If you want to avoid parsing the date and just want a timestamp in GMT, you could use:

final Date gmt = new Timestamp(System.currentTimeMillis()
            - Calendar.getInstance().getTimeZone()
                    .getOffset(System.currentTimeMillis()));

You are repeating the y,m,d.

Instead of

gmdate('yyyy-mm-dd hh:mm:ss \G\M\T', time());  

You should use it like

gmdate('Y-m-d h:m:s \G\M\T', time());

OP's solution to his problem, as he says, has dubious output. That code still shows confusion about representations of time. To clear up this confusion, and make code that won't lead to wrong times, consider this extension of what he did:

public static void _testDateFormatting() {
    SimpleDateFormat sdfGMT1 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");
    sdfGMT1.setTimeZone(TimeZone.getTimeZone("GMT"));
    SimpleDateFormat sdfGMT2 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss z");
    sdfGMT2.setTimeZone(TimeZone.getTimeZone("GMT"));

    SimpleDateFormat sdfLocal1 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");
    SimpleDateFormat sdfLocal2 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss z");

    try {
        Date d = new Date();
        String s1 = d.toString();
        String s2 = sdfLocal1.format(d);
        // Store s3 or s4 in database.
        String s3 = sdfGMT1.format(d);
        String s4 = sdfGMT2.format(d);
        // Retrieve s3 or s4 from database, using LOCAL sdf.
        String s5 = sdfLocal1.parse(s3).toString();
        //EXCEPTION String s6 = sdfLocal2.parse(s3).toString();
        String s7 = sdfLocal1.parse(s4).toString();
        String s8 = sdfLocal2.parse(s4).toString();
        // Retrieve s3 from database, using GMT sdf.
        // Note that this is the SAME sdf that created s3.
        Date d2 = sdfGMT1.parse(s3);
        String s9 = d2.toString();
        String s10 = sdfGMT1.format(d2);
        String s11 = sdfLocal2.format(d2);
    } catch (Exception e) {
        e.printStackTrace();
    }       
}

examining values in a debugger:

s1  "Mon Sep 07 06:11:53 EDT 2015" (id=831698113128)    
s2  "2015.09.07 06:11:53" (id=831698114048) 
s3  "2015.09.07 10:11:53" (id=831698114968) 
s4  "2015.09.07 10:11:53 GMT+00:00" (id=831698116112)   
s5  "Mon Sep 07 10:11:53 EDT 2015" (id=831698116944)    
s6  -- omitted, gave parse exception    
s7  "Mon Sep 07 10:11:53 EDT 2015" (id=831698118680)    
s8  "Mon Sep 07 06:11:53 EDT 2015" (id=831698119584)    
s9  "Mon Sep 07 06:11:53 EDT 2015" (id=831698120392)    
s10 "2015.09.07 10:11:53" (id=831698121312) 
s11 "2015.09.07 06:11:53 EDT" (id=831698122256) 

sdf2 and sdfLocal2 include time zone, so we can see what is really going on. s1 & s2 are at 06:11:53 in zone EDT. s3 & s4 are at 10:11:53 in zone GMT -- equivalent to the original EDT time. Imagine we save s3 or s4 in a data base, where we are using GMT for consistency, so we can have times from anywhere in the world, without storing different time zones.

s5 parses the GMT time, but treats it as a local time. So it says "10:11:53" -- the GMT time -- but thinks it is 10:11:53 in local time. Not good.

s7 parses the GMT time, but ignores the GMT in the string, so still treats it as a local time.

s8 works, because now we include GMT in the string, and the local zone parser uses it to convert from one time zone to another.

Now suppose you don't want to store the zone, you want to be able to parse s3, but display it as a local time. The answer is to parse using the same time zone it was stored in -- so use the same sdf as it was created in, sdfGMT1. s9, s10, & s11 are all representations of the original time. They are all "correct". That is, d2 == d1. Then it is only a question of how you want to DISPLAY it. If you want to display what is stored in DB -- GMT time -- then you need to format it using a GMT sdf. Ths is s10.

So here is the final solution, if you don't want to explicitly store with " GMT" in the string, and want to display in GMT format:

public static void _testDateFormatting() {
    SimpleDateFormat sdfGMT1 = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");
    sdfGMT1.setTimeZone(TimeZone.getTimeZone("GMT"));

    try {
        Date d = new Date();
        String s3 = sdfGMT1.format(d);
        // Store s3 in DB.
        // ...
        // Retrieve s3 from database, using GMT sdf.
        Date d2 = sdfGMT1.parse(s3);
        String s10 = sdfGMT1.format(d2);
    } catch (Exception e) {
        e.printStackTrace();
    }       
}

Hope below code will help you.

    DateFormat formatDate = new SimpleDateFormat(ISO_DATE_TIME_PATTERN);
    formatDate.setTimeZone(TimeZone.getTimeZone("UTC")); 
    formatDate.parse(dateString);

You can’t

First, you are asking the impossible. An old-fashioned Date object hasn’t got, as in cannot have a time zone or GMT offset.

But the date is always is interpreted in my local time zone.

I suppose that you have printed the Date or done something else that implicitly calls it toString method. I believe that this is the only time that the Date is interpreted in your time zone. More precisely in the current default time zone of your JVM. On the other hand this is unavoidable. Date.toString() does behave in that way, it picks up the JVM’s time zone setting and uses it for rendering the string to be returned.

You can with java.time

You shouldn’t use a Date, though. That class is poorly designed and fortunately long outdated. Also java.time, the modern Java date and time API that replaces it, has a class or two for dates and times with offset from GMT or UTC. I am considering GMT and UTC synonymous for now, strictly speaking they are not.

    OffsetDateTime now = OffsetDateTime.now(ZoneOffset.UTC);
    System.out.println("Time now in UTC (GMT) is " + now);

When I ran this snippet just now, the output was:

Time now in UTC (GMT) is 2019-06-17T11:51:38.246188Z

The trailing Z of the output means UTC.

Use this link to download and install Visual C++ 2015 Build Tools. It will automatically download visualcppbuildtools_full.exe and install Visual C++ 14.0 without actually installing Visual Studio. After the installation completes, retry pip install and you won't get the error again.

I have tested it on following platform and versions:

Python 3.6 on Windows 7 64-bit
Python 3.7 on Windows Server 2016 (64-bit system)
Python 3.8 on Windows 10 64-bit

you can easily access elements by index , by use System.Linq

Here is the sample

First add using in your class file

using System.Linq;

Then

yourDictionaryData.ElementAt(i).Key
yourDictionaryData.ElementAt(i).Value

Hope this helps.

Please use the following query to list the tables in your DB.

select name from sys.Tables 

In Addition, you can add a where condition, to skip system generated tables and lists only user created table by adding type ='U'

Ex : select name from sys.Tables where type ='U'

I had this problem in a fledgling Express API project.

The offending server code in src/server/server.js:

import express from 'express';
import {initialDonationItems, initialExpenditureItems} from "./DemoData";

const server = express();

server.get('/api/expenditures', (req, res) => {
  res.type('json');
  res.send(initialExpenditureItems);
});

server.get('/api/donations', (req, res) => {
  res.type('json');
  res.send(initialDonationItems);
});

server.listen(4242, () => console.log('Server is running...'));

Here were my dependencies:

{
  "name": "contributor-api",
  "version": "0.0.1",
  "description": "A Node backend to provide storage services",
  "scripts": {
    "dev-server": "nodemon --exec babel-node src/server/server.js --ignore dist/",
    "test": "jest tests"
  },
  "license": "ISC",
  "dependencies": {
    "@babel/core": "^7.9.6",
    "@babel/node": "^7.8.7",
    "babel-loader": "^8.1.0",
    "express": "^4.17.1",
    "mysql2": "^2.1.0",
    "sequelize": "^5.21.7",
    "sequelize-cli": "^5.5.1"
  },
  "devDependencies": {
    "jest": "^25.5.4",
    "nodemon": "^2.0.3"
  }
}

And here was the runner that threw the error:

nodemon --exec babel-node src/server/server.js --ignore dist

This was frustrating, as I had a similar Express project that worked fine.

The solution was firstly to add this dependency:

npm install @babel/preset-env

And then to wire it in using a babel.config.js in the project root:

module.exports = {
  presets: ['@babel/preset-env'],
};

I don't fully grok why this works, but I copied it from an authoritative source, so I am happy to stick with it.

?A fiddle is here.

Here's a very simple no-framework wrapper based on the other answers and articles posted in here:

var http = require('http');
var querystring = require('querystring');

function processPost(request, response, callback) {
    var queryData = "";
    if(typeof callback !== 'function') return null;

    if(request.method == 'POST') {
        request.on('data', function(data) {
            queryData += data;
            if(queryData.length > 1e6) {
                queryData = "";
                response.writeHead(413, {'Content-Type': 'text/plain'}).end();
                request.connection.destroy();
            }
        });

        request.on('end', function() {
            request.post = querystring.parse(queryData);
            callback();
        });

    } else {
        response.writeHead(405, {'Content-Type': 'text/plain'});
        response.end();
    }
}

Usage example:

http.createServer(function(request, response) {
    if(request.method == 'POST') {
        processPost(request, response, function() {
            console.log(request.post);
            // Use request.post here

            response.writeHead(200, "OK", {'Content-Type': 'text/plain'});
            response.end();
        });
    } else {
        response.writeHead(200, "OK", {'Content-Type': 'text/plain'});
        response.end();
    }

}).listen(8000);

To make an example of Clairton Luz work, you need to run in the FXApplicationThread and insert into Platform.runLater method your code snippet:

  Platform.runLater(() -> {
                        Alert alert = new Alert(Alert.AlertType.ERROR);
                        alert.setTitle("Error Dialog");
                        alert.setHeaderText("No information.");

                        alert.showAndWait();
                    }
            );

Otherwise, you'll get: java.lang.IllegalStateException: Not on FX application thread

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

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

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

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

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

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

This is a variant of the list comprehension answer given by @psun.

By switching the output value, you can actually extract the matching pattern from the list comprehension (something not possible with the any() approach by @Lauritz-v-Thaulow)

extensionsToCheck = ['.pdf', '.doc', '.xls']
url_string = 'http://.../foo.doc'

print [extension for extension in extensionsToCheck if(extension in url_string)]

['.doc']`

You can furthermore insert a regular expression if you want to collect additional information once the matched pattern is known (this could be useful when the list of allowed patterns is too long to write into a single regex pattern)

print [re.search(r'(\w+)'+extension, url_string).group(0) for extension in extensionsToCheck if(extension in url_string)]

['foo.doc']

Since the SERVICE_USER table is not a pure join table, but has additional functional fields (blocked), you must map it as an entity, and decompose the many to many association between User and Service into two OneToMany associations : One User has many UserServices, and one Service has many UserServices.

You haven't shown us the most important part : the mapping and initialization of the relationships between your entities (i.e. the part you have problems with). So I'll show you how it should look like.

If you make the relationships bidirectional, you should thus have

class User {
    @OneToMany(mappedBy = "user")
    private Set<UserService> userServices = new HashSet<UserService>();
}

class UserService {
    @ManyToOne
    @JoinColumn(name = "user_id")
    private User user;

    @ManyToOne
    @JoinColumn(name = "service_code")
    private Service service;

    @Column(name = "blocked")
    private boolean blocked;
}

class Service {
    @OneToMany(mappedBy = "service")
    private Set<UserService> userServices = new HashSet<UserService>();
}

If you don't put any cascade on your relationships, then you must persist/save all the entities. Although only the owning side of the relationship (here, the UserService side) must be initialized, it's also a good practice to make sure both sides are in coherence.

