For people who find this via search engines, you do not need VBA. You can just:

1.) select the query or table with your mouse
2.) click export data from the ribbon
3.) click excel from the export subgroup
4.) follow the wizard to select the output file and location.

I was getting this error and switched the queries to async (await (...).ToListAsync()). All good now.

I had the same problem. Changing controlers first letter to uppercase helped.

You can always use System.Resources.ResourceManager which returns the cached ResourceManager used by this class. Since chan1 and chan2 represent two different images, you may use System.Resources.ResourceManager.GetObject(string name) which returns an object matching your input with the project resources

Example

object O = Resources.ResourceManager.GetObject("chan1"); //Return an object from the image chan1.png in the project
channelPic.Image = (Image)O; //Set the Image property of channelPic to the returned object as Image

Notice: Resources.ResourceManager.GetObject(string name) may return null if the string specified was not found in the project resources.

Thanks,
I hope you find this helpful :)

For me the following command just worked:

aws s3 mv s3://bucket/data s3://bucket/old_data --recursive

Based on another Stack Overflow answer, Most lightweight way to create a random string and a random hexadecimal number, a better version than the accepted answer would be:

('%06x' % random.randrange(16**6)).upper()

much faster.

Figure sizes are specified in inches and can be included as a global option of the document output format. For example:

---
title: "My Document"
output:
  html_document:
    fig_width: 6
    fig_height: 4
---

And the plot's size in the graphic device can be increased at the chunk level:

```{r, fig.width=14, fig.height=12}          #Expand the plot width to 14 inches

ggplot(aes(x=mycolumn1, y=mycolumn2)) +     #specify the x and y aesthetic
geom_line(size=2) +                         #makes the line thicker
theme_grey(base_size = 25)                  #increases the size of the font
```

You can also use the out.width and out.height arguments to directly define the size of the plot in the output file:

```{r, out.width="200px", out.height="200px"} #Expand the plot width to 200 pixels

ggplot(aes(x=mycolumn1, y=mycolumn2)) +     #specify the x and y aesthetic
geom_line(size=2) +                         #makes the line thicker
theme_grey(base_size = 25)                  #increases the size of the font
```

Try ::after on previous element.

Elegant solution since Java 8:

File[] files = directory.listFiles();
Arrays.sort(files, Comparator.comparingLong(File::lastModified));

Or, if you want it in descending order, just reverse it:

File[] files = directory.listFiles();
Arrays.sort(files, Comparator.comparingLong(File::lastModified).reversed());

There is a library that can help with Unicode issues called ftfy. Has made my life easier.

Example 1

import ftfy
print(ftfy.fix_text('ünicode'))

output -->
ünicode

Example 2 - UTF-8

import ftfy
print(ftfy.fix_text('\xe2\x80\xa2'))

output -->
•

Example 3 - Unicode code point

import ftfy
print(ftfy.fix_text(u'\u2026'))

output -->
…

pip install ftfy

If the path in Ubuntu is "/home/ec2-user/Name of Directory", then do this:

1) Java's build.properties file:

build_path='/home/ec2-user/Name\\ of\\ Directory'

Where ~/ is equal to /home/ec2-user

2) Jenkinsfile:

build_path=buildprops['build_path']
echo "Build path= ${build_path}"
sh "cd ${build_path}"

This one just works by auto detecting the current user location.

import moment from "moment/min/moment-with-locales";

// Then use it as you always do. 
moment(yourDate).format("MMMM Do YYYY, h:mm a")

unsigned int count_bit(unsigned int x)
{
  x = (x & 0x55555555) + ((x >> 1) & 0x55555555);
  x = (x & 0x33333333) + ((x >> 2) & 0x33333333);
  x = (x & 0x0F0F0F0F) + ((x >> 4) & 0x0F0F0F0F);
  x = (x & 0x00FF00FF) + ((x >> 8) & 0x00FF00FF);
  x = (x & 0x0000FFFF) + ((x >> 16)& 0x0000FFFF);
  return x;
}

Let me explain this algorithm.

This algorithm is based on Divide and Conquer Algorithm. Suppose there is a 8bit integer 213(11010101 in binary), the algorithm works like this(each time merge two neighbor blocks):

+-------------------------------+
| 1 | 1 | 0 | 1 | 0 | 1 | 0 | 1 |  <- x
|  1 0  |  0 1  |  0 1  |  0 1  |  <- first time merge
|    0 0 1 1    |    0 0 1 0    |  <- second time merge
|        0 0 0 0 0 1 0 1        |  <- third time ( answer = 00000101 = 5)
+-------------------------------+

You can't do this using PHP.

As others have said, you could use cURL - but then the PHP code becomes the client rather than the browser.

If you must use POST, then the only way to do it would be to generate the populated form using PHP and use the window.onload hook to call javascript to submit the form.

Use Date.Now instead of DateTime.Now

I tried this and it worked:

Object obj = 10;
String str = obj.toString(); 
double d = Double.valueOf(str).doubleValue();

"cedivad" solved the issue for me with persistent result of Swedish chars ÅÄÖ.

$text = preg_replace( '/[^\p{L}\s]/u', '', $text );

Thanks!

You can't do it using environment variables directly. You need to use the set of "non standard" options that are passed to the java command. Run: java -X for details. The options you're looking for are -Xmx and -Xms (this is "initial" heap size, so probably what you're looking for.)

Some products like Ant or Tomcat might come with a batch script that looks for the JAVA_OPTS environment variable, but it's not part of the Java runtime. If you are using one of those products, you may be able to set the variable like:

set JAVA_OPTS="-Xms128m -Xmx256m"  

You can also take this approach with your own command line like:

set JAVA_OPTS="-Xms128m -Xmx256m"  
java ${JAVA_OPTS} MyClass

If you have pushed the commits upstream...

Select the commit you would like to roll back to and reverse the changes by clicking Reverse File, Reverse Hunk or Reverse Selected Lines. Do this for all the commits after the commit you would like to roll back to also.

If you have not pushed the commits upstream...

Right click on the commit and click on Reset current branch to this commit.

I know that this is a very old question, but I need it just now and I decided to implement my own solution, a pure python solution, that covers most uses cases (not all):

def load_properties(filepath, sep='=', comment_char='#'):
    """
    Read the file passed as parameter as a properties file.
    """
    props = {}
    with open(filepath, "rt") as f:
        for line in f:
            l = line.strip()
            if l and not l.startswith(comment_char):
                key_value = l.split(sep)
                key = key_value[0].strip()
                value = sep.join(key_value[1:]).strip().strip('"') 
                props[key] = value 
    return props

You can change the sep to ':' to parse files with format:

key : value

The code parses correctly lines like:

url = "http://my-host.com"
name = Paul = Pablo
# This comment line will be ignored

You'll get a dict with:

{"url": "http://my-host.com", "name": "Paul = Pablo" }

Environment.GetCommandLineArgs()[0]

I had same problem even after changing the password, it wasn't getting reflected in SQLDEVELOPER.

Atlast following solved my problem :

1. Open Command Propmt
2. Type sqlplus
3. login as sysdba
4. Run following command : alter user USERNAME identified by NEW_PASSWORD;

Think of the phrase in the square brackets as a WHERE clause in SQL.

So this query says, "select the "href" attribute (@) of an "a" tag that appears anywhere (//), but only where (the bracketed phrase) the textual contents of the "a" tag is equal to 'programming questions site'".

It's worth investigating the Pipeline plugin. With the plugin you can checkout multiple VCS projects into relative directory paths. Beforehand creating a directory per VCS checkout. Then issue commands to the newly checked out VCS workspace. In my case I am using git. But you should get the idea.

node{
    def exists = fileExists 'foo'
    if (!exists){
        new File('foo').mkdir()
    }
    dir ('foo') {
        git branch: "<ref spec>", changelog: false, poll: false, url: '<clone url>'
        ......
    }
    def exists = fileExists 'bar'
    if (!exists){
        new File('bar').mkdir()
    }
    dir ('bar') {
        git branch: "<ref spec>", changelog: false, poll: false, url: '<clone url>'
        ......
    }
    def exists = fileExists 'baz'
    if (!exists){
        new File('baz').mkdir()
    }
    dir ('baz') {
        git branch: "<ref spec>", changelog: false, poll: false, url: '<clone url>'
        ......
    }
}

It was changed between 3.1 and 3.2:

This is a terse description of the new features added to bash-3.2 since the release of bash-3.1.

Quoting the string argument to the [[ command's =~ operator now forces string matching, as with the other pattern-matching operators.

So use it without the quotes thus:

i="test"
if [[ $i =~ 200[78] ]] ; then
    echo "OK"
else
    echo "not OK"
fi

If you want to get rid of all leading and trailing extraneous whitespace then you want to do something like this:

// \\A = Start of input boundary
// \\z = End of input boundary 
string = string.replaceAll("\\A\\s+(.*?)\\s+\\z", "$1");

Then you can remove the duplicates using the other strategies listed here:

string = string.replaceAll("\\s+"," ");

According to jsPerf: Last item method, the most performant method is array[array.length-1]. The graph is displaying operations per second, not time per operation.

It is common (but wrong) for developers to think the performance of a single operation matters. It does not. Performance only matters when you're doing LOTS of the same operation. In that case, using a static value (length) to access a specific index (length-1) is fastest, and it's not even close.

"jdbc:mysql://localhost"

From the oracle docs..

jdbc:mysql://[host][,failoverhost...]
[:port]/[database]
[?propertyName1][=propertyValue1]
[&propertyName2][=propertyValue2]

host:port is the host name and port number of the computer hosting your database. If not specified, the default values of host and port are 127.0.0.1 and 3306, respectively.

database is the name of the database to connect to. If not specified, a connection is made with no default database.

failover is the name of a standby database (MySQL Connector/J supports failover).

propertyName=propertyValue represents an optional, ampersand-separated list of properties. These attributes enable you to instruct MySQL Connector/J to perform various tasks.

PuTTYgen for Ubuntu/Linux and PEM to PPK

sudo apt install putty-tools
puttygen -t rsa -b 2048 -C "user@host" -o keyfile.ppk

To get a list of all model classes, you can use ActiveRecord::Base.subclasses e.g.

ActiveRecord::Base.subclasses.map { |cl| cl.name }
ActiveRecord::Base.subclasses.find { |cl| cl.name == "Foo" }

@borislemke you can do this by similar way like

TextView  tv ;
findViewById(R.id.idOfTextView);
tv.setText(readNewTxt());
private String readNewTxt(){
InputStream inputStream = getResources().openRawResource(R.raw.yourNewTextFile);
 ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();

 int i;
 try {
 i = inputStream.read();
while (i != -1)
  {
   byteArrayOutputStream.write(i);
   i = inputStream.read();
   }
    inputStream.close();
  } catch (IOException e) {
   // TODO Auto-generated catch block
 e.printStackTrace();
 }

 return byteArrayOutputStream.toString();
 }

Hope below query will give the desired output:

Select id, home,datetime,player,resource, row_number() over (Partition by home ORDER by datetime desc) as rownum from tablename where rownum=1

Use a ContentProvider and load you data using a 'CursorLoader'. With this architecture your data will be automatically reloaded on database changes. Use third-party frameworks for your ContentProvider - you don't really want to implement it by yourself...

