You just need to restart your adb. Instruction for that is given in this Link

Ubuntu 10.04 comes with the Suhosin patch only, which does not give you configuration options. But you can install php5-suhosin to solve this:

apt-get update
apt-get install php5-suhosin

Now you can edit /etc/php5/conf.d/suhosin.ini and set:

suhosin.memory_limit = 1G

Then using ini_set will work in a script:

ini_set('memory_limit', '256M');

Call

perror("execl");

in case of error.

Sample:

if(read(fd, buf, 1)==-1) {
    perror("read");
}

The manpages of errno(3) and perror(3) are interesting, too...

Your gradle wrapper is missing, broken or corrupted.

What is gradle wrapper:
gradlew is the gradle wrapper executable - batch script on windows and shell script elsewhere. The wrapper script when invoked, downloads the defined gradle version and executes it. By distributing the wrapper with your project, anyone can work with it without needing to install Gradle beforehand. Even better, users of the build are guaranteed to use the version of Gradle that the build was designed to work with.

Restoring gradle wrapper:
It used to be that you needed to add a wrapper task to your build.gradle to restore gradle wrapper and all its dependencies. For instance:

task wrapper(type: Wrapper) {
    gradleVersion = '4.1'
}

Newer versions of gradle do not require this. It is now a built-in task. Just run:

gradle wrapper

You can also supply additional flags to specify versions etc

gradle wrapper --gradle-version 6.2 --distribution-type all

When you run this task, a gradle wrapper script, and the required jar files are added to your source folders. Properties are stored in gradle/wrapper/gradle-wrapper.properties

(You may need to install gradle locally to run this. brew install gradle on mac for instance. See more detailed instructions here)

Why was it missing in the first place?
OP seems to have deleted something that gradle wrapper depends on.

But a common reason is that a .gitignore entry prevents wrapper jars from being checked into git. Note that the .gitignore in effect may be in the source folder, or a global one in your user home folder or git global configuration. It is common to have a *.jar entry in .gitignore.

You can add an exception for gradlew's jar files in .gitignore

*.jar
!gradle/wrapper/gradle-wrapper.jar

or force add the wrapper jar into git

git add -f gradle/wrapper/gradle-wrapper.jar

In C# 5.0, this problem is fixed and you can close over loop variables and get the results you expect.

The language specification says:

8.8.4 The foreach statement

(...)

A foreach statement of the form

foreach (V v in x) embedded-statement

is then expanded to:

{
  E e = ((C)(x)).GetEnumerator();
  try {
      while (e.MoveNext()) {
          V v = (V)(T)e.Current;
          embedded-statement
      }
  }
  finally {
      … // Dispose e
  }
}

(...)

The placement of v inside the while loop is important for how it is captured by any anonymous function occurring in the embedded-statement. For example:

int[] values = { 7, 9, 13 };
Action f = null;
foreach (var value in values)
{
    if (f == null) f = () => Console.WriteLine("First value: " + value);
}
f();

If v was declared outside of the while loop, it would be shared among all iterations, and its value after the for loop would be the final value, 13, which is what the invocation of f would print. Instead, because each iteration has its own variable v, the one captured by f in the first iteration will continue to hold the value 7, which is what will be printed. (Note: earlier versions of C# declared v outside of the while loop.)

plot(t) is in this case the same as

plot(t[[1]], t[[2]])

As the error message says, x and y differ in length and that is because you plot a list with length 4 against 1:

> length(t)
[1] 4
> length(1)
[1] 1

In your second example you plot a list with elements named x and y, both vectors of length 2, so plot plots these two vectors.

Edit:

If you want to plot lines use

plot(t, type="l")

To read bytes use std::bitset

const int bits_in_byte = 8;

char myChar = 's';
cout << bitset<sizeof(myChar) * bits_in_byte>(myChar);

To write you need to use bit-wise operators such as & ^ | & << >>. make sure to learn what they do.

For example to have 00100100 you need to set the first bit to 1, and shift it with the << >> operators 5 times. if you want to continue writing you just continue to set the first bit and shift it. it's very much like an old typewriter: you write, and shift the paper.

For 00100100: set the first bit to 1, shift 5 times, set the first bit to 1, and shift 2 times:

const int bits_in_byte = 8;

char myChar = 0;
myChar = myChar | (0x1 << 5 | 0x1 << 2);
cout << bitset<sizeof(myChar) * bits_in_byte>(myChar);

Try the following

if (c is TForm) { 
 ...
}

Try this:

valgrind --leak-check=full -v ./your_program

As long as valgrind is installed it will go through your program and tell you what's wrong. It can give you pointers and approximate places where your leaks may be found. If you're segfault'ing, try running it through gdb.

If you don't like Math.round() you can use this simple approach as well:

int a = (int) (doubleVar + 0.5);

header( 'Location: http://www.yoursite.com/new_page.html' );

in your process.php file

You can password protect a SQLite3 DB. Before doing any operations, set the password as follows.

SQLiteConnection conn = new SQLiteConnection("Data Source=MyDatabase.sqlite;Version=3;");
conn.SetPassword("password");
conn.Open();

then next time you can access it like

conn = new SQLiteConnection("Data Source=MyDatabase.sqlite;Version=3;Password=password;");
conn.Open();

This wont allow any GUI editor to view your data. Some editors can decrypt the DB if you provide the password. The algorithm used is RSA.

Later if you wish to change the password, use

conn.ChangePassword("new_password");

To reset or remove password, use

conn.ChangePassword(String.Empty);

pandas >= 1.2

left.merge(right, how='cross')

import pandas as pd 

pd.__version__
# '1.2.0'

left = pd.DataFrame({'col1': [1, 2], 'col2': [3, 4]})
right = pd.DataFrame({'col3': [5, 6]}) 

left.merge(right, how='cross')

   col1  col2  col3
0     1     3     5
1     1     3     6
2     2     4     5
3     2     4     6

Indexes are ignored in the result.

Implementation wise, this uses the join on common key column method as described in the accepted answer. The upsides of using the API is that it saves you a lot of typing and handles some corner cases pretty well. I'd almost always recommend this syntax as my first preference for cartesian product in pandas unless you're looking for something more performant.

Java 8 provides Byte.toUnsignedInt to convert byte to int by unsigned conversion. In Oracle's JDK this is simply implemented as return ((int) x) & 0xff; because HotSpot already understands how to optimize this pattern, but it could be intrinsified on other VMs. More importantly, no prior knowledge is needed to understand what a call to toUnsignedInt(foo) does.

In total, Java 8 provides methods to convert byte and short to unsigned int and long, and int to unsigned long. A method to convert byte to unsigned short was deliberately omitted because the JVM only provides arithmetic on int and long anyway.

To convert an int back to a byte, just use a cast: (byte)someInt. The resulting narrowing primitive conversion will discard all but the last 8 bits.

None from the answers above really addresses the issue correctly. The reason is that we want to disable selection of the cell but not necessarily of subviews inside the cell.

In my case I was presenting a UISwitch in the middle of the row and I wanted to disable selection for the rest of the row (which is empty) but not for the switch! The proper way of doing that is hence in the method

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath

where a statement of the form

[cell setSelectionStyle:UITableViewCellSelectionStyleNone];

disables selection for the specific cell while at the same time allows the user to manipulate the switch and hence use the appropriate selector. This is not true if somebody disables user interaction through the

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

method which merely prepares the cell and does not allow interaction with the UISwitch.

Moreover, using the method

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

in order to deselect the cell with a statement of the form

[tableView deselectRowAtIndexPath:indexPath animated:NO];

still shows the row being selected while the user presses on the original contentView of the cell.

Just my two cents. I am pretty sure many will find this useful.

Try this if you unbind the onclick event by ID Then use:

$('#youLinkID').attr('onclick','').unbind('click');

Try this if you unbind the onclick event by Class Then use:

$('.className').attr('onclick','').unbind('click');

We had the same problem on a CentOS7 machine. Disabling the VERIFYHOST VERIFYPEER did not solve the problem, we did not have the cURL error anymore but the response still was invalid. Doing a wget to the same link as the cURL was doing also resulted in a certificate error.

-> Our solution also was to reboot the VPS, this solved it and we were able to complete the request again.

For us this seemed to be a memory corruption problem. Rebooting the VPS reloaded the libary in the memory again and now it works. So if the above solution from @clover does not work try to reboot your machine.

There is no "better" but the more common one is ||. They have different precedence and || would work like one would expect normally.

See also: Logical operators (the following example is taken from there):

// The result of the expression (false || true) is assigned to $e
// Acts like: ($e = (false || true))
$e = false || true;

// The constant false is assigned to $f and then true is ignored
// Acts like: (($f = false) or true)
$f = false or true;

create attribute name is "price_screen_tab_name". and access using this simple formula.

<?php $_product = $this->getProduct(); ?>
<?php echo $_product->getData('price_screen_tab_name');?>

From the composer help create-project command

The create-project command creates a new project from a given
package into a new directory. If executed without params and in a directory with a composer.json file it installs the packages for the current project.
You can use this command to bootstrap new projects or setup a clean
version-controlled installation for developers of your project.

[version]
You can also specify the version with the package name using = or : as separator.
To install unstable packages, either specify the version you want, or use the --stability=dev (where dev can be one of RC, beta, alpha or dev).

This command works:

composer create-project laravel/laravel=4.1.27 your-project-name --prefer-dist

This works with the * notation.

The different is .html() evaluate as a html, .text() avaluate as a text.
Consider a block of html
HTML

<div id="mydiv">
<div class="mydiv">
    This is a div container
    <ul>
      <li><a href="#">Link 1</a></li>
      <li><a href="#">Link 2</a></li>
    </ul>
    a text after ul
</div>
</div>

JS

var out1 = $('#mydiv').html();
var out2 = $('#mydiv').text();
console.log(out1) // This output all the html tag
console.log(out2) // This is output just the text 'This is a div container Link 1 Link 2 a text after ul'

The illustration is from this link http://api.jquery.com/text/

It will also be empty if the new Referrer Policy standard draft is used to prevent that the referer header is sent to the request origin. Example:

<meta name="referrer" content="none">

Although Chrome and Firefox have already implemented a draft version of the Referrer Policy, you should be careful with it because for example Chrome expects no-referrer instead of none (and I have seen also never somewhere).

Did something like that once:

CREATE TABLE exclusions(excl VARCHAR(250));
INSERT INTO exclusions(excl)
VALUES
       ('%timeline%'),
       ('%Placeholders%'),
       ('%Stages%'),
       ('%master_stage_1205x465%'),
       ('%Accessories%'),
       ('%chosen-sprite.png'),
('%WebResource.axd');
GO
CREATE VIEW ToBeDeleted AS 
SELECT * FROM chunks
       WHERE chunks.file_id IN
       (
       SELECT DISTINCT
             lf.file_id
       FROM LargeFiles lf
       WHERE lf.file_id NOT IN
             (
             SELECT DISTINCT
                    lf.file_id
             FROM LargeFiles lf
                LEFT JOIN exclusions e ON(lf.URL LIKE e.excl)
                WHERE e.excl IS NULL
             )
       );
GO
CHECKPOINT

SET NOCOUNT ON;
DECLARE @r INT;
SET @r = 1;

    DELETE TOP (10000) FROM ToBeDeleted;
    SET @r = @@ROWCOUNT  
END
GO

0123456789 is not a valid integer (usually zeros will be stripped)

I think something like this regexp would be better to use:

^[1-9]([0-9]*)$

(does not support signed numbers)

In my case, I was trying to upgrade my angular 6 project using ng update after that the entire universe collapse.

I was trying to update my project using this commands:

• ng update @angular/cli
• ng update @angular/core
• ng update @angular/material

And then I found a problem with rxjs package and I run also this command. - npm install --save rxjs

And then I get the error

No NgModule metadata found

I solve this by deleting my node_modules folder in the project root and then I run:

• npm install

That's is, all works nice.

