. Other than that, I would strongly recommend not using the Derived class's name while calling super() since it makes your code inflexible (code maintenance and inheritance issues). In Python 3, Use super().__init__ instead. Here is the code after incorporating these changes :

class Car(object):
    condition = "new"

    def __init__(self, model, color, mpg):
        self.model = model
        self.color = color
        self.mpg   = mpg

class ElectricCar(Car):

    def __init__(self, battery_type, model, color, mpg):
        self.battery_type=battery_type
        super().__init__(model, color, mpg)

Thanks to Erwin Mayer for pointing out the issue in using __class__ with super()

To add a little light to this, I would have to go with the pdf.js solution from Mozilla. Here is the link to an already well written implementation of this: https://bitbucket.org/butelo/pdfviewer/.

Here are the edits that I added in my Android Activity:

private String getInternalPDFURL(String interalPDFName){
    return "file:///android_asset/pdfviewer/index.html?pdf=" + interalPDFName + ".pdf";
}

Here are the edits I made in pdffile.js:

var url = '../' + getPDFURL();

function getPDFURL(){
    var query = window.location.search.substring(1);
    var vars = query.split("=");
    var pdfPage = vars[1];
    return pdfPage;
}

You might want to consider using console.log with the built-in "arguments" object:

This will always output all of your arguments, no matter how many arguments you have.

Hibernate tries to insert data that violate underlying database integrity contraints.

There's probably misconfiguration in hibernate persistent classes and/or mapping configuration (*.hbm.xml or annotations in persitent classes).

Maybe a property of the bean you want to save is not type-compatible with its related field in database (could explain the constraint [numbering] part).

I'm suggest that you learn about Jquery, most popular JS library. With jquery it's simple to acomplish what you want.Simle example below:

$(“#DIV_YOU_WANT_CHANGE”).click(function() {
    $(this).addClass(“.your_class_with_new_color”);
}); 

I had the same error, the problem was that I was trying to add role_id foreign to the users table, but role_id did not have a default value, so the DB did not allow me to insert the column because I already had some users and it didn't know how to add the column to them. Since I was in development I just used migrate:fresh, but if I was on production, I would probably set a default value to the role_id and not make it not constrained until I had the corresponding role on the DB.

Curious.....at least on Windows (my npm is 3.something) I needed to do:

"dependencies": {
 "body-parser": "^1.17.1",
 "module1": "../module1",
 "module2": "../module2",

When I did an npm install ../module1 --save it resulted in absolute paths and not relative per the documentation.

I messed around a little more and determined that ../xxx was sufficient.

Specifically, I have the local node modules checked out to say d:\build\module1, d:\build\module2 and my node project (application) in d:\build\nodeApp.

To 'install', I:

d:\build\module1> rmdir "./node_modules" /q /s && npm install
d:\build\module2> rmdir "./node_modules" /q /s && npm install
d:\build\nodeApp> rmdir "./node_modules" /q /s && npm install

module1's package.json has a dependency of "module2": "../module2"; module2 has no local dependency; nodeApp has dependencies "module1": "../module1" and "module2": "../module2".

Not sure if this only works for me since all 3 folders (module1, module2 and nodeApp) sit on that same level.......

This will solve the problem of getting "Class 'PDO' not found" when you create a local php.ini file.

If you can't turn off magic quotes using the htaccess file (for reasons already given by Pete Bailey) just:

1. Create a text file
2. Rename it to 'php.ini'

3. Add the lines

   magic_quotes_gpc = Off
   magic_quotes_runtime = Off
   magic_quotes_sybase = Off
   extension=pdo.so
   extension=pdo_mysql.so

4. Save it to the directory/ies in which your scripts are executing.

Update: if you want to have just one copy of the new php.ini file then add this line to your root .htaccess file:

SetEnv PHPRC /path/to/site/root/public_html/php.ini

Obviously you need to move the ini file to this location of it's not there already.

Hope that saves someone the 2 hours it's just taken me!

A solution using retype() from hablar to coerce factors to character or numeric type depending on feasability. I'd use dplyr for applying max to each column.

Code

library(dplyr)
library(hablar)

# Retype() simplifies each columns type, e.g. always removes factors
d <- d %>% retype()

# Check max for each column
d %>% summarise_all(max)

Result

Not the new column types.

     v1 v2       v3 v4   
  <dbl> <chr> <dbl> <chr>
1 0.974 j      1.09 J   

Data

# Sample data borrowed from @joran
d <- data.frame(v1 = runif(10), v2 = letters[1:10], 
                v3 = rnorm(10), v4 = LETTERS[1:10],stringsAsFactors = TRUE)

depends on the application. if there is only a few packages from each client, 100K is very easy for linux. A engineer of my team had done a test years ago, the result shows : when there is no package from client after connection established, linux epoll can watch 400k fd for readablity at cpu usage level under 50%.

For running without any browser, you can run it in headless mode.

I show you one example in Python that is working for me right now

from selenium import webdriver


options = webdriver.ChromeOptions()
options.add_argument("headless")
self.driver = webdriver.Chrome(executable_path='/Users/${userName}/Drivers/chromedriver', chrome_options=options)

I also add you a bit more of info about this in the official Google website https://developers.google.com/web/updates/2017/04/headless-chrome

You can avoid a useless use of cat and handle mismatched quotes better with this:

$ read -r -d '' VAR <<'EOF'
abc'asdf"
$(dont-execute-this)
foo"bar"''
EOF

If you don't quote the variable when you echo it, newlines are lost. Quoting it preserves them:

$ echo "$VAR"
abc'asdf"
$(dont-execute-this)
foo"bar"''

If you want to use indentation for readability in the source code, use a dash after the less-thans. The indentation must be done using only tabs (no spaces).

$ read -r -d '' VAR <<-'EOF'
    abc'asdf"
    $(dont-execute-this)
    foo"bar"''
    EOF
$ echo "$VAR"
abc'asdf"
$(dont-execute-this)
foo"bar"''

If, instead, you want to preserve the tabs in the contents of the resulting variable, you need to remove tab from IFS. The terminal marker for the here doc (EOF) must not be indented.

$ IFS='' read -r -d '' VAR <<'EOF'
    abc'asdf"
    $(dont-execute-this)
    foo"bar"''
EOF
$ echo "$VAR"
    abc'asdf"
    $(dont-execute-this)
    foo"bar"''

Tabs can be inserted at the command line by pressing Ctrl-V Tab. If you are using an editor, depending on which one, that may also work or you may have to turn off the feature that automatically converts tabs to spaces.

I'd prefer mapping after making sure the value is available

private String getStringIfObjectIsPresent(Optional<Object> object) {
   Object ob = object.orElseThrow(MyCustomException::new);
    // do your mapping with ob
   String result = your-map-function(ob);
  return result;
}

or one liner

private String getStringIfObjectIsPresent(Optional<Object> object) {
   return your-map-function(object.orElseThrow(MyCustomException::new));
}

Another thing that people may find useful...make sure to leave off ".py" from your module name. For example, if you are trying to generate documentation for 'original' in 'original.py':

yourcode_dir$ pydoc -w original.py
no Python documentation found for 'original.py'

yourcode_dir$ pydoc -w original
wrote original.html

If the queries you are interested in are dynamic queries that fail intermittently, you could log the SQL and the datetime and user in a table at the time the dynamic statement is created. It would be done on a case-by case basis though as it requires specific programming to happen and it takes a littel extra processing time, so do it only for those few queries you are most concerned about. But having a log of the specific statements executed can really help when you are trying to find out why it fails once a month only. Dynamic queries are hard to thoroughly test and sometimes you get one specific input value that just won't work and doing this logging at the time the SQL is created is often the best way to see what specifically wasn in the sql that was built.

Yes, provided you have access to the object definition and can modify it to declare the custom event

public event EventHandler<EventArgs> ModelChanged;

And normally you'd back this up with a private method used internally to invoke the event:

private void OnModelChanged(EventArgs e)
{
    if (ModelChanged != null)
        ModelChanged(this, e);
}

Your code simply declares a handler for the declared myMethod event (you can also remove the constructor), which would get invoked every time the object triggers the event.

myObject.myMethod += myNameEvent;

Similarly, you can detach a handler using

myObject.myMethod -= myNameEvent;

Also, you can write your own subclass of EventArgs to provide specific data when your event fires.

