For myself this happened in SourceTree when I tried to commit a merge before resolving all of the files. I then marked the last file resolved and yet it still gave me this error when trying to commit. I closed SourceTree and reopened it, and then it committed fine.

Further to pensz answer you can get more info using:

DESCRIBE EXTENDED my_table;

or

DESCRIBE EXTENDED my_table PARTITION (my_column='my_value');

Be sure there is nothing on your button (such a div or a trasparent img) that keeps from clicking the button. It sounds stupid, but sometimes we think that jQuery is not working and all that stuffs and the problem is on the positioning of DOM elements.

The solutions above are great for interactive use, where you can eyeball the result and weed out false positives that way.

False positives can occur if the executable itself happens to match, or any arguments that are not script names match - the likelihood is greater with scripts that have no filename extensions.

Here's a more robust solution for scripting, using a shell function:

getscript() {
  pgrep -lf ".[ /]$1( |\$)"
}

Example use:

# List instance(s) of script "aa.sh" that are running.
getscript "aa.sh"  # -> (e.g.): 96112 bash /Users/jdoe/aa.sh

# Use in a test:
if getscript "aa.sh" >/dev/null; then
  echo RUNNING
fi

• Matching is case-sensitive (on macOS, you could add -i to the pgrep call to make it case-insensitive; on Linux, that is not an option.)
• The getscript function also works with full or partial paths that include the filename component; partial paths must not start with / and each component specified must be complete. The "fuller" the path specified, the lower the risk of false positives. Caveat: path matching will only work if the script was invoked with a path - this is generally true for scripts in the $PATH that are invoked directly.
• Even this function cannot rule out all false positives, as paths can have embedded spaces, yet neither ps nor pgrep reflect the original quoting applied to the command line. All the function guarantees is that any match is not the first token (which is the interpreter), and that it occurs as a separate word, optionally preceded by a path.
• Another approach to minimizing the risk of false positives could be to match the executable name (i.e., interpreter, such as bash) as well - assuming it is known; e.g.

# List instance(s) of a running *bash* script.
getbashscript() {
  pgrep -lf "(^|/)bash( | .*/)$1( |\$)"
}

If you're willing to make further assumptions - such as script-interpreter paths never containing embedded spaces - the regexes could be made more restrictive and thus further reduce the risk of false positives.

VB.net, Desktop application. If you need lapsed time in milliseconds:

Dim starts As Integer = My.Computer.Clock.TickCount
Dim ends As Integer = My.Computer.Clock.TickCount
Dim lapsed As Integer = ends - starts

Split string in JavaScript

var array = str.match(/[^\r\n]+/g);

OR

var array = str.split(/\r?\n/);

new JwtSecurityTokenHandler().ReadToken("") will return a SecurityToken

new JwtSecurityTokenHandler().ReadJwtToken("") will return a JwtSecurityToken

If you just change the method you are using you can avoid the cast in the above answer

You could also do this:

#!/usr/bin/perl

use strict;
use warnings;

$^I = '.bak'; # create a backup copy 

while (<>) {
   s/<PREF>/ABCD/g; # do the replacement
   print; # print to the modified file
}

Invoke the script with by

./script.pl input_file

You will get a file named input_file, containing your changes, and a file named input_file.bak, which is simply a copy of the original file.

My site configuration file is example.conf in sites-available folder So you can create a symbolic link as

ln -s /etc/nginx/sites-available/example.conf /etc/nginx/sites-enabled/

Works for me

UIView *customColorView = [[UIView alloc] init];
    customColorView.backgroundColor = [UIColor colorWithRed:180/255.0 
                                                      green:138/255.0 
                                                       blue:171/255.0 
                                                      alpha:0.5];
    cell.selectedBackgroundView =  customColorView;

In some cases, nvl(sum(column_name),0) is also required. You may want to consider your scenarios.

For example, I am trying to fetch the sum of a particular column, from a particular table based on certain conditions. Based on the conditions,

1. one or more rows exist in the table. In this case I want the sum.
2. rows do not exist. In this case I want 0.

If you use sum(nvl(column_name,0)) here, it would give you null. What you might want is nvl(sum(column_name),0).

This may be required especially when you are passing this result to, say, java, have the datatype as number there because then this will not require special null handling.

You need to use Arrow function ()=> ES6 feature to preserve this context within setTimeout.

// var that = this;                             // no need of this line
this.messageSuccess = true;

setTimeout(()=>{                           //<<<---using ()=> syntax
      this.messageSuccess = false;
 }, 3000);

You can use LENGTH() for CHAR / VARCHAR2 and DBMS_LOB.GETLENGTH() for CLOB. Both functions will count actual characters (not bytes).

See the linked documentation if you do need bytes.

Best way is to Use a Python Web Frame Work you can choose Django/Flask. I will suggest you to Use Django because it's more powerful. Here is Step by guide to get complete your task :

pip install django
django-admin createproject buttonpython

then you have to create a file name views.py in buttonpython directory.

write below code in views.py:

from django.http import HttpResponse

def sample(request):
    #your python script code
    output=code output
    return HttpResponse(output)

Once done navigate to urls.py and add this stanza

from . import views

path('', include('blog.urls')),

Now go to parent directory and execute manage.py

python manage.py runserver 127.0.0.1:8001

Step by Step Guide in Detail: Run Python script on clicking HTML button

$ join -v 1 -t '' file1 file2
line2
line3

The -t makes sure that it compares the whole line, if you had a space in some of the lines.

In React, the component will re-render (or update) only if the state or the prop changes.

In your case you have to update the state immediately after the change so that the component will re-render with the updates state value.

onTodoChange(event) {
        // update the state
    this.setState({name: event.target.value});
}

int i = 25;
NSString *myString = [NSString stringWithFormat:@"%d",i];

This is one of many ways.

The Communicating with Other Fragments guide says the Fragments should communicate through the associated Activity.

Often you will want one Fragment to communicate with another, for example to change the content based on a user event. All Fragment-to-Fragment communication is done through the associated Activity. Two Fragments should never communicate directly.

From Oracle docs, Date.toString() method convert Date object to a String of the specific form - do not use toString method on Date object. Try to use:

String stringDate = new SimpleDateFormat(YOUR_STRING_PATTERN).format(yourDateObject);

Next step is parse stringDate to Date:

Date date = new SimpleDateFormat(OUTPUT_PATTERN).parse(stringDate);

Note that, parse method throws ParseException

This will list Everything (including sub directories) from the directory you specify, in order, and with the attributes. I have spent days looking for something to do this, and I took parts from this entire discussion, and a little of my own, and put it together. ENJOY!!

#!/usr/bin/perl --
print qq~Content-type: text/html\n\n~;
print qq~<font face="arial" size="2">~;

use File::Find;

# find( \&wanted_tom, '/home/thomas/public_html'); # if you want just one website, uncomment this, and comment out the next line
find( \&wanted_tom, '/home');
exit;

sub wanted_tom {
($dev,$ino,$mode,$nlink,$uid,$gid,$rdev,$size,$atime,$mtime,$ctime,$blksize,$blocks) = stat ($_);
$mode = (stat($_))[2];
$mode = substr(sprintf("%03lo", $mode), -3);

if (-d $File::Find::name) {
print "<br><b>--DIR $File::Find::name --ATTR:$mode</b><br>";
 } else {
print "$File::Find::name --ATTR:$mode<br>";
 }
  return;
}

Use a subquery:

SELECT * FROM 
(
    SELECT * FROM users ORDER BY rand() LIMIT 20
) T1
ORDER BY name 

The inner query selects 20 users at random and the outer query orders the selected users by name.

For synchronous renaming use fs.renameSync

fs.renameSync('/path/to/Afghanistan.png', '/path/to/AF.png');

You don't need a regex for this. Use tr:

"some text\nandsomemore".tr("\n","")

I managed to render the following SELECT with SQLAlchemy on both layers.

SELECT count(*) AS count_1
FROM "table"

Usage from the SQL Expression layer

from sqlalchemy import select, func, Integer, Table, Column, MetaData

metadata = MetaData()

table = Table("table", metadata,
              Column('primary_key', Integer),
              Column('other_column', Integer)  # just to illustrate
             )   

print select([func.count()]).select_from(table)

Usage from the ORM layer

You just subclass Query (you have probably anyway) and provide a specialized count() method, like this one.

from sqlalchemy.sql.expression import func

class BaseQuery(Query):
    def count_star(self):
        count_query = (self.statement.with_only_columns([func.count()])
                       .order_by(None))
        return self.session.execute(count_query).scalar()

Please note that order_by(None) resets the ordering of the query, which is irrelevant to the counting.

Using this method you can have a count(*) on any ORM Query, that will honor all the filter andjoin conditions already specified.

Add property of show header in gridview

 <asp:GridView ID="dgvUsers" runat="server" **showHeader="True"** CssClass="table table-hover table-striped" GridLines="None" 
AutoGenerateColumns="False">

and in columns add header template

<HeaderTemplate>
                   //header column names
</HeaderTemplate>

Translating language codes such as en_US into English (United States) is a built in feature of NSLocale and NSLocale does not care where you get the language codes from. So there really is no reason to implement your own translation as the accepted answer suggests.

// Example code - try changing the language codes and see what happens
NSLocale *locale = [[NSLocale alloc] initWithLocaleIdentifier:@"en"];
NSString *l1 = [locale displayNameForKey:NSLocaleIdentifier value:@"en"];
NSString *l2 = [locale displayNameForKey:NSLocaleIdentifier value:@"de"];
NSString *l3 = [locale displayNameForKey:NSLocaleIdentifier value:@"sv"];
NSLog(@"%@, %@, %@", l1, l2, l3);

Prints: English, German, Swedish

For future Googlers i've a different approach to check if it's last element. It's similar to last lines in OP question.

This directly compares elements rather than just checking index numbers.

$yourset.each(function() {
    var $this = $(this);
    if($this[0] === $yourset.last()[0]) {
        //$this is the last one
    }
});

The interpretation of the backspace and carriage return characters is left to the software you use for display. A terminal emulator, when displaying \b would move the cursor one step back, and when displaying \r to the beginning of the line. If you print these characters somewhere else, like a text file, the software may choose. to do something else.

Yes, #id selectors combined with a multiple selector (comma) is perfectly valid in both jQuery and CSS.

However, for your example, since <script> comes before the elements, you need a document.ready handler, so it waits until the elements are in the DOM to go looking for them, like this:

<script>
  $(function() {
    $("#segement1,#segement2,#segement3").hide()
  });
</script>

<div id="segement1"></div>
<div id="segement2"></div>
<div id="segement3"></div>

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

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

__del__ is a finalizer. It is called when an object is garbage collected which happens at some point after all references to the object have been deleted.

In a simple case this could be right after you say del x or, if x is a local variable, after the function ends. In particular, unless there are circular references, CPython (the standard Python implementation) will garbage collect immediately.

However, this is an implementation detail of CPython. The only required property of Python garbage collection is that it happens after all references have been deleted, so this might not necessary happen right after and might not happen at all.

Even more, variables can live for a long time for many reasons, e.g. a propagating exception or module introspection can keep variable reference count greater than 0. Also, variable can be a part of cycle of references — CPython with garbage collection turned on breaks most, but not all, such cycles, and even then only periodically.

Since you have no guarantee it's executed, one should never put the code that you need to be run into __del__() — instead, this code belongs to finally clause of the try block or to a context manager in a with statement. However, there are valid use cases for __del__: e.g. if an object X references Y and also keeps a copy of Y reference in a global cache (cache['X -> Y'] = Y) then it would be polite for X.__del__ to also delete the cache entry.

If you know that the destructor provides (in violation of the above guideline) a required cleanup, you might want to call it directly, since there is nothing special about it as a method: x.__del__(). Obviously, you should you do so only if you know that it doesn't mind to be called twice. Or, as a last resort, you can redefine this method using

type(x).__del__ = my_safe_cleanup_method  

I have a jQuery plugin on GitHub: https://github.com/MartinF/jQuery.Autosize.Input

It mirrors the value of the input, calculates the width and uses it for setting the width of the input.

You can see an live example here: http://jsfiddle.net/mJMpw/2175/

Example of how to use it (because some code is needed when posting a jsfiddle link):

<input type="text" value="" placeholder="Autosize" data-autosize-input='{ "space": 40 }' />

input[type="data-autosize-input"] {
  width: 90px;
  min-width: 90px;
  max-width: 300px;
  transition: width 0.25s;    
}

You just use css to set min/max-width and use a transition on the width if you want a nice effect.

You can specify the space / distance to the end as the value in json notation for the data-autosize-input attribute on the input element.

Of course you can also just initialize it using jQuery

$("selector").autosizeInput();

Extend LinearLayout/RelativeLayout and use it straight on the XML

package com.pkg_name ;
...imports...
public class LinearLayoutOutlined extends LinearLayout {
    Paint paint;    

    public LinearLayoutOutlined(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
        setWillNotDraw(false) ;
        paint = new Paint();
    }
    public LinearLayoutOutlined(Context context, AttributeSet attrs) {
        super(context, attrs);
        // TODO Auto-generated constructor stub
        setWillNotDraw(false) ;
        paint = new Paint();
    }
    @Override
    protected void onDraw(Canvas canvas) {
        /*
        Paint fillPaint = paint;
        fillPaint.setARGB(255, 0, 255, 0);
        fillPaint.setStyle(Paint.Style.FILL);
        canvas.drawPaint(fillPaint) ;
        */

        Paint strokePaint = paint;
        strokePaint.setARGB(255, 255, 0, 0);
        strokePaint.setStyle(Paint.Style.STROKE);
        strokePaint.setStrokeWidth(2);  
        Rect r = canvas.getClipBounds() ;
        Rect outline = new Rect( 1,1,r.right-1, r.bottom-1) ;
        canvas.drawRect(outline, strokePaint) ;
    }

}

<?xml version="1.0" encoding="utf-8"?>

<com.pkg_name.LinearLayoutOutlined
   xmlns:android="http://schemas.android.com/apk/res/android"
   android:orientation="vertical"
    android:layout_width=...
    android:layout_height=...
   >
   ... your widgets here ...