To also highlight the menu item when one of the child pages is active, also check for the other class (current-page-ancestor) like below:

add_filter('nav_menu_css_class' , 'special_nav_class' , 10 , 2);

function special_nav_class ($classes, $item) {
    if (in_array('current-page-ancestor', $classes) || in_array('current-menu-item', $classes) ){
        $classes[] = 'active ';
    }
    return $classes;
}

If you are defining UICollectionViewFlowLayout in code, it will override Interface Builder configs. Hence you need to re-define the scrollDirection again.

let layout = UICollectionViewFlowLayout()
...
layout.scrollDirection = .Horizontal
self.awesomeCollectionView.collectionViewLayout = layout

You can easily detect which type and version of the browser, using this jquery

$(document).ready(function()
{
 if ( $.browser.msie ){
    if($.browser.version == '6.0')
    {   $('html').addClass('ie6');
    }
    else if($.browser.version == '7.0')
    {   $('html').addClass('ie7');
    }
    else if($.browser.version == '8.0')
    {   $('html').addClass('ie8');
    }
    else if($.browser.version == '9.0')
    {   $('html').addClass('ie9');
    }
 }
 else if ( $.browser.webkit )
 { $('html').addClass('webkit');
 }
 else if ( $.browser.mozilla )
 { $('html').addClass('mozilla');
 }
 else if ( $.browser.opera )
 { $('html').addClass('opera');
 }
});

This works for me when you need to open another dialog box by clicking a button inside a dialogue box and also close this one. Pass the values as params with a comma separator.

<v-btn absolute fab small slot="activator" top right color="primary" @click="(addTime = true),(ticketExpenseList = false)"><v-icon>add</v-icon></v-btn>

Here is what I used for TSQL which took care of the problem that my table name could contain the schema name and possibly the database name:

DECLARE @THETABLE varchar(100);
SET @THETABLE = 'theschema.thetable';
select i.*
  from sys.indexes i
 where i.object_id = OBJECT_ID(@THETABLE)
   and i.name is not NULL;

The use case for this is that I wanted the list of indexes for a named table so I could write a procedure that would dynamically compress all indexes on a table.

You can use JSTL tags together with EL expressions to avoid intermixing Java and HTML code:

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>
<html>
    <head>
    </head>
    <body>

        <c:out value="${x + 1}" />
        <c:out value="${param.name}" />
        // and so on

    </body>
</html>

Very simple using slice pipe (angular's core pipe), as you asked for data.title:

{{ data.title | slice:0:20 }}

From Angular common docs https://angular.io/api/common/SlicePipe

Is it really necessary for you to get a physical path?
For example, ImageView.setImageURI() and ContentResolver.openInputStream() allow you to access the contents of a file without knowing its real path.

It's not very intuitive but this works well for me ...

  mkdir remote.git & cd remote.git & git init
  git remote add origin $REPO
  git fetch origin $BRANCH:refs/remotes/origin/$BRANCH        

THEN run the git branch --track command ...

  git branch --track $BRANCH origin/$BRANCH

EDIT: Maybe your class for sending emails has an option for HTML emails and then you can use <br />

1) Double-quotes

$output = "Good news! The item# $item_number  on which you placed a bid of \$ $bid_price is now available for purchase at your bid price.\nThe seller, $bid_user is making this offer.\n\nItem Title : $title\n\nAll the best,\n $bid_user\n$email\n";

If you use double-quotes then \n will work (there will be no newline in browser but see the source code in your browser - the \n characters will be replaced for newlines)

2) Single quotes doesn't have the effect as the double-quotes above:

$output = 'Good news! The item# $item_number  on which you placed a bid of \$ $bid_price is now available for purchase at your bid price.\nThe seller, $bid_user is making this offer.\n\nItem Title : $title\n\nAll the best,\n $bid_user\n$email\n';

all characters will be printed as is (even variables!)

3) Line breaks in HTML

$html_output = "Good news! The item# $item_number  on which you placed a bid of <br />$ $bid_price is now available for purchase at your bid price.<br />The seller, $bid_user is making this offer.<br /><br />Item Title : $title<br /><br />All the best,<br /> $bid_user<br />$email<br />";

• There will be line breaks in your browser and variables will be replaced with their content.

This would be helpful

button.titleLabel.font = [UIFont fontWithName:@"YOUR FONTNAME" size:12.0f]

Based on @markhellewell answer I created a couple of alias functions that will do it for you. Just add these to your shell startup file

#list available jdks
alias jdks="/usr/libexec/java_home -V"
# jdk version switching - e.g. `jdk 6` will switch to version 1.6
function jdk() { 
  echo "Switching java version"; 
  export JAVA_HOME=`/usr/libexec/java_home -v 1.$1`; 
  java -version; 
}

See the Locale.getLanguage(), Locale.getCountry()... Store this combination in the database instead of the "programatic name"...
When you want to build the Locale back, use public Locale(String language, String country)

Here is a sample code :)

// May contain simple syntax error, I don't have java right now to test..
// but this is a bigger picture for your algo...
public String localeToString(Locale l) {
    return l.getLanguage() + "," + l.getCountry();
}

public Locale stringToLocale(String s) {
    StringTokenizer tempStringTokenizer = new StringTokenizer(s,",");
    if(tempStringTokenizer.hasMoreTokens())
    String l = tempStringTokenizer.nextElement();
    if(tempStringTokenizer.hasMoreTokens())
    String c = tempStringTokenizer.nextElement();
    return new Locale(l,c);
}

You can always use the stl:

auto min_value = *std::min_element(v.begin(),v.end());

The below examples might help understand:

def add_nums1(x,y):
    print(x+y)

def add_nums2(x,y):
    return x+y 

#----Function output is usable for further processing
add_nums2(10,20)/2
15.0

#----Function output can't be used further (gives TypeError)
add_nums1(10,20)/2

Method 1: Use a hash

Logic: A hash can have only unique keys, so iterate over array, assign any value to each element of array, keeping element as key of that hash. Return keys of the hash, its your unique array.

my @unique = keys {map {$_ => 1} @array};

Method 2: Extension of method 1 for reusability

Better to make a subroutine if we are supposed to use this functionality multiple times in our code.

sub get_unique {
    my %seen;
    grep !$seen{$_}++, @_;
}
my @unique = get_unique(@array);

Method 3: Use module List::MoreUtils

use List::MoreUtils qw(uniq);
my @unique = uniq(@array);

You need to assign different classes to each table.

Create a class in CSS with the dot '.' operator and write your properties inside each class. For example,

.table1 {
//some properties
}

.table2 {
//Some other properties
}

and use them in your html code.

Maybe, you have modified the structure of the war or deploying it on a different server version. Checkout these links Error deploying war into JBoss AS 7 (domain mode): "Failed to process phase STRUCTURE of deployment" and https://community.jboss.org/thread/199387?start=0&tstart=0&_sscc=t

There are already answers which give how to change Inner HTML of element.

But I would suggest, you should use some animation like Fade Out/ Fade In to change HTML which gives good effect of changed HTML rather instantly changing inner HTML.

Use animation to change Inner HTML

$('#regTitle').fadeOut(500, function() {
    $(this).html('Hello World!').fadeIn(500);
});

If you have many functions which need this, then you can call common function which changes inner Html.

function changeInnerHtml(elementPath, newText){
    $(elementPath).fadeOut(500, function() {
        $(this).html(newText).fadeIn(500);
    });
}

Please note that, the repeatable in repeatable read regards to a tuple, but not to the entire table. In ANSC isolation levels, phantom read anomaly can occur, which means read a table with the same where clause twice may return different return different result sets. Literally, it's not repeatable.

Yes, you can achieve this by using the following commands:

sqlite> .headers on
sqlite> .mode column

The result of a select on your table will then look like:

id          foo         bar         age         street      address
----------  ----------  ----------  ----------  ----------  ----------
1           val1        val2        val3        val4        val5
2           val6        val7        val8        val9        val10

As far as I understand it, the sort function in the collection class can only be used to sort collections implementing the comparable interface.

You are supplying it a array of integers. You should probably wrap this around one of the know Wrapper classes such as Integer. Integer implements comparable.

Its been a long time since I have worked on some serious Java, however reading some matter on the sort function will help.

Since no answer here mentions a perfect, fail-proof ID that is both PERSISTENT through system updates and exists in ALL devices (mainly due to the fact that there isn't an individual solution from Google), I decided to post a method that is the next best thing by combining two of the available identifiers, and a check to chose between them at run-time.

Before code, 3 facts:

1. TelephonyManager.getDeviceId() (a.k.a.IMEI) will not work well or at all for non-GSM, 3G, LTE, etc. devices, but will always return a unique ID when related hardware is present, even when no SIM is inserted or even when no SIM slot exists (some OEM's have done this).

2. Since Gingerbread (Android 2.3) android.os.Build.SERIAL must exist on any device that doesn't provide IMEI, i.e., doesn't have the aforementioned hardware present, as per Android policy.

3. Due to fact (2.), at least one of these two unique identifiers will ALWAYS be present, and SERIAL can be present at the same time that IMEI is.

Note: Fact (1.) and (2.) are based on Google statements

SOLUTION

With the facts above, one can always have a unique identifier by checking if there is IMEI-bound hardware, and fall back to SERIAL when it isn't, as one cannot check if the existing SERIAL is valid. The following static class presents 2 methods for checking such presence and using either IMEI or SERIAL:

import java.lang.reflect.Method;

import android.content.Context;
import android.content.pm.PackageManager;
import android.os.Build;
import android.provider.Settings;
import android.telephony.TelephonyManager;

I would advice on using getCleartextID_HARDCHECK. If the reflection doesn't stick in your environment, use the getCleartextID_SIMCHECK method instead, but take in consideration it should be adapted to your specific SIM-presence needs.

P.S.: Do please note that OEM's have managed to bug out SERIAL against Google policy (multiple devices with same SERIAL), and Google as stated there is at least one known case in a big OEM (not disclosed and I don't know which brand it is either, I'm guessing Samsung).

Disclaimer: This answers the original question of getting a unique device ID, but the OP introduced ambiguity by stating he needs a unique ID for an APP. Even if for such scenarios Android_ID would be better, it WILL NOT WORK after, say, a Titanium Backup of an app through 2 different ROM installs (can even be the same ROM). My solution maintains persistence that is independent of a flash or factory reset, and will only fail when IMEI or SERIAL tampering occurs through hacks/hardware mods.

I tried the following @janny loco's answer first and then reset anaconda to get it to work.

Step 1:

activate root
conda update -n root conda
conda update --all

Step 2:

anaconda-navigator --reset

After running the update commands in step 1 and not seeing any success, I reset anaconda by running the command above based on what I found here.

I am not sure if it was the combination of updating conda and reseting the navigator or just one of the two. So, please try accordingly.

Take a look QRCoder - pure C# open source QR code generator. Can be used in three lines of code

QRCodeGenerator qrGenerator = new QRCodeGenerator();
QRCodeGenerator.QRCode qrCode = qrGenerator.CreateQrCode(textBoxQRCode.Text, QRCodeGenerator.ECCLevel.Q);
pictureBoxQRCode.BackgroundImage = qrCode.GetGraphic(20);

Generally when I want to create a JSON or YAML string, I start out by building the Perl data structure, and then running a simple conversion on it. You could put a UI in front of the Perl data structure generation, e.g. a web form.

Converting a structure to JSON is very straightforward:

use strict;
use warnings;
use JSON::Any;

my $data = { arbitrary structure in here };
my $json_handler = JSON::Any->new(utf8=>1);
my $json_string = $json_handler->objToJson($data);

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();

I eventually settled for:

>>> import time
>>> time.mktime(time.gmtime())
1509467455.0

I prefer to use a DOS function. Feels cleaner to me.

