Programs & Examples On #Entitycollection

If you really want to use Deleted, you'd have to make your foreign keys nullable, but then you'd end up with orphaned records (which is one of the main reasons you shouldn't be doing that in the first place). So just use Remove()

ObjectContext.DeleteObject(entity) marks the entity as Deleted in the context. (It's EntityState is Deleted after that.) If you call SaveChanges afterwards EF sends a SQL DELETE statement to the database. If no referential constraints in the database are violated the entity will be deleted, otherwise an exception is thrown.

EntityCollection.Remove(childEntity) marks the relationship between parent and childEntity as Deleted. If the childEntity itself is deleted from the database and what exactly happens when you call SaveChanges depends on the kind of relationship between the two:

A thing worth noting is that setting .State = EntityState.Deleted does not trigger automatically detected change. (archive)

I resolved this by adding @Transactional to the base/generic Hibernate DAO implementation class (the parent class which implements the saveOrUpdate() method inherited by the DAO I use in the main program), i.e. the @Transactional needs to be specified on the actual class which implements the method. My assumption was instead that if I declared @Transactional on the child class then it included all of the methods that were inherited by the child class. However it seems that the @Transactional annotation only applies to methods implemented within a class and not to methods inherited by a class.

Seems like a bad way to do it (creating two correlated lists) but I'm assuming you have your reasons.

I'd parse the JSON string (which has a typo in your example, it's missing a comma between the two objects) into a strongly-typed object and then use a couple of LINQ queries to get the two lists.

void Main()
{
    string json = "{\"People\":[{\"FirstName\":\"Hans\",\"LastName\":\"Olo\"},{\"FirstName\":\"Jimmy\",\"LastName\":\"Crackedcorn\"}]}";

    var result = JsonConvert.DeserializeObject<RootObject>(json);

    var firstNames = result.People.Select (p => p.FirstName).ToList();
    var lastNames = result.People.Select (p => p.LastName).ToList();
}

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

public class RootObject
{
    public List<Person> People { get; set; }
}

r = list(qs[:1])
if r:
  return r[0]
return None

For those who are interested, here is my implementation extending MBO's original answer (written against rails 4.2.4, ruby 2.1.5).

class ApplicationController < ActionController::Base
  after_filter :set_return_to_location

  REDIRECT_CONTROLLER_BLACKLIST = %w(
    sessions
    user_sessions
    ...
    etc.
  )

  ...

  def set_return_to_location
    return unless request.get?
    return unless request.format.html?
    return unless %w(show index edit).include?(params[:action])
    return if REDIRECT_CONTROLLER_BLACKLIST.include?(controller_name)
    session[:return_to] = request.fullpath
  end

  def redirect_back_or_default(default_path = root_path)
    redirect_to(
      session[:return_to].present? && session[:return_to] != request.fullpath ?
        session[:return_to] : default_path
    )
  end
end

Use setResizable on your JFrame

yourFrame.setResizable(false);

But extending JFrame is generally a bad idea.

The datetime format actually that runs on sql server is

yyyy-mm-dd hh:MM:ss

You can put conditionals inside tags. Try:

ng-class="{true:'active',false:'disable'}[list_status=='show']"

dataset <- matrix(sample(c(NA, 1:5), 25, replace = TRUE), 5);
data <- as.data.frame(dataset)

[,1] [,2] [,3] [,4] [,5] 
[1,]    2    3    5    5    4
[2,]    2    4    3    2    4
[3,]    2   NA   NA   NA    2
[4,]    2    3   NA    5    5
[5,]    2    3    2    2    3

data[is.na(data)] <- 0

package com.dataload;

    public class insertCSV 
    {
        public static void main(String args[])
        {
            ApplicationContext context =
        new ClassPathXmlApplicationContext("applicationcontext.xml");


            // retrieve configured instance
            JobLauncher launcher = context.getBean("laucher", JobLauncher.class);
            Job job = context.getBean("job", Job.class);
            JobParameters jobParameters = context.getBean("jobParameters", JobParameters.class);
        }
    }

Use the Maven debug option, ie mvn -X :

Apache Maven 3.0.3 (r1075438; 2011-02-28 18:31:09+0100)
Maven home: /usr/java/apache-maven-3.0.3
Java version: 1.6.0_12, vendor: Sun Microsystems Inc.
Java home: /usr/java/jdk1.6.0_12/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "2.6.32-32-generic", arch: "i386", family: "unix"
[INFO] Error stacktraces are turned on.
[DEBUG] Reading global settings from /usr/java/apache-maven-3.0.3/conf/settings.xml
[DEBUG] Reading user settings from /home/myhome/.m2/settings.xml
...

In this output, you can see that the settings.xml is loaded from /home/myhome/.m2/settings.xml.

In percentage :

$('.your-class').click(function (e){
    var $this = $(this); // or use $(e.target) in some cases;
    var offset = $this.offset();
    var width = $this.width();
    var height = $this.height();
    var posX = offset.left;
    var posY = offset.top;
    var x = e.pageX-posX;
        x = parseInt(x/width*100,10);
        x = x<0?0:x;
        x = x>100?100:x;
    var y = e.pageY-posY;
        y = parseInt(y/height*100,10);
        y = y<0?0:y;
        y = y>100?100:y;
    console.log(x+'% '+y+'%');
});

If you need the space for the purpose of later concatenating it with other strings, then you can use the string formatting approach of adding arguments to your string definition:

<string name="error_">Error: %s</string>

Then for format the string (eg if you have an error returned by the server, otherwise use getString(R.string.string_resource_example)):

String message = context.getString(R.string.error_, "Server error message here")

Which results in:

Error: Server error message here

In 1.3.5 :

var clientIP = socket.handshake.headers.host;

I also encountered this mongoose error CastError: Cast to ObjectId failed for value \"583fe2c488cf652d4c6b45d1\" at path \"_id\" for model User

So I run npm list command to verify the mongodb and mongoose version in my local. Heres the report: ......
......
+-- [email protected]
+-- [email protected]
.....

It seems there's an issue on this mongodb version so what I did is I uninstall and try to use different version such as 2.2.16

$ npm uninstall mongodb, it will delete the mongodb from your node_modules directory. After that install the lower version of mongodb.
$ npm install [email protected]
Finally, I restart the app and the CastError is gone!!

Here is how I did it recently. Not perfect semantically, but gets the job done.

<div class="container" style="position: relative">
<img style="z-index: 32; left: 8px; position: relative;" alt="bottom image" src="images/bottom-image.jpg">
<div style="z-index: 100; left: 72px; position: absolute; top: 39px">
<img alt="top image" src="images/top-image.jpg"></div></div>

You should use a loop.

Here are two versions benchmarked by calculating the factorial of 100 for 10.000 times.

Recursive

function rFact(num)
{
    if (num === 0)
      { return 1; }
    else
      { return num * rFact( num - 1 ); }
}

Iterative

function sFact(num)
{
    var rval=1;
    for (var i = 2; i <= num; i++)
        rval = rval * i;
    return rval;
}

Live at : http://jsfiddle.net/xMpTv/

My results show:
- Recursive ~ 150 milliseconds
- Iterative ~ 5 milliseconds..

The first question you need to ask is whether you really need the ID to be random. Sometime, sequential IDs are good enough.

Now, if you do need it to be random, we first note a generated sequence of numbers that contain no duplicates can not be called random. :p Now that we get that out of the way, the fastest way to do this is to have a Hashtable or HashMap containing all the IDs already generated. Whenever a new ID is generated, check it against the hashtable, re-generate if the ID already occurs. This will generally work well if the number of students is much less than the range of the IDs. If not, you're in deeper trouble as the probability of needing to regenerate an ID increases, P(generate new ID) = number_of_id_already_generated / number_of_all_possible_ids. In this case, check back the first paragraph (do you need the ID to be random?).

Hope this helps.

There are a couple of things to check:

• In FireBug, see if there are any loading errors that would indicate that your script is badly formatted and the functions do not get registered.
• You can also try typing "proceedToSecond" into the FireBug console to see if the function gets defined
• One thing you may try is removing the space around the @type attribute to the script tag: it should be <script type="text/javascript"> instead of <script type = "text/javascript">

If you paste the listing into your word processor instead of Notepad, (since each file name is in quotation marks with the full path name), you can highlight all the stuff you don't want on the first file, then use Find and Replace to replace every occurrence of that with nothing. Same with the ending quote (").

It makes a nice clean list of file names.

I had similar problem when using Tomcat6.x and none of the advices I found was helping. At the end I deleted work folder (of Tomcat) and the problem gone.

I know it is illogical but for documentation purpose...

I use PHP to find the URL and match the page name (without the extension of .php, also I can add multiple pages that all have the same word in common like contact, contactform, etc. All will have that class added) and add a class with PHP to change the color, etc. For that you would have to save your pages with file extension .php.

Here is a demo. Change your links and pages as required. The CSS class for all the links is .tab and for the active link there is also another class of .currentpage (as is the PHP function) so that is where you will overwrite your CSS rules. You could name them whatever you like.

<?php # Using REQUEST_URI
    $currentpage = $_SERVER['REQUEST_URI'];?>
    <div class="nav">
        <div class="tab
             <?php
                 if(preg_match("/index/i", $currentpage)||($currentpage=="/"))
                     echo " currentpage";
             ?>"><a href="index.php">Home</a>
         </div>
         <div class="tab
             <?php
                 if(preg_match("/services/i", $currentpage))
                     echo " currentpage";
             ?>"><a href="services.php">Services</a>
         </div>
         <div class="tab
             <?php
                 if(preg_match("/about/i", $currentpage))
                     echo " currentpage";
             ?>"><a href="about.php">About</a>
         </div>
         <div class="tab
             <?php
                 if(preg_match("/contact/i", $currentpage))
                     echo " currentpage";
             ?>"><a href="contact.php">Contact</a>

Another solution to merge more than two arrays

var a = [1, 2],
    b = [3, 4, 5],
    c = [6, 7];

// Merge the contents of multiple arrays together into the first array
var mergeArrays = function() {
 var i, len = arguments.length;
 if (len > 1) {
  for (i = 1; i < len; i++) {
    arguments[0].push.apply(arguments[0], arguments[i]);
  }
 }
};

Then call and print as:

mergeArrays(a, b, c);
console.log(a)

Output will be: Array [1, 2, 3, 4, 5, 6, 7]

Adding this to my connection string worked for me:

Trusted_Connection=true

As others have pointed out, using a fixed-exponent epsilon (such as 0.0000001) will be useless for values away from the epsilon value. For example, if your two values are 10000.000977 and 10000, then there are NO 32-bit floating-point values between these two numbers -- 10000 and 10000.000977 are as close as you can possibly get without being bit-for-bit identical. Here, an epsilon of less than 0.0009 is meaningless; you might as well use the straight equality operator.

Likewise, as the two values approach epsilon in size, the relative error grows to 100%.

Thus, trying to mix a fixed point number such as 0.00001 with floating-point values (where the exponent is arbitrary) is a pointless exercise. This will only ever work if you can be assured that the operand values lie within a narrow domain (that is, close to some specific exponent), and if you properly select an epsilon value for that specific test. If you pull a number out of the air ("Hey! 0.00001 is small, so that must be good!"), you're doomed to numerical errors. I've spent plenty of time debugging bad numerical code where some poor schmuck tosses in random epsilon values to make yet another test case work.

If you do numerical programming of any kind and believe you need to reach for fixed-point epsilons, READ BRUCE'S ARTICLE ON COMPARING FLOATING-POINT NUMBERS.

Comparing Floating Point Numbers

GNU awk 4.1

awk -niord '$0=chr("0x"RT)' RS=.. ORS=

Note that if you echo to this it will produce an extra null byte

$ echo 595a | awk -niord '$0=chr("0x"RT)' RS=.. ORS= | od -tx1c
0000000  59  5a  00
          Y   Z  \0

Instead use printf

$ printf 595a | awk -niord '$0=chr("0x"RT)' RS=.. ORS= | od -tx1c
0000000  59  5a
          Y   Z

Also note that GNU awk produces UTF-8 by default

$ printf a1 | awk -niord '$0=chr("0x"RT)' RS=.. ORS= | od -tx1
0000000 c2 a1

If you are dealing with characters outside of ASCII, and you are going to be Base64 encoding the resultant string, you can disable UTF-8 with -b

echo 5a | sha256sum | awk -bniord 'RT~/\w/,$0=chr("0x"RT)' RS=.. ORS=

You need to use the LAST_INSERT_ID() function with transaction:

START TRANSACTION;
  INSERT INTO dog (name, created_by, updated_by) VALUES ('name', 'migration', 'migration');
  SELECT LAST_INSERT_ID();
COMMIT;

http://dev.mysql.com/doc/refman/5.0/en/information-functions.html#function_last-insert-id

This function will be return last inserted primary key in table.

Adding the padding is rather... fiddly. Here's the function I wrote with the help of the comments in this thread as well as the wiki page for base64 (it's surprisingly helpful) https://en.wikipedia.org/wiki/Base64#Padding.

import logging
import base64
def base64_decode(s):
    """Add missing padding to string and return the decoded base64 string."""
    log = logging.getLogger()
    s = str(s).strip()
    try:
        return base64.b64decode(s)
    except TypeError:
        padding = len(s) % 4
        if padding == 1:
            log.error("Invalid base64 string: {}".format(s))
            return ''
        elif padding == 2:
            s += b'=='
        elif padding == 3:
            s += b'='
        return base64.b64decode(s)

display: block; creates a block-level element, whereas display: inline; creates an inline-level element. It's a bit difficult to explain the difference if you're not familiar with the css box model, but suffice to say that block level elements break up the flow of a document, whereas inline elements do not.

Some examples of block level elements include: div, h1, p, and hr HTML tags.

Some examples of inline level elements include: a, span, strong, em, b, and i HTML tags.

Personally, I like to think of inline elements as typographical elements. This isn't entirely or technically correct, but for the most part inline elements do behave a lot like text.

You can read a more through article on the topic here. Seeing as several other people in this thread have quoted it, it may be worth a read.

