Referencing Qwerty's answer, you can avoid to inflate XL size by re-using cellStyle. And when the type is CELL_TYPE_BLANK, getStringCellValue returns "" instead of null.

private static void copyRow(Sheet worksheet, int sourceRowNum, int destinationRowNum) {
  // Get the source / new row
  Row newRow = worksheet.getRow(destinationRowNum);
  Row sourceRow = worksheet.getRow(sourceRowNum);

  // If the row exist in destination, push down all rows by 1 else create a new row
  if (newRow != null) {
    worksheet.shiftRows(destinationRowNum, worksheet.getLastRowNum(), 1);
  } else {
    newRow = worksheet.createRow(destinationRowNum);
  }

  // Loop through source columns to add to new row
  for (int i = 0; i < sourceRow.getLastCellNum(); i++) {
    // Grab a copy of the old/new cell
    Cell oldCell = sourceRow.getCell(i);
    Cell newCell = newRow.createCell(i);

    // If the old cell is null jump to next cell
    if (oldCell == null) {
      newCell = null;
      continue;
    }

    // Use old cell style
    newCell.setCellStyle(oldCell.getCellStyle());

    // If there is a cell comment, copy
    if (newCell.getCellComment() != null) {
      newCell.setCellComment(oldCell.getCellComment());
    }

    // If there is a cell hyperlink, copy
    if (oldCell.getHyperlink() != null) {
      newCell.setHyperlink(oldCell.getHyperlink());
    }

    // Set the cell data type
    newCell.setCellType(oldCell.getCellType());

    // Set the cell data value
    switch (oldCell.getCellType()) {
    case Cell.CELL_TYPE_BLANK:
      break;
    case Cell.CELL_TYPE_BOOLEAN:
      newCell.setCellValue(oldCell.getBooleanCellValue());
      break;
    case Cell.CELL_TYPE_ERROR:
      newCell.setCellErrorValue(oldCell.getErrorCellValue());
      break;
    case Cell.CELL_TYPE_FORMULA:
      newCell.setCellFormula(oldCell.getCellFormula());
      break;
    case Cell.CELL_TYPE_NUMERIC:
      newCell.setCellValue(oldCell.getNumericCellValue());
      break;
    case Cell.CELL_TYPE_STRING:
      newCell.setCellValue(oldCell.getRichStringCellValue());
      break;
    }
  }
}

Since Sheet.getPhysicalNumberOfRows() does not count empty rows and Sheet.getLastRowNum() returns 0 both if there is one row or no rows, I use a combination of the two methods to accurately calculate the total number of rows.

int rowTotal = sheet.getLastRowNum();

if ((rowTotal > 0) || (sheet.getPhysicalNumberOfRows() > 0)) {
    rowTotal++;
}

Note: This will treat a spreadsheet with one empty row as having none but for most purposes this is probably okay.

Use FROM_UNIXTIME():

SELECT
  FROM_UNIXTIME(timestamp) 
FROM 
  your_table;

See also: MySQL documentation on FROM_UNIXTIME().

There is no inherent ordering to a table. So, the row number itself is a meaningless metric.

However, you can get the row number of a result set by using the ROWNUM psuedocolumn or the ROW_NUMBER() analytic function, which is more powerful.

As there is no ordering to a table both require an explicit ORDER BY clause in order to work.

select rownum, a.*
  from ( select *
           from student
          where name like '%ram%'
          order by branch
                ) a

or using the analytic query

select row_number() over ( order by branch ) as rnum, a.*
  from student
 where name like '%ram%'

Your syntax where name is like ... is incorrect, there's no need for the IS, so I've removed it.

The ORDER BY here relies on a binary sort, so if a branch starts with anything other than B the results may be different, for instance b is greater than B.

As of now (studio 0.61) maintaining proper project structure is enough. No need to create separate test project as in eclipse (see below).

An actual JSON request would look like this:

data: '{"command":"on"}',

Where you're sending an actual JSON string. For a more general solution, use JSON.stringify() to serialize an object to JSON, like this:

data: JSON.stringify({ "command": "on" }),

To support older browsers that don't have the JSON object, use json2.js which will add it in.

What's currently happening is since you have processData: false, it's basically sending this: ({"command":"on"}).toString() which is [object Object]...what you see in your request.

You can use axis:

> axis(side=1, at=c(0:23))

That is, something like this:

plot(0:23, d, type='b', axes=FALSE)
axis(side=1, at=c(0:23))
axis(side=2, at=seq(0, 600, by=100))
box()

Painless, easiest and the most universal method is simply executing it with ~.bash_profile or ~.profile (if you don't have bash_profile file).

Just add the execution command at the bottom of that file and it will be executed when system started.

I have this one at the bottom an example; ~\Desktop\sound_fixer.sh

It's because size_t can be anything other than an int (maybe a struct). The idea is that it decouples it's job from the underlying type.

i am not allowed to comment due to my low reputation, but SilentGhosts solution should be much easier with file.readlines([sizehint])

python file methods

edit: SilentGhost is right, but this should be better than:

s = "" 
for i in xrange(100): 
   s += file.next()

The course contains a logical error:

    assertTrue("Book check in failed", ml.checkIn(b1));

    assertFalse("Book was aleready checked in", ml.checkIn(b1));

In the first assert we expect the checkIn to return True (because checkin is succesful). If this would fail we would print a message like "book check in failed. Now in the second assert we expect the checkIn to fail, because the book was checked in already in the first line. So we expect a checkIn to return a False. If for some reason checkin returns a True (which we don't expect) than the message should never be "Book was already checked in", because the checkin was succesful.

You get that error because you haven't saved your file, save it for example "holamundo.py" then run it Ctrl + B

You can use :

composer self-update --2

To update to 2.0.8 version (Latest stable version)

If you have a remote configured and you have / don't care about losing some unpushed code, you can do :

git fetch && git reset --hard

Get the current task's user_struct

#define get_current_user()              \
({                                      \
    struct user_struct *__u;            \
    const struct cred *__cred;          \
    __cred = current_cred();            \
    __u = get_uid(__cred->user);        \
    __u;                                \
})

Pandas is based on NumPy arrays. The key to speed with NumPy arrays is to perform your operations on the whole array at once, never row-by-row or item-by-item.

For example, if close is a 1-d array, and you want the day-over-day percent change,

pct_change = close[1:]/close[:-1]

This computes the entire array of percent changes as one statement, instead of

pct_change = []
for row in close:
    pct_change.append(...)

So try to avoid the Python loop for i, row in enumerate(...) entirely, and think about how to perform your calculations with operations on the entire array (or dataframe) as a whole, rather than row-by-row.

Since it is in the directory data/, You need to do:

file path is '../../data/file.json'

$.getJSON('../../data/file.json', function(data) {         
    alert(data);
});

Pure JS:

   var request = new XMLHttpRequest();
   request.open("GET", "../../data/file.json", false);
   request.send(null)
   var my_JSON_object = JSON.parse(request.responseText);
   alert (my_JSON_object.result[0]);

I am seeing this error message when I run Firefox headless through selenium using xvfb. It turns out that the message was a red herring for me. The message is only a warning, not an error. It is not why Firefox was not starting correctly.

The reason that Firefox was not starting for me was that it had been updated to a version that was no longer compatible with the Selenium drivers that I was using. I upgraded the selenium drivers to the latest and Firefox starts up fine again (even with this warning message about RANDR).

New releases of Firefox are often only compatible with one or two versions of Selenium. Occasionally Firefox is released with NO compatible version of Selenium. When that happens, it may take a week or two for a new version of Selenium to get released. Because of this, I now keep a version of Firefox that is known to work with the version of Selenium that I have installed. In addition to the version of Firefox that is kept up to date by my package manager, I have a version installed in /opt/ (eg /opt/firefox31/). The Selenium Java API takes an argument for the location of the Firefox binary to be used. The downside is that older versions of Firefox have known security vulnerabilities and shouldn't be used with untrusted content.

This is not only a 'newbie' scenario. I just ran across this compiler message (GCC 5.4) when refactoring a class to remove some constructor parameters. I forgot to update both the declaration and definition, and the compiler spit out this unintuitive error.

The bottom line seems to be this: If the compiler can't match the definition's signature to the declaration's signature it thinks the definition is not a constructor and then doesn't know how to parse the code and displays this error. Which is also what happened for the OP: std::string is not the same type as string so the declaration's signature differed from the definition's and this message was spit out.

As a side note, it would be nice if the compiler looked for almost-matching constructor signatures and upon finding one suggested that the parameters didn't match rather than giving this message.

This works for me

$('ul.questions li a').click(function(event) {
    event.preventDefault();
    $('.tab').hide();
    window.location.hash = this.hash;
    $($(this).attr('href')).fadeIn('slow');
});

Check here http://jsbin.com/edicu for a demo with almost identical code

Yes, it is called Short-circuit Evaluation.

If the validity of the boolean statement can be assured after part of the statement, the rest is not evaluated.

This is very important when some of the statements have side-effects.

This is because the StreamReader closes the underlying stream automatically when being disposed of. The using statement does this automatically.

However, the StreamWriter you're using is still trying to work on the stream (also, the using statement for the writer is now trying to dispose of the StreamWriter, which is then trying to close the stream).

The best way to fix this is: don't use using and don't dispose of the StreamReader and StreamWriter. See this question.

using (var ms = new MemoryStream())
{
    var sw = new StreamWriter(ms);
    var sr = new StreamReader(ms);

    sw.WriteLine("data");
    sw.WriteLine("data 2");
    ms.Position = 0;

    Console.WriteLine(sr.ReadToEnd());                        
}

If you feel bad about sw and sr being garbage-collected without being disposed of in your code (as recommended), you could do something like that:

StreamWriter sw = null;
StreamReader sr = null;

try
{
    using (var ms = new MemoryStream())
    {
        sw = new StreamWriter(ms);
        sr = new StreamReader(ms);

        sw.WriteLine("data");
        sw.WriteLine("data 2");
        ms.Position = 0;

        Console.WriteLine(sr.ReadToEnd());                        
    }
}
finally
{
    if (sw != null) sw.Dispose();
    if (sr != null) sr.Dispose();
}

Define set

a = set()

Use add to append single values

a.add(1)
a.add(2)

Use update to add elements from tuples, sets, lists or frozen-sets

a.update([3,4])

>> print(a)
{1, 2, 3, 4}

If you want to add a tuple or frozen-set itself, use add

a.add((5, 6))

>> print(a)
{1, 2, 3, 4, (5, 6)}

Note: Since set elements must be hashable, and lists are considered mutable, you cannot add a list to a set. You also cannot add other sets to a set. You can however, add the elements from lists and sets as demonstrated with the ".update" method.

The simplest way to get an input box is with the Read-Host cmdlet and -AsSecureString parameter.

$us = Read-Host 'Enter Your User Name:' -AsSecureString
$pw = Read-Host 'Enter Your Password:' -AsSecureString

This is especially useful if you are gathering login info like my example above. If you prefer to keep the variables obfuscated as SecureString objects you can convert the variables on the fly like this:

[Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($us))
[Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($pw))

If the info does not need to be secure at all you can convert it to plain text:

$user = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($us))

Read-Host and -AsSecureString appear to have been included in all PowerShell versions (1-6) but I do not have PowerShell 1 or 2 to ensure the commands work identically. https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/read-host?view=powershell-3.0

another alternative is to use a form replacement script/library. They usually hide the original element and replace them with a div or span, which you can style in whatever way you like.

Examples are:

http://customformelements.net (based on mootools) http://www.htmldrive.net/items/show/481/jQuery-UI-Radiobutton-und-Checkbox-Replacement.html

Another way to do this now that we have Java 8 lambda expressions.

arrayList.removeIf(item -> item == null || "".equals(item));

//Write a javascript method to bind click event of each "li" item

    function BindClickEvent()
    {
    var selector = '.nav li';
    //Removes click event of each li
    $(selector ).unbind('click');
    //Add click event
    $(selector ).bind('click', function()
    {
        $(selector).removeClass('active');
        $(this).addClass('active');
    });

    }

//first call this method when first time when page load

    $( document ).ready(function() {
         BindClickEvent();
    });

//Call BindClickEvent method from server side

    protected void Page_Load(object sender, EventArgs e)
    {
        ScriptManager.RegisterStartupScript(Page,GetType(), Guid.NewGuid().ToString(),"BindClickEvent();",true);
    }

It wouldn't be wrong to mention that Pexpect does throw a similar error

#python -c "import pexpect; p=pexpect.spawn('/usr/local/ssl/bin/openssl_1.1.0f  version'); p.interact()"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python2.7/site-packages/pexpect.py", line 430, in __init__
    self._spawn (command, args)
  File "/usr/lib/python2.7/site-packages/pexpect.py", line 560, in _spawn
    os.execv(self.command, self.args)
OSError: [Errno 8] Exec format error

Over here, the openssl_1.1.0f file at the specified path has exec command specified in it and is running the actual openssl binary when called.

Usually, I wouldn't mention this unless I have the root cause, but this problem was not there earlier. Unable to find the similar problem, the closest explanation to make it work is the same as the one provided by @jfs above.

what worked for me is both

• adding /bin/bash at the beginning of the command or file you are
  facing the problem with, or
• adding shebang #!/bin/sh as the first line.

for ex.

#python -c "import pexpect; p=pexpect.spawn('/bin/bash /usr/local/ssl/bin/openssl_1.1.0f  version'); p.interact()"
OpenSSL 1.1.0f  25 May 2017

I had the same error message but the solution is different.

The compiler parses the file from top to bottom.

Make sure a struct is defined BEFORE using it into another:

typedef struct
{
    char name[50];
    wheel_t wheels[4]; //wrong, wheel_t is not defined yet
} car_t;

typedef struct
{
    int weight;
} wheel_t;

Base on @increddibelly answer, I applied to my query as below.

I share for whom concerned.

My table structure FamilyData(Id, nodeTime, totalEnergy)

select
   sum(totalEnergy) as TotalEnergy,
   DATEPART ( week, nodeTime ) as weeknr
from FamilyData
group by DATEPART (week, nodeTime)

No JavaScript needed. Just add the class .row-eq-height to your existing .row just like this:

<div class="row row-eq-height">
  <div class="col-xs-12 col-sm-4 panel" style="background-color: red">
    some content
  </div>
  <div class="col-xs-6 col-sm-4 panel" style="background-color: yellow">
    kittenz
  <img src="http://placekitten.com/100/100">
  </div>
  <div class="col-xs-6 col-sm-4 panel" style="background-color: blue">
    some more content
  </div>
</div>

Tip: if you have more than 12 columns in your row, the bootstrap grid will fail to wrap it. So add a new div.row.row-eq-height each 12 columns.