I created my own snippet that only adds {get; set;}. I made it just because I find prop → Tab to be clunky.

<?xml version="1.0" encoding="utf-8"?>
<CodeSnippets
    xmlns="http://schemas.microsoft.com/VisualStudio/2005/CodeSnippet">
    <CodeSnippet Format="1.0.0">
        <Header>
            <Title>get set</Title>
            <Shortcut>get</Shortcut>
        </Header>
        <Snippet>
            <Code Language="CSharp">
                <![CDATA[{get; set;}]]>
            </Code>
        </Snippet>
    </CodeSnippet>
</CodeSnippets>

With this, you type your PropType and PropName manually, then type get → Tab, and it will add the get set. It's nothing magical, but since I tend to type my access modifier first anyway, I may as well finish out the name and type.

The varStatus references to LoopTagStatus which has a getIndex() method.

So:

<c:forEach var="tableEntity" items='${requestScope.tables}' varStatus="outer">
   <c:forEach var="rowEntity" items='${tableEntity.rows}' varStatus="inner">            
        <c:out value="${(outer.index * fn:length(tableEntity.rows)) + inner.index}" />
    </c:forEach>
</c:forEach>

I have a shared hosting on GoDaddy. I needed an answer to this question, too, and after searching around I found that it is possible.

I wrote an .htaccess file, put it in the same folder as my action page. Here are the contents of the .htaccess file:

Header add Access-Control-Allow-Origin "*"
Header add Access-Control-Allow-Headers "origin, x-requested-with, content-type"
Header add Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS"

Here is my ajax call:

    $.ajax({
        url: 'http://www.mydomain.com/myactionpagefolder/gbactionpage.php',  //server script to process data
        type: 'POST',
        xhr: function() {  // custom xhr
            myXhr = $.ajaxSettings.xhr();
            if(myXhr.upload){ // check if upload property exists
                myXhr.upload.addEventListener('progress',progressHandlingFunction, false); // for handling the progress of the upload
            }
            return myXhr;
        },
        //Ajax events
        beforeSend: beforeSendHandler,
        success: completeHandler,
        error: errorHandler,
        // Form data
        data: formData,
        //Options to tell JQuery not to process data or worry about content-type
        cache: false,
        contentType: false,
        processData: false
    });

See this article for reference:

Header set Access-Control-Allow-Origin in .htaccess doesn't work

If you are fine with non-printable symbols in your json, then add ensure_ascii=False to dumps call.

>>> json.dumps(your_data, ensure_ascii=False)

If ensure_ascii is false, then the return value will be a unicode instance subject to normal Python str to unicode coercion rules instead of being escaped to an ASCII str.

Java doesn't pass objects, it passes references (pointers) to objects. So yes, l2 and l1 are two pointers to the same object.

You have to make an explicit copy if you need two different list with the same contents.

Yeah you can do some tricky works to simulate what you want:

1) Call your controller from a view by ajax. 2) Return your View

3) Use something like the following in the success (or maybe error! error works for me!) section of your $.ajax request:

$("#imgPrint").click(function () {
        $.ajax({
            url: ...,
            type: 'POST', dataType: 'json',
            data: $("#frm").serialize(),
            success: function (data, textStatus, jqXHR) {
                //Here it is:
                //Gets the model state
                var isValid = '@Html.Raw(Json.Encode(ViewData.ModelState.IsValid))'; 
                // checks that model is valid                    
                if (isValid == 'true') {
                    //open new tab or window - according to configs of browser
                    var w = window.open();
                    //put what controller gave in the new tab or win 
                    $(w.document.body).html(jqXHR.responseText);
                }
                $("#imgSpinner1").hide();
            },
            error: function (jqXHR, textStatus, errorThrown) {
                // And here it is for error section. 
                //Pay attention to different order of 
                //parameters of success and error sections!
                var isValid = '@Html.Raw(Json.Encode(ViewData.ModelState.IsValid))';                    
                if (isValid == 'true') {
                    var w = window.open();
                    $(w.document.body).html(jqXHR.responseText);
                }
                $("#imgSpinner1").hide();
            },
            beforeSend: function () { $("#imgSpinner1").show(); },
            complete: function () { $("#imgSpinner1").hide(); }
        });            
    });      

If a string must not contain @, every character must be another character than @:

/^[^@]*$/

This will match any string of any length that does not contain @.

Another possible solution would be to invert the boolean result of /@/.

This works for me and you don't need the inline script:

Javascript:

    $(document).ready(function() {
    $('.showme').bind('click', function() {

        var id=$(this).attr("id");
        var num=$(this).attr("class");
        var poststr="request="+num+"&moreinfo="+id;
        $.ajax({
              url:"testme.php",
              cache:0,
              data:poststr,
              success:function(result){
                     document.getElementById("stuff").innerHTML=result;
               }
        }); 
    });
 });

HTML:

    <div class='request_1 showme' id='rating_1'>More stuff 1</div>
    <div class='request_2 showme' id='rating_2'>More stuff 2</div>
    <div class='request_3 showme' id='rating_3'>More stuff 3</div>

    <div id="stuff">Here is some stuff that will update when the links above are clicked</div>

The request is sent to testme.php:

    header("Cache-Control: no-cache");
    header("Pragma: nocache");

    $request_id = preg_replace("/[^0-9]/","",$_REQUEST['request']);
    $request_moreinfo = preg_replace("/[^0-9]/","",$_REQUEST['moreinfo']);

    if($request_id=="1")
    {
        echo "show 1";
    }
    elseif($request_id=="2")
    {
        echo "show 2";
    }
    else
    {
        echo "show 3";
    }

I have also worked on this clausing and extraction operations for my assignment.

Try this ...

Dim r as Range
Dim x as Integer

For x = 5000 to 4 step -1 '---> or change as you want //Thanx 4 KazJaw

  set r = range("E" & format(x))
  if ucase(r.Value) = "NONE" then

JSON.stringify takes more optional arguments.

Try:

 JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, 4); // Indented 4 spaces
 JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, "\t"); // Indented with tab

How can I beautify JSON programmatically?

Should work in modern browsers, and it is included in json2.js if you need a fallback for browsers that don't support the JSON helper functions. For display purposes, put the output in a <pre> tag to get newlines to show.

One of the Related posts gave me the (simple) answer.

Apparently the auto value on the grid-template-rows property does exactly what I was looking for.

.grid {
    display:grid;
    grid-template-columns: 1fr 1.5fr 1fr;
    grid-template-rows: auto auto 1fr 1fr 1fr auto auto;
    grid-gap:10px;
    height: calc(100vh - 10px);
}

I was getting this error while trying to show DatePicker from Fragment.

I changed

val datePickerDialog = DatePickerDialog(activity!!.applicationContext, ...)

to

val datePickerDialog = DatePickerDialog(requireContext(), ...)

and it worked just fine.

I have face this issue in post request. I have changed like this in axios header. It works fine.

axios.post('http://localhost/M-Experience/resources/GETrends.php',
      {
        firstName: this.name
      },
      {
        headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
      });

Here is an example implementation, which would make this process seamless (Borrowed from AngularJs)

var CookieReader = (function(){
var lastCookies = {};
var lastCookieString = '';

function safeGetCookie() {
    try {
        return document.cookie || '';
    } catch (e) {
        return '';
    }
}

function safeDecodeURIComponent(str) {
    try {
        return decodeURIComponent(str);
    } catch (e) {
        return str;
    }
}

function isUndefined(value) {
    return typeof value === 'undefined';
}

return function () {
    var cookieArray, cookie, i, index, name;
    var currentCookieString = safeGetCookie();

    if (currentCookieString !== lastCookieString) {
        lastCookieString = currentCookieString;
        cookieArray = lastCookieString.split('; ');
        lastCookies = {};

        for (i = 0; i < cookieArray.length; i++) {
            cookie = cookieArray[i];
            index = cookie.indexOf('=');
            if (index > 0) { //ignore nameless cookies
                name = safeDecodeURIComponent(cookie.substring(0, index));

                if (isUndefined(lastCookies[name])) {
                    lastCookies[name] = safeDecodeURIComponent(cookie.substring(index + 1));
                }
            }
        }
    }
    return lastCookies;
};
})();

You can use Open Xml Sdk for this. If you have the code in html with color and formatting. You can use altchunks to add it to the word documents. Refer this post Add HTML String to OpenXML (*.docx) Document Hope this helps!

This prototype getUnique is not totally correct, because if i have a Array like: ["1",1,2,3,4,1,"foo"] it will return ["1","2","3","4"] and "1" is string and 1 is a integer; they are different.

Here is a correct solution:

Array.prototype.unique = function(a){
    return function(){ return this.filter(a) }
}(function(a,b,c){ return c.indexOf(a,b+1) < 0 });

using:

var foo;
foo = ["1",1,2,3,4,1,"foo"];
foo.unique();

The above will produce ["1",2,3,4,1,"foo"].

There is also some more detail on the use of <mvc:annotation-driven /> in the Spring docs. In a nutshell, <mvc:annotation-driven /> gives you greater control over the inner workings of Spring MVC. You don't need to use it unless you need one or more of the features outlined in the aforementioned section of the docs.

Also, there are other "annotation-driven" tags available to provide additional functionality in other Spring modules. For example, <transaction:annotation-driven /> enables the use of the @Transaction annotation, <task:annotation-driven /> is required for @Scheduled et al...

First represent the epoch of the millisecond time as a date (usually 1/1/1970), then add your millisecond time divided by the number of milliseconds in a day (86400000):

=DATE(1970,1,1)+(A1/86400000)

If your cell is properly formatted, you should see a human-readable date/time.

jQuery now defines a when function for this purpose.

It accepts any number of Deferred objects as arguments, and executes a function when all of them resolve.

That means, if you want to initiate (for example) four ajax requests, then perform an action when they are done, you could do something like this:

$.when(ajax1(), ajax2(), ajax3(), ajax4()).done(function(a1, a2, a3, a4){
    // the code here will be executed when all four ajax requests resolve.
    // a1, a2, a3 and a4 are lists of length 3 containing the response text,
    // status, and jqXHR object for each of the four ajax calls respectively.
});

function ajax1() {
    // NOTE:  This function must return the value 
    //        from calling the $.ajax() method.
    return $.ajax({
        url: "someUrl",
        dataType: "json",
        data:  yourJsonData,            
        ...
    });
}

In my opinion, it makes for a clean and clear syntax, and avoids involving any global variables such as ajaxStart and ajaxStop, which could have unwanted side effects as your page develops.

If you don't know in advance how many ajax arguments you need to wait for (i.e. you want to use a variable number of arguments), it can still be done but is just a little bit trickier. See Pass in an array of Deferreds to $.when() (and maybe jQuery .when troubleshooting with variable number of arguments).

