Here in this case, we are having 3 parameter's in the Method namely ModelandView.
According to this question, the first parameter is easily understood. It represents the View which will be displayed to the client.
The other two parameters are just like The Pointer and The Holder
Hence you can sum it up like this

ModelAndView(View, Pointer, Holder);

The Pointer just points the information in the The Holder

When the Controller binds the View with this information, then in the said process, you can use The Pointer in the JSP page to access the information stored in The Holder to display that respected information to the client.
Here is the visual depiction of the respected process.

return new ModelAndView("welcomePage", "WelcomeMessage", message);

Use std::find, something like:

if (std::find(std::begin(my_list), std::end(my_list), my_var) != std::end(my_list))
    // my_list has my_var

Cookie is just another HTTP header.

import urllib2
opener = urllib2.build_opener()
opener.addheaders.append(('Cookie', 'cookiename=cookievalue'))
f = opener.open("http://example.com/")

See urllib2 examples for other ways how to add HTTP headers to your request.

There are more ways how to handle cookies. Some modules like cookielib try to behave like web browser - remember what cookies did you get previously and automatically send them again in following requests.

ORA-01422: exact fetch returns more than requested number of rows

if you don't specify the exact record by using where condition, you will get the above exception

DECLARE
     ID NUMBER;
BEGIN
     select eid into id from employee where salary=26500;
     DBMS_OUTPUT.PUT_LINE(ID);
END;

As other have said, TRUNCATE TABLE is far quicker, but it does have some restrictions (taken from here):

You cannot use TRUNCATE TABLE on tables that:

- Are referenced by a FOREIGN KEY constraint. (You can truncate a table that has a foreign key that references itself.)
- Participate in an indexed view.
- Are published by using transactional replication or merge replication.

For tables with one or more of these characteristics, use the DELETE statement instead.

The biggest drawback is that if the table you are trying to empty has foreign keys pointing to it, then the truncate call will fail.

According to the Git Cheatsheet you have to create the branch first

git branch [branchName]

and then

git checkout [branchName]

If you want a localized number of days between two dates (startDate, endDate):

var currentLocaleData = moment.localeData("en");
var duration = moment.duration(endDate.diff(startDate));
var nbDays = Math.floor(duration.asDays()); // complete days
var nbDaysStr = currentLocaleData.relativeTime(returnVal.days, false, "dd", false);

nbDaysStr will contain something like '3 days';

See https://momentjs.com/docs/#/i18n/changing-locale/ for information on how to display the amount of hours or month, for example.

I was making my own version of a Checkbox to control a DataGridViewCheckBoxColumn when I saw this post wasn't actually answered. To set the checked state of a DataGridViewCheckBoxCell use:

foreach (DataGridViewRow row in dataGridView1.Rows)
{
    dataGridView1.Rows[row.Index].SetValues(true);
}

For anyone else trying to accomplish the same thing, here is what I came up with.

This makes the two controls behave like the checkbox column in Gmail. It keeps functionality for both mouse and keyboard.

using System;
using System.Windows.Forms;

namespace Check_UnCheck_All
{
    public partial class Check_UnCheck_All : Form
    {
        public Check_UnCheck_All()
        {
            InitializeComponent();
            dataGridView1.RowCount = 10;
            dataGridView1.AllowUserToAddRows = false;
            this.dataGridView1.CellContentClick += new System.Windows.Forms.DataGridViewCellEventHandler(this.dgvApps_CellContentClick);
            this.dataGridView1.CellMouseUp += new System.Windows.Forms.DataGridViewCellMouseEventHandler(this.myDataGrid_OnCellMouseUp);
            this.dataGridView1.CellValueChanged += new System.Windows.Forms.DataGridViewCellEventHandler(this.myDataGrid_OnCellValueChanged);
            this.checkBox1.Click += new System.EventHandler(this.checkBox1_Click);
        }

                if (Convert.ToBoolean(chk.Value) == false) chkInt--;

I was reading path from a properties file and didn't mention there was a space in the end. Make sure you don't have one.

This is a very old thread, but here's a very thorough answer and sample code.

\r is the string representation of Carriage Return from the ASCII character set. It's the same as octal 015 [chr(0o15)] or hexidecimal 0d [chr(0x0d)] or decimal 13 [chr(13)]. See man ascii for a boring read. It (\r) is a pretty portable representation and is easy enough for people to read. It very simply means to move the carriage on the typewriter all the way back to the start without advancing the paper. It's the CR part of CRLF which means Carriage Return and Line Feed.

print() is a function in Python 3. In Python 2 (any version that you'd be interested in using), print can be forced into a function by importing its definition from the __future__ module. The benefit of the print function is that you can specify what to print at the end, overriding the default behavior of \n to print a newline at the end of every print() call.

sys.stdout.flush tells Python to flush the output of standard output, which is where you send output with print() unless you specify otherwise. You can also get the same behavior by running with python -u or setting environment variable PYTHONUNBUFFERED=1, thereby skipping the import sys and sys.stdout.flush() calls. The amount you gain by doing that is almost exactly zero and isn't very easy to debug if you conveniently forget that you have to do that step before your application behaves properly.

And a sample. Note that this runs perfectly in Python 2 or 3.

from __future__ import print_function

import sys
import time

ANS = 42
FACTORS = {n for n in range(1, ANS + 1) if ANS % n == 0}

for i in range(1, ANS + 1):
    if i in FACTORS:
        print('\r{0:d}'.format(i), end='')
        sys.stdout.flush()
        time.sleep(ANS / 100.0)
else:
    print()

I found the answer: I need to add a new application to the service components in my computer and then add the right DLL's.

Thanks! If anyone has the same problem, I'll be happy to help.

Tried above steps, didn't work on Ubuntu 20. For Ubuntu 20, remove the cmdtest and yarn like suggested above. Install yarn with below commands:

curl -sL https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -

echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list

sudo apt update && sudo apt install yarn

You can't. Variables defined inside a method are local to that method.

If you want to share variables between methods, then you'll need to specify them as member variables of the class. Alternatively, you can pass them from one method to another as arguments (this isn't always applicable).

Looks like you're using instance methods instead of static ones.

If you don't want to create an object, you should declare all your methods static, so something like

private static void methodName(Argument args...)

If you want a variable to be accessible by all these methods, you should initialise it outside the methods and to limit its scope, declare it private.

private static int[][] array = new int[3][5];

Global variables are usually looked down upon (especially for situations like your one) because in a large-scale program they can wreak havoc, so making it private will prevent some problems at the least.

Also, I'll say the usual: You should try to keep your code a bit tidy. Use descriptive class, method and variable names and keep your code neat (with proper indentation, linebreaks etc.) and consistent.

Here's a final (shortened) example of what your code should be like:

public class Test3 {
    //Use this array in your methods
    private static int[][] scores = new int[3][5];

    /* Rather than just "Scores" name it so people know what
     * to expect
     */
    private static void createScores() {
        //Code...
    }
    //Other methods...

    /* Since you're now using static methods, you don't 
     * have to initialise an object and call its methods.
     */
    public static void main(String[] args){
        createScores();
        MD();   //Don't know what these do
        sumD(); //so I'll leave them.
    }
}

Ideally, since you're using an array, you would create the array in the main method and pass it as an argument across each method, but explaining how that works is probably a whole new question on its own so I'll leave it at that.

The code works as best I can tell. I would fire up Sysinternals process explorer and find out what is holding the file open. It might very well be Visual Studio.

'Millis since unix epoch' represents an instant, so you should use the Instant class:

private long toEpochMilli(LocalDateTime localDateTime)
{
  return localDateTime.atZone(ZoneId.systemDefault())
    .toInstant().toEpochMilli();
}

Generally you should watch out for deeply nested objects in React state. To avoid unexpected behavior, the state should be updated immutably. When you have deep objects, you end up deep cloning them for immutability, which can be quite expensive in React. Why?

Once you deep clone the state, React will recalculate and re-render everything that depends on the variables, even though they haven't changed!

So, before trying to solve your issue, think how you can flatten the state first. As soon as you do that, you will find beautiful tools that will help dealing with large states, such as useReducer().

In case you thought about it, but are still convinced you need to use a deeply nested state tree, you can still use useState() with libraries like immutable.js and Immutability-helper. They make it simple to update or clone deep objects without having to worry about mutability.

I used this expression for my case, it includes all the characters available in the text.

Solved it:

I had to use Mo'Bulletproofer method

I dump my output to a text file. I then open it in notepad ++ then click the show all characters button. Not very elegant but it works.

NOW() is used to insert the current date and time in the MySQL table. All fields with datatypes DATETIME, DATE, TIME & TIMESTAMP work good with this function.

YYYY-MM-DD HH:mm:SS

Demonstration:

Following code shows the usage of NOW()

INSERT INTO auto_ins
(MySQL_Function, DateTime, Date, Time, Year, TimeStamp)
VALUES
(“NOW()”, NOW(), NOW(), NOW(), NOW(), NOW());

A simple way to do it is by using:

new Date().getTimezoneOffset();

With reference to man ssh-keygen, the length of a DSA key is restricted to exactly 1024 bit to remain compliant with NIST's FIPS 186-2. Nonetheless, longer DSA keys are theoretically possible; FIPS 186-3 explicitly allows them. Furthermore, security is no longer guaranteed with 1024 bit long RSA or DSA keys.

In conclusion, a 2048 bit RSA key is currently the best choice.

MORE PRECAUTIONS TO TAKE

Establishing a secure SSH connection entails more than selecting safe encryption key pair technology. In view of Edward Snowden's NSA revelations, one has to be even more vigilant than what previously was deemed sufficient.

To name just one example, using a safe key exchange algorithm is equally important. Here is a nice overview of current best SSH hardening practices.

This problem is probably from your /etc/apt/sources.list as others mentioned but there is chance that the problem is with your hard disk. I solved the same issue by cleaning up some space.

When you don't have enough space on your hard disk, updating your machine won't occur until you delete some files.

$("a[href*=ABC]").addClass('selected');

execute this

EXEC sp_MSforeachtable 'PRINT ''ALTER TABLE ? NOCHECK CONSTRAINT ALL'''
EXEC sp_MSforeachtable 'print ''DELETE FROM ?'''
EXEC sp_MSforeachtable 'print ''ALTER TABLE ? WITH CHECK CHECK CONSTRAINT all'''

After copy the printed result and paste it on Query field and Execute it. It will truncate all tables.

Here is a small example how to add a matplotlib grid in Gtk3 with Python 2 (not working in Python 3):

#!/usr/bin/env python
#-*- coding: utf-8 -*-

import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk
from matplotlib.figure import Figure
from matplotlib.backends.backend_gtk3agg import FigureCanvasGTK3Agg as FigureCanvas

win = Gtk.Window()
win.connect("delete-event", Gtk.main_quit)
win.set_title("Embedding in GTK3")

f = Figure(figsize=(1, 1), dpi=100)
ax = f.add_subplot(111)
ax.grid()

canvas = FigureCanvas(f)
canvas.set_size_request(400, 400)
win.add(canvas)

win.show_all()
Gtk.main()

sure you can do that without using any addition, just pure javascript, by using this method of dns browser.dns.resolve("example.com"); but it is compatible just with FIREFOX 60 you can see more information on MDN https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/dns/resolve

The problem is you either haven't closed your if or you need an elseif:

create procedure checando(
    in nombrecillo varchar(30),
    in contrilla varchar(30), 
    out resultado int)
begin 

    if exists (select * from compas where nombre = nombrecillo and contrasenia = contrilla) then
        set resultado = 0;
    elseif exists (select * from compas where nombre = nombrecillo) then
        set resultado = -1;
    else 
        set resultado = -2;
    end if;
end;

One way to do it will be to move all the php code above the HTML, copy the result to a variable and then add the result in the <input> tag.
Try this -

<?php
//Adding the php to the top.
if(isset($_POST['submit']))
{
    $value1=$_POST['value1'];
    $value2=$_POST['value2'];
    $sign=$_POST['sign'];
    ...
        //Adding to $result variable
    if($sign=='-') {
      $result = $value1-$value2;
    }
    //Rest of your code...
}
?>
<html>
<!--Rest of your tags...-->
Result:<br><input type"text" name="result" value = "<?php echo (isset($result))?$result:'';?>">

This may be too basic (and perhaps assumable), but -

Fedora users can use:

sudo dnf install python-scipy

and then (For python3.x):

pip3 install scipy

or (For python2.7):

pip2 install scipy

There are a few packages for prettifying HTML. You can find them by searching the Atom package archive:

1. Navigate to the Atom site
2. Click the Packages link
3. Enter "prettify" in the search box

Or just go to this link: https://atom.io/packages/search?q=prettify

Once you've selected a package that does what you want you can install it by using the command: apm install [package name] from the command line or install it using the interface in Preferences.

