You are not seeding the number.

Use This:

#include <iostream>
#include <ctime>

using namespace std;

int main()
{
    srand(static_cast<unsigned int>(time(0)));
    cout << (rand() % 100) << endl;
    return 0;
}

You only need to seed it once though. Basically don't seed it every random number.

You can use upstream headers (named starting with $http_) and additional custom headers. For example:

add_header X-Upstream-01 $http_x_upstream_01;
add_header X-Hdr-01  txt01;

next, go to console and make request with user's header:

curl -H "X-Upstream-01: HEADER1" -I http://localhost:11443/

the response contains X-Hdr-01, seted by server and X-Upstream-01, seted by client:

HTTP/1.1 200 OK
Server: nginx/1.8.0
Date: Mon, 30 Nov 2015 23:54:30 GMT
Content-Type: text/html;charset=UTF-8
Connection: keep-alive
X-Hdr-01: txt01
X-Upstream-01: HEADER1

Simply add

this.WindowState = FormWindowState.Minimized;
this.ShowInTaskbar = false;

to your form object. You will see only an icon at system tray.

Here's an approach which (ab)uses vim:

vim -c :sort -c :wq -E -s "${filename}"

The -c :sort -c :wq portion invokes commands to vim after the file opens. -E and -s are necessary so that vim executes in a "headless" mode which doesn't draw to the terminal.

This has almost no benefits over the sort -o "${filename}" "${filename}" approach except that it only takes the filename argument once.

This was useful for me to implement a formatter directive in a nanorc entry for .gitignore files. Here's what I used for that:

syntax "gitignore" "\.gitignore$"

formatter vim -c :sort -c :wq -E -s

I resolved it by deleting Gemfile.lock and gem install bundler:2.2.0

It's been quite sometime since I asked this question. Now I understand it more clearly, I'm going to put a more complete answer to help others.

In Web API, it's very simple to remember how parameter binding is happening.

• if you POST simple types, Web API tries to bind it from the URL

• if you POST complex type, Web API tries to bind it from the body of the request (this uses a media-type formatter).

• If you want to bind a complex type from the URL, you'll use [FromUri] in your action parameter. The limitation of this is down to how long your data going to be and if it exceeds the url character limit.

  public IHttpActionResult Put([FromUri] ViewModel data) { ... }

• If you want to bind a simple type from the request body, you'll use [FromBody] in your action parameter.

  public IHttpActionResult Put([FromBody] string name) { ... }

as a side note, say you are making a PUT request (just a string) to update something. If you decide not to append it to the URL and pass as a complex type with just one property in the model, then the data parameter in jQuery ajax will look something like below. The object you pass to data parameter has only one property with empty property name.

var myName = 'ABC';
$.ajax({url:.., data: {'': myName}});

and your web api action will look something like below.

public IHttpActionResult Put([FromBody] string name){ ... }

This asp.net page explains it all. http://www.asp.net/web-api/overview/formats-and-model-binding/parameter-binding-in-aspnet-web-api

I made this plugin. There is some css interference taking place.

It's your border on the slider itself. Either use

box-sizing: border-box 

to absorb the border width, or put the border on the content inside the slide.

If you get this issue, then either

• the formControlName is not located on the value accessor element.
• or you're not importing the module for that element.

I tried all the solutions mentioned above, but I was still facing the issue. Finally I stumbled upon the following which resolved the issue.

(On MacOS) Went to Preferences -> Memory Settings -> Find existing grade demon(s) -> Stopped all of them.

Try this simple select:

select * 
from artists 
where name like "a%"

One thing to point out, though, is that String.trim has a peculiar definition of "whitespace". It does not remove Unicode whitespace, but also removes ASCII control characters that you may not consider whitespace.

This method may be used to trim whitespace from the beginning and end of a string; in fact, it trims all ASCII control characters as well.

If possible, you may want to use Commons Lang's StringUtils.strip(), which also handles Unicode whitespace (and is null-safe, too).

Try this,

$('td').click(function(){
   var row_index = $(this).parent().index();
   var col_index = $(this).index();
});

If you need the index of table contain td then you can change it to

var row_index = $(this).parent('table').index(); 

Try

let bytes = [65,108,105,99,101,39,115,32,65,100,118,101,110,116,117,114,101];_x000D_
_x000D_
let base64data = btoa(String.fromCharCode.apply(null, bytes));_x000D_
_x000D_
let a = document.createElement('a');_x000D_
a.href = 'data:;base64,' + base64data;_x000D_
a.download = 'binFile.txt'; _x000D_
a.click();

I convert here binary data to base64 (for bigger data conversion use this) - during downloading browser decode it automatically and save raw data in file. 2020.06.14 I upgrade Chrome to 83.0 and above SO snippet stop working (probably due to sandbox security restrictions) - but JSFiddle version works - here

First of all, slower with respect to what? C? Python? Let's get some numbers at the Computer Language Benchmarks Game:

• Ruby 1.9 vs. Python3 within the same order of magnitude
• Ruby 1.9 vs. PHP within the same order of magnitude
• Ruby 1.9 vs. Java 6 server up to two orders of magnitude slower!
• Ruby 1.9 vs. C (gcc) up to two orders of magnitude slower!
• ...

Why is Ruby considered slow?

Depends on whom you ask. You could be told that:

• Ruby is an interpreted language and interpreted languages will tend to be slower than compiled ones
• Ruby uses garbage collection (though C#, which also uses garbage collection, comes out two orders of magnitude ahead of Ruby, Python, PHP etc. in the more algorithmic, less memory-allocation-intensive benchmarks above)
• Ruby method calls are slow (although, because of duck typing, they are arguably faster than in strongly typed interpreted languages)
• Ruby (with the exception of JRuby) does not support true multithreading
• etc.

But, then again, slow with respect to what? Ruby 1.9 is about as fast as Python and PHP (within a 3x performance factor) when compared to C (which can be up to 300x faster), so the above (with the exception of threading considerations, should your application heavily depend on this aspect) are largely academic.

What are your options as a Ruby programmer if you want to deal with this "slowness"?

Write for scalability and throw more hardware at it (e.g. memory)

Which version of Ruby would best suit an application like Stack Overflow where speed is critical and traffic is intense?

Well, REE (combined with Passenger) would be a very good candidate.

UPDATE: Turned my solution into a stand-alone python script.

This solution has saved me more than once. Hopefully others find it useful. This python script will find any jupyter kernel using more than cpu_threshold CPU and prompts the user to send a SIGINT to the kernel (KeyboardInterrupt). It will keep sending SIGINT until the kernel's cpu usage goes below cpu_threshold. If there are multiple misbehaving kernels it will prompt the user to interrupt each of them (ordered by highest CPU usage to lowest). A big thanks goes to gcbeltramini for writing code to find the name of a jupyter kernel using the jupyter api. This script was tested on MACOS with python3 and requires jupyter notebook, requests, json and psutil.

Put the script in your home directory and then usage looks like:

python ~/interrupt_bad_kernels.py
Interrupt kernel chews cpu.ipynb; PID: 57588; CPU: 2.3%? (y/n) y

Script code below:

from os import getpid, kill

Angular doesn't really provide what you are looking for out of the box. What i would do to accomplish what you're after is use the following add ons

UI Router & UI Router Extras

These two will provide you with state based routing and sticky states, you can tab between states and all information will be saved as the scope "stays alive" so to speak.

Check the documentation on both as it's pretty straight forward, ui router extras also has a good demonstration of how sticky states works.

Example of each kind listed in the question:

ListIterationExample.java

import java.util.*;

public class ListIterationExample {

     public static void main(String []args){
        List<Integer> numbers = new ArrayList<Integer>();

        // populates list with initial values
        for (Integer i : Arrays.asList(0,1,2,3,4,5,6,7))
            numbers.add(i);
        printList(numbers);         // 0,1,2,3,4,5,6,7

        // replaces each element with twice its value
        for (int index=0; index < numbers.size(); index++) {
            numbers.set(index, numbers.get(index)*2); 
        }
        printList(numbers);         // 0,2,4,6,8,10,12,14

        // does nothing because list is not being changed
        for (Integer number : numbers) {
            number++; // number = new Integer(number+1);
        }
        printList(numbers);         // 0,2,4,6,8,10,12,14  

        // same as above -- just different syntax
        for (Iterator<Integer> iter = numbers.iterator(); iter.hasNext(); ) {
            Integer number = iter.next();
            number++;
        }
        printList(numbers);         // 0,2,4,6,8,10,12,14

        // ListIterator<?> provides an "add" method to insert elements
        // between the current element and the cursor
        for (ListIterator<Integer> iter = numbers.listIterator(); iter.hasNext(); ) {
            Integer number = iter.next();
            iter.add(number+1);     // insert a number right before this
        }
        printList(numbers);         // 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15

        // Iterator<?> provides a "remove" method to delete elements
        // between the current element and the cursor
        for (Iterator<Integer> iter = numbers.iterator(); iter.hasNext(); ) {
            Integer number = iter.next();
            if (number % 2 == 0)    // if number is even 
                iter.remove();      // remove it from the collection
        }
        printList(numbers);         // 1,3,5,7,9,11,13,15

        // ListIterator<?> provides a "set" method to replace elements
        for (ListIterator<Integer> iter = numbers.listIterator(); iter.hasNext(); ) {
            Integer number = iter.next();
            iter.set(number/2);     // divide each element by 2
        }
        printList(numbers);         // 0,1,2,3,4,5,6,7
     }

     public static void printList(List<Integer> numbers) {
        StringBuilder sb = new StringBuilder();
        for (Integer number : numbers) {
            sb.append(number);
            sb.append(",");
        }
        sb.deleteCharAt(sb.length()-1); // remove trailing comma
        System.out.println(sb.toString());
     }
}

You do

printf ("Hi %s,</br />", $name);

before setting the cookies, which isn't allowed. You can't send any output before the headers, not even a blank line.

If the src is already set then the event is firing in the cached case before you even get the event handler bound. So, you should trigger the event based off .complete also.

code sample:

$("img").one("load", function() {
   //do stuff
}).each(function() {
   if(this.complete || /*for IE 10-*/ $(this).height() > 0)
     $(this).load();
});

I think a solution is to put count in back ticks

.filter("`count` >= 2")

Maybe it's better to use a String representation than an integer, because the String is still valid if values are added to the enum. You can use the enum's name() method to convert the enum value to a String an the enum's valueOf() method to create an enum representation from the String again. The following example shows how to convert the enum value to String and back (ValueType is an enum):

ValueType expected = ValueType.FLOAT;
String value = expected.name();

System.out.println("Name value: " + value);

ValueType actual = ValueType.valueOf(value);

if(expected.equals(actual)) System.out.println("Values are equal");

Try this:

{[0-9]{1,3}:[0-9]{1,3}}

The {1,3} means "match between 1 and 3 of the preceding characters".

Not exactly answering the question, but faced with the same problem I ended up doing this:

UPDATE people_exit SET last_name = SUBSTRING_INDEX(fullname,' ',-1)
UPDATE people_exit SET middle_name = TRIM(SUBSTRING_INDEX(SUBSTRING_INDEX(fullname,last_name,1),' ',-2))
UPDATE people_exit SET middle_name = '' WHERE CHAR_LENGTH(middle_name)>3 
UPDATE people_exit SET first_name = SUBSTRING_INDEX(fullname,concat(middle_name,' ',last_name),1)
UPDATE people_exit SET first_name = middle_name WHERE first_name = ''
UPDATE people_exit SET middle_name = '' WHERE first_name = middle_name

Maybe it's obvious for you guys but I scratched my head for a while because the folder didn't show up in the files app. I actually needed to store something in the folder. you could achieve this by

• saving some files into your document directory of the app
• move something from iCloud Drive to your app (in the move dialog the folder will show up). As soon as there are no files in your folder anymore, it's gonna disappear from the "on my iPad tab".

As @gaurang171 mentioned, we can use .closest() which will return the first ancestor, or the closest to our delete button, and use .remove() to remove it.

This is how we can implement it using jQuery click event instead of using JavaScript onclick.

This question didn't specifically address my concerns (outlined here) but in case anyone wants to do this with a parameterized number of columns and no coercion:

> require(dplyr)
> dbNames <- c('a','b','c','d')
> emptyTableOut <- 
    data.frame(
        character(), 
        matrix(integer(), ncol = 3, nrow = 0), stringsAsFactors = FALSE
    ) %>% 
    setNames(nm = c(dbNames))
> glimpse(emptyTableOut)
Observations: 0
Variables: 4
$ a <chr> 
$ b <int> 
$ c <int> 
$ d <int>

As divibisan states on the linked question,

...the reason [coercion] occurs [when cbinding matrices and their constituent types] is that a matrix can only have a single data type. When you cbind 2 matrices, the result is still a matrix and so the variables are all coerced into a single type before converting to a data.frame

I hesitate to post this answer, it is actually technically possible but it doesn't work that well in practice. The version numbers of the CLR and the core framework assemblies were not changed in 4.5. You still target v4.0.30319 of the CLR and the framework assembly version numbers are still 4.0.0.0. The only thing that's distinctive about the assembly manifest when you look at it with a disassembler like ildasm.exe is the presence of a [TargetFramework] attribute that says that 4.5 is needed, that would have to be altered. Not actually that easy, it is emitted by the compiler.

