I use HttpWebRequest to GET from the web service, which returns me a JSON string. It looks something like this for a GET:

// Returns JSON string
string GET(string url) 
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    try {
        WebResponse response = request.GetResponse();
        using (Stream responseStream = response.GetResponseStream()) {
            StreamReader reader = new StreamReader(responseStream, System.Text.Encoding.UTF8);
            return reader.ReadToEnd();
        }
    }
    catch (WebException ex) {
        WebResponse errorResponse = ex.Response;
        using (Stream responseStream = errorResponse.GetResponseStream())
        {
            StreamReader reader = new StreamReader(responseStream, System.Text.Encoding.GetEncoding("utf-8"));
            String errorText = reader.ReadToEnd();
            // log errorText
        }
        throw;
    }
}

I then use JSON.Net to dynamically parse the string. Alternatively, you can generate the C# class statically from sample JSON output using this codeplex tool: http://jsonclassgenerator.codeplex.com/

POST looks like this:

// POST a JSON string
void POST(string url, string jsonContent) 
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    request.Method = "POST";

    System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();
    Byte[] byteArray = encoding.GetBytes(jsonContent);

    request.ContentLength = byteArray.Length;
    request.ContentType = @"application/json";

    using (Stream dataStream = request.GetRequestStream()) {
        dataStream.Write(byteArray, 0, byteArray.Length);
    }
    long length = 0;
    try {
        using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) {
            length = response.ContentLength;
        }
    }
    catch (WebException ex) {
        // Log exception and throw as for GET example above
    }
}

I use code like this in automated tests of our web service.

In Mysql use the following function pass the parameters as using POINT(LONG,LAT)

CREATE FUNCTION `distance`(a POINT, b POINT)
 RETURNS double
    DETERMINISTIC
BEGIN

RETURN

GLength( LineString(( PointFromWKB(a)), (PointFromWKB(b)))) * 100000; -- To Make the distance in meters

END;

I bumped into this too and found a solution.

First on how I got into this problem. I have a project which builds in x86. Then I used the Configuration Manager to add x64, and I hit this problem.

By looking at BuildLog.htm carefully, I saw both of these listed as linker options:

/MACHINE:X64  
/machine:X86 

I could not find anywhere in the Property Pages dialog where I could change this, so I opened up the .vcproj file and looked for the appropriate line and changed it to:

AdditionalOptions=" /STACK:10000000 /machine:x64 /debug"

and problem solved.

And this is an alternative.If you are returning as list then it is simple to get the values.

def select_choice():
    ...
    return [i, card]

values = select_choice()

print values[0]
print values[1]

So far all the answers are about that %n does, but not why anyone would want it in the first place. I find it's somewhat useful with sprintf/snprintf, when you might need to later break up or modify the resulting string, since the value stored is an array index into the resulting string. This application is a lot more useful, however, with sscanf, especially since functions in the scanf family don't return the number of chars processed but the number of fields.

Another really hackish use is getting a pseudo-log10 for free at the same time while printing a number as part of another operation.

You can leverage the java_home helper binary on OS X for what you're looking for.

To list all versions of installed JDK:

$ /usr/libexec/java_home -V
Matching Java Virtual Machines (2):
    1.8.0_51, x86_64:   "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_51.jdk/Contents/Home
    1.7.0_79, x86_64:   "Java SE 7" /Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home

To request the JAVA_HOME path of a specific JDK version, you can do:

$ /usr/libexec/java_home -v 1.7
/Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home

$ /usr/libexec/java_home -v 1.8
/Library/Java/JavaVirtualMachines/jdk1.8.0_51.jdk/Contents/Home

You could take advantage of the above commands in your script like this:

REQUESTED_JAVA_VERSION="1.7"
if POSSIBLE_JAVA_HOME="$(/usr/libexec/java_home -v $REQUESTED_JAVA_VERSION 2>/dev/null)"; then
    # Do this if you want to export JAVA_HOME
    export JAVA_HOME="$POSSIBLE_JAVA_HOME"
    echo "Java SDK is installed"
else
    echo "Did not find any installed JDK for version $REQUESTED_JAVA_VERSION"
fi

You might be able to do if-else and check for multiple different versions of java as well.

If you prefer XML output, java_home also has a -X option to output in XML.

$ /usr/libexec/java_home --help
Usage: java_home [options...]
    Returns the path to a Java home directory from the current user's settings.

Options:
    [-v/--version   <version>]       Filter Java versions in the "JVMVersion" form 1.X(+ or *).
    [-a/--arch      <architecture>]  Filter JVMs matching architecture (i386, x86_64, etc).
    [-d/--datamodel <datamodel>]     Filter JVMs capable of -d32 or -d64
    [-t/--task      <task>]          Use the JVM list for a specific task (Applets, WebStart, BundledApp, JNI, or CommandLine)
    [-F/--failfast]                  Fail when filters return no JVMs, do not continue with default.
    [   --exec      <command> ...]   Execute the $JAVA_HOME/bin/<command> with the remaining arguments.
    [-R/--request]                   Request installation of a Java Runtime if not installed.
    [-X/--xml]                       Print full JVM list and additional data as XML plist.
    [-V/--verbose]                   Print full JVM list with architectures.
    [-h/--help]                      This usage information.

this worked for me, with kotlin

fun formatToDigitalClock(miliSeconds: Long): String {
        val hours = TimeUnit.MILLISECONDS.toHours(miliSeconds).toInt() % 24
        val minutes = TimeUnit.MILLISECONDS.toMinutes(miliSeconds).toInt() % 60
        val seconds = TimeUnit.MILLISECONDS.toSeconds(miliSeconds).toInt() % 60
        return when {
            hours > 0 -> String.format("%d:%02d:%02d", hours, minutes, seconds)
            minutes > 0 -> String.format("%02d:%02d", minutes, seconds)
            seconds > 0 -> String.format("00:%02d", seconds)
            else -> {
                "00:00"
            }
        }
    }

Put it this way

where ("R"."TIME_STAMP">=TO_DATE ('03-02-2013 00:00:00', 'DD-MM-YYYY HH24:MI:SS')
   AND "R"."TIME_STAMP"<=TO_DATE ('09-02-2013 23:59:59', 'DD-MM-YYYY HH24:MI:SS')) 

Where R is table name.
TIME_STAMP is FieldName in Table R.

Or you can always map over an iterator, without the need to build an intermediate list:

>>> _ = map(sys.stdout.write, (x for x in string.letters if x in (y for y in "BigMan on campus")))

It can be done!!!!!!

There is someone who did it.

Enjoy :)

Below is an adaptation of previous code for using under PyQt5 and Matplotlib 2.0. There are a number of small changes: structure of PyQt submodules, other submodule from matplotlib, deprecated method has been replaced...

import sys
from PyQt5.QtWidgets import QDialog, QApplication, QPushButton, QVBoxLayout

from matplotlib.backends.backend_qt5agg import FigureCanvasQTAgg as FigureCanvas
from matplotlib.backends.backend_qt5agg import NavigationToolbar2QT as NavigationToolbar
import matplotlib.pyplot as plt

import random

class Window(QDialog):
    def __init__(self, parent=None):
        super(Window, self).__init__(parent)

        # a figure instance to plot on
        self.figure = plt.figure()

        # this is the Canvas Widget that displays the `figure`
        # it takes the `figure` instance as a parameter to __init__
        self.canvas = FigureCanvas(self.figure)

        # this is the Navigation widget
        # it takes the Canvas widget and a parent
        self.toolbar = NavigationToolbar(self.canvas, self)

        # Just some button connected to `plot` method
        self.button = QPushButton('Plot')
        self.button.clicked.connect(self.plot)

        # set the layout
        layout = QVBoxLayout()
        layout.addWidget(self.toolbar)
        layout.addWidget(self.canvas)
        layout.addWidget(self.button)
        self.setLayout(layout)

    def plot(self):
        ''' plot some random stuff '''
        # random data
        data = [random.random() for i in range(10)]

        # instead of ax.hold(False)
        self.figure.clear()

        # create an axis
        ax = self.figure.add_subplot(111)

        # discards the old graph
        # ax.hold(False) # deprecated, see above

        # plot data
        ax.plot(data, '*-')

        # refresh canvas
        self.canvas.draw()

if __name__ == '__main__':
    app = QApplication(sys.argv)

    main = Window()
    main.show()

    sys.exit(app.exec_())

That's a fine solution. I just wanted to add

set -e

as a rudimentary error mechanism. It will immediately stop your script if a simple command fails. I think this should have been the default behavior: since such errors almost always signify something unexpected, it is not really 'sane' to keep executing the following commands.

Small change to @Chris Lang answer. if you want Monday as the first day use this.

Date.prototype.GetFirstDayOfWeek = function() {
    return (new Date(this.setDate(this.getDate() - this.getDay()+ (this.getDay() == 0 ? -6:1) )));
}
Date.prototype.GetLastDayOfWeek = function() {
    return (new Date(this.setDate(this.getDate() - this.getDay() +7)));
}

var today = new Date();

alert(today.GetFirstDayOfWeek());

alert(today.GetLastDayOfWeek());

Thaks @Chris Lang

Use List.indexOf(). This will give you the first match when there are multiple duplicates.

Exporting without default means it's a "named export". You can have multiple named exports in a single file. So if you do this,

class Template {}
class AnotherTemplate {}

export { Template, AnotherTemplate }

then you have to import these exports using their exact names. So to use these components in another file you'd have to do,

import {Template, AnotherTemplate} from './components/templates'

Alternatively if you export as the default export like this,

export default class Template {}

Then in another file you import the default export without using the {}, like this,

import Template from './components/templates'

There can only be one default export per file. In React it's a convention to export one component from a file, and to export it is as the default export.

You're free to rename the default export as you import it,

import TheTemplate from './components/templates'

And you can import default and named exports at the same time,

import Template,{AnotherTemplate} from './components/templates'

I don't see an obvious problem with the above.

It's possible your ldap.conf is being overridden, but the command-line options will take precedence, ldapsearch will ignore BINDDN in the main ldap.conf, so the only parameter that could be wrong is the URI. (The order is ETCDIR/ldap.conf then ~/ldaprc or ~/.ldaprc and then ldaprc in the current directory, though there environment variables which can influence this too, see man ldapconf.)

Try an explicit URI:

ldapsearch -x -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base -H ldap://localhost

or prevent defaults with:

LDAPNOINIT=1 ldapsearch -x -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base

If that doesn't work, then some troubleshooting (you'll probably need the full path to the slapd binary for these):

• make sure your slapd.conf is being used and is correct (as root)

  slapd -T test -f slapd.conf -d 65535

  You may have a left-over or default slapd.d configuration directory which takes preference over your slapd.conf (unless you specify your config explicitly with -f, slapd.conf is officially deprecated in OpenLDAP-2.4). If you don't get several pages of output then your binaries were built without debug support.

• stop OpenLDAP, then manually start slapd in a separate terminal/console with debug enabled (as root, ^C to quit)

  slapd -h ldap://localhost -d 481

  then retry the search and see if you can spot the problem (there will be a lot of schema noise in the start of the output unfortunately). (Note: running slapd without the -u/-g options can change file ownerships which can cause problems, you should usually use those options, probably -u ldap -g ldap )

• if debug is enabled, then try also

  ldapsearch -v -d 63 -W -D 'cn=Manager,dc=example,dc=com' -b "" -s base

Note: I am not sure if this is correct but you can give it a try and see if this works.

There is a unslick method which de-initializes the carousel, so you might try using that before re-initializing it.

$.ajax({
    type: 'get',
    url: '/public/index',
    dataType: 'script',
    data: data_send,
    success: function() {
        $('.skills_section').unslick();  // destroy the previous instance
        slickCarousel();
      }
});

Hope this helps.

This is a specific issue for Windows Vista, 7, 8 (and presumably newer).

User Account Control (UAC) is a feature in Windows that can help you stay in control of your computer by informing you when a program makes a change that requires administrator-level permission. UAC works by adjusting the permission level of your user account.

This is applied mostly to C:\Program Files. You may have noticed sometimes, that some applications can see files in C:\Program Files that does not exist there. You know why? Windows now tend to have "C:\Program Files" folder customized for every user. For example, old applications store config files (like .ini) in the same folder where the executable files are stored. In the good old days all users had the same configurations for such apps. In nowadays Windows stores configs in the special folder tied to the user account. Thus, now different users may have different configs while application still think that config files are in the same folder with the executables.

