Alternatively, you can directly use javascript's window.onresize

As example, my code (using scriptaculos) is :

window.onresize = function (){
    var w = $("form").getWidth() + "px";
    $('gfx').setStyle( { width : w } );
}

Where form is an html form on my webpage and gfx the highchart graphics.

Ricardo's answer is correct, however: sometimes you may find yourself in a situation where the container simply doesn't resize as desired as the browser window changes size, thus not allowing highcharts to resize itself.

This always works:

1. Set up a timed and pipelined resize event listener. Example with 500ms on jsFiddle
2. use chart.setSize(width, height, doAnimation = true); in your actual resize function to set the height and width dynamically
3. Set reflow: false in the highcharts-options and of course set height and width explicitly on creation. As we'll be doing our own resize event handling there's no need Highcharts hooks in another one.

It's said here that you should be able to add the following to your chart config:

  credits: {
    enabled: false
  },

that will remove the "Highcharts.com" text from the bottom of the chart.

@RobinL as mentioned in previous comments, you can use chart.series[n].setData(). First you need to make sure you’ve assigned a chart instance to the chart variable, that way it adopts all the properties and methods you need to access and manipulate the chart.

I’ve also used the second parameter of setData() and had it false, to prevent automatic rendering of the chart. This was because I have multiple data series, so I’ll rather update each of them, with render=false, and then running chart.redraw(). This multiplied performance (I’m having 10,000-100,000 data points and refreshing the data set every 50 milliseconds).

If you are using push to push the data to the option.series dynamically .. just use

options.series = [];  

to clear it.

options.series = [];
$("#change").click(function(){
}

Highcharts will automatically try to find the best format for the current zoom-range. This is done if the xAxis has the type 'datetime'. Next the unit of the current zoom is calculated, it could be one of:

• second
• minute
• hour
• day
• week
• month
• year

This unit is then used find a format for the axis labels. The default patterns are:

second: '%H:%M:%S',
minute: '%H:%M',
hour: '%H:%M',
day: '%e. %b',
week: '%e. %b',
month: '%b \'%y',
year: '%Y'

If you want the day to be part of the "hour"-level labels you should change the dateTimeLabelFormats option for that level include %d or %e. These are the available patters:

• %a: Short weekday, like 'Mon'.
• %A: Long weekday, like 'Monday'.
• %d: Two digit day of the month, 01 to 31.
• %e: Day of the month, 1 through 31.
• %b: Short month, like 'Jan'.
• %B: Long month, like 'January'.
• %m: Two digit month number, 01 through 12.
• %y: Two digits year, like 09 for 2009.
• %Y: Four digits year, like 2009.
• %H: Two digits hours in 24h format, 00 through 23.
• %I: Two digits hours in 12h format, 00 through 11.
• %l (Lower case L): Hours in 12h format, 1 through 11.
• %M: Two digits minutes, 00 through 59.
• %p: Upper case AM or PM.
• %P: Lower case AM or PM.
• %S: Two digits seconds, 00 through 59

Looks like HighChart 2.2.0 has resolved this issue. I tried it here with the same code you have, and the first series is hidden now. Could you try it with HighChart 2.2.0?

Try this:

yAxis: {min: 0, max: 100}

See this jsfiddle example

For the yAxis you'll also need:

gridLineColor: 'transparent',

This worked for me. Its tedious to set all the colour options for a series, especially if it's dynamic

plotOptions: {
  column: {
   colorByPoint: true
  }
}

if you don't want recursion you could try:

x = [u'sam', [['Test', [['one', [], []]], [(u'file.txt', ['id', 1, 0])]], ['Test2', [], [(u'file2.txt', ['id', 1, 2])]]], []]
layer1=x
layer2=[]
while True:
    for i in layer1:
        if isinstance(i,list):
            for j in i:
                layer2.append(j)
        else:
            print i
    layer1[:]=layer2
    layer2=[]
    if len(layer1)==0:
        break

which gives:

sam
Test
Test2
(u'file.txt', ['id', 1, 0])
(u'file2.txt', ['id', 1, 2])
one

(note that it didn't look into the tuples for lists because the tuples aren't lists. You can add tuple to the "isinstance" method if you want to fix this)

My answer addresses EF core. I reference this github issue, and the docs on configuring DbContext:

Simple

Override the OnConfiguring method of your DbContext class (YourCustomDbContext) as shown here to use a ConsoleLoggerProvider; your queries should log to the console:

public class YourCustomDbContext : DbContext
{
    #region DefineLoggerFactory
    public static readonly LoggerFactory MyLoggerFactory
        = new LoggerFactory(new[] {new ConsoleLoggerProvider((_, __) => true, true)});
    #endregion


    #region RegisterLoggerFactory
    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
        => optionsBuilder
            .UseLoggerFactory(MyLoggerFactory); // Warning: Do not create a new ILoggerFactory instance each time                
    #endregion
}

Complex

This Complex case avoids overriding the DbContext OnConfiguring method. , which is discouraged in the docs: "This approach does not lend itself to testing, unless the tests target the full database."

This Complex case uses:

• The IServiceCollection in Startup class ConfigureServices method (instead of overriding the OnConfiguring method; the benefit is a looser coupling between the DbContext and the ILoggerProvider you want to use)
• An implementation of ILoggerProvider (instead of using the ConsoleLoggerProvider implementation shown above; benefit is our implementation shows how we would log to File (I don't see a File Logging Provider shipped with EF Core))

Like this:

public class Startup

    public void ConfigureServices(IServiceCollection services)
    {
        ...
        var lf = new LoggerFactory();
        lf.AddProvider(new MyLoggerProvider());

        services.AddDbContext<YOUR_DB_CONTEXT>(optionsBuilder => optionsBuilder
                .UseSqlServer(connection_string)
                //Using the LoggerFactory 
                .UseLoggerFactory(lf));
        ...
    }
}

Here's the implementation of a MyLoggerProvider (and its MyLogger which appends its logs to a File you can configure; your EF Core queries will appear in the file.)

public class MyLoggerProvider : ILoggerProvider
{
    public ILogger CreateLogger(string categoryName)
    {
        return new MyLogger();
    }

    public void Dispose()
    { }

    private class MyLogger : ILogger
    {
        public bool IsEnabled(LogLevel logLevel)
        {
            return true;
        }

        public void Log<TState>(LogLevel logLevel, EventId eventId, TState state, Exception exception, Func<TState, Exception, string> formatter)
        {
            File.AppendAllText(@"C:\temp\log.txt", formatter(state, exception));
            Console.WriteLine(formatter(state, exception));
        }

        public IDisposable BeginScope<TState>(TState state)
        {
            return null;
        }
    } 
}

<script type="text/javascript">
      $(document).ready(function() {
                showWarning('@ViewBag.Message');
      });

</script>

You can use ViewBag.PropertyName in javascript like this.

Another difference is when async function returns just Task instead of Task<T> then you cannot use

GetFooAsync(...).Result;

Whereas

GetFooAsync(...).GetAwaiter().GetResult();

still works.

I know the example code in the question is for the case Task<T>, however the question is asked generally.

I will say no.

But the only proof that I have is personal experience and the fact that documentation on line continuation doesn't have anything else in it.

http://msdn.microsoft.com/en-us/library/aa711641(VS.71).aspx

The return type must be the same as, or a subtype of, the return type declared in the original overridden method in the superclass.

-L is the test for file exists and is also a symbolic link

If you do not want to test for the file being a symbolic link, but just test to see if it exists regardless of type (file, directory, socket etc) then use -e

So if file is really file and not just a symbolic link you can do all these tests and get an exit status whose value indicates the error condition.

if [ ! \( -e "${file}" \) ]
then
     echo "%ERROR: file ${file} does not exist!" >&2
     exit 1
elif [ ! \( -f "${file}" \) ]
then
     echo "%ERROR: ${file} is not a file!" >&2
     exit 2
elif [ ! \( -r "${file}" \) ]
then
     echo "%ERROR: file ${file} is not readable!" >&2
     exit 3
elif [ ! \( -s "${file}" \) ]
then
     echo "%ERROR: file ${file} is empty!" >&2
     exit 4
fi

public static void main(String[] args) {
    List<String> list = Arrays.asList("one", "two", "three", "seven", "nine");
    AtomicBoolean yes = new AtomicBoolean(true);
    list.stream().takeWhile(value -> yes.get()).forEach(value -> {
        System.out.println("prior cond" + value);
        if (value.equals("two")) {
            System.out.println(value);
            yes.set(false);
        }

    });
    //System.out.println("Hello World");
}

For closing cmd window, especially after ending weblogic or JBOSS app servers console with Ctrl+C, I'm using 'call' command instead of 'start' in my batch files. My startWLS.cmd file then looks like:

call [BEA_HOME]\user_projects\domains\test_domain\startWebLogic.cmd

After Ctrl+C(and 'Y' answer) cmd window is automatically closed.

For the records, in OpenJPA before JPA2 it was @ElementDependant.

Instead of using regexp_replace multiple time use (\s) as given below;

SELECT regexp_replace('TEXT','(\s)','')
FROM dual;

The answers above all over complicate the story.

1. If you plan to have a mobile component, or need desktop users to work offline and then sync their work to a server you need CouchDB.
2. If your code will run only on the server then go with MongoDB

That's it. Unless you need CouchDB's (awesome) ability to replicate to mobile and desktop devices, MongoDB has the performance, community and tooling advantage at present.

Why not simply:

if (typeof myObject.myProperty == "undefined") alert("myProperty is not defined!");

Or if you expect a specific type:

if (typeof myObject.myProperty != "string") alert("myProperty has wrong type or does not exist!");

This fixes the box dead center on the screen:

        <td>

Use v.clear() to empty the vector.

If your vector contains pointers, clear calls the destructor for the object but does not delete the memory referenced by the pointer.

vector<SomeClass*> v(0);

v.push_back( new SomeClass("one") );

v.clear();  //Memory leak where "one" instance of SomeClass is lost

Why not just bypass the WebClient's file handling pieces altogether. Perhaps something similar to this:

    private void webBrowser1_Navigating(object sender, WebBrowserNavigatingEventArgs e)
    {
        e.Cancel = true;
        WebClient client = new WebClient();

        client.DownloadDataCompleted += new DownloadDataCompletedEventHandler(client_DownloadDataCompleted);

        client.DownloadDataAsync(e.Url);
    }

    void client_DownloadDataCompleted(object sender, DownloadDataCompletedEventArgs e)
    {
        string filepath = textBox1.Text;
        File.WriteAllBytes(filepath, e.Result);
        MessageBox.Show("File downloaded");
    }

$this->config->item() works fine.

For example, if the config file contains $config['foo'] = 'bar'; then $this->config->item('foo') == 'bar'

 var agencias = [];
 $('#Div input:checked').each(function(index, item){
 agencias.push(item.nextElementSibling.attributes.for.nodeValue);
 });

If you want to return some value then wrap your statement in function

function my_function(){ 

 return my_thing; 
}

Problem is with the statement on the 1st line if you are trying to use PHP

var ask = confirm ('".$message."'); 

IF you are trying to use PHP you should use

 var ask = confirm (<?php echo "'".$message."'" ?>); //now message with be the javascript string!!

A note to this old question:

My reset.css had set border-spacing: 0, causing the corners to get cut off. I had to set it to 3px for my radius to work properly (value will depend on the radius in question).

I think it is telling you exactly what is wrong. You cannot compare an integer with a varchar. PostgreSQL is strict and does not do any magic typecasting for you. I'm guessing SQLServer does typecasting automagically (which is a bad thing).

If you want to compare these two different beasts, you will have to cast one to the other using the casting syntax ::.

Something along these lines:

create view view1
as 
select table1.col1,table2.col1,table3.col3
from table1 
inner join
table2 
inner join 
table3
on 
table1.col4::varchar = table2.col5
/* Here col4 of table1 is of "integer" type and col5 of table2 is of type "varchar" */
/* ERROR: operator does not exist: integer = character varying */
....;

Notice the varchar typecasting on the table1.col4.

Also note that typecasting might possibly render your index on that column unusable and has a performance penalty, which is pretty bad. An even better solution would be to see if you can permanently change one of the two column types to match the other one. Literately change your database design.

Or you could create a index on the casted values by using a custom, immutable function which casts the values on the column. But this too may prove suboptimal (but better than live casting).

spin12.setLayoutParams(new LinearLayout.LayoutParams(200, 120));

spin12 is your spinner and 200,120 is width and height for your spinner.

David: Great direction, but you missed \r. this worked for me:

$array = preg_split("/(\r\n|\n|\r)/", $string);

What type of OS are you running on?

In order to assign more than 2GB of ram it needs to be at least a 64bit OS.

