Insert date in the following format yyyy-MM-dd example,

INSERT INTO `PROGETTO`.`ALBERGO`(`ID`, `nome`, `viale`, `num_civico`, `data_apertura`, `data_chiusura`, `orario_apertura`, `orario_chiusura`, `posti_liberi`, `costo_intero`, `costo_ridotto`, `stelle`, `telefono`, `mail`, `web`, `Nome-paese`, `Comune`)

If you don't have double value field or data, maybe you should try to disable sql strict mode.

To do that you have to edit "my.ini" file located in MySQL installation folder, find "Set the SQL mode to strict" line and change the below line:

# Set the SQL mode to strict
sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

to this, deleting "STRICT_TRANS_TABLES"

# Set the SQL mode to strict
sql-mode="NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

After that, you have to restart MySQL service to enable this change.

To check the change, open the editor an execute this sql sentence:

SHOW VARIABLES LIKE 'sql_mode';

Very Important: Be careful of the file format after saving. Save it as "UTF8" and don't as "TFT8 with BOM" because the service will not restart.

I was having this same issue. I found out if you go to the Task in Task Scheduler that is running the powershell.exe script, you can click "Run whether user is logged on or not" and that will never show the powershell window when the task runs.

You are creating a Date object, which is a representation of a certain point in the timeline. This means that it will have all the parts necessary to represent it correctly, including minutes and seconds and so on. Because you initialize it from a string containing only a part of the date, the missing data will be defaulted.

I assume you are then "printing" this Date object, but without actually specifying a format like you did when parsing it. Use the same SimpleDateFormat but call the reverse method, format(Date) as Holger suggested

Use:

git remote add upstream ORIGINAL_REPOSITORY_URL

This will set your upstream to the repository you forked from. Then do this:

git fetch upstream      

This will fetch all the branches including master from the original repository.

Merge this data in your local master branch:

git merge upstream/master

Push the changes to your forked repository i.e. to origin:

git push origin master

Voila! You are done with the syncing the original repository.

You don't even need to nest the second relative layout inside the first one. Simply use the android:layout_alignParentBottom="true" in the Button and EditText.

naturalWidth and naturalHeight

var img = document.createElement("img");
img.onload = function (event)
{
    console.log("natural:", img.naturalWidth, img.naturalHeight);
    console.log("width,height:", img.width, img.height);
    console.log("offsetW,offsetH:", img.offsetWidth, img.offsetHeight);
}
img.src = "image.jpg";
document.body.appendChild(img);

// css for tests
img { width:50%;height:50%; }

Simple and fast since a 1d array is essentially a vector

vector <- array[1:length(array)]

I encountered a similar issue, I created a 'foo' folder and created a "class" inside foo, then I get the aforementioned error. One fix is to add "static" as earlier mentioned to the class which will be "public static class LinqHelper".

My assumption is that when you create a class inside the foo folder it regards it as an extension class, hence the following inter alia rule apply to it:

1) Every extension method must be a static method

WORKAROUND If you don't want static. My workaround was to create a class directly under the namespace and then drag it to the "foo" folder.

You can add the collapse component to the links like this..

<ul class="navbar-nav mr-auto">
     <li class="nav-item active">
         <a class="nav-link" href="#home" data-toggle="collapse" data-target=".navbar-collapse.show">Home <span class="sr-only">(current)</span></a>
     </li>
     <li class="nav-item">
         <a class="nav-link" href="#about-us" data-toggle="collapse" data-target=".navbar-collapse.show">About</a>
     </li>
     <li class="nav-item">
         <a class="nav-link" href="#pricing" data-toggle="collapse" data-target=".navbar-collapse.show">Pricing</a>
     </li>
 </ul>

$('.navbar-nav>li>a').on('click', function(){
    $('.navbar-collapse').collapse('hide');
});

Update 2021 - Bootstrap 5 (beta)

Use javascript to add a click event listener on the menu items to close the Collapse navbar..

const navLinks = document.querySelectorAll('.nav-item')
const menuToggle = document.getElementById('navbarSupportedContent')
const bsCollapse = new bootstrap.Collapse(menuToggle)
navLinks.forEach((l) => {
    l.addEventListener('click', () => { bsCollapse.toggle() })
})

BS5 demo data-attributes method

For 1D arrays, I'd recommend np.flatnonzero(array == value)[0], which is equivalent to both np.nonzero(array == value)[0][0] and np.where(array == value)[0][0] but avoids the ugliness of unboxing a 1-element tuple.

In my case, I got this error when there are 2 or more libraries conflict (same library but different versions). Check your app build.gradle in dependencies block.

Actually, you are looking for the AJAX CALL, in which you will replace the URL parameter value with the link of the JSON file to get the JSON values.

$.ajax({
    url: "File.json", //the path of the file is replaced by File.json
    dataType: "json",
    success: function (response) {
        console.log(response); //it will return the json array
    }
});

Your data is a string of '[{}]' at that point in time, you can eval it like so:

function(data) {
    data = eval( '(' + data + ')' )
}

However this method is far from secure, this will be a bit more work but the best practice is to parse it with Crockford's JSON parser: https://github.com/douglascrockford/JSON-js

Another method would be $.getJSON and you'll need to set the dataType to json for a pure jQuery reliant method.

Here is an example

import numpy as np
import matplotlib.pyplot as plt

x = np.random.rand(100)
y = np.random.rand(100)
t = np.arange(100)

plt.scatter(x, y, c=t)
plt.show()

Here you are setting the color based on the index, t, which is just an array of [1, 2, ..., 100].

Perhaps an easier-to-understand example is the slightly simpler

import numpy as np
import matplotlib.pyplot as plt

x = np.arange(100)
y = x
t = x
plt.scatter(x, y, c=t)
plt.show()

Note that the array you pass as c doesn't need to have any particular order or type, i.e. it doesn't need to be sorted or integers as in these examples. The plotting routine will scale the colormap such that the minimum/maximum values in c correspond to the bottom/top of the colormap.

Colormaps

You can change the colormap by adding

import matplotlib.cm as cm
plt.scatter(x, y, c=t, cmap=cm.cmap_name)

Importing matplotlib.cm is optional as you can call colormaps as cmap="cmap_name" just as well. There is a reference page of colormaps showing what each looks like. Also know that you can reverse a colormap by simply calling it as cmap_name_r. So either

plt.scatter(x, y, c=t, cmap=cm.cmap_name_r)
# or
plt.scatter(x, y, c=t, cmap="cmap_name_r")

will work. Examples are "jet_r" or cm.plasma_r. Here's an example with the new 1.5 colormap viridis:

import numpy as np
import matplotlib.pyplot as plt

x = np.arange(100)
y = x
t = x
fig, (ax1, ax2) = plt.subplots(1, 2)
ax1.scatter(x, y, c=t, cmap='viridis')
ax2.scatter(x, y, c=t, cmap='viridis_r')
plt.show()

Colorbars

You can add a colorbar by using

plt.scatter(x, y, c=t, cmap='viridis')
plt.colorbar()
plt.show()

Note that if you are using figures and subplots explicitly (e.g. fig, ax = plt.subplots() or ax = fig.add_subplot(111)), adding a colorbar can be a bit more involved. Good examples can be found here for a single subplot colorbar and here for 2 subplots 1 colorbar.

To view database roles assigned to users, you can use sys.database_role_members

The following query returns the members of the database roles.

SELECT DP1.name AS DatabaseRoleName,   
    isnull (DP2.name, 'No members') AS DatabaseUserName   
FROM sys.database_role_members AS DRM  
RIGHT OUTER JOIN sys.database_principals AS DP1  
    ON DRM.role_principal_id = DP1.principal_id  
LEFT OUTER JOIN sys.database_principals AS DP2  
    ON DRM.member_principal_id = DP2.principal_id  
WHERE DP1.type = 'R'
ORDER BY DP1.name;

using System.Linq;

class Program
{
    static void Main(string[] args)
    {
        int[] numbers = { 3, 9, 5 };
        int biggestNumber = numbers.Max();
        Console.WriteLine(biggestNumber);
        Console.ReadLine();
    }
}

System.Single / float - 7 digits
System.Double / double - 15-16 digits
System.Decimal / decimal - 28-29 significant digits

The way I've been stung by using the wrong type (a good few years ago) is with large amounts:

• £520,532.52 - 8 digits
• £1,323,523.12 - 9 digits

You run out at 1 million for a float.

A 15 digit monetary value:

• £1,234,567,890,123.45

9 trillion with a double. But with division and comparisons it's more complicated (I'm definitely no expert in floating point and irrational numbers - see Marc's point). Mixing decimals and doubles causes issues:

A mathematical or comparison operation that uses a floating-point number might not yield the same result if a decimal number is used because the floating-point number might not exactly approximate the decimal number.

When should I use double instead of decimal? has some similar and more in depth answers.

Using double instead of decimal for monetary applications is a micro-optimization - that's the simplest way I look at it.

This is happening because there is no package cache in the image, you need to run:

apt-get -qq update

before installing packages, and if your command is in a Dockerfile, you'll then need:

apt-get -qq -y install curl

After that install ZSH and GIT Core:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird since sh does not understand the source command. So, you do this to install zsh:

wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | zsh

and then you change your shell to zsh:

chsh -s `which zsh`

and then restart:

sudo shutdown -r 0

This problem is explained in depth in this issue.

An alternative way without the [<- function:

A sample data frame dat (shamelessly copied from @Chase's answer):

dat

  x y
1 0 2
2 1 2
3 1 1
4 2 1
5 0 0

Zeroes can be replaced with NA by the is.na<- function:

is.na(dat) <- !dat


dat

   x  y
1 NA  2
2  1  2
3  1  1
4  2  1
5 NA NA

For those who want a non-zero cellspacing value, the following CSS worked for me, but I'm only able to test it in Firefox.

See the Quirksmode link posted elsewhere for compatibility details. It seems it may not work with older Internet Explorer versions.

table {
    border-collapse: separate;
    border-spacing: 2px;
}

This is exactly what reflection is for. I don't think there's a simpler solution, but reflection isn't that code intensive anyway.

You can do this a couple of ways.

Via the "Solution Explorer"

1. Simply right-click the "References" folder and select "Manage NuGet Packages..."
2. Once that window comes up click on the option labeled "Online" in the left most part of the dialog.
3. Then in the search bar in the upper right type "json.net"
4. Click "Install" and you're done.