I hope you won't mind a slight tangent, but thought you may be interested to know that besides F (for float), D (for double), and L (for long), a proposal has been made to add suffixes for byte and short—Y and S respectively. This would eliminate to the need to cast to bytes when using literal syntax for byte (or short) arrays. Quoting the example from the proposal:

MAJOR BENEFIT: Why is the platform better if the proposal is adopted?

cruddy code like

 byte[] stuff = { 0x00, 0x7F, (byte)0x80,  (byte)0xFF};

can be recoded as

 byte[] ufum7 = { 0x00y, 0x7Fy, 0x80y, 0xFFy };

Joe Darcy is overseeing Project Coin for Java 7, and his blog has been an easy way to track these proposals.

To delete a web property, you simply need to delete every profile within the property. Once the last profile has been deleted, the web property with cease to exist in the GA account. That's all there is to it! -- Source

There can only be one public class top level class in a file. The class name of that public class should be the name of the file. It can have many public inner classes.

You can have many classes in a single file. The limits for various levels of class visibility in a file are as follows:

Top level classes:
1 public class
0 private class
any number of default/protected classes

Inner classes:
any number of inner classes with any visibility (default, private, protected, public)

Please correct me if I am wrong.

rekaszeru

I noticed that you commented in 2011 but i thought i should post this answer anyway, in case anyone needs to "replace the original string" and runs into this answer ..

Im using a EditText as an example

// GIVE TARGET TEXT BOX A NAME

 EditText textbox = (EditText) findViewById(R.id.your_textboxID);

// STRING TO REPLACE

 String oldText = "hello"
 String newText = "Hi";      
 String textBoxText = textbox.getText().toString();

// REPLACE STRINGS WITH RETURNED STRINGS

String returnedString = textBoxText.replace( oldText, newText );

// USE RETURNED STRINGS TO REPLACE NEW STRING INSIDE TEXTBOX

textbox.setText(returnedString);

This is untested, but it's just an example of using the returned string to replace the original layouts string with setText() !

Obviously this example requires that you have a EditText with the ID set to your_textboxID

There are several ways to get a string length:

package main

import (
    "bytes"
    "fmt"
    "strings"
    "unicode/utf8"
)

func main() {
    b := "?????"
    len1 := len([]rune(b))
    len2 := bytes.Count([]byte(b), nil) -1
    len3 := strings.Count(b, "") - 1
    len4 := utf8.RuneCountInString(b)
    fmt.Println(len1)
    fmt.Println(len2)
    fmt.Println(len3)
    fmt.Println(len4)

}

To create a new line, symbol is '\n'

var i;
for(i=10; i>=0; i= i-1){
   var s;
   for(s=0; s<i; s = s+1){
    document.write("*");
   }
   //i want this to print a new line
   document.write('\n');

}

If you are outputting to the page, you'll want to use "<br/>" instead of '/n';

I know the question is seeking a regex solution but in every attempt it won't work to cover everything

I decided to write this method in Python which only works with urls that have a subdomain (i.e. www.mydomain.co.uk) and not multiple level subdomains like www.mail.yahoo.com

def urlextract(url):
  url_split=url.split(".")
  if len(url_split) <= 2:
      raise Exception("Full url required with subdomain:",url)
  return {'subdomain': url_split[0], 'domain': url_split[1], 'suffix': ".".join(url_split[2:])}

Client side Upload Canceling

On modern browsers (FF >= 3.6, Chrome >= 19.0, Opera >= 12.0, and buggy on Safari), you can use the HTML5 File API. When the value of a file input changes, this API will allow you to check whether the file size is within your requirements. Of course, this, as well as MAX_FILE_SIZE, can be tampered with so always use server side validation.

<form method="post" enctype="multipart/form-data" action="upload.php">
    <input type="file" name="file" id="file" />
    <input type="submit" name="submit" value="Submit" />
</form>

<script>
document.forms[0].addEventListener('submit', function( evt ) {
    var file = document.getElementById('file').files[0];

    if(file && file.size < 10485760) { // 10 MB (this size is in bytes)
        //Submit form        
    } else {
        //Prevent default and display error
        evt.preventDefault();
    }
}, false);
</script>

Server Side Upload Canceling

On the server side, it is impossible to stop an upload from happening from PHP because once PHP has been invoked the upload has already completed. If you are trying to save bandwidth, you can deny uploads from the server side with the ini setting upload_max_filesize. The trouble with this is this applies to all uploads so you'll have to pick something liberal that works for all of your uploads. The use of MAX_FILE_SIZE has been discussed in other answers. I suggest reading the manual on it. Do know that it, along with anything else client side (including the javascript check), can be tampered with so you should always have server side (PHP) validation.

PHP Validation

On the server side you should validate that the file is within the size restrictions (because everything up to this point except for the INI setting could be tampered with). You can use the $_FILES array to find out the upload size. (Docs on the contents of $_FILES can be found below the MAX_FILE_SIZE docs)

upload.php

<?php
if(isset($_FILES['file'])) {
    if($_FILES['file']['size'] > 10485760) { //10 MB (size is also in bytes)
        // File too big
    } else {
        // File within size restrictions
    }
}

In Laravel, I'm use:

private function getValueFromString(string $string, string $key)
{
    parse_str(parse_url($string, PHP_URL_QUERY), $result);

    return isset($result[$key]) ? $result[$key] : null;
}

Your local port is using by another app. I faced the same problem! You can try the following step:

1. Go to command line and run it as administrator!

2. Type:

   netstat -ano | find ":5000"
   => TCP    0.0.0.0:5000           0.0.0.0:0              LISTENING       4032
      TCP    [::]:5000              [::]:0                 LISTENING       4032
   

3. Type:

   TASKKILL /F /PID 4032
   

=> SUCCESS: The process with PID 4032 has been terminated.

Note: My 5000 local port was listing by PID 4032. You should give yours!

Difference between database and flat files are given below:

• Database provide more flexibility whereas flat file provide less flexibility.

• Database system provide data consistency whereas flat file can not provide data consistency.

• Database is more secure over flat files.

• Database support DML and DDL whereas flat files can not support these.

• Less data redundancy in database whereas more data redundancy in flat files.

If an existing (non-bare) checkout begins giving this error, check your .git/config file; if core.bare is true, remove that config line

Another solution:

cat file1 | tee -a file2

tee has the benefit that you can append to as many files as you like, for example:

cat file1 | tee -a file2 file3 file3

will append the contents of file1 to file2, file3 and file4.

From the man page:

-a, --append
       append to the given FILEs, do not overwrite

Are you using php 5.4 on your local? the render line is using the new way of initializing arrays. Try replacing ["title" => "Welcome "] with array("title" => "Welcome ")

You could also use it clean and simple (but wrong! because you should use format like Mark Byers said) by doing:

print 'This is my %s formatted with %d arguments' % ('string', 2)

The solution that worked for me is:

• use suptitle() for the actual title
• use title() for the subtitle and adjust it using the optional parameter y:

    import matplotlib.pyplot as plt
    """
            some code here
    """
    plt.title('My subtitle',fontsize=16)
    plt.suptitle('My title',fontsize=24, y=1)
    plt.show()

There can be some nasty overlap between the two pieces of text. You can fix this by fiddling with the value of y until you get it right.

As this seems to be a problem I have myself encountered multiple times and this time none of the shared solutions helped me, I'll still post what helped me personally and what I believe may help someone else in future:

Go to your project's directory and find build/intermediates/dex-cache/cache file. Remove it - as name suggests, it's a cached dex file that may be outdated if you have made changes to your project's dependencies, build tools version etc.

You have to refer to the documentation for ctime. time is a function that takes one parameter of type time_t * (a pointer to a time_t object) and assigns to it the current time. Instead of passing this pointer, you can also pass NULL and then use the returned time_t value instead.

As of pandas 0.17.0, DataFrame.sort() is deprecated, and set to be removed in a future version of pandas. The way to sort a dataframe by its values is now is DataFrame.sort_values

As such, the answer to your question would now be

df.sort_values(['b', 'c'], ascending=[True, False], inplace=True)

This works with Bootstrap 4.1.3:

<script>
    $("input[type=file]").change(function () {
        var fieldVal = $(this).val();

        // Change the node's value by removing the fake path (Chrome)
        fieldVal = fieldVal.replace("C:\\fakepath\\", "");

        if (fieldVal != undefined || fieldVal != "") {
            $(this).next(".custom-file-label").attr('data-content', fieldVal);
            $(this).next(".custom-file-label").text(fieldVal);
        }
    });
</script>

Use the P format string. This will vary by culture:

String.Format("Value: {0:P2}.", 0.8526) // formats as 85.26 % (varies by culture)

Rda is just a short name for RData. You can just save(), load(), attach(), etc. just like you do with RData.