Then there is another problem. Even if your OS has Unlimited RAM, but that is fragmented in a way that not a single free block of 2GB is available, you'll get out of memory exceptions too. And keep in mind that the normal Heap memory is only part of the memory the VM process is using. So on a 32bit machine you will probably never be able to set Xmx to 2048MB.

I would also suggest to set min an max memory to the same value, because in this case as soon as the VM runs out of memory the frist time 1GB is allocated from the start, the VM then allocates a new block (assuming it increases with 500MB blocks) of 1,5GB after that is allocated, it would copy all the stuff from block one to the new one and free Memory after that. If it runs out of Memory again the 2GB are allocated and the 1,5 GB are then copied, temporarily allocating 3,5GB of memory.

Only using class names is not sufficient in your case.

• By.cssSelector(".ban") has 15 matching nodes
• By.cssSelector(".hot") has 11 matching nodes
• By.cssSelector(".ban.hot") has 5 matching nodes

Therefore you need more restrictions to narrow it down. Option 1 and 2 below are available for css selector, 1 might be the one that suits your needs best.

Option 1: Using list items' index (CssSelector or XPath)

Limitations

• Not stable enough if site's structure changes

Example:

driver.FindElement(By.CssSelector("#rightbar > .menu > li:nth-of-type(3) > h5"));
driver.FindElement(By.XPath("//*[@id='rightbar']/ul/li[3]/h5"));

Option 2: Using Selenium's FindElements, then index them. (CssSelector or XPath)

Limitations

• Not stable enough if site's structure changes
• Not the native selector's way

Example:

// note that By.CssSelector(".ban.hot") and //*[contains(@class, 'ban hot')] are different, but doesn't matter in your case
IList<IWebElement> hotBanners = driver.FindElements(By.CssSelector(".ban.hot"));
IWebElement banUsStates = hotBanners[3];

Option 3: Using text (XPath only)

Limitations

• Not for multilanguage sites
• Only for XPath, not for Selenium's CssSelector

Example:

driver.FindElement(By.XPath("//h5[contains(@class, 'ban hot') and text() = 'us states']"));

Option 4: Index the grouped selector (XPath only)

Limitations

• Not stable enough if site's structure changes
• Only for XPath, not CssSelector

Example:

driver.FindElement(By.XPath("(//h5[contains(@class, 'ban hot')])[3]"));

Option 5: Find the hidden list items link by href, then traverse back to h5 (XPath only)

Limitations

• Only for XPath, not CssSelector
• Low performance
• Tricky XPath

Example:

driver.FindElement(By.XPath(".//li[.//ul/li/a[contains(@href, 'geo.craigslist.org/iso/us/al')]]/h5"));

Commonly base64 it is used for images. if you like to decode an image (jpg in this example with org.apache.commons.codec.binary.Base64 package):

byte[] decoded = Base64.decodeBase64(imageJpgInBase64);
FileOutputStream fos = null;
fos = new FileOutputStream("C:\\output\\image.jpg");
fos.write(decoded);
fos.close();

Maxdepth

I found it works nicely with Jim Lewis's answer just add a bit like this:

$ export DIR=/path/dir && cd $DIR && chmod -R +x *
$ find . -maxdepth 1 -type f -name '*.sh' -exec {} \; > results.out

Sort Order

If you want to execute in sort order, modify it like this:

$ export DIR=/path/dir && cd $DIR && chmod -R +x *
find . -maxdepth 2 -type f -name '*.sh' | sort | bash > results.out

Just for an example, this will execute with following order:

bash: 1: ./assets/main.sh
bash: 2: ./builder/clean.sh
bash: 3: ./builder/concept/compose.sh
bash: 4: ./builder/concept/market.sh
bash: 5: ./builder/concept/services.sh
bash: 6: ./builder/curl.sh
bash: 7: ./builder/identity.sh
bash: 8: ./concept/compose.sh
bash: 9: ./concept/market.sh
bash: 10: ./concept/services.sh
bash: 11: ./product/compose.sh
bash: 12: ./product/market.sh
bash: 13: ./product/services.sh
bash: 14: ./xferlog.sh

Unlimited Depth

If you want to execute in unlimited depth by certain condition, you can use this:

export DIR=/path/dir && cd $DIR && chmod -R +x *
find . -type f -name '*.sh' | sort | bash > results.out

then put on top of each files in the child directories like this:

#!/bin/bash
[[ "$(dirname `pwd`)" == $DIR ]] && echo "Executing `realpath $0`.." || return

and somewhere in the body of parent file:

if <a condition is matched>
then
    #execute child files
    export DIR=`pwd`
fi

If you have Pillow installed with scipy and it is still giving you error then check your scipy version because it has been removed from scipy since 1.3.0rc1.

rather install scipy 1.1.0 by :

pip install scipy==1.1.0

check https://github.com/scipy/scipy/issues/6212

The method imread in scipy.misc requires the forked package of PIL named Pillow. If you are having problem installing the right version of PIL try using imread in other packages:

from matplotlib.pyplot import imread
im = imread(image.png)

To read jpg images without PIL use:

import cv2 as cv
im = cv.imread(image.jpg)

You can try from scipy.misc.pilutil import imread instead of from scipy.misc import imread

Please check the GitHub page : https://github.com/amueller/mglearn/issues/2 for more details.

An alternative approach, which I've recently implemented, is to use the div-table plugin with panflute.

This creates a table from a set of fenced divs (standard in the pandoc implementation of markdown), in a similar layout to html:

---
panflute-filters: [div-table]
panflute-path: 'panflute/docs/source'
---

::::: {.divtable}
:::: {.tcaption}
a caption here (optional), only the first paragraph is used.
::::
:::: {.thead}
[Header 1]{width=0.4 align=center}
[Header 2]{width=0.6 align=default}
::::
:::: {.trow}
::: {.tcell}

1. any
2. normal markdown
3. can go in a cell

:::
::: {.tcell}

some text

Then each paragraph will be treated as a separate column

Looks like:

Assuming you're getting norm from scipy.stats, you probably just need to sort your list:

import numpy as np
import scipy.stats as stats
import matplotlib.pyplot as plt

h = [186, 176, 158, 180, 186, 168, 168, 164, 178, 170, 189, 195, 172,
     187, 180, 186, 185, 168, 179, 178, 183, 179, 170, 175, 186, 159,
     161, 178, 175, 185, 175, 162, 173, 172, 177, 175, 172, 177, 180]
h.sort()
hmean = np.mean(h)
hstd = np.std(h)
pdf = stats.norm.pdf(h, hmean, hstd)
plt.plot(h, pdf) # including h here is crucial

And so I get:

Remove Padding: 10%; or use px instead of percent for .wrap

see the example : http://jsfiddle.net/C93mk/493/

HTML :

<div id="wrapper">
    <div id="wrap">
    Some relative item placed item
    <div id="fixed"></div>
    </div>
</div>

CSS:

body{ height:20000px }
#wrapper {padding:10%;}
#wrap{ 
    float: left;
    position: relative;
    width: 200px; 
    background:#ccc; 
}
#fixed{ 
    position:fixed;
    width:inherit;
    padding:0px;
    height:10px;
    background-color:#333;

}

Here's how I do it.

function validate(phone) {_x000D_
  const regex = /^\(?([0-9]{3})\)?[-. ]?([0-9]{3})[-. ]?([0-9]{4})$/;_x000D_
  console.log(regex.test(phone))_x000D_
}_x000D_
_x000D_
validate('1234567890')     // true_x000D_
validate(1234567890)       // true_x000D_
validate('(078)789-8908')  // true_x000D_
validate('123-345-3456')   // true

it work in my case, oldSensor and newSnsor - oldView and newView:

private void replaceSensors(View oldSensor, View newSensor) {
            ViewGroup parent = (ViewGroup) oldSensor.getParent();

            if (parent == null) {
                return;
            }

            int indexOldSensor = parent.indexOfChild(oldSensor);
            int indexNewSensor = parent.indexOfChild(newSensor);
            parent.removeView(oldSensor);
            parent.addView(oldSensor, indexNewSensor);
            parent.removeView(newSensor);
            parent.addView(newSensor, indexOldSensor);
        }

method1 = '[x[1] for x in elements]'
method2 = 'map(itemgetter(1), elements)'
method3 = 'dict(elements).values()'
method4 = 'zip(*elements)[1]'

import timeit
t = timeit.Timer(method1, setup)
print('Method 1: ' + str(t.timeit(100)))
t = timeit.Timer(method2, setup)
print('Method 2: ' + str(t.timeit(100)))
t = timeit.Timer(method3, setup)
print('Method 3: ' + str(t.timeit(100)))
t = timeit.Timer(method4, setup)
print('Method 4: ' + str(t.timeit(100)))

Method 1: 0.618785858154
Method 2: 0.711684942245
Method 3: 0.298138141632
Method 4: 1.32586884499

So over twice as fast if you have a 2 tuple pair to just convert to a dict and take the values.

You can try something like:

var str = "a,d,k";
str.replace(/,/g, "");

You can create lib folder inside app you press right click and select directory you named as libs its will be worked

If you like long cuts, here is another way tuple(tuple(a_m.tolist()) for a_m in a )

from numpy import array
a = array([[1, 2],
           [3, 4]])
tuple(tuple(a_m.tolist()) for a_m in a )

The output is ((1, 2), (3, 4))

Note just (tuple(a_m.tolist()) for a_m in a ) will give a generator expresssion. Sort of inspired by @norok2's comment to Greg von Winckel's answer

function final_submit1() {
    var city = $("#city").val();
    var airport = $("#airport").val();

    var vehicle = $("#vehicle").val();

    if(city && airport){
    $.ajax({
        type:"POST",
        cache:false,
        data:{"city": city,"airport": airport},
        url:'http://airportLimo/ajax-car-list', 
        success: function (html) {
             console.log(html);
          //$('#add').val('data sent');
          //$('#msg').html(html);
           $('#pprice').html("Price: $"+html);
        }
      });

    }  
}

You can't redirect to a function. What you can do is pass some flag on the URL when redirecting, then check that flag in the server side code and if raised, execute the function.

For example:

document.location = "MyPage.php?action=DoThis";

Then in your PHP code check for "action" in the query string and if equal to "DoThis" execute whatever function you need.

My 2cents, in a single system user you can set the port also on /etc/ssh/ssh_config then rsync will use the port set here

<h4>Order List</h4>
<ul>
    <li ng-repeat="val in filter_option.order">
        <span>
            <input title="{{filter_option.order_name[$index]}}" type="radio" ng-model="filter_param.order_option" ng-value="'{{val}}'" />
            &nbsp;{{filter_option.order_name[$index]}}
        </span>
        <select title="" ng-model="filter_param[val]">
            <option value="asc">Asc</option>
            <option value="desc">Desc</option>
        </select>
    </li>
</ul>

What does the UDF EntityHasProfile() do?

Typically you could do something like this with a LEFT JOIN:

SELECT EntityId, EntityName, CASE WHEN EntityProfileIs IS NULL THEN 0 ELSE 1 END AS Has Profile
FROM Entities
LEFT JOIN EntityProfiles
    ON EntityProfiles.EntityId = Entities.EntityId

This should eliminate a need for a costly scalar UDF call - in my experience, scalar UDFs should be a last resort for most database design problems in SQL Server - they are simply not good performers.

I've adapter the answer of ltiong_sh to work for me:

function nextField(current){
    var elements = document.getElementById("my-form").elements;
    var exit = false;
    for(i = 0; i < elements.length; i++){   
        if (exit) {
            elements[i].focus();
            if (elements[i].type == 'text'){
                elements[i].select();
            }   
            break;
        }
        if (elements[i].isEqualNode(current)) { 
            exit = true;
        }       
    }
}

Use:

from datetime import datetime

current_month = datetime.now().strftime('%m') // 02 //This is 0 padded
current_month_text = datetime.now().strftime('%h') // Feb
current_month_text = datetime.now().strftime('%B') // February

current_day = datetime.now().strftime('%d')   // 23 //This is also padded
current_day_text = datetime.now().strftime('%a')  // Fri
current_day_full_text = datetime.now().strftime('%A')  // Friday

current_weekday_day_of_today = datetime.now().strftime('%w') //5  Where 0 is Sunday and 6 is Saturday.

current_year_full = datetime.now().strftime('%Y')  // 2018
current_year_short = datetime.now().strftime('%y')  // 18 without century

current_second= datetime.now().strftime('%S') //53
current_minute = datetime.now().strftime('%M') //38
current_hour = datetime.now().strftime('%H') //16 like 4pm
current_hour = datetime.now().strftime('%I') // 04 pm

current_hour_am_pm = datetime.now().strftime('%p') // 4 pm

current_microseconds = datetime.now().strftime('%f') // 623596 Rarely we need.

current_timzone = datetime.now().strftime('%Z') // UTC, EST, CST etc. (empty string if the object is naive).

