you can use sudo apt-get install python3-distutils by root permission.

i believe it worked here

In Python 3.8 the dirs_exist_ok keyword argument was added to shutil.copytree():

dirs_exist_ok dictates whether to raise an exception in case dst or any missing parent directory already exists.

So, the following will work in recent versions of Python, even if the destination directory already exists:

shutil.copytree(src, dest, dirs_exist_ok=True)  # 3.8+ only!

One major benefit is that it's more flexible than distutils.dir_util.copy_tree() as it takes additional arguments on files to ignore, etc. There is also a draft PEP (PEP 632, associated discussion), which suggests that distutils may be deprecated and then removed in future versions of Python 3.

As far as I can tell, this is a bug in setuptools where it isn't removing the setuptools specific options before calling up to the base class in the standard library: https://bitbucket.org/pypa/setuptools/issue/29/avoid-userwarnings-emitted-when-calling

If you have an unconditional import setuptools in your setup.py (as you should if using the setuptools specific options), then the fact the script isn't failing with ImportError indicates that setuptools is properly installed.

You can silence the warning as follows:

python -W ignore::UserWarning:distutils.dist setup.py <any-other-args>

Only do this if you use the unconditional import that will fail completely if setuptools isn't installed :)

(I'm seeing this same behaviour in a checkout from the post-merger setuptools repo, which is why I'm confident it's a setuptools bug rather than a system config problem. I expect pre-merge distribute would have the same problem)

Probably the best way to do this is to use the setuptools package_data directive. This does mean using setuptools (or distribute) instead of distutils, but this is a very seamless "upgrade".

Here's a full (but untested) example:

from setuptools import setup, find_packages

setup(
    name='your_project_name',
    version='0.1',
    description='A description.',
    packages=find_packages(exclude=['ez_setup', 'tests', 'tests.*']),
    package_data={'': ['license.txt']},
    include_package_data=True,
    install_requires=[],
)

Note the specific lines that are critical here:

package_data={'': ['license.txt']},
include_package_data=True,

package_data is a dict of package names (empty = all packages) to a list of patterns (can include globs). For example, if you want to only specify files within your package, you can do that too:

package_data={'yourpackage': ['*.txt', 'path/to/resources/*.txt']}

The solution here is definitely not to rename your non-py files with a .py extension.

See Ian Bicking's presentation for more info.

UPDATE: Another [Better] Approach

Another approach that works well if you just want to control the contents of the source distribution (sdist) and have files outside of the package (e.g. top-level directory) is to add a MANIFEST.in file. See the Python documentation for the format of this file.

Since writing this response, I have found that using MANIFEST.in is typically a less frustrating approach to just make sure your source distribution (tar.gz) has the files you need.

For example, if you wanted to include the requirements.txt from top-level, recursively include the top-level "data" directory:

include requirements.txt
recursive-include data *

Nevertheless, in order for these files to be copied at install time to the package’s folder inside site-packages, you’ll need to supply include_package_data=True to the setup() function. See Adding Non-Code Files for more information.

I would first create a DataTable with the columns that you require, then populate it via Linq-to-XML.

You could use a Select query to create an object that represents each row, then use the standard approach for creating DataRows for each item ...

class Quest
{
    public string Answer1;
    public string Answer2;
    public string Answer3;
    public string Answer4;
}

public static void Main()
{
    var doc = XDocument.Load("filename.xml");

    var rows = doc.Descendants("QuestId").Select(el => new Quest
    {
        Answer1 = el.Element("Answer1").Value,
        Answer2 = el.Element("Answer2").Value,
        Answer3 = el.Element("Answer3").Value,
        Answer4 = el.Element("Answer4").Value,
    });

    // iterate over the rows and add to DataTable ...

}

$dbhandle = sqlsrv_connect($myServer, $myUser, $myPass)
  or die("Couldn't connect to SQL Server on $myServer"); 

Hope it help.

When you are using Lombok builder you will get the above error.

 @JsonDeserialize(builder = StationResponse.StationResponseBuilder.class)
 public class StationResponse{
   //define required properties 
 }

I managed to download the file generated by the rest API URL much easier with this kind of code which worked just fine on my local:

    import React, {Component} from "react";
    import {saveAs} from "file-saver";

    class MyForm extends Component {

    constructor(props) {
        super(props);
        this.handleSubmit = this.handleSubmit.bind(this);
    }

    handleSubmit(event) {
        event.preventDefault();
        const form = event.target;
        let queryParam = buildQueryParams(form.elements);

        let url = 'http://localhost:8080/...whatever?' + queryParam;

        fetch(url, {
            method: 'GET',
            headers: {
                // whatever
            },
        })
            .then(function (response) {
                    return response.blob();
                }
            )
            .then(function(blob) {
                saveAs(blob, "yourFilename.xlsx");
            })
            .catch(error => {
                //whatever
            })
    }

    render() {
        return (
            <form onSubmit={this.handleSubmit} id="whateverFormId">
                <table>
                    <tbody>
                    <tr>
                        <td>
                            <input type="text" key="myText" name="myText" id="myText"/>
                        </td>
                        <td><input key="startDate" name="from" id="startDate" type="date"/></td>

                    </tr>
                    <tr>
                        <td colSpan="3" align="right">
                            <button>Export</button>
                        </td>
                    </tr>

                    </tbody>
                </table>
            </form>
        );
    }
}

function buildQueryParams(formElements) {
    let queryParam = "";

    //do code here
    
    return queryParam;

export default MyForm;

You can loop through the cells of any column in a table by knowing just its name and not its position. If the table is in sheet1 of the workbook:

Dim rngCol as Range
Dim cl as Range
Set rngCol = Sheet1.Range("TableName[ColumnName]")
For Each cl in rngCol
    cl.Value = "PHEV"
Next cl

The code above will loop through the data values only, excluding the header row and the totals row. It is not necessary to specify the number of rows in the table.

Use this to find the location of any column in a table by its column name:

Dim colNum as Long
colNum = Range("TableName[Column name to search for]").Column

This returns the numeric position of a column in the table.

Spring security is a filter based framework, it plants a WALL(HttpFireWall) before your application in terms of proxy filters or spring managed beans. Your request has to pass through multiple filters to reach your API.

Sequence of execution in Spring Security

1. WebAsyncManagerIntegrationFilter Provides integration between the SecurityContext and Spring Web's WebAsyncManager.
   

2. SecurityContextPersistenceFilter This filter will only execute once per request, Populates the SecurityContextHolder with information obtained from the configured SecurityContextRepository prior to the request and stores it back in the repository once the request has completed and clearing the context holder.
   Request is checked for existing session. If new request, SecurityContext will be created else if request has session then existing security-context will be obtained from respository.

3. HeaderWriterFilter Filter implementation to add headers to the current response.

4. LogoutFilter If request url is /logout(for default configuration) or if request url mathces RequestMatcher configured in LogoutConfigurer then

   • clears security context.
   • invalidates the session
   • deletes all the cookies with cookie names configured in LogoutConfigurer
   • Redirects to default logout success url / or logout success url configured or invokes logoutSuccessHandler configured.

5. UsernamePasswordAuthenticationFilter

   • For any request url other than loginProcessingUrl this filter will not process further but filter chain just continues.
   • If requested URL is matches(must be HTTP POST) default /login or matches .loginProcessingUrl() configured in FormLoginConfigurer then UsernamePasswordAuthenticationFilter attempts authentication.
   • default login form parameters are username and password, can be overridden by usernameParameter(String), passwordParameter(String).
   • setting .loginPage() overrides defaults
   • While attempting authentication
     • an Authentication object(UsernamePasswordAuthenticationToken or any implementation of Authentication in case of your custom auth filter) is created.
     • and authenticationManager.authenticate(authToken) will be invoked
       
     • Note that we can configure any number of AuthenticationProvider authenticate method tries all auth providers and checks any of the auth provider supports authToken/authentication object, supporting auth provider will be used for authenticating. and returns Authentication object in case of successful authentication else throws AuthenticationException.
   • If authentication success session will be created and authenticationSuccessHandler will be invoked which redirects to the target url configured(default is /)
   • If authentication failed user becomes un-authenticated user and chain continues.

6. SecurityContextHolderAwareRequestFilter, if you are using it to install a Spring Security aware HttpServletRequestWrapper into your servlet container

7. AnonymousAuthenticationFilter Detects if there is no Authentication object in the SecurityContextHolder, if no authentication object found, creates Authentication object (AnonymousAuthenticationToken) with granted authority ROLE_ANONYMOUS. Here AnonymousAuthenticationToken facilitates identifying un-authenticated users subsequent requests.
   

DEBUG - /app/admin/app-config at position 9 of 12 in additional filter chain; firing Filter: 'AnonymousAuthenticationFilter'
DEBUG - Populated SecurityContextHolder with anonymous token: 'org.springframework.security.authentication.AnonymousAuthenticationToken@aeef7b36: Principal: anonymousUser; Credentials: [PROTECTED]; Authenticated: true; Details: org.springframework.security.web.authentication.WebAuthenticationDetails@b364: RemoteIpAddress: 0:0:0:0:0:0:0:1; SessionId: null; Granted Authorities: ROLE_ANONYMOUS' 

8. ExceptionTranslationFilter, to catch any Spring Security exceptions so that either an HTTP error response can be returned or an appropriate AuthenticationEntryPoint can be launched

9. FilterSecurityInterceptor
   There will be FilterSecurityInterceptor which comes almost last in the filter chain which gets Authentication object from SecurityContext and gets granted authorities list(roles granted) and it will make a decision whether to allow this request to reach the requested resource or not, decision is made by matching with the allowed AntMatchers configured in HttpSecurityConfiguration.

Consider the exceptions 401-UnAuthorized and 403-Forbidden. These decisions will be done at the last in the filter chain

• Un authenticated user trying to access public resource - Allowed
  
• Un authenticated user trying to access secured resource - 401-UnAuthorized
  
• Authenticated user trying to access restricted resource(restricted for his role) - 403-Forbidden
  

Note: User Request flows not only in above mentioned filters, but there are others filters too not shown here.(ConcurrentSessionFilter,RequestCacheAwareFilter,SessionManagementFilter ...)
It will be different when you use your custom auth filter instead of UsernamePasswordAuthenticationFilter.
It will be different if you configure JWT auth filter and omit .formLogin() i.e, UsernamePasswordAuthenticationFilter it will become entirely different case.

From Documentation ordering of filters is given as

• ChannelProcessingFilter
• ConcurrentSessionFilter
• SecurityContextPersistenceFilter
• LogoutFilter
• X509AuthenticationFilter
• AbstractPreAuthenticatedProcessingFilter
• CasAuthenticationFilter
• UsernamePasswordAuthenticationFilter
• ConcurrentSessionFilter
• OpenIDAuthenticationFilter
• DefaultLoginPageGeneratingFilter
• DefaultLogoutPageGeneratingFilter
• ConcurrentSessionFilter
• DigestAuthenticationFilter
• BearerTokenAuthenticationFilter
• BasicAuthenticationFilter
• RequestCacheAwareFilter
• SecurityContextHolderAwareRequestFilter
• JaasApiIntegrationFilter
• RememberMeAuthenticationFilter
• AnonymousAuthenticationFilter
• SessionManagementFilter
• ExceptionTranslationFilter
• FilterSecurityInterceptor
• SwitchUserFilter

ZoneId americaLaPazZone = ZoneId.of("UTC-04:00");

static Date firstDateOfMonth(Date date) {
  LocalDate localDate = convertToLocalDateWithTimezone(date);
  YearMonth baseMonth = YearMonth.from(localDate);
  LocalDateTime initialDate = baseMonth.atDay(firstDayOfMonth).atStartOfDay();
  return Date.from(initialDate.atZone(americaLaPazZone).toInstant());
}

static Date lastDateOfMonth(Date date) {
  LocalDate localDate = convertToLocalDateWithTimezone(date);
  YearMonth baseMonth = YearMonth.from(localDate);
  LocalDateTime lastDate = baseMonth.atEndOfMonth().atTime(23, 59, 59);
  return Date.from(lastDate.atZone(americaLaPazZone).toInstant());

You can stash (save the changes in temporary box) then, back to master branch HEAD.