Tip: you may need to add

<link rel="stylesheet" href="http://getbootstrap.com.vn/examples/equal-height-columns/equal-height-columns.css" />

to your html

Here's a more complete and flexible example that doesn't omit necessary includes to generate compilation errors:

#include <iostream>
#include <unordered_map>

class Hashtable {
    std::unordered_map<const void *, const void *> htmap;

public:
    void put(const void *key, const void *value) {
            htmap[key] = value;
    }

    const void *get(const void *key) {
            return htmap[key];
    }

};

int main() {
    Hashtable ht;
    ht.put("Bob", "Dylan");
    int one = 1;
    ht.put("one", &one);
    std::cout << (char *)ht.get("Bob") << "; " << *(int *)ht.get("one");
}

Still not particularly useful for keys, unless they are predefined as pointers, because a matching value won't do! (However, since I normally use strings for keys, substituting "string" for "const void *" in the declaration of the key should resolve this problem.)

You can use this code

var str="test_String_ABC";_x000D_
var strReplacedWith=" and ";_x000D_
var currentIndex = str.lastIndexOf("_");_x000D_
str = str.substring(0, currentIndex) + strReplacedWith + str.substring(currentIndex + 1, str.length);_x000D_
_x000D_
alert(str);

There's two standard library ways to find the most frequent value in a list:

statistics.mode:

from statistics import mode
most_common = mode([3, 2, 2, 2, 1, 1])  # 2
most_common = mode([3, 2])  # StatisticsError: no unique mode

• Raises an exception if there's no unique most frequent value
• Only returns single most frequent value

collections.Counter.most_common:

from collections import Counter
most_common, count = Counter([3, 2, 2, 2, 1, 1]).most_common(2)  # 2, 3
(most_common_1, count_1), (most_common_2, count_2) = Counter([3, 2, 2]).most_common(2)  # (2, 2), (3, 1)

• Can return multiple most frequent values
• Returns element count as well

So in the case of the question, the second one would be the right choice. As a side note, both are identical in terms of performance.

This one worked for me:

(?P<value>[-+]*\d+\.\d+|[-+]*\d+)

You can also use this one (without named parameter):

([-+]*\d+\.\d+|[-+]*\d+)

Use some online regex tester to test it (e.g. regex101 )

Simply add Templates URL:

<a href="{% url 'service_data' d.id %}">
 ...XYZ
</a>

Used in django 2.0

The derived table would work, but if this is SQL 2005, a CTE and ROW_NUMBER might be cleaner:

WITH UserStatus (User, Date, Status, Notes, Ord)
as
(
SELECT Date, User, Status, Notes, 
     ROW_NUMBER() OVER (PARTITION BY User ORDER BY Date DESC)
FROM [SOMETABLE]
)

SELECT User, Date, Status, Notes from UserStatus where Ord = 1

This would also facilitate the display of the most recent x statuses from each user.

For me, only "Integer.toHexString(registered)" worked the way I wanted:

char registered = '®';
System.out.println("Answer:"+Integer.toHexString(registered));

This answer will give you only string representations what are usually presented in the tables. Jon Skeet's answer explains more.

Here's an overview of the parameters to the map(function, *sequences) function:

• function is the name of your function.
• sequences is any number of sequences, which are usually lists or tuples. map will iterate over them simultaneously and give the current values to function. That's why the number of sequences should equal the number of parameters to your function.

It sounds like you're trying to iterate for some of function's parameters but keep others constant, and unfortunately map doesn't support that. I found an old proposal to add such a feature to Python, but the map construct is so clean and well-established that I doubt something like that will ever be implemented.

Use a workaround like global variables or list comprehensions, as others have suggested.

Merging even more with Pedro Lopez's answer,

I added this to my ngGoogleAnalytis module(which I reuse in many apps):

var base = $('base').attr('href').replace(/\/$/, "");

in this case, I have a tag in my index link:

  <base href="/store/">

it's useful when using html5 mode on angular.js v1.3

(remove the replace() function call if your base tag doesn't finish with a slash /)

angular.module("ngGoogleAnalytics", []).run(['$rootScope', '$location', '$window',
    function($rootScope, $location, $window) {
      $rootScope.$on('$routeChangeSuccess',
        function(event) {
          if (!$window.ga) { return; }
          var base = $('base').attr('href').replace(/\/$/, "");

          $window.ga('send', 'pageview', {
            page: base + $location.path()
          });
        }
      );
    }
  ]);

If the adapter is already set, setting it again will not refresh the listview. Instead first check if the listview has a adapter and then call the appropriate method.

I think its not a very good idea to create a new instance of the adapter while setting the list view. Instead, create an object.

BuildingAdapter adapter = new BuildingAdapter(context);

    if(getListView().getAdapter() == null){ //Adapter not set yet.
     setListAdapter(adapter);
    }
    else{ //Already has an adapter
    adapter.notifyDataSetChanged();
    }

Also you might try to run the refresh list on UI Thread:

activity.runOnUiThread(new Runnable() {         
        public void run() {
              //do your modifications here

              // for example    
              adapter.add(new Object());
              adapter.notifyDataSetChanged()  
        }
});

If you have killall:

os.system("killall -9 iChat");

Or:

os.system("ps -C iChat -o pid=|xargs kill -9")

I have used Netbeans for java, and it works great. Not sure how it works with C++, though.

Inline function is the optimization technique used by the compilers. One can simply prepend inline keyword to function prototype to make a function inline. Inline function instruct compiler to insert complete body of the function wherever that function got used in code.

Advantages :-

1. It does not require function calling overhead.

2. It also save overhead of variables push/pop on the stack, while function calling.

3. It also save overhead of return call from a function.

4. It increases locality of reference by utilizing instruction cache.

5. After in-lining compiler can also apply intra-procedural optimization if specified. This is the most important one, in this way compiler can now focus on dead code elimination, can give more stress on branch prediction, induction variable elimination etc..

To check more about it one can follow this link http://tajendrasengar.blogspot.com/2010/03/what-is-inline-function-in-cc.html

Number((6.688689).toFixed(1)); // 6.7

var number = 6.688689;
var roundedNumber = Math.round(number * 10) / 10;

Use toFixed() function.

(6.688689).toFixed(); // equal to "7"
(6.688689).toFixed(1); // equal to "6.7"
(6.688689).toFixed(2); // equal to "6.69"

In android-N, this feature is included in it. check Number-blocking update for android N

Android N now supports number-blocking in the platform and provides a framework API to let service providers maintain a blocked-number list. The default SMS app, the default phone app, and provider apps can read from and write to the blocked-number list. The list is not accessible to other app.

advantage of are:

1. Numbers blocked on calls are also blocked on texts
2. Blocked numbers can persist across resets and devices through the Backup & Restore feature
3. Multiple apps can use the same blocked numbers list

For more information, see android.provider.BlockedNumberContract

Update an existing project.

To compile your app against the Android N platform, you need to use the Java 8 Developer Kit (JDK 8), and in order to use some tools with Android Studio 2.1, you need to install the Java 8 Runtime Environment (JRE 8).

Open the build.gradle file for your module and update the values as follows:

android {
  compileSdkVersion 'android-N'
  buildToolsVersion 24.0.0 rc1
  ...

  defaultConfig {
     minSdkVersion 'N'
     targetSdkVersion 'N'
     ...
  }
  ...
}

Your code was compiled with Java 8.

Either compile your code with an older JDK (compliance level) or run it on a Java 8 JRE.

Hope this helps...

Use find for name "a" and execute rm to remove those named according to your wishes, as follows:

find . -name a -exec rm -rf {} \;

Test it first using ls to list:

find . -name a -exec ls {} \;

To ensure this only removes directories and not plain files, use the "-type d" arg (as suggested in the comments):

find . -name a -type d -exec rm -rf {} \;

The "{}" is a substitution for each file "a" found - the exec command is executed against each by substitution.

The function below doesn't have an issue with the length of arrays and performs better than all suggested solutions:

function pushArray(list, other) {
    var len = other.length;
    var start = list.length;
    list.length = start + len;
    for (var i = 0; i < len; i++ , start++) {
        list[start] = other[i];
    }
}

unfortunately, jspref refuses to accept my submissions, so here they are the results using benchmark.js

        Name            |   ops/sec   |  ± %  | runs sampled
for loop and push       |      177506 |  0.92 | 63
Push Apply              |      234280 |  0.77 | 66

set length and for loop |      284223 |  0.41 | 66

where

for loop and push is:

    for (var i = 0, l = source.length; i < l; i++) {
        target.push(source[i]);
    }

Push Apply:

target.push.apply(target, source);

spread operator:

    target.push(...source);

and finally the 'set length and for loop' is the above function

Here is my take on this problem. Here is the short version:

function arrayContains() {
        local haystack=${!1}
        local needle="$2"
        printf "%s\n" ${haystack[@]} | grep -q "^$needle$"
}

And the long version, which I think is much easier on the eyes.

# With added utility function.
function arrayToLines() {
        local array=${!1}
        printf "%s\n" ${array[@]}
}

function arrayContains() {
        local haystack=${!1}
        local needle="$2"
        arrayToLines haystack[@] | grep -q "^$needle$"
}

Examples:

test_arr=("hello" "world")
arrayContains test_arr[@] hello; # True
arrayContains test_arr[@] world; # True
arrayContains test_arr[@] "hello world"; # False
arrayContains test_arr[@] "hell"; # False
arrayContains test_arr[@] ""; # False

99% of the time I would use XMLHttpRequest or fetch for something like this. However, there's an alternative solution which doesn't require javascript...

You could include a hidden iframe on your page and set the target attribute of your form to point to that iframe.

<style>
  .hide { position:absolute; top:-1px; left:-1px; width:1px; height:1px; }
</style>

<iframe name="hiddenFrame" class="hide"></iframe>

<form action="receiver.pl" method="post" target="hiddenFrame">
  <input name="signed" type="checkbox">
  <input value="Save" type="submit">
</form>

There are very few scenarios where I would choose this route. Generally handling it with javascript is better because, with javascript you can...

• gracefully handle errors (e.g. retry)
• provide UI indicators (e.g. loading, processing, success, failure)
• run logic before the request is sent, or run logic after the response is received.

This not the same case as in the question, but might be helpful for someone facing the similar issue. On Windows, if you are calling npm commands from some CI/automation tool, you might run into the error:

Error: Cannot find module 'SOME_PATH\node_modules\npm\bin\npm-cli.js'

where SOME_PATH is not Program Files/... but some project directory instead. So npm tries to find npm-cli.js inside the project root directory instead of searching it in Program Files/nodejs.

The reason is npm.cmd script:

:: Created by npm, please don't edit manually.
@ECHO OFF

SETLOCAL

SET "NODE_EXE=%~dp0\node.exe"
IF NOT EXIST "%NODE_EXE%" (
  SET "NODE_EXE=node"
)


SET "NPM_CLI_JS=%~dp0\node_modules\npm\bin\npm-cli.js"
FOR /F "delims=" %%F IN ('CALL "%NODE_EXE%" "%NPM_CLI_JS%" prefix -g') DO (
  SET "NPM_PREFIX_NPM_CLI_JS=%%F\node_modules\npm\bin\npm-cli.js"
)
IF EXIST "%NPM_PREFIX_NPM_CLI_JS%" (
  SET "NPM_CLI_JS=%NPM_PREFIX_NPM_CLI_JS%"
)

"%NODE_EXE%" "%NPM_CLI_JS%" %*

This script uses %~dp0 to lookup the npm-cli.js but some automation tools could set work directory in the way that %~dp0 points to the local project dir so the script works incorrectly.

One possible solution could be changing the npm calls from this

npm.cmd install

to this

cmd.exe /c npm.cmd install

get-aduser -Server "servername" -Identity %username% -Properties *

get-aduser -Server "testdomain.test.net" -Identity testuser -Properties *

These work when you have the username. Also less to type than using the -filter property.

EDIT: Formatting.

To avoid deprecated opts and theme_rect use:

myplot + theme(panel.background = element_rect(fill='green', colour='red'))

To define your own custom theme, based on theme_gray but with some of your changes and a few added extras including control of gridline colour/size (more options available to play with at ggplot2.org):

theme_jack <- function (base_size = 12, base_family = "") {
    theme_gray(base_size = base_size, base_family = base_family) %+replace% 
        theme(
            axis.text = element_text(colour = "white"),
            axis.title.x = element_text(colour = "pink", size=rel(3)),
            axis.title.y = element_text(colour = "blue", angle=45),
            panel.background = element_rect(fill="green"),
            panel.grid.minor.y = element_line(size=3),
            panel.grid.major = element_line(colour = "orange"),
            plot.background = element_rect(fill="red")
    )   
}

To make your custom theme the default when ggplot is called in future, without masking:

theme_set(theme_jack())

If you want to change an element of the currently set theme:

theme_update(plot.background = element_rect(fill="pink"), axis.title.x = element_text(colour = "red"))

To store the current default theme as an object:

theme_pink <- theme_get()

Note that theme_pink is a list whereas theme_jack was a function. So to return the theme to theme_jack use theme_set(theme_jack()) whereas to return to theme_pink use theme_set(theme_pink).

You can replace theme_gray by theme_bw in the definition of theme_jack if you prefer. For your custom theme to resemble theme_bw but with all gridlines (x, y, major and minor) turned off:

theme_nogrid <- function (base_size = 12, base_family = "") {
    theme_bw(base_size = base_size, base_family = base_family) %+replace% 
        theme(
            panel.grid = element_blank()
    )   
}

Finally a more radical theme useful when plotting choropleths or other maps in ggplot, based on discussion here but updated to avoid deprecation. The aim here is to remove the gray background, and any other features that might distract from the map.

theme_map <- function (base_size = 12, base_family = "") {
    theme_gray(base_size = base_size, base_family = base_family) %+replace% 
        theme(
            axis.line=element_blank(),
            axis.text.x=element_blank(),
            axis.text.y=element_blank(),
            axis.ticks=element_blank(),
            axis.ticks.length=unit(0.3, "lines"),
            axis.ticks.margin=unit(0.5, "lines"),
            axis.title.x=element_blank(),
            axis.title.y=element_blank(),
            legend.background=element_rect(fill="white", colour=NA),
            legend.key=element_rect(colour="white"),
            legend.key.size=unit(1.2, "lines"),
            legend.position="right",
            legend.text=element_text(size=rel(0.8)),
            legend.title=element_text(size=rel(0.8), face="bold", hjust=0),
            panel.background=element_blank(),
            panel.border=element_blank(),
            panel.grid.major=element_blank(),
            panel.grid.minor=element_blank(),
            panel.margin=unit(0, "lines"),
            plot.background=element_blank(),
            plot.margin=unit(c(1, 1, 0.5, 0.5), "lines"),
            plot.title=element_text(size=rel(1.2)),
            strip.background=element_rect(fill="grey90", colour="grey50"),
            strip.text.x=element_text(size=rel(0.8)),
            strip.text.y=element_text(size=rel(0.8), angle=-90) 
        )   
}

As this page also lists alternative tools I'll mention xpdf which has command line tools ready compiled for Linux/Windows/Mac. Supports transparency. Is free for commercial use - opposed to Ghostscript which has truly outrageous pricing.

