SELECT t1.cname, t1.wmname, t2.max
FROM makerar t1 JOIN (
    SELECT cname, MAX(avg) max
    FROM makerar
    GROUP BY cname ) t2
ON t1.cname = t2.cname AND t1.avg = t2.max;

Using rank() window function:

SELECT cname, wmname, avg
FROM (
    SELECT cname, wmname, avg, rank() 
    OVER (PARTITION BY cname ORDER BY avg DESC)
    FROM makerar) t
WHERE rank = 1;

Note

Either one will preserve multiple max values per group. If you want only single record per group even if there is more than one record with avg equal to max you should check @ypercube's answer.

I found that the useful getResources().getColor(R.color.color_name) is deprecated.

It is not deprecated in API Level 21, according to the documentation.

It is deprecated in the M Developer Preview. However, the replacement method (a two-parameter getColor() that takes the color resource ID and a Resources.Theme object) is only available in the M Developer Preview.

Hence, right now, continue using the single-parameter getColor() method. Later this year, consider using the two-parameter getColor() method on Android M devices, falling back to the deprecated single-parameter getColor() method on older devices.

The TypeInitializationException that is thrown as a wrapper around the exception thrown by the class initializer. This class cannot be inherited.

TypeInitializationException is also called static constructors.

you need the set key and value in foreach loop for that:

foreach($item AS $key -> $value) {
echo $value;
}

this should do the trick :)

You can delete the node from the master by issuing:

kubectl delete node hostname.company.net

The NOTReady status probably means that the master can't access the kubelet service. Check if everything is OK on the client.

Or

-like '*'+$nameregex+'*'

if you would like to use wildcards.

The previous answers using the ISNULL function are correct only for MS Sql Server. The COALESCE function will also work in SQL Server. But will also work in standard SQL database systems. In the given example:

SELECT sum(COALESCE(TotalHoursM,0))
          + COALESCE(TotalHoursT,0)
          + COALESCE(TotalHoursW,0)
          + COALESCE(TotalHoursTH,0)
          + COALESCE(TotalHoursF,0) AS TOTAL FROM LeaveRequest

This is identical to the ISNULL solution with the only difference being the name of the function. Both work in SQL Server but, COALESCE is ANSI standard and ISNULL is not. Also, COALESCE is more flexible. ISNULL will only work with two parameters. If the first parameter is NULL then the value of the second parameter is returned, else the value of the first is returned. COALESCE will take 2 to 'n' (I don't know the limit of 'n') parameters and return the value of the first parameter that is not NULL. When there are only two parameters the effect is the same as ISNULL.

I find this to be the superior solution, at least when dealing with web applications. The idea is this: convert the HTML page to a PDF document and send that to a printer via gsprint.

Even though gsprint is no longer in development, it works really, really well. You can choose the printer and the page orientation and size among several other options.

I convert the web page to PDF using Puppeteer, Chrome's headless browser. But you need to pass in the session cookie to maintain credentials.

I would prefer to make a function that doesn't work with strings:

'---------------------------------------------------------------------------------------
' Procedure : RemoveTimeFromDate
' Author    : berend.nieuwhof
' Date      : 15-8-2013
' Purpose   : removes the time part of a String and returns the date as a date
'---------------------------------------------------------------------------------------
'
Public Function RemoveTimeFromDate(DateTime As Date) As Date


    Dim dblNumber As Double

    RemoveTimeFromDate = CDate(Floor(CDbl(DateTime)))

End Function

Private Function Floor(ByVal x As Double, Optional ByVal Factor As Double = 1) As Double
    Floor = Int(x / Factor) * Factor
End Function

function getCount(){
    return $this->db->get('table_name')->num_rows();
}

I want to create a 2D array that each cell is an ArrayList!

If you want to create a 2D array of ArrayList.Then you can do this :

ArrayList[][] table = new ArrayList[10][10];
table[0][0] = new ArrayList(); // add another ArrayList object to [0,0]
table[0][0].add(); // add object to that ArrayList

See here if you want to grant a Facebook App permanent access to a page (even when you / the app owner are logged out):

http://developers.facebook.com/docs/opengraph/using-app-tokens/

"An App Access Token does not expire unless you refresh the application secret through your app settings."

You can redirect the output of a cmd prompt to a file using > or >> to append to a file.

i.e.

echo Hello World >C:\output.txt
echo Hello again! >>C:\output.txt

or

mybatchfile.bat >C:\output.txt

Note that using > will automatically overwrite the file if it already exists.

You also have the option of redirecting stdin, stdout and stderr.

See here for a complete list of options.

hash.each do |key, array|
  puts "#{key}-----"
  puts array
end

Regarding order I should add, that in 1.8 the items will be iterated in random order (well, actually in an order defined by Fixnum's hashing function), while in 1.9 it will be iterated in the order of the literal.

Lot of the information above led me to further research and ultimately my answer so I wanted to contribute what I wound up doing in hopes it helps someone else:

• I also wanted to pass a varied number of variables to a batch file so that they could be processed within the file.

• I was ok with passing them to the batch file using quotes

• I would want them processed similar to the below - but using a loop instead of writing out manually:

So I wanted to execute this:

prog_ZipDeleteFiles.bat "_appPath=C:\Services\Logs\PCAP" "_appFile=PCAP*.?"

And via the magic of for loops do this within the batch file:

set "_appPath=C:\Services\Logs\PCAP"
set "_appFile=PCAP*.?"

Problem I was having is that all my attempts to use a for loop weren't working. The below example:

for /f "tokens* delims= " in %%A (%*) DO (
   set %%A
)

would just do:

set "_appPath=C:\Services\Logs\PCAP"

and not:

set "_appPath=C:\Services\Logs\PCAP"
set "_appFile=PCAP*.?"

even after setting

SETLOCAL EnableDelayedExpansion

Reason was that the for loop read the whole line and assigned my second parameter to %%B during the first iteration of the loop. Because %* represents all arguments, there is only a single line to process - ergo only one pass of the for loop happens. This is by design it turns out, and my logic was wrong.

So I stopped trying to use a for loop and simplified what I was trying to do by using if, shift, and a goto statement. Agreed its a bit of a hack but it's more suited to my needs. I can loop through all of the arguments and then use an if statement to drop out of the loop once I process them all.

The winning statement for what I was trying to accomplish:

echo on
:processArguments
:: Process all arguments in the order received
if defined %1 then (
    set %1
    shift
    goto:processArguments
) ELSE (
    echo off 
)

UPDATE - I had to modify to the below instead, I was exposing all of the environment variables when trying to reference %1 and using shift in this manner:

echo on
shift
:processArguments
:: Process all arguments in the order received
if defined %0 then (
    set %0
    shift
    goto:processArguments
) ELSE (
    echo off 
)

A sort of block comment uses an if statement:

if(FALSE) {
  all your code
}

It works, but I almost always use the block comment options of my editors (RStudio, Kate, Kwrite).

When you called notify on the notification manager you gave it an id - that is the unique id you can use to access it later (this is from the notification manager:

notify(int id, Notification notification)

To cancel, you would call:

cancel(int id)

with the same id. So, basically, you need to keep track of the id or possibly put the id into a Bundle you add to the Intent inside the PendingIntent?

In your stylesheet add:

@media print
{    
    .no-print, .no-print *
    {
        display: none !important;
    }
}

Then add class='no-print' (or add the no-print class to an existing class statement) in your HTML that you don't want to appear in the printed version, such as your button.

This question was already asked on https://tex.stackexchange.com/questions/10684/vertical-space-in-lists. The highest voted answer also mentioned the enumitem package (here answered by Stefan), but I also like this one, which involves creating your own itemizing environment instead of loading a new package:

\newenvironment{myitemize}
{ \begin{itemize}
    \setlength{\itemsep}{0pt}
    \setlength{\parskip}{0pt}
    \setlength{\parsep}{0pt}     }
{ \end{itemize}                  } 

Which should be used like this:

\begin{myitemize} 
  \item one 
  \item two 
  \item three 
\end{myitemize}

RFC 3066 gives the details of the allowed values (emphasis and links added):

All 2-letter subtags are interpreted as ISO 3166 alpha-2 country codes from [ISO 3166], or subsequently assigned by the ISO 3166 maintenance agency or governing standardization bodies, denoting the area to which this language variant relates.

I interpret that as meaning any valid (according to ISO 3166) 2-letter code is valid as a subtag. The RFC goes on to state:

Tags with second subtags of 3 to 8 letters may be registered with IANA, according to the rules in chapter 5 of this document.

By the way, that looks like a typo, since chapter 3 seems to relate to the the registration process, not chapter 5.

A quick search for the IANA registry reveals a very long list, of all the available language subtags. Here's one example from the list (which would be used as en-scouse):

Type: variant

Subtag: scouse

Description: Scouse

Added: 2006-09-18

Prefix: en

Comments: English Liverpudlian dialect known as 'Scouse'

There are all sorts of subtags available; a quick scroll has already revealed fr-1694acad (17th century French).

The usefulness of some of these (I would say the vast majority of these) tags, when it comes to documents designed for display in the browser, is limited. The W3C Internationalization specification simply states:

Browsers and other applications can use information about the language of content to deliver to users the most appropriate information, or to present information to users in the most appropriate way. The more content is tagged and tagged correctly, the more useful and pervasive such applications will become.

I'm struggling to find detailed information on how browsers behave when encountering different language tags, but they are most likely going to offer some benefit to those users who use a screen reader, which can use the tag to determine the language/dialect/accent in which to present the content.

I don't think your question is very clear, this code assumes that if you're going to include the -domain parameter, it's always 'named' (i.e. dostuff computername arg2 -domain domain); this also makes the computername parameter mandatory.

Function DoStuff(){
    param(
        [Parameter(Mandatory=$true)][string]$computername,
        [Parameter(Mandatory=$false)][string]$arg2,
        [Parameter(Mandatory=$false)][string]$domain
    )
    if(!($domain)){
        $domain = 'domain1'
    }
    write-host $domain
    if($arg2){
        write-host "arg2 present... executing script block"
    }
    else{
        write-host "arg2 missing... exiting or whatever"
    }
}

The setTimeout/setInterval solutions presented here will only work in specific circumstances.

The problem shows up especially in older Internet Explorer versions up to 8.

The variables affecting the success of these setTimeout/setInterval solutions are:

1) dynamic or static HTML
2) cached or non cached requests
3) size of the complete HTML document
4) chunked or non chunked transfer encoding

the original (native Javascript) code solving this specific issue is here:

https://github.com/dperini/ContentLoaded
http://javascript.nwbox.com/ContentLoaded (test)

this is the code from which the jQuery team have built their implementation.

I totally agree with both the question and Martin's answer :). Even in Java, reading javadoc with generics is much harder than it should be due to the extra noise. This is compounded in Scala where implicit parameters are used as in the questions's example code (while the implicits do very useful collection-morphing stuff).

I don't think its a problem with the language per se - I think its more a tooling issue. And while I agree with what Jörg W Mittag says, I think looking at scaladoc (or the documentation of a type in your IDE) - it should require as little brain power as possible to grok what a method is, what it takes and returns. There shouldn't be a need to hack up a bit of algebra on a bit of paper to get it :)

For sure IDEs need a nice way to show all the methods for any variable/expression/type (which as with Martin's example can have all the generics inlined so its nice and easy to grok). I like Martin's idea of hiding the implicits by default too.

To take the example in scaladoc...

def map[B, That](f: A => B)(implicit bf: CanBuildFrom[Repr, B, That]): That

When looking at this in scaladoc I'd like the generic block [B, That] to be hidden by default as well as the implicit parameter (maybe they show if you hover a little icon with the mouse) - as its extra stuff to grok reading it which usually isn't that relevant. e.g. imagine if this looked like...

def map(f: A => B): That

nice and clear and obvious what it does. You might wonder what 'That' is, if you mouse over or click it it could expand the [B, That] text highlighting the 'That' for example.

Maybe a little icon could be used for the [] declaration and (implicit...) block so its clear there are little bits of the statement collapsed? Its hard to use a token for it, but I'll use a . for now...

def map.(f: A => B).: That

So by default the 'noise' of the type system is hidden from the main 80% of what folks need to look at - the method name, its parameter types and its return type in nice simple concise way - with little expandable links to the detail if you really care that much.

Mostly folks are reading scaladoc to find out what methods they can call on a type and what parameters they can pass. We're kinda overloading users with way too much detail right how IMHO.

Here's another example...

def orElse[A1 <: A, B1 >: B](that: PartialFunction[A1, B1]): PartialFunction[A1, B1]

Now if we hid the generics declaration its easier to read

def orElse(that: PartialFunction[A1, B1]): PartialFunction[A1, B1]

Then if folks hover over, say, A1 we could show the declaration of A1 being A1 <: A. Covariant and contravariant types in generics add lots of noise too which can be rendered in a much easier to grok way to users I think.