The biggest difference is not that visible, Microsoft made a long-overdue change in the executable header of the assemblies. Which specifies what version of Windows the executable is compatible with. XP belongs to a previous generation of Windows, started with Windows 2000. Their major version number is 5. Vista was the start of the current generation, major version number 6.

.NET compilers have always specified the minimum version number to be 4.00, the version of Windows NT and Windows 9x. You can see this by running dumpbin.exe /headers on the assembly. Sample output looks like this:

OPTIONAL HEADER VALUES
             10B magic # (PE32)
            ...
            4.00 operating system version
            0.00 image version
            4.00 subsystem version              // <=== here!!
               0 Win32 version
            ...

What's new in .NET 4.5 is that the compilers change that subsystem version to 6.00. A change that was over-due in large part because Windows pays attention to that number, beyond just checking if it is small enough. It also turns on appcompat features since it assumes that the program was written to work on old versions of Windows. These features cause trouble, particularly the way Windows lies about the size of a window in Aero is troublesome. It stops lying about the fat borders of an Aero window when it can see that the program was designed to run on a Windows version that has Aero.

You can alter that version number and set it back to 4.00 by running Editbin.exe on your assemblies with the /subsystem option. This answer shows a sample postbuild event.

That's however about where the good news ends, a significant problem is that .NET 4.5 isn't very compatible with .NET 4.0. By far the biggest hang-up is that classes were moved from one assembly to another. Most notably, that happened for the [Extension] attribute. Previously in System.Core.dll, it got moved to Mscorlib.dll in .NET 4.5. That's a kaboom on XP if you declare your own extension methods, your program says to look in Mscorlib for the attribute, enabled by a [TypeForwardedTo] attribute in the .NET 4.5 version of the System.Core reference assembly. But it isn't there when you run your program on .NET 4.0

And of course there's nothing that helps you stop using classes and methods that are only available on .NET 4.5. When you do, your program will fail with a TypeLoadException or MissingMethodException when run on 4.0

Just target 4.0 and all of these problems disappear. Or break that logjam and stop supporting XP, a business decision that programmers cannot often make but can certainly encourage by pointing out the hassles that it is causing. There is of course a non-zero cost to having to support ancient operating systems, just the testing effort is substantial. A cost that isn't often recognized by management, Windows compatibility is legendary, unless it is pointed out to them. Forward that cost to the client and they tend to make the right decision a lot quicker :) But we can't help you with that.

You could make the Hash key something along the lines of a 'product category' id, then the range key as a combination of a timestamp with a unique id appended on the end. That way you know the hash key and can still query the date with greater than.

May be answer would depend on what problem you have with using iterator? may be use

i = 100
while i:
    print i
    i-=1

or

def loop(N, doSomething):
    if not N:
        return
    print doSomething(N)
    loop(N-1, doSomething)

loop(100, lambda a:a)

but frankly i see no point in using such approaches

The .bashrc file is in your user home directory (~/.bashrc or ~vagrant/.bashrc both resolve to the same path), inside the VM's filesystem. This file is invisible on the host machine, so you can't use any Windows editors to edit it directly.

You have two simple choices:

1. Learn how to use a console-based text editor. My favourite is vi (or vim), which takes 15 minutes to learn the basics and is much quicker for simple edits than anything else.

   vi .bashrc

2. Copy .bashrc out to /vagrant (which is a shared directory) and edit it using your Windows editors. Make sure not to save it back with any extensions.

   cp .bashrc /vagrant ... edit using your host machine ... cp /vagrant/.bashrc .

I'd recommend getting to know the command-line based editors. Once you're working inside the VM, it's best to stay there as otherwise you might just get confused.

You (the vagrant user) are the owner of your home .bashrc so you do have permissions to edit it.

Once edited, you can execute it by typing source .bashrc I prefer to logout and in again (there may be more than one file executed on login).

You don't really need the MockitoAnnotations.initMocks(this); if you're using mockito 1.9 ( or newer ) - all you need is this:

@InjectMocks
private MyTestObject testObject;

@Mock
private MyDependentObject mockedObject;

The @InjectMocks annotation will inject all your mocks to the MyTestObject object.

The stdout of the process started by the docker container is available through the docker logs $containerid command (use -f to keep it going forever). Another option would be to stream the logs directly through the docker remote API.

For accessing log files (only if you must, consider logging to stdout or other standard solution like syslogd) your only real-time option is to configure a volume (like Marcus Hughes suggests) so the logs are stored outside the container and available for processing from the host or another container.

If you do not need real-time access to the logs, you can export the files (in tar format) with docker export

I only write shell scripts now and then and fall out of practice, so any feedback is appreciated.

Using the strategy proposed by @Arvid Requate, we noticed some user errors. A user who forgets to include a value will accidentally have the next option's name treated as a value:

./getopts_test.sh --loglevel= --toc=TRUE

will cause the value of "loglevel" to be seen as "--toc=TRUE". This can be avoided.

I adapted some ideas about checking user error for CLI from http://mwiki.wooledge.org/BashFAQ/035 discussion of manual parsing. I inserted error checking into handling both "-" and "--" arguments.

Then I started fiddling around with the syntax, so any errors in here are strictly my fault, not the original authors.

My approach helps users who prefer to enter long with or without the equal sign. That is, it should have same response to "--loglevel 9" as "--loglevel=9". In the --/space method, it is not possible to know for sure if the user forgets an argument, so some guessing is needed.

1. if the user has the long/equal sign format (--opt=), then a space after = triggers an error because an argument was not supplied.
2. if user has long/space arguments (--opt ), this script causes a fail if no argument follows (end of command) or if argument begins with dash)

In case you are starting out on this, there is an interesting difference between "--opt=value" and "--opt value" formats. With the equal sign, the command line argument is seen as "opt=value" and the work to handle that is string parsing, to separate at the "=". In contrast, with "--opt value", the name of the argument is "opt" and we have the challenge of getting the next value supplied in the command line. That's where @Arvid Requate used ${!OPTIND}, the indirect reference. I still don't understand that, well, at all, and comments in BashFAQ seem to warn against that style (http://mywiki.wooledge.org/BashFAQ/006). BTW, I don't think previous poster's comments about importance of OPTIND=$(( $OPTIND + 1 )) are correct. I mean to say, I see no harm from omitting it.

In newest version of this script, flag -v means VERBOSE printout.

Save it in a file called "cli-5.sh", make executable, and any of these will work, or fail in the desired way

./cli-5.sh  -v --loglevel=44 --toc  TRUE
./cli-5.sh  -v --loglevel=44 --toc=TRUE
./cli-5.sh --loglevel 7
./cli-5.sh --loglevel=8
./cli-5.sh -l9

./cli-5.sh  --toc FALSE --loglevel=77
./cli-5.sh  --toc=FALSE --loglevel=77

./cli-5.sh   -l99 -t yyy
./cli-5.sh   -l 99 -t yyy

Here is example output of the error-checking on user intpu

$ ./cli-5.sh  --toc --loglevel=77
ERROR: toc value must not have dash at beginning
$ ./cli-5.sh  --toc= --loglevel=77
ERROR: value for toc undefined

You should consider turning on -v, because it prints out internals of OPTIND and OPTARG

I've solved a similar problem with an easier solution:

import codecs
csvReader = csv.reader(codecs.open('file.csv', 'rU', 'utf-16'))

The key was using the codecs module to open the file with the UTF-16 encoding, there are a lot more of encodings, check the documentation.

System.IO.File.WriteAllText (@"D:\path.txt", contents);

• If the file exists, this overwrites it.
• If the file does not exist, this creates it.
• Please make sure you have appropriate privileges to write at the location, otherwise you will get an exception.

Using the :before pseudo-element,
CSS3's border-radius,
and some transparency is quite easy:

LIVE DEMO

<div class="circle"></div>

CSS:

.circle, .circle:before{
  position:absolute;
  border-radius:150px;  
}
.circle{  
  width:200px;
  height:200px;
  z-index:0;
  margin:11%;
  padding:40px;
  background: hsla(0, 100%, 100%, 0.6);   
}
.circle:before{
  content:'';
  display:block;
  z-index:-1;  
  width:200px;
  height:200px;

  padding:44px;
  border: 6px solid hsla(0, 100%, 100%, 0.6);
  /* 4px more padding + 6px border = 10 so... */  
  top:-10px;
  left:-10px; 
}

The :before attaches to our .circle another element which you only need to make (ok, block, absolute, etc...) transparent and play with the border opacity.

Register indicates to compiler to optimize this code by storing that particular variable in registers then in memory. it is a request to compiler, compiler may or may not consider this request. You can use this facility in case where some of your variable are being accessed very frequently. For ex: A looping.

One more thing is that if you declare a variable as register then you can't get its address as it is not stored in memory. it gets its allocation in CPU register.

You try to access private member of one class from another. The fact that bar-class is declared within foo-class means that bar in visible only inside foo class, but that is still other class.

And what is p->param?

Actually, it isn't clear what do you want to do

I highly recommend using Apache Commons (http://commons.apache.org/configuration/). It has the ability to use an XML file as a configuration file. Using an XML structure makes it easy to represent arrays as lists of values rather than specially numbered properties.

You can simply hide the <td> tag content by just including a style attribute: style = "display:none"

For e.g

<td style = "display:none" >
<p> I'm invisible </p>
</td>

>>>var=7
>>>array = [1,2,3,4,5,6]
>>>array.insert(0,var)
>>>array
[7, 1, 2, 3, 4, 5, 6]

How it works:

array.insert(index, value)

Insert an item at a given position. The first argument is the index of the element before which to insert, so array.insert(0, x) inserts at the front of the list, and array.insert(len(array), x) is equivalent to array.append(x).Negative values are treated as being relative to the end of the array.

Your question is hard to understand, but if I'm getting the gist, you simply have some value in your main view that you want to access in a partial being rendered in that view.

If you just render a partial with just the partial name:

@Html.Partial("_SomePartial")

It will actually pass your model as an implicit parameter, the same as if you were to call:

@Html.Partial("_SomePartial", Model)

Now, in order for your partial to actually be able to use this, though, it too needs to have a defined model, for example:

@model Namespace.To.Your.Model

@Html.Action("MemberProfile", "Member", new { id = Model.Id })

Alternatively, if you're dealing with a value that's not on your view's model (it's in the ViewBag or a value generated in the view itself somehow, then you can pass a ViewDataDictionary

@Html.Partial("_SomePartial", new ViewDataDictionary { { "id", someInteger } });

And then:

@Html.Action("MemberProfile", "Member", new { id = ViewData["id"] })

As with the model, Razor will implicitly pass your partial the view's ViewData by default, so if you had ViewBag.Id in your view, then you can reference the same thing in your partial.