In a test on a huge PDF file it was 7.5% faster than Ghostscript.

(It also has PDF to text and HTML converters)

In Ruby, converting to lowercase and stripping everything not alphabetic:

def isPalindrome( string )
    ( test = string.downcase.gsub( /[^a-z]/, '' ) ) == test.reverse
end

But that feels like cheating, right? No pointers or anything! So here's a C version too, but without the lowercase and character stripping goodness:

#include <stdio.h>
int isPalindrome( char * string )
{
    char * i = string;
    char * p = string;
    while ( *++i ); while ( i > p && *p++ == *--i );
    return i <= p && *i++ == *--p;
}
int main( int argc, char **argv )
{
    if ( argc != 2 )
    {
        fprintf( stderr, "Usage: %s <word>\n", argv[0] );
        return -1;
    }
    fprintf( stdout, "%s\n", isPalindrome( argv[1] ) ? "yes" : "no" );
    return 0;
}

Well, that was fun - do I get the job ;^)

you can also use following command on client

cmd :: config set requirepass p@ss$12E45

above command will set p@ss$12E45 as a redis server password.

In pydev eclipse plugin, you may want to set the environment variable for DYLD. The path can be set as shown in

One line of code in kotlin:

getSharedPreferences("MY_PREFS_NAME", MODE_PRIVATE).edit().clear().apply()

parseDouble returns a primitive double containing the value of the string:

Returns a new double initialized to the value represented by the specified String, as performed by the valueOf method of class Double.

valueOf returns a Double instance, if already cached, you'll get the same cached instance.

Returns a Double instance representing the specified double value. If a new Double instance is not required, this method should generally be used in preference to the constructor Double(double), as this method is likely to yield significantly better space and time performance by caching frequently requested values.

To avoid the overhead of creating a new Double object instance, you should normally use valueOf

I've got a handy extension method that uses TryParse, as IsDefined is case-sensitive.

public static bool IsParsable<T>(this string value) where T : struct
{
    return Enum.TryParse<T>(value, true, out _);
}

If you want upload big size image or data in database. Just change the data type to 'BIG BLOB'.

You can create your own simple unsafe html binding, of course if you use user input it could be a security risk.

App.directive('simpleHtml', function() {
  return function(scope, element, attr) {
    scope.$watch(attr.simpleHtml, function (value) {
      element.html(scope.$eval(attr.simpleHtml));
    })
  };
})

Microsoft: Because VBScript is a subset of Visual Basic for Applications,...

The code below is derived from Codo's post should it also be helpful to have in class form, and usable as VBScript:

class JsonParser
    ' adapted from: http://stackoverflow.com/questions/6627652/parsing-json-in-excel-vba
    private se
    private sub Class_Initialize
        set se = CreateObject("MSScriptControl.ScriptControl") 
        se.Language = "JScript"
        se.AddCode "function getValue(jsonObj, valueName) { return jsonObj[valueName]; } "
        se.AddCode "function enumKeys(jsonObj) { var keys = new Array(); for (var i in jsonObj) { keys.push(i); } return keys; } "
    end sub
    public function Decode(ByVal json)
        set Decode = se.Eval("(" + cstr(json) + ")")
    end function

    public function GetValue(ByVal jsonObj, ByVal valueName)
        GetValue = se.Run("getValue", jsonObj, valueName)
    end function

    public function GetObject(ByVal jsonObject, ByVal valueName)
        set GetObjet = se.Run("getValue", jsonObject, valueName)
    end function

    public function EnumKeys(ByVal jsonObject)
        dim length, keys, obj, idx, key
        set obj = se.Run("enumKeys", jsonObject)
        length = GetValue(obj, "length")
        redim keys(length - 1)
        idx = 0
        for each key in obj
            keys(idx) = key
            idx = idx + 1
        next
        EnumKeys = keys
    end function
end class

Usage:

set jp = new JsonParser
set jo = jp.Decode("{value: true}")
keys = jp.EnumKeys(jo)
value = jp.GetValue(jo, "value")

Success!

After checking the log files and making sure the permissions on php_openssl.dll were correct, I googled the warning and found more things to try.

So I:

• added C:\PHP\ext to the Windows path
• added libeay32.dll and ssleay32.dll to C:\WINDOWS\system32\inetsrv
• rebooted the server

I'm not sure which of these fixed my problem, but it's definately fixed now! :)

I found these things to try on this page: http://php.net/manual/en/install.windows.extensions.php

Thanks for your help!

If you want to run some custom filter logic you can create a function which takes the array element as an argument and returns true or false based on whether it should be in the search results. Then pass it to the filter instruction just like you do with the search object, for example:

JS:

$scope.filterFn = function(car)
{
    // Do some tests

    if(car.carDetails.doors > 2)
    {
        return true; // this will be listed in the results
    }

    return false; // otherwise it won't be within the results
};

HTML:

...
<article data-ng-repeat="result in results | filter:search | filter:filterFn" class="result">
...

As you can see you can chain many filters together, so adding your custom filter function doesn't force you to remove the previous filter using the search object (they will work together seamlessly).

You might be able to use the following for decoding, compressing and saving an image:

     @Override
     public void onClick(View view) {
                onItemSelected1();
                InputStream image_stream = null;
                try {
                    image_stream = getContentResolver().openInputStream(myUri);
                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                }

                Bitmap image= BitmapFactory.decodeStream(image_stream );
                // path to sd card
                File path=Environment.getExternalStorageDirectory();
                //create a file
                File  dir=new File(path+"/ComDec/");
                dir.mkdirs();
                Date date=new Date();
                File file=new File(dir,date+".jpg");

                OutputStream out=null;
                try{
                    out=new FileOutputStream(file);
                    image.compress(format,size,out);
                    out.flush();
                    out.close();


                    MediaStore.Images.Media.insertImage(getContentResolver(), image," yourTitle "," yourDescription");

                    image=null;


                }
                catch (IOException e)
                {
                    e.printStackTrace();
                }
                Toast.makeText(SecondActivity.this,"Image Save Successfully",Toast.LENGTH_LONG).show();
            }
        });

Here’s some PHP and JavaScript demonstration code that shows a simple way to create indexed fields on a form (fields that have the same name) and then process them in both JavaScript and PHP. The fields must have both "ID" names and "NAME" names. Javascript uses the ID and PHP uses the NAME.

<?php
// How to use same field name multiple times on form
// Process these fields in Javascript and PHP
// Must use "ID" in Javascript and "NAME" in PHP 
echo "<HTML>";
echo "<HEAD>";
?>
<script type="text/javascript">
function TestForm(form) {
// Loop through the HTML form field (TheId) that is returned as an array. 
// The form field has multiple (n) occurrences on the form, each which has the same name.
// This results in the return of an array of elements indexed from 0 to n-1.
// Use ID  in Javascript
var i = 0;
document.write("<P>Javascript responding to your button click:</P>");
for (i=0; i < form.TheId.length; i++) {
  document.write(form.TheId[i].value);
  document.write("<br>");
}  
}
</script>
<?php
echo "</HEAD>";
echo "<BODY>";
$DQ = '"';  # Constant for building string with double quotes in it.

if (isset($_POST["MyButton"])) {
  $TheNameArray = $_POST["TheName"];  # Use NAME in PHP
  echo "<P>Here are the names you submitted to server:</P>";
  for ($i = 0; $i <3; $i++) {   
    echo $TheNameArray[$i] . "<BR>";
  } 
}
echo "<P>Enter names and submit to server or Javascript</P>";
echo "<FORM NAME=TstForm METHOD=POST ACTION=" ;
echo $DQ . "TestArrayFormToJavascript2.php" . $DQ . "OnReset=" . $DQ . "return allowreset(this)" . $DQ . ">";
echo "<FORM>";
echo "<INPUT ID = TheId NAME=" . $DQ . "TheName[]" . $DQ . " VALUE=" . $DQ . "" . $DQ . ">";
echo "<INPUT ID = TheId NAME=" . $DQ . "TheName[]" . $DQ . " VALUE=" . $DQ . "" . $DQ . ">";
echo "<INPUT ID = TheId NAME=" . $DQ . "TheName[]" . $DQ . " VALUE=" . $DQ . "" . $DQ . ">";
echo "<P><INPUT TYPE=submit NAME=MyButton VALUE=" . $DQ . "Submit to server"    . $DQ . "></P>";
echo "<P><BUTTON onclick=" . $DQ . "TestForm(this.form)" . $DQ . ">Submit to Javascript</BUTTON></P>"; 
echo "</FORM>";
echo "</BODY>";
echo "</HTML>";

Here's a stdlib solution that supports a variable utc offset in the input time string:

>>> from email.utils import parsedate_tz, mktime_tz
>>> from datetime import datetime, timedelta
>>> timestamp = mktime_tz(parsedate_tz('Tue May 08 15:14:45 +0800 2012'))
>>> utc_time = datetime(1970, 1, 1) + timedelta(seconds=timestamp)
>>> utc_time
datetime.datetime(2012, 5, 8, 7, 14, 45)

1. SOAP Web Services are standard-based and supported by almost every software platform: They rely heavily in XML and have support for transactions, security, asynchronous messages and many other issues. It’s a pretty big and complicated standard, but covers almost every messaging situation. On the other side, RESTful services relies of HTTP protocol and verbs (GET, POST, PUT, DELETE) to interchange messages in any format, preferable JSON and XML. It’s a pretty simple and elegant architectural approach.
2. As in every topic in the Java World, there are several libraries to build/consume Web Services. In the SOAP Side you have the JAX-WS standard and Apache Axis, and in REST you can use Restlets or Spring REST Facilities among other libraries.

With question 3, this article states that RESTful Services are appropiate in this scenarios:

• If you have limited bandwidth
• If your operations are stateless: No information is preserved from one invocation to the next one, and each request is treated independently.
• If your clients require caching.

While SOAP is the way to go when:

• If you require asynchronous processing
• If you need formal contract/Interfaces
• In your service operations are stateful: For example, you store information/data on a request and use that stored data on the next one.

Does your upload die at the very end? 99% before crashing? Client body and buffers are key because nginx must buffer incoming data. The body configs (data of the request body) specify how nginx handles the bulk flow of binary data from multi-part-form clients into your app's logic.

The clean setting frees up memory and consumption limits by instructing nginx to store incoming buffer in a file and then clean this file later from disk by deleting it.

Set body_in_file_only to clean and adjust buffers for the client_max_body_size. The original question's config already had sendfile on, increase timeouts too. I use the settings below to fix this, appropriate across your local config, server, & http contexts.

client_body_in_file_only clean;
client_body_buffer_size 32K;

client_max_body_size 300M;

sendfile on;
send_timeout 300s;

I had this problem when trying to run Rails in a subdirectory, and not in /. For example, I had Angular/Node/Gulp app running in /client and a Rails app running in /server, but both of them were in the same git repo, so I could track changes across the front end and back end. I got this error when trying to deploy them to Heroku. For anyone else having this issue, here is a custom buildpack that will allow running Rails in a subdirectory.

Another route you can take is Ofelia, which is a highly configurable task runner image that allows 4 modes of execution.

job-exec: this job is executed inside of a running container.
job-run: runs a command inside of a new container, using a specific image.
job-local: runs the command inside of the host running ofelia.
job-service-run: runs the command inside a new "run-once" service, for running inside a swarm

The advantage here is that somebody else has done all the heavy lifting for you. Super convenient and easy.

It also has a spiffy official mascot.

I prefer to use WebClient, it seems to handle SSL transparently:

Put your script in a file foo.py starting with

#!/usr/bin/python

Then give execute permission to that script using

chmod a+x foo.py

and use the full path of your foo.py file in your crontab.

See documentation of execve(2) which is handling the shebang.

Paul H's answer is right that you will have to make a second groupby object, but you can calculate the percentage in a simpler way -- just groupby the state_office and divide the sales column by its sum. Copying the beginning of Paul H's answer:

# From Paul H
import numpy as np
import pandas as pd
np.random.seed(0)
df = pd.DataFrame({'state': ['CA', 'WA', 'CO', 'AZ'] * 3,
                   'office_id': list(range(1, 7)) * 2,
                   'sales': [np.random.randint(100000, 999999)
                             for _ in range(12)]})
state_office = df.groupby(['state', 'office_id']).agg({'sales': 'sum'})
# Change: groupby state_office and divide by sum
state_pcts = state_office.groupby(level=0).apply(lambda x:
                                                 100 * x / float(x.sum()))

Returns:

                     sales
state office_id

Can someone help me with the exact syntax?

It's a three-step process, and it involves modifying the openssl.cnf file. You might be able to do it with only command line options, but I don't do it that way.

Find your openssl.cnf file. It is likely located in /usr/lib/ssl/openssl.cnf:

$ find /usr/lib -name openssl.cnf
/usr/lib/openssl.cnf
/usr/lib/openssh/openssl.cnf
/usr/lib/ssl/openssl.cnf

On my Debian system, /usr/lib/ssl/openssl.cnf is used by the built-in openssl program. On recent Debian systems it is located at /etc/ssl/openssl.cnf

You can determine which openssl.cnf is being used by adding a spurious XXX to the file and see if openssl chokes.

First, modify the req parameters. Add an alternate_names section to openssl.cnf with the names you want to use. There are no existing alternate_names sections, so it does not matter where you add it.

[ alternate_names ]

DNS.1        = example.com
DNS.2        = www.example.com
DNS.3        = mail.example.com
DNS.4        = ftp.example.com

Next, add the following to the existing [ v3_ca ] section. Search for the exact string [ v3_ca ]:

subjectAltName      = @alternate_names

You might change keyUsage to the following under [ v3_ca ]:

keyUsage = digitalSignature, keyEncipherment

digitalSignature and keyEncipherment are standard fare for a server certificate. Don't worry about nonRepudiation. It's a useless bit thought up by computer science guys/gals who wanted to be lawyers. It means nothing in the legal world.

In the end, the IETF (RFC 5280), browsers and CAs run fast and loose, so it probably does not matter what key usage you provide.

Second, modify the signing parameters. Find this line under the CA_default section:

# Extension copying option: use with caution.
# copy_extensions = copy

And change it to:

# Extension copying option: use with caution.
copy_extensions = copy

This ensures the SANs are copied into the certificate. The other ways to copy the DNS names are broken.