User user = new User();
Service service = new Service();
UserService userService = new UserService();

user.addUserService(userService);
userService.setUser(user);

service.addUserService(userService);
userService.setService(service);

session.save(user);
session.save(service);
session.save(userService);

The characters you are reading on your screen now each have a numerical value. In the ASCII format, for example, the letter 'A' is 65, 'B' is 66, and so on. If you look at a table of characters available in ASCII you will see that it isn't much use for someone who wishes to write something in Mandarin, Arabic, or Japanese. For characters / words from those languages to be displayed we needed another system of encoding them to and from numbers stored in computer memory.

UTF-8 is just one of the encoding methods that were invented to implement this requirement. It lets you write text in all kinds of languages, so French accents will appear perfectly fine, as will text like this

???? ????? (Bzia zbasa), ???????, Ç'kemi, ???, and even right-to-left writing such as this ?????? ?????

If you copy and paste the above text into notepad and then try to save the file as ANSI (another format) you will receive a warning that saving in this format will lose some of the formatting. Accept it, then re-load the text file and you'll see something like this

???? ????? (Bzia zbasa), ???????, Ç'kemi, ???, and even right-to-left writing such as this ?????? ?????

There is a <hr> tag for horizontal line. It can be used with CSS to make horizontal line also:

.divider{_x000D_
    margin-left: 5px;_x000D_
    margin-right: 5px;_x000D_
    height: 100px;_x000D_
    width: 1px;_x000D_
    background-color: red;_x000D_
}

<hr class="divider">

The width property determines the thickness of the line. The height property determines the length of the line. The background-color property determines the color of the line.

When we use multiple and (where) condition with last (where + or where) the where condition fails most of the time. for that we can use the nested where function with parameters passing in that.

$feedsql = DB::table('feeds as t1')
                   ->leftjoin('groups as t2', 't1.groups_id', '=', 't2.id')
                    ->where('t2.status', 1)
                    ->whereRaw("t1.published_on <= NOW()") 
                    >whereIn('t1.groupid', $group_ids)
                   ->where(function($q)use ($userid) {
                            $q->where('t2.contact_users_id', $userid)
                            ->orWhere('t1.users_id', $userid);
                     })
                  ->orderBy('t1.published_on', 'desc')->get();

The above query validate all where condition then finally checks where t2.status=1 and (where t2.contact_users_id='$userid' or where t1.users_id='$userid')

It's pretty simple, just use Android:CenterInParent="true" to center both in horizontal and vertical, or use Android:Horizontal="true" to center in horizontal and Android:Vertical="true"

And make sure you write all this in RelaytiveLayout

Just searched for the docs, and found this:

Containment Operator: The in operator performs containment test. It returns true if the left operand is contained in the right:

{# returns true #}

{{ 1 in [1, 2, 3] }}

{{ 'cd' in 'abcde' }}

It turns out setting these configuration properties is pretty straight forward, but the official documentation is more general so it might be hard to find when searching specifically for connection pool configuration information.

To set the maximum pool size for tomcat-jdbc, set this property in your .properties or .yml file:

spring.datasource.maxActive=5

You can also use the following if you prefer:

spring.datasource.max-active=5

You can set any connection pool property you want this way. Here is a complete list of properties supported by tomcat-jdbc.

To understand how this works more generally you need to dig into the Spring-Boot code a bit.

Spring-Boot constructs the DataSource like this (see here, line 102):

@ConfigurationProperties(prefix = DataSourceAutoConfiguration.CONFIGURATION_PREFIX)
@Bean
public DataSource dataSource() {
    DataSourceBuilder factory = DataSourceBuilder
            .create(this.properties.getClassLoader())
            .driverClassName(this.properties.getDriverClassName())
            .url(this.properties.getUrl())
            .username(this.properties.getUsername())
            .password(this.properties.getPassword());
    return factory.build();
}

The DataSourceBuilder is responsible for figuring out which pooling library to use, by checking for each of a series of know classes on the classpath. It then constructs the DataSource and returns it to the dataSource() function.

At this point, magic kicks in using @ConfigurationProperties. This annotation tells Spring to look for properties with prefix CONFIGURATION_PREFIX (which is spring.datasource). For each property that starts with that prefix, Spring will try to call the setter on the DataSource with that property.

The Tomcat DataSource is an extension of DataSourceProxy, which has the method setMaxActive().

And that's how your spring.datasource.maxActive=5 gets applied correctly!

What about other connection pools

I haven't tried, but if you are using one of the other Spring-Boot supported connection pools (currently HikariCP or Commons DBCP) you should be able to set the properties the same way, but you'll need to look at the project documentation to know what is available.

An update

Now on windows no need to run react-native start. The packager will run automatically.

var timeout_check_change_class;

function check_change_class( selector )
{
    $(selector).each(function(index, el) {
        var data_old_class = $(el).attr('data-old-class');
        if (typeof data_old_class !== typeof undefined && data_old_class !== false) 
        {

            if( data_old_class != $(el).attr('class') )
            {
                $(el).trigger('change_class');
            }
        }

        $(el).attr('data-old-class', $(el).attr('class') );

    });

    clearTimeout( timeout_check_change_class );
    timeout_check_change_class = setTimeout(check_change_class, 10, selector);
}
check_change_class( '.breakpoint' );


$('.breakpoint').on('change_class', function(event) {
    console.log('haschange');
});

You can use httpx for that.

import httpx

async def get_async(url):
    async with httpx.AsyncClient() as client:
        return await client.get(url)

urls = ["http://google.com", "http://wikipedia.org"]

# Note that you need an async context to use `await`.
await asyncio.gather(*map(get_async, urls))

if you want a functional syntax, the gamla lib wraps this into get_async.

Then you can do

await gamla.map(gamla.get_async(10))(["http://google.com", "http://wikipedia.org"])

The 10 is the timeout in seconds.

(disclaimer: I am its author)

You're missing the binding of the method in the constructor. This is how React suggests that you do it:

class Whatever {
  constructor() {
    super();
    this.onKeyPressed = this.onKeyPressed.bind(this);
  }

  onKeyPressed(e) {
    // your code ...
  }

  render() {
    return (<div onKeyDown={this.onKeyPressed} />);
  }
}

There are other ways of doing this, but this will be the most efficient at runtime.

The best reusable option is to implement the interface Iterable and override the method iterator().

Here's an example of a an ArrayList like class implementing the interface, in which you override the method Iterator().

import java.util.Iterator;

public class SOList<Type> implements Iterable<Type> {

    private Type[] arrayList;
    private int currentSize;

    public SOList(Type[] newArray) {
        this.arrayList = newArray;
        this.currentSize = arrayList.length;
    }

    @Override
    public Iterator<Type> iterator() {
        Iterator<Type> it = new Iterator<Type>() {

            private int currentIndex = 0;

            @Override
            public boolean hasNext() {
                return currentIndex < currentSize && arrayList[currentIndex] != null;
            }

            @Override
            public Type next() {
                return arrayList[currentIndex++];
            }

            @Override
            public void remove() {
                throw new UnsupportedOperationException();
            }
        };
        return it;
    }
}

This class implements the Iterable interface using Generics. Considering you have elements to the array, you will be able to get an instance of an Iterator, which is the needed instance used by the "foreach" loop, for instance.

You can just create an anonymous instance of the iterator without creating extending Iterator and take advantage of the value of currentSize to verify up to where you can navigate over the array (let's say you created an array with capacity of 10, but you have only 2 elements at 0 and 1). The instance will have its owner counter of where it is and all you need to do is to play with hasNext(), which verifies if the current value is not null, and the next(), which will return the instance of your currentIndex. Below is an example of using this API...

public static void main(String[] args) {
    // create an array of type Integer
    Integer[] numbers = new Integer[]{1, 2, 3, 4, 5};

    // create your list and hold the values.
    SOList<Integer> stackOverflowList = new SOList<Integer>(numbers);

    // Since our class SOList is an instance of Iterable, then we can use it on a foreach loop
    for(Integer num : stackOverflowList) {
        System.out.print(num);
    }

    // creating an array of Strings
    String[] languages = new String[]{"C", "C++", "Java", "Python", "Scala"};

    // create your list and hold the values using the same list implementation.
    SOList<String> languagesList = new SOList<String>(languages);

    System.out.println("");
    // Since our class SOList is an instance of Iterable, then we can use it on a foreach loop
    for(String lang : languagesList) {
        System.out.println(lang);
    }
}
// will print "12345
//C
//C++
//Java
//Python
//Scala

If you want, you can iterate over it as well using the Iterator instance:

// navigating the iterator
while (allNumbers.hasNext()) {
    Integer value = allNumbers.next();
    if (allNumbers.hasNext()) {
        System.out.print(value + ", ");
    } else {
        System.out.print(value);
    }
} 
// will print 1, 2, 3, 4, 5

The foreach documentation is located at http://download.oracle.com/javase/1,5.0/docs/guide/language/foreach.html. You can take a look at a more complete implementation at my personal practice google code.

Now, to get the effects of what you need I think you need to plug a concept of a filter in the Iterator... Since the iterator depends on the next values, it would be hard to return true on hasNext(), and then filter the next() implementation with a value that does not start with a char "a" for instance. I think you need to play around with a secondary Interator based on a filtered list with the values with the given filter.

I was getting selectNode() param 1 is not of type node error.

changed the code to this and its working. (for chrome)

function copy_data(containerid) {_x000D_
  var range = document.createRange();_x000D_
  range.selectNode(containerid); //changed here_x000D_
  window.getSelection().removeAllRanges(); _x000D_
  window.getSelection().addRange(range); _x000D_
  document.execCommand("copy");_x000D_
  window.getSelection().removeAllRanges();_x000D_
  alert("data copied");_x000D_
}

<div id="select_txt">This will be copied to clipboard!</div>_x000D_
<button type="button" onclick="copy_data(select_txt)">copy</button>_x000D_
<br>_x000D_
<hr>_x000D_
<p>Try paste it here after copying</p>_x000D_
<textarea></textarea>

Without explicitly providing the type as in command.Parameters.Add("@ID", SqlDbType.Int);, it will try to implicitly convert the input to what it is expecting.

The downside of this, is that the implicit conversion may not be the most optimal of conversions and may cause a performance hit.

Notice : in case when you just need to change some specific collation use condition like this :

WHERE c.object_id = OBJECT_ID(@table) AND (t.Name LIKE '%char%' OR t.Name LIKE '%text%') 
    AND c.collation_name = 'collation to change'

e.g. NOT the : AND c.collation_name <> @collate

In my case, I had correct / specified collation of some columns and didn't want to change them.

It seems that you need to pass a flag "-l, --log-file"

https://github.com/elastic/kibana/issues/3407

Usage: kibana [options]

Kibana is an open source (Apache Licensed), browser based analytics and search dashboard for Elasticsearch.

Options:

    -h, --help                 output usage information
    -V, --version              output the version number
    -e, --elasticsearch <uri>  Elasticsearch instance
    -c, --config <path>        Path to the config file
    -p, --port <port>          The port to bind to
    -q, --quiet                Turns off logging
    -H, --host <host>          The host to bind to
    -l, --log-file <path>      The file to log to
    --plugins <path>           Path to scan for plugins

If you use the init script to run as a service, maybe you will need to customize it.

If you are using torch you can do:

import torch.multiprocessing as mp

mp.cpu_count()

Thanks @Clint for the great answer:

Just wanted to highlight how easy it was to solve this using the Expando Object:

    var dynamicObject = new ExpandoObject() as IDictionary<string, Object>;
    foreach (var property in properties) {
        dynamicObject.Add(property.Key,property.Value);
    }

This works perfectly fine with me :)

Path.GetFileName(path.TrimEnd('\\')

You can make an AMI of an existing instance, and then launch other instances using that AMI.