If you've only got one DataView, you can sort using that instead:

table.DefaultView.Sort = "columnName asc";

Haven't tried it, but I guess you can do this with any number of DataViews, as long as you reference the right one.

In addition to given answer, it's worth noting that compiler is not required to initialize constexpr variable at compile time, knowing that the difference between constexpr and static constexpr is that to use static constexpr you ensure the variable is initialized only once.

Following code demonstrates how constexpr variable is initialized multiple times (with same value though), while static constexpr is surely initialized only once.

In addition the code compares the advantage of constexpr against const in combination with static.

#include <iostream>
#include <string>
#include <cassert>
#include <sstream>

const short const_short = 0;
constexpr short constexpr_short = 0;

// print only last 3 address value numbers
const short addr_offset = 3;

// This function will print name, value and address for given parameter
void print_properties(std::string ref_name, const short* param, short offset)
{
    // determine initial size of strings
    std::string title = "value \\ address of ";
    const size_t ref_size = ref_name.size();
    const size_t title_size = title.size();
    assert(title_size > ref_size);

    // create title (resize)
    title.append(ref_name);
    title.append(" is ");
    title.append(title_size - ref_size, ' ');

    // extract last 'offset' values from address
    std::stringstream addr;
    addr << param;
    const std::string addr_str = addr.str();
    const size_t addr_size = addr_str.size();
    assert(addr_size - offset > 0);

    // print title / ref value / address at offset
    std::cout << title << *param << " " << addr_str.substr(addr_size - offset) << std::endl;
}

// here we test initialization of const variable (runtime)
void const_value(const short counter)
{
    static short temp = const_short;
    const short const_var = ++temp;
    print_properties("const", &const_var, addr_offset);

    if (counter)
        const_value(counter - 1);
}

// here we test initialization of static variable (runtime)
void static_value(const short counter)
{
    static short temp = const_short;
    static short static_var = ++temp;
    print_properties("static", &static_var, addr_offset);

    if (counter)
        static_value(counter - 1);
}

// here we test initialization of static const variable (runtime)
void static_const_value(const short counter)
{
    static short temp = const_short;
    static const short static_var = ++temp;
    print_properties("static const", &static_var, addr_offset);

    if (counter)
        static_const_value(counter - 1);
}

// here we test initialization of constexpr variable (compile time)
void constexpr_value(const short counter)
{
    constexpr short constexpr_var = constexpr_short;
    print_properties("constexpr", &constexpr_var, addr_offset);

    if (counter)
        constexpr_value(counter - 1);
}

// here we test initialization of static constexpr variable (compile time)
void static_constexpr_value(const short counter)
{
    static constexpr short static_constexpr_var = constexpr_short;
    print_properties("static constexpr", &static_constexpr_var, addr_offset);

    if (counter)
        static_constexpr_value(counter - 1);
}

// final test call this method from main()
void test_static_const()
{
    constexpr short counter = 2;

    const_value(counter);
    std::cout << std::endl;

    static_value(counter);
    std::cout << std::endl;

    static_const_value(counter);
    std::cout << std::endl;

    constexpr_value(counter);
    std::cout << std::endl;

    static_constexpr_value(counter);
    std::cout << std::endl;
}

Possible program output:

value \ address of const is               1 564
value \ address of const is               2 3D4
value \ address of const is               3 244

value \ address of static is              1 C58
value \ address of static is              1 C58
value \ address of static is              1 C58

value \ address of static const is        1 C64
value \ address of static const is        1 C64
value \ address of static const is        1 C64

value \ address of constexpr is           0 564
value \ address of constexpr is           0 3D4
value \ address of constexpr is           0 244

value \ address of static constexpr is    0 EA0
value \ address of static constexpr is    0 EA0
value \ address of static constexpr is    0 EA0

As you can see yourself constexpr is initilized multiple times (address is not the same) while static keyword ensures that initialization is performed only once.

If you use ng-model, you don't want to also use ng-checked. Instead just initialize the model variable to true. Normally you would do this in a controller that is managing your page (add one). In your fiddle I just did the initialization in an ng-init attribute for demonstration purposes.

http://jsfiddle.net/UTULc/

<div ng-app="">
  Send to Office: <input type="checkbox" ng-model="checked" ng-init="checked=true"><br/>
  <select id="transferTo" ng-disabled="checked">
    <option>Tech1</option>
    <option>Tech2</option>
  </select>
</div>

The problem was rJava wont install in RStudio (Version 1.0.136). The following worked for me (macOS Sierra version 10.12.6) (found here):

Step-1: Download and install javaforosx.dmg from here

Step-2: Next, run the command from inside RStudio:

install.packages("rJava", type = 'source')

seeing how the rules are fairly complicated, I'd suggest the following:

/^[a-z](\w*)[a-z0-9]$/i

match the whole string and capture intermediate characters. Then either with the string functions or the following regex:

/__/

check if the captured part has two underscores in a row. For example in Python it would look like this:

>>> import re
>>> def valid(s):
    match = re.match(r'^[a-z](\w*)[a-z0-9]$', s, re.I)
    if match is not None:
        return match.group(1).count('__') == 0
    return False

I like this way:

    @app.route("/summary")
    def summary():
        responseBody = { "message": "bla bla bla", "summary": make_summary() }
        return make_response(jsonify(responseBody), 200)

toolbar.setTitle(null);// remove the title

I also met this problem before. My situation was I didn't put all the 62 spring framework jars into the lib file (spring-framework-4.1.2.RELEASE edition), it did work. And then I also changed the 3.0.xsd into 2.5 or 3.1 for test, it all worked out. Of course, there are also other factors to affect your result.

Maybe below sample project helps you;

https://github.com/reinaldoarrosi/MaskedEditText

That project contains a view class call MaskedEditText. As first, you should add it in your project.

Then you add below xml part in res/values/attrs.xml file of project;

<resources>
    <declare-styleable name="MaskedEditText">
        <attr name="mask" format="string" />
        <attr name="placeholder" format="string" />
    </declare-styleable>
</resources>

Then you will be ready to use MaskedEditText view.

As last, you should add MaskedEditText in your xml file what you want like below;

<packagename.currentfolder.MaskedEditText
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/maskedEditText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:ems="10"
    android:text="5"
    app:mask="(999) 999-9999"
    app:placeholder="_" >

Of course that, you can use it programmatically.

After those steps, adding MaskedEditText will appear like below;

As programmatically, if you want to take it's text value as unmasked, you may use below row;

maskedEditText.getText(true);

To take masked value, you may send false value instead of true value in the getText method.

I think the easiest way to achieve this is by using set().

>>> x = [1,2,3,4,5,6,7,8,9,0]  
>>> y = [1,3,5,7,9]  
>>> list(set(x)- set(y))
[0, 2, 4, 6, 8]

I'd really recommend Scrapy.

Quote from a deleted answer:

• Scrapy crawling is fastest than mechanize because uses asynchronous operations (on top of Twisted).
• Scrapy has better and fastest support for parsing (x)html on top of libxml2.
• Scrapy is a mature framework with full unicode, handles redirections, gzipped responses, odd encodings, integrated http cache, etc.
• Once you are into Scrapy, you can write a spider in less than 5 minutes that download images, creates thumbnails and export the extracted data directly to csv or json.

Proxy can work in the following way.

Step1, configure client to use proxyHost:proxyPort.

Proxy is a TCP server that is listening on proxyHost:proxyPort. Browser opens connection with Proxy and sends Http request. Proxy parses this request and tries to detect "Host" header. This header will tell Proxy where to open connection.

Step 2: Proxy opens connection to the address specified in the "Host" header. Then it sends HTTP request to that remote server. Reads response.

Step 3: After response is read from remote HTTP server, Proxy sends the response through an earlier opened TCP connection with browser.

Schematically it will look like this:

Browser                            Proxy                     HTTP server
  Open TCP connection  
  Send HTTP request  ----------->                       
                                 Read HTTP header
                                 detect Host header
                                 Send request to HTTP ----------->
                                 Server
                                                      <-----------
                                 Read response and send
                   <-----------  it back to the browser

Preprocess your input CSV to replace blank entries with \N.

Attempt at a regex: s/,,/,\n,/g and s/,$/,\N/g

Good luck.

Make sure objects aren't null.

Having obj1 and obj2:

if(obj1 == null )
{
   return false;
}
return obj1.Equals( obj2 );

Per the MySQL docs DECLARE works only at the start of a BEGIN...END block as in a stored program.

Note that %in% returns a logical vector of TRUE and FALSE. To negate it, you can use ! in front of the logical statement:

SE_CSVLinelist_filtered <- filter(SE_CSVLinelist_clean, 
 !where_case_travelled_1 %in% 
   c('Outside Canada','Outside province/territory of residence but within Canada'))

Regarding your original approach with -c(...), - is a unary operator that "performs arithmetic on numeric or complex vectors (or objects which can be coerced to them)" (from help("-")). Since you are dealing with a character vector that cannot be coerced to numeric or complex, you cannot use -.

I had this other answer but this one, based on Jack's answer, is significantly faster might be preferred since it works asynchronously, although slightly slower.

public static class StringExtensionMethods
{
    public static IEnumerable<string> GetLines(this string str, bool removeEmptyLines = false)
    {
        using (var sr = new StringReader(str))
        {
            string line;
            while ((line = sr.ReadLine()) != null)
            {
                if (removeEmptyLines && String.IsNullOrWhiteSpace(line))
                {
                    continue;
                }
                yield return line;
            }
        }
    }
}

Usage:

input.GetLines()      // keeps empty lines

input.GetLines(true)  // removes empty lines

Test:

Action<Action> measure = (Action func) =>
{
    var start = DateTime.Now;
    for (int i = 0; i < 100000; i++)
    {
        func();
    }
    var duration = DateTime.Now - start;
    Console.WriteLine(duration);
};

var input = "";
for (int i = 0; i < 100; i++)
{
    input += "1 \r2\r\n3\n4\n\r5 \r\n\r\n 6\r7\r 8\r\n";
}

measure(() =>
    input.Split(new[] { "\r\n", "\r", "\n" }, StringSplitOptions.None)
);

measure(() =>
    input.GetLines()
);

measure(() =>
    input.GetLines().ToList()
);

Output:

00:00:03.9603894

00:00:00.0029996

00:00:04.8221971

Formatted :

$("input:checkbox[name=type]:checked").each(function(){
    yourArray.push($(this).val());
});

Hopefully, it will work.

Just for fun, here is a solution using ed which does not have the problem of not working on an empty file. You can put it into a shell script just like any other answer to this question.

ed Test <<EOF
a

.
0i
<added text>
.
1,+1 j
$ g/^$/d
wq
EOF

The above script adds the text to insert to the first line, and then joins the first and second line. To avoid ed exiting on error with an invalid join, it first creates a blank line at the end of the file and remove it later if it still exists.

Limitations: This script does not work if <added text> is exactly equal to a single period.

Because the range for floats is greater than that of integers -- returning an integer could overflow

It doesn't always need to be toolkit-dependent or one doesn't always need use the FontMetrics approach since it requires one to first obtain a graphics object which is absent in a web container or in a headless enviroment.

I have tested this in a web servlet and it does calculate the text width.

import java.awt.Font;
import java.awt.font.FontRenderContext;
import java.awt.geom.AffineTransform;

...

String text = "Hello World";
AffineTransform affinetransform = new AffineTransform();     
FontRenderContext frc = new FontRenderContext(affinetransform,true,true);     
Font font = new Font("Tahoma", Font.PLAIN, 12);
int textwidth = (int)(font.getStringBounds(text, frc).getWidth());
int textheight = (int)(font.getStringBounds(text, frc).getHeight());

Add the necessary values to these dimensions to create any required margin.

baos.toString(StandardCharsets.UTF_8);

Converts the buffer's contents into a string by decoding the bytes using the named charset.

You need to wrap the text in a div element and include the absolutely positioned element inside of it.

<div class="container">
    <div class="inner">
        <div class="full-height"></div>
        [Your text here]
    </div>
</div>

Css:

.inner: { position: relative; height: auto; }
.full-height: { height: 100%; }

Setting the inner div's position to relative makes the absolutely position elements inside of it base their position and height on it rather than on the .container div, which has a fixed height. Without the inner, relatively positioned div, the .full-height div will always calculate its dimensions and position based on .container.

You can use == to compare with a zero value composite literal because all fields are comparable:

if (Session{}) == session  {
    fmt.Println("is zero value")
}

playground example

Because of a parsing ambiguity, parentheses are required around the composite literal in the if condition.