Via the "Package Manager Console"

1. Open the console. "View" > "Other Windows" > "Package Manager Console"
2. Then type the following:

   Install-Package Newtonsoft.Json

For more info on how to use the "Package Manager Console" check out the nuget docs.

nelek's answer is the best one posted so far, but it relies on setting the css value: white-space: pre, which might be undesirable.

I'd like to offer a different solution, which tries to tackle the real question that should've been asked here:

"How to insert untrusted text into a DOM element?"

If you trust the text, why not just use innerHTML?

domElement.innerHTML = trustedText.replace(/\r/g, '').replace(/\n/g, '<br>');

should be sufficient for all the reasonable cases.

If you decided you should use .textContent instead of .innerHTML, it means you don't trust the text that you're about to insert, right? This is a reasonable concern.

For example, you have a form where the user can create a post, and after posting it, the post text is stored in your database, and later on appended to pages whenever other users visit the relevant page.

If you use innerHTML here, you get a security breach. i.e., a user can post something like

[script]alert(1);[/script]

(try to imagine that [] are <>, apparently stack overflow is appending text in unsafe ways!)

which won't trigger an alert if you use innerHTML, but it should give you an idea why using innerHTML can have issues. a smarter user would post

[img src="invalid_src" onerror="alert(1)"]

which would trigger an alert for every other user that visits the page. Now we have a problem. An even smarter user would put display: none on that img style, and make it post the current user's cookies to a cross domain site. Congratulations, all your user login details are now exposed on the internet.

So, the important thing to understand is, using innerHTML isn't wrong, it's perfect if you're just using it to build templates using only your own trusted developer code. The real question should've been "how do I append untrusted user text that has newlines to my HTML document".

This raises a question: which strategy do we use for newlines? do we use [br] elements? [p]s or [div]s?

Here is a short function that solves the problem:

function insertUntrustedText(domElement, untrustedText, newlineStrategy) {
    domElement.innerHTML = '';
    var lines = untrustedText.replace(/\r/g, '').split('\n');
    var linesLength = lines.length;
    if(newlineStrategy === 'br') {
        for(var i = 0; i < linesLength; i++) {
            domElement.appendChild(document.createTextNode(lines[i]));
            domElement.appendChild(document.createElement('br'));
        }
    }
    else {
        for(var i = 0; i < linesLength; i++) {
            var lineElement = document.createElement(newlineStrategy);
            lineElement.textContent = lines[i];
            domElement.appendChild(lineElement);
        }
    }
}

You can basically throw this somewhere in your common_functions.js file and then just fire and forget whenever you need to append any user/api/etc -> untrusted text (i.e. not-written-by-your-own-developer-team) to your html pages.

usage example:

insertUntrustedText(document.querySelector('.myTextParent'), 'line1\nline2\r\nline3', 'br');

the parameter newlineStrategy accepts only valid dom element tags, so if you want [br] newlines, pass 'br', if you want each line in a [p] element, pass 'p', etc.

This can be done from the command line. This will create a column for your image with a NOT NULL property.

CREATE TABLE `test`.`pic` (
`idpic` INTEGER UNSIGNED NOT NULL AUTO_INCREMENT,
`caption` VARCHAR(45) NOT NULL,
`img` LONGBLOB NOT NULL,
PRIMARY KEY(`idpic`)
)
TYPE = InnoDB; 

From here

The pageContext is an implicit object available in JSPs. The EL documentation says

The context for the JSP page. Provides access to various objects including:
servletContext: ...
session: ...
request: ...
response: ...

Thus this expression will get the current HttpServletRequest object and get the context path for the current request and append /JSPAddress.jsp to it to create a link (that will work even if the context-path this resource is accessed at changes).

The primary purpose of this expression would be to keep your links 'relative' to the application context and insulate them from changes to the application path.

For example, if your JSP (named thisJSP.jsp) is accessed at http://myhost.com/myWebApp/thisJSP.jsp, thecontext path will be myWebApp. Thus, the link href generated will be /myWebApp/JSPAddress.jsp.

If someday, you decide to deploy the JSP on another server with the context-path of corpWebApp, the href generated for the link will automatically change to /corpWebApp/JSPAddress.jsp without any work on your part.

The easiest way to open an admin Powershell window in Windows 10 (and Windows 8) is to add a "Windows Powershell (Admin)" option to the "Power User Menu". Once this is done, you can open an admin powershell window via Win+X,A or by right-clicking on the start button and selecting "Windows Powershell (Admin)":

[

Here's where you replace the "Command Prompt" option with a "Windows Powershell" option:

If the value stored in PropertyLoader.RET_SECONDARY_V_ARRAY is not "V_ARRAY", then you are using different types; even if they are declared identically (e.g. both are table of number) this will not work.

You're hitting this data type compatibility restriction:

You can assign a collection to a collection variable only if they have the same data type. Having the same element type is not enough.

You're trying to call the procedure with a parameter that is a different type to the one it's expecting, which is what the error message is telling you.

Your code is calling the function and assigning the return value to onClick, also it should be 'onclick'. This is how it should look.

document.getElementById("a").onclick = Bar;

Looking at your other code you probably want to do something like this:

document.getElementById(id+"Button").onclick = function() { HideError(id); }

That query is failing and returning false.

Put this after mysqli_query() to see what's going on.

if (!$check1_res) {
    printf("Error: %s\n", mysqli_error($con));
    exit();
}

The problem here, as explained in other comments, is that the pointer is being dereference without being properly initialized. Operating systems like Linux keep the lowest addresses (eg first 32MB: 0x00_0000 -0x200_0000) out of the virtual address space of a process. This is done because dereferencing zeroed non-initialized pointers is a common mistake, like in this case. So when this type of mistake happens, instead of actually reading a random variable that happens to be at address 0x0 (but not the memory address the pointer would be intended for if initialized properly), the pointer would be reading from a memory address outside of the process's virtual address space. This causes a page fault, which results in a segmentation fault, and a signal is sent to the process to kill it. That's why you are getting the access violation error.

In this case a relatively simple GROUP BY can work, but in general, when there are additional columns where you can't order by but you want them from the particular row which they are associated with, you can either join back to the detail using all the parts of the key or use OVER():

Runnable example (Wofkflow20 error in original data corrected)

;WITH partitioned AS (
    SELECT company
        ,workflow
        ,date
        ,other_columns
        ,ROW_NUMBER() OVER(PARTITION BY company, workflow
                            ORDER BY date) AS seq
    FROM workflowTable
)
SELECT *
FROM partitioned WHERE seq = 1

using (SqlConnection sqlConnection1 = new SqlConnection("Your Connection String")) {
using (SqlCommand cmd = new SqlCommand()) {
  Int32 rowsAffected;

  cmd.CommandText = "StoredProcedureName";
  cmd.CommandType = CommandType.StoredProcedure;
  cmd.Connection = sqlConnection1;

  sqlConnection1.Open();

  rowsAffected = cmd.ExecuteNonQuery();

}}

Give a class to your cell containing the icon

<td class="icon"><i class="icon-ok"></i></td>

and then

.icon{
    text-align: center;
}

Use Powershell! Built in cmdlets for managing processes. Examples here (hard way), here(built in) and here (more).

This is another C example of where the same syntax has different meanings (in different places). While one might be able to argue that the syntax should be different for these two cases, it is what it is. The idea is that not that it is "not allowed" but that the second thing means something different (it means "pointer assignment").

Basically my code sends data to the next page like so:

**Referring Page**
$this = $_SERVER['PHP_SELF'];
echo "<a href='next_page.php?prev=$this'>Next Page</a>";

**Page with button**
$prev = $_GET['prev'];
echo "<a href='$prev'><button id='back'>Back</button></a>";

Also, your compare function is incorrect. It needs to return -1, 0, or 1, not a boolean as you have it. The correct compare function would be:

def compare(item1, item2):
    if fitness(item1) < fitness(item2):
        return -1
    elif fitness(item1) > fitness(item2):
        return 1
    else:
        return 0

# Calling
list.sort(key=compare)

Havengard's answer doesn't seem to be strictly true. I've found that vw fills the viewport width, but doesn't account for the scrollbars. So, if your content is taller than the viewport (so that your site has a vertical scrollbar), then using vw results in a small horizontal scrollbar. I had to switch out width: 100vw for width: 100% to get rid of the horizontal scrollbar.

Code for one liner isFlashExists variable:

<script type='text/javascript'
    src='//ajax.googleapis.com/ajax/libs/swfobject/2.2/swfobject.js'> </script>

<script type='text/javascript'>
   var isFlashExists = swfobject.hasFlashPlayerVersion('1') ? true : false ;
   if (isFlashExists) {
    alert ('flash exists');
   } else {
    alert ('NO flash');
   }
</script>

Note that there is an alternative like this: swfobject.getFlashPlayerVersion();

I would like to comment on this, even tough Its old post. So, basically, I want to combine 2 answers, one from this post and one from another post that I read, don't know the author of it so please sorry for using your methods.

So, here are my classes for achieveving desired result:

    public class StartActivity extends Activity {
    public static final int REQUEST_CODE = 5912;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        PackageManager p = getPackageManager();
        ComponentName componentName = new ComponentName(this, StartActivity.class); // activity which is first time open in manifiest file which is declare as <category android:name="android.intent.category.LAUNCHER" />
        p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
        startService(new Intent(this, StartService.class));
        startService(new Intent(this, SmsOutgoingService.class));
        try {
            // Initiate DevicePolicyManager.

            ComponentName mAdminName = new ComponentName(this, DeviceAdminReciever.class);

            if (!mDPM.isAdminActive(mAdminName)) {
                Intent intent = new Intent(DevicePolicyManager.ACTION_ADD_DEVICE_ADMIN);
                intent.putExtra(DevicePolicyManager.EXTRA_DEVICE_ADMIN, mAdminName);
                intent.putExtra(DevicePolicyManager.EXTRA_ADD_EXPLANATION, "Click on Activate button to secure your application.");
                startActivityForResult(intent, REQUEST_CODE);
            } else {
                mDPM.lockNow();
                finish();

        } catch (Exception e) {

    }

    @Override

inside TService class you will find CallReceiever class that is going to handle everything you need from the call. You can add parameters as per your will, but, the main point is important.