SET SIZELIMIT=1000
CALL :FileSize %1 FileSize
IF %FileSize% GTR %SIZELIMIT% Echo Large file

GOTO :EOF

:FileSize
SET %~2=%~z1

GOTO :EOF

A quick way to do it on your Github repo would be as followed:

• Find the specific commit from your branch
• Beside the SHA id, click on 'Browse the repo at this point in the history'
• Here you can create a new branch from this commit

Graphviz - from the web page:

The Graphviz layout programs take descriptions of graphs in a simple text language, and make diagrams in several useful formats such as images and SVG for web pages, Postscript for inclusion in PDF or other documents; or display in an interactive graph browser. (Graphviz also supports GXL, an XML dialect.)

It's the simplest and most productive tool I've found to create a variety of boxes-and-lines diagrams. I have and use Visio and OmniGraffle, but there's always the temptation to make "just one more adjustment".

It's also quite easy to write code to produce the "dot file" format that Graphiz consumes, so automated diagram production is also nicely within reach.

It is wrong to have <input> as a direct child of a <form>

And by the way <input /> may fail on some doctype

Check it with http://validator.w3.org/check

document type does not allow element "INPUT" here; missing one of "P", "H1", "H2", "H3", "H4", "H5", "H6", "PRE", "DIV", "ADDRESS" start-tag

<input type="text" />

The mentioned element is not allowed to appear in the context in which you've placed it; the other mentioned elements are the only ones that are both allowed there and can contain the element mentioned. This might mean that you need a containing element, or possibly that you've forgotten to close a previous element.

One possible cause for this message is that you have attempted to put a block-level element (such as "<p>" or "<table>") inside an inline element (such as "<a>", "<span>", or "<font>").

property_exists( mixed $class , string $property )

if (property_exists($ob, 'a')) 

isset( mixed $var [, mixed $... ] )

if (isset($ob->a))

isset() will return false if property is null

Example 1:

$ob->a = null
var_dump(isset($ob->a)); // false

Example 2:

class Foo
{
   public $bar = null;
}

$foo = new Foo();

var_dump(property_exists($foo, 'bar')); // true
var_dump(isset($foo->bar)); // false

There are some tools and API's available for it. However, I do not think you'll find one for free ;)

There is for instance the OLicense suite: http://www.olicense.de/index.php?lang=en

Depends on implementation but I would use

(?i)G[a-b].

VARIATIONS:

(?i) case-insensitive mode ON    
(?-i) case-insensitive mode OFF

Modern regex flavors allow you to apply modifiers to only part of the regular expression. If you insert the modifier (?im) in the middle of the regex then the modifier only applies to the part of the regex to the right of the modifier. With these flavors, you can turn off modes by preceding them with a minus sign (?-i).

Description is from the page: https://www.regular-expressions.info/modifiers.html

If you're using a functional component, you can define defaults in the destructuring assignment, like so:

export default ({ children, id="menu", side="left", image={menu} }) => {
  ...
};

You don't appear to understand what still reachable means.

Anything still reachable is not a leak. You don't need to do anything about it.

I was dealing with this issue today, and I knew that I had something encoded as a bytes object that I was trying to serialize as json with json.dump(my_json_object, write_to_file.json). my_json_object in this case was a very large json object that I had created, so I had several dicts, lists, and strings to look at to find what was still in bytes format.

The way I ended up solving it: the write_to_file.json will have everything up to the bytes object that is causing the issue.

In my particular case this was a line obtained through

for line in text:
    json_object['line'] = line.strip()

I solved by first finding this error with the help of the write_to_file.json, then by correcting it to:

for line in text:
    json_object['line'] = line.strip().decode()

Another python3 implementation that involves the use of Abstract classes with super(). You should remember that

super().__init__(name, 10)

has the same effect as

Person.__init__(self, name, 10)

Remember there's a hidden 'self' in super(), So the same object passes on to the superclass init method and the attributes are added to the object that called it. Hence super()gets translated to Person and then if you include the hidden self, you get the above code frag.

from abc import ABCMeta, abstractmethod
class Person(metaclass=ABCMeta):
    name = ""
    age = 0

    def __init__(self, personName, personAge):
        self.name = personName
        self.age = personAge

    @abstractmethod
    def showName(self):
        pass

    @abstractmethod
    def showAge(self):
        pass


class Man(Person):

    def __init__(self, name, height):
        self.height = height
        # Person.__init__(self, name, 10)
        super().__init__(name, 10)  # same as Person.__init__(self, name, 10)
        # basically used to call the superclass init . This is used incase you want to call subclass init
        # and then also call superclass's init.
        # Since there's a hidden self in the super's parameters, when it's is called,
        # the superclasses attributes are a part of the same object that was sent out in the super() method

    def showIdentity(self):
        return self.name, self.age, self.height

    def showName(self):
        pass

    def showAge(self):
        pass


a = Man("piyush", "179")
print(a.showIdentity())

The :: are used to dereference scopes.

const int x = 5;

namespace foo {
  const int x = 0;
}

int bar() {
  int x = 1;
  return x;
}

struct Meh {
  static const int x = 2;
}

int main() {
  std::cout << x; // => 5
  {
    int x = 4;
    std::cout << x; // => 4
    std::cout << ::x; // => 5, this one looks for x outside the current scope
  }
  std::cout << Meh::x; // => 2, use the definition of x inside the scope of Meh
  std::cout << foo::x; // => 0, use the definition of x inside foo
  std::cout << bar(); // => 1, use the definition of x inside bar (returned by bar)
}

unrelated: cout and cin are not functions, but instances of stream objects.

EDIT fixed as Keine Lust suggested

You could use strftime with a %j format string:

>>> import datetime
>>> today = datetime.datetime.now()
>>> today.strftime('%j')
'065'

but if you wish to do comparisons or calculations with this number, you would have to convert it to int() because strftime() returns a string. If that is the case, you are better off using DzinX's answer.

ok , i've solved it by creating a handler on the onCreate of the service , and calling the gps functions through there .

The code is as simple as this:

final handler=new Handler(Looper.getMainLooper()); 

And then to force running things on the UI, I call post on it.

I have tried the solution which redirects 405 to 200, and in production environment(in my case, it's Google Load Balancing with Nginx Docker container), this hack causes some 502 errors(Google Load Balancing error code: backend_early_response_with_non_error_status).

In the end, I have made this work properly by replacing Nginx with OpenResty which is completely compatible with Nginx and have more plugins.

With ngx_coolkit, Now Nginx(OpenResty) could serve static files with POST request properly, here is the config file in my case:

server {
  listen 80;

  location / {
    override_method GET;
    proxy_pass http://127.0.0.1:8080;
  }
}

server {
  listen 8080;
  location / {
    root /var/www/web-static;
    index index.html;
    add_header Cache-Control no-cache;
  }
}

In the above config, I use override_method offered by ngx_coolkit to override the HTTP Method to GET.

Step by step self explaining commands for update of feature branch with the latest code from origin "develop" branch:

git checkout develop

git merge develop
git push origin feature_branch

You'll need to serialize your object into some kind of string representation. One possible string representation is JSON, and one of the easiest ways to serialize to/from JSON in android, if you ask me, is through Google GSON.

In that case you just put the string return value from (new Gson()).toJson(myObject); and retrieve the string value and use fromJson to turn it back into your object.

If your object isn't very complex, however, it might not be worth the overhead, and you could consider passing the separate values of the object instead.

Regarding the width and height:

var img = document.getElementById('imageId'); 

var width = img.clientWidth;
var height = img.clientHeight;

Regarding the filesize you can use performance

var size = performance.getEntriesByName(url)[0];
console.log(size.transferSize); // or decodedBodySize might differ if compression is used on server side

jQuery is a JavaScript library.

Read

wiki-jQuery, github, jQuery vs. javascript?

What is JQuery?

Before JQuery, developers would create their own small frameworks (the group of code) this would allow all the developers to work around all the bugs and give them more time to work on features, so the JavaScript frameworks were born. Then came the collaboration stage, groups of developers instead of writing their own code would give it away for free and creating JavaScript code sets that everyone could use. That is what JQuery is, a library of JavaScript code. The best way to explain JQuery and its mission is well stated on the front page of the JQuery website which says:

JQuery is a fast and concise JavaScript Library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development.

As you can see all JQuery is JavaScript. There is more than one type of JavaScript set of code sets like MooTools it is just that JQuery is the most popular.

Which is the best JavaScript or JQuery is a contentious discussion, really the answer is neither is best. They both have their roles I have worked on online applications where JQuery was not the right tool and what the application needed was straight JavaScript development. But for most websites JQuery is all that is needed. What a web developer needs to do is make an informed decision on what tools are best for their client. Someone first coming into web development does need some exposure to both technologies just using JQuery all the time does not teach the nuances of JavaScript and how it affects the DOM. Using JavaScript all the time slows projects down and because of the JQuery library has ironed most of the issues that JavaScript will have between each web browser it makes the deployment safe as it is sure to work across all platforms.

---

JavaScript is a language. jQuery is a library built with JavaScript to help JavaScript programmers who are doing common web tasks.

See here.

In C, \0 denotes a character with value zero. The following are identical:

char a = 0;
char b = '\0';

The utility of this escape sequence is greater inside string literals, which are arrays of characters:

char arr[] = "abc\0def\0ghi\0";

(Note that this array has two zero characters at the end, since string literals include a hidden, implicit terminal zero.)

This was My Mistake:

I had a minor update in a Push Notification content part and I did not even touch my code.

But I thought I might have to re-upload it in order to reflect that change in the latest version.

And I did.

Tried to upload 3 Builds One by One.

But Not a single build has shown in the Test Flight Version.(Shocked)

Later I realized my mistake that just by updating APNS content part without even touching my code, I was trying to upload a new build and was expecting to reflect it in the Test Flight. (So stupid of me)

The way I cleared my form input values was to add an id to my form tag. Then when I handleSubmit I call this.clearForm()

In the clearForm function I then use document.getElementById("myForm").reset();

import React, {Component } from 'react';
import './App.css';
import Button from './components/Button';
import Input from './components/Input';

class App extends Component {  
  state = {
    item: "", 
    list: []
}

componentDidMount() {
    this.clearForm();
  }

handleFormSubmit = event => {
   this.clearForm()
   event.preventDefault()
   const item = this.state.item

    this.setState ({
        list: [...this.state.list, item],
            })

}

handleInputChange = event => {
  this.setState ({
    item: event.target.value 
  })
}

clearForm = () => {
  document.getElementById("myForm").reset(); 
  this.setState({
    item: ""
  })
}



  render() {
    return (
      <form id="myForm">
      <Input

           name="textinfo"
           onChange={this.handleInputChange}
           value={this.state.item}
      />
      <Button
        onClick={this.handleFormSubmit}
      >  </Button>
      </form>
    );
  }
}

export default App;

I have to add an important comment. Everyone is mentioning that NOLOCKreads only dirty data. This is not precise. It is also possible that you'll get same row twice or whole row is skipped during your read. Reason is that you could ask for some data in same time when SQL Server is re-balancing b-tree.

Check another threads

https://stackoverflow.com/a/5469238/2108874

http://www.sqlmag.com/article/sql-server/quaere-verum-clustered-index-scans-part-iii.aspx)

With the NOLOCK hint (or setting the isolation level of the session to READ UNCOMMITTED) you tell SQL Server that you don't expect consistency, so there are no guarantees. Bear in mind though that "inconsistent data" does not only mean that you might see uncommitted changes that were later rolled back, or data changes in an intermediate state of the transaction. It also means that in a simple query that scans all table/index data SQL Server may lose the scan position, or you might end up getting the same row twice.

var script = $('<script type="text/javascript">// function </script>')
document.getElementsByTagName("head")[0].appendChild(script[0])

But in that case script will not be executed and functions will be not accessible in global namespase. To use code in <script> you need do as in you question

I've had a lot of issues with SVN before and one thing that has definitely caused me problems is modifying files outside of Eclipse or manually deleting folders (which contains the .svn folders), that has probably given me the most trouble.

edit You should also be careful not to interrupt SVN operations, though sometimes a bug may occur and this could cause the .lock file to not be removed, and hence your error.