Third, generate your self-signed certificate:

$ openssl genrsa -out private.key 3072
$ openssl req -new -x509 -key private.key -sha256 -out certificate.pem -days 730
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
...

Finally, examine the certificate:

$ openssl x509 -in certificate.pem -text -noout

Unfortunately PL/SQL doesn't have IF EXISTS operator like SQL Server. But you can do something like this:

begin
  for x in ( select count(*) cnt
               from dual 
              where exists (
                select 1 from courseoffering co
                  join co_enrolment ce on ce.co_id = co.co_id
                 where ce.s_regno = 403 
                   and ce.coe_completionstatus = 'C' 
                   and co.c_id = 803 ) )
  loop
        if ( x.cnt = 1 ) 
        then
           dbms_output.put_line('exists');
        else 
           dbms_output.put_line('does not exist');
        end if;
  end loop;
end;

RabbitMQ is a solid, general-purpose message broker that supports several protocols such as AMQP, MQTT, STOMP, etc. It can handle high throughput. A common use case for RabbitMQ is to handle background jobs or long-running task, such as file scanning, image scaling or PDF conversion. RabbitMQ is also used between microservices, where it serves as a means of communicating between applications, avoiding bottlenecks passing messages.

Kafka is a message bus optimized for high-throughput ingestion data streams and replay. Use Kafka when you have the need to move a large amount of data, process data in real-time or analyze data over a time period. In other words, where data need to be collected, stored, and handled. An example is when you want to track user activity on a webshop and generate suggested items to buy. Another example is data analysis for tracking, ingestion, logging or security.

Kafka can be seen as a durable message broker where applications can process and re-process streamed data on disk. Kafka has a very simple routing approach. RabbitMQ has better options if you need to route your messages in complex ways to your consumers. Use Kafka if you need to support batch consumers that could be offline or consumers that want messages at low latency. 

In order to understand how to read data from Kafka, we first need to understand its consumers and consumer groups. Partitions allow you to parallelize a topic by splitting the data across multiple nodes. Each record in a partition is assigned and identified by its unique offset. This offset points to the record in a partition. In the latest version of Kafka, Kafka maintains a numerical offset for each record in a partition. A consumer in Kafka can either automatically commit offsets periodically, or it can choose to control this committed position manually. RabbitMQ will keep all states about consumed/acknowledged/unacknowledged messages. I find Kafka more complex to understand than the case of RabbitMQ, where the message is simply removed from the queue once it's acked.

RabbitMQ's queues are fastest when they're empty, while Kafka retains large amounts of data with very little overhead - Kafka is designed for holding and distributing large volumes of messages. (If you plan to have very long queues in RabbitMQ you could have a look at lazy queues.)

Kafka is built from the ground up with horizontal scaling (scale by adding more machines) in mind, while RabbitMQ is mostly designed for vertical scaling (scale by adding more power).

RabbitMQ has a built-in user-friendly interface that lets you monitor and handle your RabbitMQ server from a web browser. Among other things, queues, connections, channels, exchanges, users and user permissions can be handled - created, deleted and listed in the browser and you can monitor message rates and send/receive messages manually. Kafka has a number of open-source tools, and also some commercial once, offering the administration and monitoring functionalities. I would say that it's easier/gets faster to get a good understanding of RabbitMQ.

In general, if you want a simple/traditional pub-sub message broker, the obvious choice is RabbitMQ, as it will most probably scale more than you will ever need it to scale. I would have chosen RabbitMQ if my requirements were simple enough to deal with system communication through channels/queues, and where retention and streaming is not a requirement.

There are two main situations where I would choose RabbitMQ; For long-running tasks, when I need to run reliable background jobs. And for communication and integration within, and between applications, i.e as middleman between microservices; where a system simply needs to notify another part of the system to start to work on a task, like ordering handling in a webshop (order placed, update order status, send order, payment, etc.).

In general, if you want a framework for storing, reading (re-reading), and analyzing streaming data, use Apache Kafka. It’s ideal for systems that are audited or those that need to store messages permanently. These can also be broken down into two main use cases for analyzing data (tracking, ingestion, logging, security etc.) or real-time processing.

More reading, use cases and some comparison data can be found here: https://www.cloudamqp.com/blog/2019-12-12-when-to-use-rabbitmq-or-apache-kafka.html

Also recommending the industry paper: "Kafka versus RabbitMQ: A comparative study of two industry reference publish/subscribe implementations": http://dl.acm.org/citation.cfm?id=3093908

I do work at a company providing both Apache Kafka and RabbitMQ as a Service.

I'd do it like this:

Get-ChildItem -Path $folder -r  | 
          ? { $_.PsIsContainer -and $_.FullName -notmatch 'archive' }

One easy solution is to use HTML entities instead of actual characters. For example, the "[email protected]" will be converted into :

<a href="&#109;&#97;&#105;&#108;&#116;&#111;&#58;&#109;&#101;&#64;&#101;&#120;&#97;&#109;&#112;&#108;&#101;&#46;&#99;&#111;&#109;">email me</A>

exit code 139 (people say this means memory fragmentation)

No, it means that your program died with signal 11 (SIGSEGV on Linux and most other UNIXes), also known as segmentation fault.

Could anybody tell me why the run fails but debug doesn't?

Your program exhibits undefined behavior, and can do anything (that includes appearing to work correctly sometimes).

Your first step should be running this program under Valgrind, and fixing all errors it reports.

If after doing the above, the program still crashes, then you should let it dump core (ulimit -c unlimited; ./a.out) and then analyze that core dump with GDB: gdb ./a.out core; then use where command.

const setAttributes = (el, attrs) =>
  Object.entries(attrs)
    .forEach(args =>
      el.setAttribute(...args))

Deep copy literally performs a deep copy. It means, that if your class has some fields that are references, their values will be copied, not references themselves. If, for example you have two instances of a class, A & B with fields of reference type, and perform a deep copy, changing a value of that field in A won't affect a value in B. And vise-versa. Things are different with shallow copy, because only references are copied, therefore, changing this field in a copied object would affect the original object.

What type of a copy does a copy constructor does?

It is implementation - dependent. This means that there are no strict rules about that, you can implement it like a deep copy or shallow copy, however as far as i know it is a common practice to implement a deep copy in a copy constructor. A default copy constructor performs a shallow copy though.

You can map the alphabet to a list and return the index of each one as per the below :

import string

alphabet=string.ascii_lowercase
#alphabet='abcdefghijklmnopqrstuvwxyz'

#Get the character index , ex: e  
print(chars.find('e'))
#This will return 4

I also struggled finding articles on how to just generate the token part. I never found one and wrote my own. So if it helps:

The things to do are:

• Create a new web application
• Install the following NuGet packages:
  • Microsoft.Owin
  • Microsoft.Owin.Host.SystemWeb
  • Microsoft.Owin.Security.OAuth
  • Microsoft.AspNet.Identity.Owin
• Add a OWIN startup class

Then create a HTML and a JavaScript (index.js) file with these contents:

var loginData = 'grant_type=password&[email protected]&password=test123';

var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function () {
    if (xmlhttp.readyState === 4 && xmlhttp.status === 200) {
        alert(xmlhttp.responseText);
    }
}
xmlhttp.open("POST", "/token", true);
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.send(loginData);

<!DOCTYPE html>
<html>
<head>
    <title></title>
</head>
<body>
    <script type="text/javascript" src="index.js"></script>
</body>
</html>

The OWIN startup class should have this content:

using System;
using System.Security.Claims;
using Microsoft.Owin;
using Microsoft.Owin.Security.OAuth;
using OAuth20;
using Owin;

[assembly: OwinStartup(typeof(Startup))]

namespace OAuth20
{
    public class Startup
    {
        public static OAuthAuthorizationServerOptions OAuthOptions { get; private set; }

        public void Configuration(IAppBuilder app)
        {
            OAuthOptions = new OAuthAuthorizationServerOptions()
            {
                TokenEndpointPath = new PathString("/token"),
                Provider = new OAuthAuthorizationServerProvider()
                {
                    OnValidateClientAuthentication = async (context) =>
                    {
                        context.Validated();
                    },
                    OnGrantResourceOwnerCredentials = async (context) =>
                    {
                        if (context.UserName == "[email protected]" && context.Password == "test123")
                        {
                            ClaimsIdentity oAuthIdentity = new ClaimsIdentity(context.Options.AuthenticationType);
                            context.Validated(oAuthIdentity);
                        }
                    }
                },
                AllowInsecureHttp = true,
                AccessTokenExpireTimeSpan = TimeSpan.FromDays(1)
            };

            app.UseOAuthBearerTokens(OAuthOptions);
        }
    }
}

Run your project. The token should be displayed in the pop-up.

C++ 11 added initialization lists to allow the following syntax:

std::vector<std::string> v = {"Hello", "World"};

Support for this C++ 11 feature was added in at least GCC 4.4 and only in Visual Studio 2013.

In my view the most realistic scenario is when tasks have a heavy operation to complete. Shivprasad's approach focuses more on object creation/memory allocation than on computing itself. I made a research calling the following method:

public static double SumRootN(int root)
{
    double result = 0;
    for (int i = 1; i < 10000000; i++)
        {
            result += Math.Exp(Math.Log(i) / root);
        }
        return result; 
}

Execution of this method takes about 0.5sec.

I called it 200 times using Parallel:

Parallel.For(0, 200, (int i) =>
{
    SumRootN(10);
});

Then I called it 200 times using the old-fashioned way:

List<Task> tasks = new List<Task>() ;
for (int i = 0; i < loopCounter; i++)
{
    Task t = new Task(() => SumRootN(10));
    t.Start();
    tasks.Add(t);
}

Task.WaitAll(tasks.ToArray()); 

First case completed in 26656ms, the second in 24478ms. I repeated it many times. Everytime the second approach is marginaly faster.

When I used the code mysqld_safe --skip-grant-tables & but I get the error:

mysqld_safe Directory '/var/run/mysqld' for UNIX socket file don't exists.

$ systemctl stop  mysql.service
$ ps -eaf|grep mysql
$ mysqld_safe --skip-grant-tables &

I solved:

$ mkdir -p /var/run/mysqld
$ chown mysql:mysql /var/run/mysqld

Now I use the same code mysqld_safe --skip-grant-tables & and get

mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql

If I use $ mysql -u root I'll get :

Now time to change password:

mysql> use mysql
mysql> describe user;

Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A

Database changed

mysql> FLUSH PRIVILEGES;
mysql> SET PASSWORD FOR root@'localhost' = PASSWORD('newpwd');

or If you have a mysql root account that can connect from everywhere, you should also do:

UPDATE mysql.user SET Password=PASSWORD('newpwd') WHERE User='root';

Alternate Method:

   USE mysql
   UPDATE user SET Password = PASSWORD('newpwd')
   WHERE Host = 'localhost' AND User = 'root';

And if you have a root account that can access from everywhere:

 USE mysql
 UPDATE user SET Password = PASSWORD('newpwd')
 WHERE Host = '%' AND User = 'root';`enter code here

now need to quit from mysql and stop/start

FLUSH PRIVILEGES;
sudo /etc/init.d/mysql stop
sudo /etc/init.d/mysql start

now again ` mysql -u root -p' and use the new password to get

mysql>

Just put DROP TABLE IF EXISTS `tablename`; before your CREATE TABLE statement.

That statement drops the table if it exists but will not throw an error if it does not.

The reason csv doesn't support that is because variable-length lines are not really supported on most filesystems. What you should do instead is collect all the data in lists, then call zip() on them to transpose them after.

>>> l = [('Result_1', 'Result_2', 'Result_3', 'Result_4'), (1, 2, 3, 4), (5, 6, 7, 8)]
>>> zip(*l)
[('Result_1', 1, 5), ('Result_2', 2, 6), ('Result_3', 3, 7), ('Result_4', 4, 8)]

You can also do

subset(df, aged <= laclen)

use

 $(document).height()

  overflow=auto 

for scrolling

Add the following code on build.gragle (project) for adding Google maven repository

allprojects {
    repositories {
    ...
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    ...
    }
}

Just change home to your liking

$home_url = 'http://' . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']) . '/home';

header('Location: ' . $home_url);

To link the entire row, you need to define onclick function on your row, which is <tr>element and define a mouse hover in the CSS for tr element to make the mouse pointer to a typical click-hand in web:

In table:

<tr onclick="location.href='http://www.google.com'">
<td>blah</td>
<td>blah</td>
<td><strong>Text</strong></td>
</tr>

In related CSS:

tr:hover {
cursor: pointer;
}

Note, the localhost is a special string that FB allows here. If you didn't configure your debugging environment under localhost, you'll have to push it underneath that name as far as I can tell.

If you want to do this without VBA, you can use a combination of IF, ISERROR, and MATCH.

So if all values are in column A, enter this formula in column B:

=IF(ISERROR(MATCH(12345,A:A,0)),"Not Found","Value found on row " & MATCH(12345,A:A,0))

This will look for the value "12345" (which can also be a cell reference). If the value isn't found, MATCH returns "#N/A" and ISERROR tries to catch that.

If you want to use VBA, the quickest way is to use a FOR loop:

Sub FindMatchingValue()
    Dim i as Integer, intValueToFind as integer
    intValueToFind = 12345
    For i = 1 to 500    ' Revise the 500 to include all of your values
        If Cells(i,1).Value = intValueToFind then 
            MsgBox("Found value on row " & i)
            Exit Sub
        End If
    Next i

    ' This MsgBox will only show if the loop completes with no success
    MsgBox("Value not found in the range!")  
End Sub

You can use Worksheet Functions in VBA, but they're picky and sometimes throw nonsensical errors. The FOR loop is pretty foolproof.

On Windows environment, you can execute py file on Python3 shell command line with the following syntax:

exec(open('absolute path to file_name').read())

Below explains how to execute a simple helloworld.py file from python shell command line

File Location: C:/Users/testuser/testfolder/helloworld.py

File Content: print("hello world")

We can execute this file on Python3.7 Shell as below:

>>> import os
>>> abs_path = 'C://Users/testuser/testfolder'
>>> os.chdir(abs_path)
>>> os.getcwd()
'C:\\Users\\testuser\\testfolder'

>>> exec(open("helloworld.py").read())
hello world

>>> exec(open("C:\\Users\\testuser\\testfolder\\helloworld.py").read())
hello world

>>> os.path.abspath("helloworld.py")
'C:\\Users\\testuser\\testfolder\\helloworld.py'
>>> import helloworld
hello world

I'm using Bootstrap 4 (Beta 2). Meanwhile the situations seems to have changed. I had the same problem and found an easy solution. This is my code:

<div class="container-fluid content-row">
    <div class="row">
        <div class="col-sm-12 col-lg-6">
            <div class="card h-100">
                … content card …
            </div>
        </div>
        … all the other cards … 
    </div>
</div>

With "col-sm-12 col-lg-6" I've made the cards responsive. With "card h-100" I've set all cards to the height of their parent column. On my system this works, but I'm not a pro. So, hopefully I helped someone.

