Programs & Examples On #Date difference

To remove the 'days' text element, you can also make use of the dt() accessor for series: https://pandas.pydata.org/pandas-docs/stable/generated/pandas.Series.dt.html

So,

df[['A','B']] = df[['A','B']].apply(pd.to_datetime) #if conversion required
df['C'] = (df['B'] - df['A']).dt.days

which returns:

             A          B   C
one 2014-01-01 2014-02-28  58
two 2014-02-03 2014-03-01  26

let calendar = NSCalendar.currentCalendar();
let component1 = calendar.component(.Day, fromDate: fromDate)
let component2 = calendar.component(.Day, fromDate: toDate)
let difference  = component1 - component2

You can use DAYS.between from java.time.temporal.ChronoUnit

e.g.

import java.time.temporal.ChronoUnit;

public long getDaysCountBetweenDates(LocalDate dateBefore, LocalDate dateAfter) {
    return DAYS.between(dateBefore, dateAfter);
}

realpath isn't available on all linux flavors, but readlink should be.

readlink -f symlinkName

The above should do the trick.

Alternatively, if you don't have either of the above installed, you can do the following if you have python 2.6 (or later) installed

python -c 'import os.path; print(os.path.realpath("symlinkName"))'

I had the same issue as above and I am using PostgreSQL 10.5. I tried everything as above but nothing seems to be working.

Then I closed the pgadmin and opened a session for the PSQL terminal. Logged into the PSQL and connected to the database and schema respectively :

\c <DATABASE_NAME>;
set search_path to <SCHEMA_NAME>;

Then, restarted the pgadmin console and then I was able to work without issue in the query-tool of the pagadmin.

For 2 and more left joins (left joining creatorUser and initiatorUser )

IQueryable<CreateRequestModel> queryResult = from r in authContext.Requests
                                             join candidateUser in authContext.AuthUsers
                                             on r.CandidateId equals candidateUser.Id
                                             join creatorUser in authContext.AuthUsers
                                             on r.CreatorId equals creatorUser.Id into gj
                                             from x in gj.DefaultIfEmpty()
                                             join initiatorUser in authContext.AuthUsers
                                             on r.InitiatorId equals initiatorUser.Id into init
                                             from x1 in init.DefaultIfEmpty()

                                             where candidateUser.UserName.Equals(candidateUsername)
                                             select new CreateRequestModel
                                             {
                                                 UserName = candidateUser.UserName,
                                                 CreatorId = (x == null ? String.Empty : x.UserName),
                                                 InitiatorId = (x1 == null ? String.Empty : x1.UserName),
                                                 CandidateId = candidateUser.UserName
                                             };

Overide the dismiss() method like this:

@Override
public void dismiss() {
    Window window = getWindow();
    if (window == null) {
        return;
    }
    View decor = window.getDecorView();
    if (decor != null && decor.getParent() != null) {
        super.dismiss();
    }
}

To reproduce the issue, just finish activity before dismiss dialog.

Change your code to

document.write("<td width='74'><button id='button' type='button' onclick='myfunction(\""+ name + "\")'>click</button></td>")

If you are using a version of enthought python (EPD) you might want to go directly to your site-packages and reinstall numpy. Then try to install pandas with pip. You will have to modify your installation prefix for that.

If the problem persists (as it did with me) try downloading pandas tar ball, unpack it in your site packages and run setup.py install from your pandas directory.

If you got your dependencies right you can import pandas and check it imports smoothly.

It seems that if you specify table-layout: fixed; on the table element, then your styles for td should take effect. This will also affect how the cells are sized, though.

Sitepoint discusses the table-layout methods a little here: http://reference.sitepoint.com/css/tableformatting

You'll have to actually USE jQuery to build the div, if you want to write maintainable or usable code.

//create a div
var $newDiv = $('<div>');

//set the id
$newDiv.attr("id","myId");

The length function will do it. See http://www.techonthenet.com/oracle/functions/length.php

Bubbling

  Event propagate to the upto root element is **BUBBLING**.

Capturing

  Event propagate from body(root) element to eventTriggered Element is **CAPTURING**.

As pointed out by other answers, in python they return floats probably because of historical reasons to prevent overflow problems. However, they return integers in python 3.

>>> import math
>>> type(math.floor(3.1))
<class 'int'>
>>> type(math.ceil(3.1))
<class 'int'>

You can find more information in PEP 3141.

No, you can't undo, rollback or reverse a commit.

STOP THE DATABASE!

(Note: if you deleted the data directory off the filesystem, do NOT stop the database. The following advice applies to an accidental commit of a DELETE or similar, not an rm -rf /data/directory scenario).

If this data was important, STOP YOUR DATABASE NOW and do not restart it. Use pg_ctl stop -m immediate so that no checkpoint is run on shutdown.

You cannot roll back a transaction once it has commited. You will need to restore the data from backups, or use point-in-time recovery, which must have been set up before the accident happened.

If you didn't have any PITR / WAL archiving set up and don't have backups, you're in real trouble.

Urgent mitigation

Once your database is stopped, you should make a file system level copy of the whole data directory - the folder that contains base, pg_clog, etc. Copy all of it to a new location. Do not do anything to the copy in the new location, it is your only hope of recovering your data if you do not have backups. Make another copy on some removable storage if you can, and then unplug that storage from the computer. Remember, you need absolutely every part of the data directory, including pg_xlog etc. No part is unimportant.

Exactly how to make the copy depends on which operating system you're running. Where the data dir is depends on which OS you're running and how you installed PostgreSQL.

Ways some data could've survived

If you stop your DB quickly enough you might have a hope of recovering some data from the tables. That's because PostgreSQL uses multi-version concurrency control (MVCC) to manage concurrent access to its storage. Sometimes it will write new versions of the rows you update to the table, leaving the old ones in place but marked as "deleted". After a while autovaccum comes along and marks the rows as free space, so they can be overwritten by a later INSERT or UPDATE. Thus, the old versions of the UPDATEd rows might still be lying around, present but inaccessible.

Additionally, Pg writes in two phases. First data is written to the write-ahead log (WAL). Only once it's been written to the WAL and hit disk, it's then copied to the "heap" (the main tables), possibly overwriting old data that was there. The WAL content is copied to the main heap by the bgwriter and by periodic checkpoints. By default checkpoints happen every 5 minutes. If you manage to stop the database before a checkpoint has happened and stopped it by hard-killing it, pulling the plug on the machine, or using pg_ctl in immediate mode you might've captured the data from before the checkpoint happened, so your old data is more likely to still be in the heap.

Now that you have made a complete file-system-level copy of the data dir you can start your database back up if you really need to; the data will still be gone, but you've done what you can to give yourself some hope of maybe recovering it. Given the choice I'd probably keep the DB shut down just to be safe.

Recovery

You may now need to hire an expert in PostgreSQL's innards to assist you in a data recovery attempt. Be prepared to pay a professional for their time, possibly quite a bit of time.

I posted about this on the Pg mailing list, and ?????? ?????? linked to depesz's post on pg_dirtyread, which looks like just what you want, though it doesn't recover TOASTed data so it's of limited utility. Give it a try, if you're lucky it might work.

See: pg_dirtyread on GitHub.

I've removed what I'd written in this section as it's obsoleted by that tool.

Prevention

See my blog entry Preventing PostgreSQL database corruption.

On a semi-related side-note, if you were using two phase commit you could ROLLBACK PREPARED for a transction that was prepared for commit but not fully commited. That's about the closest you get to rolling back an already-committed transaction, and does not apply to your situation.

There can be several things which cause this.

1. Make sure you've write the correct version in targetSdkVersion and compileSdkVersion.
2. Make sure targetSdkVersion and compileSdkVersion are same.

Other solutions can be:

1. Invalidate caches & restart Android Studio from File ? Invalidate Caches / Restarts...
2. Clean your project from Build ? Clean Project
3. Rebuild project from Build ? Rebuild Project
4. Make project from Build ? Make Project [this process may take some time]

It`s possible to use MySQL specific syntax sugar:

SELECT ... date_field + INTERVAL 1 DAY

Looks much more pretty instead of DATE_ADD function

A more readable version of bkbilly's answer:

svn st | awk '/^?/{print $2}' > svnignore.txt
svn propget svn:ignore >> svnignore.txt
svn propset svn:ignore -F svnignore.txt .
rm svnignore.txt

What it does:

1. Gets the status files from the svn
2. Saves all files with ? to the file "svnignore.txt"
3. Gets the already ignored files and appends them to the file "svnignore.txt"
4. Tells the svn to ignore the files in "svnignore.txt"
5. Removes the file

If you don't want to rely on a javascript library, you can use document.write() to spit out the required css, wrapped in style tags, straight into the document head:

<head>
  <script type="text/javascript">
    document.write("<style>body { background-color:#000 }</style>");
  </script>
  # other stuff..
</head>

This way you avoid firing an extra HTTP request.

There are other solutions that have been suggested / added / removed, but I don't see any point in overcomplicating something that already works fine cross-browser. Good luck!

In my experience the pythonw.exe is faster at least with using pygame.

If this is for some configuration file processing, consider using Apache configuration. https://commons.apache.org/proper/commons-configuration/javadocs/v1.10/apidocs/index.html?org/apache/commons/configuration/PropertiesConfiguration.html It has way to multiple values to single key- The format is bit different though

key=value1,value2,valu3 gives three values against same key.

A simple formula to use is

=COUNTIF($B:$B,A1)

Formula specified is for cell A1. Simply copy and paste special - format to the whole of column A

Not to the point of the question (can be related though), but, if you bootstrap a new project and wondering why do you get the same error, it may come from the artifactId of spring-boot-starter-data-jpa in the dependency section. I gave the dependency below. You will need to define the database to get rid of this.

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

It's impossible to say without seeing your actual code. Likely the reason is a code path through your function that doesn't execute a return statement. When the code goes down that path, the function ends with no value returned, and so returns None.

Updated: It sounds like your code looks like this:

def b(self, p, data): 
    current = p 
    if current.data == data: 
        return True 
    elif current.data == 1:
        return False 
    else: 
        self.b(current.next, data)

That else clause is your None path. You need to return the value that the recursive call returns:

    else:
        return self.b(current.next, data)

BTW: using recursion for iterative programs like this is not a good idea in Python. Use iteration instead. Also, you have no clear termination condition.

Using the InstallCert to generate the jssecacerts file and do -Djavax.net.ssl.trustStore=/path/to/jssecacerts worked great.

Try:

cursor.column_names

mysql connector version:

mysql.connector.__version__
'2.2.9'

You can use while(in.available() != 0) instead of while(true).

I'm the OP. After some research and testing, the answer is:

No, there is no way to do exactly that.

The execmgr.log will show the commandline and ccmcache folder used for installation. Typically, required apps don't show on appenforce.log and some clients will have outdated appenforce or no ppenforce.log files. execmgr.log also shows required hidden uninstall actions as well.

You may want to save the blog link. I still reference it from time to time.

Why not using Cakes Response Class? You can set the status code of the response simply by this:

$this->response->statusCode(200);

Then just render a file with the error message, which suits best with JSON.

$str = "Hello there folks!"
$str_ex = explode("there, $str, 2);   //explodes $string just twice
                                      //outputs: array ("Hello ", " folks")
$str_final = implode("", $str_ex);    // glues above array together
                                      // outputs: str("Hello  folks")

There is one more additional space but it didnt matter as it was for backgound script in my case.

If you are trying to embed external js scripts to the vue.js component template, follow below:

I wanted to add a external javascript embed code to my component like this:

<template>
  <div>
    This is my component
    <script src="https://badge.dimensions.ai/badge.js"></script>
  </div>
<template>

And Vue showed me this error:

Templates should only be responsible for mapping the state to the UI. Avoid placing tags with side-effects in your templates, such as , as they will not be parsed.