When the package is installed, follow its instructions for how to activate its capabilities.

You cannot directly save a Python file as an exe and expect it to work -- the computer cannot automatically understand whatever code you happened to type in a text file. Instead, you need to use another program to transform your Python code into an exe.

I recommend using a program like Pyinstaller. It essentially takes the Python interpreter and bundles it with your script to turn it into a standalone exe that can be run on arbitrary computers that don't have Python installed (typically Windows computers, since Linux tends to come pre-installed with Python).

To install it, you can either download it from the linked website or use the command:

pip install pyinstaller

...from the command line. Then, for the most part, you simply navigate to the folder containing your source code via the command line and run:

pyinstaller myscript.py

You can find more information about how to use Pyinstaller and customize the build process via the documentation.

You don't necessarily have to use Pyinstaller, though. Here's a comparison of different programs that can be used to turn your Python code into an executable.

I'd suggest avoiding in-line JavaScript:

var aElems = document.getElementsByTagName('a');

for (var i = 0, len = aElems.length; i < len; i++) {
    aElems[i].onclick = function() {
        var check = confirm("Are you sure you want to leave?");
        if (check == true) {
            return true;
        }
        else {
            return false;
        }
    };
}?

JS Fiddle demo.

The above updated to reduce space, though maintaining clarity/function:

var aElems = document.getElementsByTagName('a');

for (var i = 0, len = aElems.length; i < len; i++) {
    aElems[i].onclick = function() {
        return confirm("Are you sure you want to leave?");
    };
}

JS Fiddle demo.

A somewhat belated update, to use addEventListener() (as suggested, by bažmegakapa, in the comments below):

function reallySure (event) {
    var message = 'Are you sure about that?';
    action = confirm(message) ? true : event.preventDefault();
}
var aElems = document.getElementsByTagName('a');

for (var i = 0, len = aElems.length; i < len; i++) {
    aElems[i].addEventListener('click', reallySure);
}

JS Fiddle demo.

The above binds a function to the event of each individual link; which is potentially quite wasteful, when you could bind the event-handling (using delegation) to an ancestor element, such as the following:

function reallySure (event) {
    var message = 'Are you sure about that?';
    action = confirm(message) ? true : event.preventDefault();
}

function actionToFunction (event) {
    switch (event.target.tagName.toLowerCase()) {
        case 'a' :
            reallySure(event);
            break;
        default:
            break;
    }
}

document.body.addEventListener('click', actionToFunction);

JS Fiddle demo.

Because the event-handling is attached to the body element, which normally contains a host of other, clickable, elements I've used an interim function (actionToFunction) to determine what to do with that click. If the clicked element is a link, and therefore has a tagName of a, the click-handling is passed to the reallySure() function.

• addEventListener().
• Conditional ('ternary') operator.
• confirm().

• onclick.

This error really just has to do with the file Path,thats all you have to check,for me my parent folder was "Layouts" but my actual file was layout.html,my path had layouts on both,once i corrected that error was gone.

Imagine being an OS working with a string that some other thread was modifying behind your back. How could you validate anything without making a copy?

For Java folks, Apache has a utility class (StringEscapeUtils) that has a helper method escapeXml which can be used for escaping characters in a string using XML entities.

cout<<"enter a decimal number\n";
cin>>str;
for(i=0;i<str.size();i++)
{
    if(str[i]=='.')
    break;
}

for(j=i+1;j<str.size();j++)
{
    cout<<str[j];
}

If you want to take advantage of the hash diff Rspec provides, it is better to parse the body and compare against a hash. Simplest way I've found:

it 'asserts json body' do
  expected_body = {
    my: 'json',
    hash: 'ok'
  }.stringify_keys

  expect(JSON.parse(response.body)).to eql(expected_body)
end

This is not shorter, but it deals with detached branches as well:

git branch | awk -v FS=' ' '/\*/{print $NF}' | sed 's|[()]||g'

Just clean your server (in my case I was using Tomcat):

mvn clean
mvn install

As Leigh Caldwell has stated, the query optimizer can produce different query plans based on what functionally looks like the same SQL statement. For further reading on this, have a look at the following two blog postings:-

Another posting from the "Structured Data" blog

I hope you find this interesting.

Try the following (note that there should not be a space between the VAR, =, and GREG).

SET VAR=GREG
ECHO %VAR%
PAUSE

Exception is a checked exception class. Therefore, any code that calls a method that declares that it throws Exception must handle or declare it.

Karate is exactly what you are looking for. Here is an example:

* def myJson = { foo: 'world', hey: 'ho', zee: [5], cat: { name: 'Billie' } }
* match myJson = { cat: { name: 'Billie' }, hey: 'ho', foo: 'world', zee: [5] }

Try the --force option. svn help checkout gives the details.

DELETE FROM on_search 
WHERE search_date < UNIX_TIMESTAMP(DATE_SUB(NOW(), INTERVAL 180 DAY))

With new version of Lombok you can compile that cute class:

@Value(staticConstructor = "of") public class Pair <E> {
  E first, second;
}

and use it like: Pair<Value> pairOfValues = Pair.of(value1, value2);

I don't think there's a standard as to the location of the sitemap. That's the reason why you should specify an arbitrary URL to your sitemap when you're adding one using Google's Webmaster Tools.

Here is yet another way to create a decelerating/accelerating interval timer. The interval gets multiplied by a factor until a total time is exceeded.

function setChangingInterval(callback, startInterval, factor, totalTime) {
    let remainingTime = totalTime;
    let interval = startInterval;

    const internalTimer = () => {
        remainingTime -= interval ;
        interval *= factor;
        if (remainingTime >= 0) {
            setTimeout(internalTimer, interval);
            callback();
        }
    };
    internalTimer();
}

You want to join on condition 1 AND condition 2, so simply use the AND keyword as below

ON a.userid = b.sourceid AND a.listid = b.destinationid;

A lot depends on what kind of project it is. WTP's JSP support either expects the JSP files to be under the same folder that's the parent of the WEB-INF folder (src/web, which it will then treat as "/" to find TLDs), or to have project metadata set up to help it know where that root is (done for you in a Dynamic Web Project through Deployment Assembly). How are you referring to the TLD file, and where is the JSP file located?

And maybe I missed the original post to the Eclipse forums; the one I saw was posted a full day after this one.

Obfuscating things can only inconvenience your legitimate, law-abiding customers, while the people who would would rip you off are not your target paying customers anyway. (edited out other thoughts about obfuscation)

Another suggestion for protecting your software: create a business model in which the code is an incomplete part of the value of your offering. For example, sell product licenses along with access to some data you manage on your site, or license the product on a subscription model or with customer support.

Designing a EULA is a legal matter, not a coding matter. You can start by reading some EULA text for products and websites you use. You might find some interesting details!

Creating a proprietary license is is highly flexible, and probably a subject beyond the intended scope of StackOverflow, since it's not strictly about coding.

Some parts of a EULA that come to mind:

• Limiting your liability if the product has bugs or causes damage.
• Spelling out how the customer can use their licensed software, for how long, on how many machines, with or without redistribution rights, etc.
• Giving you rights to audit their site, so you can enforce the licenses.
• What happens if they violate the EULA, e.g. they lose their privilege to use your software.

You should consult a legal professional to prepare a commercial EULA.

Your time string is similar to the time format in rfc 2822 (date format in email, http headers). You could parse it using only stdlib:

>>> from email.utils import parsedate_tz
>>> parsedate_tz('Tue Jun 22 07:46:22 EST 2010')
(2010, 6, 22, 7, 46, 22, 0, 1, -1, -18000)

See solutions that yield timezone-aware datetime objects for various Python versions: parsing date with timezone from an email.

In this format, EST is semantically equivalent to -0500. Though, in general, a timezone abbreviation is not enough, to identify a timezone uniquely.

use MD5,

$query="INSERT INTO ptb_users (id,
user_id,
first_name,
last_name,
email )
VALUES('NULL',
'NULL',
'".$firstname."',
'".$lastname."',
'".$email."',
MD5('".$password."')
)";

but MD5 is insecure. Use SHA2.

Type the kill -l command on your shell

you will found that at 9th number [ 9) SIGKILL ], so one can use either kill -9 or kill -SIGKILL

SIGKILL is sure kill signal, It can not be dis-positioned, ignore or handle. It always work with its default behaviour, which is to kill the process.

This question is old. But I would like to mention an other approach. Using Enums for declaring constant values. Based on the answer of Nandkumar Tekale, the Enum can be used as below:

Enum:

public enum Planck {
    REDUCED();
    public static final double PLANCK_CONSTANT = 6.62606896e-34;
    public static final double PI = 3.14159;
    public final double REDUCED_PLANCK_CONSTANT;

    Planck() {
        this.REDUCED_PLANCK_CONSTANT = PLANCK_CONSTANT / (2 * PI);
    }

    public double getValue() {
        return REDUCED_PLANCK_CONSTANT;
    }
}

Client class:

public class PlanckClient {

    public static void main(String[] args) {
        System.out.println(getReducedPlanckConstant());
        // or using Enum itself as below:
        System.out.println(Planck.REDUCED.getValue());
    }

    public static double getReducedPlanckConstant() {
        return Planck.PLANCK_CONSTANT / (2 * Planck.PI);
    }

}

Reference : The usage of Enums for declaring constant fields is suggested by Joshua Bloch in his Effective Java book.

In general you just have to define a slightly transparent color when creating the shape.

You can achieve that by setting the colors alpha channel.

#FF000000 will get you a solid black whereas #00000000 will get you a 100% transparent black (well it isn't black anymore obviously).

The color scheme is like this #AARRGGBB there A stands for alpha channel, R stands for red, G for green and B for blue.

The same thing applies if you set the color in Java. There it will only look like 0xFF000000.

UPDATE

In your case you'd have to add a solid node. Like below.

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/shape_my">
    <stroke android:width="4dp" android:color="#636161" />
    <padding android:left="20dp"
        android:top="20dp"
        android:right="20dp"
        android:bottom="20dp" />
    <corners android:radius="24dp" />
    <solid android:color="#88000000" />
</shape>

The color here is a half transparent black.

Java class final and method final -> sealed. Java member variable final -> readonly for runtime constant, const for compile time constant.

No equivalent for Local Variable final and method argument final

Cyclic imports terminate, but you need to be careful not to use the cyclically-imported modules during module initialization.

Consider the following files:

a.py:

print "a in"
import sys
print "b imported: %s" % ("b" in sys.modules, )
import b
print "a out"

b.py:

print "b in"
import a
print "b out"
x = 3

If you execute a.py, you'll get the following:

$ python a.py
a in
b imported: False
b in
a in
b imported: True
a out
b out
a out

On the second import of b.py (in the second a in), the Python interpreter does not import b again, because it already exists in the module dict.

If you try to access b.x from a during module initialization, you will get an AttributeError.