The use of == above applies to structs where all fields are comparable. If the struct contains a non-comparable field (slice, map or function), then the fields must be compared one by one to their zero values.

An alternative to comparing the entire value is to compare a field that must be set to a non-zero value in a valid session. For example, if the player id must be != "" in a valid session, use

if session.playerId == "" {
    fmt.Println("is zero value")
}

Before abc was introduced you would see this frequently.

class Base(object):
    def go(self):
        raise NotImplementedError("Please Implement this method")


class Specialized(Base):
    def go(self):
        print "Consider me implemented"

Its quite simple

1) just copy your images and paste in drawable folder.

2) when you paste image(for eg"mdpi) in drawable folder a popup window will appear asking folder name add -mdpi .

3)Do it for all(hdpi,xhdpi,xxhdpi).

I just added one link that you can check out if have any doubt.

http://www.androidwarriors.com/2015/07/android-studio-drawable-folders.html

Maybe the solution someone is looking for is this:

Response.Redirect("/Sucesso")

This work when used in the View as well.

Another way is to use constant pattern matching:

if (nullableBool is true) {}
if (nullableBool is false) {}
if (nullableBool is null) {}

Unlike the operator ==, when reading the code, this will distinguish the nullable type check from ordinary "code with a smell".

On a Oracle JDK, we have a command called jmap (available in the bin folder of Java Home). usage of the command comes as follows

jmap (option) (pid)

Example: jmap -dump:live,format=b,file=heap.bin (pid)

There is a simple solution for you called unique_together which does exactly what you want.

For example:

class MyModel(models.Model):
  field1 = models.CharField(max_length=50)
  field2 = models.CharField(max_length=50)

  class Meta:
    unique_together = ('field1', 'field2',)

And in your case:

class Volume(models.Model):
  id = models.AutoField(primary_key=True)
  journal_id = models.ForeignKey(Journals, db_column='jid', null=True, verbose_name = "Journal")
  volume_number = models.CharField('Volume Number', max_length=100)
  comments = models.TextField('Comments', max_length=4000, blank=True)

  class Meta:
    unique_together = ('journal_id', 'volume_number',)

SELECT TIMESTAMPDIFF(HOUR,NOW(),'2013-05-15 10:23:23')
   calculates difference in hour.(for days--> you have to define day replacing hour
SELECT DATEDIFF('2012-2-2','2012-2-1')

SELECT TO_DAYS ('2012-2-2')-TO_DAYS('2012-2-1')

Go to the .project file of your project make sure it display the same name as displayed in project folder. if not change the name. it will work.

import vs. include

The primary purpose of an import is to import a namespace. A more common use of the XSD import statement is to import a namespace which appears in another file. You might be gathering the namespace information from the file, but don't forget that it's the namespace that you're importing, not the file (don't confuse an import statement with an include statement).

Another area of confusion is how to specify the location or path of the included .xsd file: An XSD import statement has an optional attribute named schemaLocation but it is not necessary if the namespace of the import statement is at the same location (in the same file) as the import statement itself.

When you do chose to use an external .xsd file for your WSDL, the schemaLocation attribute becomes necessary. Be very sure that the namespace you use in the import statement is the same as the targetNamespace of the schema you are importing. That is, all 3 occurrences must be identical:

WSDL:

xs:import namespace="urn:listing3" schemaLocation="listing3.xsd"/>

XSD:

<xsd:schema targetNamespace="urn:listing3"
            xmlns:xsd="http://www.w3.org/2001/XMLSchema"> 

Another approach to letting know the WSDL about the XSD is through Maven's pom.xml:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>xmlbeans-maven-plugin</artifactId>
  <executions>
    <execution>
      <id>generate-sources-xmlbeans</id>
      <phase>generate-sources</phase>
      <goals>
    <goal>xmlbeans</goal>
      </goals>
    </execution>
  </executions>
  <version>2.3.3</version>
  <inherited>true</inherited>
  <configuration>
    <schemaDirectory>${basedir}/src/main/xsd</schemaDirectory>
  </configuration>
</plugin>

You can read more on this in this great IBM article. It has typos such as xsd:import instead of xs:import but otherwise it's fine.

Actually, the difference between hibernate save() and persist() methods depends on generator class we are using.
If our generator class is assigned, then there is no difference between save() and persist() methods. Because generator ‘assigned’ means, as a programmer we need to give the primary key value to save in the database right [ Hope you know this generators concept ] In case of other than assigned generator class, suppose if our generator class name is Increment means hibernate itself will assign the primary key id value into the database right [other than assigned generator, hibernate only used to take care the primary key id value remember], so in this case if we call save() or persist() method, then it will insert the record into the database normally.
But here, thing is, save() method can return that primary key id value which is generated by hibernate and we can see it by
long s = session.save(k);
In this same case, persist() will never give any value back to the client, return type void.
persist() also guarantees that it will not execute an INSERT statement if it is called outside of transaction boundaries.
whereas in save(), INSERT happens immediately, no matter if you are inside or outside of a transaction.

this.options[this.selectedIndex].innerText

Yes. Or, rather, no.

Er, I mean, it doesn't matter. Use the one that makes sense for your particular project. PX and EM or both equally valid but will behave a bit different depending on your overall page's CSS architecture.

UPDATE:

To clarify, I'm stating that usually it likely doesn't matter which you use. At times, you may specifically want to choose one over the other. EMs are nice if you can start from scratch and want to use a base font size and make everything relative to that.

PXs are often needed when you're retrofitting a redesign onto an existing code base and need the specificity of px to prevent bad nesting issues.

What's the first part of your Subversion repository URL?

• If your URL looks like: http://subversion/repos/, then you're probably going over Port 80.
• If your URL looks like: https://subversion/repos/, then you're probably going over Port 443.
• If your URL looks like: svn://subversion/, then you're probably going over Port 3690.
• If your URL looks like: svn+ssh://subversion/repos/, then you're probably going over Port 22.
• If your URL contains a port number like: http://subversion/repos:8080, then you're using that port.

I can't guarantee the first four since it's possible to reconfigure everything to use different ports, of if you go through a proxy of some sort.

If you're using a VPN, you may have to configure your VPN client to reroute these to their correct ports. A lot of places don't configure their correctly VPNs to do this type of proxying. It's either because they have some sort of anal-retentive IT person who's being overly security conscious, or because they simply don't know any better. Even worse, they'll give you a client where this stuff can't be reconfigured.

The only way around that is to log into a local machine over the VPN, and then do everything from that system.

You can use the option -C (or --directory if you prefer long options) to give the target directory of your choice in case you are using the Gnu version of tar. The directory should exist:

mkdir foo
tar -xzf bar.tar.gz -C foo

If you are not using a tar capable of extracting to a specific directory, you can simply cd into your target directory prior to calling tar; then you will have to give a complete path to your archive, of course. You can do this in a scoping subshell to avoid influencing the surrounding script:

mkdir foo
(cd foo; tar -xzf ../bar.tar.gz)  # instead of ../ you can use an absolute path as well

Or, if neither an absolute path nor a relative path to the archive file is suitable, you also can use this to name the archive outside of the scoping subshell:

TARGET_PATH=a/very/complex/path/which/might/even/be/absolute
mkdir -p "$TARGET_PATH"
(cd "$TARGET_PATH"; tar -xzf -) < bar.tar.gz

The main function can have two parameters, argc and argv. argc is an integer (int) parameter, and it is the number of arguments passed to the program.

The program name is always the first argument, so there will be at least one argument to a program and the minimum value of argc will be one. But if a program has itself two arguments the value of argc will be three.

Parameter argv points to a string array and is called the argument vector. It is a one dimensional string array of function arguments.

The reason why your image is resizing which is because it is fluid. You have two ways to do it:

1. Either give a fixed dimension to your image using CSS like:

   .carousel-inner > .item > img {
     width:640px;
     height:360px;
   }

2. A second way to can do this:

   .carousel {
     width:640px;
     height:360px;
   }

You can't, because IEnumerable doesn't have an index at all... if you are sure your enumerable has less than int.MaxValue elements (or long.MaxValue if you use a long index), you can:

1. Don't use foreach, and use a for loop, converting your IEnumerable to a generic enumerable first:

   var genericList = list.Cast<object>();
   for(int i = 0; i < genericList.Count(); ++i)
   {
      var row = genericList.ElementAt(i);
      /* .... */
   }
   

2. Have an external index:

   int i = 0;
   foreach(var row in list)
   {
      /* .... */
      ++i;
   }
   

3. Get the index via Linq:

   foreach(var rowObject in list.Cast<object>().Select((r, i) => new {Row=r, Index=i}))
   {
     var row = rowObject.Row;
     var i = rowObject.Index;
     /* .... */    
   }
   

In your case, since your IEnumerable is not a generic one, I'd rather use the foreach with external index (second method)... otherwise, you may want to make the Cast<object> outside your loop to convert it to an IEnumerable<object>.

Your datatype is not clear from the question, but I'm assuming object since it's an items source (it could be DataGridRow)... you may want to check if it's directly convertible to a generic IEnumerable<object> without having to call Cast<object>(), but I'll make no such assumptions.

All this said:

The concept of an "index" is foreign to an IEnumerable. An IEnumerable can be potentially infinite. In your example, you are using the ItemsSource of a DataGrid, so more likely your IEnumerable is just a list of objects (or DataRows), with a finite (and hopefully less than int.MaxValue) number of members, but IEnumerable can represent anything that can be enumerated (and an enumeration can potentially never end).

Take this example:

public static IEnumerable InfiniteEnumerable()
{
  var rnd = new Random();
  while(true)
  {
    yield return rnd.Next();
  }
}

So if you do:

foreach(var row in InfiniteEnumerable())
{
  /* ... */
}

Your foreach will be infinite: if you used an int (or long) index, you'll eventually overflow it (and unless you use an unchecked context, it'll throw an exception if you keep adding to it: even if you used unchecked, the index would be meaningless also... at some point -when it overflows- the index will be the same for two different values).

So, while the examples given work for a typical usage, I'd rather not use an index at all if you can avoid it.

I actually built a Chrome extension that does exactly this, and for all web pages. The source code is on GitHub.

I find three bugs with Trello's approach, which I know because I've faced them myself :)

The copy doesn't work in these scenarios:

1. If you already have Ctrl pressed and then hover a link and hit C, the copy doesn't work.
2. If your cursor is in some other text field in the page, the copy doesn't work.
3. If your cursor is in the address bar, the copy doesn't work.

I solved #1 by always having a hidden span, rather than creating one when user hits Ctrl/Cmd.

I solved #2 by temporarily clearing the zero-length selection, saving the caret position, doing the copy and restoring the caret position.

I haven't found a fix for #3 yet :) (For information, check the open issue in my GitHub project).

No, you can't instantite an abstract class.We instantiate only anonymous class.In abstract class we declare abstract methods and define concrete methods only.

I think @hnovick's solution is a cool one if you dont have table-less models. This solution would work in development mode as well

My approach is subtly different though -

ActiveRecord::Base.connection.tables.map{|x|x.classify.safe_constantize}.compact

classify is well supposed to give you the name of the class from a string properly. safe_constantize ensures that you can turn it into a class safely without throwing an exception. This is needed in case you have database tables which are not models. compact so that any nils in the enumeration are removed.

You have at least 5 different ways to view the commit you currently have checked out into your working copy during a git bisect session (note that options 1-4 will also work when you're not doing a bisect):

1. git show.
2. git log -1.
3. Bash prompt.
4. git status.
5. git bisect visualize.

I'll explain each option in detail below.

Option 1: git show

As explained in this answer to the general question of how to determine which commit you currently have checked-out (not just during git bisect), you can use git show with the -s option to suppress patch output:

$ git show --oneline -s
a9874fd Merge branch 'epic-feature'

Option 2: git log -1

You can also simply do git log -1 to find out which commit you're currently on.

$ git log -1 --oneline
c1abcde Add feature-003

Option 3: Bash prompt

In Git version 1.8.3+ (or was it an earlier version?), if you have your Bash prompt configured to show the current branch you have checked out into your working copy, then it will also show you the current commit you have checked out during a bisect session or when you're in a "detached HEAD" state. In the example below, I currently have c1abcde checked out:

# Prompt during a bisect
user ~ (c1abcde...)|BISECTING $

# Prompt at detached HEAD state 
user ~ (c1abcde...) $

Option 4: git status

Also as of Git version 1.8.3+ (and possibly earlier, again not sure), running git status will also show you what commit you have checked out during a bisect and when you're in detached HEAD state:

$ git status
# HEAD detached at c1abcde <== RIGHT HERE

Option 5: git bisect visualize

Finally, while you're doing a git bisect, you can also simply use git bisect visualize or its built-in alias git bisect view to launch gitk, so that you can graphically view which commit you are on, as well as which commits you have marked as bad and good so far. I'm pretty sure this existed well before version 1.8.3, I'm just not sure in which version it was introduced:

git bisect visualize 
git bisect view # shorter, means same thing

As mentioned, Function.bind() lets you specify the context that the function will execute in (that is, it lets you pass in what object the this keyword will resolve to in the body of the function.