Rds stores a single R object. Yet, beyond that simple explanation, there are several differences from a "standard" storage. Probably this R-manual Link to readRDS() function clarifies such distinctions sufficiently.

So, answering your questions:

• The difference is not about the compression, but serialization (See this page)
• Like shown in the manual page, you may wanna use it to restore a certain object with a different name, for instance.
• You may readRDS() and save(), or load() and saveRDS() selectively.

You can fix that by running this: On Fedora:

sudo dnf install redhat-rpm-config

If you go the brew route, the best way to install would be:

brew install macvim --with-override-system-vim

That will provide mvim, vim, vi, view, etc. in /usr/local/bin (all symlinked to the copy in the Cellar). This also removes the need to create any aliases and also changes your vi, vim, etc. to all use the same Vim distribution as your MacVim.

Here is an example. You enter a number (or whatever) in the textbox and press "add" to put it in the array. Then you press "show" to show the array items as elements.

<script type="text/javascript">

var arr = [];

function add() {
   var inp = document.getElementById('num');
   arr.push(inp.value);
   inp.value = '';
}

function show() {
   var html = '';
   for (var i=0; i<arr.length; i++) {
      html += '<div>' + arr[i] + '</div>';
   }
   var con = document.getElementById('container');
   con.innerHTML = html;
}

</script>

<input type="text" id="num" />
<input type="button" onclick="add();" value="add" />
<br />
<input type="button" onclick="show();" value="show" />
<div id="container"></div>

The errors actually vary. It's helpful to run ./emulator with -verbose option, as it will show the actual errors.

Vectors and matrices can only be of a single type and cbind and rbind on vectors will give matrices. In these cases, the numeric values will be promoted to character values since that type will hold all the values.

(Note that in your rbind example, the promotion happens within the c call:

> c(10, "[]", "[[1,2]]")
[1] "10"      "[]"      "[[1,2]]"

If you want a rectangular structure where the columns can be different types, you want a data.frame. Any of the following should get you what you want:

> x = data.frame(v1=c(10, 20), v2=c("[]", "[]"), v3=c("[[1,2]]","[[1,3]]"))
> x
  v1 v2      v3
1 10 [] [[1,2]]
2 20 [] [[1,3]]
> str(x)
'data.frame':   2 obs. of  3 variables:
 $ v1: num  10 20
 $ v2: Factor w/ 1 level "[]": 1 1
 $ v3: Factor w/ 2 levels "[[1,2]]","[[1,3]]": 1 2

or (using specifically the data.frame version of cbind)

> x = cbind.data.frame(c(10, 20), c("[]", "[]"), c("[[1,2]]","[[1,3]]"))
> x
  c(10, 20) c("[]", "[]") c("[[1,2]]", "[[1,3]]")
1        10            []                 [[1,2]]
2        20            []                 [[1,3]]
> str(x)
'data.frame':   2 obs. of  3 variables:
 $ c(10, 20)              : num  10 20
 $ c("[]", "[]")          : Factor w/ 1 level "[]": 1 1
 $ c("[[1,2]]", "[[1,3]]"): Factor w/ 2 levels "[[1,2]]","[[1,3]]": 1 2

or (using cbind, but making the first a data.frame so that it combines as data.frames do):

> x = cbind(data.frame(c(10, 20)), c("[]", "[]"), c("[[1,2]]","[[1,3]]"))
> x
  c.10..20. c("[]", "[]") c("[[1,2]]", "[[1,3]]")
1        10            []                 [[1,2]]
2        20            []                 [[1,3]]
> str(x)
'data.frame':   2 obs. of  3 variables:
 $ c.10..20.              : num  10 20
 $ c("[]", "[]")          : Factor w/ 1 level "[]": 1 1
 $ c("[[1,2]]", "[[1,3]]"): Factor w/ 2 levels "[[1,2]]","[[1,3]]": 1 2

Change your method to look like this:

String curloc = current.toString();
String itemdesc = item.mDescription;
ArrayList<String> passing = new ArrayList<String>();
passing.add(itemdesc);
passing.add(curloc);
new calc_stanica().execute(passing); //no need to pass in result list

And change your async task implementation

public class calc_stanica extends AsyncTask<ArrayList<String>, Void, ArrayList<String>> {
ProgressDialog dialog;

    @Override
    protected void onPreExecute() {
        dialog = new ProgressDialog(baraj_mapa.this);
        dialog.setTitle("Calculating...");
        dialog.setMessage("Please wait...");
        dialog.setIndeterminate(true);
        dialog.show();
    }

    protected ArrayList<String> doInBackground(ArrayList<String>... passing) {
        ArrayList<String> result = new ArrayList<String>();
        ArrayList<String> passed = passing[0]; //get passed arraylist

        //Some calculations...

        return result; //return result
    }

    protected void onPostExecute(ArrayList<String> result) {
        dialog.dismiss();
        String minim = result.get(0);
        int min = Integer.parseInt(minim);
        String glons = result.get(1);
        String glats = result.get(2);
        double glon = Double.parseDouble(glons);
        double glat = Double.parseDouble(glats);
        GeoPoint g = new GeoPoint(glon, glat);
        String korisni_linii = result.get(3);
    }

UPD:

If you want to have access to the task starting context, the easiest way would be to override onPostExecute in place:

new calc_stanica() {
    protected void onPostExecute(ArrayList<String> result) {
      // here you have access to the context in which execute was called in first place. 
      // You'll have to mark all the local variables final though..
     }
}.execute(passing);

You can solve it just in 1 second!

just use this url:

http://127.0.0.1/phpmyadmin/

instead of

http://localhost/phpmyadmin/

I had this issue occurring in Xcode 10.3 after I switched over to my XCTest unit test target then back to the project run time target.

Turns out I had a different Teams selected in my provisioning profile for each target.

To fix it :

• Clean Build Folder

• Make sure all may targets are using the same Team. See Profile Signing under the general tab.

• If not using same Team for all targets, clean before switching to a build target with

  different team selected.

A better solution for "today" is:

SELECT * FROM jokes WHERE DATE(date) = DATE(NOW())

Try this:

long length = f.length();

You can't do it with "anonymous" type parameters (ie, wildcards that use ?), but you can do it with "named" type parameters. Simply declare the type parameter at method or class level.

import java.util.List;
interface A{}
interface B{}
public class Test<E extends B & A, T extends List<E>> {
    T t;
}

In xml file, put imeOptions="actionSearch" and inputType="text", maxLines="1":

<EditText
    android:id="@+id/search_box"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="@string/search"
    android:imeOptions="actionSearch"
    android:inputType="text"
    android:maxLines="1" />

You need to move type parameter to the method level to indicate that you have a generic method rather than generic class:

public class ArrayUtils {
    public static <T> E[] appendToArray(E[] array, E item) {
        E[] result = (E[])new Object[array.length+1];
        result[array.length] = item;
        return result;
    }
}

In my case, in which I validate the most manually and using Firefox (43.0.4), minlength and validity.tooShort are not available unfortunately.

Since I only need to have minimum lengths stored to proceed, an easy and handy way is to assign this value to another valid attribute of the input tag. In that case then, you can use min, max, and step properties from [type="number"] inputs.

Rather than storing those limits in an array it's easier to find it stored in the same input instead of getting the element id to match the array index.

public List<DealsCategory> DealCategory { get; set; }
int categoryid = Convert.ToInt16(dealsModel.DealCategory.Select(x => x.Id));

PHPSESSID is an auto generated session cookie by the server which contains a random long number which is given out by the server itself

Pattern based configs are scheduled for 2.0.0 release of ESLint. For now, however, you will have to create two separate tasks (as mentioned in the comments). One for tests and one for the rest of the code and run both of them, while providing different .eslintrc files.

P.S. There's a jest environment coming in the next release of ESLint, it will register all of the necessary globals.

Here is a solution that leverages the use of Path.GetFullPath as recommended in the answer by @SLaks.

In the code that I am including here, note that IsValidPath(string path) is designed such that the caller does not have to worry about exception handling.

You may also find that the method that it calls, TryGetFullPath(...), also has merit on its own when you wish to safely attempt to get an absolute path.