$(JSON.parse(response)).map(function () {
    return $('<option>').val(this.value).text(this.label);
}).appendTo('#selectorId');

After calling GroupBy, you get a series of groups IEnumerable<Grouping>, where each Grouping itself exposes the Key used to create the group and also is an IEnumerable<T> of whatever items are in your original data set. You just have to call Count() on that Grouping to get the subtotal.

foreach(var line in data.GroupBy(info => info.metric)
                        .Select(group => new { 
                             Metric = group.Key, 
                             Count = group.Count() 
                        })
                        .OrderBy(x => x.Metric))
{
     Console.WriteLine("{0} {1}", line.Metric, line.Count);
}

I'm assuming you already have a list/array of some class that looks like

class UserInfo {
    string name;
    int metric;
    ..etc..
} 
...
List<UserInfo> data = ..... ;

When you do data.GroupBy(x => x.metric), it means "for each element x in the IEnumerable defined by data, calculate it's .metric, then group all the elements with the same metric into a Grouping and return an IEnumerable of all the resulting groups. Given your example data set of

    <DATA>           | Grouping Key (x=>x.metric) |
joe  1 01/01/2011 5  | 1
jane 0 01/02/2011 9  | 0
john 2 01/03/2011 0  | 2
jim  3 01/04/2011 1  | 3
jean 1 01/05/2011 3  | 1
jill 2 01/06/2011 5  | 2
jeb  0 01/07/2011 3  | 0
jenn 0 01/08/2011 7  | 0

it would result in the following result after the groupby:

(Group 1): [joe  1 01/01/2011 5, jean 1 01/05/2011 3]
(Group 0): [jane 0 01/02/2011 9, jeb  0 01/07/2011 3, jenn 0 01/08/2011 7]
(Group 2): [john 2 01/03/2011 0, jill 2 01/06/2011 5]
(Group 3): [jim  3 01/04/2011 1]

In the same idea of Nick Riggs but I create a constructor, and a push a new object in the array by using it. It avoid the repetition of the keys of the class:

var arr = [];
var columnDefs = function(key, sortable, resizeable){
    this.key = key; 
    this.sortable = sortable; 
    this.resizeable = resizeable;
    };

for (var i = 0; i < len; i++) {
    arr.push((new columnDefs(oFullResponse.results[i].label,true,true)));
}

My version handles both ASP.NET or LAN IPs:

/** 
 * Get visitor's ip address.
 */
public static string GetVisitorIp() {
    string ip = null;
    if (HttpContext.Current != null) { // ASP.NET
        ip = string.IsNullOrEmpty(HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"])
            ? HttpContext.Current.Request.UserHostAddress
            : HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
    }
    if (string.IsNullOrEmpty(ip) || ip.Trim() == "::1") { // still can't decide or is LAN
        var lan = Dns.GetHostEntry(Dns.GetHostName()).AddressList.FirstOrDefault(r => r.AddressFamily == AddressFamily.InterNetwork);
        ip = lan == null ? string.Empty : lan.ToString();
    }
    return ip;
}

Open a command prompt as admin and run this command:

bcdedit /set {current} hypervisorlaunchtype off

After a reboot, Hyper-V is still installed but the Hypervisor is no longer running. Now you can use VMware without any issues.

If you need Hyper-V again, open a command prompt as admin and run this command:

bcdedit /set {current} hypervisorlaunchtype auto

like this:

/\<word\>

\< means beginning of a word, and \> means the end of a word,

Adding @Roe's comment:
VIM provides a shortcut for this. If you already have word on screen and you want to find other instances of it, you can put the cursor on the word and press '*' to search forward in the file or '#' to search backwards.

It's about 2.1 * 10^9. No need to know the exact 2^{31} - 1 = 2,147,483,647.

C

You can find it in C like that:

#include <stdio.h>
#include <limits.h>

main() {
    printf("max int:\t\t%i\n", INT_MAX);
    printf("max unsigned int:\t%u\n", UINT_MAX);
}

gives (well, without the ,)

max int:          2,147,483,647
max unsigned int: 4,294,967,295

C++ 11

std::cout << std::numeric_limits<int>::max() << "\n";
std::cout << std::numeric_limits<unsigned int>::max() << "\n";

Java

You can get this with Java, too:

System.out.println(Integer.MAX_VALUE);

But keep in mind that Java integers are always signed.

Python 2

Python has arbitrary precision integers. But in Python 2, they are mapped to C integers. So you can do this:

import sys
sys.maxint
>>> 2147483647
sys.maxint + 1
>>> 2147483648L

So Python switches to long when the integer gets bigger than 2^31 -1

For cases where your images happen to be the same size (which is a common case for displaying image processing results), you can use numpy's concatenate to simplify your code.

To stack vertically (img1 over img2):

vis = np.concatenate((img1, img2), axis=0)

To stack horizontally (img1 to the left of img2):

vis = np.concatenate((img1, img2), axis=1)

To verify:

import cv2
import numpy as np
img1 = cv2.imread('img1.png')
img2 = cv2.imread('img2.png')
vis = np.concatenate((img1, img2), axis=1)
cv2.imwrite('out.png', vis)

The out.png image will contain img1 on the left and img2 on the right.

In full generality, this functionality is impossible. The Java ClassLoader mechanism guarantees only the ability to ask for a class with a specific name (including pacakge), and the ClassLoader can supply a class, or it can state that it does not know that class.

Classes can be (and frequently are) loaded from remote servers, and they can even be constructed on the fly; it is not difficult at all to write a ClassLoader that returns a valid class that implements a given interface for any name you ask from it; a List of the classes that implement that interface would then be infinite in length.

In practice, the most common case is an URLClassLoader that looks for classes in a list of filesystem directories and JAR files. So what you need is to get the URLClassLoader, then iterate through those directories and archives, and for each class file you find in them, request the corresponding Class object and look through the return of its getInterfaces() method.

As @Ming mentioned:

pip install -r file.txt

Here's a simple line to force update all dependencies:

while read -r package; do pip install --upgrade --force-reinstall $package;done < pipfreeze.txt

You can use the following Instagram API Endpoint to get a list of people a user is following.

https://api.instagram.com/v1/users/{user-id}/follows?access_token=ACCESS-TOKEN

Here's the complete documentation for that endpoint. GET /users/user-id/follows

And here's a sample response from executing that endpoint.

Since this endpoint required a user-id (and not user-name), depending on how you've written your API client, you might have to make a call to the /users/search endpoint with a username, and then get the user-id from the response and pass it on to the above /users/user-id/follows endpoint to get the list of followers.

IANAL, but considering it's documented in their API, and looking at the terms of use, I don't see how this wouldn't be legal to do.

Sys.Application.add_load(LoadHandler); //This load handler solved update panel did not bind control after partial postback
function LoadHandler() {
        $(document).ready(function () {
        //rebind any events here for controls under update panel
        });
}

After experiencing issues with sites breaking on Edge when using High Contrast Mode, I came across the following work by Jeff Clayton:

https://browserstrangeness.github.io/css_hacks.html

It's a crazy, weird media query, but those are easier to use in Sass:

@media screen and (min-width:0\0) and (min-resolution:+72dpi), \0screen\,screen\9 {
   .selector { rule: value };
}

This targets IE versions expect for IE8.

Or you can use:

@media screen\0 {
  .selector { rule: value };
}

Which targets IE8-11, but also triggers FireFox 1.x (which for my use case, doesn't matter).

Right now I'm testing with print support, and this seems to be working okay:

@media all\0 {
  .selector { rule: value };
}

That is not an nginx configuration file. It is part of an nginx configuration file.

The nginx configuration file (usually called nginx.conf) will look like:

events {
    ...
}
http {
    ...
    server {
        ...
    }
}

The server block is enclosed within an http block.

Often the configuration is distributed across multiple files, by using the include directives to pull in additional fragments (for example from the sites-enabled directory).

Use sudo nginx -t to test the complete configuration file, which starts at nginx.conf and pulls in additional fragments using the include directive. See this document for more.

Simply put the following one. This works for me.

$('.className').datepicker('setDate', 'now');

The bottom statement is equivalent to:

.half {
   flex-grow: 0;
   flex-shrink: 0;
   flex-basis: 50%;
}

Which, in this case, would be equivalent as the box is not allowed to flex and therefore retains the initial width set by flex-basis.

Flex-basis defines the default size of an element before the remaining space is distributed so if the element were allowed to flex (grow/shrink) it may not be 50% of the width of the page.

I've found that I regularly return to https://css-tricks.com/snippets/css/a-guide-to-flexbox/ for help regarding flexbox :)

u forgot to add proper content-type header in the response which is a must have http header when hosting on apache2

use

print "Content-type:text/html\r\n\r\n"

or

header('Content-Type: text/html');

Another possible cause of this error is a mismatched workgroup file. That is, if you try to use a secured (or partially-secured) MDB with a workgroup file other than the one used to secure it, you can trigger the error (I've seen it myself, years ago with Access 2000).

If you want to pass in the value to use, you have to use the enum type you declared and directly use the supplied value:

public string CreateFile(string id, string name, string description,
              /* --> */  SupportedPermissions supportedPermissions)
{
    file = new File
    {  
        Name = name,
        Id = id,
        Description = description,
        SupportedPermissions = supportedPermissions // <---
    };

    return file.Id;
}

If you instead want to use a fixed value, you don't need any parameter at all. Instead, directly use the enum value. The syntax is similar to a static member of a class:

public string CreateFile(string id, string name, string description) // <---
{
    file = new File
    {  
        Name = name,
        Id = id,
        Description = description,
        SupportedPermissions = SupportedPermissions.basic // <---
    };

    return file.Id;
}

It sounds like you want something like this:

$numItems = count($arr);
$i = 0;
foreach($arr as $key=>$value) {
  if(++$i === $numItems) {
    echo "last index!";
  }
}    

That being said, you don't -have- to iterate over an "array" using foreach in php.

The Alert Method, authenticateUsing() lets you skip the Http Basic Authentication box.

WebDriverWait wait = new WebDriverWait(driver, 10);      
Alert alert = wait.until(ExpectedConditions.alertIsPresent());     
alert.authenticateUsing(new UserAndPassword(username, password));

As of Selenium 3.4 it is still in beta

Right now implementation is only done for InternetExplorerDriver

In Place of using this

MsgBox(json.SelectToken("Venue").SelectToken("ID"))

You can also use

MsgBox(json.SelectToken("Venue.ID"))

I needed to have a button handler that created a form post to another application within the client's browser. I landed on this question but didn't see an answer that suited my scenario. This is what I came up with:

      protected void Button1_Click(object sender, EventArgs e)
        {

            var formPostText = @"<html><body><div>
<form method=""POST"" action=""OtherLogin.aspx"" name=""frm2Post"">
  <input type=""hidden"" name=""field1"" value=""" + TextBox1.Text + @""" /> 
  <input type=""hidden"" name=""field2"" value=""" + TextBox2.Text + @""" /> 
</form></div><script type=""text/javascript"">document.frm2Post.submit();</script></body></html>
";
            Response.Write(formPostText);
        }

The headers only remain fixed when the UITableViewStyle property of the table is set to UITableViewStylePlain. If you have it set to UITableViewStyleGrouped, the headers will scroll up with the cells.

You can use Date.before() or Date.after() or Date.equals() for date comparison.

        compareDates("2017-01-13 00:00:00", "2017-01-13 00:00:00");//output will be Date1 is equal Date2 because both date and time are equal
    }

    public static void compareDates(String d1,String d2)
    {
        try{
            // If you already have date objects then skip 1

            //1
            // Create 2 dates starts
            SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
            Date date1 = sdf.parse(d1);
            Date date2 = sdf.parse(d2);

            System.out.println("Date1"+sdf.format(date1));
            System.out.println("Date2"+sdf.format(date2));System.out.println();

            }

            //equals() returns true if both the dates are equal
            if(date1.equals(date2)){
                System.out.println("Date1 is equal Date2");
            }

            System.out.println();
        }
        catch(ParseException ex){
            ex.printStackTrace();

On Boostrap 4 simply add mx-auto to your carousel image class.

<div class="carousel-item">
  <img class="d-block mx-auto" src="http://placehold.it/600x400" />
</div> 

Combine with the samples from the bootstrap carousel documentation as desired.

As Praveen mentions above, when using the basic FileInputFormat classes is just the number of input splits that constitute the data. The number of reducers is controlled by mapred.reduce.tasks specified in the way you have it: -D mapred.reduce.tasks=10 would specify 10 reducers. Note that the space after -D is required; if you omit the space, the configuration property is passed along to the relevant JVM, not to Hadoop.

Are you specifying 0 because there is no reduce work to do? In that case, if you're having trouble with the run-time parameter, you can also set the value directly in code. Given a JobConf instance job, call

job.setNumReduceTasks(0);

inside, say, your implementation of Tool.run. That should produce output directly from the mappers. If your job actually produces no output whatsoever (because you're using the framework just for side-effects like network calls or image processing, or if the results are entirely accounted for in Counter values), you can disable output by also calling

job.setOutputFormat(NullOutputFormat.class);

One thing to note is that ngModel is required for ngOptions to work... note the ng-model="blah" which is saying "set $scope.blah to the selected value".

Try this:

<select ng-model="blah" ng-options="item.ID as item.Title for item in items"></select>

Here's more from AngularJS's documentation (if you haven't seen it):

for array data sources:

• label for value in array
• select as label for value in array
• label group by group for value in array = select as label group by group for value in array

for object data sources:

• label for (key , value) in object
• select as label for (key , value) in object
• label group by group for (key, value) in object
• select as label group by group for (key, value) in object

For some clarification on option tag values in AngularJS:

When you use ng-options, the values of option tags written out by ng-options will always be the index of the array item the option tag relates to. This is because AngularJS actually allows you to select entire objects with select controls, and not just primitive types. For example:

app.controller('MainCtrl', function($scope) {
   $scope.items = [
     { id: 1, name: 'foo' },
     { id: 2, name: 'bar' },
     { id: 3, name: 'blah' }
   ];
});

<div ng-controller="MainCtrl">
   <select ng-model="selectedItem" ng-options="item as item.name for item in items"></select>
   <pre>{{selectedItem | json}}</pre>
</div>

The above will allow you to select an entire object into $scope.selectedItem directly. The point is, with AngularJS, you don't need to worry about what's in your option tag. Let AngularJS handle that; you should only care about what's in your model in your scope.