A couple of analogous toolkit API methods that perform a similar service:

jQuery.proxy()

Dojo.hitch()

To really get this clear, here's my for-beginners answer: You inputed the arguments in the wrong order.
A keyword argument has this style:

nullable=True, unique=False

A fixed parameter should be defined: True, False, etc. A non-keyword argument is different:

name="Ricardo", fruit="chontaduro" 

This syntax error asks you to first put name="Ricardo" and all of its kind (non-keyword) before those like nullable=True.

python keywordnon-keywordsyntax-error

spinner_button.setOnItemSelectedListener(new OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?>arg0, View view, int arg2, long arg3) {

            String selected_val=spinner_button.getSelectedItem().toString();

            Toast.makeText(getApplicationContext(), selected_val ,
                    Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub

        }
    });

}

Here is a code to draw a fill elipse, you can use the same method but replacing de xcenter and y center with radius

void drawFilledelipse(GLfloat x, GLfloat y, GLfloat xcenter,GLfloat ycenter) {
    int i;
    int triangleAmount = 20; //# of triangles used to draw circle

    //GLfloat radius = 0.8f; //radius
    GLfloat twicePi = 2.0f * PI;

    glBegin(GL_TRIANGLE_FAN);
    glVertex2f(x, y); // center of circle
    for (i = 0; i <= triangleAmount; i++) {
        glVertex2f(
            x + ((xcenter+1)* cos(i * twicePi / triangleAmount)),
            y + ((ycenter-1)* sin(i * twicePi / triangleAmount))
        );
    }
    glEnd();
}

void listBox1_MouseDoubleClick(object sender, MouseEventArgs e)
{
    int index = this.listBox1.IndexFromPoint(e.Location);
    if (index != System.Windows.Forms.ListBox.NoMatches)
    {
        MessageBox.Show(index.ToString());
    }
}

This should work...check

For images if your using Web Pages v2 use the WebImage Class

var webImage = new System.Web.Helpers.WebImage(Request.Files[0].InputStream);
byte[] imgByteArray = webImage.GetBytes();

The .before argument in dplyr::add_row can be used to specify the row.

dplyr::add_row(
  cars,
  speed = 0,
  dist = 0,
  .before = 3
)
#>    speed dist
#> 1      4    2
#> 2      4   10
#> 3      0    0

Just as normal, using data-original-title:

Html:

<div rel='tooltip' data-original-title='<h1>big tooltip</h1>'>Visible text</div>

Javascript:

$("[rel=tooltip]").tooltip({html:true});

The html parameter specifies how the tooltip text should be turned into DOM elements. By default Html code is escaped in tooltips to prevent XSS attacks. Say you display a username on your site and you show a small bio in a tooltip. If the html code isn't escaped and the user can edit the bio themselves they could inject malicious code.

for i, row in df.iterrows():
    if <something>:
        df.at[i, 'ifor'] = x
    else:
        df.at[i, 'ifor'] = y

You don't need arrays for this. Try something like:

ActiveSheet.Range("$A$1:$A$" & LastRow).RemoveDuplicates Columns:=1, Header:=xlYes

If there's no header, change accordingly.

EDIT: Here's the traditional method, which takes advantage of the fact that each item in a Collection must have a unique key:

Sub test()
Dim ws As Excel.Worksheet
Dim LastRow As Long
Dim coll As Collection
Dim cell As Excel.Range
Dim arr() As String
Dim i As Long

Set ws = ActiveSheet
With ws
    LastRow = .Range("C" & .Rows.Count).End(xlUp).Row
    Set coll = New Collection
    For Each cell In .Range("C4:C" & LastRow)
        On Error Resume Next
        coll.Add cell.Value, CStr(cell.Value)
        On Error GoTo 0
    Next cell
    ReDim arr(1 To coll.Count)
    For i = LBound(arr) To UBound(arr)
        arr(i) = coll(i)
        'to show in Immediate Window
        Debug.Print arr(i)
    Next i
End With
End Sub

A query string is an array of parameters sent to a web page.

This url: http://page.asp?x=1&y=hello

Request.QueryString[0] is the same as 
Request.QueryString["x"] and holds a string value "1"

Request.QueryString[1] is the same as 
Request.QueryString["y"] and holds a string value "hello"

If you are willing to use c++11 you can utilize user-defined string literals and define two function templates that overload the plus operator for a std::string object and any other object. The only pitfall is not to overload the plus operators of std::string, otherwise the compiler doesn't know which operator to use. You can do this by using the template std::enable_if from type_traits. After that strings behave just like in Java or C#. See my example implementation for details.

this is a generic method, you can use everywhere

const isBetween = (num1,num2,value) => value > num1 && value < num2 

You can use matplotlib to plot the histogram and the PDF (as in the link in @MrE's answer). For fitting and for computing the PDF, you can use scipy.stats.norm, as follows.

import numpy as np
from scipy.stats import norm
import matplotlib.pyplot as plt


# Generate some data for this demonstration.
data = norm.rvs(10.0, 2.5, size=500)

# Fit a normal distribution to the data:
mu, std = norm.fit(data)

# Plot the histogram.
plt.hist(data, bins=25, density=True, alpha=0.6, color='g')

# Plot the PDF.
xmin, xmax = plt.xlim()
x = np.linspace(xmin, xmax, 100)
p = norm.pdf(x, mu, std)
plt.plot(x, p, 'k', linewidth=2)
title = "Fit results: mu = %.2f,  std = %.2f" % (mu, std)
plt.title(title)

plt.show()

Here's the plot generated by the script:

you said that:

`mony = float(1234.5)
print(money)      #output is 1234.5
'${:,.2f}'.format(money)
print(money)

did not work.... Have you coded exactly that way? This should work (see the little difference):

money = float(1234.5)      #next you used format without printing, nor affecting value of "money"
amountAsFormattedString = '${:,.2f}'.format(money)
print( amountAsFormattedString )

Just a heads up, I couldn't get these solutions to work on Material UI components. Looks like they don't have the current property.

I just added an empty div amongst my components and set the ref prop on that.

The equivalent to the accepted answer in jQuery 1.11:

$(window).on("beforeunload", function () {
    return "Please don't leave me!";
});

JSFiddle example

altCognito's answer used the unload event, which happens too late for JavaScript to abort the navigation.

To convert tuples to list

(Commas were missing between the tuples in the given question, it was added to prevent error message)

Method 1:

level1 = (
     (1,1,1,1,1,1),
     (1,0,0,0,0,1),
     (1,0,0,0,0,1),
     (1,0,0,0,0,1),
     (1,0,0,0,0,1),
     (1,1,1,1,1,1))

level1 = [list(row) for row in level1]

print(level1)

Method 2:

level1 = map(list,level1)

print(list(level1))

Method 1 took --- 0.0019991397857666016 seconds ---

Method 2 took --- 0.0010001659393310547 seconds ---

https://github.com/blueimp/JavaScript-Load-Image is a modern javascript library that can not only extract the exif orientation flag - it can also correctly mirror/rotate JPEG images on the client side.

I just solved the same problem with this library: JS Client-Side Exif Orientation: Rotate and Mirror JPEG Images

Here is how I fixed mine:

1. find the location where your jre is installed. in my case, it was located at C:\Program Files\Java\jdk1.7.0_10

2. copy the jre folder and paste it where your eclipse files are located (where eclipse.exe is located).

when you download eclipse, you get a .zip package containing eclipse.exe and all the other files needed to run eclipse but it is missing the jre files. so all you need to do is to find where jre folder is located on your hard drive and add it to the rest of the eclipse package.

This code works fine, but the only issue is if the file format is other than specified options, it shows an alert message but it displays the file name while it should be neglecting it.

$('#ff2').change(
                function () {
                    var fileExtension = ['jpeg', 'jpg', 'pdf'];
                    if ($.inArray($(this).val().split('.').pop().toLowerCase(), fileExtension) == -1) {
                        alert("Only '.jpeg','.jpg','.pdf' formats are allowed.");
                        return false; }
});

Using 'ServerSocket' class we can identify whether given port is in use or free. ServerSocket provides a constructor that take an integer (which is port number) as argument and initialise server socket on the port. If ServerSocket throws any IO Exception, then we can assume this port is already in use.

Following snippet is used to get all available ports.

for (int port = 1; port < 65535; port++) {
         try {
                  ServerSocket socket = new ServerSocket(port);
                  socket.close();
                  availablePorts.add(port);
         } catch (IOException e) {

         }
}

Your session status are set once you start a session, and by default, take the current GLOBAL value.

If you disconnected after you did SET @@GLOBAL.wait_timeout=300, then subsequently reconnected, you'd see

SHOW SESSION VARIABLES LIKE "%wait%";

Result: 300

Similarly, at any time, if you did

mysql> SET session wait_timeout=300;

You'd get

mysql> SHOW SESSION VARIABLES LIKE 'wait_timeout';

+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| wait_timeout  | 300   |

The internal storage is referred to as "external storage" in the API.

As mentioned in the Environment documentation

Note: don't be confused by the word "external" here. This directory can better be thought as media/shared storage. It is a filesystem that can hold a relatively large amount of data and that is shared across all applications (does not enforce permissions). Traditionally this is an SD card, but it may also be implemented as built-in storage in a device that is distinct from the protected internal storage and can be mounted as a filesystem on a computer.

To distinguish whether "Environment.getExternalStorageDirectory()" actually returned physically internal or external storage, call Environment.isExternalStorageEmulated(). If it's emulated, than it's internal. On newer devices that have internal storage and sdcard slot Environment.getExternalStorageDirectory() will always return the internal storage. While on older devices that have only sdcard as a media storage option it will always return the sdcard.

There is no way to retrieve all storages using current Android API.

I've created a helper based on Vitaliy Polchuk's method in the answer below

How can I get the list of mounted external storage of android device

NOTE: starting KitKat secondary storage is accessible only as READ-ONLY, you may want to check for writability using the following method

/**

 * @param volume
 *            StorageVolume to check
 * @return true, if volume is mounted read-only
 */
public static boolean isReadOnly(@NonNull final StorageVolume volume) {

        // is a primary storage, check mounted state by Environment
        return android.os.Environment.getExternalStorageState().equals(
                android.os.Environment.MEDIA_MOUNTED_READ_ONLY);
    } else {
        if (volume.getType() == Type.USB) {
            return volume.isReadOnly();
        }
        //is not a USB storagem so it's read-only if it's mounted read-only or if it's a KitKat device
        return volume.isReadOnly() || Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;
    }
}

You could also make it a post-build step. Setup a new configuration which is "Deploy" in addition to Debug and Release, and then have the post-build step copy over the correct web.config.

We use automated builds for all of our projects, and with those the build script updates the web.config file to point to the correct location. But that won't help you if you are doing everything from VS.

This can be done in following ways:

from __future__ import print_function
str = "Hello World !!"
for char in str:
    mm = int(char.encode('hex'), 16)
    print(hex(mm), sep=':', end=' ' )

The output of this will be in hex as follows:

0x48 0x65 0x6c 0x6c 0x6f 0x20 0x57 0x6f 0x72 0x6c 0x64 0x20 0x21 0x21

You can use BIGINT as follows:

CREATE TABLE user_reg (
user_id INT NOT NULL AUTO_INCREMENT,
identifier INT,
phone_number CHAR(11) NOT NULL,
verified TINYINT UNSIGNED NOT NULL,
reg_time BIGINT,
last_active_time BIGINT,
PRIMARY KEY (user_id),
INDEX (phone_number, user_id, identifier)
   );

This line:

layout = (LinearLayout) findViewById(R.id.statsviewlayout);

Looks for the "statsviewlayout" id in your current 'contentview'. Now you've set that here:

setContentView(new GraphTemperature(getApplicationContext()));

And i'm guessing that new "graphTemperature" does not set anything with that id.

It's a common mistake to think you can just find any view with findViewById. You can only find a view that is in the XML (or appointed by code and given an id).