I done this way:

$scope.printDiv = function (div) {
  var docHead = document.head.outerHTML;
  var printContents = document.getElementById(div).outerHTML;
  var winAttr = "location=yes, statusbar=no, menubar=no, titlebar=no, toolbar=no,dependent=no, width=865, height=600, resizable=yes, screenX=200, screenY=200, personalbar=no, scrollbars=yes";

  var newWin = window.open("", "_blank", winAttr);
  var writeDoc = newWin.document;
  writeDoc.open();
  writeDoc.write('<!doctype html><html>' + docHead + '<body onLoad="window.print()">' + printContents + '</body></html>');
  writeDoc.close();
  newWin.focus();
}

It should be simpler!

Duration.between(startLocalDateTime, endLocalDateTime).toMillis();

You can convert millis to whatever unit you like:

String.format("%d minutes %d seconds", 
  TimeUnit.MILLISECONDS.toMinutes(millis),
  TimeUnit.MILLISECONDS.toSeconds(millis) - 
  TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)));

JavascriptExecutor js = (JavascriptExecutor)driver;
js.executeScript("document.querySelector('attributeValue').value='new value'");

If you want your script to return values, just do return [1,2,3] from a function wrapping your code but then you'd have to import your script from another script to even have any use for that information:

Return values (from a wrapping-function)

(again, this would have to be run by a separate Python script and be imported in order to even do any good):

import ...
def main():
    # calculate stuff
    return [1,2,3]

Exit codes as indicators

(This is generally just good for when you want to indicate to a governor what went wrong or simply the number of bugs/rows counted or w/e. Normally 0 is a good exit and >=1 is a bad exit but you could inter-prate them in any way you want to get data out of it)

import sys
# calculate and stuff
sys.exit(100)

And exit with a specific exit code depending on what you want that to tell your governor. I used exit codes when running script by a scheduling and monitoring environment to indicate what has happened.

(os._exit(100) also works, and is a bit more forceful)

Stdout as your relay

If not you'd have to use stdout to communicate with the outside world (like you've described). But that's generally a bad idea unless it's a parser executing your script and can catch whatever it is you're reporting to.

import sys
# calculate stuff
sys.stdout.write('Bugs: 5|Other: 10\n')
sys.stdout.flush()
sys.exit(0)

Are you running your script in a controlled scheduling environment then exit codes are the best way to go.

Files as conveyors

There's also the option to simply write information to a file, and store the result there.

# calculate
with open('finish.txt', 'wb') as fh:
    fh.write(str(5)+'\n')

And pick up the value/result from there. You could even do it in a CSV format for others to read simplistically.

Sockets as conveyors

If none of the above work, you can also use network sockets locally *(unix sockets is a great way on nix systems). These are a bit more intricate and deserve their own post/answer. But editing to add it here as it's a good option to communicate between processes. Especially if they should run multiple tasks and return values.

UPDATE: Suggest using Dataframes, plus something like ... .write.mode(SaveMode.Overwrite) ....

Handy pimp:

implicit class PimpedStringRDD(rdd: RDD[String]) {
    def write(p: String)(implicit ss: SparkSession): Unit = {
      import ss.implicits._
      rdd.toDF().as[String].write.mode(SaveMode.Overwrite).text(p)
    }
  }

For older versions try

yourSparkConf.set("spark.hadoop.validateOutputSpecs", "false")
val sc = SparkContext(yourSparkConf)

In 1.1.0 you can set conf settings using the spark-submit script with the --conf flag.

WARNING (older versions): According to @piggybox there is a bug in Spark where it will only overwrite files it needs to to write it's part- files, any other files will be left unremoved.

"This is my string with date in specified format $($theDate.ToString('u'))"

or

"This is my string with date in specified format $(Get-Date -format 'u')"

The sub-expression ($(...)) can include arbitrary expressions calls.

MSDN Documents both standard and custom DateTime format strings.

Left bit shifting to multiply by any power of two and right bit shifting to divide by any power of two.

For example, x = x * 2; can also be written as x<<1 or x = x*8 can be written as x<<3 (since 2 to the power of 3 is 8). Similarly x = x / 2; is x>>1 and so on.

Have a go with this, as this is how I would do it :)

SELECT * 
FROM fab_scheduler
WHERE custid = '123456'
AND CURDATE() = DATE(DATE_ADD(eventdate, INTERVAL 1 DAY))

session_start();    
echo session_id();

This will help you

echo '<pre>';

$output = print_r($array,1);

echo '</pre>';

EDIT

using echo '<pre>'; is useless, but var_export($var); will do the thing which you are expecting.

If you don't like anonymous functions:

try {
    DB::connection()->pdo->beginTransaction();
    // database queries here
    DB::connection()->pdo->commit();
} catch (\PDOException $e) {
    // Woopsy
    DB::connection()->pdo->rollBack();
}

Update: For laravel 4, the pdo object isn't public anymore so:

try {
    DB::beginTransaction();
    // database queries here
    DB::commit();
} catch (\PDOException $e) {
    // Woopsy
    DB::rollBack();
}

Or just in GlobalConstants.swift:

import Foundation

let someNotification = "aaaaNotification"

you can kinda hack it with the min-height declaration

<div style="min-height: 100%">stuff</div>

Make sure you aren't using a Windows' directory separator character (backslash) in your path names in your .conf file, even if you are on Windows. Apache doesn't understand them but will still start up and then output a 403 Forbidden Message.

uint8, uint16, uint32, and uint64 are probably Microsoft-specific types.

As of the 1999 standard, C supports standard typedefs with similar meanings, defined in <stdint.h>: uint8_t, uint16_t, uint32_t, and uint64_t. I'll assume that the Microsoft-specific types are defined similarly. Microsoft does support <stdint.h>, at least as of Visual Studio 2010, but older code may use uint8 et al.

The predefined types char, short, int et al have sizes that vary from one C implementation to another. The C standard has certain minimum requirements (char is at least 8 bits, short and int are at least 16, long is at least 32, and each type in that list is at least as wide as the previous type), but permits some flexibility. For example, I've seen systems where int is 16, 32, or 64 bits.

char is almost always exactly 8 bits, but it's permitted to be wider. And plain char may be either signed or unsigned.

uint8_t is required to be an unsigned integer type that's exactly 8 bits wide. It's likely to be a typedef for unsigned char, though it might be a typedef for plain char if plain char happens to be unsigned. If there is no predefined 8-bit unsigned type, then uint8_t will not be defined at all.

Similarly, each uintN_t type is an unsigned type that's exactly N bits wide.

In addition, <stdint.h> defines corresponding signed intN_t types, as well as int_fastN_t and int_leastN_t types that are at least the specified width.

The [u]intN_t types are guaranteed to have no padding bits, so the size of each is exactly N bits. The signed intN_t types are required to use a 2's-complement representation.

Although uint32_t might be the same as unsigned int, for example, you shouldn't assume that. Use unsigned int when you need an unsigned integer type that's at least 16 bits wide, and that's the "natural" size for the current system. Use uint32_t when you need an unsigned integer type that's exactly 32 bits wide.

(And no, uint64 or uint64_t is not the same as double; double is a floating-point type.)

It seems that ARM64 was created by Apple and AARCH64 by the others, most notably GNU/GCC guys.

After some googling I found this link:

The LLVM 64-bit ARM64/AArch64 Back-Ends Have Merged

So it makes sense, iPad calls itself ARM64, as Apple is using LLVM, and Edge uses AARCH64, as Android is using GNU GCC toolchain.

I was getting this error with my Nexus 10. I tried all of the answers I could find, and then I realized I was using a different USB port than usual. I switched to using the port I usually use, which is on the other side of my laptop, and the authorization popped up on my tablet!

Some clarifications (not really an answer)

In kubernetes, every pod gets assigned an IP address, and every container in the pod gets assigned that same IP address. Thus, as Alex Robinson stated in his answer, you can just use hostname -i inside your container to get the pod IP address.

I tested with a pod running two dumb containers, and indeed hostname -i was outputting the same IP address inside both containers. Furthermore, that IP was equivalent to the one obtained using kubectl describe pod from outside, which validates the whole thing IMO.

However, PiersyP's answer seems more clean to me.

Sources

From kubernetes docs:

The applications in a pod all use the same network namespace (same IP and port space), and can thus “find” each other and communicate using localhost. Because of this, applications in a pod must coordinate their usage of ports. Each pod has an IP address in a flat shared networking space that has full communication with other physical computers and pods across the network.

Another piece from kubernetes docs:

Until now this document has talked about containers. In reality, Kubernetes applies IP addresses at the Pod scope - containers within a Pod share their network namespaces - including their IP address. This means that containers within a Pod can all reach each other’s ports on localhost.

Your second date is before your first date (ie. you are querying between September 29 2010 and January 30 2010). Try reversing the order of the dates:

SELECT *
FROM `objects`
WHERE (date_field BETWEEN '2010-01-30 14:15:55' AND '2010-09-29 10:15:55')

You can use the "Join" function to create a single string out of the array of labels, like this:

=Join(Parameters!Product.Label, ",")

In my case, I had installed the data directory to a different location. So the data directory really wasn't in the default location. Therefore, when I ran the mysqld command from the command prompt, I had to specify the data directory manually:

mysqld --datadir=D:/MySQLData/Data

Here's the documentation for mysqld command-line arguments.

Just in case if you are using .BAT file as Windows Service, I would suggest to uninstall the Windows service and reinstall it again after changing the %JAVA_HOME% to point to the right Java version..

Use the std::vector::vector(count, value) constructor that accepts an initial size and a default value:

std::vector<std::vector<int> > fog(
    ROW_COUNT,
    std::vector<int>(COLUMN_COUNT)); // Defaults to zero initial value

If a value other than zero, say 4 for example, was required to be the default then:

std::vector<std::vector<int> > fog(
    ROW_COUNT,
    std::vector<int>(COLUMN_COUNT, 4));

I should also mention uniform initialization was introduced in C++11, which permits the initialization of vector, and other containers, using {}:

std::vector<std::vector<int> > fog { { 1, 1, 1 },
                                    { 2, 2, 2 } };
                           

This is my version of check ping function. May be if well be usefull for someone:

if response == 0:
return "alive"
else:

else:
response = os.system("ping -c 1 -W 0.5" + host + "> /dev/null")
if response == 1:
return "alive"
else:
return "not alive"

This error would suggest that User::where('email', '=', $userEmail)->first() is returning null, rather than a problem with updating your model.

Check that you actually have a User before attempting to change properties on it, or use the firstOrFail() method.

$UpdateDetails = User::where('email', $userEmail)->first();

if (is_null($UpdateDetails)) {
    return false;
}

or using the firstOrFail() method, theres no need to check if the user is null because this throws an exception (ModelNotFoundException) when a model is not found, which you can catch using App::error() http://laravel.com/docs/4.2/errors#handling-errors

$UpdateDetails = User::where('email', $userEmail)->firstOrFail();

FYI, If you're using inline styles or modifying the DOM directly (for instance adding an element), workspaces don't solve this problem. That's because the DOM is living in memory and there's not an actual file associated with the active state of the DOM.

For that, I like to take a "before" and "after" snapshot of the dom from the console: copy(document.getElementsByTagName('html')[0].outerHTML)

Then I place it in a diff tool to see my changes.

In short "How do I remove from a map while iterating it?"

• With old map impl: You can't
• With new map impl: almost as @KerrekSB suggested. But there are some syntax issues in what he posted.