$ git add .
$ git stash
$ git checkout master

Jump Over Commits Back and Forth:

• Go to a specific commit-sha.

    $ git checkout <commit-sha>
  

• If you have uncommitted changes here then, you can checkout to a new branch | Add | Commit | Push the current branch to the remote.

    # checkout a new branch, add, commit, push
    $ git checkout -b <branch-name>
    $ git add .
    $ git commit -m 'Commit message'
    $ git push origin HEAD          # push the current branch to remote 
  
    $ git checkout master           # back to master branch now
  

• If you have changes in the specific commit and don't want to keep the changes, you can do stash or reset then checkout to master (or, any other branch).

    # stash
    $ git add -A
    $ git stash
    $ git checkout master
  
    # reset
    $ git reset --hard HEAD
    $ git checkout master
  

• After checking out a specific commit if you have no uncommitted change(s) then, just back to master or other branch.

    $ git status          # see the changes
    $ git checkout master
  
    # or, shortcut
    $ git checkout -      # back to the previous state

}

You have to use CSS.

In my opinion when you have a table often it is good with a separate line each side of the line.

Try this code:

HTML:

<table>
    <tr class="row"><td>row 1</td></tr>
    <tr class="row"><td>row 2</td></tr>
</table>

CSS:

.row {
    border:1px solid black; 
}

There are 3 things you need.

1. You need to oAuth with the owner of those photos. (with the 'user_photos' extended permission)

2. You need the access token (which you get returned in the URL box after the oAuth is done.)

3. When those are complete you can then access the photos like so https://graph.facebook.com/me?access_token=ACCESS_TOKEN

You can find all of the information in more detail here: http://developers.facebook.com/docs/authentication

The correct syntax is:

FOR EACH ROW SET NEW.bname = CONCAT( UCASE( LEFT( NEW.bname, 1 ) )
                                   , LCASE( SUBSTRING( NEW.bname, 2 ) ) )

This code should work for you:

Comment.find(:all, :conditions => {:created_at => @selected_date.beginning_of_day..@selected_date.end_of_day})

For more info have a look at Time calculations

Note: This code is deprecated. Use the code from the answer if you are using Rails 3.1/3.2

If you are writing a scraper and really don't care about the SSL certificate you can set it global:

import ssl

ssl._create_default_https_context = ssl._create_unverified_context

DO NOT USE IN PRODUCTION

I tried most of the solutions to this problem but couldn't get any to work.

I ran lsof -P | grep ':5432' | awk '{print $2}' which showed the PID of the process running. However I couldn't kill it with kill -9 <pid>.

When I ran pkill postgresql the process finally stopped. Hope this helps.

I have made a bash script related to the same to check if the certificate is expired or not. You can use the same if required.

its too simple, you can just type "cache:" before the URL of the page. for example if you want to check the last webcache of this page simply type on URL bar cache:http://stackoverflow.com/questions/4560400/how-can-i-get-the-google-cache-age-of-any-url-or-web-page

this will show you the last webcache of the page.see here:

But remember, the caching of a webpage will only show if the page is already indexed on search engine(Google). for this you need to check the meta robot tag of that page.

If you need a progmatic solution this should work in jQuery:

$(".abc.xyz").css("width", 200);

If you are using SQL Server 2016 or above, you can use sp_execute_external_script along with R. It has functions for Regular Expression searches, such as grep and grepl.

Here's an example for email addresses. I'll query some "people" via the SQL Server database engine, pass the data for those people to R, let R decide which people have invalid email addresses, and have R pass back that subset of people to SQL Server. The "people" are from the [Application].[People] table in the [WideWorldImporters] sample database. They get passed to the R engine as a dataframe named InputDataSet. R uses the grepl function with the "not" operator (exclamation point!) to find which people have email addresses that don't match the RegEx string search pattern.

EXEC sp_execute_external_script 
 @language = N'R',
 @script = N' RegexWithR <- InputDataSet;
OutputDataSet <- RegexWithR[!grepl("([_a-z0-9-]+(\\.[_a-z0-9-]+)*@[a-z0-9-]+(\\.[a-z0-9-]+)*(\\.[a-z]{2,4}))", RegexWithR$EmailAddress), ];',
 @input_data_1 = N'SELECT PersonID, FullName, EmailAddress FROM Application.People'
 WITH RESULT SETS (([PersonID] INT, [FullName] NVARCHAR(50), [EmailAddress] NVARCHAR(256)))

Note that the appropriate features must be installed on the SQL Server host. For SQL Server 2016, it is called "SQL Server R Services". For SQL Server 2017, it was renamed to "SQL Server Machine Learning Services".

Closing Thoughts Microsoft's implementation of SQL (T-SQL) doesn't have native support for RegEx. This proposed solution may not be any more desirable to the OP than the use of a CLR stored procedure. But it does offer an additional way to approach the problem.

You need to use brackets if the property names has special characters:

var foo = {
    "Hello, world!": true,
}
foo["Hello, world!"] = false;

Other than that, I suppose it's just a matter of taste. IMHO, the dot notation is shorter and it makes it more obvious that it's a property rather than an array element (although of course JavaScript does not have associative arrays anyway).

In your Manifest type this:

<activity
    android:screenOrientation="portrait"
    <!--- Rest of your application information ---!>
</activity>

Try

use an id for hidden field and use id of checkbox in javascript.

and change the ClientIDMode="static" too

<input type="hidden" ClientIDMode="static" id="label1" name="label206451" value="0" />

   <script type="text/javascript"> 
    var cb = document.getElementById('txt206451');
    var label = document.getElementById('label1');
    cb.addEventListener('click',function(evt){
    if(cb.checked){
        label.value='Thanks'
    }else{
        label.value='0'
    }
    },false);
    </script>

Limit - 30 symbols. Username must contains only letters, numbers, periods and underscores.

var content = fs.readFileSync('test.txt', 'utf8');

Use the find command,

find . -type f -name "*John*"

There are two answers , First is use 'sep' setting

>>> print(*names, sep = ', ')

The other is below

You can use mb_chars. This respects umlaute:

class String

  # Only capitalize first letter of a string
  def capitalize_first
    self[0] = self[0].mb_chars.upcase
    self
  end

end

Example:

"ümlaute".capitalize_first
#=> "Ümlaute"

I had the same problem in Catalina.sh of my tomcat for JPDA Options:

JPDA_OPTS="-agentlib:jdwp=transport=$JPDA_TRANSPORT,address=$JPDA_ADDRESS,server=y,suspend=$JPDA_SUSPEND"

After removing JPDA option from my command to start the Tomcat server, I was able to start the server on local environment.

DateTime has a Subtract method and an overloaded - operator for just such an occasion:

DateTime now = DateTime.UtcNow;
TimeSpan difference = now.Subtract(otherTime); // could also write `now - otherTime`
if (difference.TotalSeconds > 5) { ... }

Go into your project structure, under project Settings, Modules, select the dependencies table. For each dependency, change the scope from 'Test' to 'Compile'.

I do not like java type names in query strings and handle it with a specific constructor. Spring JPA implicitly calls constructor with query result in HashMap parameter:

@Getter
public class SurveyAnswerStatistics {
  public static final String PROP_ANSWER = "answer";
  public static final String PROP_CNT = "cnt";

  private String answer;
  private Long   cnt;

  public SurveyAnswerStatistics(HashMap<String, Object> values) {
    this.answer = (String) values.get(PROP_ANSWER);
    this.count  = (Long) values.get(PROP_CNT);
  }
}

@Query("SELECT v.answer as "+PROP_ANSWER+", count(v) as "+PROP_CNT+" FROM  Survey v GROUP BY v.answer")
List<SurveyAnswerStatistics> findSurveyCount();

Code needs Lombok for resolving @Getter

This is what you need in 1 line of code.

Route::get('/groups/{groupId}', 'GroupsController@getShow');

Suggestion: Use CamelCase as opposed to underscores, try & follow PSR-* guidelines.

Hope it helps.

I solved this problem on Github separating the indented sub-block with a newline, for instance, you write the item 1, then hit enter twice (like if it was a new paragraph), indent the block and write what you want (a block of code, text, etc). More information on Markdown lists and Markdown line breaks.

Example:

1. item one

2. item two

   this block acts as a new paragraph, above there is a blank line

3. item three

   some other code

4. item four

put your images in the public folder or make a subfolder in your public folder and put your images there. for example:

1. you put "completative-reptile.jpg" in the public folder, then you can access it as

src={'/completative-reptile.jpg'}

2. you put completative-reptile.jpg at public/static/images, then you can access it as

src={'/static/images/completative-reptile.jpg'}

In addition to the accepted answer by @Andreas Mueller, just want to add that as @tangy mentioned above:

StratifiedShuffleSplit most closely resembles train_test_split(stratify = y) with added features of:

1. stratify by default
2. by specifying n_splits, it repeatedly splits the data

Why not try MySQL GUI Tools? It's light, and does its job well.

You may have different sets of checkboxes on the same form. Here is a solution that selects/unselects checkboxes by class name, using vanilla javascript function document.getElementsByClassName

The Select All button

<input type='checkbox' id='select_all_invoices' onclick="selectAll()"> Select All

Some of the checkboxes to select

<input type='checkbox' class='check_invoice' id='check_123' name='check_123' value='321' />
<input type='checkbox' class='check_invoice' id='check_456' name='check_456' value='852' />

The javascript

    function selectAll() {
        var blnChecked = document.getElementById("select_all_invoices").checked;
        var check_invoices = document.getElementsByClassName("check_invoice");
        var intLength = check_invoices.length;
        for(var i = 0; i < intLength; i++) {
            var check_invoice = check_invoices[i];
            check_invoice.checked = blnChecked;
        }
    }

With SmartGit, you can also edit them by going to Project > Repository settings and hitting the "Commit" tab (make sure to have "Remember as default" selected).

My resolution was running adb devices from the command prompt, pathed to the adb application. For example C:\Android\platform-tools\adb devices . Running this command returned the following * daemon not running. starting it now on port 5037 * *daemon started successfully *

I then saw the device listed as unauthorized, unplugges the USB, plugged back in and was prompted for the RSA fingerprint.

What about running the google-drive-ftp-adapter application in your local pc and then connect your filezilla client to that application? The google-drive-ftp-adapter application is not an online service, but its an alternative solution to connect to google drive through ftp.

The google-drive-ftp-adapter is an open source application hosted in github and it is a kind of standalone ftp-server java application that connects to your google drive in behalf of you, acting as a bridge (or adapter) between your ftp client and the google drive service. Once you have running the google-drive-ftp adapter, you can connect your preferred FTP client to the google-drive-ftp-adapter ftp server in your localhost (or wherever the app is running, like in a remote machine) to manage your files.

I use it in conjunction with beyond compare to synchronize my local files against the ones I have in the google drive and it serves well for the purpose.

This is the current github link hosting the google-drive-ftp-adapter repository: https://github.com/andresoviedo/google-drive-ftp-adapter

#include <signal.h>
#include <stdlib.h>
#include <stdio.h>

void my_handler(sig_t s){
           printf("Caught signal %d\n",s);
           exit(1); 

}

int main(int argc,char** argv)
{
   signal (SIGINT,my_handler);

   while(1);
   return 0;

}

Unlike languages that employ 'true' lexical scoping, Python opts to have specific 'namespaces' for variables, whether it be global, nonlocal, or local. It could be argued that making developers consciously code with such namespaces in mind is more explicit, thus more understandable. I would argue that such complexities make the language more unwieldy, but I guess it's all down to personal preference.