Here is a plunker demonstrating the behavior above, and showing the HTML written out

Dealing with the default option:

There are a few things I've failed to mention above relating to the default option.

Selecting the first option and removing the empty option:

You can do this by adding a simple ng-init that sets the model (from ng-model) to the first element in the items your repeating in ng-options:

<select ng-init="foo = foo || items[0]" ng-model="foo" ng-options="item as item.name for item in items"></select>

Note: This could get a little crazy if foo happens to be initialized properly to something "falsy". In that case, you'll want to handle the initialization of foo in your controller, most likely.

Customizing the default option:

This is a little different; here all you need to do is add an option tag as a child of your select, with an empty value attribute, then customize its inner text:

<select ng-model="foo" ng-options="item as item.name for item in items">
   <option value="">Nothing selected</option>
</select>

Note: In this case the "empty" option will stay there even after you select a different option. This isn't the case for the default behavior of selects under AngularJS.

A customized default option that hides after a selection is made:

If you wanted your customized default option to go away after you select a value, you can add an ng-hide attribute to your default option:

<select ng-model="foo" ng-options="item as item.name for item in items">
   <option value="" ng-if="foo">Select something to remove me.</option>
</select>

I am sure there is ANT tags to do it but have used this 7zip hack in .bat script. I use http://www.7-zip.org/ command line tool. All the times I use this for changing jdbc url within j2ee context.xml file.

mkdir .\temp-install
c:\apps\commands\7za.exe x -y mywebapp.war META-INF/context.xml -otemp-install\mywebapp
..here I have small tool to replace text in xml file..
c:\apps\commands\7za.exe u -y -tzip mywebapp.war ./temp-install/mywebapp/*
rmdir /Q /S .\temp-install

You could extract entire .war file (its zip after all), delete files, replace files, add files, modify files and repackage to .war archive file. But changing one file in a large .war archive this might be best extracting specific file and then update original archive.

Ross, you can use Arrays.copyof() or Arrays.copyOfRange() too.

Integer[] integerArray = Arrays.copyOf(a, a.length, Integer[].class);
Integer[] integerArray = Arrays.copyOfRange(a, 0, a.length, Integer[].class);

Here the reason to hitting an ClassCastException is you can't treat an array of Integer as an array of Object. Integer[] is a subtype of Object[] but Object[] is not a Integer[].

And the following also will not give an ClassCastException.

Object[] a = new Integer[1];
Integer b=1;
a[0]=b;
Integer[] c = (Integer[]) a;

When docker kill CONTAINER_ID does not work and docker stop -t 1 CONTAINER_ID also does not work, you can try to delete the container:

docker container rm CONTAINER_ID

I had a similar issue today where containers were in a continuous restart loop.

The issue in my case was related to me being a poor engineer.

Anyway, I fixed the issue by deleting the container, fixing my code, and then rebuilding and running the container.

Hope that this helps anyone stuck with this issue in future

Maybe .text instead of .html?

this will be slow, but if it is a one time thing, try...

select * from parameters where name like '%'+char(13)+'%' or name like '%'+char(10)+'%'

Note that the ANSI SQL string concatenation operator is "||", so it may need to be:

select * from parameters where name like '%' || char(13) || '%' or name like '%' || char(10) || '%'

$(':input').bind('click keyup', function(){
    // do stuff
});

Demo: http://jsfiddle.net/X8cV3/

A different approach to the problem:

struct A {
    static const map<int, string> * singleton_map() {
        static map<int, string>* m = NULL;
        if (!m) {
            m = new map<int, string>;
            m[42] = "42"
            // ... other initializations
        }
        return m;
    }

    // rest of the class
}

This is more efficient, as there is no one-type copy from stack to heap (including constructor, destructors on all elements). Whether this matters or not depends on your use case. Does not matter with strings! (but you may or may not find this version "cleaner")

$.each(JSON.parse(result), function(i, item) {
    alert(item.number);
});

Here you go: http://mochajs.org/#test-level

it('accesses the network', function(done){
  this.timeout(500);
  [Put network code here, with done() in the callback]
})

For arrow function use as follows:

it('accesses the network', (done) => {
  [Put network code here, with done() in the callback]
}).timeout(500);

You need to load the URL Helper in order to use base_url(). In your controller, do:

$this->load->helper('url');

Then in your view you can do:

echo base_url();

I wanted a function that would join tables without requiring you to define the columns using an anonymous type selector, but had a hard time finding any. I ended up having to make my own. Hopefully this will help anyone in the future who searches for this:

private DataTable JoinDataTables(DataTable t1, DataTable t2, params Func<DataRow, DataRow, bool>[] joinOn)
{
    DataTable result = new DataTable();
    foreach (DataColumn col in t1.Columns)
    {
        if (result.Columns[col.ColumnName] == null)
            result.Columns.Add(col.ColumnName, col.DataType);
    }
    foreach (DataColumn col in t2.Columns)
    {
        if (result.Columns[col.ColumnName] == null)
            result.Columns.Add(col.ColumnName, col.DataType);
    }
    foreach (DataRow row1 in t1.Rows)
    {
        var joinRows = t2.AsEnumerable().Where(row2 =>
            {
                foreach (var parameter in joinOn)
                {
                    if (!parameter(row1, row2)) return false;
                }
                return true;
            });
        foreach (DataRow fromRow in joinRows)
        {
            DataRow insertRow = result.NewRow();
            foreach (DataColumn col1 in t1.Columns)
            {
                insertRow[col1.ColumnName] = row1[col1.ColumnName];
            }
            foreach (DataColumn col2 in t2.Columns)
            {
                insertRow[col2.ColumnName] = fromRow[col2.ColumnName];
            }
            result.Rows.Add(insertRow);
        }
    }
    return result;
}

An example of how you might use this:

var test = JoinDataTables(transactionInfo, transactionItems,
               (row1, row2) =>
               row1.Field<int>("TransactionID") == row2.Field<int>("TransactionID"));

One caveat: This is certainly not optimized, so be mindful when getting to row counts above 20k. If you know that one table will be larger than the other, try to put the smaller one first and the larger one second.

Override toString() method in Student class as below:

   @Override
   public String toString() {
        return ("StudentName:"+this.getStudentName()+
                    " Student No: "+ this.getStudentNo() +
                    " Email: "+ this.getEmail() +
                    " Year : " + this.getYear());
   }

If the table you are deleting from has BEFORE/AFTER DELETE triggers, something in there could be causing your delay.

Additionally, if you have foreign keys referencing that table, additional UPDATEs or DELETEs may be occurring.

I was having trouble with react-native-navigation, I created my own header component, then inserted a image - as logo - on the left before title, then when I was triggering navigate to another screen and then back again, logo was loading again, with a timeout near 1s, my file were local. My solution :

Logo.json

{"file" : "base64 big string"}

App.js

import Logo from '.../Logo.json'
...
<Image source:{{uri:Logo.file}} />

if you are using mysql .. you can save date as "2009-12-31" for example.

update person set birthday_date = '2009-12-31'

but i prefer to use jdbc although you have to create java.sql.Date ...

*Date is kind of evil in this world ... :)

The two pieces of code are really doing two different things. The first version will pull members as you need them. The second version will load all the results into memory before you start to do anything with it.

There's no right or wrong answer to this one. Which one is preferable just depends on the situation. For example, if there's a limit of time that you have to complete your query and you need to do something semi-complicated with the results, the second version could be preferable. But beware large resultsets, especially if you're running this code in 32-bit mode. I've been bitten by OutOfMemory exceptions several times when doing this method.

The key thing to keep in mind is this though: the differences are in efficiency. Thus, you should probably go with whichever one makes your code simpler and change it only after profiling.

? public makes it accessible across the other classes. You can use it without instantiate of the class or using any object.

? static makes it uniform value across all the class instances. It ensures that you don't waste memory creating many of the same thing if it will be the same value for all the objects.

? final makes it non-modifiable value. It's a "constant" value which is same across all the class instances and cannot be modified.

I think your only option is to wrap java in a script that substitutes the environment variables into the command line

In your layout you can add android:checked="true" to CheckBox you want to be selected.

Or programmatically, you can use the setChecked method defined in the checkable interface:

RadioButton b = (RadioButton) findViewById(R.id.option1); b.setChecked(true);

Are you certain that the table in question exists?

Have you refreshed the table view in the Object Explorer? This can be done by right clicking the "tables" folder and pressing the F5 key.

You may also need to reresh the Intellisense cache.

This can be done by following the menu route: Edit -> IntelliSense -> Refresh Local Cache

Let's benchmark the three solutions proposed:

# use rbind
f1 <- function(n){
  df <- data.frame(x = numeric(), y = character())
  for(i in 1:n){
    df <- rbind(df, data.frame(x = i, y = toString(i)))
  }
  df
}
# use list
f2 <- function(n){
  df <- data.frame(x = numeric(), y = character(), stringsAsFactors = FALSE)
  for(i in 1:n){
    df[i,] <- list(i, toString(i))
  }
  df
}
# pre-allocate space
f3 <- function(n){
  df <- data.frame(x = numeric(1000), y = character(1000), stringsAsFactors = FALSE)
  for(i in 1:n){
    df$x[i] <- i
    df$y[i] <- toString(i)
  }
  df
}
system.time(f1(1000))
#   user  system elapsed 
#   1.33    0.00    1.32 
system.time(f2(1000))
#   user  system elapsed 
#   0.19    0.00    0.19 
system.time(f3(1000))
#   user  system elapsed 
#   0.14    0.00    0.14

The best solution is to pre-allocate space (as intended in R). The next-best solution is to use list, and the worst solution (at least based on these timing results) appears to be rbind.

Can also try.

 _lstProductDetail.Where(S => S.ProductID == "")
        .Select(S => { S.ProductPcs = "Update Value" ; return S; }).ToList();

That can be done much simpler considering that int(True) is 1 and int(False) is 0:

from datetime import date

def calculate_age(born):
    today = date.today()
    return today.year - born.year - ((today.month, today.day) < (born.month, born.day))

jQuery $(window).height(); or $(window).width(); is only work perfectly when your html page doctype is html

<!DOCTYPE html>
<html lang="en">
...

'''the only simple method to understand the logic use for loop'''

Lap=[2,5,7,7,9] x=1 for i in Lap: x=i*x print(x)

After testing it with RSpec like this:

describe Hash do
  describe :map_values do
    it 'should map the values' do
      expect({:a => 2, :b => 3}.map_values { |x| x ** 2 }).to eq({:a => 4, :b => 9})
    end
  end
end

You could implement Hash#map_values as follows:

class Hash
  def map_values
    Hash[map { |k, v| [k, yield(v)] }]
  end
end

The function then can be used like this:

{:a=>'a' , :b=>'b'}.map_values { |v| "%#{v}%" }
# {:a=>"%a%", :b=>"%b%"}

The reason your CSS isn't working is because of specificity. The Bootstrap selector has a higher specificity than yours, so your style is completely ignored.

Bootstrap styles this with the selector: .navbar-default .navbar-toggle .icon-bar. This selector has a B specificity value of 3, whereas yours only has a B specificity value of 1.

Therefore, to override this, simply use the same selector in your CSS (assuming your CSS is included after Bootstrap's):

.navbar-default .navbar-toggle .icon-bar {
    background-color: black;
}

We can add drawable .xml like below

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle">


    <stroke
        android:width="1dp"
        android:color="@color/color_C4CDD5"/>

    <corners android:radius="8dp"/>

    <solid
        android:color="@color/color_white"/>

</shape>

@BrenBarn's answer says it all, but if you're like me it might take a while to understand. Here's my case and how @BrenBarn's answer applies to it, perhaps it will help you.

The case

package/
    __init__.py
    subpackage1/
        __init__.py
        moduleX.py
    moduleA.py

Using our familiar example, and add to it that moduleX.py has a relative import to ..moduleA. Given that I tried writing a test script in the subpackage1 directory that imported moduleX, but then got the dreaded error described by the OP.

Solution

Move test script to the same level as package and import package.subpackage1.moduleX

Explanation

As explained, relative imports are made relative to the current name. When my test script imports moduleX from the same directory, then module name inside moduleX is moduleX. When it encounters a relative import the interpreter can't back up the package hierarchy because it's already at the top

When I import moduleX from above, then name inside moduleX is package.subpackage1.moduleX and the relative import can be found

Make sure you have Data Source and not DataSource in your connection string. The space is important. Trust me. I'm an idiot.

As other said, bubbling and capturing describe in which order some nested elements receive a given event.

I wanted to point out that for the innermost element may appear something strange. Indeed, in this case the order in which the event listeners are added does matter.