From GCC map impl (note GXX_EXPERIMENTAL_CXX0X):

Use text-center instead of center-block.

Or use center-block on the span element (I did the column wider so you can see the alignment better):

<div class="row">
   <div class="col-xs-10" style="background-color:#123;">
      <span class="center-block" style="width:100px; background-color:#ccc;">abc</span>
   </div>

Easy and better than str_replace:

    "w" => "W",
    "d" => "D");

    $word = "http://desiweb.ir";
    echo strtr($word,$arr);
?>

If you run any of them on SQL Server based on a linux machine, you will get these errors:

Msg 16202, Level 15, State 1, Line 1
Keyword or statement option 'bulkadmin' is not supported on the 'Linux' platform.

Msg 16202, Level 15, State 3, Line 1
Keyword or statement option 'ADMINISTER BULK OPERATIONS' is not supported on the 'Linux' platform.

Check the docs.

Requires INSERT and ADMINISTER BULK OPERATIONS permissions. In Azure SQL Database, INSERT and ADMINISTER DATABASE BULK OPERATIONS permissions are required. ADMINISTER BULK OPERATIONS permissions or the bulkadmin role is not supported for SQL Server on Linux. Only the sysadmin can perform bulk inserts for SQL Server on Linux.

Solution for Linux

ALTER SERVER ROLE [sysadmin] ADD MEMBER [login_name];

Add to your settings.py:

LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
        'file': {
            'level': 'DEBUG',
            'class': 'logging.FileHandler',
            'filename': 'debug.log',
        },
    },
    'loggers': {
        'django': {
            'handlers': ['file'],
            'level': 'DEBUG',
            'propagate': True,
        },
    },
}

And it will create a file called debug.log in the root of your. https://docs.djangoproject.com/en/1.10/topics/logging/

Here is a solution I use in one of my project.

network_utils.telnet

import socket
from timeit import default_timer as timer

def telnet(hostname, port=23, timeout=1):
    start = timer()
    connection = socket.socket()
    connection.settimeout(timeout)
    try:
        connection.connect((hostname, port))
        end = timer()
        delta = end - start
    except (socket.timeout, socket.gaierror) as error:
        logger.debug('telnet error: ', error)
        delta = None
    finally:
        connection.close()

    return {
        hostname: delta
    }

Tests

def test_telnet_is_null_when_host_unreachable(self):
    hostname = 'unreachable'

    response = network_utils.telnet(hostname)

    self.assertDictEqual(response, {'unreachable': None})

def test_telnet_give_time_when_reachable(self):
    hostname = '127.0.0.1'

    response = network_utils.telnet(hostname, port=22)

    self.assertGreater(response[hostname], 0)

Assuming you're currently on the branch you want to rename:

git branch -m newname

This is documented in the manual for git-branch, which you can view using

man git-branch

or

git help branch

Specifically, the command is

git branch (-m | -M) [<oldbranch>] <newbranch>

where the parameters are:

   <oldbranch>
       The name of an existing branch to rename.

   <newbranch>
       The new name for an existing branch. The same restrictions as for <branchname> apply.

<oldbranch> is optional, if you want to rename the current branch.

This (Ondrej's answer):

Foo[] array = list.toArray(new Foo[0]);

Is the most common idiom I see. Those who are suggesting that you use the actual list size instead of "0" are misunderstanding what's happening here. The toArray call does not care about the size or contents of the given array - it only needs its type. It would have been better if it took an actual Type in which case "Foo.class" would have been a lot clearer. Yes, this idiom generates a dummy object, but including the list size just means that you generate a larger dummy object. Again, the object is not used in any way; it's only the type that's needed.

I had a similar issue using like pattern '%_%' did not work - as the question indicates :-)

Using '%\_%' did not work either as this first \ is interpreted "before the like".

Using '%\\_%' works. The \\ (double backslash) is first converted to single \ (backslash) and then used in the like pattern.

It could be done by getting the page title by Selenium and do assertion by using TestNG.

1. Import Assert class in the import section:

   `import org.testng.Assert;`
   

2. Create a WebDriver object:

   WebDriver driver=new FirefoxDriver();

3. Apply this to assert the title of the page:

   Assert.assertEquals("Expected page title", driver.getTitle());

My dad moved his office after 30 year and they need to update the address in the header of their Crystal Reports 7 (1997!) based billing system.

After buying old copies of Access 97 and Visual Studio 2003 Pro, I found out that both programs were too new - they could open the RPT files, but they saved them with an updated version that would not open in the billing system.

I ended up being able to make the changes using this life-saver program...

http://www.softwareforces.com/Products/rpt-inspector-professional-suite-for-crystal-reports

It was available with a 10 day free trial, and I only needed about 10 minutes to make my changes. That said, I would have happily paid whatever they asked for it. :)

Some hints:

1. When I opened my RPT files, I got an error saving the database could not be found. I ignored this error and everything worked fine.
2. Because my RPT files were Crystal Reports version 7, I had to go into Options->Misc and tell the program to save in the old format...

You can add it as script file. save the txt file with js suffix

in the head section add

<script src="fileName.js"></script>

If you are using MySQL the closest you can get is full-text search:

Full-Text Search, MySQL Documentation

to resolve this kind of problem you should add two jar in your dependency POM (if use Maven)

<dependency>
    <groupId>asm</groupId>
    <artifactId>asm</artifactId>
    <version>3.3.1</version>
</dependency>

<dependency>
    <groupId>cglib</groupId>
    <artifactId>cglib</artifactId>
    <version>3.1</version>

You can directly use following javascript

((JavascriptExecutor)driver).executeScript("document.getElementById('fromDate').setAttribute('value','10 Jan 2013')")

Use pointers as your function parameters. Then use them to return multiple value.

What Worked for me, while having I have more than 1 user on my computer.

Using terminal:

• Running brew doctor
  • Seeing multiple /usr/local/... isn't writable error's
• Disabling Mac's System Integrity Protection: https://apple.stackexchange.com/a/208481/55628
• Run the following
• sudo chown -R $(whoami) /usr/local/*
• brew doctor && brew upgrade && brew doctor

EDIT 1:

FYI - Please be Advised this causes an issue with running MySQL on your MAC.

To be able to start my local server, I had to run:

sudo chown -R mysql:mysql /usr/local/mysql/data

After you run this you can start your local MySQL Server.

You need to configure the security group as stated by cyraxjoe. Along with that you also need to open System port. Steps to open port in windows :-

1. On the Start menu, click Run, type WF.msc, and then click OK.
2. In the Windows Firewall with Advanced Security, in the left pane, right-click Inbound Rules, and then click New Rule in the action pane.
3. In the Rule Type dialog box, select Port, and then click Next.
4. In the Protocol and Ports dialog box, select TCP. Select Specific local ports, and then type the port number , such as 8787 for the default instance. Click Next.
5. In the Action dialog box, select Allow the connection, and then click Next.
6. In the Profile dialog box, select any profiles that describe the computer connection environment when you want to connect , and then click Next.
7. In the Name dialog box, type a name and description for this rule, and then click Finish.

I always go back to this article SQL Server 2005 XQuery and XML-DML - Part 1 to know how to use the XML features in SQL Server 2005.

For basic XPath know-how, I'd recommend the W3Schools tutorial.

You are right that CSS positioning is the way to go. Here's a quick run down:

position: relative will layout an element relative to itself. In other words, the elements is laid out in normal flow, then it is removed from normal flow and offset by whatever values you have specified (top, right, bottom, left). It's important to note that because it's removed from flow, other elements around it will not shift with it (use negative margins instead if you want this behaviour).

However, you're most likely interested in position: absolute which will position an element relative to a container. By default, the container is the browser window, but if a parent element either has position: relative or position: absolute set on it, then it will act as the parent for positioning coordinates for its children.

To demonstrate:

#container {_x000D_
  position: relative;_x000D_
  border: 1px solid red;_x000D_
  height: 100px;_x000D_
}_x000D_
_x000D_
#box {_x000D_
  position: absolute;_x000D_
  top: 50px;_x000D_
  left: 20px;_x000D_
}

<div id="container">_x000D_
  <div id="box">absolute</div>_x000D_
</div>

In that example, the top left corner of #box would be 100px down and 50px left of the top left corner of #container. If #container did not have position: relative set, the coordinates of #box would be relative to the top left corner of the browser view port.

If you prefer not to use regex, you might try

''.join([i for i in s if i.isalpha()])

Recent updates to ggplot (0.9.2+) have overhauled the syntax for themes. Most notably, opts() is now deprecated, having been replaced by theme(). Sandy's answer will still (as of Jan '12) generates a chart, but causes R to throw a bunch of warnings.

Here's updated code reflecting current ggplot syntax:

library(ggplot2)
a <- seq(1,20)
b <- a^0.25
df <- as.data.frame(cbind(a,b))

#base ggplot object
p <- ggplot(df, aes(x = a, y = b))

p +
  #plots the points
  geom_point() +

  #theme with white background
  theme_bw() +

  #eliminates background, gridlines, and chart border
  theme(
    plot.background = element_blank(),
    panel.grid.major = element_blank(),
    panel.grid.minor = element_blank(),
    panel.border = element_blank()
  ) +

  #draws x and y axis line
  theme(axis.line = element_line(color = 'black'))

generates:

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

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

1. Here I am trying to printing the 1 to 10 numbers.
2. One thread trying to print the even numbers and another Thread Odd numbers.

4. Each thread calls particular method 5 times because I am trying to print 10 values only.

You need to wrap your form processing code in a conditional so it doesn't run when you first open the page. Something like so:

if($_POST['num1'] > 0 && $_POST['num2'] > 0 && $_POST['num3'] > 0 && $_POST['num4'] > 0){

  $itemQty = $_POST['num1'];
  $itemCost = $_POST['num2'];
  $itemSale = $_POST['num3'];
  $shipMat = $_POST['num4'];

  $diffPrice = $itemSale - $itemCost;
  $actual = ($diffPrice - $shipMat) * $itemQty;
  $diffPricePercent = (($actual * 100) / $itemCost) / $itemQty ;
}

I am surprised that in almost ten years, no one has posted this approach yet:

If using older versions of bash where &>> isn't available, you also can do:

(cmd 2>&1) >> file.txt

This spawns a subshell, so it's less efficient than the traditional approach of cmd >> file.txt 2>&1, and it consequently won't work for commands that need to modify the current shell (e.g. cd, pushd), but this approach feels more natural and understandable to me:

1. Redirect stderr to stdout.
2. Redirect the new stdout by appending to a file.

Also, the parentheses remove any ambiguity of order, especially if you want to pipe stdout and stderr to another command instead.

Edit: To avoid starting a subshell, you instead could use curly braces instead of parentheses to create a group command:

{ cmd 2>&1; } >> file.txt

(Note that a semicolon (or newline) is required to terminate the group command.)

I understand the question as this: you want to completely replace the contents of one file (or a selection) from upstream. You don't want to affect the index directly (so you would go through add + commit as usual).

Simply do

git checkout remote/branch -- a/file b/another/file

If you want to do this for extensive subtrees and instead wish to affect the index directly use

git read-tree remote/branch:subdir/

You can then (optionally) update your working copy by doing

git checkout-index -u --force

If you want the file to be opened with the default application, I mean without specifying Acrobat or Reader, you can't open the file in the specified page.

On the other hand, if you are Ok with specifying Acrobat or Reader, keep reading:

You can do it without telling the full Acrobat path, like this:

Process myProcess = new Process();    
myProcess.StartInfo.FileName = "acroRd32.exe"; //not the full application path
myProcess.StartInfo.Arguments = "/A \"page=2=OpenActions\" C:\\example.pdf";
myProcess.Start();

If you don't want the pdf to open with Reader but with Acrobat, chage the second line like this:

myProcess.StartInfo.FileName = "Acrobat.exe";

You can query the registry to identify the default application to open pdf files and then define FileName on your process's StartInfo accordingly.