XAMPP does not like to have different config for different users. In fact it is not a config file for XAMPP, it is folders where you keep your projects and databases. The idea of XAMPP is to make projects same for all users. This is a source of a conflict with Windows.

All you need is to avoid installing XAMPP into C:\Program Files. Thus XAMPP will always use the original files for all users and there would be no confusion.

I recommend to install XAMPP into the special folder in root directory like in C:\XAMPP. But before you choose the folder you need to click on this warning message.

Google fix this mistake with the build tools version: 23.0.3 Now zipalign is packaged properly, and everything works fine.

This produces the same results as using __year, __month, and __day and seems to work for me:

YourModel.objects.filter(your_datetime_field__startswith=datetime.date(2009,8,22))

You should use getFullYear() instead of getYear(). getYear() returns the actual year minus 1900 (and so is fairly useless).

Thus a date marking exactly one year from the present moment would be:

var oneYearFromNow = new Date();
oneYearFromNow.setFullYear(oneYearFromNow.getFullYear() + 1);

Note that the date will be adjusted if you do that on February 29.

Similarly, you can get a date that's a month from now via getMonth() and setMonth(). You don't have to worry about "rolling over" from the current year into the next year if you do it in December; the date will be adjusted automatically. Same goes for day-of-month via getDate() and setDate().

In your HTML you have set a "base" tag:

<base href="http://www.cyclistinsuranceaustralia.com.au/">

1. Delete that line from your HTML if you don't need it. This should make the fonts work when viewed from http://cyclistinsuranceaustralia.com.au.
2. You'll probably need to redirect http://www.cyclistinsuranceaustralia.com.au to http://cyclistinsuranceaustralia.com.au

Apache Http Client APIs are very commonly used for calling HTTP Rest services.

Here is one of example of consuming HTTP GET call.

import java.io.IOException;
import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpUriRequest;
import org.apache.http.impl.client.HttpClientBuilder;

public class CallHTTPGetService {

public static void main(String[] args) throws ClientProtocolException, IOException {


    HttpClient client = HttpClientBuilder.create().build();
    HttpUriRequest httpUriRequest = new HttpGet("URL");

    HttpResponse response = client.execute(httpUriRequest);
    System.out.println(response);

}
}

Use following maven dependency if using Maven project.

Alternatives to Native Support of Java Operator Overloading

Since Java doesn't have operator overloading, here are some alternatives you can look into:

1. Use another language. Both Groovy and Scala have operator overloading, and are based on Java.
2. Use java-oo, a plugin that enables operator overloading in Java. Note that it is NOT platform independent. Also, it has many issues, and is not compatible with the latest releases of Java (i.e. Java 10). (Original StackOverflow Source)
3. Use JNI, Java Native Interface, or alternatives. This allows you to write C or C++ (maybe others?) methods for use in Java. Of course this is also NOT platform independent.

If anyone is aware of others, please comment, and I will add it to this list.

Yes, it could be with the actual encoding of the file, probably unicode. Try UTF-8 as that is the most common form of unicode encoding. Otherwise if the file ASCII then standard ASCII encoding should work.

If you want to see the array as an array, you can say

alert(JSON.stringify(aCustomers));

instead of all those document.writes.

http://jsfiddle.net/5b2eb/

However, if you want to display them cleanly, one per line, in your popup, do this:

alert(aCustomers.join("\n"));

http://jsfiddle.net/5b2eb/1/

Restart Netbeans & it solved my problem.

you'll have to pre-scale that drawable before you use it as a background

you can add a condition to the after_update like so:

class SomeModel < ActiveRecord::Base
  after_update :send_notification, if: :published_changed?

  ...
end

there's no need to add a condition within the send_notification method itself.

Use with caution (because of eval()):

function strToJson(str) {
  eval("var x = " + str + ";");
  return JSON.stringify(x);
}

call as:

var str = "{ hello: 'world', places: ['Africa', 'America', 'Asia', 'Australia'] }";
alert( strToJson(str) );

I found a nice implementation of the server side pre-rev-prop-change hook at the svnforum: https://www.svnforum.org/forum/opensource-subversion-forums/scripts-contributions/8571-pre-revprop-change-shell-script-allows-commiters-to-change-own-log-within-x-hours

It implements

• user checking, that is only own commit messages can be edited.
• Svn admin override; admin can edit anything.
• time stamp comparison: only commits that are younger than certain time can be edited

Grab it from there and edit at will. I'd rather not copy it here since I am not the original author and there is no copyright notice that would allow me to do it.

In your mysql command line do the following:

mysql> SHOW GLOBAL VARIABLES LIKE '%timestamp%';
+---------------------------------+-------+
| Variable_name                   | Value |
+---------------------------------+-------+
| explicit_defaults_for_timestamp | OFF   |
| log_timestamps                  | UTC   |
+---------------------------------+-------+
2 rows in set (0.01 sec)

mysql> SET GLOBAL explicit_defaults_for_timestamp = 1;
Query OK, 0 rows affected (0.00 sec)

mysql> SHOW GLOBAL VARIABLES LIKE '%timestamp%';
+---------------------------------+-------+
| Variable_name                   | Value |
+---------------------------------+-------+
| explicit_defaults_for_timestamp | ON    |
| log_timestamps                  | UTC   |

2 rows in set (0.00 sec)

This is not actually a problem with the function being "void", but a problem with the function parameters. I think it's just g++ giving an unhelpful error message.

EDIT: As in the accepted answer, the fix is to use std::string instead of just string.

Expanding on the answers given above, just ensure you set maxZoom option when initializing the map object.

Faced the same problem, I was not able to run wordpress docker container with mysql version 8 as its default authentication mechanism is caching_sha2_password instead of mysql_native_password.

In order to fix this problem we must reset default authentication mechanism to mysql_native_password.

Find my.cnf file in your mysql installation, usually on a linux machine it is at the following location - /etc/mysql

Edit my.cnf file and add following line just under heading [mysqld]

default_authentication_plugin= mysql_native_password

Save the file then log into mysql command line using root user

run command FLUSH PRIVILEGES;

Here is my solution if you don't want to mess with additional libraries or edit your code manually. I created this Jupyter notebook to go over all java files and comment out all the Log messages. Not perfect but it got the job done for me.

Why is this answer still getting upvotes?

Per Mikaël Mayer's answer, this is no longer a problem, and my answer is obsolete (go() now returns 30 after mucking with the console). This was fixed in July 2013, according to the bug report linked above in gabrielmaldi's comment. It alarms me that I'm still getting upvotes - makes me think the upvoter doesn't understand either the question or my answer.

I'll leave my original answer here for historical reasons, but go upvote Mikaël's answer instead.

The trick is that you can't change a local variable directly, but you can modify the properties of an object. You can also modify the value of a global variable:

var g_n = 0;
function go()
{
    var n = 0;
    var o = { n: 0 };
    return g_n + n + o.n;  // breakpoint here
}

console:

> g_n = 10
  10
> g_n
  10
> n = 10
  10
> n
  0
> o.n = 10
  10
> o.n
  10

Check the result of go() after setting the breakpoint and running those calls in the console, and you'll find that the result is 20, rather than 0 (but sadly, not 30).

There are a number of JavaScript obfuscation tools that are freely available; however, I think it's important to note that it is difficult to obfuscate JavaScript to the point where it cannot be reverse-engineered.

To that end, there are several options that I've used to some degree overtime:

• YUI Compressor. Yahoo!'s JavaScript compressor does a good job of condensing the code that will improve its load time. There is a small level of obfuscation that works relatively well. Essentially, Compressor will change function names, remove white space, and modify local variables. This is what I use most often. This is an open-source Java-based tool.

• JSMin is a tool written by Douglas Crockford that seeks to minify your JavaScript source. In Crockford's own words, "JSMin does not obfuscate, but it does uglify." It's primary goal is to minify the size of your source for faster loading in browsers.

• Free JavaScript Obfuscator. This is a web-based tool that attempts to obfuscate your code by actually encoding it. I think that the trade-offs of its form of encoding (or obfuscation) could come at the cost of filesize; however, that's a matter of personal preference.

I don't know that much about batch files but couldn't you have a pre-made batch file copied from the home directory to the path you have that would return a list of the names of the files then use that name?

Here is a link I think might be helpful in making the pre-made batch file.

http://www.ericphelps.com/batch/lists/filelist.htm

you can use numpy.argsort

or you can do:

test =  [2,3,1,4,5]
idxs = list(zip(*sorted([(val, i) for i, val in enumerate(test)])))[1]

zip will rearange the list so that the first element is test and the second is the idxs.

INSERT statements that use VALUES syntax can insert multiple rows. To do this, include multiple lists of column values, each enclosed within parentheses and separated by commas.

Example:

INSERT INTO tbl_name
    (a,b,c)
VALUES
    (1,2,3),
    (4,5,6),
    (7,8,9);

Another reason Singletons are an anti-pattern is that if written according to recommendations, with private constructor, they are very hard to subclass and configure to use in certain unit tests. Would be required in maintaining legacy code, for example.

I don't know why

cfg_name_unique NOT LIKE '%categories%' 

still returns those two values, but maybe exclude them explicit:

SELECT *

No Gemfile.lock means:

• new contributors cannot run tests because weird things fail, so they won't contribute or get failing PRs ... bad first experience.
• you cannot go back to a x year old project and fix a bug without having to update/rewrite the project if you lost your local Gemfile.lock

-> Always check in Gemfile.lock, make travis delete it if you want to be extra thorough https://grosser.it/2015/08/14/check-in-your-gemfile-lock/

my two cents for VS 2017:

I can confirm it works in stdafx.h both in these styles:

a)

#pragma once
#define _CRT_SECURE_NO_WARNINGS 1 
#define _WINSOCK_DEPRECATED_NO_WARNINGS 1 

b)

#define _CRT_SECURE_NO_WARNINGS 1 
#define _WINSOCK_DEPRECATED_NO_WARNINGS 1 
#pragma once

(I have added another define for MSDN network calls..) Of course I do prefer a).

I can confirm that: #define _CRT_SECURE_NO_WARNINGS (without a value) DOES NOT WORK.

PS the real point is to put these defines BEFORE declarations of functions, i.e. before *.h

Open the Servers view -> double click tomcat -> drop down the Timeouts section

There you can increase the startup time for each particular server.

In Anjuta, go to the Build menu, then Configure Project. In the Configure Options box, add:

LDFLAGS='-lpthread'

Hope it'll help somebody too...

Yes you can do that.

Here is an example:

a{
    background:IMAGE-URL;
    display:block;
    height:IMAGE-HEIGHT;
    width:IMAGE-WIDTH;
}

Of course you can modify the above example to your need. The important thing is to make it appear as a block (display:block) or an inline block (display:inline-block).

You are getting close!

# Find all of the text between paragraph tags and strip out the html
page = soup.find('p').getText()

Using find (as you've noticed) stops after finding one result. You need find_all if you want all the paragraphs. If the pages are formatted consistently ( just looked over one), you could also use something like

soup.find('div',{'id':'ctl00_PlaceHolderMain_RichHtmlField1__ControlWrapper_RichHtmlField'})

to zero in on the body of the article.

Use group_concat() function of mysql.

SELECT GROUP_CONCAT(id) FROM table_level where parent_id=4 GROUP BY parent_id;

It'll give you concatenated string like :

In "The C++ Programming Language, Third Edition by Bjarne Stroustrup", the nº1 must-read C++ book, he uses *.h. So I assume the best practice is to use *.h.

However, *.hpp is fine as well!

What is the difference between char array vs char pointer in C?

C99 N1256 draft

There are two different uses of character string literals:

1. Initialize char[]:

   char c[] = "abc";      
   

   This is "more magic", and described at 6.7.8/14 "Initialization":

   An array of character type may be initialized by a character string literal, optionally enclosed in braces. Successive characters of the character string literal (including the terminating null character if there is room or if the array is of unknown size) initialize the elements of the array.

   So this is just a shortcut for:

   char c[] = {'a', 'b', 'c', '\0'};
   

   Like any other regular array, c can be modified.

2. Everywhere else: it generates an:

   • unnamed
   • array of char What is the type of string literals in C and C++?
   • with static storage
   • that gives UB (undefined behavior) if modified

   So when you write:

   char *c = "abc";
   

   This is similar to:

   /* __unnamed is magic because modifying it gives UB. */
   static char __unnamed[] = "abc";
   char *c = __unnamed;
   

   Note the implicit cast from char[] to char *, which is always legal.

   Then if you modify c[0], you also modify __unnamed, which is UB.