Append the following line to a.py:

print b.x

Then, the output is:

$ python a.py
a in                    
b imported: False
b in
a in
b imported: True
a out
Traceback (most recent call last):
  File "a.py", line 4, in <module>
    import b
  File "/home/shlomme/tmp/x/b.py", line 2, in <module>
    import a
 File "/home/shlomme/tmp/x/a.py", line 7, in <module>
    print b.x
AttributeError: 'module' object has no attribute 'x'

This is because modules are executed on import and at the time b.x is accessed, the line x = 3 has not be executed yet, which will only happen after b out.

You need to consider that GROUP BY happens after the WHERE clause conditions have been evaluated. And the WHERE clause always considers only one row, meaning that in your query, the meta_key conditions will always prevent any records from being selected, since one column cannot have multiple values for one row.

And what about the redundant meta_value checks? If a value is allowed to be both smaller and greater than a given value, then its actual value doesn't matter at all - the check can be omitted.

According to one of your comments you want to check for places less than a certain distance from a given location. To get correct distances, you'd actually have to use some kind of proper distance function (see e.g. this question for details). But this SQL should give you an idea how to start:

SELECT items.* FROM items i, meta_data m1, meta_data m2
    WHERE i.item_id = m1.item_id and i.item_id = m2.item_id
    AND m1.meta_key = 'lat' AND m1.meta_value >= 55 AND m1.meta_value <= 65
    AND m2.meta_key = 'lng' AND m2.meta_value >= 20 AND m2.meta_value <= 30

A straightforward approach would be the following:

string[] tokens = str.Split(' ');
string retVal = tokens[0] + " " + tokens[1];

For Googlers:

• DO NOT mix statefulness with state transfer mechanisms

STATEFULNESS

• Stateful = save authorization info on server side, this is the traditional way
• Stateless = save authorization info on client side, along with a signature to ensure integrity

MECHANISMS

• Cookie = a special header with special treatment (access, storage, expiration, security, auto-transfer) by browsers
• Custom Headers = e.g. Authorization, are just headers without any special treatment, client has to manage all aspects of the transfer
• Other. Other transfer mechanisms may be utilized, e.g. query string was a choice to transfer auth ID for a while but was abandoned for its insecurity

STATEFULNESS COMPARISON

• "Stateful authorization" means the server stores and maintains user authorization info on server, making authorizations part of the application state
• This means client only need to keep an "auth ID" and the server can read auth detail from its database
• This implies that server keeps a pool of active auths (users that are logged in) and will query this info for every request
• "Stateless authorization" means the server does not store and maintain user auth info, it simply does not know which users are signed in, and rely on the client to produce auth info
• Client will store complete auth info like who you are (user ID), and possibly permissions, expiration time, etc., this is more than just auth ID, so it is given a new name token
• Obviously client cannot be trusted, so auth data is stored along with a signature generated from hash(data + secret key), where secret key is only known to server, so the integrity of token data can be verified
• Note that token mechanism merely ensures integrity, but not confidentiality, client has to implement that
• This also means for every request client has to submit a complete token, which incurs extra bandwidth

MECHANISM COMPARISON

• "Cookie" is just a header, but with some preloaded operations on browsers
• Cookie can be set by server and auto-saved by client, and will auto-send for same domain
• Cookie can be marked as httpOnly thus prevent client JavaScript access
• Preloaded operations may not be available on platforms other than browsers (e.g. mobile), which may lead to extra efforts
• "Custom headers" are just custom headers without preloaded operations
• Client is responsible to receive, store, secure, submit and update the custom header section for each requests, this may help prevent some simple malicious URL embedding

SUM-UP

• There is no magic, auth state has to be stored somewhere, either at server or client
• You may implement stateful/stateless with either cookie or other custom headers
• When people talk about those things their default mindset is mostly: stateless = token + custom header, stateful = auth ID + cookie; these are NOT the only possible options
• They have pros and cons, but even for encrypted tokens you should not store sensitive info

It seems that your Java code is using IPv6 instead of IPv4. Please try to use 127.0.0.1 instead of localhost. Ex.: Your connection string should be

jdbc:mysql://127.0.0.1:3306/expeditor?zeroDateTimeBehavior=convertToNull&user=root&password=onelife

P.S.: Please update the URL connection string.

I resolved this problem by setting the java version in Project Facet property of the project properties, Right click the project root folder -> Properties, search for Project Facets, and select compatible java version.

For reference -

Should it be LIBRARY_PATH instead of LD_LIBRARY_PATH. gcc checks for LIBRARY_PATH which can be seen with -v option

The best way to answer your question would be to make you familiar with the "String constant pool". In java string objects are immutable (i.e their values cannot be changed once they are initialized), so when editing a string object you end up creating a new edited string object wherease the old object just floats around in a special memory ares called the "string constant pool". creating a new string object by

String s = "Hello";

will only create a string object in the pool and the reference s will refer to it, but by using

String s = new String("Hello");

you create two string objects: one in the pool and the other in the heap. the reference will refer to the object in the heap.

I think I got this from not explicitly deleting some tables from the edmx before renaming and re-adding them. Instead, I just renamed the tables and then did an Update Model from Database, thinking it would see them gone, and delete them from model. I then did another Update Model from Database and added the renamed tables.

The site was working with the new tables, but I had the error. Eventually, I noticed the original tables were still in the model. I deleted them from the model (click them in edmx screen, delete key), and then the error went away.

I know this is old, but I ran into an issue where I was running a function after checking if there was a session. It would throw an error everytime I tried loading the page after logging out, still worked just logged an error page. Make sure you use exit(); if you are running into the same problem.

     function sessionexists(){
        if(!empty($_SESSION)){
     return true;
         }else{
     return false;
         }
      }


        if (!sessionexists()){
           redirect("https://www.yoursite.com/");
           exit();
           }else{call_user_func('check_the_page');
         } 

Remove the quotes here:

is:

ORDER BY = 'post_datetime DESC' AND LIMIT = '3'

Should be:

ORDER BY post_datetime DESC LIMIT 3

For anyone like me finding this question the following might be useful.

I had a similar problem and initially tried using location.go and location.replaceState as suggested in other answers here. However I ran into problems when I had to navigate to another page on the app because the navigation was relative to the current route and the current route wasn't being updated by location.go or location.replaceState (the router doesn't know anything about what these do to the URL)

In essence I needed a solution that DIDN'T reload the page/component when the route parameter changed but DID update the route state internally.

I ended up using query parameters. You can find more about it here: https://angular-2-training-book.rangle.io/handout/routing/query_params.html

So if you need to do something like save an order and get an order ID you can update your page URL like shown below. Updating a centre location and related data on a map would be similar

// let's say we're saving an order. Initally the URL is just blah/orders
save(orderId) {
    // [Here we would call back-end to save the order in the database]

    this.router.navigate(['orders'], { queryParams: { id: orderId } });
    // now the URL is blah/orders?id:1234. We don't reload the orders
    // page or component so get desired behaviour of not seeing any 
    // flickers or resetting the page.
}

and you keep track of it within the ngOnInit method like:

ngOnInit() {
    this.orderId = this.route
        .queryParamMap
        .map(params => params.get('id') || null);
    // orderID is up-to-date with what is saved in database now, or if
    // nothing is saved and hence no id query paramter the orderId variable
    // is simply null.
    // [You can load the order here from its ID if this suits your design]
}

If you need to go direct to the order page with a new (unsaved) order you can do:

this.router.navigate(['orders']);

Or if you need to go direct to the order page for an existing (saved) order you can do:

this.router.navigate(['orders'], { queryParams: { id: '1234' } });

You can change the collation of your text field to UTF8_general_ci and the problem will be solved.

Notice, this cannot be done in Django.

I agree with the accepted answer above but it is only good for known string values. For dynamic string values here is my suggestion.

// A list may come from an API JSON like
{
   "names": [
      "Person 1",
      "Person 2",
      "Person 3",
         ...
      "Person N"
   ]
}
var listOfNames = mutableListOf<String>() 

val stringOfNames = listOfNames.joinToString(", ") 
// ", " <- a separator for the strings, could be any string that you want

// Posible result
// Person 1, Person 2, Person 3, ..., Person N

This is useful for concatenating list of strings with separator.

pip install --user package-name

Seems to work, but the package is install the the path of user. such as :

"c:\users\***\appdata\local\temp\pip-req-tracker-_akmzo\42a6c7d627641b148564ff35597ec30fd5543aa1cf6e41118b98d7a3"

I want to install the package in python folder such c:\Python27. I install the module into the expected folder by:

pip install package-name --no-cache-dir

You can use this for getting current and log times:

#!/bin/bash

log="log_file_name"
while read line
do
  current_hours=`date | awk 'BEGIN{FS="[ :]+"}; {print $4}'`
  current_minutes=`date | awk 'BEGIN{FS="[ :]+"}; {print $5}'`
  current_seconds=`date | awk 'BEGIN{FS="[ :]+"}; {print $6}'`

  log_file_hours=`echo $line | awk 'BEGIN{FS="[ [/:]+"}; {print  $7}'`
  log_file_minutes=`echo $line | awk 'BEGIN{FS="[ [/:]+"}; {print  $8}'`
  log_file_seconds=`echo $line | awk 'BEGIN{FS="[ [/:]+"}; {print  $9}'`    
done < $log

And compare log_file_* and current_* variables.

You need to use the square brackets notation to have values sent as an array:

<form method='post' id='userform' action='thisform.php'>
<tr>
    <td>Trouble Type</td>
    <td>
    <input type='checkbox' name='checkboxvar[]' value='Option One'>1<br>
    <input type='checkbox' name='checkboxvar[]' value='Option Two'>2<br>
    <input type='checkbox' name='checkboxvar[]' value='Option Three'>3
    </td>
</tr>
</table>
<input type='submit' class='buttons'>
</form>

Please note though, that only the values of only checked checkboxes will be sent.

In general,

variable=$(command)

or

variable=`command`

The latter one is the old syntax, prefer $(command).

Note: variable = .... means execute the command variable with the first argument =, the second ....

For Android Studio 1.4, I had to do the following ...

In the project explorer window, open the "Gradle Scripts" folder.

Edit the gradle.properties file.

Append the following to the bottom, replacing the below values with your own where appropriate ...

systemProp.http.proxyHost=?.?.?.?
systemProp.http.proxyPort=8080
# Next line in form DOMAIN/USERNAME for NTLM or just USERNAME for non-NTLM
systemProp.http.proxyUser=DOMAIN/USERNAME
systemProp.http.proxyPassword=PASSWORD
systemProp.http.nonProxyHosts=localhost
# Next line is required for NTLM auth only
systemProp.http.auth.ntlm.domain=DOMAIN

systemProp.https.proxyHost=?.?.?.?
systemProp.https.proxyPort=8080
# Next line in form DOMAIN/USERNAME for NTLM or just USERNAME for non-NTLM
systemProp.https.proxyUser=DOMAIN/USERNAME
systemProp.https.proxyPassword=PASSWORD
systemProp.https.nonProxyHosts=localhost
# Next line is required for NTLM auth only
systemProp.https.auth.ntlm.domain=DOMAIN

Details of what gradle properties you can set are here... https://docs.gradle.org/current/userguide/userguide_single.html#sec%3aaccessing_the_web_via_a_proxy

I doubt there is one... It depends on browser, on printer (physical max dpi) and its driver, on paper size as you point out (and I might want to print on B5 paper too...), on settings (landscape or portrait?), plus you often can change the scale (percentage), etc.
Let the users tweak their settings...

This query will get you all the tables in the database

USE [DatabaseName];

SELECT * FROM information_schema.tables;

You can use LINQ Union method:

dir.GetFiles("*.txt").Union(dir.GetFiles("*.jpg")).ToArray();

Your DOS command 2> nul

Read page Using command redirection operators. Besides the "2>" construct mentioned by Tanuki Software, it lists some other useful combinations.

Message queues are asynchronous and can retry a number of times if delivery fails. Use a message queue if the requester doesn't need to wait for a response.

The phrase "web services" make me think of synchronous calls to a distributed component over HTTP. Use web services if the requester needs a response back.