We've used Ants Profiler Pro by Red Gate software in our project. It works really well for all .NET language-based applications.

We found that the .NET Garbage Collector is very "safe" in its cleaning up of in-memory objects (as it should be). It would keep objects around just because we might be using it sometime in the future. This meant we needed to be more careful about the number of objects that we inflated in memory. In the end, we converted all of our data objects over to an "inflate on-demand" (just before a field is requested) in order to reduce memory overhead and increase performance.

EDIT: Here's a further explanation of what I mean by "inflate on demand." In our object model of our database we use Properties of a parent object to expose the child object(s). For example if we had some record that referenced some other "detail" or "lookup" record on a one-to-one basis we would structure it like this:

class ParentObject
   Private mRelatedObject as New CRelatedObject
   public Readonly property RelatedObject() as CRelatedObject
      get
         mRelatedObject.getWithID(RelatedObjectID)
         return mRelatedObject
      end get
   end property
End class

We found that the above system created some real memory and performance problems when there were a lot of records in memory. So we switched over to a system where objects were inflated only when they were requested, and database calls were done only when necessary:

class ParentObject
   Private mRelatedObject as CRelatedObject
   Public ReadOnly Property RelatedObject() as CRelatedObject
      Get
         If mRelatedObject is Nothing
            mRelatedObject = New CRelatedObject
         End If
         If mRelatedObject.isEmptyObject
            mRelatedObject.getWithID(RelatedObjectID)
         End If
         return mRelatedObject
      end get
   end Property
end class

This turned out to be much more efficient because objects were kept out of memory until they were needed (the Get method was accessed). It provided a very large performance boost in limiting database hits and a huge gain on memory space.

working for me after turn off ads block extension in chrome, this error sometime appear because something that block http in browser

Just Clear the table body.

$("#tblbody").html("");

when curl is used to download a large file then CURLOPT_TIMEOUT is the main option you have to set for.

CURLOPT_RETURNTRANSFER has to be true in case you are getting file like pdf/csv/image etc.

You may find the further detail over here(correct url) Curl Doc

From that page:

curl_setopt($request, CURLOPT_TIMEOUT, 300); //set timeout to 5 mins

curl_setopt($request, CURLOPT_RETURNTRANSFER, true); // true to get the output as string otherwise false

Make sure this isn't happening from your DNS. For example Cloudflare has it where you can turn on development mode where it forces a purge on your stylesheets and images as Cloudflare offers accelerated cache. This will disable it and force it to update everytime someone visits your site.

You can set timeout like this,

con.setConnectTimeout(connectTimeout);
con.setReadTimeout(socketTimeout);

Yes, it is. Declare parameter as so:

@Sort varchar(50) = NULL

Now you don't even have to pass the parameter in. It will default to NULL (or whatever you choose to default to).

This worked perfectly for me:

Range("c1:c4") = Application.Transpose(Array("Loc", "uk", "us", "nj"))

If you had a way of automatically looking up the data (ie matching uk against employer id) then you could do that in VBA

• character_set_database: utf8mb4
• character_set_results: utf8mb4
• character_set_server: utf8mb4

Note: character_set_system stays "utf8"

These SQL commands do NOT WORK PERMANENTLY - only in a session:

A timestamp is a point in time. Typically this can be represented by a number of milliseconds past an epoc (the Unix Epoc of Jan 1 1970 12AM UTC). The format of that point in time depends on the time zone. While it is the same point in time, the "hours value" is not the same among time zones and one must take into account the offset from the UTC.

Here's some code to illustrate. A point is time is captured in three different ways.

var moment = require( 'moment' );

var localDate = new Date();
var localMoment = moment();
var utcMoment = moment.utc();
var utcDate = new Date( utcMoment.format() );

//These are all the same
console.log( 'localData unix = ' + localDate.valueOf() );
console.log( 'localMoment unix = ' + localMoment.valueOf() );
console.log( 'utcMoment unix = ' + utcMoment.valueOf() );

//These formats are different
console.log( 'localDate = ' + localDate );
console.log( 'localMoment string = ' + localMoment.format() );
console.log( 'utcMoment string = ' + utcMoment.format() );
console.log( 'utcDate  = ' + utcDate );

//One to show conversion
console.log( 'localDate as UTC format = ' + moment.utc( localDate ).format() );
console.log( 'localDate as UTC unix = ' + moment.utc( localDate ).valueOf() );

Which outputs this:

localData unix = 1415806206570
localMoment unix = 1415806206570
utcMoment unix = 1415806206570
localDate = Wed Nov 12 2014 10:30:06 GMT-0500 (EST)
localMoment string = 2014-11-12T10:30:06-05:00
utcMoment string = 2014-11-12T15:30:06+00:00
utcDate  = Wed Nov 12 2014 10:30:06 GMT-0500 (EST)
localDate as UTC format = 2014-11-12T15:30:06+00:00
localDate as UTC unix = 1415806206570

In terms of milliseconds, each are the same. It is the exact same point in time (though in some runs, the later millisecond is one higher).

As far as format, each can be represented in a particular timezone. And the formatting of that timezone'd string looks different, for the exact same point in time!

Are you going to compare these time values? Just convert to milliseconds. One value of milliseconds is always less than, equal to or greater than another millisecond value.

Do you want to compare specific 'hour' or 'day' values and worried they "came from" different timezones? Convert to UTC first using moment.utc( existingDate ), and then do operations. Examples of those conversions, when coming out of the DB, are the last console.log calls in the example.

Try this method. It is working for me.

@Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
    TextView textView = (TextView) view;
    ((TextView) adapterView.getChildAt(0)).setTextColor(Color.RED);
    ((TextView) adapterView.getChildAt(0)).setTextSize(20);
    Toast.makeText(this, textView.getText()+" Selected", Toast.LENGTH_SHORT).show();
}

Simply choose your background color of your item and specify the opacity separatly:

div { background-color:#000; opacity:0.8; }

You can do it using jQuery. Example:

<script src="https://code.jquery.com/jquery-1.11.2.min.js"></script>

<script>
    $.ajax({
        url : "next.php",
        type: "POST",
        data : "name=Denniss",
        success: function(data)
        {
            //data - response from server
            $('#response_div').html(data);
        }
    });
</script>

Just to add on to the other answers, before i knew my way around git, i was looking for some way to upload existing code to a new github (or other git) repo. Here's the brief that would save time for newbs:-

Assuming you have your NEW empty github or other git repo ready:-

cd "/your/repo/dir"
git clone https://github.com/user_AKA_you/repoName # (creates /your/repo/dir/repoName)
cp "/all/your/existing/code/*" "/your/repo/dir/repoName/"
git add -A
git commit -m "initial commit"
git push origin master

Alternatively if you have an existing local git repo

cd "/your/repo/dir/repoName"
#add your remote github or other git repo
git remote set-url origin https://github.com/user_AKA_you/your_repoName
git commit -m "new origin commit"
git push origin master

This might be useful for someone else: Using this sample html

<div class="ParentDiv">
    <label for="label">labelName</label>
    <input type="button" value="elementToSelect">
</div>
<div class="DontSelect">
    <label for="animal">pig</label>
    <input type="button" value="elementToSelect">
</div>

If for example, I want to select an element in the same section (e.g div) as a label, you can use this

//label[contains(., 'labelName')]/parent::*//input[@value='elementToSelect'] 

This just means, look for a label (it could anything like a, h2) called labelName. Navigate to the parent of that label (i.e. div class="ParentDiv"). Search within the descendants of that parent to find any child element with the value of elementToSelect. With this, it will not select the second elementToSelect with DontSelect div as parent.

The trick is that you can reduce search areas for an element by navigating to the parent first and then searching descendant of that parent for the element you need. Other Syntax like following-sibling::h2 can also be used in some cases. This means the sibling following element h2. This will work for elements at the same level, having the same parent.

In certain circumstances, it is better to use IN rather than EXISTS. In general, if the selective predicate is in the subquery, then use IN. If the selective predicate is in the parent query, then use EXISTS.

THIS IS FOR BEGINNERS,

Python automatically compiles your script to compiled code, so called byte code, before running it.

Running a script is not considered an import and no .pyc will be created.

For example, if you have a script file abc.py that imports another module xyz.py, when you run abc.py, xyz.pyc will be created since xyz is imported, but no abc.pyc file will be created since abc.py isn’t being imported.

If you need to create a .pyc file for a module that is not imported, you can use the py_compile and compileall modules.

The py_compile module can manually compile any module. One way is to use the py_compile.compile function in that module interactively:

>>> import py_compile
>>> py_compile.compile('abc.py')

This will write the .pyc to the same location as abc.py (you can override that with the optional parameter cfile).

You can also automatically compile all files in a directory or directories using the compileall module.

python -m compileall

If the directory name (the current directory in this example) is omitted, the module compiles everything found on sys.path

var newObj = { a: 4, b: 0.5 , c: 0.35, d: 5 };
var maxValue = Math.max(...Object.values(newObj))
var minValue = Math.min(...Object.values(newObj))

If you really gotta be fast (not that I believe you do):

char[] chars = sourceDate.toCharArray();
chars[10] = ' ';
String targetDate = new String(chars, 0, 19);

The %run magic has a parameter file_finder that it uses to get the full path to the file to execute (see here); as you note, it just looks in the current directory, appending ".py" if necessary.

There doesn't seem to be a way to specify which file finder to use from the %run magic, but there's nothing to stop you from defining your own magic command that calls into %run with an appropriate file finder.

As a very nasty hack, you could override the default file_finder with your own:

IPython.core.magics.execution.ExecutionMagics.run.im_func.func_defaults[2] = my_file_finder

To be honest, at the rate the IPython API is changing that's as likely to continue to work as defining your own magic is.

If body contains a io.StringIO, you have to do like below:

How to use autoexpect to pipe a password into a command:

These steps are illustrated with an Ubuntu 12.10 desktop. The exact commands for your distribution may be slightly different.

This is dangerous because you risk exposing whatever password you use to anyone who can read the autoexpect script file.

DO NOT expose your root password or power user passwords by piping them through expect like this. Root kits WILL find this in an instant and your box is owned.

EXPECT spawns a process, reads text that comes in then sends text predefined in the script file.

1. Make sure you have expect and autoexpect installed:

   sudo apt-get install expect
   sudo apt-get install expect-dev
   

2. Read up on it:

   man expect
   man autoexpect
   

3. Go to your home directory:

   cd /home/el
   

4. User el cannot chown a file to root and must enter a password:

   touch testfile.txt
   sudo chown root:root testfile.txt 
      [enter password to authorize the changing of the owner]
   

5. This is the password entry we want to automate. Restart the terminal to ensure that sudo asks us for the password again. Go to /home/el again and do this:

   touch myfile.txt
   
   autoexpect -f my_test_expect.exp sudo chown root:root myfile.txt
   
       [enter password which authorizes the chown to root]
   
   autoexpect done, file is my_test_expect.exp
   

6. You have created my_test_expect.exp file. Your super secret password is stored plaintext in this file. This should make you VERY uncomfortable. Mitigate some discomfort by restricting permissions and ownership as much as possible:

   sudo chown el my_test_expect.exp     //make el the owner.
   sudo chmod 700 my_test_expect.exp    //make file only readable by el.
   

