I think this comes closest to what you wish:

(From IntelliJ IDEA Q&A for Eclipse Users):

The above can be combined with a recently introduced option in Compiler settings to get a view very similar to that of Eclipse.

Things to do:

1. Switch to 'Problems' view in the Project pane:
   
   

2. Enable the setting to compile the project automatically :
   
   

3. Finally, look at the Problems view:
   
   

Here is a comparison of what the same project (with a compilation error) looks like in Intellij IDEA 13.xx and Eclipse Kepler:

Relevant Links: The maven project shown above : https://github.com/ajorpheus/CompileTimeErrors
FAQ For 'Eclipse Mode' / 'Automatically Compile' a project : http://devnet.jetbrains.com/docs/DOC-1122

I am trying to do something similar to this. As commented above, I think you would want to build a new image with a custom Dockerfile (using the image you pulled as a base image), ADD your certificate, then RUN update-ca-certificates. This way you will have a consistent state each time you start a container from this new image.

# Dockerfile
FROM some-base-image:0.1
ADD you_certificate.crt:/container/cert/path
RUN update-ca-certificates

Let's say a docker build against that Dockerfile produced IMAGE_ID. On the next docker run -d [any other options] IMAGE_ID, the container started by that command will have your certificate info. Simple and reproducible.

It's the other way around: B.class.isInstance(view)

You could start by reading the documentation for Date. Then you realize that Date’s methods are all deprecated and turn to Calender instead.

Calendar now = Calendar.getInstance();
System.out.println(now.get(Calendar.DAY_OF_MONTH));

In addition to @tadman's answer I removed the wrappers in /usr/local/bin as well as the file /etc/profile.d/rvm.

The wrappers include:

erb
gem
irb
rake
rdoc
ri
ruby
testrb

Try to use it this way:

let current_time = moment().format("HH:mm")

A lot of good solutions and valuable commentaries by known experts from JS community on the topic could be found here. It could be an indicator that it's not that trivial problem as it may seem. I think this is why it could be the source of doubts and uncertainty on the issue.

Fundamental problem here is that in React you're only allowed to mount component to its parent, which is not always the desired behavior. But how to address this issue?

I propose the solution, addressed to fix this issue. More detailed problem definition, src and examples can be found here: https://github.com/fckt/react-layer-stack#rationale

Rationale

react/react-dom comes comes with 2 basic assumptions/ideas:

• every UI is hierarchical naturally. This why we have the idea of components which wrap each other
• react-dom mounts (physically) child component to its parent DOM node by default

The problem is that sometimes the second property isn't what you want in your case. Sometimes you want to mount your component into different physical DOM node and hold logical connection between parent and child at the same time.

Canonical example is Tooltip-like component: at some point of development process you could find that you need to add some description for your UI element: it'll render in fixed layer and should know its coordinates (which are that UI element coord or mouse coords) and at the same time it needs information whether it needs to be shown right now or not, its content and some context from parent components. This example shows that sometimes logical hierarchy isn't match with the physical DOM hierarchy.

Take a look at https://github.com/fckt/react-layer-stack/blob/master/README.md#real-world-usage-example to see the concrete example which is answer to your question:

import { Layer, LayerContext } from 'react-layer-stack'
// ... for each `object` in array of `objects`
  const modalId = 'DeleteObjectConfirmation' + objects[rowIndex].id
  return (
    <Cell {...props}>
        // the layer definition. The content will show up in the LayerStackMountPoint when `show(modalId)` be fired in LayerContext
        <Layer use={[objects[rowIndex], rowIndex]} id={modalId}> {({
            hideMe, // alias for `hide(modalId)`
            index } // useful to know to set zIndex, for example
            , e) => // access to the arguments (click event data in this example)
          <Modal onClick={ hideMe } zIndex={(index + 1) * 1000}>
            <ConfirmationDialog
              title={ 'Delete' }
              message={ "You're about to delete to " + '"' + objects[rowIndex].name + '"' }
              confirmButton={ <Button type="primary">DELETE</Button> }
              onConfirm={ this.handleDeleteObject.bind(this, objects[rowIndex].name, hideMe) } // hide after confirmation
              close={ hideMe } />
          </Modal> }
        </Layer>

        // this is the toggle for Layer with `id === modalId` can be defined everywhere in the components tree
        <LayerContext id={ modalId }> {({showMe}) => // showMe is alias for `show(modalId)`
          <div style={styles.iconOverlay} onClick={ (e) => showMe(e) }> // additional arguments can be passed (like event)
            <Icon type="trash" />
          </div> }
        </LayerContext>
    </Cell>)
// ...

Modify to suit your specifics, or make more generic as needed:

Private Sub CopyItOver()
  Set NewBook = Workbooks.Add
  Workbooks("Whatever.xlsx").Worksheets("output").Range("A1:K10").Copy
  NewBook.Worksheets("Sheet1").Range("A1").PasteSpecial (xlPasteValues)
  NewBook.SaveAs FileName:=NewBook.Worksheets("Sheet1").Range("E3").Value
End Sub

This builds on the answer from JaredPar... and is for VS2017. The same "Build and Run" options are present in Visual Studio 2017.

I was getting, The command "chmod +x """ exited with code 1

In the build output window, I searched for "Error" and found a few errors in the same general area. I was able to click on a link in the build output, and found that the error involved this entry in the .targets file:

  <Target Name="ChmodChromeDriver" BeforeTargets="BeforeBuild" Condition="'$(WebDriverPlatform)' != 'win32'">
    <Exec Command="chmod +x &quot;$(ChromeDriverSrcPath)&quot;" />
  </Target>

In the build output, I also found a more detailed error message that essentially stated that it couldn't find Selenium.WebDriver.ChromeDriver v2.36 in the packages folder it was looking in. I checked the project's NuGet packages, and version 2.36 was indeed in the list of installed packages. I did find the package files for 2.36, and changed the attributes on the folder, subfolders and files from "Read Only" to "Read/Write". Built, but same failure. Sometimes "updating" to a different version of the package and then updating back to the original can fix this type of error. So I "updated" the reference in Manage NuGet packages to 2.37, built, failed, then "updated" back to 2.36, built, and the build succeeded without the "chmod +x" error message.