If you need deeper control over the failure modes of the ajax scripts etc., you can save the object returned by .when() - it's a jQuery Promise object encompassing all of the original ajax queries. You can call .then() or .fail() on it to add detailed success/failure handlers.

The Y array in your screenshot is not a 1D array, it's a 2D array with 300 rows and 1 column, as indicated by its shape being (300, 1).

To remove the extra dimension, you can slice the array as Y[:, 0]. To generally convert an n-dimensional array to 1D, you can use np.reshape(a, a.size).

Another option for converting a 2D array into 1D is flatten() function from numpy.ndarray module, with the difference that it makes a copy of the array.

For the log folder and file stuff, go with @Bens answer.

I will comment on the creating log part, though. Imo there is no correct way. When coding loggers manually I do it the way you're doing it:

ILog logger = LogManager.GetLogger(typeof(CCController));

because it is short and concise.

That said, I do not create the logger instances inside the classes these days, I let my IoC container inject it for me.

Like this:

{% if age > 18 %}
    {% with patient as p %}
    <my html here>
    {% endwith %}
{% else %}
    {% with patient.parent as p %}
    <my html here>
    {% endwith %}
{% endif %}

If the html is too big and you don't want to repeat it, then the logic would better be placed in the view. You set this variable and pass it to the template's context:

p = (age > 18 && patient) or patient.parent

and then just use {{ p }} in the template.

i like little safety and i use this

   Array.prototype.Insert = function (item, before) {
        if (!item) return;
        if (before == null || before < 0 || before > this.length - 1) {
            this.push(item);
            return;
        }
        this.splice(before, 0,item );
    }
    
    
   var t = ["a","b"]
   
   t.Insert("v",1)
    
    console.log(t )

latest is really designed to work with date fields (it probably does work with other total-ordered types too, but not sure). And the only way you can use it without specifying the field name is by setting the get_latest_by meta attribute, as mentioned here.

Try GPU++ and libSh

LibSh link has a good description of how they bound the programming language to the graphics primitives (and obviously, the primitives themselves), and GPU++ describes what its all about, both with code examples.

I think the semantics being used in your class are confusing. What's probably meant by 'static' is simply "constant size", and what's probably meant by "dynamic" is "variable size". In that case then, a constant size array might look like this:

int x[10];

and a "dynamic" one would just be any kind of structure that allows for the underlying storage to be increased or decreased at runtime. Most of the time, the std::vector class from the C++ standard library will suffice. Use it like this:

std::vector<int> x(10); // this starts with 10 elements, but the vector can be resized.

std::vector has operator[] defined, so you can use it with the same semantics as an array.

An IEnumerator is a thing that can enumerate: it has the Current property and the MoveNext and Reset methods (which in .NET code you probably won't call explicitly, though you could).

An IEnumerable is a thing that can be enumerated...which simply means that it has a GetEnumerator method that returns an IEnumerator.

Which do you use? The only reason to use IEnumerator is if you have something that has a nonstandard way of enumerating (that is, of returning its various elements one-by-one), and you need to define how that works. You'd create a new class implementing IEnumerator. But you'd still need to return that IEnumerator in an IEnumerable class.

For a look at what an enumerator (implementing IEnumerator<T>) looks like, see any Enumerator<T> class, such as the ones contained in List<T>, Queue<T>, or Stack<T>. For a look at a class implementing IEnumerable, see any standard collection class.

However there are very good answers already available for this. Here is my answer:

1. set.stream().forEach(System.out::println); // It simply uses stream to display set values
2. set.forEach(System.out::println); // It uses Enhanced forEach to display set values

Also, if this Set is of Custom class type, for eg: Customer.

Set<Customer> setCust = new HashSet<>();
    Customer c1 = new Customer(1, "Hena", 20);
    Customer c2 = new Customer(2, "Meena", 24);
    Customer c3 = new Customer(3, "Rahul", 30);

setCust.add(c1);
setCust.add(c2);
setCust.add(c3);
    setCust.forEach((k) -> System.out.println(k.getId()+" "+k.getName()+" "+k.getAge()));

// Customer class:

class Customer{
private int id;
private String name;
private int age;

public Customer(int id,String name,int age){
this.id=id;
this.name=name;
this.age=age;
} // Getter, Setter methods are present.}

Use this:

replace series of newlines with an empty string:

$string = preg_replace("/[\\n\\r]+/", "", $string);

or you probably want to replace newlines with a single space:

$string = preg_replace("/[\\n\\r]+/", " ", $string);

To change image onclik with javascript you need to have image with id:

<p>
        <img alt="" src="http://www.userinterfaceicons.com/80x80/minimize.png" 
            style="height: 85px; width: 198px" id="imgClickAndChange" onclick="changeImage()"  />
</p>

Then you could call javascript function when image is clicked:

<script language="javascript">
    function changeImage() {

        if (document.getElementById("imgClickAndChange").src == "http://www.userinterfaceicons.com/80x80/minimize.png") 
        {
            document.getElementById("imgClickAndChange").src = "http://www.userinterfaceicons.com/80x80/maximize.png";
        }
        else 
        {
            document.getElementById("imgClickAndChange").src = "http://www.userinterfaceicons.com/80x80/minimize.png";
        }
    }
</script>

This code will set image to maximize.png if current img.src is set to minimize.png and vice versa. For more details visit: Change image onclick with javascript link

This other approach works well for me:

$("#myModal").on("show.bs.modal", function(e) {
    var link = $(e.relatedTarget);
    $(this).find(".modal-body").load(link.attr("href"));
});

If by the type of a variable you mean the runtime class of the object that the variable points to, then you can get this through the class reference that all objects have.

val name = "sam";
name: java.lang.String = sam
name.getClass
res0: java.lang.Class[_] = class java.lang.String

If you however mean the type that the variable was declared as, then you cannot get that. Eg, if you say

val name: Object = "sam"

then you will still get a String back from the above code.

There is a good explanation of why it is costly to use + for concatenating a large number of strings here

Plus operator is perfectly fine solution to concatenate two Python strings. But if you keep adding more than two strings (n > 25) , you might want to think something else.

''.join([a, b, c]) trick is a performance optimization.

In Codeigniter This is simple Way to check between two date records ...

$start_date='2016-01-01';
$end_date='2016-01-31';

$this->db->where('date BETWEEN "'. date('Y-m-d', strtotime($start_date)). '" and "'. date('Y-m-d', strtotime($end_date)).'"');

Static members need to be initialized in a .cpp translation unit at file scope or in the appropriate namespace:

const string foo::s( "my foo");

Use the Take(int n) method:

var q = query.Take(10);

You are looking for continue.

There's racing car simulator game TORCS also where on top of the typical end user playing it (you actually "driving" the cars), you can program robots which control the cars. Regular races are held between robots created by different people.

It is not listed as a function in dplyr (yet): http://cran.rstudio.org/web/packages/dplyr/dplyr.pdf

The function below works (almost) the same if you don't want to load both plyr and dplyr

rename <- function(dat, oldnames, newnames) {
  datnames <- colnames(dat)
  datnames[which(datnames %in% oldnames)] <- newnames
  colnames(dat) <- datnames
  dat
}

dat <- rename(mtcars,c("mpg","cyl"), c("mympg","mycyl"))
head(dat)

The way I recommend with JPA 2 :

Object unproxied  = entityManager.unwrap(SessionImplementor.class).getPersistenceContext().unproxy(proxy);

I think String.prototype.reverse is a good way to solve this problem; the code as below;

String.prototype.reverse = function() {
  return this.split('').reverse().join('');
}

var str = 'this is a good example for string reverse';
str.reverse();

Not exactly true -- take a look at the specs summary

Logical link control and adaptation protocol (L2CAP)

L2CAP is used within the Bluetooth protocol stack. It passes packets to either the Host Controller Interface (HCI) or on a hostless system, directly to the Link Manager/ACL link. L2CAP's functions include:

• Multiplexing data between different higher layer protocols.
• Segmentation and reassembly of packets.
• Providing one-way transmission management of multicast data to a group of other Bluetooth devices.
• Quality of service (QoS) management for higher layer protocols.

L2CAP is used to communicate over the host ACL link. Its connection is established after the ACL link has been set up.

"Concurrency" is when there are multiple things in progress.

"Parallelism" is when concurrent things are progressing at the same time.

Examples of concurrency without parallelism:

• Multiple threads on a single core.
• Multiple messages in a Win32 message queue.
• Multiple SqlDataReaders on a MARS connection.
• Multiple JavaScript promises in a browser tab.

Note, however, that the difference between concurrency and parallelism is often a matter of perspective. The above examples are non-parallel from the perspective of (observable effects of) executing your code. But there is instruction-level parallelism even within a single core. There are pieces of hardware doing things in parallel with CPU and then interrupting the CPU when done. GPU could be drawing to screen while you window procedure or event handler is being executed. The DBMS could be traversing B-Trees for the next query while you are still fetching the results of the previous one. Browser could be doing layout or networking while your Promise.resolve() is being executed. Etc, etc...

So there you go. The world is as messy as always ;)

Value validation wouldn't be a responsibility of jQuery. You can use pure JavaScript for this. Two ways that come to my mind are:

/^\d+$/.match(value)
Number(value) == value

So you could do something like this

Function Errorthingy(pParam)
On Error GoTo HandleErr

 ' your code here

    ExitHere:
    ' your finally code
    Exit Function

    HandleErr:
        Select Case Err.Number
        ' different error handling here'
        Case Else
            MsgBox "Error " & Err.Number & ": " & Err.Description, vbCritical, "ErrorThingy"
        End Select


   Resume ExitHere

End Function

If you want to bake in custom exceptions. (e.g. ones that violate business rules) use the example above but use the goto to alter the flow of the method as necessary.

Following on from Benjamin Muschko's answer (19 March 2011), you can use the -i flag along with grep, to filter out 1000s of unwanted lines. Examples:

Strong filter - Only display each unit test name and test result and the overall build status. Setup errors or exceptions are not displayed.

./gradlew test -i | grep -E " > |BUILD"

Soft filter - Display each unit test name and test result, as well as setup errors/exceptions. But it will also include some irrelevant info:

./gradlew test -i | grep -E -v "^Executing |^Creating |^Parsing |^Using |^Merging |^Download |^title=Compiling|^AAPT|^future=|^task=|:app:|V/InstrumentationResultParser:"

Soft filter, Alternative syntax: (search tokens are split into individual strings)

./gradlew test -i | grep -v -e "^Executing " -e "^Creating " -e "^Parsing " -e "^Using " -e "^Merging " -e "^Download " -e "^title=Compiling" -e "^AAPT" -e "^future=" -e "^task=" -e ":app:" -e "V/InstrumentationResultParser:"

Explanation of how it works:

The first command is ./gradlew test -i and "-i" means "Info/Verbose" mode, which prints the result of each test in real-time, but also displays large amounts of unwanted debug lines.

So the output of the first command, ./gradlew test -i, is piped to a second command grep, which will filter out many unwanted lines, based on a regular expression. "-E" enables the regular expression mode for a single string; "-e" enables regular expressions for multiple strings; and "|" in the regex string means "or".

