If you are looking for a way to it without SQL you should be able to use delete_all.

Post.delete_all

or with a criteria

Post.delete_all "person_id = 5 AND (category = 'Something' OR category = 'Else')"

See here for more information.

The records are deleted without loading them first which makes it very fast but will break functionality like counter cache that depends on rails code to be executed upon deletion.

Where A is your 2D array:

import numpy as np
A[np.isnan(A)] = 0

The function isnan produces a bool array indicating where the NaN values are. A boolean array can by used to index an array of the same shape. Think of it like a mask.

To run command as a system service on debian with sysv init:

Copy skeleton script and adapt it for your needs, probably all you have to do is to set some variables. Your script will inherit fine defaults from /lib/init/init-d-script, if something does not fits your needs - override it in your script. If something goes wrong you can see details in source /lib/init/init-d-script. Mandatory vars are DAEMON and NAME. Script will use start-stop-daemon to run your command, in START_ARGS you can define additional parameters of start-stop-daemon to use.

cp /etc/init.d/skeleton /etc/init.d/myservice
chmod +x /etc/init.d/myservice
nano /etc/init.d/myservice

/etc/init.d/myservice start
/etc/init.d/myservice stop

That is how I run some python stuff for my wikimedia wiki:

...
DESC="mediawiki articles converter"
DAEMON='/home/mss/pp/bin/nslave'
DAEMON_ARGS='--cachedir /home/mss/cache/'
NAME='nslave'
PIDFILE='/var/run/nslave.pid'
START_ARGS='--background --make-pidfile --remove-pidfile --chuid mss --chdir /home/mss/pp/bin'

export PATH="/home/mss/pp/bin:$PATH"

do_stop_cmd() {
    start-stop-daemon --stop --quiet --retry=TERM/30/KILL/5 \
        $STOP_ARGS \
        ${PIDFILE:+--pidfile ${PIDFILE}} --name $NAME
    RETVAL="$?"
    [ "$RETVAL" = 2 ] && return 2
    rm -f $PIDFILE
    return $RETVAL
}

Besides setting vars I had to override do_stop_cmd because of python substitutes the executable, so service did not stop properly.

Try running "~/anaconda3/bin/jupyter notebook" instead of "jupyter notebook". This resolved the problem for me. No more getting 'permission denied' error.

You cannot do that with the native confirm() as it is the browser’s method.

You have to create a plugin for a confirm box (or try one created by someone else). And they often look better, too.

1. You can create pipe inherited from PipeTransform base
2. Then implement transform method

Used in Angular 4 - it's working. Best way to format a date is a pipe.

Create your custom pipe like this:

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

@Pipe({
    name: 'dateFormat'
  })
  export class DateFormatPipe extends DatePipe implements PipeTransform {
    transform(value: any, args?: any): any {
       ///MMM/dd/yyyy 
       return super.transform(value, "MMM/dd/yyyy");
    }
  }

and it's used in a TypeScript class like this:

////my class////

export class MyComponent
{
  constructor(private _dateFormatPipe:DateFormatPipe)
  {
  }

  formatHereDate()
  {
     let myDate = this._dateFormatPipe.transform(new Date())//formatting current ///date here 
     //you can pass any date type variable 
  }
}

After you install the ftp server with sudo apt-get install vsftpd you will have to configure it. To enable write access you have to edit the /etc/vsftpd.conf file and uncomment the

#write_enable=YES

line, so it should read

write_enable=YES

Save the file and restart vsftpd with sudo service vsftpd restart.

For other configuration options consult this documentation or man vsftpd.conf

Here is a little utility class that I created:

import java.io.File;
import java.io.FilenameFilter;
import java.util.HashSet;
import java.util.Iterator;
import java.util.Set;

/**
 * Convenience utility to create a FilenameFilter, based on a list of extensions
 */
public class FileExtensionFilter implements FilenameFilter {
    private Set<String> exts = new HashSet<String>();

    /**
     * @param extensions
     *            a list of allowed extensions, without the dot, e.g.
     *            <code>"xml","html","rss"</code>
     */
    public FileExtensionFilter(String... extensions) {
        for (String ext : extensions) {
            exts.add("." + ext.toLowerCase().trim());
        }
    }

    public boolean accept(File dir, String name) {
        final Iterator<String> extList = exts.iterator();
        while (extList.hasNext()) {
            if (name.toLowerCase().endsWith(extList.next())) {
                return true;
            }
        }
        return false;
    }
}

Usage:

       String[] files = new File("myfile").list(new FileExtensionFilter("pdf", "zip"));

try this

 $("#vinanghinguyen_images_bbocde").attr("value", ""); 

There are multiple ways to create an array in shell.

ARR[0]="ABC"
ARR[1]="BCD"
echo ${ARR[*]}

${ARR[*]} prints all elements in the array.

Second way is:

ARR=("A" "B" "C" "D" 5 7 "J")
echo ${#ARR[@]}
echo ${ARR[0]}

${#ARR[@]} is used to count length of the array.

have at look at the static methods DateTime.Parse() and DateTime.TryParse(). They will allow you to pass in your date string and a format string, and get a DateTime object in return.

I know this question is old, but now we can achieve the same result without WRITE_EXTERNAL_STORAGE permission. Instead of we can use File provider.

private fun storeBitmap(bitmap: Bitmap, file: File){
        requireContext().getUriForFile(file)?.run {
            requireContext().contentResolver.openOutputStream(this)?.run {
                bitmap.compress(Bitmap.CompressFormat.JPEG, 100, this)
                close()
            }
        }
    }

How to retrieve file from provider ?

fun Context.getUriForFile(file: File): Uri? {
        return FileProvider.getUriForFile(
            this,
            "$packageName.fileprovider",
            file
        )
    }

Also do not forget register your provider in Android manifest

<provider
        android:name="androidx.core.content.FileProvider"
        android:authorities="${applicationId}.fileprovider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/file_paths"/>
    </provider>

It looks like a common gaps-and-islands problem. The difference between two sequences of row numbers rn1 and rn2 give the "group" number.

Run this query CTE-by-CTE and examine intermediate results to see how it works.

Sample data

I expanded sample data from the question a little.

DECLARE @Source TABLE
(
    EmployeeID int,
    DateStarted date,
    DepartmentID int
)

INSERT INTO @Source

Query for SQL Server 2008

There is no LEAD function in SQL Server 2008, so I had to use self-join via OUTER APPLY to get the value of the "next" row for the DateEnd.

Laravel has the Carbon dependency attached to it.

Carbon::now(), include the Carbon\Carbon namespace if necessary.

Edit (usage and docs)

Say I want to retrieve the date and time and output it as a string.

$mytime = Carbon\Carbon::now();
echo $mytime->toDateTimeString();

This will output in the usual format of Y-m-d H:i:s, there are many pre-created formats and you will unlikely need to mess with PHP date time strings again with Carbon.

Documentation: https://github.com/briannesbitt/Carbon

String formats for Carbon: http://carbon.nesbot.com/docs/#api-formatting

For the official CLI client "psql" see here. And "pgAdmin3" 1.10 (still in beta) has "pgScript".

This also happened to me on Ubuntu 16.04 using the nvidia-348 package (latest nvidia version on Ubuntu 16.04).

However I could resolve the problem by installing nvidia-390 through the Proprietary GPU Drivers PPA.

So a solution to the described problem on Ubuntu 16.04 is doing this:

• sudo add-apt-repository ppa:graphics-drivers/ppa
• sudo apt-get update
• sudo apt-get install nvidia-390

Note: This guide assumes a clean Ubuntu install. If you have previous drivers installed a reboot migh be needed to reload all the kernel modules.

Once an instance has been started, there is no way to change the keypair associated with the instance at a meta data level, but you can change what ssh key you use to connect to the instance.

There is a startup process on most AMIs that downloads the public ssh key and installs it in a .ssh/authorized_keys file so that you can ssh in as that user using the corresponding private ssh key.

If you want to change what ssh key you use to access an instance, you will want to edit the authorized_keys file on the instance itself and convert to your new ssh public key.

The authorized_keys file is under the .ssh subdirectory under the home directory of the user you are logging in as. Depending on the AMI you are running, it might be in one of:

/home/ec2-user/.ssh/authorized_keys
/home/ubuntu/.ssh/authorized_keys
/root/.ssh/authorized_keys

After editing an authorized_keys file, always use a different terminal to confirm that you are able to ssh in to the instance before you disconnect from the session you are using to edit the file. You don't want to make a mistake and lock yourself out of the instance entirely.

While you're thinking about ssh keypairs on EC2, I recommend uploading your own personal ssh public key to EC2 instead of having Amazon generate the keypair for you.

Here's an article I wrote about this:

Uploading Personal ssh Keys to Amazon EC2
http://alestic.com/2010/10/ec2-ssh-keys

This would only apply to new instances you run.

In query where you are passing query parameters, typecast parameter to an integer

e.g. in the case of PostgreSQL, it might be

where table_name.column_name_with_integer_type = (:named_parameter_of_character_type)::integer

::integer will convert the parameter value into an integer.

Possibly an easier way?