The project I was building was based on a Visual Studio Project template for Appium test tooling, template name "Develop_Automated_Test".

I collected and tested discussed solutions:

Windows10 Prof x64:

* FireFox v.56.0 x32 
* Opera v.49.0
* Google Chrome v.61.0.3163.100 x64-bit

macOs X Serra v.10.12.6 Mac mini (Mid 2010):

* Safari v.10.1.2(12603.3.8)
* FireFox v.57.0 Quantum
* Opera v49.0

Semi (still micro fat in Safari) solved fatty fonts:

text-transform: none; // mac ff fix
-webkit-font-smoothing: antialiased; // safari mac nicer
-moz-osx-font-smoothing: grayscale; // fix fatty ff on mac

Have no visual effect

line-height: 1;
text-rendering: optimizeLegibility; 
speak: none;
font-style: normal;
font-variant: normal;

Wrong visual effect:

-webkit-font-smoothing: subpixel-antialiased !important; //more fatty in safari
text-rendering: geometricPrecision !important; //more fatty in safari

do not forget to set !important when testing or be sure that your style is not overridden

The accepted answer works great if you just want to use a different context in your partial. However, it doesn't let you reference any of the parent context. To pass in multiple arguments, you need to write your own helper. Here's a working helper for Handlebars 2.0.0 (the other answer works for versions <2.0.0):

Handlebars.registerHelper('renderPartial', function(partialName, options) {
    if (!partialName) {
        console.error('No partial name given.');
        return '';
    }
    var partial = Handlebars.partials[partialName];
    if (!partial) {
        console.error('Couldnt find the compiled partial: ' + partialName);
        return '';
    }
    return new Handlebars.SafeString( partial(options.hash) );
});

Then in your template, you can do something like:

{{renderPartial 'myPartialName' foo=this bar=../bar}}

And in your partial, you'll be able to access those values as context like:

<div id={{bar.id}}>{{foo}}</div>

In light of apparent dislike for how I've attempted to answer the OP's question. The literal answer is, a promise is something shared w/ other objects, while a deferred should be kept private. Primarily, a deferred (which generally extends Promise) can resolve itself, while a promise might not be able to do so.

If you're interested in the minutiae, then examine Promises/A+.

So far as I'm aware, the overarching purpose is to improve clarity and loosen coupling through a standardized interface. See suggested reading from @jfriend00:

Rather than directly passing callbacks to functions, something which can lead to tightly coupled interfaces, using promises allows one to separate concerns for code that is synchronous or asynchronous.

Personally, I've found deferred especially useful when dealing with e.g. templates that are populated by asynchronous requests, loading scripts that have networks of dependencies, and providing user feedback to form data in a non-blocking manner.

Indeed, compare the pure callback form of doing something after loading CodeMirror in JS mode asynchronously (apologies, I've not used jQuery in a while):

/* assume getScript has signature like: function (path, callback, context) 
   and listens to onload && onreadystatechange */
$(function () {
   getScript('path/to/CodeMirror', getJSMode);

   // onreadystate is not reliable for callback args.
   function getJSMode() {
       getScript('path/to/CodeMirror/mode/javascript/javascript.js', 
           ourAwesomeScript);
   };

   function ourAwesomeScript() {
       console.log("CodeMirror is awesome, but I'm too impatient.");
   };
});

To the promises formulated version (again, apologies, I'm not up to date on jQuery):

/* Assume getScript returns a promise object */
$(function () {
   $.when(
       getScript('path/to/CodeMirror'),
       getScript('path/to/CodeMirror/mode/javascript/javascript.js')
   ).then(function () {
       console.log("CodeMirror is awesome, but I'm too impatient.");
   });
});

Apologies for the semi-pseudo code, but I hope it makes the core idea somewhat clear. Basically, by returning a standardized promise, you can pass the promise around, thus allowing for more clear grouping.

I tested and the script run ok!

Configuration

You can enable GZIP compression entirely in your Web.config file. This is particularly useful if you're on shared hosting and can't configure IIS directly, or you want your config to carry between all environments you target.

<system.webServer>
  <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files">
    <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll"/>
    <dynamicTypes>
      <add mimeType="text/*" enabled="true"/>
      <add mimeType="message/*" enabled="true"/>
      <add mimeType="application/javascript" enabled="true"/>
      <add mimeType="*/*" enabled="false"/>
    </dynamicTypes>
    <staticTypes>
      <add mimeType="text/*" enabled="true"/>
      <add mimeType="message/*" enabled="true"/>
      <add mimeType="application/javascript" enabled="true"/>
      <add mimeType="*/*" enabled="false"/>
    </staticTypes>
  </httpCompression>
  <urlCompression doStaticCompression="true" doDynamicCompression="true"/>
</system.webServer>

Testing

To test whether compression is working or not, use the developer tools in Chrome or Firebug for Firefox and ensure the HTTP response header is set:

Content-Encoding: gzip

Note that this header won't be present if the response code is 304 (Not Modified). If that's the case, do a full refresh (hold shift or control while you press the refresh button) and check again.

SURE: Simply,

This is what you need :

io.to(socket.id).emit("event", data);

whenever a user joined to the server, socket details will be generated including ID. This is the ID really helps to send a message to particular people.

first we need to store all the socket.ids in array,

var people={};

people[name] =  socket.id;

here name is the receiver name. Example:

people["ccccc"]=2387423cjhgfwerwer23;

So, now we can get that socket.id with the receiver name whenever we are sending message:

for this we need to know the receivername. You need to emit receiver name to the server.

final thing is:

 socket.on('chat message', function(data){
io.to(people[data.receiver]).emit('chat message', data.msg);
});

Hope this works well for you.