In the strong filter, a unit test name and test result is allowed to display using " > ", and the overall status is allowed with "BUILD".

In the soft filter, the "-v" flag means "not containing" and "^" means "start of line". So it strips out all lines that start with "Executing " or start with "Creating ", etc.

Example for Android instrumentation unit tests, with gradle 5.1:

./gradlew connectedDebugAndroidTest --continue -i | grep -v -e \
    "^Transforming " -e "^Skipping " -e "^Cache " -e "^Performance " -e "^Creating " -e \
    "^Parsing " -e "^file " -e "ddms: " -e ":app:" -e "V/InstrumentationResultParser:"

Example for Jacoco unit test coverage, with gradle 4.10:

./gradlew createDebugCoverageReport --continue -i | grep -E -v "^Executing |^Creating |^Parsing |^Using |^Merging |^Download |^title=Compiling|^AAPT|^future=|^task=|:app:|V/InstrumentationResultParser:"

Have you tried to cast it to a date, with <mydatetime>::date ?

function initialize() {
    var location = new google.maps.LatLng(44.5403, -78.5463);
    var mapCanvas = document.getElementById('map_canvas');
    var map_options = {
      center: location,
      zoom: 15,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    }
    var map = new google.maps.Map(map_canvas, map_options);

    new google.maps.Marker({
        position: location,
        map: map

}
google.maps.event.addDomListener(window, 'load', initialize);

Easiest way

The most trivial way to download a binary file from an FTP server using .NET framework is using WebClient.DownloadFile:

WebClient client = new WebClient();
client.Credentials = new NetworkCredential("username", "password");
client.DownloadFile(
    "ftp://ftp.example.com/remote/path/file.zip", @"C:\local\path\file.zip");

Advanced options

Use FtpWebRequest, only if you need a greater control, that WebClient does not offer (like TLS/SSL encryption, progress monitoring, ascii/text transfer mode, resuming transfers, etc). Easy way is to just copy an FTP response stream to FileStream using Stream.CopyTo:

FtpWebRequest request =
    (FtpWebRequest)WebRequest.Create("ftp://ftp.example.com/remote/path/file.zip");
request.Credentials = new NetworkCredential("username", "password");
request.Method = WebRequestMethods.Ftp.DownloadFile;

using (Stream ftpStream = request.GetResponse().GetResponseStream())
using (Stream fileStream = File.Create(@"C:\local\path\file.zip"))
{
    ftpStream.CopyTo(fileStream);
}

Progress monitoring

If you need to monitor a download progress, you have to copy the contents by chunks yourself:

FtpWebRequest request =
    (FtpWebRequest)WebRequest.Create("ftp://ftp.example.com/remote/path/file.zip");
request.Credentials = new NetworkCredential("username", "password");
request.Method = WebRequestMethods.Ftp.DownloadFile;

using (Stream ftpStream = request.GetResponse().GetResponseStream())
using (Stream fileStream = File.Create(@"C:\local\path\file.zip"))
{
    byte[] buffer = new byte[10240];
    int read;
    while ((read = ftpStream.Read(buffer, 0, buffer.Length)) > 0)
    {
        fileStream.Write(buffer, 0, read);
        Console.WriteLine("Downloaded {0} bytes", fileStream.Position);
    }
}

For GUI progress (WinForms ProgressBar), see:
FtpWebRequest FTP download with ProgressBar

Downloading folder

If you want to download all files from a remote folder, see
C# Download all files and subdirectories through FTP.

Leaving this here for myself,

If I get this error, I probably used const char* when I should be using char* const.

This makes the pointer constant, and not the contents of the string.

const char* const makes it so the value and the pointer is constant also.

change the div to display block

You can use Task Scheduler Managed Wrapper:

using System;
using Microsoft.Win32.TaskScheduler;

class Program
{
   static void Main(string[] args)
   {
      // Get the service on the local machine
      using (TaskService ts = new TaskService())
      {
         // Create a new task definition and assign properties
         TaskDefinition td = ts.NewTask();
         td.RegistrationInfo.Description = "Does something";

         // Create a trigger that will fire the task at this time every other day
         td.Triggers.Add(new DailyTrigger { DaysInterval = 2 });

         // Create an action that will launch Notepad whenever the trigger fires
         td.Actions.Add(new ExecAction("notepad.exe", "c:\\test.log", null));

         // Register the task in the root folder
         ts.RootFolder.RegisterTaskDefinition(@"Test", td);

         // Remove the task we just created
         ts.RootFolder.DeleteTask("Test");
      }
   }
}

Alternatively you can use native API or go for Quartz.NET. See this for details.

List<int> list = new List<int> { 1, 3, 5 };
list.ForEach(x => Console.WriteLine(x));

Edit: Dammit! took too long to open visual studio to test it.

mvn install is the option that is most often used.
mvn package is seldom used, only if you're debugging some issue with the maven build process.

See: http://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.html

Note that mvn package will only create a jar file.
mvn install will do that and install the jar (and class etc.) files in the proper places if other code depends on those jars.

I usually do a mvn clean install; this deletes the target directory and recreates all jars in that location.
The clean helps with unneeded or removed stuff that can sometimes get in the way.
Rather then debug (some of the time) just start fresh all of the time.

Not tested, but I think you can do the following:

dataGrid.Rows[index].Selected = true;

or you could do the following (but again: not tested):

dataGrid.SelectedRows.Clear();
foreach(DataGridViewRow row in dataGrid.Rows)
{
    if(YOUR CONDITION)
       row.Selected = true;
}

Or you could figure out the exacting amount of hours and minutes and have that displayed by puttin it into the timer app that already exist in every iphone :)

Perl one-liner similar to @jonas's awk solution:

perl -ne 'print if ! $x{$_}++' file

This variation removes trailing whitespace before comparing:

perl -lne 's/\s*$//; print if ! $x{$_}++' file

This variation edits the file in-place:

perl -i -ne 'print if ! $x{$_}++' file

This variation edits the file in-place, and makes a backup file.bak

perl -i.bak -ne 'print if ! $x{$_}++' file

You can't take a screen-shot: it would be an irresponsible security risk to let you do so. However, you can:

• Do things server-side and generate an image
• Draw something similar to a Canvas and render that to an image (in a browser that supports it)
• Use some other drawing library to draw directly to the image (slow, but would work on any browser)

I get the same error in Chrome after pasting code copied from jsfiddle.

If you select all the code from a panel in jsfiddle and paste it into the free text editor Notepad++, you should be able to see the problem character as a question mark "?" at the very end of your code. Delete this question mark, then copy and paste the code from Notepad++ and the problem will be gone.

Have you added the google maven endpoint?

Important: The support libraries are now available through Google's Maven repository. You do not need to download the support repository from the SDK Manager. For more information, see Support Library Setup.

Add the endpoint to your build.gradle file:

allprojects {
    repositories {
        jcenter()
        maven {
            url 'https://maven.google.com'
        }
    }
}

Which can be replaced by the shortcut google() since Android Gradle v3:

allprojects {
    repositories {
        jcenter()
        google()
    }
}

If you already have any maven url inside repositories, you can add the reference after them, i.e.:

allprojects {
    repositories {
        jcenter()
        maven {
            url 'https://jitpack.io'
        }
        maven {
            url 'https://maven.google.com'
        }
    }
}

Following is a more simple way:

<table>
    <tr ng-repeat="item in lists" ng-hide="$index%2!==0">
        <td>
            <label>{{ lists[$index].name}}</label>
        </td>
        <td ng-hide="!lists[$index+1]">
            <label>{{ lists[$index+1].name}}</label>
        </td>
    </tr>
</table>

Cumulo Nimbus's answer is useful for me but I want this grid wrapped by a div which can show the scrollbar when the list is too long.

To achieve this I added style="height:200px; overflow:auto" to a div around the table which causes it to show as a single column.

Now works for array length of one.

<p><b> BOLD TEXT </b> not in bold </p>;

Include the text you want to be in bold between <b>...</b>

So basically as mentioned by Cherniv we need to bootstrap the modules to have multiple ng-app within the same page. Many thanks for all the inputs.

Please try this way.... I have tested this code.... It works....

$memcachedConfig = array("host" => "127.0.0.1","port" => "11211");
print_r($memcachedConfig['host']);

Had this problem and solved typing this : C:\Program Files (x86)\Java\jdk1.7.0_51\bin\javadoc.exe

The (^) XOR operator generates 1 when it is applied on two different bits (0 and 1). It generates 0 when it is applied on two same bits (0 and 0 or 1 and 1).

The MemoryError exception that you are seeing is the direct result of running out of available RAM. This could be caused by either the 2GB per program limit imposed by Windows (32bit programs), or lack of available RAM on your computer. (This link is to a previous question).

You should be able to extend the 2GB by using 64bit copy of Python, provided you are using a 64bit copy of windows.

The IndexError would be caused because Python hit the MemoryError exception before calculating the entire array. Again this is a memory issue.

To get around this problem you could try to use a 64bit copy of Python or better still find a way to write you results to file. To this end look at numpy's memory mapped arrays.

You should be able to run you entire set of calculation into one of these arrays as the actual data will be written disk, and only a small portion of it held in memory.

I could achieve a button using jQueryMobile with following code:

<label for="ppt" data-role="button" data-inline="true" data-mini="true" data-corners="false">Upload</label>
<input id="ppt" type="file" name="ppt" multiple data-role="button" data-inline="true" data-mini="true" data-corners="false" style="opacity: 0;"/>

Above code creates a "Upload" button (custom text). On click of upload button, file browse is launched. Tested with Chrome 25 & IE9.

There are a number of answers here with a misconception about git reset --soft. While there is a specific condition in which git reset --soft will only change HEAD (starting from a detached head state), typically (and for the intended use), it moves the branch reference you currently have checked out. Of course it can't do this if you don't have a branch checked out (hence the specific condition where git reset --soft will only change HEAD).

I've found this to be the best way to think about git reset. You're not just moving HEAD (everything does that), you're also moving the branch ref, e.g., master. This is similar to what happens when you run git commit (the current branch moves along with HEAD), except instead of creating (and moving to) a new commit, you move to a prior commit.

This is the point of reset, changing a branch to something other than a new commit, not changing HEAD. You can see this in the documentation example:

Undo a commit, making it a topic branch

          $ git branch topic/wip     (1)
          $ git reset --hard HEAD~3  (2)
          $ git checkout topic/wip   (3)

1. You have made some commits, but realize they were premature to be in the "master" branch. You want to continue polishing them in a topic branch, so create "topic/wip" branch off of the current HEAD.
2. Rewind the master branch to get rid of those three commits.
3. Switch to "topic/wip" branch and keep working.

What's the point of this series of commands? You want to move a branch, here master, so while you have master checked out, you run git reset.

The top voted answer here is generally good, but I thought I'd add this to correct the several answers with misconceptions.

Change your branch

git reset --soft <ref>: resets the branch pointer for the currently checked out branch to the commit at the specified reference, <ref>. Files in your working directory and index are not changed. Committing from this stage will take you right back to where you were before the git reset command.