Another option that works fine for me is to use ConEmu, see http://conemu.github.io/en/ConEmuArgs.html

"C:\Program Files\ConEmu\ConEmu64.exe" -min -run myfile.bat

The reason your code doesn't work as expected is that it's actually doing something different from what you think it does.

Let's say you have something like the following:

stepOne()
.then(stepTwo, handleErrorOne)
.then(stepThree, handleErrorTwo)
.then(null, handleErrorThree);

To better understand what's happening, let's pretend this is synchronous code with try/catch blocks:

try {
    try {
        try {
            var a = stepOne();
        } catch(e1) {
            a = handleErrorOne(e1);
        }
        var b = stepTwo(a);
    } catch(e2) {
        b = handleErrorTwo(e2);
    }
    var c = stepThree(b);
} catch(e3) {
    c = handleErrorThree(e3);
}

The onRejected handler (the second argument of then) is essentially an error correction mechanism (like a catch block). If an error is thrown in handleErrorOne, it will be caught by the next catch block (catch(e2)), and so on.

This is obviously not what you intended.

Let's say we want the entire resolution chain to fail no matter what goes wrong:

stepOne()
.then(function(a) {
    return stepTwo(a).then(null, handleErrorTwo);
}, handleErrorOne)
.then(function(b) {
    return stepThree(b).then(null, handleErrorThree);
});

Note: We can leave the handleErrorOne where it is, because it will only be invoked if stepOne rejects (it's the first function in the chain, so we know that if the chain is rejected at this point, it can only be because of that function's promise).

The important change is that the error handlers for the other functions are not part of the main promise chain. Instead, each step has its own "sub-chain" with an onRejected that is only called if the step was rejected (but can not be reached by the main chain directly).

The reason this works is that both onFulfilled and onRejected are optional arguments to the then method. If a promise is fulfilled (i.e. resolved) and the next then in the chain doesn't have an onFulfilled handler, the chain will continue until there is one with such a handler.

This means the following two lines are equivalent:

stepOne().then(stepTwo, handleErrorOne)
stepOne().then(null, handleErrorOne).then(stepTwo)

But the following line is not equivalent to the two above:

stepOne().then(stepTwo).then(null, handleErrorOne)

Angular's promise library $q is based on kriskowal's Q library (which has a richer API, but contains everything you can find in $q). Q's API docs on GitHub could prove useful. Q implements the Promises/A+ spec, which goes into detail on how then and the promise resolution behaviour works exactly.

EDIT:

Also keep in mind that if you want to break out of the chain in your error handler, it needs to return a rejected promise or throw an Error (which will be caught and wrapped in a rejected promise automatically). If you don't return a promise, then wraps the return value in a resolve promise for you.

This means that if you don't return anything, you are effectively returning a resolved promise for the value undefined.

enum MyEnum {VALUE_1,VALUE_2}

is (approximately) like saying

class MyEnum {

    public static final MyEnum VALUE_1 = new MyEnum("VALUE_1");
    public static final MyEnum VALUE_2 = new MyEnum("VALUE_2");

    private final name;

    private MyEnum(String name) {
        this.name = name;
    }

    public String name() { return this.name }
}

so I guess the all caps is strictly more correct, but still I use the class name convention since I hate all caps wherever

@echo off & setlocal EnableDelayedExpansion
set Var=finding the length of strings
for /l %%A in (0,1,10000) do if not "%Var%"=="!Var:~0,%%A!" (set /a Length+=1) else (echo !Length! & pause & exit /b)

set the var to whatever you want to find the length of it or change it to set /p var= so that the user inputs it. Putting this here for future reference.

FYI, in newer versions of Windows, there's a new setting where if a program is running in Adminstrator mode, then another program not in administrator mode, cannot send any clicks or other input events to it. Check your source program to which you are trying to send the click (right click -> properties), and see if the 'run as administrator' checkbox is selected.

DateTime.ParseExact(input,"yyyyMMdd HH:mm",null);

assuming you meant to say that minutes followed the hours, not seconds - your example is a little confusing.

The ParseExact documentation details other overloads, in case you want to have the parse automatically convert to Universal Time or something like that.

As @Joel Coehoorn mentions, there's also the option of using TryParseExact, which will return a Boolean value indicating success or failure of the operation - I'm still on .Net 1.1, so I often forget this one.

If you need to parse other formats, you can check out the Standard DateTime Format Strings.

if you wanna keep OOP form without turning any error off, you can also:

class A
{
    public function foo() {
        ;
    }
}
class B extends A
{
    /*instead of : 
    public function foo($a, $b, $c) {*/
    public function foo() {
        list($a, $b, $c) = func_get_args();
        // ...

    }
}

You can do something like this:

<input onfocus="(this.type='date')" class="js-form-control" placeholder="Enter Date">

Access-Engine does not support

SELECT count(DISTINCT....) FROM ...

You have to do it like this:

SELECT count(*) 
FROM
(SELECT DISTINCT Name FROM table1)

Its a little workaround... you're counting a DISTINCT selection.

From the above answeres, following did not work or less preferable:

• (previous_info | json) != '{}' works only for {} empty case, not for null or undefined case
• Object.getOwnPropertyNames(previous_info).length also did not work, as Object is not accessible in the template
• I would not like to create a dedicated variable this.objectLength = Object.keys(this.previous_info).length !=0;

• I would not like to create a dedicated function

  isEmptyObject(obj) {
     return (obj && (Object.keys(obj).length === 0));
  }
  

Solution: keyvalue pipe along with ?. (safe navigation operator); and it seems simple.

It works well when previous_info = null or previous_info = undefined or previous_info = {} and treats as falsy value.

<div  *ngIf="(previous_info | keyvalue)?.length">

keyvalue - Transforms Object or Map into an array of key value pairs.

?. - The Angular safe navigation operator (?.) is a fluent and convenient way to guard against null and undefined

DEMO: demo with angular 9, though it works for previous versions as well

I realize this question is fairly old, but wanted to share a quick demo of group transforms, paths/shapes, and relative positioning, for anyone else who found their way here looking for more info:

Using JODA:

PeriodFormatter periodFormat = new PeriodFormatterBuilder()
  .minimumParsedDigits(2)
  .appendHour() // 2 digits minimum
  .appendSeparator(":")
  .minimumParsedDigits(2)
  .appendMinute() // 2 digits minimum
  .appendSeparator(":")
  .minimumParsedDigits(2)
  .appendSecond()
  .appendSeparator(".")
  .appendMillis3Digit()
  .toFormatter();
Period result = Period.parse(string, periodFormat);
return result.toStandardDuration().getMillis();

there is no standard, but most frameworks support both, you can see for example for java spring that it accepts both here

@GetMapping("/api/foos")
@ResponseBody
public String getFoos(@RequestParam List<String> id) {
    return "IDs are " + id;
}

And Spring MVC will map a comma-delimited id parameter:

http://localhost:8080/api/foos?id=1,2,3
----
IDs are [1,2,3]

Or a list of separate id parameters:

http://localhost:8080/api/foos?id=1&id=2
----
IDs are [1,2]

And also

library(dplyr)
data %>% filter(!v1 %in% c("b", "d", "e"))

or

data %>% filter(v1 != "b" & v1 != "d" & v1 != "e")

or

data %>% filter(v1 != "b", v1 != "d", v1 != "e")

Since the & operator is implied by the comma.

A control that is missing from the original set of WPF controls, but much used, is the NumericUpDown control. It is a neat way to get users to select a number from a fixed range, in a small area. A slider could be used, but for compact forms with little horizontal real-estate, the NumericUpDown is essential.

Solution A (via WindowsFormsHost)

You can use the Windows Forms NumericUpDown control in WPF by hosting it in a WindowsFormsHost. Pay attention that you have to include a reference to System.Windows.Forms.dll assembly.

<Window x:Class="WpfApplication61.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:wf="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms" 
        Title="MainWindow" Height="350" Width="525">
    <StackPanel>    
        <WindowsFormsHost>
            <wf:NumericUpDown/>
        </WindowsFormsHost>
...

Solution B (custom)

There are several commercial and codeplex versions around, but both involve installing 3rd party dlls and overheads to your project. Far simpler to build your own, and a aimple way to do that is with the ScrollBar.

A vertical ScrollBar with no Thumb (just the repeater buttons) is in fact just what we want. It inherits rom RangeBase, so it has all the properties we need, like Min, Max, and SmallChange (set to 1, to restrict it to Integer values)

So we change the ScrollBar ControlTemplate. First we remove the Thumb and Horizontal trigger actions. Then we group the remains into a grid and add a TextBlock for the number:

<Grid Margin="2">
    <Grid.ColumnDefinitions>
        <ColumnDefinition/>
        <ColumnDefinition />
    </Grid.ColumnDefinitions>
    <TextBlock VerticalAlignment="Center" FontSize="20" MinWidth="25" Text="{Binding Value, RelativeSource={RelativeSource TemplatedParent}}"/>
    <Grid Grid.Column="1" x:Name="GridRoot" Width="{DynamicResource {x:Static SystemParameters.VerticalScrollBarWidthKey}}" Background="{TemplateBinding Background}">
        <Grid.RowDefinitions>
            <RowDefinition MaxHeight="18"/>
            <RowDefinition Height="0.00001*"/>
            <RowDefinition MaxHeight="18"/>
        </Grid.RowDefinitions>
        <RepeatButton x:Name="DecreaseRepeat" Command="ScrollBar.LineDownCommand" Focusable="False">
            <Grid>
                <Path x:Name="DecreaseArrow" Stroke="{TemplateBinding Foreground}" StrokeThickness="1" Data="M 0 4 L 8 4 L 4 0 Z"/>
            </Grid>
        </RepeatButton>
        <RepeatButton Grid.Row="2" x:Name="IncreaseRepeat" Command="ScrollBar.LineUpCommand" Focusable="False">
            <Grid>
                <Path x:Name="IncreaseArrow" Stroke="{TemplateBinding Foreground}" StrokeThickness="1" Data="M 0 0 L 4 4 L 8 0 Z"/>
            </Grid>
        </RepeatButton>
    </Grid>
</Grid>

System.exit() terminates the JVM. Nothing after System.exit() is executed. Return is generally used for exiting a method. If the return type is void, then you could use return; But I don't think is a good practice to do it in the main method. You don't have to do anything for terminate a program, unless infinite loop or some strange other execution flows.

In my case, after the recent (Mac OS High Sierra) upgrade and the subsequent brew upgrade, I started to see the above error. I followed the above instructions but still got the same error message. Then I realised that I had to use python2 which points to the brew installed python rather than the os x installed one.

AsynchonousRequest

let urlString = "http://heyhttp.org/me.json"
var request = URLRequest(url: URL(string: urlString)!)
let session = URLSession.shared

session.dataTask(with: request) {data, response, error in
  if error != nil {
    print(error!.localizedDescription)
    return

  do {
    let jsonResult: NSDictionary? = try JSONSerialization.jsonObject(with: data!, options: JSONSerialization.ReadingOptions.mutableContainers) as? NSDictionary
    print("Synchronous\(jsonResult)")

After following the steps from @Johnride, I still got the same error.

If you look in the source code for $.fn.bind you will find that it's just an rewrite function for on:

Note: To avoid conflicts between parallel Python 2 and Python 3 installations, only the versioned pip3 and pip3.4 commands are bootstrapped by default when ensurepip is invoked directly - the --default-pip option is needed to also request the unversioned pip command. pyvenv and the Windows installer ensure that the unqualified pip command is made available in those environments, and pip can always be invoked via the -m switch rather than directly to avoid ambiguity on systems with multiple Python installations.

So try pip3 or pip3.4 in Command Prompt.

Also, ensure that environment variable are set for pip command, if you missed to opt-in for automatic PATH configuration.

Thought of writing this answer as nothing worked from above & you don't want to specify proxy location.

If you're using httpClient then consider this.

HttpClientHandler handler = new HttpClientHandler();

IWebProxy proxy = WebRequest.GetSystemWebProxy();
proxy.Credentials = CredentialCache.DefaultCredentials;
handler.Proxy = proxy;

var client = new HttpClient(handler);
// your next steps...

And if you're using HttpWebRequest:

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri + _endpoint);

IWebProxy proxy = WebRequest.GetSystemWebProxy();
proxy.Credentials = CredentialCache.DefaultCredentials;
request.Proxy = proxy;

It means, when an error happens on the line, it is telling vbscript to continue execution without aborting the script. Sometimes, the On Error follows the Goto label to alter the flow of execution, something like this in a Sub code block, now you know why and how the usage of GOTO can result in spaghetti code:

Sub MySubRoutine()
   On Error Goto ErrorHandler

   REM VB code...

   REM More VB Code...

Exit_MySubRoutine:

   REM Disable the Error Handler!

   On Error Goto 0

   REM Leave....
   Exit Sub

ErrorHandler:

   REM Do something about the Error

   Goto Exit_MySubRoutine
End Sub

Another way to do this solely with css:

input[type='checkbox'] {
  float: left;
  width: 20px;
}
input[type='checkbox'] + label {
  display: block;
  width: 30px;
}

Note that this forces each checkbox and its label onto a separate line, rather than only doing so only when there's overflow.

Chrome will make requests with CORS from a localhost origin just fine. This isn't a problem with Chrome.

The reason you can't load http://stackoverflow.com is that the Access-Control-Allow-Origin headers weren't allowing your localhost origin.

Solution for me (Android Studio) :

1) Use shortcut Ctrl+Shift+Alt+S or File -> Project Structure

2) and increase the level of SDK "Compile SDK Version".

Solved! The call build job: project, parameters: params fails with an error java.lang.UnsupportedOperationException: must specify $class with an implementation of interface java.util.List when params = [:]. Replacing it with params = null solved the issue. Here the working code below.

def doCopyMibArtefactsHere(projectName) {
    step ([
        $class: 'CopyArtifact',
        projectName: projectName,
        filter: '**/**.mib',
        fingerprintArtifacts: true, 
        flatten: true
    ]);
}

def BuildAndCopyMibsHere(projectName, params = null) {
    build job: project, parameters: params
    doCopyMibArtefactsHere(projectName)
}
node { 
    stage('Prepare Mib'){
        BuildAndCopyMibsHere('project1')
    }
}

Pass data changeFormate(15/07/2020)

let incomingDateChnge: any = new Date(date);
let incomingDay = incomingDateChnge.getDate();
let incomingMonth = incomingDateChnge.getMonth();

let incomingYear = incomingDateChnge.getFullYear();

Simply use the base transpose function t, wrapped with as.data.frame:

final_df <- as.data.frame(t(starting_df))
final_df
     A    B    C    D
a    1    2    3    4
b 0.02 0.04 0.06 0.08
c Aaaa Bbbb Cccc Dddd

Above updated. As docendo discimus pointed out, t returns a matrix. As Mark suggested wrapping it with as.data.frame gets back a data frame instead of a matrix. Thanks!