The nullpointer will be thrown because the layout you're looking for isn't found, so

layout.addView(buyButton);

Throws that exception.

addition: Now if you want to get that view from an XML, you should use an inflater:

layout = (LinearLayout) View.inflate(this, R.layout.yourXMLYouWantToLoad, null);

assuming that you have your linearlayout in a file called "yourXMLYouWantToLoad.xml"

I have uninstalled 8.0.19 (64) and installed 8.0.18 (64 bit) and now it Opens.

    wp_register_script('custom-js',WP_PLUGIN_URL.'/PLUGIN_NAME/js/custom.js',array(),NULL,true);
    wp_enqueue_script('custom-js');

    $wnm_custom = array( 'template_url' => get_bloginfo('template_url') );
    wp_localize_script( 'custom-js', 'wnm_custom', $wnm_custom );

and in custom.js

alert(wnm_custom.template_url);

Can I control the HTTP headers sent by window.open (cross browser)?

No

If not, can I somehow window.open a page that then issues my request with custom headers inside its popped-up window?

• You can request a URL that triggers a server side program which makes the request with arbitrary headers and then returns the response
• You can run JavaScript (probably saying goodbye to Progressive Enhancement) that uses XHR to make the request with arbitrary headers (assuming the URL fits within the Same Origin Policy) and then process the result in JS.

I need some cunning hacks...

It might help if you described the problem instead of asking if possible solutions would work.

Escaping strings can be tricky - especially if you want to take unicode into account. I suppose XML is one of the simpler formats/languages to escape but still. I would recommend taking a look at the StringEscapeUtils class in Apache Commons Lang, and its handy escapeXml method.

When maven is working outside of Eclipse, but giving this error after a JDK change, Go to your Maven Run Configuration, and at the bottom of the Main page, there's a 'Maven Runtime' option. Mine was using the Embedded Maven, so after switching it to use my external maven, it worked.

You can also use flexbox, but you'd have to add a parent div that covers div#top and div#term-defs. So the HTML looks like this:

    #content {_x000D_
        width: 100%;_x000D_
        height: 100%;_x000D_
        display: flex;_x000D_
        flex-direction: column;_x000D_
    }_x000D_
_x000D_
    #term-defs {_x000D_
        flex-grow: 1;_x000D_
        overflow: auto;_x000D_
    } 

    <body>_x000D_
        <div id="content">_x000D_
            <div id="top">_x000D_
                <a href="#A">A</a> |_x000D_
                <a href="#B">B</a> |_x000D_
                <a href="#Z">Z</a>_x000D_
            </div>_x000D_
    _x000D_
            <div id="term-defs">_x000D_
                <dl>_x000D_
                    <span id="A"></span>_x000D_
                    <dt>foo</dt>_x000D_
                    <dd>This is the sound made by a fool</dd>_x000D_
                    <!-- and so on ... -->_x000D_
                </dl>_x000D_
            </div>_x000D_
        </div>_x000D_
    </body>

flex-grow ensures that the div's size is equal to the remaining size.

You could do the same without flexbox, but it would be more complicated to work out the height of #term-defs (you'd have to know the height of #top and use calc(100% - 999px) or set the height of #term-defs directly).
With flexbox dynamic sizes of the divs are possible.

One difference is that the scrollbar only appears on the term-defs div.

If you want to move from one origin to another and also keep a backup of your current origin on your local machine you could use these steps:

1. First locally go to the (git)folder you want to move over
2. Create the new repository online This step creates a repository where we can push code to

Now in the folder do

git remote get-url origin

The above command gives the current remote origin url, useful to set the origin back to in the last step

git remote set-url origin [email protected]:folder/newrepo.git

The above command sets the remote origin to the new location

git push --set-upstream origin develop

The above command pushes the current active local branch to remote with branchname develop. Of course it preserves all history as with git all history is also pushed.

git remote set-url origin <original old origin>

The above command sets back the remote origin to your current origin: you want this because you are in your existing folder and you probably do not want to mix up your current local folder name with the new folder you are going to create for cloning the repo you just pushed to.

Hope this helps,

How this works?

Example: http://jsfiddle.net/953Yj/

<div class="center">
    Lorem ipsum
</div>

.center{
    position:absolute;
    height: X px;
    width: Y px;
    left:50%;
    top:50%;
    margin-top:- X/2 px;
    margin-left:- Y/2 px;
}

• X would your your height.
• Y would be your width.

To position the div vertically and horizontally, divide X and Y by 2.

None of the answers mentioned above worked for me. I am using Tomcat 9 in my Eclipse IDE. Hence I tried the following steps on my Eclipse Neon.

Step #1: Click on Servers tab to see your server. In my case, it looks like the following:

Step #2: Right click on the server, select Properties, you will see the following window. Click on Switch Location, it will change the location to the one shown in the image below from the default one.Click on Apply and then OK to close the window.

Step #3 Double click on the Tomcat Server which will open the Overview option as shown in the image below. The Server Locations part was active for me when I did (it's shown inactive in the image because I already did that at my end and I have my server running) that and I selected the second radio button option which is Use Tomcat installation (takes control of Tomcat installation). I then closed this option , saved the changes when prompted and started my server. It started working fine.

ConfigurationSettings.AppSettings is obsolete, you should use ConfigurationManager.AppSettings instead (you will need to add a reference to System.Configuration)

int value = Int32.Parse(ConfigurationManager.AppSettings["StartingMonthColumn"]);

If you still have problems reading in your app settings then check that your app.config file is named correctly. Specifically, it should be named according to the executing assembly i.e. MyApp.exe.config, and should reside in the same directory as MyApp.exe.

Insert date in the following format yyyy-MM-dd example,

INSERT INTO `PROGETTO`.`ALBERGO`(`ID`, `nome`, `viale`, `num_civico`, `data_apertura`, `data_chiusura`, `orario_apertura`, `orario_chiusura`, `posti_liberi`, `costo_intero`, `costo_ridotto`, `stelle`, `telefono`, `mail`, `web`, `Nome-paese`, `Comune`) 
VALUES(0, 'Hotel Centrale', 'Via Passo Rolle', '74', '2012-05-01', '2012-09-31', '06:30', '24:00', 80, 50, 25, 3, '43968083', '[email protected]', 'http://www.hcentrale.it/', 'Trento', 'TN')

As a rule of thumb, the safest bet towards making your document be treated properly by all web servers, proxies, and client browsers, is probably the following:

1. Use the application/xml content type
2. Include a character encoding in the content type, probably UTF-8
3. Include a matching character encoding in the encoding attribute of the XML document itself.

In terms of the RFC 3023 spec, which some browsers fail to implement properly, the major difference in the content types is in how clients are supposed to treat the character encoding, as follows:

For application/xml, application/xml-dtd, application/xml-external-parsed-entity, or any one of the subtypes of application/xml such as application/atom+xml, application/rss+xml or application/rdf+xml, the character encoding is determined in this order:

1. the encoding given in the charset parameter of the Content-Type HTTP header
2. the encoding given in the encoding attribute of the XML declaration within the document,
3. utf-8.

For text/xml, text/xml-external-parsed-entity, or a subtype like text/foo+xml, the encoding attribute of the XML declaration within the document is ignored, and the character encoding is:

1. the encoding given in the charset parameter of the Content-Type HTTP header, or
2. us-ascii.

Most parsers don't implement the spec; they ignore the HTTP Context-Type and just use the encoding in the document. With so many ill-formed documents out there, that's unlikely to change any time soon.

\S matches anything but a whitespace, according to this reference.

As Cody and Brett mentioned, you could reduce VBA slowdown with sensible use of Redim Preserve. Brett suggested Mod to do this.

You can also use a user defined Type and Sub to do this. Consider my code below:

Public Type dsIntArrayType
   eElems() As Integer
   eSize As Integer
End Type

Public Sub PushBackIntArray( _
    ByRef dsIntArray As dsIntArrayType, _
    ByVal intValue As Integer)

    With dsIntArray
    If UBound(.eElems) < (.eSize + 1) Then
        ReDim Preserve .eElems(.eSize * 2 + 1)
    End If
    .eSize = .eSize + 1
    .eElems(.eSize) = intValue
    End With

End Sub

This calls ReDim Preserve only when the size has doubled. The member variable eSize keeps track of the actual data size of eElems. This approach has helped me improve performance when final array length is not known until run time.

Hope this helps others too.

From Python you can do directly using below code

import subprocess
proc = subprocess.check_output('C:\Windows\System32\cmd.exe /k %windir%\System32\\reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 0 /f' ,stderr=subprocess.STDOUT,shell=True)
    print(str(proc))

in first parameter just executed User Account setting you may customize with yours.

Node.js 10 supports ECMAScript modules, where __dirname and __filename are no longer available.

Then to get the path to the current ES module one has to use:

import { fileURLToPath } from 'url';

const __filename = fileURLToPath(import.meta.url);

And for the directory containing the current module:

import { dirname } from 'path';
import { fileURLToPath } from 'url';

const __dirname = dirname(fileURLToPath(import.meta.url));

I needed this in a function on SQL server and adjusted Patrick's answer a bit.

declare @dossierId int = 123
declare @padded_id varchar(7)


set @padded_id = REPLACE(
              SPACE(7 - LEN(@dossierId)) + convert(varchar(7), @dossierId), 
              SPACE(1),  
              '0') 

SELECT @dossierId as '@dossierId'
      ,SPACE(LEN(@dossierId)) + convert(varchar(7)
      ,@dossierId) as withSpaces
      ,@padded_id as '@padded_id'

Copying to the clipboard is a tricky task to do in Javascript in terms of browser compatibility. The best way to do it is using a small flash. It will work on every browser. You can check it in this article.

Here's how to do it for Internet Explorer:

function copy (str)
{
    //for IE ONLY!
    window.clipboardData.setData('Text',str);
}

ngOnInit() is called right after the directive's data-bound properties have been checked for the first time, and before any of its children have been checked. It is invoked only once when the directive is instantiated.

ngAfterViewInit() is called after a component's view, and its children's views, are created. Its a lifecycle hook that is called after a component's view has been fully initialized.

If your class is non-activity class, and creating an instance of it from the activiy, you can pass an instance of context via constructor of the later as follows:

class YourNonActivityClass{

// variable to hold context
private Context context;

//save the context recievied via constructor in a local variable

public YourNonActivityClass(Context context){
    this.context=context;
}

}

You can create instance of this class from the activity as follows:

new YourNonActivityClass(this);

I believe this is what you are looking for,

Server version:

pg_config --version

Client version:

psql --version

If you have VS 2013, you have to go to: %LOCALAPPDATA%\Microsoft\VisualStudio\12.0 then rename the ComponentModelCache folder.

I checked in angular 2 seed how it works.

You can use express-history-api-fallback to redirect automatically when a page is reload.

I think it's the most elegant way to resolve this problem IMO.

Catching Exception will catch a RuntimeException

See: Multiple-line-syntax

It also support variables in multiline string, for example:

String name="zzg";
String lines = ""/**~!{
    SELECT * 
        FROM user
        WHERE name="$name"
}*/;
System.out.println(lines);

Output:

SELECT * 
    FROM user
    WHERE name="zzg"

Why do you not use the java functionality for that:

If your numbers are small (smaller than yours) you could use: Integer.parseInt(hex, 16) to convert a Hex - String into an integer.

  String hex = "ff"
  int value = Integer.parseInt(hex, 16);  

For big numbers like yours, use public BigInteger(String val, int radix)

  BigInteger value = new BigInteger(hex, 16);

@See JavaDoc:

• Integer.parseInt(String value, int radix)
• BigInteger(String value, int radix)

.NET Core 2.0 has Path.GetRelativePath, else, use this.

/// <summary>
/// Creates a relative path from one file or folder to another.
/// </summary>
/// <param name="fromPath">Contains the directory that defines the start of the relative path.</param>
/// <param name="toPath">Contains the path that defines the endpoint of the relative path.</param>
/// <returns>The relative path from the start directory to the end path or <c>toPath</c> if the paths are not related.</returns>
/// <exception cref="ArgumentNullException"></exception>
/// <exception cref="UriFormatException"></exception>
/// <exception cref="InvalidOperationException"></exception>
public static String MakeRelativePath(String fromPath, String toPath)
{
    if (String.IsNullOrEmpty(fromPath)) throw new ArgumentNullException("fromPath");
    if (String.IsNullOrEmpty(toPath))   throw new ArgumentNullException("toPath");

    Uri fromUri = new Uri(fromPath);
    Uri toUri = new Uri(toPath);

    if (fromUri.Scheme != toUri.Scheme) { return toPath; } // path can't be made relative.

    Uri relativeUri = fromUri.MakeRelativeUri(toUri);
    String relativePath = Uri.UnescapeDataString(relativeUri.ToString());

    if (toUri.Scheme.Equals("file", StringComparison.InvariantCultureIgnoreCase))
    {
        relativePath = relativePath.Replace(Path.AltDirectorySeparatorChar, Path.DirectorySeparatorChar);
    }

    return relativePath;
}

Note that On Error Resume Next is not set globally. You can put your unsafe part of code eg into a function, which will interrupted immediately if error occurs, and call this function from sub containing precedent OERN statement.