The way I solved it was by adding type="application/javascript" (See this question to learn more about MIME type for js):

<script type="application/javascript" defer src="..."></script>

You may notice the defer attribute. If you want to learn more watch this video by Kyle

The $.grep() method eliminates items from an array as necessary so that only remaining items carry a given search. The test is a function that is passed an array item and the index of the item within the array. Only if the test returns true will the item be in the result array.

a little more generic answer of jelde015 (credit to him of course)

for updating the loading bar manually will be:

import sys
from math import *


def loadingBar(i, N, size):
    percent = float(i) / float(N)
    sys.stdout.write("\r"
                     + str(int(i)).rjust(3, '0')
                     +"/"
                     +str(int(N)).rjust(3, '0')
                     + ' ['
                     + '='*ceil(percent*size)
                     + ' '*floor((1-percent)*size)
                     + ']')

and calling it by:

loadingBar(7, 220, 40)

will result:

007/220 [=                                       ]  

just call it whenever you want with the current i value.

set the size as the number of chars the bar should be

I had ran into similar problem today. Tried all the above solutions but didn't worked. So posting my solution here.

First read the image as an array

image = plt.imread(//image_path)
plt.imshow(image)

From MSDN:

Top-level types, which are not nested in other types, can only have internal or public accessibility. The default accessibility for these types is internal.

I found using JSON works but watch our for circular references

var newInstance = JSON.parse(JSON.stringify(firstInstance));

Another option is to not read things in character by character -- read the entire file into memory. This is useful if you need to look at the characters more than once. One trivial way to do that is:

  /** Read the contents of a file into a string buffer      */
    public static void readFile(File file, StringBuffer buf)
        throws IOException
    {
    FileReader fr = null;
    try {
      fr = new FileReader(file);
      BufferedReader br = new BufferedReader(fr);
      char[] cbuf = new char[(int) file.length()];
      br.read(cbuf);  
      buf.append(cbuf);
      br.close();
    }
    finally {
      if (fr != null) {
        fr.close();
      }
    }
}

instead of

$('html, body').animate({scrollTop:xxx}, 'slow');

use

$('html, body').animate({scrollTop:$('#div_id').position().top}, 'slow');

this will return the absolute top position of whatever element you select as #div_id

Make certain that all the heap memory is successfully freed. There is no need if you never allocate memory on the heap. If you do, count the number of times you malloc memory, and count up the number of time you free memory.

Excel + SQLCMD + Perl = exceltomssqlinsert

This was extremely helpful for me when trying to automate Cisco SIP phone configuration using an Excel spreadsheet as the source. My only issue was when I tried to make an array and populate it using $array | Add-Member ... as I needed to use it later on to generate the config file. Just defining an array and making it the for loop allowed it to store correctly.

$lastCell = 11 
$startRow, $model, $mac, $nOF, $ext = 1, 1, 5, 6, 7

$excel = New-Object -ComObject excel.application
$wb = $excel.workbooks.open("H:\Strike Network\Phones\phones.xlsx")
$sh = $wb.Sheets.Item(1)
$endRow = $sh.UsedRange.SpecialCells($lastCell).Row

$phoneData = for ($i=1; $i -le $endRow; $i++)
            {
                $pModel = $sh.Cells.Item($startRow,$model).Value2
                $pMAC = $sh.Cells.Item($startRow,$mac).Value2
                $nameOnPhone = $sh.Cells.Item($startRow,$nOF).Value2
                $extension = $sh.Cells.Item($startRow,$ext).Value2
                New-Object PSObject -Property @{ Model = $pModel; MAC = $pMAC; NameOnPhone = $nameOnPhone; Extension = $extension }
                $startRow++
            }

I used to have no issues adding information to an array with Add-Member but that was back in PSv2/3, and I've been away from it a while. Though the simple solution saved me manually configuring 100+ phones and extensions - which nobody wants to do.

Why not write one? Something like this may satisfy your requirements:

def FixCase(st):
    return ' '.join(''.join([w[0].upper(), w[1:].lower()]) for w in st.split())

For ASP.NET use WebConfigurationManager:

What would be handy would be to apply the Camera position to a new plot. So I plot, then move the plot around with the mouse changing the distance. Then try to replicate the view including the distance on another plot. I find that axx.ax.get_axes() gets me an object with the old .azim and .elev.

IN PYTHON...

axx=ax1.get_axes()
azm=axx.azim
ele=axx.elev
dst=axx.dist       # ALWAYS GIVES 10
#dst=ax1.axes.dist # ALWAYS GIVES 10
#dst=ax1.dist      # ALWAYS GIVES 10

Later 3d graph...

ax2.view_init(elev=ele, azim=azm) #Works!
ax2.dist=dst                       # works but always 10 from axx

EDIT 1... OK, Camera position is the wrong way of thinking concerning the .dist value. It rides on top of everything as a kind of hackey scalar multiplier for the whole graph.

This works for the magnification/zoom of the view:

xlm=ax1.get_xlim3d() #These are two tupples
ylm=ax1.get_ylim3d() #we use them in the next
zlm=ax1.get_zlim3d() #graph to reproduce the magnification from mousing
axx=ax1.get_axes()
azm=axx.azim
ele=axx.elev

Later Graph...

ax2.view_init(elev=ele, azim=azm) #Reproduce view
ax2.set_xlim3d(xlm[0],xlm[1])     #Reproduce magnification
ax2.set_ylim3d(ylm[0],ylm[1])     #...
ax2.set_zlim3d(zlm[0],zlm[1])     #...

In latest version (1.0RC) of TypeScript, you can use enums like this:

enum States {
    New,
    Active,
    Disabled
} 

// this will show message '0' which is number representation of enum member
alert(States.Active); 

// this will show message 'Disabled' as string representation of enum member
alert(States[States.Disabled]);

Update 1

To get number value of enum member from string value, you can use this:

var str = "Active";
// this will show message '1'
alert(States[str]);

Update 2

In latest TypeScript 2.4, there was introduced string enums, like this:

enum ActionType {
    AddUser = "ADD_USER",
    DeleteUser = "DELETE_USER",
    RenameUser = "RENAME_USER",

    // Aliases
    RemoveUser = DeleteUser,
}

For more info about TypeScript 2.4, read blog on MSDN.

All the answers are good, but I found they all lacked that professional "polish".

I came up with this, fading out, sliding up, then removing:

$target.fadeTo(1000, 0.01, function(){ 
    $(this).slideUp(150, function() {
        $(this).remove(); 
    }); 
});

As of April 16, 2015, with the release of R 3.2.0 there's a new function called dir.exists(). To use this function and create the directory if it doesn't exist, you can use:

ifelse(!dir.exists(file.path(mainDir, subDir)), dir.create(file.path(mainDir, subDir)), FALSE)

This will return FALSE if the directory already exists or is uncreatable, and TRUE if it didn't exist but was succesfully created.

Note that to simply check if the directory exists you can use

dir.exists(file.path(mainDir, subDir))

You already have an old copy of that database installed in Server Explorer. So its a simple naming collision in the Server Object Explorer / SQL server. You likely created the same database Catalog Name already before you decided to move it to the Apps_Data folder. So that Database name already exists and just needs to be deleted.

Just go into Visual Studio > View > SQL Server Object Explorer and delete the old database name and its connection. Retry your app again and it should install the .mdf file in App_Data and create the same exact database again in the Server Explorer.

I recommend checking out mongosniff. This can tool can do everything you want and more. Especially it can help diagnose issues with larger scale mongo systems and how queries are being routed and where they are coming from since it works by listening to your network interface for all mongo related communications.

To resolve the following error I was facing to install docker-ce on RHEL-7

Error: Package: 3:docker-ce-18.09.5-3.el7.x86_64 (docker-ce-stable)
           Requires: container-selinux >= 2.9
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Please run following command before installing latest version of docker-ce

yum install -y http://mirror.centos.org/centos/7/extras/x86_64/Packages/container-selinux-2.68-1.el7.noarch.rpm

Once previous command runs successfully then install docker-ce with following command

yum -y install docker-ce

once installation is done then run

systemctl start docker

Note : Run all these commands with root user

The following should work but it wouldn't be SEO compatible. It's best to put the title in the title tag.

<script type="text/javascript">

    $(document).ready(function() {

    });

Android NDK official hello-libs CMake example

https://github.com/googlesamples/android-ndk/tree/840858984e1bb8a7fab37c1b7c571efbe7d6eb75/hello-libs

Just worked for me on Ubuntu 17.10 host, Android Studio 3, Android SDK 26, so I strongly recommend that you base your project on it.

The shared library is called libgperf, the key code parts are:

• hello-libs/app/src/main/cpp/CMakeLists.txt:

  // -L
  add_library(lib_gperf SHARED IMPORTED)
  set_target_properties(lib_gperf PROPERTIES IMPORTED_LOCATION
            ${distribution_DIR}/gperf/lib/${ANDROID_ABI}/libgperf.so)
  
  // -I
  target_include_directories(hello-libs PRIVATE
                             ${distribution_DIR}/gperf/include)
  // -lgperf
  target_link_libraries(hello-libs
                        lib_gperf)
  

• app/build.gradle:

  android {
      sourceSets {
          main {
              // let gradle pack the shared library into apk
              jniLibs.srcDirs = ['../distribution/gperf/lib']
  

  Then, if you look under /data/app on the device, libgperf.so will be there as well.

• on C++ code, use: #include <gperf.h>

• header location: hello-libs/distribution/gperf/include/gperf.h

• lib location: distribution/gperf/lib/arm64-v8a/libgperf.so

• If you only support some architectures, see: Gradle Build NDK target only ARM

The example git tracks the prebuilt shared libraries, but it also contains the build system to actually build them as well: https://github.com/googlesamples/android-ndk/tree/840858984e1bb8a7fab37c1b7c571efbe7d6eb75/hello-libs/gen-libs

Try this code, I used the following code for cloning and removing the cloned element, i have also used new class (newClass) which can be added automatically with the newly cloned html

for cloning..

 $(".tr_clone_add").live('click', function() {
    var $tr    = $(this).closest('.tr_clone');
    var newClass='newClass';
    var $clone = $tr.clone().addClass(newClass);
    $clone.find(':text').val('');
    $tr.after($clone);
});

for removing the clone element.

$(".tr_clone_remove").live('click', function() { //Once remove button is clicked
    $(".newClass:last").remove(); //Remove field html
    x--; //Decrement field counter
});

html is as followinng

<tr class="tr_clone">
                       <!-- <td>1</td>-->
                        <td><input type="text" class="span12"></td>
                        <td><input type="text" class="span12"></td>
                        <td><input type="text" class="span12"></td>
                        <td><input type="text" class="span12"></td>
                        <td><input type="text" class="span10" readonly>
                        <span><a href="javascript:void(0);" class="tr_clone_add" title="Add field"><span><i class="icon-plus-sign"></i></span></a> <a href="javascript:void(0);" class="tr_clone_remove" title="Remove field"><span style="color: #D63939;"><i class="icon-remove-sign"></i></span></a> </span> </td> </tr>

In Solution Explorer, please select files you want to copied to output directory and assign two properties: - Build action = Content - Copy to Output Directory = Copy Always

This will do the trick.