Good Luck!!

Another useful way of doing it that I use is unions:

union byteint
{
    byte b[sizeof int];
    int i;
};
byteint bi;
bi.i = 1337;
for(int i = 0; i<4;i++)
    destination[i] = bi.b[i];

This will make it so that the byte array and the integer will "overlap"( share the same memory ). this can be done with all kinds of types, as long as the byte array is the same size as the type( else one of the fields will not be influenced by the other ). And having them as one object is also just convenient when you have to switch between integer manipulation and byte manipulation/copying.

To make the code more clear that Kahia wrote in (it is clear but gets tricky when you want to add more text to it)...try this simple solution.

if (Math.Round((decimal)user.CurrentPoints) == user.CurrentPoints)
     ViewBag.MyCurrentPoints = String.Format("Your current Points: {0:0}",user.CurrentPoints);
else
     ViewBag.MyCurrentPoints = String.Format("Your current Points: {0:0.0}",user.CurrentPoints);

I had to add the extra cast (decimal) to have Math.Round compare the two decimal variables.

This worked for me:

BufferedImage bufImgs = ImageIO.read(new File("c:\\adi.bmp"));    
double[][] data = new double[][];
bufImgs.getData().getPixels(0,0,bufImgs.getWidth(),bufImgs.getHeight(),data[i]);

You need something like a full outer join. System.Linq.Enumerable has no method that implements a full outer join, so we have to do it ourselves.

var dict1 = list1.ToDictionary(l1 => l1.Name);
var dict2 = list2.ToDictionary(l2 => l2.Name);
    //get the full list of names.
var names = dict1.Keys.Union(dict2.Keys).ToList();
    //produce results
var result = names
.Select( name =>
{
  Person p1 = dict1.ContainsKey(name) ? dict1[name] : null;
  Person p2 = dict2.ContainsKey(name) ? dict2[name] : null;
      //left only
  if (p2 == null)
  {
    p1.Change = 0;
    return p1;
  }
      //right only
  if (p1 == null)
  {
    p2.Change = 0;
    return p2;
  }
      //both
  p2.Change = p2.Value - p1.Value;
  return p2;
}).ToList();

@RequestMapping is a class level

@GetMapping is a method-level

With sprint Spring 4.3. and up things have changed. Now you can use @GetMapping on the method that will handle the http request. The class-level @RequestMapping specification is refined with the (method-level)@GetMapping annotation

Here is an example:

@Slf4j
@Controller
@RequestMapping("/orders")/* The @Request-Mapping annotation, when applied
                            at the class level, specifies the kind of requests 
                            that this controller handles*/  

public class OrderController {

@GetMapping("/current")/*@GetMapping paired with the classlevel
                        @RequestMapping, specifies that when an 
                        HTTP GET request is received for /order, 
                        orderForm() will be called to handle the request..*/

public String orderForm(Model model) {

model.addAttribute("order", new Order());

return "orderForm";
}
}

Prior to Spring 4.3, it was @RequestMapping(method=RequestMethod.GET)

I am making an assumption that there is a counter already in place. in $i which is incremented at the end of a loop, This works for me using a shorthand query.

$row_pos = ($i & 1) ? 'odd' : 'even';

So what does this do, well it queries the statement we are making in essence $i is odd, depending whether its true or false will decide what gets returned. The returned value populates our variable $row_pos

My use of this is to place it inside the foreach loop, right before i need it, This makes it a very efficient one liner to give me the appropriate class names, this is because i already have a counter for the id's to make use of later in the program. This is a brief example of how i will use this part.

<div class='row-{$row_pos}'> random data <div>

This gives me odd and even classes on each row so i can use the correct class and stripe my printed results down the page.

The full example of what i use note the id has the counter applied to it and the class has my odd/even result applied to it.:

$i=0;
foreach ($a as $k => $v) {

    $row_pos = ($i & 1) ? 'odd' : 'even';
    echo "<div id='A{$i}' class='row-{$row_pos}'>{$v['f_name']} {$v['l_name']} - {$v['amount']} - {$v['date']}</div>\n";

$i++;
}

in summary, this gives me a very simple way to create a pretty table.

1 Close Android Studio (AS)

2 Delete the folder in C:\Users.gradle\wrapper\dists\gradle-2.1-all

3 Run AS as admin

4 Sync your project files

Although adding something to nodejs module is possible, it seems to be not the best way (if you try to run your code on other computer, the program will crash with the same error, obviously).

I would rather set max listeners number in your own code:

var options = {uri:headingUri, headers:headerData, maxRedirects:100};
request.setMaxListeners(0);
request.get(options, function (error, response, body) {
}

Seems like when I had this problem, it was unique.

Once I removed the package declaration at the top of the file, it worked perfectly.

Aside from doing that, there didn't seem to be any way to run a simple HelloWorld.java on my machine, regardless of the folder the compilation happened in, the CLASSPATH or PATH, parameters or folder called from.

Open terminal and run the following:

curl https://api.codetabs.com/v1/loc?github=username/reponame

No, it will not affect your original repository, just make sure that the repo address looks like "youGitName/TheRepository" and not like "OtherPersonGitName/TheRepo".

I'm consciously writing this answer to an old question with this in mind, because the other answers didn't help me.

I got the Illegal Instruction: 4 while running the binary on the same system I had compiled it on, so -mmacosx-version-min didn't help.

I was using gcc in Code Blocks 16 on Mac OS X 10.11.