Follow this question for details on doing that: Finding the default application for opening a particular file type on Windows

I've had the above solutions work for me on many occasions, except one; that was after I buggered up an alias file - ie a file that allows the website folder to be located in another location other than the www folder. Here's the solution:

1. Go to c:/wamp/alias
2. Cut all of the alias files and paste in a temp folder somewhere
3. Restart all WAMP services
4. If the WAMP icon goes green, then add each alias file back to the alias folder one by one, restart WAMP, and when WAMP doesn't start, you know that alias file has some bad data in it. So, fix that file or delete it. Your choice.

I solved this problem to add a public setter for all properties, which should be deserialized.

You can try using dictionary as:-

NSDictionary *infoDictionary = [[NSBundle mainBundle]infoDictionary];

NSString *buildVersion = infoDictionary[(NSString*)kCFBundleVersionKey];
NSString *bundleName = infoDictionary[(NSString *)kCFBundleNameKey]

What is a lambda function?

The C++ concept of a lambda function originates in the lambda calculus and functional programming. A lambda is an unnamed function that is useful (in actual programming, not theory) for short snippets of code that are impossible to reuse and are not worth naming.

In C++ a lambda function is defined like this

[]() { } // barebone lambda

or in all its glory

[]() mutable -> T { } // T is the return type, still lacking throw()

[] is the capture list, () the argument list and {} the function body.

The capture list

The capture list defines what from the outside of the lambda should be available inside the function body and how. It can be either:

1. a value: [x]
2. a reference [&x]
3. any variable currently in scope by reference [&]
4. same as 3, but by value [=]

You can mix any of the above in a comma separated list [x, &y].

The argument list

The argument list is the same as in any other C++ function.

The function body

The code that will be executed when the lambda is actually called.

Return type deduction

If a lambda has only one return statement, the return type can be omitted and has the implicit type of decltype(return_statement).

Mutable

If a lambda is marked mutable (e.g. []() mutable { }) it is allowed to mutate the values that have been captured by value.

Use cases

The library defined by the ISO standard benefits heavily from lambdas and raises the usability several bars as now users don't have to clutter their code with small functors in some accessible scope.

C++14

In C++14 lambdas have been extended by various proposals.

Initialized Lambda Captures

An element of the capture list can now be initialized with =. This allows renaming of variables and to capture by moving. An example taken from the standard:

int x = 4;
auto y = [&r = x, x = x+1]()->int {
            r += 2;
            return x+2;
         }();  // Updates ::x to 6, and initializes y to 7.

and one taken from Wikipedia showing how to capture with std::move:

auto ptr = std::make_unique<int>(10); // See below for std::make_unique
auto lambda = [ptr = std::move(ptr)] {return *ptr;};

Generic Lambdas

Lambdas can now be generic (auto would be equivalent to T here if T were a type template argument somewhere in the surrounding scope):

auto lambda = [](auto x, auto y) {return x + y;};

Improved Return Type Deduction

C++14 allows deduced return types for every function and does not restrict it to functions of the form return expression;. This is also extended to lambdas.

Just wanted to share my solution using sqlalchemy and pandas in python 3. Perhaps, one would find it useful.

import sqlalchemy as sa
import pandas as pd
engine = sa.create_engine("postgresql://postgres:my_password@my_host:my_port/my_db")
values = [val1,val2,val3]   
query = sa.text(""" 
                SELECT *
                FROM my_table
                WHERE col1 IN :values; 
""")
query = query.bindparams(values=tuple(values))
df = pd.read_sql(query, engine)

As of Node.js v6.0.0 using the constructor method has been deprecated and the following method should instead be used to construct a new buffer from a base64 encoded string:

var b64string = /* whatever */;
var buf = Buffer.from(b64string, 'base64'); // Ta-da

For Node.js v5.11.1 and below

Construct a new Buffer and pass 'base64' as the second argument:

var b64string = /* whatever */;
var buf = new Buffer(b64string, 'base64'); // Ta-da

If you want to be clean, you can check whether from exists :

if (typeof Buffer.from === "function") {
    // Node 5.10+
    buf = Buffer.from(b64string, 'base64'); // Ta-da
} else {
    // older Node versions, now deprecated
    buf = new Buffer(b64string, 'base64'); // Ta-da
}

404 with Content/Body

res.writeHead(404, {'Content-Type': 'text/plain'});                    // <- redirect
res.write("Looked everywhere, but couldn't find that page at all!\n"); // <- content!
res.end();                                                             // that's all!

Redirect to Https

res.writeHead(302, {'Location': 'https://example.com' + req.url});
res.end();

Just consider where you use this (e.g. only for http request), so you don't get endless redirects ;-)

If you want to install requests directly you can use the "-m" (module) option available to python.

python.exe -m pip install requests

You can do this directly in PowerShell, though you may need to use the full python path (eg. C:\Python27\python.exe) instead of just python.exe.

As mentioned in the comments, if you have added Python to your path you can simply do:

python -m pip install requests

Your last example is invalid JSON. Single quotes are not allowed in JSON except inside strings. In the second example, the single quotes are not in the string, but serve to show the start and end.

See http://www.json.org/ for the specifications.

Should add: Why do you think this: "like I seem to need to in my real code"? Then maybe we can help you come up with the solution.

Try this:

{
    ComboBox cmb = (ComboBox)sender;

    int selectedValue = (int)cmb.SelectedValue;

    ComboboxItem selectedCar = (ComboboxItem)cmb.SelectedItem;
    MessageBox.Show(String.Format("Index: [{0}] CarName={1}; Value={2}", selectedIndex, selectedCar.Text, selecteVal));

You can also use scipy.signal.welch to estimate the power spectral density using Welch’s method. Here is an comparison between np.fft.fft and scipy.signal.welch:

from scipy import signal
import numpy as np
import matplotlib.pyplot as plt

fs = 10e3
N = 1e5
amp = 2*np.sqrt(2)
freq = 1234.0
noise_power = 0.001 * fs / 2
time = np.arange(N) / fs
x = amp*np.sin(2*np.pi*freq*time)
x += np.random.normal(scale=np.sqrt(noise_power), size=time.shape)

# np.fft.fft
freqs = np.fft.fftfreq(time.size, 1/fs)
idx = np.argsort(freqs)
ps = np.abs(np.fft.fft(x))**2
plt.figure()
plt.plot(freqs[idx], ps[idx])
plt.title('Power spectrum (np.fft.fft)')

# signal.welch
f, Pxx_spec = signal.welch(x, fs, 'flattop', 1024, scaling='spectrum')
plt.figure()
plt.semilogy(f, np.sqrt(Pxx_spec))
plt.xlabel('frequency [Hz]')
plt.ylabel('Linear spectrum [V RMS]')
plt.title('Power spectrum (scipy.signal.welch)')
plt.show()

There are two easy ways:

1. In your cpanel Go to cpanel/ softaculous/ wordpress, under the current installation, you will see the websites you have installed with the wordpress. Click the "edit detail" of the particular website and you will see your SQL database username and password.

2. In your server Access your FTP and view the wp-config.php

check your casing, the name is typically stored in upper case

SELECT * FROM all_source WHERE name = 'DAILY_UPDATE' ORDER BY TYPE, LINE;

Alternative option : you can also create a bash cell in jupyter using bash kernel and then pip install geocoder. That should work

To deal with situations where there are a possibility of multiple values (v in your example), I use PIVOT and LISTAGG:

SELECT * FROM
(
  SELECT id, k, v
  FROM _kv 
)
PIVOT 
(
  LISTAGG(v ,',') 
  WITHIN GROUP (ORDER BY k) 
  FOR k IN ('name', 'age','gender','status')
)
ORDER BY id;

Since you want dynamic values, use dynamic SQL and pass in the values determined by running a select on the table data before calling the pivot statement.

• Add import sys as the new topline
• You misspelled "executables" on the last line.
• Remove script = on last line.

The code should now look like:

import sys
from cx_Freeze import setup, Executable

setup(
    name = "On Dijkstra's Algorithm",
    version = "3.1",
    description = "A Dijkstra's Algorithm help tool.",
    executables = [Executable("Main.py", base = "Win32GUI")])

Use the command prompt (cmd) to run python setup.py build. (Run this command from the folder containing setup.py.) Notice the build parameter we added at the end of the script call.

Starting Python 3.8, the standard library provides the NormalDist object as part of the statistics module.

It can be used to get the inverse cumulative distribution function (inv_cdf - inverse of the cdf), also known as the quantile function or the percent-point function for a given mean (mu) and standard deviation (sigma):

from statistics import NormalDist

NormalDist(mu=10, sigma=2).inv_cdf(0.95)
# 13.289707253902943

Which can be simplified for the standard normal distribution (mu = 0 and sigma = 1):

NormalDist().inv_cdf(0.95)
# 1.6448536269514715

In the navigator under SCHEMAS, right click your schema/database and select "Table Data Import Wizard"

Works for mac too.

image.SetAbsolutePosition(1,1);

Try to make Treemap < Integer, Treemap<Integer, obj> >

In java, Treemap is sorted map. And the number of item in row and col wont screw the 2D-index you want to set. Then you can get a col-row table like structure.

You can use goto.

while ( ... ) {
   switch( ... ) {
     case ...:
         goto exit_loop;

   }
}
exit_loop: ;

It looks like you forgot to include the ngRoute module in your dependency for myApp.

In Angular 1.2, they've made ngRoute optional (so you can use third-party route providers, etc.) and you have to explicitly depend on it in modules, along with including the separate file.

'use strict';

angular.module('myApp', ['ngRoute']).
    config(['$routeProvider', function($routeProvider) {
$routeProvider.otherwise({redirectTo: '/home'});
}]);

This might get you started.

I always fall back on this solution. Not too hack-ish and gets the job done.

EDIT: I should point out that you might achieve the effect you want with the following code (forgive the inline styles; they should be in a separate sheet). It seems that the default alignment on an image (baseline) will cause the text to align to the baseline; setting that to middle gets things to render nicely, at least in FireFox 3.

<div>_x000D_
    <img src="https://cdn.sstatic.net/Sites/stackoverflow/company/img/logos/so/so-icon.svg" style="vertical-align: middle;" width="100px"/>_x000D_
    <span style="vertical-align: middle;">Here is some text.</span>_x000D_
</div>

Query would be like this:

SELECT ID, AccountID, Quantity, 
       SUM(Quantity) OVER (PARTITION BY AccountID ) AS TopBorcT 

       FROM #Empl ORDER BY AccountID

Partition by works like group by. Here we are grouping by AccountID so sum would be corresponding to AccountID.

First first case, AccountID = 1 , then sum(quantity) = 10 + 5 + 2 => 17 & For AccountID = 2, then sum(Quantity) = 7+3 => 10

so result would appear like attached snapshot.

A simple solution "workaround" still is to create a class of virtual functions "interface" and inherit it in the caller class. Then pass it as a parameter "could be in the constructor" of the other class that you want to call your caller class back.