</com.pkg_name.LinearLayoutOutlined>

This one really works. Also has the benefit that you can use media queries to easily turn off the horizontal style — for instance if you want to stack them vertically when on mobile phone.

if your value is a pure text (like 'test') you could use the text() method as well. like this:

$('div.total-title').text('test');

anyway, about the problem you are sharing, I think you might be calling the JavaScript code before the HTML code for the DIV is being sent to the browser. make sure you are calling the jQuery line in a <script> tag after the <div>, or in a statement like this:

$(document).ready(
    function() {
        $('div.total-title').text('test');
    }
);

this way the script executes after the HTML of the div is parsed by the browser.

I managed to stop by adding those 2 lines

TheNewIdiot's answer successfully explains the problem and the reason why you can't send attributes in request through a redirect. Possible solutions:

1. Using forwarding. This will enable that request attributes could be passed to the view and you can use them in form of ServletRequest#getAttribute or by using Expression Language and JSTL. Short example (reusing TheNewIdiot's answer] code).

   Controller (your servlet)

   request.setAttribute("message", "Hello world");
   RequestDispatcher dispatcher = servletContext().getRequestDispatcher(url);
   dispatcher.forward(request, response);
   

   View (your JSP)

   Using scriptlets:

   <%
       out.println(request.getAttribute("message"));
   %>
   

   This is just for information purposes. Scriptlets usage must be avoided: How to avoid Java code in JSP files?. Below there is the example using EL and JSTL.

   <c:out value="${message}" />
   

2. If you can't use forwarding (because you don't like it or you don't feel it that way or because you must use a redirect) then an option would be saving a message as a session attribute, then redirect to your view, recover the session attribute in your view and remove it from session. Remember to always have your user session with only relevant data. Code example

   Controller

   //if request is not from HttpServletRequest, you should do a typecast before
   HttpSession session = request.getSession(false);
   //save message in session
   session.setAttribute("helloWorld", "Hello world");
   response.sendRedirect("/content/test.jsp");
   

   View

   Again, showing this using scriptlets and then EL + JSTL:

   <%
       out.println(session.getAttribute("message"));
       session.removeAttribute("message");
   %>
   
   <c:out value="${sessionScope.message}" />
   <c:remove var="message" scope="session" />

Correlated sub queries are sub queries that depend on the outer query. It’s like a for loop in SQL. The sub-query will run once for each row in the outer query:

select * from users join widgets on widgets.id = (
    select id from widgets
    where widgets.user_id = users.id
    order by created_at desc
    limit 1
)

Download the right whl package for you python version(if you have trouble knowing what version of python you have, just lunch the interpreter )

use pip to install the package, assuming that the file is in downloads folder and you have python 3.6 32 bit :

python -m pip install C:\Users\%USER%\Downloads\cytoolz-0.9.0.1-cp36-cp36m-win32.whl

this is not valid for just this package, but for any package that cannot compile under your own windows installation.

java.io.IOException: Connection reset by peer

In my case, the problem was with PUT requests (GET and POST were passing successfully).

Communication went through VPN tunnel and ssh connection. And there was a firewall with default restrictions on PUT requests... PUT requests haven't been passing throughout, to the server...

Problem was solved after exception was added to the firewall for my IP address.

I solved my problem using some css into the web page.

See ?expression

plot(1:10,main=expression("This is a subscript "[2]))

First, let's clear up some terminology: "asynchronous" (async) means that it may yield control back to the calling thread before it starts. In an async method, those "yield" points are await expressions.

This is very different than the term "asynchronous", as (mis)used by the MSDN documentation for years to mean "executes on a background thread".

To futher confuse the issue, async is very different than "awaitable"; there are some async methods whose return types are not awaitable, and many methods returning awaitable types that are not async.

Enough about what they aren't; here's what they are:

• The async keyword allows an asynchronous method (that is, it allows await expressions). async methods may return Task, Task<T>, or (if you must) void.
• Any type that follows a certain pattern can be awaitable. The most common awaitable types are Task and Task<T>.

So, if we reformulate your question to "how can I run an operation on a background thread in a way that it's awaitable", the answer is to use Task.Run:

private Task<int> DoWorkAsync() // No async because the method does not need await
{
  return Task.Run(() =>
  {
    return 1 + 2;
  });
}

(But this pattern is a poor approach; see below).

But if your question is "how do I create an async method that can yield back to its caller instead of blocking", the answer is to declare the method async and use await for its "yielding" points:

private async Task<int> GetWebPageHtmlSizeAsync()
{
  var client = new HttpClient();
  var html = await client.GetAsync("http://www.example.com/");
  return html.Length;
}

So, the basic pattern of things is to have async code depend on "awaitables" in its await expressions. These "awaitables" can be other async methods or just regular methods returning awaitables. Regular methods returning Task/Task<T> can use Task.Run to execute code on a background thread, or (more commonly) they can use TaskCompletionSource<T> or one of its shortcuts (TaskFactory.FromAsync, Task.FromResult, etc). I don't recommend wrapping an entire method in Task.Run; synchronous methods should have synchronous signatures, and it should be left up to the consumer whether it should be wrapped in a Task.Run:

private int DoWork()
{
  return 1 + 2;
}

private void MoreSynchronousProcessing()
{
  // Execute it directly (synchronously), since we are also a synchronous method.
  var result = DoWork();
  ...
}

private async Task DoVariousThingsFromTheUIThreadAsync()
{
  // I have a bunch of async work to do, and I am executed on the UI thread.
  var result = await Task.Run(() => DoWork());
  ...
}

I have an async/await intro on my blog; at the end are some good followup resources. The MSDN docs for async are unusually good, too.

Worked for me in 30 seconds, short and sweet:

1. In IIS Manager (run inetmgr)
2. Go to ApplicationPool -> Advanced Settings
3. Set ApplicationPoolIdentity to NetworkService
4. Go to the file, right click properties, go to security, click edit, click add, enter Network Service (with space, then click 'check names'), and give full control (or just whatever permissions you need)

I didn't found any particular answer to this question but i deleted the emulator and create a new one and increase the Ram size of the new emulator.Then the emulator works fine.

After some experimentation I found that a fourth value in the line controls the spread (at least in FF 10). I opposed the vertical offsets and gave them a negative spread.

This works perfectly for me!

in my case, I declared one static variable in .h file, like

//myClass.h
class myClass
{
static int m_nMyVar;
static void myFunc();
}

and in myClass.cpp, I tried to use this m_nMyVar. It got LINK error like:

error LNK2001: unresolved external symbol "public: static class... The link error related cpp file looks like:

//myClass.cpp
void myClass::myFunc()
{
myClass::m_nMyVar = 123; //I tried to use this m_nMyVar here and got link error
}

So I add below code on the top of myClass.cpp

//myClass.cpp
int myClass::m_nMyVar; //it seems redefine m_nMyVar, but it works well
void myClass::myFunc()
{
myClass::m_nMyVar = 123; //I tried to use this m_nMyVar here and got link error
}

then LNK2001 is gone.

The I attribute only exists on matrix objects, not ndarrays. You can use numpy.linalg.inv to invert arrays:

inverse = numpy.linalg.inv(x)

Note that the way you're generating matrices, not all of them will be invertible. You will either need to change the way you're generating matrices, or skip the ones that aren't invertible.

try:
    inverse = numpy.linalg.inv(x)
except numpy.linalg.LinAlgError:
    # Not invertible. Skip this one.
    pass
else:
    # continue with what you were doing

Also, if you want to go through all 3x3 matrices with elements drawn from [0, 10), you want the following:

for comb in itertools.product(range(10), repeat=9):

rather than combinations_with_replacement, or you'll skip matrices like

numpy.array([[0, 1, 0],
             [0, 0, 0],
             [0, 0, 0]])

This counts the rows of the inner query:

select count(*) from (
    select count(SID) 
    from Test 
    where Date = '2012-12-10' 
    group by SID
) t

However, in this case the effect of that is the same as this:

select count(distinct SID) from Test where Date = '2012-12-10'

To pass an array of values to any function that normally expects them to be separate parameters, use Function.prototype.apply, so in this case you need:

$.when.apply($, my_array).then( ___ );

See http://jsfiddle.net/YNGcm/21/

In ES6, you can use the ... spread operator instead:

$.when(...my_array).then( ___ );

In either case, since it's unlikely that you'll known in advance how many formal parameters the .then handler will require, that handler would need to process the arguments array in order to retrieve the result of each promise.

I have tried very hard on all the answers above. However, they did not actually help because I used a mac. The rio library has this import function which can basically import any type of data file into Rstudio, even those file using languages other than English!

Try codes below:

    library(rio)
    AB <- import("C:/AB_DNA_Tag_Numbers.xlsx")
    AB <- AB[,1]

Hope this help. For more detailed reference: https://cran.r-project.org/web/packages/rio/vignettes/rio.html

I was missing System.Data.Entity dll reference and problem was solved

One more solution is

Rails.application.routes.routes

Your JRE_HOME does not need to point to the "bin" directory. Just set it to C:\Program Files\Java\jre1.8.0_25

As an alternative which saves from full scanning each table twice and also gives you an easy way to tell which table had more rows with a combination of values than the other:

SELECT col1
     , col2
     -- (include all columns that you want to compare)
     , COUNT(src1) CNT1
     , COUNT(src2) CNT2
  FROM (SELECT a.col1
             , a.col2
             -- (include all columns that you want to compare)
             , 1 src1
             , TO_NUMBER(NULL) src2
          FROM tab_a a
         UNION ALL
        SELECT b.col1
             , b.col2
             -- (include all columns that you want to compare)
             , TO_NUMBER(NULL) src1
             , 2 src2
          FROM tab_b b
       )
 GROUP BY col1
        , col2
HAVING COUNT(src1) <> COUNT(src2) -- only show the combinations that don't match

The operating system takes default shell to run your shell script. so mentioning shell path at the beginning of script, you are asking the OS to use that particular shell. It is also useful for portability.

Simple object hasher:

(function () {
    Number.prototype.toHex = function () {
        var ret = ((this<0?0x8:0)+((this >> 28) & 0x7)).toString(16) + (this & 0xfffffff).toString(16);
        while (ret.length < 8) ret = '0'+ret;
        return ret;
    };
    Object.hashCode = function hashCode(o, l) {
        l = l || 2;
        var i, c, r = [];
        for (i=0; i<l; i++)
            r.push(i*268803292);
        function stringify(o) {
            var i,r;
            if (o === null) return 'n';
            if (o === true) return 't';
            if (o === false) return 'f';
            if (o instanceof Date) return 'd:'+(0+o);
            i=typeof o;
            if (i === 'string') return 's:'+o.replace(/([\\\\;])/g,'\\$1');
            if (i === 'number') return 'n:'+o;
            if (o instanceof Function) return 'm:'+o.toString().replace(/([\\\\;])/g,'\\$1');
            if (o instanceof Array) {
                r=[];
                for (i=0; i<o.length; i++) 
                    r.push(stringify(o[i]));
                return 'a:'+r.join(';');
            }
            r=[];
            for (i in o) {
                r.push(i+':'+stringify(o[i]))
            }
            return 'o:'+r.join(';');
        }
        o = stringify(o);
        for (i=0; i<o.length; i++) {
            for (c=0; c<r.length; c++) {
                r[c] = (r[c] << 13)-(r[c] >> 19);
                r[c] += o.charCodeAt(i) << (r[c] % 24);
                r[c] = r[c] & r[c];
            }
        }
        for (i=0; i<r.length; i++) {
            r[i] = r[i].toHex();
        }
        return r.join('');
    }
}());

The meat here is the stringifier, which simply converts any object into a unique string. hashCode then runs over the object, hashing together the characters of the stringified object.

For extra points, export the stringifier and create a parser.

The install.packages command looks through the .libPaths variable. Here's what mine defaults to on OSX:

> .libPaths()
[1] "/Library/Frameworks/R.framework/Resources/library"

I don't install packages there by default, I prefer to have them installed in my home directory. In my .Rprofile, I have this line:

.libPaths( "/Users/tex/lib/R" )

This adds the directory "/Users/tex/lib/R" to the front of the .libPaths variable.

To convert an int ASCII value to character you can also use:

int asciiValue = 65;
char character = char(asciiValue);
cout << character; // output: A
cout << char(90); // output: Z

It depends on where you're displaying the text. On the console or a textbox for example, \n will suffice. On a RichTextBox I think you need both.

I found this worked best for me.

In AndroidManifest.xml <activity> element add android:windowSoftInputMode="stateHidden"

This always hides the keyboard when entering the activity.

this is how I do it

JAVASCRIPT:

var module = angular.module('yourModuleName', ['ui.router']);

module.run( ['$rootScope', '$state', '$stateParams',
                      function ($rootScope,   $state,   $stateParams) {
    $rootScope.$state = $state;
    $rootScope.$stateParams = $stateParams; 
}
]);

HTML:

<pre id="uiRouterInfo">
      $state = {{$state.current.name}}
      $stateParams = {{$stateParams}}
      $state full url = {{ $state.$current.url.source }}    
</pre>

The Java-based Oracle SQL Developer has a plugin module that supports SQL Server. I use it regularly on my Mac. It's free, too.