7. You see these sorts of commands at the bottom of my_test_expect.exp:

   set timeout -1
   spawn sudo chown root:root myfile.txt
   match_max 100000
   expect -exact "\[sudo\] password for el: "
   send -- "YourPasswordStoredInPlaintext\r"
   expect eof
   

8. You will need to verify that the above expect commands are appropriate. If the autoexpect script is being overly sensitive or not sensitive enough then it will hang. In this case it's acceptable because the expect is waiting for text that will always arrive.

9. Run the expect script as user el:

   expect my_test_expect.exp 
   spawn sudo chown root:root myfile.txt
   [sudo] password for el: 
   

10. The password contained in my_test_expect.exp was piped into a chown to root by user el. To see if the password was accepted, look at myfile.txt:

    ls -l
    -rw-r--r--  1 root root          0 Dec  2 14:48 myfile.txt
    

It worked because it is root, and el never entered a password. If you expose your root, sudo, or power user password with this script, then acquiring root on your box will be easy. Such is the penalty for a security system that lets everybody in no questions asked.

Live demo

first, check its offset every time you scroll the page

$(document).scroll(function() {
    checkOffset();
});

and make its position absolute if it has been downed under 10px before the footer.

function checkOffset() {
    if($('#social-float').offset().top + $('#social-float').height() 
                                           >= $('#footer').offset().top - 10)
        $('#social-float').css('position', 'absolute');
    if($(document).scrollTop() + window.innerHeight < $('#footer').offset().top)
        $('#social-float').css('position', 'fixed'); // restore when you scroll up
}

notice that #social-float's parent should be sibling of the footer

<div class="social-float-parent">
    <div id="social-float">
        something...
    </div>
</div>
<div id="footer">
</div>

good luck :)

rewrite the whole function as below:

bool IsValidNumber(char * string)
{
   for(int i = 0; i < strlen( string ); i ++)
   {
      //ASCII value of 0 = 48, 9 = 57. So if value is outside of numeric range then fail
      //Checking for negative sign "-" could be added: ASCII value 45.
      if (string[i] < 48 || string[i] > 57)
         return FALSE;
   }

   return TRUE;
}

In case you want to download the repo from your shell/terminal it should work like this:

wget https://user:[email protected]/user-name/repo-name/get/master.tar.bz2

or whatever download URL you might have.

Please make sure the user:password are both URL-encoded. So for instance if your username contains the @ symbol then replace it with %40.

You need to specify the path where your chromedriver is located.

1. Download chromedriver for your desired platform from here.

2. Place chromedriver on your system path, or where your code is.

3. If not using a system path, link your chromedriver.exe (For non-Windows users, it's just called chromedriver):

   browser = webdriver.Chrome(executable_path=r"C:\path\to\chromedriver.exe")
   

   (Set executable_path to the location where your chromedriver is located.)

   If you've placed chromedriver on your System Path, you can shortcut by just doing the following:

   browser = webdriver.Chrome()

4. If you're running on a Unix-based operating system, you may need to update the permissions of chromedriver after downloading it in order to make it executable:

   chmod +x chromedriver

5. That's all. If you're still experiencing issues, more info can be found on this other StackOverflow article: Can't use chrome driver for Selenium

The whole file is an array and there are objects and other arrays (e.g. cars) in the whole array of the file.

As you say, the outermost layer of your JSON blob is an array. Therefore, your parser will return a JSONArray. You can then get JSONObjects from the array ...

  JSONArray a = (JSONArray) parser.parse(new FileReader("c:\\exer4-courses.json"));

  for (Object o : a)
  {
    JSONObject person = (JSONObject) o;

    String name = (String) person.get("name");
    System.out.println(name);

    String city = (String) person.get("city");
    System.out.println(city);

    String job = (String) person.get("job");
    System.out.println(job);

    JSONArray cars = (JSONArray) person.get("cars");

    for (Object c : cars)
    {
      System.out.println(c+"");
    }
  }

For reference, see "Example 1" on the json-simple decoding example page.

Another way would be to use attributes of a suitable object, e.g. like so:

function plus(a,b) { return a+b; };

Plus = { a: function(x) { return { b: function(y) { return plus(x,y) }}}, 
         b: function(y) { return { a: function(x) { return plus(x,y) }}}};

sum = Plus.a(3).b(5);

Of course for this made up example it is somewhat meaningless. But in cases where the function looks like

do_something(some_connection_handle, some_context_parameter, some_value)

it might be more useful. It also could be combined with "parameterfy" idea to create such an object out of an existing function in a generic way. That is for each parameter it would create a member that can evaluate to a partial evaluated version of the function.

This idea is of course related to Schönfinkeling aka Currying.

You can do this easily using openWRT. If yo use a captive portal you can mix php and openWRT and make a relation between the IP and the mac.

You can write a simple PHP code using:

 $localIP = getHostByName(getHostName()); 

Later, using openWRT you can go to /tmp/dhcp.leases, you will get something with the form:

 e4:a7:a0:29:xx:xx 10.239.3.XXX DESKTOP-XXX 

There, you have the mac, the IP address and the hostname.

As you can see from the many answers, there are several solutions. One instance of LBYL (look before you leap) has not been mentioned yet, the has_key() method:

my_dict = {}

def add (key):
    if my_dict.has_key(key):
        my_dict[key] += 1
    else:
        my_dict[key] = 1

if __name__ == '__main__':
    add("foo")
    add("bar")
    add("foo")
    print my_dict

Another approach can be manually using batch rename option

Right click on the file -> File Custom Commands -> Batch Rename and you can replace h. with half.

This will work for linux based gui using WinSCP etc

I have this challenge when working on an Ubuntu 18.04 Linux server.

Here's how I fixed it:

Run the command below to determine the location of your version.sh file:

sudo find / -name "version.sh"

For me the output was:

/opt/tomcat/bin/version.sh

Then, using the output, run the file (version.sh) as a shell script (sh):

sh /opt/tomcat/bin/version.sh

That's all.

I hope this helps

Their feature sets are not at all the same. Sqlite is an embedded database which has no network capabilities (unless you add them). So you can't use it on a network.

If you need

• Network access - for example accessing from another machine;
• Any real degree of concurrency - for example, if you think you are likely to want to run several queries at once, or run a workload that has lots of selects and a few updates, and want them to go smoothly etc.
• a lot of memory usage, for example, to buffer parts of your 1Tb database in your 32G of memory.

You need to use mysql or some other server-based RDBMS.

Note that MySQL is not the only choice and there are plenty of others which might be better for new applications (for example pgSQL).

Sqlite is a very, very nice piece of software, but it has never made claims to do any of these things that RDBMS servers do. It's a small library which runs SQL on local files (using locking to ensure that multiple processes don't screw the file up). It's really well tested and I like it a lot.

Also, if you aren't able to choose this correctly by yourself, you probably need to hire someone on your team who can.

For BSD or GNU grep you can use -B num to set how many lines before the match and -A num for the number of lines after the match.

grep -B 3 -A 2 foo README.txt

If you want the same number of lines before and after you can use -C num.

grep -C 3 foo README.txt

This will show 3 lines before and 3 lines after.

Basically local variables aren't automatically initialized. Hence using them without initializing would result in an exception.

Only the following variables are automatically initialized to their default values:

• Static variables
• Instance variables of class and struct instances
• Array elements

The default values are as follows (assigned in default constructor of a class):

• The default value of a variable of reference type is null.
• For integer types, the default value is 0
• For char, the default value is `\u0000'
• For float, the default value is 0.0f
• For double, the default value is 0.0d
• For decimal, the default value is 0.0m
• For bool, the default value is false
• For an enum type, the default value is 0
• For a struct type, the default value is obtained by setting all value type fields to their default values

As far as later parts of your question are conerned:

• The reason why all variables which are not automatically initialized to default values should be initialized is a restriction imposed by compiler.
• private bool foo = false; This is indeed redundant since this is an instance variable of a class. Hence this would be initialized to false in the default constructor. Hence no need to set this to false yourself.

Alternative to broadening permissions in your php config, you could change the user specified in your nginx config.

On the first line of your nginx.conf excerpt above, the user and group are specified as www and www, respectively.

user  www www;

Meanwhile, your php config probably specifies a user and group of www-data:

listen.owner = www-data
listen.group = www-data

You might change the line in your nginx.conf, to any of the following, then:

user www-data www;
user www-data www-data; # or any group, really, since you have the user matching
user www www-data; # requires that your php listen.mode gives rw access to the group

Something like this should definitely work:

private List<Date> getListOfDaysBetweenTwoDates(Date startDate, Date endDate) {
    List<Date> result = new ArrayList<Date>();
    Calendar start = Calendar.getInstance();
    start.setTime(startDate);
    Calendar end = Calendar.getInstance();
    end.setTime(endDate);
    end.add(Calendar.DAY_OF_YEAR, 1); //Add 1 day to endDate to make sure endDate is included into the final list
    while (start.before(end)) {
        result.add(start.getTime());
        start.add(Calendar.DAY_OF_YEAR, 1);
    }
    return result;
}

For The Rest Of Us

Here is a simple and clear example of how this works

Regex: ([a-zA-Z0-9]+)([\s]+)([a-zA-Z ]+)([\s]+)([0-9]+)

String: "!* UserName10 John Smith 01123 *!"

group(0): UserName10 John Smith 01123
group(1): UserName10
group(2):  
group(3): John Smith
group(4):  
group(5): 01123

As you can see, I have created FIVE groups which are each enclosed in parentheses.

I included the !* and *! on either side to make it clearer. Note that none of those characters are in the RegEx and therefore will not be produced in the results. Group(0) merely gives you the entire matched string (all of my search criteria in one single line). Group 1 stops right before the first space because the space character was not included in the search criteria. Groups 2 and 4 are simply the white space, which in this case is literally a space character, but could also be a tab or a line feed etc. Group 3 includes the space because I put it in the search criteria ... etc.

Hope this makes sense.

I had the same error with xcopy in connection with the Test Engine. I am using VisualStudio Professional 2013. By default Test -> Test Settings -> Keep Test Execution Engine Running seems to be the reason for my error code 4 with xcopy. Switching it off solved the problem. The execution engine seems to keep hold on some .dlls.

Since $.browser is deprecated, here is an alternative solution:

/**
 * Returns the version of Internet Explorer or a -1
 * (indicating the use of another browser).
 */
function getInternetExplorerVersion()
{
    var rv = -1; // Return value assumes failure.

    if (navigator.appName == 'Microsoft Internet Explorer')
    {
        var ua = navigator.userAgent;
        var re  = new RegExp("MSIE ([0-9]{1,}[\.0-9]{0,})");
        if (re.exec(ua) != null)
            rv = parseFloat( RegExp.$1 );
    }

    return rv;
}

function checkVersion()
{
    var msg = "You're not using Internet Explorer.";
    var ver = getInternetExplorerVersion();

    if ( ver > -1 )
    {
        if ( ver >= 8.0 ) 
            msg = "You're using a recent copy of Internet Explorer."
        else
            msg = "You should upgrade your copy of Internet Explorer.";
    }

    alert( msg );
}

However, the reason that its deprecated is because jQuery wants you to use feature detection instead.

An example:

$("p").html("This frame uses the W3C box model: <span>" +
        jQuery.support.boxModel + "</span>");

And last but not least, the most reliable way to check IE versions:

// ----------------------------------------------------------
// A short snippet for detecting versions of IE in JavaScript
// without resorting to user-agent sniffing
// ----------------------------------------------------------
// If you're not in IE (or IE version is less than 5) then:
//     ie === undefined
// If you're in IE (>=5) then you can determine which version:
//     ie === 7; // IE7
// Thus, to detect IE:
//     if (ie) {}
// And to detect the version:
//     ie === 6 // IE6
//     ie > 7 // IE8, IE9 ...
//     ie < 9 // Anything less than IE9
// ----------------------------------------------------------

// UPDATE: Now using Live NodeList idea from @jdalton

var ie = (function(){

    var undef,
        v = 3,
        div = document.createElement('div'),
        all = div.getElementsByTagName('i');

    while (
        div.innerHTML = '<!--[if gt IE ' + (++v) + ']><i></i><![endif]-->',
        all[0]
    );

    return v > 4 ? v : undef;

}());

There are apparently different levels of authentication. Most articles I read tell you to set the MaxAllowedZone to '1' which means that local machine zone and intranet zone are allowed but '4' allows access for 'all' zones.