Let's say justPrices is mixed up in terms of value, so you don't know where the smallest value is.

justPrices[0] = 4.5
justPrices[1] = 9.9
justPrices[2] = 1.5

Use sort.

justPrices.sort();

It would then put them in order for you. (Can also be done alphabetically.) The array then would be put in ascending order.

justPrices[0] = 1.5
justPrices[1] = 4.5
justPrices[2] = 9.9

You can then easily grab by the first index.

justPrices[0]

I find this is a bit more useful than what's proposed above because what if you need the lowest 3 numbers as an example? You can also switch which order they're arranged, more info at http://www.w3schools.com/jsref/jsref_sort.asp

Better to use Request.Url.OriginalString than Request.Url.ToString() (according to MSDN)

Just use the beef class:

public <T> T beefmarshal( Class<beef> beefClass, InputBeef inputBeef )
     throws JAXBException {
     String packageName = docClass.getPackage().getBeef();
     JAXBContext beef = JAXBContext.newInstance( packageName );
     Unmarshaller u = beef.createBeef();
     JAXBElement<T> doc = (JAXBElement<T>)u.beefmarshal( inputBeef );
     return doc.getBeef();
}

One option is to use a numbers/tally table to drive an iterative process via a pseudo-set based query.

The general idea of char replacement can be demonstrated with a simple character map table approach:

create table charMap (srcChar char(1), replaceChar char(1))
insert charMap values ('a', 'z')
insert charMap values ('b', 'y')


create table testChar(srcChar char(1))
insert testChar values ('1')
insert testChar values ('a')
insert testChar values ('2')
insert testChar values ('b')

select 
coalesce(charMap.replaceChar, testChar.srcChar) as charData
from testChar left join charMap on testChar.srcChar = charMap.srcChar

Then you can bring in the tally table approach to do the lookup on each character position in the string.

create table tally (i int)
declare @i int
set @i = 1
while @i <= 256 begin
    insert tally values (@i)
    set @i = @i + 1
end

create table testData (testString char(10))
insert testData values ('123a456')
insert testData values ('123ab456')
insert testData values ('123b456')

select
    i,
    SUBSTRING(testString, i, 1) as srcChar,
    coalesce(charMap.replaceChar, SUBSTRING(testString, i, 1)) as charData
from testData cross join tally
    left join charMap on SUBSTRING(testString, i, 1) = charMap.srcChar
where i <= LEN(testString)

You can do it like this:

 var myApp = angular.module('myApp', [])
  .controller('Ctrl', ['$scope', function($scope) {
     $scope.aaa = 3432
 }])
 .directive('test', function () {
    return {
       link: function (scope, elm, attr) {
           var look = elm.children('#findme').addClass("addedclass");
           console.log(look);
        }
   };
});

<div ng-app="myApp" ng-controller="Ctrl">
   <div test>TEST Div
      <div id="findme">{{aaa}}</div>
   </div>
</div>

In my case, migrating a Spring 3.1 app up to 3.2.7, my solution was similar to Matthias's but a bit different -- thus why I'm documenting it here:

In my POM I found this dependency and changed it from 6.0 to 7.0:

    <dependency>
        <groupId>javax</groupId>
        <artifactId>javaee-web-api</artifactId>
        <version>7.0</version>
        <scope>provided</scope>
    </dependency>

Then later in the POM I upgraded this plugin from 6.0 to 7.0:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-dependency-plugin</artifactId>
            <version>2.1</version>
            <executions>
                <execution>

                    <configuration>
                        ...
                        <artifactItems>
                            <artifactItem>

                            </artifactItem>
                        </artifactItems>
                    </configuration>

            </executions>

Public inheritance models an IS-A relationship. With

class B {};
class D : public B {};

every D is a B.

Private inheritance models an IS-IMPLEMENTED-USING relationship (or whatever that's called). With

class B {};
class D : private B {};

a D is not a B, but every D uses its B in its implementation. Private inheritance can always be eliminated by using containment instead:

class B {};
class D {
  private: 
    B b_;
};

This D, too, can be implemented using B, in this case using its b_. Containment is a less tight coupling between types than inheritance, so in general it should be preferred. Sometimes using containment instead of private inheritance is not as convenient as private inheritance. Often that's a lame excuse for being lazy.

I don't think anyone knows what protected inheritance models. At least I haven't seen any convincing explanation yet.

Tables work differently; sometimes counter-intuitively.

The solution is to use width on the table cells instead of max-width.

Although it may sound like in that case the cells won't shrink below the given width, they will actually.
with no restrictions on c, if you give the table a width of 70px, the widths of a, b and c will come out as 16, 42 and 12 pixels, respectively.
With a table width of 400 pixels, they behave like you say you expect in your grid above.
Only when you try to give the table too small a size (smaller than a.min+b.min+the content of C) will it fail: then the table itself will be wider than specified.

I made a snippet based on your fiddle, in which I removed all the borders and paddings and border-spacing, so you can measure the widths more accurately.

table {_x000D_
  width: 70px;_x000D_
}_x000D_
_x000D_
table, tbody, tr, td {_x000D_
  margin: 0;_x000D_
  padding: 0;_x000D_
  border: 0;_x000D_
  border-spacing: 0;_x000D_
}_x000D_
_x000D_
.a, .c {_x000D_
  background-color: red;_x000D_
}_x000D_
_x000D_
.b {_x000D_
  background-color: #F77;_x000D_
}_x000D_
_x000D_
.a {_x000D_
  min-width: 10px;_x000D_

  max-width: 45px;_x000D_
}_x000D_
_x000D_
.c {}

<table>_x000D_
  <tr>_x000D_
    <td class="a">A</td>_x000D_
    <td class="b">B</td>_x000D_

I suggest to use a CSS class called clickbox and activate it with jQuery:

$(".clickbox").click(function(){
     window.location=$(this).find("a").attr("href"); 
     return false;
 });

Now the only thing you have to do is mark your div as clickable and provide a link:

<div id="logo" class="clickbox"><a href="index.php"></a></div>

Plus a CSS style to change the mouse cursor:

.clickbox {
    cursor: pointer;
}

Easy, isn't it?

I would suggest using the strip_tags method.

df.drop(labels=df[df.index % 3 != 0].index, axis=0) #  every 3rd row (mod 3)

requests does not handle parsing XML responses, no. XML responses are much more complex in nature than JSON responses, how you'd serialize XML data into Python structures is not nearly as straightforward.

Python comes with built-in XML parsers. I recommend you use the ElementTree API:

import requests
from xml.etree import ElementTree

response = requests.get(url)

tree = ElementTree.fromstring(response.content)

or, if the response is particularly large, use an incremental approach:

    response = requests.get(url, stream=True)
    # if the server sent a Gzip or Deflate compressed response, decompress
    # as we read the raw stream:
    response.raw.decode_content = True

    events = ElementTree.iterparse(response.raw)
    for event, elem in events:
        # do something with `elem`

The external lxml project builds on the same API to give you more features and power still.

If you are logged in from the console, this will do the job in the latest heroku toolbelt,

heroku pg:reset --confirm database-name

I hit the same issue,and discovered the error message gives misleading variable names. Try setting the following (singular instead of plural):

PYTHON_INCLUDE_DIR=/usr/include/python2.7 
PYTHON_LIBRARY=/usr/lib/python2.7/config/libpython2.7.so

The (plural) variables you see error messages about are values that the PythonLibs sets up when it is initialised correctly.

Ok the magic was in this line that I apparently missed when installing was:

$ sudo apt-get install mongodb-10gen=2.4.6

And the full process as described here http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/ is

$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10
$ echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list
$ sudo apt-get update
$ sudo apt-get install mongodb-10gen
$ sudo apt-get install mongodb-10gen=2.2.3
$ echo "mongodb-10gen hold" | sudo dpkg --set-selections
$ sudo service mongodb start

$ mongod --version
db version v2.4.6
Wed Oct 16 12:21:39.938 git version: b9925db5eac369d77a3a5f5d98a145eaaacd9673

IMPORTANT: Make sure you change 2.4.6 to the latest version (or whatever you want to install). Find the latest version number here http://www.mongodb.org/downloads

I kind of like this method which I think covers all the bases:

const matches = str.match(/aeiou/gi];
return matches ? matches.length : 0;

This link describes how you can add a progress event listener to the xhr object using jquery.

$.ajax({
    xhr: function() {
        var xhr = new window.XMLHttpRequest();

        // Upload progress
        xhr.upload.addEventListener("progress", function(evt){
            if (evt.lengthComputable) {
                var percentComplete = evt.loaded / evt.total;
                //Do something with upload progress
                console.log(percentComplete);
            }
       }, false);
       
       // Download progress
       xhr.addEventListener("progress", function(evt){
           if (evt.lengthComputable) {
               var percentComplete = evt.loaded / evt.total;
               // Do something with download progress
               console.log(percentComplete);
           }
       }, false);
       
       return xhr;
    },
    type: 'POST',
    url: "/",
    data: {},
    success: function(data){
        // Do something success-ish
    }
});

Faced similar issue. I tried installing mysql-python using pip, but it failed due to gcc dependency errors.

The solution that worked for me

conda install mysql-python

Please note that I already had anaconda installed, which didn't had gcc dependency.

If you mark your entity with @DynamicInsert e.g.

@Entity
@DynamicInsert
@Table(name = "TABLE_NAME")
public class ClassName implements Serializable  {

Hibernate will generate SQL without null values. Then the database will insert its own default value. This does have performance implications See [Dynamic Insert][1].

In windows 7, you may have to edit this file

C:\Users\<UserName>\AppData\Roaming\Subversion\servers

[global]
http-proxy-host = ip.add.re.ss
http-proxy-port = 3128

These instructions explain how to install a python2 and python3 kernel in separate virtual environments for non-anaconda users. If you are using anaconda, please find my other answer for a solution directly tailored to anaconda.

I assume that you already have jupyter notebook installed.

First make sure that you have a python2 and a python3 interpreter with pip available.