Here's how to install the SQL Server plugin:

• Run SQL Developer
• go to this menu item: Oracle SQL Developer/Preferences/Database/Third-party JDBC Drivers
• Click help.
• It will have pointers to the JAR files for MySQL, SQL Server, etc.
• The SQL Server JAR file is available at http://sourceforge.net/projects/jtds/files/

A minimalistic example to quickly test the TTS system:

private TextToSpeech textToSpeechSystem;

@Override
protected void onStart() {
  super.onStart();
  textToSpeechSystem = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
        @Override
        public void onInit(int status) {
            if (status == TextToSpeech.SUCCESS) {
                String textToSay = "Hello world, this is a test message!";
                textToSpeechSystem.speak(textToSay, TextToSpeech.QUEUE_ADD, null);
            }
        }
   });
}

If you don't use localized messages textToSpeechSystem.setLanguage(..) is important as well, since your users probably don't all have English set as their default language so the pronunciation of the words will be wrong. But for testing TTS in general this snippet is enough

Related links: https://developer.android.com/reference/android/speech/tts/TextToSpeech

you can try in this way if you are using thymeleaf

sec:authorize="hasAnyRole(T(com.orsbv.hcs.model.SystemRole).ADMIN.getName(),
               T(com.orsbv.hcs.model.SystemRole).SUPER_USER.getName(),'ROLE_MANAGEMENT')"

this will return true if the user has the mentioned roles,false otherwise.

Please note you have to use sec tag in your html declaration tag like this

<html xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity4">

There isn't really a formal manual, because there's no single style or standard.

So long as you understand the rules of identifier naming you can use whatever you like.

In practice, I find it easier to use lower_case_underscore_separated_identifiers because it isn't necessary to "Double Quote" them everywhere to preserve case, spaces, etc.

If you wanted to name your tables and functions "@MyA??! ""betty"" Shard$42" you'd be free to do that, though it'd be pain to type everywhere.

The main things to understand are:

• Unless double-quoted, identifiers are case-folded to lower-case, so MyTable, MYTABLE and mytable are all the same thing, but "MYTABLE" and "MyTable" are different;

• Unless double-quoted:

  SQL identifiers and key words must begin with a letter (a-z, but also letters with diacritical marks and non-Latin letters) or an underscore (_). Subsequent characters in an identifier or key word can be letters, underscores, digits (0-9), or dollar signs ($).

• You must double-quote keywords if you wish to use them as identifiers.

In practice I strongly recommend that you do not use keywords as identifiers. At least avoid reserved words. Just because you can name a table "with" doesn't mean you should.

I tried making changes to Intellij IDEA as below:

1.

File >> Settings >> Build, Execution, Deployment >> Compiler >> Java Compiler >> project bytecode version: 1.8 >> Per-module bytecode version: 1.8

2.

File >> Project Structure >> Project Settings >> Project >> SDK : 1.8, Project Language : 8 - Lambdas
File >> Project Structure >> Project Settings >> Modules >> abc : Language level: 8 - Lambdas

but nothing worked, it reverted the versions to java 1.5 as soon as I saved it.

However, adding below lines to root(project level) pom.xml worked me to resolve above issue: (both of the options worked for me)

Option 1:

<properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

Option 2:

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
        </plugin>
    </plugins>
</build>

Let me quote this:

Hibernate created a new language named Hibernate Query Language (HQL), the syntax is quite similar to database SQL language. The main difference between is HQL uses class name instead of table name, and property names instead of column name.

As far as I can see you are using the table name.

So it should be like this:

Query query = session.createQuery("from Employee");

The answer is no.

Incorrect

.class {
    background-color: none; /* do not do this */
}

Correct

.class {
    background-color: transparent;
}

background-color: transparent accomplishes the same thing what you wanted to do with background-color: none.

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

REST

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

SOAP

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

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

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

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

"In the default mode, Dot (.) matches any character except a newline. If the DOTALL flag has been specified, this matches any character including a newline." (python Doc)

So, if you want to evaluate dot literaly, I think you should put it in square brackets:

>>> p = re.compile(r'\b(\w+[.]\w+)')
>>> resp = p.search("blah blah blah [email protected] blah blah")
>>> resp.group()
'test.this'

I know it's way too late to answer this question, but I'll just post the solution that worked for me, in case someone runs into trouble again in the future.

I tried using genymotion's own adb tools and the original Android SDK ones, and even purging and reinstalling adb from my system, but nothing worked. I kept getting the error:

adb server is out of date. killing... cannot bind 'tcp:5037' ADB server didn't ACK *failed to start daemon* error:
So I tried adb connect [ip] as suggested here, but I didn't work either, the same error came up.

What finally worked for me was downloading ADT, and running adb directly from the downloaded folder, instead of the system-wide command. So adb devices will give me the error above, but /yourdownloadpath/adb devices works just fine for me.

Hope it helped.

I don't Know you use any Bootstrap version but the useful helper class for centering and block an element in center it is .center-block because this class contain margin and display CSS properties but the .text-center class only contain the text-align property

You have the wrong URL.

I don't know what you mean by "JDBC 2005". When I looked on the microsoft site, I found something called the Microsoft SQL Server JDBC Driver 2.0. You're going to want that one - it includes lots of fixes and some perf improvements. [edit: you're probably going to want the latest driver. As of March 2012, the latest JDBC driver from Microsoft is JDBC 4.0]

Check the release notes. For this driver, you want:

URL:  jdbc:sqlserver://server:port;DatabaseName=dbname
Class name: com.microsoft.sqlserver.jdbc.SQLServerDriver

It seems you have the class name correct, but the URL wrong.

Microsoft changed the class name and the URL after its initial release of a JDBC driver. The URL you are using goes with the original JDBC driver from Microsoft, the one MS calls the "SQL Server 2000 version". But that driver uses a different classname.

For all subsequent drivers, the URL changed to the form I have here.

This is in the release notes for the JDBC driver.

A bit more readable and simple approach could be achieved with the script below:

$Directory = "./"
Get-ChildItem $Directory -Recurse | % {
    if ($_.Attributes -eq "Directory") {
        Write-Host $_.FullName
    }
}

Hope this helps!

had the same issue lost hours trying to install different version of python on my PC. Simply Upgrade node to the latest version v8.11.2 and npm 5.6.0, then after install [email protected] and you'll be fine.

Those of us using Python 3.x should do this:

python -c "import sys; print(sys.path)"

//start the program
var express = require('express');
var app = express();

app.get('/', function (req, res) {

    var sql = require("mssql");

    // config for your database
    var config = {
        user: 'datapullman',
        password: 'system',
        server: 'localhost', 
        database: 'chat6' 
    };

    // connect to your database
    sql.connect(config, function (err) {

        if (err) console.log(err);

        // create Request object
        var request = new sql.Request();

        // query to the database and get the records

        request.query("select * From emp", function (err, recordset) {            
            if  (err) console.log(err)

            // send records as a response
            res.send(recordset);

        });
    });
});

var server = app.listen(5000, function () {
    console.log('Server is running..');
});

//create a table as emp in a database (i have created as chat6)

// programs ends here

//save it as app.js and run as node app.js //open in you browser as localhost:5000

You can do in the following case,

CREATE PROCEDURE spDoSearch
   @FirstName varchar(25) = null,
   @LastName varchar(25) = null,
   @Title varchar(25) = null
AS
  BEGIN
      SELECT ID, FirstName, LastName, Title
      FROM tblUsers
      WHERE
        (@FirstName IS NULL OR FirstName = @FirstName) AND
        (@LastNameName IS NULL OR LastName = @LastName) AND
        (@Title IS NULL OR Title = @Title)
END

however depend on data sometimes better create dynamic query and execute them.

From page 106 of the ggplot2 book by Hadley Wickham:

The default colour scheme, scale_colour_hue picks evenly spaced hues around the hcl colour wheel.

With a bit of reverse engineering you can construct this function:

ggplotColours <- function(n = 6, h = c(0, 360) + 15){
  if ((diff(h) %% 360) < 1) h[2] <- h[2] - 360/n
  hcl(h = (seq(h[1], h[2], length = n)), c = 100, l = 65)
}

Demonstrating this in barplot:

y <- 1:3
barplot(y, col = ggplotColours(n = 3))

The TensorFlow package couldn't be found by the latest version of the "pip".
To be honest, I really don't know why this is...
but, the quick fix that worked out for me was:
[In case you are using a virtual environment]
downgrade the virtual environment to python-3.8.x and pip-20.2.x In case of anaconda, try:

conda install python=3.8

This should install the latest version of python-3.8 and pip-20.2.x for you.
And then, try

pip install tensorflow

Again, this worked fine for me, not sure if it'll work the same for you.

Late answer but adding so other can learn the reason.

You also need to edit the php.ini file in the "wamp\bin\php\php-X.Y.Z" location.

You can use ng-class to add conditional classes.

HTML

<button id="button1" ng-click="alpha = true" ng-class="{alpha: alpha}">Button</button>

In your controller (to make sure the class is not shown by default)

$scope.alpha = false;

Now, when you click the button, the $scope.alpha variable is updated and ng-class will add the 'alpha' class to your button.

I found the accepted solution didn't work on my MySQL install, returning an empty set, but this query worked for me in all situations that I tested it on:

SELECT x.val from data x, data y
GROUP BY x.val
HAVING SUM(SIGN(1-SIGN(y.val-x.val)))/COUNT(*) > .5
LIMIT 1

1. Extract the package to C:\ from here and install it

2. Copy the path C:\MinGW\bin which contains gcc.exe.

3. go to Control Panel->System->Advanced>Environment variables, and add or modify PATH. (just concatenate with ';')

4. Then, open a cmd.exe command prompt (Windows + R and type cmd, if already opened, please close and open a new one, to get the path change)

5. change the folder to your file path by cd D:\c code Path

6. type gcc main.c -o helloworld.o. It will compile the code. for C++ use g++

7 type ./helloworld to run the program.

Solution using just POST - no $_SESSION

page1.php

<form action="page2.php" method="post">
    <textarea name="textarea1" id="textarea1"></textarea><br />
    <input type="submit" value="submit" />
</form>

page2.php

<?php
    // this page outputs the contents of the textarea if posted
    $textarea1 = ""; // set var to avoid errors
    if(isset($_POST['textarea1'])){
        $textarea1 = $_POST['textarea1']
    }
?>
<textarea><?php echo $textarea1;?></textarea>

Solution using $_SESSION and POST

page1.php

<?php

    session_start(); // needs to be before anything else on page to use $_SESSION
    $textarea1 = "";
    if(isset($_POST['textarea1'])){
        $_SESSION['textarea1'] = $_POST['textarea1'];
    }

?>


<form action="page1.php" method="post">
    <textarea name="textarea1" id="textarea1"></textarea><br />
    <input type="submit" value="submit" />
</form>
<br /><br />
<a href="page2.php">Go to page2</a>

page2.php

<?php
    session_start(); // needs to be before anything else on page to use $_SESSION
    // this page outputs the textarea1 from the session IF it exists
    $textarea1 = ""; // set var to avoid errors
    if(isset($_SESSION['textarea1'])){
        $textarea1 = $_SESSION['textarea1']
    }
?>
<textarea><?php echo $textarea1;?></textarea>

WARNING!!! - This contains no validation!!!

You mean this?

from string import punctuation, digits

takeout = punctuation + digits

turnthis = "(fjskl) 234 = -345 089 abcdef"
turnthis = turnthis.translate(None, takeout)[::-1]
print turnthis

It works fine with the object literal notation:

var map = { key : { "aaa", "rrr" }, 
            key2: { "bbb", "ppp" } // trailing comma leads to syntax error in IE!
          }

Btw, the common way to instantiate arrays

var array = [];
// directly with values:
var array = [ "val1", "val2", 3 /*numbers may be unquoted*/, 5, "val5" ];

and objects

var object = {};

Also you can do either:

obj.property     // this is prefered but you can also do
obj["property"]  // this is the way to go when you have the keyname stored in a var

var key = "property";
obj[key] // is the same like obj.property

This function will validate the date to see if it's correct or if it's in the proper format of: DD/MM/YYYY.

function isValidDate(date)
{
    var matches = /^(\d{2})[-\/](\d{2})[-\/](\d{4})$/.exec(date);
    if (matches == null) return false;
    var d = matches[1];
    var m = matches[2]-1;
    var y = matches[3];
    var composedDate = new Date(y, m, d);
    return composedDate.getDate() == d &&
           composedDate.getMonth() == m &&

As you said, in MySQL USAGE is synonymous with "no privileges". From the MySQL Reference Manual:

The USAGE privilege specifier stands for "no privileges." It is used at the global level with GRANT to modify account attributes such as resource limits or SSL characteristics without affecting existing account privileges.

USAGE is a way to tell MySQL that an account exists without conferring any real privileges to that account. They merely have permission to use the MySQL server, hence USAGE. It corresponds to a row in the `mysql`.`user` table with no privileges set.

The IDENTIFIED BY clause indicates that a password is set for that user. How do we know a user is who they say they are? They identify themselves by sending the correct password for their account.

A user's password is one of those global level account attributes that isn't tied to a specific database or table. It also lives in the `mysql`.`user` table. If the user does not have any other privileges ON *.*, they are granted USAGE ON *.* and their password hash is displayed there. This is often a side effect of a CREATE USER statement. When a user is created in that way, they initially have no privileges so they are merely granted USAGE.

@slebetmen's accepted answer explains well why this doesn't work. In addition to the two patterns presented in that answer, another option is to only access your async properties through a custom async getter. The constructor() can then trigger the async creation of the properties, but the getter then checks to see if the property is available before it uses or returns it.

This approach is particularly useful when you want to initialize a global object once on startup, and you want to do it inside a module. Instead of initializing in your index.js and passing the instance in the places that need it, simply require your module wherever the global object is needed.

Usage

const instance = new MyClass();
const prop = await instance.getMyProperty();

Implementation

class MyClass {
  constructor() {
    this.myProperty = null;
    this.myPropertyPromise = this.downloadAsyncStuff();
  }
  async downloadAsyncStuff() {
    // await yourAsyncCall();
    this.myProperty = 'async property'; // this would instead by your async call
    return this.myProperty;
  }
  getMyProperty() {
    if (this.myProperty) {
      return this.myProperty;
    } else {
      return this.myPropertyPromise;
    }
  }
}

But you can open the folder with the .SLN in to edit the code in the project, which will detect the .SLN to select the library that provides Intellisense.