You should look this example to understand Lazy Loading architecture

private readonly Lazy<List<int>> list = new Lazy<List<int>>(() =>
{
    List<int> configList = new List<int>(Thread.CurrentThread.ManagedThreadId);
    return configList;
});
public void Execute()
{
    list.Value.Add(0);
    if (list.IsValueCreated)
    {
        list.Value.Add(1);
        list.Value.Add(2);

        foreach (var item in list.Value)
        {
            Console.WriteLine(item);
        }
    }
    else
    {
        Console.WriteLine("Value not created");
    }
}

--> output --> 0 1 2

but if this code dont write "list.Value.Add(0);"

output --> Value not created

I think what you want is this:

ASP.NET MVC1

Html.ActionLink(article.Title, 
                "Login",  // <-- Controller Name.
                "Item",   // <-- ActionMethod
                new { id = article.ArticleID }, // <-- Route arguments.
                null  // <-- htmlArguments .. which are none. You need this value
                      //     otherwise you call the WRONG method ...
                      //     (refer to comments, below).
                )

This uses the following method ActionLink signature:

public static string ActionLink(this HtmlHelper htmlHelper, 
                                string linkText,
                                string controllerName,
                                string actionName,
                                object values, 
                                object htmlAttributes)

ASP.NET MVC2

two arguments have been switched around

Html.ActionLink(article.Title, 
                "Item",   // <-- ActionMethod
                "Login",  // <-- Controller Name.
                new { id = article.ArticleID }, // <-- Route arguments.
                null  // <-- htmlArguments .. which are none. You need this value
                      //     otherwise you call the WRONG method ...
                      //     (refer to comments, below).
                )

This uses the following method ActionLink signature:

public static string ActionLink(this HtmlHelper htmlHelper, 
                                string linkText,
                                string actionName,
                                string controllerName,
                                object values, 
                                object htmlAttributes)

ASP.NET MVC3+

arguments are in the same order as MVC2, however the id value is no longer required:

Html.ActionLink(article.Title, 
                "Item",   // <-- ActionMethod
                "Login",  // <-- Controller Name.
                new { article.ArticleID }, // <-- Route arguments.
                null  // <-- htmlArguments .. which are none. You need this value
                      //     otherwise you call the WRONG method ...
                      //     (refer to comments, below).
                )

This avoids hard-coding any routing logic into the link.

 <a href="/Item/Login/5">Title</a> 

This will give you the following html output, assuming:

1. article.Title = "Title"
2. article.ArticleID = 5
3. you still have the following route defined

. .

routes.MapRoute(
    "Default",     // Route name
    "{controller}/{action}/{id}",                           // URL with parameters
    new { controller = "Home", action = "Index", id = "" }  // Parameter defaults
);

I spent over 3 hours to find out solution. Actually port 80 was being used by "system" service so I tried to change port from 80 to 8080 in "httpd" file but same problem raised "port 80 is used by system". It had driven me mad for 3 hours as every thing was changed like port , localhost server etc pointing to 8080.

At last I found mistake that was server root. Basically "Server Root" in "httpd" should be pointing to apache foler of xampp. In my case that's was

ServerRoot "xampp/apache"

I just changed it as follows:

ServerRoot "C:/xampp/apache" 

It has worked successfully and now everything is running with OK status.

FWIW: I was getting "Android.Views.InflateException Message=Binary XML file line #1: Binary XML file line #1: Error inflating class android.view.TextureView"

I am new to android form design. In trying to put a border on some buttons I found an SO post that inspired me to create buttonborder.xml that looks like:

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
<solid android:color="@android:color/transparent" />
<stroke android:width="1dp" android:color="@android:color/white"/>

Then for each button I added

android:background="@drawable/buttonborder"

However, in my enthusiasm I also added it to a TextureView - which was my problem. When I removed the line from the TextureView, things worked.

Your question is already answered here :

• Why do we use rt.jar file in java project ?

Basically, rt.jar contains all of the compiled class files for the base Java Runtime ("rt") Environment. Normally, javac should know the path to this file

Also, a good link on what happens if we try to include our class file in rt.jar.

I did the following:

var defaultOption = new Option();
defaultOption.selected = true;    
$(".js-select2").append(defaultOption);

For other options I use then:

var realOption = new Option("Option Value", "id");
realOption.selected = false;    
$(".js-select2").append(realOption);

I ran into this issue as well and found this post. Ultimately none of these answers solved my problem, instead I had to put in a rewrite rule to strip out the location /rt as the backend my developers made was not expecting any additional paths:

+-(william@wkstn18)--(Thu, 05 Nov 20)-+
+-(~)--(16:13)->wscat -c ws://WebsocketServerHostname/rt
error: Unexpected server response: 502

Testing with wscat repeatedly gave a 502 response. Nginx error logs provided the same upstream error as above, but notice the upstream string shows the GET Request is attempting to access localhost:12775/rt and not localhost:12775:

 2020/11/05 22:13:32 [error] 10175#10175: *7 upstream prematurely closed
 connection while reading response header from upstream, client: WANIP,
 server: WebsocketServerHostname, request: "GET /rt/socket.io/?transport=websocket
 HTTP/1.1", upstream: "http://127.0.0.1:12775/rt/socket.io/?transport=websocket",
 host: "WebsocketServerHostname"

Since the devs had not coded their websocket (listening on 12775) to expect /rt/socket.io but instead just /socket.io/ (NOTE: /socket.io/ appears to just be a way to specify websocket transport discussed here). Because of this, rather than ask them to rewrite their socket code I just put in a rewrite rule to translate WebsocketServerHostname/rt to WebsocketServerHostname:12775 as below:

upstream websocket-rt {
        ip_hash;

        server 127.0.0.1:12775;
}

server {
        listen 80;
        server_name     WebsocketServerHostname;

        location /rt {
                proxy_http_version 1.1;

                #rewrite /rt/ out of all requests and proxy_pass to 12775
                rewrite /rt/(.*) /$1  break;

There is are multiple ways to execute the commands or script in the multiple remote Linux machines. One simple & easiest way is via pssh (parallel ssh program)

pssh: is a program for executing ssh in parallel on a number of hosts. It provides features such as sending input to all of the processes, passing a password to ssh, saving the output to files, and timing out.

Example & Usage:

Connect to host1 and host2, and print "hello, world" from each:

 pssh -i -H "host1 host2" echo "hello, world"

Run commands via a script on multiple servers:

pssh -h hosts.txt -P -I<./commands.sh

Usage & run a command without checking or saving host keys:

pssh -h hostname_ip.txt -x '-q -o StrictHostKeyChecking=no -o PreferredAuthentications=publickey -o PubkeyAuthentication=yes' -i  'uptime; hostname -f'

If the file hosts.txt has a large number of entries, say 100, then the parallelism option may also be set to 100 to ensure that the commands are run concurrently:

pssh -i -h hosts.txt -p 100 -t 0 sleep 10000

Options:
-I: Read input and sends to each ssh process.
-P: Tells pssh to display output as it arrives.
-h: Reads the host's file.
-H : [user@]host[:port] for single-host.
-i: Display standard output and standard error as each host completes
-x args: Passes extra SSH command-line arguments
-o option: Can be used to give options in the format used in the configuration file.(/etc/ssh/ssh_config) (~/.ssh/config)
-p parallelism: Use the given number as the maximum number of concurrent connections
-q Quiet mode: Causes most warning and diagnostic messages to be suppressed.
-t: Make connections time out after the given number of seconds. 0 means pssh will not timeout any connections

When ssh'ing to the remote machine, how to handle when it prompts for RSA fingerprint authentication.

Disable the StrictHostKeyChecking to handle the RSA authentication prompt.
-o StrictHostKeyChecking=no

Under Windows 7 I had anaconda and anaconda3 installed. I went into \Users\me\anaconda\Scripts and executed

sudo .\ipython kernelspec install-self

then I went into \Users\me\anaconda3\Scripts and executed

sudo .\ipython kernel install

(I got jupyter kernelspec install-self is DEPRECATED as of 4.0. You probably want 'ipython kernel install' to install the IPython kernelspec.)

After starting jupyter notebook (in anaconda3) I got a neat dropdown menu in the upper right corner under "New" letting me choose between Python 2 odr Python 3 kernels.

if you are want session timeout for website than remove

<authentication mode="Forms">
      <forms timeout="50"/>
</authentication>

tag from web.config file.

For completeness - adding to accepted answer above - in case you are interested in any sibling regardless of the element type you can use variation:

I upgraded to Windows 10 x64 (from Windows 7 x64), had a VirtualBox Windows 10 x64 VM, but got the VT-x error. My BIOS was enabled, settings - everything in this post was addressed, but still got the VT-x error.

What fixed it for me was to go to Lenovo and install the latest BIOS for my W550s ThinkPad. Once the upgrade was installed, VirtualBox gave me the x64 options again with no more VT-x errors.

If you are running a W550s, the BIOS version I installed was from September 2015, "BIOS Update Utility" n11uj05w.exe, version 1.10 from the Lenovo website.

It just associates a semaphore with every object, and uses that.

u can make

'xxxx' text u search and will replace it with 'yyyy'

grep -Rn '**xxxx**' /path | awk -F: '{print $1}' | xargs sed -i 's/**xxxx**/**yyyy**/'

When your function is deterministic, you are safe to declare it to be deterministic. The location of "DETERMINISTIC" keyword is as follows.

Sending data from Activity to a Fragment

Activity:

Bundle bundle = new Bundle();
String myMessage = "Stackoverflow is cool!";
bundle.putString("message", myMessage );
FragmentClass fragInfo = new FragmentClass();
fragInfo.setArguments(bundle);
transaction.replace(R.id.fragment_single, fragInfo);
transaction.commit();

Fragment:

Reading the value in fragment

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    String myValue = this.getArguments().getString("message");
    ...
    ...
    ...
}

But if you want to send values from Fragment to Activity, read the answer of jpardogo, you must need interfaces, more info: Communicating with other Fragments

I could not get IE8+ to work by adding a jQuery event handler to the file input type. I had to go old-school and add the the onchange="" attribute to the input tag:

<input type='file' onchange='getFilename(this)'/>

function getFileName(elm) {
   var fn = $(elm).val();
   ....
}

EDIT:

function getFileName(elm) {
   var fn = $(elm).val();
   var filename = fn.match(/[^\\/]*$/)[0]; // remove C:\fakename
   alert(filename);
}

The most reliable and technically correct approach is to transform the data in the controller. Here's a simple chunk function and usage.

function chunk(arr, size) {
  var newArr = [];
  for (var i=0; i<arr.length; i+=size) {
    newArr.push(arr.slice(i, i+size));
  }
  return newArr;
}

$scope.chunkedData = chunk(myData, 3);

Then your view would look like this:

<div class="row" ng-repeat="rows in chunkedData">
  <div class="span4" ng-repeat="item in rows">{{item}}</div>
</div>

If you have any inputs within the ng-repeat, you will probably want to unchunk/rejoin the arrays as the data is modified or on submission. Here's how this would look in a $watch, so that the data is always available in the original, merged format:

$scope.$watch('chunkedData', function(val) {
  $scope.data = [].concat.apply([], val);
}, true); // deep watch

Many people prefer to accomplish this in the view with a filter. This is possible, but should only be used for display purposes! If you add inputs within this filtered view, it will cause problems that can be solved, but are not pretty or reliable.

The problem with this filter is that it returns new nested arrays each time. Angular is watching the return value from the filter. The first time the filter runs, Angular knows the value, then runs it again to ensure it is done changing. If both values are the same, the cycle is ended. If not, the filter will fire again and again until they are the same, or Angular realizes an infinite digest loop is occurring and shuts down. Because new nested arrays/objects were not previously tracked by Angular, it always sees the return value as different from the previous. To fix these "unstable" filters, you must wrap the filter in a memoize function. lodash has a memoize function and the latest version of lodash also includes a chunk function, so we can create this filter very simply using npm modules and compiling the script with browserify or webpack.

Remember: display only! Filter in the controller if you're using inputs!

Install lodash:

npm install lodash-node

Create the filter:

var chunk = require('lodash-node/modern/array/chunk');
var memoize = require('lodash-node/modern/function/memoize');

angular.module('myModule', [])
.filter('chunk', function() {
  return memoize(chunk);
});

And here's a sample with this filter:

<div ng-repeat="row in ['a','b','c','d','e','f'] | chunk:3">
  <div class="column" ng-repeat="item in row">
    {{($parent.$index*row.length)+$index+1}}. {{item}}
  </div>
</div>

Order items vertically

1  4
2  5
3  6

Regarding vertical columns (list top to bottom) rather than horizontal (left to right), the exact implementation depends on the desired semantics. Lists that divide up unevenly can be distributed different ways. Here's one way:

<div ng-repeat="row in columns">
  <div class="column" ng-repeat="item in row">
    {{item}}
  </div>
</div>

var data = ['a','b','c','d','e','f','g'];
$scope.columns = columnize(data, 3);
function columnize(input, cols) {
  var arr = [];
  for(i = 0; i < input.length; i++) {
    var colIdx = i % cols;
    arr[colIdx] = arr[colIdx] || [];
    arr[colIdx].push(input[i]);
  }
  return arr;
}

However, the most direct and just plainly simple way to get columns is to use CSS columns:

.columns {
  columns: 3;
}

<div class="columns">
  <div ng-repeat="item in ['a','b','c','d','e','f','g']">
    {{item}}
  </div>
</div>

alternatively you can put onchange attribute on the dropdownlist itself, that onchange will call certain jquery function like this.

<input type="dropdownlist" onchange="jqueryFunc()">

<script type="text/javascript">
$(function(){
    jqueryFunc(){
        //something goes here
    }
});
</script>

hope this one helps you, and please note that this code is just a rough draft, not tested on any ide. thanks

Please add these 2 simple line of code:

self.YourViewName.layer.cornerRadius = 15
self.YourViewName.layer.masksToBounds = true

It will work fine.

Here buddy. This function will match your date with any specific date and will be able to tell whether they match or not. You can also modify the components to match your requirements.