Here are some examples regarding global:-

>>> global_var = 5
>>> def fn():
...     print(global_var)
... 
>>> fn()
5
>>> def fn_2():
...     global_var += 2
...     print(global_var)
... 
>>> fn_2()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 2, in fn_2
UnboundLocalError: local variable 'global_var' referenced before assignment
>>> def fn_3():
...     global global_var
...     global_var += 2
...     print(global_var)
... 
>>> fn_3()
7

The same patterns can be applied to nonlocal variables too, but this keyword is only available to the latter Python versions.

In case you're wondering, nonlocal is used where a variable isn't global, but isn't within the function definition it's being used. For example, a def within a def, which is a common occurrence partially due to a lack of multi-statement lambdas. There's a hack to bypass the lack of this feature in the earlier Pythons though, I vaguely remember it involving the use of a single-element list...

Note that writing to variables is where these keywords are needed. Just reading from them isn't ambiguous, thus not needed. Unless you have inner defs using the same variable names as the outer ones, which just should just be avoided to be honest.

var myTestApp = angular.module("myTestApp", []); 
myTestApp.controller("myTestController", function($scope, $window) {
$window.onload = function() {
 alert("is called on page load.");
};
});

If you can add an extra couple of divs so your html looks like this:

<div id="wrapper">
    <div id="first" class="row">
        <div class="cell"></div>
    </div>
    <div id="second" class="row">
        <div class="cell"></div>
    </div>
</div>

You can make use of the display:table properties:

#wrapper
{
   width:300px;
   height:100%;
   display:table;
}

.row 
{
   display:table-row;
}

.cell 
{
   display:table-cell;
}

#first .cell
{
   height:200px;
   background-color:#F5DEB3;
}

#second .cell
{
   background-color:#9ACD32;
}

Example

To save time writing for check new version update for android app, I written it as library and open source at https://github.com/winsontan520/Android-WVersionManager

change table column < id > to < _id >

 String LastId = "id";

    database.execSQL("ALTER TABLE " + PhraseContract.TABLE_NAME + " RENAME TO " + PhraseContract.TABLE_NAME + "old");
    database.execSQL("CREATE TABLE " + PhraseContract.TABLE_NAME
    +"("
            + PhraseContract.COLUMN_ID + " INTEGER PRIMARY KEY,"
            + PhraseContract.COLUMN_PHRASE + " text ,"
            + PhraseContract.COLUMN_ORDER  + " text ,"
            + PhraseContract.COLUMN_FROM_A_LANG + " text"
    +")"
    );
    database.execSQL("INSERT INTO " +
            PhraseContract.TABLE_NAME + "("+ PhraseContract.COLUMN_ID +" , "+ PhraseContract.COLUMN_PHRASE + " , "+ PhraseContract.COLUMN_ORDER +" , "+ PhraseContract.COLUMN_FROM_A_LANG +")" +
            " SELECT " + LastId +" , "+ PhraseContract.COLUMN_PHRASE + " , "+ PhraseContract.COLUMN_ORDER +" , "+ PhraseContract.COLUMN_FROM_A_LANG +
            " FROM " + PhraseContract.TABLE_NAME + "old");
    database.execSQL("DROP TABLE " + PhraseContract.TABLE_NAME + "old");

In short no. It is generally thought to be too dangerous to rename a database. MySQL had that feature for a bit, but it was removed. You would be better off using the workbench to export both the schema and data to SQL then changing the CREATE DATABASE name there before you run/import it.

This Facebook page has a simple tool to create various share buttons.

For example, this is some output I got:

<div id="fb-root"></div>
<script async defer crossorigin="anonymous" src="https://connect.facebook.net/en_US/sdk.js#xfbml=1&version=v8.0" nonce="dilSYGI6"></script>

for Z score, we can stick to documentation instead of using 'apply' function

from scipy.stats import zscore
df_zscore = zscore(cols as array, axis=1)

I do this using associative arrays since bash 4 and setting IFS to a value that can be defined manually.

The purpose of this approach is to have arrays as values of associative array keys.

In order to set IFS back to default just unset it.

• unset IFS

This is an example:

#!/bin/bash

set -euo pipefail

# used as value in asscciative array
test=(
  "x3:x4:x5"
)
# associative array
declare -A wow=(
  ["1"]=$test
  ["2"]=$test
)
echo "default IFS"
for w in ${wow[@]}; do
  echo "  $w"
done

IFS=:
echo "IFS=:"
for w in ${wow[@]}; do
  for t in $w; do
    echo "  $t"
  done
done
echo -e "\n or\n"
for w in ${!wow[@]}
do
  echo "  $w"
  for t in ${wow[$w]}
  do
    echo "    $t"
  done
done

unset IFS
unset w
unset t
unset wow
unset test

The output of the script below is:

default IFS
  x3:x4:x5
  x3:x4:x5
IFS=:
  x3
  x4
  x5
  x3
  x4
  x5

 or

  1
    x3
    x4
    x5
  2
    x3
    x4
    x5

The short and clear explanation about Reactive Programming appears on Cyclejs - Reactive Programming, it uses simple and visual samples.

A [module/Component/object] is reactive means it is fully responsible for managing its own state by reacting to external events.

What is the benefit of this approach? It is Inversion of Control, mainly because [module/Component/object] is responsible for itself, improving encapsulation using private methods against public ones.

It is a good startup point, not a complete source of knowlege. From there you could jump to more complex and deep papers.

A version of Otto Nascarella's solution that works in strict mode is:

button.addEventListener('click', function handler() {
      ///this will execute only once
      alert('only once!');
      this.removeEventListener('click', handler);
});

To read a particular date from range EJ_PAYDATES_2021 (index is next to the last "1")

=INDEX(PayDates.xlsx!EJ_PAYDATES_2021,1,1)  // Jan
=INDEX(PayDates.xlsx!EJ_PAYDATES_2021,2,1)  // Feb
=INDEX(PayDates.xlsx!EJ_PAYDATES_2021,3,1)  // Mar

This allows reading a particular element of a range [0] etc from another spreadsheet file. Target file need not be open. Range in the above example is named EJ_PAYDATES_2021, with one element for each month contained within that range.

Took me a while to parse this out, but it works, and is the answer to the question asked above.

There're two kind of Django "projects" that I have in my ~/projects/ directory, both have a bit different structure.:

• Stand-alone websites
• Pluggable applications

Stand-alone website

Mostly private projects, but doesn't have to be. It usually looks like this:

~/projects/project_name/

docs/               # documentation
scripts/
  manage.py         # installed to PATH via setup.py
project_name/       # project dir (the one which django-admin.py creates)
  apps/             # project-specific applications
    accounts/       # most frequent app, with custom user model
    __init__.py
    ...
  settings/         # settings for different environments, see below
    __init__.py
    production.py
    development.py
    ...
        
  __init__.py       # contains project version
  urls.py
  wsgi.py
static/             # site-specific static files
templates/          # site-specific templates
tests/              # site-specific tests (mostly in-browser ones)
tmp/                # excluded from git
setup.py
requirements.txt
requirements_dev.txt
pytest.ini
...

Settings

The main settings are production ones. Other files (eg. staging.py, development.py) simply import everything from production.py and override only necessary variables.

For each environment, there are separate settings files, eg. production, development. I some projects I have also testing (for test runner), staging (as a check before final deploy) and heroku (for deploying to heroku) settings.

Requirements

I rather specify requirements in setup.py directly. Only those required for development/test environment I have in requirements_dev.txt.

Some services (eg. heroku) requires to have requirements.txt in root directory.

setup.py

Useful when deploying project using setuptools. It adds manage.py to PATH, so I can run manage.py directly (anywhere).

Project-specific apps

I used to put these apps into project_name/apps/ directory and import them using relative imports.

Templates/static/locale/tests files

I put these templates and static files into global templates/static directory, not inside each app. These files are usually edited by people, who doesn't care about project code structure or python at all. If you are full-stack developer working alone or in a small team, you can create per-app templates/static directory. It's really just a matter of taste.

The same applies for locale, although sometimes it's convenient to create separate locale directory.

Tests are usually better to place inside each app, but usually there is many integration/functional tests which tests more apps working together, so global tests directory does make sense.

Tmp directory

There is temporary directory in project root, excluded from VCS. It's used to store media/static files and sqlite database during development. Everything in tmp could be deleted anytime without any problems.

Virtualenv

I prefer virtualenvwrapper and place all venvs into ~/.venvs directory, but you could place it inside tmp/ to keep it together.

Project template

I've created project template for this setup, django-start-template

Deployment

Deployment of this project is following:

source $VENV/bin/activate
export DJANGO_SETTINGS_MODULE=project_name.settings.production
git pull
pip install -r requirements.txt

# Update database, static files, locales
manage.py syncdb  --noinput
manage.py migrate
manage.py collectstatic --noinput
manage.py makemessages -a
manage.py compilemessages

# restart wsgi
touch project_name/wsgi.py

You can use rsync instead of git, but still you need to run batch of commands to update your environment.

Recently, I made django-deploy app, which allows me to run single management command to update environment, but I've used it for one project only and I'm still experimenting with it.

Sketches and drafts

Draft of templates I place inside global templates/ directory. I guess one can create folder sketches/ in project root, but haven't used it yet.

Pluggable application

These apps are usually prepared to publish as open-source. I've taken example below from django-forme

~/projects/django-app/

docs/
app/
tests/
example_project/
LICENCE
MANIFEST.in
README.md
setup.py
pytest.ini
tox.ini
.travis.yml
...

Name of directories is clear (I hope). I put test files outside app directory, but it really doesn't matter. It is important to provide README and setup.py, so package is easily installed through pip.

For the length of 6, recursiveness doesn't matter a lot.

function random(len) {_x000D_
  let result = Math.floor(Math.random() * Math.pow(10, len));_x000D_
_x000D_
  return (result.toString().length < len) ? random(len) : result;_x000D_
}_x000D_
_x000D_
console.log(random(6));

You can see answers at here Get Android Phone Model Programmatically

public String getDeviceName() {
   String manufacturer = Build.MANUFACTURER;
   String model = Build.MODEL;
   if (model.startsWith(manufacturer)) {
      return capitalize(model);
   } else {
      return capitalize(manufacturer) + " " + model;
   }
}


private String capitalize(String s) {
    if (s == null || s.length() == 0) {
        return "";
    }
    char first = s.charAt(0);
    if (Character.isUpperCase(first)) {
        return s;
    } else {
        return Character.toUpperCase(first) + s.substring(1);
    }
}

Modulus operator; gives the remainder of the left value divided by the right value. Like:

3 % 1 would equal zero (since 3 divides evenly by 1)

3 % 2 would equal 1 (since dividing 3 by 2 results in a remainder of 1).

netstat -ano|grep 443|grep LISTEN

will tell you whether a process is listening on port 443 (you might have to replace LISTEN with a string in your language, though, depending on your system settings).

Easy solution. In a data frame with 5 columns, If you want insert another column between 3 and 4...

tmp <- data[, 1:3]
tmp$example <- NA # or any value.
data <- cbind(tmp, data[, 4:5]

You can do it by setting the aspect of the image manually (or by letting it auto-scale to fill up the extent of the figure).

By default, imshow sets the aspect of the plot to 1, as this is often what people want for image data.