It specifies the size of the log file to trigger rotation. For example size 50M will trigger a log rotation once the file is 50MB or greater in size. You can use the suffix M for megabytes, k for kilobytes, and G for gigabytes. If no suffix is used, it will take it to mean bytes. You can check the example at the end. There are three directives available size, maxsize, and minsize. According to manpage:

minsize size
              Log  files  are  rotated when they grow bigger than size bytes,
              but not before the additionally specified time interval (daily,
              weekly,  monthly, or yearly).  The related size option is simi-
              lar except that it is mutually exclusive with the time interval
              options,  and  it causes log files to be rotated without regard
              for the last rotation time.  When minsize  is  used,  both  the
              size and timestamp of a log file are considered.

size size
              Log files are rotated only if they grow bigger then size bytes.
              If size is followed by k, the size is assumed to  be  in  kilo-
              bytes.  If the M is used, the size is in megabytes, and if G is
              used, the size is in gigabytes. So size 100,  size  100k,  size
              100M and size 100G are all valid.
maxsize size
              Log files are rotated when they grow bigger than size bytes even before
              the additionally specified time interval (daily, weekly, monthly, 
              or yearly).  The related size option is  similar  except  that  it 
              is mutually exclusive with the time interval options, and it causes
              log files to be rotated without regard for the last rotation time.  
              When maxsize is used, both the size and timestamp of a log file are                  
              considered.

Here is an example:

"/var/log/httpd/access.log" /var/log/httpd/error.log {
           rotate 5
           mail [email protected]
           size 100k
           sharedscripts
           postrotate
               /usr/bin/killall -HUP httpd
           endscript
       }

Here is an explanation for both files /var/log/httpd/access.log and /var/log/httpd/error.log. They are rotated whenever it grows over 100k in size, and the old logs files are mailed (uncompressed) to [email protected] after going through 5 rotations, rather than being removed. The sharedscripts means that the postrotate script will only be run once (after the old logs have been compressed), not once for each log which is rotated. Note that the double quotes around the first filename at the beginning of this section allows logrotate to rotate logs with spaces in the name. Normal shell quoting rules apply, with ,, and \ characters supported.

Promise:

• Provide a single future value;
• Not lazy;
• Not cancellable;

Observable:

• Emits multiple values over time;
• Lazy;
• Cancellable;
• Supports map, filter, reduce and similar operators

You can use promises instead of observables when calling HTTP in Angular if you wish.

CASE course_enrollment_settings.base_price is wrong here, it should be just CASE

SELECT 
CASE 
WHEN course_enrollment_settings.base_price = 0      THEN 1 
WHEN course_enrollment_settings.base_price<101      THEN 2 
WHEN course_enrollment_settings.base_price>100 AND    
                  course_enrollment_settings.base_price<201 THEN 3 
    ELSE 6 
END AS 'calc_base_price', 
course_enrollment_settings.base_price 
FROM 
  course_enrollment_settings 
WHERE course_enrollment_settings.base_price = 0 

Some explanations. Your original query will be executed as :

SELECT 
CASE 0
WHEN 0=0 THEN 1 -- condition evaluates to 1, then 0 (from CASE 0)compares to 1 - false
WHEN 0<1 THEN 2 -- condition evaluates to 1,then 0 (from CASE 0)compares to 1 - false
WHEN 0>100 and 0<201 THEN 3 -- evaluates to 0 ,then 0 (from CASE 0)compares to 0 - true
ELSE 6, ...

it's why you always get 3

This is a really unclear and unhelpful error message. After much trial and error I found that LocalDateTime will give the above error if you do not attempt to parse a time. By using LocalDate instead, it works without erroring.

This is poorly documented and the related exception is very unhelpful.

Why would UPDLOCK block selects? The Lock Compatibility Matrix clearly shows N for the S/U and U/S contention, as in No Conflict.

As for the HOLDLOCK hint the documentation states:

HOLDLOCK: Is equivalent to SERIALIZABLE. For more information, see SERIALIZABLE later in this topic.

...

SERIALIZABLE: ... The scan is performed with the same semantics as a transaction running at the SERIALIZABLE isolation level...

and the Transaction Isolation Level topic explains what SERIALIZABLE means:

No other transactions can modify data that has been read by the current transaction until the current transaction completes.

Other transactions cannot insert new rows with key values that would fall in the range of keys read by any statements in the current transaction until the current transaction completes.

Therefore the behavior you see is perfectly explained by the product documentation:

• UPDLOCK does not block concurrent SELECT nor INSERT, but blocks any UPDATE or DELETE of the rows selected by T1
• HOLDLOCK means SERALIZABLE and therefore allows SELECTS, but blocks UPDATE and DELETES of the rows selected by T1, as well as any INSERT in the range selected by T1 (which is the entire table, therefore any insert).
• (UPDLOCK, HOLDLOCK): your experiment does not show what would block in addition to the case above, namely another transaction with UPDLOCK in T2:
  SELECT * FROM dbo.Test WITH (UPDLOCK) WHERE ...
• TABLOCKX no need for explanations

The real question is what are you trying to achieve? Playing with lock hints w/o an absolute complete 110% understanding of the locking semantics is begging for trouble...

After OP edit:

I would like to select rows from a table and prevent the data in that table from being modified while I am processing it.

The you should use one of the higher transaction isolation levels. REPEATABLE READ will prevent the data you read from being modified. SERIALIZABLE will prevent the data you read from being modified and new data from being inserted. Using transaction isolation levels is the right approach, as opposed to using query hints. Kendra Little has a nice poster exlaining the isolation levels.

Simple as this: <input type="text" name="email" value="e-mail..." onFocus="this.value=''">

A one-line version of this excellent answer to plot the line of best fit is:

plt.plot(np.unique(x), np.poly1d(np.polyfit(x, y, 1))(np.unique(x)))

Using np.unique(x) instead of x handles the case where x isn't sorted or has duplicate values.

The call to poly1d is an alternative to writing out m*x + b like in this other excellent answer.

This is how i registered my domain:

sudo letsencrypt --apache -d mydomain.com

Then it was possible to use the same command with additional domains and follow the instructions:

sudo letsencrypt --apache -d mydomain.com,x.mydomain.com,y.mydomain.com

I had this problem with a SOA system written in Java. I was running both the client and the server on different physical machines and they worked fine for a long time, then those nasty connection resets appeared in the client log and there wasn't anything strange in the server log. Restarting both client and server didn't solve the problem. Finally we discovered that the heap on the server side was rather full so we increased the memory available to the JVM: problem solved! Note that there was no OutOfMemoryError in the log: memory was just scarce, not exhausted.

You should re-assign the result of the replacement, like this:

 sentence = sentence.replace("and", " ");

Be aware that the String class is immutable, meaning that all of its methods return a new string and never modify the original string in-place, so the result of invoking a method in an instance of String must be assigned to a variable or used immediately for the change to take effect.

The answer is yes. In short, it is a subject alternative name (SAN) certificate that contains IPs where you would typically see DNS entries. The certificate type is not limited to Public IPs - that restriction is only imposed by a signing authority rather than the technology. I just wanted to clarify that point. I suspect you really just want to get rid of that pesky insecure prompt on your internal websites and devices without the cost and hassle of giving them DNS names then paying for a CA to issue a cert every year or two. You should NOT be trying to convince the world that your IP address is a reputable website and folks should feel comfortable providing their payment information. Now that we have established why no reputable organization wants to issue this type of certificate, lets just do it ourselves with a self signed SAN certificate. Internally I have a trusted certificate that is deployed to all of our hosts, then I sign this type of certificate with it and all devices become trusted. Doing that here is beyond the scope of the question but I think it relevant to the discussion as the question and solution go hand in hand. To be concise, here is how to generate an individual self signed SAN certificate with IP addresses. Expand the IP list to include your entire subnet and use one cert for everything.

Use double braces {{ or }} so your code becomes:

sb.AppendLine(String.Format("public {0} {1} {{ get; private set; }}", 
prop.Type, prop.Name));

// For prop.Type of "Foo" and prop.Name of "Bar", the result would be:
// public Foo Bar { get; private set; }

Although a strict, logical, computer science'ish interpretation of the op's question would be to require both "How do I retrieve my MySQL username" and "password" - I thought It might be useful to someone to also address the OR interpretation. In other words ...

1) How do I retrieve my MySQL username?

OR

2) password

This latter condition seems to have been amply addressed already so I won't bother with it. The following is a solution for the case "How do i retreive my MySQL username" alone. HIH.

To find your mysql username run the following commands from the mysql shell ...

SELECT User FROM mysql.user;

it will print a table of all mysql users.

I will add my upgraded version of filter which able to supports next syntax:

ng-repeat="(id, item) in $ctrl.modelData | orderObjectBy:'itemProperty.someOrder':'asc'

app.filter('orderObjectBy', function(){

         function byString(o, s) {
            s = s.replace(/\[(\w+)\]/g, '.$1'); // convert indexes to properties
            s = s.replace(/^\./, '');           // strip a leading dot
            var a = s.split('.');
            for (var i = 0, n = a.length; i < n; ++i) {
                var k = a[i];
                if (k in o) {
                    o = o[k];
                } else {
                    return;
                }
            }
            return o;
        }

        return function(input, attribute, direction) {
            if (!angular.isObject(input)) return input;

            var array = [];
            for(var objectKey in input) {
                if (input.hasOwnProperty(objectKey)) {
                    array.push(input[objectKey]);
                }
            }

            array.sort(function(a, b){
                a = parseInt(byString(a, attribute));
                b = parseInt(byString(b, attribute));
                return direction == 'asc' ? a - b : b - a;
            });
            return array;
        }

Thanks to Armin and Jason for their answers in this thread, and Alnitak in this thread.

I had the same problem.

I had to print the color of the nodes where the color was: enum col { WHITE, GRAY, BLACK }; and the node: typedef struct Node { col color; };

I tried to print node->color with printf("%s\n", node->color); but all I got on the screen was (null)\n.

The answer bmargulies gave almost solved the problem.

So my final solution is:

static char *enumStrings[] = {"WHITE", "GRAY", "BLACK"};
printf("%s\n", enumStrings[node->color]);

Try this out. Hope this helps

<div id="single" dir="rtl">
    <div class="common">Single</div>
</div>

<div id="both" dir="ltr">
    <div class="common">Both</div>

#single, #both{
    width: 100px;
    height: 100px;
    overflow: auto;
    margin: 0 auto;
    border: 1px solid gray;
}


.common{
    height: 150px;
    width: 150px;

Check out Regular Expressions.

You should probably do some validations before you actually execute your function :

function trim(str) {
    if(typeof str !== 'string') {
        throw new Error('only string parameter supported!');
    }

    return str.replace(/^\s+|\s+$/g,'');
}

Use a BindingList and set the DataPropertyName-Property of the column.

Try the following:

...
private void BindGrid()
{
    gvFilesOnServer.AutoGenerateColumns = false;

    //create the column programatically
    DataGridViewCell cell = new DataGridViewTextBoxCell();
    DataGridViewTextBoxColumn colFileName = new DataGridViewTextBoxColumn()
    {
        CellTemplate = cell, 
        Name = "Value",
        HeaderText = "File Name",
        DataPropertyName = "Value" // Tell the column which property of FileName it should use
     };

    gvFilesOnServer.Columns.Add(colFileName);

    var filelist = GetFileListOnWebServer().ToList();
    var filenamesList = new BindingList<FileName>(filelist); // <-- BindingList

    //Bind BindingList directly to the DataGrid, no need of BindingSource
    gvFilesOnServer.DataSource = filenamesList 
}

I have case to have some bottom border between pictures in div container and the best one line code was - border-bottom-style: inset;

Thou the above answer is widely accepted and well documented, I found some of the reason to post my answer here :-

    doNothing().when(InternalUtils.class); //This is the preferred way
                                           //to mock static void methods.
    InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());

Here, I dont understand why we are calling InternalUtils.sendEmail ourself. I will explain in my code why we don't need to do that.

mockStatic(Internalutils.class);

So, we have mocked the class which is fine. Now, lets have a look how we need to verify the sendEmail(/..../) method.

@PrepareForTest({InternalService.InternalUtils.class})
@RunWith(PowerMockRunner.class)
public class InternalServiceTest {

    @Mock
    private InternalService.Order order;

    private InternalService internalService;

    @Before
    public void setup() {
        MockitoAnnotations.initMocks(this);
        internalService = new InternalService();
    }

    @Test
    public void processOrder() throws Exception {

        Mockito.when(order.isSuccessful()).thenReturn(true);
        PowerMockito.mockStatic(InternalService.InternalUtils.class);

        internalService.processOrder(order);

        PowerMockito.verifyStatic(times(1));
        InternalService.InternalUtils.sendEmail(anyString(), any(String[].class), anyString(), anyString());
    }

}

These two lines is where the magic is, First line tells the PowerMockito framework that it needs to verify the class it statically mocked. But which method it need to verify ?? Second line tells which method it needs to verify.

PowerMockito.verifyStatic(times(1));
InternalService.InternalUtils.sendEmail(anyString(), any(String[].class), anyString(), anyString());

This is code of my class, sendEmail api twice.

public class InternalService {

    public void processOrder(Order order) {
        if (order.isSuccessful()) {
            InternalUtils.sendEmail("", new String[1], "", "");
            InternalUtils.sendEmail("", new String[1], "", "");
        }
    }

    public static class InternalUtils{

        public static void sendEmail(String from, String[]  to, String msg, String body){

        }

    }

    public class Order{

        public boolean isSuccessful(){
            return true;
        }

    }

}

As it is calling twice you just need to change the verify(times(2))... that's all.