   This is documented at 6.4.5 "String literals":

   5 In translation phase 7, a byte or code of value zero is appended to each multibyte character sequence that results from a string literal or literals. The multibyte character sequence is then used to initialize an array of static storage duration and length just sufficient to contain the sequence. For character string literals, the array elements have type char, and are initialized with the individual bytes of the multibyte character sequence [...]

   6 It is unspecified whether these arrays are distinct provided their elements have the appropriate values. If the program attempts to modify such an array, the behavior is undefined.

6.7.8/32 "Initialization" gives a direct example:

EXAMPLE 8: The declaration

char s[] = "abc", t[3] = "abc";

defines "plain" char array objects s and t whose elements are initialized with character string literals.

This declaration is identical to

char s[] = { 'a', 'b', 'c', '\0' },
t[] = { 'a', 'b', 'c' };

The contents of the arrays are modifiable. On the other hand, the declaration

char *p = "abc";

defines p with type "pointer to char" and initializes it to point to an object with type "array of char" with length 4 whose elements are initialized with a character string literal. If an attempt is made to use p to modify the contents of the array, the behavior is undefined.

GCC 4.8 x86-64 ELF implementation

Program:

#include <stdio.h>

int main(void) {
    char *s = "abc";
    printf("%s\n", s);
    return 0;
}

Compile and decompile:

gcc -ggdb -std=c99 -c main.c
objdump -Sr main.o

Output contains:

 char *s = "abc";
8:  48 c7 45 f8 00 00 00    movq   $0x0,-0x8(%rbp)
f:  00 
        c: R_X86_64_32S .rodata

Conclusion: GCC stores char* it in .rodata section, not in .text.

If we do the same for char[]:

 char s[] = "abc";

we obtain:

17:   c7 45 f0 61 62 63 00    movl   $0x636261,-0x10(%rbp)

so it gets stored in the stack (relative to %rbp).

Note however that the default linker script puts .rodata and .text in the same segment, which has execute but no write permission. This can be observed with:

readelf -l a.out

which contains:

 Section to Segment mapping:
  Segment Sections...
   02     .text .rodata

There are many links that lets you know how to handle post values from checkboxes in php. Look at this link: http://www.html-form-guide.com/php-form/php-form-checkbox.html

Single check box

HTML code:

<form action="checkbox-form.php" method="post">
    Do you need wheelchair access?
    <input type="checkbox" name="formWheelchair" value="Yes" />
    <input type="submit" name="formSubmit" value="Submit" />
</form>

PHP Code:

<?php

if (isset($_POST['formWheelchair']) && $_POST['formWheelchair'] == 'Yes') 
{
    echo "Need wheelchair access.";
}
else
{
    echo "Do not Need wheelchair access.";
}    

?>

Check box group

<form action="checkbox-form.php" method="post">
    Which buildings do you want access to?<br />
    <input type="checkbox" name="formDoor[]" value="A" />Acorn Building<br />
    <input type="checkbox" name="formDoor[]" value="B" />Brown Hall<br />
    <input type="checkbox" name="formDoor[]" value="C" />Carnegie Complex<br />
    <input type="checkbox" name="formDoor[]" value="D" />Drake Commons<br />
    <input type="checkbox" name="formDoor[]" value="E" />Elliot House

    <input type="submit" name="formSubmit" value="Submit" />
 /form>

<?php
  $aDoor = $_POST['formDoor'];
  if(empty($aDoor)) 
  {
    echo("You didn't select any buildings.");
  } 
  else
  {
    $N = count($aDoor);

    echo("You selected $N door(s): ");
    for($i=0; $i < $N; $i++)
    {
      echo($aDoor[$i] . " ");
    }
  }
?>

At first you must consider that if your activity which I called A extends another activity (B) and in both of

them you want to use onbackpressed function then every code you have in B runs in A too. So if you want to separate these you should separate them. It means that A should not extend B , then you can have onbackpressed separately for each of them.

This seems like a common misunderstanding. In Oracle's JVM, the permanent generation is not part of the heap. It's a separate space for class definitions and related data. In Java 6 and earlier, interned strings were also stored in the permanent generation. In Java 7, interned strings are stored in the main object heap.

Here is a good post on permanent generation.

I like the descriptions given for each space in Oracle's guide on JConsole:

For the HotSpot Java VM, the memory pools for serial garbage collection are the following.

• Eden Space (heap): The pool from which memory is initially allocated for most objects.
• Survivor Space (heap): The pool containing objects that have survived the garbage collection of the Eden space.
• Tenured Generation (heap): The pool containing objects that have existed for some time in the survivor space.
• Permanent Generation (non-heap): The pool containing all the reflective data of the virtual machine itself, such as class and method objects. With Java VMs that use class data sharing, this generation is divided into read-only and read-write areas.
• Code Cache (non-heap): The HotSpot Java VM also includes a code cache, containing memory that is used for compilation and storage of native code.

Java uses generational garbage collection. This means that if you have an object foo (which is an instance of some class), the more garbage collection events it survives (if there are still references to it), the further it gets promoted. It starts in the young generation (which itself is divided into multiple spaces - Eden and Survivor) and would eventually end up in the tenured generation if it survived long enough.

NOTE: Confirmed with Access 2003, don't know about earlier versions.

For a query in an MDB you can right-click in the query designer (anywhere in the empty space where the tables are), select Properties from the context menu, and enter text in the Description property.

You're limited to 256 characters, but it's better than nothing.

You can get at the description programatically with something like this:

Dim db As Database
Dim qry As QueryDef

Set db = Application.CurrentDb
Set qry = db.QueryDefs("myQuery")

Debug.Print qry.Properties("Description")

Your data may not be what you expect -- it seems you're expecting, but not getting, floats.

A simple solution to figuring out where this occurs would be to add a try/except to the for-loop:

for i in range(0,N):
    w=f[i].split()
    l1=w[1:8]
    l2=w[8:15]
    try:
      list1=[float(x) for x in l1]
      list2=[float(x) for x in l2]
    except ValueError, e:
      # report the error in some way that is helpful -- maybe print out i
    result=stats.ttest_ind(list1,list2)
    print result[1]

ULs don't have a name attribute, but you can reference the ul by tag name.

Try replacing line 3 in your script with this:

var sub = cat.getElementsByTagName("UL");

Without having to repeat the array (e.g. perfect for one-liners):

[1, 2, 3, 4].then { |a| a.sum.to_f / a.size }

There are also the %<% and %<=% comparison operators in the TeachingDemos package which allow you to do this like:

sum( 2 %<% x %<% 5 )
sum( 2 %<=% x %<=% 5 )

which gives the same results as:

sum( 2 < x & x < 5 )
sum( 2 <= x & x <= 5 )

Which is better is probably more a matter of personal preference.

You can choose between the following two methods to set the text of an Entry widget. For the examples, assume imported library import tkinter as tk and root window root = tk.Tk().

• Method A: Use delete and insert

  Widget Entry provides methods delete and insert which can be used to set its text to a new value. First, you'll have to remove any former, old text from Entry with delete which needs the positions where to start and end the deletion. Since we want to remove the full old text, we start at 0 and end at wherever the end currently is. We can access that value via END. Afterwards the Entry is empty and we can insert new_text at position 0.

  entry = tk.Entry(root)
  new_text = "Example text"
  entry.delete(0, tk.END)
  entry.insert(0, new_text)
  

• Method B: Use StringVar

  You have to create a new StringVar object called entry_text in the example. Also, your Entry widget has to be created with keyword argument textvariable. Afterwards, every time you change entry_text with set, the text will automatically show up in the Entry widget.

  entry_text = tk.StringVar()
  entry = tk.Entry(root, textvariable=entry_text)
  new_text = "Example text"
  entry_text.set(new_text)
  

• Complete working example which contains both methods to set the text via Button:

  This window

  

  is generated by the following complete working example:

  import tkinter as tk
  
  def button_1_click():
      # define new text (you can modify this to your needs!)
      new_text = "Button 1 clicked!"
      # delete content from position 0 to end
      entry.delete(0, tk.END)
      # insert new_text at position 0
      entry.insert(0, new_text)
  
  def button_2_click():
      # define new text (you can modify this to your needs!)
      new_text = "Button 2 clicked!"
      # set connected text variable to new_text
      entry_text.set(new_text)
  
  root = tk.Tk()
  
  entry_text = tk.StringVar()
  entry = tk.Entry(root, textvariable=entry_text)
  
  button_1 = tk.Button(root, text="Button 1", command=button_1_click)
  button_2 = tk.Button(root, text="Button 2", command=button_2_click)
  
  entry.pack(side=tk.TOP)
  button_1.pack(side=tk.LEFT)
  button_2.pack(side=tk.LEFT)
  
  root.mainloop()
  

If you want to do it safely, you may want to use http://docs.python.org/library/ast.html#ast.literal_eval

from this answer: Python "safe" eval (string to bool/int/float/None/string)

It might not do math, but you could parse the math operators and then operate on safely evaluated terms.

Simply closing Android Studio (and emulator) then re-opening fixed it for me. Once I ran the app again, the apk re-installed successfully and app ran properly.

Have you tried using the "auto-fill" in Excel?

If you have an entire column of items you put the formula in the first cell, make sure you get the result you desire and then you can do the copy/paste, or use auto fill which is an option that sits on the bottom right corner of the cell.

You go to that corner in the cell and once your cursor changes to a "+", you can double-click on it and it should populate all the way down to the last entry (as long as there are no populated cells, that is).

Another way, say in CentOS, is:

You could add another empty layout below that one and set them both to have the same layout weight. They should get 50% of the space each.

Major advantage :

ViewHolder is not available by default in ListView. We will be creating explicitly inside the getView(). RecyclerView has inbuilt Viewholder.

• com => domain
• something => company name
• something => Main package name

For example: com.paresh.mainpackage

Companies use their reversed Internet domain name to begin their package names—for example, com.example.mypackage for a package named mypackage created by a programmer at example.com. This information i have found at http://download.oracle.com/javase/tutorial/java/package/namingpkgs.html

You could achieve that simply by wrapping the image by a <div> and adding overflow: hidden to that element:

<div class="img-wrapper">
    <img src="..." />
</div>

.img-wrapper {
    display: inline-block; /* change the default display type to inline-block */
    overflow: hidden;      /* hide the overflow */
}

WORKING DEMO.

Also it's worth noting that <img> element (like the other inline elements) sits on its baseline by default. And there would be a 4~5px gap at the bottom of the image.

That vertical gap belongs to the reserved space of descenders like: g j p q y. You could fix the alignment issue by adding vertical-align property to the image with a value other than baseline.

Additionally for a better user experience, you could add transition to the images.

Thus we'll end up with the following:

.img-wrapper img {
    transition: all .2s ease;
    vertical-align: middle;
}

UPDATED DEMO.

Implicit waits are used to provide a default waiting time between each consecutive test step/command across the entire test script. Thus, subsequent test step would only execute when the specified amount of time have elapsed after executing the previous test step/command.

Explicit waits are used to halt the execution till the time a particular condition is met or the maximum time has elapsed. Unlike Implicit waits, Explicit waits are applied for a particular instance only.

You can try converting your image from tiff to PNG, here is how to do it:

import com.sun.media.jai.codec.ImageCodec;
import com.sun.media.jai.codec.ImageDecoder;
import com.sun.media.jai.codec.ImageEncoder;
import com.sun.media.jai.codec.PNGEncodeParam;
import com.sun.media.jai.codec.TIFFDecodeParam;
import java.awt.image.RenderedImage;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.InputStream;
import javaxt.io.Image;

public class ImgConvTiffToPng {

    public static byte[] convert(byte[] tiff) throws Exception {

        byte[] out = new byte[0];
        InputStream inputStream = new ByteArrayInputStream(tiff);

        TIFFDecodeParam param = null;

        ImageDecoder dec = ImageCodec.createImageDecoder("tiff", inputStream, param);
        RenderedImage op = dec.decodeAsRenderedImage(0);

        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();

        PNGEncodeParam jpgparam = null;
        ImageEncoder en = ImageCodec.createImageEncoder("png", outputStream, jpgparam);
        en.encode(op);
        outputStream = (ByteArrayOutputStream) en.getOutputStream();
        out = outputStream.toByteArray();
        outputStream.flush();
        outputStream.close();

        return out;

    }

You have to consider the Turkish I problem when comparing characters/ lowercasing / uppercasing:

I suggest to convert to String and use toLowerCase with invariant culture (in most cases at least).

public final static Locale InvariantLocale = new Locale(Empty, Empty, Empty); str.toLowerCase(InvariantLocale)

See similar C# string.ToLower() and string.ToLowerInvariant()

Note: Don't use String.equalsIgnoreCase http://nikolajlindberg.blogspot.co.il/2008/03/beware-of-java-comparing-turkish.html

I Know this question was aked 3 years ago, but I just had the same problem, and what solved it was instead of putting:

 while (i.hasNext()) {
    // code goes here 
}

I did one iteration at the start, and then checked for condition using:

do {
   // code goes here
} while (i.hasNext());

I hope this will help some people at some stage.