On ubuntu you would install these by:

sudo apt-get install python-dev python3-dev python-pip python3-pip

Next prepare and register the kernel environments

python -m pip install virtualenv --user

# configure python2 kernel
python -m virtualenv -p python2 ~/py2_kernel
source ~/py2_kernel/bin/activate
python -m pip install ipykernel
ipython kernel install --name py2 --user
deactivate

# configure python3 kernel
python -m virtualenv -p python3 ~/py3_kernel
source ~/py3_kernel/bin/activate
python -m pip install ipykernel
ipython kernel install --name py3 --user
deactivate

To make things easier, you may want to add shell aliases for the activation command to your shell config file. Depending on the system and shell you use, this can be e.g. ~/.bashrc, ~/.bash_profile or ~/.zshrc

alias kernel2='source ~/py2_kernel/bin/activate'
alias kernel3='source ~/py3_kernel/bin/activate'

After restarting your shell, you can now install new packages after activating the environment you want to use.

kernel2
python -m pip install <pkg-name>
deactivate

or

kernel3
python -m pip install <pkg-name>
deactivate

With Postgres 9.3+, just use the -> operator. For example,

SELECT data->'images'->'thumbnail'->'url' AS thumb FROM instagram;

see http://clarkdave.net/2013/06/what-can-you-do-with-postgresql-and-json/ for some nice examples and a tutorial.

No need to write your own as setattr() and getattr() already exist.

The advantage of class objects probably comes into play in class definition and inheritance.

This answer might not be 100% relevant to the question. But it does address the problem. I found this simple way of achieving this requirement. Code goes below:

<a href="@Url.Action("Display", "Customer")?custId={{cust.Id}}"></a>

In the above example {{cust.Id}} is an AngularJS variable. However one can replace it with a JavaScript variable.

I haven't tried passing multiple variables using this method but I'm hopeful that also can be appended to the Url if required.

Negative top margins can achieve this effect, but they would need to be customized for each page. For instance, this markup...

<div class="product">
<h2>Greatest Product Ever</h2>
<p class="desc">This paragraph appears in the source code directly after the heading and will appear in the search results.</p>
<p class="sidenote">Note: This information appears in HTML after the product description appearing below.</p>
</div>

...and this CSS...

.product { width: 400px; }
.desc { margin-top: 5em; }
.sidenote { margin-top: -7em; }

...would allow you to pull the second paragraph above the first.

Of course, you'll have to manually tweak your CSS for different description lengths so that the intro paragraph jumps up the appropriate amount, but if you have limited control over the other parts and full control over markup and CSS then this might be an option.

You can set it in the config as others have said, or you can set in on an individual instance of the serializer like:

var js = new JavaScriptSerializer() { MaxJsonLength = int.MaxValue };

While the git fetch command will fetch down all the changes on the server that you don’t have yet, it will not modify your working directory at all. It will simply get the data for you and let you merge it yourself. However, there is a command called git pull which is essentially a git fetch immediately followed by a git merge in most cases.

When Object variables are initially used in a language like Java, they have absolutely no value at all - not zero, but literally no value - that is null

For instance: String s;

If you were to use s, it would actually have a value of null, because it holds absolute nothing.

An empty string, however, is a value - it is a string of no characters.

String s; //Inits to null
String a =""; //A blank string

Null is essentially 'nothing' - it's the default 'value' (to use the term loosely) that Java assigns to any Object variable that was not initialized.

Null isn't really a value - and as such, doesn't have properties. So, calling anything that is meant to return a value - such as .length(), will invariably return an error, because 'nothing' cannot have properties.

To go into more depth, by creating s1 = ""; you are initializing an object, which can have properties, and takes up relevant space in memory. By using s2; you are designating that variable name to be a String, but are not actually assigning any value at that point.

The options discussed above won't work because they are not part of the CSS specification (it is jQuery extension). Having spent 2-3 days digging around for information, I found that the only way to select the Text of the selected option from the drop down is:

{ $("select", id:"Some_ID").find("option[selected='selected']")}

Refer to additional notes below: Because :selected is a jQuery extension and not part of the CSS specification, queries using :selected cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. To achieve the best performance when using :selected to select elements, first select the elements using a pure CSS selector, then use .filter(":selected"). (copied from: http://api.jquery.com/selected-selector/)

You can use this one for return type of generic list:

public string ListType<T>(T value)
{
    var valueType = value.GetType().GenericTypeArguments[0].FullName;
    return valueType;
}

Problem was my package name. It MUST be "com.outbottle" (then config/controllers/model/etc) for it to work. As you can see above, I used Maven (for the first time), Spring, 1.8 JDK and nearly had a stroke debugging this issue. All running on Glassfish (Tomcat is ok too for the above pom config). That said, I'm all happy with myself now and know Maven and Spring much better for the next step of my Spring learning curve. Hoping this helps you also!

All else being equal, the best solution is one that clearly expresses your intent. So:

int totalSeconds = 453;
int minutes = totalSeconds / 60;
int remainingSeconds = totalSeconds % 60;

is probably the best of the three options you presented. As noted in other answers however, the div method will calculate both values for you at once.

To use Infinity, you can use Double which supports Infinity: -

    System.out.println(Double.POSITIVE_INFINITY);
    System.out.println(Double.POSITIVE_INFINITY * -1);
    System.out.println(Double.NEGATIVE_INFINITY);

    System.out.println(Double.POSITIVE_INFINITY - Double.NEGATIVE_INFINITY);
    System.out.println(Double.POSITIVE_INFINITY - Double.POSITIVE_INFINITY);

OUTPUT: -

Infinity
-Infinity
-Infinity

Infinity 
NaN

Have you thought about using mouseOver and mouseOut to simulate this. Also look into mouseEnter and mouseLeave

Added a test page - to color SVG via Filter settings:

Took the idea from: https://blog.union.io/code/2017/08/10/img-svg-fill/

1. Log into on your Server/PC with administrator account

2. Log into SQL Server Management Studio as "Windows Authentication"

3. Click Security -> Logins -> choose your -> right click then choose Properties or Double click -> click Server Roles -> then checklist 'dbcreator' and 'sysadmin' then click the OK button.

4. Refresh your databases.

Now, you can create new database.

I was facing the same problem, but what I did not realise is that I did not have the MySQL Server installed. You must simply install the MySQL Server.

In order to install the MySQL server, you must run the "MySql Installer" and then press the "Add" button and then choose the "MySQL Server" in the tree.

After doing that, run you workbench again and you'll notice that there'll already be a connection configured. Hopefully, you'll be able to create a new connection or as many connections as you want.

you can store your array using group_Concat like that

 INSERT into Table1 (fruits)  (SELECT GROUP_CONCAT(fruit_name) from table2)
 WHERE ..... //your clause here

HERE an example in fiddle

For Asp.net Core 2

ViewContext.ModelState["id"].AttemptedValue

As noted in the comments, this only works AFTER you've DataBound your repeater.

To find a control in the header:

lblControl = repeater1.Controls[0].Controls[0].FindControl("lblControl");

To find a control in the footer:

lblControl = repeater1.Controls[repeater1.Controls.Count - 1].Controls[0].FindControl("lblControl");

With extension methods

public static class RepeaterExtensionMethods
{
    public static Control FindControlInHeader(this Repeater repeater, string controlName)
    {
        return repeater.Controls[0].Controls[0].FindControl(controlName);
    }

    public static Control FindControlInFooter(this Repeater repeater, string controlName)
    {
        return repeater.Controls[repeater.Controls.Count - 1].Controls[0].FindControl(controlName);
    }
}

With your code, the vue.js is trying to access the moment() method from its scope.

Hence you should use a method like this:

methods: {
  moment: function () {
    return moment();
  }
},

If you want to pass a date to the moment.js, I suggest to use filters:

filters: {
  moment: function (date) {
    return moment(date).format('MMMM Do YYYY, h:mm:ss a');
  }
}

<span>{{ date | moment }}</span>

In this case, your test.js will not run, because you're loading it before jQuery. put it after jQuery:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script src="http://code.jquery.com/ui/1.9.2/jquery-ui.js"></script>
<script type="text/javascript" src="test.js"></script>

The problem is the tv.setText(text). The variable tv is probably null and you call the setText method on that null, which you can't. My guess that the problem is on the findViewById method, but it's not here, so I can't tell more, without the code.

Here is a working solution:

Instead of setting the spinner's OnClickListener, we are setting OnTouchListener and OnKeyListener.

spinner.setOnTouchListener(Spinner_OnTouch);
spinner.setOnKeyListener(Spinner_OnKey);

and the listeners:

private View.OnTouchListener Spinner_OnTouch = new View.OnTouchListener() {
    public boolean onTouch(View v, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_UP) {
            doWhatYouWantHere();
        }
        return true;
    }
};
private static View.OnKeyListener Spinner_OnKey = new View.OnKeyListener() {
    public boolean onKey(View v, int keyCode, KeyEvent event) {
        if (keyCode == KeyEvent.KEYCODE_DPAD_CENTER) {
            doWhatYouWantHere();
            return true;
        } else {
            return false;
        }
    }
};

try using the permission of WRITE_EXTERNAL_STORAGE You should use that whether there is an external card or not.

This works well for me:

path = Environment.getExternalStoragePublicDirectory(
                Environment.DIRECTORY_MOVIES);
File file = new File(path, "/" + fname);

and places my files in the appropriate folder

As others have mentioned, Environment.NewLine returns a platform-specific string for beginning a new line, which should be:

• "\r\n" (\u000D\u000A) for Windows
• "\n" (\u000A) for Unix
• "\r" (\u000D) for Mac (if such implementation existed)

Note that when writing to the console, Environment.NewLine is not strictly necessary. The console stream will translate "\n" to the appropriate new-line sequence, if necessary.