In your case, you can do something like:

import matplotlib.pyplot as plt
import numpy as np

grid = np.random.random((10,10))

fig, (ax1, ax2, ax3) = plt.subplots(nrows=3, figsize=(6,10))

ax1.imshow(grid, extent=[0,100,0,1])
ax1.set_title('Default')

ax2.imshow(grid, extent=[0,100,0,1], aspect='auto')
ax2.set_title('Auto-scaled Aspect')

ax3.imshow(grid, extent=[0,100,0,1], aspect=100)
ax3.set_title('Manually Set Aspect')

plt.tight_layout()
plt.show()

If you use numpy, this is easy:

slice = arr[:2,:2]

or if you want the 0's,

slice = arr[0:2,0:2]

You'll get the same result.

*note that slice is actually the name of a builtin-type. Generally, I would advise giving your object a different "name".

Another way, if you're working with lists of lists*:

slice = [arr[i][0:2] for i in range(0,2)]

(Note that the 0's here are unnecessary: [arr[i][:2] for i in range(2)] would also work.).

What I did here is that I take each desired row 1 at a time (arr[i]). I then slice the columns I want out of that row and add it to the list that I'm building.

If you naively try: arr[0:2] You get the first 2 rows which if you then slice again arr[0:2][0:2], you're just slicing the first two rows over again.

*This actually works for numpy arrays too, but it will be slow compared to the "native" solution I posted above.

In the examples below the client is the browser and the server is the webserver hosting the website.

Before you can understand these technologies, you have to understand classic HTTP web traffic first.

Regular HTTP:

1. A client requests a webpage from a server.
2. The server calculates the response
3. The server sends the response to the client.

Ajax Polling:

1. A client requests a webpage from a server using regular HTTP (see HTTP above).
2. The client receives the requested webpage and executes the JavaScript on the page which requests a file from the server at regular intervals (e.g. 0.5 seconds).
3. The server calculates each response and sends it back, just like normal HTTP traffic.

Ajax Long-Polling:

1. A client requests a webpage from a server using regular HTTP (see HTTP above).
2. The client receives the requested webpage and executes the JavaScript on the page which requests a file from the server.
3. The server does not immediately respond with the requested information but waits until there's new information available.
4. When there's new information available, the server responds with the new information.
5. The client receives the new information and immediately sends another request to the server, re-starting the process.

HTML5 Server Sent Events (SSE) / EventSource:

1. A client requests a webpage from a server using regular HTTP (see HTTP above).
2. The client receives the requested webpage and executes the JavaScript on the page which opens a connection to the server.

3. The server sends an event to the client when there's new information available.

   • Real-time traffic from server to client, mostly that's what you'll need
   • You'll want to use a server that has an event loop
   • Connections with servers from other domains are only possible with correct CORS settings
   • If you want to read more, I found these very useful: (article), (article), (article), (tutorial).

HTML5 Websockets:

1. A client requests a webpage from a server using regular http (see HTTP above).
2. The client receives the requested webpage and executes the JavaScript on the page which opens a connection with the server.

3. The server and the client can now send each other messages when new data (on either side) is available.

   • Real-time traffic from the server to the client and from the client to the server
   • You'll want to use a server that has an event loop
   • With WebSockets it is possible to connect with a server from another domain.
   • It is also possible to use a third party hosted websocket server, for example Pusher or others. This way you'll only have to implement the client side, which is very easy!
   • If you want to read more, I found these very useful: (article), (article) (tutorial).

Comet:

Comet is a collection of techniques prior to HTML5 which use streaming and long-polling to achieve real time applications. Read more on wikipedia or this article.

Now, which one of them should I use for a realtime app (that I need to code). I have been hearing a lot about websockets (with socket.io [a node.js library]) but why not PHP ?

You can use PHP with WebSockets, check out Ratchet.

Try

<iframe src="url" style="border:none;"></iframe>

This will remove the border of your frame.

Try this:

NSString *URL = @"xyz.com";
if([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:URL]])
{
     [[UIApplication sharedApplication] openURL:[NSURL URLWithString:URL]];
}

Whenever I go through input and want to remove or replace characters I run it through little subroutines like this one.

sub clean {

    my $text = shift;

    $text =~ s/\n//g;
    $text =~ s/\r//g;

    return $text;
}

It may not be fancy but this method has been working flawless for me for years.

You can use a heredoc. e.g. from a prompt:

$ sqlplus -s username/password@oracle_instance <<EOF
set feed off
set pages 0
select count(*) from table;
exit
EOF

so sqlplus will consume everything up to the EOF marker as stdin.

You can use find

find . -type d > output.txt

or tree

tree -d > output.txt

tree, If not installed on your system.

If you are using ubuntu

sudo apt-get install tree

If you are using mac os.

brew install tree

var defaultSettings = {
    ajaxsettings: {},
    uisettings: {}
};

Take a look at this site: http://www.json.org/

Also, you can try calling JSON.stringify() on one of your objects from the browser to see the json format. You'd have to do this in the console or a test page.

You can use window.location.reload(); in your componentDidMount() lifecycle method. If you are using react-router, it has a refresh method to do that.

Edit: If you want to do that after a data update, you might be looking to a re-render not a reload and you can do that by using this.setState(). Here is a basic example of it to fire a re-render after data is fetched.

import React from 'react'

const ROOT_URL = 'https://jsonplaceholder.typicode.com';
const url = `${ROOT_URL}/users`;

class MyComponent extends React.Component {
    state = {
        users: null
    }
    componentDidMount() {
        fetch(url)
            .then(response => response.json())
            .then(users => this.setState({users: users}));
    }
    render() {
        const {users} = this.state;
        if (users) {
            return (
                <ul>
                    {users.map(user => <li>{user.name}</li>)}
                </ul>
            )
        } else {
            return (<h1>Loading ...</h1>)
        }
    }
}

export default MyComponent;

HTML5 introduces FormData class that can be used to file upload with ajax.

FormData support starts from following desktop browsers versions. IE 10+, Firefox 4.0+, Chrome 7+, Safari 5+, Opera 12+

FormData - Mozilla.org

With Git 2.15 (Q4 2017), "git branch" learned "-c/-C" to create a new branch by copying an existing one.

See commit c8b2cec (18 Jun 2017) by Ævar Arnfjörð Bjarmason (avar).
See commit 52d59cc, commit 5463caa (18 Jun 2017) by Sahil Dua (sahildua2305).
^{(Merged by Junio C Hamano -- gitster -- in commit 3b48045, 03 Oct 2017)}

branch: add a --copy (-c) option to go with --move (-m)

Add the ability to --copy a branch and its reflog and configuration, this uses the same underlying machinery as the --move (-m) option except the reflog and configuration is copied instead of being moved.

This is useful for e.g. copying a topic branch to a new version, e.g. work to work-2 after submitting the work topic to the list, while preserving all the tracking info and other configuration that goes with the branch, and unlike --move keeping the other already-submitted branch around for reference.

Note: when copying a branch, you remain on your current branch.
As Junio C Hamano explains, the initial implementation of this new feature was modifying HEAD, which was not good:

When creating a new branch B by copying the branch A that happens to be the current branch, it also updates HEAD to point at the new branch.
It probably was made this way because "git branch -c A B" piggybacked its implementation on "git branch -m A B",

This does not match the usual expectation.
If I were sitting on a blue chair, and somebody comes and repaints it to red, I would accept ending up sitting on a chair that is now red (I am also OK to stand, instead, as there no longer is my favourite blue chair).

But if somebody creates a new red chair, modelling it after the blue chair I am sitting on, I do not expect to be booted off of the blue chair and ending up on sitting on the new red one.

Having tried other solutions which worked fine, but the pitfall of their answers is that only fields already existing would update adding upsert to it would do nothing, so I came up with this.

 Person.update({'items.id': 2}, {$set: {
    'items': { "item1",  "item2",  "item3",  "item4" } }, {upsert: 
true })

Use : instead of =

see the example below that gives an error

app.post('/mews', (req, res) => {
if (isValidMew(req.body)) {
    // insert into db
    const mew = {
        name = filter.clean(req.body.name.toString()),
        content = filter.clean(req.body.content.toString()),
        created: new Date()
    };

That gives Syntex Error: invalid shorthand proprty initializer.

Then i replace = with : that's solve this error.

app.post('/mews', (req, res) => {
if (isValidMew(req.body)) {
    // insert into db
    const mew = {
        name: filter.clean(req.body.name.toString()),
        content: filter.clean(req.body.content.toString()),
        created: new Date()
    };

Your HTML:

<div class="img-with-text">
    <img src="yourimage.jpg" alt="sometext" />
    <p>Some text</p>
</div>

If you know the width of your image, your CSS:

.img-with-text {
    text-align: justify;
    width: [width of img];
}

.img-with-text img {
    display: block;
    margin: 0 auto;
}

Otherwise your text below the image will free-flow. To prevent this, just set a width to your container.

Do not include bin in your JAVA_HOME env variable

Here's the GNU version of printf... you can see it passing in stdout to vfprintf:

__printf (const char *format, ...)
{
   va_list arg;
   int done;

   va_start (arg, format);
   done = vfprintf (stdout, format, arg);
   va_end (arg);

   return done;
}

See here.

Here's a link to vfprintf... all the formatting 'magic' happens here.

The only thing that's truly 'different' about these functions is that they use varargs to get at arguments in a variable length argument list. Other than that, they're just traditional C. (This is in contrast to Pascal's printf equivalent, which is implemented with specific support in the compiler... at least it was back in the day.)

A little bit late, but all the answers were specific to linux.

If you need also unix, then you need this:

char * getExecPath (char * path,size_t dest_len, char * argv0)
{
    char * baseName = NULL;
    char * systemPath = NULL;
    char * candidateDir = NULL;

    /* the easiest case: we are in linux */
    size_t buff_len;
    if (buff_len = readlink ("/proc/self/exe", path, dest_len - 1) != -1)
    {

Having had a similar itch to scratch (altough only for some files of a given repository) this script proved to be really helpful: git-import

The short version is that it creates patch files of the given file or directory ($object) from the existing repository:

cd old_repo
git format-patch --thread -o "$temp" --root -- "$object"

which then get applied to a new repository:

cd new_repo
git am "$temp"/*.patch 

For details please look up:

• the documented source
• git format-patch
• git am

val.ToString("".PadLeft(length, '0'))

The property event.key gave me an undefined value. Instead, I used event.keyCode:

function alphaOnly(event) {
  var key = event.keyCode;
  return ((key >= 65 && key <= 90) || key == 8);
};

Note that the value of 8 is for the backspace key.

Cookies are Client-side and cannot be tested properly using PHP. That's the baseline and every solution is a wrap-around for this problem.

Meaning if you are looking a solution for your cookie problem, you are on the wrong way. Don'y use PHP, use a client language like Javascript.

Can you use cookies using PHP? Yes, but you have to reload to make the settings to PHP 'visible'.

For instance: Is a test possible to see if the browser can set Cookies with plain PHP'. The only correct answer is 'NO'.

Can you read an already set Cookie: 'YES' use the predefined $_COOKIE (A copy of the settings before you started PHP-App).

One option is to directly input the character you're interested in using hex or octal notation:

printf "\x41\n"
printf "\101\n"

DATEDIFF(d, 'Start Date', 'End Date')

do it

We can Supply parameter in different way after some search I found some useful

<plugin>
  <artifactId>${release.artifactId}</artifactId>
  <version>${release.version}-${release.svm.version}</version>...

...

Actually in my application I need to save and supply SVN Version as parameter so i have implemented as above .

While Running build we need supply value for those parameter as follows.