If you run Linux and have the extension you could simply read the MIME type from /etc/mime.types by making a hash array. You can then store that in memory and simply call the MIME by array key :)

/**
 * Helper function to extract all mime types from the default Linux /etc/mime.types
 */
function get_mime_types() {
    $mime_types = array();
    if (
        file_exists('/etc/mime.types') &&
        ($fh = fopen('/etc/mime.types', 'r')) !== false
    ) {
        while (($line = fgets($fh)) !== false) {
            if (!trim($line) || substr($line, 0, 1) === '#') continue;
            $mime_type = preg_split('/\t+/', rtrim($line));
            if (
                is_array($mime_type) &&
                isset($mime_type[0]) && $mime_type[0] &&
                isset($mime_type[1]) && $mime_type[1]
            ) {
                foreach (explode(' ', $mime_type[1]) as $ext) {
                    $mime_types[$ext] = $mime_type[0];
                }
            }
        }
        fclose($fh);
    }
    return $mime_types;
}

Code for printing the entire history:

Python 3

One-liner (quick copy and paste):

import readline; print('\n'.join([str(readline.get_history_item(i + 1)) for i in range(readline.get_current_history_length())]))

(Or longer version...)

import readline
for i in range(readline.get_current_history_length()):
    print (readline.get_history_item(i + 1))

Python 2

One-liner (quick copy and paste):

import readline; print '\n'.join([str(readline.get_history_item(i + 1)) for i in range(readline.get_current_history_length())])

(Or longer version...)

import readline
for i in range(readline.get_current_history_length()):
    print readline.get_history_item(i + 1)

Note: get_history_item() is indexed from 1 to n.

Click "View Detail..." a window will open where you can expand the "Inner Exception" my guess is that when you try to delete the record there is a reference constraint violation. The inner exception will give you more information on that so you can modify your code to remove any references prior to deleting the record.

Replace this:

c1.set(Calendar.HOUR, d1.getHours());

with this:

c1.set(Calendar.HOUR_OF_DAY, d1.getHours());

Calendar.HOUR is strictly for 12 hours.

The major issue might be the oracle database itself may not have started. So, you need to manually go via

run command -> services.msc

check for OracleXEService surely, it may be disabled

right click go to properties-> set it to Automatic and press Ok. Then just right click again and start.

This will start your database making you to connect to it

Finally, In sqlplus command line,

connect as sysdba

enter username as admin

then press enter, you'll be connected

Inverse of a matrix using python and numpy:

>>> import numpy as np
>>> b = np.array([[2,3],[4,5]])
>>> np.linalg.inv(b)
array([[-2.5,  1.5],
       [ 2. , -1. ]])

Not all matrices can be inverted. For example singular matrices are not Invertable:

>>> import numpy as np
>>> b = np.array([[2,3],[4,6]])
>>> np.linalg.inv(b)

LinAlgError: Singular matrix

Solution to singular matrix problem:

try-catch the Singular Matrix exception and keep going until you find a transform that meets your prior criteria AND is also invertable.

Intuition for why matrix inversion can't always be done; like in singular matrices:

Imagine an old overhead film projector that shines a bright light through film onto a white wall. The pixels in the film are projected to the pixels on the wall.

If I stop the film projection on a single frame, you will see the pixels of the film on the wall and I ask you to regenerate the film based on what you see. That's easy, you say, just take the inverse of the matrix that performed the projection. An Inverse of a matrix is the reversal of the projection.

Now imagine if the projector was corrupted, and I put a distorted lens in front of the film. Now multiple pixels are projected to the same spot on the wall. I asked you again to "undo this operation with the matrix inverse". You say: "I can't because you destroyed information with the lens distortion, I can't get back to where we were, because the matrix is either Singular or Degenerate."

A matrix that can be used to transform some data into other data is invertable only if the process can be reversed with no loss of information. If your matrix can't be inverted, perhaps you are defining your projection using a guess-and-check methodology rather than using a process that guarantees a non-corrupting transform.

If you're using a heuristic or anything less than perfect mathematical precision, then you'll have to define another process to manage and quarantine distortions so that programming by Brownian motion can resume.

There is also some more detail on the use of <mvc:annotation-driven /> in the Spring docs. In a nutshell, <mvc:annotation-driven /> gives you greater control over the inner workings of Spring MVC. You don't need to use it unless you need one or more of the features outlined in the aforementioned section of the docs.

Also, there are other "annotation-driven" tags available to provide additional functionality in other Spring modules. For example, <transaction:annotation-driven /> enables the use of the @Transaction annotation, <task:annotation-driven /> is required for @Scheduled et al...

tolist() works fine even if encountered a nested array, say a pandas DataFrame;

my_list = [0,1,2,3,4,5,4,3,2,1,0]
my_dt = pd.DataFrame(my_list)
new_list = [i[0] for i in my_dt.values.tolist()]

print(type(my_list),type(my_dt),type(new_list))

It is kind of late, but I looked for e similar filter and ended using something like this:

<div ng-controller="TestCtrl">
 <div ng-repeat="(k,v) in items | filter:{secId: '!!'}">
   {{k}} {{v.pos}}
 </div>
</div>

I my case I fetched an entity without await:

var company = _unitOfWork.Session.GetAsync<Company>(id);

and then I tried to delete it:

await _unitOfWork.Session.DeleteAsync(company);

I could not decipher the error message that I'm deleting a Task<Company> instead of Company:

Did you try to use old good View.clearFocus()

The setReadOnly(state) is very useful for forms, we can set any field to setReadOnly(state) directly or from various condition.But I prefer to use readOnly for setting opacity to the selector otherwise the attr='disabled' also worked like the same way.

readOnly examples:

$('input').setReadOnly(true);

or through the various codition like

var same = this.checked;
$('input').setReadOnly(same);

here we are using the state boolean value to set and remove readonly attribute from the input depending on a checkbox click.

There's an inline alternative also launching a subprocess of bash shell:

timeout 10s bash <<EOT
function echoFooBar {
  echo foo
}

echoFooBar

The reverse() is used to adhere the django DRY principle i.e if you change the url in future then you can reference that url using reverse(urlname).

Use the gca ("get current axes") helper function:

ax = plt.gca()

Example:

import matplotlib.pyplot as plt
import matplotlib.finance
quotes = [(1, 5, 6, 7, 4), (2, 6, 9, 9, 6), (3, 9, 8, 10, 8), (4, 8, 8, 9, 8), (5, 8, 11, 13, 7)]
ax = plt.gca()
h = matplotlib.finance.candlestick(ax, quotes)
plt.show()

I have had to unpack a .ab-file, too and found this post while looking for an answer. My suggested solution is Android Backup Extractor, a free Java tool for Windows, Linux and Mac OS.

Make sure to take a look at the README, if you encounter a problem. You might have to download further files, if your .ab-file is password-protected.

Usage:

java -jar abe.jar [-debug] [-useenv=yourenv] unpack <backup.ab> <backup.tar> [password]

Example:

Let's say, you've got a file test.ab, which is not password-protected, you're using Windows and want the resulting .tar-Archive to be called test.tar. Then your command should be:

java.exe -jar abe.jar unpack test.ab test.tar ""

I was able to read a 4GB log file in about 50 seconds with the following. You may be able to make it faster by loading it as a C# assembly dynamically using PowerShell.

[System.IO.StreamReader]$sr = [System.IO.File]::Open($file, [System.IO.FileMode]::Open)
while (-not $sr.EndOfStream){
    $line = $sr.ReadLine()
}
$sr.Close() 

 select convert_tz(now(),@@session.time_zone,'+05:30')

replace '+05:30' with desired timezone. see here - https://stackoverflow.com/a/3984412/2359994

to format into desired time format, eg:

 select DATE_FORMAT(convert_tz(now(),@@session.time_zone,'+05:30') ,'%b %d %Y %h:%i:%s %p') 

you will get similar to this -> Dec 17 2014 10:39:56 AM

For me, it was the local overrides in Sources -> Overrides. A file gets saved locally whenever you change the styling of a page and chrome uses that file to override the server's css.

this should work fine...

For me, the main difference is that a script is interpreted, while a program is executed (i.e. the source is first compiled, and the result of that compilation is expected).

Wikipedia seems to agree with me on this :

Script :

"Scripts" are distinct from the core code of the application, which is usually written in a different language, and are often created or at least modified by the end-user.
Scripts are often interpreted from source code or bytecode, whereas the applications they control are traditionally compiled to native machine code.

Program :

The program has an executable form that the computer can use directly to execute the instructions.
The same program in its human-readable source code form, from which executable programs are derived (e.g., compiled)

Note that -p is an argument to the mkdir command specifically, not the whole of Unix. Every command can have whatever arguments it needs.

In this case it means "parents", meaning mkdir will create a directory and any parents that don't already exist.

To use DHCP, you'd have to run a DHCP server on the primary and a client on the secondary; the primary could then query the server to find out what address it handed out. Probably overkill.

I can't help you with Windows directly. On Unix, the "arp" command will tell you what IP addresses are known to be attached to the local ethernet segment. Windows will have this same information (since it's a core part of the IP/Ethernet interface) but I don't know how you get at it.

Of course, the networking stack will only know about the other host if it has previously seen traffic from it. You may have to first send a broadcast packet on the interface to elicit some sort of response and thus populate the local ARP table.

Array.prototype.difference = function(e) {
    return this.filter(function(i) {return e.indexOf(i) < 0;});
};

eg:- 

[1,2,3,4,5,6,7].difference( [3,4,5] );  
 => [1, 2, 6 , 7]

If you don't want to have to make the same edits in various places, then roughly do this:

* * * * * . /home/username/.bashrc && yourcommand all of your args

The . space and then the path to .bashrc and the && command are the magic there to get your environment changes into the running bash shell. Too, if you really want the shell to be bash, it is a good idea to have a line in your crontab:

SHELL=/bin/bash

Hope it helps someone!

You can use ngx-format-field. It is a directive to format the input value which will appear in the view. It will not manipulate the Input value which will be saved in the backend. See link here!

Example:

component.html:

<input type="text" formControlName="currency" [appFormatFields]="CURRENCY"
(change)="onChangeCurrency()">

component.ts

onChangeCurrency() {
this.currency.patchValue(this.currency.value);
}

The fact that primitives are signed in Java is irrelevant to how they're represented in memory / transit - a byte is merely 8 bits and whether you interpret that as a signed range or not is up to you. There is no magic flag to say "this is signed" or "this is unsigned".