If you use nano with a language like python (as in your example) it's also a good idea to convert tabs to spaces.

Edit your ~/.nanorc file (or create it) and add:

set tabsize 4
set tabstospaces

If you already got a file with tabs and want to convert them to spaces i recommend the expandcommand (shell):

expand -4 input.py > output.py

Alternatively:

 var byteStr = Convert.ToBase64String(bytes);

iisexpress program is responsible for that.

Initital add & commit worked like a charm. I guess it's just a matter of understanding Git's methodology of managing a project within the repository.

After that I've managed to push my data straight-away with no hassle.

Crescent Fresh's answer highly-voted answer is misleading. Though his warnings are invalid, there are other limitations that he doesn't address.

First, the reasoning in Crescent's "Caveats:" paragraph doesn't make sense. The explanation implies that coding "a bunch of if (error instanceof MyError) else ..." is somehow burdensome or verbose compared to multiple catch statements. Multiple instanceof statements in a single catch block are just as concise as multiple catch statements-- clean and concise code without any tricks. This is a great way to emulate Java's great throwable-subtype-specific error handling.

WRT "appears the message property of the subclass does not get set", that is not the case if you use a properly constructed Error subclass. To make your own ErrorX Error subclass, just copy the code block beginning with "var MyError =", changing the one word "MyError" to "ErrorX". (If you want to add custom methods to your subclass, follow the sample text).

The real and significant limitation of JavaScript error subclassing is that for JavaScript implementations or debuggers that track and report on stack trace and location-of-instantiation, like FireFox, a location in your own Error subclass implementation will be recorded as the instantiation point of the class, whereas if you used a direct Error, it would be the location where you ran "new Error(...)"). IE users would probably never notice, but users of Fire Bug on FF will see useless file name and line number values reported alongside these Errors, and will have to drill down on the stack trace to element #1 to find the real instantiation location.

"jdbc:mysql://localhost"

From the oracle docs..

jdbc:mysql://[host][,failoverhost...]
[:port]/[database]
[?propertyName1][=propertyValue1]
[&propertyName2][=propertyValue2]

host:port is the host name and port number of the computer hosting your database. If not specified, the default values of host and port are 127.0.0.1 and 3306, respectively.

database is the name of the database to connect to. If not specified, a connection is made with no default database.

failover is the name of a standby database (MySQL Connector/J supports failover).

propertyName=propertyValue represents an optional, ampersand-separated list of properties. These attributes enable you to instruct MySQL Connector/J to perform various tasks.

It is possible to solve this problem using notepad++ by replacing Tabs with 4 Spaces:

1. Choose Search -> Find... or press Ctrl + F
2. Select the Replace tab
3. In the box named Search Mode choose Extended(\n, \r, \t, \0, \x...)
4. In the field Find what : write \t
5. In the field Replace with : press Space 4 times. Be sure that there is nothing else in this field.
6. Click on the button Replace All

string[] is an array (vector) of strings string is just a string (a list/array of characters)

Depending on how you want to convert this, the canonical answer could be:

string[] -> string

return String.Join(" ", myStringArray);

string -> string[]

return new []{ myString };

The fields of your object have in turn their fields, some of which do not implement Serializable. In your case the offending class is TransformGroup. How to solve it?

• if the class is yours, make it Serializable
• if the class is 3rd party, but you don't need it in the serialized form, mark the field as transient
• if you need its data and it's third party, consider other means of serialization, like JSON, XML, BSON, MessagePack, etc. where you can get 3rd party objects serialized without modifying their definitions.

The problem occurs when your custom class has for property some other class e.g. "Bitmap". What I made is to change the property field from "private Bitmap photo" to "private transient Bitmap photo". However the image is empty after I getIntent() in the receiver activity. Because of this I passed the custom class to the intent and also I've created a byte array from the image and pass it separatly to the intent:

selectedItem is my custom object and getPlacePhoto is his method to get image. I've already set it before and now I just get it first than convert it and pass it separatly:

 Bitmap image = selectedItem.getPlacePhoto();
 image.compress(Bitmap.CompressFormat.PNG, 100, stream);
 byte[] byteArray = stream.toByteArray();
 Intent intent = new Intent(YourPresentActivity.this, 
 TheReceiverActivity.class);
 intent.putExtra("selectedItem", selectedItem);                 
 intent.putExtra("image", byteArray);
 startActivity(intent);            

`

Then in the receiver activity I get my object and the image as byte array, decode the image and set it to my object as photo property.

 Intent intent = getIntent();
 selectedItem = (ListItem) intent.getSerializableExtra("selectedItem");
 byte[] byteArray = getIntent().getByteArrayExtra("image");
 Bitmap image = BitmapFactory.decodeByteArray(byteArray, 0, 
 byteArray.length);
 selectedItem.setPhoto(image);

I know its Too late But I hope it will work new comers Try This Its Working ... :D

The PGOPTIONS environment variable may be used to achieve this in a flexible way.

In an Unix shell:

PGOPTIONS="--search_path=my_schema_01" psql -d myDataBase -a -f myInsertFile.sql

If there are several invocations in the script or sub-shells that need the same options, it's simpler to set PGOPTIONS only once and export it.

PGOPTIONS="--search_path=my_schema_01"
export PGOPTIONS

psql -d somebase
psql -d someotherbase
...

or invoke the top-level shell script with PGOPTIONS set from the outside

PGOPTIONS="--search_path=my_schema_01"  ./my-upgrade-script.sh

In Windows CMD environment, set PGOPTIONS=value should work the same.

I'm posting this answer for anyone using C# that wants a fully functional, well-tested answer that demonstrates using query instead of scan. In particular, this answer handles more than 1MB size of items to count.

        public async Task<int> GetAvailableCount(string pool_type, string pool_key)
    {
        var queryRequest = new QueryRequest
        {
            TableName = PoolsDb.TableName,
            ConsistentRead = true,
            Select = Select.COUNT,
            KeyConditionExpression = "pool_type_plus_pool_key = :type_plus_key",
            ExpressionAttributeValues = new Dictionary<string, AttributeValue> {
                {":type_plus_key", new AttributeValue { S =  pool_type + pool_key }}
            },
        };
        var t0 = DateTime.UtcNow;
        var result = await Client.QueryAsync(queryRequest);
        var count = result.Count;
        var iter = 0;
        while ( result.LastEvaluatedKey != null && result.LastEvaluatedKey.Values.Count > 0) 
        {
            iter++;
            var lastkey = result.LastEvaluatedKey.Values.ToList()[0].S;
            _logger.LogDebug($"GetAvailableCount {pool_type}-{pool_key} iteration {iter} instance key {lastkey}");
            queryRequest.ExclusiveStartKey = result.LastEvaluatedKey;
            result = await Client.QueryAsync(queryRequest);
            count += result.Count;
        }
        _logger.LogDebug($"GetAvailableCount {pool_type}-{pool_key} returned {count} after {iter} iterations in {(DateTime.UtcNow - t0).TotalMilliseconds} ms.");
        return count;
    }
}

You are facing this problem because when you are posting your forms so after reloading your dropdown is unable to find data in viewbag. So make sure that code you are using in get method while retrieving your data from db or from static list, copy paste that code into post verb as well..

Happy Coding :)

The error "client denied by server configuration" generally means that somewhere in your configuration are Allow from and Deny from directives that are preventing access. Read the mod_authz_host documentation for more details.

You should be able to solve this in your VirtualHost by adding something like:

<Location />
  Allow from all
  Order Deny,Allow
</Location>

Or alternatively with a Directory directive:

<Directory "D:/Devel/matysart/matysart_dev1">
  Allow from all
  Order Deny,Allow
</Directory>

Some investigation of your Apache configuration files will probably turn up default restrictions on the default DocumentRoot.

extension String {

    func convertDatetring_TopreferredFormat(currentFormat: String, toFormat : String) ->  String {
        let dateFormator = DateFormatter()
        dateFormator.dateFormat = currentFormat
        let resultDate = dateFormator.date(from: self)
        dateFormator.dateFormat = toFormat
        return dateFormator.string(from: resultDate!)
    }

}

Call from your view controller file as below.

"your_date_string".convertDatetring_TopreferredFormat(currentFormat: "yyyy-MM-dd HH:mm:ss.s", toFormat: "dd-MMM-yyyy h:mm a")

Here is an original solution with the framework Danf (you don't need any code for this kind of things, only some config):

// config/common/config/sequences.js

'use strict';

module.exports = {
    executeMySyncQueries: {
        operations: [
            {
                order: 0,
                service: 'danf:http.router',
                method: 'follow',
                arguments: [
                    'www.example.com/api_1.php',
                    'GET'
                ],
                scope: 'response1'
            },
            {
                order: 1,
                service: 'danf:http.router',
                method: 'follow',
                arguments: [
                    'www.example.com/api_2.php',
                    'GET'
                ],
                scope: 'response2'
            },
            {
                order: 2,
                service: 'danf:http.router',
                method: 'follow',
                arguments: [
                    'www.example.com/api_3.php',
                    'GET'
                ],
                scope: 'response3'
            }
        ]
    }
};

Use the same order value for operations you want to be executed in parallel.

If you want to be even shorter, you can use a collection process:

// config/common/config/sequences.js

'use strict';

module.exports = {
    executeMySyncQueries: {
        operations: [
            {
                service: 'danf:http.router',
                method: 'follow',
                // Process the operation on each item
                // of the following collection.
                collection: {
                    // Define the input collection.
                    input: [
                        'www.example.com/api_1.php',
                        'www.example.com/api_2.php',
                        'www.example.com/api_3.php'
                    ],
                    // Define the async method used.
                    // You can specify any collection method
                    // of the async lib.
                    // '--' is a shorcut for 'forEachOfSeries'
                    // which is an execution in series.
                    method: '--'
                },
                arguments: [
                    // Resolve reference '@@.@@' in the context
                    // of the input item.
                    '@@.@@',
                    'GET'
                ],
                // Set the responses in the property 'responses'
                // of the stream.
                scope: 'responses'
            }
        ]
    }
};

Take a look at the overview of the framework for more informations.

In any case, your code will generate invalid markup: You shouldn't wrap block contents in a link. tags don't work like this. If you want this effect you should use js or create an absolutely positioned link above the content (z-index). More on this here: Make a div into a link.

You should make sure to validate your code when it renders: http://validator.w3.org

There are many paths through your code whereby your variables are not initialized, which is why the compiler complains.

Specifically, you are not validating the user input for creditPlan - if the user enters a value of anything else than "0","1","2" or "3", then none of the branches indicated will be executed (and creditPlan will not be defaulted to zero as per your user prompt).

As others have mentioned, the compiler error can be avoided by either a default initialization of all derived variables before the branches are checked, OR ensuring that at least one of the branches is executed (viz, mutual exclusivity of the branches, with a fall through else statement).