DEFINE Interface:

class CallBack 
{
   virtual callMeBack () {};
};

This is the class that you want to call you back:

class AnotherClass ()
{
     public void RegisterMe(CallBack *callback)
     {
         m_callback = callback;
     }

     public void DoSomething ()
     {
        // DO STUFF
        // .....
        // then call
        if (m_callback) m_callback->callMeBack();
     }
     private CallBack *m_callback = NULL;
};

And this is the class that will be called back.

class Caller : public CallBack
{
    void DoSomthing ()
    {
    }

    void callMeBack()
    {
       std::cout << "I got your message" << std::endl;
    }
};

The 'bug' is discussed here https://bugs.eclipse.org/bugs/show_bug.cgi?id=402983. A lot of discussion around 'multiple monitor' set-ups. I experienced the problem today(click in Eclipse (off-the-shelf ADT v22.3.0-887826) Package Explorer then click in java editor, and the "no more handles" error appears). It makes Eclipse unuseable.

Got me thinking that it is a monitor/graphics card problem on my win7 64bit PC, rather than a problem with Eclipse. I re-installed the graphics card (nVidia GTX480) and updated the drivers. Noticed multiple error dialog boxes(samsung monitor not found) relating to my monitor(in fact a single BX2440 monitor set-up) as i closed the system down for reboot. So, on re-boot I upgraded the monitor driver. Then booted again, and the problem has gone(at least for now).

BTW, I don't have Win 7 SP1 installed, so i don't think the 'full Windows update' solution discussed elsewhere on SO necessarily works for everyone.

$watch returns a deregistration function. Calling it would deregister the $watcher.

var listener = $scope.$watch("quartz", function () {});
// ...
listener(); // Would clear the watch

Simply copy this code and hope this works fine for you.

Calendar c = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("dd:MMMM:yyyy HH:mm:ss a");
String strDate = sdf.format(c.getTime());

Just call comboBox.updateUI() after doing comboBox.setSelectedItem or comboBox.setSelectedIndex or comboModel.setSelectedItem

Similar to above, using filter from dplyr:

filter(df, fct %in% vc)

Check out the built-in function encodeURIComponent(str) and encodeURI(str).
In your case, this should work:

var myOtherUrl = 
       "http://example.com/index.html?url=" + encodeURIComponent(myUrl);

If you don't want to add a new dependency just to do this (like HTMLEntities) and you're already using Hpricot, it can both escape and unescape for you. It handles much more than CGI:

Hpricot.uxs "foo bär"
=> "foo bär"

Since VB6 is very similar to VBA, I think I might have a solution which does not require this much code to ReDim a 2-dimensional array - using Transpose, if you are working in Excel.

The solution (Excel VBA):

Dim n, m As Integer
n = 2
m = 1
Dim arrCity() As Variant
ReDim arrCity(1 To n, 1 To m)

m = m + 1
ReDim Preserve arrCity(1 To n, 1 To m)
arrCity = Application.Transpose(arrCity)
n = n + 1
ReDim Preserve arrCity(1 To m, 1 To n)
arrCity = Application.Transpose(arrCity)

What is different from OP's question: the lower bound of arrCity array is not 0, but 1. This is in order to let Application.Transpose do it's job.

Note that Transpose is a method of the Excel Application object (which in actuality is a shortcut to Application.WorksheetFunction.Transpose). And in VBA, one must take care when using Transpose as it has two significant limitations: If the array has more than 65536 elements, it will fail. If ANY element's length exceed 256 characters, it will fail. If neither of these is an issue, then Transpose will nicely convert the rank of an array form 1D to 2D or vice-versa.

Unfortunately there is nothing like 'Transpose' build into VB6.

I think it works the other way

<#if object.attribute??>
   Do whatever you want....
</#if>

If object.attribute is NOT NULL, then the content will be printed.

scanf uses any whitespace as a delimiter, so if you just say scanf("%d", &var) it will skip any whitespace and then read an integer (digits up to the next non-digit) and nothing more.

Note that whitespace is any whitespace -- spaces, tabs, newlines, or carriage returns. Any of those are whitespace and any one or more of them will serve to delimit successive integers.

I have been using the following solution (with no positioning and no line height) since over a year, it works with IE 7 and 8 as well.

<style>
.outer {
    font-size: 0;
    width: 400px;
    height: 400px;
    background: orange;
    text-align: center;
    display: inline-block;
}

.outer .emptyDiv {
    height: 100%;
    background: orange;
    visibility: collapse;
}

.outer .inner {
    padding: 10px;
    background: red;
    font: bold 12px Arial;
}

.verticalCenter {
    display: inline-block;
    *display: inline;
    zoom: 1;
    vertical-align: middle;
}
</style>

<div class="outer">
    <div class="emptyDiv verticalCenter"></div>
    <div class="inner verticalCenter">
        <p>Line 1</p>
        <p>Line 2</p>
    </div>
</div>

ArrayIndexOutOfBoundsException in simple words is -> you have 10 students in your class (int array size 10) and you want to view the value of the 11th student (a student who does not exist)

if you make this int i[3] then i takes values i[0] i[1] i[2]

for your problem try this code structure

double[] array = new double[50];

    for (int i = 0; i < 24; i++) {

    }

    for (int j = 25; j < 50; j++) {

    }

    rgb = rgb.match(/^rgba?\((\d+),\s*(\d+),\s*(\d+)(?:,\s*(\d+))?\)$/);
    hex = (x)->

upgrading to nodejs v0.12.7

Base on @tbranyen's solution, I create an index.js file that load arbitrary javascripts under current folder as part of the exports.

// Load `*.js` under current directory as properties
//  i.e., `User.js` will become `exports['User']` or `exports.User`
require('fs').readdirSync(__dirname + '/').forEach(function(file) {
  if (file.match(/\.js$/) !== null && file !== 'index.js') {
    var name = file.replace('.js', '');
    exports[name] = require('./' + file);
  }
});

Then you can require this directory from any where else.

All answers above contribute important info on the original question. However, there is a generalization that seems wrong.

It is possible to set width and height to at least one inline element (that I can think of) – the <img> element.

Both accepted answers here and on this duplicate state that this is not possible but this doesn’t seem like a valid general rule.

Example:

img {_x000D_
  width: 200px;_x000D_
  height: 200px;_x000D_
  border: 1px solid red;_x000D_
}

<img src="#" />

The img has display: inline, but its width and height were successfully set.

the first two use lambda, the third uses regular code... hope you find it helpful

            //Trust all certificates
            System.Net.ServicePointManager.ServerCertificateValidationCallback =

            // trust sender
            System.Net.ServicePointManager.ServerCertificateValidationCallback
                = ((sender, cert, chain, errors) => cert.Subject.Contains("YourServerName"));

            // validate cert by calling a function
            ServicePointManager.ServerCertificateValidationCallback += new RemoteCertificateValidationCallback(ValidateRemoteCertificate);

    // callback used to validate the certificate in an SSL conversation
    private static bool ValidateRemoteCertificate(object sender, X509Certificate cert, X509Chain chain, SslPolicyErrors policyErrors)
    {
        bool result = false;
        if (cert.Subject.ToUpper().Contains("YourServerName"))
        {
            result = true;
        }

        return result;
    }

In addition to @Bergi’s answer, I’d like to offer a third alternative. It's very similar to @Bergi’s 2nd example, but instead of awaiting each readFile individually, you create an array of promises, each which you await at the end.

import fs from 'fs-promise';
async function printFiles () {
  const files = await getFilePaths();

  const promises = files.map((file) => fs.readFile(file, 'utf8'))

  const contents = await Promise.all(promises)

  contents.forEach(console.log);
}

Note that the function passed to .map() does not need to be async, since fs.readFile returns a Promise object anyway. Therefore promises is an array of Promise objects, which can be sent to Promise.all().

In @Bergi’s answer, the console may log file contents in the order they’re read. For example if a really small file finishes reading before a really large file, it will be logged first, even if the small file comes after the large file in the files array. However, in my method above, you are guaranteed the console will log the files in the same order as the provided array.

Build URL '/search' as string. Like

"/search?fname="+fname"+"&lname="+lname

Actually I didn't use

 `$http({method:'GET', url:'/search', params:{fname: fname, lname: lname}})` 

but I'm sure "params" should be JSON.stringify like for POST

var jsonData = JSON.stringify(
    {
        fname: fname,
        lname: lname 
    }
);

After:

$http({
  method:'GET',
  url:'/search',
  params: jsonData
});

OP wanted two specific maps, but if you'd like to have a dynamic number of maps on one page (for instance a list of retailer locations) you need to go another route. The standard implementation of Google maps API defines the map as a global variable, this won't work with a dynamic number of maps. Here's my code to solve this without global variables:

function mapAddress(mapElement, address) {
var geocoder = new google.maps.Geocoder();

geocoder.geocode({ 'address': address }, function (results, status) {
    if (status == google.maps.GeocoderStatus.OK) {
        var mapOptions = {
            zoom: 14,
            center: results[0].geometry.location,
            disableDefaultUI: true
        };
        var map = new google.maps.Map(document.getElementById(mapElement), mapOptions);
        var marker = new google.maps.Marker({
            map: map,
            position: results[0].geometry.location
        });
    } else {
        alert("Geocode was not successful for the following reason: " + status);
    }
});
}

Just pass the ID and address of each map to the function to plot the map and mark the address.

Using redis-cli, you can stop it trying to save the snapshot:

config set stop-writes-on-bgsave-error no

This is a quick workaround, but if you care about the data you are using it for, you should check to make sure why bgsave failed in first place.

I found useful npm package https://www.npmjs.com/package/element-resize-detector

An optimized cross-browser resize listener for elements.

Can use it with React component or functional component(Specially useful for react hooks)

I was looking to find the answer to this question too, but the accepted answer was breaking for me. Apparently using window.innerWidth isn't portable. It does work in some browsers, but I noticed Firefox didn't like it.

Gregg Tavares posted a great resource here that addresses this issue directly: http://webglfundamentals.org/webgl/lessons/webgl-anti-patterns.html (See anti-pattern #'s 3 and 4).

Using canvas.clientWidth instead of window.innerWidth seems to work nicely.

Here's Gregg's suggested render loop:

function resize() {
  var width = gl.canvas.clientWidth;
  var height = gl.canvas.clientHeight;
  if (gl.canvas.width != width ||
      gl.canvas.height != height) {
     gl.canvas.width = width;
     gl.canvas.height = height;
     return true;
  }
  return false;
}

var needToRender = true;  // draw at least once
function checkRender() {
   if (resize() || needToRender) {
     needToRender = false;
     drawStuff();
   }
   requestAnimationFrame(checkRender);
}
checkRender();

In cordova 6.2.0

cd cordova/ #change to root cordova folder
platforms/android/cordova/clean #clean if you want
cordova build android --release -- --keystore="/path/to/keystore" --storePassword=password --alias=alias_name #password will be prompted if you have any

Previous answer:

According to cordova 5.0.0

{
     "android": {
         "release": {
             "keystore": "app-release-key.keystore",
             "alias": "alias_name"
         }
     }
 }

and run ./build --release --buildConfig build.json from directory platforms/android/cordova/

keystore file location is relative to platforms/android/cordova/, so in above configuration .keystore file and build.json are in same directory.

keytool -genkey -v -keystore app-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000

@coldmind answer is correct but lacks details.

The 'NOT NULL constraint failed' occurs when something tries to set None to the 'zipcode' property, while it has not been explicitely allowed.

It usually happens when:

1) your field has Null=False by default, so that the value in the database cannot be None (i.e. undefined) when the object is created and saved in the database (this happens after a objects_set.create() call or setting the .zipcode property and doing a .save() call).

For instance, if somewhere in your code an assignement results in:

model.zipcode = None

this error is raised

2) When creating or updating the database, Django is constrained to find a default value to fill the field, because Null=False by default. It does not find any because you haven't defined any. So this error can not only happen during code execution but also when creating the database?