ErrCatch()

Sub ErrCatch()
    Dim Res, CurrentStep

    On Error Resume Next

    Res = UnSafeCode(20, CurrentStep)
    MsgBox "ErrStep " & CurrentStep & vbCrLf & Err.Description

End Sub

Function UnSafeCode(Arg, ErrStep)

    ErrStep = 1
    UnSafeCode = 1 / (Arg - 10)

    ErrStep = 2
    UnSafeCode = 1 / (Arg - 20)

    ErrStep = 3
    UnSafeCode = 1 / (Arg - 30)

    ErrStep = 0
End Function

The uses of union Unions are used frequently when specialized type conversations are needed. To get an idea of the usefulness of union. The c/c standard library defines no function specifically designed to write short integers to a file. Using fwrite() incurs encurs excessive overhead for simple operation. However using a union you can easily create a function which writes binary of a short integer to a file one byte at a time. I assume that short integers are 2 byte long

THE EXAMPLE:

#include<stdio.h>
union pw {
short int i;
char ch[2];
};
int putw(short int num, FILE *fp);
int main (void)
{
FILE *fp;
fp fopen("test.tmp", "wb ");
putw(1000, fp); /* write the value 1000 as an integer*/
fclose(fp);
return 0;
}
int putw(short int num, FILE *fp)
{
pw word;
word.i = num;
putc(word.c[0] , fp);
return putc(word.c[1] , fp);
}    

although putw() i called with short integer, it was possble to use putc() and fwrite(). But i wanted to show an example to dominstrate how a union can be used

This question has been asked before. Please see this question.

Using the accepted answer and adapting it to your problem you get:

SELECT tt.*
FROM myTable tt
INNER JOIN
    (SELECT ID, MAX(Date) AS MaxDateTime
    FROM myTable
    GROUP BY ID) groupedtt 
ON tt.ID = groupedtt.ID 
AND tt.Date = groupedtt.MaxDateTime

Add environment only for __tests__ folder

You could add a .eslintrc.yml file in your __tests__ folders, that extends you basic configuration:

extends: <relative_path to .eslintrc>
env:
    jest: true

If you have only one __tests__folder, this solution is the best since it scope jest environment only where it is needed.

Dealing with many test folders

If you have more test folders (OPs case), I'd still suggest to add those files. And if you have tons of those folders can add them with a simple zsh script:

#!/usr/bin/env zsh

for folder in **/__tests__/ ;do
    count=$(($(tr -cd '/' <<< $folder | wc -c)))
    echo $folder : $count
    cat <<EOF > $folder.eslintrc.yml
extends: $(printf '../%.0s' {1..$count}).eslintrc
env:
    jest: true
EOF
done

This script will look for __tests__ folders and add a .eslintrc.yml file with to configuration shown above. This script has to be launched within the folder containing your parent .eslintrc.

If you are using Dot.Net then the code you need is

Environment.GetFolderPath(Environment.SpecialFolder.InternetCache)

Click my name if you want the code to delete these files plus FireFox temp files and Flash shared object/Flash Cookies

void operator could be used here.
Instead of:

React.useEffect(() => {
    async function fetchData() {
    }
    fetchData();
}, []);

or

React.useEffect(() => {
    (async function fetchData() {
    })()
}, []);

you could write:

React.useEffect(() => {
    void async function fetchData() {
    }();
}, []);

It is a little bit cleaner and prettier.

Async effects could cause memory leaks so it is important to perform cleanup on component unmount. In case of fetch this could look like this:

function App() {
    const [ data, setData ] = React.useState([]);

    React.useEffect(() => {
        const abortController = new AbortController();
        void async function fetchData() {
            try {
                const url = 'https://jsonplaceholder.typicode.com/todos/1';
                const response = await fetch(url, { signal: abortController.signal });
                setData(await response.json());
            } catch (error) {
                console.log('error', error);
            }
        }();
        return () => {
            abortController.abort(); // cancel pending fetch request on component unmount
        };
    }, []);

    return <pre>{JSON.stringify(data, null, 2)}</pre>;
}

Goto the Src folder of your Android project, and open the Java file.

Change the package OldName.android.widget to newName.android.widget.

It gives you an error like this

The declared package "newName.android.widget" does not match the expected package "OLDName.android.widget.

To fix this problem, select Move filename.Java to Newname.android.widget and delete the old package folder.

Next step: Go to AndroidManifest.xml and change package="OldName.android.widget" to package="newName.android.widget".

You can use generics with the following trick (casting to anonymous type):

public void LogEmployees<T>(IEnumerable<T> list)
{
    foreach (T item in list)
    {
        var typedItem = Cast(item, new { Name = "", Id = 0 });
        // now you can use typedItem.Name, etc.
    }
}

static T Cast<T>(object obj, T type)
{
    return (T)obj;
}

Test like this.Sometimes, permission problem.

cmd => dcomcnfg

Click

Component services >Computes >My Computer>Dcom config> and select micro soft Excel Application

Right Click on microsoft Excel Application

Properties>Give Asp.net Permissions

Select Identity table >Select interactive user >select ok

A better answer is that ++i will sometimes be faster but never slower.

Everyone seems to be assuming that i is a regular built-in type such as int. In this case there will be no measurable difference.

However if i is complex type then you may well find a measurable difference. For i++ you must make a copy of your class before incrementing it. Depending on what's involved in a copy it could indeed be slower since with ++it you can just return the final value.

Foo Foo::operator++()
{
  Foo oldFoo = *this; // copy existing value - could be slow
  // yadda yadda, do increment
  return oldFoo;
}

Another difference is that with ++i you have the option of returning a reference instead of a value. Again, depending on what's involved in making a copy of your object this could be slower.

A real-world example of where this can occur would be the use of iterators. Copying an iterator is unlikely to be a bottle-neck in your application, but it's still good practice to get into the habit of using ++i instead of i++ where the outcome is not affected.

The 500 code would normally indicate an error on the server, not anything with your code. Some thoughts

• Talk to the server developer for more info. You can't get more info directly.
• Verify your arguments into the call (values). Look for anything you might think could cause a problem for the server process. The process should not die and should return you a better code, but bugs happen there also.
• Could be intermittent, like if the server database goes down. May be worth trying at another time.

Try this,

HtmlElement head = _windowManager.ActiveBrowser.Document.GetElementsByTagName("head")[0];
HtmlElement scriptEl = _windowManager.ActiveBrowser.Document.CreateElement("script");
IHTMLScriptElement element = (IHTMLScriptElement)scriptEl.DomElement;
element.text = "window.onload = function() { document.forms[0].submit(); }";
head.AppendChild(scriptEl);
strAdditionalHeader = "";
_windowManager.ActiveBrowser.Document.InvokeScript("webBrowserControl");

If you need to configure a set of unique property=value lines, I recommend a more concise loop. For example:

- name: Configure kernel parameters
  lineinfile:
    dest: /etc/sysctl.conf
    regexp: "^{{ item.property | regex_escape() }}="
    line: "{{ item.property }}={{ item.value }}"
  with_items:
    - { property: 'kernel.shmall', value: '2097152' }
    - { property: 'kernel.shmmax', value: '134217728' }
    - { property: 'fs.file-max', value: '65536' }

Using a dict as suggested by Alix Axel and adding automatic removing of matching commented out entries,

- name: Configure IPV4 Forwarding
  lineinfile:
    path: /etc/sysctl.conf
    regexp: "^#? *{{ item.key | regex_escape() }}="
    line: "{{ item.key }}={{ item.value }}"
  with_dict:
    'net.ipv4.ip_forward': 1

our project surely is configured as "library" thats why you get the message : "Android library projects cannot be launched."

right-click in your project and select Properties. In the Properties window -> "Android" -> uncheck the option "is Library" and apply -> Click "ok" to close the properties window.

this stores the generated pdf file in your custom folder of your project

$filename= "{$membership->id}.pdf"; 
$filelocation = "D:\\wamp\\www\\project\\custom";//windows
$filelocation = "/var/www/project/custom"; //Linux

$fileNL = $filelocation."\\".$filename;//Windows
$fileNL = $filelocation."/".$filename; //Linux

$this->pdf->Output($fileNL, 'F');

H = "Hello"

if type(H) is list or type(H) is tuple:
    ## Do Something.
else
    ## Do Something.

To use Windows SDK successfully you need not only make include files available to your projects but also library files and executables (tools). To set all these directories you should use WinSDK Configuration Tool.

You can use sed for this too -

sed -n '320123'p filename 

This will print line number 320123.

If you want a range then you can do -

sed -n '320123,320150'p filename 

If you want from a particular line to the very end then -

sed -n '320123,$'p filename 

In case you haven't found the solution on the other answers, that's how I solved the issue.

Application.Current.Dispatcher.BeginInvoke(new Action(() =>
{
    TEXTBOX_OBJECT.Focus();
}), System.Windows.Threading.DispatcherPriority.Render);

From what I understand the other solutions may not work because the call to Focus() is invoked before the application has rendered the other components.

I've been able to get this to work by simply using [routerLink]="[]". The square brackets inside the quotes is important. No need to prevent default actions in the method or anything. This seems to be similar to the "!!" method but without needing to add that unclear syntax to the start of your method.

So your full anchor tag would look like this:

<a [routerLink]="[]" (click)="clickMethod()">Your Link</a>

Just make sure your method works correctly or else you might end up refreshing the page instead and it gets very confusing on what is actually wrong!

If you take a look at the source code of Spring Data JPA, and particularly the PartTreeJpaQuery class, you will see that is tries to instantiate PartTree. Inside that class the following regular expression

private static final Pattern PREFIX_TEMPLATE = Pattern.compile("^(find|read|get|count|query)(\\p{Lu}.*?)??By")

should indicate what is allowed and what's not.

Of course if you try to add such a method you will actually see that is does not work and you get the full stacktrace.

I should note that I was using looking at version 1.5.0.RELEASE of Spring Data JPA

1. Click on Window > Show view > Server or right click on the server in "Servers" view, select "Properties".
2. In the "General" panel, click on the "Switch Location" button.
3. The "Location: [workspace metadata]" should replace by something else.
4. Open the Overview screen for the server by double clicking it.
5. In the Server locations tab , select "Use Tomcat location".
6. Save the configurations and restart the Server.

You may want to follow the steps above before starting the server. Because server location section goes grayed-unreachable.

I need to add that, if the Module name and the sub name is the same you have such issue. Consider change the Module name to mod_Test instead of "Test" which is the same as the sub.

I just ran into this problem in Visual Studio 2013. Apparently now, having two projects in the same solution and setting the the dependencies is not enough. You need to add a project reference between them. To do that:

1. Right-click on the project in the solution explore
2. Click Add => References...
3. Click the Add New Reference button
4. Check the boxes for the projects that this project relies on
5. Click OK

SOAP uses WSDL for communication btw consumer and provider, whereas REST just uses XML or JSON to send and receive data

WSDL defines contract between client and service and is static by its nature. In case of REST contract is somewhat complicated and is defined by HTTP, URI, Media Formats and Application Specific Coordination Protocol. It's highly dynamic unlike WSDL.

SOAP doesn't return human readable result, whilst REST result is readable with is just plain XML or JSON

This is not true. Plain XML or JSON are not RESTful at all. None of them define any controls(i.e. links and link relations, method information, encoding information etc...) which is against REST as far as messages must be self contained and coordinate interaction between agent/client and service.

With links + semantic link relations clients should be able to determine what is next interaction step and follow these links and continue communication with service.

It is not necessary that messages be human readable, it's possible to use cryptic format and build perfectly valid REST applications. It doesn't matter whether message is human readable or not.

Thus, plain XML(application/xml) or JSON(application/json) are not sufficient formats for building REST applications. It's always reasonable to use subset of these generic media types which have strong semantic meaning and offer enough control information(links etc...) to coordinate interactions between client and server.

• For more details regarding control information I highly recommend to read this: http://www.amundsen.com/hypermedia/hfactor/
• Web Linking: http://tools.ietf.org/html/rfc5988
• Registered link relations: http://www.iana.org/assignments/link-relations/link-relations.xml

REST is over only HTTP

Not true, HTTP is most widely used and when we talk about REST web services we just assume HTTP. HTTP defines interface with it's methods(GET, POST, PUT, DELETE, PATCH etc) and various headers which can be used uniformly for interacting with resources. This uniformity can be achieved with other protocols as well.

P.S. Very simple, yet very interesting explanation of REST: http://www.looah.com/source/view/2284

You can use Timer

Timer timer = new Timer();

timer.schedule( new TimerTask() {
    public void run() {
       // do your work 
    }
 }, 0, 60*1000);

When the times comes

  timer.cancel();

To shut it down.