From your MainActvitiy call Service that will start your Receiever. If you want to record media from receiever directly, you will get errors, so, you need to register Receiever from service. After that, you can call start recording and end recording wherever you like. Calling return super.onStartCommand(intent, flags, startId); will have that Service lasting for more than one call, so keep that in mind.

So, this is it, its working perfectly with my Samsung Galaxy s6 Edge+, Ive tested it on Galaxy Note 4 and on Samsung J5, a big thank you to the authors of this post and the post about receieving phone calls.

It has a -force parameter.????

The simplest way to get a Python script online is to use CGI:

#!/usr/bin/python

print "Content-type: text/html"
print

print "<p>Hello world.</p>"

Put that code in a script that lives in your web server CGI directory, make it executable, and run it. The cgi module has a number of useful utilities when you need to accept parameters from the user.

If your redis is a cluster,you can use this script

#!/usr/bin/env bash
redis_list=("172.23.3.19:7001,172.23.3.19:7002,172.23.3.19:7003,172.23.3.19:7004,172.23.3.19:7005,172.23.3.19:7006")

arr=($(echo "$redis_list" | tr ',' '\n'))

for info in ${arr[@]}; do
  echo "start :${info}"
  redis_info=($(echo "$info" | tr ':' '\n'))
  ip=${redis_info[0]}
  port=${redis_info[1]}
  echo "ip="${ip}",port="${port}
  redis-cli -c -h $ip -p $port set laker$port '?????'
  redis-cli -c -h $ip -p $port keys \*

done

echo "end"

use StringBuilder and iterate over your String[], and append each String into it:

public static String convert(String[] name) { 
    StringBuilder sb = new StringBuilder();
    for (String st : name) { 
        sb.append('\'').append(st).append('\'').append(',');
    }
    if (name.length != 0) sb.deleteCharAt(sb.length()-1);
    return sb.toString();
}

This function returns a array of int in the string form like "6097321041141011026"

private String IntArrayToString(byte[] array) {
        String strRet="";
        for(int i : array) {
            strRet+=Integer.toString(i);
        }
        return strRet;
    }

I often want different columns to have different formats. Here is how I print a simple 2D array using some variety in the formatting by converting (slices of) my NumPy array to a tuple:

import numpy as np
dat = np.random.random((10,11))*100  # Array of random values between 0 and 100
print(dat)                           # Lines get truncated and are hard to read
for i in range(10):
    print((4*"%6.2f"+7*"%9.4f") % tuple(dat[i,:]))

<body onLoad="self.focus();document.formname.name.focus()" >

formname is <form action="xxx.php" method="POST" name="formname" >
and name is <input type="text" tabindex="1" name="name" />

it works for me, checked using IE and mozilla.
autofocus, somehow didn't work for me.

If all your rows have equal height, you should definitely take a look at the virtualizing ng-repeat: http://kamilkp.github.io/angular-vs-repeat/

This demo looks very promising (and it supports inertial scrolling)

This works on a Mac as noted by Alex Moore-Niemi:

set backupdir=$TMPDIR//
set directory=$TMPDIR//

Make sure to use TMPDIR and not TEMPDIR.

In your component i.e angular JS code:

function getData(){
    window.location.href = 'http://localhost:1036/api/Employee/GetExcelData';
}

have a look at the php documentation for theese functions you can send post reqeust using them.

fsockopen()
fputs()

or simply use a class like Zend_Http_Client which is also based on socket-conenctions.

also found a neat example using google...

Quick and Dirty to delete exact duplicated rows (for small tables):

select  distinct * into t2 from t1;
delete from t1;
insert into t1 select *  from t2;
drop table t2;

Make your life easier by using CSS Selectors

I know I have come late to party but I have a nice suggestion for you.

Using BeautifulSoup is already been suggested I would rather prefer using CSS Selectors to scrape data inside HTML

import urllib2
from bs4 import BeautifulSoup

main_url = "http://www.example.com"

main_page_html  = tryAgain(main_url)
main_page_soup = BeautifulSoup(main_page_html)

# Scrape all TDs from TRs inside Table
for tr in main_page_soup.select("table.class_of_table"):
   for td in tr.select("td#id"):
       print(td.text)
       # For acnhors inside TD
       print(td.select("a")[0].text)
       # Value of Href attribute
       print(td.select("a")[0]["href"])

# This is method that scrape URL and if it doesnt get scraped, waits for 20 seconds and then tries again. (I use it because my internet connection sometimes get disconnects)
def tryAgain(passed_url):
    try:
        page  = requests.get(passed_url,headers = random.choice(header), timeout = timeout_time).text
        return page
    except Exception:
        while 1:
            print("Trying again the URL:")
            print(passed_url)
            try:
                page  = requests.get(passed_url,headers = random.choice(header), timeout = timeout_time).text
                print("-------------------------------------")
                print("---- URL was successfully scraped ---")
                print("-------------------------------------")
                return page
            except Exception:
                time.sleep(20)
                continue 

Sheet.getPhysicalNumberOfRows() does not involve some empty rows. If you want to loop for all rows, do not use this to know the loop size.

$arr = array('key1'=>'value1','key2'=>'value2','key3'=>'value3');
list($last_key) = each(array_reverse($arr));
print $last_key;
// key3

public static void showCustomAlertDialog(Context context, String name,

model.predict() expects the first parameter to be a numpy array. You supply a list, which does not have the shape attribute a numpy array has.

Otherwise your code looks fine, except that you are doing nothing with the prediction. Make sure you store it in a variable, for example like this:

prediction = model.predict(np.array(tk.texts_to_sequences(text)))
print(prediction)

Documentation: C.2.3.1 <jee:jndi-lookup/> (simple)

Example:

<jee:jndi-lookup id="dataSource" jndi-name="jdbc/MyDataSource"/>

You just need to find out what JNDI name your appserver has bound the datasource to. This is entirely server-specific, consult the docs on your server to find out how.

Remember to declare the jee namespace at the top of your beans file, as described in C.2.3 The jee schema.

require_once 'lib/Zend/Loader/StandardAutoloader.php';
$loader = new Zend\Loader\StandardAutoloader(array('autoregister_zf' => true));

$loader->registerNamespace('Http\PhpEnvironment', 'lib/Zend/Http'); 

// Register with spl_autoload:
$loader->register();

$a = new Zend\Http\PhpEnvironment\Request();
print_r($a->getQuery()->get()); exit;

Easiest solution is to create the column using the correct data type: DATE

For example:

1. Create table:

   create table test_date (mydate date);

2. Insert row:

   insert into test_date values (to_date('01-01-2011','dd-mm-yyyy'));

To get the month and year, do as follows:

select to_char(mydate, 'MM-YYYY') from test_date;

Your result will be as follows: 01-2011

Another cool function to use is "EXTRACT"

select extract(year from mydate) from test_date;

This will return: 2011

Swift 2 Update There are new failable initializers that allow you to do this in more idiomatic and safe way (as many answers have noted, NSString's double value is not very safe because it returns 0 for non number values. This means that the doubleValue of "foo" and "0" are the same.)

let myDouble = Double(myString)

This returns an optional, so in cases like passing in "foo" where doubleValue would have returned 0, the failable intializer will return nil. You can use a guard, if-let, or map to handle the Optional<Double>

Original Post: You don't need to use the NSString constructor like the accepted answer proposes. You can simply bridge it like this:

(swiftString as NSString).doubleValue

I've found this script example useful (from http://www.mrexcel.com/forum/excel-questions/898899-json-api-excel.html#post4332075 ):

Sub getData()

    Dim Movie As Object
    Dim scriptControl As Object

    Set scriptControl = CreateObject("MSScriptControl.ScriptControl")
    scriptControl.Language = "JScript"

    With CreateObject("MSXML2.XMLHTTP")
        .Open "GET", "http://www.omdbapi.com/?t=frozen&y=&plot=short&r=json", False
        .send
        Set Movie = scriptControl.Eval("(" + .responsetext + ")")
        .abort
        With Sheets(2)
            .Cells(1, 1).Value = Movie.Title
            .Cells(1, 2).Value = Movie.Year
            .Cells(1, 3).Value = Movie.Rated
            .Cells(1, 4).Value = Movie.Released
            .Cells(1, 5).Value = Movie.Runtime
            .Cells(1, 6).Value = Movie.Director
            .Cells(1, 7).Value = Movie.Writer
            .Cells(1, 8).Value = Movie.Actors
            .Cells(1, 9).Value = Movie.Plot
            .Cells(1, 10).Value = Movie.Language
            .Cells(1, 11).Value = Movie.Country
            .Cells(1, 12).Value = Movie.imdbRating
        End With
    End With

End Sub

It's just to clear the adapter, add all itens and notify change like below:

  public void show(List<Object> objLIst) {
    adapter.clear();
    adapter.addAll(objLIst);
    adapter.notifyDataSetChanged(); }

One solution is to use JavaScript to add the required CSS classes after the page is ready. For example, styling django form output with bootstrap classes (jQuery used for brevity):

<script type="text/javascript">
    $(document).ready(function() {
        $('#some_django_form_id').find("input[type='text'], select, textarea").each(function(index, element) {
            $(element).addClass("form-control");
        });
    });
</script>

This avoids the ugliness of mixing styling specifics with your business logic.

Eaven if you are going to prevent sql injection front-end, using html or js checks, you'd have to consider that front-end checks are "bypassable".

You can disable js or edit a pattern with a front-end development tool (built in with firefox or chrome nowadays).

So, in order to prevent SQL injection, would be right to sanitize input date backend inside your controller.

I would like to suggest to you to use filter_input() native PHP function in order to sanitize GET and INPUT values.

If you want to go ahead with security, for sensible database queries, I'd like to suggest to you to use regular expression to validate data format. preg_match() will help you in this case! But take care! Regex engine is not so light. Use it only if necessary, otherwise your application performances will decrease.

Security has a costs, but do not waste your performance!

Easy example:

if you want to double check if a value, received from GET is a number, less then 99 if(!preg_match('/[0-9]{1,2}/')){...} is heavyer of

if (isset($value) && intval($value)) <99) {...}

So, the final answer is: "No! PDO Prepared Statements does not prevent all kind of sql injection"; It does not prevent unexpected values, just unexpected concatenation

If the frames are going to be the same size, why not create the frame and pass the frame then as a reference to it instead.

When you have passed the frame you can then decide how to populate it. It would be like having a method for calculating the average of a set of figures. Would you create the method over and over again?