As primitives are signed the Java compiler will prevent you from assigning a value higher than +127 to a byte (or lower than -128). However, there's nothing to stop you downcasting an int (or short) in order to achieve this:

int i = 200; // 0000 0000 0000 0000 0000 0000 1100 1000 (200)
byte b = (byte) 200; // 1100 1000 (-56 by Java specification, 200 by convention)

/*
 * Will print a negative int -56 because upcasting byte to int does
 * so called "sign extension" which yields those bits:
 * 1111 1111 1111 1111 1111 1111 1100 1000 (-56)
 *
 * But you could still choose to interpret this as +200.
 */
System.out.println(b); // "-56"

/*
 * Will print a positive int 200 because bitwise AND with 0xFF will
 * zero all the 24 most significant bits that:
 * a) were added during upcasting to int which took place silently
 *    just before evaluating the bitwise AND operator.
 *    So the `b & 0xFF` is equivalent with `((int) b) & 0xFF`.
 * b) were set to 1s because of "sign extension" during the upcasting
 *
 * 1111 1111 1111 1111 1111 1111 1100 1000 (the int)
 * &
 * 0000 0000 0000 0000 0000 0000 1111 1111 (the 0xFF)
 * =======================================
 * 0000 0000 0000 0000 0000 0000 1100 1000 (200)
 */
System.out.println(b & 0xFF); // "200"

/*
 * You would typically do this *within* the method that expected an 
 * unsigned byte and the advantage is you apply `0xFF` only once
 * and than you use the `unsignedByte` variable in all your bitwise
 * operations.
 *
 * You could use any integer type longer than `byte` for the `unsignedByte` variable,
 * i.e. `short`, `int`, `long` and even `char`, but during bitwise operations
 * it would get casted to `int` anyway.
 */
void printUnsignedByte(byte b) {
    int unsignedByte = b & 0xFF;
    System.out.println(unsignedByte); // "200"
}

Use display: block; margin: auto; it will center the div

For this, just needed simple lines not complicated

in your onBindViewHolder method add below code

final boolean isExpanded = position==mExpandedPosition;
holder.details.setVisibility(isExpanded?View.VISIBLE:View.GONE);
holder.itemView.setActivated(isExpanded);
holder.itemView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        mExpandedPosition = isExpanded ? -1:position;
        notifyItemChanged(position);
    }
});

mExpandedPosition is an int global variable initialized to -1

For those who want only one item expanded and others get collapsed. Use this

first declare a global variable with previousExpandedPosition = -1

then

    final boolean isExpanded = position==mExpandedPosition;
    holder.details.setVisibility(isExpanded?View.VISIBLE:View.GONE);
    holder.itemView.setActivated(isExpanded);

    if (isExpanded)
       previousExpandedPosition = position;

    holder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            mExpandedPosition = isExpanded ? -1:position;
            notifyItemChanged(previousExpandedPosition);
            notifyItemChanged(position);
        }
    });

Done!!!. Simple and humble .. :)

Assuming you have a form like this:

<form id="myForm" action="foo.php" method="post">
   <input type="text" value="" />
   <input type="submit" value="submit form" />

</form>

You can attach a onsubmit-event with jQuery like this:

$('#myForm').submit(function() {
  alert('Handler for .submit() called.');
  return false;
});

If you return false the form won't be submitted after the function, if you return true or nothing it will submit as usual.

See the jQuery documentation for more info.

The below code works for me, for both accessing and changing a pixel value.

For accessing pixel's channel value :

for (int i = 0; i < image.cols; i++) {
    for (int j = 0; j < image.rows; j++) {
        Vec3b intensity = image.at<Vec3b>(j, i);
        for(int k = 0; k < image.channels(); k++) {
            uchar col = intensity.val[k]; 
        }   
    }
}

For changing a pixel value of a channel :

uchar pixValue;
for (int i = 0; i < image.cols; i++) {
    for (int j = 0; j < image.rows; j++) {
        Vec3b &intensity = image.at<Vec3b>(j, i);
        for(int k = 0; k < image.channels(); k++) {
            // calculate pixValue
            intensity.val[k] = pixValue;
        }
     }
}

There is not. You will need to use some external library, or write your own parser. If you have the time to do so, I suggest to write your own parser as it is a quite interesting project. Otherwise you will need to use something like bcParser.

Look into python wheels to solve your problem. The best part of python wheels is that they let you install C extensions with no compilers. I just installed numpy and scipy using pip in a clean python install and they both worked fine.

The ioctl function is useful for implementing a device driver to set the configuration on the device. e.g. a printer that has configuration options to check and set the font family, font size etc. ioctl could be used to get the current font as well as set the font to a new one. A user application uses ioctl to send a code to a printer telling it to return the current font or to set the font to a new one.

int ioctl(int fd, int request, ...)

1. fd is file descriptor, the one returned by open;
2. request is request code. e.g GETFONT will get the current font from the printer, SETFONT will set the font on the printer;
3. the third argument is void *. Depending on the second argument, the third may or may not be present, e.g. if the second argument is SETFONT, the third argument can be the font name such as "Arial";

int request is not just a macro. A user application is required to generate a request code and the device driver module to determine which configuration on device must be played with. The application sends the request code using ioctl and then uses the request code in the device driver module to determine which action to perform.

A request code has 4 main parts

    1. A Magic number - 8 bits
    2. A sequence number - 8 bits
    3. Argument type (typically 14 bits), if any.
    4. Direction of data transfer (2 bits).  

If the request code is SETFONT to set font on a printer, the direction for data transfer will be from user application to device driver module (The user application sends the font name "Arial" to the printer). If the request code is GETFONT, direction is from printer to the user application.

In order to generate a request code, Linux provides some predefined function-like macros.

1._IO(MAGIC, SEQ_NO) both are 8 bits, 0 to 255, e.g. let us say we want to pause printer. This does not require a data transfer. So we would generate the request code as below

#define PRIN_MAGIC 'P'
#define NUM 0
#define PAUSE_PRIN __IO(PRIN_MAGIC, NUM) 

and now use ioctl as

ret_val = ioctl(fd, PAUSE_PRIN);

The corresponding system call in the driver module will receive the code and pause the printer.

2. __IOW(MAGIC, SEQ_NO, TYPE) MAGIC and SEQ_NO are the same as above, and TYPE gives the type of the next argument, recall the third argument of ioctl is void *. W in __IOW indicates that the data flow is from user application to driver module. As an example, suppose we want to set the printer font to "Arial".

#define PRIN_MAGIC 'S'
#define SEQ_NO 1
#define SETFONT __IOW(PRIN_MAGIC, SEQ_NO, unsigned long)

further,

char *font = "Arial";
ret_val = ioctl(fd, SETFONT, font); 

Now font is a pointer, which means it is an address best represented as unsigned long, hence the third part of _IOW mentions type as such. Also, this address of font is passed to corresponding system call implemented in device driver module as unsigned long and we need to cast it to proper type before using it. Kernel space can access user space and hence this works. other two function-like macros are __IOR(MAGIC, SEQ_NO, TYPE) and __IORW(MAGIC, SEQ_NO, TYPE) where the data flow will be from kernel space to user space and both ways respectively.

Please let me know if this helps!

If in .net ( I'm not sure if it works for all windows services)

• Stop the service (THis may be why you're having a problem.)
• InstallUtil -u [name of executable]
• Installutil -i [name of executable]
• Start the service again...

Unless I'm changing the service's public interface, I often deploy upgraded versions of my services without even unistalling/reinstalling... ALl I do is stop the service, replace the files and restart the service again...

If you check out the help of the unittest module it tells you about several combinations that allow you to run test case classes from a module and test methods from a test case class.

python3 -m unittest -h

[...]