I would however like to point out other potential improvements:

• Validate user input before you trust it for use in your code.
• Model the parameters as a whole - there are several properties and calculations applicable to each plan.
• Use more appropriate types for data. e.g. CreditPlan appears to have a finite domain and is better suited to an enumeration or Dictionary than a string. Financial data and percentages should always be modelled as decimal, not double to avoid rounding issues, and 'status' appears to be a boolean.
• DRY up repetitive code. The calculation, monthlyCharge = balance * annualRate * (1/12)) is common to more than one branch. For maintenance reasons, do not duplicate this code.
• Possibly more advanced, but note that Functions are now first class citizens of C#, so you can assign a function or lambda as a property, field or parameter!.

e.g. here is an alternative representation of your model:

    // Keep all Credit Plan parameters together in a model
    public class CreditPlan
    {
        public Func<decimal, decimal, decimal> MonthlyCharge { get; set; }
        public decimal AnnualRate { get; set; }
        public Func<bool, Decimal> LateFee { get; set; }
    }

    // DRY up repeated calculations
    static private decimal StandardMonthlyCharge(decimal balance, decimal annualRate)
    { 
       return balance * annualRate / 12;
    }

    public static Dictionary<int, CreditPlan> CreditPlans = new Dictionary<int, CreditPlan>
    {
        { 0, new CreditPlan
            {
                AnnualRate = .35M, 
                LateFee = _ => 0.0M, 
                MonthlyCharge = StandardMonthlyCharge
            }
        },
        { 1, new CreditPlan
            {
                AnnualRate = .30M, 
                LateFee = late => late ? 0 : 25.0M,
                MonthlyCharge = StandardMonthlyCharge
            }
        },
        { 2, new CreditPlan
            {
                AnnualRate = .20M, 
                LateFee = late => late ? 0 : 35.0M,
                MonthlyCharge = (balance, annualRate) => balance > 100 
                    ? balance * annualRate / 12
                    : 0
            }
        },
        { 3, new CreditPlan
            {
                AnnualRate = .15M, 
                LateFee = _ => 0.0M,
                MonthlyCharge = (balance, annualRate) => balance > 500 
                    ? (balance - 500) * annualRate / 12
                    : 0
            }
        }
    };

You need to set ulimit -c. If you have 0 for this parameter a coredump file is not created. So do this: ulimit -c unlimited and check if everything is correct ulimit -a. The coredump file is created when an application has done for example something inappropriate. The name of the file on my system is core.<process-pid-here>.

Like bruno said, you're better configuring it yourself. Here's how I do it. Start by creating a properties file (/etc/myapp/config.properties).

javax.net.ssl.keyStore = /etc/myapp/keyStore
javax.net.ssl.keyStorePassword = 123456

Then load the properties to your environment from your code. This makes your application configurable.

FileInputStream propFile = new FileInputStream("/etc/myapp/config.properties");
Properties p = new Properties(System.getProperties());
p.load(propFile);
System.setProperties(p);

Does the --lock-tables=false option work?

According to the man page, if you are dumping InnoDB tables you can use the --single-transaction option:

--lock-tables, -l

Lock all tables before dumping them. The tables are locked with READ
LOCAL to allow concurrent inserts in the case of MyISAM tables. For
transactional tables such as InnoDB and BDB, --single-transaction is
a much better option, because it does not need to lock the tables at
all.

For innodb DB:

mysqldump --single-transaction=TRUE -u username -p DB

Using .apply() with a lambda conversion function also works in this case:

total_rows['ColumnID'] = total_rows['ColumnID'].apply(lambda x: str(x))

For entire dataframes you can use .applymap(). (but in any case probably .astype() is faster)

One way to do that is to set the cascade option on you "One" side of relationship:

class Employee {
   // 

   @OneToMany(cascade = {CascadeType.PERSIST})
   private Set<Vehicles> vehicles = new HashSet<Vehicles>();

   //
}

by this, when you call

Employee savedEmployee = employeeDao.persistOrMerge(newEmployee);

it will save the vehicles too.

First, you need to create a personal access token (PAT). This is described here: https://help.github.com/articles/creating-an-access-token-for-command-line-use/

Laughably, the article tells you how to create it, but gives absolutely no clue what to do with it. After about an hour of trawling documentation and Stack Overflow, I finally found the answer:

$ git clone https://github.com/user-or-organisation/myrepo.git
Username: <my-username>
Password: <my-personal-access-token>

I was actually forced to enable two-factor authentication by company policy while I was working remotely and still had local changes, so in fact it was not clone I needed, but push. I read in lots of places that I needed to delete and recreate the remote, but in fact my normal push command worked exactly the same as the clone above, and the remote did not change:

$ git push https://github.com/user-or-organisation/myrepo.git
Username: <my-username>
Password: <my-personal-access-token>

_{(@YMHuang put me on the right track with the documentation link.)}

I just ran into this problem with VirtualBox 5.1 on Windows 8. It turns out the problem was with the Kaspersky virus protection I have installed. It added the "Kaspersky Anti-Virus NDIS 6 Filter" on the host-only adapter on the windows side. When I disabled that filter the VM started properly:

• Go to ezwinports, https://sourceforge.net/projects/ezwinports/files/

• Download make-4.2.1-without-guile-w32-bin.zip (get the version without guile)

• Extract zip
• Copy the contents to C:\ProgramFiles\Git\mingw64\ merging the folders, but do NOT overwrite/replace any exisiting files.

Finally found a solution with a docker-compose method. Since docker-compose file format 2.1 you can define healthchecks.

I did it in a example project you need to install at least docker 1.12.0+. I also needed to extend the rabbitmq-management Dockerfile, because curl isn't installed on the official image.

Now I test if the management page of the rabbitmq-container is available. If curl finishes with exitcode 0 the container app (python pika) will be started and publish a message to hello queue. Its now working (output).

docker-compose (version 2.1):

version: '2.1'

services:
  app:
    build: app/.
    depends_on:
      rabbit:
        condition: service_healthy
    links: 
        - rabbit

  rabbit:
    build: rabbitmq/.
    ports: 
        - "15672:15672"
        - "5672:5672"
    healthcheck:
        test: ["CMD", "curl", "-f", "http://localhost:15672"]
        interval: 30s
        timeout: 10s
        retries: 5

output:

rabbit_1  | =INFO REPORT==== 25-Jan-2017::14:44:21 ===
rabbit_1  | closing AMQP connection <0.718.0> (172.18.0.3:36590 -> 172.18.0.2:5672)
app_1     |  [x] Sent 'Hello World!'
healthcheckcompose_app_1 exited with code 0

Dockerfile (rabbitmq + curl):

FROM rabbitmq:3-management
RUN apt-get update
RUN apt-get install -y curl 
EXPOSE 4369 5671 5672 25672 15671 15672

Version 3 no longer supports the condition form of depends_on. So i moved from depends_on to restart on-failure. Now my app container will restart 2-3 times until it is working, but it is still a docker-compose feature without overwriting the entrypoint.

docker-compose (version 3):

version: "3"

services:

  rabbitmq: # login guest:guest
    image: rabbitmq:management
    ports:
    - "4369:4369"
    - "5671:5671"
    - "5672:5672"
    - "25672:25672"
    - "15671:15671"
    - "15672:15672"
    healthcheck:
        test: ["CMD", "curl", "-f", "http://localhost:15672"]
        interval: 30s
        timeout: 10s
        retries: 5

  app:
    build: ./app/
    environment:
      - HOSTNAMERABBIT=rabbitmq
    restart: on-failure
    depends_on:
      - rabbitmq
    links: 
        - rabbitmq

If your page is refreshed on submitting - yes, but only through the querystring: http://www.bloggingdeveloper.com/post/JavaScript-QueryString-ParseGet-QueryString-with-Client-Side-JavaScript.aspx (You must use method "GET" then). Else, you can return its value from the php script.

onBackPressed() is supported since: API Level 5

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if ((keyCode == KeyEvent.KEYCODE_BACK)) {
        onBackPressed();
    }
}

@Override
public void onBackPressed() {
    //this is only needed if you have specific things
    //that you want to do when the user presses the back button.
    /* your specific things...*/
    super.onBackPressed();   
}

 Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:"+198+","+1+","+1)); 
             startActivity(callIntent);

for multiple ordered call

This is used to DTMF calling systems. If call is drop then, you should pass more " , " between numbers.

If you really just want a random value from the available key range, use random.choice on the dictionary's values (converted to list form, if Python 3).

>>> from random import choice
>>> d = {1: 'a', 2: 'b', 3: 'c'}
>>>> choice(list(d.values()))

int myArray[10] = { 5, 5, 5, 5, 5, 5, 5, 5, 5, 5 }; // All elements of myArray are 5
int myArray[10] = { 0 };    // Will initialize all elements to 0
int myArray[10] = { 5 };    // Will initialize myArray[0] to 5 and other elements to 0
static int myArray[10]; // Will initialize all elements to 0
/************************************************************************************/
int myArray[10];// This will declare and define (allocate memory) but won’t initialize
int i;  // Loop variable
for (i = 0; i < 10; ++i) // Using for loop we are initializing
{
    myArray[i] = 5;
}
/************************************************************************************/
int myArray[10] = {[0 ... 9] = 5}; // This works only in GCC

         bool breakInnerLoop=false
        for(int i=0;i<=10;i++)
        {
          for(int J=0;i<=10;i++)
          {
              if(i<=j)
                {
                    breakInnerLoop=true;
                    break;
                }
          }
            if(breakInnerLoop)
            {
            continue
            }
        }

I also had a -215 error. I thought imshow was the issue, but when I changed imread to read in a non-existent file I got no error there. So I put the image file in the working folder and added cv2.waitKey(0) and it worked.

Try this:

line.Replace("\",\"", ";")

The almighty switch works well here:

'one
two
three' > file

$regex = '^t'

switch -regex -file file { 
  $regex { "line is $_" } 
}

Output:

line is two
line is three

Another easy way is to use:

mysqladmin debug 

This dumps a lot of information (including locks) to the error log.

The accepted answer by Adam (flex: 1 1 0) works perfectly for flexbox containers whose width is either fixed, or determined by an ancestor. Situations where you want the children to fit the container.

However, you may have a situation where you want the container to fit the children, with the children equally sized based on the largest child. You can make a flexbox container fit its children by either:

• setting position: absolute and not setting width or right, or
• place it inside a wrapper with display: inline-block

For such flexbox containers, the accepted answer does NOT work, the children are not sized equally. I presume that this is a limitation of flexbox, since it behaves the same in Chrome, Firefox and Safari.

The solution is to use a grid instead of a flexbox.

Demo: https://codepen.io/brettdonald/pen/oRpORG

<p>Normal scenario — flexbox where the children adjust to fit the container — and the children are made equal size by setting {flex: 1 1 0}</p>

<div id="div0">
  <div>
    Flexbox
  </div>
  <div>
    Width determined by viewport
  </div>
  <div>
    All child elements are equal size with {flex: 1 1 0}
  </div>
</div>

<p>Now we want to have the container fit the children, but still have the children all equally sized, based on the largest child. We can see that {flex: 1 1 0} has no effect.</p>

<div class="wrap-inline-block">
<div id="div1">
  <div>
    Flexbox
  </div>
  <div>
    Inside inline-block
  </div>
  <div>
    We want all children to be the size of this text
  </div>
</div>
</div>

<div id="div2">
  <div>
    Flexbox
  </div>
  <div>
    Absolutely positioned
  </div>
  <div>
    We want all children to be the size of this text
  </div>
</div>

<br><br><br><br><br><br>
<p>So let's try a grid instead. Aha! That's what we want!</p>

<div class="wrap-inline-block">
<div id="div3">
  <div>
    Grid
  </div>
  <div>
    Inside inline-block
  </div>
  <div>
    We want all children to be the size of this text
  </div>
</div>
</div>

<div id="div4">
  <div>
    Grid
  </div>
  <div>
    Absolutely positioned
  </div>
  <div>
    We want all children to be the size of this text
  </div>

One thing I've not seen anyone mention: the JSON file must have one line specifying the index the next line belongs to, for every line of the "pure" JSON file.

I.E.

{"index":{"_index":"shakespeare","_type":"act","_id":0}}
{"line_id":1,"play_name":"Henry IV","speech_number":"","line_number":"","speaker":"","text_entry":"ACT I"}

Without that, nothing works, and it won't tell you why

You can use also util methods mentioned in this blog: Getting cell witdth and height from excel with Apache POI. It can solve your problem.

Copy & paste from that blog:

static public class PixelUtil {

    public static final short EXCEL_COLUMN_WIDTH_FACTOR = 256;
    public static final short EXCEL_ROW_HEIGHT_FACTOR = 20;
    public static final int UNIT_OFFSET_LENGTH = 7;
    public static final int[] UNIT_OFFSET_MAP = new int[] { 0, 36, 73, 109, 146, 182, 219 };

    public static short pixel2WidthUnits(int pxs) {
        short widthUnits = (short) (EXCEL_COLUMN_WIDTH_FACTOR * (pxs / UNIT_OFFSET_LENGTH));
        widthUnits += UNIT_OFFSET_MAP[(pxs % UNIT_OFFSET_LENGTH)];
        return widthUnits;
    }

    public static int widthUnits2Pixel(short widthUnits) {
        int pixels = (widthUnits / EXCEL_COLUMN_WIDTH_FACTOR) * UNIT_OFFSET_LENGTH;
        int offsetWidthUnits = widthUnits % EXCEL_COLUMN_WIDTH_FACTOR;
        pixels += Math.floor((float) offsetWidthUnits / ((float) EXCEL_COLUMN_WIDTH_FACTOR / UNIT_OFFSET_LENGTH));
        return pixels;
    }

    public static int heightUnits2Pixel(short heightUnits) {
        int pixels = (heightUnits / EXCEL_ROW_HEIGHT_FACTOR);
        int offsetWidthUnits = heightUnits % EXCEL_ROW_HEIGHT_FACTOR;
        pixels += Math.floor((float) offsetWidthUnits / ((float) EXCEL_ROW_HEIGHT_FACTOR / UNIT_OFFSET_LENGTH));
        return pixels;
    }
}

So when you want to get cell width and height you can use this to get value in pixel, values are approximately.