This is how my registry looks (I wasn't sure it would work with the wild cards but it seems to work for me):

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"MaxAllowedZone"=dword:00000004

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions]
"UrlAllowList"="\\\\<network_path_root>;\\\\<network_path_root>\*;\\ies-inc.local;http://www.*;http://*;https://www.*;https://*;"

As an additional note, weirdly the "UrlAllowList" key was required to make this work on another PC but not my test one. It's probably not required at all but when I added it, it fixed the problem. The user may have not closed the original file or something like that. So just a consideration. I suggest try the least and test it, then add if needed. Once you confirm, you can deploy if needed. Good Luck!

Edit: P.S. Another method that worked was mapping the path to the network locally by using mklink /d (symbolic linking in Windows 7 or newer) but mapping a network drive letter (Z: for testing) did not work. Just food for thought and I did not have to 'Unblock' any files. Also the accepted 'Solution' did not resolve the issue for me.

Properties encapsulate fields, thus enabling you to perform additional processing on the value to be set or retrieved. It is typically overkill to use properties if you will not be doing any pre- or postprocessing on the field value.

So, there are three parts. Reading, storing and sending.

Here's the reading part:

var fs = require('fs');

function readFiles(dirname, onFileContent, onError) {
  fs.readdir(dirname, function(err, filenames) {
    if (err) {
      onError(err);
      return;
    }
    filenames.forEach(function(filename) {
      fs.readFile(dirname + filename, 'utf-8', function(err, content) {
        if (err) {
          onError(err);
          return;
        }
        onFileContent(filename, content);
      });
    });
  });
}

Here's the storing part:

var data = {};
readFiles('dirname/', function(filename, content) {
  data[filename] = content;
}, function(err) {
  throw err;
});

The sending part is up to you. You may want to send them one by one or after reading completion.

If you want to send files after reading completion you should either use sync versions of fs functions or use promises. Async callbacks is not a good style.

Additionally you asked about stripping an extension. You should proceed with questions one by one. Nobody will write a complete solution just for you.

After several tries, I got it! I'm setting the keyboard values programmatically like this:

myEditText.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_VARIATION_PASSWORD);

Or if you want you can edit the XML like so:

android: inputType = "numberPassword"

Both configs will display password bullets, so we need to create a custom ClickableSpan class:

private class NumericKeyBoardTransformationMethod extends PasswordTransformationMethod {
    @Override
    public CharSequence getTransformation(CharSequence source, View view) {
        return source;
    }
}

Finally we need to implement it on the EditText in order to display the characters typed.

myEditText.setTransformationMethod(new NumericKeyBoardTransformationMethod());

This is how my keyboard looks like now:

The AJAX request never has the opportunity to NOT follow the redirect (i.e., it must follow the redirect). More information can be found in this answer https://stackoverflow.com/a/2573589/965648

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

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

this would print mark

1.For Chrome & IE

<script language="javascript">
function printDiv(divName) {
var printContents = document.getElementById(divName).innerHTML;
var originalContents = document.body.innerHTML;
document.getElementById('header').style.display = 'none';
document.getElementById('footer').style.display = 'none';
document.body.innerHTML = printContents;

window.print();


document.body.innerHTML = originalContents;
}

</script>
<div id="div_print">
<div id="header" style="background-color:White;"></div>
<div id="footer" style="background-color:White;"></div>
</div>

2. For FireFox as l2aelba said,

Add moznomarginboxes attribute in Example :

<html moznomarginboxes mozdisallowselectionprint>

You can pass props by passing them to <RouteHandler> (in v0.13.x) or the Route component itself in v1.0;

// v0.13.x
<RouteHandler/>
<RouteHandler someExtraProp={something}/>

// v1.0
{this.props.children}
{React.cloneElement(this.props.children, {someExtraProp: something })}

(from the upgrade guide at https://github.com/rackt/react-router/releases/tag/v1.0.0)

All child handlers will receive the same set of props - this may be useful or not depending on the circumstance.

for i in range(len(Data)):
    Data[i, 1] = Data[i-lookback:i, 0].sum() / lookback

Try this piece of code. I think it's simpler and does the job. lookback is the window of the moving average.

In the Data[i-lookback:i, 0].sum() I have put 0 to refer to the first column of the dataset but you can put any column you like in case you have more than one column.

After not able to find a good universal solution I made something of my own. I have not tested it for a very large list.

It takes care of nested keys,arrays or just about anything.

Here is the github and demo

app.filter('xf', function() {
    function keyfind(f, obj) {
        if (obj === undefined)
            return -1;
        else {
            var sf = f.split(".");
            if (sf.length <= 1) {
                return obj[sf[0]];
            } else {
                var newobj = obj[sf[0]];
                sf.splice(0, 1);
                return keyfind(sf.join("."), newobj)
            }
        }

    }
    return function(input, clause, fields) {
        var out = [];
        if (clause && clause.query && clause.query.length > 0) {
            clause.query = String(clause.query).toLowerCase();
            angular.forEach(input, function(cp) {
                for (var i = 0; i < fields.length; i++) {
                    var haystack = String(keyfind(fields[i], cp)).toLowerCase();
                    if (haystack.indexOf(clause.query) > -1) {
                        out.push(cp);
                        break;
                    }
                }
            })
        } else {
            angular.forEach(input, function(cp) {
                out.push(cp);
            })
        }
        return out;
    }

})

Emoji

You can use colors for text as others mentioned in their answers.

But you can use emojis instead! for example you can use You can use ?? for warning messages and for error messages.

Or simply use these note books as a color:

: error message
: warning message
: ok status message
: action message
: canceled status message
: Or anything you like and want to recognize immediately by color

Bonus:

This method also helps you to quickly scan and find logs directly in the source code.

_{But linux and Windows CMD default emoji font is not colorful by default and you may want to make them colorful, first.}

For me what worked was: (right click)project->android tools->clear lint markers. Although for some reason the Manifest reverted to the old (lower) minimum API level, but after I changed it back to the new (higher) API level there was no red error underline and the project now uses the new minimum API level.

Edit: Sorry, I see you were using Android Studio, not Eclipse. But I guess there is a similar 'clear lint markers' in Studio somewhere and it might solve the problem.

In my case SSL certificate was invalid for iframe domain, so make sure that iframe URL you're trying to send messages to is opening w/o any issues (in case you load your iframe over https).

From your above needs, you will need to use both Python (to export pandas data frame) and VBA (to delete existing worksheet content and copy/paste external data).

With Python: use the to_csv or to_excel methods. I recommend the to_csv method which performs better with larger datasets.

# DF TO EXCEL
from pandas import ExcelWriter

writer = ExcelWriter('PythonExport.xlsx')
yourdf.to_excel(writer,'Sheet5')
writer.save()

# DF TO CSV
yourdf.to_csv('PythonExport.csv', sep=',')

With VBA: copy and paste source to destination ranges.

Fortunately, in VBA you can call Python scripts using Shell (assuming your OS is Windows).

Sub DataFrameImport()
  'RUN PYTHON TO EXPORT DATA FRAME
  Shell "C:\pathTo\python.exe fullpathOfPythonScript.py", vbNormalFocus

  'CLEAR EXISTING CONTENT
  ThisWorkbook.Worksheets(5).Cells.Clear

  'COPY AND PASTE TO WORKBOOK
  Workbooks("PythonExport").Worksheets(1).Cells.Copy
  ThisWorkbook.Worksheets(5).Range("A1").Select
  ThisWorkbook.Worksheets(5).Paste
End Sub

Alternatively, you can do vice versa: run a macro (ClearExistingContent) with Python. Be sure your Excel file is a macro-enabled (.xlsm) one with a saved macro to delete Sheet 5 content only. Note: macros cannot be saved with csv files.

import os
import win32com.client
from pandas import ExcelWriter

if os.path.exists("C:\Full Location\To\excelsheet.xlsm"):
  xlApp=win32com.client.Dispatch("Excel.Application")
  wb = xlApp.Workbooks.Open(Filename="C:\Full Location\To\excelsheet.xlsm")

  # MACRO TO CLEAR SHEET 5 CONTENT
  xlApp.Run("ClearExistingContent")
  wb.Save() 
  xlApp.Quit()
  del xl

  # WRITE IN DATA FRAME TO SHEET 5
  writer = ExcelWriter('C:\Full Location\To\excelsheet.xlsm')
  yourdf.to_excel(writer,'Sheet5')
  writer.save() 

I have done something like this abstract class that can be used in place of TextView.OnEditorActionListener type.

abstract class OnTextEndEditingListener : TextView.OnEditorActionListener {

    override fun onEditorAction(textView: TextView?, actionId: Int, event: KeyEvent?): Boolean {

        if(actionId == EditorInfo.IME_ACTION_SEARCH ||
                actionId == EditorInfo.IME_ACTION_DONE ||
                actionId == EditorInfo.IME_ACTION_NEXT ||
                event != null &&
                event.action == KeyEvent.ACTION_DOWN &&
                event.keyCode == KeyEvent.KEYCODE_ENTER) {

            if(event == null || !event.isShiftPressed) {
                // the user is done typing.
                return onTextEndEditing(textView, actionId, event)
            }
        }
        return false // pass on to other listeners
    }

    abstract fun onTextEndEditing(textView: TextView?, actionId: Int, event: KeyEvent?) : Boolean
}

I was thinking the error is due to "s3:ListObjects" action but I had to add the action "s3:ListBucket" to solve the issue "AccessDenied for ListObjects for S3 bucket"

I found a solution for my problem while writing my question !

Going into my remote session i tried two key combinations, and it solved the problem on my Desktop : Alt+Enter and Ctrl+Enter (i don't know which one solved the problem though)

I tried to reproduce the problem, but i couldn't... but i'm almost sure it's one of the key combinations described in the question above (since i experienced this problem several times)

So it seems the problem comes from the use of RDP (windows7 and 8)

Update 2017: Problem occurs on Windows 10 aswell.

You are trying to access pop as if was a list or a tupple, but pop is not. It's a method.

You need to use the CONCAT() function in MySQL for string concatenation:

UPDATE categories SET code = CONCAT(code, '_standard') WHERE id = 1;

The HttpServletRequest object provides a map of parameters already. See request.getParameterMap() for more details.

There's a theme available specifically for this

options: {
  theme: 'maximized'
}

from the Google chart docs:

Currently only one theme is available:

'maximized' - Maximizes the area of the chart, and draws the legend and all of the labels inside the chart area. Sets the following options:

chartArea: {width: '100%', height: '100%'},
legend: {position: 'in'},
titlePosition: 'in', axisTitlesPosition: 'in',
hAxis: {textPosition: 'in'}, vAxis: {textPosition: 'in'}

In Python 3, your can use the method from PY4E - Python for Everybody.

We can solve both these problems by using the string methods lower, punctuation, and translate. The translate is the most subtle of the methods. Here is the documentation for translate:

your_string.translate(your_string.maketrans(fromstr, tostr, deletestr))

Replace the characters in fromstr with the character in the same position in tostr and delete all characters that are in deletestr. The fromstr and tostr can be empty strings and the deletestr parameter can be omitted.