I've made a small snippet you can use:

from django.conf import settings
from django.db import connection


def sql_echo(method, *args, **kwargs):
    settings.DEBUG = True
    result = method(*args, **kwargs)
    for query in connection.queries:
        print(query)
    return result


# HOW TO USE EXAMPLE:
# 
# result = sql_echo(my_method, 'whatever', show=True)

It takes as parameters function (contains sql queryies) to inspect and args, kwargs needed to call that function. As the result it returns what function returns and prints SQL queries in a console.

Try to change #include <gl/glut.h> to #include "gl/glut.h" in Visual Studio 2013.

Best way of doing it

Below code is to copy the visible data in DBExtract sheet, and paste it into duplicateRecords sheet, with only filtered values. Range selected by me is the maximum range that can be occupied by my data. You can change it as per your need.

  Sub selectVisibleRange()

    Dim DbExtract, DuplicateRecords As Worksheet
    Set DbExtract = ThisWorkbook.Sheets("Export Worksheet")
    Set DuplicateRecords = ThisWorkbook.Sheets("DuplicateRecords")

    DbExtract.Range("A1:BF9999").SpecialCells(xlCellTypeVisible).Copy
    DuplicateRecords.Cells(1, 1).PasteSpecial

I have run through this. My case was more involved. The project was packaged fine from maven command line.

Couple of things I made. 1. One class has many imports that confused eclipse. Cleaning them fixed part of the problem 2. One case was about a Setter, pressing F3 navigating to that Setter although eclipse complained it is not there. So I simply retyped it and it worked fine (even for all other Setters)

I am still struggling with Implicit super constructor Item() is undefined for default constructor. Must define an explicit constructor"

good luck; :D

To get exact name of control, use:

    string controlName = Page.FindControl(Page.Request.Params["__EVENTTARGET"]).ID;

Something like this lets you test your procedure on almost any client:

DECLARE 
  v_cur SYS_REFCURSOR;
  v_a   VARCHAR2(10);
  v_b   VARCHAR2(10);
BEGIN
  your_proc(v_cur);

  LOOP
    FETCH v_cur INTO v_a, v_b;
    EXIT WHEN v_cur%NOTFOUND;
    dbms_output.put_line(v_a || ' ' || v_b);
  END LOOP;
  CLOSE v_cur;
END;

Basically, your test harness needs to support the definition of a SYS_REFCURSOR variable and the ability to call your procedure while passing in the variable you defined, then loop through the cursor result set. PL/SQL does all that, and anonymous blocks are easy to set up and maintain, fairly adaptable, and quite readable to anyone who works with PL/SQL.

Another, albeit similar way would be to build a named procedure that does the same thing, and assuming the client has a debugger (like SQL Developer, PL/SQL Developer, TOAD, etc.) you could then step through the execution.

I solved it this way, I opened the .sql file in a Notepad and clicked CTRL + H to find and replace the string "utf8mb4_0900_ai_ci" and replaced it with "utf8mb4_general_ci".

I got this error when I was playing around while reading progit. I made a local repository, then fetched it in another repo on the same file system, made an edit and tried to push. After reading NowhereMan's answer, a quick fix was to go to the "remote" directory and temporarily checkout another commit, push from the directory I made changes in, then go back and put the head back on master.

After doing that don't forget to change your href in, <a href="{the chosen redirected name}"> home</a>

Example:

.htaccess file

RewriteEngine On

RewriteRule ^about/$ /about.php

PHP file:

<a href="about/"> about</a>

is it possible to export without looping through all records

For a range in Excel with a large number of rows you may see some performance improvement if you create an Access.Application object in Excel and then use it to import the Excel data into Access. The code below is in a VBA module in the same Excel document that contains the following test data

Option Explicit

Sub AccImport()
    Dim acc As New Access.Application
    acc.OpenCurrentDatabase "C:\Users\Public\Database1.accdb"
    acc.DoCmd.TransferSpreadsheet _
            TransferType:=acImport, _
            SpreadSheetType:=acSpreadsheetTypeExcel12Xml, _
            TableName:="tblExcelImport", _
            Filename:=Application.ActiveWorkbook.FullName, _
            HasFieldNames:=True, _
            Range:="Folio_Data_original$A1:B10"
    acc.CloseCurrentDatabase
    acc.Quit
    Set acc = Nothing
End Sub

First you need to get rid of all newline characters in all your text nodes. Then you can use an identity transform to output your DOM tree. Look at the javadoc for TransformerFactory#newTransformer().

You can use the QMessage object to create a Message Box then add buttons :

QMessageBox msgBox;
msgBox.setWindowTitle("title");
msgBox.setText("Question");
msgBox.setStandardButtons(QMessageBox::Yes);
msgBox.addButton(QMessageBox::No);
msgBox.setDefaultButton(QMessageBox::No);
if(msgBox.exec() == QMessageBox::Yes){
  // do something
}else {
  // do something else
}

Does an implicit conversion occur between Task<> and int?

Nope. This is just part of how async/await works.

Any method declared as async has to have a return type of:

• void (avoid if possible)
• Task (no result beyond notification of completion/failure)
• Task<T> (for a logical result of type T in an async manner)

The compiler does all the appropriate wrapping. The point is that you're asynchronously returning urlContents.Length - you can't make the method just return int, as the actual method will return when it hits the first await expression which hasn't already completed. So instead, it returns a Task<int> which will complete when the async method itself completes.

Note that await does the opposite - it unwraps a Task<T> to a T value, which is how this line works:

string urlContents = await getStringTask;

... but of course it unwraps it asynchronously, whereas just using Result would block until the task had completed. (await can unwrap other types which implement the awaitable pattern, but Task<T> is the one you're likely to use most often.)

This dual wrapping/unwrapping is what allows async to be so composable. For example, I could write another async method which calls yours and doubles the result:

public async Task<int> AccessTheWebAndDoubleAsync()
{
    var task = AccessTheWebAsync();
    int result = await task;
    return result * 2;
}

(Or simply return await AccessTheWebAsync() * 2; of course.)

View model is same as your datamodel but you can add 2 or more data model classes in it. According to that you have to change your controller to take 2 models at once

Internet Explorer versions before IE9 do not support media queries.

If you are looking for a way of degrading the design for IE8 users, you may find IE's conditional commenting helpful. Using this, you can specify an IE 8/7/6 specific style sheet which over writes the previous rules.

For example:

<link rel="stylesheet" type="text/css" media="all" href="style.css"/>
<!--[if lt IE 9]>
<link rel="stylesheet" type="text/css" media="all" href="style-ie.css"/>
<![endif]-->

This won't allow for a responsive design in IE8, but could be a simpler and more accessible solution than using a JS plugin.

If you have ########, it can help you:

=((A1/1000+1*3600)/86400+25569)

+1*3600 is GTM+1

So, the idea is to convert character numbers (in single quotes, e.g. '8') to integer expression. For instance char c = '8'; int i = c - '0' //would yield integer 8; And sum up all the converted numbers by the principle that 908=9*100+0*10+8, which is done in a loop.

char t[5] = {'-', '9', '0', '8', '\0'}; //Should be terminated properly.

int s = 1;
int i = -1;
int res = 0;

if (c[0] == '-') {
  s = -1;
  i = 0;
}

while (c[++i] != '\0') { //iterate until the array end

As an Anaconda user, I wanted to find one or two appropriate commands to solve the problem. Fortunately, this answer helped. For conda 4.5.11 (use conda -V to check Anaconda version) I have performed next steps:

# Python version does not matter, most likely, check yourself
conda create -n myenv python=3.6     
conda activate myenv
conda install -c menpo opencv

That will install OpenCV 2.4.11. Anaconda's another command conda install -c menpo opencv3 will install OpenCV3, but Python has to be downgraded to 2.7. To install OpenCV3 with Python3 use next (due to the first link):

conda create -n myenv python  
pip install opencv-python==3.4.2.16
pip install opencv-contrib-python==3.4.2.16

Check the SIFT:

conda activate myenv
python
>>> cv2.xfeatures2d.SIFT_create()
<xfeatures2d_SIFT 000002A3478655B0>

the easiest and safest way is to use something like this:

var waitForJQuery = setInterval(function () {
    if (typeof $ != 'undefined') {

        // place your code here.

        clearInterval(waitForJQuery);
    }
}, 10);

git commit is to commit the files that is staged in the local repo. git push is to fast-forward merge the master branch of local side with the remote master branch. But the merge won't always success. If rejection appears, you have to pull so that you can make a successful git push.

Another much simpler possibility is that one of your property names is wrong (probably one you just changed in the class). This is what it was for me in RazorPages .NET Core 3.

gettimeofday() will probably do what you want.

If you're on Intel hardware, here's how to read the CPU real-time instruction counter. It will tell you the number of CPU cycles executed since the processor was booted. This is probably the finest-grained, lowest overhead counter you can get for performance measurement.

Note that this is the number of CPU cycles. On linux you can get the CPU speed from /proc/cpuinfo and divide to get the number of seconds. Converting this to a double is quite handy.

When I run this on my box, I get

11867927879484732
11867927879692217
it took this long to call printf: 207485

Here's the Intel developer's guide that gives tons of detail.

#include <stdio.h>
#include <stdint.h>

inline uint64_t rdtsc() {
    uint32_t lo, hi;
    __asm__ __volatile__ (
      "xorl %%eax, %%eax\n"
      "cpuid\n"
      "rdtsc\n"
      : "=a" (lo), "=d" (hi)
      :
      : "%ebx", "%ecx");
    return (uint64_t)hi << 32 | lo;
}

main()
{
    unsigned long long x;
    unsigned long long y;
    x = rdtsc();
    printf("%lld\n",x);
    y = rdtsc();
    printf("%lld\n",y);
    printf("it took this long to call printf: %lld\n",y-x);
}

You don't actually need a form to do this with Prototype. Just use Object.toQueryString function:

Object.toQueryString({ action: 'ship', order_id: 123, fees: ['f1', 'f2'], 'label': 'a demo' })

// -> 'action=ship&order_id=123&fees=f1&fees=f2&label=a%20demo'

I have just installed mongodb 3.4 with homebrew.(brew install mongodb) It looks for /data/db by default.

This worked for me. Others might find it useful.

// date = 2020-08-31T00:00:00Z I'm located in Denmark (timezone is +2 hours)

moment.utc(moment(date).utc()).format() // returns 2020-08-30T22:00:00Z

Since this seems to be the de facto SO question for left outer joins using the method (extension) syntax, I thought I would add an alternative to the currently selected answer that (in my experience at least) has been more commonly what I'm after

// Option 1: Expecting either 0 or 1 matches from the "Right"
// table (Bars in this case):
var qry = Foos.GroupJoin(
          Bars,
          foo => foo.Foo_Id,
          bar => bar.Foo_Id,
          (f,bs) => new { Foo = f, Bar = bs.SingleOrDefault() });

// Option 2: Expecting either 0 or more matches from the "Right" table
// (courtesy of currently selected answer):
var qry = Foos.GroupJoin(
                  Bars, 
                  foo => foo.Foo_Id,
                  bar => bar.Foo_Id,
                  (f,bs) => new { Foo = f, Bars = bs })
              .SelectMany(
                  fooBars => fooBars.Bars.DefaultIfEmpty(),
                  (x,y) => new { Foo = x.Foo, Bar = y });

To display the difference using a simple data set (assuming we're joining on the values themselves):

List<int> tableA = new List<int> { 1, 2, 3 };
List<int?> tableB = new List<int?> { 3, 4, 5 };

// Result using both Option 1 and 2. Option 1 would be a better choice
// if we didn't expect multiple matches in tableB.
{ A = 1, B = null }
{ A = 2, B = null }
{ A = 3, B = 3    }

List<int> tableA = new List<int> { 1, 2, 3 };
List<int?> tableB = new List<int?> { 3, 3, 4 };

// Result using Option 1 would be that an exception gets thrown on
// SingleOrDefault(), but if we use FirstOrDefault() instead to illustrate:
{ A = 1, B = null }
{ A = 2, B = null }
{ A = 3, B = 3    } // Misleading, we had multiple matches.
                    // Which 3 should get selected (not arbitrarily the first)?.

// Result using Option 2:
{ A = 1, B = null }
{ A = 2, B = null }
{ A = 3, B = 3    }
{ A = 3, B = 3    }    

Option 2 is true to the typical left outer join definition, but as I mentioned earlier is often unnecessarily complex depending on the data set.

Typographically, the correct glyph to use in sentence punctuation is the quote mark, both single (including for apostrophes) and double quotes. The straight-looking mark that we often see on the web is called a prime, which also comes in single and double varieties and has limited uses, mostly for measurements.

This article explains how to use them correctly.

.class {
    background-color:none;
}

This is not a valid property. W3C validator will display following error:

Value Error : background-color none is not a background-color value : none

transparent may have been selected as better term instead of 0 or none values during the development of specification of CSS.

There are 3 basic commands to compare files in unix:

1. cmp : This command is used to compare two files byte by byte and as any mismatch occurs,it echoes it on the screen.if no mismatch occurs i gives no response. syntax:$cmp file1 file2.

2. comm : This command is used to find out the records available in one but not in another

3. diff

Python 3.9 adds the zoneinfo module so now only the standard library is needed!

from zoneinfo import ZoneInfo
from datetime import datetime
unaware = datetime(2020, 10, 31, 12)

Attach a timezone:

>>> unaware.replace(tzinfo=ZoneInfo('Asia/Tokyo'))
datetime.datetime(2020, 10, 31, 12, 0, tzinfo=zoneinfo.ZoneInfo(key='Asia/Tokyo'))
>>> str(_)
'2020-10-31 12:00:00+09:00'

Attach the system's local timezone:

>>> unaware.replace(tzinfo=ZoneInfo('localtime'))
datetime.datetime(2020, 10, 31, 12, 0, tzinfo=zoneinfo.ZoneInfo(key='localtime'))
>>> str(_)
'2020-10-31 12:00:00+01:00'

Subsequently it is properly converted to other timezones:

>>> unaware.replace(tzinfo=ZoneInfo('localtime')).astimezone(ZoneInfo('Asia/Tokyo'))
datetime.datetime(2020, 10, 31, 20, 0, tzinfo=backports.zoneinfo.ZoneInfo(key='Asia/Tokyo'))
>>> str(_)
'2020-10-31 20:00:00+09:00'

Wikipedia list of available time zones

Windows has no system time zone database, so here an extra package is needed:

pip install tzdata  

There is a backport to allow use of zoneinfo in Python 3.6 to 3.8:

pip install backports.zoneinfo

Then:

from backports.zoneinfo import ZoneInfo

It might be a little tricky, but you can make use of Intl.DateTimeFormat.