Change your index too

git reset --mixed <ref>

or equivalently

git reset <ref>:

Does what --soft does AND also resets the index to the match the commit at the specified reference. While git reset --soft HEAD does nothing (because it says move the checked out branch to the checked out branch), git reset --mixed HEAD, or equivalently git reset HEAD, is a common and useful command because it resets the index to the state of your last commit.

Change your working directory too

git reset --hard <ref>: does what --mixed does AND also overwrites your working directory. This command is similar to git checkout <ref>, except that (and this is the crucial point about reset) all forms of git reset move the branch ref HEAD is pointing to.

A note about "such and such command moves the HEAD":

It is not useful to say a command moves the HEAD. Any command that changes where you are in your commit history moves the HEAD. That's what the HEAD is, a pointer to wherever you are. HEADis you, and so will move whenever you do.

I have made some researches on this subject recently. The way to implement it has to be different if the field is a TEXT field, a non unique field.

I have made some tests with a TEXT field. Considering the fact that we have a table with 1M entries. 37 entries are equal to 'something':

• SELECT * FROM test WHERE text LIKE '%something%' LIMIT 1 with mysql_num_rows() : 0.039061069488525s. (FASTER)
• SELECT count(*) as count FROM test WHERE text LIKE '%something% : 16.028197050095s.
• SELECT EXISTS(SELECT 1 FROM test WHERE text LIKE '%something%') : 0.87045907974243s.
• SELECT EXISTS(SELECT 1 FROM test WHERE text LIKE '%something%' LIMIT 1) : 0.044898986816406s.

But now, with a BIGINT PK field, only one entry is equal to '321321' :

• SELECT * FROM test2 WHERE id ='321321' LIMIT 1 with mysql_num_rows() : 0.0089840888977051s.
• SELECT count(*) as count FROM test2 WHERE id ='321321' : 0.00033879280090332s.
• SELECT EXISTS(SELECT 1 FROM test2 WHERE id ='321321') : 0.00023889541625977s.
• SELECT EXISTS(SELECT 1 FROM test2 WHERE id ='321321' LIMIT 1) : 0.00020313262939453s. (FASTER)

Edit this file (corresponding to your stopped container):

vi /var/lib/docker/containers/923...4f6/config.json

Change the "Path" parameter to point at your new command, e.g. /bin/bash. You may also set the "Args" parameter to pass arguments to the command.

Restart the docker service (note this will stop all running containers):

service docker restart

List your containers and make sure the command has changed:

docker ps -a

Start the container and attach to it, you should now be in your shell!

docker start -ai mad_brattain

Worked on Fedora 22 using Docker 1.7.1.

NOTE: If your shell is not interactive (e.g. you did not create the original container with -it option), you can instead change the command to "/bin/sleep 600" or "/bin/tail -f /dev/null" to give you enough time to do "docker exec -it CONTID /bin/bash" as another way of getting a shell.

NOTE2: Newer versions of docker have config.v2.json, where you will need to change either Entrypoint or Cmd (thanks user60561).

select partition_name,column_name,high_value,partition_position
from ALL_TAB_PARTITIONS a , ALL_PART_KEY_COLUMNS b 
where table_name='YOUR_TABLE' and a.table_name = b.name;

This query lists the column name used as key and the allowed values. make sure, you insert the allowed values(high_value). Else, if default partition is defined, it would go there.

EDIT:

I presume, your TABLE DDL would be like this.

CREATE TABLE HE0_DT_INF_INTERFAZ_MES
  (
    COD_PAIS NUMBER,
    FEC_DATA NUMBER,
    INTERFAZ VARCHAR2(100)
  )
  partition BY RANGE(COD_PAIS, FEC_DATA)
  (
    PARTITION PDIA_98_20091023 VALUES LESS THAN (98,20091024)
  );

Which means I had created a partition with multiple columns which holds value less than the composite range (98,20091024);

That is first COD_PAIS <= 98 and Also FEC_DATA < 20091024

Combinations And Result:

98, 20091024     FAIL
98, 20091023     PASS
99, ********     FAIL
97, ********     PASS
 < 98, ********     PASS

So the below INSERT fails with ORA-14400; because (98,20091024) in INSERT is EQUAL to the one in DDL but NOT less than it.

SQL> INSERT INTO HE0_DT_INF_INTERFAZ_MES(COD_PAIS, FEC_DATA, INTERFAZ)
                                  VALUES(98, 20091024, 'CTA');  2
INSERT INTO HE0_DT_INF_INTERFAZ_MES(COD_PAIS, FEC_DATA, INTERFAZ)
            *
ERROR at line 1:
ORA-14400: inserted partition key does not map to any partition

But, we I attempt (97,20091024), it goes through

SQL> INSERT INTO HE0_DT_INF_INTERFAZ_MES(COD_PAIS, FEC_DATA, INTERFAZ)
  2                                    VALUES(97, 20091024, 'CTA');

1 row created.

What about?

/.*\S.*/

This means

/ = delimiter
.* = zero or more of anything but newline
\S = anything except a whitespace (newline, tab, space)

so you get
match anything but newline + something not whitespace + anything but newline

sudo apt-get install ruby-dev

worked for me

This is by far the best SQLite library that I've used in Swift: https://github.com/stephencelis/SQLite.swift

Look at the code examples. So much cleaner than the C API:

import SQLite

let db = try Connection("path/to/db.sqlite3")

let users = Table("users")
let id = Expression<Int64>("id")
let name = Expression<String?>("name")
let email = Expression<String>("email")

try db.run(users.create { t in
    t.column(id, primaryKey: true)
    t.column(name)
    t.column(email, unique: true)
})
// CREATE TABLE "users" (
//     "id" INTEGER PRIMARY KEY NOT NULL,
//     "name" TEXT,
//     "email" TEXT NOT NULL UNIQUE
// )

let insert = users.insert(name <- "Alice", email <- "[email protected]")
let rowid = try db.run(insert)
// INSERT INTO "users" ("name", "email") VALUES ('Alice', '[email protected]')

for user in try db.prepare(users) {
    print("id: \(user[id]), name: \(user[name]), email: \(user[email])")
    // id: 1, name: Optional("Alice"), email: [email protected]
}
// SELECT * FROM "users"

let alice = users.filter(id == rowid)

try db.run(alice.update(email <- email.replace("mac.com", with: "me.com")))
// UPDATE "users" SET "email" = replace("email", 'mac.com', 'me.com')
// WHERE ("id" = 1)

try db.run(alice.delete())
// DELETE FROM "users" WHERE ("id" = 1)

try db.scalar(users.count) // 0
// SELECT count(*) FROM "users"

The documentation also says that "SQLite.swift also works as a lightweight, Swift-friendly wrapper over the C API," and follows with some examples of that.

The CSS property touch-action may get you what you are looking for, though it may not work in all your target browsers.

html, body {
    width: 100%; height: 100%;
    overflow: hidden;
    touch-action: none;
}

Short answer - yes, long answer: not how you want it.

You can use the %* form of printf, which accepts a variable width. And, if you use '0' as your value to print, combined with the right-aligned text that's zero padded on the left..

printf("%0*d\n", 20, 0);

produces:

00000000000000000000

With my tongue firmly planted in my cheek, I offer up this little horror-show snippet of code.

Some times you just gotta do things badly to remember why you try so hard the rest of the time.

#include <stdio.h>

int width = 20;
char buf[4096];

void subst(char *s, char from, char to) {
    while (*s == from)
    *s++ = to;
}

int main() {
    sprintf(buf, "%0*d", width, 0);
    subst(buf, '0', '-');
    printf("%s\n", buf);
    return 0;
}

Here's an example of using requestPermissions():

First, define the permission (as you did in your post) in the manifest, otherwise, your request will automatically be denied:

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

Next, define a value to handle the permission callback, in onRequestPermissionsResult():

private final int REQUEST_PERMISSION_PHONE_STATE=1;

Here's the code to call requestPermissions():

private void showPhoneStatePermission() {
    int permissionCheck = ContextCompat.checkSelfPermission(
            this, Manifest.permission.READ_PHONE_STATE);
    if (permissionCheck != PackageManager.PERMISSION_GRANTED) {
        if (ActivityCompat.shouldShowRequestPermissionRationale(this,
                Manifest.permission.READ_PHONE_STATE)) {
            showExplanation("Permission Needed", "Rationale", Manifest.permission.READ_PHONE_STATE, REQUEST_PERMISSION_PHONE_STATE);
        } else {
            requestPermission(Manifest.permission.READ_PHONE_STATE, REQUEST_PERMISSION_PHONE_STATE);
        }
    } else {
        Toast.makeText(MainActivity.this, "Permission (already) Granted!", Toast.LENGTH_SHORT).show();
    }
}

First, you check if you already have permission (remember, even after being granted permission, the user can later revoke the permission in the App Settings.)

And finally, this is how you check if you received permission or not:

@Override
public void onRequestPermissionsResult(
        int requestCode,
        String permissions[],
        int[] grantResults) {
    switch (requestCode) {
        case REQUEST_PERMISSION_PHONE_STATE:
            if (grantResults.length > 0
                    && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                Toast.makeText(MainActivity.this, "Permission Granted!", Toast.LENGTH_SHORT).show();
            } else {
                Toast.makeText(MainActivity.this, "Permission Denied!", Toast.LENGTH_SHORT).show();
            }
    }
}

private void showExplanation(String title,
                             String message,
                             final String permission,
                             final int permissionRequestCode) {
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle(title)
            .setMessage(message)
            .setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    requestPermission(permission, permissionRequestCode);
                }
            });
    builder.create().show();
}

private void requestPermission(String permissionName, int permissionRequestCode) {
    ActivityCompat.requestPermissions(this,
            new String[]{permissionName}, permissionRequestCode);
}

for /r %%v in (*.xls) do ssconvert "%%v" "%%vx"

a couple have people have asked me to explain this, so:

Part 1: for /r %%v in (*.xls)

This part returns an array of files in the current directory that have the xls extension. The %% may look a little curious. This is basically the special % character from command line as used in %PATH% or %TEMP%. To use it in a batch file we need to escape it like so: %%PATH%% or %%TEMP%%. In this case we are simply escaping the temporary variable v, which will hold our array of filenames.

We are using the /r switch to search for files recursively, so any matching files in child folders will also be located.

Part 2: do ssconvert "%%v" "%%vx"

This second part is what will get executed once per matching filename, so if the following files were present in the current folder:

c:\temp\mySheet.xls, c:\temp\mySheet_yesterday.xls, c:\temp\mySheet_20160902.xls

the following commands would be executed:

ssconvert "c:\temp\mySheet.xls" "c:\temp\mySheet.xlsx" ssconvert "c:\temp\mySheet_yesterday.xls" "c:\temp\mySheet_yesterday.xlsx" ssconvert "c:\temp\mySheet_20160902.xls" "c:\temp\mySheet_20160902.xlsx"

This one worked for me:

(?P<value>[-+]*\d+\.\d+|[-+]*\d+)

You can also use this one (without named parameter):

([-+]*\d+\.\d+|[-+]*\d+)

Use some online regex tester to test it (e.g. regex101 )

Since Java 8 you can use the Math.floorMod() method:

Math.floorMod(-1, 2); //== 1

Note: If the modulo-value (here 2) is negative, all output values will be negative too. :)

Source: https://stackoverflow.com/a/25830153/2311557

I was reading this page and they have an interesting sentence in there:

Caution: Be very selective when adding users to these roles. For example, sysadmin maps out to dbo in every database and is the equivalent of logging in using the sa account.