Your can see the "punctuation":

In [10]: import string

In [11]: string.punctuation
Out[11]: '!"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~'  

For your example:

In [12]: your_str = "Hey, you - what are you doing here!?"

In [13]: line = your_str.translate(your_str.maketrans('', '', string.punctuation))

In [14]: line = line.lower()

In [15]: words = line.split()

In [16]: print(words)
['hey', 'you', 'what', 'are', 'you', 'doing', 'here']

For more information, you can refer:

• PY4E - Python for Everybody
• str.translate
• str.maketrans
• Python String maketrans() Method

If you want to group by date in MySQL then use the code below:

 SELECT COUNT(id)
 FROM stats
 GROUP BY DAYOFMONTH(record_date)

Hope this saves some time for the ones who are going to find this thread.

see if their duplicate jars or dependencies your adding remove it and your error will be gone: Eg: if you add android:supportv4 jar and also dependency you will get the error so remove the jar error will be gone

This is taken from the MVC sample project

@if (ViewBag.ShowRemoveButton)
      {
         using (Html.BeginForm("RemoveLogin", "Manage"))
           {
              @Html.AntiForgeryToken()
                  <div>
                     @Html.Hidden("company_name", account)
                     @Html.Hidden("returnUrl", Model.returnUrl)
                     <input type="submit" class="btn btn-default" value="Remove" title="Remove your email address from @account" />
                  </div>
            }
        }

In some ways, your question seems very legitimate, but I still might label it an XY problem. I'm guessing the end result is that you want to display the sorted values in some way? As Bergi said in the comments, you can never quite rely on Javascript objects ( {i_am: "an_object"} ) to show their properties in any particular order.

For the displaying order, I might suggest you take each key of the object (ie, i_am) and sort them into an ordered array. Then, use that array when retrieving elements of your object to display. Pseudocode:

var keys = [...]
var sortedKeys = [...]
for (var i = 0; i < sortedKeys.length; i++) {
  var key = sortedKeys[i];
  addObjectToTable(json[key]);
}

In general I put it in a special folder "res" or "resources as already said, but after for the web application, I copy the log4j.properties with the ant task to the WEB-INF/classes directory. It is the same like letting the file at the root of the src/ folder but generally I prefer to see it in a dedicated folder.

With Maven, the usual place to put is in the folder src/main/resources as answered in this other post. All resources there will go to your build in the root classpath (e.g. target/classes/)

If you want a powerful logger, you can have also a look to slf4j library which is a logger facade and can use the log4j implementation behind.

We can sort the list in one of two ways:

1. Using Comparator : When required to use the sort logic in multiple places If you want to use the sorting logic in a single place, then you can write an anonymous inner class as follows, or else extract the comparator and use it in multiple places

  Collections.sort(arrayList, new Comparator<ActiveAlarm>() {
        public int compare(ActiveAlarm o1, ActiveAlarm o2) {
            //Sorts by 'TimeStarted' property
            return o1.getTimeStarted()<o2.getTimeStarted()?-1:o1.getTimeStarted()>o2.getTimeStarted()?1:doSecodaryOrderSort(o1,o2);
        }

        //If 'TimeStarted' property is equal sorts by 'TimeEnded' property
        public int doSecodaryOrderSort(ActiveAlarm o1,ActiveAlarm o2) {
            return o1.getTimeEnded()<o2.getTimeEnded()?-1:o1.getTimeEnded()>o2.getTimeEnded()?1:0;
        }
    });

We can have null check for the properties, if we could have used 'Long' instead of 'long'.

2. Using Comparable(natural ordering): If sort algorithm always stick to one property: write a class that implements 'Comparable' and override 'compareTo' method as defined below

class ActiveAlarm implements Comparable<ActiveAlarm>{

public long timeStarted;
public long timeEnded;
private String name = "";
private String description = "";
private String event;
private boolean live = false;

public ActiveAlarm(long timeStarted,long timeEnded) {
    this.timeStarted=timeStarted;
    this.timeEnded=timeEnded;
}

public long getTimeStarted() {
    return timeStarted;
}

public long getTimeEnded() {
    return timeEnded;
}

public int compareTo(ActiveAlarm o) {
    return timeStarted<o.getTimeStarted()?-1:timeStarted>o.getTimeStarted()?1:doSecodaryOrderSort(o);
}

public int doSecodaryOrderSort(ActiveAlarm o) {
    return timeEnded<o.getTimeEnded()?-1:timeEnded>o.getTimeEnded()?1:0;
}

}

call sort method to sort based on natural ordering

Collections.sort(list);

You can do this with pure CSS but you will need to hard code the offset scroll amounts, which may not be ideal should you be changing page content- or should dimensions of your content change on say window resize.

You're likely best placed to use e.g. jQuery, specifically:

$('html, body').stop().animate({
   scrollTop: element.offset().top
}, 1000);

A complete implementation may be:

$('#up, #down').on('click', function(e){
    e.preventDefault();
    var target= $(this).get(0).id == 'up' ? $('#down') : $('#up');
    $('html, body').stop().animate({
       scrollTop: target.offset().top
    }, 1000);
});

Where element is the target element to scroll to and 1000 is the delay in ms before completion.

Demo Fiddle

The benefit being, no matter what changes to your content dimensions, the function will not need to be altered.

If we see logically programming language and scripting language so this is 99.09% same . because we use same concept like loop , control condition ,variable and all so we can say yes both are same but there is only one thing is different between them that is in C/C++ and other programming language we compile the code before execution . but in the PHP , JavaScript and other scripting language we don't need to compile we directly execute in the browser.

From MDSN article, Controlling Transactions (Database Engine).

If a run-time statement error (such as a constraint violation) occurs in a batch, the default behavior in the Database Engine is to roll back only the statement that generated the error. You can change this behavior using the SET XACT_ABORT statement. After SET XACT_ABORT ON is executed, any run-time statement error causes an automatic rollback of the current transaction. Compile errors, such as syntax errors, are not affected by SET XACT_ABORT. For more information, see SET XACT_ABORT (Transact-SQL).

In your case it will rollback the complete transaction when any of inserts fail.

You can create the array in the caller, which is the main function, and pass the array to the callee which is your myFunction(). Thus myFunction can fill the string into the array. However, you need to declare myFunction() as

char* myFunction(char * buf, int buf_len){
  strncpy(buf, "my string", buf_len);
  return buf;
}

And in main function, myFunction should be called in this way:

char array[51];
memset(array, 0, 51); /* All bytes are set to '\0' */
printf("%s", myFunction(array, 50)); /* The buf_len argument  is 50, not 51. This is to make sure the string in buf is always null-terminated (array[50] is always '\0') */

However, a pointer is still used.

for a non-nested dict (since the title does not mention that case, it might be interesting for other people)

{str(k): str(v) for k, v in my_dict.items()}

When your project gets bigger, you might need some structure, so that your HTML page can reference files located in subfolders.

Assuming you drag your html_files folder to Xcode and select the Create folder references option, the following Swift code ensures that the WKWebView supports also the resulting folder structure:

import WebKit

@IBOutlet weak var webView: WKWebView!

if let path = Bundle.main.path(forResource: "sample", ofType: "html", inDirectory: "html_files") {
    webView.load( URLRequest(url: URL(fileURLWithPath: path)) )
}

This means that if your sample.html file contains an <img src="subfolder/myimage.jpg"> tag, then the image file myimage.jpg in subfolder will also be loaded and displayed.

I have run into this same issue - not sure why, and when it happens the only way I have ever gotten the chart to force update is to change something in the chart definition itself, which can easily be done via VBA as in:

Dim C As ChartObject: Set C = Me.ChartObjects("chart name")
C.Chart.ChartTitle.Text = C.Chart.ChartTitle.Text + "1"

There may be a better answer that gets to the bottom of the problem - but I thought this might help. Working on the sheet I would do a quick Ctrl-X, Ctrl-V on a piece of the chart (or the whole thing) to force the chart to update.

The method find will return the character position in a string. Then, if you want remove every thing from the character, do this:

mystring = "123?567"
mystring[ 0 : mystring.index("?")]

>> '123'

If you want to keep the character, add 1 to the character position.

Note: this no longer works due to https://github.com/Homebrew/brew/pull/612

I had the same problem today. I uninstalled (unbrewed??) openssl 1.0.2 and installed 1.0.1 also with homebrew. Dotnet new/restore/run then worked fine.

Install openssl 101:
brew install homebrew/versions/openssl101
Linking:
brew link --force homebrew/versions/openssl101

I've found a solution to solve my problem: I search the properties files using the Groovy Maven plugin.

As my properties file is necessarily in current directory, in ../ or in ../.., I wrote a small Groovy code that checks these three folders.

Here is the extract of my pom.xml:

<!-- Use Groovy to search the location of the properties file. -->

                    String p = project.properties['env-properties-file'];
                    File f = new File(p); 
                    if (!f.exists()) {
                        f = new File("../" + p);
                        if (!f.exists()) {
                            f = new File("../../" + p);
                        }
                    }
                    project.properties['env-properties-file-by-groovy'] = f.getAbsolutePath();
            </source>

This is working, but I don't really like it.

So, if you have a better solution, do not hesitate to post!

There's many forms of timeout, are you after the connection timeout, request timeout or time to live (time before TCP connection stops).

The default TimeToLive on Firefox is 115s (network.http.keep-alive.timeout)

The default connection timeout on Firefox is 250s (network.http.connection-retry-timeout)

The default request timeout for Firefox is 30s (network.http.pipelining.read-timeout).

The time it takes to do an HttpRequest depends on if a connection has been made this has to be within 250s which I'm guessing you're not after. You're probably after the request timeout which I think is 30,000ms (30s) so to conclude I'd say it's timing out with a connection time out that's why you got a response back after ~150s though I haven't really tested this.

WinObjC? Windows Bridge for iOS (previously known as ‘Project Islandwood’).

Windows Bridge for iOS (also referred to as WinObjC) is a Microsoft open source project that provides an Objective-C development environment for Visual Studio/Windows. In addition, WinObjC provides support for iOS API compatibility. While the final release will happen later this fall (allowing the bridge to take advantage of new tooling capabilities that will ship with the upcoming Visual Studio 2015 Update),

The bridge is available to the open-source community now in its current state. Between now and the fall. The iOS bridge as an open-source project under the MIT license. Given the ambition of the project, making it easy for iOS developers to build and run apps on Windows.

Salmaan Ahmed has an in-depth post on the Windows Bridge for iOS http://blogs.windows.com/buildingapps/2015/08/06/windows-bridge-for-ios-lets-open-this-up/ discussing the compiler, runtime, IDE integration, and what the bridge is and isn’t. Best of all, the source code for the iOS bridge is live on GitHub right now.

The iOS bridge supports both Windows 8.1 and Windows 10 apps built for x86 and x64 processor architectures, and soon we will add compiler optimizations and support for ARM, which adds mobile support.

Spring MVC is deeply integreated in Spring, Struts MVC is not.

if you want to find index for more than 2 occurrence:

public static int ordinalIndexOf(String fullText,String subText,int pos){

    if(fullText.contains(subText)){
        if(pos <= 1){
            return fullText.indexOf(subText);
        }else{
            --pos;
            return fullText.indexOf(subText, ( ordinalIndexOf(fullText,subText,pos) + 1) );
        }
    }else{
        return -1;
    }

}

Use AsyncTaskLoader to keep your data safe even if the activity changes, instead of using AsyncTask that is a better way to build apps than preventing screen rotation.