RestProj_Bizs>mvn clean install package -Drelease.artifactId=RestAPIBiz -Drelease.version=10.6 -Drelease.svm.version=74

Here I am supplying

release.artifactId=RestAPIBiz
release.version=10.6
release.svm.version=74

It worked for me. Thanks

Image to Data:-

    if let img = UIImage(named: "xxx.png") {
        let pngdata = img.pngData()
    }

   if let img = UIImage(named: "xxx.jpeg") {
        let jpegdata = img.jpegData(compressionQuality: 1)
    }

Data to Image:-

 let image = UIImage(data: pngData)

If, for example, x = 5 and is stored as string, you can also just:

x = x + 0

and the new x would be stored as a numeric value.

Another way to do it would be to inspect the url bar in chrome to find the id of the element, have your WebDriver click that element, and then send the keys you use to copy and paste using the keys common function from selenium, and then printing it out or storing it as a variable, etc.

Here is a more flexible solution using a closure:

$my_array = array("foo" => 1, "hello" => "world");
$allowed = array("foo", "bar");
$result = array_flip(array_filter(array_flip($my_array), function ($key) use ($allowed)
{
    return in_array($key, $allowed);
}));
var_dump($result);

Outputs:

array(1) {
  'foo' =>
  int(1)
}

So in the function, you can do other specific tests.

Not really an answer to the specific question, but if there are others, like me, who are getting this error in fastAPI and end up here:

It is probably because your route response has a value that can't be JSON serialised by jsonable_encoder. For me it was WKBElement: https://github.com/tiangolo/fastapi/issues/2366

Like in the issue, I ended up just removing the value from the output.

This should work for you:

public int Get4LetterYear(int twoLetterYear)
{
    int firstTwoDigits =
        Convert.ToInt32(DateTime.Now.Year.ToString().Substring(2, 2));
    return Get4LetterYear(twoLetterYear, firstTwoDigits);
}

public int Get4LetterYear(int twoLetterYear, int firstTwoDigits)
{
    return Convert.ToInt32(firstTwoDigits.ToString() + twoLetterYear.ToString());
}

public int Get2LetterYear(int fourLetterYear)
{
    return Convert.ToInt32(fourLetterYear.ToString().Substring(2, 2));
}

I don't think there are any special built-in stuff in .NET.

Update: It's missing some validation that you maybe should do. Validate length of inputted variables, and so on.

As Hogan notes above, use an AND instead of &. See this tutorial for more info.

This is pretty clear, actually. Many folks learn it quickly. You can use a comment to help them.

The content of all stored procedures, views and functions are stored in field text of table sysComments. The name of all objects are stored in table sysObjects and the columns are in sysColumns.

Having this information, you can use this code to search in content of views, stored procedures, and functions for the specified word:

Select b.name from syscomments a
inner join sysobjects b on a.id = b.id
where text like '%tblEmployes%'

This query will give you the objects which contains the word "tblEmployes" .

To search by the name of Objects you can use this code:

Select name from sysobjects
where name like  '%tblEmployes%'

And finally to find the objects having at least one column containing the word "tblEmployes", you can use this code:

Select b.name from syscolumns a inner join sysobjects b on a.id = b.id
where a.name like  '%tblEmployes%'

You can combine these three queries with union:

Select distinct b.name from syscomments a
inner join sysobjects b on a.id = b.id
where text like '%tblEmployes%'
union
Select distinct name from sysobjects
where name like  '%tblEmployes%'
union
Select distinct b.name from syscolumns a inner join sysobjects b on a.id = b.id
where a.name like  '%tblEmployes%'

With this query you have all objects containing the word "tblEmployes" in content or name or as a column.

For me it got resolved using following link: http://viralpatel.net/blogs/wamp-server-not-getting-started-problem/

Use elevation instead of zIndex for android devices

This worked fine for me!

There are two ways to connect remote redis server using redis-cli:

1. Using host & port individually as options in command

redis-cli -h host -p port

If your instance is password protected

redis-cli -h host -p port -a password

e.g. if my-web.cache.amazonaws.com is the host url and 6379 is the port

Then this will be the command:

redis-cli -h my-web.cache.amazonaws.com -p 6379

if 92.101.91.8 is the host IP address and 6379 is the port:

redis-cli -h 92.101.91.8 -p 6379

command if the instance is protected with password pass123:

redis-cli -h my-web.cache.amazonaws.com -p 6379 -a pass123

2. Using single uri option in command

redis-cli -u redis://password@host:port

command in a single uri form with username & password

redis-cli -u redis://username:password@host:port

e.g. for the same above host - port configuration command would be

redis-cli -u redis://[email protected]:6379

command if username is also provided user123

redis-cli -u redis://user123:[email protected]:6379

This detailed answer was for those who wants to check all options. For more information check documentation: Redis command line usage

No, you can't. JavaScript is executed on the client side (browser), while the session data is stored on the server.

However, you can expose session variables for JavaScript in several ways:

• a hidden input field storing the variable as its value and reading it through the DOM API
• an HTML5 data attribute which you can read through the DOM
• storing it as a cookie and accessing it through JavaScript
• injecting it directly in the JS code, if you have it inline

In JSP you'd have something like:

<input type="hidden" name="pONumb" value="${sessionScope.pONumb} />

or:

<div id="product" data-prodnumber="${sessionScope.pONumb}" />

Then in JS:

// you can find a more efficient way to select the input you want
var inputs = document.getElementsByTagName("input"), len = inputs.length, i, pONumb;
for (i = 0; i < len; i++) {
    if (inputs[i].name == "pONumb") {
        pONumb = inputs[i].value;
        break;
    }
}

or:

var product = document.getElementById("product"), pONumb;
pONumb = product.getAttribute("data-prodnumber");

The inline example is the most straightforward, but if you then want to store your JavaScript code as an external resource (the recommended way) it won't be feasible.

<script>
    var pONumb = ${sessionScope.pONumb};
    [...]
</script>

Start the second activity with startActivityForResult and in the second activity return a value, that once in the onActivityResult method of the first activity closes the main application. I think this is the correct way Android does it.

This error may also be triggered by having the wrong .NET framework version selected as the default in IIS.

Click on the root node under the Connections view (on the left hand side), then select Change .NET Framework Version from the Actions view (on the right hand side), then select the appropriate .NET version from the dropdown list.

select ID from A where ID not in (select ID from B);

or

select ID from A except select ID from B;

Your second question:

delete from A where ID not in (select ID from B);

Try this

df.drop(df.iloc[:, 1:69], inplace=True, axis=1)

This works for me

You need to enable SSL in your PHP config. Load up php.ini and find a line with the following:

;extension=php_openssl.dll

Uncomment it. :D

(by removing the semicolon from the statement)

extension=php_openssl.dll

The for-in statement is really there to enumerate over object properties, which is how it is implemented in TypeScript. There are some issues with using it on arrays.

I can't speak on behalf of the TypeScript team, but I believe this is the reason for the implementation in the language.

Use this code:

<!DOCTYPE html>
<html>
<head>
<style>
.text-center{
    text-align:center;
    margin-left:auto;
    margin-right:auto;
}
</style>
</head>
<body>

<div class="text-center">
<canvas id="myCanvas" width="200" height="100" style="border:1px solid #000000;">
Your browser does not support the HTML5 canvas tag.
</canvas>
</div>

</body>
</html>

One useful example that I came across may be helpful:

from itertools import groupby

#user input

myinput = input()

#creating empty list to store output

myoutput = []

for k,g in groupby(myinput):

    myoutput.append((len(list(g)),int(k)))

print(*myoutput)

Sample input: 14445221

Sample output: (1,1) (3,4) (1,5) (2,2) (1,1)

My full example is here, but I will provide a summary below.

Layout

Add a .swift and .xib file each with the same name to your project. The .xib file contains your custom view layout (using auto layout constraints preferably).

Make the swift file the xib file's owner.

Code

Add the following code to the .swift file and hook up the outlets and actions from the .xib file.

import UIKit
class ResuableCustomView: UIView {

    let nibName = "ReusableCustomView"
    var contentView: UIView?

    @IBOutlet weak var label: UILabel!
    @IBAction func buttonTap(_ sender: UIButton) {
        label.text = "Hi"
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)

        guard let view = loadViewFromNib() else { return }
        view.frame = self.bounds
        self.addSubview(view)
        contentView = view
    }

    func loadViewFromNib() -> UIView? {
        let bundle = Bundle(for: type(of: self))
        let nib = UINib(nibName: nibName, bundle: bundle)
        return nib.instantiate(withOwner: self, options: nil).first as? UIView
    }
}

Use it

Use your custom view anywhere in your storyboard. Just add a UIView and set the class name to your custom class name.

For a while Christopher Swasey's approach was the best approach I had found. I asked a couple of the senior devs on my team about it and one of them had the perfect solution! It satisfies every one of the concerns that Christopher Swasey so eloquently addressed and it doesn't require boilerplate subclass code(my main concern with his approach). There is one gotcha, but other than that it is fairly intuitive and easy to implement.

1. Create a custom UIView class in a .swift file to control your xib. i.e. MyCustomClass.swift
2. Create a .xib file and style it as you want. i.e. MyCustomClass.xib
3. Set the File's Owner of the .xib file to be your custom class (MyCustomClass)
4. GOTCHA: leave the class value (under the identity Inspector) for your custom view in the .xib file blank. So your custom view will have no specified class, but it will have a specified File's Owner.
5. Hook up your outlets as you normally would using the Assistant Editor.
   • NOTE: If you look at the Connections Inspector you will notice that your Referencing Outlets do not reference your custom class (i.e. MyCustomClass), but rather reference File's Owner. Since File's Owner is specified to be your custom class, the outlets will hook up and work propery.
6. Make sure your custom class has @IBDesignable before the class statement.
7. Make your custom class conform to the NibLoadable protocol referenced below.
   • NOTE: If your custom class .swift file name is different from your .xib file name, then set the nibName property to be the name of your .xib file.
8. Implement required init?(coder aDecoder: NSCoder) and override init(frame: CGRect) to call setupFromNib() like the example below.
9. Add a UIView to your desired storyboard and set the class to be your custom class name (i.e. MyCustomClass).
10. Watch IBDesignable in action as it draws your .xib in the storyboard with all of it's awe and wonder.

Here is the protocol you will want to reference:

public protocol NibLoadable {
    static var nibName: String { get }
}

public extension NibLoadable where Self: UIView {

    public static var nibName: String {
        return String(describing: Self.self) // defaults to the name of the class implementing this protocol.
    }

    public static var nib: UINib {
        let bundle = Bundle(for: Self.self)
        return UINib(nibName: Self.nibName, bundle: bundle)
    }

    func setupFromNib() {
        guard let view = Self.nib.instantiate(withOwner: self, options: nil).first as? UIView else { fatalError("Error loading \(self) from nib") }
        addSubview(view)
        view.translatesAutoresizingMaskIntoConstraints = false
        view.leadingAnchor.constraint(equalTo: self.safeAreaLayoutGuide.leadingAnchor, constant: 0).isActive = true
        view.topAnchor.constraint(equalTo: self.safeAreaLayoutGuide.topAnchor, constant: 0).isActive = true
        view.trailingAnchor.constraint(equalTo: self.safeAreaLayoutGuide.trailingAnchor, constant: 0).isActive = true
        view.bottomAnchor.constraint(equalTo: self.safeAreaLayoutGuide.bottomAnchor, constant: 0).isActive = true
    }
}

And here is an example of MyCustomClass that implements the protocol (with the .xib file being named MyCustomClass.xib):

@IBDesignable
class MyCustomClass: UIView, NibLoadable {

    @IBOutlet weak var myLabel: UILabel!

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        setupFromNib()
    }

    override init(frame: CGRect) {
        super.init(frame: frame)
        setupFromNib()
    }

}

NOTE: If you miss the Gotcha and set the class value inside your .xib file to be your custom class, then it will not draw in the storyboard and you will get a EXC_BAD_ACCESS error when you run the app because it gets stuck in an infinite loop of trying to initialize the class from the nib using the init?(coder aDecoder: NSCoder) method which then calls Self.nib.instantiate and calls the init again.