Examples:
  python3 -m unittest test_module               - run tests from test_module
  python3 -m unittest module.TestClass          - run tests from module.TestClass
  python3 -m unittest module.Class.test_method  - run specified test method
```lang-none

It does not require you to define a `unittest.main()` as the default behaviour of your module.

I had the same issue. Root cause was using custom deserializer without default constructor.

Solved my issue like this with brute force.

I realised I hand multiple copies of the DLL all over the solution and two different versions.

Went into the solution in explorer, searched for the offending DLL and deleted all of them. Then added the references to the DLL back using the one version of the DLL.

we can use createNativeQuery("Here Nagitive SQL Query ");

for Example :

Query q = em.createNativeQuery("SELECT a.firstname, a.lastname FROM Author a");
List<Object[]> authors = q.getResultList();

You need to call the AddAddress method once for every recipient. Like so:

$mail->AddAddress('[email protected]', 'Person One');
$mail->AddAddress('[email protected]', 'Person Two');
// ..

Better yet, add them as Carbon Copy recipients.

$mail->AddCC('[email protected]', 'Person One');
$mail->AddCC('[email protected]', 'Person Two');
// ..

To make things easy, you should loop through an array to do this.

$recipients = array(
   '[email protected]' => 'Person One',
   '[email protected]' => 'Person Two',
   // ..
);
foreach($recipients as $email => $name)
{
   $mail->AddCC($email, $name);
}

How about using the unicode \u0026? Works for me in my android XML files. If problems arise, someone let me know.

Simple as that

The answer will vary slightly depending on whether the application or applet is using AWT or Swing.

(Basically, classes that start with J such as JApplet and JFrame are Swing, and Applet and Frame are AWT.)

In either case, the basic steps would be:

1. Draw or load an image into a Image object.
2. Draw the background image in the painting event of the Component you want to draw the background in.

Step 1. Loading the image can be either by using the Toolkit class or by the ImageIO class.

The Toolkit.createImage method can be used to load an Image from a location specified in a String:

Image img = Toolkit.getDefaultToolkit().createImage("background.jpg");

Similarly, ImageIO can be used:

Image img = ImageIO.read(new File("background.jpg");

Step 2. The painting method for the Component that should get the background will need to be overridden and paint the Image onto the component.

For AWT, the method to override is the paint method, and use the drawImage method of the Graphics object that is handed into the paint method:

public void paint(Graphics g)
{
    // Draw the previously loaded image to Component.
    g.drawImage(img, 0, 0, null);

    // Draw sprites, and other things.
    // ....
}

For Swing, the method to override is the paintComponent method of the JComponent, and draw the Image as with what was done in AWT.

public void paintComponent(Graphics g)
{
    // Draw the previously loaded image to Component.
    g.drawImage(img, 0, 0, null);

    // Draw sprites, and other things.
    // ....
}

Simple Component Example

Here's a Panel which loads an image file when instantiated, and draws that image on itself:

class BackgroundPanel extends Panel
{
    // The Image to store the background image in.
    Image img;
    public BackgroundPanel()
    {
        // Loads the background image and stores in img object.
        img = Toolkit.getDefaultToolkit().createImage("background.jpg");
    }

    public void paint(Graphics g)
    {
        // Draws the img to the BackgroundPanel.
        g.drawImage(img, 0, 0, null);
    }
}

use grep -n -i null myfile.txt to output the line number in front of each match.

I dont think grep has a switch to print the count of total lines matched, but you can just pipe grep's output into wc to accomplish that:

grep -n -i null myfile.txt | wc -l

I guess your code relates to Windows Forms.
You call BeginInvoke if you need something to be executed asynchronously in the UI thread: change control's properties in most of the cases.
Roughly speaking this is accomplished be passing the delegate to some procedure which is being periodically executed. (message loop processing and the stuff like that)

If BeginInvoke is called for Delegate type the delegate is just invoked asynchronously.
(Invoke for the sync version.)

If you want more universal code which works perfectly for WPF and WinForms you can consider Task Parallel Library and running the Task with the according context. (TaskScheduler.FromCurrentSynchronizationContext())

And to add a little to already said by others: Lambdas can be treated either as anonymous methods or expressions.
And that is why you cannot just use var with lambdas: compiler needs a hint.

UPDATE:

this requires .Net v4.0 and higher

// This line must be called in UI thread to get correct scheduler
var scheduler = System.Threading.Tasks.TaskScheduler.FromCurrentSynchronizationContext();

// this can be called anywhere
var task = new System.Threading.Tasks.Task( () => someformobj.listBox1.SelectedIndex = 0);

// also can be called anywhere. Task  will be scheduled for execution.
// And *IF I'm not mistaken* can be (or even will be executed synchronously)
// if this call is made from GUI thread. (to be checked) 
task.Start(scheduler);

If you started the task from other thread and need to wait for its completition task.Wait() will block calling thread till the end of the task.

Read more about tasks here.

1. Open the command prompt - start → Run → cmd, or start menu → All Programs → Accessories → Command Prompt.

2. Type

   netstat -aon | findstr '[port_number]'
   

Replace the [port_number] with the actual port number that you want to check and hit Enter.

3. If the port is being used by any application, then that application’s detail will be shown. The number, which is shown at the last column of the list, is the PID (process ID) of that application. Make note of this.

4. Type

   tasklist | findstr '[PID]'
   

Replace the [PID] with the number from the above step and hit Enter.

5. You’ll be shown the application name that is using your port number.

Please add the correct mime-types to your code - at least these ones:

.jpeg -> image/jpeg
.gif  -> image/gif
.png  -> image/png

A list of mime-types can be found here.

Furthermore, simplify the code's logic and report an error number to help the first level support track down problems:

$allowedExts = array(
  "pdf", 
  "doc", 
  "docx"
); 

$allowedMimeTypes = array( 
  'application/msword',
  'text/pdf',
  'image/gif',
  'image/jpeg',
  'image/png'
);

$extension = end(explode(".", $_FILES["file"]["name"]));

if ( 20000 < $_FILES["file"]["size"]  ) {
  die( 'Please provide a smaller file [E/1].' );
}

if ( ! ( in_array($extension, $allowedExts ) ) ) {
  die('Please provide another file type [E/2].');
}

if ( in_array( $_FILES["file"]["type"], $allowedMimeTypes ) ) 
{      
 move_uploaded_file($_FILES["file"]["tmp_name"], "upload/" . $_FILES["file"]["name"]); 
}
else
{
die('Please provide another file type [E/3].');
}

To add to Lennart Regebro's answer There is even the third way that can be used:

encoded3 = str.encode(original, 'utf-8')
print(encoded3)

Anyway, it is actually exactly the same as the first approach. It may also look that the second way is a syntactic sugar for the third approach.

A programming language is a means to express abstract ideas formally, to be executed by the machine. A programming language is considered good if it contains constructs that one needs. Python is a hybrid language -- i.e. more natural and more versatile than pure OO or pure procedural languages. Sometimes functions are more appropriate than the object methods, sometimes the reverse is true. It depends on mental picture of the solved problem.

Anyway, the feature mentioned in the question is probably a by-product of the language implementation/design. In my opinion, this is a nice example that show the alternative thinking about technically the same thing.

In other words, calling an object method means thinking in terms "let the object gives me the wanted result". Calling a function as the alternative means "let the outer code processes the passed argument and extracts the wanted value".

The first approach emphasizes the ability of the object to do the task on its own, the second approach emphasizes the ability of an separate algoritm to extract the data. Sometimes, the separate code may be that much special that it is not wise to add it as a general method to the class of the object.

range(x) returns a list of numbers from 0 to x - 1.

>>> range(1)
[0]
>>> range(2)
[0, 1]
>>> range(3)
[0, 1, 2]
>>> range(4)
[0, 1, 2, 3]

for i in range(x): executes the body (which is print i in your first example) once for each element in the list returned by range(). i is used inside the body to refer to the “current” item of the list. In that case, i refers to an integer, but it could be of any type, depending on the objet on which you loop.

java.time.Duration

I still didn’t feel any of the answers was quite up to date and to the point. So here is the modern answer using Duration from java.time, the modern Java date and time API (the answers by MayurB and mkobit mention the same class, but none of them correctly converts to days, hours, minutes and minutes as asked).

    DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yy/MM/dd HH:mm:ss");
    
    String dateStart = "11/03/14 09:29:58";
    String dateStop = "11/03/14 09:33:43";

    ZoneId zone = ZoneId.systemDefault();
    ZonedDateTime startDateTime = LocalDateTime.parse(dateStart, formatter).atZone(zone);
    ZonedDateTime endDateTime = LocalDateTime.parse(dateStop, formatter).atZone(zone);
    
    Duration diff = Duration.between(startDateTime, endDateTime);
    if (diff.isZero()) {
        System.out.println("0 minutes");
    } else {
        long days = diff.toDays();
        if (days != 0) {
            System.out.print("" + days + " days ");
            diff = diff.minusDays(days);
        }
        long hours = diff.toHours();
        if (hours != 0) {
            System.out.print("" + hours + " hours ");
            diff = diff.minusHours(hours);
        }
        long minutes = diff.toMinutes();
        if (minutes != 0) {
            System.out.print("" + minutes + " minutes ");
            diff = diff.minusMinutes(minutes);
        }
        long seconds = diff.getSeconds();
        if (seconds != 0) {
            System.out.print("" + seconds + " seconds ");
        }
        System.out.println();
    }

Output from this example snippet is:

3 minutes 45 seconds

Note that Duration always counts a day as 24 hours. If you want to treat time anomalies like summer time transistions differently, solutions inlcude (1) use ChronoUnit.DAYS (2) Use Period (3) Use LocalDateTimeinstead ofZonedDateTime` (may be considered a hack).

The code above works with Java 8 and with ThreeTen Backport, that backport of java.time to Java 6 and 7. From Java 9 it may be possible to write it a bit more nicely using the methods toHoursPart, toMinutesPart and toSecondsPart added there.

I will elaborate the explanations further one of the days when I get time, maybe not until next week.

Hope you have key field is two tables.

 UPDATE tblindiantime t
   SET CountryName = (SELECT c.BusinessCountry 
                     FROM contacts c WHERE c.Key = t.Key 
                     )

From the Maven Embedder documentation:

-fae,--fail-at-end Only fail the build afterwards; allow all non-impacted builds to continue

-fn,--fail-never NEVER fail the build, regardless of project result

So if you are testing one module than you are safe using -fae.

Otherwise, if you have multiple modules, and if you want all of them tested (even the ones that depend on the failing tests module), you should run mvn clean install -fn.
-fae will continue with the module that has a failing test (will run all other tests), but all modules that depend on it will be skipped.

Change

$info=$_POST['id[]'];

to

$info=$_POST['id'];

by adding [] to the end of your form field names, PHP will automatically convert these variables into arrays.

The primitive wrapper types are reference types that are automatically created behind the scenes whenever strings, num­bers, or Booleans are read.For example :

var name = "foo";
var firstChar = name.charAt(0);
console.log(firstChar);

This is what happens behind the scenes:

// what the JavaScript engine does
var name = "foo";
var temp = new String(name);
var firstChar = temp.charAt(0);
temp = null;
console.log(firstChar);

Because the second line uses a string (a primitive) like an object, the JavaScript engine creates an instance of String so that charAt(0) will work.The String object exists only for one statement before it’s destroyed check this

The instanceof operator returns false because a temporary object is created only when a value is read. Because instanceof doesn’t actually read anything, no temporary objects are created, and it tells us the ­values aren’t instances of primitive wrapper types. You can create primitive wrapper types manually

There are great responses here. I would like to keep it short to memorize the difference between partition & buckets.

You generally partition on a less unique column. And bucketing on most unique column.

Example if you consider World population with country, person name and their bio-metric id as an example. As you can guess, country field would be the less unique column and bio-metric id would be the most unique column. So ideally you would need to partition the table by country and bucket it by bio-metric id.

Try This, change

$config['base_url'] = 'http://mywebsite.cl/';

to

$config['base_url'] = 'http://www.mywebsite.cl/';

Some provider auto add www , https , etc to your url, most of the times, this causes this issue

There is a ToArray() function on Values:

Foo[] arr = new Foo[dict.Count];    
dict.Values.CopyTo(arr, 0);

But I don't think its efficient (I haven't really tried, but I guess it copies all these values to the array). Do you really need an Array? If not, I would try to pass IEnumerable:

IEnumerable<Foo> foos = dict.Values;

Another way to navigate to the location of a function definition would be to break in debugger somewhere you can access the function and enter the functions fully qualified name in the console. This will print the function definition in the console and give a link which on click opens the script location where the function is defined.

SimpleDateFormat.format() method takes a Date as a parameter. You can get a Date from a Calendar by calling its getTime() method:

public static String format(GregorianCalendar calendar) {
    SimpleDateFormat fmt = new SimpleDateFormat("dd-MMM-yyyy");
    fmt.setCalendar(calendar);
    String dateFormatted = fmt.format(calendar.getTime());

    return dateFormatted;
}

Also note that the months start at 0, so you probably meant:

int month = Integer.parseInt(splitDate[1]) - 1;

I know this question is quite old, but I found another way of initializing, using constexpr and currying:

struct mp_struct_t {
    public:
        constexpr mp_struct_t(int member1) : mp_struct_t(member1, 0, 0) {}
        constexpr mp_struct_t(int member1, int member2, int member3) : member1(member1), member2(member2), member3(member3) {}
        constexpr mp_struct_t another_member(int member) { return {member1, member,     member2}; }
        constexpr mp_struct_t yet_another_one(int member) { return {member1, member2, member}; }

    int member1, member2, member3;
};

static mp_struct_t a_struct = mp_struct_t{1}
                           .another_member(2)
                           .yet_another_one(3);

This method also works for global static variables and even constexpr ones. The only disadvantage is the bad maintainability: Everytime another member has to be made initializable using this method, all member initialization methods have to be changed.

Lazy simple version for forgetfuls like me:

git rebase -i HEAD~3 or however many commits instead of 3.

Turn this

pick YourCommitMessageWhatever
pick YouGetThePoint
pick IdkManItsACommitMessage

into this

pick YourCommitMessageWhatever
s YouGetThePoint
s IdkManItsACommitMessage

and do some action where you hit esc then enter to save the changes. [1]

When the next screen comes up, get rid of those garbage # lines [2] and create a new commit message or something, and do the same escape enter action. [1]

Wowee, you have fewer commits. Or you just broke everything.

[1] - or whatever works with your git configuration. This is just a sequence that's efficient given my setup.

[2] - you'll see some stuff like # this is your n'th commit a few times, with your original commits right below these message. You want to remove these lines, and create a commit message to reflect the intentions of the n commits that you're combining into 1.

Hopefully this can help others: The above examples use ax.lines. With more recent mpl (3.3.1), there is ax.get_lines(). This bypasses the need for calling ax.lines=[]

for line in ax.get_lines(): # ax.lines:
    line.remove()
# ax.lines=[] # needed to complete removal when using ax.lines

Just go to Google Fonts - http://www.google.com/fonts/ , add the font you like to your collection, and press the download button. And then just use the @fontface to connect this font to your web page. Btw, if you open the link you are using, you'll see an example of using @fontface

http://fonts.googleapis.com/css?family=Open+Sans:400italic,600italic,400,600,300

For an example

@font-face {
  font-family: 'Open Sans';
  font-style: normal;
  font-weight: 300;
  src: local('Open Sans Light'), local('OpenSans-Light'), url(http://themes.googleusercontent.com/static/fonts/opensans/v6/DXI1ORHCpsQm3Vp6mXoaTaRDOzjiPcYnFooOUGCOsRk.woff) format('woff');
}

Just change the url address to the local link on the font file, you've downloaded.

You can do it even easier.

Just download the file, you've linked:

http://fonts.googleapis.com/css?family=Open+Sans:400italic,600italic,400,600,300

Name it opensans.css or so.

Then just change the links in url() to your path to font files.

And then replace your example string with:

<link href='opensans.css' rel='stylesheet' type='text/css'>

I would answer with slight modification with aforementioned answers and that is to write a prettified JSON file which human eyes can read better. For this, pass sort_keys as True and indent with 4 space characters and you are good to go. Also take care of ensuring that the ascii codes will not be written in your JSON file:

with open('data.txt', 'w') as outfile:
     json.dump(jsonData, outfile, sort_keys = True, indent = 4,
               ensure_ascii = False)

On Ubuntu, for versions of Sublime older than 3.2, what worked for me was changing the dpi scale in Preferences > Settings — User by adding this line:

"dpi_scale": 1.10 

For Sublime 3.2, you can use the following line instead:

"ui_scale": 1.10

Adjust the scale value as needed. After this change, you have to restart Sublime Text for it to take effect.

Save your file with different encoding:

File > Save file as... > Save as UTF-8 without signature.

In VS 2017 you find encoding as a dropdown next to Save button.

$('#selectorID').val();

OR

$('select[name=selector]').val();

OR

$('.class_nam').val();

If it doesn't matter the order of the elements. you can swap between the elements foo[x] and foo[0], then call foo.drop(1).

foo.drop(n) removes (n) first elements from the array.

I guess this is the simplest and resource efficient way to do.

PS: indexOf can be implemented in many ways, this is my version.

Integer indexOf(String[] arr, String value){
    for(Integer i = 0 ; i < arr.length; i++ )
        if(arr[i] == value)
            return i;         // return the index of the element
    return -1                 // otherwise -1
}

while (true) {
   Integer i;
   i = indexOf(foo,"a")
   if (i == -1) break;
   foo[i] = foo[0];           // preserve foo[0]
   foo.drop(1);
}

This is a way to see if any XML-files exists in that folder, yes.

To check for specific files use File.Exists(path), which will return a boolean indicating wheter the file at path exists.

In the very most simple case of no collisions

• with rebase: rebases your local commits ontop of remote HEAD and does not create a merge/merge commit
• without/normal: merges and creates a merge commit

See also:

man git-pull

More precisely, git pull runs git fetch with the given parameters and calls git merge to merge the retrieved branch heads into the current branch. With --rebase, it runs git rebase instead of git merge.

On a higher level:

1) Async keyword enables the await and that's all it does. Async keyword does not run the method in a separate thread. The beginning f async method runs synchronously until it hits await on a time-consuming task.

2) You can await on a method that returns Task or Task of type T. You cannot await on async void method.

3) The moment main thread encounters await on time-consuming task or when the actual work is started, the main thread returns to the caller of the current method.

4) If the main thread sees await on a task that is still executing, it doesn't wait for it and returns to the caller of the current method. In this way, the application remains responsive.

5) Await on processing task, will now execute on a separate thread from the thread pool.

6) When this await task is completed, all the code below it will be executed by the separate thread

Below is the sample code. Execute it and check the thread id

using System;
using System.Threading;
using System.Threading.Tasks;

namespace AsyncAwaitDemo
{
    class Program
    {
        public static async void AsynchronousOperation()
        {
            Console.WriteLine("Inside AsynchronousOperation Before AsyncMethod, Thread Id: " + Thread.CurrentThread.ManagedThreadId);
            //Task<int> _task = AsyncMethod();
            int count = await AsyncMethod();

            Console.WriteLine("Inside AsynchronousOperation After AsyncMethod Before Await, Thread Id: " + Thread.CurrentThread.ManagedThreadId);

            //int count = await _task;

            Console.WriteLine("Inside AsynchronousOperation After AsyncMethod After Await Before DependentMethod, Thread Id: " + Thread.CurrentThread.ManagedThreadId);

            DependentMethod(count);

            Console.WriteLine("Inside AsynchronousOperation After AsyncMethod After Await After DependentMethod, Thread Id: " + Thread.CurrentThread.ManagedThreadId);
        }

        public static async Task<int> AsyncMethod()
        {
            Console.WriteLine("Inside AsyncMethod, Thread Id: " + Thread.CurrentThread.ManagedThreadId);
            int count = 0;

            await Task.Run(() =>
            {
                Console.WriteLine("Executing a long running task which takes 10 seconds to complete, Thread Id: " + Thread.CurrentThread.ManagedThreadId);
                Thread.Sleep(20000);
                count = 10;
            });

            Console.WriteLine("Completed AsyncMethod, Thread Id: " + Thread.CurrentThread.ManagedThreadId);

            return count;
        }       

        public static void DependentMethod(int count)
        {
            Console.WriteLine("Inside DependentMethod, Thread Id: " + Thread.CurrentThread.ManagedThreadId + ". Total count is " + count);
        }

        static void Main(string[] args)
        {
            Console.WriteLine("Started Main method, Thread Id: " + Thread.CurrentThread.ManagedThreadId);

            AsynchronousOperation();

            Console.WriteLine("Completed Main method, Thread Id: " + Thread.CurrentThread.ManagedThreadId);

            Console.ReadKey();
        }

    }
}

It is possible to use a handler to do this, even in MVC4. Here's an example from one i made earlier:

public class ImageHandler : IHttpHandler
{
    byte[] bytes;

    public void ProcessRequest(HttpContext context)

Mp4 files can be playable with transparent background using seeThrou Js library. All you need to combine actual video and alpha channel in the single video. Also make sure to keep video height dimension below 1400 px as some of the old iphone devices wont play videos with dimension more than 2000. This is pretty useful in safari desktop and mobile devices which doesnt support webm at this time.

more details can be found in the below link https://github.com/m90/seeThru

EDIT: added a new example for ggplot2 at the end

See ?plotmath for the different mathematical operations in R

You should be able to use expression without paste. If you use the tilda (~) symbol within the expression function it will assume there is a space between the characters, or you could use the * symbol and it won't put a space between the arguments

Sometimes you will need to change the margins in you're putting superscripts on the y-axis.

par(mar=c(5, 4.3, 4, 2) + 0.1)
plot(1:10, xlab = expression(xLab ~ x^2 ~ m^-2),
     ylab = expression(yLab ~ y^2 ~ m^-2),
     main="Plot 1")

plot(1:10, xlab = expression(xLab * x^2 * m^-2),
     ylab = expression(yLab * y^2 * m^-2),
     main="Plot 2")

plot(1:10, xlab = expression(xLab ~ x^2 * m^-2),
     ylab = expression(yLab ~ y^2 * m^-2),
     main="Plot 3")

Hopefully you can see the differences between plots 1, 2 and 3 with the different uses of the ~ and * symbols. An extra note, you can use other symbols such as plotting the degree symbol for temperatures for or mu, phi. If you want to add a subscript use the square brackets.

plot(1:10, xlab = expression('Your x label' ~ mu[3] * phi),
     ylab = expression("Temperature (" * degree * C *")"))

Here is a ggplot example using expression with a nonsense example

require(ggplot2)

Or if you have the pacman library installed you can use p_load to automatically download and load and attach add-on packages

# require(pacman)
# p_load(ggplot2)

data = data.frame(x = 1:10, y = 1:10)

ggplot(data, aes(x,y)) + geom_point() + 
  xlab(expression(bar(yourUnits) ~ g ~ m^-2 ~ OR ~ integral(f(x)*dx, a,b))) + 
  ylab(expression("Biomass (g per" ~ m^3 *")")) + theme_bw()

Simply app.use means “Run this on ALL requests”
app.get means “Run this on a GET request, for the given URL”

Typically, you can copy the .classpath file from a working project since there isn’t anything project specific here assuming you’re structured as a standard Maven project.

This question has been already answered in Unicode characters in Windows command line - how?

You missed one step -> you need to use Lucida console fonts in addition to executing chcp 65001 from cmd console.

Your format specifier is incorrect. From the printf() man page on my machine:

0 A zero '0' character indicating that zero-padding should be used rather than blank-padding. A '-' overrides a '0' if both are used;

Field Width: An optional digit string specifying a field width; if the output string has fewer characters than the field width it will be blank-padded on the left (or right, if the left-adjustment indicator has been given) to make up the field width (note that a leading zero is a flag, but an embedded zero is part of a field width);

Precision: An optional period, '.', followed by an optional digit string giving a precision which specifies the number of digits to appear after the decimal point, for e and f formats, or the maximum number of characters to be printed from a string; if the digit string is missing, the precision is treated as zero;

For your case, your format would be %09.3f:

#include <stdio.h>

int main(int argc, char **argv)
{
  printf("%09.3f\n", 4917.24);
  return 0;
}

Output:

$ make testapp
cc     testapp.c   -o testapp
$ ./testapp 
04917.240

Note that this answer is conditional on your embedded system having a printf() implementation that is standard-compliant for these details - many embedded environments do not have such an implementation.

You have to make one ajax call to get the required result, in this case you can use Google API to get the same

http://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&sensor=true/false

Build this kind of url and replace the lat long with the one you want to. do the call and response will be in JSON, parse the JSON and you will get the complete address up to street level

I think the answer located in this article: https://arjunphp.com/laravel-5-5-log-eloquent-queries/