PixelUtil.heightUnits2Pixel((short) row.getHeight())
PixelUtil.widthUnits2Pixel((short) sh.getColumnWidth(columnIndex));

use this after initialisation

$('.form_datetime').datetimepicker('update', new Date());

This alternate approach with filtering for format counts all available grub kernel modules:

ls -l /boot/grub/*.mod | wc -l

try this single command to both delete and insert the data:

DELETE MyTable
    OUTPUT DELETED.Col1, DELETED.COl2,...
        INTO MyBackupTable

working sample:

--set up the tables
DECLARE @MyTable table (col1 int, col2 varchar(5))
DECLARE @MyBackupTable table (col1 int, col2 varchar(5))
INSERT INTO @MyTable VALUES (1,'A')
INSERT INTO @MyTable VALUES (2,'B')
INSERT INTO @MyTable VALUES (3,'C')
INSERT INTO @MyTable VALUES (4,'D')

--single command that does the delete and inserts
DELETE @MyTable
    OUTPUT DELETED.Col1, DELETED.COl2
        INTO @MyBackupTable

--show both tables final values
select * from @MyTable
select * from @MyBackupTable

OUTPUT:

(1 row(s) affected)

(1 row(s) affected)

(1 row(s) affected)

(1 row(s) affected)

(4 row(s) affected)
col1        col2
----------- -----

(0 row(s) affected)

col1        col2
----------- -----
1           A
2           B
3           C
4           D

(4 row(s) affected)

This will search all the related files in current and sub directories, calculating their line count separately as well as totally:

find . -name "*.wanted" | xargs wc -l

In fragment guide FragmentList example you can find:

@Override
public void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    outState.putInt("curChoice", mCurCheckPosition);
}

Which you can use later like this:

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    if (savedInstanceState != null) {
        // Restore last state for checked position.
        mCurCheckPosition = savedInstanceState.getInt("curChoice", 0);
    }
}

I'm a beginner in Fragments but it seems like solution of your problem ;) OnActivityCreated is invoked after fragment returns from back stack.

<div 
 style="-moz-user-select: none; -webkit-user-select: none; -ms-user-select:none; user-select:none;-o-user-select:none;" 
 unselectable="on"
 onselectstart="return false;" 
 onmousedown="return false;">
    Blabla
</div>

You don't need --header "Content-Length: $LENGTH".

curl --request POST --data-binary "@template_entry.xml" $URL

Note that GET request does not support content body widely.

Also remember that POST request have 2 different coding schema. This is first form:

  $ nc -l -p 6666 &
  $ curl  --request POST --data-binary "@README" http://localhost:6666

POST / HTTP/1.1
User-Agent: curl/7.21.0 (x86_64-pc-linux-gnu) libcurl/7.21.0 OpenSSL/0.9.8o zlib/1.2.3.4 libidn/1.15 libssh2/1.2.6

You probably request this:

-F/--form name=content
           (HTTP) This lets curl emulate a filled-in form in
              which a user has pressed the submit button. This
              causes curl to POST data using the Content- Type
              multipart/form-data according to RFC2388. This
              enables uploading of binary files etc. To force the
              'content' part to be a file, prefix the file name
              with an @ sign. To just get the content part from a
              file, prefix the file name with the symbol <. The
              difference between @ and < is then that @ makes a
              file get attached in the post as a file upload,
              while the < makes a text field and just get the
              contents for that text field from a file.

POD stands for Plain Old Data - that is, a class (whether defined with the keyword struct or the keyword class) without constructors, destructors and virtual members functions. Wikipedia's article on POD goes into a bit more detail and defines it as:

A Plain Old Data Structure in C++ is an aggregate class that contains only PODS as members, has no user-defined destructor, no user-defined copy assignment operator, and no nonstatic members of pointer-to-member type.

Greater detail can be found in this answer for C++98/03. C++11 changed the rules surrounding POD, relaxing them greatly, thus necessitating a follow-up answer here.

Take a look at dGrid:

I agree that users will NEVER, EVER need to view millions of rows of data all at once, but dGrid can display them quickly (a screenful at a time).

Don't boil the ocean to make a cup of tea.

There is a project on CodeProject that makes it simple to convert an XML file to SQL Script. It uses XSLT. You could probably modify it to generate the DDL too.

And See this question too : Generating SQL using XML and XSLT

SELECT DATEADD(m,DATEDIFF(m,0,GETDATE())-1,0) AS PreviousMonthStart

SELECT DATEADD(ms,-2,DATEADD(month, DATEDIFF(month, 0, GETDATE()), 0)) AS PreviousMonthEnd

[OOT]

A bit OOT, but this question is the most closest topic with my question.

Here is an example if you want to show Event where ALL participant meet certain requirement. Let's say, event where ALL the participant has fully paid. So, it WILL NOT return events which having one or more participants that haven't fully paid .

Simply use the whereDoesntHave of the others 2 statuses.

Let's say the statuses are haven't paid at all [eq:1], paid some of it [eq:2], and fully paid [eq:3]

Event::whereDoesntHave('participants', function ($query) {
   return $query->whereRaw('payment = 1 or payment = 2');
})->get();

Semantic Difference

According to HTML 5.2:

When specified on an element, [the hidden attribute] indicates that the element is not yet, or is no longer, directly relevant to the page’s current state, or that it is being used to declare content to be reused by other parts of the page as opposed to being directly accessed by the user.

Examples include a tab list where some panels are not exposed, or a log-in screen that goes away after a user logs in. I like to call these things “temporally relevant” i.e. they are relevant based on timing.

On the other hand, ARIA 1.1 says:

[The aria-hidden state] indicates whether an element is exposed to the accessibility API.

In other words, elements with aria-hidden="true" are removed from the accessibility tree, which most assistive technology honors, and elements with aria-hidden="false" will definitely be exposed to the tree. Elements without the aria-hidden attribute are in the "undefined (default)" state, which means user agents should expose it to the tree based on its rendering. E.g. a user agent may decide to remove it if its text color matches its background color.

Now let’s compare semantics. It’s appropriate to use hidden, but not aria-hidden, for an element that is not yet “temporally relevant”, but that might become relevant in the future (in which case you would use dynamic scripts to remove the hidden attribute). Conversely, it’s appropriate to use aria-hidden, but not hidden, on an element that is always relevant, but with which you don’t want to clutter the accessibility API; such elements might include “visual flair”, like icons and/or imagery that are not essential for the user to consume.

Effective Difference

The semantics have predictable effects in browsers/user agents. The reason I make a distinction is that user agent behavior is recommended, but not required by the specifications.

The hidden attribute should hide an element from all presentations, including printers and screen readers (assuming these devices honor the HTML specs). If you want to remove an element from the accessibility tree as well as visual media, hidden would do the trick. However, do not use hidden just because you want this effect. Ask yourself if hidden is semantically correct first (see above). If hidden is not semantically correct, but you still want to visually hide the element, you can use other techniques such as CSS.

Elements with aria-hidden="true" are not exposed to the accessibility tree, so for example, screen readers won’t announce them. This technique should be used carefully, as it will provide different experiences to different users: accessible user agents won’t announce/render them, but they are still rendered on visual agents. This can be a good thing when done correctly, but it has the potential to be abused.

Syntactic Difference

Lastly, there is a difference in syntax between the two attributes.

hidden is a boolean attribute, meaning if the attribute is present it is true—regardless of whatever value it might have—and if the attribute is absent it is false. For the true case, the best practice is to either use no value at all (<div hidden>...</div>), or the empty string value (<div hidden="">...</div>). I would not recommend hidden="true" because someone reading/updating your code might infer that hidden="false" would have the opposite effect, which is simply incorrect.

aria-hidden, by contrast, is an enumerated attribute, allowing one of a finite list of values. If the aria-hidden attribute is present, its value must be either "true" or "false". If you want the "undefined (default)" state, remove the attribute altogether.

Compression algorithms almost always have some form of space overhead, which means that they are only effective when compressing data which is sufficiently large that the overhead is smaller than the amount of saved space.

Compressing a string which is only 20 characters long is not too easy, and it is not always possible. If you have repetition, Huffman Coding or simple run-length encoding might be able to compress, but probably not by very much.

You need to wrap button click handler to match the pattern

public void klik(object sender, EventArgs e)

Try:

String[] val = { "helloword1", "orange", "grape", "pear" };
String sep = "";
string stringToCheck = "word1";

bool match = String.Join(sep,val).Contains(stringToCheck);
bool anothermatch = val.Any(s => s.Contains(stringToCheck));

if you use Vuejs, just make it by vue-shortkey plugin, everything will be simple

We have lot of answers to this question. This answer may be helpful in some scenarios If you want to ignore the null values you can use the NOT_NULL in class level. as below

@JsonInclude(Include.NON_NULL)
class Foo
{
  String bar;
}

Some times you may need to ignore the empty values such as you may have initialized the arrayList but there is no elements in that list.In that time using NOT_EMPTY annotation to ignore those empty value fields

@JsonInclude(Include.NON_EMPTY)
class Foo
{
  String bar;
}

JpaRepository also extends QueryByExampleExecutor. So you don't even need to define custom methods on your interface:

public interface UserRepository extends JpaRepository<User, Long> {
    // no need of custom method
}

And then query like:

User probe = new User();
u.setName = "John";
long count = repo.count(Example.of(probe));

I just followed a method that we would usually follow in java script. To convert object to string and then check whether they are null.

var obj = new Object();
var objStr = obj.ToString();
if (!string.IsNullOrEmpty(objStr)){
  // code as per your needs
}

my solution only works for the next cases: if you are mistaking a multidimensaional array into a single one

$json = file_get_contents('url_json'); //get the json
$objhigher=json_decode($json); //converts to an object
$objlower = $objhigher[0]; // if the json response its multidimensional this lowers it
echo "<pre>"; //box for code
print_r($objlower); //prints the object with all key and values
echo $objlower->access_token; //prints the variable

i know that the answer was has already been answered but for those who came here looking for something i hope this can help you

I like this nice one line solution

getent passwd username > /dev/null 2&>1 && echo yes || echo no

and in script:

#!/bin/bash

if [ "$1" != "" ]; then
        getent passwd $1 > /dev/null 2&>1 && (echo yes; exit 0) || (echo no; exit 2)
else
        echo "missing username"
        exit -1
fi

use:

[mrfish@yoda ~]$ ./u_exists.sh root
yes
[mrfish@yoda ~]$ echo $?
0

[mrfish@yoda ~]$ ./u_exists.sh
missing username
[mrfish@yoda ~]$ echo $?
255

[mrfish@yoda ~]$ ./u_exists.sh aaa
no
[mrfish@indegy ~]$ echo $?
2

I looked at this excellent info and then wondered, since

1. i have python2, python3 and IPython all installed,
2. i have PyCharm installed,
3. PyCharm uses IPython for its Python Console,

if PyCharm would use

1. IPython-py2 when Menu>File>Settings>Project>Project Interpreter == py2 AND
2. IPython-py3 when Menu>File>Settings>Project>Project Interpreter == py3

ANSWER: Yes!

P.S. i have Python Launcher for Windows installed as well.

Creating a resource is generally mapped to POST, and that should return the location of the new resource; for example, in a Rails scaffold a CREATE will redirect to the SHOW for the newly created resource. The same approach might make sense for updating (PUT), but that's less of a convention; an update need only indicate success. A delete probably only needs to indicate success as well; if you wanted to redirect, returning the LIST of resources probably makes the most sense.

Success can be indicated by HTTP_OK, yes.

The only hard-and-fast rule in what I've said above is that a CREATE should return the location of the new resource. That seems like a no-brainer to me; it makes perfect sense that the client will need to be able to access the new item.

I had the similar issue. The problem was in the passwords: the Keystore and private key used different passwords. (KeyStore explorer was used)

After creating Keystore with the same password as private key had the issue was resolved.

In MS Excel, first save your workbook as a Macro Enabled file then go to the Developper Tab and click on Visual Basic. Copy and paste this code in the "ThisWorkbook" Excel Objects. Replace the 2 values of G = and C= by the number of the column containing the values being referenced.