There are at least two ways for achieving this in base graph (my examples are for the x-axis, but work the same for the y-axis):

1. Use par(xaxp = c(x1, x2, n)) or plot(..., xaxp = c(x1, x2, n)) to define the position (x1 & x2) of the extreme tick marks and the number of intervals between the tick marks (n). Accordingly, n+1 is the number of tick marks drawn. (This works only if you use no logarithmic scale, for the behavior with logarithmic scales see ?par.)

2. You can suppress the drawing of the axis altogether and add the tick marks later with axis().
   To suppress the drawing of the axis use plot(... , xaxt = "n").
   Then call axis() with side, at, and labels: axis(side = 1, at = v1, labels = v2). With side referring to the side of the axis (1 = x-axis, 2 = y-axis), v1 being a vector containing the position of the ticks (e.g., c(1, 3, 5) if your axis ranges from 0 to 6 and you want three marks), and v2 a vector containing the labels for the specified tick marks (must be of same length as v1, e.g., c("group a", "group b", "group c")). See ?axis and my updated answer to a post on stats.stackexchange for an example of this method.

Use these two step in console :

git commit --amend -m "new commit message"

and then

git push -f

Done :)

This is not how you do things in Java. There are no dynamic variables in Java. Java variables have to be declared in the source code¹.

Depending on what you are trying to achieve, you should use an array, a List or a Map; e.g.

int n[] = new int[3];
for (int i = 0; i < 3; i++) {
    n[i] = 5;
}

List<Integer> n = new ArrayList<Integer>();
for (int i = 1; i < 4; i++) {
    n.add(5);
}

Map<String, Integer> n = new HashMap<String, Integer>();
for (int i = 1; i < 4; i++) {
    n.put("n" + i, 5);
}

It is possible to use reflection to dynamically refer to variables that have been declared in the source code. However, this only works for variables that are class members (i.e. static and instance fields). It doesn't work for local variables. See @fyr's "quick and dirty" example.

However doing this kind of thing unnecessarily in Java is a bad idea. It is inefficient, the code is more complicated, and since you are relying on runtime checking it is more fragile. And this is not "variables with dynamic names". It is better described as dynamic access to variables with static names.

^{1 - That statement is slightly inaccurate. If you use BCEL or ASM, you can "declare" the variables in the bytecode file. But don't do it! That way lies madness!}

When you want to open an activity within your app then you can call the startActivity() method with an Intent as parameter. That intent would be the activity that you want to open. First you have to create an object of that intent with first parameter to be the context and second parameter to be the targeted activity class.

Intent intent = new Intent(this, Activity_a.class);
startActivity(intent);

Hope this will help.

Overview of OAuth: Is the User Who He/She Says He/She is?:

I'm not sure if you used OAuth to login to Stack Overflow, like the "Login with Google" option, but when you use this feature, Stack Overflow is simply asking Google if it knows who you are:

"Yo Google, this Vinesh fella claims that [email protected] is him, is that true?"

If you're logged in already, Google will say YES. If not, Google will say:

"Hang on a sec Stack Overflow, I'll authenticate this fella and if he can enter the right password for his Google account, then it's him".

When you enter your Google password, Google then tells Stack Overflow you are who you say you are, and Stack Overflow logs you in.

When you logout of your app, you're logging out of your app:

Here's where developers new to OAuth sometimes get a little confused... Google and Stack Overflow, Assembla, Vinesh's-very-cool-slick-webapp, are all different entities, and Google knows nothing about your account on Vinesh's cool webapp, and vice versa, aside from what's exposed via the API you're using to access profile information.

When your user logs out, he or she isn't logging out of Google, he/she is logging out of your app, or Stack Overflow, or Assembla, or whatever web application used Google OAuth to authenticate the user.

In fact, I can log out of all of my Google accounts and still be logged into Stack Overflow. Once your app knows who the user is, that person can log out of Google. Google is no longer needed.

With that said, what you're asking to do is log the user out of a service that really doesn't belong to you. Think about it like this: As a user, how annoyed do you think I would be if I logged into 5 different services with my Google account, then the first time I logged out of one of them, I have to login to my Gmail account again because that app developer decided that, when I log out of his application, I should also be logged out of Google? That's going to get old really fast. In short, you really don't want to do this...

Yeh yeh, whatever, I still want to log the user out Of Google, just tell me how do I do this?

With that said, if you still do want to log a user out of Google, and realize that you may very well be disrupting their workflow, you could dynamically build the logout url from one of their Google services logout button, and then invoke that using an img element or a script tag:

<script type="text/javascript" 
    src="https://mail.google.com/mail/u/0/?logout&hl=en" />

OR

<img src="https://mail.google.com/mail/u/0/?logout&hl=en" />

OR

window.location = "https://mail.google.com/mail/u/0/?logout&hl=en";

If you redirect your user to the logout page, or invoke it from an element that isn't cross-domain restricted, the user will be logged out of Google.

Note that this does not necessarily mean the user will be logged out of your application, only Google. :)

Summary:

What's important for you to keep in mind is that, when you logout of your app, you don't need to make the user re-enter a password. That's the whole point! It authenticates against Google so the user doesn't have to enter his or her password over and over and over again in each web application he or she uses. It takes some getting used to, but know that, as long as the user is logged into Google, your app doesn't need to worry about whether or not the user is who he/she says he/she is.

I have the same implementation in a project as you do, using the Google Profile information with OAuth. I tried the very same thing you're looking to try, and it really started making people angry when they had to login to Google over and over again, so we stopped logging them out of Google. :)

This solution does not require manual tweaking of axes locations or colorbar size, works with multi-row and single-row layouts, and works with tight_layout(). It is adapted from a gallery example, using ImageGrid from matplotlib's AxesGrid Toolbox.

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import ImageGrid

# Set up figure and image grid
fig = plt.figure(figsize=(9.75, 3))

grid = ImageGrid(fig, 111,          # as in plt.subplot(111)
                 nrows_ncols=(1,3),
                 axes_pad=0.15,
                 share_all=True,
                 cbar_location="right",
                 cbar_mode="single",
                 cbar_size="7%",
                 cbar_pad=0.15,
                 )

# Add data to image grid
for ax in grid:
    im = ax.imshow(np.random.random((10,10)), vmin=0, vmax=1)

# Colorbar
ax.cax.colorbar(im)
ax.cax.toggle_label(True)

#plt.tight_layout()    # Works, but may still require rect paramater to keep colorbar labels visible
plt.show()

All you need to do for that is a simple loop.
This doesn't handle testing for lower case, upper-case mismatch. If this isn't exactly what you are looking for, comment, and I can revise.

If you are planning to learn VBA. This is a great start.

TESTED:

Sub MatchAndColor()

Dim lastRow As Long
Dim sheetName As String

    sheetName = "Sheet1"            'Insert your sheet name here
    lastRow = Sheets(sheetName).Range("A" & Rows.Count).End(xlUp).Row

    For lRow = 2 To lastRow         'Loop through all rows

        If Sheets(sheetName).Cells(lRow, "A") = Sheets(sheetName).Cells(lRow, "B") Then
            Sheets(sheetName).Cells(lRow, "A").Interior.ColorIndex = 3  'Set Color to RED
        End If

    Next lRow

End Sub

If I recall correctly Twig doesn't support || and && operators, but requires or and and to be used respectively. I'd also use parentheses to denote the two statements more clearly although this isn't technically a requirement.

{%if ( fields | length > 0 ) or ( trans_fields | length > 0 ) %}

Expressions

Expressions can be used in {% blocks %} and ${ expressions }.

Operator    Description
==          Does the left expression equal the right expression?
+           Convert both arguments into a number and add them.
-           Convert both arguments into a number and substract them.
*           Convert both arguments into a number and multiply them.
/           Convert both arguments into a number and divide them.
%           Convert both arguments into a number and calculate the rest of the integer division.
~           Convert both arguments into a string and concatenate them.
or          True if the left or the right expression is true.
and         True if the left and the right expression is true.
not         Negate the expression.

For more complex operations, it may be best to wrap individual expressions in parentheses to avoid confusion:

{% if (foo and bar) or (fizz and (foo + bar == 3)) %}

You need to use background-image instead of backgroundImage. For example:

$(function() {
  $('.home').click(function() {
    $(this).css('background-image', 'url(images/tabs3.png)');
  });
}):

I dont know if you solved this issue, but i had same issue, if the instance is local you must check the permission to access the file, but if you are accessing from your computer to a server (remote access) you have to specify the path in the server, so that means to include the file in a server directory, that solved my case

example:

BULK INSERT Table
FROM 'C:\bulk\usuarios_prueba.csv' -- This is server path not local
WITH 
  (
     FIELDTERMINATOR =',',
     ROWTERMINATOR ='\n'
  );

1. Sessions are not RESTless
2. Do you mean that REST service for http-use only or I got smth wrong? Cookie-based session must be used only for own(!) http-based services! (It could be a problem to work with cookie, e.g. from Mobile/Console/Desktop/etc.)
3. if you provide RESTful service for 3d party developers, never use cookie-based session, use tokens instead to avoid the problems with security.

var option = driver.FindElement(By.Id("employmentType"));
        var selectElement = new SelectElement(option);
        Task.Delay(3000).Wait();
        selectElement.SelectByIndex(2);
        Console.Read();

Depends on the use case. But let's assume you want to do something useful with your "variable" types. The Swift switch statement is very powerful and can help you get the results you're looking for...

    let dd2 = ["x" : 9, "y" : "home9"]
    let dds = dd2.filter {
        let eIndex = "x"
        let eValue:Any = 9
        var r = false

        switch eValue {
        case let testString as String:
            r = $1 == testString
        case let testUInt as UInt:
            r = $1 == testUInt
        case let testInt as Int:
            r = $1 == testInt
        default:
            r = false
        }

        return r && $0 == eIndex
    }

In this case, have a simple dictionary that contains key/value pairs that can be UInt, Int or String. In the .filter() method on the dictionary, I need to make sure I test for the values correctly and only test for a String when it's a string, etc. The switch statement makes this simple and safe! By assigning 9 to the variable of type Any, it makes the switch for Int execute. Try changing it to:

   let eValue:Any = "home9"

..and try it again. This time it executes the as String case.

Modify your constructor to the following so that it calls the base class constructor properly:

public class MyExceptionClass : Exception
{
    public MyExceptionClass(string message, string extrainfo) : base(message)
    {
        //other stuff here
    }
}

Note that a constructor is not something that you can call anytime within a method. That's the reason you're getting errors in your call in the constructor body.

If they are two integers you can try a quick and dirty trick: Map<String, ?> using the key as i+"#"+j.

If the key i+"#"+j is the same as j+"#"+i try min(i,j)+"#"+max(i,j).

window.alert = null;
alert('test'); // fail
delete window.alert; // true
alert('test'); // win

window is an instance of DOMWindow, and by setting something to window.alert, the correct implementation is being "shadowed", i.e. when accessing alert it is first looking for it on the window object. Usually this is not found, and it then goes up the prototype chain to find the native implementation. However, when manually adding the alert property to window it finds it straight away and does not need to go up the prototype chain. Using delete window.alert you can remove the window own property and again expose the prototype implementation of alert. This may help explain:

window.hasOwnProperty('alert'); // false
window.alert = null;
window.hasOwnProperty('alert'); // true
delete window.alert;
window.hasOwnProperty('alert'); // false

It worked for me when I selected 'Use Host GPU' option under 'Emulation Options:'.