In the following example, capturing for div2 will be executed first than bubbling; while bubbling for div4 will be executed first than capturing.

function addClickListener (msg, num, type) {
  document.querySelector("#div" + num)
    .addEventListener("click", () => alert(msg + num), type);
}
bubble  = (num) => addClickListener("bubble ", num, false);
capture = (num) => addClickListener("capture ", num, true);

// first capture then bubble
capture(1);
capture(2);
bubble(2);
bubble(1);

// try reverse order
bubble(3);
bubble(4);
capture(4);
capture(3);

#div1, #div2, #div3, #div4 {
  border: solid 1px;
  padding: 3px;
  margin: 3px;
}

<div id="div1">
  div 1
  <div id="div2">
    div 2
  </div>
</div>
<div id="div3">
  div 3
  <div id="div4">
    div 4
  </div>
</div>

I created a simplified version using Array.prototype.includes(). My technique is similar to @Kunle Babatunde.

const isVowel = (char) => ["a", "e", "i", "o", "u"].includes(char);_x000D_
_x000D_
console.log(isVowel("o"), isVowel("s"));

Try this code.You can replace any character with another given character. Here I tried to replace the letter 'a' with "-" character for the give string "abcdeaa"

OutPut -->_bcdef__

    public class Replace {

    public static void replaceChar(String str,String target){
        String result = str.replaceAll(target, "_");
        System.out.println(result);
    }

    public static void main(String[] args) {
        replaceChar("abcdefaa","a");
    }

}

When using SQLFiddle, make sure that the separator is set to GO. Also the schema build script is executed in a different connection from the run script, so a temp table created in the one is not visible in the other. This fiddle shows that your code is valid and working in SQL 2012:

SQL Fiddle

MS SQL Server 2012 Schema Setup:

Query 1:

CREATE TABLE #Names
  ( 
    Name1 VARCHAR(100),
    Name2 VARCHAR(100)
  ) 

INSERT INTO #Names
  (Name1, Name2)
VALUES
  ('Matt', 'Matthew'),
  ('Matt', 'Marshal'),
  ('Matt', 'Mattison')

SELECT * FROM #NAMES

Results:

| NAME1 |    NAME2 |
--------------------
|  Matt |  Matthew |
|  Matt |  Marshal |
|  Matt | Mattison |

Here a SSMS 2012 screenshot:

In perl:

if($testString =~ /\d/) 
{
    print "This string contains at least one digit"
}

where \d matches to a digit.

If you backup a table in Oracle Database. You try the statement below.

CREATE TABLE name_table_bk
AS
SELECT *
  FROM name_table;

I am using Oracle Database 12c.

Try:

insert into account_type_standard (account_type_Standard_id, tax_status_id, recipient_id)
select account_type_standard_seq.nextval,
       ts.tax_status_id, 
       ( select r.recipient_id
         from recipient r
         where r.recipient_code = ?
       )
from tax_status ts
where ts.tax_status_code = ?

This is some different method to do the same thing:

$(document).ready(function (){_x000D_
_x000D_
    $('#isAgeSelected').click(function() {_x000D_
        // $("#txtAge").toggle(this.checked);_x000D_
_x000D_
        // Using a pure CSS selector_x000D_
        if ($(this.checked)) {_x000D_
            alert('on check 1');_x000D_
        };_x000D_
_x000D_
        // Using jQuery's is() method_x000D_
        if ($(this).is(':checked')) {_x000D_
            alert('on checked 2');_x000D_
        };_x000D_
_x000D_
        //  // Using jQuery's filter() method_x000D_
        if ($(this).filter(':checked')) {_x000D_
            alert('on checked 3');_x000D_
        };_x000D_
    });_x000D_
});

<script src="http://code.jquery.com/jquery-1.9.1.js"></script>_x000D_
<input type="checkbox" id="isAgeSelected"/>_x000D_
<div id="txtAge" style="display:none">Age is something</div>

The first value is the precision and the second is the scale, so 18,0 is essentially 18 digits with 0 digits after the decimal place. If you had 18,2 for example, you would have 18 digits, two of which would come after the decimal...

example of 18,2: 1234567890123456.12

There is no functional difference between numeric and decimal, other that the name and I think I recall that numeric came first, as in an earlier version.

And to answer, "can I add (-10) in that column?" - Yes, you can.

some people talk very well about PyInstaller

http://www.pyinstaller.org/

In case you need to check each of the Employee object whether it is a Manager object, use the OfType method:

List<Employee> employees = new List<Employee>();

//Code to add some Employee or Manager objects..

var onlyManagers = employees.OfType<Manager>();

foreach (Manager m in onlyManagers) {
  // Do Manager specific thing..
}

Just make changes on AppRoutingModule like

@NgModule({
imports: [RouterModule.forRoot(routes, { scrollPositionRestoration: 'enabled' })],
  exports: [RouterModule]
})

A Java ClassCastException is an Exception that can occur when you try to improperly convert a class from one type to another.

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

public class ClassCastExceptionExample {

  public ClassCastExceptionExample() {

    List list = new ArrayList();
    list.add("one");
    list.add("two");
    Iterator it = list.iterator();
    while (it.hasNext()) {
        // intentionally throw a ClassCastException by trying to cast a String to an
        // Integer (technically this is casting an Object to an Integer, where the Object 
        // is really a reference to a String:
        Integer i = (Integer)it.next();
    }
  }
 public static void main(String[] args) {
  new ClassCastExceptionExample();
 }
}

If you try to run this Java program you’ll see that it will throw the following ClassCastException:

Exception in thread "main" java.lang.ClassCastException: java.lang.String
at ClassCastExceptionExample  (ClassCastExceptionExample.java:15)
at ClassCastExceptionExample.main  (ClassCastExceptionExample.java:19)

The reason an exception is thrown here is that when I’m creating my list object, the object I store in the list is the String “one,” but then later when I try to get this object out I intentionally make a mistake by trying to cast it to an Integer. Because a String cannot be directly cast to an Integer — an Integer is not a type of String — a ClassCastException is thrown.

From, Programming Recommendations, PEP 8:

Comparisons to singletons like None should always be done with is or is not, never the equality operators.

Also, beware of writing if x when you really mean if x is not None — e.g. when testing whether a variable or argument that defaults to None was set to some other value. The other value might have a type (such as a container) that could be false in a boolean context!

PEP 8 is essential reading for any Python programmer.

 var geturl;
  geturl = $.ajax({
    type: "GET",
    url: 'http://....',
    success: function () {
      alert("done!"+ geturl.getAllResponseHeaders());
    }
  });

Besides convenience in insertions and deletions, the memory representation of linked list is different than the arrays. There is no restriction on the number of elements in a linked list, while in the arrays, you have to specify the total number of elements. Check this article.

I got here because I wanted to create a range between -10 and 10 in increments of 0.1 using list comprehension. Instead of doing an overly complicated function like most of the answers above I just did this

simple_range = [ x*0.1 for x in range(-100, 100) ]

By changing the range count to 100 I now get my range of -10 through 10 by using the standard range function. So if you need it by 0.2 then just do range(-200, 200) and so on etc

I wrote an add-on to overcome this issue in Firefox (Chrome, Opera version will have soon). It works with the latest Firefox version, with beautiful UI and support JS regex: https://addons.mozilla.org/en-US/firefox/addon/cross-domain-cors

This is the approach I've used. It's quite straightforward, and works just fine.

In the CK editor root directory there is a file named config.js

I added this (you don't need the querystring stuff, this is just for our file manager). I also included some skinning and changing of the default buttons shown:

CKEDITOR.editorConfig = function(config) {

    config.skin = 'v2';
    config.startupFocus = false;
    config.filebrowserBrowseUrl = '/admin/content/filemanager.aspx?path=Userfiles/File&editor=FCK';
    config.filebrowserImageBrowseUrl = '/admin/content/filemanager.aspx?type=Image&path=Userfiles/Image&editor=FCK';
    config.toolbar_Full =
    [
        ['Source', '-', 'Preview', '-'],
        ['Cut', 'Copy', 'Paste', 'PasteText', 'PasteFromWord', '-', 'Print', 'SpellChecker'], //, 'Scayt' 
        ['Undo', 'Redo', '-', 'Find', 'Replace', '-', 'SelectAll', 'RemoveFormat'],
        '/',
        ['Bold', 'Italic', 'Underline', 'Strike', '-', 'Subscript', 'Superscript'],
        ['NumberedList', 'BulletedList', '-', 'Outdent', 'Indent', 'Blockquote'],
        ['JustifyLeft', 'JustifyCenter', 'JustifyRight', 'JustifyBlock'],
        ['Link', 'Unlink', 'Anchor'],
        ['Image', 'Flash', 'Table', 'HorizontalRule', 'SpecialChar'],
        '/',
        ['Styles', 'Format', 'Templates'],
        ['Maximize', 'ShowBlocks']
    ];

};

Then, our file manager calls this:

opener.SetUrl('somefilename');

The best way to make the header full screen is set height to be 100vh

#header{
height: 100vh;
}

I have faced the same problem and I have fixed. Please make sure some things as written bellow :

   Mail::send('emails.auth.activate', array('link'=> URL::route('account-activate', $code),'username'=>$user->username),function($message) use ($user) {
                        $message->to($user->email , $user->username)->subject('Active your account !');

                    });

This should be your emails.activation

    Hello {{ $username }} , <br> <br> <br>

    We have created your account ! Awesome ! Please activate by clicking the   following link <br> <br> <br>
   ----- <br>
      {{ $link }} <br> <br> <br>
       ---- 

The answer to your why you can't call $email variable into your mail sending function. You need to call $user variable then you can write your desired variable as $user->variable

Thank You :)

The overhead of creating the new processes is minimal, especially when it's just 4 of them. I doubt this is a performance hot spot of your application. Keep it simple, optimize where you have to and where profiling results point to.

Brandon, short and sweet. Also flexible.

Hope this helps.

I would add some checks after the copy (using '||') but i'm not sure how "copy /v" reacts when it encounters an error.

you may want to try this:

copy /V "%%f" "%dTarget%\" 2>nul|| echo En error occured copying "%%F".&& exit /b 1

As the copy line. let me know if you get something out of it (in no position to test a copy failure atm..)

on the web site box, you have selected .NETFramework 4.5 and it doesn show, so click there and choose the 3.5...i hope it helps.

You don't have to necessarily provide name and Qualifier. If you set a name, that's the name with which the bean is registered in the context. If you don't provide a name for your service it will be registered as uncapitalized non-qualified class name based on BeanNameGenerator. So in your case the Implementation will be registered as employeeServiceImpl. So if you try to autowire with that name, it should resolve directly.

private EmployeeService employeeServiceImpl;

@RequestMapping("/employee")
public String employee() {
    this.employeeService.fetchAll();
    return "employee";
}

@Autowired(required = true)
public void setEmployeeService(EmployeeService employeeServiceImpl) {
    this.employeeServiceImpl = employeeServiceImpl;
}

@Qualifier is used in case if there are more than one bean exists of same type and you want to autowire different implementation beans for various purposes.

You can view the INDEXES column below where you find a default PRIMARY KEY is set. If it is not set or you want to set any other variable as a PRIMARY KEY then , there is a dialog box below to create an index which asks for a column number ,either way you can create a new one or edit an existing one.The existing one shows up a edit button whee you can go and edit it and you're done save it and you are ready to go

Try browser.execute_script instead of selenium.GetEval.

See this answer for example.

As discussed, there are several ways to search:

/pattern
?pattern
* (and g*, which I sometimes use in macros)
# (and g#)

plus, navigating prev/next with N and n.

You can also edit/recall your search history by pulling up the search prompt with / and then cycle with C-p/C-n. Even more useful is q/, which takes you to a window where you can navigate the search history.

Also for consideration is the all-important 'hlsearch' (type :hls to enable). This makes it much easier to find multiple instances of your pattern. You might even want make your matches extra bright with something like:

hi Search ctermfg=yellow ctermbg=red guifg=...

But then you might go crazy with constant yellow matches all over your screen. So you’ll often find yourself using :noh. This is so common that a mapping is in order:

nmap <leader>z :noh<CR>

I easily remember this one as z since I used to constantly type /zz<CR> (which is a fast-to-type uncommon occurrence) to clear my highlighting. But the :noh mapping is way better.

It has happened the same thing to me in XCode 6.3.1. I managed to fix it by:

• Going to View->Navigators->Show Debug Navigators
• Right click in the project root -> Move Breakpoints (If selected the User option)
• (I also Selected the option share breakpoints, even though I'm not sure if that necessary).

After doing that change I set the Move breakpoints options back to the project, and unselecting the Share breakpoints option, and still works.

I don't exactly know why but this get my breakpoints back.

Another option besides those above is:

df = df.groupby(df.columns, axis = 1).transform(lambda x: x.fillna(x.mean()))

It's less elegant than previous responses for mean, but it could be shorter if you desire to replace nulls by some other column function.