/// <summary>
/// Gets a value that indicates whether <paramref name="path"/>
/// is a valid path.
/// </summary>
/// <returns>Returns <c>true</c> if <paramref name="path"/> is a
/// valid path; <c>false</c> otherwise. Also returns <c>false</c> if
/// the caller does not have the required permissions to access
/// <paramref name="path"/>.
/// </returns>
/// <seealso cref="Path.GetFullPath"/>
/// <seealso cref="TryGetFullPath"/>
public static bool IsValidPath(string path)
{
    string result;
    return TryGetFullPath(path, out result);
}

/// <summary>
/// Returns the absolute path for the specified path string. A return
/// value indicates whether the conversion succeeded.
/// </summary>
/// <param name="path">The file or directory for which to obtain absolute
/// path information.
/// </param>
/// <param name="result">When this method returns, contains the absolute
/// path representation of <paramref name="path"/>, if the conversion
/// succeeded, or <see cref="String.Empty"/> if the conversion failed.
/// The conversion fails if <paramref name="path"/> is null or
/// <see cref="String.Empty"/>, or is not of the correct format. This
/// parameter is passed uninitialized; any value originally supplied
/// in <paramref name="result"/> will be overwritten.
/// </param>
/// <returns><c>true</c> if <paramref name="path"/> was converted
/// to an absolute path successfully; otherwise, false.
/// </returns>
/// <seealso cref="Path.GetFullPath"/>
/// <seealso cref="IsValidPath"/>
public static bool TryGetFullPath(string path, out string result)
{
    result = String.Empty;
    if (String.IsNullOrWhiteSpace(path)) { return false; }
    bool status = false;

    try
    {
        result = Path.GetFullPath(path);
        status = true;
    }
    catch (ArgumentException) { }
    catch (SecurityException) { }
    catch (NotSupportedException) { }
    catch (PathTooLongException) { }

    return status;
}

This is another related post Lombok not working with IntelliJ 2020.3 Community Edition which may resolve the question when user use lombook and IntelliJ 2020.3 CommunityEdition.

You need to return a view which has a friendly error message to the user

catch (Exception ex)
{
   // to do :log error
   return View("Error");
}

You should not be showing the internal details of your exception(like exception stacktrace etc) to the user. You should be logging the relevant information to your error log so that you can go through it and fix the issue.

If your request is an ajax request, You may return a JSON response with a proper status flag which client can evaluate and do further actions

[HttpPost]
public ActionResult Create(CustomerVM model)
{
  try
  {
   //save customer
    return Json(new { status="success",message="customer created"});
  }
  catch(Exception ex)
  {
    //to do: log error
   return Json(new { status="error",message="error creating customer"});
  }
} 

If you want to show the error in the form user submitted, You may use ModelState.AddModelError method along with the Html helper methods like Html.ValidationSummary etc to show the error to the user in the form he submitted.

You could also use:

echo. 2>foo

The debug output for echo. will almost definitely be empty.

To reverse a string without using reversed or [::-1], try something like:

def reverse(text):
    # Container for reversed string
    txet=""

    # store the length of the string to be reversed
    # account for indexes starting at 0
    length = len(text)-1

    # loop through the string in reverse and append each character
    # deprecate the length index
    while length>=0:
        txet += "%s"%text[length]
        length-=1
    return txet

 NSString * encodedString = (NSString *)CFURLCreateStringByAddingPercentEscapes(NUL,(CFStringRef)@"parameter",NULL,(CFStringRef)@"!*'();@&+$,/?%#[]~=_-.:",kCFStringEncodingUTF8 );

NSURL * url = [[NSURL alloc] initWithString:[@"address here" stringByAppendingFormat:@"?cid=%@",encodedString, nil]];

You should use @RequestParam on those resources with method = RequestMethod.GET

In order to post parameters, you must send them as the request body. A body like JSON or another data representation would depending on your implementation (I mean, consume and produce MediaType).

Typically, multipart/form-data is used to upload files.

Additional thoughts :

Ramdisk - setting the temp drive MySQL uses as a RAM disk, very easy to set up.

memcache - memcache server is easy to set up, use it to store the results of your queries for X amount of time.

2019's answer as this is still actively seen today

You should likely change the .container to .container-fluid, which will cause your container to stretch the entire screen. This will allow any div's inside of it to naturally stretch as wide as they need.

original hack from 2015 that still works in some situations

You should pull that div outside of the container. You're asking a div to stretch wider than its parent, which is generally not recommended practice.

If you cannot pull it out of the div for some reason, you should change the position style with this css:

.full-width-div {
    position: absolute;
    width: 100%;
    left: 0;
}

Instead of absolute, you could also use fixed, but then it will not move as you scroll.

I'm using 2 ways to get the same response: one of them use:

   os.path.basename(filename)

due to errors that I found in my script I changed to:

Path = filename[:(len(filename)-len(os.path.basename(filename)))]

it's a workaround due to python's '\\'

Hope this will help someone looking for a perfect answer

Copying a folder or file from a server with a port defined to another server or local machine

1. Go to a directory where you have admin rights preferably your home directory on the machine where you want to copy files to
2. Write the command below

scp -r -P port user@IP_address:/home/file/pathDirectory .

**Note:** The last . on the command directs it to copy everything in that folder to your directory of preference

SELECT SERVERPROPERTY('LicenseType') as Licensetype, 
       SERVERPROPERTY('NumLicenses') as LicenseNumber,
       SERVERPROPERTY('productversion') as Productverion, 
       SERVERPROPERTY ('productlevel')as ProductLevel, 
       SERVERPROPERTY ('edition') as SQLEdition,@@VERSION as SQLversion

I had installed evaluation edition.Refer screenshot

I think the correct way to do is

brew upgrade mongodb

It will upgrade the mongodb formula. If you want to upgrade all outdated formula, simply

brew upgrade

Start by figuring out what your current working directory is for your running script.
Add this line at the beginning:

puts Dir.pwd.

This will tell you in which current working directory ruby is running your script. You will most likely see it's not where you assume it is. Then make sure you're specifying pathnames properly for windows. See the docs here how to properly format pathnames for windows:

http://www.ruby-doc.org/core/classes/IO.html

Then either use Dir.chdir to change the working directory to the place where text.txt is, or specify the absolute pathname to the file according to the instructions in the IO docs above. That SHOULD do it...

EDIT

Adding a 3rd solution which might be the most convenient one, if you're putting the text files among your script files:

Dir.chdir(File.dirname(__FILE__))

This will automatically change the current working directory to the same directory as the .rb file that is running the script.

Kotlin Answer

for ((key, value) in map.entries) {
    // do something with `key`
    // so something with `value`
}

You may find other solutions that include filterValues. Just keep in mind that retrieving a Key value using filterValues will include braces [].

val key = map.filterValues {it = position}.keys

Could be because of restoring SQL Server 2012 version backup file into SQL Server 2008 R2 or even less.

The default (when created with the designer) is:

label.ForeColor = SystemColors.ControlText;

This should respect the system color settings (e.g. these "high contrast" schemes for visual impaired).

In my case I made the mistake of copying *ng-for= from the docs.

https://angular.io/guide/user-input

Correct me if I am wrong. But it seems *ng-for= has been changed to *ngFor=

How I did it:

final int numberOfSpaces = 22;
final char[] spaceArray = new char[numberOfSpaces];
Arrays.fill(spaces, ' ');

Now add it to your StringBuilder

stringBuilder.append(spaceArray);

or String

final String spaces = String.valueOf(spaceArray);

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

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

or

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

These answers seem strangely convoluted. Unless I'm missing something...if you want to convert numbers to letters, you can just stock them all in an array using a for loop then call on the number associated with that column letter. Like so

For intloop = 1 To 26
    colcheck(intloop) = Chr$(64 + intloop)
    For lenloop = 1 To 26
        colcheck((intloop * 26) + lenloop) = Chr$(64 + intloop) & Chr$(64 + lenloop)
        For terloop = 1 To 26
            colcheck((intloop * 676) + (lenloop * 26) + terloop) = Chr$(64 + intloop) & Chr$(64 + lenloop) & Chr$(64 + terloop)
            For qualoop = 1 To 26
                colcheck((intloop * 17576) + (lenloop * 676) + (terloop * 26) + qualoop) = Chr$(64 + intloop) & Chr$(64 + lenloop) & Chr$(64 + terloop) & Chr$(64 + qualoop)
            Next qualoop
        Next terloop
    Next lenloop
Next intloop

Then just use colcheck(yourcolumnnumberhere) and you will get the column heading associated with that letter (i.e. colcheck(703) = AAA

Indeed. The thing is that the 2008 R2 version is very tricky. The JTDs driver seems to work on some cases. In a certain server, the jTDS worked fine for an 2008 R2 instance. In another server, though, I had to use Microsoft's JBDC driver sqljdbc4.jar. But then, it would only work after setting the JRE environment to 1.6(or higher).