After struggling a bit with some of the answers here, I found a library called backoff that worked better for my situation. A basic example:

import backoff

@backoff.on_exception(
    backoff.expo,
    requests.exceptions.RequestException,
    max_tries=5,
    giveup=lambda e: e.response is not None and e.response.status_code < 500
)
def publish(self, data):
    r = requests.post(url, timeout=10, json=data)
    r.raise_for_status()

I'd still recommend giving the library's native functionality a shot, but if you run into any problems or need broader control, backoff is an option.

There is no way to do so, as JavaScript does not have an access to computer name, file system and other local info. Security is the main purpose.

RSS is the Resident Set Size and is used to show how much memory is allocated to that process and is in RAM. It does not include memory that is swapped out. It does include memory from shared libraries as long as the pages from those libraries are actually in memory. It does include all stack and heap memory.

VSZ is the Virtual Memory Size. It includes all memory that the process can access, including memory that is swapped out, memory that is allocated, but not used, and memory that is from shared libraries.

So if process A has a 500K binary and is linked to 2500K of shared libraries, has 200K of stack/heap allocations of which 100K is actually in memory (rest is swapped or unused), and it has only actually loaded 1000K of the shared libraries and 400K of its own binary then:

RSS: 400K + 1000K + 100K = 1500K
VSZ: 500K + 2500K + 200K = 3200K

Since part of the memory is shared, many processes may use it, so if you add up all of the RSS values you can easily end up with more space than your system has.

The memory that is allocated also may not be in RSS until it is actually used by the program. So if your program allocated a bunch of memory up front, then uses it over time, you could see RSS going up and VSZ staying the same.

There is also PSS (proportional set size). This is a newer measure which tracks the shared memory as a proportion used by the current process. So if there were two processes using the same shared library from before:

PSS: 400K + (1000K/2) + 100K = 400K + 500K + 100K = 1000K

Threads all share the same address space, so the RSS, VSZ and PSS for each thread is identical to all of the other threads in the process. Use ps or top to view this information in linux/unix.

There is way more to it than this, to learn more check the following references:

• http://manpages.ubuntu.com/manpages/en/man1/ps.1.html
• https://web.archive.org/web/20120520221529/http://emilics.com/blog/article/mconsumption.html

This is what I did to integrate Identity with an existing database.

1. Create a sample MVC project with MVC template. This has all the code needed for Identity implementation - Startup.Auth.cs, IdentityConfig.cs, Account Controller code, Manage Controller, Models and related views.

2. Install the necessary nuget packages for Identity and OWIN. You will get an idea by seeing the references in the sample Project and the answer by @Sam

3. Copy all these code to your existing project. Please note don't forget to add the "DefaultConnection" connection string for Identity to map to your database. Please check the ApplicationDBContext class in IdentityModel.cs where you will find the reference to "DefaultConnection" connection string.

4. This is the SQL script I ran on my existing database to create necessary tables:

If you don't want any dependency on Spring's HATEOAS or javax.* namespace, use ServletUriComponentsBuilder to get URI of current request:

import org.springframework.web.util.UriComponentsBuilder;

ServletUriComponentsBuilder.fromCurrentRequest();
ServletUriComponentsBuilder.fromCurrentRequestUri();

• perl -E: execute Perl with features supports (say, ...)
• say: print with a carrier return
• join ", ", ARRAY_HERE: join an array with ", "
• map {chomp; $_} ROWS: remove from each line the carrier return and return the result
• <>: stdin, each line is a ROW, coupling with a map it will create an array of each ROW

14. is prefix should be used for boolean variables and methods.

    isSet, isVisible, isFinished, isFound, isOpen

This is the naming convention for boolean methods and variables used by Sun for the Java core packages. Using the is prefix solves a common problem of choosing bad boolean names like status or flag. isStatus or isFlag simply doesn't fit, and the programmer is forced to chose more meaningful names.

Setter methods for boolean variables must have set prefix as in:

void setFound(boolean isFound);

There are a few alternatives to the is prefix that fits better in some situations. These are has, can and should prefixes:

boolean hasLicense(); 
boolean canEvaluate(); 
boolean shouldAbort = false;

You can get a list of the first element in each tuple using a list comprehension:

>>> my_tuples = [(1, 2, 3), ('a', 'b', 'c', 'd', 'e'), (True, False), 'qwerty']
>>> first_elts = [x[0] for x in my_tuples]
>>> first_elts
[1, 'a', True, 'q']

To me it happened in DogController that autowired DogService that autowired DogRepository. Dog class used to have field name but I changed it to coolName, but didn't change methods in DogRepository: Dog findDogByName(String name). I change that method to Dog findDogByCoolName(String name) and now it works.

CREATE PROCEDURE GetTaskEvents
@TaskName varchar(50),

Procedure Calling

DECLARE @return_value nvarchar(50)

SELECT  'Return Value' = @return_value

Here is my solution. Worked with script, which was ran by third party program with no WScript declared and no import allowed.

Function MySleep(milliseconds)
  set WScriptShell = CreateObject("WScript.Shell")
  WScriptShell.Run "Sleep -m " & milliseconds, 0, true
end Function

Update
Looks like Microsoft removed Sleep.exe from win 8, so this doesn't work in win 8 unless you put Sleep.exe in folder defined in %path%.

Maybe something like this:

SELECT count(*) FROM user_tab_columns WHERE table_name = 'FOO'

this will count number of columns in a the table FOO

You can also just

select count(*) from all_tab_columns where owner='BAR' and table_name='FOO';

where the owner is schema and note that Table Names are upper case

var a = [1,2,3,4,5,6,7,8,9];

var isSixInArray = a.filter(function(item){return item==6}).length ? true : false;

var isSixInArray = a.indexOf(6)>=0;

If you start tomcat from startup.bat, you need to add a system variable :JAVA_OPTS as name and the parameters that you wants (in your case :

-agentpath:C:\calltracer\jvmti\calltracer5.dll=traceFile-C:\calltracer\call.trace,filterFile-C:\calltracer\filters.txt,outputType-xml,usage-uncontrolled -Djava.library.path=C:\calltracer\jvmti -Dcalltracerlib=calltracer5

According to http://khason.net/blog/how-to-use-systemdrawingbitmap-hbitmap-in-wpf/

   [DllImport("gdi32")]
   static extern int DeleteObject(IntPtr o);

   public static BitmapSource loadBitmap(System.Drawing.Bitmap source)
   {
       IntPtr ip = source.GetHbitmap();
       BitmapSource bs = null;
       try
       {
           bs = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(ip, 
              IntPtr.Zero, Int32Rect.Empty, 
              System.Windows.Media.Imaging.BitmapSizeOptions.FromEmptyOptions());
       }
       finally
       {
           DeleteObject(ip);
       }

       return bs;
   }

It gets System.Drawing.Bitmap (from WindowsBased) and converts it into BitmapSource, which can be actually used as image source for your Image control in WPF.

image1.Source = YourUtilClass.loadBitmap(SomeBitmap);

There is one more way without creating a object also. Check the reference. Thanks for @cristian. Below I add the steps which mentioned in the above reference. For me I don't like to create a object for that and access. So I tried to access the getResources() without creating a object. I found this post. So I thought to add it as a answer.

Follow the steps to access getResources() in a non activity class without passing a context through the object.

• Create a subclass of Application, for instance public class App extends Application {. Refer the code next to the steps.
• Set the android:name attribute of your <application> tag in the AndroidManifest.xml to point to your new class, e.g. android:name=".App"
• In the onCreate() method of your app instance, save your context (e.g. this) to a static field named app and create a static method that returns this field, e.g. getContext().
• Now you can use: App.getContext() whenever you want to get a context, and then we can use App.getContext().getResources() to get values from the resources.

This is how it should look:

public class App extends Application{

    private static Context mContext;

    @Override
    public void onCreate() {
        super.onCreate();
        mContext = this;
    }

    public static Context getContext(){
        return mContext;
    }
}

You cannot do so - the browser will not allow this because of security concerns. Although there are workarounds, the fact is that you shouldn't count on this working. The following Stack Overflow questions are relevant here:

• full path from file input using jquery
• How to get the file path from HTML input form in Firefox 3

In addition to these, the new HTML5 specification states that browsers will need to feed a Windows compatible fakepath into the input type="file" field, ostensibly for backward compatibility reasons.

• http://lists.whatwg.org/htdig.cgi/whatwg-whatwg.org/2009-March/018981.html
• The Mystery of c:\fakepath Unveiled

So trying to obtain the path is worse then useless in newer browsers - you'll actually get a fake one instead.

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_below="@+id/activity_register_header"
    android:minHeight="50dp"
    android:orientation="vertical"
    android:visibility="gone" />

Try this piece of code..For me this code worked..

I thought you could deploy just your .aspx page without the .aspx.cs so long as the DLL was in your bin. Part of the issue here is how visual studio .net works with .aspx pages.

Check it out here: Working with Single-File Web Forms Pages in Visual Studio .NET

I know for sure that VS2008 with asp.net MVC RC you don't have code-behind files for your views.

Call c_str() to get a const char * (LPCSTR) from a std::string.

It's all in the name:

LPSTR - (long) pointer to string - char *

LPCSTR - (long) pointer to constant string - const char *

LPWSTR - (long) pointer to Unicode (wide) string - wchar_t *

LPCWSTR - (long) pointer to constant Unicode (wide) string - const wchar_t *

LPTSTR - (long) pointer to TCHAR (Unicode if UNICODE is defined, ANSI if not) string - TCHAR *

LPCTSTR - (long) pointer to constant TCHAR string - const TCHAR *

You can ignore the L (long) part of the names -- it's a holdover from 16-bit Windows.

UPDATE: This is no longer valid for newer Keras versions. Please use argmax() as in the answer from Emilia Apostolova.

The functional API models have just the predict() function which for classification would return the class probabilities. You can then select the most probable classes using the probas_to_classes() utility function. Example:

y_proba = model.predict(x)
y_classes = keras.np_utils.probas_to_classes(y_proba)

This is equivalent to model.predict_classes(x) on the Sequential model.

The reason for this is that the functional API support more general class of tasks where predict_classes() would not make sense.

More info: https://github.com/fchollet/keras/issues/2524

First of all, you should be using json.loads, not json.dumps. loads converts JSON source text to a Python value, while dumps goes the other way.

After you fix that, based on the JSON snippet at the top of your question, readable_json will be a list, and so readable_json['firstName'] is meaningless. The correct way to get the 'firstName' field of every element of a list is to eliminate the playerstuff = readable_json['firstName'] line and change for i in playerstuff: to for i in readable_json:.

In my case, the cause of the problem was multiple startup projects. I have three projects in my solution: Mvc, Api, and Dal. DbContext and Migrations in the Dal project.

I had configured multiple startup projects. Both Mvc and Api projects were running when I clicked Start. But in this case I was getting this error.

"Unable to create an object of type 'MyContext'. Add an implementation of 'IDesignTimeDbContextFactory' to the project, or see https://go.microsoft.com/fwlink/?linkid=851728 for additional patterns supported at design time."

I could successfully add migration after setting Mvc as the only startup project and selecting Dal in the Package Manager Console.

Looking for EventHandling, ActionListener?

or code?

JButton b = new JButton("Clear");
b.addActionListener(new ActionListener(){
    public void actionPerformed(ActionEvent e){
        textfield.setText("");
        //textfield.setText(null); //or use this
    }
});

I made my own version, based in the code presented above by @Tats_innit . The difference is the pause function. Works a little better in that aspect.