However, turning off all of Code Blocks' compiler flags for optimization worked. So look at all the flags Code Blocks set (right-click on the Project -> "Build Properties") and turn off all the flags you are sure you don't need, especially -s and the -Oflags for optimization. That did it for me.

If you're using <table class="table"> on your table, Bootstrap's table class adds a width of 100% to the table. You need to change the width to auto.

Also, if the first row of your table is a header row, you might need to add the width to th rather than td.

For linux users, you should know the following:

1. $CLASSPATH is specifically what Java uses to look through multiple directories to find all the different classes it needs for your script (unless you explicitly tell it otherwise with the -cp override). Using -cp (--classpath) requires that you keep track of all the directories manually and copy-paste that line every time you run the program (not preferable IMO).

2. The colon (":") character separates the different directories. There is only one $CLASSPATH and it has all the directories in it. So, when you run "export CLASSPATH=...." you want to include the current value "$CLASSPATH" in order to append to it. For example:

   export CLASSPATH=.
   export CLASSPATH=$CLASSPATH:/usr/share/java/mysql-connector-java-5.1.12.jar
   

   In the first line above, you start CLASSPATH out with just a simple 'dot' which is the path to your current working directory. With that, whenever you run java it will look in the current working directory (the one you're in) for classes. In the second line above, $CLASSPATH grabs the value that you previously entered (.) and appends the path to a mysql dirver. Now, java will look for the driver AND for your classes.

3. echo $CLASSPATH
   

   is super handy, and what it returns should read like a colon-separated list of all the directories you want java looking in for what it needs to run your script.

4. Tomcat does not use CLASSPATH. Read what to do about that here: https://tomcat.apache.org/tomcat-8.0-doc/class-loader-howto.html

Got a solution that runs. Don't know if it is optimal though. What I do is to split the string according to http://blogs.oracle.com/aramamoo/2010/05/how_to_split_comma_separated_string_and_pass_to_in_clause_of_select_statement.html

Using:
select regexp_substr(' 1, 2 , 3 ','[^,]+', 1, level) from dual
connect by regexp_substr('1 , 2 , 3 ', '[^,]+', 1, level) is not null;

So my final code looks like this ($bp_gr1' are strings like 1,2,3):

Is there a way to make it run faster?

we can use following method QT_Delay:

QTimer::singleShot(2000,this,SLOT(print_lcd()));

This will wait for 2 seconds before calling print_lcd().

Because at least one value is a string the + operator is being interpreted as a string concatenation operator. The simplest fix for this is to indicate that you intend for the values to be interpreted as numbers.

var total = +a + +b;

and

$('#total_price').val(+a + +b);

Or, better, just pull them out as numbers to begin with:

var a = +$('input[name=service_price]').val();
var b = +$('input[name=modem_price]').val();
var total = a+b;
$('#total_price').val(a+b);

See Mozilla's Unary + documentation.

Note that this is only a good idea if you know the value is going to be a number anyway. If this is user input you must be more careful and probably want to use parseInt and other validation as other answers suggest.

Finally!

As of Java 8u191 you now have the options:

-XX:InitialRAMPercentage
-XX:MaxRAMPercentage
-XX:MinRAMPercentage

that can be used to size the heap as a percentage of the usable physical RAM. (which is same as the RAM installed less what the kernel uses).

See Release Notes for Java8 u191 for more information. Note that the options are mentioned under a Docker heading but in fact they apply whether you are in Docker environment or in a traditional environment.

The default value for MaxRAMPercentage is 25%. This is extremely conservative.

My own rule: If your host is more or less dedicated to running the given java application, then you can without problems increase dramatically. If you are on Linux, only running standard daemons and have installed RAM from somewhere around 1 Gb and up then I wouldn't hesitate to use 75% for the JVM's heap. Again, remember that this is 75% of the RAM available, not the RAM installed. What is left is the other user land processes that may be running on the host and the other types of memory that the JVM needs (eg for stack). All together, this will typically fit nicely in the 25% that is left. Obviously, with even more installed RAM the 75% is a safer and safer bet. (I wish the JDK folks had implemented an option where you could specify a ladder)

Setting the MaxRAMPercentage option look like this:

java -XX:MaxRAMPercentage=75.0  ....

Note that these percentage values are of 'double' type and therefore you must specify them with a decimal dot. You get a somewhat odd error if you use "75" instead of "75.0".

{
    return (end.Year - start.Year - 1) +
        (((end.Month > start.Month) ||
        ((end.Month == start.Month) && (end.Day >= start.Day))) ? 1 : 0);

case_when is now a pretty clean implementation of the SQL-style case when:

structure(list(a = c(1, 3, 4, 6, 3, 2, 5, 1), b = c(1, 3, 4, 
2, 6, 7, 2, 6), c = c(6, 3, 6, 5, 3, 6, 5, 3), d = c(6, 2, 4, 
5, 3, 7, 2, 6), e = c(1, 2, 4, 5, 6, 7, 6, 3), f = c(2, 3, 4, 
2, 2, 7, 5, 2)), .Names = c("a", "b", "c", "d", "e", "f"), row.names = c(NA, 
8L), class = "data.frame") -> df


df %>% 
    mutate( g = case_when(
                a == 2 | a == 5 | a == 7 | (a == 1 & b == 4 )     ~   2,
                a == 0 | a == 1 | a == 4 |  a == 3 | c == 4       ~   3
))

Using dplyr 0.7.4

The manual: http://dplyr.tidyverse.org/reference/case_when.html

The Python documentation does explain it.

Tuples and lists are compared lexicographically using comparison of corresponding elements. This means that to compare equal, each element must compare equal and the two sequences must be of the same type and have the same length.