I have the same problem after update visual studio, so this is how do I solve the problem.

1. Close visual studio.
2. Delete all .vs folder from my project.
3. Open visual studio.
4. Open my project.

Hope this helpful for anyone who has this problem.

This worked for me:

tar -zcvf target.tar.gz target/ --exclude="target/backups" --exclude="target/cache"

I'm running python 3.5 and subprocess.call(['./test.sh']) doesn't work for me.

I give you three solutions depends on what you wanna do with the output.

1 - call script. You will see output in your terminal. output is a number.

import subprocess 
output = subprocess.call(['test.sh'])

2 - call and dump execution and error into string. You don't see execution in your terminal unless you print(stdout). Shell=True as argument in Popen doesn't work for me.

import subprocess
from subprocess import Popen, PIPE

session = subprocess.Popen(['test.sh'], stdout=PIPE, stderr=PIPE)
stdout, stderr = session.communicate()

if stderr:
    raise Exception("Error "+str(stderr))

3 - call script and dump the echo commands of temp.txt in temp_file

import subprocess
temp_file = open("temp.txt",'w')
subprocess.call([executable], stdout=temp_file)
with open("temp.txt",'r') as file:
    output = file.read()
print(output)

Don't forget to take a look at the doc subprocess

Provide the :name option to add_index, e.g.:

add_index :studies,
  ["user_id", "university_id", "subject_name_id", "subject_type_id"], 
  unique: true,
  name: 'my_index'

If using the :index option on references in a create_table block, it takes the same options hash as add_index as its value:

t.references :long_name, index: { name: :my_index }

There are several approaches.

One is to use a non-capturing group in the regex: (?:/(?P<title>[a-zA-Z]+)/)?
Making a Regex Django URL Token Optional

Another, easier to follow way is to have multiple rules that matches your needs, all pointing to the same view.

urlpatterns = patterns('',
    url(r'^project_config/$', views.foo),
    url(r'^project_config/(?P<product>\w+)/$', views.foo),
    url(r'^project_config/(?P<product>\w+)/(?P<project_id>\w+)/$', views.foo),
)

Keep in mind that in your view you'll also need to set a default for the optional URL parameter, or you'll get an error:

def foo(request, optional_parameter=''):
    # Your code goes here

It is important to remember that React expects STABLE keys, meaning you should assign the keys once and every item on your list should receive the same key every time, that way React can optimize around your data changes when it is reconciling the virtual DOM and decides which components need to re-render. So, if you are using UUID you need to do it at the data level, not at the UI level.

Also keep in mind you can use any string you want for the key, so you can often combine several fields into one unique ID, something like ${username}_${timestamp} can be a fine unique key for a line in a chat, for example.

Issue the following command,the way to run specified logrotate:

logrotate -vf /etc/logrotate.d/custom

Options:

-v :show the process

-f :forcing run

custom :user-defined log setting

eg: mongodb-log

# mongodb-log rotate

/data/var/log/mongodb/mongod.log {
    daily
    dateext
    rotate 30
    copytruncate
    missingok
}

suppose you're posting a html form with this:

<input type="text" name="username">

If using raw cgi:

import cgi
form = cgi.FieldStorage()
print form["username"]

If using Django, Pylons, Flask or Pyramid:

print request.GET['username'] # for GET form method
print request.POST['username'] # for POST form method

Using Turbogears, Cherrypy:

from cherrypy import request
print request.params['username']

Web.py:

form = web.input()
print form.username

Werkzeug:

print request.form['username']

If using Cherrypy or Turbogears, you can also define your handler function taking a parameter directly:

def index(self, username):
    print username

Google App Engine:

class SomeHandler(webapp2.RequestHandler):
    def post(self):
        name = self.request.get('username') # this will get the value from the field named username
        self.response.write(name) # this will write on the document

So you really will have to choose one of those frameworks.

&& and || are short circuit operators operating on scalars. & and | operate on arrays, and use short-circuiting only in the context of if or while loop expressions.

Give your image an id. Then you can do this in your javascript.

document.getElementById("blaah").src="blaah";

You can use the ".___" method to change the value of any attribute of any element.

Here's an example...

static class Program
{
    [DllImport("user32.dll")]
    public static extern int SetForegroundWindow(IntPtr hWnd);

    [STAThread]
    static void Main()
    {
        while(true)
        {
            Process [] processes = Process.GetProcessesByName("iexplore");

            foreach(Process proc in processes)
            {
                SetForegroundWindow(proc.MainWindowHandle);
                SendKeys.SendWait("{F5}");
            }

            Thread.Sleep(5000);
        }
    }
}

a better one... less anoying...

{
    const UInt32 WM_KEYDOWN = 0x0100;
    const int VK_F5 = 0x74;

        while(true)
        {
            Process [] processes = Process.GetProcessesByName("iexplore");

            foreach(Process proc in processes)
                PostMessage(proc.MainWindowHandle, WM_KEYDOWN, VK_F5, 0);

            Thread.Sleep(5000);

Using code to parse ps aux for linux and tasklist for windows are your best options, until something more general comes along.

For windows, you can reference: http://www.rgagnon.com/javadetails/java-0593.html

Linux can pipe the results of ps aux through grep too, which would make processing/searching quick and easy. I'm sure you can find something similar for windows too.

I solved a similar issue by just deleting the .git folder from my project and reintegrating with version control through IntelliJ. Note: The .git folder is hidden. You can view it in the terminal with ls -a , and then remove it using rm -rf .git .

Use first the method OpenTextFile, and then...

either read the file at once with the method ReadAll:

Set file = fso.OpenTextFile("C:\test.txt", 1)
content = file.ReadAll

Learn about isset which is a built in "function" that can be used in if statements to tell if a variable has been used or set

Example:

    if(isset($_POST["testvariabel"]))
     {
       echo "testvariabel has been set!";
     }

My case was that I had generated code for three custom content types and then just pasted all the code in functions.php without renaming the "function custom_post_type" part of each function. After renaming like e.g "function employees", it worked like a charm....it displayed.

With SQL 2012 and later, you could use TRY_CAST/TRY_CONVERT to try converting to a numeric type, e.g. TRY_CAST(answer AS float) IS NOT NULL -- note though that this will match scientific notation too (1+E34). (If you use decimal, then scientific notation won't match)

You can try opening the wsdl in web browser and saving with .wsdl extension. And set the WSDL in SOAP UI project to this .wsdl file. This really works.

How about either of:

>>> df
         date  duration user_id
0  2013-04-01        30    0001
1  2013-04-01        15    0001
2  2013-04-01        20    0002
3  2013-04-02        15    0002
4  2013-04-02        30    0002
>>> df.groupby("date").agg({"duration": np.sum, "user_id": pd.Series.nunique})
            duration  user_id
date                         
2013-04-01        65        2
2013-04-02        45        1
>>> df.groupby("date").agg({"duration": np.sum, "user_id": lambda x: x.nunique()})
            duration  user_id
date                         
2013-04-01        65        2
2013-04-02        45        1

You could try:

<html>
    <head>
        <style>
            #main {
                width: 500; /*Set to whatever*/
                height: 500;/*Set to whatever*/
            }
        </style>
    </head>
    <body id="main">
    </body>
</html>

According to: https://docs.npmjs.com/files/folders

• Local install (default): puts stuff in ./node_modules of the current package root.
• Global install (with -g): puts stuff in /usr/local or wherever node is installed.
• Install it locally if you're going to require() it.
• Install it globally if you're going to run it on the command line. -> If you need both, then install it in both places, or use npm link.

prefix Configuration

The prefix config defaults to the location where node is installed. On most systems, this is /usr/local. On windows, this is the exact location of the node.exe binary.

The docs might be a little outdated, but they explain why global installs can end up in different directories:

(dev) go|c:\srv> npm config ls -l | grep prefix
; prefix = "C:\\Program Files\\nodejs" (overridden)
prefix = "C:\\Users\\bjorn\\AppData\\Roaming\\npm"

Based on the other answers, it may seem like the override is now the default location on Windows, and that I may have installed my office version prior to this override being implemented.

This also suggests a solution for getting all team members to have globals stored in the same absolute path relative to their PC, i.e. (run as Administrator):

mkdir %PROGRAMDATA%\npm
setx PATH "%PROGRAMDATA%\npm;%PATH%" /M
npm config set prefix %PROGRAMDATA%\npm

open a new cmd.exe window and reinstall all global packages.

Explanation (by lineno.):

1. Create a folder in a sensible location to hold the globals (Microsoft is adamant that you shouldn't write to ProgramFiles, so %PROGRAMDATA% seems like the next logical place.
2. The directory needs to be on the path, so use setx .. /M to set the system path (under HKEY_LOCAL_MACHINE). This is what requires you to run this in a shell with administrator permissions.
3. Tell npm to use this new path. (Note: folder isn't visible in %PATH% in this shell, so you must open a new window).

You could get the keys of the array before the foreach, then use a counter to check the next element, something like:

//$arr is the array you wish to cycle through
$keys = array_keys($arr);
$num_keys = count($keys);
$i = 1;
foreach ($arr as $a)
{
    if ($i < $num_keys && $arr[$keys[$i]] == $a)
    {
        // we have a match
    }
    $i++;
}

This will work for both simple arrays, such as array(1,2,3), and keyed arrays such as array('first'=>1, 'second'=>2, 'thrid'=>3).

You can use console.log() in Firebug or Chrome to get a good object view here, like this:

$.getJSON('my.json', function(data) {
  console.log(data);
});

If you just want to view the string, look at the Resource view in Chrome or the Net view in Firebug to see the actual string response from the server (no need to convert it...you received it this way).

If you want to take that string and break it down for easy viewing, there's an excellent tool here: http://json.parser.online.fr/

I had the same problem on OSX 10.6.6. But just a simple easy_install mysql-python on terminal did not solve it as another hiccup followed:

error: command 'gcc-4.2' failed with exit status 1.

Apparently, this issue arises after upgrading from XCode3 (which is natively shipped with OSX 10.6) to XCode4. This newer ver removes support for building ppc arch. If its the same case, try doing as follows before easy_install mysql-python

sudo bash
export ARCHFLAGS='-arch i386 -arch x86_64'
rm -r build
python setup.py build
python setup.py install

Many thanks to Ned Deily for this solution. Check here

Try in yourbatch

set "batchisin=%~dp0"

which should set the variable to your batch's location.