In your case, if the number of the column named "File No" is the first column (namely column 1), replace G=6 by G=1 and C=6 by C-1. Finally click on Macro, Select and Run it. Voila! Works like a charm.

Sub color()
    Dim g As Long
    Dim c As Integer
    Dim colorIt As Boolean

    g = 6
    c = 6
    colorIt = True

    Do While Cells(g, c) <> ""
        test_value = Cells(g, c)
        Do While Cells(g, c) = test_value
            If colorIt Then
                Cells(g, c).EntireRow.Select
                Selection.Interior.ColorIndex = 15
            Else
                Cells(g, c).EntireRow.Select
                Selection.Interior.ColorIndex = x1None
            End If
            g = g + 1
        Loop
        colorIt = Not (colorIt)
    Loop
End Sub

$("#myAudioElement")[0].play();

It doesn't work with $("#myAudioElement").play() like you would expect. The official reason is that incorporating it into jQuery would add a play() method to every single element, which would cause unnecessary overhead. So instead you have to refer to it by its position in the array of DOM elements that you're retrieving with $("#myAudioElement"), aka 0.

This quote is from a bug that was submitted about it, which was closed as "feature/wontfix":

To do that we'd need to add a jQuery method name for each DOM element method name. And of course that method would do nothing for non-media elements so it doesn't seem like it would be worth the extra bytes it would take.

Either serialize:

$postvalue=array("a","b","c");
<input type="hidden" name="result" value="<?php echo serialize($postvalue); ?>">

on receive: unserialize($_POST['result'])

Or implode:

$postvalue=array("a","b","c");
<input type="hidden" name="result" value="<?php echo implode(',', $postvalue); ?>">

On receive: explode(',', $_POST['result'])

Setting the image using picture.ImageLocation() works fine, but you are using a relative path. Check your path against the location of the .exe after it is built.

For example, if your .exe is located at:

<project folder>/bin/Debug/app.exe

The image would have to be at:

<project folder>/bin/Image/1.jpg

Of course, you could just set the image at design-time (the Image property on the PictureBox property sheet).

If you must set it at run-time, one way to make sure you know the location of the image is to add the image file to your project. For example, add a new folder to your project, name it Image. Right-click the folder, choose "Add existing item" and browse to your image (be sure the file filter is set to show image files). After adding the image, in the property sheet set the Copy to Output Directory to Copy if newer.

At this point the image file will be copied when you build the application and you can use

picture.ImageLocation = @"Image\1.jpg"; 

You can't bind an event to the element before it exists, so you should do it in the onload event:

<html>
<head>
<script type="text/javascript">

window.onload = function() {

  document.getElementById('foo').addEventListener('click', function (e) {
    var img = document.createElement('img');
    img.setAttribute('src', 'http://blog.stackoverflow.com/wp-content/uploads/stackoverflow-logo-300.png');
    e.target.appendChild(img);
  });

};

</script>
</head>
<body>
<img id="foo" src="http://soulsnatcher.bplaced.net/LDRYh.jpg" alt="unfinished bingo card" />
</body>
</html>

Change the checkboxes so that the name includes the index inside the brackets:

<input type="checkbox" class="checkbox_veh" id="checkbox_addveh<?php echo $i; ?>" <?php if ($vehicle_feature[$i]->check) echo "checked"; ?> name="feature[<?php echo $i; ?>]" value="<?php echo $vehicle_feature[$i]->id; ?>"> 

The checkboxes that aren't checked are never submitted. The boxes that are checked get submitted, but they get numbered consecutively from 0, and won't have the same indexes as the other corresponding input fields.

Found that setting the secure property in Session_Start is sufficient, as recommended in MSDN blog "Securing Session ID: ASP/ASP.NET" with some augmentation.

    protected void Session_Start(Object sender, EventArgs e)
    {
        SessionStateSection sessionState = 
 (SessionStateSection)ConfigurationManager.GetSection("system.web/sessionState");
        string sidCookieName = sessionState.CookieName;

        if (Request.Cookies[sidCookieName] != null)
        {
            HttpCookie sidCookie = Response.Cookies[sidCookieName];
            sidCookie.Value = Session.SessionID;
            sidCookie.HttpOnly = true;
            sidCookie.Secure = true;
            sidCookie.Path = "/";
        }
    }

First of all, I recommend checking some standard things like:

• login as the correct user in your system,
• have the right private key in the right location in your system,
• try to connect with the correct username, hostname, and port,
• have the public key in the right location (and for the right user) in the external server,
• restarted the ssh service at your computer:

service ssh restart

(or in another way depending on how you manage services in your system...)

It was enough for me.

From Wikipedia:

In PHP, the scope resolution operator is also called Paamayim Nekudotayim (Hebrew: ?????? ?????????), which means “double colon” in Hebrew.

The name "Paamayim Nekudotayim" was introduced in the Israeli-developed Zend Engine 0.5 used in PHP 3. Although it has been confusing to many developers who do not speak Hebrew, it is still being used in PHP 5, as in this sample error message:

$ php -r :: Parse error: syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM

As of PHP 5.4, error messages concerning the scope resolution operator still include this name, but have clarified its meaning somewhat:

$ php -r :: Parse error: syntax error, unexpected '::' (T_PAAMAYIM_NEKUDOTAYIM)

From the official PHP documentation:

The Scope Resolution Operator (also called Paamayim Nekudotayim) or in simpler terms, the double colon, is a token that allows access to static, constant, and overridden properties or methods of a class.

When referencing these items from outside the class definition, use the name of the class.

As of PHP 5.3.0, it's possible to reference the class using a variable. The variable's value can not be a keyword (e.g. self, parent and static).

Paamayim Nekudotayim would, at first, seem like a strange choice for naming a double-colon. However, while writing the Zend Engine 0.5 (which powers PHP 3), that's what the Zend team decided to call it. It actually does mean double-colon - in Hebrew!

This would print the files in those directories line by line.

array=(ww/* ee/* qq/*)
printf "%s\n" "${array[@]}"

First : Identity Specification Just : "No" >> Save Database Execute Project

After then : Identity Specification Just : "YES" >> Save Database Execute Project

When you get the error message, you have the option to click on "Debug": this will lead you to the line where the error occurred. The Dark Canuck seems to be right, and I guess the error occurs on the line:

Sheets("Sheet1").protect Password:="btfd"

because most probably the "Sheet1" does not exist. However, if you say "It works fine, but when I save the file I get the message: run-time error '9': subscription out of range" it makes me think the error occurs on the second line:

ActiveWorkbook.Save

Could you please check this by pressing the Debug button first? And most important, as Gordon Bell says, why are you using a macro to protect a workbook?

git ls-tree --full-tree -r HEAD and git ls-files return all files at once. For a large project with hundreds or thousands of files, and if you are interested in a particular file/directory, you may find more convenient to explore specific directories. You can do it by obtaining the ID/SHA-1 of the directory that you want to explore and then use git cat-file -p [ID/SHA-1 of directory]. For example:

git cat-file -p 14032aabd85b43a058cfc7025dd4fa9dd325ea97
100644 blob b93a4953fff68df523aa7656497ee339d6026d64    glyphicons-halflings-regular.eot
100644 blob 94fb5490a2ed10b2c69a4a567a4fd2e4f706d841    glyphicons-halflings-regular.svg
100644 blob 1413fc609ab6f21774de0cb7e01360095584f65b    glyphicons-halflings-regular.ttf
100644 blob 9e612858f802245ddcbf59788a0db942224bab35    glyphicons-halflings-regular.woff
100644 blob 64539b54c3751a6d9adb44c8e3a45ba5a73b77f0    glyphicons-halflings-regular.woff2

In the example above, 14032aabd85b43a058cfc7025dd4fa9dd325ea97 is the ID/SHA-1 of the directory that I wanted to explore. In this case, the result was that four files within that directory were being tracked by my Git repo. If the directory had additional files, it would mean those extra files were not being tracked. You can add files using git add <file>... of course.

in (backend.php) be sure to include include

session_start();

There's no reason to new (on the heap) when you can allocate on the stack (unless for some reason you've got a small stack and want to use the heap.

You might want to consider using a shared_ptr (or one of its variants) from the standard library if you do want to allocate on the heap. That'll handle doing the delete for you once all references to the shared_ptr have gone out of existance.

/var/www/html is just the default root folder of the web server. You can change that to be whatever folder you want by editing your apache.conf file (usually located in /etc/apache/conf) and changing the DocumentRoot attribute (see http://httpd.apache.org/docs/current/mod/core.html#documentroot for info on that)

Many hosts don't let you change these things yourself, so your mileage may vary. Some let you change them, but only with the built in admin tools (cPanel, for example) instead of via a command line or editing the raw config files.

you can use _.range([optional] start, end). It creates a new Minified list containing an interval of numbers from start (inclusive) until the end (exclusive). Here I am using lodash.js ._range() method.

Example:

CODE

var dayOfMonth = _.range(1,32);  // It creates a new list from 1 to 31.

//HTML Now, you can use it in For loop

<div *ngFor="let day of dayOfMonth">{{day}}</div>

I've also had this issue.

I've found out that it is because Eclipse couldn't find all include headers.

Easy fix:

This simple and quick solution might fix your problem (for example, when the Eclipse project was moved to a different location on disk, then imported again in Eclipse), if not, jump to the next section (Detailed fix).

1. Go to project > properties > C/C++ Build > Tool Chain Editor
2. Change the Current toolchain to any other value, click Apply
3. Set the Current toolchain to the original value, click Apply
4. Compile your project

Detailed fix:

Before proceeding check if your toolchain is properly installed.

1. Switch to a new workspace.
2. Remove .cproject file and the ".settings" folder
3. Import your project as Makefile project (or just create a new if you prefer CDT Build system)
4. Go to project-> properties->C/C++ Build->Toolchain editor. Choose your toolchain.
5. Press project->Index->Rebuild
6. If the problem isn't resolved, change system language to English and try the above steps again.

Outdated answer:

This answer has been outdated. Proceed if nothing of the above helps

If the previous steps don't help we'll need to setup include directories manually (not recommended though)

1. Search all unresolved headers using "Right click on Project > Index > Search for unresolved includes".
2. Search their locations using "find /usr/include/ -name vector -print"
3. Put include folder paths to "Right click on Project > Properties > C++ General/Path and Symbols/C++"
4. Run "Right click on Project > Index > Rebuild"
5. Start from step 1 if there are any unresolved symbols left.

import config.logging_settings # pylint: disable=W0611

That was simple and is specific for that line.

You can and should use the more readable form:

import config.logging_settings # pylint: disable=unused-import

Using root, try something like this:

/etc/init.d/memcached restart

You can opt for this example below. Hope it will help.

/** @var ClassName $object */

$object->whateverMethod() // any method defined in the class can be accessed by $object

I know this is not a cast but it can be useful sometimes.

To understand why xmlns:android=“http://schemas.android.com/apk/res/android” must be the first in the layout xml file We shall understand the components using an example

Sample::

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/container" >    
</FrameLayout>

Uniform Resource Indicator(URI):

• In computing, a uniform resource identifier (URI) is a string of characters used to identify a name of a resource.
• Such identification enables interaction with representations of the resource over a network, typically the World Wide Web, using specific protocols.