This is my approach to solve this problem without any extra modules. Just using the built-in fs and path modules.

Note: This does use the read / write functions of fs, so it does not copy any meta data (time of creation, etc.). As of Node.js 8.5 there is a copyFileSync function available which calls the OS copy functions and therefore also copies meta data. I did not test them yet, but it should work to just replace them. (See https://nodejs.org/api/fs.html#fs_fs_copyfilesync_src_dest_flags)

var fs = require('fs');
var path = require('path');

function copyFileSync( source, target ) {

    var targetFile = target;

    // If target is a directory, a new file with the same name will be created
    if ( fs.existsSync( target ) ) {
        if ( fs.lstatSync( target ).isDirectory() ) {
            targetFile = path.join( target, path.basename( source ) );
        }
    }

    fs.writeFileSync(targetFile, fs.readFileSync(source));
}

function copyFolderRecursiveSync( source, target ) {
    var files = [];

    // Check if folder needs to be created or integrated
    var targetFolder = path.join( target, path.basename( source ) );
    if ( !fs.existsSync( targetFolder ) ) {
        fs.mkdirSync( targetFolder );
    }

    // Copy
    if ( fs.lstatSync( source ).isDirectory() ) {
        files = fs.readdirSync( source );
        files.forEach( function ( file ) {
            var curSource = path.join( source, file );
            if ( fs.lstatSync( curSource ).isDirectory() ) {
                copyFolderRecursiveSync( curSource, targetFolder );
            } else {
                copyFileSync( curSource, targetFolder );
            }
        } );
    }
}

In a new sheet (where you want to create a new pivot table) press the key combination (Alt+D+P). In the list of data source options choose "Microsoft Excel list of database". Click Next and select the pivot table that you want to use as a source (select starting with the actual headers of the fields). I assume that this range is rather static and if you refresh the source pivot and it changes it's size you would have to re-size the range as well. Hope this helps.

In this example, nothing really. The exact param comes into play when you have multiple paths that have similar names:

For example, imagine we had a Users component that displayed a list of users. We also have a CreateUser component that is used to create users. The url for CreateUsers should be nested under Users. So our setup could look something like this:

<Switch>
  <Route path="/users" component={Users} />
  <Route path="/users/create" component={CreateUser} />
</Switch>

Now the problem here, when we go to http://app.com/users the router will go through all of our defined routes and return the FIRST match it finds. So in this case, it would find the Users route first and then return it. All good.

But, if we went to http://app.com/users/create, it would again go through all of our defined routes and return the FIRST match it finds. React router does partial matching, so /users partially matches /users/create, so it would incorrectly return the Users route again!

The exact param disables the partial matching for a route and makes sure that it only returns the route if the path is an EXACT match to the current url.

So in this case, we should add exact to our Users route so that it will only match on /users:

<Switch>
  <Route exact path="/users" component={Users} />
  <Route path="/users/create" component={CreateUser} />
</Switch>

The docs explain exact in detail and give other examples.

There is the same problem in Linux OS. The issue is related on Windows OS, but Homestead is a Ubuntu VM, and the solution posted works strongly good in others SO. I applied the commands sugested by flik, and the problems was solved. I only used the following commands

I only used the following commands

rm -rf node_modules
npm cache clear --force

After

npm install cross-env
npm install 
npm run watch

It's working fine on linux Fedora 25.

\usepackage{array} in the preamble

then this:

\begin{tabular}{| >{\centering\arraybackslash}m{1in} | >{\centering\arraybackslash}m{1in} |}

note that the "m" for fixed with column is provided by the array package, and will give you vertical centering (if you don't want this just go back to "p"

SELECT *
FROM A.tableA JOIN B.tableB 

or

SELECT *
  FROM A.tableA JOIN B.tableB
  ON A.tableA.id = B.tableB.a_id;

sudo npm install -g @angular/cli

use this. it worked for me

I know the OP is asking for a CSS-only solution. But in case anyone landing here from the Magic Google ends up requiring a JavaScript solution, here's a one-liner:

capitalize = str => str[0].toUpperCase() + str.substr(1);

e.g.:

capitalize('foo bar baz'); // -> 'Foo bar baz'

The answer by Greg Hewgill, that was edited by Johannchopin helped me, as I did not care about removing the file from the history completely. In my case, it was a directory, so the only change I did was using:

git rm -r --cached myDirectoryName

instead of "git rm --cached file1.txt" ..followed by:

git commit -m "deleted myDirectoryName from git"
git push origin branch_name

Thanks Greg Hewgill and Johannchopin!

A Swift4/Swift5 + RxSwift example (import RxGesture as well)

view.rx.tapGesture()
        .when(GestureRecognizerState.recognized)
        .subscribe({ _ in
            self.view.endEditing(true)
        })
        .disposed(by: disposeBag)

There are probably embedded tabs (CHAR(9)) etc. as well. You can find out what other characters you need to replace (we have no idea what your goal is) with something like this:

DECLARE @var NVARCHAR(255), @i INT;

SET @i = 1;

SELECT @var = AccountType FROM dbo.Account
  WHERE AccountNumber = 200
  AND AccountType LIKE '%Daily%';

CREATE TABLE #x(i INT PRIMARY KEY, c NCHAR(1), a NCHAR(1));

WHILE @i <= LEN(@var)
BEGIN
  INSERT #x 
    SELECT SUBSTRING(@var, @i, 1), ASCII(SUBSTRING(@var, @i, 1));

  SET @i = @i + 1;
END

SELECT i,c,a FROM #x ORDER BY i;

You might also consider doing better cleansing of this data before it gets into your database. Cleaning it every time you need to search or display is not the best approach.

ALTER TABLE tblcatalog
    CHANGE COLUMN id id INT(11) NOT NULL AUTO_INCREMENT FIRST;

function convertStringToCamelCase(str){
    return str.split(' ').map(function(item, index){
        return index !== 0 
            ? item.charAt(0).toUpperCase() + item.substr(1) 
            : item.charAt(0).toLowerCase() + item.substr(1);
    }).join('');
}      

If Multiset extends from the Array class

x = [1, 1, 2, 4, 7]
y = [1, 2, 2, 2]
z = [1, 1, 3, 7]

UNION

x.union(y)           # => [1, 2, 4, 7]      (ONLY IN RUBY 2.6)
x.union(y, z)        # => [1, 2, 4, 7, 3]   (ONLY IN RUBY 2.6)
x | y                # => [1, 2, 4, 7]

DIFFERENCE

x.difference(y)      # => [4, 7] (ONLY IN RUBY 2.6)
x.difference(y, z)   # => [4] (ONLY IN RUBY 2.6)
x - y                # => [4, 7]

INTERSECTION

x & y                # => [1, 2]

The W3C doc doesn't use concepts like wrong and sin, but it does use those like provide the means, may be appropriate and discouraged.

Actually, in the second paragraph of section 4, the 4.01 spec itemizes its words as follows

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. However, for readability, these words do not appear in all uppercase letters in this specification.

With that in mind, I believe the definitive statement is in 7.5.3 Block-level and inline elements, where it says

Generally, inline elements may contain only data and other inline elements.

The condition "generally" appears to introduce enough ambiguity to say that HTML 4.01 does allow inline elements to contain block elements.

Certainly, CSS2 has a display property value, inline-block, that appears to be suited to the purpose you describe. I'm not sure if it was ever widely supported, but it seems that someone anticipated the need for that kind of behavior.

The DTD appear to be less forgiving here, but the text of the DTD defers to the spec:

The HTML 4.01 specification includes additional syntactic constraints that cannot be expressed within the DTDs.

In another comment, you suggest that you want to make a block active by wrapping it in an anchor. I don't believe HTML prohibits that, and CSS clearly allows it. So to answer the title question about whether it is ever correct, I say yes. By the standards, it is sometimes correct.

I suggest following installation by no image show img.show() (from PIL import Image)

$ sudo apt-get install imagemagick

Well, if you have a number like 0.123456 that is the result of a division to give a percentage, multiply it by 100 and then either round it or use toFixed like in your example.

Math.round(0.123456 * 100) //12

Here is a jQuery plugin to do that:

jQuery.extend({
    percentage: function(a, b) {
        return Math.round((a / b) * 100);
    }
});

Usage:

alert($.percentage(6, 10));

CTRL+0 doesn't seem to work when connected to an Azure DB.

However, to create an empty string, you can always just hit 'anykey then delete' inside a cell.

You are comparing two objects for equality. The snippet:

if (obj == this) {     return true; } 

is a quick test that can be read

"If the object I'm comparing myself to is me, return true"

. You usually see this happen in equals methods so they can exit early and avoid other costly comparisons.

Rico Mariani, the .NET Performance guru, had an article on this very subject. It's not as simple as one might suspect. The basic advice is this:

If your pattern looks like:

x = f1(...) + f2(...) + f3(...) + f4(...)

that's one concat and it's zippy, StringBuilder probably won't help.

If your pattern looks like:

if (...) x += f1(...)
if (...) x += f2(...)
if (...) x += f3(...)
if (...) x += f4(...)

then you probably want StringBuilder.

Yet another article to support this claim comes from Eric Lippert where he describes the optimizations performed on one line + concatenations in a detailed manner.

Here's a variant of the solution from @JoshuaUlrich that uses the correct size instead of a hard-coded size:

fileName <- 'foo.txt'
readChar(fileName, file.info(fileName)$size)

Note that readChar allocates space for the number of bytes you specify, so readChar(fileName, .Machine$integer.max) does not work well...

I had the same problem. Most posted solutions would not work. I ran sfc /scannow and it reported that some errors could not be fixed. To address that problem I ran the command

Dism /Online /Cleanup-Image /RestoreHealth

Ironically, I later found the WAN errors had gone away, the 720 VPN error went away and my VPN worked.

Hard to believe that the WAN errors were corrected by this rather esoteric command, but it's worth a try.

TL;DR Use absolute paths to your assets (including your complete hostname) by setting your output.publicPath to e.g. "http://example.com/assets/".

The problem

The problem is the way that URLs are resolved by Chrome when they're parsed from a dynamically loaded CSS blob.

When you load the page, the browser loads your Webpack bundle entry JavaScript file, which (when you're using the style-loader) also contains a Base64 encoded copy of your CSS, which gets loaded into the page.

This is what it looks like in Chrome DevTools

That's fine for all the images or fonts which are encoded into the CSS as data URIs (i.e. the content of the file is embedded in the CSS), but for assets referenced by URL, the browser has to find and fetch the file.

Now by default the file-loader (which url-loader delegates to for large files) will use relative URLs to reference assets - and that's the problem!

These are the URLs generated by file-loader by default - relative URLs

When you use relative URLs, Chrome will resolve them relative to the containing CSS file. Ordinarily that's fine, but in this case the containing file is at blob://... and any relative URLs are referenced the same way. The end result is that Chrome attempts to load them from the parent HTML file, and ends up trying to parse the HTML file as the content of the font, which obviously won't work.

The Solution

Force the file-loader to use absolute paths including the protocol ("http" or "https").

Change your webpack config to include something equivalent to:

{
  output: {
    publicPath: "http://localhost:8080/", // Development Server
    // publicPath: "http://example.com/", // Production Server
  }
}

Now the URLs that it generates will look like this:

Absolute URLs!

These URLs will be correctly parsed by Chrome and every other browser.

Using extract-text-webpack-plugin

It's worth noting that if you're extracting your CSS to a separate file, you won't have this problem because your CSS will be in a proper file and URLs will be correctly resolved.

Update

All modern browsers now support the unprefixed event:

element.addEventListener('transitionend', callback, false);

https://caniuse.com/#feat=css-transitions

I was using the approach given by Pete, however I have now started using the following

$(".myClass").one('transitionend webkitTransitionEnd oTransitionEnd otransitionend MSTransitionEnd', 
function() {
 //do something
});

Alternatively if you use bootstrap then you can simply do

$(".myClass").one($.support.transition.end,
function() {
 //do something
});

This is becuase they include the following in bootstrap.js

+function ($) {
  'use strict';

  // CSS TRANSITION SUPPORT (Shoutout: http://www.modernizr.com/)
  // ============================================================

  function transitionEnd() {
    var el = document.createElement('bootstrap')

    var transEndEventNames = {
      'WebkitTransition' : 'webkitTransitionEnd',
      'MozTransition'    : 'transitionend',
      'OTransition'      : 'oTransitionEnd otransitionend',
      'transition'       : 'transitionend'
    }

    for (var name in transEndEventNames) {
      if (el.style[name] !== undefined) {
        return { end: transEndEventNames[name] }
      }
    }

    return false // explicit for ie8 (  ._.)
  }


  $(function () {
    $.support.transition = transitionEnd()
  })

}(jQuery);

Note they also include an emulateTransitionEnd function which may be needed to ensure a callback always occurs.