Actually, I did something like this:

    select case myconfigtable.valpar
       when 'WEEK' then to_char(next_day(datetime-7,'Monday'),'DD/MM/YYYY')|| ' - '|| to_char(next_day(datetime,'Sunday'),'DD/MM/YYYY')
       when 'MONTH' then to_char(to_date(yearweek,'yyyyMM'),'DD/MM/YYYY')  || ' - '|| to_char(last_day(to_date(yearweek,'yyyyMM')),'DD/MM/YYYY')
       else 'NA'
       end
from
(
select to_date(YEAR||'01','YYYYMM') + 7 * (WEEK - 1) datetime, yearweek
       from
       (
       select substr(yearweek,1,4) YEAR,
              to_number(substr(yearweek,5)) WEEK,
              yearweek
       from (select '201018' yearweek from dual
            )
       )
), myconfigtable myconfigtable
 where myconfigtable.codpar='TYPEOFPERIOD'

In short:

• getPath() gets the path string that the File object was constructed with, and it may be relative current directory.
• getAbsolutePath() gets the path string after resolving it against the current directory if it's relative, resulting in a fully qualified path.
• getCanonicalPath() gets the path string after resolving any relative path against current directory, and removes any relative pathing (. and ..), and any file system links to return a path which the file system considers the canonical means to reference the file system object to which it points.

Also, each of these has a File equivalent which returns the corresponding File object.

Note that IMO, Java got the implementation of an "absolute" path wrong; it really should remove any relative path elements in an absolute path. The canonical form would then remove any FS links or junctions in the path.

<LinearLayout

Try This Code

Visibility works fine in this code

You can implement like a below logic. Suppose you want an array of values.

let test = [ {name:'test',lastname:'kumar',age:30},
             {name:'test',lastname:'kumar',age:30},
             {name:'test3',lastname:'kumar',age:47},
             {name:'test',lastname:'kumar',age:28},
             {name:'test4',lastname:'kumar',age:30},
             {name:'test',lastname:'kumar',age:29}]

let result1 = test.map(element => 
              { 
                 if (element.age === 30) 
                 {
                    return element.lastname;
                 }
              }).filter(notUndefined => notUndefined !== undefined);

output : ['kumar','kumar','kumar']

Try the below code this will help you`

  <RelativeLayout

When you have multiple files, an idea is to show only the first file and the number of the hidden file names.

$('.custom-file input').change(function() {
    var $el = $(this),
    files = $el[0].files,
    label = files[0].name;
    if (files.length > 1) {
        label = label + " and " + String(files.length - 1) + " more files"
    }
    $el.next('.custom-file-label').html(label);
});

Here is a complete method that only has one button, an 'ok', to close the UIAlert:

- (void) myAlert: (NSString*)errorMessage
{
    UIAlertView *myAlert = [[UIAlertView alloc]
                          initWithTitle:errorMessage
                          message:@""
                          delegate:self
                          cancelButtonTitle:nil
                          otherButtonTitles:@"ok", nil];
    myAlert.cancelButtonIndex = -1;
    [myAlert setTag:1000];
    [myAlert show];
}

You can use Kotlin, the Super (cede of) Java for JVM, it has a nice way of interpolating strings like those of ES5, Ruby and Python.

class Client(val firstName: String, val lastName: String) {
    val fullName = "$firstName $lastName"
}

Improving upon @Ianl's answer,

It seems that if 2-step authentication is enabled, you have to use token instead of password. You could generate a token here.

If you want to disable the prompts for both the username and password then you can set the URL as follows -

git remote set-url origin https://username:[email protected]/WEMP/project-slideshow.git

Note that the URL has both the username and password. Also the .git/config file should show your current settings.

Update 20200128:

If you don't want to store the password in the config file, then you can generate your personal token and replace the password with the token. Here are some details.

It would look like this -

git remote set-url origin https://username:[email protected]/WEMP/project-slideshow.git

You can use this:

var token = "SOME_TOKEN";

$.ajaxPrefilter(function (options, originalOptions, jqXHR) {
  jqXHR.setRequestHeader('X-CSRF-Token', token);
});

From documentation:

jQuery.ajaxPrefilter( [dataTypes ], handler(options, originalOptions, jqXHR) )

Description: Handle custom Ajax options or modify existing options before each request is sent and before they are processed by $.ajax().

Alternatively, you can use evals from my pander package to capture output and all warnings, errors and other messages along with the raw results:

> pander::evals("5+5")
[[1]]
$src
[1] "5 + 5"

$result
[1] 10

$output
[1] "[1] 10"

$type
[1] "numeric"

$msg
$msg$messages
NULL

$msg$warnings
NULL

$msg$errors
NULL


$stdout
NULL

attr(,"class")
[1] "evals"

The answer are as below for Window authentication

$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "Server=$SQLServer;Database=$SQLDBName;Integrated Security=True;"

For bash, Bourne shell and fish:

curl -s http://server/path/script.sh | bash -s arg1 arg2

Flag "-s" makes shell read from stdin.

In one script

#! /bin/sh

# Save git data 
cp -r .git gitold
# Remove all empty git object files 
find .git -type f -empty -delete -print
# Get current branch name
branchname=$(git branch --show-current)
# Get latest commit hash
commit=$(tail -2 .git/logs/refs/heads/jwt | awk '{ print $2 }' | tr -d '[:space:]')
# Set HEAD to this latest commit
git update-ref HEAD $commit
# Pull latest changes on the current branch (consifering remote is origin)
git pull origin $branchname

echo "If everything looks fine you remove the git backup running :\n\
      $ rm -rf gitold\n\
Otherwise restore it with:\n\
      $ rm -rf .git; mv gitold .git"      

For simplicity, If you need to default to some value if nil you can use:

@something.nil? = "No" || "Yes"

php artisan make:controller --resource Backend/API/DemoController --model=Demo

You can give it a property display block; so it will behave like a div and have its own line

CSS:

.feature_desc {
   display: block;
   ....
}

Use git clone with the --depth option set to 1 to create a shallow clone with a history truncated to the latest commit.

For example:

git clone --depth 1 https://github.com/user/repo.git

To also initialize and update any nested submodules, also pass --recurse-submodules and to clone them shallowly, also pass --shallow-submodules.

For example:

git clone --depth 1 --recurse-submodules --shallow-submodules https://github.com/user/repo.git

node-crontab allows you to edit system cron jobs from node.js. Using this library will allow you to run programs even after your main process termintates. Disclaimer: I'm the developer.

If the FileInfo class has more than one ancestor class then you should definitely call all of their __init__() functions. You should also do the same for the __del__() function, which is a destructor.

There is a builtin mixin: transparentize($color, $amount);

background-color: transparentize(#F05353, .3);

The amount should be between 0 to 1;

I also ran into this issue just now while messing with laravel.

I am using wampserver for windows and had to copy the /bin/apache/apacheversion/bin/php.ini file to /bin/php/phpversion/php.ini

This is just a workaround solution:

In normal cases, use the solutions that are shipped with git. These work great in most cases. Force to LF if you share the development on Windows and Unix based systems by setting .gitattributes.

In my case there were >10 programmers developing a project in Windows. This project was checked in with CRLF and there was no option to force to LF.

Some settings were internally written on my machine without any influence on the LF format; thus some files were globally changed to LF on each small file change.

My solution:

Windows-Machines: Let everything as it is. Care about nothing, since you are a default windows 'lone wolf' developer and you have to handle like this: "There is no other system in the wide world, is it?"

Unix-Machines

1. Add following lines to a config's [alias] section. This command lists all changed (i.e. modified/new) files:

   lc = "!f() { git status --porcelain \
                | egrep -r \"^(\?| ).\*\\(.[a-zA-Z])*\" \
                | cut -c 4- ; }; f "
   

2. Convert all those changed files into dos format:

   unix2dos $(git lc)
   

3. Optionally ...

   1. Create a git hook for this action to automate this process

   2. Use params and include it and modify the grep function to match only particular filenames, e.g.:

      ... | egrep -r "^(\?| ).*\.(txt|conf)" | ...
      

   3. Feel free to make it even more convenient by using an additional shortcut:

      c2dos = "!f() { unix2dos $(git lc) ; }; f "
      

      ... and fire the converted stuff by typing

      git c2dos
      

Use DateFormat. (Sorry, but the brevity of the question does not warrant a longer or more detailed answer.)

1. you can work with this website for generate favin.ico
2. I recommend use .ico format because the png don't work with method 1 and ico could have more detail!
3. both method work with all browser but when it's automatically work what you want type a code for it? so i think method 1 is better.

You have to change your HEAD, Not yours of course but git HEAD....

So before answering let's add some background, explaining what is this HEAD.

First of all what is HEAD?

HEAD is simply a reference to the current commit (latest) on the current branch.
There can only be a single HEAD at any given time. (excluding git worktree)

The content of HEAD is stored inside .git/HEAD and it contains the 40 bytes SHA-1 of the current commit.

detached HEAD

If you are not on the latest commit - meaning that HEAD is pointing to a prior commit in history its called detached HEAD.

On the command line, it will look like this- SHA-1 instead of the branch name since the HEAD is not pointing to the tip of the current branch

A few options on how to recover from a detached HEAD:

git checkout

git checkout <commit_id>
git checkout -b <new branch> <commit_id>
git checkout HEAD~X // x is the number of commits t go back

This will checkout new branch pointing to the desired commit.
This command will checkout to a given commit.
At this point, you can create a branch and start to work from this point on.

# Checkout a given commit. 
# Doing so will result in a `detached HEAD` which mean that the `HEAD`
# is not pointing to the latest so you will need to checkout branch
# in order to be able to update the code.
git checkout <commit-id>

# create a new branch forked to the given commit
git checkout -b <branch name>

git reflog

You can always use the reflog as well.
git reflog will display any change which updated the HEAD and checking out the desired reflog entry will set the HEAD back to this commit.

Every time the HEAD is modified there will be a new entry in the reflog

git reflog
git checkout HEAD@{...}

This will get you back to your desired commit

git reset --hard <commit_id>

"Move" your HEAD back to the desired commit.