Reference: strftime() and strptime() Behavior

The above things are useful for any date parsing, not only now or today. It can be useful for any date parsing.

e.g.
my_date = "23-02-2018 00:00:00"

datetime.strptime(str(my_date),'%d-%m-%Y %H:%M:%S').strftime('%Y-%m-%d %H:%M:%S+00:00')

datetime.strptime(str(my_date),'%d-%m-%Y %H:%M:%S').strftime('%m')

And so on...

Here is how I did this:

first make interface

interface NavigationInterface {
    fun closeActivity()
}

next make sure activity implements interface and overrides interface method(s)

class NotesActivity : AppCompatActivity(), NavigationInterface {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_notes)
        setSupportActionBar(findViewById(R.id.toolbar))
    }

    override fun closeActivity() {
        this.finish()
    }
}

then make sure to create interface listener in fragment

private lateinit var navigationInterface: NavigationInterface

override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
): View? {
    //establish interface communication
    activity?.let {
        instantiateNavigationInterface(it)
    }
    // Inflate the layout for this fragment
    return inflater.inflate(R.layout.fragment_notes_info, container, false)
}

private fun instantiateNavigationInterface(context: FragmentActivity) {
    navigationInterface = context as NavigationInterface
}

then you can make calls like such:

view.findViewById<Button>(R.id.button_second).setOnClickListener {
    navigationInterface.closeActivity()
}

1. Create a file in drawable play_pause.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_selected="true"
          android:drawable="@drawable/pause" />

    <item android:state_selected="false"
          android:drawable="@drawable/play" />
    <!-- default -->
</selector>

2. In xml file add this below code

 <ImageView
                android:id="@+id/iv_play"
                android:layout_width="@dimen/_50sdp"
                android:layout_height="@dimen/_50sdp"
                android:layout_centerInParent="true"
                android:layout_centerHorizontal="true"
                android:background="@drawable/pause_button"
                android:gravity="center"
                android:scaleType="fitXY" />

3. In java file add this below code

iv_play = (ImageView) findViewById(R.id.iv_play);
iv_play.setSelected(false);

and also add this

iv_play.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                iv_play.setSelected(!iv_play.isSelected());
                if (iv_play.isSelected()) {
                    ((GifDrawable) gif_1.getDrawable()).start();
                    ((GifDrawable) gif_2.getDrawable()).start();
                } else {
                    iv_play.setSelected(false);
                    ((GifDrawable) gif_1.getDrawable()).stop();
                    ((GifDrawable) gif_2.getDrawable()).stop();
                }
            }
        });

You could try this:

        <script type="text/javascript">
         function newWindow(url){
                window.open(url);
            }
        </script>

And call the function

Given -

<input name="foo" type="text" value="foo" readonly />

this works - (jquery 1.7.1)

$('input[name="foo"]').prop('readonly', true);

tested with readonly and readOnly - both worked.

Just to elaborate on the excellent answer from K3---rnc, here is a more generic version:

def onehottify(x, n=None, dtype=float):
    """1-hot encode x with the max value n (computed from data if n is None)."""
    x = np.asarray(x)
    n = np.max(x) + 1 if n is None else n
    return np.eye(n, dtype=dtype)[x]

Also, here is a quick-and-dirty benchmark of this method and a method from the currently accepted answer by YXD (slightly changed, so that they offer the same API except that the latter works only with 1D ndarrays):

def onehottify_only_1d(x, n=None, dtype=float):
    x = np.asarray(x)
    n = np.max(x) + 1 if n is None else n
    b = np.zeros((len(x), n), dtype=dtype)
    b[np.arange(len(x)), x] = 1
    return b

The latter method is ~35% faster (MacBook Pro 13 2015), but the former is more general:

>>> import numpy as np
>>> np.random.seed(42)
>>> a = np.random.randint(0, 9, size=(10_000,))
>>> a
array([6, 3, 7, ..., 5, 8, 6])
>>> %timeit onehottify(a, 10)
188 µs ± 5.03 µs per loop (mean ± std. dev. of 7 runs, 10000 loops each)
>>> %timeit onehottify_only_1d(a, 10)
139 µs ± 2.78 µs per loop (mean ± std. dev. of 7 runs, 10000 loops each)

On Ubuntu you can enable a cron.log file to contain just the CRON entries.

Uncomment the line that mentions cron in /etc/rsyslog.d/50-default.conf file:

#  Default rules for rsyslog.
#

#                       For more information see rsyslog.conf(5) and /etc/rsyslog.conf

#
# First some standard log files.  Log by facility.
#
auth,authpriv.*                 /var/log/auth.log
*.*;auth,authpriv.none          -/var/log/syslog
#cron.*                          /var/log/cron.log

Save and close the file and then restart the rsyslog service:

sudo systemctl restart rsyslog

You can now see cron log entries in its own file:

sudo tail -f /var/log/cron.log

Sample outputs:

Jul 18 07:05:01 machine-host-name CRON[13638]: (root) CMD (command -v debian-sa1 > /dev/null && debian-sa1 1 1)

However, you will not see more information about what scripts were actually run inside /etc/cron.daily or /etc/cron.hourly, unless those scripts direct output to the cron.log (or perhaps to some other log file).

If you want to verify if a crontab is running and not have to search for it in cron.log or syslog, create a crontab that redirects output to a log file of your choice - something like:

# For more information see the manual pages of crontab(5) and cron(8)
#
# m h  dom mon dow   command
30 2 * * 1 /usr/local/sbin/certbot-auto renew >> /var/log/le-renew.log 2>&1

Steps taken from: https://www.cyberciti.biz/faq/howto-create-cron-log-file-to-log-crontab-logs-in-ubuntu-linux/

Following is worked for me

git reset HEAD

I was getting following error

git stash
src/config.php: needs merge
src/config.php: needs merge
src/config.php: unmerge(230a02b5bf1c6eab8adce2cec8d573822d21241d)
src/config.php: unmerged (f5cc88c0fda69bf72107bcc5c2860c3e5eb978fa)

Then i ran

git reset HEAD

it worked

From the error it seems that you are trying to import something which is not a class.

If your MyFunctions is a class, you should import it like this:

<%@page import="com.TransportPortal.MyFunctions"%>

If it is a package and you want to import everything in the package you should do like this:

<%@page import="com.TransportPortal.MyFunctions.* "%>

Edit:

There are two cases which will give you this error, edited to cover both.

As of BeautifulSoup 4+ ,

If you have a single class name , you can just pass the class name as parameter like :

mydivs = soup.find_all('div', 'class_name')

Or if you have more than one class names , just pass the list of class names as parameter like :

mydivs = soup.find_all('div', ['class1', 'class2'])

Swift version

This is the Swift version of David's Objective-C answer. You use the global queue to run things in the background and the main queue to update the UI.

DispatchQueue.global(qos: .background).async {
    
    // Background Thread
    
    DispatchQueue.main.async {
        // Run UI Updates
    }
}

You can install SideBarEnhancements plugin, which among other things will give you ability to open file in browser just by clicking F12.

To open exactly in Chrome, you will need to fix up “Side Bar.sublime-settings” file and set "default_browser" to be "chrome".

I also recommend to learn this video tutorial on Sublime Text 2.

Just another suggestion, removing any trailing white-space

limitStrLength = (text, max_length) => {
    if(text.length > max_length - 3){
        return text.substring(0, max_length).trimEnd() + "..."
    }
    else{
        return text
    }

here's a generic approach which makes it easy for me because I keep connecting to several servers (SQL, Teradata, Hive etc.) from python. Hence, I use the pyodbc connector. Here's some basic steps to get going with pyodbc (in case you have never used it):

• Pre-requisite: You should have the relevant ODBC connection in your windows setup before you follow the below steps. In case you don't have it, find the same here

Once complete: STEP 1. pip install: pip install pyodbc (here's the link to download the relevant driver from Microsoft's website)

STEP 2. now, import the same in your python script:

import pyodbc

STEP 3. Finally, go ahead and give the connection details as follows:

conn_hive = pyodbc.connect('DSN = YOUR_DSN_NAME , SERVER = YOUR_SERVER_NAME, UID = USER_ID, PWD = PSWD' )

The best part of using pyodbc is that I have to import just one package to connect to almost any data source.

in your servlet

 request.setAttribute("submitDone","done");
 return mapping.findForward("success");

In your jsp

<c:if test="${not empty submitDone}">
  <script>alert("Form submitted");
</script></c:if>

First, you should disable selinux, edit file /etc/sysconfig/selinux so it looks like this:

SELINUX=disabled
SELINUXTYPE=targeted

Save file and restart system.

Then you can add the new rule to iptables:

iptables -A INPUT -m state --state NEW -p tcp --dport 8080 -j ACCEPT

and restart iptables with /etc/init.d/iptables restart

If it doesn't work you should check other network settings.

Whenever I set debug="off" in my web.config and run my mvc4 application i would end up with ...

<script src="/bundles/jquery?v=<some long string>"></script>

in my html code and a JavaScript error

Expected ';'

There were 2 ways to get rid of the javascript error

1. set BundleTable.EnableOptimizations = false in BundleConfig.cs

OR

2. I ended up using NuGet Package Manager to update WebGrease.dll. It works fine irrespective if debug= "true" or debug = "false".

You will also get this if you try to connect to the wrong URL ;)

I have two endpoints and services defined in my system, with similar names.

Got this exact error when the URLs got swapped on my client at some point. Really scratched the head until finally figuring out this dumb mistake.

[A1].End(xlUp)
[A1].End(xlDown)
[A1].End(xlToLeft)
[A1].End(xlToRight)

is the VBA equivalent of being in Cell A1 and pressing Ctrl + Any arrow key. It will continue to travel in that direction until it hits the last cell of data, or if you use this command to move from a cell that is the last cell of data it will travel until it hits the next cell containing data.

If you wanted to find that last "used" cell in Column A, you could go to A65536 (for example, in an XL93-97 workbook) and press Ctrl + Up to "snap" to the last used cell. Or in VBA you would write:

Range("A65536").End(xlUp) which again can be re-written as Range("A" & Rows.Count).End(xlUp) for compatibility reasons across workbooks with different numbers of rows.

You may try like this:

import java.applet.Applet;
import java.awt.*;

public class Rect1 extends Applet {

  public void paint (Graphics g) {
    g.drawRect (x, y, width, height);    //can use either of the two//
    g.fillRect (x, y, width, height);
    g.setColor(color);
  }

}

where x is x co-ordinate y is y cordinate color=the color you want to use eg Color.blue

if you want to use rectangle object you could do it like this:

import java.applet.Applet;
import java.awt.*;

public class Rect1 extends Applet {

  public void paint (Graphics g) {    
    Rectangle r = new Rectangle(arg,arg1,arg2,arg3);
    g.fillRect(r.getX(), r.getY(), r.getWidth(), r.getHeight());
    g.setColor(color);
  }
}       

Update 2020: C# 8.0 finally makes this easy:

> "C# 8.0 finally makes this easy"[^4..]
"easy"

You can also slice arrays in the same way, see Indices and ranges.

You can also try using strpbrk() for the negation (none of the letters have been found):

$find_letters = array('a', 'c', 'd');
$string = 'abcdefg';

if(strpbrk($string, implode($find_letters)) === false)
{
    echo 'None of these letters are found in the string!';
}

@lru_cache is not perfect with default function values

my mem decorator:

import inspect


def get_default_args(f):
    signature = inspect.signature(f)
    return {
        k: v.default
        for k, v in signature.parameters.items()
        if v.default is not inspect.Parameter.empty
    }


def full_kwargs(f, kwargs):
    res = dict(get_default_args(f))
    res.update(kwargs)
    return res


def mem(func):
    cache = dict()

    def wrapper(*args, **kwargs):
        kwargs = full_kwargs(func, kwargs)
        key = list(args)
        key.extend(kwargs.values())
        key = hash(tuple(key))
        if key in cache:
            return cache[key]
        else:
            res = func(*args, **kwargs)
            cache[key] = res
            return res
    return wrapper

and code for testing:

from time import sleep


@mem
def count(a, *x, z=10):
    sleep(2)
    x = list(x)
    x.append(z)
    x.append(a)
    return sum(x)


def main():
    print(count(1,2,3,4,5))
    print(count(1,2,3,4,5))
    print(count(1,2,3,4,5, z=6))
    print(count(1,2,3,4,5, z=6))
    print(count(1))
    print(count(1, z=10))


if __name__ == '__main__':
    main()

result - only 3 times with sleep

but with @lru_cache it will be 4 times, because this:

print(count(1))
print(count(1, z=10))

will be calculated twice (bad working with defaults)

use this function it works for me

public byte[] toByteArray(int value) {
    return new byte[] {
            (byte)(value >> 24),
            (byte)(value >> 16),
            (byte)(value >> 8),
            (byte)value};
}

it translates the int into a byte value

There are probably ways of doing that with builtin functions in all shells but it would be less portable. I've not checked the POSIX sh specs to see whether it has such capabilities.