Facebook uses what's called the Open Graph Protocol to decide what things to display when you share a link. The OGP looks at your page and tries to decide what content to show. We can lend a hand and actually tell Facebook what to take from our page.

The way we do that is with og:meta tags.

The tags look something like this -

  <meta property="og:title" content="Stuffed Cookies" />
  <meta property="og:image" content="http://fbwerks.com:8000/zhen/cookie.jpg" />
  <meta property="og:description" content="The Turducken of Cookies" />
  <meta property="og:url" content="http://fbwerks.com:8000/zhen/cookie.html">

You'll need to place these or similar meta tags in the <head> of your HTML file. Don't forget to substitute the values for your own!

For more information you can read all about how Facebook uses these meta tags in their documentation. Here is one of the tutorials from there - https://developers.facebook.com/docs/opengraph/tutorial/

Facebook gives us a great little tool to help us when dealing with these meta tags - you can use the Debugger to see how Facebook sees your URL, and it'll even tell you if there are problems with it.

One thing to note here is that every time you make a change to the meta tags, you'll need to feed the URL through the Debugger again so that Facebook will clear all the data that is cached on their servers about your URL.

Adding a bit to mitigate the confusion here. Even though Darren Davies' (accepted) answer is more straight forward, I think Andrei's answer is a better approach for MVC applications.

The answer from Andrei means that you can use HttpContext just as you would use System.Web.HttpContext.Current. For example, if you want to do this:

System.Web.HttpContext.Current.User.Identity.Name

you should instead do this:

HttpContext.User.Identity.Name

Both achieve the same result, but (again) in terms of MVC, the latter is more recommended.

Another good and also straight forward information regarding this matter can be found here: Difference between HttpContext.Current and Controller.Context in MVC ASP.NET.

Only CSS 3 supports that,

background-size: 200px 50px;

But I would edit the image itself, so that the user needs to load less, and it might look better than a shrunken image without antialiasing.

The documentation states several ways to do this.

If you want to replace the default ObjectMapper completely, define a @Bean of that type and mark it as @Primary.

Defining a @Bean of type Jackson2ObjectMapperBuilder will allow you to customize both default ObjectMapper and XmlMapper (used in MappingJackson2HttpMessageConverter and MappingJackson2XmlHttpMessageConverter respectively).

It's built in Eclipse since ages. Which Eclipse version are you using? How were you trying to create a new JUnit test case? It should be File > New > Other > Java - JUnit - JUnit Test Case (you can eventually enter Filter text "junit").

Encoding.ASCII.GetString(buf);

I've recently had to use eval to force multiple brace expansions to be evaluated in the order I needed. Bash does multiple brace expansions from left to right, so

xargs -I_ cat _/{11..15}/{8..5}.jpg

expands to

xargs -I_ cat _/11/8.jpg _/11/7.jpg _/11/6.jpg _/11/5.jpg _/12/8.jpg _/12/7.jpg _/12/6.jpg _/12/5.jpg _/13/8.jpg _/13/7.jpg _/13/6.jpg _/13/5.jpg _/14/8.jpg _/14/7.jpg _/14/6.jpg _/14/5.jpg _/15/8.jpg _/15/7.jpg _/15/6.jpg _/15/5.jpg

but I needed the second brace expansion done first, yielding

xargs -I_ cat _/11/8.jpg _/12/8.jpg _/13/8.jpg _/14/8.jpg _/15/8.jpg _/11/7.jpg _/12/7.jpg _/13/7.jpg _/14/7.jpg _/15/7.jpg _/11/6.jpg _/12/6.jpg _/13/6.jpg _/14/6.jpg _/15/6.jpg _/11/5.jpg _/12/5.jpg _/13/5.jpg _/14/5.jpg _/15/5.jpg

The best I could come up with to do that was

xargs -I_ cat $(eval echo _/'{11..15}'/{8..5}.jpg)

This works because the single quotes protect the first set of braces from expansion during the parsing of the eval command line, leaving them to be expanded by the subshell invoked by eval.

There may be some cunning scheme involving nested brace expansions that allows this to happen in one step, but if there is I'm too old and stupid to see it.

This is also working both the filter and normal list. The first thing to create a new filter for the sum of all values from the list, and also given solution for a sum of the total quantity. In details code check it fiddler link.

angular.module("sampleApp", [])
        .filter('sumOfValue', function () {
        return function (data, key) {        
            if (angular.isUndefined(data) || angular.isUndefined(key))
                return 0;        
            var sum = 0;        
            angular.forEach(data,function(value){
                sum = sum + parseInt(value[key], 10);
            });        
            return sum;
        }
    }).filter('totalSumPriceQty', function () {
        return function (data, key1, key2) {        
            if (angular.isUndefined(data) || angular.isUndefined(key1)  || angular.isUndefined(key2)) 
                return 0;        
            var sum = 0;
            angular.forEach(data,function(value){
                sum = sum + (parseInt(value[key1], 10) * parseInt(value[key2], 10));
            });
            return sum;
        }
    }).controller("sampleController", function ($scope) {
        $scope.items = [

I had same issue using different dependancy what helped me is to set scope to compile.

Ansible has a version_compare filter since 1.6. You can do something like below in when conditional:

when: ansible_distribution_version | version_compare('12.04', '>=')

This will give you support for major & minor versions comparisons and you can compare versions using operators like:

<, lt, <=, le, >, gt, >=, ge, ==, =, eq, !=, <>, ne

You can find more information about this here: Ansible - Version comparison filters

Otherwise if you have really simple case you can use what @ProfHase85 suggested

If sounds like the type ACTInterface is not public, but is using the default accessibility of either internal (if it is top-level) or private (if it is nested in another type).

Giving the type the public modifier would fix it.

Another approach is to make both the type and the method internal, if that is your intent.

The issue is not the accessibility of the field (oActInterface), but rather of the type ACTInterface itself.

On newer versions of OS X you should find ALL JREs (and JDKs) under

/Library/Java/JavaVirtualMachines/

/System/Library/Java/JavaVirtualMachines/

the old path

/System/Library/Frameworks/JavaVM.framework/

has been deprecated.

Here is the official deprecation note:

Reformat affects the whole source code and may rebreak your lines, while Correct Indentation only affects the whitespace at the beginning of the lines.

The most important concern about private methods and attributes is to tell developers not to call it outside the class and this is encapsulation. one may misunderstand security from encapsulation. when one deliberately uses syntax like that(bellow) you mentioned, you do not want encapsulation.

obj._MyClass__myPrivateMethod()

I have migrated from C# and at first it was weird for me too but after a while I came to the idea that only the way that Python code designers think about OOP is different.

If your string is null, calls like this should throw a NullReferenceException:

myString.equals(null)

But anyway, I think a method like this is what you want:

public static class StringUtils
{
    public static bool isNullOrEmpty(String myString)
    {
         return myString == null || "".equals(myString);
    }
}

Then in your code, you can do things like this:

if (!StringUtils.isNullOrEmpty(myString))
{
    doSomething();
}

I agree with Laura and the SimpleDateFormat which is the best way to manage Dates in java. You can set the pattern and the locale. Plus you can have a look at this wikipedia article about Date in the world -there are not so many different ways to use it; typically USA / China / rest of the world -

The issue is because of a bad query the time to executing query is taking more than 60 seconds or a Lock on the Table

The issue looks like a deadlock is occurring; we have queries which are blocking the queries to complete in time. The default timeout for a query is 60 secs and beyond that we will have the SQLException for timeout.

Please check the SQL Server logs for deadlocks. The other way to solve the issue to to increase the Timeout on the Command Object (Temp Solution).

you can try StringIO or cStringIO

If disk space space is not an issue, this could also be a very easy thing to do:

mkdir backup
cp -r ./* backup
tar -zcvf backup.tar.gz ./backup

Be sure that android:debuggable="true" is set in the application tag of your manifest file, and then:

1. Plug your phone into your computer and enable USB debugging on the phone
2. Open eclipse and a workspace containing the code for your app
3. In Eclipse, go to Window->Show View->Devices
4. Look at the Devices view which should now be visible, you should see your device listed
5. If your device isn't listed, you'll have to track down the ADB drivers for your phone before continuing
6. If you want to step through code, set a breakpoint somewhere in your app
7. Open the app on your phone
8. In the Devices view, expand the entry for your phone if it isn't already expanded, and look for your app's package name.
9. Click on the package name, and in the top right of the Devices view you should see a green bug along with a number of other small buttons. Click the green bug.
10. You should now be attached/debugging your app.

Copy the diff file to the root of your repository, and then do:

git apply yourcoworkers.diff

More information about the apply command is available on its man page.

By the way: A better way to exchange whole commits by file is the combination of the commands git format-patch on the sender and then git am on the receiver, because it also transfers the authorship info and the commit message.

If the patch application fails and if the commits the diff was generated from are actually in your repo, you can use the -3 option of apply that tries to merge in the changes.