You can find the option under Edit window of the virtual device.

the issue is that a DataTemplate isn't part of an element its applied to it.

this means if you bind to the template you're binding to something that has no context.

however if you put a element inside the template then when that element is applied to the parent it gains a context and the binding then works

so this will not work

<DataTemplate >
    <DataTemplate.Resources>
        <CollectionViewSource x:Key="projects" Source="{Binding Projects}" >

but this works perfectly

<DataTemplate >
    <GroupBox Header="Projects">
        <GroupBox.Resources>
            <CollectionViewSource x:Key="projects" Source="{Binding Projects}" >

because after the datatemplate is applied the groupbox is placed in the parent and will have access to its Context

so all you have to do is remove the style from the template and move it into an element in the template

note that the context for a itemscontrol is the item not the control ie ComboBoxItem for ComboBox not the ComboBox itself in which case you should use the controls ItemContainerStyle instead

Symmetric Key Cryptography : Symmetric key uses the same key for encryption and decryption. The main challenge with this type of cryptography is the exchange of the secret key between the two parties sender and receiver.

Example : The following example uses symmetric key for encryption and decryption algorithm available as part of the Sun's JCE(Java Cryptography Extension). Sun JCE is has two layers, the crypto API layer and the provider layer.

DES (Data Encryption Standard) was a popular symmetric key algorithm. Presently DES is outdated and considered insecure. Triple DES and a stronger variant of DES. It is a symmetric-key block cipher. There are other algorithms like Blowfish, Twofish and AES(Advanced Encryption Standard). AES is the latest encryption standard over the DES.

Steps :

1. Add the Security Provider : We are using the SunJCE Provider that is available with the JDK.
2. Generate Secret Key : Use KeyGenerator and an algorithm to generate a secret key. We are using DESede.
3. Encode Text : For consistency across platform encode the plain text as byte using UTF-8 encoding.
4. Encrypt Text : Instantiate Cipher with ENCRYPT_MODE, use the secret key and encrypt the bytes.
5. Decrypt Text : Instantiate Cipher with DECRYPT_MODE, use the same secret key and decrypt the bytes.

All the above given steps and concept are same, we just replace algorithms.

        System.out.println("Decrypted Text After Decryption: " + decryptedText);
    }

    public static String encrypt(String plainText, SecretKey secretKey)
            throws Exception {
        byte[] plainTextByte = plainText.getBytes();

        Base64.Encoder encoder = Base64.getEncoder();
        String encryptedText = encoder.encodeToString(encryptedByte);
        return encryptedText;
    }

    public static String decrypt(String encryptedText, SecretKey secretKey)
            throws Exception {
        Base64.Decoder decoder = Base64.getDecoder();
        byte[] encryptedTextByte = decoder.decode(encryptedText);
        cipher.init(Cipher.DECRYPT_MODE, secretKey);
        byte[] decryptedByte = cipher.doFinal(encryptedTextByte);
        String decryptedText = new String(decryptedByte);
        return decryptedText;
    }
}

It seems to me, that it is by design that this file is empty.

A similar question has been asked here: https://stackoverflow.com/questions/2567432/ubuntu-apache-httpd-conf-or-apache2-conf

So, you should have a look for /etc/apache2/apache2.conf

These answers are all way too complicated!

The way he wrote the method is fine. The problem is where he invoked the method. He did not include parentheses after the method name, so the compiler thought he was trying to get a value from a variable instead of a method.

In Visual Basic and Delphi, those parentheses are optional, but in C#, they are required. So, to correct the last line of the original post:

Console.WriteLine("{0}", x.fullNameMethod());

Jupytext is nice to have in your toolchain for such conversions. It allows not only conversion from a notebook to a script, but you can go back again from the script to notebook as well. And even have that notebook produced in executed form.

jupytext --to py notebook.ipynb                 # convert notebook.ipynb to a .py file
jupytext --to notebook notebook.py              # convert notebook.py to an .ipynb file with no outputs
jupytext --to notebook --execute notebook.py    # convert notebook.py to an .ipynb file and run it 

If you have only one section, then the quickest and easiest way is to just set the Table View Style from "Plain" to "Grouped". (see image)

If you have more sections, you might need to set the header height to zero (depending on your/your customer's/your project manager's taste)

If you have more sections, and don't want to mess with the headers (even if it is just one line in the simplest case), then you need to set a UIView as a footer, as it was explained in the previous answers)

It means that:

• public - it can be called from anywhere
• static - it doesn't have any object state, so you can call it without instantiating an object
• void - it doesn't return anything

You'd think that the lack of a return means it isn't doing much, but it might be saving things in the database, for example.

The earlier version of the accepted answer (md5(uniqid(mt_rand(), true))) is insecure and only offers about 2^60 possible outputs -- well within the range of a brute force search in about a week's time for a low-budget attacker:

• mt_rand() is predictable (and only adds up to 31 bits of entropy)
• uniqid() only adds up to 29 bits of entropy
• md5() doesn't add entropy, it just mixes it deterministically

Since a 56-bit DES key can be brute-forced in about 24 hours, and an average case would have about 59 bits of entropy, we can calculate 2^59 / 2^56 = about 8 days. Depending on how this token verification is implemented, it might be possible to practically leak timing information and infer the first N bytes of a valid reset token.

Since the question is about "best practices" and opens with...

I want to generate identifier for forgot password

...we can infer that this token has implicit security requirements. And when you add security requirements to a random number generator, the best practice is to always use a cryptographically secure pseudorandom number generator (abbreviated CSPRNG).

Using a CSPRNG

In PHP 7, you can use bin2hex(random_bytes($n)) (where $n is an integer larger than 15).

In PHP 5, you can use random_compat to expose the same API.

Alternatively, bin2hex(mcrypt_create_iv($n, MCRYPT_DEV_URANDOM)) if you have ext/mcrypt installed. Another good one-liner is bin2hex(openssl_random_pseudo_bytes($n)).

Separating the Lookup from the Validator

Pulling from my previous work on secure "remember me" cookies in PHP, the only effective way to mitigate the aforementioned timing leak (typically introduced by the database query) is to separate the lookup from the validation.

If your table looks like this (MySQL)...

CREATE TABLE account_recovery (
    id INTEGER(11) UNSIGNED NOT NULL AUTO_INCREMENT 
    userid INTEGER(11) UNSIGNED NOT NULL,
    token CHAR(64),
    expires DATETIME,
    PRIMARY KEY(id)
);

... you need to add one more column, selector, like so:

CREATE TABLE account_recovery (
    id INTEGER(11) UNSIGNED NOT NULL AUTO_INCREMENT 
    userid INTEGER(11) UNSIGNED NOT NULL,
    selector CHAR(16),
    token CHAR(64),
    expires DATETIME,
    PRIMARY KEY(id),
    KEY(selector)
);

Use a CSPRNG When a password reset token is issued, send both values to the user, store the selector and a SHA-256 hash of the random token in the database. Use the selector to grab the hash and User ID, calculate the SHA-256 hash of the token the user provides with the one stored in the database using hash_equals().

Example Code

Generating a reset token in PHP 7 (or 5.6 with random_compat) with PDO:

$selector = bin2hex(random_bytes(8));
$token = random_bytes(32);

$urlToEmail = 'http://example.com/reset.php?'.http_build_query([
    'selector' => $selector,
    'validator' => bin2hex($token)
]);

$expires = new DateTime('NOW');
$expires->add(new DateInterval('PT01H')); // 1 hour

$stmt = $pdo->prepare("INSERT INTO account_recovery (userid, selector, token, expires) VALUES (:userid, :selector, :token, :expires);");
$stmt->execute([
    'userid' => $userId, // define this elsewhere!
    'selector' => $selector,
    'token' => hash('sha256', $token),
    'expires' => $expires->format('Y-m-d\TH:i:s')
]);

Verifying the user-provided reset token:

$stmt = $pdo->prepare("SELECT * FROM account_recovery WHERE selector = ? AND expires >= NOW()");
$stmt->execute([$selector]);
$results = $stmt->fetchAll(PDO::FETCH_ASSOC);
if (!empty($results)) {
    $calc = hash('sha256', hex2bin($validator));
    if (hash_equals($calc, $results[0]['token'])) {
        // The reset token is valid. Authenticate the user.
    }
    // Remove the token from the DB regardless of success or failure.
}

These code snippets are not complete solutions (I eschewed the input validation and framework integrations), but they should serve as an example of what to do.

You can either create a new Stage, add your controls into it or if you require the POPUP as Dialog box, then you may consider using DialogsFX or ControlsFX(Requires JavaFX8)

For creating a new Stage, you can use the following snippet

@Override
public void start(final Stage primaryStage) {
    Button btn = new Button();
    btn.setText("Open Dialog");
    btn.setOnAction(
        new EventHandler<ActionEvent>() {
            @Override
            public void handle(ActionEvent event) {
                final Stage dialog = new Stage();
                dialog.initModality(Modality.APPLICATION_MODAL);
                dialog.initOwner(primaryStage);
                VBox dialogVbox = new VBox(20);
                dialogVbox.getChildren().add(new Text("This is a Dialog"));
                Scene dialogScene = new Scene(dialogVbox, 300, 200);
                dialog.setScene(dialogScene);
                dialog.show();
            }
         });
    }

If you don't want it to be modal (block other windows), use:

dialog.initModality(Modality.NONE);

This means that you must declare strict mode by writing "use strict" at the beginning of the file or the function to use block-scope declarations.

EX:

function test(){
    "use strict";
    let a = 1;
} 

Concurrent signal assignment:

library ieee;
use ieee.std_logic_1164.all;

entity foo is
end;
architecture behave of foo is
    signal clk: std_logic := '0';
begin
CLOCK:
clk <=  '1' after 0.5 ns when clk = '0' else
        '0' after 0.5 ns when clk = '1';
end;

ghdl -a foo.vhdl
ghdl -r foo --stop-time=10ns --wave=foo.ghw
ghdl:info: simulation stopped by --stop-time
gtkwave foo.ghw

Simulators simulate processes and it would be transformed into the equivalent process to your process statement. Simulation time implies the use of wait for or after when driving events for sensitivity clauses or sensitivity lists.

You can try mas-cli (Mac Apple Store cli). Github project here

It would be

$ brew install mas
$ mas list
$ mas search Xcode
$ mas install <id> 

$ mas upgrade <id>

upd:

Had issues installing Xcode 12.2 in Big Sur. Solved them by entering into the App Store from the devs link.

https://developer.apple.com/download/release/

The shortest way to do that would be:

do {
    // Something
} while (*url);

Basically, *url will return the char at the first position in the array; since C strings are null-terminated, if the string is empty, its first position will be the character '\0', whose ASCII value is 0; since C logical statements treat every zero value as false, this loop will keep going while the first position of the string is non-null, that is, while the string is not empty.

Recommended readings if you want to understand this better:

• C strings: https://www.tutorialspoint.com/cprogramming/c_strings.htm
• C arrays: https://www.tutorialspoint.com/cprogramming/c_arrays.htm
• Relation between arrays and pointers: https://www.programiz.com/c-programming/c-pointers-arrays
• Logical operators: https://www.tutorialspoint.com/cprogramming/c_logical_operators.htm

the easiest way to do this is to wrap your sockets in ObjectInput/OutputStreams and send serialized java objects. you can create classes which contain the relevant data, and then you don't need to worry about the nitty gritty details of handling binary protocols. just make sure that you flush your object streams after you write each object "message".

just for additional info, If your apps is automatically run on emulator, right click on the project, Run As -> Run Configuration, then on the Run Configuration choose on the Manual. after that, if you run your apps you will be prompted to chose where you want to run your apps, there will be listed all the available device and emulator.

From my understanding, router.navigate is used to navigate relatively to current path. For eg : If our current path is abc.com/user, we want to navigate to the url : abc.com/user/10 for this scenario we can use router.navigate .

router.navigateByUrl() is used for absolute path navigation.

ie,

If we need to navigate to entirely different route in that case we can use router.navigateByUrl

For example if we need to navigate from abc.com/user to abc.com/assets, in this case we can use router.navigateByUrl()

Syntax :

router.navigateByUrl(' ---- String ----');

router.navigate([], {relativeTo: route})

The "0x" counts towards the eight character count. You need "%#010x".

Note that # does not append the 0x to 0 - the result will be 0000000000 - so you probably actually should just use "0x%08x" anyway.