Here's how you would do this in JavaScript, this is a really efficient way to do it!

let data = "{ "name": "mark"}"
let object = JSON.parse(data);
console.log(object.name);

this would print mark

Very basic but

• $.load(): Load a piece of html into a container DOM.
• $.get(): Use this if you want to make a GET call and play extensively with the response.
• $.post(): Use this if you want to make a POST call and don’t want to load the response to some container DOM.
• $.ajax(): Use this if you need to do something when XHR fails, or you need to specify ajax options (e.g. cache: true) on the fly.

There is no explicit Clone button. Basically what you do is create an image, or snapshot of an existing EC2 instance, and then spin up a new instance using that snapshot.

First create an image from an existing EC2 instance.

Check your snapshots list to see if the process is completed. This usually takes around 20 minutes depending on how large your instance drive is.

Then, you need to create a new instance and use that image as the AMI.

Credit to EM0 for https://stackoverflow.com/a/17600012/4151626

The other solutions (including EM0's) still deadlocked for my application, due to internal timeouts and the use of both StandardOutput and StandardError by the spawned application. Here is what worked for me:

Process p = new Process()
{
  StartInfo = new ProcessStartInfo()
  {
    FileName = exe,
    Arguments = args,
    UseShellExecute = false,
    RedirectStandardOutput = true,
    RedirectStandardError = true
  }
};
p.Start();

string cv_error = null;
Thread et = new Thread(() => { cv_error = p.StandardError.ReadToEnd(); });
et.Start();

string cv_out = null;
Thread ot = new Thread(() => { cv_out = p.StandardOutput.ReadToEnd(); });
ot.Start();

p.WaitForExit();
ot.Join();
et.Join();

Edit: added initialization of StartInfo to code sample

The double arrow operator, =>, is used as an access mechanism for arrays. This means that what is on the left side of it will have a corresponding value of what is on the right side of it in array context. This can be used to set values of any acceptable type into a corresponding index of an array. The index can be associative (string based) or numeric.

$myArray = array(
    0 => 'Big',
    1 => 'Small',
    2 => 'Up',
    3 => 'Down'
);

The object operator, ->, is used in object scope to access methods and properties of an object. It’s meaning is to say that what is on the right of the operator is a member of the object instantiated into the variable on the left side of the operator. Instantiated is the key term here.

// Create a new instance of MyObject into $obj
$obj = new MyObject();
// Set a property in the $obj object called thisProperty
$obj->thisProperty = 'Fred';
// Call a method of the $obj object named getProperty
$obj->getProperty();

The problem is that when you are doing additions and multiplications of numbers all with two decimal places, you expect there will be no rounding errors, but remember the internal representation of double is in base 2, not in base 10 ! So a number like 0.1 in base 10 may be in base 2 : 0.101010101010110011... with an infinite number of decimals (the value stored in the double will be a number N with :

 0.1-Math.Pow(2,-64) < N < 0.1+Math.Pow(2,-64) 

As a consequence an operation like 12.3 + 0.1 may be not the same exact 64 bits double value as 12.4 (or 12.456 * 10 may be not the same as 124.56) because of rounding errors. For example if you store in a Database the result of 12.3 +0.1 into a table/column field of type double precision number and then SELECT WHERE xx=12.4 you may realize that you stored a number that is not exactly 12.4 and the Sql select will not return the record; So if you cannot use the decimal datatype (which has internal representation in base 10) and must use the 'double' datatype, you have to do some normalization after each addition or multiplication :

double freqMHz= freqkHz.MulRound(0.001); // freqkHz*0.001
double amountEuro= amountEuro.AddRound(delta); // amountEuro+delta


    public static double AddRound(this double d,double val)
    {
        return double.Parse(string.Format("{0:g14}", d+val));
    }
    public static double MulRound(this double d,double val)
    {
        return double.Parse(string.Format("{0:g14}", d*val));
    }

Here is a very good way to handle this (found on ozgrid):

Let's say your list is on Sheet2 and you wish to use the Validation List with AutoComplete on Sheet1.

On Sheet1 A1 Enter =Sheet2!A1 and copy down including as many spare rows as needed (say 300 rows total). Hide these rows and use this formula in the Refers to: for a dynamic named range called MyList:

=OFFSET(Sheet1!$A$1,0,0,MATCH("*",Sheet1!$A$1:$A$300,-1),1)

Now in the cell immediately below the last hidden row use Data Validation and for the List Source use =MyList

[EDIT] Adapted version for Excel 2007+ (couldn't test on 2010 though but AFAIK, there is nothing really specific to a version).
Let's say your data source is on Sheet2!A1:A300 and let's assume your validation list (aka autocomplete) is on cell Sheet1!A1.

1. Create a dynamic named range MyList that will depend on the value of the cell where you put the validation

   =OFFSET(Sheet2!$A$1,MATCH(Sheet1!$A$1&"*",Sheet2!$A$1:$A$300,0)-1,0,COUNTA(Sheet2!$A:$A))

2. Add the validation list on cell Sheet1!A1 that will refert to the list =MyList

Caveats

1. This is not a real autocomplete as you have to type first and then click on the validation arrow : the list will then begin at the first matching element of your list

2. The list will go till the end of your data. If you want to be more precise (keep in the list only the matching elements), you can change the COUNTA with a SUMLPRODUCT that will calculate the number of matching elements

3. Your source list must be sorted

<?php
$myfile = fopen("webdictionary.txt", "r") or die("Unable to open file!");
echo fread($myfile,filesize("webdictionary.txt"));
fclose($myfile);
?>

Try this to open a file in php

If by "given enough time" you mean 100 years and you're creating them at a rate of a billion a second, then yes, you have a 50% chance of having a collision after 100 years.

To get a char from a Scanner, you can use the findInLine method.

    Scanner sc = new Scanner("abc");
    char ch = sc.findInLine(".").charAt(0);
    System.out.println(ch); // prints "a"
    System.out.println(sc.next()); // prints "bc"

If you need a bunch of char from a Scanner, then it may be more convenient to (perhaps temporarily) change the delimiter to the empty string. This will make next() returns a length-1 string every time.

    Scanner sc = new Scanner("abc");
    sc.useDelimiter("");
    while (sc.hasNext()) {
        System.out.println(sc.next());
    } // prints "a", "b", "c"

 Constant   Value               Description
 ----------------------------------------------------------------
 vbCr       Chr(13)             Carriage return
 vbCrLf     Chr(13) & Chr(10)   Carriage return–linefeed combination
 vbLf       Chr(10)             Line feed

• vbCr : - return to line beginning
  Represents a carriage-return character for print and display functions.

• vbCrLf : - similar to pressing Enter
  Represents a carriage-return character combined with a linefeed character for print and display functions.

• vbLf : - go to next line
  Represents a linefeed character for print and display functions.

What language?? There are different tools for almost every imaginable programming language, since they all have different syntactic rules and conventions.

Good ol' indent is a nice, customizable, command-line utility to format C and C++ programs.

The web site likely uses cookies to store your session information. When you run

curl --user user:pass https://xyz.com/a  #works ok
curl https://xyz.com/b #doesn't work

curl is run twice, in two separate sessions. Thus when the second command runs, the cookies set by the 1st command are not available; it's just as if you logged in to page a in one browser session, and tried to access page b in a different one.

What you need to do is save the cookies created by the first command:

curl --user user:pass --cookie-jar ./somefile https://xyz.com/a

and then read them back in when running the second:

curl --cookie ./somefile https://xyz.com/b

Alternatively you can try downloading both files in the same command, which I think will use the same cookies.

You have to aggregate by anything NOT IN the group by clause.

So,there are two options...Add Credit_Initial and Disponible_v to the group by

OR

Change them to MAX( Credit_Initial ) as Credit_Initial, MAX( Disponible_v ) as Disponible_v if you know the values are constant anyhow and have no other impact.

According to Apple documentation of NSDate compare:

Returns an NSComparisonResult value that indicates the temporal ordering of the receiver and another given date.

- (NSComparisonResult)compare:(NSDate *)anotherDate

Parameters anotherDate

The date with which to compare the receiver. This value must not be nil. If the value is nil, the behavior is undefined and may change in future versions of Mac OS X.

Return Value

If:

The receiver and anotherDate are exactly equal to each other, NSOrderedSame

The receiver is later in time than anotherDate, NSOrderedDescending

The receiver is earlier in time than anotherDate, NSOrderedAscending

In other words:

if ([date1 compare:date2] == NSOrderedSame) ...

Note that it might be easier in your particular case to read and write this :

if ([date2 isEqualToDate:date2]) ...

See Apple Documentation about this one.

I usually just run ez_setup.py. IIRC, that works fine, at least with UAC off.

It also creates an easy_install executable in your Python\scripts subdirectory, which should be in your PATH.

UPDATE: I highly recommend not to bother with easy_install anymore! Jump right to pip, it's better in every regard!
Installation is just as simple: from the installation instructions page, you can download get-pip.py and run it. Works just like the ez_setup.py mentioned above.

You may have to use =IF(ISNUMBER(A1),A1,1) in some situations where you are looking for number values in cell.

You don't need the directory on your path. You could put it on your path, but you don't NEED to do that.
If you are calling regasm rarely, or calling it from a batch file, you may find it is simpler to just invoke regasm via the fully-qualified pathname on the exe, eg:

Changing the repo url from ssh to https is not very meaningful to me. As I prefer ssh over https because of some sort of extra benefits which I don't want to discard. Above answers are pretty good and accurate. If you face this problem in GitLab, please go to their official documentation page and change your config file like that.

Host gitlab.com
  Hostname altssh.gitlab.com

Laravel 5

The other answers are great for Laravel 4 but Laravel 5 is here! We now have the ability to generate all kinds of stuff by default. Run php artisan help to view all artisan commands. Here are all of the make commands:

make
  make:command         Create a new command class
  make:console         Create a new Artisan command
  make:controller      Create a new resource controller class
  make:event           Create a new event class
  make:middleware      Create a new middleware class
  make:migration       Create a new migration file
  make:model           Create a new Eloquent model class
  make:provider        Create a new service provider class
  make:request         Create a new form request class

Note: we no longer use item:make. Instead we now have make:item.

Run php artisan help make:item to see what you can pass it. For instance php artisan help make:migration shows that we need to pass it the migration name but we can also pass it --create="" or --table="" to specify the table name to create or modify respectively. Run php artisan make:migration create_articles_table --create="articles" to generate the articles table. Moreover, generating models takes care of generating the migration for that model. Follow the naming conventions and it will be pluralized it for the migration.

You're trying to do &(2), &(4) which won't work

#romtest {

}

A major difference is that DateTimeOffset can be used in conjunction with TimeZoneInfo to convert to local times in timezones other than the current one.

This is useful on a server application (e.g. ASP.NET) that is accessed by users in different timezones.

I searched for some good themes across internet and found nothing. So I ported selected controls of GTK Hybrid theme. It's MIT licensed and you can find it here:

It's not enterprise grade style and probably has some flaws, but I use it in my personal projects.

If you need to open the DevTools press ctrl-shift-i.

If the DevTools window is already opened you can use the ctrl-shift-d shortcut; it switches the window into a detached mode.

For example in my case the electron application window (Chrome) is really small.

It's not possible to use any other suggestions except the ctrl-shift-d shortcut

By the way, it's worth noting that some mobile devices, particularly Apple products like iPhone/iPad completely ignore headers like no-cache, no-store, Expires: 0, or whatever else you may try to force them to not re-use expired form pages.

This has caused us no end of headaches as we try to get the issue of a user's iPad say, being left asleep on a page they have reached through a form process, say step 2 of 3, and then the device totally ignores the store/cache directives, and as far as I can tell, simply takes what is a virtual snapshot of the page from its last state, that is, ignoring what it was told explicitly, and, not only that, taking a page that should not be stored, and storing it without actually checking it again, which leads to all kinds of strange Session issues, among other things.

I'm just adding this in case someone comes along and can't figure out why they are getting session errors with particularly iphones and ipads, which seem by far to be the worst offenders in this area.

I've done fairly extensive debugger testing with this issue, and this is my conclusion, the devices ignore these directives completely.

Even in regular use, I've found that some mobiles also totally fail to check for new versions via say, Expires: 0 then checking last modified dates to determine if it should get a new one.

It simply doesn't happen, so what I was forced to do was add query strings to the css/js files I needed to force updates on, which tricks the stupid mobile devices into thinking it's a file it does not have, like: my.css?v=1, then v=2 for a css/js update. This largely works.