# This will destroy any local modifications.
# Don't do it if you have uncommitted work you want to keep.
git reset --hard 0d1d7fc32

# Alternatively, if there's work to keep:
git stash
git reset --hard 0d1d7fc32
git stash pop
# This saves the modifications, then reapplies that patch after resetting.
# You could get merge conflicts if you've modified things which were
# changed since the commit you reset to.

• Note: (Since Git 2.7)
  you can also use the git rebase --no-autostash as well.

git revert <sha-1>

"Undo" the given commit or commit range.
The reset command will "undo" any changes made in the given commit.
A new commit with the undo patch will be committed while the original commit will remain in the history as well.

# add new commit with the undo of the original one.
# the <sha-1> can be any commit(s) or commit range
git revert <sha-1>

This schema illustrates which command does what.
As you can see there reset && checkout modify the HEAD.

The way you tried first is actually directly possible with numpy:

import numpy
myArray = numpy.array([10,20,30,40,50,60,70,80,90])
myInt = 10
newArray = myArray/myInt

If you do such operations with long lists and especially in any sort of scientific computing project, I would really advise using numpy.

Generics:

With Java generics, you don't actually get any of the execution efficiency that you get with .NET because when you compile a generic class in Java, the compiler takes away the type parameter and substitutes Object everywhere. For instance if you have a Foo<T> class the java compiler generates Byte Code as if it was Foo<Object>. This means casting and also boxing/unboxing will have to be done in the "background".

I've been playing with Java/C# for a while now and, in my opinion, the major difference at the language level are, as you pointed, delegates.

You may solve it by adding android:fillViewport="true" to your ScrollView.

<ScrollView
      android:layout_width="match_parent"
      android:layout_height="match_parent"

before use that property, there was only one child of my list view is visible. after using that all the rows or child of list are visible.

Note: This answer addresses part of the problem. For a complete solution (in the form of a library), look at Paul Burke's answer.

You could use the URI to obtain document id, and then query either MediaStore.Images.Media.EXTERNAL_CONTENT_URI or MediaStore.Images.Media.INTERNAL_CONTENT_URI (depending on the SD card situation).

To get document id:

// Will return "image:x*"
String wholeID = DocumentsContract.getDocumentId(uriThatYouCurrentlyHave);

// Split at colon, use second item in the array
String id = wholeID.split(":")[1];

String[] column = { MediaStore.Images.Media.DATA };     

// where id is equal to             
String sel = MediaStore.Images.Media._ID + "=?";

Cursor cursor = getContentResolver().
                          query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, 
                          column, sel, new String[]{ id }, null);

String filePath = "";

int columnIndex = cursor.getColumnIndex(column[0]);

if (cursor.moveToFirst()) {
    filePath = cursor.getString(columnIndex);
}   

cursor.close();

Reference: I'm not able to find the post that this solution is taken from. I wanted to ask the original poster to contribute here. Will look some more tonight.

border-spacing: 0; should work as well

It seems you need DataFrame.var:

Normalized by N-1 by default. This can be changed using the ddof argument

var1 = credit_card.var()

Sample:

#random dataframe
np.random.seed(100)
credit_card = pd.DataFrame(np.random.randint(10, size=(5,5)), columns=list('ABCDE'))
print (credit_card)
   A  B  C  D  E
0  8  8  3  7  7
1  0  4  2  5  2
2  2  2  1  0  8
3  4  0  9  6  2
4  4  1  5  3  4

var1 = credit_card.var()
print (var1)
A     8.8
B    10.0
C    10.0
D     7.7
E     7.8
dtype: float64

var2 = credit_card.var(axis=1)
print (var2)
0     4.3
1     3.8
2     9.8
3    12.2
4     2.3
dtype: float64

If need numpy solutions with numpy.var:

print (np.var(credit_card.values, axis=0))
[ 7.04  8.    8.    6.16  6.24]

print (np.var(credit_card.values, axis=1))
[ 3.44  3.04  7.84  9.76  1.84]

Differences are because by default ddof=1 in pandas, but you can change it to 0:

var1 = credit_card.var(ddof=0)
print (var1)
A    7.04
B    8.00
C    8.00
D    6.16
E    6.24
dtype: float64

var2 = credit_card.var(ddof=0, axis=1)
print (var2)
0    3.44
1    3.04
2    7.84
3    9.76
4    1.84
dtype: float64

I had this problem along with mismatch in ITERATOR_DEBUG_LEVEL. As a sunday-evening problem after all seemed ok and good to go, I was put out for some time. Working in de VS2017 IDE (Solution Explorer) I had recently added/copied a sourcefile reference to my project (ctrl-drag) from another project. Looking into properties->C/C++/Preprocessor - at source file level, not project level - I noticed that in a Release configuration _DEBUG was specified instead of NDEBUG for this source file. Which was all the change needed to get rid of the problem.

Below are the working steps without the need for any external modules:

Step 1: Create a module in your app.

E.g, lets assume we have an app called user_registration_app. Explore user_registration_app and create a new file.

Lets call this as custom_cors_middleware.py

Paste the below Class definition:

class CustomCorsMiddleware:
    def __init__(self, get_response):
        self.get_response = get_response
        # One-time configuration and initialization.

    def __call__(self, request):
        # Code to be executed for each request before
        # the view (and later middleware) are called.

        response = self.get_response(request)
        response["Access-Control-Allow-Origin"] = "*"
        response["Access-Control-Allow-Headers"] = "*"

        # Code to be executed for each request/response after
        # the view is called.

        return response

Step 2: Register a middleware

In your projects settings.py file, add this line

'user_registration_app.custom_cors_middleware.CustomCorsMiddleware'

E.g:

  MIDDLEWARE = [
        'user_registration_app.custom_cors_middleware.CustomCorsMiddleware', # ADD THIS LINE BEFORE CommonMiddleware
         ...
        'django.middleware.common.CommonMiddleware',

    ]

Remember to replace user_registration_app with the name of your app where you have created your custom_cors_middleware.py module.

You can now verify it will add the required response headers to all the views in the project!

Check these links: http://www.orcsweb.com/blog/james/powershell-ing-on-windows-server-how-to-import-certificates-using-powershell/

Import-Certificate: http://poshcode.org/1937

You can do something like:

dir -Path C:\Certs -Filter *.cer | Import-Certificate -CertFile $_ -StoreNames AuthRoot, Root -LocalMachine -Verbose

Not sure if this is what you're after, but it will loop through the range that you gave it and if it finds an "A" it will remove it from the cell. I'm not sure what oldStr is used for...

Private Sub foo()
Dim myString As String
RowCount = WorksheetFunction.CountA(Range("A:A"))

For i = 2 To RowCount
    myString = Trim(Cells(i, 1).Value)
    If InStr(myString, "A") > 0 Then
        Cells(i, 1).Value = Left(myString, InStr(myString, "A"))
    End If
Next
End Sub

git branch -f <branch-name> [<new-tip-commit>]

If new-tip-commit is omitted it defaults to the current commit.

All I needed was this :

SimpleDateFormat sdf = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");
sdf.setTimeZone(TimeZone.getTimeZone("GMT"));

SimpleDateFormat sdfLocal = new SimpleDateFormat("yyyy.MM.dd HH:mm:ss");

try {
    String d = sdf.format(new Date());
    System.out.println(d);
    System.out.println(sdfLocal.parse(d));
} catch (Exception e) {
    e.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
}

Output : slightly dubious, but I want only the date to be consistent

In python: help(my_list.append) for example, will give you the docstring of the function.

>>> my_list = []
>>> help(my_list.append)

    Help on built-in function append:

    append(...)
        L.append(object) -- append object to end

You need to use the overflow option, but with the following parameters:

.nav {
    max-height:300px;
    overflow-y:auto;  
}

Use overflow-y:auto; so the scrollbar only appears when the content exceeds the maximum height.

If you use overflow-y:scroll, the scrollbar will always be visible - on all .nav - regardless if the content exceeds the maximum heigh or not.

Presumably you want something that adapts itself to the content rather then the the opposite.

Hope it may helpful

Try

td.description {_x000D_
  line-height: 15px_x000D_
}

<td class="description">Description</td>

Set the line-height value to the desired value.

i also have a solution with standard inputs and outputs

#include<stdio.h>
#include<malloc.h>
int main()
{
    char *str,ch;
    int size=10,len=0;
    str=realloc(NULL,sizeof(char)*size);
    if(!str)return str;
    while(EOF!=scanf("%c",&ch) && ch!="\n")
    {
        str[len++]=ch;
        if(len==size)
        {
            str = realloc(str,sizeof(char)*(size+=10));
            if(!str)return str;
        }
    }
    str[len++]='\0';
    printf("%s\n",str);
    free(str);
}

As m.edmondson mentioned, "The remote host closed the connection." occurs when a user or browser cancels something, or the network connection drops etc. It doesn't necessarily have to be a file download however, just any request for any resource that results in a response to the client. Basically the error means that the response could not be sent because the server can no longer talk to the client(browser).

There are a number of steps that you can take in order to stop it happening. If you are manually sending something in the response with a Response.Write, Response.Flush, returning data from a web servivce/page method or something similar, then you should consider checking Response.IsClientConnected before sending the response. Also, if the response is likely to take a long time or a lot of server-side processing is required, you should check this periodically until the response.end if called. See the following for details on this property:

http://msdn.microsoft.com/en-us/library/system.web.httpresponse.isclientconnected.aspx

Alternatively, which I believe is most likely in your case, the error is being caused by something inside the framework. The following link may by of use:

http://blog.whitesites.com/fixing-The-remote-host-closed-the-connection-The-error-code-is-0x80070057__633882307305519259_blog.htm

The following stack-overflow post might also be of interest:

"The remote host closed the connection" in Response.OutputStream.Write

The function below works perfectly for me:

// Note this *is* JQuery, see below for JS solution instead
function replaceText(selector, text, newText, flags) {
  var matcher = new RegExp(text, flags);
  $(selector).each(function () {
    var $this = $(this);
    if (!$this.children().length)
       $this.text($this.text().replace(matcher, newText));
  });
}

Here's a usage example:

function replaceAllText() {
  replaceText('*', 'hello', 'hi', 'g');
}

$(document).ready(replaceAllText);
$('html').ajaxStop(replaceAllText);

You can also use do a direct replacement like so:

document.body.innerHTML = document.body.innerHTML.replace('hello', 'hi');

But be careful with it since it may affect the tags, css and scripts as well.