You can try a list comp

>>> exampleSet = [{'type':'type1'},{'type':'type2'},{'type':'type2'}, {'type':'type3'}]
>>> keyValList = ['type2','type3']
>>> expectedResult = [d for d in exampleSet if d['type'] in keyValList]
>>> expectedResult
[{'type': 'type2'}, {'type': 'type2'}, {'type': 'type3'}]

Another way is by using filter

>>> list(filter(lambda d: d['type'] in keyValList, exampleSet))
[{'type': 'type2'}, {'type': 'type2'}, {'type': 'type3'}]

A MonkeyPatch is a piece of Python code which extends or modifies other code at runtime (typically at startup).

In this answer I choose to approach the "Simple Java AES encrypt/decrypt example" main theme and not the specific debugging question because I think this will profit most readers.

This is a simple summary of my blog post about AES encryption in Java so I recommend reading through it before implementing anything. I will however still provide a simple example to use and give some pointers what to watch out for.

In this example I will choose to use authenticated encryption with Galois/Counter Mode or GCM mode. The reason is that in most case you want integrity and authenticity in combination with confidentiality (read more in the blog).

AES-GCM Encryption/Decryption Tutorial

Here are the steps required to encrypt/decrypt with AES-GCM with the Java Cryptography Architecture (JCA). Do not mix with other examples, as subtle differences may make your code utterly insecure.

1. Create Key

As it depends on your use-case, I will assume the simplest case: a random secret key.

SecureRandom secureRandom = new SecureRandom();
byte[] key = new byte[16];
secureRandom.nextBytes(key);
SecretKey secretKey = SecretKeySpec(key, "AES");

Important:

• always use a strong pseudorandom number generator like SecureRandom
• use 16 byte / 128 bit long key (or more - but more is seldom needed)
• if you want a key derived from a user password, look into a password hash function (or KDF) with stretching property like PBKDF2 or bcrypt
• if you want a key derived from other sources, use a proper key derivation function (KDF) like HKDF (Java implementation here). Do not use simple cryptographic hashes for that (like SHA-256).

2. Create the Initialization Vector

An initialization vector (IV) is used so that the same secret key will create different cipher texts.

byte[] iv = new byte[12]; //NEVER REUSE THIS IV WITH SAME KEY
secureRandom.nextBytes(iv);

Important:

• never reuse the same IV with the same key (very important in GCM/CTR mode)
• the IV must be unique (ie. use random IV or a counter)
• the IV is not required to be secret
• always use a strong pseudorandom number generator like SecureRandom
• 12 byte IV is the correct choice for AES-GCM mode

3. Encrypt with IV and Key

final Cipher cipher = Cipher.getInstance("AES/GCM/NoPadding");
GCMParameterSpec parameterSpec = new GCMParameterSpec(128, iv); //128 bit auth tag length
cipher.init(Cipher.ENCRYPT_MODE, secretKey, parameterSpec);
byte[] cipherText = cipher.doFinal(plainText);

Important:

• use 16 byte / 128 bit authentication tag (used to verify integrity/authenticity)
• the authentication tag will be automatically appended to the cipher text (in the JCA implementation)
• since GCM behaves like a stream cipher, no padding is required
• use CipherInputStream when encrypting large chunks of data
• want additional (non-secret) data checked if it was changed? You may want to use associated data with cipher.updateAAD(associatedData); More here.

3. Serialize to Single Message

Just append IV and ciphertext. As stated above, the IV doesn't need to be secret.

ByteBuffer byteBuffer = ByteBuffer.allocate(iv.length + cipherText.length);
byteBuffer.put(iv);
byteBuffer.put(cipherText);
byte[] cipherMessage = byteBuffer.array();

Optionally encode with Base64 if you need a string representation. Either use Android's or Java 8's built-in implementation (do not use Apache Commons Codec - it's an awful implementation). Encoding is used to "convert" byte arrays to string representation to make it ASCII safe e.g.:

String base64CipherMessage = Base64.getEncoder().encodeToString(cipherMessage);

4. Prepare Decryption: Deserialize

If you have encoded the message, first decode it to byte array:

byte[] cipherMessage = Base64.getDecoder().decode(base64CipherMessage)

Important:

• be careful to validate input parameters, so to avoid denial of service attacks by allocating too much memory.

5. Decrypt

Initialize the cipher and set the same parameters as with the encryption:

final Cipher cipher = Cipher.getInstance("AES/GCM/NoPadding");
//use first 12 bytes for iv
AlgorithmParameterSpec gcmIv = new GCMParameterSpec(128, cipherMessage, 0, 12);
cipher.init(Cipher.DECRYPT_MODE, secretKey, gcmIv);
//use everything from 12 bytes on as ciphertext
byte[] plainText = cipher.doFinal(cipherMessage, 12, cipherMessage.length - 12);

Important:

• don't forget to add associated data with cipher.updateAAD(associatedData); if you added it during encryption.

A working code snippet can be found in this gist.

Note that most recent Android (SDK 21+) and Java (7+) implementations should have AES-GCM. Older versions may lack it. I still choose this mode, since it is easier to implement in addition to being more efficient compared to similar mode of Encrypt-then-Mac (with e.g. AES-CBC + HMAC). See this article on how to implement AES-CBC with HMAC.

I know this is an old question, but I thought I'd present one more solution that could be used if you'd like to avoid using named function expressions. (Not saying you should or should not avoid them, just presenting another solution)

  var fn = (function() {
    var innerFn = function(counter) {
      console.log(counter);

      if(counter > 0) {
        innerFn(counter-1);
      }
    };

    return innerFn;
  })();

  console.log("running fn");
  fn(3);

  var copyFn = fn;

  console.log("running copyFn");
  copyFn(3);

  fn = function() { console.log("done"); };

  console.log("fn after reassignment");
  fn(3);

  console.log("copyFn after reassignment of fn");
  copyFn(3);

You probably want to do the following,

const $ = window.$

to avoid it throwing linting error.

.zone() has been deprecated, and you should use utcOffset instead:

// for a timezone that is +7 UTC hours
moment(1369266934311).utcOffset(420).format('YYYY-MM-DD HH:mm')

I purchased Textmate because I liked it so much, one of the few apps I paid for. Other editors are just not worth it. If you are going for an IDE, eclipse or netbeans are great and free.

Try something like this:

@players.include?(p.name) ? false : true

To follow-up on Charles Bailey's answer, here's my git setup that's using p4merge (free cross-platform 3way merge tool); tested on msys Git (Windows) install:

git config --global merge.tool p4merge
git config --global mergetool.p4merge.cmd 'p4merge.exe \"$BASE\" \"$LOCAL\" \"$REMOTE\" \"$MERGED\"'

or, from a windows cmd.exe shell, the second line becomes :

git config --global mergetool.p4merge.cmd "p4merge.exe \"$BASE\" \"$LOCAL\" \"$REMOTE\" \"$MERGED\""

The changes (relative to Charles Bailey):

• added to global git config, i.e. valid for all git projects not just the current one
• the custom tool config value resides in "mergetool.[tool].cmd", not "merge.[tool].cmd" (silly me, spent an hour troubleshooting why git kept complaining about non-existing tool)
• added double quotes for all file names so that files with spaces can still be found by the merge tool (I tested this in msys Git from Powershell)
• note that by default Perforce will add its installation dir to PATH, thus no need to specify full path to p4merge in the command

Download: http://www.perforce.com/product/components/perforce-visual-merge-and-diff-tools

EDIT (Feb 2014)

As pointed out by @Gregory Pakosz, latest msys git now "natively" supports p4merge (tested on 1.8.5.2.msysgit.0).

You can display list of supported tools by running:

git mergetool --tool-help

You should see p4merge in either available or valid list. If not, please update your git.

If p4merge was listed as available, it is in your PATH and you only have to set merge.tool:

git config --global merge.tool p4merge

If it was listed as valid, you have to define mergetool.p4merge.path in addition to merge.tool:

git config --global mergetool.p4merge.path c:/Users/my-login/AppData/Local/Perforce/p4merge.exe

• The above is an example path when p4merge was installed for the current user, not system-wide (does not need admin rights or UAC elevation)
• Although ~ should expand to current user's home directory (so in theory the path should be ~/AppData/Local/Perforce/p4merge.exe), this did not work for me
• Even better would have been to take advantage of an environment variable (e.g. $LOCALAPPDATA/Perforce/p4merge.exe), git does not seem to be expanding environment variables for paths (if you know how to get this working, please let me know or update this answer)

From your comment:

this line DateTime Date = reader.GetDateTime(0); was throwing the exception

The first column is not a valid DateTime. Most likely, you have multiple columns in your table, and you're retrieving them all by running this query:

SELECT * from INFO

Replace it with a query that retrieves only the two columns you're interested in:

SELECT YOUR_DATE_COLUMN, YOUR_TIME_COLUMN from INFO

Then try reading the values again:

var Date = reader.GetDateTime(0);
var Time = reader.GetTimeSpan(1);  // equivalent to time(7) from your database

Or:

var Date = Convert.ToDateTime(reader["YOUR_DATE_COLUMN"]);
var Time = (TimeSpan)reader["YOUR_TIME_COLUMN"];

Try this:

div.topmenu-design ul
{
  display:block;
  width:600px; /* or whatever width value */
  margin:0px auto;
}

I just created a jQuery function to load an image using jQuerys Deferred Object which makes it very easy to react on load/error event:

$.fn.extend({
    loadImg: function(url, timeout) {
        // init deferred object
        var defer = $.Deferred(),
            $img = this,
            img = $img.get(0),
            timer = null;

        // define load and error events BEFORE setting the src
        // otherwise IE might fire the event before listening to it
        $img.load(function(e) {
            var that = this;
            // defer this check in order to let IE catch the right image size
            window.setTimeout(function() {
                // make sure the width and height are > 0
                ((that.width > 0 && that.height > 0) ? 
                    defer.resolveWith : 
                    defer.rejectWith)($img);
            }, 1);
        }).error(function(e) {
            defer.rejectWith($img);
        });

        // start loading the image
        img.src = url;

        // check if it's already in the cache
        if (img.complete) {
            defer.resolveWith($img);
        } else if (0 !== timeout) {
            // add a timeout, by default 15 seconds
            timer = window.setTimeout(function() {
                defer.rejectWith($img);
            }, timeout || 15000);
        }

        // return the promise of the deferred object
        return defer.promise().always(function() {
            // stop the timeout timer
            window.clearTimeout(timer);
            timer = null;
            // unbind the load and error event
            this.off("load error");
        });
    }
});

Usage:

var image = $('<img />').loadImg('http://www.google.com/intl/en_com/images/srpr/logo3w.png')
.done(function() {
    alert('image loaded');
    $('body').append(this);
}).fail(function(){
    alert('image failed');
});

See it working at: http://jsfiddle.net/roberkules/AdWZj/

<br /> works for me

So...

String body = String.Format(@"New user: 
 <br /> Name: {0}
 <br /> Email: {1}
 <br /> Phone: {2}", Name, Email, Phone);

Produces...

New user:
Name: Name
Email: Email
Phone: Phone

Here is an example:

List<String> names;
names.add("toto");
names.add("Lala");
names.add("papa");
int index = names.indexOf("papa"); // index = 2

Your second version is less efficient because it creates an extra string object when there is simply no need to do so.

Immutability means that your first version behaves the way you expect and is thus the approach to be preferred.

I have wondered the same thing. Basically it appears that the html spec has different content types for html and form data. Json only has a single content type.

According to the spec, a POST of json data should have the content-type:
application/json

Relevant portion of the HTML spec

6.7 Content types (MIME types)
...
Examples of content types include "text/html", "image/png", "image/gif", "video/mpeg", "text/css", and "audio/basic".

17.13.4 Form content types
...
application/x-www-form-urlencoded
This is the default content type. Forms submitted with this content type must be encoded as follows

Relevant portion of the JSON spec

1. IANA Considerations
   The MIME media type for JSON text is application/json.

The PDFMiner package has changed since codeape posted.