User browsers also, by the way, if left to their defaults, as of 2016, as I continuously discover (we do a LOT of changes and updates to our site) also fail to check for last modified dates on such files, but the query string method fixes that issue. This is something I've noticed with clients and office people who tend to use basic normal user defaults on their browsers, and have no awareness of caching issues with css/js etc, almost invariably fail to get the new css/js on change, which means the defaults for their browsers, mostly MSIE / Firefox, are not doing what they are told to do, they ignore changes and ignore last modified dates and do not validate, even with Expires: 0 set explicitly.

This was a good thread with a lot of good technical information, but it's also important to note how bad the support for this stuff is in particularly mobile devices. Every few months I have to add more layers of protection against their failure to follow the header commands they receive, or to properly interpet those commands.

Facebook publishes the SDK on maven central :

Just add :

repositories {
    jcenter()       // IntelliJ main repo.
}

dependencies {
    compile 'com.facebook.android:facebook-android-sdk:+'
}

The accepted answer did not work for me in all browsers, but following css did work for me:

tr    
{ 
  display: table-row-group;
  page-break-inside:avoid; 
  page-break-after:auto;
}

The html structure was:

<table>
  <thead>
    <tr></tr>
  </thead>
  <tbody>
    <tr></tr>
    <tr></tr>
    ...
  </tbody>
</table>

In my case, there were some additional issues with the thead tr, but this resolved the original issue of keeping the table rows from breaking.

Because of the header issues, I ultimately ended up with:

#theTable td *
{
  page-break-inside:avoid;
}

This didn't prevent rows from breaking; just each cell's content.

In order to hide the exception:

For Hibernate 5.2 (and Spring Boot 2.0), you can either use the use_jdbc_metadata_defaults property that the others pointed out:

# Meant to hide HHH000424: Disabling contextual LOB creation as createClob() method threw error 
spring.jpa.properties.hibernate.temp.use_jdbc_metadata_defaults: false

Or, if you want to not have any side effects from the above setting (there's a comment warning us about some Oracle side effects, I don't know if it's valid or not), you can just disable the logging of the exception like this:

logging:
   level: 
      # Hides HHH000424: Disabling contextual LOB creation as createClob() method threw error 
      org.hibernate.engine.jdbc.env.internal.LobCreatorBuilderImpl: WARN

It is also important to encode the rest of the text in order to protect from possible script injection attacks

function insertTextWithLineBreaks(text, targetElement) {
    var textWithNormalizedLineBreaks = text.replace('\r\n', '\n');
    var textParts = textWithNormalizedLineBreaks.split('\n');

    for (var i = 0; i < textParts.length; i++) {
        targetElement.appendChild(document.createTextNode(textParts[i]));
        if (i < textParts.length - 1) {
            targetElement.appendChild(document.createElement('br'));
        }
    }
}

EditText state = (EditText) findViewById(R.id.txtState);


                Pattern ps = Pattern.compile("^[a-zA-Z ]+$");
                Matcher ms = ps.matcher(state.getText().toString());
                boolean bs = ms.matches();
                if (bs == false) {
                    if (ErrorMessage.contains("invalid"))
                        ErrorMessage = ErrorMessage + "state,";
                    else
                        ErrorMessage = ErrorMessage + "invalid state,";

                }

you can use the DomDocument method to get an individual HTML tag level variable too

$homepage = file_get_contents('https://www.example.com/');
$doc = new DOMDocument;
$doc->loadHTML($homepage);
$titles = $doc->getElementsByTagName('h3');
echo $titles->item(0)->nodeValue;

If you cannot set the width, then that means the width will change as the text gets bold. There is no way to avoid this, except by compromises such as modifying the padding/margins for each state.

As suggested by Adam Miller in the comments, I'll add another solution.

The MailMessage(String from, String to) constructor accepts a comma separated list of addresses. So if you happen to have already a comma (',') separated list, the usage is as simple as:

MailMessage Msg = new MailMessage(fromMail, addresses);

In this particular case, we can replace the ';' for ',' and still make use of the constructor.

MailMessage Msg = new MailMessage(fromMail, addresses.replace(";", ","));

Whether you prefer this or the accepted answer it's up to you. Arguably the loop makes the intent clearer, but this is shorter and not obscure. But should you already have a comma separated list, I think this is the way to go.

Trick to update props if they are array :

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  Text,
  View,
  Button
} from 'react-native';

class Counter extends Component {
  constructor(props) {
    super(props);
      this.state = {
        count: this.props.count
      }
    }
  increment(){
    console.log("this.props.count");
    console.log(this.props.count);
    let count = this.state.count
    count.push("new element");
    this.setState({ count: count})
  }
  render() {

    return (
      <View style={styles.container}>
        <Text>{ this.state.count.length }</Text>
        <Button
          onPress={this.increment.bind(this)}
          title={ "Increase" }
        />
      </View>
    );
  }
}

Counter.defaultProps = {
 count: []
}

export default Counter
const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
  },
  welcome: {
    fontSize: 20,
    textAlign: 'center',
    margin: 10,
  },
  instructions: {
    textAlign: 'center',
    color: '#333333',
    marginBottom: 5,
  },
});

This solution will work regardless of the number of char variables you have:

char c1 = 'z';
char c2 = 'w';
std::string s1{c1};
std::string s12{c1, c2};

You shall pass a this pointer to tell the function which object to work on because it relies on that as opposed to a static member function.

Here is my solution for Keyboard dismissing and scrolling to tapped TextInput (I am using ScrollView with keyboardDismissMode prop):

import React from 'react';
import {
  Platform,
  KeyboardAvoidingView,
  ScrollView
} from 'react-native';

const DismissKeyboard = ({ children }) => {
  const isAndroid = Platform.OS === 'android';
  const behavior = isAndroid ? false : 'padding';

  return (
    <KeyboardAvoidingView
      enabled
      behavior={ behavior }
      style={{ flex: 1}}
    >
      <ScrollView
        keyboardShouldPersistTaps={'always'}
        keyboardDismissMode={'on-drag'}
      >
        { children }
      </ScrollView>
    </KeyboardAvoidingView>
  );
};

export default DismissKeyboard;

usage:

render(){
   return(
     <DismissKeyboard>
       <TextInput
        style={{height: 40, borderColor: 'gray', borderWidth: 1}}
        onChangeText={(text) => this.setState({text})}
        value={this.state.text}
      />
     </DismissKeyboard>
   );
}

I spent a lot of time looking for a solution to this problem too. Here's what i've found thus far:

If you want your users to be able to click on a button and copy some text, you may have to use Flash.

If you want your users to press Ctrl+C anywhere on the page, but always copy xyz to the clipboard, I wrote an all-JS solution in YUI3 (although it could easily be ported to other frameworks, or raw JS if you're feeling particularly self-loathing).

It involves creating a textbox off the screen which gets highlighted as soon as the user hits Ctrl/CMD. When they hit 'C' shortly after, they copy the hidden text. If they hit 'V', they get redirected to a container (of your choice) before the paste event fires.

This method can work well, because while you listen for the Ctrl/CMD keydown anywhere in the body, the 'A', 'C' or 'V' keydown listeners only attach to the hidden text box (and not the whole body). It also doesn't have to break the users expectations - you only get redirected to the hidden box if you had nothing selected to copy anyway!

Here's what i've got working on my site, but check http://at.cg/js/clipboard.js for updates if there are any:

YUI.add('clipboard', function(Y) {


// Change this to the id of the text area you would like to always paste in to:

pasteBox = Y.one('#pasteDIV');


// Make a hidden textbox somewhere off the page.

Y.one('body').append('<input id="copyBox" type="text" name="result" style="position:fixed; top:-20%;" onkeyup="pasteBox.focus()">');
copyBox = Y.one('#copyBox');


// Key bindings for Ctrl+A, Ctrl+C, Ctrl+V, etc:

// Catch Ctrl/Window/Apple keydown anywhere on the page.
Y.on('key', function(e) {
    copyData();
        //  Uncomment below alert and remove keyCodes after 'down:' to figure out keyCodes for other buttons.
        //  alert(e.keyCode);
        //  }, 'body',  'down:', Y);
}, 'body',  'down:91,224,17', Y);

// Catch V - BUT ONLY WHEN PRESSED IN THE copyBox!!!
Y.on('key', function(e) {
    // Oh no! The user wants to paste, but their about to paste into the hidden #copyBox!!
    // Luckily, pastes happen on keyPress (which is why if you hold down the V you get lots of pastes), and we caught the V on keyDown (before keyPress).
    // Thus, if we're quick, we can redirect the user to the right box and they can unload their paste into the appropriate container. phew.
    pasteBox.select();
}, '#copyBox',  'down:86', Y);

// Catch A - BUT ONLY WHEN PRESSED IN THE copyBox!!!
Y.on('key', function(e) {
    // User wants to select all - but he/she is in the hidden #copyBox! That wont do.. select the pasteBox instead (which is probably where they wanted to be).
    pasteBox.select();

Two suggestions:

• Use a HashSet instead of an ArrayList. This will speed up the contains() checks considerably if you have a long list

• Make sure Customer.equals() and Customer.hashCode() are implemented properly, i.e. they should be based on the combined values of the underlying fields in the customer object.

It indicates that the VS Code file watcher is running out of handles because the workspace is large and contains many files. The max limit of watches has been reacherd, you can viewed the limit by running:

cat /proc/sys/fs/inotify/max_user_watches

run below code resolve this issue:

fs.inotify.max_user_watches=524288

setTimeout(callback,t) is used to run callback after at least t millisecond. The actual delay depends on many external factors like OS timer granularity and system load.

So, there is a possibility that it will be called slightly after the set time, but will never be called before.

A timer can't span more than 24.8 days.

In the MasterPage.cs file add the property of Label like this:

public string ErrorMessage
{
    get
    {
        return lblMessage.Text;
    }
    set
    {
        lblMessage.Text = value;
    }
}

On your aspx page, just below the Page Directive add this:

<%@ Page Title="" Language="C#" MasterPageFile="Master Path Name"..... %>
<%@ MasterType VirtualPath="Master Path Name" %>   // Add this

And in your codebehind(aspx.cs) page you can then easily access the Label Property and set its text as required. Like this:

this.Master.ErrorMessage = "Your Error Message here";

If you're interested in realtime plotting, I'd recommend looking into matplotlib's animation API. In particular, using blit to avoid redrawing the background on every frame can give you substantial speed gains (~10x):

#!/usr/bin/env python

import numpy as np
import time
import matplotlib
matplotlib.use('GTKAgg')
from matplotlib import pyplot as plt


def randomwalk(dims=(256, 256), n=20, sigma=5, alpha=0.95, seed=1):
    """ A simple random walk with memory """

    r, c = dims
    gen = np.random.RandomState(seed)
    pos = gen.rand(2, n) * ((r,), (c,))
    old_delta = gen.randn(2, n) * sigma

    while True:
        delta = (1. - alpha) * gen.randn(2, n) * sigma + alpha * old_delta
        pos += delta
        for ii in xrange(n):
            if not (0. <= pos[0, ii] < r):
                pos[0, ii] = abs(pos[0, ii] % r)
            if not (0. <= pos[1, ii] < c):
                pos[1, ii] = abs(pos[1, ii] % c)
        old_delta = delta
        yield pos


def run(niter=1000, doblit=True):
    """

    fig, ax = plt.subplots(1, 1)
    ax.set_aspect('equal')
    ax.set_xlim(0, 255)
    ax.set_ylim(0, 255)
    ax.hold(True)
    rw = randomwalk()
    x, y = rw.next()

    plt.show(False)
    plt.draw()

    if doblit:
        # cache the background
        background = fig.canvas.copy_from_bbox(ax.bbox)

    points = ax.plot(x, y, 'o')[0]
    tic = time.time()

    for ii in xrange(niter):

        # update the xy data
        x, y = rw.next()
        points.set_data(x, y)

            fig.canvas.restore_region(background)

            # redraw just the points
            ax.draw_artist(points)

            # fill in the axes rectangle
            fig.canvas.blit(ax.bbox)

        else:
            # redraw everything
            fig.canvas.draw()

    plt.close(fig)
    print "Blit = %s, average FPS: %.2f" % (
        str(doblit), niter / (time.time() - tic))

if __name__ == '__main__':
    run(doblit=False)
    run(doblit=True)

Output:

Blit = False, average FPS: 54.37
Blit = True, average FPS: 438.27

Joins can only be used when there is an association between entities. Your Employee entity should not have a field named id_team, of type int, mapped to a column. It should have a ManyToOne association with the Team entity, mapped as a JoinColumn:

@ManyToOne
@JoinColumn(name="ID_TEAM")
private Team team;

Then, the following query will work flawlessly:

select e from Employee e inner join e.team

Which will load all the employees, except those that aren't associated to any team.