EDIT: As for a pure JavaScript solution use this method instead:

function replaceText(selector, text, newText, flags) {
  var matcher = new RegExp(text, flags);
  var elems = document.querySelectorAll(selector), i;

  for (i = 0; i < elems.length; i++)
    if (!elems[i].childNodes.length)
      elems[i].innerHTML = elems[i].innerHTML.replace(matcher, newText);
}

UINavigationBar *nbar = self.navigationController.navigationBar;

if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
   //iOS 7
   nbar.barTintColor = [UIColor blueColor]; // bar color
   //or custom color 
   //[UIColor colorWithRed:19.0/255.0 green:86.0/255.0 blue:138.0/255.0 alpha:1];

   nbar.navigationBar.translucent = NO;

   nbar.tintColor = [UIColor blueColor]; //bar button item color

} else {
   //ios 4,5,6
   nbar.tintColor = [UIColor whiteColor];
   //or custom color
   //[UIColor colorWithRed:19.0/255.0 green:86.0/255.0 blue:138.0/255.0 alpha:1];

}

You have to create an instance of that class within the static method and then call it.

For example like this:

public class MyClass
{
   private void data1()
   {
   }
   private static void data2()
   {
     MyClass c = new MyClass();
     c.data1();
   }
}

DECLARE   @UserOptions TABLE(SetOption varchar(100), Value varchar(100))
DECLARE   @IsolationLevel varchar(100)

INSERT    @UserOptions
EXEC('DBCC USEROPTIONS WITH NO_INFOMSGS')

SELECT    @IsolationLevel = Value
FROM      @UserOptions
WHERE     SetOption = 'isolation level'

-- Do whatever you want with the variable here...  
PRINT     @IsolationLevel

I think you will want to use ThreadSafeClientConnManager.

You can see how it works here: http://foo.jasonhudgins.com/2009/08/http-connection-reuse-in-android.html

Or in the AndroidHttpClient which uses it internally.

I'm glad that worked out, so I guess you had to explicitly set 'auto' on IE6 in order for it to mimic other browsers!

I actually recently found another technique for scaling images, again designed for backgrounds. This technique has some interesting features:

1. The image aspect ratio is preserved
2. The image's original size is maintained (that is, it can never shrink only grow)

The markup relies on a wrapper element:

<div id="wrap"><img src="test.png" /></div>

Given the above markup you then use these rules:

#wrap {
  height: 100px;
  width: 100px;
}
#wrap img {
  min-height: 100%;
  min-width: 100%;
}

If you then control the size of wrapper you get the interesting scale effects that I list above.

To be explicit, consider the following base state: A container that is 100x100 and an image that is 10x10. The result is a scaled image of 100x100.

1. Starting at the base state, the container resized to 20x100, the image stays resized at 100x100.
2. Starting at the base state, the image is changed to 10x20, the image resizes to 100x200.

So, in other words, the image is always at least as big as the container, but will scale beyond it to maintain it's aspect ratio.

This probably isn't useful for your site, and it doesn't work in IE6. But, it is useful to get a scaled background for your view port or container.

1. Create a hidden button with id="hiddenBtn" and type="submit" that do the submit
2. Change current button to type="button"

3. set onclick of the current button call a function look like below:

   function foo() { // do something before submit ... // trigger click event of the hidden button $('#hinddenBtn').trigger("click"); }

get all data from table

db.student.find({})

SELECT * FROM student

get all data from table without _id

db.student.find({}, {_id:0})

SELECT name, roll FROM student

get all data from one field with _id

db.student.find({}, {roll:1})

SELECT id, roll FROM student

get all data from one field without _id

db.student.find({}, {roll:1, _id:0})

SELECT roll FROM student

find specified data using where clause

db.student.find({roll: 80})

SELECT * FROM students WHERE roll = '80'

find a data using where clause and greater than condition

db.student.find({ "roll": { $gt: 70 }}) // $gt is greater than 

SELECT * FROM student WHERE roll > '70'

find a data using where clause and greater than or equal to condition

db.student.find({ "roll": { $gte: 70 }}) // $gte is greater than or equal

SELECT * FROM student WHERE roll >= '70'

find a data using where clause and less than or equal to condition

db.student.find({ "roll": { $lte: 70 }}) // $lte is less than or equal

SELECT * FROM student WHERE roll <= '70'

find a data using where clause and less than to condition

db.student.find({ "roll": { $lt: 70 }})  // $lt is less than

SELECT * FROM student WHERE roll < '70'

It looks like the class.phpmailer.php file is corrupt. I would download the latest version and try again.

I've always used phpMailer's SMTP feature:

$mail->IsSMTP();
$mail->Host = "localhost";

And if you need debug info:

$mail->SMTPDebug  = 2; // enables SMTP debug information (for testing)
                       // 1 = errors and messages
                       // 2 = messages only

The second argument of date is a UNIX timestamp, not a database timestamp string.

You need to convert your database timestamp with strtotime.

<?= date("c", strtotime($post[3])) ?>

since your over div doesn't have a positioning, the z-index doesn't know where and how to position it (and with respect to what?). Just change your over div's position to relative, so there is no side effects on that div and then the under div will obey to your will.

here is your example on jsfiddle: Fiddle

edit: I see someone already mentioned this answer!

A simple solution that worked for me is to close the Terminal and restart it.

Use this line given below instead of header() function.

echo "<script>window.top.location = 'https://apps.facebook.com/yourappnamespace/';</script>";

I had a similar issue.

Cause:

import HomeComponent from "components/HomeComponent";

Solution:

import HomeComponent from "./components/HomeComponent";

NOTE: ./ was before components. You can read @Zac Kwan's post above on how to use import

Also see: the official Which remote URL should I use? answer on help.github.com.

EDIT:

It seems that it's no longer necessary to have write access to a public repo to use an SSH URL, rendering my original explanation invalid.

ORIGINAL:

Apparently the main reason for favoring HTTPS URLs is that SSH URL's won't work with a public repo if you don't have write access to that repo.

The use of SSH URLs is encouraged for deployment to production servers, however - presumably the context here is services like Heroku.

As you didn't give us very much information, I'm assuming the language you're writing the code in is C#. First of all: Prefer System.Collections.Generic.List over an ArrayList. Secondly: One way would be to loop through every item in the list and check whether it contains "How". Another way would be to use LINQ. Here's a quick example that filters out every item which doesn't contain "How":

var list = new List<string>();
list.AddRange(new string[] {
    "How are you?",
    "How you doing?",
    "Joe",
    "Mike", });

foreach (string str in list.Where(s => s.Contains("How")))
{
    Console.WriteLine(str);
}
Console.ReadLine();

sh files are unix (linux) shell executables files, they are the equivalent (but much more powerful) of bat files on windows.

So you need to run it from a linux console, just typing its name the same you do with bat files on windows.

Yes you can. Since you are using spring, check out @PropertySource anotation.

Anotate your configuration with

@PropertySource("application-${spring.profiles.active}.properties")

You can call it what ever you like, and add inn multiple property files if you like too. Can be nice if you have more sets and/or defaults that belongs to all environments (can be written with @PropertySource{...,...,...} as well).

@PropertySources({
  @PropertySource("application-${spring.profiles.active}.properties"),
  @PropertySource("my-special-${spring.profiles.active}.properties"),
  @PropertySource("overridden.properties")})

Then you can start the application with environment

-Dspring.active.profiles=test

In this example, name will be replaced with application-test-properties and so on.

Clone is slow. For performance should probably start with blank hash and merge. Doesn't cover case of nested hashes...

require 'benchmark'

def bench  Benchmark.bm do |b|    
    test = {'a' => 1, 'b' => 2, 'c' => 3, 4 => 'd'}
    b.report 'clone' do
      1_000_000.times do |i|
        h = test.clone
        h['new'] = 5
      end
    end
    b.report 'merge' do
      1_000_000.times do |i|
        h = {}
        h['new'] = 5
        h.merge! test
      end
    end
    b.report 'inject' do
      1_000_000.times do |i|
        h = test.inject({}) do |n, (k, v)|
          n[k] = v;
          n
        end
        h['new'] = 5
      end
    end
  end
end

  bench  user      system      total        ( real)
  clone  1.960000   0.080000    2.040000    (  2.029604)
  merge  1.690000   0.080000    1.770000    (  1.767828)
  inject 3.120000   0.030000    3.150000    (  3.152627)
  

There are several ways to do an email from HTML. Typically you see people doing a mailto like so:

<a href="mailto:[email protected]">Click to email</a>

But if you are doing it from a button you may want to look into a javascript solution.

Create Bean for Rest Template to auto wiring the Rest Template object.

@SpringBootApplication
public class ChatAppApplication {

    @Bean
    public RestTemplate getRestTemplate(){
        return new RestTemplate();
    }

    public static void main(String[] args) {
        SpringApplication.run(ChatAppApplication.class, args);
    }

}

Consume the GET/POST API by using RestTemplate - exchange() method. Below is for the post api which is defined in the controller.

@RequestMapping(value = "/postdata",method = RequestMethod.POST)
    public String PostData(){

       return "{\n" +
               "   \"value\":\"4\",\n" +
               "   \"name\":\"David\"\n" +
               "}";
    }

    @RequestMapping(value = "/post")
    public String getPostResponse(){
        HttpHeaders headers=new HttpHeaders();
        headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
        HttpEntity<String> entity=new HttpEntity<String>(headers);
        return restTemplate.exchange("http://localhost:8080/postdata",HttpMethod.POST,entity,String.class).getBody();
    }

Thought I would add one more to the list. Texas A&M has a pretty decently priced service here: http://geoservices.tamu.edu/Services/Geocode/

A good option if you have a pretty large set of addresses to geocode and don't want to pat 10k to Google or Microsoft. We still ended up using the returned data in a Google Map.

I work on 60-70% zoom vue and my dropdown are unreadable so I made this simple code to overcome the issue

Note that I selected first all my dropdown lsts (CTRL+mouse click), went on formula tab, clicked "define name" and called them "ProduktSelection"

Private Sub Worksheet_SelectionChange(ByVal Target As Range)

Dim KeyCells As Range
Set KeyCells = Range("ProduktSelection")
    If Not Application.Intersect(KeyCells, Range(Target.Address)) _
           Is Nothing Then

ActiveWindow.Zoom = 100

End If

End Sub

I then have another sub

Private Sub Worksheet_Change(ByVal Target As Range) 

where I come back to 65% when value is changed.