There's more to it than this, but you're probably looking for this list:

B   business day frequency
C   custom business day frequency (experimental)
D   calendar day frequency
W   weekly frequency
M   month end frequency
BM  business month end frequency
MS  month start frequency
BMS business month start frequency
Q   quarter end frequency
BQ  business quarter endfrequency
QS  quarter start frequency
BQS business quarter start frequency
A   year end frequency
BA  business year end frequency
AS  year start frequency
BAS business year start frequency
H   hourly frequency
T   minutely frequency
S   secondly frequency
L   milliseconds
U   microseconds

You can use the string format operator %, similar to sprintf.

mystring = "%.2f" % 5.5999

A little variation with a more compact lookup table and using C++17 features:

std::string base64_decode(const std::string_view in) {
  // table from '+' to 'z'
  const uint8_t lookup[] = {
      62,  255, 62,  255, 63,  52,  53, 54, 55, 56, 57, 58, 59, 60, 61, 255,
      255, 0,   255, 255, 255, 255, 0,  1,  2,  3,  4,  5,  6,  7,  8,  9,
      10,  11,  12,  13,  14,  15,  16, 17, 18, 19, 20, 21, 22, 23, 24, 25,
      255, 255, 255, 255, 63,  255, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35,
      36,  37,  38,  39,  40,  41,  42, 43, 44, 45, 46, 47, 48, 49, 50, 51};
  static_assert(sizeof(lookup) == 'z' - '+' + 1);

  std::string out;
  int val = 0, valb = -8;
  for (uint8_t c : in) {
    if (c < '+' || c > 'z')
      break;
    c -= '+';
    if (lookup[c] >= 64)
      break;
    val = (val << 6) + lookup[c];
    valb += 6;
    if (valb >= 0) {
      out.push_back(char((val >> valb) & 0xFF));
      valb -= 8;
    }
  }
  return out;
}

If you don't have std::string_view, try instead std::experimental::string_view.

As I'm beginner for vba, I'm willing to get a deep knowledge of vba of how all excel in-built functions work form there back.

So as on the above question I have putted my basic efforts.

Function multi_add(a As Range, ParamArray b() As Variant) As Double

    Dim ele As Variant

    Dim i As Long

    For Each ele In a
        multi_add = a + ele.Value **- a**
    Next ele

    For i = LBound(b) To UBound(b)
        For Each ele In b(i)
            multi_add = multi_add + ele.Value
        Next ele
    Next i

End Function

- a: This is subtracted for above code cause a count doubles itself so what values you adds it will add first value twice.

Using type="file" and accept="image/*" (or the format you want), allow the user to chose a file with specific format. But you have to re check it again in client side, because the user can select other type of files. This works for me.

<input #imageInput accept="image/*" (change)="processFile(imageInput)" name="upload-photo" type="file" id="upload-photo" />

And then, in your javascript script

processFile(imageInput) {
    if (imageInput.files[0]) {
      const file: File = imageInput.files[0];
      var pattern = /image-*/;

      if (!file.type.match(pattern)) {
        alert('Invalid format');
        return;
      }

      // here you can do whatever you want with your image. Now you are sure that it is an image
    }
  }

You can use SwiftGif from this link

Usage:

imageView.loadGif(name: "jeremy")

Its not mentioned on doc, but Left sidebar on Bootstrap 3 is possible using "Collapse" method.

As mentioned by bootstrap.js :

Collapse.prototype.dimension = function () {
    var hasWidth = this.$element.hasClass('width')
    return hasWidth ? 'width' : 'height'
  }

This mean, adding class "width" into target, will expand by width instead of height :

http://jsfiddle.net/2316sfbz/2/

There is a hasClass function

if($('#popup p').hasClass('filled-text'))

Just change ACTION_MOVE_EVENT in Chirag Raval Answer to set ZOOM_IN LIMIT

float[] values = new float[9]; matrix.getValues(values);
                //0.37047964 is limit for zoom in
                if(values[Matrix.MSCALE_X]>0.37047964) {
                    matrix.set(savedMatrix);
                    matrix.postScale(scale, scale, mid.x, mid.y);
                    view.setImageMatrix(matrix);
                }else if (scale>1){
                    matrix.set(savedMatrix);
                    matrix.postScale(scale, scale, mid.x, mid.y);
                    view.setImageMatrix(matrix);
                }

If you want to make multiple operation use

select (sel1.s1+sel2+s2)

(select sum(hours) s1 from resource) sel1
join 
(select sum(hours) s2 from projects-time)sel2
on sel1.s1=sel2.s2

Oracle has two different ways of making views updatable:-

1. The view is "key preserved" with respect to what you are trying to update. This means the primary key of the underlying table is in the view and the row appears only once in the view. This means Oracle can figure out exactly which underlying table row to update OR
2. You write an instead of trigger.

I would stay away from instead-of triggers and get your code to update the underlying tables directly rather than through the view.

I had the same problem, but none of the solutions worked for me, because the message The system cannot find the file specified can be misleading in some special cases.

In my case, I use Notepad++ in combination with the registry redirect for notepad.exe. Unfortunately my path to Notepad++ in the registry was wrong.

So in fact the message The system cannot find the file specified was telling me, that it cannot find the application (Notepad++) associated with the file type(*.txt), not the file itself.

As per MSDN the default value is 4096 KB (4 MB).

UPDATE

As for the Maximum, since it is an int data type, then theoretically you can go up to 2,147,483,647. Also I wanted to make sure that you are aware that IIS 7 uses maxAllowedContentLength for specifying file upload size. By default it is set to 30000000 around 30MB and being an uint, it should theoretically allow a max of 4,294,967,295

I spent 3 months working on a solution to the 10 best point dense 5x5 Boggle boards problem.

The problem is now solved and laid out with full disclosure on 5 web pages. Please contact me with questions.

The board analysis algorithm uses an explicit stack to pseudo-recursively traverse the board squares through a Directed Acyclic Word Graph with direct child information, and a time stamp tracking mechanism. This may very well be the world's most advanced lexicon data structure.