is fast and simple to achieve query logging.

You just have to add to the AppServiceProvider in the boot method a callback to listen to DB queries:

namespace App\Providers;

use DB;
use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    public function boot()
    {
        DB::listen(function($query) {
            logger()->info($query->sql . print_r($query->bindings, true));
        });
    }
}

Or if you just want to redefine the behavior of the console (in order to add logs for example) You can do something like that:

// define a new console
var console=(function(oldCons){
    return {
        log: function(text){
            oldCons.log(text);
            // Your code
        },
        info: function (text) {
            oldCons.info(text);
            // Your code
        },
        warn: function (text) {
            oldCons.warn(text);
            // Your code
        },
        error: function (text) {
            oldCons.error(text);
            // Your code
        }
    };
}(window.console));

//Then redefine the old console
window.console = console;

How to delete SQLite database from Android programmatically

DELETE

The DELETE command is used to remove rows from a table. A WHERE clause can be used to only remove some rows. If no WHERE condition is specified, all rows will be removed. After performing a DELETE operation you need to COMMIT or ROLLBACK the transaction to make the change permanent or to undo it. Note that this operation will cause all DELETE triggers on the table to fire.

TRUNCATE

TRUNCATE removes all rows from a table. The operation cannot be rolled back and no triggers will be fired. As such, TRUCATE is faster and doesn't use as much undo space as a DELETE.

DROP

The DROP command removes a table from the database. All the tables' rows, indexes and privileges will also be removed. No DML triggers will be fired. The operation cannot be rolled back.

---

DROP and TRUNCATE are DDL commands, whereas DELETE is a DML command. Therefore DELETE operations can be rolled back (undone), while DROP and TRUNCATE operations cannot be rolled back.

This limitation of the standard shutil.copytree seems arbitrary and annoying. Workaround:

import os, shutil
def copytree(src, dst, symlinks=False, ignore=None):
    for item in os.listdir(src):
        s = os.path.join(src, item)
        d = os.path.join(dst, item)
        if os.path.isdir(s):
            shutil.copytree(s, d, symlinks, ignore)
        else:
            shutil.copy2(s, d)

Note that it's not entirely consistent with the standard copytree:

• it doesn't honor symlinks and ignore parameters for the root directory of the src tree;
• it doesn't raise shutil.Error for errors at the root level of src;
• in case of errors during copying of a subtree, it will raise shutil.Error for that subtree instead of trying to copy other subtrees and raising single combined shutil.Error.

There's a simple command built-in that will pull it:

rvm implode

This will remove the rvm/ directory and all the rubies built within it. In order to remove the final trace of rvm, you need to remove the rvm gem, too:

gem uninstall rvm

If you've made modifications to your PATH you might want to pull those, too. Check your .bashrc, .profile and .bash_profile files, among other things.

You may also have an /etc/rvmrc file, or one in your home directory ~/.rvmrc that may need to be removed as well.

Assuming you mean for a debugging session(?) then you can include a env property in your launch configuration.

If you open the .vscode/launch.json file in your workspace or select Debug > Open Configurations then you should see a set of launch configurations for debugging your code. You can then add to it an env property with a dictionary of string:string.

Here is an example for an ASP.NET Core app from their standard web template setting the ASPNETCORE_ENVIRONMENT to Development :

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": ".NET Core Launch (web)",
      "type": "coreclr",
      "request": "launch",
      "preLaunchTask": "build",
      // If you have changed target frameworks, make sure to update the program path.
      "program": "${workspaceFolder}/bin/Debug/netcoreapp2.0/vscode-env.dll",
      "args": [],
      "cwd": "${workspaceFolder}",
      "stopAtEntry": false,
      "internalConsoleOptions": "openOnSessionStart",
      "launchBrowser": {
        "enabled": true,
        "args": "${auto-detect-url}",
        "windows": {
          "command": "cmd.exe",
          "args": "/C start ${auto-detect-url}"
        },
        "osx": {
          "command": "open"
        },
        "linux": {
          "command": "xdg-open"
        }
      },
      "env": {
        "ASPNETCORE_ENVIRONMENT": "Development"
      },
      "sourceFileMap": {
        "/Views": "${workspaceFolder}/Views"
      }
    },
    {
      "name": ".NET Core Attach",
      "type": "coreclr",
      "request": "attach",
      "processId": "${command:pickProcess}"
    }
  ]
}

The general syntax, as depicted already is:

std::vector<std::vector<int> > v (A_NUMBER, std::vector <int> (OTHER_NUMBER, DEFAULT_VALUE))  

Here, the vector 'v' can be visualised as a two dimensional array, with 'A_NUMBER' of rows, with 'OTHER_NUMBER' of columns with their initial value set to 'DEFAULT_VALUE'.

Also it can be written like this:

std::vector <int> line(OTHER_NUMBER, DEFAULT_VALUE)
std::vector<std::vector<int> > v(A_NUMBER, line)

Inputting values in a 2-D vector is similar to inputting values in a 2-D array:

for(int i = 0; i < A_NUMBER; i++) {
     for(int j = 0; j < OTHER_NUMBER; j++) {
         std::cin >> v[i][j]
     }
}

Examples have already been stated in other answers....!

When displaying I sometimes make a new file called Funk. This will have the font, size etc. This is the code for the class:

import pygame

def text_to_screen(screen, text, x, y, size = 50,
            color = (200, 000, 000), font_type = 'data/fonts/orecrusherexpand.ttf'):
    try:

        text = str(text)
        font = pygame.font.Font(font_type, size)
        text = font.render(text, True, color)
        screen.blit(text, (x, y))

    except Exception, e:
        print 'Font Error, saw it coming'
        raise e

Then when that has been imported when I want to display text taht updates E.G score I do:

Funk.text_to_screen(screen, 'Text {0}'.format(score), xpos, ypos)

If it is just normal text that isn't being updated:

Funk.text_to_screen(screen, 'Text', xpos, ypos)

You may notice {0} on the first example. That is because when .format(whatever) is used that is what will be updated. If you have something like Score then target score you'd do {0} for score then {1} for target score then .format(score, targetscore)

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

None/Null is a data type of the class NoneType in pyspark/python so, Below will not work as you are trying to compare NoneType object with string object

df[df.dt_mvmt == None].count() 0 df[df.dt_mvmt != None].count() 0

correct

df=df.where(col("dt_mvmt").isNotNull()) returns all records with dt_mvmt as None/Null

Exploiting the fact that Number.MAX_VALUE < 171!, we can simply use a complete lookup table consisting of just 171 compact array elements taking up less than 1.4 kilobytes of memory.

A fast lookup function with runtime complexity O(1) and minimal array access overhead would then look as follows:

// Lookup table for n! for 0 <= n <= 170:_x000D_
const factorials = [1,1,2,6,24,120,720,5040,40320,362880,3628800,39916800,479001600,6227020800,87178291200,1307674368e3,20922789888e3,355687428096e3,6402373705728e3,121645100408832e3,243290200817664e4,5109094217170944e4,1.1240007277776077e21,2.585201673888498e22,6.204484017332394e23,1.5511210043330986e25,4.0329146112660565e26,1.0888869450418352e28,3.0488834461171387e29,8.841761993739702e30,2.6525285981219107e32,8.222838654177922e33,2.631308369336935e35,8.683317618811886e36,2.9523279903960416e38,1.0333147966386145e40,3.7199332678990125e41,1.3763753091226346e43,5.230226174666011e44,2.0397882081197444e46,8.159152832478977e47,3.345252661316381e49,1.40500611775288e51,6.041526306337383e52,2.658271574788449e54,1.1962222086548019e56,5.502622159812089e57,2.5862324151116818e59,1.2413915592536073e61,6.082818640342675e62,3.0414093201713376e64,1.5511187532873822e66,8.065817517094388e67,4.2748832840600255e69,2.308436973392414e71,1.2696403353658276e73,7.109985878048635e74,4.0526919504877214e76,2.3505613312828785e78,1.3868311854568984e80,8.32098711274139e81,5.075802138772248e83,3.146997326038794e85,1.98260831540444e87,1.2688693218588417e89,8.247650592082472e90,5.443449390774431e92,3.647111091818868e94,2.4800355424368305e96,1.711224524281413e98,1.1978571669969892e100,8.504785885678623e101,6.1234458376886085e103,4.4701154615126844e105,3.307885441519386e107,2.48091408113954e109,1.8854947016660504e111,1.4518309202828587e113,1.1324281178206297e115,8.946182130782976e116,7.156945704626381e118,5.797126020747368e120,4.753643337012842e122,3.945523969720659e124,3.314240134565353e126,2.81710411438055e128,2.4227095383672734e130,2.107757298379528e132,1.8548264225739844e134,1.650795516090846e136,1.4857159644817615e138,1.352001527678403e140,1.2438414054641308e142,1.1567725070816416e144,1.087366156656743e146,1.032997848823906e148,9.916779348709496e149,9.619275968248212e151,9.426890448883248e153,9.332621544394415e155,9.332621544394415e157,9.42594775983836e159,9.614466715035127e161,9.90290071648618e163,1.0299016745145628e166,1.081396758240291e168,1.1462805637347084e170,1.226520203196138e172,1.324641819451829e174,1.4438595832024937e176,1.588245541522743e178,1.7629525510902446e180,1.974506857221074e182,2.2311927486598138e184,2.5435597334721877e186,2.925093693493016e188,3.393108684451898e190,3.969937160808721e192,4.684525849754291e194,5.574585761207606e196,6.689502913449127e198,8.094298525273444e200,9.875044200833601e202,1.214630436702533e205,1.506141741511141e207,1.882677176888926e209,2.372173242880047e211,3.0126600184576594e213,3.856204823625804e215,4.974504222477287e217,6.466855489220474e219,8.47158069087882e221,1.1182486511960043e224,1.4872707060906857e226,1.9929427461615188e228,2.6904727073180504e230,3.659042881952549e232,5.012888748274992e234,6.917786472619489e236,9.615723196941089e238,1.3462012475717526e241,1.898143759076171e243,2.695364137888163e245,3.854370717180073e247,5.5502938327393044e249,8.047926057471992e251,1.1749972043909107e254,1.727245890454639e256,2.5563239178728654e258,3.80892263763057e260,5.713383956445855e262,8.62720977423324e264,1.3113358856834524e267,2.0063439050956823e269,3.0897696138473508e271,4.789142901463394e273,7.471062926282894e275,1.1729568794264145e278,1.853271869493735e280,2.9467022724950384e282,4.7147236359920616e284,7.590705053947219e286,1.2296942187394494e289,2.0044015765453026e291,3.287218585534296e293,5.423910666131589e295,9.003691705778438e297,1.503616514864999e300,2.5260757449731984e302,4.269068009004705e304,7.257415615307999e306];_x000D_

console.log(factorial(Infinity));  // Infinity

This is as precise and as fast as it gets using the Number datatype. Computing the lookup table in Javascript - as some other answers suggest - will reduce precision when n! > Number.MAX_SAFE_INTEGER.

Compressing the runtime table via gzip reduces its size on disk from about 3.6 to 1.8 kilobytes.

There should be no semicolon here:

class WordGame;

...but there should be one at the end of your class definition:

...
private:
    string theWord;
}; // <-- Semicolon should be at the end of your class definition

Except that it will not work if your user name and database name are differents. It sounds like an SQLDeveloper bug and i can't find any workaroud

Maybe there are some bugs in Oracle SQL Developer when it connect to the postgresql.However I connect postgresql with navicat successfully.(My postgresql username and database name are different

Smallest and simplest solution (in single line) is:

$ file=/blaabla/bla/blah/foo.txt
echo $(basename ${file%.*}) # foo

Best Solution

The only difference is

1.Mutex -> lock and unlock are under the ownership of a thread that locks the mutex.

2.Semaphore -> No ownership i.e; if one thread calls semwait(s) any other thread can call sempost(s) to remove the lock.

I usually use

$(this).css({
    "textAlign":"center",
    "secondCSSProperty":"value" 
});

Hope that helps

Surround your %1 with something.

Eg:

if not "%1" == ""

Another one I've seen fairly often:

if not {%1} == {}

And so on...

The problem, as you can likely guess, is that the %1 is literally replaced with emptiness. It is not 'an empty string' it is actually a blank spot in your source file at that point.

Then after the replacement, the interpreter tries to parse the if statement and gets confused.

Just a note to the answer done by James Sulak.

If you want to take into consideration that the node may not exist and want to keep it purely XPATH, then try the following that will return 0 if the node does not exist.

count(a/b[.='tsr']/preceding-sibling::*)+number(boolean(a/b[.='tsr']))

Try with this JSFiddle DEMO : http://jsfiddle.net/2yEtK/3/

Jquery Code:

$("a.removeRecord").live("click",function(event){
   event.stopPropagation();
   if(confirm("Do you want to delete?")) {
    this.click;
       alert("Ok");
   }
   else
   {
       alert("Cancel");
   }       
   event.preventDefault();

});

If you git stash pop (with no conflicts) it will remove the stash after it is applied. But if you git stash apply it will apply the patch without removing it from the stash list. Then you can revert the unwanted changes with git checkout -- files...

In my case, I created a new ChildComponent in Parentcomponent whereas both in the same module but Parent is registered in a shared module so I created ChildComponent using CLI which registered Child in the current module but my parent was registered in the shared module.

So register the ChildComponent in Shared Module manually.

       String s="0000000000046457657772752256266542=56256010000085100000";      
    String removeString="";

    for(int i =0;i<s.length();i++){
      if(s.charAt(i)=='0')
        removeString=removeString+"0";
      else 
        break;
    }

    System.out.println("original string - "+s);

    System.out.println("after removing 0's -"+s.replaceFirst(removeString,""));