It also works with Unix pipe as follows:

git diff d892531 815a3b5 | git apply

I have the following extension methods:

    public static bool IsIn<T>(this T keyObject, params T[] collection)
    {
        return collection.Contains(keyObject);
    }

    public static bool IsIn<T>(this T keyObject, IEnumerable<T> collection)
    {
        return collection.Contains(keyObject);
    }

    public static bool IsNotIn<T>(this T keyObject, params T[] collection)
    {
        return keyObject.IsIn(collection) == false;
    }

    public static bool IsNotIn<T>(this T keyObject, IEnumerable<T> collection)
    {
        return keyObject.IsIn(collection) == false;
    }

Usage:

var inclusionList = new List<string> { "inclusion1", "inclusion2" };
var query = myEntities.MyEntity
                     .Select(e => e.Name)
                     .Where(e => e.IsIn(inclusionList));

var exceptionList = new List<string> { "exception1", "exception2" };
var query = myEntities.MyEntity
                     .Select(e => e.Name)
                     .Where(e => e.IsNotIn(exceptionList));

Very useful as well when passing values directly:

var query = myEntities.MyEntity
                     .Select(e => e.Name)
                     .Where(e => e.IsIn("inclusion1", "inclusion2"));

var query = myEntities.MyEntity
                     .Select(e => e.Name)
                     .Where(e => e.IsNotIn("exception1", "exception2"));

Try this and tell my if it works hope it help you:

string value = Convert.ToString(Console.ReadLine());

Switch(value)
{
    Case "abc":

    break;

    default:

    break;
}       

In your example, the first function does actually complete before the second function is started. setTimeout does not hold execution of the function until the timeout is reached, it will simply start a timer in the background and execute your alert statement after the specified time.

There is no native way of doing a "sleep" in JavaScript. You could write a loop that checks for the time, but that will put a lot of strain on the client. You could also do the Synchronous AJAX call, as emacsian described, but that will put extra load on your server. Your best bet is really to avoid this, which should be simple enough for most cases once you understand how setTimeout works.

You can simply cast to bool, dont forget to handle zero.

function isEmpty(string $string): bool {
    if($string === '0') {
        return false;
    }
    return !(bool)$string;
}

var_dump(isEmpty('')); // bool(true)
var_dump(isEmpty('foo')); // bool(false)
var_dump(isEmpty('0')); // bool(false)

var exists = $("#yourSelect option")
               .filter(function (i, o) { return o.value === yourValue; })
               .length > 0;

This has the advantage of automatically escaping the value for you, which makes random quotes in the text much easier to deal with.

The best solution we found was to team up with one of those intermediaries. Otherwise you will have to deal with a bunch of other requirements like PCI compliance. We use Verifone's IPCharge and it works quite well.

If you are looking to just repopulate the fields with the values that were posted in them, then just echo the post value back into the field, like so:

<input type="text" name="myField1" value="<?php echo isset($_POST['myField1']) ? $_POST['myField1'] : '' ?>" />

You are looking to use dirname. If you only want that one directory, you can use os.path.basename,

When put all together it looks like this:

os.path.basename(os.path.dirname('dir/sub_dir/other_sub_dir/file_name.txt'))

That should get you "other_sub_dir"

The following is not the ideal approach, but I originally proposed,using os.path.split, and simply get the last item. which would look like this:

os.path.split(os.path.dirname('dir/sub_dir/other_sub_dir/file_name.txt'))[-1]

Here's a great tip that nobody mentioned. In the controller that the function is within, you need to include the location provider:

app.controller('SlideController', ['$scope', '$location',function($scope, $location){ 
$scope.goNext = function (hash) { 
$location.path(hash);
 }

;]);

 <!--the code to call it from within the partial:---> <div ng-click='goNext("/page2")'>next page</div>

You can also do it without the [xml] cast. (Although xpath is a world unto itself. https://www.w3schools.com/xml/xml_xpath.asp)

$xml = (select-xml -xpath / -path stack.xml).node
$xml.objects.object.property

Or just this, xpath is case sensitive. Both have the same output:

$xml = (select-xml -xpath /Objects/Object/Property -path stack.xml).node
$xml


Name         Type                                                #text
----         ----                                                -----

DisplayName  System.String                                       SQL Server Agent (MSSQLSERVER)

At a minimum, change this:

function BlockID() {
    var IDs = new Array();
        images['s'] = "Images/Block_01.png";
        images['g'] = "Images/Block_02.png";
        images['C'] = "Images/Block_03.png";
        images['d'] = "Images/Block_04.png";
    return IDs;
}

To this:

function BlockID() {
    var IDs = new Object();
        IDs['s'] = "Images/Block_01.png";
        IDs['g'] = "Images/Block_02.png";
        IDs['C'] = "Images/Block_03.png";
        IDs['d'] = "Images/Block_04.png";
    return IDs;
}

There are a couple fixes to point out. First, images is not defined in your original function, so assigning property values to it will throw an error. We correct that by changing images to IDs. Second, you want to return an Object, not an Array. An object can be assigned property values akin to an associative array or hash -- an array cannot. So we change the declaration of var IDs = new Array(); to var IDs = new Object();.

After those changes your code will run fine, but it can be simplified further. You can use shorthand notation (i.e., object literal property value shorthand) to create the object and return it immediately:

function BlockID() {
    return {
            "s":"Images/Block_01.png"
            ,"g":"Images/Block_02.png"
            ,"C":"Images/Block_03.png"
            ,"d":"Images/Block_04.png"
    };
}

Put 0 as default in SQL or add 0 into your area of table

I was getting same error (TypeError: unhashable type: 'slice') with below code:

included_cols = [2,4,10]

Resolved with below code by putting iloc after dataset:

included_cols = [2,4,10]
dataset = dataset.iloc[:,included_cols]  #Columns 2,4 and 10 are included.

Move all of your state and your handleClick function from Header to your MainWrapper component.

Then pass values as props to all components that need to share this functionality.

class MainWrapper extends React.Component {
    constructor() {
        super();
        this.state = {
            sidbarPushCollapsed: false,
            profileCollapsed: false
        };
        this.handleClick = this.handleClick.bind(this);
    }
    handleClick() {
        this.setState({
            sidbarPushCollapsed: !this.state.sidbarPushCollapsed,
            profileCollapsed: !this.state.profileCollapsed

        });
    }
    render() {
        return (
           //...
           <Header 
               handleClick={this.handleClick} 
               sidbarPushCollapsed={this.state.sidbarPushCollapsed}
               profileCollapsed={this.state.profileCollapsed} />
        );

Then in your Header's render() method, you'd use this.props:

<button type="button" id="sidbarPush" onClick={this.props.handleClick} profile={this.props.profileCollapsed}>

def function(a):
    if a == '1':
        print ('1a')
    elif a == '2':
        print ('2a')
    else:
        print ('3a')

Some great help found here. However, I still could not make it to work despite loading JAR properly. I found out later that I accidentally created module in the file structure instead of regular folder and this very module was pre-selected in the project setting.

Here is the footprint:

File -> Project Structure -> Modules -> (select proper module if you have more) -> Dependencies -> + -> JAR or Libraries

Try this one in your controller, in the same order:

$scope.typeOptions = [
    { name: 'Feature', value: 'feature' }, 
    { name: 'Bug', value: 'bug' }, 
    { name: 'Enhancement', value: 'enhancement' }
];
$scope.form.type = $scope.typeOptions[0];

From the SQL Server Management Studio you can right click on your database and select:

Then simply proceed through the wizard. Make sure to set 'Script Data' to TRUE when prompted to choose the script options.

You are opening the csv file in binary mode, it should be 'w'

import csv

# open csv file in write mode with utf-8 encoding
with open('output.csv','w',encoding='utf-8',newline='')as w:
    fieldnames = ["SNo", "States", "Dist", "Population"]
    writer = csv.DictWriter(w, fieldnames=fieldnames)
    # write list of dicts
    writer.writerows(list_of_dicts) #writerow(dict) if write one row at time

Header files can contain any valid C code, since they are injected into the compilation unit by the pre-processor prior to compilation.

If a header file contains a function, and is included by multiple .c files, each .c file will get a copy of that function and create a symbol for it. The linker will complain about the duplicate symbols.

It is technically possible to create static functions in a header file for inclusion in multiple .c files. Though this is generally not done because it breaks from the convention that code is found in .c files and declarations are found in .h files.

See the discussions in C/C++: Static function in header file, what does it mean? for more explanation.

and rebuild. it works just for fine for me

I'd re-iterate Donny V. answer and Josh's

"The only reason I wouldn't use the async version is if I were trying to support an older version of .NET that does not already have built in async support."

(and upvote if I had the reputation.)

I can't remember the last time if ever, I was grateful of the fact HttpWebRequest threw exceptions for status codes >= 400. To get around these issues you need to catch the exceptions immediately, and map them to some non-exception response mechanisms in your code...boring, tedious and error prone in itself. Whether it be communicating with a database, or implementing a bespoke web proxy, its 'nearly' always desirable that the Http driver just tell your application code what was returned, and leave it up to you to decide how to behave.

Hence HttpClient is preferable.

Encapsulation is a strategy used as part of abstraction. Encapsulation refers to the state of objects - objects encapsulate their state and hide it from the outside; outside users of the class interact with it through its methods, but cannot access the classes state directly. So the class abstracts away the implementation details related to its state.

Abstraction is a more generic term, it can also be achieved by (amongst others) subclassing. For example, the interface List in the standard library is an abstraction for a sequence of items, indexed by their position, concrete examples of a List are an ArrayList or a LinkedList. Code that interacts with a List abstracts over the detail of which kind of a list it is using.

Abstraction is often not possible without hiding underlying state by encapsulation - if a class exposes its internal state, it can't change its inner workings, and thus cannot be abstracted.

You have to define the text color in the layout *simple_list_item_1* that defines the layout of each of your items.

You set the background color of the LinearLayout and not of the ListView. The background color of the child items of the LinearLayout are transparent by default (in most cases).

And you set the black text color for the TextView that is not part of your ListView. It is an own item (child item of the LinearLayout) here.