Ex:http://schemas.android.com/apk/res/android:id is the URI here

XML Namespace:

• XML namespaces are used for providing uniquely named elements and attributes in an XML document. xmlns:android describes the android namespace.
• Its used like this because this is a design choice by google to handle the errors at compile time.
• Also suppose we write our own textview widget with different features compared to android textview, android namespace helps to distinguish between our custom textview widget and android textview widget

DECLARE @date DateTime
SET @date = GetDate()
SET @date = DateAdd(day, 1, @date)

SELECT @date

You can use CSS to do it for example

<style>
html{
    width:100%;
    height:100%;
}
body{
    width:100%;
    height:100%;
    background-color:#DDD;
}
</style>

you can set android theme of the checkbox to get the color you want in your styles.xml add :

<style name="checkBoxStyle" parent="Base.Theme.AppCompat">
    <item name="colorAccent">CHECKEDHIGHLIGHTCOLOR</item>
    <item name="android:textColorSecondary">UNCHECKEDCOLOR</item>
</style>

then in your layout file :

<CheckBox
     android:theme="@style/checkBoxStyle"
     android:id="@+id/chooseItemCheckBox"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"/>

unlike using android:buttonTint="@color/CHECK_COLOR" this method works under Api 23

I finally stumbled upon this link "A CORS POST request works from plain javascript, but why not with jQuery?" that notes that jQuery 1.5.1 adds the

 Access-Control-Request-Headers: x-requested-with

header to all CORS requests. jQuery 1.5.2 does not do this. Also, according to the same question, setting a server response header of

Access-Control-Allow-Headers: *

does not allow the response to continue. You need to ensure the response header specifically includes the required headers. ie:

Access-Control-Allow-Headers: x-requested-with 

smiley favicon to prevent error:

 //const fs = require('fs'); 
 //const favicon = fs.readFileSync(__dirname+'/public/favicon.ico'); // read file
 const favicon = new Buffer.from('AAABAAEAEBAQAAAAAAAoAQAAFgAAACgAAAAQAAAAIAAAAAEABAAAAAAAgAAAAAAAAAAAAAAAEAAAAAAAAAAAAAAA/4QAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAEREQAAAAAAEAAAEAAAAAEAAAABAAAAEAAAAAAQAAAQAAAAABAAAAAAAAAAAAAAAAAAAAAAAAAAEAABAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAD//wAA//8AAP//AAD8HwAA++8AAPf3AADv+wAA7/sAAP//AAD//wAA+98AAP//AAD//wAA//8AAP//AAD//wAA', 'base64'); 
 app.get("/favicon.ico", function(req, res) {
  res.statusCode = 200;
  res.setHeader('Content-Length', favicon.length);
  res.setHeader('Content-Type', 'image/x-icon');
  res.setHeader("Cache-Control", "public, max-age=2592000");                // expiers after a month
  res.setHeader("Expires", new Date(Date.now() + 2592000000).toUTCString());
  res.end(favicon);
 });

to change icon in code above

make an icon maybe here: http://www.favicon.cc/ or here :http://favicon-generator.org

convert it to base64 maybe here: http://base64converter.com/

then replace the icon base 64 value

general information how to create a personalized fav icon

icons are made using photoshop or inkscape, maybe inkscape then photoshop for vibrance and color correction (in image->adjustments menu).

for quick icon goto http://www.clker.com/ and pick some Vector Clip Arts, and download as svg. then bring it to inkscape (https://inkscape.org/) and change colors or delete parts, maybe add something from another vector clipart image, then to export select the parts to export and click file>export, pick size like 16x16 for favicon or 32x32. for further edit 128x128 or 256x256. ico package can have several icon sizes inside. it can have along with 16x16 pixel favicon a high quality icons for link for the website.

then maybe enhance the image in photoshop. like vibrance, bevel effect, round mask, anything.

then upload this image to one of the websites that generate favicons. there are also programs for windows for editing icons like https://sourceforge.net/projects/variicons/ .

to add the favicon to website. just put the favicon.ico as a file in the root folder of the domain. for example in node.js in public folder that contains the static files. it doesn't have to be anything special like code above just a simple file.

Change to another USB port works for me. I tried reset ADB, but problem still there.

: can also be for block comment (similar to /* */ in C language). For example, if you want to skip a block of code in your script, you can do this:

: << 'SKIP'

your code block here

SKIP

Alternatively, in python 3.6+, you can generate Unicode superscript and copy paste that in your code:

ax1.set_ylabel('Rate (min?¹)')

private static Long DateTimeNowTicks(){
    long TICKS_AT_EPOCH = 621355968000000000L;
    TimeZone timeZone = Calendar.getInstance().getTimeZone();
    int offs = timeZone.getRawOffset();
    if (timeZone.inDaylightTime(new Date()))
        offs += 60 * 60 * 1000;
    return (System.currentTimeMillis() + offs) * 10000 + TICKS_AT_EPOCH;
}

I ran into the same problem and reported it as a bug on the Facebook developer site. It seems pretty clear that og:image URIs using HTTP work just fine and URIs using HTTPS do not. They have now acknowledged that they are "looking into this."

Update: As of 2020, the bug is no longer visible in Facebook's ticket system. They never responded and I don't believe this behavior has changed. However, specifying HTTPS URI in og:image:secure does seem to be working fine.

There is no such limit on the string length. To be certain, I just tested to create a string containing 60 megabyte.

The problem is likely that you are sending the data in a GET request, so it's sent in the URL. Different browsers have different limits for the URL, where IE has the lowest limist of about 2 kB. To be safe, you should never send more data than about a kilobyte in a GET request.

To send that much data, you have to send it in a POST request instead. The browser has no hard limit on the size of a post, but the server has a limit on how large a request can be. IIS for example has a default limit of 4 MB, but it's possible to adjust the limit if you would ever need to send more data than that.

Also, you shouldn't use += to concatenate long strings. For each iteration there is more and more data to move, so it gets slower and slower the more items you have. Put the strings in an array and concatenate all the items at once:

var items = $.map(keys, function(item, i) {
  var value = $("#value" + (i+1)).val().replace(/"/g, "\\\"");
  return
    '{"Key":' + '"' + Encoder.htmlEncode($(this).html()) + '"' + ",'+
    '" + '"Value"' + ':' + '"' + Encoder.htmlEncode(value) + '"}';
});
var jsonObj =
  '{"code":"' + code + '",'+
  '"defaultfile":"' + defaultfile + '",'+
  '"filename":"' + currentFile + '",'+
  '"lstResDef":[' + items.join(',') + ']}';

The limitation of execl is that when executing a shell command or any other script that is not in the current working directory, then we have to pass the full path of the command or the script. Example:

execl("/bin/ls", "ls", "-la", NULL);

The workaround to passing the full path of the executable is to use the function execlp, that searches for the file (1st argument of execlp) in those directories pointed by PATH:

execlp("ls", "ls", "-la", NULL);

Suspended. The session is waiting for an event, such as I/O, to complete.

Having /A without additional parameters other than the filename didn't work for me, but the following code worked fine with /n

string sfile = @".\help\delta-pqca-400-100-300-fc4-user-manual.pdf";
Process myProcess = new Process();
myProcess.StartInfo.FileName = "AcroRd32.exe"; 
myProcess.StartInfo.Arguments = " /n " + "\"" + sfile + "\"";
myProcess.Start();

Another way to understand the relationship between these concepts is to interpret a ROLE as a container of Authorities.

Authorities are fine-grained permissions targeting a specific action coupled sometimes with specific data scope or context. For instance, Read, Write, Manage, can represent various levels of permissions to a given scope of information.

Also, authorities are enforced deep in the processing flow of a request while ROLE are filtered by request filter way before reaching the Controller. Best practices prescribe implementing the authorities enforcement past the Controller in the business layer.

On the other hand, ROLES are coarse grained representation of an set of permissions. A ROLE_READER would only have Read or View authority while a ROLE_EDITOR would have both Read and Write. Roles are mainly used for a first screening at the outskirt of the request processing such as http. ... .antMatcher(...).hasRole(ROLE_MANAGER)

The Authorities being enforced deep in the request's process flow allows a finer grained application of the permission. For instance, a user may have Read Write permission to first level a resource but only Read to a sub-resource. Having a ROLE_READER would restrain his right to edit the first level resource as he needs the Write permission to edit this resource but a @PreAuthorize interceptor could block his tentative to edit the sub-resource.

Node v0.6.x has a stable zlib module in core now - there are some examples on how to use it server-side in the docs too.

An example (taken from the docs):

// server example
// Running a gzip operation on every request is quite expensive.
// It would be much more efficient to cache the compressed buffer.
var zlib = require('zlib');
var http = require('http');
var fs = require('fs');
http.createServer(function(request, response) {
  var raw = fs.createReadStream('index.html');
  var acceptEncoding = request.headers['accept-encoding'];
  if (!acceptEncoding) {
    acceptEncoding = '';
  }

  // Note: this is not a conformant accept-encoding parser.
  // See http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.3
  if (acceptEncoding.match(/\bdeflate\b/)) {
    response.writeHead(200, { 'content-encoding': 'deflate' });
    raw.pipe(zlib.createDeflate()).pipe(response);
  } else if (acceptEncoding.match(/\bgzip\b/)) {
    response.writeHead(200, { 'content-encoding': 'gzip' });
    raw.pipe(zlib.createGzip()).pipe(response);
  } else {
    response.writeHead(200, {});
    raw.pipe(response);
  }
}).listen(1337);

The Zeus editor has support for C/C++ and it also has a form of intellisensing.

It does its intellisensing using the tags information produced by ctags:

alt text http://www.zeusedit.com/images/_lookmain.jpg

The data URI format is:

data:<headers>;<encoding>,<data>

So, you need only append your data to the "data:image/jpeg;," string:

var your_binary_data = document.body.innerText.replace(/(..)/gim,'%$1'); // parse text data to URI format

window.open('data:image/jpeg;,'+your_binary_data);

You can create a file that attempts to include a bogus system header. If you run gcc in verbose mode on such a source, it will list all the system include locations as it looks for the bogus header.

$ echo "#include <bogus.h>" > t.c; gcc -v t.c; rm t.c

[..]

#include "..." search starts here:
#include <...> search starts here:
 /usr/local/include
 /usr/lib/gcc/i686-apple-darwin9/4.0.1/include
 /usr/include
 /System/Library/Frameworks (framework directory)
 /Library/Frameworks (framework directory)
End of search list.

[..]

t.c:1:32: error: bogus.h: No such file or directory

Both the other answers accomplish what you want.

You can use the pivot functionality to arrange the data in a nice table

df.groupby(['Fruit','Name'],as_index = False).sum().pivot('Fruit','Name').fillna(0)



Name    Bob     Mike    Steve   Tom    Tony
Fruit                   
Apples  16.0    9.0     10.0    0.0     0.0
Grapes  35.0    0.0     0.0     87.0    15.0
Oranges 67.0    57.0    0.0     15.0    1.0

In Excel, the substring function is called MID function, and indexOf is called FIND for case-sensitive location and SEARCH function for non-case-sensitive location. For the first portion of your text parsing the LEFT function may also be useful.

See all the text functions here: Text Functions (reference).

Nothing above made it work for me. The thing for me is that I was testing a subscription and i forgot SkuType.SUBS, changing it to INAPP for the reserved google test product fixed it.

The fastest way I can think of

array_unshift($arr, null);
unset($arr[0]);
print_r($arr);

And if you just want to reindex the array(start at zero) and you have PHP +7.3 you can do it this way

array_unshift($arr);

I believe array_unshift is better than array_values as the former does not create a copy of the array.

Getting a valid TZ Database timezone name in PHP is a two-step process:

1. With JavaScript, get timezone offset in minutes through getTimezoneOffset. This offset will be positive if the local timezone is behind UTC and negative if it is ahead. So you must add an opposite sign to the offset.

   var timezone_offset_minutes = new Date().getTimezoneOffset();
   timezone_offset_minutes = timezone_offset_minutes == 0 ? 0 : -timezone_offset_minutes;
   

   Pass this offset to PHP.

2. In PHP convert this offset into a valid timezone name with timezone_name_from_abbr function.

   // Just an example.
   $timezone_offset_minutes = -360;  // $_GET['timezone_offset_minutes']
   
   // Convert minutes to seconds
   $timezone_name = timezone_name_from_abbr("", $timezone_offset_minutes*60, false);
   
   // America/Chicago
   echo $timezone_name;</code></pre>
   

I've written a blog post on it: How to Detect User Timezone in PHP. It also contains a demo.

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

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

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

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

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

This will delete the dataframe and will release the RAM/memory

del [[df_1,df_2]]
gc.collect()
df_1=pd.DataFrame()
df_2=pd.DataFrame()

the data-frame will be explicitly set to null

in the above statements

Firstly, the self reference of the dataframe is deleted meaning the dataframe is no longer available to python there after all the references of the dataframe is collected by garbage collector (gc.collect()) and then explicitly set all the references to empty dataframe.

more on the working of garbage collector is well explained in https://stackify.com/python-garbage-collection/

best and simple way is to put title inside a span and replace then.

'<div id="'+div_id+'" class="widget" style="height:60px;width:110px">\n\
        <div class="widget-head ui-widget-header" 
                style="cursor:move;height:20px;width:130px">'+
     '<span id="'+span_id+'" style="float:right; cursor:pointer" 
            class="dialog_link ui-icon ui-icon-newwin ui-icon-pencil"></span>' +
      '<span id="spTitle">'+
      dialog_title+ '</span>'
 '</div></div>

now you can simply use this:

$('#'+div_id+' .widget-head sp#spTitle').text("new dialog title");

I Hope this will help you.