This one I found simple solutions:

row = myArray.map((cell, i) => {

    if (i == myArray.length - 1) {
      return <div> Test Data 1</div>;
    }
    return <div> Test Data 2</div>;
  });

Here the strsplit solution for a dataframe using dplyr package

col1 = c("TGAS_1121", "MGAS_1432", "ATGAS_1121") 
col2 = c("T", "M", "A") 
df = data.frame(col1, col2)
df
        col1 col2
1  TGAS_1121    T
2  MGAS_1432    M
3 ATGAS_1121    A

df<-mutate(df,col1=as.character(col1))
df2<-mutate(df,col1=sapply(strsplit(df$col1, split='_', fixed=TRUE),function(x) (x[2])))
df2

  col1 col2
1 1121    T
2 1432    M
3 1121    A

If you remember which branch was checked out before (e.g. master) you could simply

git checkout master

to get out of detached HEAD state.

Generally speaking: git checkout <branchname> will get you out of that.

If you don't remember the last branch name, try

git checkout -

This also tries to check out your last checked out branch.

In swift 3:

// exclude alpha and numeric == "full" encoding
stringUrl = stringUrl.addingPercentEncoding(withAllowedCharacters: .alphanumerics)!;

// exclude hostname and symbols &,/ and etc
stringUrl = stringUrl.addingPercentEncoding(withAllowedCharacters: .urlHostAllowed)!;

Well, my answer is not just the summary of all the solutions, but it offers more than that.

Section (1):

In general solutions:

I had four errors of this kind (‘metadata file could not be found’) along with one error saying 'Source File Could Not Be Opened (‘Unspecified error ‘)'.

I tried to get rid of ‘metadata file could not be found’ error. For that, I read many posts, blogs, etc. and found these solutions may be effective (summarizing them over here):

1. Restart Visual Studio and try building again.

2. Go to 'Solution Explorer'. Right click on Solution. Go to Properties. Go to 'Configuration Manager'. Check if the checkboxes under 'Build' are checked or not. If any or all of them are unchecked, then check them and try building again.

3. If the above solution(s) do not work, then follow sequence mentioned in step 2 above, and even if all the checkboxes are checked, uncheck them, check again and try to build again.

4. Build Order and Project Dependencies:

   Go to 'Solution Explorer'. Right click on Solution. Go to 'Project Dependencies...'. You will see two tabs: 'Dependencies' and 'Build Order'. This build order is the one in which solution builds. Check the project dependencies and the build order to verify if some project (say 'project1') which is dependent on other (say 'project2') is trying to build before that one (project2). This might be the cause for the error.

5. Check the path of the missing .dll:

   Check the path of the missing .dll. If the path contains space or any other invalid path character, remove it and try building again.

   If this is the cause, then adjust the build order.

Section (2):

My particular case:

I tried all the steps above with various permutations and combinations with restarting Visual Studio a few times. But, it did not help me.

So, I decided to get rid of other error I was coming across ('Source File Could Not Be Opened (‘Unspecified error ‘)').

I came across a blog post: TFS Error–Source File Could Not Be Opened (‘Unspecified error ‘)

I tried the steps mentioned in that blog post, and I got rid of the error 'Source File Could Not Be Opened (‘Unspecified error ‘)' and surprisingly I got rid of other errors (‘metadata file could not be found’) as well.

Section (3):

Moral of the story:

Try all solutions as mentioned in section (1) above (and any other solutions) for getting rid of the error. If nothing works out, as per the blog mentioned in section (2) above, delete the entries of all source files which are no longer present in the source control and the file system from your .csproj file.

<div class="container" style="width: 100%;">
    <div class="sidebar" style="width: 200px; float: left;">
        Sidebar
    </div>
    <div class="content" style="margin-left: 202px;">
        content 
    </div>
</div>

This will be cross browser compatible. Without the margin-left you will run into issues with content running all the way to the left if you content is longer than your sidebar.

A tty is a terminal (it stands for teletype - the original terminals used a line printer for output and a keyboard for input!). A terminal is a basically just a user interface device that uses text for input and output.

A pty is a pseudo-terminal - it's a software implementation that appears to the attached program like a terminal, but instead of communicating directly with a "real" terminal, it transfers the input and output to another program.

For example, when you ssh in to a machine and run ls, the ls command is sending its output to a pseudo-terminal, the other side of which is attached to the SSH daemon.

There are some good answers for it. I want to explain it through demo per Doc

• CMD defines default commands and/or parameters for a container. CMD is an instruction that is best to use if you need a default command which users can easily override. If a Dockerfile has multiple CMDs, it only applies the instructions from the last one.
• ENTRYPOINT is preferred when you want to define a container with a specific executable.

You cannot override an ENTRYPOINT when starting a container unless you add the --entrypoint flag.

1. CMD

Docker file

  FROM centos:8.1.1911

  CMD ["echo", "Hello Docker"]

Run result

$ sudo docker run <image-id>
Hello Docker
$ sudo docker run <image-id> hostname   # hostname is exec to override CMD
244be5006f32

2. ENTRYPOINT

Docker file

  FROM centos:8.1.1911

  ENTRYPOINT ["echo", "Hello Docker"]

Run result

$ sudo docker run <image-id>
Hello Docker
$ sudo docker run <image-id> hostname   # hostname as parameter to exec
Hello Docker hostname

3. There are many situations in which combining CMD and ENTRYPOINT would be the best solution for your Docker container. In such cases, the executable is defined with ENTRYPOINT, while CMD specifies the default parameter.

Docker file

  FROM centos:8.1.1911

  ENTRYPOINT ["echo", "Hello"]
  CMD ["Docker"]

Run result

$ sudo docker run <image-id>
Hello Docker
$ sudo docker run <image-id> Ben
Hello Ben

You can find the ObjectId constructor on require('mongoose').Types. Here is an example:

var mongoose = require('mongoose');
var id = mongoose.Types.ObjectId();

id is a newly generated ObjectId.

You can read more about the Types object at Mongoose#Types documentation.

Inspired by VB.Net Generics List(Of Integer), I created my own module for that. Maybe you find it useful, too or you'd like to extend for additional methods e.g. to remove items again:

'Save module with name: ListOfInteger

Public Function ListLength(list() As Integer) As Integer
On Error Resume Next
ListLength = UBound(list) + 1
On Error GoTo 0
End Function

Public Sub ListAdd(list() As Integer, newValue As Integer)
ReDim Preserve list(ListLength(list))
list(UBound(list)) = newValue
End Sub

Public Function ListContains(list() As Integer, value As Integer) As Boolean
ListContains = False
Dim MyCounter As Integer
For MyCounter = 0 To ListLength(list) - 1
    If list(MyCounter) = value Then
        ListContains = True
        Exit For
    End If
Next
End Function

Public Sub DebugOutputList(list() As Integer)
Dim MyCounter As Integer
For MyCounter = 0 To ListLength(list) - 1
    Debug.Print list(MyCounter)
Next
End Sub

You might use it as follows in your code:

Public Sub IntegerListDemo_RowsOfAllSelectedCells()
Dim rows() As Integer

Set SelectedCellRange = Excel.Selection
For Each MyCell In SelectedCellRange
    If IsEmpty(MyCell.value) = False Then
        If ListOfInteger.ListContains(rows, MyCell.Row) = False Then
            ListAdd rows, MyCell.Row
        End If
    End If
Next
ListOfInteger.DebugOutputList rows

End Sub

If you need another list type, just copy the module, save it at e.g. ListOfLong and replace all types Integer by Long. That's it :-)

You can use the code below to find a specific value.

WHERE col1 LIKE '%[%]75%'

When you want a single digit number after the% sign, you can write the following code.

WHERE col2 LIKE '%[%]_'

For Bash/Python, here is a basic wrapper around python's simplejson:

json_parser() {
    local jsonfile="my_json_file.json"
    local tc="import simplejson,sys; myjsonstr=sys.stdin.read(); "`
            `"myjson=simplejson.loads(myjsonstr);"
    # Build python print command based on $@
    local printcmd="print myjson"
    for (( argn=1; argn<=$#; argn++ )); do
        printcmd="$printcmd['${!argn}']"
    done
    local result=$(python -c "$tc $printcmd.keys()" <$jsonfile 2>/dev/null \
        || python -c "$tc $printcmd" <$jsonfile 2>/dev/null)
    # For returning space-separated values
    echo $result|sed -e "s/[]|[|,|']//g"
    #echo $result 
}

It really only handles the nested-dictionary style of data, but it works for what I needed, and is useful for walking through the json. It could probably be adapted to taste.

Anyway, something homegrown for those not wanting to source in yet another external dependency. Except for python, of course.

Ex. json_parser {field1} {field2} would run print myjson['{field1}']['{field2}'], yielding either the keys or the values associated with {field2}, space-separated.

To extend on what womp posted, you can pass new View Data while retaining the existing View Data if you use the constructor overload of the ViewDataDictionary like so:

Html.RenderPartial(
      "ProductImageForm", 
       image, 
       new ViewDataDictionary(this.ViewData) { { "index", index } }
); 

Kotlin: (If anyone needs)

var mText = text.substring(0, text.length.coerceAtMost(20))

You need to decode data from input string into unicode, before using it, to avoid encoding problems.

field.text = data.decode("utf8")

You might want to look into Eclim, an Eclipse server that allows you to use Eclipse functionality from within your favorite text editor. For python-related functionality, it uses Rope, PyFlakes, and PyLint under the hood.

In addition to Tim's answer, this issue occurred for me when I was splitting up a refactoring a file, splitting it up into their own files.

VSCode, for some reason, indented parts of my [class] code, which caused this issue. This was hard to notice at first, but after I realised the code was indented, I formatted the code and the issue disappeared.

for example, everything after the first line of the Class definition was auto-indented during the paste.

export class MyClass extends Something<string> {
    public blah: string = null;

    constructor() { ... }
  }

Objects will be cleaned up when they are no longer being used and when the garbage collector sees fit. Sometimes, you may need to set an object to null in order to make it go out of scope (such as a static field whose value you no longer need), but overall there is usually no need to set to null.

Regarding disposing objects, I agree with @Andre. If the object is IDisposable it is a good idea to dispose it when you no longer need it, especially if the object uses unmanaged resources. Not disposing unmanaged resources will lead to memory leaks.

You can use the using statement to automatically dispose an object once your program leaves the scope of the using statement.

using (MyIDisposableObject obj = new MyIDisposableObject())
{
    // use the object here
} // the object is disposed here

Which is functionally equivalent to:

MyIDisposableObject obj;
try
{
    obj = new MyIDisposableObject();
}
finally
{
    if (obj != null)
    {
        ((IDisposable)obj).Dispose();
    }
}

"Using HTML5/Canvas/JavaScript to take screenshots" answers your problem.

You can use JavaScript/Canvas to do the job but it is still experimental.

An easy fix

If you have only one type of collections (e.g. scatter with no error bars) you can also change the colours after that you have plotted them, this sometimes is easier to perform.

import matplotlib.pyplot as plt
from random import randint
import numpy as np

#Let's generate some random X, Y data X = [ [frst group],[second group] ...]
X = [ [randint(0,50) for i in range(0,5)] for i in range(0,24)]
Y = [ [randint(0,50) for i in range(0,5)] for i in range(0,24)]
labels = range(1,len(X)+1)

fig = plt.figure()
ax = fig.add_subplot(111)
for x,y,lab in zip(X,Y,labels):
        ax.scatter(x,y,label=lab)

The only piece of code that you need:

#Now this is actually the code that you need, an easy fix your colors just cut and paste not you need ax.
colormap = plt.cm.gist_ncar #nipy_spectral, Set1,Paired  
colorst = [colormap(i) for i in np.linspace(0, 0.9,len(ax.collections))]       
for t,j1 in enumerate(ax.collections):
    j1.set_color(colorst[t])


ax.legend(fontsize='small')

The output gives you differnent colors even when you have many different scatter plots in the same subplot.

    ByteArrayOutputStream out = new ByteArrayOutputStream();

public static Object deserialize(byte[] data) throws IOException, ClassNotFoundException {
    ByteArrayInputStream in = new ByteArrayInputStream(data);