(function ($) {
var timeVar, width=0;

$.fn.textWidth = function () {
    var calc = '<span style="display:none">' + $(this).text() + '</span>';
    $('body').append(calc);
    var width = $('body').find('span:last').width();
    $('body').find('span:last').remove();
    return width;
};

$.fn.marquee = function (args) {
    var that = $(this);
    if (width == 0) { width = that.width(); };
    var textWidth = that.textWidth(), offset = that.width(), i = 0, stop = textWidth * -1, dfd = $.Deferred(),
        css = {
            'text-indent': that.css('text-indent'),
            'overflow': that.css('overflow'),
            'white-space': that.css('white-space')
        },
        marqueeCss = {
            'text-indent': width,
            'overflow': 'hidden',
            'white-space': 'nowrap'
        },
        args = $.extend(true, { count: -1, speed: 1e1, leftToRight: false, pause: false }, args);

    function go() {
        if (!that.length) return dfd.reject();
        if (width <= stop) {
            i++;
            if (i <= args.count) {
                that.css(css);
                return dfd.resolve();
            }
            if (args.leftToRight) {
                width = textWidth * -1;
            } else {
                width = offset;
            }
        }
        that.css('text-indent', width + 'px');
        if (args.leftToRight) {
            width++;
        } else {
            width=width-2;
        }
        if (args.pause == false) { timeVar = setTimeout(function () { go() }, args.speed); };
        if (args.pause == true) { clearTimeout(timeVar); };
    };

    if (args.leftToRight) {
        width = textWidth * -1;
        width++;
        stop = offset;
    } else {
        width--;
    }
    that.css(marqueeCss);

    timeVar = setTimeout(function () { go() }, 100);

    return dfd.promise();
};
})(jQuery);

usage:

for start: $('#Text1').marquee()

pause: $('#Text1').marquee({ pause: true })

resume: $('#Text1').marquee({ pause: false })

I always use this generic function to prevent errrors on primitive variables as well as arrays and objects.

isset = function(obj) {
  var i, max_i;
  if(obj === undefined) return false;
  for (i = 1, max_i = arguments.length; i < max_i; i++) {
    if (obj[arguments[i]] === undefined) {
        return false;
    }
    obj = obj[arguments[i]];
  }
  return true;
};

console.log(isset(obj));                   // returns false
var obj = 'huhu';
console.log(isset(obj));                   // returns true
obj = {hallo:{hoi:'hoi'}};
console.log(isset(obj, 'niet'));           // returns false
console.log(isset(obj, 'hallo'));          // returns true
console.log(isset(obj, 'hallo', 'hallo')); // returns false
console.log(isset(obj, 'hallo', 'hoi'));   // returns true

XmlSerializer sr = new XmlSerializer(objectToSerialize.GetType());
TextWriter xmlWriter = new StreamWriter(filename);
XmlSerializerNamespaces namespaces = new XmlSerializerNamespaces();
namespaces.Add(string.Empty, string.Empty);
sr.Serialize(xmlWriter, objectToSerialize, namespaces);

this inside of doThings is the window object. Try this instead:

var doThings = function (element) {
    var eventHandler = function(ev, func){
        if (element[ev] == undefined) {
            return;
        }

        element[ev] = function(e){
            func(e, element);
        }
    };

    return {
        eventHandler: eventHandler
    };
};

I guess the simple solution i found is below

ul{
    display:flex;
}

Be careful, that you do not use more than one constraint in the same direction and type.

For example: Vertical constraint for trailing = 15 and another one is >= 10.

Sometimes, Xcode creates some constraints you don't notice. You have to get rid of redundant constraints and the log warning will surely disappear.

Additionaly, you can read and detect some certain reasons, directly from the log:

NSLayoutConstraint:0xa338390 V:|-(15)-[UILabel:0xa331260] (Names: '|':UILabel:0xa330270 )>

This we can read as problem in UILabel constraint, it is leading vertical constraint being 15pt long.

NSLayoutConstraint:0x859ab20 H:-(13)-|[UIView:0x85a8fb0]...

This would be trailing horizontal constraint etc.

Solution for those who are interested in sending params and headers in GET request

$http.get('https://www.your-website.com/api/users.json', {
        params:  {page: 1, limit: 100, sort: 'name', direction: 'desc'},
        headers: {'Authorization': 'Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ=='}
    }
)
.then(function(response) {
    // Request completed successfully
}, function(x) {
    // Request error
});

Complete service example will look like this

var mainApp = angular.module("mainApp", []);

mainApp.service('UserService', function($http, $q){

   this.getUsers = function(page = 1, limit = 100, sort = 'id', direction = 'desc') {

        var dfrd = $q.defer();
        $http.get('https://www.your-website.com/api/users.json', 
            {
                params:{page: page, limit: limit, sort: sort, direction: direction},
                headers: {Authorization: 'Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ=='}
            }
        )
        .then(function(response) {
            if ( response.data.success == true ) { 

            } else {

            }
        }, function(x) {

            dfrd.reject(true);
        });
        return dfrd.promise;
   }

});

Open chrome

Right click => inspect => navigate to application tab

In Frames section, all the statically available assets(resources) such as css, JavaScript, fonts are listed.

Try the following :

try
{
    var fromEmailAddress =  ConfigurationManager.AppSettings["FromEmailAddress"].ToString();
    var fromEmailDisplayName = ConfigurationManager.AppSettings["FromEmailDisplayName"].ToString();
    var fromEmailPassword = ConfigurationManager.AppSettings["FromEmailPassword"].ToString();
    var smtpHost = ConfigurationManager.AppSettings["SMTPHost"].ToString();
    var smtpPort = ConfigurationManager.AppSettings["SMTPPort"].ToString();

    string body = "Your registration has been done successfully. Thank you.";
    MailMessage message = new MailMessage(new MailAddress(fromEmailAddress, fromEmailDisplayName), new MailAddress(ud.LoginId, ud.FullName));
    message.Subject = "Thank You For Your Registration";
    message.IsBodyHtml = true;
    message.Body = body;

    var client = new SmtpClient();
    client.Credentials = new NetworkCredential(fromEmailAddress, fromEmailPassword);
    client.Host = smtpHost;
    client.EnableSsl = true;
    client.Port = !string.IsNullOrEmpty(smtpPort) ? Convert.ToInt32(smtpPort) : 0;
    client.Send(message);
}
catch (Exception ex)
{
    throw (new Exception("Mail send failed to loginId " + ud.LoginId + ", though registration done."));
}

And then in you web.config add the following in between

<!--Email Config-->
<add key="FromEmailAddress" value="sender emailaddress"/>
<add key="FromEmailDisplayName" value="Display Name"/>
<add key="FromEmailPassword" value="sender Password"/>
<add key="SMTPHost" value="smtp-proxy.tm.net.my"/>
<add key="SMTPPort" value="smptp Port"/>

import operator
sorted_x = sorted(x, key=operator.attrgetter('score'))

if you want to sort x in-place, you can also:

x.sort(key=operator.attrgetter('score'))

A sample using C# is here.

public static void Main()
{
    Console.WriteLine("Hello World " + LevenshteinDistance("Hello","World"));
    Console.WriteLine("Choice A " + LevenshteinDistance("THE BROWN FOX JUMPED OVER THE RED COW","THE RED COW JUMPED OVER THE GREEN CHICKEN"));
    Console.WriteLine("Choice B " + LevenshteinDistance("THE BROWN FOX JUMPED OVER THE RED COW","THE RED COW JUMPED OVER THE RED COW"));
    Console.WriteLine("Choice C " + LevenshteinDistance("THE BROWN FOX JUMPED OVER THE RED COW","THE RED FOX JUMPED OVER THE BROWN COW"));
}

public static float LevenshteinDistance(string a, string b)
{
    var rowLen = a.Length;
    var colLen = b.Length;
    var maxLen = Math.Max(rowLen, colLen);

    // Step 1
    if (rowLen == 0 || colLen == 0)
    {
        return maxLen;
    }

    /// Create the two vectors
    var v0 = new int[rowLen + 1];
    var v1 = new int[rowLen + 1];

    /// Step 2
    /// Initialize the first vector
    for (var i = 1; i <= rowLen; i++)
    {
        v0[i] = i;
    }

    // Step 3
    /// For each column
    for (var j = 1; j <= colLen; j++)
    {
        /// Set the 0'th element to the column number
        v1[0] = j;

        // Step 4
        /// For each row
        for (var i = 1; i <= rowLen; i++)
        {
            // Step 5
            var cost = (a[i - 1] == b[j - 1]) ? 0 : 1;

            // Step 6
            /// Find minimum
            v1[i] = Math.Min(v0[i] + 1, Math.Min(v1[i - 1] + 1, v0[i - 1] + cost));
        }

        /// Swap the vectors
        var vTmp = v0;
        v0 = v1;
        v1 = vTmp;
    }

    // Step 7
    /// The vectors were swapped one last time at the end of the last loop,
    /// that is why the result is now in v0 rather than in v1
    return v0[rowLen];
}

The output is:

Hello World 4
Choice A 15
Choice B 6
Choice C 8

I tried this:

if(capital !== null){ 
//Capital has something 
}

  <p>This is the scenario: We have a container with an element inside of it that we want to center. I just added a little padding and background colors so both elements are distinquishable.</p>_x000D_

  <h2>Solution 2: Using <code>display: inline-block</code> and <code>text-align</code> (IE8)</h2>_x000D_
_x000D_
  <p>This method utilizes that <code>inline-block</code> elements are treated as text and as such they are affected by the <code>text-align</code> property. This does not rely on a fixed width which is an upside. This is helpful for when you don’t know the number of elements in a container for example.</p>_x000D_

  <h2>Solution 4: Using <code>translate()</code> and <code>position</code> (IE9)</h2>_x000D_
_x000D_
  <p>Don’t use as a general approach for horizontal centering elements. The downside here is that the centered element will be removed from the document flow. Notice the container shrinking to zero height with only the padding keeping it visible. This is what <i>removing an element from the document flow</i> means.</p>_x000D_
_x000D_
  <p>There are however applications for this technique. For example, it works for <b>vertically</b> centering by using <code>top</code> or <code>bottom</code> together with <code>translateY()</code>.</p>_x000D_

display: flex

.container {
  display: flex;
  justify-content: center;
}

Notes:

• It’s not a hack
• Browser support: flexbox

max-width & margin

You can horizontally center a block-level element by assigning a fixed width and setting margin-right and margin-left to auto.

.container ul {
  /* for IE below version 7 use `width` instead of `max-width` */
  max-width: 800px;
  margin-right: auto;
  margin-left: auto;
}

Notes:

• No container needed
• Requires (maximum) width of the centered element to be known

IE9+: transform: translatex(-50%) & left: 50%

This is similar to the quirky centering method which uses absolute positioning and negative margins.

.container {
  position: relative;
}

.container ul {
  position: absolute;
  left: 50%;
  transform: translatex(-50%);
}

Notes:

• The centered element will be removed from document flow. All elements will completely ignore of the centered element.
• This technique allows vertical centering by using top instead of left and translateY() instead of translateX(). The two can even be combined.
• Browser support: transform2d

IE8+: display: table & margin

Just like the first solution, you use auto values for right and left margins, but don’t assign a width. If you don’t need to support IE7 and below, this is better suited, although it feels kind of hacky to use the table property value for display.

.container ul {
  display: table;
  margin-right: auto;
  margin-left: auto;
}

IE8+: display: inline-block & text-align

Centering an element just like you would do with regular text is possible as well. Downside: You need to assign values to both a container and the element itself.

.container {
  text-align: center;
}

.container ul {
  display: inline-block;

  /* One most likely needs to realign flow content */
  text-align: initial;
}

Notes:

• Does not require to specify a (maximum) width
• Aligns flow content to the center (potentially unwanted side effect)
• Works kind of well with a dynamic number of menu items (i.e. in cases where you can’t know the width a single item will take up)

I suggest Oj as it is waaaaaay faster than the standard JSON library.

(see performance comparisons here)

None of this worked for me but I did figure this out.

Inside the storyboard I copied the corresponding ViewController into the clipboard and deleted it, afterwards I pasted it again.

Suddenly everything was working like a charm again!

Ok so if an image in a table is clicked you want the data of the first row of the table this image is in.

//image click stuff here {
$(this). // our image
closest('table'). // Go upwards through our parents untill we hit the table
children('tr:first'); // Select the first row we find

var $row = $(this).closest('table').children('tr:first');

parent() will only get the direct parent, closest should do what we want here. From jQuery docs: Get the first ancestor element that matches the selector, beginning at the current element and progressing up through the DOM tree.

GROUP BY 1

I've never known GROUP BY to support using ordinals, only ORDER BY. Either way, only MySQL supports GROUP BY's not including all columns without aggregate functions performed on them. Ordinals aren't recommended practice either because if they're based on the order of the SELECT - if that changes, so does your ORDER BY (or GROUP BY if supported).

There's no need to run GROUP BY on the contents when you're using UNION - UNION ensures that duplicates are removed; UNION ALL is faster because it doesn't - and in that case you would need the GROUP BY...

Your query only needs to be:

SELECT a.id,
       a.time
  FROM dbo.TABLE_A a
UNION
SELECT b.id,
       b.time
  FROM dbo.TABLE_B b

ok, this is a extract from the make function in hash.php

    $work = str_pad(8, 2, '0', STR_PAD_LEFT);

    // Bcrypt expects the salt to be 22 base64 encoded characters including
    // dots and slashes. We will get rid of the plus signs included in the
    // base64 data and replace them with dots.
    if (function_exists('openssl_random_pseudo_bytes'))
    {
        $salt = openssl_random_pseudo_bytes(16);
    }
    else
    {
        $salt = Str::random(40);
    }

    $salt = substr(strtr(base64_encode($salt), '+', '.'), 0 , 22);

    echo crypt('yourpassword', '$2a$'.$work.'$'.$salt);

Just copy/paste it into a php file and run it.