The snippet bellow can help you convert any date with any timezone to its begining/end time.

const beginingOfDay = (options = {}) => {
  const { date = new Date(), timeZone } = options;
  const parts = Intl.DateTimeFormat("en-US", {
    timeZone,
    hourCycle: "h23",
    hour: "numeric",
    minute: "numeric",
    second: "numeric",
  }).formatToParts(date);
  const hour = parseInt(parts.find((i) => i.type === "hour").value);
  const minute = parseInt(parts.find((i) => i.type === "minute").value);
  const second = parseInt(parts.find((i) => i.type === "second").value);
  return new Date(
    1000 *
      Math.floor(
        (date - hour * 3600000 - minute * 60000 - second * 1000) / 1000
      )
  );
};

const endOfDay = (...args) =>
  new Date(beginingOfDay(...args).getTime() + 86399999);

const beginingOfYear = () => {};

console.log(beginingOfDay({ timeZone: "GMT" }));
console.log(endOfDay({ timeZone: "GMT" }));
console.log(beginingOfDay({ timeZone: "Asia/Tokyo" }));
console.log(endOfDay({ timeZone: "Asia/Tokyo" }));

Here is another method to add days on date using dateutil's relativedelta.

from datetime import datetime
from dateutil.relativedelta import relativedelta

print 'Today: ',datetime.now().strftime('%d/%m/%Y %H:%M:%S') 
date_after_month = datetime.now()+ relativedelta(day=1)
print 'After a Days:', date_after_month.strftime('%d/%m/%Y %H:%M:%S')

Output:

Today: 25/06/2015 20:41:44

After a Days: 01/06/2015 20:41:44

You declared them, but you didn't initialize them. Initializing them is setting them equal to a value:

int a;        // This is a declaration
a = 0;        // This is an initialization
int b = 1;    // This is a declaration and initialization

You get the error because you haven't initialized the variables, but you increment them (e.g., a++) in the for loop.

Java primitives have default values but as one user commented below

Their default value is zero when declared as class members. Local variables don't have default values

Depends on the consistency of the data - assuming a single space is the separator between what you want to appear in column one vs two:

SELECT SUBSTR(t.column_one, 1, INSTR(t.column_one, ' ')-1) AS col_one,
       SUBSTR(t.column_one, INSTR(t.column_one, ' ')+1) AS col_two
  FROM YOUR_TABLE t

Oracle 10g+ has regex support, allowing more flexibility depending on the situation you need to solve. It also has a regex substring method...

Reference:

• SUBSTR
• INSTR

This isn't significantly different from other answers, but I wanted the array of integers in the end:

    Integer[] indices = new Integer[n];
    Arrays.setAll(indices, i -> i);
    Collections.shuffle(Arrays.asList(indices));
    return Arrays.stream(indices).mapToInt(Integer::intValue).toArray();

When you put the username and password in front of the host, this data is not sent that way to the server. It is instead transformed to a request header depending on the authentication schema used. Most of the time this is going to be Basic Auth which I describe below. A similar (but significantly less often used) authentication scheme is Digest Auth which nowadays provides comparable security features.

With Basic Auth, the HTTP request from the question will look something like this:

GET / HTTP/1.1
Host: example.com
Authorization: Basic Zm9vOnBhc3N3b3Jk

The hash like string you see there is created by the browser like this: base64_encode(username + ":" + password).

To outsiders of the HTTPS transfer, this information is hidden (as everything else on the HTTP level). You should take care of logging on the client and all intermediate servers though. The username will normally be shown in server logs, but the password won't. This is not guaranteed though. When you call that URL on the client with e.g. curl, the username and password will be clearly visible on the process list and might turn up in the bash history file.

When you send passwords in a GET request as e.g. http://example.com/login.php?username=me&password=secure the username and password will always turn up in server logs of your webserver, application server, caches, ... unless you specifically configure your servers to not log it. This only applies to servers being able to read the unencrypted http data, like your application server or any middleboxes such as loadbalancers, CDNs, proxies, etc. though.

Basic auth is standardized and implemented by browsers by showing this little username/password popup you might have seen already. When you put the username/password into an HTML form sent via GET or POST, you have to implement all the login/logout logic yourself (which might be an advantage and allows you to more control over the login/logout flow for the added "cost" of having to implement this securely again). But you should never transfer usernames and passwords by GET parameters. If you have to, use POST instead. The prevents the logging of this data by default.

When implementing an authentication mechanism with a user/password entry form and a subsequent cookie-based session as it is commonly used today, you have to make sure that the password is either transported with POST requests or one of the standardized authentication schemes above only.

Concluding I could say, that transfering data that way over HTTPS is likely safe, as long as you take care that the password does not turn up in unexpected places. But that advice applies to every transfer of any password in any way.

That's no problem.

@Html.Partial("../Controller/View", model)

or

@Html.Partial("~/Views/Controller/View.cshtml", model)

Should do the trick.

If you want to pass through the (other) controller, you can use:

@Html.Action("action", "controller", parameters)

or any of the other overloads

I'm not familiar with resolve, but I've used the others:

Recursive

Recursive is the default for non-fast-forward merges. We're all familiar with that one.

Octopus

I've used octopus when I've had several trees that needed to be merged. You see this in larger projects where many branches have had independent development and it's all ready to come together into a single head.

An octopus branch merges multiple heads in one commit as long as it can do it cleanly.

For illustration, imagine you have a project that has a master, and then three branches to merge in (call them a, b, and c).

A series of recursive merges would look like this (note that the first merge was a fast-forward, as I didn't force recursion):

However, a single octopus merge would look like this:

commit ae632e99ba0ccd0e9e06d09e8647659220d043b9
Merge: f51262e... c9ce629... aa0f25d...

Ours

Ours == I want to pull in another head, but throw away all of the changes that head introduces.

This keeps the history of a branch without any of the effects of the branch.

(Read: It is not even looked at the changes between those branches. The branches are just merged and nothing is done to the files. If you want to merge in the other branch and every time there is the question "our file version or their version" you can use git merge -X ours)

Subtree

Subtree is useful when you want to merge in another project into a subdirectory of your current project. Useful when you have a library you don't want to include as a submodule.

I know the question is quite old, but I got here searching for answers. There is actually a better (and faster) way now of doing this using json_normalize:

import pandas as pd

df2 = pd.json_normalize(df['Pollutant Levels'])

This avoids costly apply functions...

On the much shorter format:

def fibbo(range_, a, b):
    if(range_!=0):
        a, b = b, a+b
        print(a)
        return fibbo(range_-1, a, b)
    return

fibbo(11, 1, 0)

You can just use 7zip (or another similar app) to get the dirs inside the core.zip file that's bundled in the installer. Just use 7zip to browse the exe, you'll see a core.zip file which has all the files that usually go inside "jreX" dir (where X is the major version number). As for setting env variables and the such, you can follow the other answers. If all you want is a portable jre (for example, you can run your jars by using java.exe jarfile or javaw.exe jarfile) then this solution will do. This is very similar to copying the jre dir from one place to another

Click: "Application Development Features"

Check (enable) the features. I checked all but CGI.

StringUtils.equalsAny(CharSequence string, CharSequence... searchStrings)

So in your case, it would be

StringUtils.equalsAny(str, "val1", "val2", "val3");

Simple way in Java

public void resize(String inputImagePath,
            String outputImagePath, int scaledWidth, int scaledHeight)
            throws IOException {
        // reads input image
        File inputFile = new File(inputImagePath);
        BufferedImage inputImage = ImageIO.read(inputFile);
 
        // creates output image
        BufferedImage outputImage = new BufferedImage(scaledWidth,
                scaledHeight, inputImage.getType());
 
        // scales the input image to the output image
        Graphics2D g2d = outputImage.createGraphics();
        g2d.drawImage(inputImage, 0, 0, scaledWidth, scaledHeight, null);
        g2d.dispose();
 
        // extracts extension of output file
        String formatName = outputImagePath.substring(outputImagePath
                .lastIndexOf(".") + 1);
 
        // writes to output file
        ImageIO.write(outputImage, formatName, new File(outputImagePath));
    }

I came here looking for the answer and since no one put the command for the oracle Java 11 but only openjava 11 I figured out how to do it on Ubuntu, the syntax is as following:

sudo add-apt-repository ppa:linuxuprising/java
sudo apt update
sudo apt install oracle-java11-installer

I tried your code and found it wasn't working.

I had to change

if (intent.getAction() == SMS_RECEIVED) {

to

if (intent.getAction().equals(SMS_RECEIVED)) {

Now it's working. It's just an issue with java checking equality.

Using @Jarda's guide you can define this if you need to set the variable the same value for all tests:

@Before
public void setClientMapper() throws NoSuchFieldException, SecurityException{
    FieldSetter.setField(client, client.getClass().getDeclaredField("mapper"), new Mapper());
}

But beware that setting private values to be different should be handled with care. If they are private are for some reason.

Example, I use it, for example, to change the wait time of a sleep in the unit tests. In real examples I want to sleep for 10 seconds but in unit-test I'm satisfied if it's immediate. In integration tests you should test the real value.

As a matter of fact, HTML character entites also work : http://www.w3.org/TR/html4/sgml/entities.html.

It lets you insert special characters like bullets '•' (&bull;), '™' (&trade;), ... the HTML way.

Note that you can also (and probably should) type special characters directly in the form fields if you can enter international characters.

=> one consideration here is whether or not you care about third-party sites that collect data on your app from Google Play : some might simply take it as HTML content, others might insert it in a native application that just understand plain Unicode...

The wording of the error message corresponds to what you get from Google Chrome when you run JSON.parse('<...'). I know you said the server is setting Content-Type:application/json, but I am led to believe the response body is actually HTML.

Feed.js:94 undefined "parsererror" "SyntaxError: Unexpected token < in JSON at position 0"

with the line console.error(this.props.url, status, err.toString()) underlined.

The err was actually thrown within jQuery, and passed to you as a variable err. The reason that line is underlined is simply because that is where you are logging it.

I would suggest that you add to your logging. Looking at the actual xhr (XMLHttpRequest) properties to learn more about the response. Try adding console.warn(xhr.responseText) and you will most likely see the HTML that is being received.

The debate between cssSelector vs XPath would remain as one of the most subjective debate in the Selenium Community. What we already know so far can be summarized as:

• People in favor of cssSelector say that it is more readable and faster (especially when running against Internet Explorer).
• While those in favor of XPath tout it's ability to transverse the page (while cssSelector cannot).
• Traversing the DOM in older browsers like IE8 does not work with cssSelector but is fine with XPath.
• XPath can walk up the DOM (e.g. from child to parent), whereas cssSelector can only traverse down the DOM (e.g. from parent to child)
• However not being able to traverse the DOM with cssSelector in older browsers isn't necessarily a bad thing as it is more of an indicator that your page has poor design and could benefit from some helpful markup.
• Ben Burton mentions you should use cssSelector because that's how applications are built. This makes the tests easier to write, talk about, and have others help maintain.
• Adam Goucher says to adopt a more hybrid approach -- focusing first on IDs, then cssSelector, and leveraging XPath only when you need it (e.g. walking up the DOM) and that XPath will always be more powerful for advanced locators.

Dave Haeffner carried out a test on a page with two HTML data tables, one table is written without helpful attributes (ID and Class), and the other with them. I have analyzed the test procedure and the outcome of this experiment in details in the discussion Why should I ever use cssSelector selectors as opposed to XPath for automated testing?. While this experiment demonstrated that each Locator Strategy is reasonably equivalent across browsers, it didn't adequately paint the whole picture for us. Dave Haeffner in the other discussion Css Vs. X Path, Under a Microscope mentioned, in an an end-to-end test there were a lot of other variables at play Sauce startup, Browser start up, and latency to and from the application under test. The unfortunate takeaway from that experiment could be that one driver may be faster than the other (e.g. IE vs Firefox), when in fact, that's wasn't the case at all. To get a real taste of what the performance difference is between cssSelector and XPath, we needed to dig deeper. We did that by running everything from a local machine while using a performance benchmarking utility. We also focused on a specific Selenium action rather than the entire test run, and run things numerous times. I have analyzed the specific test procedure and the outcome of this experiment in details in the discussion cssSelector vs XPath for selenium. But the tests were still missing one aspect i.e. more browser coverage (e.g., Internet Explorer 9 and 10) and testing against a larger and deeper page.

Dave Haeffner in another discussion Css Vs. X Path, Under a Microscope (Part 2) mentions, in order to make sure the required benchmarks are covered in the best possible way we need to consider an example that demonstrates a large and deep page.

Test SetUp

To demonstrate this detailed example, a Windows XP virtual machine was setup and Ruby (1.9.3) was installed. All the available browsers and their equivalent browser drivers for Selenium was also installed. For benchmarking, Ruby's standard lib benchmark was used.

Results

NOTE: The output is in seconds, and the results are for the total run time of 100 executions.

In Table Form:

In Chart Form:

• Chrome:

• Firefox:

• Internet Explorer 8:

• Internet Explorer 9:

• Internet Explorer 10:

• Opera:

Analyzing the Results

• Chrome and Firefox are clearly tuned for faster cssSelector performance.
• Internet Explorer 8 is a grab bag of cssSelector that won't work, an out of control XPath traversal that takes ~65 seconds, and a 38 second table traversal with no cssSelector result to compare it against.
• In IE 9 and 10, XPath is faster overall. In Safari, it's a toss up, except for a couple of slower traversal runs with XPath. And across almost all browsers, the nested sibling traversal and table cell traversal done with XPath are an expensive operation.
• These shouldn't be that surprising since the locators are brittle and inefficient and we need to avoid them.