- (BOOL)isSameDay:(NSDate*)date1 otherDay:(NSDate*)date2 {
NSCalendar* calendar = [NSCalendar currentCalendar];

unsigned unitFlags = NSYearCalendarUnit | NSMonthCalendarUnit |  NSDayCalendarUnit;
NSDateComponents* comp1 = [calendar components:unitFlags fromDate:date1];
NSDateComponents* comp2 = [calendar components:unitFlags fromDate:date2];

return [comp1 day]   == [comp2 day] &&
[comp1 month] == [comp2 month] &&
[comp1 year]  == [comp2 year];}

Please try this out to take into account all possible scenarios:

awk '{print $(NF-1)"\t"$NF}'  file

or

awk 'BEGIN{OFS="\t"}' file

or

awk '{print $(NF-1), $NF} {print $(NF-1), $NF}' file

To start the batch file at the start of your system, you can also use a registry key.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

Here you can create a string. As name you can choose anything and the data is the full path to your file.

There is also the registry key

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce

to run something at only the next start of your system.

There is actually a way to have a shell in the container.

Assume your /root/run.sh launches the process, process manager (supervisor), or whatever.

Create /root/runme.sh with some gnu-screen tricks:

# Spawn a screen with two tabs
screen -AdmS 'main' /root/run.sh
screen -S 'main' -X screen bash -l
screen -r 'main'

Now, you have your daemons in tab 0, and an interactive shell in tab 1. docker attach at any time to see what's happening inside the container.

Another advice is to create a "development bundle" image on top of the production image with all the necessary tools, including this screen trick.

PyInstaller will create a single-file executable if you use the --onefile option (though what it actually does is extracts then runs itself).

There's a simple PyInstaller tutorial here. If you have any questions about using it, please post them...

You can use this in a header file.

// setup session enviroment
ini_set('session.cookie_httponly',1);
ini_set('session.use_only_cookies',1);

This way all future session cookies will use httponly.

do not zip any hidden file:

zip newzipname filename.any  -x "\.*"

with this question, it should be like:

zip newzipname filename.any  -x "\__MACOSX"

It must be said, though, zip command runs in terminal just compressing the file, it does not compress any others. So do this the result is the same:

zip newzipname filename.any

Simple way to initiate the message on startup:

bot.on('ready', () => {
    bot.user.setStatus('available')
    bot.user.setPresence({
        game: {
            name: 'with depression',
            type: "STREAMING",
            url: "https://www.twitch.tv/monstercat"
        }
    });
});

You can also just declare it elsewhere after startup, to change the message as needed:

bot.user.setPresence({ game: { name: 'with depression', type: "streaming", url: "https://www.twitch.tv/monstercat"}}); 

It looks like github has a simple UI for creating branches. I opened the branch drop-down and it prompts me to "Find or create a branch ...". Type the name of your new branch, then click the "create" button that appears.

To retrieve your new branch from github, use the standard git fetch command.

I'm not sure this will help your underlying problem, though, since the underlying data being pushed to the server (the commit objects) is the same no matter what branch it's being pushed to.

Brief summary of Microsoft gadget development:

What are they written in? Windows Vista/Seven gadgets are developed in a mix of XML, HTML, CSS, and some IE scripting language. It is also possible to use C# with the latest release of Script#.

How are they packaged/deployed? The actual gadgets are stored in *.gadget files, which are simply the text source files listed above compressed into a single zip file.

Useful references for gadget development:

where do I start? Good introductory references to Windows Vista/Seven gadget development:

• Developing Gadgets for the Windows Sidebar
• Vista Gadgets Introductory tutorial from I-Programmer
• Authoring Sidebar Gadgets in C#
• Developing a Gadget for Windows Sidebar Part 1: The Basics Official MSDN tutorial.

If you are willing to use offline resources, this book appears to be an excellent resource:

• Creating Vista Gadgets: Using HTML, CSS and JavaScript with Examples in RSS, Ajax, ActiveX (COM) and Silverlight
• blog related to book: http://www.innovatewithgadgets.com/

What do I need to know? Some other useful references; not necessarily instructional

Update: Well, this has proven to be a popular answer~ Sharing my own recent experience with Windows 7 gadget development:

Perhaps the easiest way to get started with Windows 7 gadget development is to modify a gadget that has already been developed. I recently did this myself because I wanted a larger clock gadget. Unable to find any, I tinkered with a copy of the standard Windows clock gadget until it was twice as large. I recommend starting with the clock gadget because it is fairly small and well-written. Here is the process I used:

1. Locate the gadget you wish to modify. They are located in several different places. Search for folders named *.gadget. Example: C:\Program Files\Windows Sidebar\Gadgets\Clock.Gadget\
2. Make a copy of this folder (installed gadgets are not wrapped in zip files.)
3. Rename some key parts:
   1. The folder name
   2. The name inside the gadget.xml file. It looks like:<name>Clock</name> This is the name that will be displayed in the "Gadgets Gallery" window.
4. Zip up the entire *.gadget directory.
5. Change the file extension from "zip" to "gadget" (Probably just need to remove the ".zip" extension.)
6. Install your new copy of the gadget by double clicking the new *.gadget file. You can now add your gadget like any other gadget (right click desktop->Gadgets)
7. Locate where this gadget is installed (probably to %LOCALAPPDATA%\Microsoft\Windows Sidebar\)
8. Modify the files in this directory. The gadget is very similar to a web page: HTML, CSS, JS, and image files. The gadget.xml file specifies which file is opened as the "index" page for the gadget.
9. After you save the changes, view the results by installing a new instance of the gadget. You can also debug the JavaScript (The rest of that article is pretty informative, too).

Figure sizes are specified in inches and can be included as a global option of the document output format. For example:

---
title: "My Document"
output:
  html_document:
    fig_width: 6
    fig_height: 4
---

And the plot's size in the graphic device can be increased at the chunk level:

```{r, fig.width=14, fig.height=12}          #Expand the plot width to 14 inches

ggplot(aes(x=mycolumn1, y=mycolumn2)) +     #specify the x and y aesthetic
geom_line(size=2) +                         #makes the line thicker
theme_grey(base_size = 25)                  #increases the size of the font
```

You can also use the out.width and out.height arguments to directly define the size of the plot in the output file:

```{r, out.width="200px", out.height="200px"} #Expand the plot width to 200 pixels

ggplot(aes(x=mycolumn1, y=mycolumn2)) +     #specify the x and y aesthetic
geom_line(size=2) +                         #makes the line thicker
theme_grey(base_size = 25)                  #increases the size of the font
```

A single way to remove sessions is setting it to null;

Session["your_session"] = null;

The answer with

<div 
    className="player"
    onKeyDown={this.onKeyPressed}
    tabIndex={0}
>

works for me, please note that the tabIndex requires a number, not a string, so tabIndex="0" doesn't work.

The @see tag is a bit different than the @link tag,
limited in some ways and more flexible in others:

^{Different JavaDoc link types}

1. Displays the member name for better learning, and is refactorable; the name will update when renaming by refactor
2. Refactorable and customizable; your text is displayed instead of the member name
3. Displays name, refactorable
4. Refactorable, customizable
5. A rather mediocre combination that is:

• Refactorable, customizable, and stays in the See Also section
• Displays nicely in the Eclipse hover
• Displays the link tag and its formatting when generated
• When using multiple @see items, commas in the description make the output confusing

6. Completely illegal; causes unexpected content and illegal character errors in the generator

See the results below:

^{JavaDoc generation results with different link types}

Best regards.

You first add css

html,body{
height:100%;
}

This will be the html:

 <div style="position:relative;height:100%;max-width:500px;margin:auto">
    <iframe src="xyz.pdf" frameborder="0" width="100%" height="100%">
    <p>Your browser does not support iframes.</p>
    </iframe>
    </div>

You can do this more easy way. And 100% works that you want

<?php
    $servername = "localhost";
    $username = "root";
    $password = "";  //your database password
    $dbname = "demo";  //your database name

    $con = new mysqli($servername, $username, $password, $dbname);

    if ($con->connect_error) {
        die("Connection failed: " . $con->connect_error);
    }
    else
    {
        //echo ("Connect Successfully");
    }
    $query = "SELECT Date_time, Tempout FROM alarm_value"; // select column
    $aresult = $con->query($query);

?>

What I don't understand is what to do in Df when 'OK' is pressed in order to remove fragments Df, Cf, and Bf?

Step #1: Have Df tell D "yo! we got the OK click!" via calling a method, either on the activity itself, or on an interface instance supplied by the activity.

Step #2: Have D remove the fragments via FragmentManager.

The hosting activity (D) is the one that knows what other fragments are in the activity (vs. being in other activities). Hence, in-fragment events that might affect the fragment mix should be propagated to the activity, which will make the appropriate orchestration moves.

instead of using the brackets use the object operator for example my array based on database object is created like this in a class called DB:

class DB {
private static $_instance = null;
private $_pdo,
        $_query, 
        $_error = false,
        $_results,
        $_count = 0;



private function __construct() {
    try{
        $this->_pdo = new PDO('mysql:host=' . Config::get('mysql/host') .';dbname=' . Config::get('mysql/db') , Config::get('mysql/username') ,Config::get('mysql/password') );


    } catch(PDOException $e) {
        $this->_error = true;
        $newsMessage = 'Sorry.  Database is off line';
        $pagetitle = 'Teknikal Tim - Database Error';
        $pagedescription = 'Teknikal Tim Database Error page';
        include_once 'dbdown.html.php';
        exit;
    }
    $headerinc = 'header.html.php';
}

public static function getInstance() {
    if(!isset(self::$_instance)) {
        self::$_instance = new DB();
    }

    return self::$_instance;

}


    public function query($sql, $params = array()) {
    $this->_error = false;
    if($this->_query = $this->_pdo->prepare($sql)) {
    $x = 1;
        if(count($params)) {
        foreach($params as $param){
            $this->_query->bindValue($x, $param);
            $x++;
            }
        }
    }
    if($this->_query->execute()) {

        $this->_results = $this->_query->fetchAll(PDO::FETCH_OBJ);
        $this->_count = $this->_query->rowCount();

    }

    else{
        $this->_error = true;
    }

    return $this;
}

public function action($action, $table, $where = array()) {
    if(count($where) ===3) {
        $operators = array('=', '>', '<', '>=', '<=');

        $field      = $where[0];
        $operator   = $where[1];
        $value      = $where[2];

        if(in_array($operator, $operators)) {
            $sql = "{$action} FROM {$table} WHERE {$field} = ?";

            if(!$this->query($sql, array($value))->error()) {
            return $this;
            }
        }

    }
    return false;
}

    public function get($table, $where) {
    return $this->action('SELECT *', $table, $where);

public function results() {
    return $this->_results;
}

public function first() {
    return $this->_results[0];
}

public function count() {
    return $this->_count;
}

}

to access the information I use this code on the controller script:

<?php
$pagetitle = 'Teknikal Tim - Service Call Reservation';
$pagedescription = 'Teknikal Tim Sevice Call Reservation Page';
require_once $_SERVER['DOCUMENT_ROOT'] .'/core/init.php';
$newsMessage = 'temp message';

$servicecallsdb = DB::getInstance()->get('tt_service_calls', array('UserID',
 '=','$_SESSION['UserID']));

if(!$servicecallsdb) {
// $servicecalls[] = array('ID'=>'','ServiceCallDescription'=>'No Service Calls');
} else {
$servicecalls = $servicecallsdb->results();
}
include 'servicecalls.html.php';



?>

then to display the information I check to see if servicecalls has been set and has a count greater than 0 remember it's not an array I am referencing so I access the records with the object operator "->" like this:

<?php include $_SERVER['DOCUMENT_ROOT'] .'/includes/header.html.php';?>
<!--Main content-->
<div id="mainholder"> <!-- div so that page footer can have a minum height from the
  header -->
<h1><?php if(isset($pagetitle)) htmlout($pagetitle);?></h1>
<br>
<br>
<article>
    <h2></h2>
</article>
<?php
if (isset($servicecalls)) {
if (count ($servicecalls) > 0){
     foreach ($servicecalls as $servicecall) {
        echo '<a href="/servicecalls/?servicecall=' .$servicecall->ID .'">'
  .$servicecall->ServiceCallDescription .'</a>';
    }
}else echo 'No service Calls';

}

?>
<a href="/servicecalls/?new=true">Raise New Service Call</a>
</div> <!-- Main content end-->
<?php include $_SERVER['DOCUMENT_ROOT'] .'/includes/footer.html.php'; ?>

Use brackets:

mysql_query("SELECT * FROM Drinks WHERE email='$Email' AND 
    (date='$Date_Today' 
     OR date='$Date_Yesterday' 
     OR date='$Date_TwoDaysAgo' 
     OR date='$Date_ThreeDaysAgo' 
     OR date='$Date_FourDaysAgo' 
     OR date='$Date_FiveDaysAgo' 
     OR date='$Date_SixDaysAgo' 
     OR date='$Date_SevenDaysAgo'
    )
");

But you should alsos have a look at the IN operator. So you can say ´date IN ('$date1','$date2',...)`

But if you have always a set of consecutive days why don't you do the following for the date part

date <= $Date_Today AND date >= $Date_SevenDaysAgo

As mentioned in other answers, all of the following will work for the standard string-based syntax.

WAITFOR DELAY '02:00' --Two hours
WAITFOR DELAY '00:02' --Two minutes
WAITFOR DELAY '00:00:02' --Two seconds
WAITFOR DELAY '00:00:00.200' --Two tenths of a seconds

There is also an alternative method of passing it a DATETIME value. You might think I'm confusing this with WAITFOR TIME, but it also works for WAITFOR DELAY.

Considerations for passing DATETIME:

• It must be passed as a variable, so it isn't a nice one-liner anymore.
• The delay is measured as the time since the Epoch ('1900-01-01').
• For situations that require a variable amount of delay, it is much easier to manipulate a DATETIME than to properly format a VARCHAR.

How to wait for 2 seconds:

--Example 1
DECLARE @Delay1 DATETIME
SELECT @Delay1 = '1900-01-01 00:00:02.000'
WAITFOR DELAY @Delay1

--Example 2
DECLARE @Delay2 DATETIME
SELECT @Delay2 = dateadd(SECOND, 2, convert(DATETIME, 0))
WAITFOR DELAY @Delay2

A note on waiting for TIME vs DELAY:

Have you ever noticed that if you accidentally pass WAITFOR TIME a date that already passed, even by just a second, it will never return? Check it out:

--Example 3
DECLARE @Time1 DATETIME
SELECT @Time1 = getdate()
WAITFOR DELAY '00:00:01'
WAITFOR TIME @Time1 --WILL HANG FOREVER

Unfortunately, WAITFOR DELAY will do the same thing if you pass it a negative DATETIME value (yes, that's a thing).