  // http://blog.alexmaccaw.com/css-transitions
  $.fn.emulateTransitionEnd = function (duration) {
    var called = false, $el = this
    $(this).one($.support.transition.end, function () { called = true })
    var callback = function () { if (!called) $($el).trigger($.support.transition.end) }
    setTimeout(callback, duration)
    return this
  }

Be aware that sometimes this event doesn’t fire, usually in the case when properties don’t change or a paint isn’t triggered. To ensure we always get a callback, let’s set a timeout that’ll trigger the event manually.

2021 Update...

Bootstrap 5 (beta)

For aligning within a flexbox div or row...

• ml-auto is now ms-auto
• mr-auto is now me-auto

Bootstrap 4+

• pull-right is now float-right
• text-right is the same as 3.x, and works for inline elements
• both float-* and text-* are responsive for different alignment at different widths (ie: float-sm-right)

The flexbox utils (eg:justify-content-between) can also be used for alignment:

<div class="d-flex justify-content-between">
      <div>
         left
      </div>
      <div>
         right
      </div>
 </div>

or, auto-margins (eg:ml-auto) in any flexbox container (row,navbar,card,d-flex,etc...)

<div class="d-flex">
      <div>
         left
      </div>
      <div class="ml-auto">
         right
      </div>
 </div>

Bootstrap 4 Align Demo
Bootstrap 4 Right Align Examples(float, flexbox, text-right, etc...)

Bootstrap 3

Use the pull-right class..

<div class="container">
  <div class="row">
    <div class="col-md-6">Total cost</div>
    <div class="col-md-6"><span class="pull-right">$42</span></div>
  </div>
</div>

Bootstrap 3 Demo

You can also use the text-right class like this:

  <div class="row">
    <div class="col-md-6">Total cost</div>
    <div class="col-md-6 text-right">$42</div>
  </div>

Bootstrap 3 Demo 2

I can suggest you a javascript oriented approach which makes it easy to work with javascript files in your project.

Create a javascript section in your jinja template file and place all variables you want to use in your javascript files in a window object:

Start.html

...
{% block scripts %}
<script type="text/javascript">
window.appConfig = {
    debug: {% if env == 'development' %}true{% else %}false{% endif %},
    facebook_app_id: {{ facebook_app_id }},
    accountkit_api_version: '{{ accountkit_api_version }}',
    csrf_token: '{{ csrf_token }}'
}
</script>
<script type="text/javascript" src="{{ url_for('static', filename='app.js') }}"></script>
{% endblock %}

Jinja will replace values and our appConfig object will be reachable from our other script files:

App.js

var AccountKit_OnInteractive = function(){
    AccountKit.init({
        appId: appConfig.facebook_app_id,
        debug: appConfig.debug,
        state: appConfig.csrf_token,
        version: appConfig.accountkit_api_version
    })
}

I have seperated javascript code from html documents with this way which is easier to manage and seo friendly.

The easiest way is using shift(). If you have an array, the shift function shifts everything to the left.

var arr = [1, 2, 3, 4]; 
var theRemovedElement = arr.shift(); // theRemovedElement == 1
console.log(arr); // [2, 3, 4]

Use a for loop to iterate through your array. For each string, create a new option element, assign the string as its innerHTML and value, and then append it to the select element.

var cuisines = ["Chinese","Indian"];     
var sel = document.getElementById('CuisineList');
for(var i = 0; i < cuisines.length; i++) {
    var opt = document.createElement('option');
    opt.innerHTML = cuisines[i];
    opt.value = cuisines[i];
    sel.appendChild(opt);
}

DEMO

UPDATE: Using createDocumentFragment and forEach

If you have a very large list of elements that you want to append to a document, it can be non-performant to append each new element individually. The DocumentFragment acts as a light weight document object that can be used to collect elements. Once all your elements are ready, you can execute a single appendChild operation so that the DOM only updates once, instead of n times.

var cuisines = ["Chinese","Indian"];     

var sel = document.getElementById('CuisineList');
var fragment = document.createDocumentFragment();

cuisines.forEach(function(cuisine, index) {
    var opt = document.createElement('option');
    opt.innerHTML = cuisine;
    opt.value = cuisine;
    fragment.appendChild(opt);
});

sel.appendChild(fragment);

To define "soft real-time," it is easiest to compare it with "hard real-time." Below we will see that the term "firm real-time" constitutes a misunderstanding about "soft real-time."

Speaking casually, most people implicitly have an informal mental model that considers information or an event as being "real-time"

• if, or to the extent that, it is manifest to them with a delay (latency) that can be related to its perceived currency

• i.e., in a time frame that the information or event has acceptably satisfactory value to them.

There are numerous different ad hoc definitions of "hard real-time," but in that mental model, hard real-time is represented by the "if" term. Specifically, assuming that real-time actions (such as tasks) have completion deadlines, acceptably satisfactory value of the event that all tasks complete is limited to the special case that all tasks meet their deadlines.

Hard real-time systems make the very strong assumptions that everything about the application and system and environment is static and known a' priori—e.g., which tasks, that they are periodic, their arrival times, their periods, their deadlines, that they won’t have resource conflicts, and overall the time evolution of the system. In an aircraft flight control system or automotive braking system and many other cases those assumptions can usually be satisfied so that all the deadlines will be met.

This mental model is deliberately and very usefully general enough to encompass both hard and soft real-time--soft is accommodated by the "to the extent that" phrase. For example, suppose that the task completions event has suboptimal but acceptable value if

• no more than 10% of the tasks miss their deadlines
• or no task is more than 20% tardy
• or the average tardiness of all tasks is no more than 15%
• or the maximum tardiness among all tasks is less than 10%

These are all common examples of soft real-time cases in a great many applications.

Consider the single-task application of picking your child up after school. That probably does not have an actual deadline, instead there is some value to you and your child based on when that event takes place. Too early wastes resources (such as your time) and too late has some negative value because your child might be left alone and potentially in harm's way (or at least inconvenienced).

Unlike the static hard real-time special case, soft real-time makes only the minimum necessary application-specific assumptions about the tasks and system, and uncertainties are expected. To pick up your child, you have to drive to the school, and the time to do that is dynamic depending on weather, traffic conditions, etc. You might be tempted to over-provision your system (i.e., allow what you hope is the worst case driving time) but again this is wasting resources (your time, and occupying the family vehicle, possibly denying use by other family members).

That example may not seem to be costly in terms of wasted resources, but consider other examples. All military combat systems are soft real-time. For example, consider performing an aircraft attack on a hostile ground vehicle using a missile guided with updates to it as the target maneuvers. The maximum satisfaction for completing the course update tasks is achieved by a direct destructive strike on the target. But an attempt to over-provision resources to make certain of this outcome is usually far too expensive and may even be impossible. In this case, you may be less but sufficiently satisfied if the missile strikes close enough to the target to disable it.

Obviously combat scenarios have a great many possible dynamic uncertainties that must be accommodated by the resource management. Soft real-time systems are also very common in many civilian systems, such as industrial automation, although obviously military ones are the most dangerous and urgent ones to achieve acceptably satisfactory value in.

The keystone of real-time systems is "predictability." The hard real-time case is interested in only one special case of predictability--i.e., that the tasks will all meet their deadlines and the maximum possible value will be achieved by that event. That special case is named "deterministic."

There is a spectrum of predictability. Deterministic (determinism) is one end-point (maximum predictability) on the predictability spectrum; the other end-point is minimum predictability (maximum non-determinism). The spectrum's metric and end-points have to be interpreted in terms of a chosen predictability model; everything between those two end-points is degrees of unpredictability (= degrees of non-determinism).

Most real-time systems (namely, soft ones) have non-deterministic predictability, for example, of the tasks' completions times and hence the values gained from those events.

In general (in theory), predictability, and hence acceptably satisfactory value, can be made as close to the deterministic end-point as necessary--but at a price which may be physically impossible or excessively expensive (as in combat or perhaps even in picking up your child from school).

Soft real-time requires an application-specific choice of a probability model (not the common frequentist model) and hence predictability model for reasoning about event latencies and resulting values.

Referring back to the above list of events that provide acceptable value, now we can add non-deterministic cases, such as

• the probability that no task will miss its deadline by more than 5% is greater than 0.87. (Note the number of scheduling criteria expressed in there.)

In a missile defense application, given the fact that in combat the offense always has the advantage over the defense, which of these two real-time computing scenarios would you prefer:

• because the perfect destruction of all the hostile missiles is very unlikely or impossible, assign your defensive resources to maximize the probability that as many of the most threatening (e.g., based on their targets) hostile missiles will be successfully intercepted (close interception counts because it can move the hostile missile off-course);

• complain that this is not a real-time computing problem because it is dynamic instead of static, and traditional real-time concepts and techniques do not apply, and it sounds more difficult than static hard real-time, so you are not interested in it.

Despite the various misunderstandings about soft real-time in the real-time computing community, soft real-time is very general and powerful, albeit potentially complex compared with hard real-time. Soft real-time systems as summarized here have a lengthy successful history of use outside the real-time computing community.

To directly answer the OP question:

A hard real-time system can provide deterministic guarantees—most commonly that all tasks will meet their deadlines, interrupt or system call response time will always be less than x, etc.—IF AND ONLY IF very strong assumptions are made and are correct that everything that matters is static and known a' priori (in general, such guarantees for hard real-time systems are an open research problem except for rather simple cases)

A soft real-time system does not make deterministic guarantees, it is intended to provide the best possible analytically specified and accomplished probabilistic timeliness and predictability of timeliness that are feasible under the current dynamic circumstances, according to application-specific criteria.

Obviously hard real-time is a simple special case of soft real-time. Obviously soft real-time's analytical non-deterministic assurances can be very complex to provide, but are mandatory in the most common real-time cases (including the most dangerous safety-critical ones such as combat) since most real-time cases are dynamic not static.

"Firm real-time" is an ill-defined special case of "soft real-time." There is no need for this term if the term "soft real-time" is understood and used properly.

I have a more detailed much more precise discussion of real-time, hard real-time, soft real-time, predictability, determinism, and related topics on my web site real-time.org.

To convert a field of string type to date field, you would need to iterate the cursor returned by the find() method using the forEach() method, within the loop convert the field to a Date object and then update the field using the $set operator.

Take advantage of using the Bulk API for bulk updates which offer better performance as you will be sending the operations to the server in batches of say 1000 which gives you a better performance as you are not sending every request to the server, just once in every 1000 requests.

The following demonstrates this approach, the first example uses the Bulk API available in MongoDB versions >= 2.6 and < 3.2. It updates all the documents in the collection by changing all the created_at fields to date fields:

var bulk = db.collection.initializeUnorderedBulkOp(),
    counter = 0;

db.collection.find({"created_at": {"$exists": true, "$type": 2 }}).forEach(function (doc) {
    var newDate = new Date(doc.created_at);
    bulk.find({ "_id": doc._id }).updateOne({ 
        "$set": { "created_at": newDate}
    });

    counter++;
    if (counter % 1000 == 0) {
        bulk.execute(); // Execute per 1000 operations and re-initialize every 1000 update statements
        bulk = db.collection.initializeUnorderedBulkOp();
    }
})
// Clean up remaining operations in queue
if (counter % 1000 != 0) { bulk.execute(); }

The next example applies to the new MongoDB version 3.2 which has since deprecated the Bulk API and provided a newer set of apis using bulkWrite():

var bulkOps = [];

db.collection.find({"created_at": {"$exists": true, "$type": 2 }}).forEach(function (doc) { 
    var newDate = new Date(doc.created_at);
    bulkOps.push(         
        { 
            "updateOne": { 
                "filter": { "_id": doc._id } ,              
                "update": { "$set": { "created_at": newDate } } 
            }         
        }           
    );     
})

db.collection.bulkWrite(bulkOps, { "ordered": true });

Try this

System.Net.WebUtility.HtmlDecode(string);
System.Net.WebUtility.HtmlEncode(string);

columnDefinition will override the sql DDL generated by hibernate for this particular column, it is non portable and depends on what database you are using. You can use it to specify nullable, length, precision, scale... ect.

Sorry, I read jsp not javascript. You need to do something like (note that this is a relative url and may be different depending on the url of the document this javascript is in):

document.location = 'path/to/servlet';

Where your servlet-mapping in web.xml looks something like this:

<servlet-mapping>
    <servlet-name>someServlet</servlet-name>
    <url-pattern>/path/to/servlet*</url-pattern>
</servlet-mapping>

1. Find file:

   [XAMPP Installation Directory]\php\php.ini
   

2. open php.ini.
3. Find max_execution_time and increase the value of it as you required
4. Restart XAMPP control panel

I had the same issue when I changed the home directory of one use. In my case it was because of selinux. I used the below to fix the issue:

selinuxenabled 0
setenforce 0

The --force option will reinstall already installed packages or overwrite already installed files from other packages. You don't want this normally.