To change working directory in GitMSYS's Git Bash you can just use cd

cd /path/do/directory

Note that:

• Directory separators use the forward-slash (/) instead of backslash.
• Drives are specified with a lower case letter and no colon, e.g. "C:\stuff" should be represented with "/c/stuff".
• Spaces can be escaped with a backslash (\)
• Command line completion is your friend. Press TAB at anytime to expand stuff, including Git options, branches, tags, and directories.

Also, you can right click in Windows Explorer on a directory and "Git Bash here".

do you try

[{"name":"myEnterprise", "departments":["HR"]}]

the square brace is the key point.

If you are in same network then add the destination server to the MS Server management studio using connect option and then try exporting from source to destination. The most easiest way :)

I solve the problem my issue was I had file named queue.py in the same directory

An alternate way is to construct a view which is then queried just like a table. In many database managers using a view can result in better performance.

CREATE VIEW xyz SELECT q.question, a.alternative  
   FROM tbl_question AS q, tbl_alternative AS a
  WHERE q.categoryid = a.categoryid 
    AND q._id = a.questionid;

This is from memory so there may be some syntactic issues. http://www.sqlite.org/lang_createview.html

I mention this approach because then you can use SQLiteQueryBuilder with the view as you implied that it was preferred.

I feel your pain ... yet another date time format... just what you needed!

Using Web Api 2 you can use route attributes to specify parameters.

so with attributes on your class and your method you can code up a REST URL using this utc format you are having trouble with (apparently its ISO8601, presumably arrived at using startDate.toISOString())

[Route(@"daterange/{startDate:regex(^\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2}.\d{3}Z$)}/{endDate:regex(^\d{4}-\d{2}-\d{2}T\d{2}:\d{2}:\d{2}.\d{3}Z$)}")]
    [HttpGet]
    public IEnumerable<MyRecordType> GetByDateRange(DateTime startDate, DateTime endDate)

.... BUT, although this works with one date (startDate), for some reason it doesnt work when the endDate is in this format ... debugged for hours, only clue is exception says it doesnt like colon ":" (even though web.config is set with :

<system.web>
    <compilation debug="true" targetFramework="4.5.1" />
    <httpRuntime targetFramework="4.5.1" requestPathInvalidCharacters="" />
</system.web>

So, lets make another date format (taken from the polyfill for the ISO date format) and add it to the Javascript date (for brevity, only convert up to minutes):

if (!Date.prototype.toUTCDateTimeDigits) {
    (function () {

        function pad(number) {
            if (number < 10) {
                return '0' + number;
            }
            return number;
        }

        Date.prototype.toUTCDateTimeDigits = function () {
            return this.getUTCFullYear() +
              pad(this.getUTCMonth() + 1) +
              pad(this.getUTCDate()) +
              'T' +
              pad(this.getUTCHours()) +
              pad(this.getUTCMinutes()) +
              'Z';
        };

    }());
}

Then when you send the dates to the Web API 2 method, you can convert them from string to date:

[RoutePrefix("api/myrecordtype")]
public class MyRecordTypeController : ApiController
{


    [Route(@"daterange/{startDateString}/{endDateString}")]
    [HttpGet]
    public IEnumerable<MyRecordType> GetByDateRange([FromUri]string startDateString, [FromUri]string endDateString)
    {
        var startDate = BuildDateTimeFromYAFormat(startDateString);
        var endDate = BuildDateTimeFromYAFormat(endDateString);
    ...
    }

    /// <summary>
    /// Convert a UTC Date String of format yyyyMMddThhmmZ into a Local Date
    /// </summary>
    /// <param name="dateString"></param>
    /// <returns></returns>
    private DateTime BuildDateTimeFromYAFormat(string dateString)
    {
        Regex r = new Regex(@"^\d{4}\d{2}\d{2}T\d{2}\d{2}Z$");
        if (!r.IsMatch(dateString))
        {
            throw new FormatException(
                string.Format("{0} is not the correct format. Should be yyyyMMddThhmmZ", dateString)); 
        }

        DateTime dt = DateTime.ParseExact(dateString, "yyyyMMddThhmmZ", CultureInfo.InvariantCulture, DateTimeStyles.AssumeUniversal);

        return dt;
    }

so the url would be

http://domain/api/myrecordtype/daterange/20140302T0003Z/20140302T1603Z

Hanselman gives some related info here:

#include "header.h"

int estimatedPopulation (int currentPopulation, float growthRate)
{
    return currentPopulation + currentPopulation * growthRate  / 100;
}

I would also mention that using IOC aka Unity may make these assessments misleading. I may have erred but several very important classes that are instantiated via Unity appear to have no instantiation as far as ReSharper can tell. If I followed the ReSharper recommendations I would get hosed!

If you need unary numeral system, you can convert an integer like this:

>> n = 6
>> '1' * n
'111111'

If you need a support of negative ints you can just write like that:

>> n = -6
>> '1' * n if n >= 0 else '-' + '1' * (-n)
'-111111'

Zero is special case which takes an empty string in this case, which is correct.

>> n = 0
>> '1' * n if n >= 0 else '-' + '1' * (-n)
''

Jay Gilford's answer will work, but I think really the easiest way is to just slap a display: none; on a submit button in the form.

If you are using java 8 the use of the internal Base64 encoder and decoder can be avoided by replacing

return new BASE64Encoder().encode(bytes);

with

return Base64.getEncoder().encodeToString(bytes);

and

return new BASE64Decoder().decodeBuffer(property);

with

return Base64.getDecoder().decode(property);

Note that this solution doesn't protect your data as the methods for decrypting are stored in the same place. It just makes it more difficult to break. Mainly it avoids to print it and show it to everybody by mistake.

List<String> sids = new ArrayList<String>();
List<String> lids = new ArrayList<String>();

String query = "SELECT rlink_id, COUNT(*)"
             + "FROM dbo.Locate  "
             + "GROUP BY rlink_id ";

Statement stmt = yourconnection.createStatement();
try {
    ResultSet rs4 = stmt.executeQuery(query);

    while (rs4.next()) {
        sids.add(rs4.getString(1));
        lids.add(rs4.getString(2));
    }
} finally {
    stmt.close();
}

String show[] = sids.toArray(sids.size());
String actuate[] = lids.toArray(lids.size());

This question was posted quite a while ago and most of the answers are quite old too. So when I spent hours trying to figure this out, nothing worked, and I tried all suggestions in this post.

I was still getting the standard JPEG errors when trying to upload a JPG in my Django avatar form:

raise IOError("decoder %s not available" % decoder_name)
OSError: decoder jpeg not available

Then I checked the repository for Ubuntu 12.04 and noticed some extra packages for libjpeg. I installed these and my problem was solved:

sudo apt-get install libjpeg62 libjpeg62-dev

Installing these removed libjpeg-dev, libjpeg-turbo8-dev, and libjpeg8-dev.

Hope this helps someone in the year 2015 and beyond!

Another option would be to use a procedure with output parameters - Using a Stored Procedure with Output Parameters

Matplotlib uses a dictionary from its colors.py module.

To print the names use:

# python2:

import matplotlib
for name, hex in matplotlib.colors.cnames.iteritems():
    print(name, hex)

# python3:

import matplotlib
for name, hex in matplotlib.colors.cnames.items():
    print(name, hex)

This is the complete dictionary:

You could plot them like this:

import matplotlib.pyplot as plt
import matplotlib.patches as patches
import matplotlib.colors as colors
import math


fig = plt.figure()
ax = fig.add_subplot(111)

ratio = 1.0 / 3.0
count = math.ceil(math.sqrt(len(colors.cnames)))
x_count = count * ratio
y_count = count / ratio
x = 0
y = 0
w = 1 / x_count
h = 1 / y_count

for c in colors.cnames:
    pos = (x / x_count, y / y_count)
    ax.add_patch(patches.Rectangle(pos, w, h, color=c))
    ax.annotate(c, xy=pos)
    if y >= y_count-1:
        x += 1
        y = 0
    else:
        y += 1

plt.show()

Had the exact same issue. I installed curl 7.19 to /opt/curl/ to make sure that I would not affect current curl on our production servers. Once I linked libcurl.so.4 to /usr/lib:

sudo ln -s /opt/curl/lib/libcurl.so /usr/lib/libcurl.so.4

I still got the same error! Durf.

But running ldconfig make the linkage for me and that worked. No need to set the LD_RUN_PATH or LD_LIBRARY_PATH at all. Just needed to run ldconfig.

Just wrap your option in $(option) to make it act the way you want it to. You can also make the code shorter by doing

$('#span_id > select > option[value="input your i here"]').attr("selected", "selected")

try tomcat tomcat as the default username and password (tomcat 7)

Try this code refer from here

Assuming array equality means both arrays have equal elements at equal indexes, there is the SequenceEqual answer and the IStructuralEquatable answer.

But both have drawbacks, performance wise.

SequenceEqual current implementation will not shortcut when the arrays have different lengths, and so it may enumerate one of them entirely, comparing each of its elements.

IStructuralEquatable is not generic and may cause boxing of each compared value. Moreover it is not very straightforward to use and already calls for coding some helper methods hiding it away.

It may be better, performance wise, to use something like:

bool ArrayEquals<T>(T[] first, T[] second)
{
    if (first == second)
        return true;
    if (first == null || second == null)
        return false;
    if (first.Length != second.Length)
        return false;
    for (var i = 0; i < first.Length; i++)
    {
        if (!first[i].Equals(second[i]))
            return false;
    }
    return true;
}

But of course, that is not either some "magic way" of checking array equality.

So currently, no, there is not really an equivalent to Java Arrays.equals() in .Net.

Open Console/Command line --> Go to your Jenkins installation directory. Execute the following commands respectively:

to stop:
jenkins.exe stop

to start:
jenkins.exe start

to restart:
jenkins.exe restart

I found a solution to implement this with the help of the Apple Developer Forums:

• Specify location background mode
• Create an NSTimer in the background with UIApplication:beginBackgroundTaskWithExpirationHandler:
• When n is smaller than UIApplication:backgroundTimeRemaining it will work just fine. When n is larger, the location manager should be enabled (and disabled) again before there is no time remaining to avoid the background task being killed.

This works because location is one of the three allowed types of background execution.

Note: I lost some time by testing this in the simulator where it doesn't work. However, it works fine on my phone.

In my case I have used context for startActivity, after changing that with ActivityName.this . it solves. I'm using method from util class so this happens.

Hope it help some one.

In Pythons <= 3.4 you can, as others suggested, use list(range(10)) in order to make a list out of a range (In general, any iterable).

Another alternative, introduced in Python 3.5 with its unpacking generalizations, is by using * in a list literal []:

>>> r = range(10)
>>> l = [*r]
>>> print(l)
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

Though this is equivalent to list(r), it's literal syntax and the fact that no function call is involved does let it execute faster. It's also less characters, if you need to code golf :-)

The concatenation operator '&' is allowed on the right side of the signal assignment operator '<=', only

I had some problems with the other solutions on this page, so thought I'd drop this in.

@Html.TextBoxFor(m => m.EndDate, "{0:d}", new { @class = "form-control datepicker" })

So you only need to add "{0:d}" in the second parameter and you should be good to go.

You can do as follows

1.Remove href attribute from anchor(a) tag

2.Set pointer cursor in css to ng click elements

 [ng-click],
 [data-ng-click],
 [x-ng-click] {
     cursor: pointer;
 }

In my case I had this error, /var/run/postgresql/.s.PGSQL.5433 (note, one number up from the file it was looking for, .s.PGSQL.5432) was present. Tried the instructions at the top of this page but nothing worked.