Summary

• Overall there are two circumstances where XPath is markedly slower than cssSelector. But they are easily avoidable.
• The performance difference is slightly in favor of css-selectors for non-IE browsers and slightly in favor of xpath for IE browsers.

Trivia

You can perform the bench-marking on your own, using this library where Dave Haeffner wrapped up all the code.

I used the answer from Paul Pladijs since now. I found out, you can do a "normal" merge, conflicts occur, so you do

git checkout --theirs <file>

to resolve the conflict by using the revision from the other branch. If you do this for each file, you have the same behaviour as you would expect from

git merge <branch> -s theirs

Anyway, the effort is more than it would be with the merge-strategy! (This was tested with git version 1.8.0)

Neil's answer is by far the best one. However things get messy really fast. My suggestion would be to use variables to store elements and append them to the DOM hierarchy.

HTML

<table id="tableID">
    <tbody>
    </tbody>
</table>

JAVASCRIPT

// Reference to the table body
var body = $("#tableID").find('tbody');

// Create a new row element
var row = $('<tr>');

// Create a new column element
var column = $('<td>');

// Create a new image element
var image = $('<img>');
image.attr('src', 'img.png');
image.text('Image cell');

// Append the image to the column element
column.append(image);
// Append the column to the row element
row.append(column);
// Append the row to the table body
body.append(row);

This message comes when the keyboard type is set to numberPad or DecimalPad. But the code works just fine. Looks like its a bug with the new Xcode.

While there are JS implementations of the MD5 algorithm, older browsers are generally unable to read files from the local filesystem.

I wrote that in 2009. So what about new browsers?

With a browser that supports the FileAPI, you *can * read the contents of a file - the user has to have selected it, either with an <input> element or drag-and-drop. As of Jan 2013, here's how the major browsers stack up:

• FF 3.6 supports FileReader, FF4 supports even more file based functionality
• Chrome has supported the FileAPI since version 7.0.517.41
• Internet Explorer 10 has partial FileAPI support
• Opera 11.10 has partial support for FileAPI
• Safari - I couldn't find a good official source for this, but this site suggests partial support from 5.1, full support for 6.0. Another article reports some inconsistencies with the older Safari versions

On SQL Server 2008+ it is possible to use Table Valued Parameters to pass in a table variable to a dynamic SQL statement as long as you don't need to update the values in the table itself.

So from the code you posted you could use this approach for @TSku but not for @RelPro

Example syntax below.

CREATE TYPE MyTable AS TABLE 
( 
Foo int,
Bar int
);
GO


DECLARE @T AS MyTable;

INSERT INTO @T VALUES (1,2), (2,3)

SELECT *,
        sys.fn_PhysLocFormatter(%%physloc%%) AS [physloc]
FROM @T

EXEC sp_executesql
  N'SELECT *,
        sys.fn_PhysLocFormatter(%%physloc%%) AS [physloc]
    FROM @T',
  N'@T MyTable READONLY',
  @T=@T 

The physloc column is included just to demonstrate that the table variable referenced in the child scope is definitely the same one as the outer scope rather than a copy.

Escape the apostrophe (i.e. double-up the single quote character) in your SQL:

INSERT INTO Person
    (First, Last)
VALUES
    ('Joe', 'O''Brien')
              /\
          right here  

The same applies to SELECT queries:

SELECT First, Last FROM Person WHERE Last = 'O''Brien'

The apostrophe, or single quote, is a special character in SQL that specifies the beginning and end of string data. This means that to use it as part of your literal string data you need to escape the special character. With a single quote this is typically accomplished by doubling your quote. (Two single quote characters, not double-quote instead of a single quote.)

Note: You should only ever worry about this issue when you manually edit data via a raw SQL interface since writing queries outside of development and testing should be a rare occurrence. In code there are techniques and frameworks (depending on your stack) that take care of escaping special characters, SQL injection, etc.

The code below creates a Documents directory and then a sub-directory for the application and saved the files to it.

public class loadDataTooDisk extends AsyncTask<String, Integer, String> {
    String sdCardFileTxt;
    @Override
    protected String doInBackground(String... params)
    {

        //check to see if external storage is avalibel
        checkState();
        if(canW == canR == true)
        {
            //get the path to sdcard 
            File pathToExternalStorage = Environment.getExternalStorageDirectory();
            //to this path add a new directory path and create new App dir (InstroList) in /documents Dir
            File appDirectory = new File(pathToExternalStorage.getAbsolutePath()  + "/documents/InstroList");
            // have the object build the directory structure, if needed.
            appDirectory.mkdirs();
            //test to see if it is a Text file
            if ( myNewFileName.endsWith(".txt") )
            {

                //Create a File for the output file data
                File saveFilePath = new File (appDirectory, myNewFileName);
                //Adds the textbox data to the file
                try{
                    String newline = "\r\n";
                    FileOutputStream fos = new FileOutputStream (saveFilePath);
                    OutputStreamWriter OutDataWriter  = new OutputStreamWriter(fos);

                    OutDataWriter.write(equipNo.getText() + newline);
                    // OutDataWriter.append(equipNo.getText() + newline);
                    OutDataWriter.append(equip_Type.getText() + newline);
                    OutDataWriter.append(equip_Make.getText()+ newline);
                    OutDataWriter.append(equipModel_No.getText()+ newline);
                    OutDataWriter.append(equip_Password.getText()+ newline);
                    OutDataWriter.append(equipWeb_Site.getText()+ newline);
                    //OutDataWriter.append(equipNotes.getText());
                    OutDataWriter.close();

                    fos.flush();
                    fos.close();

                }catch(Exception e){
                    e.printStackTrace();
                }
            }
        }
        return null;
    }
}

This one builds the file name

   private String BuildNewFileName()
    { // creates a new filr name
        Time today = new Time(Time.getCurrentTimezone());
        today.setToNow();

        StringBuilder sb = new StringBuilder();

        sb.append(today.year + "");                // Year)
        sb.append("_");
        sb.append(today.monthDay + "");          // Day of the month (1-31)
        sb.append("_");
        sb.append(today.month + "");              // Month (0-11))
        sb.append("_");
        sb.append(today.format("%k:%M:%S"));      // Current time
        sb.append(".txt");                      //Completed file name

        myNewFileName = sb.toString();
        //Replace (:) with (_)
        myNewFileName = myNewFileName.replaceAll(":", "_");

        return myNewFileName;
    }

Hope this helps! It took me a long time to get it working.

the only way to do this is to replace document.write with your own function which will append elements to the bottom of your page. It is pretty straight forward with jQuery:

document.write = function(htmlToWrite) {
  $(htmlToWrite).appendTo('body');
}

If you have html coming to document.write in chunks like the question example you'll need to buffer the htmlToWrite segments. Maybe something like this:

document.write = (function() {
  var buffer = "";
  var timer;
  return function(htmlPieceToWrite) {
    buffer += htmlPieceToWrite;
    clearTimeout(timer);
    timer = setTimeout(function() {
      $(buffer).appendTo('body');
      buffer = "";
    }, 0)
  }
})()

First thing to do is run this:

SHOW GRANTS;

You will quickly see you were assigned the anonymous user to authenticate into mysql.

Instead of logging into mysql with

mysql

login like this:

mysql -uroot

By default, root@localhost has all rights and no password.

If you cannot login as root without a password, do the following:

Step 01) Add the two options in the mysqld section of my.ini:

[mysqld]
skip-grant-tables
skip-networking

Step 02) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 03) Connect to mysql

mysql

Step 04) Create a password from root@localhost

UPDATE mysql.user SET password=password('whateverpasswordyoulike')
WHERE user='root' AND host='localhost';
exit

Step 05) Restart mysql

net stop mysql
<wait 10 seconds>
net start mysql

Step 06) Login as root with password

mysql -u root -p

You should be good from there.

CAVEAT: Please remove anonymous users !!!

h1 {
  font-weight: bold;
  color: #fff;
  font-size: 32px;
}

h2 {
  font-weight: bold;
  color: #fff;
  font-size: 24px;
}

Note that after color you can use a word (e.g. white), a hex code (e.g. #fff) or RGB (e.g. rgb(255,255,255)) or RGBA (e.g. rgba(255,255,255,0.3)).

I faced similar problem on windows server 2012 STD 64 bit , my problem is resolved after updating windows with all available windows updates.

The difference between memcpy and memmove is that

1. in memmove, the source memory of specified size is copied into buffer and then moved to destination. So if the memory is overlapping, there are no side effects.

2. in case of memcpy(), there is no extra buffer taken for source memory. The copying is done directly on the memory so that when there is memory overlap, we get unexpected results.

These can be observed by the following code:

//include string.h, stdio.h, stdlib.h
int main(){
  char a[]="hare rama hare rama";

  char b[]="hare rama hare rama";

  memmove(a+5,a,20);
  puts(a);

  memcpy(b+5,b,20);
  puts(b);
}

Output is:

hare hare rama hare rama
hare hare hare hare hare hare rama hare rama

Sometimes in similar situations (I don't think it is your problem because your case is very simple) it's worth to check kotlin file package.

If you have Kotlin file within the same package and put there some classes and missed the package declaration it looks inside the IntelliJ that you have classes in the same package but without definition of package the IntelliJ shows you:

Error:(5, 5) Kotlin: Unresolved reference: ...

Additionally to overflow:hidden, use

white-space:nowrap;

Strict aliasing doesn't refer only to pointers, it affects references as well, I wrote a paper about it for the boost developer wiki and it was so well received that I turned it into a page on my consulting web site. It explains completely what it is, why it confuses people so much and what to do about it. Strict Aliasing White Paper. In particular it explains why unions are risky behavior for C++, and why using memcpy is the only fix portable across both C and C++. Hope this is helpful.

For you who, like me, already did setup you ssh-keys but still get the errors:

Make sure you did setup a push remote. It worked for me when I got both the Cannot get remote repository refs-problems ("... Passphrase for..." and "Auth fail" in the "Push..." dialog).

Provided that you already:

1. Setup your SSH keys with Github (Window > Preferences > General > Network Connections > SSH2)

2. Setup your local repository (you can follow this guide for that)

3. Created a Github repository (same guide)

... here's how you do it:

• Go to the Git Repositories view (Window > Show View > Other > Git Repositories)
• Expand your Repository and right click Remotes --> "Create Remote"
• "Remote Name": origin, "Configure push": checked --> click "OK"
• Click the "Change..." button
• Paste your git URI and select protocol ssh --> click "Finish"
• Now, click "Save and Push" and NOW you should get a password prompt --> enter the public key passphrase here (provided that you DID (and you should) setup a passphrase to your public key) --> click "OK"
• Now you should get a confirmation window saying "Pushed to YourRepository - origin" --> click "OK"
• Push to upstream, but this time use "Configured remote repository" as your Destination Git repository
• Go get yourself a well earned cup of coffee!

With the following code you can load the controller classes and execute the methods.

This code was written for codeigniter 2.1

First add a new file MY_Loader.php in your application/core directory. Add the following code to your newly created MY_Loader.php file:

                load_class('Controller', 'core');
            }

            require_once($mod_path.'controllers/'.$path.$controller.'.php');

            $controller = ucfirst($controller);

            $CI->$name = new $controller();

            $this->_my_controllers[] = $name;
            return;
        }

        // couldn't find the controller
        show_error('Unable to locate the controller you have specified: '.$controller);
    }

}

Now you can load all the controllers in your application/controllers directory. for example:

load the controller class Invoice and execute the function test()

$this->load->controller('invoice','invoice_controller');

$this->invoice_controller->test();

or when the class is within a dir

$this->load->controller('/dir/invoice','invoice_controller');

$this->invoice_controller->test();

It just works the same like loading a model

If when you set disabled="disabled" immediately after the user clicks the button, and the form doesn't submit because of that, you could try two things:

//First choice [given myForm = your form]:
myInputButton.disabled = "disabled";
myForm.submit()

//Second choice:
setTimeout(disableFunction, 1);  
//so the form will submit and then almost instantly, the button will be disabled  

Although I honestly bet there will be a better way to do this, than that.

Redirection/Piping the output of the file to wc -l should suffice, like the following:

cat /etc/fstab | wc -l

which then would provide the no. of lines only.

Since I have struggled and found a slightly different answer here it is:

I recently switched the local (intranet) server at my new workplace. Installed a LAMP; Debian, Apache, MySql, PHP. The users at work connect the server by using the hostname, lets call it "intaserv". I set up everything, got it working but could not connect my MySql remotely whatever I did.

I found my answer after endless tries though. You can only have one bind-address and it cannot be hostname, in my case "intranet".

It has to be an IP-address in eg. "bind-address=192.168.0.50".

I had this problem during migration to Spring Boot. I've found a advice to remove dependencies and it helped. So, I removed dependency for jsp-api Project had. Also, servlet-api dependency has to be removed as well.

compileOnly group: 'javax.servlet.jsp', name: 'jsp-api', version: '2.2' 

The or and and python statements require truth-values. For pandas these are considered ambiguous so you should use "bitwise" | (or) or & (and) operations:

result = result[(result['var']>0.25) | (result['var']<-0.25)]

These are overloaded for these kind of datastructures to yield the element-wise or (or and).

Just to add some more explanation to this statement:

The exception is thrown when you want to get the bool of a pandas.Series:

>>> import pandas as pd
>>> x = pd.Series([1])
>>> bool(x)
ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().

What you hit was a place where the operator implicitly converted the operands to bool (you used or but it also happens for and, if and while):

>>> x or x
ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().
>>> x and x
ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().
>>> if x:
...     print('fun')
ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().
>>> while x:
...     print('fun')
ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().

Besides these 4 statements there are several python functions that hide some bool calls (like any, all, filter, ...) these are normally not problematic with pandas.Series but for completeness I wanted to mention these.

In your case the exception isn't really helpful, because it doesn't mention the right alternatives. For and and or you can use (if you want element-wise comparisons):

• numpy.logical_or:

  >>> import numpy as np
  >>> np.logical_or(x, y)
  

  or simply the | operator:

  >>> x | y
  

• numpy.logical_and:

  >>> np.logical_and(x, y)
  

  or simply the & operator:

  >>> x & y
  

If you're using the operators then make sure you set your parenthesis correctly because of the operator precedence.