The scheme evaluates some 10,000 very good boards per second on a quad core. (9500+ points)

You should bring your data into long (i.e. molten) format to use it with ggplot2:

library("reshape2")
mdf <- melt(mdf, id.vars="Company", value.name="value", variable.name="Year")

And then you have to use aes( ... , group = Company ) to group them:

ggplot(data=mdf, aes(x=Year, y=value, group = Company, colour = Company)) +
    geom_line() +
    geom_point( size=4, shape=21, fill="white")

The id should be placed inside of componentWillMount (update for 2018) constructor, not render. Putting it in render will re-generate new ids unnecessarily.

If you're using underscore or lodash, there is a uniqueId function, so your resulting code should be something like:

constructor(props) {
    super(props);
    this.id = _.uniqueId("prefix-");
}

render() { 
  const id = this.id;
  return (
    <div>
        <input id={id} type="checkbox" />
        <label htmlFor={id}>label</label>
    </div>
  );
}

2019 Hooks update:

import React, { useState } from 'react';
import _uniqueId from 'lodash/uniqueId';

const MyComponent = (props) => {
  // id will be set once when the component initially renders, but never again
  // (unless you assigned and called the second argument of the tuple)
  const [id] = useState(_uniqueId('prefix-'));
  return (
    <div>
      <input id={id} type="checkbox" />
      <label htmlFor={id}>label</label>
    </div>
  );
}

The general rule is that popup blockers will engage if window.open or similar is invoked from javascript that is not invoked by direct user action. That is, you can call window.open in response to a button click without getting hit by the popup blocker, but if you put the same code in a timer event it will be blocked. Depth of call chain is also a factor - some older browsers only look at the immediate caller, newer browsers can backtrack a little to see if the caller's caller was a mouse click etc. Keep it as shallow as you can to avoid the popup blockers.

Ideas from a twisted mind :

class mytwistedclass{
static std::vector<int> initVector;
mytwistedclass()
{
    //initialise with initVector[0] and then delete it :-)
}

};

now set this initVector to something u want to before u instantiate an object. Then your objects are initialized with your parameters.

As @Astariul said, path to the file might cause this bug.
In addition, any parent directory which contains non-ASCII character, for example Chinese, will cause this.
In that case, you should rename you parent directory

You can install and accept the license of the SDK & tools via 2 ways:

1. Open the Android SDK Manager GUI via command line

Open the Android SDK manager via the command line using:

# Android SDK Tools 25.2.3 and lower - Open the Android SDK GUI via the command line
cd ~/Library/Android/sdk/tools && ./android

# 'Android SDK Tools' 25.2.3 and higher - `sdkmanager` is located in android_sdk/tools/bin/.
cd ~/Library/Android/sdk/tools/bin && ./sdkmanager

View more details on the new sdkmanager.

Select and install the required tools. (your location may be different)

2. Install and accept android license via command line:

Update the packages via command line, you'll be presented with the terms and conditions which you'll need to accept.

- Install or update to the latest version

This will install the latest platform-tools at the time you run it.

# Android SDK Tools 25.2.3 and lower. Install the latest `platform-tools` for android-25
android update sdk --no-ui --all --filter platform-tools,android-25,extra-android-m2repository

# Android SDK Tools 25.2.3 and higher
sdkmanager --update

- Install a specific version (25.0.1, 24.0.1, 23.0.1)

You can also install a specific version like so:

# Build Tools 23.0.1, 24.0.1, 25.0.1
android update sdk --no-ui --all --filter build-tools-25.0.1,android-25,extra-android-m2repository
android update sdk --no-ui --all --filter build-tools-24.0.1,android-24,extra-android-m2repository
android update sdk --no-ui --all --filter build-tools-23.0.1,android-23,extra-android-m2repository

I wouldn't say that structs offer less functionality.

Sure, self is immutable except in a mutating function, but that's about it.

Inheritance works fine as long as you stick to the good old idea that every class should be either abstract or final.

Implement abstract classes as protocols and final classes as structs.

The nice thing about structs is that you can make your fields mutable without creating shared mutable state because copy on write takes care of that :)

That's why the properties / fields in the following example are all mutable, which I would not do in Java or C# or swift classes.

Example inheritance structure with a bit of dirty and straightforward usage at the bottom in the function named "example":

protocol EventVisitor
{
    func visit(event: TimeEvent)
    func visit(event: StatusEvent)
}

protocol Event
{
    var ts: Int64 { get set }

    func accept(visitor: EventVisitor)
}

struct TimeEvent : Event
{
    var ts: Int64
    var time: Int64

    func accept(visitor: EventVisitor)
    {
        visitor.visit(self)
    }
}

protocol StatusEventVisitor
{
    func visit(event: StatusLostStatusEvent)
    func visit(event: StatusChangedStatusEvent)
}

protocol StatusEvent : Event
{
    var deviceId: Int64 { get set }

    func accept(visitor: StatusEventVisitor)
}

struct StatusLostStatusEvent : StatusEvent
{
    var ts: Int64
    var deviceId: Int64
    var reason: String

    func accept(visitor: EventVisitor)
    {
        visitor.visit(self)
    }

    func accept(visitor: StatusEventVisitor)
    {
        visitor.visit(self)
    }
}

struct StatusChangedStatusEvent : StatusEvent
{
    var ts: Int64
    var deviceId: Int64
    var newStatus: UInt32
    var oldStatus: UInt32

    func accept(visitor: EventVisitor)
    {
        visitor.visit(self)
    }

    func accept(visitor: StatusEventVisitor)
    {
        visitor.visit(self)
    }
}

func readEvent(fd: Int) -> Event
{
    return TimeEvent(ts: 123, time: 56789)
}

func example()
{
    class Visitor : EventVisitor
    {
        var status: UInt32 = 3;

        func visit(event: TimeEvent)
        {
            print("A time event: \(event)")
        }

        func visit(event: StatusEvent)
        {
            print("A status event: \(event)")

            if let change = event as? StatusChangedStatusEvent
            {
                status = change.newStatus
            }
        }
    }

    let visitor = Visitor()

    readEvent(1).accept(visitor)

    print("status: \(visitor.status)")
}

You can also do it like:

str = str.replace(/\s/g, "+");

Have a look at this fiddle.