Of course, they also have this:

Permissions that are granted to users and roles and are database specific. All permissions are cumulative with the exception of a DENY. A denied permission at either a user level or at a role level overrides the same permission granted via other role memberships with the exception of the sysadmin fixed server role. (A sysadmin retains all permissions, even if a role they are a member of has a DENY permission.)

So if you're a domain admin and in SQL 'sysadmin' group, the world should be your crustacean.

Of course, according to Microsoft, you should be taking a quick look at these two pages:
Link to Database Prerequisites

Link to Installing Databases

You're being naughty and trying to attach them manually :) Seriously though, do you have all the prerequisites for the AdventureWorks2008 database?
I suspect this is just another Microsoft oddity/edge case, but I could be wrong.

@Multipart
@POST("user/updateprofile")
Observable<ResponseBody> updateProfile(@Part("user_id") RequestBody id,
                                       @Part("full_name") RequestBody fullName,
                                       @Part MultipartBody.Part image,
                                       @Part("other") RequestBody other);

//pass it like this
File file = new File("/storage/emulated/0/Download/Corrections 6.jpg");
RequestBody requestFile =
        RequestBody.create(MediaType.parse("multipart/form-data"), file);

// MultipartBody.Part is used to send also the actual file name
MultipartBody.Part body =
        MultipartBody.Part.createFormData("image", file.getName(), requestFile);

// add another part within the multipart request
RequestBody fullName = 
        RequestBody.create(MediaType.parse("multipart/form-data"), "Your Name");

service.updateProfile(id, fullName, body, other);

Look at the way I am passing the multipart and string params. Hope this will help you!

According to this site add

CONFIG += c++11

to your .pro file (see at the bottom of that web page). It requires Qt 5.

The other answers, suggesting

QMAKE_CXXFLAGS += -std=c++11 (or QMAKE_CXXFLAGS += -std=c++0x)

also work with Qt 4.8 and gcc / clang.

Change the customBinding in the web.config to use larger defaults. I picked 2MB as it is a reasonable size. Of course setting it to 2GB (as your code suggests) will work but it does leave you more vulnerable to attacks. Pick a size that is larger than your largest request but isn't overly large.

Try:

sudo /etc/init.d/mysql reload

or

sudo /etc/init.d/mysql force-reload

That should initiate a reload of the configuration. Make sureyour init.d script supports it though, I don't know what version of MySQL/OS you are using?

My MySQL script contains the following:

'reload'|'force-reload')
        log_daemon_msg "Reloading MySQL database server" "mysqld"
        $MYADMIN reload
        log_end_msg 0
        ;;

One way is to use DispatchQueue.main.asyncAfter as a lot of people have answered.

Another way is to use perform(_:with:afterDelay:). More details here

perform(#selector(delayedFunc), with: nil, afterDelay: 3)

@IBAction func delayedFunc() {
    // implement code
}

Have a look at the ReadAsset.java from API samples that come with the SDK.

       try {
        InputStream is = getAssets().open("read_asset.txt");

        // We guarantee that the available method returns the total
        // size of the asset...  of course, this does mean that a single
        // asset can't be more than 2 gigs.
        int size = is.available();

        // Read the entire asset into a local byte buffer.
        byte[] buffer = new byte[size];
        is.read(buffer);
        is.close();

        // Convert the buffer into a string.
        String text = new String(buffer);

        // Finally stick the string into the text view.
        TextView tv = (TextView)findViewById(R.id.text);
        tv.setText(text);
    } catch (IOException e) {
        // Should never happen!
        throw new RuntimeException(e);
    }

This will add an image to another.

using (Graphics grfx = Graphics.FromImage(image))

Use:

AND oh.tran_date BETWEEN TRUNC(SYSDATE - 1) AND TRUNC(SYSDATE) - 1/86400

Reference: TRUNC

Calling a function on the tran_date means the optimizer won't be able to use an index (assuming one exists) associated with it. Some databases, such as Oracle, support function based indexes which allow for performing functions on the data to minimize impact in such situations, but IME DBAs won't allow these. And I agree - they aren't really necessary in this instance.

Checkout this out. It takes care of daylight saving , leap year as it used iOS calendar to calculate.You can change the string and conditions to includes minutes with hours and days.

+(NSString*)remaningTime:(NSDate*)startDate endDate:(NSDate*)endDate
{
    NSDateComponents *components;
    NSInteger days;
    NSInteger hour;
    NSInteger minutes;
    NSString *durationString;

    components = [[NSCalendar currentCalendar] components: NSCalendarUnitDay|NSCalendarUnitHour|NSCalendarUnitMinute fromDate: startDate toDate: endDate options: 0];

    days = [components day];
    hour = [components hour];
    minutes = [components minute];

    if(days>0)
    {
        if(days>1)
            durationString=[NSString stringWithFormat:@"%d days",days];
        else
            durationString=[NSString stringWithFormat:@"%d day",days];
        return durationString;
    }
    if(hour>0)
    {        
        if(hour>1)
            durationString=[NSString stringWithFormat:@"%d hours",hour];

SetTimeout is used to make your set of code to execute after a specified time period so for your requirements its better to use setInterval because that will call your function every time at a specified time interval.

I tried restart: always, it works at some containers(like php-fpm), but i faced the problem that some containers(like nginx) is still not restarting after reboot.

Solved the problem.

crontab -e

@reboot (sleep 30s ; cd directory_has_dockercomposeyml ; /usr/local/bin/docker-compose up -d )&

Use the start command as follows.

start "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" http://www.google.com

It will be better to close chrome instances before you open a new one. You can do that as follows:

taskkill /IM chrome.exe
start "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" http://www.google.com

That'll work for you.

About REST return codes: it is wrong to mix HTTP protocol codes and REST results.

However, I saw many implementations mixing them, and many developers may not agree with me.

HTTP return codes are related to the HTTP Request itself. A REST call is done using a Hypertext Transfer Protocol request and it works at a lower level than invoked REST method itself. REST is a concept/approach, and its output is a business/logical result, while HTTP result code is a transport one.

For example, returning "404 Not found" when you call /users/ is confuse, because it may mean:

• URI is wrong (HTTP)
• No users are found (REST)

"403 Forbidden/Access Denied" may mean:

• Special permission needed. Browsers can handle it by asking the user/password. (HTTP)
• Wrong access permissions configured on the server. (HTTP)
• You need to be authenticated (REST)

And the list may continue with '500 Server error" (an Apache/Nginx HTTP thrown error or a business constraint error in REST) or other HTTP errors etc...

From the code, it's hard to understand what was the failure reason, a HTTP (transport) failure or a REST (logical) failure.

If the HTTP request physically was performed successfully it should always return 200 code, regardless is the record(s) found or not. Because URI resource is found and was handled by the http server. Yes, it may return an empty set. Is it possible to receive an empty web-page with 200 as http result, right?

Instead of this you may return 200 HTTP code and simply a JSON with an empty array/object, or to use a bool result/success flag to inform about the performed operation status.

Also, some internet providers may intercept your requests and return you a 404 http code. This does not means that your data are not found, but it's something wrong at transport level.

From Wiki:

In July 2004, the UK telecom provider BT Group deployed the Cleanfeed content blocking system, which returns a 404 error to any request for content identified as potentially illegal by the Internet Watch Foundation. Other ISPs return a HTTP 403 "forbidden" error in the same circumstances. The practice of employing fake 404 errors as a means to conceal censorship has also been reported in Thailand and Tunisia. In Tunisia, where censorship was severe before the 2011 revolution, people became aware of the nature of the fake 404 errors and created an imaginary character named "Ammar 404" who represents "the invisible censor".

Use PHP's fopen

The correct answer is

Options -Indexes

You must have been thinking of

AllowOverride All

https://httpd.apache.org/docs/2.2/howto/htaccess.html

.htaccess files (or "distributed configuration files") provide a way to make configuration changes on a per-directory basis. A file, containing one or more configuration directives, is placed in a particular document directory, and the directives apply to that directory, and all subdirectories thereof.

It would be easier to make suggestions if you provided example code and data.

Accessing the dictionary is unlikely to be a problem as that operation is O(1) on average, and O(N) amortized worst case. It's possible that the built-in hashing functions are experiencing collisions for your data. If you're having problems with has the built-in hashing function, you can provide your own.

Python's dictionary implementation reduces the average complexity of dictionary lookups to O(1) by requiring that key objects provide a "hash" function. Such a hash function takes the information in a key object and uses it to produce an integer, called a hash value. This hash value is then used to determine which "bucket" this (key, value) pair should be placed into.

You can overwrite the __hash__ method in your class to implement a custom hash function like this:

def __hash__(self):    
    return hash(str(self))

Depending on what your data actually looks like, you might be able to come up with a faster hash function that has fewer collisions than the standard function. However, this is unlikely. See the Python Wiki page on Dictionary Keys for more information.

while Alexey Kukanov's answer may be more efficient, you can also iterate through a queue in a very natural manner, by popping each element from the front of the queue, then pushing it to the back:

#include <iostream>
#include <queue>

using namespace std;

int main() {
    //populate queue
    queue<int> q;
    for (int i = 0; i < 10; ++i) q.push(i);

    // iterate through queue
    for (size_t i = 0; i < q.size(); ++i) {
        int elem = std::move(q.front());
        q.pop();
        elem *= elem;
        q.push(std::move(elem));
    }

    //print queue
    while (!q.empty()) {
        cout << q.front() << ' ';
        q.pop();
    }
}

output:

0 1 4 9 16 25 36 49 64 81 

In your model,

class Contact
  self.email_providers = %w[Gmail Yahoo MSN]
  validates :email_provider, :inclusion => email_providers
end

In your form,

<%= f.select :email_provider, 
    options_for_select(Contact.email_providers, @contact.email_provider) %>

the second arg of the options_for_select will have any current email_provider selected.

You can use:

event.stopPropagation();

The accepted solution for this will not work if you are planning to compile your scripts using py2exe. If you're planning to do so, this is the functional equivalent:

os.path.dirname(sys.argv[0])

Py2exe does not provide an __file__ variable. For reference: http://www.py2exe.org/index.cgi/Py2exeEnvironment

The solution I came up with is fragile; it relies on django's naming convention for foreign keys.