There's a .val() method:

If you've got an input with an id of txtEmail you can use the following code to access the value of the text box:

$("#txtEmail").val()

You can also use the val(string) method to set that value:

$("#txtEmail").val("something")

I have had to do this for a small Node.js project and found this work-around:

{
 "modify_head": [

  "<script type='text/javascript'>",
  "<!--",
  "  function drawSomeText(id) {",
  "  var pjs = Processing.getInstanceById(id);",
  "  var text = document.getElementById('inputtext').value;",
  "  pjs.drawText(text);}",
  "-->",
  "</script>"

 ],

 "modify_body": [

  "<input type='text' id='inputtext'></input>",
  "<button onclick=drawSomeText('ExampleCanvas')></button>"

 ],
}

This looks quite neat to me, appart from that I have to use double quotes everywhere. Though otherwise, I could, perhaps, use YAML, but that has other pitfalls and is not supported natively. Once parsed, I just use myData.modify_head.join('\n') or myData.modify_head.join(), depending upon whether I want a line break after each string or not.

Taking care of whether the array starts at zero or one. Also, when position 0 or 1 is returned by the function, making sure that the same is not confused as True or False returned by the function.

Function array_return_index(arr As Variant, val As Variant, Optional array_start_at_zero As Boolean = True) As Variant

Dim pos
pos = Application.Match(val, arr, False)

If Not IsError(pos) Then
    If array_start_at_zero = True Then
        pos = pos - 1
        'initializing array at 0
    End If
   array_return_index = pos
Else
   array_return_index = False
End If

End Function

Sub array_return_index_test()
Dim pos, arr, val

arr = Array(1, 2, 4, 5)
val = 1

'When array starts at zero
pos = array_return_index(arr, val)
If IsNumeric(pos) Then
MsgBox "Array starting at 0; Value found at : " & pos
Else
MsgBox "Not found"
End If

'When array starts at one
pos = array_return_index(arr, val, False)
If IsNumeric(pos) Then
MsgBox "Array starting at 1; Value found at : " & pos
Else
MsgBox "Not found"
End If



End Sub

If the machine you are on is part of the AD domain, it should have its name servers set to the AD name servers (or hopefully use a DNS server path that will eventually resolve your AD domains). Using your example of dc=domain,dc=com, if you look up domain.com in the AD name servers it will return a list of the IPs of each AD Controller. Example from my company (w/ the domain name changed, but otherwise it's a real example):

    mokey 0 /home/jj33 > nslookup example.ad
    Server:         172.16.2.10
    Address:        172.16.2.10#53

    Non-authoritative answer:
    Name:   example.ad
    Address: 172.16.6.2
    Name:   example.ad
    Address: 172.16.141.160
    Name:   example.ad
    Address: 172.16.7.9
    Name:   example.ad
    Address: 172.19.1.14
    Name:   example.ad
    Address: 172.19.1.3
    Name:   example.ad
    Address: 172.19.1.11
    Name:   example.ad
    Address: 172.16.3.2

Note I'm actually making the query from a non-AD machine, but our unix name servers know to send queries for our AD domain (example.ad) over to the AD DNS servers.

I'm sure there's a super-slick windowsy way to do this, but I like using the DNS method when I need to find the LDAP servers from a non-windows server.

Wes McKinney (pandas' author) in Python for Data Analysis provides the following recipe:

groups = dict(list(gb))

which returns a dictionary whose keys are your group labels and whose values are DataFrames, i.e.

groups['foo']

will yield what you are looking for:

     A         B   C
0  foo  1.624345   5
2  foo -0.528172  11
4  foo  0.865408  14

I often need to run an X command on a server that is running many X servers, so the ps based answers do not work. Naturally, $DISPLAY has to be set appropriately. To check that that is valid, use xset q in some fragment like:

if ! xset q &>/dev/null; then
    echo "No X server at \$DISPLAY [$DISPLAY]" >&2
    exit 1
fi

EDIT

Some people find that xset can pause for a annoying amount of time before deciding that $DISPLAY is not pointing at a valid X server (often when tcp/ip is the transport). The fix of course is to use timeout to keep the pause amenable, 1 second say.

if ! timeout 1s xset q &>/dev/null; then
    ?

npm install bootstrap jquery --save

You don't have to install popper.js with npm as it comes with npm Bootstrap in bootstrap.bundle.js.

Bundled JS files (bootstrap.bundle.js and minified bootstrap.bundle.min.js) include Popper, but not jQuery.

Source to Verify: Link

Now you only have to do this in your HTML file:

<script src="node_modules/jquery/dist/jquery.slim.min.js"></script>
<script src="node_modules/bootstrap/dist/js/bootstrap.bundle.min.js"></script>
<script src="node_modules/bootstrap/dist/js/bootstrap.min.js"></script>

You can pass array of variables to the compact as an arguement eg:

return view('yourView', compact(['var1','var2',....'varN']));

in view: if var1 is an object you can use it something like this

@foreach($var1 as $singleVar1)
    {{$singleVar1->property}}
@endforeach

incase of single variable you can simply

"Any CPU" means that when the program is started, the .NET Framework will figure out, based on the OS bitness, whether to run your program in 32 bits or 64 bits.

There is a difference between x86 and Any CPU: on a x64 system, your executable compiled for X86 will run as a 32-bit executable.

As far as your suspicions go, just go to the Visual Studio 2008 command line and run the following.

dumpbin YourProgram.exe /headers

It will tell you the bitness of your program, plus a whole lot more.

Use stri_sub function from stringi package. To get substring from the end, use negative numbers. Look below for the examples:

stri_sub("abcde",1,3)
[1] "abc"
stri_sub("abcde",1,1)
[1] "a"
stri_sub("abcde",-3,-1)
[1] "cde"

You can install this package from github: https://github.com/Rexamine/stringi

It is available on CRAN now, simply type

install.packages("stringi")

to install this package.

The party's pretty much dead now, but here's an "improved" version of user166390 that made its way into my extension library. Apart from some details, I added a delegate to calculate the merged value.

/// <summary>
/// Merges a dictionary against an array of other dictionaries.
/// </summary>
/// <typeparam name="TResult">The type of the resulting dictionary.</typeparam>
/// <typeparam name="TKey">The type of the key in the resulting dictionary.</typeparam>
/// <typeparam name="TValue">The type of the value in the resulting dictionary.</typeparam>
/// <param name="source">The source dictionary.</param>
/// <param name="mergeBehavior">A delegate returning the merged value. (Parameters in order: The current key, The current value, The previous value)</param>
/// <param name="mergers">Dictionaries to merge against.</param>
/// <returns>The merged dictionary.</returns>
public static TResult MergeLeft<TResult, TKey, TValue>(
    this TResult source,
    Func<TKey, TValue, TValue, TValue> mergeBehavior,
    params IDictionary<TKey, TValue>[] mergers)
    where TResult : IDictionary<TKey, TValue>, new()
{
    var result = new TResult();
    var sources = new List<IDictionary<TKey, TValue>> { source }
        .Concat(mergers);

    foreach (var kv in sources.SelectMany(src => src))
    {
        TValue previousValue;
        result.TryGetValue(kv.Key, out previousValue);
        result[kv.Key] = mergeBehavior(kv.Key, kv.Value, previousValue);
    }

    return result;
}

• In Python, you wouldn't use indexes for this at all, but just deal with the values—[value for value in a if value > 2]. Usually dealing with indexes means you're not doing something the best way.

• If you do need an API similar to Matlab's, you would use numpy, a package for multidimensional arrays and numerical math in Python which is heavily inspired by Matlab. You would be using a numpy array instead of a list.

  >>> import numpy
  >>> a = numpy.array([1, 2, 3, 1, 2, 3])
  >>> a
  array([1, 2, 3, 1, 2, 3])
  >>> numpy.where(a > 2)
  (array([2, 5]),)
  >>> a > 2
  array([False, False,  True, False, False,  True], dtype=bool)
  >>> a[numpy.where(a > 2)]
  array([3, 3])
  >>> a[a > 2]
  array([3, 3])
  

From the PHP Manual:

Warning This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide. Alternatives to this function include:

mysqli_connect()

PDO::__construct()

use MySQLi or PDO

<?php
$con = mysqli_connect('localhost', 'username', 'password', 'database');

If you need to find database objects (e.g. tables, columns, triggers) by name - have a look at the FREE Red-Gate tool called SQL Search which does this - it searches your entire database for any kind of string(s).

It's a great must-have tool for any DBA or database developer - did I already mention it's absolutely FREE to use for any kind of use??

Use a pattern along these lines:

function getValue(file) {
  return lookupValue(file);
}

getValue('myFile.txt').then(function(res) {
  // do whatever with res here
});

(although this is a bit redundant, I'm sure your actual code is more complicated)

res = ActiveRecord::Base.connection_pool.with_connection { |con| con.exec_query( "SELECT 1;" ) }

The above code is an example for

1. executing arbitrary SQL on your database-connection
2. returning the connection back to the connection pool afterwards

It has to be a constant - the value has to be computable at the time that the procedure is created, and that one computation has to provide the value that will always be used.

Look at the definition of sys.all_parameters:

default_value sql_variant If has_default_value is 1, the value of this column is the value of the default for the parameter; otherwise, NULL.

That is, whatever the default for a parameter is, it has to fit in that column.

As Alex K pointed out in the comments, you can just do:

CREATE PROCEDURE [dbo].[problemParam] 
    @StartDate INT = NULL,
    @EndDate INT = NULL
AS  
BEGIN
   SET @StartDate = COALESCE(@StartDate,CONVERT(INT,(CONVERT(CHAR(8),GETDATE()-130,112))))

provided that NULL isn't intended to be a valid value for @StartDate.

As to the blog post you linked to in the comments - that's talking about a very specific context - that, the result of evaluating GETDATE() within the context of a single query is often considered to be constant. I don't know of many people (unlike the blog author) who would consider a separate expression inside a UDF to be part of the same query as the query that calls the UDF.

supportActionBar?.title = "Hola tio"
supportActionBar?.subtitle = "Vamos colega!"

If a non-static method is member of a class, you have to define it like that:

def Method(self, atributes..)

So, I suppose your 'e' is instance of some class with implemented method that tries to execute and has too much arguments.

1. Launch Terminal
2. Type -> nano fileName
3. Paste Batch file content and save it
4. Type -> chmod +x fileName
5. It will create exe file now you can double click and it.

File name should in under double quotes. Since i am using Mac->In my case content of batch file is

cd /Users/yourName/Documents/SeleniumServer

java -jar selenium-server-standalone-3.3.1.jar -role hub

It will work for sure

Open notepad and paste this code:

@echo off
powershell -Command "Start-Process cmd -Verb RunAs -ArgumentList '/c cd /d %CD% && %*'"
@echo on

Then, save the file as sudo.cmd. Copy this file and paste it at C:\Windows\System32 or add the path where sudo.cmd is to your PATH Environment Variable.

When you open command prompt, you can now run something like sudo start ..

If you want the admin command prompt window to stay open when you run the command, change the code in notepad to this:

@echo off
powershell -Command "Start-Process cmd -Verb RunAs -ArgumentList '/k cd /d %CD% && %*'"
@echo on

Explanation:

powershell -Command runs a powershell command.

Start-Process is a powershell command that starts a process, in this case, command prompt.

-Verb RunAs runs the command as admin.

-Argument-List runs the command with arguments.

Our arguments are '/c cd /d %CD% && %*'. %* means all arguments, so if you did sudo foo bar, it would run in command prompt foo bar because the parameters are foo and bar, and %* returns foo bar. cd /d %CD% is a command to go to the current directory. This will ensure that when you open the elevated window, the directory will be the same as the normal window. the && means that if the first command is successful, run the second command.

The /c is a cmd parameter for closing the window after the command is finished, and the /k is a cmd parameter for keeping the window open.

Credit to Adam Plocher for the staying in the current directory code.

Gradle Build Tools 2.2.0+ - Everything just works

This is the correct way to do it

In trying to avoid experimental and frankly fed up with the NDK and all its hackery I am happy that 2.2.x of the Gradle Build Tools came out and now it just works. The key is the externalNativeBuild and pointing ndkBuild path argument at an Android.mk or change ndkBuild to cmake and point the path argument at a CMakeLists.txt build script.

android {
    compileSdkVersion 19
    buildToolsVersion "25.0.2"

    defaultConfig {
        minSdkVersion 19
        targetSdkVersion 19

        ndk {
            abiFilters 'armeabi', 'armeabi-v7a', 'x86'
        }

        externalNativeBuild {
            cmake {
                cppFlags '-std=c++11'
                arguments '-DANDROID_TOOLCHAIN=clang',
                        '-DANDROID_PLATFORM=android-19',
                        '-DANDROID_STL=gnustl_static',
                        '-DANDROID_ARM_NEON=TRUE',
                        '-DANDROID_CPP_FEATURES=exceptions rtti'
            }
        }
    }

    externalNativeBuild {
        cmake {
             path 'src/main/jni/CMakeLists.txt'
        }
        //ndkBuild {
        //   path 'src/main/jni/Android.mk'
        //}
    }
}

For much more detail check Google's page on adding native code.

After this is setup correctly you can ./gradlew installDebug and off you go. You will also need to be aware that the NDK is moving to clang since gcc is now deprecated in the Android NDK.

I too, one way or another stumbled on the same dilemma, why the heck Excel VBA doesn't have a Date Picker. Thanks to Sid, who made an awesome job to create something for all of us.

Nonetheless, I came to a point where I need to create my own. And I am posting it here since a lot of people I'm sure lands on this post and benefit from it.