Use PaulGuo's jSQL, a SQL like database using javascript. For example:

var db = new jSQL();
db.create('dbname', testListData).use('dbname');
var data = db.select('*').where(function(o) {
    return o.name == 'Jacking';
}).listAll();

Try this:

preg_replace('/[^0-9]/', '', '604-619-5135');

preg_replace uses PCREs which generally start and end with a /.

Replace

volume = (4 / 3) Math.PI * Math.pow(radius, 3);

With:

volume = (4 * Math.PI * Math.pow(radius, 3)) / 3;

RoboCopy did not work for me, and there are some good solutions here, but none explained the XCopy switches and what they do. Also you need quotes in case your path has spaces in it.

xcopy /i /e "C:\temp\folder 1" "C:\temp\folder 2"

Here is the documentation from Microsoft:

XCopy MS Documentation

/s: Specifies to include subdirectories. Excludes empty subdirectories
/e: Copies all subdirectories, even if they are empty
/i: specifies the destination is a folder (Otherwise it prompts you)

I preface my reply by admitting I have no experience with Docker, other than as an avid observer of what looks to be a really neat solution that's gaining a lot of traction.

I do have a decent amount of experience with Vagrant and can highly recommend it. It's certainly a more heavyweight solution in terms of it being VM based instead of LXC based. However, I've found a decent laptop (8 GB RAM, i5/i7 CPU) has no trouble running a VM using Vagrant/VirtualBox alongside development tooling.

One of the really great things with Vagrant is the integration with Puppet/Chef/shell scripts for automating configuration. If you're using one of these options to configure your production environment, you can create a development environment which is as close to identical as you're going to get, and this is exactly what you want.

The other great thing with Vagrant is that you can version your Vagrantfile along with your application code. This means that everyone else on your team can share this file and you're guaranteed that everyone is working with the same environment configuration.

Interestingly, Vagrant and Docker may actually be complimentary. Vagrant can be extended to support different virtualization providers, and it may be possible that Docker is one such provider which gets support in the near future. See https://github.com/dotcloud/docker/issues/404 for recent discussion on the topic.

You could use OrderedDict (requires Python 2.7) or higher.

Also, note that OrderedDict({'a': 1, 'b':2, 'c':3}) won't work since the dict you create with {...} has already forgotten the order of the elements. Instead, you want to use OrderedDict([('a', 1), ('b', 2), ('c', 3)]).

As mentioned in the documentation, for versions lower than Python 2.7, you can use this recipe.

get_curr_date () {
    # get unix time
    DATE=$(date +%s)
    echo "DATE_CURR : "$DATE
}

conv_utime_hread () {
    # convert unix time to human readable format
    DATE_HREAD=$(date -d @$DATE +%Y%m%d_%H%M%S)
    echo "DATE_HREAD          : "$DATE_HREAD
}

Just in case... sometimes happens that you are calling umount from the terminal, and your current directory belongs to the mounted filesystem.

Looping didn't seem to work for me and I wanted to ignore origin/master. Here's what worked for me.

git branch -r | grep -v HEAD | awk -F'/' '{print $2 " " $1"/"$2}' | xargs -L 1 git branch -f --track

After that:

git fetch --all
git pull --all

It is possible to roll your own version of PHP's die:

function die(msg)
{
    throw msg;
}

function test(arg1)
{
    arg1 = arg1 || die("arg1 is missing"); 
}

test();

While it was primarly designed for the browser, it works well with Jaxer and Rhino.

I don't know node.js yet but if you can cache some JS and functions in memory, the speed should be even more impressive.

I got the same error when using policy as below, although i have "s3:ListBucket" for s3:ListObjects operation.

{
"Version": "2012-10-17",
"Statement": [
    {
        "Action": [
            "s3:ListBucket",
            "s3:GetObject",
            "s3:GetObjectAcl"
        ],
        "Resource": [
            "arn:aws:s3:::<bucketname>/*",
            "arn:aws:s3:::*-bucket/*"
        ],
        "Effect": "Allow"
    }
  ]
 }

Then i fixed it by adding one line "arn:aws:s3:::bucketname"

"Version": "2012-10-17",
"Statement": [
    {
        "Action": [
            "s3:ListBucket",

        ],
        "Resource": [
             "arn:aws:s3:::<bucketname>",
            "arn:aws:s3:::<bucketname>/*",
            "arn:aws:s3:::*-bucket/*"
        ],

This is one of the best suggestion in which is done using query. Good for those who has a lot of databases just like me. Can run it using a script.

https://medium.com/@bharatdwarkani/shrinking-sql-server-db-log-file-size-sql-server-db-maintenance-7ddb0c331668

USE DatabaseName;
GO
-- Truncate the log by changing the database recovery model to SIMPLE.
ALTER DATABASE DatabaseName

GO
-- Reset the database recovery model.
ALTER DATABASE DatabaseName

Creating a separate directive for this is not needed. There is already a build in Angular UI password validation tool. With this you could do:

<input name="password" required ng-model="password">
<input name="confirm_password"
       ui-validate=" '$value==password' "
       ui-validate-watch=" 'password' ">

 Passwords match? {{!!form.confirm_password.$error.validator}}

I prefer this because it prevents a single item list with an empty item if your source string is empty:

  IEnumerable<string> namesList = 
      !string.isNullOrEmpty(names) ? names.Split(',') : Enumerable.Empty<string>();

Rather than write your own code you can use an IntBuffer to wrap the existing int[] without having to copy the data into an Integer array

int[] a = {1,2,3,4};
IntBuffer b = IntBuffer.wrap(a);

IntBuffer implements comparable so you are able to use the code you already have written. Formally maps compare keys such that a.equals(b) is used to say two keys are equal, so two IntBuffers with array 1,2,3 - even if the arrays are in different memory locations - are said to be equal and so will work for your frequency code.

ArrayList<int[]> data = ... // load a dataset`

Map<IntBuffer, Double> frequencies = new HashMap<IntBuffer, Double>();

for(int[] a : data) {

    IntBuffer q = IntBuffer.wrap(a);

    if(frequencies.containsKey(q)) {
        frequencies.put(q, tfs.get(q) + p);
    } else {
        frequencies.put(q, p);
    }

}

Hope that helps

Actually you can use a switch statement with Strings in Java...unfortunately this is a new feature of Java 7, and most people are not using Java 7 yet because it's so new.

Contrary to std::vector and std::array, std::unique_ptr can own a NULL pointer.
This comes in handy when working with C APIs that expect either an array or NULL:

void legacy_func(const int *array_or_null);

void some_func() {    
    std::unique_ptr<int[]> ptr;
    if (some_condition) {
        ptr.reset(new int[10]);
    }

    legacy_func(ptr.get());
}

Add an ORDER BY ONE.ID ASC at the end of your first query.

By default there is no ordering.

To avoid closing the parentheses for each line you can simply use double quotes with a backslash to escape the newline:

"select attr1, attr2, attr3, attr4, attr5, attr6, attr7 \
from table1, table2, table3, etc, etc, etc, etc, etc, \
where etc etc etc etc etc etc etc etc etc etc etc etc etc"

As some of the answers point out, createdb is a command line utility that could be used to create database.

Assuming you have a user named dbuser, the following command could be used to create a database and provide access to dbuser:

createdb -h localhost -p 5432 -U dbuser testdb

Replace localhost with your correct DB host name, 5432 with correct DB port, and testdb with the database name you want to create.

Now psql could be used to connect to this newly created database:

psql -h localhost -p 5432 -U dbuser -d testdb

Tested with createdb and psql versions 9.4.15.

A simple algorithm that gives you random numbers without duplicates can be found in the book Programming Pearls p. 127.

Attention: The resulting array contains the numbers in order! If you want them in random order, you have to shuffle the array, either with Fisher–Yates shuffle or by using a List and call Collections.shuffle().

The benefit of this algorithm is that you do not need to create an array with all the possible numbers and the runtime complexity is still linear O(n).

public static int[] sampleRandomNumbersWithoutRepetition(int start, int end, int count) {
    Random rng = new Random();

    int[] result = new int[count];
    int cur = 0;
    int remaining = end - start;
    for (int i = start; i < end && count > 0; i++) {
        double probability = rng.nextDouble();
        if (probability < ((double) count) / (double) remaining) {
            count--;
            result[cur++] = i;
        }
        remaining--;
    }
    return result;
}

I just thought to give you the reason why your solution did not work:

When $(document).ready() is executed only the $('#topbar-show') selector can find a matching element from the DOM. The #topbar-show element has not been created yet.

To get past this problem, you may use live event bindings

$('#topbar-show').live('click',function(e){});
$('#topbar-hide').live('click',function(e){});

This is the most simple way to fix you solution. The rest of these answer go further to provide you a better solutions instead that do not modify the hopefully permanent id attribute.

Well the answer from @sahhhm didn't work for me, what i needed was to trigger the backKey from a custom button so what I did was I simply called,

backAction.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                MyRides.super.onBackPressed();

When overriding

There are three unique situations:

• 4 numbers, e.g. Margin="a,b,c,d".
• 2 numbers, e.g. Margin="a,b".
• 1 number, e.g. Margin="a".

4 Numbers

If there are 4 numbers, then its left, top, right, bottom (a clockwise circle starting from the middle left margin). First number is always the "West" like "WPF":

<object Margin="left,top,right,bottom"/>

Example: if we use Margin="10,20,30,40" it generates:

2 Numbers

If there are 2 numbers, then the first is left & right margin thickness, the second is top & bottom margin thickness. First number is always the "West" like "WPF":

<object Margin="a,b"/> // Equivalent to Margin="a,b,a,b".