There are several logical numpy functions which should work on pandas.Series.

The alternatives mentioned in the Exception are more suited if you encountered it when doing if or while. I'll shortly explain each of these:

• If you want to check if your Series is empty:

  >>> x = pd.Series([])
  >>> x.empty
  True
  >>> x = pd.Series([1])
  >>> x.empty
  False
  

  Python normally interprets the length of containers (like list, tuple, ...) as truth-value if it has no explicit boolean interpretation. So if you want the python-like check, you could do: if x.size or if not x.empty instead of if x.

• If your Series contains one and only one boolean value:

  >>> x = pd.Series([100])
  >>> (x > 50).bool()
  True
  >>> (x < 50).bool()
  False
  

• If you want to check the first and only item of your Series (like .bool() but works even for not boolean contents):

  >>> x = pd.Series([100])
  >>> x.item()
  100
  

• If you want to check if all or any item is not-zero, not-empty or not-False:

  >>> x = pd.Series([0, 1, 2])
  >>> x.all()   # because one element is zero
  False
  >>> x.any()   # because one (or more) elements are non-zero
  True
  

You use RAISE_APPLICATION_ERROR in order to create an Oracle style exception/error that is specific to your code/needs. Good use of these help to produce code that is clearer, more maintainable, and easier to debug.

For example, if I have an application calling a stored procedure that adds a user and that user already exists, you'll usually get back an error like:

ORA-00001: unique constraint (USERS.PK_USER_KEY) violated

Obviously this error and associated message are not unique to the task you were trying to do. Creating your own Oracle application errors allow you to be clearer on the intent of the action and the cause of the issue.

raise_application_error(-20101, 'User ' || in_user || ' already exists!');

Now your application code can write an exception handler in order to process this specific error condition. Think of it as a way to make Oracle communicate error conditions that your application expects in a "language" (for lack of a better term) that you have defined and is more meaningful to your application's problem domain.

Note that user defined errors must be in the range between -20000 and -20999.

The following link provides lots of good information on this topic and Oracle exceptions in general.

From @Johan La Rooy's solution, sorting the images using sorted(glob.glob('*.png')) does not work for me, the output list is still not ordered by their names.

However, the sorted(glob.glob('*.png'), key=os.path.getmtime) works perfectly.

I am a bit confused how can sorting by their names does not work here.

Thank @Martin Thoma for posting this great question and @Johan La Rooy for the helpful solutions.

Copy code using clone and appendTo function :

Here is also working example jsfiddle

<!DOCTYPE html>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
</head>
<body>
<div id="copy"><a href="http://brightwaay.com">Here</a> </div>
<br/>
<div id="copied"></div>
<script type="text/javascript">
    $(function(){
        $('#copy').clone().appendTo('#copied');
    });
</script>
</body>
</html>

One thing you might want to consider besides the other issues mentioned is that isEmpty() was introduced in 1.6, so if you use it you won't be able to run the code on Java 1.5 or below.

It would probably be easier to just fake it by using a div. Just make sure you set the height if its empty so that it can actually appear. Say for instance you want it to be 50px tall set the div height to 50px.

<div id="rightflower">
<div id="divImg"></div> 
</div>

And in your style sheet just add the background and its properties, height and width, and what ever positioning you had in mind.

figure;
plot(something);

or

figure(2);
plot(something);
...
figure(3);
plot(something else);
...

etc.

ASP.NET Web API is a framework that makes it easy to build HTTP services that reach a broad range of clients, including browsers and mobile devices. ASP.NET Web API is an ideal platform for building RESTful applications on the .NET Framework.

REST

RESTs sweet spot is when you are exposing a public API over the internet to handle CRUD operations on data. REST is focused on accessing named resources through a single consistent interface.

SOAP

SOAP brings it’s own protocol and focuses on exposing pieces of application logic (not data) as services. SOAP exposes operations. SOAP is focused on accessing named operations, each implement some business logic through different interfaces.

Though SOAP is commonly referred to as “web services” this is a misnomer. SOAP has very little if anything to do with the Web. REST provides true “Web services” based on URIs and HTTP.

Reference: http://spf13.com/post/soap-vs-rest

And finally: What they could be referring to is REST vs. RPC See this: http://encosia.com/rest-vs-rpc-in-asp-net-web-api-who-cares-it-does-both/

you can use jquery as follows

apparently, regardless of how old/new the Telegram group is:

1. add a bot to the group

2. remove bot from the group

3. add bot again to the group

4. create a script file and run getUpdates method example:

    var vApiTokenTelegram = "1234567890:???>yg5GeL5PuItAOEhvdcPPELAOCCy3jBo"; // @?????Bot API token
    var vUrlTelegram = "https://api.telegram.org/bot" + vApiTokenTelegram;

    function getUpdates() {
        var response = UrlFetchApp.fetch(vUrlTelegram + "/getUpdates");
        console.log(response.getContentText());
    }

5. function shall log to the console the following:

use dnsmasq

pretending you're using a debian-based dist(ubuntu,mint..), check if it's installed with

(sudo) systemctl status dnsmasq

If it is just disabled start it with

(sudo) systemctl start dnsmasq

If you have to install it, write

(sudo) apt-get install dnsmasq

To define domains to resolve edit /etc/dnsmasq.conf like this

address=/example.com/127.0.0.1

to resolve *.example.com

! You need to reload dnsmasq to take effect for the changes !

systemctl reload dnsmasq

I know this is an old post, but in case someone else happens upon this question, one good option is Virtual Serial Port Emulator (VSPE) from Eterlogic It provides an API for creating kernel mode virtual comport devices, i.e. connectors, mappers, splitters etc.
However, some of the advertised capabilities were really not capabilities at all.

EDIT
A much better choice, Eltima. This product is fully baked. Good developer tech support. The product did all it claimed to do. Product options include both desktop applications, as well as software development kits with APIs.

Neither of these products are open source, or free. However, as other posts here have pointed out, there are other options. Here is a list of various serial utilities:

com0com (current)
com0com - With Signed Driver (old version)
Yet another place for com0com with Signed Driver (Pete's Blog)
Tactical Software
Termite
COM Port Serial Emulator
Kermit (obsolete, but still downloadable)
HWVSP3
HHD Software (free edition)

You simply need to do a SUBSTR on the string in col3....

    Select col1, col2, REPLACE(substr(col3, instr(col3, 'Client Name'), 
    (instr(col3, '|', instr(col3, 'Client Name')  -
    instr(col3, 'Client Name'))
    ),
'Client Name = ',
'')
    from Table01 

And yes, that is a bad DB design for the reasons stated in the original issue

Added a test page - to color SVG via Filter settings:

Took the idea from: https://blog.union.io/code/2017/08/10/img-svg-fill/

Try Clink. It's awesome, especially if you are used to bash keybindings and features.

(As already pointed out - there is a similar question: Is there a better Windows Console Window?)

Also, you may want to try Data::Dumper. Example:

use Data::Dumper;

You should also look at new triggers.

MySQL doesn't show the table name in the error, so you're really left in a lurch. Here's a working example:

use test;
create table blah (id int primary key AUTO_INCREMENT, data varchar(100));
create table audit_blah (audit_id int primary key AUTO_INCREMENT, action enum('INSERT','UPDATE','DELETE'), id int, data varchar(100) null);
insert into audit_blah(action, id, data) values ('INSERT', 1, 'a');
select * from blah;
select * from audit_blah;
truncate table audit_blah;

delimiter //
/* I've commented out "id" below, so the insert fails with an ambiguous error: */
create trigger ai_blah after insert on blah for each row 
begin 
  insert into audit_blah (action, /*id,*/ data) values ('INSERT', /*NEW.id,*/ NEW.data);
end;//

/* This insert is valid, but you'll get an exception from the trigger: */
insert into blah (data) values ('data1');

I got this error while trying to use the && operator inside single brackets like [ ... && ... ]. I had to switch to [[ ... && ... ]].

Don't need to download or specify anything...

Just go to the install Android Studio plugins Path and search for any file like gradle-wrapper-x.xx.jar (x.xx = version number). Copy it to a subfolder of your project root folder named : gradle.

Example : - file found gradle-wrapper-1.12.jar in plugins folder of Android Studio Install's path - my project was on D:\android_repo\myProject - created a folder into D:\android_repo\myProject\gradle - copy gradle-wrapper-1.12.jar to this folder D:\android_repo\myProject\gradle - import again my project and no more question about gradle.

So here's what I did eventually. I hope this helps someone else.

class NoDuplicatesList<E> extends LinkedList<E> {
    @Override
    public boolean add(E e) {
        if (this.contains(e)) {
            return false;
        }
        else {
            return super.add(e);
        }
    }

    @Override
    public boolean addAll(Collection<? extends E> collection) {
        Collection<E> copy = new LinkedList<E>(collection);
        copy.removeAll(this);
        return super.addAll(copy);
    }

    @Override
    public boolean addAll(int index, Collection<? extends E> collection) {
        Collection<E> copy = new LinkedList<E>(collection);
        copy.removeAll(this);
        return super.addAll(index, copy);
    }

    @Override
    public void add(int index, E element) {
        if (this.contains(element)) {
            return;
        }
        else {
            super.add(index, element);
        }
    }
}   

Have you tried :-

Sub test()

    k = Cells(Rows.Count, "A").End(xlUp).Row

    MsgBox (k)

End Sub

The /only/ catch is that if there is no data it still returns 1.

Unfortunately, you're out of luck here.

There is inherit to copy a certain value from a parent to its children, but there is no property the other way round (which would involve another selector to decide which style to revert).

You will have to revert style changes manually:

div { color: green; }

form div { color: red; }

form div div.content { color: green; }

If you have access to the markup, you can add several classes to style precisely what you need:

form div.sub { color: red; }

form div div.content { /* remains green */ }

Edit: The CSS Working Group is up to something:

div.content {
  all: revert;
}

No idea, when or if ever this will be implemented by browsers.

Edit 2: As of March 2015 all modern browsers but Safari and IE/Edge have implemented it: https://twitter.com/LeaVerou/status/577390241763467264 (thanks, @Lea Verou!)

Edit 3: default was renamed to revert.

Some ad-hoc code:

row_format ="{:>15}" * (len(teams_list) + 1)
print(row_format.format("", *teams_list))
for team, row in zip(teams_list, data):
    print(row_format.format(team, *row))

This relies on str.format() and the Format Specification Mini-Language.

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

abstract class OnTextEndEditingListener : TextView.OnEditorActionListener {

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

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

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

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

Note: I'm assuming Windows batch files as most people seem to be unaware that there are significant differences and just blindly call everything with grey text on black background DOS. Nevertheless, the first variant should work in DOS as well.

Executable configuration

The easiest way to do this is to just put the variables in a batch file themselves, each with its own set statement:

set var1=value1
set var2=value2
...

and in your main batch:

call config.cmd

Of course, that also enables variables to be created conditionally or depending on aspects of the system, so it's pretty versatile. However, arbitrary code can run there and if there is a syntax error, then your main batch will exit too. In the UNIX world this seems to be fairly common, especially for shells. And if you think about it, autoexec.bat is nothing else.

Key/value pairs

Another way would be some kind of var=value pairs in the configuration file:

var1=value1
var2=value2
...

You can then use the following snippet to load them:

for /f "delims=" %%x in (config.txt) do (set "%%x")

This utilizes a similar trick as before, namely just using set on each line. The quotes are there to escape things like <, >, &, |. However, they will themselves break when quotes are used in the input. Also you always need to be careful when further processing data in variables stored with such characters.

Generally, automatically escaping arbitrary input to cause no headaches or problems in batch files seems pretty impossible to me. At least I didn't find a way to do so yet. Of course, with the first solution you're pushing that responsibility to the one writing the config file.

String literals are not stored on the stack. Never. In fact, no objects are stored on the stack.

String literals (or more accurately, the String objects that represent them) are were historically stored in a Heap called the "permgen" heap. (Permgen is short for permanent generation.)

Under normal circumstances, String literals and much of the other stuff in the permgen heap are "permanently" reachable, and are not garbage collected. (For instance, String literals are always reachable from the code objects that use them.) However, you can configure a JVM to attempt to find and collect dynamically loaded classes that are no longer needed, and this may cause String literals to be garbage collected.

CLARIFICATION #1 - I'm not saying that Permgen doesn't get GC'ed. It does, typically when the JVM decides to run a Full GC. My point is that String literals will be reachable as long as the code that uses them is reachable, and the code will be reachable as long as the code's classloader is reachable, and for the default classloaders, that means "for ever".

CLARIFICATION #2 - In fact, Java 7 and later uses the regular heap to hold the string pool. Thus, String objects that represent String literals and intern'd strings are actually in the regular heap. (See @assylias's Answer for details.)

But I am still trying to find out thin line between storage of string literal and string created with new.

There is no "thin line". It is really very simple:

• String objects that represent / correspond to string literals are held in the string pool.
• String objects that were created by a String::intern call are held in the string pool.
• All other String objects are NOT held in the string pool.

Then there is the separate question of where the string pool is "stored". Prior to Java 7 it was the permgen heap. From Java 7 onwards it is the main heap.

To generate a shared library you need first to compile your C code with the -fPIC (position independent code) flag.

gcc -c -fPIC hello.c -o hello.o

This will generate an object file (.o), now you take it and create the .so file:

gcc hello.o -shared -o libhello.so

EDIT: Suggestions from the comments:

You can use

gcc -shared -o libhello.so -fPIC hello.c

to do it in one step. – Jonathan Leffler

I also suggest to add -Wall to get all warnings, and -g to get debugging information, to your gcc commands. – Basile Starynkevitch

You should define source code encoding, add this to the top of your script:

# -*- coding: utf-8 -*-

The reason why it works differently in console and in the IDE is, likely, because of different default encodings set. You can check it by running:

import sys
print sys.getdefaultencoding()

Also see:

• Why declare unicode by string in python?
• Changing default encoding of Python?
• Correct way to define Python source code encoding

It seems to be a python bug (that works perfectly in vim). The source of the problem is the (\s*...)+ bit. Basically , you can't do (\s*)+ which make sense , because you are trying to repeat something which can be null.