Turns out there was an old directory for PostGreSQL 12 config files in /etc/postgresql/12, which I deleted, which solved the issue.

One suggestion I'll make since no one yet has said it: PLEASE PLEASE PLEASE make a backup of your whole .xcodeproj file BEFORE you start modifying it's contents. Screwing up the project file and having no backup will lead to a very very unpleasant experience.

Being able to back out of an edit can be a godsend.

It has to do with the way the post-increment operator works. It returns the value of i and then increments the value.

Obj-C way =):

NSString *inStr = [@(month) stringValue];

After just suffering the same issue I found my resolution was to delete all pyc files from my project, it seems like these cached files were somehow causing this error.

Easiest way I found to do this was to navigate to my project folder in Windows explorer and searching for *.pyc, then selecting all (Ctrl+A) and deleting them (Ctrl+X).

Its possible I could have resolved my issues by just deleting the specific pyc file but I never tried this

GitStack should meet your goal. I has a wizard setup. It is free for 2 users and has a web based user interface. It is based on msysgit.

Try this:

runas.exe /savecred /user:administrator "%sysdrive%\testScripts\testscript1.ps1" 

It saves the password the first time and never asks again. Maybe when you change the administrator password you will be prompted again.

Add this to the stylesheet:

table {
  border-collapse: collapse;
}

JSFiddle.

The reason why it behaves this way is actually described pretty well in the specification:

There are two distinct models for setting borders on table cells in CSS. One is most suitable for so-called separated borders around individual cells, the other is suitable for borders that are continuous from one end of the table to the other.

... and later, for collapse setting:

In the collapsing border model, it is possible to specify borders that surround all or part of a cell, row, row group, column, and column group.

Newer versions of the DOMTokenList spec allow for multiple arguments to add() and remove(), as well as a second argument to toggle() to force state.

At the time of writing, Chrome supports multiple arguments to add() and remove(), but none of the other browsers do. IE 10 and lower, Firefox 23 and lower, Chrome 23 and lower and other browsers do not support the second argument to toggle().

I wrote the following small polyfill to tide me over until support expands:

(function () {
    /*global DOMTokenList */
    var dummy  = document.createElement('div'),
        dtp    = DOMTokenList.prototype,
        toggle = dtp.toggle,
        add    = dtp.add,
        rem    = dtp.remove;

    dummy.classList.add('class1', 'class2');

    // Older versions of the HTMLElement.classList spec didn't allow multiple
    // arguments, easy to test for
    if (!dummy.classList.contains('class2')) {
        dtp.add    = function () {
            Array.prototype.forEach.call(arguments, add.bind(this));
        };
        dtp.remove = function () {
            Array.prototype.forEach.call(arguments, rem.bind(this));
        };
    }

    // Older versions of the spec didn't have a forcedState argument for
    // `toggle` either, test by checking the return value after forcing
    if (!dummy.classList.toggle('class1', true)) {
        dtp.toggle = function (cls, forcedState) {
            if (forcedState === undefined)
                return toggle.call(this, cls);

            (forcedState ? add : rem).call(this, cls);
            return !!forcedState;
        };
    }
})();

A modern browser with ES5 compliance and DOMTokenList are expected, but I'm using this polyfill in several specifically targeted environments, so it works great for me, but it might need tweaking for scripts that will run in legacy browser environments such as IE 8 and lower.

By the looks of it you need to actually pass drawImage an image object like so

var canvas = document.getElementById("c");_x000D_
var ctx = canvas.getContext("2d");_x000D_
_x000D_
var image = new Image();_x000D_

I've tried it in chrome and it works fine.

There is also now https://github.com/xk/node-threads-a-gogo, though I'm not sure about project status.

Like the answer above but here is using bootstrap 3 names and colours:

/*css to add back colours for badges and make use of the colours*/_x000D_
.badge-default {_x000D_
  background-color: #999999;_x000D_
}_x000D_
_x000D_
.badge-primary {_x000D_
  background-color: #428bca;_x000D_
}_x000D_
_x000D_
.badge-success {_x000D_
  background-color: #5cb85c;_x000D_
}_x000D_
_x000D_
.badge-info {_x000D_
  background-color: #5bc0de;_x000D_
}_x000D_
_x000D_
.badge-warning {_x000D_
  background-color: #f0ad4e;_x000D_
}_x000D_
_x000D_
.badge-danger {_x000D_
  background-color: #d9534f;_x000D_
}

Surprised nobody has mentioned the most obvious solution, use the std::vector constructor.

template<typename K, typename V>
std::vector<std::pair<K,V>> mapToVector(const std::unordered_map<K,V> &map)
{
    return std::vector<std::pair<K,V>>(map.begin(), map.end());
}

I had some lint errors in Android Studio that occurred only when I generated a signed APK.

To avoid it, I added the following to build.gradle

android {
    lintOptions {
        checkReleaseBuilds false
    }
}

All notifications (even other app notifications) can be removed via listening to 'NotificationListenerService' as mentioned in NotificationListenerService Implementation

In the service you have to call cancelAllNotifications().

The service has to be enabled for your application via:

‘Apps & notifications’ -> ‘Special app access’ -> ‘Notifications access’.

First create a Project With PdfCreation in Android Studio

Then Follow below steps:

1.Download itextpdf-5.3.2.jar library from this link [https://sourceforge.net/projects/itext/files/iText/iText5.3.2/][1] and then
2.Add to app>libs>itextpdf-5.3.2.jar
3.Right click on jar file then click on add to library
4. Document document = new Document(PageSize.A4); // Create Directory in External Storage
        String root = Environment.getExternalStorageDirectory().toString();

Others have taken the approach to say "don't do this" but that doesn't really answer the poster's question. Let's just assume that everyone knows this is a bad idea, but we are curious about how it's done anyway...

You cannot disable the back button on a user's browser, but you can make it so that your application breaks (displays an error message, requiring the user to start over) if the user goes back.

One approach I have seen for doing this is to pass a token on every URL within the application, and within every form. The token is regenerated on every page, and once the user loads a new page any tokens from previous pages are invalidated.

When the user loads a page, the page will only show if the correct token (which was given to all links/forms on the previous page) was passed to it.

The online banking application my bank provides is like this. If you use the back button at all, no more links will work and no more page reloads can be made - instead you see a notice telling you that you cannot go back, and you have to start over.

I had this problem with my Ubuntu.

All I needed to do to get sources for my java insallation was:

sudo apt-get install sun-java6-source 

Another system (not mentioned in the accepted answer yet) is PyInstaller, which worked for a PyQt project of mine when py2exe would not. I found it easier to use.

http://www.pyinstaller.org/

Pyinstaller is based on Gordon McMillan's Python Installer. Which is no longer available.

Here's a similar command I know works:

curl -v -H "Content-Type: application/json" -H "Authorization: Basic cGC3COJ1c2Vy925hZGFJbXBvcnABCnRl" -X PUT -d '{"mappings":{"properties":{"city":{"type": "text"}}}}' https://35.80.2.21/manzanaIndex

The breakdown for the above curl command is:

PUT /manzanaIndex
{
    "mappings":{
        "properties":{
                "city":{
                    "type": "text"
                }
        }
    }
}

Ultimately you always have a finite max of heap to use no matter what platform you are running on. In Windows 32 bit this is around 2GB (not specifically heap but total amount of memory per process). It just happens that Java chooses to make the default smaller (presumably so that the programmer can't create programs that have runaway memory allocation without running into this problem and having to examine exactly what they are doing).

So this given there are several approaches you could take to either determine what amount of memory you need or to reduce the amount of memory you are using. One common mistake with garbage collected languages such as Java or C# is to keep around references to objects that you no longer are using, or allocating many objects when you could reuse them instead. As long as objects have a reference to them they will continue to use heap space as the garbage collector will not delete them.

In this case you can use a Java memory profiler to determine what methods in your program are allocating large number of objects and then determine if there is a way to make sure they are no longer referenced, or to not allocate them in the first place. One option which I have used in the past is "JMP" http://www.khelekore.org/jmp/.

If you determine that you are allocating these objects for a reason and you need to keep around references (depending on what you are doing this might be the case), you will just need to increase the max heap size when you start the program. However, once you do the memory profiling and understand how your objects are getting allocated you should have a better idea about how much memory you need.

In general if you can't guarantee that your program will run in some finite amount of memory (perhaps depending on input size) you will always run into this problem. Only after exhausting all of this will you need to look into caching objects out to disk etc. At this point you should have a very good reason to say "I need Xgb of memory" for something and you can't work around it by improving your algorithms or memory allocation patterns. Generally this will only usually be the case for algorithms operating on large datasets (like a database or some scientific analysis program) and then techniques like caching and memory mapped IO become useful.

Yes. The VBA equivalent of AltEnter is to use a linebreak character:

ActiveCell.Value = "I am a " & Chr(10) & "test"

Note that this automatically sets WrapText to True.

Proof:

Sub test()
Dim c As Range
Set c = ActiveCell
c.WrapText = False
MsgBox "Activcell WrapText is " & c.WrapText
c.Value = "I am a " & Chr(10) & "test"
MsgBox "Activcell WrapText is " & c.WrapText
End Sub

I made a base class for widget state

Usage instead of State<LoginPage> use BaseState<LoginPage> then just use the boolean variable isOnline

Text(isOnline ? 'is Online' : 'is Offline')

First, add connectivity plugin:

dependencies:
  connectivity: ^0.4.3+2

Then add the BaseState class

import 'dart:async';
import 'dart:io';
import 'package:flutter/services.dart';

import 'package:connectivity/connectivity.dart';
import 'package:flutter/widgets.dart';

/// a base class for any statful widget for checking internet connectivity
abstract class BaseState<T extends StatefulWidget> extends State {

  void castStatefulWidget();

  final Connectivity _connectivity = Connectivity();

  StreamSubscription<ConnectivityResult> _connectivitySubscription;

  /// the internet connectivity status
  bool isOnline = true;

  /// initialize connectivity checking
  /// Platform messages are asynchronous, so we initialize in an async method.
  Future<void> initConnectivity() async {
    // Platform messages may fail, so we use a try/catch PlatformException.
    try {
      await _connectivity.checkConnectivity();
    } on PlatformException catch (e) {
      print(e.toString());
    }

    // If the widget was removed from the tree while the asynchronous platform
    // message was in flight, we want to discard the reply rather than calling
    // setState to update our non-existent appearance.
    if (!mounted) {
      return;
    }

    await _updateConnectionStatus().then((bool isConnected) => setState(() {
          isOnline = isConnected;
        }));
  }

  @override
  void initState() {
    super.initState();
    initConnectivity();
    _connectivitySubscription = Connectivity()
        .onConnectivityChanged
        .listen((ConnectivityResult result) async {
      await _updateConnectionStatus().then((bool isConnected) => setState(() {
            isOnline = isConnected;
          }));
    });
  }

  @override
  void dispose() {
    _connectivitySubscription.cancel();
    super.dispose();
  }

  Future<bool> _updateConnectionStatus() async {
    bool isConnected;
    try {
      final List<InternetAddress> result =
          await InternetAddress.lookup('google.com');
      if (result.isNotEmpty && result[0].rawAddress.isNotEmpty) {
        isConnected = true;
      }
    } on SocketException catch (_) {
      isConnected = false;
      return false;
    }
    return isConnected;
  }
}

And you need to cast the widget in your state like this

@override
  void castStatefulWidget() {
    // ignore: unnecessary_statements
    widget is StudentBoardingPage;
  }

Pojo also consider as Model class in Java where we can create getter and setter for particular variable defined in private . Remember all variables are here declared with private modifier