Have you used the variable sum anywhere else? That would explain it.

>>> sum = 1
>>> numbers = [1, 2, 3]
>>> numsum = (sum(numbers))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'int' object is not callable

The name sum doesn't point to the function anymore now, it points to an integer.

Solution: Don't call your variable sum, call it total or something similar.

Does m really need to be a data.frame() or will a matrix() suffice?

m <- matrix(0, ncol = 30, nrow = 2)

You can wrap a data.frame() around that if you need to:

m <- data.frame(m)

or all in one line: m <- data.frame(matrix(0, ncol = 30, nrow = 2))

It may very well be a mistake on the original author, however the notion that 1 is true and 0 is false is not a universal concept. In shell scripting 0 is returned for success, and any other number for failure. In other languages such as Ruby, only nil and false are considered false, and any other value is considered true, so in Ruby both 1 and 0 would be considered true.

When you are dumping all database. Obviously it is having large data. So you can prefer below for better:

Creating Backup:

mysqldump -u [user] -p[password]--single-transaction --quick --all-databases | gzip > alldb.sql.gz

If error

-- Warning: Skipping the data of table mysql.event. Specify the --events option explicitly.

Use:

mysqldump -u [user] -p --events --single-transaction --quick --all-databases | gzip > alldb.sql.gz

Restoring Backup:

gunzip < alldb.sql.gz | mysql -u [user] -p[password]

Hope it will help :)

It follows the convention that static methods should be thread-safe, but actually in v2 that static api is a proxy to an instance method on a default instance: in the case protobuf-net, it internally minimises contention points, and synchronises the internal state when necessary. Basically the library goes out of its way to do things right so that you can have simple code.

I just installed Fedora 16 (yea, I know it's old and not supported but, I had the CD burnt :) )

Anyway, coming to the solution, this is what I was required to do:

su -
gedit /etc/phpMyAdmin/config.inc.php

if not found... try phpmyadmin - all small caps.

gedit /etc/phpmyadmin/config.inc.php

Locate

$cfg['Servers'][$i]['AllowNoPassword']

and set it to:

$cfg['Servers'][$i]['AllowNoPassword'] = TRUE;

Save it.

Inspired by JD Smith's marvellous regular expression solution, I suddenly had this head-splitting idea:

var D = Date().toString().split(" ");_x000D_
console.log(D[2] + "-" + D[1] + "-" + D[3]);

Oh okay read the question wrong, I guess it's about going backward in an array? if so, I have this:

array = ["ty", "rogers", "smith", "davis", "tony", "jack", "john", "jill", "harry", "tom", "jane", "hilary", "jackson", "andrew", "george", "rachel"]


counter = 0   

for loop in range(len(array)):
    if loop <= len(array):
        counter = -1
        reverseEngineering = loop + counter
        print(array[reverseEngineering])

<parent>
    <groupId>com.dummy.bla</groupId>
    <artifactId>parent</artifactId>
    <version>0.1-SNAPSHOT</version>     
 </parent>

 <groupId>com.dummy.bla.sub</groupId>
 <artifactId>kid</artifactId>

You mean you want to remove the version from parent block of B's pom, I think you can not do it, the groupId, artifactId, and version specified the parent's pom coordinate's, what you can omit is child's version.

CHARINDEX will return 0 if no spaces are in the string and then you look for a substring of -1 length.

You can tack a trailing space on to the end of the string to ensure there is always at least one space and avoid this problem.

SELECT SUBSTRING(PostCode, 1 , CHARINDEX(' ', PostCode + ' ' ) -1)

in c compiler

a[i]
i[a]
*(a+i)

are different ways to refer to an element in an array ! (NOT AT ALL WEIRD)

Using the sapply

 patterns <- c("A1", "A9", "A6")
         df <- data.frame(name=c("A","Ale","Al","lex","x"),Letters=c("A1","A2","A9","A1","A9"))



   name Letters
1    A      A1
2  Ale      A2
3   Al      A9
4  lex      A1
5    x      A9


 df[unlist(sapply(patterns, grep, df$Letters, USE.NAMES = F)), ]
  name Letters
1    A      A1
4  lex      A1
3   Al      A9
5    x      A9

To checkout the branch via Jenkins scripts use:

stage('Checkout SCM') {
    git branch: 'branchName', credentialsId: 'your_credentials', url: "giturlrepo"
}

In my view, most of the other answers are obsoleted by rio::import_list, which is a succinct one-liner:

library(rio)
my_data <- import_list(dir("path_to_directory", pattern = ".csv", rbind = TRUE))

Any extra arguments are passed to rio::import. rio can deal with almost any file format R can read, and it uses data.table's fread where possible, so it should be fast too.

Bootstrap 4

Now that BS4 is flexbox, the fixed-fluid is simple. Just set the width of the fixed column, and use the .col class on the fluid column.

.sidebar {
    width: 180px;
    min-height: 100vh;
}

<div class="row">
    <div class="sidebar p-2">Fixed width</div>
    <div class="col bg-dark text-white pt-2">
        Content
    </div>
</div>

Bootstrap 3..

One approach to a fixed-fluid layout is using media queries that align with Bootstrap's breakpoints so that you only use the fixed width columns are larger screens and then let the layout stack responsively on smaller screens...

@media (min-width:768px) {
  #sidebar {
      min-width: 300px;
      max-width: 300px;
  }
  #main {
      width:calc(100% - 300px);
  }
}

Problems with serializing

public class DemoList : List<Demo>
{
    // using XmlSerializer this properties won't be seralized
    // There is no error, the data is simply not there.
    string AnyPropertyInDerivedFromList { get; set; }     
}

public class Demo
{
    // this properties will be seralized
    string AnyPropetyInDemo { get; set; }  
}

Further reading: When a class is inherited from List<>, XmlSerializer doesn't serialize other attributes

You can use this method.

    public static File getRobotCacheFile(Context context) throws IOException {
        File cacheFile = new File(context.getCacheDir(), "robot.png");
        try {
            InputStream inputStream = context.getAssets().open("robot.png");
            try {
                FileOutputStream outputStream = new FileOutputStream(cacheFile);
                try {
                    byte[] buf = new byte[1024];
                    int len;
                    while ((len = inputStream.read(buf)) > 0) {
                        outputStream.write(buf, 0, len);
                    }
                } finally {
                    outputStream.close();
                }
            } finally {
                inputStream.close();
            }
        } catch (IOException e) {
            throw new IOException("Could not open robot png", e);
        }
        return cacheFile;
    }

You should never use InputStream.available() in such cases. It returns only bytes that are buffered. Method with .available() will never work with bigger files and will not work on some devices at all.

In Kotlin (;D):

@Throws(IOException::class)
fun getRobotCacheFile(context: Context): File = File(context.cacheDir, "robot.png")
    .also {
        it.outputStream().use { cache -> context.assets.open("robot.png").use { it.copyTo(cache) } }
    }

I used this approach in a recent project and I was pretty happy with the result:

.select-wrapper {
    position: relative;
    &::after {
        position: absolute;
        top: 0;
        right: 0;
        width: 100px;
        height: 100%;
        content: "";
        background: linear-gradient(to right, transparent, white);
        pointer-events: none;
    }
}

Basically, wrap the select in a div and insert a pseudo element to overlay the end of the text to create the appearance that the text fades out.

pgAdmin has GUI for data import since 1.16. You have to create your table first and then you can import data easily - just right-click on the table name and click on Import.

Try with simple c++ code in VC++.

#include <windows.h>
#include <iostream>
#pragma comment(lib, "winmm.lib")

int main(int argc, char* argv[])
{
std::cout<<"Sound playing... enjoy....!!!";
PlaySound("C:\\temp\\sound_test.wav", NULL, SND_FILENAME); //SND_FILENAME or SND_LOOP
return 0;
}

Clone-: It will create exactly duplicate copy of your remote repository project in your local machine.

Pull-: Suppose two or more than two people are sharing the same repository. (Suppose another person name is Syam) (A Repository is a place where your project exist in Github) So if Syam does some changes in the same project in his local and pushes it to the remote repository So whatever the changes Syam did those changes will not reflect in your local. So to reflect those new changes in your local you have to use git pull. Overall we use git pull to update the project.

So basically we use git clone only once whereas we use git pull many times.

Just use the == with the negation symbol (!). If dtfm is the name of your data.frame:

dtfm[!dtfm$C == "Foo", ]

Or, to move the negation in the comparison:

dtfm[dtfm$C != "Foo", ]

Or, even shorter using subset():

subset(dtfm, C!="Foo")

You could also write a reusable class for QueryParam-annotated variables

public class DateParam {
  private SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");

  private Calendar date;

  public DateParam(String in) throws WebApplicationException {
    try {
      date = Calendar.getInstance();
      date.setTime(format.parse(in));
    }
    catch (ParseException exception) {
      throw new WebApplicationException(400);
    }
  }
  public Calendar getDate() {
    return date;
  }
  public String format() {
    return format.format(value.getTime());
  }
}

then use it like this:

private @QueryParam("from") DateParam startDateParam;
private @QueryParam("to") DateParam endDateParam;
// ...
startDateParam.getDate();

Although the error handling is trivial in this case (throwing a 400 response), using this class allows you to factor-out parameter handling in general which might include logging etc.

A DataFrame is an RDD that has a schema. You can think of it as a relational database table, in that each column has a name and a known type. The power of DataFrames comes from the fact that, when you create a DataFrame from a structured dataset (Json, Parquet..), Spark is able to infer a schema by making a pass over the entire (Json, Parquet..) dataset that's being loaded. Then, when calculating the execution plan, Spark, can use the schema and do substantially better computation optimizations. Note that DataFrame was called SchemaRDD before Spark v1.3.0

Yes, you can use what's known as :nth-child selectors.

In this case you would use:

li:nth-child(3n) {
// Styling for every third element here.
}

:nth-child(3n):

3(0) = 0
3(1) = 3
3(2) = 6
3(3) = 9
3(4) = 12

:nth-child() is compatible in Chrome, Firefox, and IE9+.

For a work around to use :nth-child() amongst other pseudo-classes/attribute selectors in IE6 through to IE8, see this link.

I explain this to users by comparing Perforce changelists to a stack (from data structures).

Backing out removes one item from anywhere in the stack.

Rolling back removes n items from the top of the stack.