Example: if we use Margin="10,30", the left & right margin are both 10, and the top & bottom are both 30.

1 Number

If there is 1 number, then the number is repeated (its essentially a border thickness).

<object Margin="a"/> // Equivalent to Margin="a,a,a,a".

Example: if we use Margin="20" it generates:

Update 2020-05-27

Have been working on a large-scale WPF application for the past 5 years with over 100 screens. Part of a team of 5 WPF/C#/Java devs. We eventually settled on either using 1 number (for border thickness) or 4 numbers. We never use 2. It is consistent, and seems to be a good way to reduce cognitive load when developing.

The rule:

All width numbers start on the left (the "West" like "WPF") and go clockwise (if two numbers, only go clockwise twice, then mirror the rest).

Bootstrap has a way of using media queries to define the different task for different sites. It uses four breakpoints.

we have extra small screen sizes which are less than 576 pixels that small in which I mean it's size from 576 to 768 pixels.

medium screen sizes take up screen size from 768 pixels up to 992 pixels large screen size from 992 pixels up to 1200 pixels.

E.g Small Text

This means that at the small screen between 576px and 768px, center the text For medium screen, change "sm" to "md" and same goes to large "lg"

You can use df.dropDuplicates(['col1','col2']) to get only distinct rows based on colX in the array.

check this quick reminder of file path

Here is all you need to know about relative file paths:

• Starting with "/" returns to the root directory and starts there
• Starting with "../" moves one directory backwards and starts there
• Starting with "../../" moves two directories backwards and starts there (and so on...)
• To move forward, just start with the first subdirectory and keep moving forward

This simple filtering can be achieved in many ways with Python. The best approach is to use "list comprehensions" as follows:

>>> lst = ['a', 'ab', 'abc', 'bac']
>>> [k for k in lst if 'ab' in k]
['ab', 'abc']

Another way is to use the filter function. In Python 2:

>>> filter(lambda k: 'ab' in k, lst)
['ab', 'abc']

In Python 3, it returns an iterator instead of a list, but you can cast it:

>>> list(filter(lambda k: 'ab' in k, lst))
['ab', 'abc']

Though it's better practice to use a comprehension.

You can insert into a table from a SELECT.

INSERT INTO
  Employee (emp_id, emp_name, emp_address, emp_state, emp_position, emp_manager)
SELECT
  001,
  'John Doe',
  '1 River Walk, Green Street',
  (SELECT id FROM state WHERE name = 'New York'),
  (SELECT id FROM positions WHERE name = 'Sales Executive'),
  (SELECT id FROM manager WHERE name = 'Barry Green')
FROM
  dual

Or, similarly...

INSERT INTO
  Employee (emp_id, emp_name, emp_address, emp_state, emp_position, emp_manager)
SELECT
  001,
  'John Doe',
  '1 River Walk, Green Street',
  state.id,
  positions.id,
  manager.id
FROM
  state
CROSS JOIN
  positions
CROSS JOIN
  manager
WHERE
      state.name     = 'New York'
  AND positions.name = 'Sales Executive'
  AND manager.name   = 'Barry Green'

Though this one does assume that all the look-ups exist. If, for example, there is no position name 'Sales Executive', nothing would get inserted with this version.

Here's my best try:

    .inner_shadow {_x000D_
    color:transparent;_x000D_
    background-color:white;_x000D_
    text-shadow: 0 0 20px rgba(198,28,39,0.8), 0 0 0 black;_x000D_
    font-family:'ProclamateHeavy';  // Or whatever floats your boat_x000D_
    font-size:150px;_x000D_
    }

   _x000D_
    <span class="inner_shadow">Inner Shadow</span>_x000D_
   

The problem is how to clip the shadow that bleeds around the edges!!! I tried in webkit using background-clip:text, but webkit renders the shadow above the background so it doesn't work.

Making a Text Mask with CSS?

Without a top mask layer it is impossible to do a true inner shadow on text.

Perhaps someone should recommend that the W3C add background-clip: reverse-text, that would cut a mask through the background instead of cutting the background to fit inside the text.

Either that or render the text-shadow as part of the background and clip it with background-clip: text.

I tried absolutely positioning an identical text element above it, but the problem is background-clip: text crops the background to fit inside the text, but we need the reverse of that.

I tried using text-stroke: 20px white; on both this element and the one above it, but the text stroke goes in as well as out.

Alternate Methods

Since there is currently no way to make an inverted-text mask in CSS, you could turn to SVG or Canvas and make a text replacement image with the three layers to get your effect.

Since SVG is a subset of XML, SVG text would still be select-able and searchable, and the effect can be produced with less code than Canvas.

It would be harder to achieve this with Canvas because it doesn't have a dom with layers like SVG does.

You could produce the SVG either server-side, or as a javascript text-replacement method in the browser.

The question may be getting old, but I've struggled with the same issue just now.

After deleting passwords with resetroot.bat, as instructed by Nedshed, you can choose another password by going to http://localhost/security/index.php

//for update

(from x in dataBase.Customers
         where x.Name == "Test"
         select x).ToList().ForEach(xx => xx.Name="New Name");

//for delete

dataBase.Customers.RemoveAll(x=>x.Name=="Name");

The easiest way to do so is using jQuery and animate.css animation library.

Javascript

/* --- Show DIV --- */
$( '.example' ).removeClass( 'fadeOutRight' ).show().addClass( 'fadeInRight' );

/* --- Hide DIV --- */
$( '.example' ).removeClass( 'fadeInRight' ).addClass( 'fadeOutRight' );

HTML

<div class="example">Some text over here.</div>

Easy enough to implement. Just don't forget to include the animate.css file in the header :)

Make SymbolIndexer( const SymbolIndexer& ) private. If you're assigning to a reference, you're not copying.

SO...older thread, I know, but...

EDIT

@RoccoMusolino had a nice catch; here's an alternative:

TL;DR:

 const intArray = [...("5 6 7 69 foo 0".split(' ').filter(i => /\d/g.test(i)))]

WRONG: "5 6 note this foo".split(" ").map(Number).filter(Boolean); // [5, 6]

There is a subtle flaw in the more elegant solutions listed here, specifically @amillara and @Marcus' otherwise beautiful answers.

The problem occurs when an element of the string array isn't integer-like, perhaps in a case without validation on an input. For a contrived example...

The problem:

var effedIntArray = "5 6 7 69 foo".split(' ').map(Number); // [5, 6, 7, 69, NaN]

Since you obviously want a PURE int array, that's a problem. Honestly, I didn't catch this until I copy-pasted SO code into my script... :/

The (slightly-less-baller) fix:

var intArray = "5 6 7 69 foo".split(" ").map(Number).filter(Boolean); // [5, 6, 7, 69]

So, now even when you have crap int string, your output is a pure integer array. The others are really sexy in most cases, but I did want to offer my mostly rambly w'actually. It is still a one-liner though, to my credit...

Hope it saves someone time!

This will search and replace all non ASCII letters:

String resultString = subjectString.replaceAll("[^\\x00-\\x7F]", "");

Just an improvement to the nice answer given by @vuhung3990. I implemented the solution and works great but if I touch one radio button it will be selected and nothing happens.

I suggest to also change page when a radio button is tapped. To do this, simply add a listener to the radioGroup:

mPager = (ViewPager) findViewById(R.id.pager);
final RadioGroup radioGroup = (RadioGroup)findViewById(R.id.radiogroup);    
radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(RadioGroup group, int checkedId) {
                switch (checkedId) {
                    case R.id.radioButton :
                        mPager.setCurrentItem(0, true);
                        break;
                    case R.id.radioButton2 :
                        mPager.setCurrentItem(1, true);
                        break;
                    case R.id.radioButton3 :
                        mPager.setCurrentItem(2, true);
                        break;
                }
            }
        });

Ruby has a few methods for changing the case of strings. To convert to lowercase, use downcase:

"hello James!".downcase    #=> "hello james!"

Similarly, upcase capitalizes every letter and capitalize capitalizes the first letter of the string but lowercases the rest:

"hello James!".upcase      #=> "HELLO JAMES!"
"hello James!".capitalize  #=> "Hello james!"
"hello James!".titleize    #=> "Hello James!"

If you want to modify a string in place, you can add an exclamation point to any of those methods:

string = "hello James!"
string.downcase!
string   #=> "hello james!"

Refer to the documentation for String for more information.

Which objects are you using? Just tried that with a sample class and it worked fine:

class MyClass:
  i = 123456
  def f(self):
    return "hello world"

b = MyClass()
b.c = MyClass()
setattr(b.c, 'test', 123)
b.c.test

And I got 123 as the answer.

The only situation where I see this failing is if you're trying a setattr on a builtin object.

Update: From the comment this is a repetition of: Why can't you add attributes to object in python?

My own solution was created a method like the next one:

-(void)setColorForText:(NSString*) textToFind originalText:(NSString *)originalString withColor:(UIColor*)color andLabel:(UILabel *)label{

NSMutableAttributedString *attString = [[NSMutableAttributedString alloc] initWithString:originalString];
NSRange range = [originalString rangeOfString:textToFind];

[attString addAttribute:NSForegroundColorAttributeName value:color range:range];

label.attributedText = attString;

if (range.location != NSNotFound) {
    [attString addAttribute:NSForegroundColorAttributeName value:color range:range];
}
label.attributedText = attString; }

It worked with just one different color in the same text but you can adapt it easily to more colores in the same sentence.

set this :

#inner-right {
    height: 100%;
    max-height: 96%;//change here
    overflow: auto;
    background: ivory;
}

this will solve your problem.