3) Note that the same error would be returned of you define default=None, or if your default value with an incorrect type, for instance default='00000' instead of 00000 for your field (maybe can there be automatic conversion between char and integers, but I would advise against relying on it. Besides, explicit is better than implicit). Most likely an error would also be raised if the default value violates the max_length property, e.g. 123456

So you'll have to define the field by one of the following:

models.IntegerField(_('zipcode'), max_length=5, Null=True,
   blank=True)

models.IntegerField(_('zipcode'), max_length=5, Null=False,
   blank=True, default=00000)

models.IntegerField(_('zipcode'), max_length=5, blank=True,
   default=00000)

and then make a migration (python3 manage.py makemigration ) and then migrate (python3 manage.py migrate).

For safety you can also delete the last failed migration files in <app_name>/migrations/, there are usually named after this pattern:

<NUMBER>_auto_<DATE>_<HOUR>.py

Finally, if you don't set Null=True, make sure that mode.zipcode = None is never done anywhere.

I've always come back here for the answer so I wanted to make a short simple one to go to.

There are multiple ways of doing this:

1. Using WPF Tools. Easiest.

Add Namespaces:

• System.Windows.Interactivitiy
• Microsoft.Expression.Interactions

XAML:

Use the EventName to call the event you want then specify your Method name in the MethodName.

<Window>
    xmlns:wi="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
    xmlns:ei="http://schemas.microsoft.com/expression/2010/interactions">

    <wi:Interaction.Triggers>
        <wi:EventTrigger EventName="SelectionChanged">
            <ei:CallMethodAction
                TargetObject="{Binding}"
                MethodName="ShowCustomer"/>
        </wi:EventTrigger>
    </wi:Interaction.Triggers>
</Window>

Code:

public void ShowCustomer()
{
    // Do something.
}

2. Using MVVMLight. Most difficult.

Install GalaSoft NuGet package.

Get the namespaces:

• System.Windows.Interactivity
• GalaSoft.MvvmLight.Platform

XAML:

Use the EventName to call the event you want then specify your Command name in your binding. If you want to pass the arguments of the method, mark PassEventArgsToCommand to true.

<Window>
    xmlns:wi="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
    xmlns:cmd="http://www.galasoft.ch/mvvmlight">

    <wi:Interaction.Triggers>
       <wi:EventTrigger EventName="Navigated">
           <cmd:EventToCommand Command="{Binding CommandNameHere}"
               PassEventArgsToCommand="True" />
       </wi:EventTrigger>
    </wi:Interaction.Triggers>
</Window>

Code Implementing Delegates: Source

You must get the Prism MVVM NuGet package for this.

using Microsoft.Practices.Prism.Commands;

// With params.
public DelegateCommand<string> CommandOne { get; set; }
// Without params.
public DelegateCommand CommandTwo { get; set; }

public MainWindow()

    // Do something here.
}

private void executeCommandTwo()

}

Code Without DelegateCommand: Source

using GalaSoft.MvvmLight.CommandWpf

public MainWindow()

    CommandOne = new RelayCommand<string>(executeCommandOne);
    CommandTwo = new RelayCommand(executeCommandTwo);

3. Using Telerik EventToCommandBehavior. It's an option.

You'll have to download it's NuGet Package.

XAML:

<i:Interaction.Behaviors>
    <telerek:EventToCommandBehavior
         Command="{Binding DropCommand}"
         Event="Drop"
         PassArguments="True" />
</i:Interaction.Behaviors>

Code:

public ActionCommand<DragEventArgs> DropCommand { get; private set; }

this.DropCommand = new ActionCommand<DragEventArgs>(OnDrop);

private void OnDrop(DragEventArgs e)
{
    // Do Something
}

when you perform y=x() you are actually assigning y to the result of calling the function object x and the function has a return value of None. Function calls in python are performed using (). To assign x to y so you can call y just like you would x you assign the function object x to y like y=x and call the function using y()

The error is because fName is included in the SELECT list, but is not included in a GROUP BY clause and is not part of an aggregate function (Count(), Min(), Max(), Sum(), etc.)

You can fix that problem by including fName in a GROUP BY. But then you will face the same issue with surname. So put both in the GROUP BY:

SELECT
    fName,
    surname,
    Count(*) AS num_rows
FROM
    author
    INNER JOIN book
    ON author.aID = book.authorID;
GROUP BY
    fName,
    surname

Note I used Count(*) where you wanted SUM(orders.quantity). However, orders isn't included in the FROM section of your query, so you must include it before you can Sum() one of its fields.

If you have Access available, build the query in the query designer. It can help you understand what features are possible and apply the correct Access SQL syntax.

Use yepnope.js or Modernizr (which includes yepnope.js as Modernizr.load).

UPDATE

Just to follow up, here's a good equivalent of what you currently have using yepnope, showing dependencies on multiple scripts:

yepnope({
  load: ['script1.js', 'script2.js', 'script3.js'],
  complete: function () {
      // all the scripts have loaded, do whatever you want here
  }
});

There are two parts you need:

• android:versionCode
• android:versionName

versionCode is a number, and every version of the app you submit to the market needs to have a higher number than the last.

VersionName is a string and can be anything you want it to be. This is where you define your app as "1.0" or "2.5" or "2 Alpha EXTREME!" or whatever.

Example:

Kotlin:

val manager = this.packageManager
val info = manager.getPackageInfo(this.packageName, PackageManager.GET_ACTIVITIES)
toast("PackageName = " + info.packageName + "\nVersionCode = "
            + info.versionCode + "\nVersionName = "
            + info.versionName + "\nPermissions = " + info.permissions)

Java:

PackageManager manager = this.getPackageManager();
PackageInfo info = manager.getPackageInfo(this.getPackageName(), PackageManager.GET_ACTIVITIES);
Toast.makeText(this,
     "PackageName = " + info.packageName + "\nVersionCode = "
       + info.versionCode + "\nVersionName = "
       + info.versionName + "\nPermissions = " + info.permissions, Toast.LENGTH_SHORT).show();

String characters are runes, so to print them, you have to turn them back into String.

fmt.Print(string("HELLO"[1]))

Use this below code

 border:2px soild #eee;

 margin: 15px 15px;
 -webkit-box-shadow: 2px 3px 8px #eee;
-moz-box-shadow: 2px 3px 8px #eee;
box-shadow: 2px 3px 8px #eee;

Explanation:-

box-shadow requires you to set the horizontal & vertical offsets, you can then optionally set the blur and colour, you can also choose to have the shadow inset instead of the default outset. Colour can be defined as hex or rgba.

box-shadow : inset/outset h-offset v-offset blur spread color;

Explanation of the values...

inset/outset -- whether the shadow is inside or outside the box. If not specified it will default to outset.

h-offset -- the horizontal offset of the shadow (required value)

v-offset -- the vertical offset of the shadow (required value)

blur -- as it says, the blur of the shadow

spread -- moves the shadow away from the box equally on all sides. A positive value causes the shadow to expand, negative causes it to contract. Though this value isn't often used, it is useful with multiple shadows.

color -- as it says, the color of the shadow

Usage

box-shadow:2px 3px 8px #eee; a gray shadow with a horizontal outset of 2px, vertical of 3px and a blur of 8px

It works in user-style, and it seems not to work in web pages. I have not found official direction from Mozilla on this. While it may have worked at some point, Firefox does not have official support for this. This bug is still open https://bugzilla.mozilla.org/show_bug.cgi?id=77790

I had this error. Nothing worked for me until I opened the SQLServer log file in the "MSSQL10_50" Log folder. That clearly stated which file could not be overwritten. It turned out that the .mdf file was being written into the "MSSQL10" data folder. I made sure that folder had the same SQLServer user permissions as the "MSSQL10_50" equivalent folder. Then it all worked.

The issue here is that the error detail is logged but not reported, so check the logs.

your Apple developer certificate might have expired or else ur system date is greater than your account expiry date

Use itoa, as is shown here.

char buf[5];
// Convert 123 to string [buf]
itoa(123, buf, 10);

buf will be a string array as you documented. You might need to increase the size of the buffer.

In your custom array adapter, you override the getView() method, as you presumably familiar with. Then all you have to do is use a switch statement or an if statement to return a certain custom View depending on the position argument passed to the getView method. Android is clever in that it will only give you a convertView of the appropriate type for your position/row; you do not need to check it is of the correct type. You can help Android with this by overriding the getItemViewType() and getViewTypeCount() methods appropriately.

I got this to work:

>>> import locale
>>> locale.setlocale(locale.LC_ALL, 'en_US')
'en_US'
>>> locale.format("%d", 1255000, grouping=True)
'1,255,000'

Sure, you don't need internationalization support, but it's clear, concise, and uses a built-in library.

P.S. That "%d" is the usual %-style formatter. You can have only one formatter, but it can be whatever you need in terms of field width and precision settings.

P.P.S. If you can't get locale to work, I'd suggest a modified version of Mark's answer:

def intWithCommas(x):
    if type(x) not in [type(0), type(0L)]:
        raise TypeError("Parameter must be an integer.")
    if x < 0:
        return '-' + intWithCommas(-x)
    result = ''
    while x >= 1000:
        x, r = divmod(x, 1000)
        result = ",%03d%s" % (r, result)
    return "%d%s" % (x, result)

Recursion is useful for the negative case, but one recursion per comma seems a bit excessive to me.

<input type="checkbox" name="check_list[<? echo $row['Report ID'] ?>]" value="<? echo $row['Report ID'] ?>">

And after the post, you can loop through them:

   if(!empty($_POST['check_list'])){
     foreach($_POST['check_list'] as $report_id){
        echo "$report_id was checked! ";
     }
   }

Or get a certain value posted from previous page:

if(isset($_POST['check_list'][$report_id])){
  echo $report_id . " was checked!<br/>";
}

The best place to understand the difference is at the official documentation on values / values_list. It has many useful examples and explains it very clearly. The django docs are very user freindly.

Here's a short snippet to keep SO reviewers happy:

values

Returns a QuerySet that returns dictionaries, rather than model instances, when used as an iterable.

And read the section which follows it:

value_list

This is similar to values() except that instead of returning dictionaries, it returns tuples when iterated over.

You can remove the warning by adding the below code in <intent-filter> inside <activity>

<action android:name="android.intent.action.VIEW" />

https://github.com/JamesHeinrich/getID3 download getid3 zip and than only getid3 named folder copy paste in project folder and use it as below show...

        $fileinfo = $getID3->analyze($filename);

        $width=$fileinfo['video']['resolution_x'];
        $height=$fileinfo['video']['resolution_y'];

I believe this is quite language specific and for the C++ case a minor point for enum class type. Which appears more safe than traditional C enum. BUT

If you look at the implementation of std::byte its something like:

enum class byte : unsigned char {} ;

Source: https://en.cppreference.com/w/cpp/language/enum

And also consider this:

Otherwise, if T is a enumeration type that is either scoped or unscoped with fixed underlying type, and if the braced-init-list has only one initializer, and if the conversion from the initializer to the underlying type is non-narrowing, and if the initialization is direct-list-initialization, then the enumeration is initialized with the result of converting the initializer to its underlying type.

(since C++17)

Source: https://en.cppreference.com/w/cpp/language/list_initialization

This is an example of enum class representing values that are not defined enumerator. For this reason you cannot place complete trust in enums. Depending on application this might be important.

However, I really like what @Harlan Kassler said in his post and will start using that strategy in some situations myself.