What I did was very simple as what Sid does except that I do not use a temporary worksheet. I thought the calculations are very simple and straight forward so there's no need to dump it somewhere else. Here's the final output of the calendar:

How to set it up:

• Create 42 Label controls and name it sequentially and arranged left to right, top to bottom (This labels contains greyed 25 up to greyed 5 above). Change the name of the Label controls to Label_01,Label_02 and so on. Set all 42 labels Tag property to dts.
• Create 7 more Label controls for the header (this will contain Su,Mo,Tu...)
• Create 2 more Label control, one for the horizontal line (height set to 1) and one for the Month and Year display. Name the Label used for displaying month and year Label_MthYr
• Insert 2 Image controls, one to contain the left icon to scroll previous months and one to scroll next month (I prefer simple left and right arrow head icon). Name it Image_Left and Image_Right

The layout should be more or less like this (I leave the creativity to anyone who'll use this).

Declaration:
We need one variable declared at the very top to hold the current month selected.

Option Explicit
Private curMonth As Date

Private Procedure and Functions:

Private Function FirstCalSun(ref_date As Date) As Date
    '/* returns the first Calendar sunday */
    FirstCalSun = DateSerial(Year(ref_date), _
                  Month(ref_date), 1) - (Weekday(ref_date) - 1)
End Function

Private Sub Build_Calendar(first_sunday As Date)
    '/* This builds the calendar and adds formatting to it */
    Dim lDate As MSForms.Label
    Dim i As Integer, a_date As Date

    For i = 1 To 42
        a_date = first_sunday + (i - 1)
        Set lDate = Me.Controls("Label_" & Format(i, "00"))
        lDate.Caption = Day(a_date)
        If Month(a_date) <> Month(curMonth) Then
            lDate.ForeColor = &H80000011
        Else
            If Weekday(a_date) = 1 Then
                lDate.ForeColor = &HC0&
            Else
                lDate.ForeColor = &H80000012
            End If
        End If
    Next
End Sub

Private Sub select_label(msForm_C As MSForms.Control)
    '/* Capture the selected date */
    Dim i As Integer, sel_date As Date
    i = Split(msForm_C.Name, "_")(1) - 1
    sel_date = FirstCalSun(curMonth) + i

    '/* Transfer the date where you want it to go */
    MsgBox sel_date

End Sub

Image Events:

Private Sub Image_Left_Click()

    If Month(curMonth) = 1 Then
        curMonth = DateSerial(Year(curMonth) - 1, 12, 1)
    Else
        curMonth = DateSerial(Year(curMonth), Month(curMonth) - 1, 1)
    End If

    With Me
        .Label_MthYr.Caption = Format(curMonth, "mmmm, yyyy")
        Build_Calendar FirstCalSun(curMonth)
    End With

End Sub

Private Sub Image_Right_Click()

    If Month(curMonth) = 12 Then
        curMonth = DateSerial(Year(curMonth) + 1, 1, 1)
    Else
        curMonth = DateSerial(Year(curMonth), Month(curMonth) + 1, 1)
    End If

    With Me
        .Label_MthYr.Caption = Format(curMonth, "mmmm, yyyy")
        Build_Calendar FirstCalSun(curMonth)
    End With

End Sub

I added this to make it look like the user is clicking the label and should be done on the Image_Right control too.

Private Sub Image_Left_MouseDown(ByVal Button As Integer, ByVal Shift As Integer, _
                                 ByVal X As Single, ByVal Y As Single)
    Me.Image_Left.BorderStyle = fmBorderStyleSingle
End Sub

Private Sub Image_Left_MouseUp(ByVal Button As Integer, ByVal Shift As Integer, _
                               ByVal X As Single, ByVal Y As Single)
    Me.Image_Left.BorderStyle = fmBorderStyleNone
End Sub

Label Events:
All of this should be done for all 42 labels (Label_01 to Lable_42)
Tip: Build the first 10 and just use find and replace for the remaining.

Private Sub Label_01_Click()
    select_label Me.Label_01
End Sub

This is for hovering over dates and clicking effect.

Private Sub Label_01_MouseDown(ByVal Button As Integer, ByVal Shift As Integer, _
                               ByVal X As Single, ByVal Y As Single)
    Me.Label_01.BorderStyle = fmBorderStyleSingle
End Sub

Private Sub Label_01_MouseMove(ByVal Button As Integer, ByVal Shift As Integer, _
                               ByVal X As Single, ByVal Y As Single)
    Me.Label_01.BackColor = &H8000000B
End Sub

Private Sub Label_01_MouseUp(ByVal Button As Integer, ByVal Shift As Integer, _
                             ByVal X As Single, ByVal Y As Single)
    Me.Label_01.BorderStyle = fmBorderStyleNone
End Sub

UserForm Events:

Private Sub UserForm_Initialize()
    '/* This is to initialize everything */
    With Me
        curMonth = DateSerial(Year(Date), Month(Date), 1)
        .Label_MthYr = Format(curMonth, "mmmm, yyyy")
        Build_Calendar FirstCalSun(curMonth)
    End With

End Sub

Again, just for the hovering over dates effect.

Private Sub UserForm_MouseMove(ByVal Button As Integer, ByVal Shift As Integer, _
                               ByVal X As Single, ByVal Y As Single)

    With Me
        Dim ctl As MSForms.Control, lb As MSForms.Label

        For Each ctl In .Controls
            If ctl.Tag = "dts" Then
                Set lb = ctl: lb.BackColor = &H80000005
            End If
        Next
    End With

End Sub

And that's it. This is raw and you can add your own twist to it.
I've been using this for awhile and I have no issues (performance and functionality wise).
No Error Handling yet but can be easily managed I guess.
Actually, without the effects, the code is too short.
You can manage where your dates go in the select_label procedure. HTH.

this usualy works on Checkboxes and Radio buttons... but, each name should be the same.

<input type="text" value="2" name="pages_title[]">
<input type="text" value="1" name="pages_title[]">

var x = $('input[name="pages_title[]"]').val();

that is "supposed" to get you all the fields in comma separated values. never tried it with text boxes, so cant guarantee it.

as @John commented: to iterate over them. $('input[name="pages_title[]"]').each(function() { var aValue = $(this).val(); });

EDIT: Not allways you need just to answer the OP questions, sometimes you need to teach them better methods. (sorry if that sounds Arrogant)

COMMENT: defining inputs as

<input type="text" value="1" name="pages_title[1]">
<input type="text" value="2" name="pages_title[2]">

is breaking the array, each input has a unique name, therefor, it is not an array anymore.

Just use this. It works only for android api >= 11 before that you'll have to use a ClipData.

ClipboardManager _clipboard = (ClipboardManager) _activity.getSystemService(Context.CLIPBOARD_SERVICE);
_clipboard.setText(YOUR TEXT);

Hope it helped you :)

[UPDATE 3/19/2015] Just like Ujjwal Singh said it the method setText is deprecated now, you should use, just as the docs recommande it, setPrimaryClip(clipData)

CTRL+SHIFT+ENTER, ARRAY FORMULA EXCEL 2016 MAC. So I arrive late into the game, but maybe someone else will. This almost drove me nuts. No matter what I searched for in Google I came up empty. Whatever I tried, no solution seemed to be in sight. Switched to Excel 2016 quite some time ago and today I needed to do some array formulas. Also sitting on a MacBook Pro 15 Touch Bar 2016. Not that it really matters, but still, since the solution was published on Youtube in 2013. The reason why, for me anyway, nothing worked, is in the Mac OS, the control key by default, for me anyway, is set to manage Mission control, which, at least for me, disabled the control button in Excel. In order to enable the key to actually control functions in Excel, you need to go to System preferences > Mission Control, and disable shortcuts for Mission control. So, let's see how long this solution will last. Probably be back to square one after the coffee break. Have a good one!

While only a few lines are required to plot multiple/overlapping histograms in ggplot2, the results are't always satisfactory. There needs to be proper use of borders and coloring to ensure the eye can differentiate between histograms.

The following functions balance border colors, opacities, and superimposed density plots to enable the viewer to differentiate among distributions.

Single histogram:

plot_histogram <- function(df, feature) {
    plt <- ggplot(df, aes(x=eval(parse(text=feature)))) +
    geom_histogram(aes(y = ..density..), alpha=0.7, fill="#33AADE", color="black") +
    geom_density(alpha=0.3, fill="red") +
    geom_vline(aes(xintercept=mean(eval(parse(text=feature)))), color="black", linetype="dashed", size=1) +
    labs(x=feature, y = "Density")
    print(plt)
}

Multiple histogram:

plot_multi_histogram <- function(df, feature, label_column) {
    plt <- ggplot(df, aes(x=eval(parse(text=feature)), fill=eval(parse(text=label_column)))) +
    geom_histogram(alpha=0.7, position="identity", aes(y = ..density..), color="black") +
    geom_density(alpha=0.7) +
    geom_vline(aes(xintercept=mean(eval(parse(text=feature)))), color="black", linetype="dashed", size=1) +
    labs(x=feature, y = "Density")
    plt + guides(fill=guide_legend(title=label_column))
}

Usage:

Simply pass your data frame into the above functions along with desired arguments:

plot_histogram(iris, 'Sepal.Width')

plot_multi_histogram(iris, 'Sepal.Width', 'Species')

The extra parameter in plot_multi_histogram is the name of the column containing the category labels.

We can see this more dramatically by creating a dataframe with many different distribution means:

a <-data.frame(n=rnorm(1000, mean = 1), category=rep('A', 1000))
b <-data.frame(n=rnorm(1000, mean = 2), category=rep('B', 1000))
c <-data.frame(n=rnorm(1000, mean = 3), category=rep('C', 1000))
d <-data.frame(n=rnorm(1000, mean = 4), category=rep('D', 1000))
e <-data.frame(n=rnorm(1000, mean = 5), category=rep('E', 1000))
f <-data.frame(n=rnorm(1000, mean = 6), category=rep('F', 1000))
many_distros <- do.call('rbind', list(a,b,c,d,e,f))

Passing data frame in as before (and widening chart using options):

options(repr.plot.width = 20, repr.plot.height = 8)
plot_multi_histogram(many_distros, 'n', 'category')

With new feature in docker option --config, you needn't set Proxy in Dockerfile any more. You can have same Dockerfile to be used in and out corporate environment.

--config string      Location of client config files (default "~/.docker")

or environment variable DOCKER_CONFIG

`DOCKER_CONFIG` The location of your client configuration files.

$ export DOCKER_CONFIG=~/.docker

https://docs.docker.com/engine/reference/commandline/cli/

https://docs.docker.com/network/proxy/

I recommend to set proxy with httpProxy, httpsProxy, ftpProxy and noProxy (The official document misses the variable ftpProxy which is useful sometimes)

{
 "proxies":
 {
   "default":
   {
     "httpProxy": "http://127.0.0.1:3001",
     "httpsProxy": "http://127.0.0.1:3001",
     "ftpProxy": "http://127.0.0.1:3001",
     "noProxy": "*.test.example.com,.example2.com"
   }
 }
}

Adjust proxy IP and port if needed and save to ~/.docker/config.json

After yo set properly with it, you can run docker build and docker run as normal.

$ docker build -t demo . 

$ docker run -ti --rm demo env|grep -ri proxy
(standard input):http_proxy=http://127.0.0.1:3001
(standard input):HTTPS_PROXY=http://127.0.0.1:3001
(standard input):https_proxy=http://127.0.0.1:3001
(standard input):NO_PROXY=*.test.example.com,.example2.com
(standard input):no_proxy=*.test.example.com,.example2.com
(standard input):FTP_PROXY=http://127.0.0.1:3001
(standard input):ftp_proxy=http://127.0.0.1:3001
(standard input):HTTP_PROXY=http://127.0.0.1:3001

Old answer (Decommissioned)

Below setting in Dockerfile works for me. I tested in CoreOS, Vagrant and boot2docker. Suppose the proxy port is 3128

In Centos:

ENV http_proxy=ip:3128 
ENV https_proxy=ip:3128

In Ubuntu:

ENV http_proxy 'http://ip:3128'
ENV https_proxy 'http://ip:3128'

Be careful of the format, some have http in it, some haven't, some with single quota. if the IP address is 192.168.0.193, then the setting will be:

In Centos:

ENV http_proxy=192.168.0.193:3128 
ENV https_proxy=192.168.0.193:3128

In Ubuntu:

ENV http_proxy 'http://192.168.0.193:3128'
ENV https_proxy 'http://192.168.0.193:3128'

If you need set proxy in coreos, for example to pull the image

cat /etc/systemd/system/docker.service.d/http-proxy.conf

[Service]
Environment="HTTP_PROXY=http://192.168.0.193:3128"

I know its long after this question was asked and answered - and I am sure that the accepted solution is right, but the purist in me would rather not add an extra element to the SVG when I can achieve the same or similar with straight CSS.

Whilst it is true that you cannot style the g container element in most ways - you can definitely add an outline to it and style that - even changing it on hover of the g - as shown in the snippet.

It not as good in one regard as the other way - you can put the outline box around the grouped elements - but not a background behind it. Sot its not perfect and won't solve the issue for everyone - but I would rather have the outline done with css than have to add extra elements to the code just to provide styling hooks.

And this method definitely allows you to show grouping of related objects in your SVG's.

Just a thought.

g {_x000D_
    outline: solid 3px blue;_x000D_
    outline-offset: 5px;_x000D_
  }_x000D_
_x000D_
g:hover {_x000D_
 outline-color: red_x000D_
}

<svg width="640" height="480" xmlns="http://www.w3.org/2000/svg">_x000D_
  <g>_x000D_
    <rect fill="blue" stroke-width="2" height="112" width="84" y="55" x="55" stroke-linecap="null" stroke-linejoin="null" stroke-dasharray="null" stroke="#000000"/>_x000D_
    <ellipse fill="#FF0000" stroke="#000000" stroke-width="5" stroke-dasharray="null" stroke-linejoin="null" stroke-linecap="null" cx="155" cy="65" id="svg_7" rx="64" ry="56"/>     _x000D_
  </g>_x000D_
</svg>

Perhaps you would accomplish this with something to the effect of

text = raw_input("please give 2 numbers to multiply separated with a comma:")
split_text = text.split(',')
a = int(split_text[0])
b = int(split_text[1])
# The last three lines could be written: a, b = map(int, text.split(','))
# but you may find the code I used a bit easier to understand for now.

if b > 0:
    num_times = b
else:
    num_times = -b

total = 0
# While loops with counters basically should not be used, so I replaced the loop 
# with a for loop. Using a while loop at all is rare.
for i in xrange(num_times):
    total += a 
    # We do this a times, giving us total == a * abs(b)

if b < 0:
    # If b is negative, adjust the total to reflect this.
    total = -total

print total

or maybe

a * b

This could also occur if you refer to a variable in the data.frame that doesn't exist. For example, recently I forgot to tell ddply to summarize by one of my variables that I used in geom_line to specify line color. Then, ggplot didn't know where to find the variable I hadn't created in the summary table, and I got this error.