The same goes for all the other fields which are a foreign key to some other table mapped as an entity, of course (id_boss, id_profession).

It's time for you to read the Hibernate documentation, because you missed an extremely important part of what it is and how it works.

Here is a solution with an stdout redirection:

def elevate():
    import ctypes, win32com.shell.shell, win32event, win32process
    outpath = r'%s\%s.out' % (os.environ["TEMP"], os.path.basename(__file__))
    if ctypes.windll.shell32.IsUserAnAdmin():
        if os.path.isfile(outpath):
            sys.stderr = sys.stdout = open(outpath, 'w', 0)
        return
    with open(outpath, 'w+', 0) as outfile:
        hProc = win32com.shell.shell.ShellExecuteEx(lpFile=sys.executable, \
            lpVerb='runas', lpParameters=' '.join(sys.argv), fMask=64, nShow=0)['hProcess']
        while True:
            hr = win32event.WaitForSingleObject(hProc, 40)
            while True:
                line = outfile.readline()
                if not line: break
                sys.stdout.write(line)
            if hr != 0x102: break
    os.remove(outpath)
    sys.stderr = ''
    sys.exit(win32process.GetExitCodeProcess(hProc))

if __name__ == '__main__':
    elevate()
    main()

just to add some clarity, you need to stage changes with git add, then amend last commit:

git add /path/to/modified/files
git commit --amend --no-edit

This is especially useful for if you forgot to add some changes in last commit or when you want to add more changes without creating new commits by reusing the last commit.

Today things have changed a little.

Now we avoid use ProgressDialog to show spinning progress:

If you want to put in your app a spinning progress you should use an Activity indicators:

http://developer.android.com/design/building-blocks/progress.html#activity

You can't wait() on an object unless the current thread owns that object's monitor. To do that, you must synchronize on it:

class Runner implements Runnable
{
  public void run()
  {
    try
    {
      synchronized(Main.main) {
        Main.main.wait();
      }
    } catch (InterruptedException e) {}
    System.out.println("Runner away!");
  }
}

The same rule applies to notify()/notifyAll() as well.

The Javadocs for wait() mention this:

This method should only be called by a thread that is the owner of this object's monitor. See the notify method for a description of the ways in which a thread can become the owner of a monitor.

Throws:

IllegalMonitorStateException – if the current thread is not the owner of this object's monitor.

And from notify():

A thread becomes the owner of the object's monitor in one of three ways:

• By executing a synchronized instance method of that object.
• By executing the body of a synchronized statement that synchronizes on the object.
• For objects of type Class, by executing a synchronized static method of that class.

In order to solve it you need to add async defer to the script.

It should be like this:

<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap"
    async defer></script>

See here the meaning of async defer.

Since you'll be calling a function from the main js file, you also want to make sure that this is after the one where you load the main script.

Another simple solution, in windows, go to the file Homestead/Vagrantfile and add these lines to connect with a username/password instead of a private key:

config.ssh.username = "vagrant"  
config.ssh.password = "vagrant"  
config.ssh.insert_key = false 

So, finally part of the file will look like this :

if File.exists? homesteadYamlPath then
    settings = YAML::load(File.read(homesteadYamlPath))
elsif File.exists? homesteadJsonPath then
    settings = JSON.parse(File.read(homesteadJsonPath))
end

config.ssh.username = "vagrant"  
config.ssh.password = "vagrant"  
config.ssh.insert_key = false 

Homestead.configure(config, settings)

if File.exists? afterScriptPath then
    config.vm.provision "shell", path: afterScriptPath, privileged: false
end

Hope this help ..

Expanding upon the above code from @dreamlax

char *readFile(char *fileName) {
    FILE *file = fopen(fileName, "r");
    char *code;
    size_t n = 0;
    int c;

    if (file == NULL) return NULL; //could not open file
    fseek(file, 0, SEEK_END);
    long f_size = ftell(file);
    fseek(file, 0, SEEK_SET);
    code = malloc(f_size);

    while ((c = fgetc(file)) != EOF) {
        code[n++] = (char)c;
    }

    code[n] = '\0';        

    return code;
}

This gives you the length of the file, then proceeds to read it character by character.

This is a super old thread but since the answer even says "It doesn't make any sense", I thought I'd add the answer...

The original post used $(this).remove(); in the close handler, this would actually remove the dialog div from the DOM. Attempting to initialize a dialog again wouldn't work because the div was removed.

Using $(this).dialog('destroy') is calling the method destroy defined in the dialog object which does not remove it from the DOM.

From the documentation:

destroy()

Removes the dialog functionality completely. This will return the element back to its >>pre-init state. This method does not accept any arguments.

That said, only destroy or remove on close if you have a good reason to.

A little more pythonic way I think would be:

timestr = '00:04:23'

ftr = [3600,60,1]

sum([a*b for a,b in zip(ftr, map(int,timestr.split(':')))])

Output is 263Sec.

I would be interested to see if anyone could simplify it further.

No need to used grep here, Try this:

df . -B MB | tail -1 | awk {'print substr($5, 1, length($5)-1)'}

Have you tried with prop() ??

Well prop() seems works for me.

I know it's old post, but I thought this is a good addition: You can use List<T>.ConvertAll<TOutput>

List<int> integers = strings.ConvertAll(s => Int32.Parse(s));

The "parameter is not valid" exception thrown by Image.FromStream() tells you that the stream is not a 'valid' or 'recognised' format. Watch the memory streams, especially if you are taking various offsets of bytes from a file.

// 1. Create a junk memory stream, pass it to Image.FromStream and 
// get the "parameter is not valid":
MemoryStream ms = new MemoryStream(new Byte[] {0x00, 0x01, 0x02});
System.Drawing.Image returnImage = System.Drawing.Image.FromStream(ms);`

// 2. Create a junk memory stream, pass it to Image.FromStream
// without verification:
MemoryStream ms = new MemoryStream(new Byte[] {0x00, 0x01, 0x02});
System.Drawing.Image returnImage = System.Drawing.Image.FromStream(ms, false, true);

Example 2 will work, note that useEmbeddedColorManagement must be false for validateImageData to be valid.

May be easiest to debug by dumping the memory stream to a file and inspecting the content.

The best solution is to use:

domElement.click()

Because the angularjs triggerHandler(angular.element(domElement).triggerHandler('click')) click events does not bubble up in the DOM hierarchy, but the one above does - just like a normal mouse click.

https://docs.angularjs.org/api/ng/function/angular.element

http://api.jquery.com/triggerhandler/

https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/click

Any collection that you iterate over with foreach may not be modified during iteration.

So while you're running a foreach over rankings, you cannot modify its elements, add new ones or delete any.

Here is how to make an authenticated POST request, using Refinery as an example:

# Start Rails console
rails console
# Get the login form
app.get '/community_members/sign_in'
# View the session
app.session.to_hash
# Copy the CSRF token "_csrf_token" and place it in the login request.
# Log in from the console to create a session
app.post '/community_members/login', {"authenticity_token"=>"gT7G17RNFaWUDLC6PJGapwHk/OEyYfI1V8yrlg0lHpM=",  "refinery_user[login]"=>'chloe', 'refinery_user[password]'=>'test'}
# View the session to verify CSRF token is the same
app.session.to_hash
# Copy the CSRF token "_csrf_token" and place it in the request. It's best to edit this in Notepad++
app.post '/refinery/blog/posts', {"authenticity_token"=>"gT7G17RNFaWUDLC6PJGapwHk/OEyYfI1V8yrlg0lHpM=", "switch_locale"=>"en", "post"=>{"title"=>"Test", "homepage"=>"0", "featured"=>"0", "magazine"=>"0", "refinery_category_ids"=>["1282"], "body"=>"Tests do a body good.", "custom_teaser"=>"", "draft"=>"0", "tag_list"=>"", "published_at(1i)"=>"2014", "published_at(2i)"=>"5", "published_at(3i)"=>"27", "published_at(4i)"=>"21", "published_at(5i)"=>"20", "custom_url"=>"", "source_url_title"=>"", "source_url"=>"", "user_id"=>"56", "browser_title"=>"", "meta_description"=>""}, "continue_editing"=>"false", "locale"=>:en}

You might find these useful too if you get an error:

app.cookies.to_hash
app.flash.to_hash
app.response # long, raw, HTML

I would like to offer a generalized example for a very similar use case:

Use Case: I have a csv consisting of:

First|Third|Fifth
data|data|data
data|data|data
...billion more lines

I need to perform some transformations and the final csv needs to look like

First|Second|Third|Fourth|Fifth
data|null|data|null|data
data|null|data|null|data
...billion more lines

I need to do this because this is the schema defined by some model and I need for my final data to be interoperable with SQL Bulk Inserts and such things.

so:

1) I read the original csv using spark.read and call it "df".

2) I do something to the data.

3) I add the null columns using this script:

outcols = []
for column in MY_COLUMN_LIST:
    if column in df.columns:
        outcols.append(column)
    else:
        outcols.append(lit(None).cast(StringType()).alias('{0}'.format(column)))

df = df.select(outcols)

In this way, you can structure your schema after loading a csv (would also work for reordering columns if you have to do this for many tables).

The docs for Google Test 1.7 suggest:

"If you have a broken test that you cannot fix right away, you can add the DISABLED_ prefix to its name. This will exclude it from execution."

Examples:

// Tests that Foo does Abc.
TEST(FooTest, DISABLED_DoesAbc) { ... }

class DISABLED_BarTest : public ::testing::Test { ... };

// Tests that Bar does Xyz.
TEST_F(DISABLED_BarTest, DoesXyz) { ... }

If you already know the process then this will be useful:

PID=`ps -eaf | grep <process> | grep -v grep | awk '{print $2}'`
if [[ "" !=  "$PID" ]]; then
echo "killing $PID"
kill -9 $PID
fi

This method will create a copy of your list but your type should be serializable.

Use:

List<Student> lstStudent = db.Students.Where(s => s.DOB < DateTime.Now).ToList().CopyList(); 

Method:

public static List<T> CopyList<T>(this List<T> lst)
    {
        List<T> lstCopy = new List<T>();
        foreach (var item in lst)
        {
            using (MemoryStream stream = new MemoryStream())
            {
                BinaryFormatter formatter = new BinaryFormatter();
                formatter.Serialize(stream, item);
                stream.Position = 0;
                lstCopy.Add((T)formatter.Deserialize(stream));
            }
        }
        return lstCopy;
    }

I had similiar issue but only with Chrome, Firefox was working. I noticed that Chrome was adding an Origin parameter in the header request.

So in my nginx.conf I added the parameter to avoid it under location/ block

proxy_set_header Origin "";

As what has already been mentioned by others, what behind the mystery is Branch Predictor.

I'm not trying to add something but explaining the concept in another way. There is a concise introduction on the wiki which contains text and diagram. I do like the explanation below which uses a diagram to elaborate the Branch Predictor intuitively.

In computer architecture, a branch predictor is a digital circuit that tries to guess which way a branch (e.g. an if-then-else structure) will go before this is known for sure. The purpose of the branch predictor is to improve the flow in the instruction pipeline. Branch predictors play a critical role in achieving high effective performance in many modern pipelined microprocessor architectures such as x86.

Two-way branching is usually implemented with a conditional jump instruction. A conditional jump can either be "not taken" and continue execution with the first branch of code which follows immediately after the conditional jump, or it can be "taken" and jump to a different place in program memory where the second branch of code is stored. It is not known for certain whether a conditional jump will be taken or not taken until the condition has been calculated and the conditional jump has passed the execution stage in the instruction pipeline (see fig. 1).

Based on the described scenario, I have written an animation demo to show how instructions are executed in a pipeline in different situations.

1. Without the Branch Predictor.

Without branch prediction, the processor would have to wait until the conditional jump instruction has passed the execute stage before the next instruction can enter the fetch stage in the pipeline.

The example contains three instructions and the first one is a conditional jump instruction. The latter two instructions can go into the pipeline until the conditional jump instruction is executed.

It will take 9 clock cycles for 3 instructions to be completed.

2. Use Branch Predictor and don't take a conditional jump. Let's assume that the predict is not taking the conditional jump.

It will take 7 clock cycles for 3 instructions to be completed.

3. Use Branch Predictor and take a conditional jump. Let's assume that the predict is not taking the conditional jump.

It will take 9 clock cycles for 3 instructions to be completed.

The time that is wasted in case of a branch misprediction is equal to the number of stages in the pipeline from the fetch stage to the execute stage. Modern microprocessors tend to have quite long pipelines so that the misprediction delay is between 10 and 20 clock cycles. As a result, making a pipeline longer increases the need for a more advanced branch predictor.