Just an example of unsafe enum class:

enum class Numbers : unsigned
{
    One = 1u,
    Two = 2u
};

int main()
{
    Numbers zero{ 0u };
    return 0;
}

For Lollipop and above. create a drawable

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="false">
        <shape android:shape="line">
            <stroke android:width="1dp"
                android:color="@color/onePlusRed" />
        </shape>
    </item>
</selector>

and use it as foreground.
android:foreground="@drawable/strike_through"

If you want to just "set" the actual filename, without incurring the overhead of loading and re-saving the file (!!), or resorting to using a charfield (!!!), you might want to try something like this --

model_instance.myfile = model_instance.myfile.field.attr_class(model_instance, model_instance.myfile.field, 'my-filename.jpg')

This will light up your model_instance.myfile.url and all the rest of them just as if you'd actually uploaded the file.

Like @t-stone says, what we really want, is to be able to set instance.myfile.path = 'my-filename.jpg', but Django doesn't currently support that.

This worked for me:

Maybe a better question would be to ask why do these operators exist in C. K&R calls increment and decrement operators 'unusual' (Section 2.8page 46). The Introduction calls them 'more concise and often more efficient'. I suspect that the fact that these operations always come up in pointer manipulation also has played a part in their introduction. In Python it has been probably decided that it made no sense to try to optimise increments (in fact I just did a test in C, and it seems that the gcc-generated assembly uses addl instead of incl in both cases) and there is no pointer arithmetic; so it would have been just One More Way to Do It and we know Python loathes that.

Ideally, a hashtable is O(1). The problem is if two keys are not equal, however they result in the same hash.

For example, imagine the strings "it was the best of times it was the worst of times" and "Green Eggs and Ham" both resulted in a hash value of 123.

When the first string is inserted, it's put in bucket 123. When the second string is inserted, it would see that a value already exists for bucket 123. It would then compare the new value to the existing value, and see they are not equal. In this case, an array or linked list is created for that key. At this point, retrieving this value becomes O(n) as the hashtable needs to iterate through each value in that bucket to find the desired one.

For this reason, when using a hash table, it's important to use a key with a really good hash function that's both fast and doesn't often result in duplicate values for different objects.

Make sense?

jvmArgumentEnforcer.forceArgument();

This will give you one last document for a collection

db.collectionName.findOne({}, {sort:{$natural:-1}})

$natural:-1 means order opposite of the one that records are inserted in.

Edit: For all the downvoters, above is a Mongoose syntax, mongo CLI syntax is: db.collectionName.find({}).sort({$natural:-1}).limit(1)

As pointed out by others, define studentType outside the function. One more thing, even if you do that, do not create a local studentType instance inside the function. The instance is on the function stack and will not be available when you try to return it. One thing you can however do is create studentType dynamically and return the pointer to it outside the function.

Maybe this helps:

a = [{ 'main_color': 'red', 'second_color':'blue'},
     { 'main_color': 'yellow', 'second_color':'green'},
     { 'main_color': 'yellow', 'second_color':'blue'}]

def in_dictlist((key, value), my_dictlist):
    for this in my_dictlist:
        if this[key] == value:
            return this
    return {}

print in_dictlist(('main_color','red'), a)
print in_dictlist(('main_color','pink'), a)

There are a few ways to use log4net. I found it is useful while I was searching for a solution. The solution is described here: https://www.hemelix.com/log4net/

Try this tutorial it has the explanation and it will be helpful http://www.ccs.neu.edu/home/kathleen/classes/cs3200/JDBCtutorial.pdf

You can also use mapState in your vue component to direct getting state from store.

In your component:

computed: mapState([
  'my_state'
])

Where my_state is a variable from the store.

Country Data NPM Package.

If you're using node or NPM in general, you should take a look at the thorough Country Data package.

Since you're trying to get the Country from a phone number, you face two major obstacles:

1. Parsing the phone number to get the Country code.

2. Handling situations where a Country code can belong to more than one Country. e.g. Country Code of "+1" belongs to the United States and Canada.

However, the Country Data package will allow you to do something like this:

var CountryDataLookup = require('country-data').lookup;

lookup.countries({countryCallingCodes: '+1'})

And these are the returning objects:

[ { alpha2: 'CA',
    alpha3: 'CAN',
    countryCallingCodes: [ '+1' ],
    currencies: [ 'CAD' ],
    ioc: 'CAN',
    languages: [ 'eng', 'fra' ],
    name: 'Canada',
    status: 'assigned' },
  { alpha2: 'UM',
    alpha3: 'UMI',
    countryCallingCodes: [ '+1' ],
    currencies: [ 'USD' ],
    ioc: '',
    languages: [ 'eng' ],
    name: 'United States Minor Outlying Islands',
    status: 'assigned' },
  { alpha2: 'US',
    alpha3: 'USA',
    countryCallingCodes: [ '+1' ],
    currencies: [ 'USD' ],
    ioc: 'USA',
    languages: [ 'eng' ],
    name: 'United States',
    status: 'assigned' } ]

I add credentials for HttpWebRequest.

myReq.UseDefaultCredentials = true;
myReq.PreAuthenticate = true;
myReq.Credentials = CredentialCache.DefaultCredentials;

I think you are looking for:

window.location = 'http://someUrl.com';

It's not jQuery; it's pure JavaScript.

Rom, you're doing it wrong. You don't want to write files to disk so that IIS can serve them up. That adds security implications as well as increases complexity. All you really need to do is save the CSV directly to the response stream.

Here's the scenario: User wishes to download csv. User submits a form with details about the csv they want. You prepare the csv, then provide the user a URL to an aspx page which can be used to construct the csv file and write it to the response stream. The user clicks the link. The aspx page is blank; in the page codebehind you simply write the csv to the response stream and end it.

You can add the following to the (I believe this is correct) Load event:

string attachment = "attachment; filename=MyCsvLol.csv";
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.ClearHeaders();
HttpContext.Current.Response.ClearContent();
HttpContext.Current.Response.AddHeader("content-disposition", attachment);
HttpContext.Current.Response.ContentType = "text/csv";
HttpContext.Current.Response.AddHeader("Pragma", "public");

var sb = new StringBuilder();
foreach(var line in DataToExportToCSV)
  sb.AppendLine(TransformDataLineIntoCsv(line));

HttpContext.Current.Response.Write(sb.ToString());

writing to the response stream code ganked from here.

Starting with AspNetCore 2.0, it's recommended to use ContentResult instead of the Produce attribute in this case. See: https://github.com/aspnet/Mvc/issues/6657#issuecomment-322586885

This doesn't rely on serialization nor on content negotiation.

[HttpGet]
public ContentResult Index() {
    return new ContentResult {
        ContentType = "text/html",
        StatusCode = (int)HttpStatusCode.OK,
        Content = "<html><body>Hello World</body></html>"
    };
}

Just put this code in your content div

<?php
// TO SHOW THE PAGE CONTENTS
    while ( have_posts() ) : the_post(); ?> <!--Because the_content() works only inside a WP Loop -->
        <div class="entry-content-page">
            <?php the_content(); ?> <!-- Page Content -->
        </div><!-- .entry-content-page -->

    <?php
endwhile; //resetting the page loop
wp_reset_query(); //resetting the page query
?>

If your working directory points to the trunk, then you should be able to merge your branch with:

svn merge https://HOST/repository/branches/branch_1

be sure to be to issue this command in the root directory of your trunk

public String decodeString(String URL)
    {

    String urlString="";
    try {
        urlString = URLDecoder.decode(URL,"UTF-8");
        } catch (UnsupportedEncodingException e) {
            // TODO Auto-generated catch block

        }

        return urlString;

    }

The .pyc file is Python that has already been compiled to byte-code. Python automatically runs a .pyc file if it finds one with the same name as a .py file you invoke.

"An Introduction to Python" says this about compiled Python files:

A program doesn't run any faster when it is read from a ‘.pyc’ or ‘.pyo’ file than when it is read from a ‘.py’ file; the only thing that's faster about ‘.pyc’ or ‘.pyo’ files is the speed with which they are loaded.

The advantage of running a .pyc file is that Python doesn't have to incur the overhead of compiling it before running it. Since Python would compile to byte-code before running a .py file anyway, there shouldn't be any performance improvement aside from that.

How much improvement can you get from using compiled .pyc files? That depends on what the script does. For a very brief script that simply prints "Hello World," compiling could constitute a large percentage of the total startup-and-run time. But the cost of compiling a script relative to the total run time diminishes for longer-running scripts.

The script you name on the command-line is never saved to a .pyc file. Only modules loaded by that "main" script are saved in that way.

I struggled for a couple of days to find anything that would work for me as was passing multiple arrays of ids and returning a blob. Turns out if using .NET CORE I'm using 2.1, you need to use [FromBody] and as can only use once you need to create a viewmodel to hold the data.

Wrap up content like below,

var params = {
            "IDs": IDs,
            "ID2s": IDs2,
            "id": 1
        };

In my case I had already json'd the arrays and passed the result to the function

var IDs = JsonConvert.SerializeObject(Model.Select(s => s.ID).ToArray());

Then call the XMLHttpRequest POST and stringify the object

var ajax = new XMLHttpRequest();
ajax.open("POST", '@Url.Action("MyAction", "MyController")', true);
ajax.responseType = "blob";
ajax.setRequestHeader("Content-Type", "application/json;charset=UTF-8");           
ajax.onreadystatechange = function () {
    if (this.readyState == 4) {
       var blob = new Blob([this.response], { type: "application/octet-stream" });
       saveAs(blob, "filename.zip");
    }
};

ajax.send(JSON.stringify(params));

Then have a model like this

public class MyModel
{
    public int[] IDs { get; set; }
    public int[] ID2s { get; set; }
    public int id { get; set; }
}

Then pass in Action like

public async Task<IActionResult> MyAction([FromBody] MyModel model)

Use this add-on if your returning a file

<script src="https://cdnjs.cloudflare.com/ajax/libs/FileSaver.js/1.3.3/FileSaver.min.js"></script>

You just need to wrap object in ()

var arr = [{_x000D_
  id: 1,_x000D_
  name: 'bill'_x000D_
}, {_x000D_
  id: 2,_x000D_
  name: 'ted'_x000D_
}]_x000D_
_x000D_
var result = arr.map(person => ({ value: person.id, text: person.name }));_x000D_
console.log(result)

I had the same issue, and it turned out to be due to permission of the catalina.out file not being correct. It was not writable by the tomcat user. Once I fixed the permissions, the issue got resolved. I got to know that it is a permissions issue from the logs in the tomcat8-initd.log file:

/usr/sbin/tomcat8: line 40: /usr/share/tomcat8/logs/catalina.out: Permission denied

If it helps anyone, I found that the problem was I already had an android:onClick event in my layout file (which I inflated for the ListView rows). This was superseding the onItemClick event.

Given @DougW response, what I do to manage version is simpler, I add to my checkbox view:

android:paddingLeft="@dimen/padding_checkbox"

where the dimen is found in two values folders:

values

<resources>

    <dimen name="padding_checkbox">0dp</dimen>

</resources>

values-v17 (4.2 JellyBean)

<resources>

    <dimen name="padding_checkbox">10dp</dimen>

</resources>

I have a custom check, use the dps to your best choice.

void means it returns nothing. It does not return a string, you write a string to System.out but you're not returning one.

You must specify what a method returns, even if you're just saying that it returns nothing.

Technically speaking they could have designed the language such that if you don't write a return type then it's assumed to return nothing, however making you explicitly write out void helps to ensure that the lack of a returned value is intentional and not accidental.

To set a background image without shrinking after adding the child, use this code.

  body: Container(
    constraints: BoxConstraints.expand(),
      decoration: BoxDecoration(
        image: DecorationImage(
            image: AssetImage("assets/aaa.jpg"),
        fit: BoxFit.cover,
        )
      ),

    //You can use any widget
    child: Column(
      children: <Widget>[],
    ),
    ),