USE information_schema;
tee mysql_output
SELECT * FROM TABLE_CONSTRAINTS WHERE CONSTRAINT_TYPE = 'FOREIGN KEY' AND TABLE_SCHEMA = 'database_name';
notee

Then, in the shell,

grep 'refs_tablename_id' mysql_output

Also have a look at the PHPmailer class. PHPMailer

Performance

Today 2020.12.31 I perform tests on MacOs HighSierra 10.13.6 on Chrome v87, Safari v13.1.2 and Firefox v84 for chosen solutions for getting last N characters case (last letter case result, for clarity I present in separate answer).

Results

For all browsers

• solution D based on slice is fast or fastest
• solution G is slowest

You need to "clear" the float after every 6 images. So with your current code, change the styles for containerdivNewLine to:

.containerdivNewLine { clear: both; float: left; display: block; position: relative; } 

Just use an <a> by itself, set it to display: block; and set width and height. Get rid of the <span> and <div>. This is the semantic way to do it. There is no need to wrap things in <divs> (or any element) for layout. That is what CSS is for.

Demo: http://jsfiddle.net/ThinkingStiff/89Enq/

HTML:

<a id="music" href="Music.html">Music I Like</a>

CSS:

#music {
    background-color: black;
    color: white;
    display: block;
    height: 40px;
    line-height: 40px;
    text-decoration: none;
    width: 100px;
    text-align: center;
}

Try to use 3rd party tool, such as SQL Data Examiner which compares Oracle databases and shows you differences.

Default Usage

Get the meta for all keys:

<?php $meta = get_post_meta($post_id); ?>

Get the meta for a single key:

<?php $key_1_values = get_post_meta( 76, 'key_1' ); ?>

for example:

$myvals = get_post_meta($post_id);

foreach($myvals as $key=>$val)
{
    echo $key . ' : ' . $val[0] . '<br/>';
}

Note: some unwanted meta keys starting with "underscore(_)" will also come, so you will need to filter them out.

For reference: See Codex

It is impossible to detect and/or intercept the HOME button from within an Android app. This is built into the system to prevent malicious apps that cannot be exited.

I don't think this is possible. There appears to be an open Jira for it:

SPR-6702: Explicitly set response Content-Type in @ResponseBody

I cheated. Since the types I want to create (by name) are all in In a dll I control, I just put a static method in the dll in the assembly that takes a simple name, and calls type.GetType from that context and returns the result.

The original purpose was so that the type could be specified by name in configuration data. I've since change the code so that the user specified a format to process. The format handler classes implement a interface that determines if the type can parse the specified format. I then use reflection to find types that implement the interface, and find one that handles the format. So now the configuration specifies a format name, a not a specific type. The reflection code can look at adjacent dlls and load, them so I have a sort poor man's plug-in architecture.

• push = add to the stack
• pop = remove from the stack

There are a handful of options:

• NPOI - Which is free and open source.
• Aspose - Is definitely not free but robust.
• Spreadsheet ML - Basically XML for creating spreadsheets.

Using the Interop will require that the Excel be installed on the machine from which it is running. In a server side solution, this will be awful. Instead, you should use a tool like the ones above that lets you build an Excel file without Excel being installed.

If the user does not have Excel but has a tool that will read Excel (like Open Office), then obviously they will be able to open it. Microsoft has a free Excel viewer available for those users that do not have Excel.

i mentioned in the below where i have mentioned the custom filter also , how to call these filter which is having two parameters

countryApp.filter('reverse', function() {
    return function(input, uppercase) {
        var out = '';
        for (var i = 0; i < input.length; i++) {
            out = input.charAt(i) + out;
        }
        if (uppercase) {
            out = out.toUpperCase();
        }
        return out;
    }
});

and from the html using the template we can call that filter like below

<h1>{{inputString| reverse:true }}</h1>

here if you see , the first parameter is inputString and second parameter is true which is combined with "reverse' using the : symbol

For the record, you can also toy around URLs this way :

When browsing the latest source, you have something like : https://bitbucket.org/my/repo/src/latestcommithash/my.file?at=master

Simply change the commit hash and remove the GET parameter : https://bitbucket.org/my/repo/src/wantedcommithash/my.file

Got to +1 @Hein A. Grønnestad above : it's all working, really wondering why there's nothing in the GUI to use it.

Tip #84: Did you know… How to set a Start page for your Web Site in Visual Web Developer?

Simply right click on the page you want to be the start page and say "set as start page".

As noted in the comment below by Adam Tuliper - MSFT, this only works for debugging, not deployment.

Some people find the following alternative syntax easier to see what is going on:

select t1.value,t2.value
from MyTable t1
    inner join MyTable t2 on
        t1.id = t2.id
where t1.id = @id

You can get all the required file properties by using the code below:

FOR %%? IN (file_to_be_queried) DO (
    ECHO File Name Only       : %%~n?
    ECHO File Extension       : %%~x?
    ECHO Name in 8.3 notation : %%~sn?
    ECHO File Attributes      : %%~a?
    ECHO Located on Drive     : %%~d?
    ECHO File Size            : %%~z?
    ECHO Last-Modified Date   : %%~t?
    ECHO Parent Folder        : %%~dp?
    ECHO Fully Qualified Path : %%~f?
    ECHO FQP in 8.3 notation  : %%~sf?
    ECHO Location in the PATH : %%~dp$PATH:?
)

I'd like to recommend ack -- better than grep, a power search tool for programmers.

$ ack --color --passthru --pager="${PAGER:-less -R}" pattern files

$ ack --color --passthru pattern files | less -R

$ export ACK_PAGER_COLOR="${PAGER:-less -R}"
$ ack --passthru pattern files

I love it because it defaults to recursive searching of directories (and does so much smarter than grep -r), supports full Perl regular expressions (rather than the POSIXish regex(3)), and has a much nicer context display when searching many files.

You can use an anonymous function to pass the matches to your function:

$result = preg_replace_callback(
    "/\{([<>])([a-zA-Z0-9_]*)(\?{0,1})([a-zA-Z0-9_]*)\}(.*)\{\\1\/\\2\}/isU",
    function($m) { return CallFunction($m[1], $m[2], $m[3], $m[4], $m[5]); },
    $result
);

Apart from being faster, this will also properly handle double quotes in your string. Your current code using /e would convert a double quote " into \".

JavaScript is object-oriented, but it's radically different than other OOP languages like Java, C# or C++. Don't try to understand it like that. Throw that old knowledge out and start anew. JavaScript needs a different thinking.

I'd suggest to get a good manual or something on the subject. I myself found ExtJS Tutorials the best for me, although I haven't used the framework before or after reading it. But it does give a good explanation about what is what in JavaScript world. Sorry, it seems that that content has been removed. Here's a link to archive.org copy instead. Works today. :P

A couple of changes mean that only an R or r will roll. Any other character will quit

import random

while True:
    print('Your score so far is {}.'.format(myScore))
    print("Would you like to roll or quit?")
    ans = input("Roll...")
    if ans.lower() == 'r':
        R = np.random.randint(1, 8)
        print("You rolled a {}.".format(R))
        myScore = R + myScore
    else:
        print("Now I'll see if I can break your score...")
        break

/(?:http[s]?\/\/)?(?:[\w\-]+(?::[\w\-]+)?@)?(?:[\w\-]+\.)+(?:[a-z]{2,4})(?::[0-9]+)?(?:\/[\w\-\.%]+)*(?:\?(?:[\w\-\.%]+=[\w\-\.%!]+&?)+)?(#\w+\-\.%!)?/

This worked for me as well:

Get-ADUser -Filter * -SearchBase "ou=OU,dc=Domain,dc=com" -Properties Enabled, CanonicalName, Displayname, Givenname, Surname, EmployeeNumber, EmailAddress, Department, StreetAddress, Title | select Enabled, CanonicalName, Displayname, GivenName, Surname, EmployeeNumber, EmailAddress, Department, Title | Export-CSV "C:\output.csv"

Try this. Copy this into a batch file - such as send.bat - and then simply run send.bat to send the message from the temperature program to the prismcom program.

temperature.exe > msg.txt
set /p msg= < msg.txt
prismcom.exe usb "%msg%"

best and simple

requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

Here is the code I've just implemented. This is not a method but you can use it as a ready-to-use function!

def inttobinary(number):
  if number == 0:
    return str(0)
  result =""
  while (number != 0):
      remainder = number%2
      number = number/2
      result += str(remainder)
  return result[::-1] # to invert the string

The language spec mentions comparison operators' behaviors:

comparison operators

In any comparison, the first operand must be assignable to the type of the second operand, or vice versa.

Assignability

A value x is assignable to a variable of type T ("x is assignable to T") in any of these cases:

• x's type is identical to T.
• x's type V and T have identical underlying types and at least one of V or T is not a named type.
• T is an interface type and x implements T.
• x is a bidirectional channel value, T is a channel type, x's type V and T have identical element types, and at least one of V or T is not a named type.
• x is the predeclared identifier nil and T is a pointer, function, slice, map, channel, or interface type.
• x is an untyped constant representable by a value of type T.

<xsl:call-template> is a close equivalent to calling a function in a traditional programming language.

You can define functions in XSLT, like this simple one that outputs a string.

<xsl:template name="dosomething">
  <xsl:text>A function that does something</xsl:text>
</xsl:template>

This function can be called via <xsl:call-template name="dosomething">.

<xsl:apply-templates> is a little different and in it is the real power of XSLT: It takes any number of XML nodes (whatever you define in the select attribute), iterates them (this is important: apply-templates works like a loop!) and finds matching templates for them:

<!-- sample XML snippet -->
<xml>
  <foo /><bar /><baz />
</xml>

<!-- sample XSLT snippet -->
<xsl:template match="xml">
  <xsl:apply-templates select="*" /> <!-- three nodes selected here -->
</xsl:template>

<xsl:template match="foo"> <!-- will be called once -->
  <xsl:text>foo element encountered</xsl:text>
</xsl:template>

<xsl:template match="*"> <!-- will be called twice -->
  <xsl:text>other element countered</xsl:text>
</xsl:template>

This way you give up a little control to the XSLT processor - not you decide where the program flow goes, but the processor does by finding the most appropriate match for the node it's currently processing.

If multiple templates can match a node, the one with the more specific match expression wins. If more than one matching template with the same specificity exist, the one declared last wins.

You can concentrate more on developing templates and need less time to do "plumbing". Your programs will become more powerful and modularized, less deeply nested and faster (as XSLT processors are optimized for template matching).

A concept to understand with XSLT is that of the "current node". With <xsl:apply-templates> the current node moves on with every iteration, whereas <xsl:call-template> does not change the current node. I.e. the . within a called template refers to the same node as the . in the calling template. This is not the case with apply-templates.

This is the basic difference. There are some other aspects of templates that affect their behavior: Their mode and priority, the fact that templates can have both a name and a match. It also has an impact whether the template has been imported (<xsl:import>) or not. These are advanced uses and you can deal with them when you get there.

You want reorder(). Here is an example with dummy data

set.seed(42)
df <- data.frame(Category = sample(LETTERS), Count = rpois(26, 6))

require("ggplot2")

p1 <- ggplot(df, aes(x = Category, y = Count)) +
         geom_bar(stat = "identity")

p2 <- ggplot(df, aes(x = reorder(Category, -Count), y = Count)) +
         geom_bar(stat = "identity")

require("gridExtra")
grid.arrange(arrangeGrob(p1, p2))

Giving:

Use reorder(Category, Count) to have Category ordered from low-high.