As you can see, it seems we don't have a reason not to use Branch Predictor.

It's quite a simple demo that clarifies the very basic part of Branch Predictor. If those gifs are annoying, please feel free to remove them from the answer and visitors can also get the live demo source code from BranchPredictorDemo

In Angular 6, you can do this:

In your service file:

 function_name(data) {
    const url = `the_URL`;
    let input = new FormData();
    input.append('url', data);   // "url" as the key and "data" as value
    return this.http.post(url, input).pipe(map((resp: any) => resp));
  }

In component.ts file: in any function say xyz,

xyz(){
this.Your_service_alias.function_name(data).subscribe(d => {   // "data" can be your file or image in base64 or other encoding
      console.log(d);
    });
}

Also making the values categorical and calling summary() would work.

> v = rep(as.factor(c(1,2, 2, 2)), 25)
> summary(v)
 1  2 
25 75 

__FILE__ is the filename with extension of the file containing the code being executed.

In foo.rb, __FILE__ would be "foo.rb".

If foo.rb were in the dir /home/josh then File.dirname(__FILE__) would return /home/josh.

I'm still having problems figuring out exactly how I find out what a user is typing into a ckeditor textarea.

Ok, this is fairly easy. Assuming your editor is named "editor1", this will give you an alert with your its contents:

alert(CKEDITOR.instances.editor1.getData());

The harder part is detecting when the user types. From what I can tell, there isn't actually support to do that (and I'm not too impressed with the documentation btw). See this article: http://alfonsoml.blogspot.com/2011/03/onchange-event-for-ckeditor.html

Instead, I would suggest setting a timer that is going to continuously update your second div with the value of the textarea:

timer = setInterval(updateDiv,100);
function updateDiv(){
    var editorText = CKEDITOR.instances.editor1.getData();
    $('#trackingDiv').html(editorText);
}

This seems to work just fine. Here's the entire thing for clarity:

<textarea id="editor1" name="editor1">This is sample text</textarea>

<div id="trackingDiv" ></div>

<script type="text/javascript">
    CKEDITOR.replace( 'editor1' );

    timer = setInterval(updateDiv,100);
    function updateDiv(){
        var editorText = CKEDITOR.instances.editor1.getData();
        $('#trackingDiv').html(editorText);
    }
</script>

tcptraceroute   xx.xx.xx.xx 9100

if you didn't find it you can install it

yum -y install tcptraceroute 

or

aptitude -y install tcptraceroute 

Try (bonus)

let hex2rgb= c=> `rgb(${c.substr(1).match(/../g).map(x=>+`0x${x}`)})`;
let rgb2hex= c=>'#'+c.match(/\d+/g).map(x=>(+x).toString(16).padStart(2,0)).join``

let hex2rgb= c=> `rgb(${c.substr(1).match(/../g).map(x=>+`0x${x}`)})`;
let rgb2hex= c=> '#'+c.match(/\d+/g).map(x=>(+x).toString(16).padStart(2,0)).join``;

// TEST
console.log('#0080C0          -->', hex2rgb('#0080C0'));
console.log('rgb(0, 128, 192) -->', rgb2hex('rgb(0, 128, 192)'));

This will work

all = [a1, b1, b2, a2,.....]

map(lambda x: x.start(),all)    

simple example

all = ["MILK","BREAD","EGGS"]
map(lambda x:x.lower(),all)
>>>['milk','bread','eggs']

and in python3

all = ["MILK","BREAD","EGGS"]
list(map(lambda x:x.lower(),all))
>>>['milk','bread','eggs']

@rvighne solution works well, but as identified in the comments ParentElement and ClassList both have compatibility issues. To make it more compatible, I have used:

function findAncestor (el, cls) {
    while ((el = el.parentNode) && el.className.indexOf(cls) < 0);
    return el;
}

• parentNode property instead of the parentElement property
• indexOf method on the className property instead of the contains method on the classList property.

Of course, indexOf is simply looking for the presence of that string, it does not care if it is the whole string or not. So if you had another element with class 'ancestor-type' it would still return as having found 'ancestor', if this is a problem for you, perhaps you can use regexp to find an exact match.

If it writes that you had not properly shut down or that mongod.lock is not empty , only delete mongod.lock from C:\data\db\ and it will start.

A supplemental visual view of pd.concat([df0, df1], kwargs). Notice that, kwarg axis=0 or axis=1 's meaning is not as intuitive as df.mean() or df.apply(func)

Or you can encapsulate the looping logic itself in a try catch e.g.

for(int i = function2(); i < 100 /*where 100 is the end or another function call to get the end*/; i = function2()){

    try{
     //ToDo
    }
    catch { continue; }    

}

Or...

try{ 
    for(int i = function2(); ; ;) {
        try { i = function2(); return; } 
        finally { /*decide to break or not :P*/continue; } }
} catch { /*failed on first try*/ } finally{ /*afterwardz*/ }

you can use CHARINDEX in t-sql.

select * from table where CHARINDEX(url, 'http://url.com/url?url...') > 0

Interfaces specify behavior of an object.

Static methods do not specify a behavior of an object, but behavior that affects an object in some way.

queryParams

queryParams is another input of routerLink where they can be passed like

<a [routerLink]="['../']" [queryParams]="{prop: 'xxx'}">Somewhere</a>

fragment

<a [routerLink]="['../']" [queryParams]="{prop: 'xxx'}" [fragment]="yyy">Somewhere</a>

routerLinkActiveOptions

To also get routes active class set on parent routes:

[routerLinkActiveOptions]="{ exact: false }"

To pass query parameters to this.router.navigate(...) use

let navigationExtras: NavigationExtras = {
  queryParams: { 'session_id': sessionId },
  fragment: 'anchor'
};

// Navigate to the login page with extras
this.router.navigate(['/login'], navigationExtras);

This answer is in three parts, see below for the official release (v3 and v4)

I couldn't even find the col-lg-push-x or pull classes in the original files for RC1 i downloaded, so check your bootstrap.css file. hopefully this is something they will sort out in RC2.

anyways, the col-push-* and pull classes did exist and this will suit your needs. Here is a demo

<div class="row">
    <div class="col-sm-5 col-push-5">
        Content B
    </div>
    <div class="col-sm-5 col-pull-5">
        Content A
    </div>
    <div class="col-sm-2">
        Content C
    </div>
</div>

EDIT: BELOW IS THE ANSWER FOR THE OFFICIAL RELEASE v3.0

Also see This blog post on the subject

• col-vp-push-x = push the column to the right by x number of columns, starting from where the column would normally render -> position: relative, on a vp or larger view-port.

• col-vp-pull-x = pull the column to the left by x number of columns, starting from where the column would normally render -> position: relative, on a vp or larger view-port.

  vp = xs, sm, md, or lg

  x = 1 thru 12

I think what messes most people up, is that you need to change the order of the columns in your HTML markup (in the example below, B comes before A), and that it only does the pushing or pulling on view-ports that are greater than or equal to what was specified. i.e. col-sm-push-5 will only push 5 columns on sm view-ports or greater. This is because Bootstrap is a "mobile first" framework, so your HTML should reflect the mobile version of your site. The Pushing and Pulling are then done on the larger screens.

• (Desktop) Larger view-ports get pushed and pulled.
• (Mobile) Smaller view-ports render in normal order.

DEMO

<div class="row">
    <div class="col-sm-5 col-sm-push-5">
        Content B
    </div>
    <div class="col-sm-5 col-sm-pull-5">
        Content A
    </div>
    <div class="col-sm-2">
        Content C
    </div>
</div>

View-port >= sm

|A|B|C|

View-port < sm

|B|
|A|
|C|

EDIT: BELOW IS THE ANSWER FOR v4.0

With v4 comes flexbox and other changes to the grid system and the push\pull classes have been removed in favor of using flexbox ordering.

• Use .order-* classes to control visual order (where * = 1 thru 12)
• This can also be grid tier specific .order-md-*
• Also .order-first (-1) and .order-last (13) avalable

<div class="row">_x000D_
  <div class="col order-2">1st yet 2nd</div>_x000D_
  <div class="col order-1">2nd yet 1st</div>_x000D_
</div>

To obtain a stream of just the names:

$ jq '.[] | select(.location=="Stockholm") | .name' json

produces:

"Donald"
"Walt"

To obtain a stream of corresponding (key name, "name" attribute) pairs, consider:

$ jq -c 'to_entries[]
        | select (.value.location == "Stockholm")
        | [.key, .value.name]' json

Output:

["FOO","Donald"]
["BAR","Walt"]

There's an overload of String.Split for this:

"THExxQUICKxxBROWNxxFOX".Split(new [] {"xx"}, StringSplitOptions.None);

l = []
x = 0
l.extend([x]*100)

This is a short and crisp answer to your problem:

from __future__ import print_function
import MySQLdb
import numpy as np
import pandas as pd
import xlrd

# Connecting to MySQL Database
connection = MySQLdb.connect(
             host="hostname",
             port=0000,
             user="userID",
             passwd="password",
             db="table_documents",
             charset='utf8'
           )
print(connection)
#getting data from database into a dataframe
sql_for_df = 'select * from tabledata'
df_from_database = pd.read_sql(sql_for_df , connection)

Consider below 2 tables:

EMP

empid   name    dept_id salary
1       Rob     1       100
2       Mark    1       300
3       John    2       100
4       Mary    2       300
5       Bill    3       700
6       Jose    6       400

Department

deptid  name
1       IT
2       Accounts
3       Security
4       HR
5       R&D

Inner Join:

Mostly written as just JOIN in sql queries. It returns only the matching records between the tables.

Find out all employees and their department names:

Select a.empid, a.name, b.name as dept_name
FROM emp a
JOIN department b
ON a.dept_id = b.deptid
;

empid   name    dept_name
1       Rob     IT
2       Mark    IT
3       John    Accounts
4       Mary    Accounts
5       Bill    Security

As you see above, Jose is not printed from EMP in the output as it's dept_id 6 does not find a match in the Department table. Similarly, HR and R&D rows are not printed from Department table as they didn't find a match in the Emp table.

So, INNER JOIN or just JOIN, returns only matching rows.

LEFT JOIN :

This returns all records from the LEFT table and only matching records from the RIGHT table.

Select a.empid, a.name, b.name as dept_name
FROM emp a
LEFT JOIN department b
ON a.dept_id = b.deptid
;

empid   name    dept_name
1       Rob     IT
2       Mark    IT
3       John    Accounts
4       Mary    Accounts
5       Bill    Security
6       Jose    

So, if you observe the above output, all records from the LEFT table(Emp) are printed with just matching records from RIGHT table.

HR and R&D rows are not printed from Department table as they didn't find a match in the Emp table on dept_id.

So, LEFT JOIN returns ALL rows from Left table and only matching rows from RIGHT table.

Use the alternate value for animation-direction (and you don't need to add any keframes this way).

alternate

The animation should reverse direction each cycle. When playing in reverse, the animation steps are performed backward. In addition, timing functions are also reversed; for example, an ease-in animation is replaced with an ease-out animation when played in reverse. The count to determinate if it is an even or an odd iteration starts at one.

CSS:

.waitingForConnection {
  animation: blinker 1.7s cubic-bezier(.5, 0, 1, 1) infinite alternate;  
}
@keyframes blinker { to { opacity: 0; } }

I've removed the from keyframe. If it's missing, it gets generated from the value you've set for the animated property (opacity in this case) on the element, or if you haven't set it (and you haven't in this case), from the default value (which is 1 for opacity).

And please don't use just the WebKit version. Add the unprefixed one after it as well. If you just want to write less code, use the shorthand.

.waitingForConnection {
  animation: blinker 1.7s cubic-bezier(.5, 0, 1, 1) infinite alternate;  
}
@keyframes blinker { to { opacity: 0; } }

.waitingForConnection2 {
  animation: blinker2 0.6s cubic-bezier(1, 0, 0, 1) infinite alternate;  
}
@keyframes blinker2 { to { opacity: 0; } }

.waitingForConnection3 {
  animation: blinker3 1s ease-in-out infinite alternate;  
}
@keyframes blinker3 { to { opacity: 0; } }

<div class="waitingForConnection">X</div>
<div class="waitingForConnection2">Y</div>
<div class="waitingForConnection3">Z</div>

def index(arr, num):
    for i, x in enumerate(arr):
        if x == num:
            print(x, i)

#index(List, 'A')

I always use my own mod function, defined as

int mod(int x, int m) {
    return (x%m + m)%m;
}

Of course, if you're bothered about having two calls to the modulus operation, you could write it as

int mod(int x, int m) {
    int r = x%m;
    return r<0 ? r+m : r;
}

or variants thereof.