Using "limit" and "top" will not work with all SQL servers (for example with Oracle). You can try a more complex query in pure sql:

select mt1.id, mt1."name", mt1.score, mt1."date" from mytable mt1
where mt1.id=2
and mt1."date"= (select min(mt2."date") from mytable mt2 where mt2.id=2)

You cannot initialize reference types by default other than null. You have to make them readonly. So this could work;

    readonly MyStruct[] MyArray = new MyStruct[]{
      new MyStruct{ label = "a", id = 1},
      new MyStruct{ label = "b", id = 5},
      new MyStruct{ label = "c", id = 1}
    };

An Another approach :) easier for flutter web

class SampleView extends StatelessWidget {
@override
Widget build(BuildContext context) {
 return Center(
  child: Container(
    width: 200,
    height: 200,
    color: Responsive().getResponsiveValue(
        forLargeScreen: Colors.red,
        forMediumScreen: Colors.green,
        forShortScreen: Colors.yellow,
        forMobLandScapeMode: Colors.blue,
        context: context),
    // You dodn't need to provide the values for every 
    //parameter(except shortScreen & context)
    // but default its provide the value as ShortScreen for Larger and 
    //mediumScreen
    ),
   );
 }
}



 // utility 
          class Responsive {
            // function reponsible for providing value according to screensize
            getResponsiveValue(
                {dynamic forShortScreen,
                dynamic forMediumScreen,
                dynamic forLargeScreen,
                dynamic forMobLandScapeMode,
                BuildContext context}) {

              if (isLargeScreen(context)) {

                return forLargeScreen ?? forShortScreen;
              } else if (isMediumScreen(context)) {

                return forMediumScreen ?? forShortScreen;
              } 
           else if (isSmallScreen(context) && isLandScapeMode(context)) {

                return forMobLandScapeMode ?? forShortScreen;
              } else {
                return forShortScreen;
              }
            }
          
            isLandScapeMode(BuildContext context) {
              if (MediaQuery.of(context).orientation == Orientation.landscape) {
                return true;
              } else {
                return false;
              }
            }
          
            static bool isLargeScreen(BuildContext context) {
              return getWidth(context) > 1200;
            }
          
            static bool isSmallScreen(BuildContext context) {
              return getWidth(context) < 800;
            }
          
            static bool isMediumScreen(BuildContext context) {
              return getWidth(context) > 800 && getWidth(context) < 1200;
            }
          
            static double getWidth(BuildContext context) {
              return MediaQuery.of(context).size.width;
            }
          }

You should consider using a button for this. Links generally should be use for linking. Buttons can be used for other functionality you wish to add. Neals solution works, but its a workaround.

If you use a <button> instead of a <a>, your original code should work as expected.

std::vector has a constructor that takes two iterators. You can use that:

std::string str = "hello";
std::vector<char> data(str.begin(), str.end());

If you already have a vector and want to add the characters at the end, you need a back inserter:

std::string str = "hello";
std::vector<char> data = /* ... */;
std::copy(str.begin(), str.end(), std::back_inserter(data));

Since you did not provide an attribute for the 'item' value, I am assuming a class is being used:

<div class='item1'>
  <span>This is my name</span>
</div>

alert($(".item span").text());

Make sure you wait for the DOM to load to use your code, in jQuery you use the ready() function for that:

<html>
 <head>
  <title>jQuery test</title>
  <!-- script that inserts jquery goes here -->
  <script type='text/javascript'>
    $(document).ready(function() { alert($(".item span").text()); });
  </script>
</head>
<body>
 <div class='item1'>
   <span>This is my name</span>
 </div>
</body>

If you want to load the file, as part of your app functionality, then the best approach would be to include and reference to that file.

Another approach is to ask for the file, and load it during runtime. This can be done with the FileAPI. There is also another StackOverflow answer about using it: How to open a local disk file with Javascript?

I will include a slightly modified version for using it in React:

class App extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      data: null
    };
    this.handleFileSelect = this.handleFileSelect.bind(this);
  }

  displayData(content) {
    this.setState({data: content});
  }

  handleFileSelect(evt) {
    let files = evt.target.files;
    if (!files.length) {
      alert('No file select');
      return;
    }
    let file = files[0];
    let that = this;
    let reader = new FileReader();
    reader.onload = function(e) {
      that.displayData(e.target.result);
    };
    reader.readAsText(file);
  }

  render() {
    const data = this.state.data;
    return (
      <div>
        <input type="file" onChange={this.handleFileSelect}/>
        { data && <p> {data} </p> }
      </div>
    );
  }
}

Also when I hit the post(Config.getURL("login"), values) the app seems to pause for a while (seems weird - thought the idea behind a service was that it runs on a different thread!)

No you have to create a thread yourself, a Local service runs in the UI thread by default.

with exit code 80131506

That's a nasty one, ExecutionEngineException. Starting with .NET 4.0, this exception immediately terminates the program. The generic cause is corruption of the state of the garbage collected heap. Which in turn is invariably caused by unmanaged code. The exact location in code at which this exception is raised isn't helpful, the corruption usually occurred well before the damage is detected.

Finding the exact cause for this is going to be difficult. Review any unmanaged code your service might be using. Suspect environmental problems if there is no obvious candidate, misbehaving malware scanners are notorious. If it repeats very poorly then suspect hardware problems like soft RAM errors.

I couldn't get IsNothing() to behave and I didn't want to create dummy rows in my dataset (e.g. for a given list of customers create a dummy order per month displayed) and noticed that null values were displaying as -247192.

Lo and behold using that worked to suppress it (at least until MSFT changes SSRS for the better from 08R2) so forgive me but:

=iif(Fields!Sales_Diff.Value = -247192,"",Fields!Sales_Diff.Value)

What about using a tabular inside \author{}, just like in IEEE macros:

\documentclass{article}
\begin{document}
\title{Hello, World}
\author{
\begin{tabular}[t]{c@{\extracolsep{8em}}c} 
I. M. Author  & M. Y. Coauthor \\
My Department & Coauthor Department \\ 
My Institute & Coauthor Institute \\
email, address & email, address
\end{tabular}
}
\maketitle    
\end{document}

This will produce two columns authors with any documentclass.

Results:

Conversion from symlinks could be useful. Link in a Git folder instead of a symlink by a script.

Swift 3 version

Swift 3 utilizes new DispatchQueue class to manage queues and threads. To run something on the background thread you would use:

let backgroundQueue = DispatchQueue(label: "com.app.queue", qos: .background)
backgroundQueue.async {
    print("Run on background thread")
}

Or if you want something in two lines of code:

DispatchQueue.global(qos: .background).async {
    print("Run on background thread")

    DispatchQueue.main.async {
        print("We finished that.")
        // only back on the main thread, may you access UI:
        label.text = "Done."
    }
}

You can also get some in-depth info about GDC in Swift 3 in this tutorial.

I recommend you to use an unordered list for your image gallery.

You should use my code unless you want the image to gain instantly 50% opacity after you hover out. You will have a smoother transition.

#photos li {
    opacity: .5;
    transition: opacity .5s ease-out;
    -moz-transition: opacity .5s ease-out;
    -webkit-transition: opacity .5s ease-out;
    -o-transition: opacity .5s ease-out;
}

#photos li:hover {
    opacity: 1;
}

Yes, it's possible:

public void myMethod(int... numbers) { /* your code */ }

If you are going to compare any assigned value of the string i.e. primitive string, both "==" and .equals will work, but for the new string object you should use only .equals, and here "==" will not work.

Example:

String a = "name";

String b = "name";

if(a == b) and (a.equals(b)) will return true.

But

String a = new String("a");

In this case if(a == b) will return false

So it's better to use the .equals operator...

JQuery can't append elements to <svg> (it does seem to add them in the DOM explorer, but not on the screen).

One workaround is to append an <svg> with all of the elements that you need to the page, and then modify the attributes of the elements using .attr().

$('body')
  .append($('<svg><circle id="c" cx="10" cy="10" r="10" fill="green" /></svg>'))
  .mousemove( function (e) {
      $("#c").attr({
          cx: e.pageX,
          cy: e.pageY
      });
  });

The actual problem is not IE8, but the hacks that you use for earlier versions of IE.

IE8 is pretty close to be standards compliant, so you shouldn't need any hacks at all for it, perhaps only some tweaks. The problem is if you are using some hacks for IE6 and IE7; you will have to make sure that they only apply to those versions and not IE8.

I made the web site of our company compatible with IE8 a while ago. The only thing that I actually changed was adding the meta tag that tells IE that the pages are IE8 compliant...

You cannot iterate over them directly, but you can find all the keys and then just sort them.

var a = new Array();
a['b'] = 1;
a['z'] = 1;
a['a'] = 1;    

function keys(obj)
{
    var keys = [];

    for(var key in obj)
    {
        if(obj.hasOwnProperty(key))
        {
            keys.push(key);
        }
    }

    return keys;
}

keys(a).sort(); // ["a", "b", "z"]

However there is no need to make the variable 'a' an array. You are really just using it as an object and should create it like this:

var a = {};
a["key"] = "value";

I think your particular problem isn't how to use Glyphicons but understanding how Bootstrap files work together.

Bootstrap requires a specific file structure to work. I see from your code you have this:

<link href="bootstrap.css" rel="stylesheet" media="screen">

Your Bootstrap.css is being loaded from the same location as your page, this would create a problem if you didn't adjust your file structure.

But first, let me recommend you setup your folder structure like so:

/css      <-- Bootstrap.css here
/fonts    <-- Bootstrap fonts here
/img
/js       <-- Bootstrap JavaScript here
index.html

If you notice, this is also how Bootstrap structures its files in its download ZIP.

You then include your Bootstrap file like so:

<link href="css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="./css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="/css/bootstrap.css" rel="stylesheet" media="screen">

Depending on your server structure or what you're going for.

The first and second are relative to your file's current directory. The second one is just more explicit by saying "here" (./) first then css folder (/css).

The third is good if you're running a web server, and you can just use relative to root notation as the leading "/" will be always start at the root folder.

So, why do this?

Bootstrap.css has this specific line for Glyphfonts:

@font-face {
    font-family: 'Glyphicons Halflings';
    src: url('../fonts/glyphicons-halflings-regular.eot');
    src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');
}

What you can see is that that Glyphfonts are loaded by going up one directory ../ and then looking for a folder called /fonts and THEN loading the font file.

The URL address is relative to the location of the CSS file. So, if your CSS file is at the same location like this:

/fonts
Bootstrap.css
index.html

The CSS file is going one level deeper than looking for a /fonts folder.

So, let's say the actual location of these files are:

C:\www\fonts
C:\www\Boostrap.css
C:\www\index.html

The CSS file would technically be looking for a folder at:

C:\fonts

but your folder is actually in:

C:\www\fonts

So see if that helps. You don't have to do anything 'special' to load Bootstrap Glyphicons, except make sure your folder structure is set up appropriately.

When you get that fixed, your HTML should simply be:

<span class="glyphicon glyphicon-comment"></span>

Note, you need both classes. The first class glyphicon sets up the basic styles while glyphicon-comment sets the specific image.

also try

## Notice the lack of quotes
iris %>% select (-c(Sepal.Length, Sepal.Width))

The first answer is good and gives some structural answers, but another approach is to think about what you're doing. Modules are about providing methods that you can use across multiple classes - think about them as "libraries" (as you would see in a Rails app). Classes are about objects; modules are about functions.

For example, authentication and authorization systems are good examples of modules. Authentication systems work across multiple app-level classes (users are authenticated, sessions manage authentication, lots of other classes will act differently based on the auth state), so authentication systems act as shared APIs.

You might also use a module when you have shared methods across multiple apps (again, the library model is good here).

I've managed to find a CSS workaround to preventing bouncing of the viewport. The key was to wrap the content in 3 divs with -webkit-touch-overflow:scroll applied to them. The final div should have a min-height of 101%. In addition, you should explicitly set fixed widths/heights on the body tag representing the size of your device. I've added a red background on the body to demonstrate that it is the content that is now bouncing and not the mobile safari viewport.

Source code below and here is a plunker (this has been tested on iOS7 GM too). http://embed.plnkr.co/NCOFoY/preview

If you intend to run this as a full-screen app on iPhone 5, modify the height to 1136px (when apple-mobile-web-app-status-bar-style is set to 'black-translucent' or 1096px when set to 'black'). 920x is the height of the viewport once the chrome of mobile safari has been taken into account).

Very nice example using paste and substitute to typeset both symbols (mathplot) and variables at http://vis.supstat.com/2013/04/mathematical-annotation-in-r/

Here is a ggplot adaptation

x_mean <- 1.5
x_sd <- 1.2
N <- 500

n <- ggplot(data.frame(x <- rnorm(N, x_mean, x_sd)),aes(x=x)) +
    geom_bar() + stat_bin() +
    labs(title=substitute(paste(
             "Histogram of random data with ",
             mu,"=",m,", ",
             sigma^2,"=",s2,", ",
             "draws = ", numdraws,", ",
             bar(x),"=",xbar,", ",
             s^2,"=",sde),
             list(m=x_mean,xbar=mean(x),s2=x_sd^2,sde=var(x),numdraws=N)))

The HTTP Content-Type for .ogg should be application/ogg (video/ogg for .ogv) and for .mp4 it should be video/mp4. You can check using the Web Sniffer.