>>> re.compile(r"(\s*)+")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/re.py", line 180, in compile
    return _compile(pattern, flags)
  File "/System/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/re.py", line 233, in _compile
    raise error, v # invalid expression
sre_constants.error: nothing to repeat

However (\s*\1) should not be null, but we know it only because we know what's in \1. Apparently python doesn't ... that's weird.

It is very simple to adding an image into project and view the image. First create a folder into in your project which can contain any type of images.

Then Right click on Project ->>Go to Build Path ->> configure Build Path ->> add Class folder ->> choose your folder (which you just created for store the images) under the project name.

• A leading slash tells the browser to start at the root directory.
• If you don't have the leading slash, you're referencing from the current directory.
• If you add two dots before the leading slash, it means you're referencing the parent of the current directory.

Take the following folder structure

notice:

• the ROOT checkmark is green,
• the second checkmark is orange,
• the third checkmark is purple,
• the forth checkmark is yellow

Now in the index.html.en file you'll want to put the following markup

<p>
    <span>src="check_mark.png"</span>
    <img src="check_mark.png" />
    <span>I'm purple because I'm referenced from this current directory</span>
</p>

<p>
    <span>src="/check_mark.png"</span>
    <img src="/check_mark.png" />
    <span>I'm green because I'm referenced from the ROOT directory</span>
</p>

<p>
    <span>src="subfolder/check_mark.png"</span>
    <img src="subfolder/check_mark.png" />
    <span>I'm yellow because I'm referenced from the child of this current directory</span>
</p>

<p>
    <span>src="/subfolder/check_mark.png"</span>
    <img src="/subfolder/check_mark.png" />
    <span>I'm orange because I'm referenced from the child of the ROOT directory</span>
</p>

<p>
    <span>src="../subfolder/check_mark.png"</span>
    <img src="../subfolder/check_mark.png" />
    <span>I'm purple because I'm referenced from the parent of this current directory</span>
</p>

<p>
    <span>src="subfolder/subfolder/check_mark.png"</span>
    <img src="subfolder/subfolder/check_mark.png" />
    <span>I'm [broken] because there is no subfolder two children down from this current directory</span>
</p>

<p>
    <span>src="/subfolder/subfolder/check_mark.png"</span>
    <img src="/subfolder/subfolder/check_mark.png" />
    <span>I'm purple because I'm referenced two children down from the ROOT directory</span>
</p>

Now if you load up the index.html.en file located in the second subfolder
http://example.com/subfolder/subfolder/

This will be your output

I encountered such a situation where code was circumventing STL's api and writing to the array unsafely when someone resizes it. Adding the assert here caught it:

void Logo::add(const QVector3D &v, const QVector3D &n)
{
 GLfloat *p = m_data.data() + m_count;
 *p++ = v.x();
 *p++ = v.y();
 *p++ = v.z();
 *p++ = n.x();
 *p++ = n.y();
 *p++ = n.z();
 m_count += 6;
 Q_ASSERT( m_count <= m_data.size() );
}

A string like "Hello World" to hex format: 48656C6C6F20576F726C64.

Ah, here you go:

    std::string output;

    for (unsigned char c : input)
    {
        output.push_back(hex_digits[c >> 4]);
        output.push_back(hex_digits[c & 15]);
    }
    return output;
}

    int value = hex_values[hex_digit];
    if (value == -1) throw std::invalid_argument("invalid hex digit");
    return value;
}

std::string hex_to_string(const std::string& input)
{
    const auto len = input.length();
    if (len & 1) throw std::invalid_argument("odd length");

    std::string output;
    output.reserve(len / 2);
    for (auto it = input.begin(); it != input.end(); )
    {
        int hi = hex_value(*it++);
        int lo = hex_value(*it++);
        output.push_back(hi << 4 | lo);
    }
    return output;
}

(This assumes that a char has 8 bits, so it's not very portable, but you can take it from here.)

You can also deny access to a folder using RedirectMatch

Add the following line to htaccess

RedirectMatch 403 ^/folder/?$

This will return a 403 forbidden error for the folder ie : http://example.com/folder/ but it doest block access to files and folders inside that folder, if you want to block everything inside the folder then just change the regex pattern to ^/folder/.*$ .

Another option is mod-rewrite If url-rewrting-module is enabled you can use something like the following in root/.htaccss :

RewriteEngine on

RewriteRule ^folder/?$ - [F,L]

This will internally map a request for the folder to forbidden error page.

Open the SVG with you text editor. If you have some luck the file will contain something like:

The d attribute is what you are looking for.

If you're concatenating strings to build file paths, use the Join-Path command:

Join-Path C:\temp "MyNewFolder"

It'll automatically add the appropriate trailing / leading slashes for you, which makes things a lot easier.

String url = "http://test.com/Services/rest/{id}/Identifier";
Map<String, String> params = new HashMap<String, String>();
params.put("id", "1234");
URI uri = UriComponentsBuilder.fromUriString(url)
        .buildAndExpand(params)
        .toUri();
uri = UriComponentsBuilder
        .fromUri(uri)
        .queryParam("name", "myName")
        .build()
        .toUri();
restTemplate.exchange(uri , HttpMethod.PUT, requestEntity, class_p);

The safe way is to expand the path variables first, and then add the query parameters:

For me this resulted in duplicated encoding, e.g. a space was decoded to %2520 (space -> %20 -> %25).

I solved it by:

String url = "http://test.com/Services/rest/{id}/Identifier";
Map<String, String> params = new HashMap<String, String>();
params.put("id", "1234");
UriComponentsBuilder uriComponentsBuilder = UriComponentsBuilder.fromUriString(url);
uriComponentsBuilder.uriVariables(params);
Uri uri = uriComponentsBuilder.queryParam("name", "myName");
        .build()
        .toUri();
restTemplate.exchange(uri , HttpMethod.PUT, requestEntity, class_p);

Essentially I am using uriComponentsBuilder.uriVariables(params); to add path parameters. The documentation says:

... In contrast to UriComponents.expand(Map) or buildAndExpand(Map), this method is useful when you need to supply URI variables without building the UriComponents instance just yet, or perhaps pre-expand some shared default values such as host and port. ...

I reworked the example you provided in the js fiddle : http://jsfiddle.net/zravs3hp/

Step 1 :

I renamed your container div to overlay, as semantically this div is not a container, but an overlay. I also placed the loader div as a child of this overlay div.

The resulting html is :

<div class="overlay">
    <div id="loading-img"></div>
</div>


<div class="content">
    <div>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Ea velit provident sint aliquid eos omnis aperiam officia architecto error incidunt nemo obcaecati adipisci doloremque dicta neque placeat natus beatae cupiditate minima ipsam quaerat explicabo non reiciendis qui sit. ...</div>
    <button id="button">Submit</button>
</div>

The css of the overlay is the following

.overlay {
    background: #e9e9e9;  <- I left your 'gray' background
    display: none;        <- Not displayed by default
    position: absolute;   <- This and the following properties will
    top: 0;                  make the overlay, the element will expand
    right: 0;                so as to cover the whole body of the page
    bottom: 0;
    left: 0;
    opacity: 0.5;
}

Step 2 :

I added some dummy text so as to have something to overlay.

Step 3 :

Then, in the click handler we just need to show the overlay :

$("#button").click(function () {
    $(".overlay").show();
});

Dynamically adding map fragment to view Pager:

If you are targeting an application earlier than API level 12 make an instance of SupportedMapFragment and add it to your view page adapter.

SupportMapFragment supportMapFragment=SupportMapFragment.newInstance();
        supportMapFragment.getMapAsync(this);

API level 12 or higher support MapFragment objects

MapFragment mMapFragment=MapFragment.newInstance();
            mMapFragment.getMapAsync(this);

TLDR: brew install [email protected] See answer below for more details.

*(I’ve re-edited my answer to give a more thorough workflow for installing/using older software versions with homebrew. Feel free to add a note if you found the old version better.)

Let’s start with the simplest case:

1) Check, whether the version is already installed (but not activated)

When homebrew installs a new formula, it puts it in a versioned directory like /usr/local/Cellar/postgresql/9.3.1. Only symbolic links to this folder are then installed globally. In principle, this makes it pretty easy to switch between two installed versions. (*)

If you have been using homebrew for longer and never removed older versions (using, for example brew cleanup), chances are that some older version of your program may still be around. If you want to simply activate that previous version, brew switch is the easiest way to do this.

Check with brew info postgresql (or brew switch postgresql <TAB>) whether the older version is installed:

$ brew info postgresql
postgresql: stable 9.3.2 (bottled)
http://www.postgresql.org/
Conflicts with: postgres-xc
/usr/local/Cellar/postgresql/9.1.5 (2755 files, 37M)
  Built from source
/usr/local/Cellar/postgresql/9.3.2 (2924 files, 39M) *
  Poured from bottle
From: https://github.com/Homebrew/homebrew/commits/master/Library/Formula/postgresql.rb
# … and some more

We see that some older version is already installed. We may activate it using brew switch:

$ brew switch postgresql 9.1.5
Cleaning /usr/local/Cellar/postgresql/9.1.5
Cleaning /usr/local/Cellar/postgresql/9.3.2
384 links created for /usr/local/Cellar/postgresql/9.1.5

Let’s double-check what is activated:

$ brew info postgresql
postgresql: stable 9.3.2 (bottled)
http://www.postgresql.org/
Conflicts with: postgres-xc
/usr/local/Cellar/postgresql/9.1.5 (2755 files, 37M) *
  Built from source
/usr/local/Cellar/postgresql/9.3.2 (2924 files, 39M)
  Poured from bottle
From: https://github.com/Homebrew/homebrew/commits/master/Library/Formula/postgresql.rb
# … and some more

Note that the star * has moved to the newly activated version

(*) Please note that brew switch only works as long as all dependencies of the older version are still around. In some cases, a rebuild of the older version may become necessary. Therefore, using brew switch is mostly useful when one wants to switch between two versions not too far apart.

2) Check, whether the version is available as a tap

Especially for larger software projects, it is very probably that there is a high enough demand for several (potentially API incompatible) major versions of a certain piece of software. As of March 2012, Homebrew 0.9 provides a mechanism for this: brew tap & the homebrew versions repository.

That versions repository may include backports of older versions for several formulae. (Mostly only the large and famous ones, but of course they’ll also have several formulae for postgresql.)

brew search postgresql will show you where to look:

$ brew search postgresql
postgresql
homebrew/versions/postgresql8    homebrew/versions/postgresql91
homebrew/versions/postgresql9    homebrew/versions/postgresql92

We can simply install it by typing

$ brew install homebrew/versions/postgresql8
Cloning into '/usr/local/Library/Taps/homebrew-versions'...

Tapped 125 formula
==> Downloading http://ftp.postgresql.org/pub/source/v8.4.19/postgresql-8.4.19.tar.bz2
# …

Note that this has automatically tapped the homebrew/versions tap. (Check with brew tap, remove with brew untap homebrew/versions.) The following would have been equivalent:

$ brew tap homebrew/versions
$ brew install postgresql8

As long as the backported version formulae stay up-to-date, this approach is probably the best way to deal with older software.

3) Try some formula from the past

The following approaches are listed mostly for completeness. Both try to resurrect some undead formula from the brew repository. Due to changed dependencies, API changes in the formula spec or simply a change in the download URL, things may or may not work.

Since the whole formula directory is a git repository, one can install specific versions using plain git commands. However, we need to find a way to get to a commit where the old version was available.

a) historic times

Between August 2011 and October 2014, homebrew had a brew versions command, which spat out all available versions with their respective SHA hashes. As of October 2014, you have to do a brew tap homebrew/boneyard before you can use it. As the name of the tap suggests, you should probably only do this as a last resort.

E.g.

$ brew versions postgresql
Warning: brew-versions is unsupported and may be removed soon.
Please use the homebrew-versions tap instead:
  https://github.com/Homebrew/homebrew-versions
9.3.2    git checkout 3c86d2b Library/Formula/postgresql.rb
9.3.1    git checkout a267a3e Library/Formula/postgresql.rb
9.3.0    git checkout ae59e09 Library/Formula/postgresql.rb
9.2.4    git checkout e3ac215 Library/Formula/postgresql.rb
9.2.3    git checkout c80b37c Library/Formula/postgresql.rb
9.2.2    git checkout 9076baa Library/Formula/postgresql.rb
9.2.1    git checkout 5825f62 Library/Formula/postgresql.rb
9.2.0    git checkout 2f6cbc6 Library/Formula/postgresql.rb
9.1.5    git checkout 6b8d25f Library/Formula/postgresql.rb
9.1.4    git checkout c40c7bf Library/Formula/postgresql.rb
9.1.3    git checkout 05c7954 Library/Formula/postgresql.rb
9.1.2    git checkout dfcc838 Library/Formula/postgresql.rb
9.1.1    git checkout 4ef8fb0 Library/Formula/postgresql.rb
9.0.4    git checkout 2accac4 Library/Formula/postgresql.rb
9.0.3    git checkout b782d9d Library/Formula/postgresql.rb

As you can see, it advises against using it. Homebrew spits out all versions it can find with its internal heuristic and shows you a way to retrieve the old formulae. Let’s try it.

# First, go to the homebrew base directory
$ cd $( brew --prefix )
# Checkout some old formula
$ git checkout 6b8d25f Library/Formula/postgresql.rb
$ brew install postgresql
# … installing

Now that the older postgresql version is installed, we can re-install the latest formula in order to keep our repository clean:

$ git checkout -- Library/Formula/postgresql.rb

brew switch is your friend to change between the old and the new.

b) prehistoric times

For special needs, we may also try our own digging through the homebrew repo.

$ cd Library/Taps/homebrew/homebrew-core && git log -S'8.4.4' -- Formula/postgresql.rb

git log -S looks for all commits in which the string '8.4.4' was either added or removed in the file Library/Taps/homebrew/homebrew-core/Formula/postgresql.rb. We get two commits as a result.

commit 7dc7ccef9e1ab7d2fc351d7935c96a0e0b031552
Author: Aku Kotkavuo
Date:   Sun Sep 19 18:03:41 2010 +0300

    Update PostgreSQL to 9.0.0.