I used 1.5 for the other server, so I waisted a lot of time on this.

Tricky issue.

Forwarding the example by @ritiek, I'm a beginner in ML too, maybe this kind of formatting will help see the name instead of just class number.

images = np.vstack([x, y])

prediction = model.predict(images)

print(prediction)

i = 1

for things in prediction:  
    if(things == 0):
        print('%d.It is cancer'%(i))
    else:
        print('%d.Not cancer'%(i))
    i = i + 1

I've create a library, available on Packagist, that performs this function: https://packagist.org/packages/grasmash/yaml-expander

Example YAML file:

type: book
book:
  title: Dune
  author: Frank Herbert
  copyright: ${book.author} 1965
  protaganist: ${characters.0.name}
  media:
    - hardcover
characters:
  - name: Paul Atreides
    occupation: Kwisatz Haderach
    aliases:
      - Usul
      - Muad'Dib
      - The Preacher
  - name: Duncan Idaho
    occupation: Swordmaster
summary: ${book.title} by ${book.author}
product-name: ${${type}.title}

Example logic:

// Parse a yaml string directly, expanding internal property references.
$yaml_string = file_get_contents("dune.yml");
$expanded = \Grasmash\YamlExpander\Expander::parse($yaml_string);
print_r($expanded);

Resultant array:

array (
  'type' => 'book',
  'book' => 
  array (
    'title' => 'Dune',
    'author' => 'Frank Herbert',
    'copyright' => 'Frank Herbert 1965',
    'protaganist' => 'Paul Atreides',
    'media' => 
    array (
      0 => 'hardcover',
    ),
  ),
  'characters' => 
  array (
    0 => 
    array (
      'name' => 'Paul Atreides',
      'occupation' => 'Kwisatz Haderach',
      'aliases' => 
      array (
        0 => 'Usul',
        1 => 'Muad\'Dib',
        2 => 'The Preacher',
      ),
    ),
    1 => 
    array (
      'name' => 'Duncan Idaho',
      'occupation' => 'Swordmaster',
    ),
  ),
  'summary' => 'Dune by Frank Herbert',
);

A query's projection can only have one instance of a given name. As your WHERE clause shows, you have several tables with a column called ID. Because you are selecting * your projection will have several columns called ID. Or it would have were it not for the compiler hurling ORA-00918.

The solution is quite simple: you will have to expand the projection to explicitly select named columns. Then you can either leave out the duplicate columns, retaining just (say) COACHES.ID or use column aliases: coaches.id as COACHES_ID.

Perhaps that strikes you as a lot of typing, but it is the only way. If it is any comfort, SELECT * is regarded as bad practice in production code: explicitly named columns are much safer.

Note if you want add view in Full screen then only use below code

Add these extension of UIViewController

public extension UIViewController {
   internal func makeViewAsFullScreen() {
      var viewFrame:CGRect = self.view.frame
      if viewFrame.origin.y > 0 || viewFrame.origin.x > 0 {
        self.view.frame = UIScreen.main.bounds
      }
   }
}

Continue as normal adding process of subview

Now use in adding UIViewController's viewDidAppear

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)

     self.makeViewAsFullScreen()
}

Map is the static type of map, while HashMap is the dynamic type of map. This means that the compiler will treat your map object as being one of type Map, even though at runtime, it may point to any subtype of it.

This practice of programming against interfaces instead of implementations has the added benefit of remaining flexible: You can for instance replace the dynamic type of map at runtime, as long as it is a subtype of Map (e.g. LinkedHashMap), and change the map's behavior on the fly.

A good rule of thumb is to remain as abstract as possible on the API level: If for instance a method you are programming must work on maps, then it's sufficient to declare a parameter as Map instead of the stricter (because less abstract) HashMap type. That way, the consumer of your API can be flexible about what kind of Map implementation they want to pass to your method.

I just stumbled upon this great post. If you are just checking whether the data is of string type then maybe we can skip the loop and use this struct (in my humble opinion)

public static bool IsStringType(object data)
    {
        return (data.GetType().GetProperties().Where(x => x.PropertyType == typeof(string)).FirstOrDefault() != null);
    }

pretty old topic but this is maybe a help for someone searching for the problem where the above tips does not solved it.

I use

Write editTextBackground.xml in drawable folder in resources

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <stroke
        android:width="1dp"
        android:color="@color/borderColor" />
</shape>

don't forget to declare color in resources named borderColor.

and assign this background to the EditText in xml background attribute

<EditText
    android:id="@+id/text"
    android:background="@drawable/editTextBackground"
    />

and it'll set border to EditText.

UPDATE

You can change border of edit text without drawable by using style attribute

style="@style/Widget.AppCompat.EditText"

for more details visit customize edit text

Here it is:

[chr(i) for i in xrange(127)]

You can do simply by replacing html

$('#mySelect')
.html('<option value="whatever" selected>text</option>')
.trigger('change');

The Lazy Fetch type is by default selected by Hibernate unless you explicitly mark Eager Fetch type. To be more accurate and concise, difference can be stated as below.

FetchType.LAZY = This does not load the relationships unless you invoke it via the getter method.

FetchType.EAGER = This loads all the relationships.

Pros and Cons of these two fetch types.

Lazy initialization improves performance by avoiding unnecessary computation and reduce memory requirements.

Eager initialization takes more memory consumption and processing speed is slow.

Having said that, depends on the situation either one of these initialization can be used.

XSS can be prevented in JSP by using JSTL <c:out> tag or fn:escapeXml() EL function when (re)displaying user-controlled input. This includes request parameters, headers, cookies, URL, body, etc. Anything which you extract from the request object. Also the user-controlled input from previous requests which is stored in a database needs to be escaped during redisplaying.

For example:

<p><c:out value="${bean.userControlledValue}"></p>
<p><input name="foo" value="${fn:escapeXml(param.foo)}"></p>

This will escape characters which may malform the rendered HTML such as <, >, ", ' and & into HTML/XML entities such as <, >, ", ' and &.

Note that you don't need to escape them in the Java (Servlet) code, since they are harmless over there. Some may opt to escape them during request processing (as you do in Servlet or Filter) instead of response processing (as you do in JSP), but this way you may risk that the data unnecessarily get double-escaped (e.g. & becomes & instead of & and ultimately the enduser would see & being presented), or that the DB-stored data becomes unportable (e.g. when exporting data to JSON, CSV, XLS, PDF, etc which doesn't require HTML-escaping at all). You'll also lose social control because you don't know anymore what the user has actually filled in. You'd as being a site admin really like to know which users/IPs are trying to perform XSS, so that you can easily track them and take actions accordingly. Escaping during request processing should only and only be used as latest resort when you really need to fix a train wreck of a badly developed legacy web application in the shortest time as possible. Still, you should ultimately rewrite your JSP files to become XSS-safe.

If you'd like to redisplay user-controlled input as HTML wherein you would like to allow only a specific subset of HTML tags like <b>, <i>, <u>, etc, then you need to sanitize the input by a whitelist. You can use a HTML parser like Jsoup for this. But, much better is to introduce a human friendly markup language such as Markdown (also used here on Stack Overflow). Then you can use a Markdown parser like CommonMark for this. It has also builtin HTML sanitizing capabilities. See also Markdown or HTML.

The only concern in the server side with regard to databases is SQL injection prevention. You need to make sure that you never string-concatenate user-controlled input straight in the SQL or JPQL query and that you're using parameterized queries all the way. In JDBC terms, this means that you should use PreparedStatement instead of Statement. In JPA terms, use Query.

An alternative would be to migrate from JSP/Servlet to Java EE's MVC framework JSF. It has builtin XSS (and CSRF!) prevention over all place. See also CSRF, XSS and SQL Injection attack prevention in JSF.

Some advantages to the second option:

1. You can use this inside onclick to reference the anchor itself (doing the same in option 1 will give you window instead).

2. You can set the href to a non-JS compatible URL to support older browsers (or those that have JS disabled); browsers that support JavaScript will execute the function instead (to stay on the page you have to use onclick="return someFunction();" and return false from inside the function or onclick="return someFunction(); return false;" to prevent default action).

3. I've seen weird stuff happen when using href="javascript:someFunction()" and the function returns a value; the whole page would get replaced by just that value.

Pitfalls

Inline code:

1. Runs in document scope as opposed to code defined inside <script> tags which runs in window scope; therefore, symbols may be resolved based on an element's name or id attribute, causing the unintended effect of attempting to treat an element as a function.