EDIT (again):

PDFMiner has been updated again in version 20100213

You can check the version you have installed with the following:

>>> import pdfminer

Here's the updated version (with comments on what I changed/added):

Edit (yet again):

Here is an update for the latest version in pypi, 20100619p1. In short I replaced LTTextItem with LTChar and passed an instance of LAParams to the CsvConverter constructor.

Okay, first a few terms slightly oversimplified.

In git, a tag (like many other things) is what's called a treeish. It's a way of referring to a point in in the history of the project. Treeishes can be a tag, a commit, a date specifier, an ordinal specifier or many other things.

Now a branch is just like a tag but is movable. When you are "on" a branch and make a commit, the branch is moved to the new commit you made indicating it's current position.

Your HEAD is pointer to a branch which is considered "current". Usually when you clone a repository, HEAD will point to master which in turn will point to a commit. When you then do something like git checkout experimental, you switch the HEAD to point to the experimental branch which might point to a different commit.

Now the explanation.

When you do a git checkout v2.0, you are switching to a commit that is not pointed to by a branch. The HEAD is now "detached" and not pointing to a branch. If you decide to make a commit now (as you may), there's no branch pointer to update to track this commit. Switching back to another commit will make you lose this new commit you've made. That's what the message is telling you.

Usually, what you can do is to say git checkout -b v2.0-fixes v2.0. This will create a new branch pointer at the commit pointed to by the treeish v2.0 (a tag in this case) and then shift your HEAD to point to that. Now, if you make commits, it will be possible to track them (using the v2.0-fixes branch) and you can work like you usually would. There's nothing "wrong" with what you've done especially if you just want to take a look at the v2.0 code. If however, you want to make any alterations there which you want to track, you'll need a branch.

You should spend some time understanding the whole DAG model of git. It's surprisingly simple and makes all the commands quite clear.

Well, it actually looks like the warning is telling you what to do.

As part of sklearn.pipeline stages' uniform interfaces, as a rule of thumb:

• when you see X, it should be an np.array with two dimensions

• when you see y, it should be an np.array with a single dimension.

Here, therefore, you should consider the following:

temp = [1,2,3,4,5,5,6,....................,7]
# This makes it into a 2d array
temp = np.array(temp).reshape((len(temp), 1))
temp = scaler.transform(temp)

In java you can do some thing like:

if(driver.getTitle().contains("some expected text"))
    //Pass
    System.out.println("Page title contains \"some expected text\" ");
else
    //Fail
    System.out.println("Page title doesn't contains \"some expected text\" ");

from item in db.vw_Dropship_OrderItems
    where (listStatus != null ? listStatus.Contains(item.StatusCode) : true) &&
    (listMerchants != null ? listMerchants.Contains(item.MerchantId) : true)
    select item;

Might give strange behavior if both listMerchants and listStatus are both null.

You can use .toFixed(0) to remove complete decimal part or provide the number in arguments upto which you want decimal to be truncated.

Note: toFixed will convert the number to string.

This example selects a new Range of Cells defined by the current cell to a cell 5 to the right.

Note that .Offset takes arguments of Offset(row, columns) and can be quite useful.

Sub testForStackOverflow()
    Range(ActiveCell, ActiveCell.Offset(0, 5)).Copy
End Sub

If you set up a click binding in Knockout the event is passed as the second parameter. You can use the event to obtain the element that the click occurred on and perform whatever action you want.

Here is a fiddle that demonstrates: http://jsfiddle.net/jearles/xSKyR/

Alternatively, you could create your own custom binding, which will receive the element it is bound to as the first parameter. On init you could attach your own click event handler to do any actions you wish.

http://knockoutjs.com/documentation/custom-bindings.html

<div>
    <button data-bind="click: clickMe">Click Me!</button>
</div>

var ViewModel = function() {
    var self = this;
    self.clickMe = function(data,event) {

      var target = event.target || event.srcElement;

      if (target.nodeType == 3) // defeat Safari bug
        target = target.parentNode;

      target.parentNode.innerHTML = "something";
    }
}

ko.applyBindings(new ViewModel());

There are legitimate technical reasons to want a generalized solution to the problem of bash alias not having a mechanism to take a reposition arbitrary arguments. One reason is if the command you wish to execute would be adversely affected by the changes to the environment that result from executing a function. In all other cases, functions should be used.

What recently compelled me to attempt a solution to this is that I wanted to create some abbreviated commands for printing the definitions of variables and functions. So I wrote some functions for that purpose. However, there are certain variables which are (or may be) changed by a function call itself. Among them are:

FUNCNAME BASH_SOURCE BASH_LINENO BASH_ARGC BASH_ARGV

The basic command I had been using (in a function) to print variable defns. in the form output by the set command was:

sv () { set | grep --color=never -- "^$1=.*"; }

E.g.:

> V=voodoo
sv V
V=voodoo

Problem: This won't print the definitions of the variables mentioned above as they are in the current context, e.g., if in an interactive shell prompt (or not in any function calls), FUNCNAME isn't defined. But my function tells me the wrong information:

> sv FUNCNAME
FUNCNAME=([0]="sv")

One solution I came up with has been mentioned by others in other posts on this topic. For this specific command to print variable defns., and which requires only one argument, I did this:

alias asv='(grep -- "^$(cat -)=.*" <(set)) <<<'

Which gives the correct output (none), and result status (false):

> asv FUNCNAME
> echo $?
1

However, I still felt compelled to find a solution that works for arbitrary numbers of arguments.

A General Solution To Passing Arbitrary Arguments To A Bash Aliased Command:

# (I put this code in a file "alias-arg.sh"):

# cmd [arg1 ...] – an experimental command that optionally takes args,
# which are printed as "cmd(arg1 ...)"
#
# Also sets global variable "CMD_DONE" to "true".
#
cmd () { echo "cmd($@)"; declare -g CMD_DONE=true; }

# Now set up an alias "ac2" that passes to cmd two arguments placed
# after the alias, but passes them to cmd with their order reversed:
#
# ac2 cmd_arg2 cmd_arg1 – calls "cmd" as: "cmd cmd_arg1 cmd_arg2"
#
alias ac2='
    # Set up cmd to be execed after f() finishes:
    #
    trap '\''cmd "${CMD_ARGV[1]}" "${CMD_ARGV[0]}"'\'' SIGUSR1;
    #        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    #       (^This is the actually execed command^)
    #
    # f [arg0 arg1 ...] – acquires args and sets up trap to run cmd:
    f () {
        declare -ag CMD_ARGV=("$@");  # array to give args to cmd
        kill -SIGUSR1 $$;             # this causes cmd to be run
        trap SIGUSR1;                 # unset the trap for SIGUSR1
        unset CMD_ARGV;               # clean up env...
        unset f;                      # incl. this function!
    };
    f'  # Finally, exec f, which will receive the args following "ac2".

E.g.:

> . alias-arg.sh
> ac2 one two
cmd(two one)
>
> # Check to see that command run via trap affects this environment:
> asv CMD_DONE
CMD_DONE=true

A nice thing about this solution is that all the special tricks used to handle positional parameters (arguments) to commands will work when composing the trapped command. The only difference is that array syntax must be used.

E.g.,

If you want "$@", use "${CMD_ARGV[@]}".

If you want "$#", use "${#CMD_ARGV[@]}".

Etc.

It took us a day to resolve this problem. The solution is forcing your webservice to use version 11.0.0 in your web.config file.

Use the random module: http://docs.python.org/library/random.html

import random
random.sample(set([1, 2, 3, 4, 5, 6]), 2)

This samples the two values without replacement (so the two values are different).

I had to use the "=" binding instead of "&" because that was not working. Strange behavior.

There are non-obvious memory retention issues to take into account here. Since a non-static inner class maintains an implicit reference to it's 'outer' class, if an instance of the inner class is strongly referenced, then the outer instance is strongly referenced too. This can lead to some head-scratching when the outer class is not garbage collected, even though it appears that nothing references it.

All other answers here depends on adding code the the notebook(!)

In my opinion is bad practice to hardcode a specific path into the notebook code, or otherwise depend on the location, since this makes it really hard to refactor you code later on. Instead I would recommend you to add the root project folder to PYTHONPATH when starting up your Jupyter notebook server, either directly from the project folder like so

env PYTHONPATH=`pwd` jupyter notebook

or if you are starting it up from somewhere else, use the absolute path like so

env PYTHONPATH=/Users/foo/bar/project/ jupyter notebook

First Open The Sublime Text 2.

And top menu bar on select the Preferences.

And than select the Key Bindings -User.

And than put this code,

[
    { "keys": ["ctrl+shift+c"], "command": "toggle_comment", "args": { "block": false } },

    { "keys": ["ctrl+shift+c"], "command": "toggle_comment", "args": { "block": true } }
]

I use Ctrl+Shift+C, You also different short cut key use.

You can use this function, ORACLE DB

 public string getMaximumSequenceOfUser(string columnName, string tableName, string username)
    {
        string result = "";
        var query = string.Format("Select MAX ({0})from {1} where CREATED_BY = {2}", columnName, tableName, username.ToLower());

        OracleConnection conn = new OracleConnection(_context.Database.Connection.ConnectionString);
        OracleCommand cmd = new OracleCommand(query, conn);
        try
        {
            conn.Open();
            OracleDataReader dr = cmd.ExecuteReader();
            dr.Read();
            result = dr[0].ToString();
            dr.Dispose();
        }
        finally
        {
            conn.Close();
        }
        return result;
    }

Just wanted to add that when using numbers for values with the css method you have to add them outside the apostrophe and then add the CSS unit in apostrophes.

$('.block').css('width',50 + '%');

or

var $block = $('.block')    

$block.css({ 'width': 50 + '%', 'height': 4 + 'em', 'background': '#FFDAB9' });

You don't need JavaScript to choose your default submit button or input. You just need to mark it up with type="submit", and the other buttons mark them with type="button". In your example:

<button type="button" onclick="return myFunc1()">Button 1</button>
<input type="submit" name="go" value="Submit"/>

New function "across" was introduced in dplyr version 1.0.0. The new function will supersede scoped variables (_if, _at, _all). Here's the official documentation

library(dplyr)
bob <- bob %>% 
       mutate(across(where(is.factor), as.character))

There is a (somewhat) related question on StackOverflow:

• Showing an image with pylab.imshow()

Here the problem was that an array of shape (nx,ny,1) is still considered a 3D array, and must be squeezed or sliced into a 2D array.

More generally, the reason for the Exception

TypeError: Invalid dimensions for image data

is shown here: matplotlib.pyplot.imshow() needs a 2D array, or a 3D array with the third dimension being of shape 3 or 4!

You can easily check this with (these checks are done by imshow, this function is only meant to give a more specific message in case it's not a valid input):

from __future__ import print_function
import numpy as np

def valid_imshow_data(data):
    data = np.asarray(data)
    if data.ndim == 2:
        return True
    elif data.ndim == 3:
        if 3 <= data.shape[2] <= 4:
            return True
        else:
            print('The "data" has 3 dimensions but the last dimension '
                  'must have a length of 3 (RGB) or 4 (RGBA), not "{}".'
                  ''.format(data.shape[2]))
            return False
    else:
        print('To visualize an image the data must be 2 dimensional or '
              '3 dimensional, not "{}".'
              ''.format(data.ndim))
        return False

In your case:

>>> new_SN_map = np.array([1,2,3])
>>> valid_imshow_data(new_SN_map)
To visualize an image the data must be 2 dimensional or 3 dimensional, not "1".
False

The np.asarray is what is done internally by matplotlib.pyplot.imshow so it's generally best you do it too. If you have a numpy array it's obsolete but if not (for example a list) it's necessary.

In your specific case you got a 1D array, so you need to add a dimension with np.expand_dims()

import matplotlib.pyplot as plt
a = np.array([1,2,3,4,5])
a = np.expand_dims(a, axis=0)  # or axis=1
plt.imshow(a)
plt.show()

or just use something that accepts 1D arrays like plot:

a = np.array([1,2,3,4,5])
plt.plot(a)
plt.show()

Happy to Help. by RTTSS.