    Signed-off-by: Adam Vandenberg

commit fa992c6a82eebdc4cc36a0c0d2837f4c02f3f422
Author: David Höppner
Date:   Sun May 16 12:35:18 2010 +0200

    postgresql: update version to 8.4.4

Obviously, fa992c6a82eebdc4cc36a0c0d2837f4c02f3f422 is the commit we’re interested in. As this commit is pretty old, we’ll try to downgrade the complete homebrew installation (that way, the formula API is more or less guaranteed to be valid):

$ git checkout -b postgresql-8.4.4 fa992c6a82eebdc4cc36a0c0d2837f4c02f3f422
$ brew install postgresql
$ git checkout master
$ git branch -d postgresql-8.4.4

You may skip the last command to keep the reference in your git repository.

One note: When checking out the older commit, you temporarily downgrade your homebrew installation. So, you should be careful as some commands in homebrew might be different to the most recent version.

4) Manually write a formula

It’s not too hard and you may then upload it to your own repository. Used to be Homebrew-Versions, but that is now discontinued.

A.) Bonus: Pinning

If you want to keep a certain version of, say postgresql, around and stop it from being updated when you do the natural brew update; brew upgrade procedure, you can pin a formula:

$ brew pin postgresql

Pinned formulae are listed in /usr/local/Library/PinnedKegs/ and once you want to bring in the latest changes and updates, you can unpin it again:

$ brew unpin postgresql

I've just bumped into this myself and this variation worked for me:

db.foo.remove({**_id**: new ObjectId("4f872685a64eed5a980ca536")})

The following steps work fine on macOS Sierra 10.12.4. Note that after brew installs Docker, the docker command (symbolic link) is not available at /usr/local/bin. Running the Docker app for the first time creates this symbolic link. See the detailed steps below.

1. Install Docker.

   brew cask install docker
   

2. Launch Docker.

   • Press ? + Space to bring up Spotlight Search and enter Docker to launch Docker.
   • In the Docker needs privileged access dialog box, click OK.
   • Enter password and click OK.

   When Docker is launched in this manner, a Docker whale icon appears in the status menu. As soon as the whale icon appears, the symbolic links for docker, docker-compose, docker-credential-osxkeychain and docker-machine are created in /usr/local/bin.

   $ ls -l /usr/local/bin/docker*
   lrwxr-xr-x  1 susam  domain Users  67 Apr 12 14:14 /usr/local/bin/docker -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker
   lrwxr-xr-x  1 susam  domain Users  75 Apr 12 14:14 /usr/local/bin/docker-compose -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-compose
   lrwxr-xr-x  1 susam  domain Users  90 Apr 12 14:14 /usr/local/bin/docker-credential-osxkeychain -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-credential-osxkeychain
   lrwxr-xr-x  1 susam  domain Users  75 Apr 12 14:14 /usr/local/bin/docker-machine -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-machine
   

3. Click on the docker whale icon in the status menu and wait for it to show Docker is running.

   

4. Test that docker works fine.

   $ docker run hello-world
   Unable to find image 'hello-world:latest' locally
   latest: Pulling from library/hello-world
   78445dd45222: Pull complete
   Digest: sha256:c5515758d4c5e1e838e9cd307f6c6a0d620b5e07e6f927b07d05f6d12a1ac8d7
   Status: Downloaded newer image for hello-world:latest
   
   Hello from Docker!
   This message shows that your installation appears to be working correctly.
   
   To generate this message, Docker took the following steps:
    1. The Docker client contacted the Docker daemon.
    2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    3. The Docker daemon created a new container from that image which runs the
       executable that produces the output you are currently reading.
    4. The Docker daemon streamed that output to the Docker client, which sent it
       to your terminal.
   
   To try something more ambitious, you can run an Ubuntu container with:
    $ docker run -it ubuntu bash

5. If you are going to use docker-machine to create virtual machines, install VirtualBox.

   brew cask install virtualbox
   

   Note that if VirtualBox is not installed, then docker-machine fails with the following error.

   $ docker-machine create manager
   Running pre-create checks...
   Error with pre-create check: "VBoxManage not found. Make sure VirtualBox is installed and VBoxManage is in the path"
   

In one line, using Java 8:

list.sort(Comparator.naturalOrder());

Add cellpadding and cellspacing to solve it. Edit: Also removed double pixel border.

                </td>
            </tr>
            <tr>

                </td>
                <td>
                    Bar3
                </td>
            </tr>
            <tr >

Update:

I have added this link to my other answer how to use JWT authentication for ASP.NET Web API here for anyone interested in JWT.

We have managed to apply HMAC authentication to secure Web API, and it worked okay. HMAC authentication uses a secret key for each consumer which both consumer and server both know to hmac hash a message, HMAC256 should be used. Most of the cases, hashed password of the consumer is used as a secret key.

The message normally is built from data in the HTTP request, or even customized data which is added to HTTP header, the message might include:

1. Timestamp: time that request is sent (UTC or GMT)
2. HTTP verb: GET, POST, PUT, DELETE.
3. post data and query string,
4. URL

Under the hood, HMAC authentication would be:

Consumer sends a HTTP request to web server, after building the signature (output of hmac hash), the template of HTTP request:

User-Agent: {agent}   
Host: {host}   
Timestamp: {timestamp}
Authentication: {username}:{signature}

Example for GET request:

GET /webapi.hmac/api/values

User-Agent: Fiddler    
Host: localhost    
Timestamp: Thursday, August 02, 2012 3:30:32 PM 
Authentication: cuongle:LohrhqqoDy6PhLrHAXi7dUVACyJZilQtlDzNbLqzXlw=

The message to hash to get signature:

GET\n
Thursday, August 02, 2012 3:30:32 PM\n
/webapi.hmac/api/values\n

Example for POST request with query string (signature below is not correct, just an example)

POST /webapi.hmac/api/values?key2=value2

User-Agent: Fiddler    
Host: localhost    
Content-Type: application/x-www-form-urlencoded
Timestamp: Thursday, August 02, 2012 3:30:32 PM 
Authentication: cuongle:LohrhqqoDy6PhLrHAXi7dUVACyJZilQtlDzNbLqzXlw=

key1=value1&key3=value3

The message to hash to get signature

GET\n
Thursday, August 02, 2012 3:30:32 PM\n
/webapi.hmac/api/values\n
key1=value1&key2=value2&key3=value3

Please note that form data and query string should be in order, so the code on the server get query string and form data to build the correct message.

When HTTP request comes to the server, an authentication action filter is implemented to parse the request to get information: HTTP verb, timestamp, uri, form data and query string, then based on these to build signature (use hmac hash) with the secret key (hashed password) on the server.

The secret key is got from the database with the username on the request.

Then server code compares the signature on the request with the signature built; if equal, authentication is passed, otherwise, it failed.

The code to build signature:

private static string ComputeHash(string hashedPassword, string message)
{
    var key = Encoding.UTF8.GetBytes(hashedPassword.ToUpper());
    string hashString;

    using (var hmac = new HMACSHA256(key))
    {
        var hash = hmac.ComputeHash(Encoding.UTF8.GetBytes(message));
        hashString = Convert.ToBase64String(hash);
    }

    return hashString;
}

So, how to prevent replay attack?

Add constraint for the timestamp, something like:

servertime - X minutes|seconds  <= timestamp <= servertime + X minutes|seconds 

(servertime: time of request coming to server)

And, cache the signature of the request in memory (use MemoryCache, should keep in the limit of time). If the next request comes with the same signature with the previous request, it will be rejected.

The demo code is put as here: https://github.com/cuongle/Hmac.WebApi

Both lines are in fact correct but do subtly different things.

The first line creates a new object on the stack by calling a constructor of the format Thing(const char*).

The second one is a bit more complex. It essentially does the following

1. Create an object of type Thing using the constructor Thing(const char*)
2. Create an object of type Thing using the constructor Thing(const Thing&)
3. Call ~Thing() on the object created in step #1

to pass the event object:

<p id="p" onclick="doSomething(event)">

to get the clicked child element (should be used with event parameter:

function doSomething(e) {
    e = e || window.event;
    var target = e.target || e.srcElement;
    console.log(target);
}

to pass the element itself (DOMElement):

<p id="p" onclick="doThing(this)">

see live example on jsFiddle.

You can specify the name of the event as above, but alternatively your handler can access the event parameter as described here: "When the event handler is specified as an HTML attribute, the specified code is wrapped into a function with the following parameters". There's much more additional documentation at the link.

They key is the backslash escape character will not work with the right square bracket inside of the character class square brackets (it is interpreted as a literal backslash inside the character class square brackets). Add the right square bracket with an OR at the end like this:

select EmpNo, SampleText
from test 
where NOT regexp_like(SampleText, '[ A-Za-z0-9.{}[]|]');

You can call indexOf:

if (['a', 'b', 'c'].indexOf(str) >= 0) {
    //do something
}

if (values > 0) {
    // Do Something
}

define a String variable using the JSP tags

<%!
String test = new String();
%>

then refer to that variable in your loop as

<c:forEach items="${myParams.items}" var="currentItem" varStatus="stat">
test+= whaterver_value
</c:forEach>

You can use sed:

sed 's/,$//' file > file.nocomma

and to remove whatever last character:

sed 's/.$//' file > file.nolast

Let we have the following 2 tables(salary and employee)

Now i want those records from employee table which are not in salary. We can do this in 3 ways:

1. Using inner Join

select * from employee
where id not in(select e.id from employee e inner join salary s on e.id=s.id)

2. Using Left outer join

select * from employee e 
left outer join salary s on e.id=s.id  where s.id is null

3. Using Full Join

select * from employee e
full outer join salary s on e.id=s.id where e.id not in(select id from salary)

You can also check using below query

Select * from schema_name.table_name limit 0;

Expmple : My table has 2 columns name and pwd. Giving screenshot below.

*Using PG admin3

Unless I am greatly mistaken, the answer is, "No, there is no way."

The basic problem in situations like that is the fact that you are calling a MySQL function and you're not actually setting a value. CI escapes values so that you can do a clean insert but it does not test to see if those values happen to be calling functions like aes_encrypt, md5, or (in this case) now(). While in most situations this is wonderful, for those situations raw sql is the only recourse.

On a side, date('Y-m-d'); should work as a PHP version of NOW() for MySQL. (It won't work for all versions of SQL though).

The @CustID means it's a parameter that you will supply a value for later in your code. This is the best way of protecting against SQL injection. Create your query using parameters, rather than concatenating strings and variables. The database engine puts the parameter value into where the placeholder is, and there is zero chance for SQL injection.

    //best way to deal with this is sqlbulkcopy 
    //but if you dont like it you can do it like this
    //read current sql table in an adapter
    //add rows of datatable , I have mentioned a simple way of it
    //and finally updating changes

    Dim cnn As New SqlConnection("connection string")        
    cnn.Open()
    Dim cmd As New SqlCommand("select * from  sql_server_table", cnn)
    Dim da As New SqlDataAdapter(cmd)       
    Dim ds As New DataSet()
    da.Fill(ds, "sql_server_table")
    Dim cb As New SqlCommandBuilder(da)        

    //for each datatable row
    ds.Tables("sql_server_table").Rows.Add(COl1, COl2)

    da.Update(ds, "sql_server_table")

You must use one of the following ways:

    string s = @"loooooooooooooooooooooooong loooooong
                  long long long";

string s = "loooooooooong loooong" +
           " long long" ;

I Enabling Swagger ui with Spring websecurity:

If you have enabled Spring Websecurity by default it will block all the requests to your application and returns 401. However for the swagger ui to load in the browser swagger-ui.html makes several calls to collect data. The best way to debug is open swagger-ui.html in a browser(like google chrome) and use developer options('F12' key ). You can see several calls made when the page loads and if the swagger-ui is not loading completely probably some of them are failing.

you may need to tell Spring websecurity to ignore authentication for several swagger path patterns. I am using swagger-ui 2.9.2 and in my case below are the patterns that i had to ignore:

However if you are using a different version your's might change. you may have to figure out yours with developer option in your browser as i said before.

@Configuration
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {
@Override
public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers("/v2/api-docs", "/configuration/ui", 
            "/swagger-resources/**", "/configuration/**", "/swagger-ui.html"
            , "/webjars/**", "/csrf", "/");
}
}

II Enabling swagger ui with interceptor

Generally you may not want to intercept requests that are made by swagger-ui.html. To exclude several patterns of swagger below is the code:

Most of the cases pattern for web security and interceptor will be same.

@Configuration
@EnableWebMvc
public class RetrieveCiamInterceptorConfiguration implements WebMvcConfigurer {

@Autowired
RetrieveInterceptor validationInterceptor;

@Override
public void addInterceptors(InterceptorRegistry registry) {

    registry.addInterceptor(validationInterceptor).addPathPatterns("/**")
    .excludePathPatterns("/v2/api-docs", "/configuration/ui", 
            "/swagger-resources/**", "/configuration/**", "/swagger-ui.html"
            , "/webjars/**", "/csrf", "/");
}

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("swagger-ui.html")
      .addResourceLocations("classpath:/META-INF/resources/");

    registry.addResourceHandler("/webjars/**")
      .addResourceLocations("classpath:/META-INF/resources/webjars/");
}

}

Since you may have to enable @EnableWebMvc to add interceptors you may also have to add resource handlers to swagger similar to i have done in the above code snippet.

Using -XX:+UseParNewGC along with -XX:+UseConcMarkSweepGC, will cause higher pause time for Minor GCs, when compared to -XX:+UseParallelGC.

This is because, promotion of objects from Young to Old Generation will require running a Best-Fit algorithm (due to old generation fragmentation) to find an address for this object.
Running such an algorithm is not required when using -XX:+UseParallelGC, as +UseParallelGC can be configured only with MarkandCompact Collector, in which case there is no fragmentation.

The variable a is pointing at the object "Dog". It's best to think of the variable in Python as a tag. You can move the tag to different objects which is what you did when you changed a = "dog" to a = "dog eats treats".