--Example 4
DECLARE @Delay3 DATETIME
SELECT @Delay3 = dateadd(SECOND, -1, convert(DATETIME, 0))
WAITFOR DELAY @Delay3 --WILL HANG FOREVER

However, I would still recommend using WAITFOR DELAY over a static time because you can always confirm your delay is positive and it will stay that way for however long it takes your code to reach the WAITFOR statement.

I believe the normal answer is that it should be passed by value if you need to make a copy of it in your function. Pass it by const reference otherwise.

Here is a good discussion: http://cpp-next.com/archive/2009/08/want-speed-pass-by-value/

i used this and it works fine without finish()

startActivity(getIntent());

Code I have used for IE 11 without jquery and just for a single textarea:

Javascript:

// Impede que o comentário tenha mais de num_max caracteres
var internalChange= 0; // important, prevent reenter
function limit_char(max)
{ 
    if (internalChange == 1)
    {
        internalChange= 0;
        return;
    }
    internalChange= 1;
    // <form> and <textarea> are the ID's of your form and textarea objects
    <form>.<textarea>.value= <form>.<textarea>.value.substring(0,max);
}

and html:

<TEXTAREA onpropertychange='limit_char(5)' ...

If you're not looking to download dex2jar, then just use the apk_grabber python script to decompile any apk into jar files. Then you read them with jd-gui.

You'll find the junit launch commands in .metadata/.plugins/org.eclipse.debug.core/.launches, assuming your Eclipse works like mine does. The files are named {TestClass}.launch.

You will probably also need the .classpath file in the project directory that contains the test class.

Like the run configurations, they're XML files (even if they don't have an xml extension).

If you have to click OK after entering your passcode, this command will unlock your phone:

adb shell input text XXXX && adb shell input keyevent 66

Where

• XXXX is your passcode.
• 66 is keycode of button OK.
• adb shell input text XXXX will enter your passcode.
• adb shell input keyevent 66 will simulate click the OK button

A regular REST API uses HTTP as the underlying protocol for communication, which follows the request and response paradigm, meaning the communication involves the client requesting some data or resource from a server, and the server responding back to that client. However, HTTP is a stateless protocol, so every request-response cycle will end up having to repeat the header and metadata information. This incurs additional latency in case of frequently repeated request-response cycles.

With WebSockets, although the communication still starts off as an initial HTTP handshake, it is further upgraded to follow the WebSockets protocol (i.e. if both the server and the client are compliant with the protocol as not all entities support the WebSockets protocol).

Now with WebSockets, it is possible to establish a full-duplex and persistent connection between the client and a server. This means that unlike a request and a response, the connection stays open for as long as the application is running (i.e. it’s persistent), and since it is full-duplex, two-way simultaneous communication is possible i.e now the server is capable of initiating communication and 'push' some data to the client when new data (that the client is interested in) becomes available.

The WebSockets protocol is stateful and allows you to implement the Publish-Subscribe (or Pub/Sub) messaging pattern which is the primary concept used in the real-time technologies where you are able to get new updates in the form of server push without the client having to request (refresh the page) repeatedly. Examples of such applications are Uber car's location tracking, Push Notifications, Stock market prices updating in real-time, chat, multiplayer games, live online collaboration tools, etc.

You can check out a deep dive article on Websockets which explains the history of this protocol, how it came into being, what it’s used for and how you can implement it yourself.

Here's a video from a presentation I did about WebSockets and how they are different from using the regular REST APIs: Standardisation and leveraging the exponential rise in data streaming

This XML file does not appear to have any style information associated with it. The document tree is shown below.

You will get this error in the client side when the client (the webbrowser) for some reason interprets the HTTP response content as text/xml instead of text/html and the parsed XML tree doesn't have any XML-stylesheet. In other words, the webbrowser incorrectly parsed the retrieved HTTP response content as XML instead of as HTML due to the wrong or missing HTTP response content type.

In case of JSF/Facelets files which have the default extension of .xhtml, that can in turn happen if the HTTP request hasn't invoked the FacesServlet and thus it wasn't able to parse the Facelets file and generate the desired HTML output based on the XHTML source code. Firefox is then merely guessing the HTTP response content type based on the .xhtml file extension which is in your Firefox configuration apparently by default interpreted as text/xml.

You need to make sure that the HTTP request URL, as you see in browser's address bar, matches the <url-pattern> of the FacesServlet as registered in webapp's web.xml, so that it will be invoked and be able to generate the desired HTML output based on the XHTML source code. If it's for example *.jsf, then you need to open the page by /some.jsf instead of /some.xhtml. Alternatively, you can also just change the <url-pattern> to *.xhtml. This way you never need to fiddle with virtual URLs.

See also:

• JSF Facelets: Sometimes I see the URL is .jsf and sometimes .xhtml. Why?

Note thus that you don't actually need a XML stylesheet. This all was just misinterpretation by the webbrowser while trying to do its best to make something presentable out of the retrieved HTTP response content. It should actually have retrieved the properly generated HTML output, Firefox surely knows precisely how to deal with HTML content.

Kibana doesn't have a log file by default. but you can set it up using log_file Kibana server property - https://www.elastic.co/guide/en/kibana/current/kibana-server-properties.html

Here is my global module I use -

var Cookie = {   

   Create: function (name, value, days) {

       var expires = "";

        if (days) {
           var date = new Date();
           date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000));
           expires = "; expires=" + date.toGMTString();
       }

       document.cookie = name + "=" + value + expires + "; path=/";
   },

   Read: function (name) {

        var nameEQ = name + "=";
        var ca = document.cookie.split(";");

        for (var i = 0; i < ca.length; i++) {
            var c = ca[i];
            while (c.charAt(0) == " ") c = c.substring(1, c.length);
            if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
        }

        return null;
    },

    Erase: function (name) {

        Cookie.create(name, "", -1);
    }

};

You can achieve what you want by defining a footer for the tableview. See this answer for more details:Eliminate Extra separators below UITableView

I had a similar issue. The accepted answer did not work for me, until I made the change: @PrepareForTest(TheClassThatContainsStaticMethod.class), according to PowerMock's documentation for mockStatic.

And I don't have to use BDDMockito.

My class:

public class SmokeRouteBuilder {
    public static String smokeMessageId() {
        try {
            return InetAddress.getLocalHost().getHostAddress();
        } catch (UnknownHostException e) {
            log.error("Exception occurred while fetching localhost address", e);
            return UUID.randomUUID().toString();
        }
    }
}

My test class:

@RunWith(PowerMockRunner.class)
@PrepareForTest(SmokeRouteBuilder.class)
public class SmokeRouteBuilderTest {
    @Test
    public void testSmokeMessageId_exception() throws UnknownHostException {
        UUID id = UUID.randomUUID();

        mockStatic(InetAddress.class);
        mockStatic(UUID.class);
        when(InetAddress.getLocalHost()).thenThrow(UnknownHostException.class);
        when(UUID.randomUUID()).thenReturn(id);

        assertEquals(id.toString(), SmokeRouteBuilder.smokeMessageId());
    }
}

If you need 5 random numbers between 1 and 15, you should do:

var_dump(getRandomNumbers(1, 15, 5));

function getRandomNumbers($min, $max, $count)
{
    if ($count > (($max - $min)+1))
    {
        return false;
    }
    $values = range($min, $max);
    shuffle($values);
    return array_slice($values,0, $count);
}

It will return false if you specify a count value larger then the possible range of numbers.

Eclipse by default does not know about your external Maven installation and uses the embedded one. Therefore in order for Eclipse to use your global settings you need to set it in menu Settings ? Maven ? Installations.

Copy host keys from both bitbucket and github:

ssh root@deployserver 'echo "$(ssh-keyscan -t rsa,dsa bitbucket.org)" >> /root/.ssh/known_hosts'
ssh root@deployserver 'echo "$(ssh-keyscan -t rsa,dsa github.com)" >> /root/.ssh/known_hosts'

You want the (standard) POSIXt type from base R that can be had in 'compact form' as a POSIXct (which is essentially a double representing fractional seconds since the epoch) or as long form in POSIXlt (which contains sub-elements). The cool thing is that arithmetic etc are defined on this -- see help(DateTimeClasses)

Quick example:

R> now <- Sys.time()
R> now
[1] "2009-12-25 18:39:11 CST"
R> as.numeric(now)
[1] 1.262e+09
R> now + 10  # adds 10 seconds
[1] "2009-12-25 18:39:21 CST"
R> as.POSIXlt(now)
[1] "2009-12-25 18:39:11 CST"
R> str(as.POSIXlt(now))
 POSIXlt[1:9], format: "2009-12-25 18:39:11"
R> unclass(as.POSIXlt(now))

As for difference, easy too:

R> Jan1 <- strptime("2009-01-01 00:00:00", "%Y-%m-%d %H:%M:%S")
R> difftime(now, Jan1, unit="week")

Lastly, the zoo package is an extremely versatile and well-documented container for matrix with associated date/time indices.

Assume you have one table with name 'table1'. It contain one column 'col1' with varchar type. Query to crate table is give below

CREATE TABLE `table1` (
    `col1` VARCHAR(50) NULL DEFAULT NULL
)

Now if you want to insert number from 1 to 50 in that table then use following stored procedure

DELIMITER $$  
CREATE PROCEDURE ABC()

   BEGIN
      DECLARE a INT Default 1 ;
      simple_loop: LOOP         
         insert into table1 values(a);
         SET a=a+1;
         IF a=51 THEN
            LEAVE simple_loop;
         END IF;
   END LOOP simple_loop;
END $$

To call that stored procedure use

CALL `ABC`()

Thought this might help someone in the future.

If you know the property name already, you can do something like the following:

[HttpPost]
[Route("myRoute")]
public object SomeApiControllerMethod([FromBody] dynamic args){
   var stringValue = args.MyPropertyName.ToString();
   //do something with the string value.  If this is an int, we can int.Parse it, or if it's a string, we can just use it directly.
   //some more code here....
   return stringValue;
}

This is the code to link an HTTP(S) accessible PDF from an <iframe>:

<iframe src="https://research.google.com/pubs/archive/44678.pdf"
   width="800" height="600">

Fiddle: http://jsfiddle.net/cEuZ3/1545/

EDIT: and you can use Javascript, from the <a> tag (onclick event) to set iFrame' SRC attribute at run-time...

EDIT 2: Apparently, it is a bug (but there are workarounds):

PDF files do not open in Internet Explorer with Adobe Reader 10.0 - users get an empty gray screen. How can I fix this for my users?

As Gary's Student mentioned, you would need to remove the dot before Cells to make the code work as you originally wrote it. I can't be sure, since you only included the one line of code, but the error you got when you deleted the dots might have something to do with how you defined your variables.

I ran your line of code with the variables defined as integers and it worked:

Sub TestClearLastColumn()

    Dim LastColData As Long
        Set LastColData = Range("A1").End(xlToRight).Column

    Dim LastRowData As Long
        Set LastRowData = Range("A1").End(xlDown).Row

    Worksheets("Sheet1").Range(Cells(2, LastColData), Cells(LastRowData, LastColData)).ClearContents

End Sub

I don't think a With statement is appropriate to the line of code you shared, but if you were to use one, the With would be at the start of the line that defines the object you are manipulating. Here is your code rewritten using an unnecessary With statement:

With Worksheets("Sheet1").Range(Cells(2, LastColData), Cells(LastRowData, LastColData))
    .ClearContents
End With

With statements are designed to save you from retyping code and to make your coding easier to read. It becomes useful and appropriate if you do more than one thing with an object. For example, if you wanted to also turn the column red and add a thick black border, you might use a With statement like this:

With Worksheets("Sheet1").Range(Cells(2, LastColData), Cells(LastRowData, LastColData))
    .ClearContents
    .Interior.Color = vbRed
    .BorderAround Color:=vbBlack, Weight:=xlThick
End With

Otherwise you would have to declare the range for each action or property, like this:

    Worksheets("Sheet1").Range(Cells(2, LastColData), Cells(LastRowData, LastColData)).ClearContents
    Worksheets("Sheet1").Range(Cells(2, LastColData), Cells(LastRowData, LastColData)).Interior.Color = vbRed
    Worksheets("Sheet1").Range(Cells(2, LastColData), Cells(LastRowData, LastColData)).BorderAround Color:=vbBlack, Weight:=xlThick

I hope this gives you a sense for why Gary's Student believed the compiler might be expecting a With (even though it was inappropriate) and how and when a With can be useful in your code.

I suggest you using bootstrap which works perfectly:

What you have is correct, though you will not call it global, it is a class attribute and can be accessed via class e.g Shape.lolwut or via an instance e.g. shape.lolwut but be careful while setting it as it will set an instance level attribute not class attribute

class Shape(object):
    lolwut = 1

shape = Shape()

print Shape.lolwut,  # 1
print shape.lolwut,  # 1

# setting shape.lolwut would not change class attribute lolwut 
# but will create it in the instance
shape.lolwut = 2

print Shape.lolwut,  # 1
print shape.lolwut,  # 2

# to change class attribute access it via class
Shape.lolwut = 3

print Shape.lolwut,  # 3
print shape.lolwut   # 2 

output:

1 1 1 2 3 2

Somebody may expect output to be 1 1 2 2 3 3 but it would be incorrect

Which version of IntelliJ are you using? Note that since last year, IntelliJ exists in two versions:

• Ultimate Edition, which is the complete IDE
• Community Edition, which is free but does not support JavaEE developments.

(see differences here)

In case you are using the Community Edition, you will not be able to manage a Tomcat installation.

In case you are using the Ultimate Edition, you can have a look at:

• The FAQ for Netbeans users (see question How do I configure a web framework for my project?).
• IntelliJ Ultimate edition "Help": Run/Debug Configuration: Tomcat Server

Generally, I'd prefer not using GoTo for bad readability. To me, it's a bad excuse for programming simple iterative functions instead of having to program recursive functions, or even better (if things like a Stack Overflow is feared), their true iterative alternatives (which may sometimes be complex).

Something like this would do:

while(true) {
   alert("RINSE");
   alert("LATHER");
}

That right there is an infinite loop. The expression ("true") inside the parantheses of the while clause is what the Javascript engine will check for - and if the expression is true, it'll keep the loop running. Writing "true" here always evaluates to true, hence an infinite loop.

SELECT * 
FROM reservations 
WHERE arrival >= '2012-01-01'
AND arrival < '2013-01-01'
   ;

BTW if the distribution of values indicates that an index scan will not be the worth (for example if all the values are in 2012), the optimiser could still choose a full table scan. YMMV. Explain is your friend.