Try this:

A very simple way to count the columns of the first line in pure bash (no awk, perl, or other languages):

read -r line < $input_file
ncols=`echo $line | wc -w`

This will work if your data are formatted appropriately.

I've enhanced the mustache.js example adding the escapeHTML() method to the string object.

var __entityMap = {
    "&": "&",
    "<": "&lt;",
    ">": "&gt;",
    '"': '&quot;',
    "'": '&#39;',
    "/": '&#x2F;'
};

String.prototype.escapeHTML = function() {
    return String(this).replace(/[&<>"'\/]/g, function (s) {
        return __entityMap[s];
    });
}

That way it is quite easy to use "Some <text>, more Text&Text".escapeHTML()

I found the answer :)

Use JsonPath or XmlPath (in case you have XML) to get data from the response body.

In my case:

JsonPath jsonPath = new JsonPath(responseBody);
int user_id = jsonPath.getInt("user_id");

Open Terminal/command prompt in the respective project directory and type following command.

npm install --save bootstrap

Then open .angular-cli.json file, Look for

"styles": [ "styles.css" ],

change that to

 "styles": [
    "../node_modules/bootstrap/dist/css/bootstrap.min.css",
    "styles.css"
  ],

All done.

I tend to agree that refactoring into a function is usually the best approach for this sort of situation, but for when you really need to break out of nested loops, here's an interesting variant of the exception-raising approach that @S.Lott described. It uses Python's with statement to make the exception raising look a bit nicer. Define a new context manager (you only have to do this once) with:

from contextlib import contextmanager
@contextmanager
def nested_break():
    class NestedBreakException(Exception):
        pass
    try:
        yield NestedBreakException
    except NestedBreakException:
        pass

Now you can use this context manager as follows:

with nested_break() as mylabel:
    while True:
        print "current state"
        while True:
            ok = raw_input("Is this ok? (y/n)")
            if ok == "y" or ok == "Y": raise mylabel
            if ok == "n" or ok == "N": break
        print "more processing"

Advantages: (1) it's slightly cleaner (no explicit try-except block), and (2) you get a custom-built Exception subclass for each use of nested_break; no need to declare your own Exception subclass each time.

main.cpp doesn't have to know what is in class.cpp. It just has to know the declarations of the functions/classes that it goes to use, and these declarations are in class.h.

The linker links between the places where the functions/classes declared in class.h are used and their implementations in class.cpp

Don't forget to include <typeinfo>

I believe what you are referring to is runtime type identification. You can achieve the above by doing .

#include <iostream>
#include <typeinfo>

using namespace std;

int main() {
  int i;
  cout << typeid(i).name();
  return 0;
}

Just adding an answer because I came to this question to see the best way to include the version from package.json in my web application.

I know this question is targetted for Node.js however, if you are using Webpack to bundle your app just a reminder the recommended way is to use the DefinePlugin to declare a global version in the config and reference that. So you could do in your webpack.config.json

const pkg = require('../../package.json');

...

plugins : [
    new webpack.DefinePlugin({
      AppVersion: JSON.stringify(pkg.version),
...

And then AppVersion is now a global that is available for you to use. Also make sure in your .eslintrc you ignore this via the globals prop

It's because you're missing position:relative; on #contentframe

<div id="contentframe" style="position:relative; top: 160px; left: 0px;">

position:absolute; positions itself against the closest ancestor that has a position that is not static. Since the default is static that is what was causing your issue.

I don't see any answers yet that mention performance. Passing Func<>s into Where() or Count() is bad. Real bad. If you use a Func<> then it calls the IEnumerable LINQ stuff instead of IQueryable, which means that whole tables get pulled in and then filtered. Expression<Func<>> is significantly faster, especially if you are querying a database that lives another server.

            UIAlertAction in
            NSLog("Cancel Pressed")
        }

        // Add the actions
        alertController.addAction(okAction)
        alertController.addAction(cancelAction)

        // Present the controller
        self.present(alertController, animated: true, completion: nil)

    if (document.getElementById('remember').checked) {
        alert("checked");
    }
    else {
        alert("You didn't check it! Let me check it for you.");
    }

Short answer - Deleted .m2 folder in {user.home}. E.g. in windows 10 user home is C:\Users\user1. Re-build your project using mvn clean package. Only those dependencies would remain, which are required by the projects.

Long Answer - .m2 folder is just like a normal folder and the content of the folder is built from different projects. I think there is no way to figure out automatically that which library is "old". In fact old is a vague word. There could be so many reasons when a previous version of a library is used in a project, hence determining which one is unused is not possible.

All you could do, is to delete the .m2 folder and re-build all of your projects and then the folder would automatically build with all the required library.

If you are concern about only a particular version of a library to be used in all the projects; it is important that the project's pom should also update to latest version. i.e. if different POMs refer different versions of the library, all will get downloaded in .m2.

This does not answer the question directly, but I have on different occasions landed on this Stack Overflow question in order to solve something I would use $watch for in angularJs. I ended up using another approach than described in the current answers, and want to share it in case someone finds it useful.

The technique I use to achieve something similar $watch is to use a BehaviorSubject (more on the topic here) in an Angular service, and let my components subscribe to it in order to get (watch) the changes. This is similar to a $watch in angularJs, but require some more setup and understanding.

In my component:

export class HelloComponent {
  name: string;
  // inject our service, which holds the object we want to watch.
  constructor(private helloService: HelloService){
    // Here I am "watching" for changes by subscribing
    this.helloService.getGreeting().subscribe( greeting => {
      this.name = greeting.value;
    });
  }
}

In my service

export class HelloService {
  private helloSubject = new BehaviorSubject<{value: string}>({value: 'hello'});
  constructor(){}
  // similar to using $watch, in order to get updates of our object 
  getGreeting(): Observable<{value:string}> {
    return this.helloSubject;
  }
  // Each time this method is called, each subscriber will receive the updated greeting.
  setGreeting(greeting: string) {
    this.helloSubject.next({value: greeting});
  }
}

Building on pkozlowski.opensource's answer, I've added a way to have dynamic input names that also work with ngMessages. Note the ng-init part on the ng-form element and the use of furryName. furryName becomes the variable name that contains the variable value for the input's name attribute.

<ion-item ng-repeat="animal in creatures track by $index">
<ng-form name="animalsForm" ng-init="furryName = 'furry' + $index">
        <!-- animal is furry toggle buttons -->
        <input id="furryRadio{{$index}}"
               type="radio"
               name="{{furryName}}"
               ng-model="animal.isFurry"
               ng-value="radioBoolValues.boolTrue"
               required
                >
        <label for="furryRadio{{$index}}">Furry</label>

        <input id="hairlessRadio{{$index}}"
               name="{{furryName}}"
               type="radio"
               ng-model="animal.isFurry"
               ng-value="radioBoolValues.boolFalse"
               required
               >
        <label for="hairlessRadio{{$index}}">Hairless</label>

        <div ng-messages="animalsForm[furryName].$error"
             class="form-errors"
             ng-show="animalsForm[furryName].$invalid && sectionForm.$submitted">
            <div ng-messages-include="client/views/partials/form-errors.ng.html"></div>
        </div>
</ng-form>
</ion-item>

Not a direct answer, but a slight variation to use the "functor" template pattern to hide away the specifics of the lambda type and keeps the code nice and simple.

I was not sure how you wanted to use the decide class so I had to extend the class with a function that uses it. See full example here: https://godbolt.org/z/jtByqE

The basic form of your class might look like this:

template <typename Functor>
class Decide
{
public:
    Decide(Functor dec) : _dec{dec} {}
private:
    Functor _dec;
};

Where you pass the type of the function in as part of the class type used like:

auto decide_fc = [](int x){ return x > 3; };
Decide<decltype(decide_fc)> greaterThanThree{decide_fc};

Again, I was not sure why you are capturing x it made more sense (to me) to have a parameter that you pass in to the lambda) so you can use like:

int result = _dec(5); // or whatever value

See the link for a complete example

# list packages that can be updated
conda search --outdated

# update all packages prompted(by asking the user yes/no)
conda update --all

# update all packages unprompted
conda update --all -y

Two good examples are regarding how you manage templates and use progressive enhancements with it. You just need a few lightweight pieces of JavaScript code to make it work perfectly.

I strongly recommend that you watch and read these articles:

• Video glass node
• Node.js YUI DOM manipulation

Pick up any language and try to remember how you would manage your HTML file templates and what you had to do to update a single CSS class name in your DOM structure (for instance, a user clicked on a menu item and you want that marked as "selected" and update the content of the page).

With Node.js it is as simple as doing it in client-side JavaScript code. Get your DOM node and apply your CSS class to that. Get your DOM node and innerHTML your content (you will need some additional JavaScript code to do this. Read the article to know more).

Another good example, is that you can make your web page compatible both with JavaScript turned on or off with the same piece of code. Imagine you have a date selection made in JavaScript that would allow your users to pick up any date using a calendar. You can write (or use) the same piece of JavaScript code to make it work with your JavaScript turned ON or OFF.

What's probably happening is that React thinks that only one MyInput (unemployment-duration) is added between the renders. As such, the job-title never gets replaced with the unemployment-reason, which is also why the predefined values are swapped.

When React does the diff, it will determine which components are new and which are old based on their key property. If no such key is provided in the code, it will generate its own.

The reason why the last code snippet you provide works is because React essentially needs to change the hierarchy of all elements under the parent div and I believe that would trigger a re-render of all children (which is why it works). Had you added the span to the bottom instead of the top, the hierarchy of the preceding elements wouldn't change, and those element's wouldn't re-render (and the problem would persist).

Here's what the official React documentation says:

The situation gets more complicated when the children are shuffled around (as in search results) or if new components are added onto the front of the list (as in streams). In these cases where the identity and state of each child must be maintained across render passes, you can uniquely identify each child by assigning it a key.

When React reconciles the keyed children, it will ensure that any child with key will be reordered (instead of clobbered) or destroyed (instead of reused).

You should be able to fix this by providing a unique key element yourself to either the parent div or to all MyInput elements.

For example:

render(){
    if (this.state.employed) {
        return (
            <div key="employed">
                <MyInput ref="job-title" name="job-title" />
            </div>
        );
    } else {
        return (
            <div key="notEmployed">
                <MyInput ref="unemployment-reason" name="unemployment-reason" />
                <MyInput ref="unemployment-duration" name="unemployment-duration" />
            </div>
        );
    }
}

OR

render(){
    if (this.state.employed) {
        return (
            <div>
                <MyInput key="title" ref="job-title" name="job-title" />
            </div>
        );
    } else {
        return (
            <div>
                <MyInput key="reason" ref="unemployment-reason" name="unemployment-reason" />
                <MyInput key="duration" ref="unemployment-duration" name="unemployment-duration" />
            </div>
        );
    }
}

Now, when React does the diff, it will see that the divs are different and will re-render it including all of its' children (1st example). In the 2nd example, the diff will be a success on job-title and unemployment-reason since they now have different keys.

You can of course use any keys you want, as long as they are unique.

Update August 2017

For a better insight into how keys work in React, I strongly recommend reading my answer to Understanding unique keys in React.js.

Update November 2017

This update should've been posted a while ago, but using string literals in ref is now deprecated. For example ref="job-title" should now instead be ref={(el) => this.jobTitleRef = el} (for example). See my answer to Deprecation warning using this.refs for more info.

Here is my layout:

    <HorizontalScrollView
        android:id="@+id/horizontalScrollView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingTop="@dimen/padding" >

       <LinearLayout
        android:id="@+id/shapeLayout"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp" >
        </LinearLayout>
    </HorizontalScrollView>

And I populate it in the code with dynamic check-boxes.

@heridev and I created a small function in jQuery.

You can try next:

HTML

<input type="text" name="one" class="two-digits"><br>
<input type="text" name="two" class="two-digits">?

jQuery

// apply the two-digits behaviour to elements with 'two-digits' as their class
$( function() {
    $('.two-digits').keyup(function(){
        if($(this).val().indexOf('.')!=-1){         
            if($(this).val().split(".")[1].length > 2){                
                if( isNaN( parseFloat( this.value ) ) ) return;
                this.value = parseFloat(this.value).toFixed(2);
            }  
         }            
         return this; //for chaining
    });
});

Please try and check whether all the libs are in place. I had the same issue. But I solved it by moving the lib folder and adding all the jars again in the build path.

What you've got (according to the debug image) is an object array containing a string array. So you need something like:

Object[] objects = (Object[]) values;
String[] strings = (String[]) objects[0];

You haven't shown the type of values - if this is already Object[] then you could just use (String[])values[0].

Of course even with the cast to Object[] you could still do it in one statement, but it's ugly:

String[] strings = (String[]) ((Object[])values)[0];

Use the constants defined in the math package:

const (
    MaxInt8   = 1<<7 - 1
    MinInt8   = -1 << 7
    MaxInt16  = 1<<15 - 1
    MinInt16  = -1 << 15
    MaxInt32  = 1<<31 - 1
    MinInt32  = -1 << 31
    MaxInt64  = 1<<63 - 1
    MinInt64  = -1 << 63
    MaxUint8  = 1<<8 - 1
    MaxUint16 = 1<<16 - 1
    MaxUint32 = 1<<32 - 1
    MaxUint64 = 1<<64 - 1
)

Well, it depends on what language you are using, but in general they are 2 separate configurations, each with its own settings. By default, Debug includes debug information in the compiled files (allowing easy debugging) while Release usually has optimizations enabled.

As far as conditional compilation goes, they each define different symbols that can be checked in your program, but they are language-specific macros.