The reason #2 fails is because sys.modules['module'] does not exist (the import routine has its own scope, and cannot see the module local name), and there's no module module or package on-disk. Note that you can separate multiple imported names by commas.

from package.subpackage.module import attribute1, attribute2, attribute3

Also:

from package.subpackage import module
print module.attribute1

From my perspective, the fastest way to achieve what you're looking for is to change "Start in" value.

To do that, right-click on git-bash.exe, go to Properties and change Start In value to the folder you want.

Is there a way to have placeholders, like ? for column names? For example SELECT ? FROM TABLEA GROUP BY ?

Use dynamic query as below:

String queryString = "SELECT "+ colName+ " FROM TABLEA GROUP BY "+ colName;

If I want to simply run the above query and get a List what is the best way?

List<String> data = getJdbcTemplate().query(query, new RowMapper<String>(){
                            public String mapRow(ResultSet rs, int rowNum) 
                                                         throws SQLException {
                                    return rs.getString(1);
                            }
                       });

EDIT: To Stop SQL Injection, check for non word characters in the colName as :

          Pattern pattern = Pattern.compile("\\W");
          if(pattern.matcher(str).find()){
               //throw exception as invalid column name
          }

Yes, use spellcheck="false", as defined by HTML5, for example:

<textarea spellcheck="false">
    ...
</textarea>

This is how I managed to do what I was trying to do:

[Test]
public void TransferHandlesDisconnect()
{
    // ... set up config here
    var methodTester = new Mock<Transfer>(configInfo);
    methodTester.CallBase = true;
    methodTester
        .Setup(m => 
            m.GetFile(
                It.IsAny<IFileConnection>(), 
                It.IsAny<string>(), 
                It.IsAny<string>()
            ))
        .Throws<System.IO.IOException>();

    methodTester.Object.TransferFiles("foo1", "foo2");
    Assert.IsTrue(methodTester.Object.Status == TransferStatus.TransferInterrupted);
}

If there is a problem with this method, I would like to know; the other answers suggest I am doing this wrong, but this was exactly what I was trying to do.

I'm not very advanced in AngularJS, but my solution would be to use a simple JS class for you cart (in the sense of coffee script) that extend Array.

The beauty of AngularJS is that you can pass you "model" object with ng-click like shown below.

I don't understand the advantage of using a factory, as I find it less pretty that a CoffeeScript class.

My solution could be transformed in a Service, for reusable purpose. But otherwise I don't see any advantage of using tools like factory or service.

class Basket extends Array
  constructor: ->

  add: (item) ->
    @push(item)

  remove: (item) ->
    index = @indexOf(item)
    @.splice(index, 1)

  contains: (item) ->
    @indexOf(item) isnt -1

  indexOf: (item) ->
    indexOf = -1
    @.forEach (stored_item, index) ->
      if (item.id is stored_item.id)
        indexOf = index
    return indexOf

Then you initialize this in your controller and create a function for that action:

 $scope.basket = new Basket()
 $scope.addItemToBasket = (item) ->
   $scope.basket.add(item)

Finally you set up a ng-click to an anchor, here you pass your object (retreived from the database as JSON object) to the function:

li ng-repeat="item in items"
  a href="#" ng-click="addItemToBasket(item)" 

I see kind of programming olympiad here. One more tricky one-line solution:

b = (function(){ a=b; return arguments[0]; })(a);

Go into the mysql data directory and run du -h --max-depth=1 | grep databasename

I implemented access using the following

class D(Enum):
    x = 1
    y = 2

    def __str__(self):
        return '%s' % self.value

now I can just do

print(D.x) to get 1 as result.

You can also use self.name in case you wanted to print x instead of 1.

You are using a very old version of curl. My guess is that you run into the bug described 6 years ago. Fix is to update your curl.

SOLUTIONS

1. Sometimes the project is created before installing g++. So install g++ first and then recreate your project. This worked for me.
2. Paste the following line in CMakeCache.txt: CMAKE_CXX_COMPILER:FILEPATH=/usr/bin/c++

Note the path to g++ depends on OS. I have used my fedora path obtained using which g++

If your problem is related to showing Big Image i.e. if you are sending push notification with an image from firebase console and it displays the image only if the app in the foreground. The solution for this problem is to send a push message with only data field. Something like this:

{ "data": { "image": "https://static.pexels.com/photos/4825/red-love-romantic-flowers.jpg", "message": "Firebase Push Message Using API" "AnotherActivity": "True" }, "to" : "device id Or Device token" }

That is, you are referencing an image, but instead of providing an external url, the png image data is in the url itself, embedded in the style sheet. data:image/png;base64 tells the browser that the data is inline, is a png image and is in this case base64 encoded. The encoding is needed because png images can contain bytes that are invalid inside a HTML document (or within the HTTP protocol even).

If you already have the string, you can use this function:

bool isNumber( const string& s )
{
  bool hitDecimal=0;
  for( char c : s )
  {
    if( c=='.' && !hitDecimal ) // 2 '.' in string mean invalid
      hitDecimal=1; // first hit here, we forgive and skip
    else if( !isdigit( c ) ) 
      return 0 ; // not ., not 
  }
  return 1 ;
}

What you can do is set specific width and height to your iframe (for example these could be equal to your window dimensions) and then applying a scale transformation to it. The scale value will be the ratio between your window width and the dimension you wanted to set to your iframe.

E.g.

<iframe width="1024" height="768" src="http://www.bbc.com" style="-webkit-transform:scale(0.5);-moz-transform-scale(0.5);"></iframe>

I think you mean the active state

 button:active{
  //some styling
 }

These are all the possible pseudo states a link can have in CSS:

a:link {color:#FF0000;}    /* unvisited link, same as regular 'a' */
a:hover {color:#FF00FF;}   /* mouse over link */
a:focus {color:#0000FF;}   /* link has focus */
a:active {color:#0000FF;}  /* selected link */
a:visited {color:#00FF00;} /* visited link */

In all that cases, only works in Chrome and IE, I added the following code to solve that:

var key = (window.event) ? e.keyCode : e.which;

and I tested the key value on if keycode equals 13

    $('body').on('keydown', 'input, select, textarea', function (e) {
    var self = $(this)
      , form = self.parents('form:eq(0)')
      , focusable
      , next
    ;

    var key = (window.event) ? e.keyCode : e.which;

    if (key == 13) {
        focusable = form.find('input,a,select,button,textarea').filter(':visible');
        next = focusable.eq(focusable.index(this) + 1);
        if (next.length) {
            next.focus();
        } else {
            focusable.click();
        }
        return false;
    }
});

Shortest way I am using:

$secure_connection = !empty($_SERVER['HTTPS']);

If if https is used, then $secure_connection is true.

I entirely agree that goto is poor poor coding, but no one has actually answered the question. There is in fact a goto module for Python (though it was released as an April fool joke and is not recommended to be used, it does work).

I know I'm late to this party, but the simplest way to hot encode a dataframe in an automated way is to use this function:

def hot_encode(df):
    obj_df = df.select_dtypes(include=['object'])
    return pd.get_dummies(df, columns=obj_df.columns).values

position: absolute will remove it from the layout flow and should solve your problem - the element will remain in the DOM but won't affect others.

This is sort of coming at the question from the other end but I thought I'd throw it in as I really had to dig on the internet to find this out.

There is a lot of stuff about how to check roles but not much saying what you are actually checking when you say hasRole("blah")

HasRole checks the granted authorities for the currently authenticated principal

So really when you see hasRole("blah") really means hasAuthority("blah").

In the case I've seen, you do this with a class that Implements UserDetails which defines a method called getAuthorities. In this you'll basically add some new SimpleGrantedAuthority("some name") to a list based on some logic. The names in this list are the things checked by the hasRole statements.

I guess in this context the UserDetails object is the currently authenticated principal. There's some magic that happens in and around authentication providers and more specifically the authentication-manager that makes this happen.

There is an implementation in my TypeScript utilities based on JavaScript GUID generators.

Here is the code:

class Guid {_x000D_
  static newGuid() {_x000D_
    return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function(c) {_x000D_
      var r = Math.random() * 16 | 0,_x000D_
        v = c == 'x' ? r : (r & 0x3 | 0x8);_x000D_
      return v.toString(16);_x000D_
    });_x000D_
  }_x000D_
}_x000D_
_x000D_
// Example of a bunch of GUIDs_x000D_
for (var i = 0; i < 100; i++) {_x000D_
  var id = Guid.newGuid();_x000D_
  console.log(id);_x000D_
}

Please note the following:

C# GUIDs are guaranteed to be unique. This solution is very likely to be unique. There is a huge gap between "very likely" and "guaranteed" and you don't want to fall through this gap.

JavaScript-generated GUIDs are great to use as a temporary key that you use while waiting for a server to respond, but I wouldn't necessarily trust them as the primary key in a database. If you are going to rely on a JavaScript-generated GUID, I would be tempted to check a register each time a GUID is created to ensure you haven't got a duplicate (an issue that has come up in the Chrome browser in some cases).

In my opinion the best approach to achieve this by using the filter method as it's meaningless to return in a forEach block; for an example on your snippet:

// Fetch all objects in SomeElements collection
var elementsCollection = SomeElements.find();
elementsCollection
.filter(function(element) {
  return element.shouldBeProcessed;
})
.forEach(function(element){
  doSomeLengthyOperation();
});

This will narrow down your elementsCollection and just keep the filtred elements that should be processed.

Simple Example to understand how to access elements in the dictionary:-

Create a Dictionary

d = {'dog' : 'bark', 'cat' : 'meow' } 
print(d.get('cat'))
print(d.get('lion'))
print(d.get('lion', 'Not in the dictionary'))
print(d.get('lion', 'NA'))
print(d.get('dog', 'NA'))

I was also facing the same problem. To fix this to the following steps.

1. open Javaws from cmd runnig javaws -viewer command. A new window will open
2. Select the jnlp file which you want and click the run button.
3. Close the javaws viewer window.

Write it as a one-liner:

figure('position', [0, 0, 200, 500])  % create new figure with specified size  

This should do the trick. Also read the documentation of the shutil module to choose the function that fits your needs (shutil.copy(), shutil.copy2(), shutil.copyfile() or shutil.move()).

import glob, os, shutil

source_dir = '/path/to/dir/with/files' #Path where your files are at the moment
dst = '/path/to/dir/for/new/files' #Path you want to move your files to
files = glob.iglob(os.path.join(source_dir, "*.txt"))
for file in files:
    if os.path.isfile(file):
        shutil.copy2(file, dst)

There is a simple work around. The alert only comes up when you have a large amount of data in your clipboard. Just copy a random cell before you close the workbook and it won't show up anymore!

Try writing the following batch file and executing it:

Echo one
cmd
Echo two
cmd
Echo three
cmd

Only the first two lines get executed. But if you type "exit" at the command prompt, the next two lines are processed. It's a shell loading another.

To be sure that this is not what is happening in your script, just type "exit" when the first command ends.

I have not seen any option in Microsoft SQL Server Management Studio 2012 to-date that will do that.

I am sure you can write something in T-SQL given the time.

Check out TOAD from QUEST - now owned by DELL.

http://www.toadworld.com/products/toad-for-oracle/f/10/t/9778.aspx

Choose Insert Statement format
Be sure to check “selected rows only”

Nice thing about toad, it works with both SQL server and Oracle. If you have to work with both, it is a good investment.

The Android Device Monitor application available under sdk/tools/monitor has a logcat option to filter 'by Application Name' where you enter the application package name.

My understanding is that this question is better answered over in this post.

But briefly, the answer to the OP with this method is simply:

s1 = pd.merge(df1, df2, how='inner', on=['user_id'])

Which gives s1 with 5 columns: user_id and the other two columns from each of df1 and df2.