Alternatively, you can use Inner Queries to do so.

SQL> INSERT INTO <NEW_TABLE> SELECT * FROM CUSTOMERS WHERE ID IN (SELECT ID FROM <OLD_TABLE>);

Hope this helps!

If someone is looking for a one-liner which calculates the actual overlap:

int overlap = ( x2 > y1 || y2 < x1 ) ? 0 : (y2 >= y1 && x2 <= y1 ? y1 : y2) - ( x2 <= x1 && y2 >= x1 ? x1 : x2) + 1; //max 11 operations

If you want a couple fewer operations, but a couple more variables:

bool b1 = x2 <= y1;
bool b2 = y2 >= x1;
int overlap = ( !b1 || !b2 ) ? 0 : (y2 >= y1 && b1 ? y1 : y2) - ( x2 <= x1 && b2 ? x1 : x2) + 1; // max 9 operations

If that is the case, I think you need to use a better way of creating a class name or a class name convention. For example, like you said you want the .container class to have different color according to a specific usage or appearance. You can do this:

SCSS

.container {
  background: red;

  &--desc {
    background: blue;
  }

  // or you can do a more specific name
  &--blue {
    background: blue;
  }

  &--red {
    background: red;
  }
}

CSS

.container {
  background: red;
}

.container--desc {
  background: blue;
}

.container--blue {
  background: blue;
}

.container--red {
  background: red;
}

The code above is based on BEM Methodology in class naming conventions. You can check this link: BEM — Block Element Modifier Methodology

Pass Data using NSNotificationCenter

You can also pass data using NotificationCentre in swift 3.0 and NSNotificationCenter in swift 2.0.

Swift 2.0 Version

Pass info using userInfo which is a optional Dictionary of type [NSObject : AnyObject]?

let imageDataDict:[String: UIImage] = ["image": image]

// Post a notification
 NSNotificationCenter.defaultCenter().postNotificationName(notificationName, object: nil, userInfo: imageDataDict)

// Register to receive notification in your class
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(self.showSpinningWheel(_:)), name: notificationName, object: nil)

// handle notification
func showSpinningWheel(notification: NSNotification) {
  if let image = notification.userInfo?["image"] as? UIImage {
  // do something with your image   
  }
}

Swift 3.0 Version

The userInfo now takes [AnyHashable:Any]? as an argument, which we provide as a dictionary literal in Swift

let imageDataDict:[String: UIImage] = ["image": image]

// post a notification
 NotificationCenter.default.post(name: NSNotification.Name(rawValue: "notificationName"), object: nil, userInfo: imageDataDict) 
// `default` is now a property, not a method call

// Register to receive notification in your class
NotificationCenter.default.addObserver(self, selector: #selector(self.showSpinningWheel(_:)), name: NSNotification.Name(rawValue: "notificationName"), object: nil)

// handle notification
func showSpinningWheel(_ notification: NSNotification) {

  if let image = notification.userInfo?["image"] as? UIImage {
  // do something with your image   
  }
}

Source pass data using NotificationCentre(swift 3.0) and NSNotificationCenter(swift 2.0)

You don't need CSS for this.

     <img src="abc"/>

now with link:

     <a href="#myLink"><img src="abc"/></a>

Or with jquery, later on, you can use the wrap property, see these questions answer:

how to add a link to an image using jquery?

I wrote an article on topis how to [manually install curl on debian linu][1]x.

[1]: http://www.jasom.net/how-to-install-curl-command-manually-on-debian-linux. This is its shortcut:

1. cd /usr/local/src
2. wget http://curl.haxx.se/download/curl-7.36.0.tar.gz
3. tar -xvzf curl-7.36.0.tar.gz
4. rm *.gz
5. cd curl-7.6.0
6. ./configure
7. make
8. make install

And restart Apache. If you will have an error during point 6, try to run apt-get install build-essential.

curl is a command in linux (and a library in php). Curl typically makes an HTTP request.

What you really want to do is make an HTTP (or XHR) request from javascript.

Using this vocab you'll find a bunch of examples, for starters: Sending authorization headers with jquery and ajax

Essentially you will want to call $.ajax with a few options for the header, etc.

$.ajax({
        url: 'https://api.wit.ai/message?v=20140826&q=',
        beforeSend: function(xhr) {
             xhr.setRequestHeader("Authorization", "Bearer 6QXNMEMFHNY4FJ5ELNFMP5KRW52WFXN5")
        }, success: function(data){
            alert(data);
            //process the JSON data etc
        }
})

I wrote an article about finding the bounding coordinates:

http://JanMatuschek.de/LatitudeLongitudeBoundingCoordinates

The article explains the formulae and also provides a Java implementation. (It also shows why Federico's formula for the min/max longitude is inaccurate.)

you must changes in $watch ....

function MyController($scope) {_x000D_
    $scope.form = {_x000D_
        name: 'my name',_x000D_
    }_x000D_
_x000D_
    $scope.$watch('form.name', function(newVal, oldVal){_x000D_
        console.log('changed');_x000D_
     _x000D_
    });_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.22/angular.min.js"></script>_x000D_
<div ng-app>_x000D_
    <div ng-controller="MyController">_x000D_
        <label>Name:</label> <input type="text" ng-model="form.name"/>_x000D_
            _x000D_
        <pre>_x000D_
            {{ form }}_x000D_
        </pre>_x000D_
    </div>_x000D_
</div>