2. Is harder to reuse; delicate copy-paste is required to move it from one project to another.

3. Adds weight to your pages, whereas external code files can be cached by the browser.

If you have a menu then changing ShortcutKeys property of the ToolStripMenuItem should do the trick.

If not, you could create one and set its visible property to false.

Your code is fine, but the problem is inside the batch file.

You have to show the content of the bat file, your problem is in the paths inside the bat file.

First use pkill or kill -9 <pid> to kill the process.

Then use following userdel command to delete user,

userdel -f cafe_fixer

According to userdel man page:

-f, --force

This option forces the removal of the user account, even if the user is still logged in. It also forces userdel to remove the user's home directory and mail spool, even if another user uses the same home directory or if the mail spool is not owned by the specified user. If USERGROUPS_ENAB is defined to yes in /etc/login.defs and if a group exists with the same name as the deleted user, then this group will be removed, even if it is still the primary group of another user.

Edit 1: (by @Ajedi32)

Note: This option (i.e. --force) is dangerous and may leave your system in an inconsistent state.

Edit 2: (by @socketpair)

In spite of the description about some files, this key allows removing the user while it is in use. Don't forget to chdir / before, because this command will also remove home directory.

If the pop-up's document is from a different domain, this is simply not possible.

Update April 2015: I was wrong about this: if you own both domains, you can use window.postMessage and the message event in pretty much all browsers that are relevant today.

If not, there's still no way you'll be able to make this work cross-browser without some help from the document being loaded into the pop-up. You need to be able to detect a change in the pop-up that occurs once it has loaded, which could be a variable that JavaScript in the pop-up page sets when it handles its own load event, or if you have some control of it you could add a call to a function in the opener.

You can do something like this to check if any mysql process is running or not:

ps aux | grep mysqld
ps aux | grep mysql

Then if it is running you can killall by using(depending on what all processes are running currently):

killall -9 mysql
killall -9 mysqld
killall -9 mysqld_safe    

Out of your comments to Mike Monkiewicz answer I suggest to use a simpler model: Use regular development branches, but use the squash option of the merge to get a single commit in your master branch:

git checkout -b bug1    # create the development branch
* hack hack hack *      # do some work
git commit
* hack hack hack *
git commit
* hack hack hack *
git commit
* hack hack hack *
git commit
git checkout master     # go back to the master branch
git merge --squash bug1 # merge the work back
git commit              # commit the merge (don't forget
                        #    to change the default commit message)
git branch -D bug1      # remove the development branch

The advantage of this procedure is that you can use the normal git work flow.

Set your Textbox value in a string like:

string MySTring = textBox1.Text;

Then replace your string. For example, replace "Text" with "Hex":

MyString = MyString.Replace("Text", "Hex");

Or for your problem (replace "," with ;) :

MyString = MyString.Replace(@""",""", ",");

Note: If you have "" in your string you have to use @ in the back of "", like:

@"","";

Adding even more simplicity of use to Jasper Bekkers' fantastic answer:

Set up once:

#define MAKE_ENUM(VAR) VAR,
#define MAKE_STRINGS(VAR) #VAR,
#define MAKE_ENUM_AND_STRINGS(source, enumName, enumStringName) \
    enum enumName { \
    source(MAKE_ENUM) \
    };\
const char* const enumStringName[] = { \
    source(MAKE_STRINGS) \
    };

Then, for usage:

#define SOME_ENUM(DO) \
    DO(Foo) \
    DO(Bar) \
    DO(Baz)
...
MAKE_ENUM_AND_STRINGS(SOME_ENUM, someEnum, someEnumNames)

UITextView does not have any methods which will be called when the user hits the return key. If you want the user to be able to add only one line of text, use a UITextField. Hitting the return and hiding the keyboard for a UITextView does not follow the interface guidelines.

Even then if you want to do this, implement the textView:shouldChangeTextInRange:replacementText: method of UITextViewDelegate and in that check if the replacement text is \n, hide the keyboard.

There might be other ways but I am not aware of any.

There are many different versions of mail around. When you go beyond mail -s subject to1@address1 to2@address2

• With some mailx implementations, e.g. from mailutils on Ubuntu or Debian's bsd-mailx, it's easy, because there's an option for that.

  mailx -a 'Content-Type: text/html' -s "Subject" to@address <test.html
  

• With the Heirloom mailx, there's no convenient way. One possibility to insert arbitrary headers is to set editheaders=1 and use an external editor (which can be a script).

  ## Prepare a temporary script that will serve as an editor.
  
  ## This script will be passed to ed.
  temp_script=$(mktemp)
  cat <<'EOF' >>"$temp_script"
  1a
  Content-Type: text/html
  .
  $r test.html
  w
  q
  EOF
  ## Call mailx, and tell it to invoke the editor script
  EDITOR="ed -s $temp_script" heirloom-mailx -S editheaders=1 -s "Subject" to@address <<EOF
  ~e
  .
  EOF
  rm -f "$temp_script"
  

• With a general POSIX mailx, I don't know how to get at headers.

If you're going to use any mail or mailx, keep in mind that

• This isn't portable even within a given Linux distribution. For example, both Ubuntu and Debian have several alternatives for mail and mailx.

• When composing a message, mail and mailx treats lines beginning with ~ as commands. If you pipe text into mail, you need to arrange for this text not to contain lines beginning with ~.

If you're going to install software anyway, you might as well install something more predictable than mail/Mail/mailx. For example, mutt. With Mutt, you can supply most headers in the input with the -H option, but not Content-Type, which needs to be set via a mutt option.

mutt -e 'set content_type=text/html' -s 'hello' 'to@address' <test.html

Or you can invoke sendmail directly. There are several versions of sendmail out there, but they all support sendmail -t to send a mail in the simplest fashion, reading the list of recipients from the mail. (I think they don't all support Bcc:.) On most systems, sendmail isn't in the usual $PATH, it's in /usr/sbin or /usr/lib.

cat <<'EOF' - test.html | /usr/sbin/sendmail -t
To: to@address
Subject: hello
Content-Type: text/html

EOF

With GCC 4.1.2, to print the whole of a std::vector<int> called myVector, do the following:

print *(myVector._M_impl._M_start)@myVector.size()

To print only the first N elements, do:

print *(myVector._M_impl._M_start)@N

Explanation

This is probably heavily dependent on your compiler version, but for GCC 4.1.2, the pointer to the internal array is:

myVector._M_impl._M_start 

And the GDB command to print N elements of an array starting at pointer P is:

print P@N

Or, in a short form (for a standard .gdbinit):

p P@N

when do you call timerReset()? Perhaps you get that error when trying to call it after setTimeout() has already done its thing?

wrap it in

if (window.myTimeout) { 
  clearTimeout(myTimeout);
  myTimeout = setTimeout("timerDone()", 1000 * 1440);
}

edit: Actually, upon further reflection, since you did mention jQuery (and yet don't have any actual jQuery code here... I wonder if you have this nested within some jQuery (like inside a $(document).ready(.. and this is a matter of variable scope. If so, try this:

window.message="Logged in";
window.myTimeout = setTimeout("timerDone()",1000 * 1440);
function timerDone()
{
    window.message="Logged out";   
}
function timerReset()
{


    clearTimeout(window.myTimeout);
    window.myTimeout = setTimeout("timerDone()", 1000 * 1440);
}

Quick comparison of timings in response to the post by Abbafei:

import timeit

def func1():
    phrase = 'Lucky Dog'
    return any(i in 'LD' for i in phrase)

def func2():
    phrase = 'Lucky Dog'
    if ('L' in phrase) or ('D' in phrase):
        return True
    else:
        return False

if __name__ == '__main__': 
    func1_time = timeit.timeit(func1, number=100000)
    func2_time = timeit.timeit(func2, number=100000)
    print('Func1 Time: {0}\nFunc2 Time: {1}'.format(func1_time, func2_time))

Output:

Func1 Time: 0.0737484362111
Func2 Time: 0.0125144964371

So the code is more compact with any, but faster with the conditional.

EDIT : TL;DR -- For long strings, if-then is still much faster than any!