The reason it works is that "x%m" is always in the range [-m+1, m-1]. So if at all it is negative, adding m to it will put it in the positive range without changing its value modulo m.

You have to put your main queue dispatching in the block that runs the computation. For example (here I create a dispatch queue and don't use a global one):

dispatch_queue_t queue = dispatch_queue_create("com.example.MyQueue", NULL);
dispatch_async(queue, ^{
  // Do some computation here.

  // Update UI after computation.
  dispatch_async(dispatch_get_main_queue(), ^{
    // Update the UI on the main thread.
  });
});

Of course, if you create a queue don't forget to dispatch_release if you're targeting an iOS version before 6.0.

Perhaps an example will help:

git rm --cached asd
git commit -m "the file asd is gone from the repository"

versus

git reset HEAD -- asd
git commit -m "the file asd remains in the repository"

Note that if you haven't changed anything else, the second commit won't actually do anything.

REST is tightly coupled with HTTP, so if you only expose your API over HTTP then REST is more appropriate for most (but not all) situations. However, if you need to expose your API over other transports like messaging or web sockets then REST is just not applicable.

... you can use it on any granularity type i.e.:

DATEPART(YEAR, [date])

DATEPART(MONTH, [date]) 

DATEPART(DAY, [date])    

DATEPART(HOUR, [date]) 

DATEPART(MINUTE, [date])

(note: I like the [ ] around the date reserved word though. Of course that's in case your column with timestamp is labeled "date")

I know the question is really old, but with generics one can add a more generalized method with will work for all types.

public static <T> T getValueOrDefault(T value, T defaultValue) {
    return value == null ? defaultValue : value;
}

Take a look in .git/config and make the changes you need.

Alternatively you could use

git remote rm [name of the url you sets on adding]

and

git remote add [name] [URL]

Or just

git remote set-url [URL]

Before you do anything wrong, double check with

git help remote

table {
    border-spacing: 4px; 
    color: #000; 
    background: #ccc;

Open $CATALINA_BASE/conf/web.xml and find this

<!-- ==================== Default Session Configuration ================= -->
<!-- You can set the default session timeout (in minutes) for all newly   -->
<!-- created sessions by modifying the value below.                       -->

<session-config>
  <session-timeout>30</session-timeout>
</session-config>

all webapps implicitly inherit from this default web descriptor. You can override session-config as well as other settings defined there in your web.xml.

This is actually from my Tomcat 7 (Windows) but I think 5.5 conf is not very different

This should work with any div or screen size:

.center-screen {_x000D_
  display: flex;_x000D_
  flex-direction: column;_x000D_
  justify-content: center;_x000D_
  align-items: center;_x000D_
  text-align: center;_x000D_
  min-height: 100vh;_x000D_
}

 <html>_x000D_
 <head>_x000D_
 </head>_x000D_
 <body>_x000D_
 <div class="center-screen">_x000D_
 I'm in the center_x000D_
 </div>_x000D_
 </body>_x000D_
 </html>

See more details about flex here. This should work on most of the browsers, see compatibility matrix here.

Update: If you don't want the scroll bar, make min-height smaller, for example min-height: 95vh;

I would try what Logan and 1mdm suggested, tho tweak the CSS, but I would really wait for a new Chrome version to come out with fixed bugs, before growing white hair.

IMHO the current Chrome version is still alpha version and was released so that it can spread while it is in development. I personally had issues with table widths, my code worked fine in EVERY browser but could not make it work in Chrome.

A URL that was created from a JavaScript Blob can not be converted to a "normal" URL.

A blob: URL does not refer to data the exists on the server, it refers to data that your browser currently has in memory, for the current page. It will not be available on other pages, it will not be available in other browsers, and it will not be available from other computers.

Therefore it does not make sense, in general, to convert a Blob URL to a "normal" URL. If you wanted an ordinary URL, you would have to send the data from the browser to a server and have the server make it available like an ordinary file.

It is possible convert a blob: URL into a data: URL, at least in Chrome. You can use an AJAX request to "fetch" the data from the blob: URL (even though it's really just pulling it out of your browser's memory, not making an HTTP request).

Here's an example:

var blob = new Blob(["Hello, world!"], { type: 'text/plain' });_x000D_
var blobUrl = URL.createObjectURL(blob);_x000D_
_x000D_
var xhr = new XMLHttpRequest;_x000D_
xhr.responseType = 'blob';_x000D_
_x000D_
xhr.onload = function() {_x000D_
   var recoveredBlob = xhr.response;_x000D_
_x000D_
   var reader = new FileReader;_x000D_
_x000D_
   reader.onload = function() {_x000D_
     var blobAsDataUrl = reader.result;_x000D_
     window.location = blobAsDataUrl;_x000D_
   };_x000D_
_x000D_
   reader.readAsDataURL(recoveredBlob);_x000D_
};_x000D_
_x000D_
xhr.open('GET', blobUrl);_x000D_
xhr.send();

data: URLs are probably not what you mean by "normal" and can be problematically large. However they do work like normal URLs in that they can be shared; they're not specific to the current browser or session.

in javascript, object properties can be accessed with . operator or with associative array indexing using []. ie. object.property is equivalent to object["property"]

this should do the trick

var smth = mydata.list[0]["points.bean.pointsBase"][0].time;

public float getMesureLatLang(double lat,double lang) {

    Location loc1 = new Location("");
    loc1.setLatitude(getLatitute());// current latitude
    loc1.setLongitude(getLangitute());//current  Longitude

    Location loc2 = new Location("");
    loc2.setLatitude(lat);
    loc2.setLongitude(lang);

    return loc1.distanceTo(loc2);
 //  return distance(getLatitute(),getLangitute(),lat,lang);
}

What is the right approach for doing this?

There are a lot of "right" approaches, you just have decide which one best suites your needs. It appears as though you're misunderstanding how to use node_modules...

If you're familiar with NuGet you should think of npm as its client-side counterpart. Where the node_modules directory is like the bin directory for NuGet. The idea is that this directory is just a common location for storing packages, in my opinion it is better to take a dependency on the packages you need as you have done in the package.json. Then use a task runner like Gulp for example to copy the files you need into your desired wwwroot location.

I wrote a blog post about this back in January that details npm, Gulp and a whole bunch of other details that are still relevant today. Additionally, someone called attention to my SO question I asked and ultimately answered myself here, which is probably helpful.

I created a Gist that shows the gulpfile.js as an example.

In your Startup.cs it is still important to use static files:

app.UseStaticFiles();

This will ensure that your application can access what it needs.

I know it's late, but i hope someone will be helped of this answer

INSERT INTO t1 (a,b,c) VALUES (1,2,3),(4,5,6)
ON DUPLICATE KEY UPDATE c=VALUES(a)+VALUES(b);

You can read the tutorial below here :

https://mariadb.com/kb/en/library/insert-on-duplicate-key-update/

http://www.mysqltutorial.org/mysql-insert-or-update-on-duplicate-key-update/

In file php.ini you should try this for all errors:

display_errors = On

Location file is:

• Ubuntu 16.04:/etc/php/7.0/apache2
• CentOS 7:/etc/php.ini

Perhaps you want something like:

<style name="CustomActivityTheme" parent="@android:style/Theme.Holo">
    <item name="android:checkboxStyle">@style/customCheckBoxStyle</item>
</style>

<style name="customCheckBoxStyle" parent="@android:style/Widget.CompoundButton.CheckBox">
    <item name="android:textColor">@android:color/black</item>
</style>

Note, the textColor item.

git ignore is a convention in git. Setting a file by the name of .gitignore will ignore the files in that directory and deeper directories that match the patterns that the file contains. The most common use is just to have one file like this at the top level. But you can add others deeper in your directory structure to ignore even more patterns or stop ignoring them for that directory and subsequently deeper ones.

Likewise, you can "unignore" certain files in a deeper structure or a specific subset (ie, you ignore *.log but want to still track important.log) by specifying patterns beginning with !. eg:

*.log !important.log

will ignore all log files but will track files named important.log

If you are tracking files you meant to ignore, delete them, add the pattern to you .gitignore file and add all the changes

# delete files that should be ignored, or untrack them with 
# git rm --cached <file list or pattern>

# stage all the changes git commit
git add -A 

from now on your repository will not have them tracked.

If you would like to clean up your history, you can

# if you want to correct the last 10 commits
git rebase -i --preserve-merges HEAD~10 

then mark each commit with e or edit. Save the plan. Now git will replay your history stopping at each commit you marked with e. Here you delete the files you don't want, git add -A and then git rebase --continue until you are done. Your history will be clean. Make sure you tell you coworkers as you will have to force push and they will have to rebase what they didn't push yet.

I usually use Gloss library to serialize or deserialize JSON in iOS. For example, I have JSON that looks like this:

{"ABDC":[{"AB":"qwerty","CD":"uiop"}],[{"AB":"12334","CD":"asdf"}]}

First, I model the JSON array in Gloss struct:

Struct Struct_Name: Decodable {
   let IJ: String?
   let KL: String?
   init?(json: JSON){
       self.IJ = "AB" <~~ json
       self.KL = "CD" <~~ json
   }
}

And then in Alamofire responseJSON, I do this following thing:

Alamofire.request(url, method: .get, paramters: parametersURL).validate(contentType: ["application/json"]).responseJSON{ response in
 switch response.result{
   case .success (let data):
    guard let value = data as? JSON,
       let eventsArrayJSON = value["ABDC"] as? [JSON]
    else { fatalError() }
    let struct_name = [Struct_Name].from(jsonArray: eventsArrayJSON)//the JSON deserialization is done here, after this line you can do anything with your JSON
    for i in 0 ..< Int((struct_name?.count)!) {
       print((struct_name?[i].IJ!)!)
       print((struct_name?[i].KL!)!)
    }
    break

   case .failure(let error):
    print("Error: \(error)")
    break
 }
}

The output from the code above:

qwerty
uiop
1234
asdf

Having sequential ID's makes it a LOT easier for a hacker or data miner to compromise your site and data. Keep that in mind when choosing a PK for a website.

The quickest way would be with a pivot table. Make sure your column of data has a header row, highlight the data and the header, from the insert ribbon select pivot table and then drag your header from the pivot table fields list to the row labels and to the values boxes.

as to me in my directory I have multiple subdir, each subdir has lots of images I want to change all the subdir images to 1.jpg ~ n.jpg

def batch_rename():
    base_dir = 'F:/ad_samples/test_samples/'
    sub_dir_list = glob.glob(base_dir + '*')
    # print sub_dir_list # like that ['F:/dir1', 'F:/dir2']
    for dir_item in sub_dir_list:
        files = glob.glob(dir_item + '/*.jpg')
        i = 0
        for f in files:
            os.rename(f, os.path.join(dir_item, str(i) + '.jpg'))
            i += 1

This is very good question but not as wanting as question. There is difference between 'self' and 'cls' used method though analogically they are at same place

def moon(self, moon_name):
    self.MName = moon_name

#but here cls method its use is different 

@classmethod
def moon(cls, moon_name):
    instance = cls()
    instance.MName = moon_name

Now you can see both are moon function but one can be used inside class while other function name moon can be used for any class.

For practical programming approach :

While designing circle class we use area method as cls instead of self because we don't want area to be limited to particular class of circle only .

I had to do the same thing and this is what I wrote.I made it more flexible in my case as I had multiple group of check boxes to check.

// param: reqNum number of checkboxes to select
$.fn.checkboxValidate = function(reqNum){
    var fields = this.serializeArray();
    return (fields.length < reqNum) ? 'invalid' : 'valid';
}

then you can pass this function to check multiple group of checkboxes with multiple rules.

// helper function to create error
function err(msg){
    alert("Please select a " + msg + " preference.");
}

$('#reg').submit(function(e){
    //needs at lease 2 checkboxes to be selected
    if($("input.region, input.music").checkboxValidate(2) == 'invalid'){
        err("Region and Music");
    } 
});

You can do the same like this:

@Override
public FaqQuestions getFaqQuestionById(Long questionId) {
    session = sessionFactory.openSession();
    tx = session.beginTransaction();
    FaqQuestions faqQuestions = null;
    try {
        faqQuestions = (FaqQuestions) session.get(FaqQuestions.class,
                questionId);
        Hibernate.initialize(faqQuestions.getFaqAnswers());

        tx.commit();
        faqQuestions.getFaqAnswers().size();
    } finally {
        session.close();
    }
    return faqQuestions;
}

Just use faqQuestions.getFaqAnswers().size()nin your controller and you will get the size if lazily intialised list, without fetching the list itself.

I'd like to clarify one small gotcha here. You must use CustomVideoMode1 before CustomVideoMode2, etc. VirtualBox recognizes these modes in order starting from 1 and if you skip a number, it will not recognize anything at or beyond the number you skipped. This caught me by surprise.