You're looking for the .filter() function:

  $scope.appIds = $scope.applicationsHere.filter(function(obj) {
    return obj.selected;
  });

That'll produce an array that contains only those objects whose "selected" property is true (or truthy).

edit sorry I was getting some coffee and I missed the comments - yes, as jAndy noted in a comment, to filter and then pluck out just the "id" values, it'd be:

  $scope.appIds = $scope.applicationsHere.filter(function(obj) {
    return obj.selected;
  }).map(function(obj) { return obj.id; });

Some functional libraries (like Functional, which in my opinion doesn't get enough love) have a .pluck() function to extract property values from a list of objects, but native JavaScript has a pretty lean set of such tools.

A Window is always shown independently, A Page is intended to be shown inside a Frame or inside a NavigationWindow.

In order to check if an object is compatible with a given type variable, instead of writing

u is t

you should write

typeof(t).IsInstanceOfType(u)

The best explanation I have found is by Mike Acton, Understanding Strict Aliasing. It's focused a little on PS3 development, but that's basically just GCC.

From the article:

"Strict aliasing is an assumption, made by the C (or C++) compiler, that dereferencing pointers to objects of different types will never refer to the same memory location (i.e. alias each other.)"

So basically if you have an int* pointing to some memory containing an int and then you point a float* to that memory and use it as a float you break the rule. If your code does not respect this, then the compiler's optimizer will most likely break your code.

The exception to the rule is a char*, which is allowed to point to any type.

For a good quality x264 encoding of 1060i, done by a computer, not a mobile device, not in real time, you could use a bitrate at about 5 MBps. That means 2250 MB/hour of encoded material. Recommend you deinterlace the footage and compress as progressive.

This isn't my answer, but it definitely resonates with me. It's from ThoughtWorks' Technology Radar from October 2012:

Two things have caused fatigue with XML-based build tools like Ant and Maven: too many angry pointy braces and the coarseness of plug-in architectures. While syntax issues can be dealt with through generation, plug-in architectures severely limit the ability for build tools to grow gracefully as projects become more complex. We have come to feel that plug-ins are the wrong level of abstraction, and prefer language-based tools like Gradle and Rake instead, because they offer finer-grained abstractions and more flexibility long term.

The simplest way I was able to achieve a similar feat to use the code below (reference), but I would suggest not to make API calls in controllers(SOLID principles). Also autowiring this way is better optimsed than the traditional way of doing it.

You are asking to initialize four variables using a single float object, which of course is not iterable. You can do -

1. grade_1, grade_2, grade_3, grade_4 = [0.0 for _ in range(4)]
2. grade_1 = grade_2 = grade_3 = grade_4 = 0.0

Unless you want to initialize them with different values of course.

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {      
       app.UseCors(builder => builder
                .AllowAnyHeader()
                .AllowAnyMethod()
                .SetIsOriginAllowed((host) => true)
                .AllowCredentials()
            );
    }

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddCors();
    }

Starting from Java 1.7 you can use try-with-resources like this:

  private Integer findRandomOpenPortOnAllLocalInterfaces() throws IOException {
    try (
        ServerSocket socket = new ServerSocket(0);
    ) {
      return socket.getLocalPort();

    }
  }

If you need to find an open port on a specific interface check ServerSocket documentation for alternative constructors.

Warning: Any code using the port number returned by this method is subject to a race condition - a different process / thread may bind to the same port immediately after we close the ServerSocket instance.

If you want to do an ajax call or a simple javascript function, don't forget to close your function with the return false

like this:

function DoAction(id, name) 
{ 
    // your code
    return false;
}

If use are already have Apache commons-io available on the classpath, you may use:

Process p = new ProcessBuilder("cat", "/etc/something").start();
String stderr = IOUtils.toString(p.getErrorStream(), Charset.defaultCharset());
String stdout = IOUtils.toString(p.getInputStream(), Charset.defaultCharset());

In my case I was checking work done on my office computer (with Visio installed) at home (no Visio). Even though VBA appeared to be getting hung up on simple default functions, the problem was that I had references to the Visio libraries still active.

this my query for search records based on searchdata and between start to end date

Can try like this

var code = "<script></" + "script>";
$("#someElement").append(code);

The only reason you can't do "<script></script>" is because the string isn't allowed inside javascript because the DOM layer can't parse what's js and what's HTML.

The documentation in the w3 link

http://www.w3.org/TR/REC-xml/#sec-starttags

says that this are the recomended forms.

<test></test>
<test/>

The attribute mentioned in the other answer is validation mechanism and not a representation of state. Please refer to the http://www.w3.org/TR/xmlschema-1/#xsi_nil

XML Schema: Structures introduces a mechanism for signaling that an element should be accepted as ·valid· when it has no content despite a content type which does not require or even necessarily allow empty content. An element may be ·valid· without content if it has the attribute xsi:nil with the value true. An element so labeled must be empty, but can carry attributes if permitted by the corresponding complex type.

To clarify this answer: Content

  <Book>
    <!--Invalid construct since the element attribute xsi:nil="true" signal that the element must be empty-->
    <BuildAttributes HardCover="true" Glued="true" xsi:nil="true">
      <anotherAttribute name="Color">Blue</anotherAttribute>
    </BuildAttributes>
    <Index></Index>
    <pages>
      <page pageNumber="1">Content</page>            
    </pages>
    <!--Missing ISBN number could be confusing and misguiding since its not present-->
  </Book>
</Books>

In you app config file change the url to localhost/example/public

Then when you want to link to something

<a href="{{ url('page') }}">Some Text</a>

without blade

<a href="<?php echo url('page') ?>">Some Text</a>

To add on this, today you are able to use pandas to import json:
https://pandas.pydata.org/pandas-docs/stable/generated/pandas.read_json.html You may want to do a careful use of the orient parameter.

All these results in null:

document.getElementById('volume');
document.getElementById('bytesLoaded');
document.getElementById('startBytes');
document.getElementById('bytesTotal');

You need to do a null check in updateHTML like this:

function updateHTML(elmId, value) {
  var elem = document.getElementById(elmId);
  if(typeof elem !== 'undefined' && elem !== null) {
    elem.innerHTML = value;
  }
}

For pushing a single tag: git push <reponame> <tagname>

For instance, git push production 1.0.0. Tags are not bound to branches, they are bound to commits.

When you want to have the tag's content in the master branch, do that locally on your machine. I would assume that you continued developing in your local master branch. Then just a git push origin master should suffice.

You have Two alternatives :

First one is to create a ServletImageLoader that would take as a parameter an identifier of your image (the path of the image or a hash) that you will use inside the Servlet to handle your image, and it will print to the response stream the loaded image from the server.

Second one is to create a folder inside your application's ROOT folder and just save the relative path to your images.

selection=selection.values

this do things at a very fast way.

A function can be in-lined into a SQL statement, e.g.

select foo
      ,fn_bar (foo)
  from foobar

Which cannot be done with a stored procedure. The architecture of the query optimiser limits what can be done with functions in this context, requiring that they are pure (i.e. the same inputs always produce the same output). This restricts what can be done in the function, but allows it to be used in-line in the query if it is defined to be "pure".

Otherwise, a function (not necessarily deterministic) can return a variable or a result set. In the case of a function returning a result set, you can join it against some other selection in a query. However, you cannot use a non-deterministic function like this in a correlated subquery as the optimiser cannot predict what sort of result set will be returned (this is computationally intractable, like the halting problem).

1) in a query window in SQL Server Management Studio, run the command:

SET SHOWPLAN_ALL ON

2) run your slow query

3) your query will not run, but the execution plan will be returned. store this output

4) run your fast version of the query

5) your query will not run, but the execution plan will be returned. store this output

6) compare the slow query version output to the fast query version output.

7) if you still don't know why one is slower, post both outputs in your question (edit it) and someone here can help from there.

The syntax problem is shadowing method and variable names. In the current version sort_word_list() is a method, and sorted_word_list is a variable, whereas num_words is both. Also, list.sort() modifies the list and replaces it with a sorted version; the sorted(list) function actually returns a new list.

But I suspect this indicates a design problem. What's the point of calls like

test.parser()
test.sort_word_list()
test.num_words()

which don't do anything? You should probably just have the methods figure out whether the appropriate counting and/or sorting has been done, and, if appropriate, do the count or sort and otherwise just return something.

E.G.,

def sort_word_list(self):
   if self.sorted_word_list is not None:
      self.sorted_word_list = sorted(self.word_list)
   return self.sorted_word_list

(Alternately, you could use properties.)

Give you a pagination component, which is maybe a little difficult to understand for newbie to react:

https://www.npmjs.com/package/pagination

Yes, . (dot) would match any character. Use:

^.{1,35}$

There are very few cases where you want to use except:. Doing this captures any exception, which can be hard to debug, and it captures exceptions including SystemExit and KeyboardInterupt, which can make your program annoying to use..

At the very simplest, you would catch urllib2.URLError:

try:
    urllib2.urlopen("http://example.com", timeout = 1)
except urllib2.URLError, e:
    raise MyException("There was an error: %r" % e)

The following should capture the specific error raised when the connection times out:

import urllib2
import socket

class MyException(Exception):
    pass

try:
    urllib2.urlopen("http://example.com", timeout = 1)
except urllib2.URLError, e:
    # For Python 2.6
    if isinstance(e.reason, socket.timeout):
        raise MyException("There was an error: %r" % e)
    else:
        # reraise the original error
        raise
except socket.timeout, e:
    # For Python 2.7
    raise MyException("There was an error: %r" % e)