I decided to compare the timing for a long random string based on some of the valid points raised in the comments:

# Tested in Python 2.7.14

import timeit
from string import ascii_letters
from random import choice

def create_random_string(length=1000):
    random_list = [choice(ascii_letters) for x in range(length)]
    return ''.join(random_list)

def function_using_any(phrase):
    return any(i in 'LD' for i in phrase)

def function_using_if_then(phrase):
    if ('L' in phrase) or ('D' in phrase):
        return True
    else:
        return False

if __name__ == '__main__':
    random_string = create_random_string(length=2000)
    func1_time = timeit.timeit(stmt="function_using_any(random_string)",
                               setup="from __main__ import function_using_any, random_string",
                               number=200000)
    func2_time = timeit.timeit(stmt="function_using_if_then(random_string)",
                               setup="from __main__ import function_using_if_then, random_string",
                               number=200000)
    print('Time for function using any: {0}\nTime for function using if-then: {1}'.format(func1_time, func2_time))

Output:

Time for function using any: 0.1342546
Time for function using if-then: 0.0201827

If-then is almost an order of magnitude faster than any!

  And

  private int productID;
  
  public int ProductID
  {
      get { return productID; }
      set { productID = value; }

  becomes

  public int ProductID { get; set; }
  

If the array contains integers, the value cannot be NULL. NULL can be used if the array contains pointers.

SomeClass* myArray[2];
myArray[0] = new SomeClass();
myArray[1] = NULL;

if (myArray[0] != NULL) { // this will be executed }
if (myArray[1] != NULL) { // this will NOT be executed }

As http://en.cppreference.com/w/cpp/types/NULL states, NULL is a null pointer constant!

You should return a reference to an existing object that isn't going away immediately, and where you don't intend any transfer of ownership.

Never return a reference to a local variable or some such, because it won't be there to be referenced.

You can return a reference to something independent of the function, which you don't expect the calling function to take the responsibility for deleting. This is the case for the typical operator[] function.

If you are creating something, you should return either a value or a pointer (regular or smart). You can return a value freely, since it's going into a variable or expression in the calling function. Never return a pointer to a local variable, since it will go away.

If your platform matrix supports Java 7 then you can use like below

List<List<String>> myList = new ArrayList<>();

If the use case is storing data in a collection then ECMAScript 6 provides the Map type.

It's only heavier to initialize.

Here is an example:

const map = new Map();
map.set(1, "One");
map.set(2, "Two");
map.set(3, "Three");

console.log("=== With Map ===");

for (const [key, value] of map) {
    console.log(`${key}: ${value} (${typeof(key)})`);
}

console.log("=== With Object ===");

const fakeMap = {
    1: "One",
    2: "Two",
    3: "Three"
};

for (const key in fakeMap) {
    console.log(`${key}: ${fakeMap[key]} (${typeof(key)})`);
}

Result:

=== With Map ===
1: One (number)
2: Two (number)
3: Three (number)
=== With Object ===
1: One (string)
2: Two (string)
3: Three (string)

You need the Business Intelligence Studio ..I've checked and my version of VS2008 Pro doesn't have them installed.

Have a look at this link:

Another solution is to use WMI.NET or Windows Management Instrumentation.

Using the .NET Framework namespace System.Management, you can automate administrative tasks using Windows Management Instrumentation (WMI).

Code Sample

using System.Management;
...
var processToRun = new[] { "notepad.exe" };
var connection = new ConnectionOptions();
connection.Username = "username";
connection.Password = "password";
var wmiScope = new ManagementScope(String.Format("\\\\{0}\\root\\cimv2", REMOTE_COMPUTER_NAME), connection);
var wmiProcess = new ManagementClass(wmiScope, new ManagementPath("Win32_Process"), new ObjectGetOptions());
wmiProcess.InvokeMethod("Create", processToRun);

If you have trouble with authentication, then check the DCOM configuration.

1. On the target machine, run dcomcnfg from the command prompt.
2. Expand Component Services\Computers\My Computer\DCOM Config
3. Find Windows Management Instruction, identified with GUID 8BC3F05E-D86B-11D0-A075-00C04FB68820 (you can see this in the details view).
4. Edit the properties and then add the username you are trying to login with under the permissions tab.
5. You may need to reboot the service or the entire machine.

NOTE: All paths used for the remote process need to be local to the target machine.

Index-based joins

TL;DR

There are a few options, some simpler than others depending on the use case.

1. DataFrame.merge with left_index and right_index (or left_on and right_on using names indexes)
   • supports inner/left/right/full
   • can only join two at a time
   • supports column-column, index-column, index-index joins
2. DataFrame.join (join on index)
   • supports inner/left (default)/right/full
   • can join multiple DataFrames at a time
   • supports index-index joins
3. pd.concat (joins on index)
   • supports inner/full (default)
   • can join multiple DataFrames at a time
   • supports index-index joins

Index to index joins

Setup & Basics

import pandas as pd
import numpy as np

np.random.seed([3, 14])
left = pd.DataFrame(data={'value': np.random.randn(4)}, 
                    index=['A', 'B', 'C', 'D'])    
right = pd.DataFrame(data={'value': np.random.randn(4)},  
                     index=['B', 'D', 'E', 'F'])
left.index.name = right.index.name = 'idxkey'

left
           value
idxkey          
A      -0.602923
B      -0.402655
C       0.302329
D      -0.524349

right
 
           value
idxkey          
B       0.543843
D       0.013135
E      -0.326498
F       1.385076

Typically, an inner join on index would look like this:

left.merge(right, left_index=True, right_index=True)

         value_x   value_y
idxkey                    
B      -0.402655  0.543843
D      -0.524349  0.013135

Other joins follow similar syntax.

Notable Alternatives

1. DataFrame.join defaults to joins on the index. DataFrame.join does a LEFT OUTER JOIN by default, so how='inner' is necessary here.

    left.join(right, how='inner', lsuffix='_x', rsuffix='_y')
   
             value_x   value_y
    idxkey                    
    B      -0.402655  0.543843
    D      -0.524349  0.013135
   

   Note that I needed to specify the lsuffix and rsuffix arguments since join would otherwise error out:

    left.join(right)
    ValueError: columns overlap but no suffix specified: Index(['value'], dtype='object')
   

   Since the column names are the same. This would not be a problem if they were differently named.

    left.rename(columns={'value':'leftvalue'}).join(right, how='inner')
   
            leftvalue     value
    idxkey                     
    B       -0.402655  0.543843
    D       -0.524349  0.013135
   

2. pd.concat joins on the index and can join two or more DataFrames at once. It does a full outer join by default, so how='inner' is required here..

    pd.concat([left, right], axis=1, sort=False, join='inner')
   
               value     value
    idxkey                    
    B      -0.402655  0.543843
    D      -0.524349  0.013135
   

   For more information on concat, see this post.

Index to Column joins

To perform an inner join using index of left, column of right, you will use DataFrame.merge a combination of left_index=True and right_on=....

right2 = right.reset_index().rename({'idxkey' : 'colkey'}, axis=1)
right2
 
  colkey     value
0      B  0.543843
1      D  0.013135
2      E -0.326498
3      F  1.385076

left.merge(right2, left_index=True, right_on='colkey')

    value_x colkey   value_y
0 -0.402655      B  0.543843
1 -0.524349      D  0.013135

Other joins follow a similar structure. Note that only merge can perform index to column joins. You can join on multiple columns, provided the number of index levels on the left equals the number of columns on the right.

join and concat are not capable of mixed merges. You will need to set the index as a pre-step using DataFrame.set_index.

Effectively using Named Index [pandas >= 0.23]

If your index is named, then from pandas >= 0.23, DataFrame.merge allows you to specify the index name to on (or left_on and right_on as necessary).

left.merge(right, on='idxkey')

         value_x   value_y
idxkey                    
B      -0.402655  0.543843
D      -0.524349  0.013135

For the previous example of merging with the index of left, column of right, you can use left_on with the index name of left:

left.merge(right2, left_on='idxkey', right_on='colkey')

    value_x colkey   value_y
0 -0.402655      B  0.543843
1 -0.524349      D  0.013135

You can use -

$isTouch = isset($variable);

It will return true if the $variable is defined. if the variable is not defined it will return false.

Note : Returns TRUE if var exists and has value other than NULL, FALSE otherwise.