you can use .NET's built in method to remove the QueryString. i.e., Request.QueryString.Remove["whatever"];

here whatever in the [ ] is name of the querystring which you want to remove.

Try this... I hope this will help.

I found to be the best practice of using images, videos, etc. is:

• Change your files "Build action" to "Content". Be sure to check Copy to build directory.
  • Found on the "Right-Click" menu at the Solution Explorer window.
• Image Source in the following format:
  • "/«YourAssemblyName»;component/«YourPath»/«YourImage.png»"

Example

<Image Source="/WPFApplication;component/Images/Start.png" />

Benefits:

• Files are not embedded into the assembly.
  • The Resource Manager will raise some memory overflow problems with too many resources (at build time).
• Can be called between assemblies.

A better solution is not to make your page dependable on zoom settings. If you set limits like the one you are proposing, you are limiting accessibility. If someone cannot read your text well, they just won't be able to change that. I would use proper CSS to make it look nice in any zoom.

If your really insist, take a look at this question on how to detect zoom level using JavaScript (nightmare!): How to detect page zoom level in all modern browsers?

No. The only you can do is to add content (and not an element) using :before or :after pseudo-element.

If the library is static, then at link time the code is linked in with your executable. This makes your executable larger (than if you went the dynamic route).

If the library is dynamic then at link time references to the required methods are built in to your executable. This means that you have to ship your executable and the dynamic library. You also ought to consider whether shared access to the code in the library is safe, preferred load address among other stuff.

If you can live with the static library, go with the static library.

Put this code in a static class> public static class ClassName{ }

public static DateTime ToDateTime(this string datetime, char dateSpliter = '-', char timeSpliter = ':', char millisecondSpliter = ',')
{
   try
   {
      datetime = datetime.Trim();
      datetime = datetime.Replace("  ", " ");
      string[] body = datetime.Split(' ');
      string[] date = body[0].Split(dateSpliter);
      int year = date[0].ToInt();
      int month = date[1].ToInt();
      int day = date[2].ToInt();
      int hour = 0, minute = 0, second = 0, millisecond = 0;
      if (body.Length == 2)
      {
         string[] tpart = body[1].Split(millisecondSpliter);
         string[] time = tpart[0].Split(timeSpliter);
         hour = time[0].ToInt();
         minute = time[1].ToInt();
         if (time.Length == 3) second = time[2].ToInt();
         if (tpart.Length == 2) millisecond = tpart[1].ToInt();
      }
      return new DateTime(year, month, day, hour, minute, second, millisecond);
   }
   catch
   {
      return new DateTime();
   }
}

In this way, you can use

string datetime = "2009-05-08 14:40:52,531";
DateTime dt0 = datetime.TToDateTime();

DateTime dt1 = "2009-05-08 14:40:52,531".ToDateTime();
DateTime dt5 = "2009-05-08".ToDateTime();
DateTime dt2 = "2009/05/08 14:40:52".ToDateTime('/');
DateTime dt3 = "2009/05/08 14.40".ToDateTime('/', '.');
DateTime dt4 = "2009-05-08 14:40-531".ToDateTime('-', ':', '-');

If you are looking for single quote, it is

'

Just put your data into an Object like this:

var myObject = new Object();
myObject.name = "John";
myObject.age = 12;
myObject.pets = ["cat", "dog"];

Afterwards stringify it via:

var myString = JSON.stringify(myObject);

You don't need jQuery for this. It's pure JS.

The reason was when I dumped the DB I used following command :

mysqldump -h <host> -u <username> -p <database> > dumpfile.sql
dumpfile.sql

By mistaken dumpfile.sql added twice in the syntax.

Solution : I removed the dumpfile.sql text added to first line of the exported dumpfile.

This is the implemented code needed:

in Swift 3.0:

var dataString = String(data: fooData, encoding: String.Encoding.utf8)

or just

var dataString = String(data: fooData, encoding: .utf8)

Older swift version:

in Swift 2.0:

import Foundation

var dataString = String(data: fooData, encoding: NSUTF8StringEncoding)

in Swift 1.0:

var dataString = NSString(data: fooData, encoding:NSUTF8StringEncoding)

If you are searching by the fieldname1 value, try this:

var r = exitDictionary
   .Select(i => i.Value).Cast<Dictionary<string, object>>()
   .Where(d => d.ContainsKey("fieldname1"))
   .Select(d => d["fieldname1"]).Cast<List<Dictionary<string, string>>>()
   .SelectMany(d1 => 
       d1
        .Where(d => d.ContainsKey("valueTitle"))
        .Select(d => d["valueTitle"])
        .Where(v => v != null)).ToList();

If you are looking by the type of the value in the subDictionary (Dictionary<string, object> explicitly), you may do this:

var r = exitDictionary
   .Select(i => i.Value).Cast<Dictionary<string, object>>()
   .SelectMany(d=>d.Values)
   .OfType<List<Dictionary<string, string>>>()
   .SelectMany(d1 => 
       d1
        .Where(d => d.ContainsKey("valueTitle"))
        .Select(d => d["valueTitle"])
        .Where(v => v != null)).ToList();

Both alternatives will return:

title1
title2
title3
title1
title2
title3

If you use a comma inbetween the strings and the variable, like this:

print "If there was a birth every 7 seconds, there would be: ", births, "births"

The question is tagged with ubuntu, but the solution of un-commenting the extension=mysqli.dll is specific to windows. I am confused here?!, anyways, first thing run <? php phpinfo ?> and search for mysql* under Configuration heading. If you don't see such a thing implies you have not installed or enabled php-mysql. So first install php-mysql

sudo apt get install php-mysql

This command will install php-mysql depending on the php you have already installed, so no worries about the version!!.

Then comes the unix specific solution, in the php.ini file un-comment the line

extension=msql.so

verify that msql.so is present in /usr/lib/php/<timestamp_folder>, ELSE

extension=path/to/msql.so

Then finally restart the apache and mysql services, and you should now see the mysql section under Configrations heading in phpinfo page

I got its answer. Here is my code

<label for="db">Choose type</label>
<select name="dbType" id=dbType">
   <option>Choose Database Type</option>
   <option value="oracle">Oracle</option>
   <option value="mssql">MS SQL</option>
   <option value="mysql">MySQL</option>
   <option value="other">Other</option>
</select>

<div id="other" class="selectDBType" style="display:none;">
<label for="specify">Specify</label>
<input type="text" name="specify" placeholder="Specify Databse Type"/>
</div>

And my script is

$(function() {

        $('#dbType').change(function() {
            $('.selectDBType').slideUp("slow");
            $('#' + $(this).val()).slideDown("slow");
        });
    });

The date format for mysql insert query is YYYY-MM-DD

example:

INSERT INTO table_name (date_column) VALUE ('YYYY-MM-DD');

The following eight pseudo-elements are made available by WebKit for customizing a date input’s textbox:

::-webkit-datetime-edit
::-webkit-datetime-edit-fields-wrapper
::-webkit-datetime-edit-text
::-webkit-datetime-edit-month-field
::-webkit-datetime-edit-day-field
::-webkit-datetime-edit-year-field
::-webkit-inner-spin-button
::-webkit-calendar-picker-indicator

So if you thought the date input could use more spacing and a ridiculous color scheme you could add the following:

In external tables, if you drop it, it deletes only schema of the table, table data exists in physical location. So to deleted the data use hadoop fs - rmr tablename . Managed table hive will have full control on tables. In external tables users will have control on it.

The sys.maxint constant was removed, since there is no longer a limit to the value of integers. However, sys.maxsize can be used as an integer larger than any practical list or string index. It conforms to the implementation’s “natural” integer size and is typically the same as sys.maxint in previous releases on the same platform (assuming the same build options).

For me when I created a file and saved it as python file, I was getting this error during importing. I had to create a filename with the type ".py" , like filename.py and then save it as a python file. post trying to import the file worked for me.

class Program
{
    static void Main(string[] args)
    {

        int transactionDate = 20201010;
        int? transactionTime = 210000;

        var agreementDate = DateTime.Today;
        var previousDate = agreementDate.AddDays(-1);

        var agreementHour = 22;
        var agreementMinute = 0;
        var agreementSecond = 0;

        var startDate = new DateTime(previousDate.Year, previousDate.Month, previousDate.Day, agreementHour, agreementMinute, agreementSecond);
        var endDate = new DateTime(agreementDate.Year, agreementDate.Month, agreementDate.Day, agreementHour, agreementMinute, agreementSecond);

        DateTime selectedDate = Convert.ToDateTime(transactionDate.ToString().Substring(6, 2) + "/" + transactionDate.ToString().Substring(4, 2) + "/" + transactionDate.ToString().Substring(0, 4) + " " + string.Format("{0:00:00:00}", transactionTime));

        Console.WriteLine("Selected Date : " + selectedDate.ToString());
        Console.WriteLine("Start Date : " + startDate.ToString());
        Console.WriteLine("End Date : " + endDate.ToString());

        if (selectedDate > startDate && selectedDate <= endDate)
            Console.WriteLine("Between two dates..");
        else if (selectedDate <= startDate)
            Console.WriteLine("Less than or equal to the start date!");
        else if (selectedDate > endDate)
            Console.WriteLine("Greater than end date!");
        else
            Console.WriteLine("Out of date ranges!");
    }
}

If the order of the execution is not important and you need both some javascript AND some codebehind to be fired on an asp element, heres what you can do.

What you can take away from my example: I have a div covering the ASP control that I want both javascript and codebehind to be ran from. The div's onClick method AND the calendar's OnSelectionChanged event both get fired this way.

In this example, i am using an ASP Calendar control, and im controlling it from both javascript and codebehind:

Front end code:

        <div onclick="showHideModal();">
            <asp:Calendar 
                OnSelectionChanged="DatepickerDateChange" ID="DatepickerCalendar" runat="server" 
                BorderWidth="1px" DayNameFormat="Shortest" Font-Names="Verdana" 
                Font-Size="8pt" ShowGridLines="true" BackColor="#B8C9E1" BorderColor="#003E51" Width="100%"> 
                <OtherMonthDayStyle ForeColor="#6C5D34"> </OtherMonthDayStyle> 
                <DayHeaderStyle  ForeColor="black" BackColor="#D19000"> </DayHeaderStyle>
                <TitleStyle BackColor="#B8C9E1" ForeColor="Black"> </TitleStyle> 
                <DayStyle BackColor="White"> </DayStyle> 
                <SelectedDayStyle BackColor="#003E51" Font-Bold="True"> </SelectedDayStyle> 
            </asp:Calendar>
        </div>

Codebehind:

        protected void DatepickerDateChange(object sender, EventArgs e)
        {
            if (toFromPicked.Value == "MainContent_fromDate")
            {
                fromDate.Text = DatepickerCalendar.SelectedDate.ToShortDateString();
            }
            else
            {
                toDate.Text = DatepickerCalendar.SelectedDate.ToShortDateString();
            }
        }

n my case with Android 4.4.2 had to do some additional steps: (Make sure rn server is running npm start, delete app-debug.apk from android/app/build/outputs/apk , uninstall from android if previously installed and run following commands from root folder)

1_ create dir mkdir android/app/src/main/assets
2_ create file index.android.js which is a clone of index.js cp index.js index.android.js
3_ react-native link
4_ curl "http://localhost:8081/index.android.bundle?platform=android" -o "android/app/src/main/assets/index.android.bundle"
5_ react-native run-android

DateTime dt = DateTime.Now;            
Console.WriteLine("{0} {1}", dt, dt.Kind);
DateTime ut = DateTime.SpecifyKind(dt, DateTimeKind.Utc);
Console.WriteLine("{0} {1}", ut, ut.Kind);

Your html is not updated every 15 seconds. The cause could be browser caching. Add Math.random() to avoid browser caching, and it's better to wait until the DOM is fully loaded as pointed out by @shadow. But I think the main cause is the caching

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.0/jquery.min.js" />
<script type="text/javascript">
$(document).ready(function(){
    var auto_refresh = setInterval(
    function ()
    {
       $('.View').load('Small.php?' + Math.random()).fadeIn("slow");
    }, 15000); // refresh every 15000 milliseconds
});
</script>

You should use parameters in your query to prevent attacks, like if someone entered '); drop table ArticlesTBL;--' as one of the values.

string query = "INSERT INTO ArticlesTBL (ArticleTitle, ArticleContent, ArticleType, ArticleImg, ArticleBrief,  ArticleDateTime, ArticleAuthor, ArticlePublished, ArticleHomeDisplay, ArticleViews)";
query += " VALUES (@ArticleTitle, @ArticleContent, @ArticleType, @ArticleImg, @ArticleBrief, @ArticleDateTime, @ArticleAuthor, @ArticlePublished, @ArticleHomeDisplay, @ArticleViews)";

SqlCommand myCommand = new SqlCommand(query, myConnection);
myCommand.Parameters.AddWithValue("@ArticleTitle", ArticleTitleTextBox.Text);
myCommand.Parameters.AddWithValue("@ArticleContent", ArticleContentTextBox.Text);
// ... other parameters
myCommand.ExecuteNonQuery();

(xkcd)

Yes! In your settings.py define the following

LOGIN_REDIRECT_URL = '/your-path'

And have '/your-path' be a simple View that looks up self.request.user and does whatever logic it needs to return a HttpResponseRedirect object.

A better way might be to define a simple URL like '/simple' that does the lookup logic there. The URL looks more beautiful, saves you some work, etc.

ERB::Util.html_escape can be used anywhere. It is available without using require in Rails.