I'm using this one:

  internal static bool IsValidJson(string data)
  {
     data = data.Trim();
     try
     {
        if (data.StartsWith("{") && data.EndsWith("}"))
        {
           JToken.Parse(data);
        }
        else if (data.StartsWith("[") && data.EndsWith("]"))
        {
           JArray.Parse(data);
        }
        else
        {
           return false;
        }
        return true;
     }
     catch
     {
        return false;
     }
  }

Did you try list(x)??

 y = '+123-456-7890'
 c =list(y)
 c

['+', '1', '2', '3', '-', '4', '5', '6', '-', '7', '8', '9', '0']

Here is code I have used for Capturing and Saving Camera Image then display it to imageview. You can use according to your need.

You have to save Camera image to specific location then fetch from that location then convert it to byte-array.

Here is method for opening capturing camera image activity.

private static final int CAMERA_PHOTO = 111;
private Uri imageToUploadUri;

private void captureCameraImage() {
        Intent chooserIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        File f = new File(Environment.getExternalStorageDirectory(), "POST_IMAGE.jpg");
        chooserIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
        imageToUploadUri = Uri.fromFile(f);
        startActivityForResult(chooserIntent, CAMERA_PHOTO);
    }

then your onActivityResult() method should be like this.

@Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            super.onActivityResult(requestCode, resultCode, data);

            if (requestCode == CAMERA_PHOTO && resultCode == Activity.RESULT_OK) {
                if(imageToUploadUri != null){
                    Uri selectedImage = imageToUploadUri;
                    getContentResolver().notifyChange(selectedImage, null);
                    Bitmap reducedSizeBitmap = getBitmap(imageToUploadUri.getPath());
                    if(reducedSizeBitmap != null){
                        ImgPhoto.setImageBitmap(reducedSizeBitmap);
                        Button uploadImageButton = (Button) findViewById(R.id.uploadUserImageButton);
                          uploadImageButton.setVisibility(View.VISIBLE);                
                    }else{
                        Toast.makeText(this,"Error while capturing Image",Toast.LENGTH_LONG).show();
                    }
                }else{
                    Toast.makeText(this,"Error while capturing Image",Toast.LENGTH_LONG).show();
                }
            } 
        }

Here is getBitmap() method used in onActivityResult(). I have done all performance improvement that can be possible while getting camera capture image bitmap.

private Bitmap getBitmap(String path) {

        Uri uri = Uri.fromFile(new File(path));
        InputStream in = null;
        try {
            final int IMAGE_MAX_SIZE = 1200000; // 1.2MP
            in = getContentResolver().openInputStream(uri);

            // Decode image size
            BitmapFactory.Options o = new BitmapFactory.Options();
            o.inJustDecodeBounds = true;
            BitmapFactory.decodeStream(in, null, o);
            in.close();


            int scale = 1;
            while ((o.outWidth * o.outHeight) * (1 / Math.pow(scale, 2)) >
                    IMAGE_MAX_SIZE) {
                scale++;
            }
            Log.d("", "scale = " + scale + ", orig-width: " + o.outWidth + ", orig-height: " + o.outHeight);

            Bitmap b = null;
            in = getContentResolver().openInputStream(uri);
            if (scale > 1) {
                scale--;
                // scale to max possible inSampleSize that still yields an image
                // larger than target
                o = new BitmapFactory.Options();
                o.inSampleSize = scale;
                b = BitmapFactory.decodeStream(in, null, o);

                // resize to desired dimensions
                int height = b.getHeight();
                int width = b.getWidth();
                Log.d("", "1th scale operation dimenions - width: " + width + ", height: " + height);

                double y = Math.sqrt(IMAGE_MAX_SIZE
                        / (((double) width) / height));
                double x = (y / height) * width;

                Bitmap scaledBitmap = Bitmap.createScaledBitmap(b, (int) x,
                        (int) y, true);
                b.recycle();
                b = scaledBitmap;

                System.gc();
            } else {
                b = BitmapFactory.decodeStream(in);
            }
            in.close();

            Log.d("", "bitmap size - width: " + b.getWidth() + ", height: " +
                    b.getHeight());
            return b;
        } catch (IOException e) {
            Log.e("", e.getMessage(), e);
            return null;
        }
    }

Hope it helps!

there any rule I can follow to be sure that my app executes my own code just in the main thread?

Typically you wouldn't need to do anything to ensure this — your list of things is usually enough. Unless you're interacting with some API that happens to spawn a thread and run your code in the background, you'll be running on the main thread.

If you want to be really sure, you can do things like

[self performSelectorOnMainThread:@selector(myMethod:) withObject:anObj waitUntilDone:YES];

to execute a method on the main thread. (There's a GCD equivalent too.)

This is many years late but since I found the solution I'll post it here. By using maps it is possible to do what was asked:

map $http_host $variable_name {
    hostnames;

    default       /ap/;
    example.com   /api/;
    *.example.org /whatever/;
}

server {
    location $variable_name/test {
        proxy_pass $auth_proxy;
    }
}

If you need to share the same endpoint across multiple servers, you can also reduce the cost by simply defaulting the value:

map "" $variable_name {
    default       /test/;
}

Map can be used to initialise a variable based on the content of a string and can be used inside http scope allowing variables to be global and sharable across servers.

You want to try String.format("%f", d), which will print your double in decimal notation. Don't use BigDecimal at all.

Regarding the precision issue: You are first storing 47.48 in the double c, then making a new BigDecimal from that double. The loss of precision is in assigning to c. You could do

BigDecimal b = new BigDecimal("47.48")

to avoid losing any precision.

In the spring jar package, I use new ClassPathResource(filename).getFile(), which throws the exception:

cannot be resolved to absolute file path because it does not reside in the file system: jar

But using new ClassPathResource(filename).getInputStream() will solve this problem. The reason is that the configuration file in the jar does not exist in the operating system's file tree,so must use getInputStream().

if you are using IIS, maybe you should try
"application pools" --> "DefaultAppPool" --> "application pools default value" --> "32-Bit-application-activ" --> set false

I found the best way to do this is with ChronoUnit.

long minutes = ChronoUnit.MINUTES.between(fromDate, toDate);
long hours = ChronoUnit.HOURS.between(fromDate, toDate);

Additional documentation is here: https://docs.oracle.com/javase/tutorial/datetime/iso/period.html

Eager Loading When you are sure that want to get multiple entities at a time, for example you have to show user, and user details at the same page, then you should go with eager loading. Eager loading makes single hit on database and load the related entities.

Lazy loading When you have to show users only at the page, and by clicking on users you need to show user details then you need to go with lazy loading. Lazy loading make multiple hits, to get load the related entities when you bind/iterate related entities.

Has anyone mentioned std::call_once and std::once_flag? Most other approaches - including double checked locking - are broken.

One major problem in singleton pattern implementation is safe initialization. The only safe way is to guard the initialization sequence with synchronizing barriers. But those barriers themselves need to be safely initiated. std::once_flag is the mechanism to get guaranteed safe initialization.

import matplotlib.pyplot as plt

fig, ax = plt.subplots(2, 2)

To turn off axes for all subplots, do either:

[axi.set_axis_off() for axi in ax.ravel()]

or

map(lambda axi: axi.set_axis_off(), ax.ravel())

This will work...

echo date('m/d/y H:i (A)',strtotime($data_from_mysql));

Nothing worked and finally got it working using resource @Here and Here; Just remember for OSX Mavericks (10.9) should use PHP 5.4.17 or Stable PHP 5.4.22 source to compile mcrypt. Php Source 5.4.22 here

select * from [member] where DatePart("m", date_created) = DatePart("m", DateAdd("m", -1, getdate())) AND DatePart("yyyy", date_created) = DatePart("yyyy", DateAdd("m", -1, getdate()))

e.printStackTrace equivalent in python

In Java, this does the following (docs):

public void printStackTrace()

Prints this throwable and its backtrace to the standard error stream...

This is used like this:

try
{ 
// code that may raise an error
}
catch (IOException e)
{
// exception handling
e.printStackTrace();
}

In Java, the Standard Error stream is unbuffered so that output arrives immediately.

The same semantics in Python 2 are:

import traceback
import sys
try: # code that may raise an error
    pass 
except IOError as e: # exception handling
    # in Python 2, stderr is also unbuffered
    print >> sys.stderr, traceback.format_exc()
    # in Python 2, you can also from __future__ import print_function
    print(traceback.format_exc(), file=sys.stderr)
    # or as the top answer here demonstrates, use:
    traceback.print_exc()
    # which also uses stderr.

Python 3

In Python 3, we can get the traceback directly from the exception object (which likely behaves better for threaded code). Also, stderr is line-buffered, but the print function gets a flush argument, so this would be immediately printed to stderr:

    print(traceback.format_exception(None, # <- type(e) by docs, but ignored 
                                     e, e.__traceback__),
          file=sys.stderr, flush=True)

Conclusion:

In Python 3, therefore, traceback.print_exc(), although it uses sys.stderr by default, would buffer the output, and you may possibly lose it. So to get as equivalent semantics as possible, in Python 3, use print with flush=True.

Two main reasons why .Select, .Activate, Selection, Activecell, Activesheet, Activeworkbook, etc. should be avoided

1. It slows down your code.
2. It is usually the main cause of runtime errors.

How do we avoid it?

1) Directly work with the relevant objects

Consider this code

Sheets("Sheet1").Activate
Range("A1").Select
Selection.Value = "Blah"
Selection.NumberFormat = "@"

This code can also be written as

With Sheets("Sheet1").Range("A1")
    .Value = "Blah"
    .NumberFormat = "@"
End With

2) If required declare your variables. The same code above can be written as

Dim ws as worksheet

Set ws = Sheets("Sheet1")

With ws.Range("A1")
    .Value = "Blah"
    .NumberFormat = "@"
End With

Change your code to the following :

Function Foo($directory)
    {
        echo $directory
    }

    if ($args.Length -eq 0)
    {
        echo "Usage: Foo <directory>"
    }
    else
    {
        Foo([string[]]$args)
    }

And then invoke it as:

powershell -ExecutionPolicy RemoteSigned -File "c:\foo.ps1" "c:\Documents and Settings" "c:\test"

Take a look at Behaviour of increment and decrement operators in Python for an explanation of why this doesn't work.

Python doesn't really have ++ and --, and I personally never felt it was such a loss.

I prefer functions with clear names to operators with non-always clear semantics (hence the classic interview question about ++x vs. x++ and the difficulties of overloading it). I've also never been a huge fan of what post-incrementation does for readability.

You could always define some wrapper class (like accumulator) with clear increment semantics, and then do something like x.increment() or x.incrementAndReturnPrev()

You can use this function to get the absolute value:

+(NSNumber *)absoluteValue:(NSNumber *)input {
  return [NSNumber numberWithDouble:fabs([input doubleValue])];
}