If you want to check for false, 0 etc You can then use empty() -

$isTouch = empty($variable);

empty() works for -

• "" (an empty string)
• 0 (0 as an integer)
• 0.0 (0 as a float)
• "0" (0 as a string)
• NULL
• FALSE
• array() (an empty array)
• $var; (a variable declared, but without a value)

The pyaudio website has many examples that are pretty short and clear: http://people.csail.mit.edu/hubert/pyaudio/

Update 14th of December 2019 - Main example from the above linked website from 2017:

CHUNK = 1024

if len(sys.argv) < 2:
    print("Plays a wave file.\n\nUsage: %s filename.wav" % sys.argv[0])
    sys.exit(-1)

wf = wave.open(sys.argv[1], 'rb')

p = pyaudio.PyAudio()

                channels=wf.getnchannels(),
                rate=wf.getframerate(),
                output=True)

ThiefMaster's answer is 100% correct, although I came across a similar problem where I needed to fetch a property from a nested object (object within an object), so as an alternative to his answer, you can create a recursive solution that will allow you to define a nomenclature to grab any property, regardless of depth:

function fetchFromObject(obj, prop) {

    if(typeof obj === 'undefined') {
        return false;
    }

    var _index = prop.indexOf('.')
    if(_index > -1) {
        return fetchFromObject(obj[prop.substring(0, _index)], prop.substr(_index + 1));
    }

    return obj[prop];
}

Where your string reference to a given property ressembles property1.property2

I solved the issue removing gulp and installing gulp-cli again:

rm /usr/local/bin/gulp
npm install -g gulp-cli

You can't create tags with Dockerfiles but you can create multiple tags on your images via the command line.

Use this to list your image ids:

$ docker images

Then tag away:

$ docker tag 9f676bd305a4 ubuntu:13.10
$ docker tag 9f676bd305a4 ubuntu:saucy
$ docker tag eb601b8965b8 ubuntu:raring
...

Along with the many other reasons mentioned already, you could also point outh that hard-coding

sys.path.append(os.path.dirname(os.path.dirname(os.path.abspath(__file__))))

is brittle because it presumes the location of script.py -- it will only work if script.py is located in Project/package. It will break if a user decides to move/copy/symlink script.py (almost) anywhere else.

SUBSTRING ( MyColumn, 1 , 1 ) for the first character and SUBSTRING ( MyColumn, 1 , 2 ) for the first two.

You can use double quotes instead of single quotes:

theAnchorText = "I'm home";

Alternatively, escape the apostrophe:

theAnchorText = 'I\'m home';

The backslash tells JavaScript (this has nothing to do with jQuery, by the way) that the next character should be interpreted as "special". In this case, an apostrophe after a backslash means to use a literal apostrophe but not to end the string.

There are also other characters you can put after a backslash to indicate other special characters. For example, you can use \n for a new line, or \t for a tab.

i had problem to run it and i make some changes to run it with mp3 source. here is BackfrounSoundService.java file. consider that my mp3 file is in my sdcard in my phone .

public class BackgroundSoundService extends Service {
    private static final String TAG = null;
    MediaPlayer player;

    public IBinder onBind(Intent arg0) {

        return null;
    }

    @Override
    public void onCreate() {
        super.onCreate();
        Log.d("service", "onCreate");
        player = new MediaPlayer();
        try {
            player.setDataSource(Environment.getExternalStorageDirectory().getAbsolutePath() + "/your file.mp3");
        } catch (IOException e) {
            e.printStackTrace();
        }
        player.setLooping(true); // Set looping
        player.setVolume(100, 100);

    }

    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.d("service", "onStartCommand");
        try {
            player.prepare();
            player.start();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return 1;
    }

    public void onStart(Intent intent, int startId) {
        // TO DO
    }

    public IBinder onUnBind(Intent arg0) {
        // TO DO Auto-generated method
        return null;
    }

    public void onStop() {

    }

    public void onPause() {

    }

    @Override
    public void onDestroy() {
        player.stop();
        player.release();
    }

    @Override
    public void onLowMemory() {

    }
}

args contains the command-line arguments passed to the Java program upon invocation. For example, if I invoke the program like so:

$ java MyProg -f file.txt

Then args will be an array containing the strings "-f" and "file.txt".

use default js match() function:

if( element.attr('class') !== undefined && element.attr('class').match(/class1|class2|class3|class4|class5/) ) {
  console.log("match");
}

to use variables in regexp, use this:

var reg = new RegExp(variable, 'g');
$(this).match(reg);

by the way, this is the fastest way: http://jsperf.com/hasclass-vs-is-stackoverflow/22

import os.path

if os.path.isfile(filepath):
   print("File exists")

With inspiration from the Bob's answer, these extensions also support null value conversion and all primitive conversion back and fourth.

public static class ConversionExtensions
{
        public static object Convert(this object value, Type t)
        {
            Type underlyingType = Nullable.GetUnderlyingType(t);

            if (underlyingType != null && value == null)
            {
                return null;
            }
            Type basetype = underlyingType == null ? t : underlyingType;
            return System.Convert.ChangeType(value, basetype);
        }

        public static T Convert<T>(this object value)
        {
            return (T)value.Convert(typeof(T));
        }
}

Examples

            string stringValue = null;
            int? intResult = stringValue.Convert<int?>();

            int? intValue = null;
            var strResult = intValue.Convert<string>();

You missed single quote sign:

SELECT * 
FROM TABLENAME 
WHERE DateTime >= '12/04/2011 12:00:00 AM' AND DateTime <= '25/05/2011 3:53:04 AM'

Also, it is recommended to use ISO8601 format YYYY-MM-DDThh:mm:ss.nnn[ Z ], as this one will not depend on your server's local culture.

SELECT *
FROM TABLENAME 
WHERE 
    DateTime >= '2011-04-12T00:00:00.000' AND 
    DateTime <= '2011-05-25T03:53:04.000'

Query Builder:

DB::table(..)->select(..)->whereNotIn('book_price', [100,200])->get();

Eloquent:

SomeModel::select(..)->whereNotIn('book_price', [100,200])->get();

You have to use start and $NUL for this in Windows PowerShell:

Type in this command assuming mySum is the name of your application and 5 10 are command line arguments you are sending.

start .\mySum  5 10 > $NUL 2>&1

The start command will start a detached process, a similar effect to &. The /B option prevents start from opening a new terminal window if the program you are running is a console application. and NUL is Windows' equivalent of /dev/null. The 2>&1 at the end will redirect stderr to stdout, which will all go to NUL.

To solve this issue the first thing you need to do is to get the last version of composer :

curl -sS https://getcomposer.org/installer | php

I recommend you to move the composer.phar file to a global “bin” directoy, in my case (OS X) the path is:

mv composer.phar /usr/local/bin/composer.phar

than you need to create an alias file for an easy access

alias composer='/usr/local/bin/composer.phar'

If everything is ok, now it is time to verify our Composer version:

composer --version

Let's make composer great again.

For windows server I think u can use this:

<?php
echo exec('getmac');
?>

I had this same problem, using an old version of the route-me library. I "skipped" all the libraries, and the libraries inside of libraries (proj4), but I still had the same problem. Turns out that route-me and proj4 were installing public header files, even when the libraries were being skipped, which was messing it up in the same way! So I just went into the route-me and proj4 targets "Build Phases" tab, opened "Copy Headers", opened "Public", and dragged those headers from "Public" into "Project". Now they don't get installed in $(BUILD)/usr/local/include, and I'm able to make an ipa file from the archive!

I hope Apple fixes this horrible usability problem with XCode. It gives absolutely no indication of what's wrong, it just doesn't work. I hate dimmed out controls that don't tell you anything about why they're dimmed out. How about instead of ignoring clicks, the disabled controls could pop up a message telling you why the hell they're disabled when you click on them in frustration?

Just in case someone else encounters this problem. You need to call

window.location.reload()

And you cannot call this from a expression. If you want to call this from a click event you need to put this on a function:

(click)="realodPage()"

And simply define the function:

reloadPage() {
   window.location.reload();
}

If you are changing the route, it might not work because the click event seems to happen before the route changes. A very dirty solution is just to add a small delay

reloadPage() {
    setTimeout(()=>{
      window.location.reload();
    }, 100);
}

On Linux use below to test (it would replace the whitespaces with comma)

 sed 's/\s/,/g' /tmp/test.txt | head

later you can take the output into the file using below command:

sed 's/\s/,/g' /tmp/test.txt > /tmp/test_final.txt

PS: test is the file which you want to use

Also, you can use the ? operator to avoid having to use @if @else @endif syntax. Change:

@if (Input::old('title') == $key)
      <option value="{{ $key }}" selected>{{ $val }}</option>
@else
      <option value="{{ $key }}">{{ $val }}</option>
@endif

Simply to:

<option value="{{ $key }}" {{ (Input::old("title") == $key ? "selected":"") }}>{{ $val }}</option>

I was getting a cross domain permissions issue when trying to run the answer to this question so I went with:

function UrlExists(url) {
$('<img src="'+ url +'">').load(function() {
    return true;
}).bind('error', function() {
    return false;
});
}

It seems to work great, hope this helps someone!