However, immutability refers to the object, not the tag.

If you tried a[1] = 'z' to make "dog" into "dzg", you would get the error:

TypeError: 'str' object does not support item assignment" 

because strings don't support item assignment, thus they are immutable.

You can't use Microsoft.Office.Interop.Excel without having ms office installed.

Just search in google for some libraries, which allows to modify xls or xlsx:

• http://code.google.com/p/excellibrary/
• http://simpleooxml.codeplex.com/ (only xlsx)

Use the ArrayList copy constructor, then sort that.

List oldList;
List newList = new ArrayList(oldList);
Collections.sort(newList);

After making the copy, any changes to newList do not affect oldList.

Note however that only the references are copied, so the two lists share the same objects, so changes made to elements of one list affect the elements of the other.

I've built a really simple package called "Pusheh". Using it, you can clear a directory or remove a directory completely (Github link). It's available on Packagist, also.

For instance, if you want to clear Temp directory, you can do:

Pusheh::clearDir("Temp");

// Or you can remove the directory completely
Pusheh::removeDirRecursively("Temp");

If you're interested, see the wiki.

Although this is an old document, but it helped me resolve the problem of 'HintPath' being ignored on another machine. It was because the referenced DLL needed to be in source control as well:

https://msdn.microsoft.com/en-us/library/ee817675.aspx#tdlg_ch4_includeoutersystemassemblieswithprojects

Excerpt:

To include and then reference an outer-system assembly
1. In Solution Explorer, right-click the project that needs to reference the assembly,,and then click Add Existing Item.
2. Browse to the assembly, and then click OK. The assembly is then copied into the project folder and automatically added to VSS (assuming the project is already under source control).
3. Use the Browse button in the Add Reference dialog box to set a file reference to assembly in the project folder.

The best way is the clearest, most robust way: *

Thread.currentThread().equals( Looper.getMainLooper().getThread() )

Or, if the runtime platform is API level 23 (Marshmallow 6.0) or higher:

Looper.getMainLooper().isCurrentThread()

See the Looper API. Note that calling Looper.getMainLooper() involves synchronization (see the source). You might want to avoid the overhead by storing the return value and reusing it.

If you guys are facing "Permission Denial: starting Intent..." error or if the app is getting crash without any reason during launching the app - Then use this single line code in Manifest

android:exported="true"

Please be careful with finish(); , if you missed out it the app getting frozen. if its mentioned the app would be a smooth launcher.

finish();

The other solution only works for two activities that are in the same application. In my case, application B doesn't know class com.example.MyExampleActivity.class in the code, so compile will fail.

I searched on the web and found something like this below, and it works well.

Intent intent = new Intent();
intent.setComponent(new ComponentName("com.example", "com.example.MyExampleActivity"));
startActivity(intent);

You can also use the setClassName method:

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setClassName("com.hotfoot.rapid.adani.wheeler.android", "com.hotfoot.rapid.adani.wheeler.android.view.activities.MainActivity");
startActivity(intent);
finish();

You can also pass the values from one app to another app :

Intent launchIntent = getApplicationContext().getPackageManager().getLaunchIntentForPackage("com.hotfoot.rapid.adani.wheeler.android.LoginActivity");
if (launchIntent != null) {
    launchIntent.putExtra("AppID", "MY-CHILD-APP1");
    launchIntent.putExtra("UserID", "MY-APP");
    launchIntent.putExtra("Password", "MY-PASSWORD");
    startActivity(launchIntent);
    finish();
} else {
    Toast.makeText(getApplicationContext(), " launch Intent not available", Toast.LENGTH_SHORT).show();
}

Maybe this is what you need...

If your path to view is true first try to config:cache and route:cache if nothing changed check your resource path permission are true.

example: your can do it in ubuntu with :

sudo chgrp -R www-data resources/views
sudo usermod -a -G www-data $USER

If you just want to see what's in the database without installing anything extra, you might already have SQLite CLI on your system. To check, open a command prompt and try:

sqlite3 database.sqlite

Replace database.sqlite with your database file. Then, if the database is small enough, you can view the entire contents with:

sqlite> .dump

Or you can list the tables:

sqlite> .tables

Regular SQL works here as well:

sqlite> select * from some_table;

Replace some_table as appropriate.

// Prefs.h
extern NSString * const RAHUL;

// Prefs.m
NSString * const RAHUL = @"rahul";

Use bind function instead. Make it more friendly.

Example:

var clickHandler = "click";

if('ontouchstart' in document.documentElement){
    clickHandler = "touchstart";
}

$(".button").bind(clickHandler,function(){
    alert('Visible on touch and non-touch enabled devices');
});

window.setInterval(function() {
 alert('test');
}, 10000);

window.setInterval

Calls a function repeatedly, with a fixed time delay between each call to that function.

you can use the function

bind_rows(a,b)

from the dplyr library

You are mixing code that was compiled with /MD (use DLL version of CRT) with code that was compiled with /MT (use static CRT library). That cannot work, all source code files must be compiled with the same setting. Given that you use libraries that were pre-compiled with /MD, almost always the correct setting, you must compile your own code with this setting as well.

Project + Properties, C/C++, Code Generation, Runtime Library.

Beware that these libraries were probably compiled with an earlier version of the CRT, msvcr100.dll is quite new. Not sure if that will cause trouble, you may have to prevent the linker from generating a manifest. You must also make sure to deploy the DLLs you need to the target machine, including msvcr100.dll

Open a command prompt.

Go to the directory where you have your .java files

Create a directory build

Run java compilation from the command line

javac -d ./build *.java

if there are no errors, in the build directory you should have your class tree

move to the build directory and do a

jar cvf YourJar.jar *

For adding manifest check jar command line switches

string::c.str() returns a string of type const char * as seen here

A quick fix: try casting printfunc(num,addr,(char *)data.str().c_str());

While the above may work, it is undefined behaviour, and unsafe.

Here's a nicer solution using templates:

char * my_argument = const_cast<char*> ( ...c_str() );

This is a very old question, but my answer may help someone.

• In the encrypt method, don't forget to encode your string to Base64
• In the decrypt method, don't forget to decode your string to Base64

Below is the working code

    import java.util.Arrays;
    import java.util.Base64;

    import javax.crypto.Cipher;
    import javax.crypto.SecretKey;
    import javax.crypto.spec.SecretKeySpec;

    public class EncryptionDecryptionUtil {

    public static String encrypt(final String secret, final String data) {


        byte[] decodedKey = Base64.getDecoder().decode(secret);

        try {
            Cipher cipher = Cipher.getInstance("AES");
            // rebuild key using SecretKeySpec
            SecretKey originalKey = new SecretKeySpec(Arrays.copyOf(decodedKey, 16), "AES");
            cipher.init(Cipher.ENCRYPT_MODE, originalKey);
            byte[] cipherText = cipher.doFinal(data.getBytes("UTF-8"));
            return Base64.getEncoder().encodeToString(cipherText);
        } catch (Exception e) {
            throw new RuntimeException(
                    "Error occured while encrypting data", e);
        }

    }

    public static String decrypt(final String secret,
            final String encryptedString) {


        byte[] decodedKey = Base64.getDecoder().decode(secret);

        try {
            Cipher cipher = Cipher.getInstance("AES");
            // rebuild key using SecretKeySpec
            SecretKey originalKey = new SecretKeySpec(Arrays.copyOf(decodedKey, 16), "AES");
            cipher.init(Cipher.DECRYPT_MODE, originalKey);
            byte[] cipherText = cipher.doFinal(Base64.getDecoder().decode(encryptedString));
            return new String(cipherText);
        } catch (Exception e) {
            throw new RuntimeException(
                    "Error occured while decrypting data", e);
        }
    }


    public static void main(String[] args) {

        String data = "This is not easy as you think";
        String key = "---------------------------------";
        String encrypted = encrypt(key, data);
        System.out.println(encrypted);
        System.out.println(decrypt(key, encrypted));
      }
  }

For Generating Key you can use below class

    import java.security.NoSuchAlgorithmException;
import java.security.SecureRandom;
import java.util.Base64;

import javax.crypto.KeyGenerator;
import javax.crypto.SecretKey;

public class SecretKeyGenerator {

    public static void main(String[] args) throws NoSuchAlgorithmException {

        KeyGenerator keyGenerator = KeyGenerator.getInstance("AES");

        SecureRandom secureRandom = new SecureRandom();
        int keyBitSize = 256;
        keyGenerator.init(keyBitSize, secureRandom);

        SecretKey secretKey = keyGenerator.generateKey();

 System.out.println(Base64.getEncoder().encodeToString(secretKey.getEncoded()));
    }

}

Since it is not possible to make an async constructor, I use a static async method that returns a class instance created by a private constructor. This is not elegant but it works ok.

public class ViewModel       
{       
    public ObservableCollection<TData> Data { get; set; }       

    //static async method that behave like a constructor       
    async public static Task<ViewModel> BuildViewModelAsync()  
    {       
        ObservableCollection<TData> tmpData = await GetDataTask();  
        return new ViewModel(tmpData);
    }       

    // private constructor called by the async method
    private ViewModel(ObservableCollection<TData> Data)
    {
        this.Data = Data;   
    }
}  

Can you use date as a factor?

Yes, but you probably shouldn't.

...or should you use as.Date on a date column?

Yes.

Which leads us to this:

library(scales)
df$Month <- as.Date(df$Month)
ggplot(df, aes(x = Month, y = AvgVisits)) + 
  geom_bar(stat = "identity") +
  theme_bw() +
  labs(x = "Month", y = "Average Visits per User") +
  scale_x_date(labels = date_format("%m-%Y"))

in which I've added stat = "identity" to your geom_bar call.

In addition, the message about the binwidth wasn't an error. An error will actually say "Error" in it, and similarly a warning will always say "Warning" in it. Otherwise it's just a message.

I find it useful, because when I didn't know about env, before I started to write script I was doing this:

type nodejs > scriptname.js #or any other environment

and then I was modifying that line in the file into shebang.
I was doing this, because I didn't always remember where is nodejs on my computer -- /usr/bin/ or /bin/, so for me env is very useful. Maybe there are details with this, but this is my reason

while(something.hasnext())
do something...
   if(contains something to process){
      do something...
      break;
   }
}

Just use the break statement;

For eg:this just prints "Breaking..."

while (true) {
     if (true) {
         System.out.println("Breaking...");
         break;
     }
     System.out.println("Did this print?");
}

You can also set a Java property, i.e. environment variable, on the command line and easily use it anywhere in your code.

The command line would be done this way:

c:/> java -jar -Dmyvar=enwiki-20111007-pages-articles.xml wiki2txt

and the java code accesses the value like this:

String context = System.getProperty("myvar"); 

See this question about argument passing in Java.

Trying to depict with venn diagrams for better understanding..

Left Semi join : A semi join returns values from the left side of the relation that has a match with the right. It is also referred to as a left semi join.

Note : There is another thing called left anti join : An anti join returns values from the left relation that has no match with the right. It is also referred to as a left anti join.

Inner join : It selects rows that have matching values in both relations.

I am in the process of developing a number of custom Plugins for CKEditor and here's my survival pack of bookmarks:

• A StackOverflow post linking to and talking about a plugins tutorial that got me started (Tim Down already mentioned this)
• A number of ready-made plugins for FCK and CKEditor that may improve one's understanding of the system
• The Blog of AlfonsoML, one of the developers, lots of valuable stuff there, e.g. Plugin localization in CKEditor
• Interaction between dialog buttons and a IFrame dialog, with input from Garry Yao, one of the developers
• The forums are not as bad as they look, there are some hidden gems there. Make sure you search there, well, if not first, then at least second or third.

For your purpose, I would recommend look at one of the plugins in the _source/plugins directory, for example the "print" button. Adding a simple Javascript function is quite easy to achieve. You should be able to duplicate the print plugin (take the directory from _source into the actual plugins/ directory, worry about minification later), rename it, rename every mention of "print" within it, give the button a proper name you use later in your toolbar setup to include the button, and add your function.

Although overloading paradigm is not fully supported by PHP the same (or very similar) effect can be achieved with default parameter(s) (as somebody mentioned before).

If you define your function like this:

function f($p=0)
{
  if($p)
  {
    //implement functionality #1 here
  }
  else
  {
    //implement functionality #2 here
  }
}

When you call this function like:

f();

you'll get one functionality (#1), but if you call it with parameter like:

f(1);

you'll get another functionality (#2). That's the effect of overloading - different functionality depending on function's input parameter(s).

I know, somebody will ask now what functionality one will get if he/she calls this function as f(0).

Also, be wary of additional top level domains that aren't included in some of the answers above.

For example .info, .biz, .ru, .online will throw some sentence parsers but aren't included above.

Here's some info on frequency of top level domains: https://www.westhost.com/blog/the-most-popular-top-level-domains-in-2017/

That could be addressed by editing the code above to read:

alphabets= "([A-Za-z])"
prefixes = "(Mr|St|Mrs|Ms|Dr)[.]"
suffixes = "(Inc|Ltd|Jr|Sr|Co)"
starters = "(Mr|Mrs|Ms|Dr|He\s|She\s|It\s|They\s|Their\s|Our\s|We\s|But\s|However\s|That\s|This\s|Wherever)"
acronyms = "([A-Z][.][A-Z][.](?:[A-Z][.])?)"
websites = "[.](com|net|org|io|gov|ai|edu|co.uk|ru|info|biz|online)"

This will work for a multiple row df having the dataframe as df with the same name of the columns in the df as the db.

tuples = list(df.itertuples(index=False, name=None))

columns_list = df.columns.tolist()
marks = ['?' for _ in columns_list]
columns_list = f'({(",".join(columns_list))})'
marks = f'({(",".join(marks))})'

table_name = 'whateveryouwant'

std::map::find returns an iterator to the found element (or to the end() if the element was not found). So long as the map is not const, you can modify the element pointed to by the iterator:

std::map<char, int> m;
m.insert(std::make_pair('c', 0));  // c is for cookie

std::map<char, int>::iterator it = m.find('c'); 
if (it != m.end())
    it->second = 42;