You can check out this method for sending image and form data altogether

<div class="form-group ml-5 mt-4" ng-app="myApp" ng-controller="myCtrl">
                    <label for="image_name">Image Name:</label>
                    <input type="text"   placeholder="Image name" ng-model="fileName" class="form-control" required>
                    <br>

                    <br>
                    <input id="file_src" type="file"   accept="image/jpeg" file-input="files"   >
                    <br>
                        {{file_name}}
            <img class="rounded mt-2 mb-2 " id="prvw_img" width="150" height="100" >
                    <hr>
                      <button class="btn btn-info" ng-click="uploadFile()">Upload</button>
                        <br>

                       <div ng-show = "IsVisible" class="alert alert-info w-100 shadow mt-2" role="alert">
              <strong> {{response_msg}} </strong>
            </div>
                            <div class="alert alert-danger " id="filealert"> <strong> File Size should be less than 4 MB </strong></div>
                    </div>

Angular JS Code

    var app = angular.module("myApp", []);
 app.directive("fileInput", function($parse){
      return{
           link: function($scope, element, attrs){
                element.on("change", function(event){
                     var files = event.target.files;

                });
           }
      }
 });
 app.controller("myCtrl", function($scope, $http){
      $scope.IsVisible = false;
      $scope.uploadFile = function(){
           var form_data = new FormData();
           angular.forEach($scope.files, function(file){
                form_data.append('file', file); //form file
                                form_data.append('file_Name',$scope.fileName); //form text data
           });
           $http.post('upload.php', form_data,
           {
                //'file_Name':$scope.file_name;
                transformRequest: angular.identity,
                headers: {'Content-Type': undefined,'Process-Data': false}
           }).success(function(response){
             $scope.IsVisible = $scope.IsVisible = true;
                      $scope.response_msg=response;
               // alert(response);
               // $scope.select();
           });
      }

 });

Really it comes down to what you want the query to do. If you mean an exact match then use =. If you mean a fuzzier match, then use LIKE. Saying what you mean is usually a good policy with code.

You are using USCOUNTER in a subshell, that's why the variable is not showing in the main shell.

Instead of cat FILE | while ..., do just a while ... done < $FILE. This way, you avoid the common problem of I set variables in a loop that's in a pipeline. Why do they disappear after the loop terminates? Or, why can't I pipe data to read?:

while read country _; do
  if [ "US" = "$country" ]; then
        USCOUNTER=$(expr $USCOUNTER + 1)
        echo "US counter $USCOUNTER"
  fi
done < "$FILE"

Note I also replaced the `` expression with a $().

I also replaced while read line; do country=$(echo "$line" | cut -d' ' -f1) with while read country _. This allows you to say while read var1 var2 ... varN where var1 contains the first word in the line, $var2 and so on, until $varN containing the remaining content.

This warning comes because your dataframe x is a copy of a slice. This is not easy to know why, but it has something to do with how you have come to the current state of it.

You can either create a proper dataframe out of x by doing

x = x.copy()

This will remove the warning, but it is not the proper way

You should be using the DataFrame.loc method, as the warning suggests, like this:

x.loc[:,'Mass32s'] = pandas.rolling_mean(x.Mass32, 5).shift(-2)

postgresql_autodoc is a cli for doing this. Doesnt do cardinality, but none of the above mentioned GUI tools do as well.

The original code works fine for reading and separating the csv file data but you need to change the data type from csv to text.

Look on my solution. I suppose that you should set selected position in holder and pass it as Tag of View. The view should be set in the onCreateViewHolder(...) method. There is also correct place to set listener for view such as OnClickListener or LongClickListener.

Please look on the example below and read comments to code.

public class MyListAdapter extends RecyclerView.Adapter<MyListAdapter.ViewHolder> {
    //Here is current selection position
    private int mSelectedPosition = 0;
    private OnMyListItemClick mOnMainMenuClickListener = OnMyListItemClick.NULL;

    ...

    // constructor, method which allow to set list yourObjectList

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        //here you prepare your view 
        // inflate it
        // set listener for it
        final ViewHolder result = new ViewHolder(view);
        final View view =  LayoutInflater.from(parent.getContext()).inflate(R.layout.your_view_layout, parent, false);
        view.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                //here you set your current position from holder of clicked view
                mSelectedPosition = result.getAdapterPosition();

                //here you pass object from your list - item value which you clicked
                mOnMainMenuClickListener.onMyListItemClick(yourObjectList.get(mSelectedPosition));

                //here you inform view that something was change - view will be invalidated
                notifyDataSetChanged();
            }
        });
        return result;
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        final YourObject yourObject = yourObjectList.get(position);

        holder.bind(yourObject);
        if(mSelectedPosition == position)
            holder.itemView.setBackgroundColor(Color.CYAN);
        else
            holder.itemView.setBackgroundColor(Color.RED);
    }

    // you can create your own listener which you set for adapter
    public void setOnMainMenuClickListener(OnMyListItemClick onMyListItemClick) {

Angular expressions do not support the ternary operator before 1.1.5, but it can be emulated like this:

condition && (answer if true) || (answer if false)

So in example, something like this would work:

<div ng-repeater="item in items">
    <div>{{item.description}}</div>
    <div>{{isExists(item) && 'available' || 'oh no, you don't have it'}}</div>
</div>

UPDATE: Angular 1.1.5 added support for ternary operators:

{{myVar === "two" ? "it's true" : "it's false"}}

using html5 data attribute...

try this

$(function(){
$('input:button').click(function () {
  $('#count').val($(this).data('quantity') * $('#product_price').text());

How about an extension method that doesn't use regex.

If you do stick to one of the Regex options at least use RegexOptions.Compiled in the static variable.

public static string ToDigitsOnly(this string input)
{
    return new String(input.Where(char.IsDigit).ToArray());
}

This builds on Usman Zafar's answer converted to a method group.

You could create a simple batch script to do this for you:

TYPE %1 | MORE /P >%1.1
MOVE %1.1 %1

Then run <batch script name> <FILE> and <FILE> will be instantly converted to DOS line endings.

You need to link with the math library:

gcc -o sphere sphere.c -lm

The error you are seeing: error: ld returned 1 exit status is from the linker ld (part of gcc that combines the object files) because it is unable to find where the function pow is defined.

Including math.h brings in the declaration of the various functions and not their definition. The def is present in the math library libm.a. You need to link your program with this library so that the calls to functions like pow() are resolved.

I came across this old question in my search for an answer, and I thought I would just post the solution I found in case someone else passes by here looking for the same.

For swapping 2 elements, Collections.swap is fine. But if we want to move more elements, there is a better solution that involves a creative use of Collections.sublist and Collections.rotate that I hadn't thought of until I saw it described here:

http://docs.oracle.com/javase/6/docs/api/java/util/Collections.html#rotate%28java.util.List,%20int%29

Here's a quote, but go there and read the whole thing for yourself too:

Note that this method can usefully be applied to sublists to move one or more elements within a list while preserving the order of the remaining elements. For example, the following idiom moves the element at index j forward to position k (which must be greater than or equal to j):

Collections.rotate(list.subList(j, k+1), -1);

Here Value 1 to 10 are column names that you are getting

I would use the translate method without translation table. It deletes the letters in second argument in recent Python versions.

def remove_chars(line):
    line7=line[7].translate(None,'abcd')
    return line[:7]+[line7]+line[8:]

line= ['ad','da','sdf','asd',
        '3424','342sfas','asdfaf','sdfa',
        'afase']
print line[7]
line = remove_chars(line)
print line[7]

The example provided by @tster shows how to create a list of list. I will provide an example for iterating over such a list.

Iterator<List<String>> iter = listOlist.iterator();
while(iter.hasNext()){
    Iterator<String> siter = iter.next().iterator();
    while(siter.hasNext()){
         String s = siter.next();
         System.out.println(s);
     }
}

I'll assume you need it for one-off things. I'll assume you're a PC developer.

Use the Stack, Luke. Use it everywhere. Don't use malloc / free for small allocations, ever.

#include <string.h>
#include <stdio.h>

#define STR_SIZE 10000

int main()
{
  char s1[] = "oppa";
  char s2[] = "gangnam";
  char s3[] = "style";

  {
    char result[STR_SIZE] = {0};
    snprintf(result, sizeof(result), "%s %s %s", s1, s2, s3);
    printf("%s\n", result);
  }
}

If 10 KB per string won't be enough, add a zero to the size and don't bother, - they'll release their stack memory at the end of the scopes anyway.

With my current reputation I have no ability to comment, so I choose answer referencing comments for sample code in reply by Prashant Gaur (thanks, Gaur - this was helpful!) - his sample is for python2, since python3 has no

unicode

The replacement below for function

get_prep_value(self, value):

encoding='utf-8', errors='ignore'

decode()

unicode() methods

errors='ignore'

import sys

...

    def get_prep_value(self, value):
        if value is None:
            return value
        if sys.version_info[0] >= 3:
            if isinstance(out_data, type(b'')):
                return value.decode(encoding='utf-8', errors='ignore')
        else:
            if isinstance(out_data, type(b'')):
                return unicode(value, encoding='utf-8', errors='ignore')
        return str(value)

Here is another good article that you may check out on Domain Driven Design. if your application is anything serious than college assignment. The basic premise is structure everything around your entities and have a strong domain model. Differentiate between services that provide infrastructure related things (like sending email, persisting data) and services that actually do things that are your core business requirments.

Hope that helps.

Unfortunately they are all out of date. DBCP has been updated a bit recently, the other two are 2-3 years old, with many outstanding bugs.

First add your item to mItems and then use:

mAdapter.notifyItemInserted(mItems.size() - 1);

this method is better than using:

mAdapter.notifyDataSetChanged();

in performance.

In Java 8, for anyone looking now to read file large files line by line,

Stream<String> lines = Files.lines(Paths.get("c:\myfile.txt"));
lines.forEach(l -> {
  // Do anything line by line   
});

Here is the consolidated list order by my preference.

Using apache commons

import org.apache.commons.io.FilenameUtils;

String fileNameWithoutExt = FilenameUtils.getBaseName(fileName);
                          
                           OR

String fileNameWithOutExt = FilenameUtils.removeExtension(fileName);

Using Google Guava (If u already using it)

import com.google.common.io.Files;
String fileNameWithOutExt = Files.getNameWithoutExtension(fileName);

Files.getNameWithoutExtension

Or using Core Java

1)

String fileName = file.getName();
int pos = fileName.lastIndexOf(".");
if (pos > 0 && pos < (fileName.length() - 1)) { // If '.' is not the first or last character.
    fileName = fileName.substring(0, pos);
}

if (fileName.indexOf(".") > 0) {
   return fileName.substring(0, fileName.lastIndexOf("."));
} else {
   return fileName;
}

private static final Pattern ext = Pattern.compile("(?<=.)\\.[^.]+$");

public static String getFileNameWithoutExtension(File file) {
    return ext.matcher(file.getName()).replaceAll("");
}

Liferay API

import com.liferay.portal.kernel.util.FileUtil; 
String fileName = FileUtil.stripExtension(file.getName());

For my style, I always use @ModelAttribute to catch object from spring form jsp. for example, I design form on jsp page, that form exist with commandName

<form:form commandName="Book" action="" methon="post">
      <form:input type="text" path="title"></form:input>
</form:form>

and I catch the object on controller with follow code

public String controllerPost(@ModelAttribute("Book") Book book)

and every field name of book must be match with path in sub-element of form

$("#select_id").find("option:selected").text();

It is helpful if your control is on Server side. In .NET it looks like:

$('#<%= dropdownID.ClientID %>').find("option:selected").text();

The first visible character is '!' according to ASCII table.And the last one is '~' So "!file.doc" or "~file.doc' will be the top one depending your ranking order. You can check the ascii table here: http://www.asciitable.com/