If you tell rpm to install all RPMs from some directory, then it does exactly this. rpm will not ignore RPMs listed for installation. You must manually remove the unneeded RPMs from the list (or directory). It will always overwrite the files with the "latest RPM installed" whichever order you do it in.

You can remove the old RPM and rpm will resolve the dependency with the newer version of the installed RPM. But this will only work, if none of the to be installed RPMs depends exactly on the old version.

If you really need different versions of the same RPM, then the RPM must be relocatable. You can then tell rpm to install the specific RPM to a different directory. If the files are not conflicting, then you can just install different versions with rpm -i (zypper in can not install different versions of the same RPM). I am packaging for example ruby gems as relocatable RPMs at work. So I can have different versions of the same gem installed.

I don't know on which files your RPMs are conflicting, but if all of them are "just" man pages, then you probably can simply overwrite the new ones with the old ones with rpm -i --replacefiles. The only problem with this would be, that it could confuse somebody who is reading the old man page and thinks it is for the actual version. Another problem would be the rpm --verify command. It will complain for the new package if the old one has overwritten some files.

Is this possibly a duplicate of https://serverfault.com/questions/522525/rpm-ignore-conflicts?

I couldn't get the form suggested by @thoredge to work in Gradle 1.11, but this works for me:

home = System.getenv('HOME')

It helps to keep in mind that anything that works in pure Java will work in Gradle too.

Vinay is correct. In answer to your comment in his answer, one way you can do it is as follows:

<root>
    <level value="ALL" />
    <appender-ref ref="File1Appender" />
</root>
<logger name="SomeName">
    <level value="ALL" />
    <appender-ref ref="File1Appender2" />
</logger>

This is how I have done it in the past. Then something like this for the other log:

private static readonly ILog otherLog = LogManager.GetLogger("SomeName");

And you can get your normal logger as follows:

private static readonly ILog log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);

Read the loggers and appenders section of the documentation to understand how this works.

I used the CREATE TABLE AS syntax to merge several columns and encountered the same problem. Here is an AppleScript I wrote to speed the process up.

set databasePath to "~/Documents/Databases/example.db"
set tableOne to "separate" -- Table from which you are pulling data
set tableTwo to "merged" -- Table you are creating
set {tempCol, tempColEntry, permColEntry} to {{}, {}, {}}
set permCol to {"id integer primary key"}

-- Columns are created from single items  AND from the last item of a list
-- {{"a", "b", "c"}, "d", "e"} Columns "a" and "b" will be merged into a new column "c".  tableTwo will have columns "c", "d", "e"

set nonCoal to {"City", "Contact", "Names", {"Address 1", "Address", "address one", "Address1", "Text4", "Address 1"}, {"E-Mail", "E-Mail Address", "Email", "Email Address", "EmailAddress", "Email"}, {"Zip", "Zip Code", "ZipCode", "Zip"}, {"Telephone", "BusinessPhone", "Phone", "Work Phone", "Telephone"}, {"St", "State", "State"}, {"Salutation", "Mr/Ms", "Mr/s", "Salutations", "Sautation", "Salutation"}}

-- Build the COALESCE statements
repeat with h from 1 to count of nonCoal
set aColumn to item h of nonCoal
if class of aColumn is not list then
    if (count of words of aColumn) > 1 then set aColumn to quote & aColumn & quote
    set end of tempCol to aColumn
    set end of permCol to aColumn
else
    set coalEntry to {}
    repeat with i from 1 to count of aColumn
        set coalCol to item i of aColumn as string
        if (count of words of coalCol) > 1 then set coalCol to quote & coalCol & quote
        if i = 1 then
            set end of coalEntry to "TRIM(COALESCE(" & coalCol & ", '') || \" \" || "
        else if i < ((count of aColumn) - 1) then
            set end of coalEntry to "COALESCE(" & coalCol & ", '') || \" \" || "
        else if i = ((count of aColumn) - 1) then
            set as_Col to item (i + 1) of aColumn as string
            if (count of words of as_Col) > 1 then set as_Col to quote & as_Col & quote
            set end of coalEntry to ("COALESCE(" & coalCol & ", '')) AS " & as_Col) & ""
            set end of permCol to as_Col
        end if
    end repeat
    set end of tempCol to (coalEntry as string)
end if
end repeat

-- Since there are ", '' within the COALESCE statement, you can't use "TID" and "as string" to convert tempCol and permCol for entry into sqlite3. I rebuild the lists in the next block.
repeat with j from 1 to count of tempCol
if j < (count of tempCol) then
    set end of tempColEntry to item j of tempCol & ", "
    set end of permColEntry to item j of permCol & ", "
else
    set end of tempColEntry to item j of tempCol
    set end of permColEntry to item j of permCol
end if
end repeat
set end of permColEntry to ", " & item (j + 1) of permCol
set permColEntry to (permColEntry as string)
set tempColEntry to (tempColEntry as string)

-- Create the new table with an "id integer primary key" column
set createTable to "create table " & tableTwo & " (" & permColEntry & "); "
do shell script "sqlite3 " & databasePath & space & quoted form of createTable

-- Create a temporary table and then populate the permanent table
set createTemp to "create temp table placeholder as select " & tempColEntry & " from " & tableOne & ";  " & "insert into " & tableTwo & " select Null, * from placeholder;"
do shell script "sqlite3 " & databasePath & space & quoted form of createTemp

--export the new table as a .csv file
do shell script "sqlite3 -header -column -csv " & databasePath & " \"select * from " & tableTwo & " ; \"> ~/" & tableTwo & ".csv"

Have a look at the following

@using (Html.BeginForm("FileUpload", "Home", FormMethod.Post, 
                            new { enctype = "multipart/form-data" }))
{  
    <label for="file">Upload Image:</label> 
    <input type="file" name="file" id="file" style="width: 100%;" /> 
    <input type="submit" value="Upload" class="submit" /> 
}

your controller should have action method which would accept HttpPostedFileBase;

 public ActionResult FileUpload(HttpPostedFileBase file)
    {
        if (file != null)
        {
            string pic = System.IO.Path.GetFileName(file.FileName);
            string path = System.IO.Path.Combine(
                                   Server.MapPath("~/images/profile"), pic); 
            // file is uploaded
            file.SaveAs(path);

            // save the image path path to the database or you can send image 
            // directly to database
            // in-case if you want to store byte[] ie. for DB
            using (MemoryStream ms = new MemoryStream()) 
            {
                 file.InputStream.CopyTo(ms);
                 byte[] array = ms.GetBuffer();
            }

        }
        // after successfully uploading redirect the user
        return RedirectToAction("actionname", "controller name");
    }

Update 1

In case you want to upload files using jQuery with asynchornously, then try this article.

the code to handle the server side (for multiple upload) is;

 try
    {
        HttpFileCollection hfc = HttpContext.Current.Request.Files;
        string path = "/content/files/contact/";

        for (int i = 0; i < hfc.Count; i++)
        {
            HttpPostedFile hpf = hfc[i];
            if (hpf.ContentLength > 0)
            {
                string fileName = "";
                if (Request.Browser.Browser == "IE")
                {
                    fileName = Path.GetFileName(hpf.FileName);
                }
                else
                {
                    fileName = hpf.FileName;
                }
                string fullPathWithFileName = path + fileName;
                hpf.SaveAs(Server.MapPath(fullPathWithFileName));
            }
        }

    }
    catch (Exception ex)
    {
        throw ex;
    }

this control also return image name (in a javascript call back) which then you can use it to display image in the DOM.

UPDATE 2

Alternatively, you can try Async File Uploads in MVC 4.

There is a better way to do this:

If the array $arr_options contains the existing array.

$arr_new_input['name'] = [
    'type' => 'text', 
    'label' => 'First name', 
    'show' => true, 
    'required' => true
];

$arr_options += $arr_new_input;

Warning: $arr_options must exist. if $arr_options already has a ['name'] it wil be overwritten.

Hope this helps.

Use this SQL command to drop a unique constraint:

ALTER TABLE tbl_name
DROP INDEX column_name

I wanted a more exact and useful answer to this question. Here's the real answer (adjust accordingly if you want a byte array specifically; obviously the math will be off by a factor of 8 bits : 1 byte):

class BitArray {
  constructor(bits = 0) {
    this.uints = new Uint32Array(~~(bits / 32));
  }

  getBit(bit) {
    return (this.uints[~~(bit / 32)] & (1 << (bit % 32))) != 0 ? 1 : 0;
  }

  assignBit(bit, value) {
    if (value) {
      this.uints[~~(bit / 32)] |= (1 << (bit % 32));
    } else {
      this.uints[~~(bit / 32)] &= ~(1 << (bit % 32));
    }
  }

  get size() {
    return this.uints.length * 32;
  }

  static bitsToUints(bits) {
    return ~~(bits / 32);
  }
}

Usage:

let bits = new BitArray(500);
for (let uint = 0; uint < bits.uints.length; ++uint) {
  bits.uints[uint] = 457345834;
}
for (let bit = 0; bit < 50; ++bit) {
  bits.assignBit(bit, 1);
}
str = '';
for (let bit = bits.size - 1; bit >= 0; --bit) {
  str += bits.getBit(bit);
}
str;

Output:

"00011011010000101000101100101010
 00011011010000101000101100101010

 11111111111111111111111111111111"

Note: This class is really slow to e.g. assign bits (i.e. ~2s per 10 million assignments) if it's created as a global variable, at least in the Firefox 76.0 Console on Linux... If, on the other hand, it's created as a variable (i.e. let bits = new BitArray(1e7);), then it's blazingly fast (i.e. ~300ms per 10 million assignments)!

For more info, see here:

• "How do you set, clear and toggle a single bit in JavaScript?": https://stackoverflow.com/a/1436448/1599699

• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Typed_arrays
• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint32Array

Note that I used Uint32Array because there's no way to directly have a bit/byte array (that you can interact with directly) and because even though there's a BigUint64Array, JS only supports 32 bits:

Bitwise operators treat their operands as a sequence of 32 bits

...

The operands of all bitwise operators are converted to...32-bit integers

The problem is that if you include fun.cpp in two places in your program, you will end up defining it twice, which isn't valid.

You don't want to include cpp files. You want to include header files.

The header file should just have the class definition. The corresponding cpp file, which you will compile separately, will have the function definition.

fun.hpp:

#include <iostream>

class classA {
    friend void funct();
public:
    classA(int a=1,int b=2):propa(a),propb(b){std::cout<<"constructor\n";}
private:
    int propa;
    int propb;
    void outfun(){
        std::cout<<"propa="<<propa<<endl<<"propb="<<propb<< std::endl;
    }
};

fun.cpp:

#include "fun.hpp"

using namespace std;

void funct(){
    cout<<"enter funct"<<endl;
    classA tmp(1,2);
    tmp.outfun();
    cout<<"exit funct"<<endl;
}

mainfile.cpp:

#include <iostream>
#include "fun.hpp"
using namespace std;

int main(int nargin,char* varargin[]) {
    cout<<"call funct"<<endl;
    funct();
    cout<<"exit main"<<endl;
    return 0;
}

Note that it is generally recommended to avoid using namespace std in header files.

1. df.iloc[0].head(1) - First data set only from entire first row.
2. df.iloc[0] - Entire First row in column.

msiexec.exe /x "{588A9A11-1E20-4B91-8817-2D36ACBBBF9F}" /q 

Your XML is not entirely clear, but arrays XML can cause force closes if you make them numbers, and/or put white space in their definition.

Make sure they are defined like No Leading or Trailing Whitespace

For appium 1.6.0 and above

    WebElement button = (new WebDriverWait(driver, 10).until(ExpectedConditions.presenceOfElementLocated(By.xpath("//XCUIElementTypeButton[@name='your button']"))));
    button.click();

    Assert.assertTrue(!button.isDisplayed());

This suffices and stores the first line of filename in the variable $line:

read -r line < filename

I also like awk for this:

awk 'NR==1 {print; exit}' file

To store the line itself, use the var=$(command) syntax. In this case, line=$(awk 'NR==1 {print; exit}' file).

Or even sed:

sed -n '1p' file

With the equivalent line=$(sed -n '1p' file).

See a sample when we feed the read with seq 10, that is, a sequence of numbers from 1 to 10:

$ read -r line < <(seq 10) 
$ echo "$line"
1

$ line=$(awk 'NR==1 {print; exit}' <(seq 10))
$ echo "$line"
1

You could do this, it doesn't require LINQ, but it's not the best way to do it(since you make split the whole string and put it in an array and just pick the length of it, you could better just do a while loop and check every character), but it works.

int count = test.Split('$').Length - 1;