Using some of the knowledge from this and a couple of other posts, I found the method that worked the best for me was to:

adb shell 'stty raw; screencap -p'

I have posted a very simple Python script on GitHub that essentially mirrors the screen of a device connected over ADB:

https://github.com/baitisj/android_screen_mirror

Demo : http://jsfiddle.net/NbGBj/

$("document").ready(function(){

    $("#upload").change(function() {
        alert('changed!');
    });
});

As Wagner Francisco said, (in JADE)

input(type="text", ng-model="someModel", placeholder="{{someScopeVariable}}")`

And in your controller :

$scope.someScopeVariable = 'somevalue'

To reset text, number, search, textarea inputs:

$('#shares').val('');

To reset select:

$('#select-box').prop('selectedIndex',0);

To reset radio input:

$('#radio-input').attr('checked',false);

To reset file input:

$("#file-input").val(null);

The following works for me:

git push -f origin branch_name

and it does not remove any of my code.

But, if you want to avoid this then you can do the following:

git checkout master
git pull --rebase
git checkout -b new_branch_name

then you can cherry-pick all your commits to the new branch. git cherry-pick COMMIT ID and then push your new branch.

if(isAllChecked == 0)
{ 
    $("#select_all").prop("checked", true); 
}   

please change the above line to

if(isAllChecked == 0)
{ 
    $("#checkedAll").prop("checked", true); 
}   

in SSR's answer and its working perfect Thank you

Other bash alternatives that do not involve a subshell:

read str <<END             # here-doc
hello
END

read str <<< "hello"       # here-string

read str < <(echo hello)   # process substitution

You can use localStorage to save the data for later use, but you can not save to a file using JavaScript (in the browser).

To be comprehensive: You can not store something into a file using JavaScript in the Browser, but using HTML5, you can read files.

iframe have "sandbox" attribute that may block pop up etc

Tangential: String.format() rocks:

public String toString() {
    return String.format("%s %s", getMake(), getReg());
}

private static void printAll() {
    for (Car car: cars)
        System.out.println(car); // invokes Car.toString()
}

Global libraries

You can run npm list -g to see which global libraries are installed and where they're located. Use npm list -g | head -1 for truncated output showing just the path. If you want to display only main packages not its sub-packages which installs along with it - you can use - npm list --depth=0 which will show all packages and for getting only globally installed packages, just add -g i.e. npm list -g --depth=0.

On Unix systems they are normally placed in /usr/local/lib/node or /usr/local/lib/node_modules when installed globally. If you set the NODE_PATH environment variable to this path, the modules can be found by node.

Windows XP - %USERPROFILE%\AppData\npm\node_modules
Windows 7, 8 and 10 - %USERPROFILE%\AppData\Roaming\npm\node_modules

Non-global libraries

Non-global libraries are installed the node_modules sub folder in the folder you are currently in.

You can run npm list to see the installed non-global libraries for your current location.

When installing use -g option to install globally

npm install -g pm2 - pm2 will be installed globally. It will then typically be found in /usr/local/lib/node_modules (Use npm root -g to check where.)

npm install pm2 - pm2 will be installed locally. It will then typically be found in the local directory in /node_modules

Unlike stated previously 'preceding-sibling' is really the axis to use, not 'preceding' which does something completely different, it selects everything in the document that is before the start tag of the current node. (see http://www.w3schools.com/xpath/xpath_axes.asp)

A little late but I believe some further clarification is given below.

You can iterate through a JSON array with a simple loop as well, like:

for(var i = 0; i < jsonArray.length; i++)
{
    console.log(jsonArray[i].attributename);
}

If you have a JSON object and you want to loop through all of its inner objects, then you first need to get all the keys in an array and loop through the keys to retrieve objects using the key names, like:

var keys = Object.keys(jsonObject);
for(var i = 0; i < keys.length; i++) 
{
    var key = keys[i];
    console.log(jsonObject.key.attributename);
}

TRUNCATE TABLE is functionally identical to DELETE statement with no WHERE clause: both remove all rows in the table. But TRUNCATE TABLE is faster and uses fewer system and transaction log resources than DELETE.

The DELETE statement removes rows one at a time and records an entry in the transaction log for each deleted row. TRUNCATE TABLE removes the data by deallocating the data pages used to store the table's data, and only the page deallocations are recorded in the transaction log.

TRUNCATE TABLE removes all rows from a table, but the table structure and its columns, constraints, indexes and so on remain. The counter used by an identity for new rows is reset to the seed for the column. If you want to retain the identity counter, use DELETE instead. If you want to remove table definition and its data, use the DROP TABLE statement.

You cannot use TRUNCATE TABLE on a table referenced by a FOREIGN KEY constraint; instead, use DELETE statement without a WHERE clause. Because TRUNCATE TABLE is not logged, it cannot activate a trigger.

TRUNCATE TABLE may not be used on tables participating in an indexed view.

Bizarrely if I remove the proxy from the environment and add it to the command line it works for me. For example to upgrade pip itself:

env http_proxy= https_proxy= pip install pip --upgrade --proxy 'http://proxy-url:80'

My issue was having the proxy in the environment. It seems that pip only honors the one in argument.

Thanks to tosh shimayama for his solution.
I thought it was not so clean to put a service straight into the $scope, so here's my slight variation on that: http://plnkr.co/edit/QJbuZZnZEDOBcYrJXWWs

The controller (that in original answer seemed to me a little bit too dumb) creates an ActionBar object, and this one is stuffed into $scope.
The object is responsible for actually querying the service. It also hides from the $scope the call to set the template URL, which instead is available to other controllers to set the URL.

your first try is using declarative pipelines, and the second working one is using scripted pipelines. you need to enclose steps in a steps declaration, and you can't use if as a top-level step in declarative, so you need to wrap it in a script step. here's a working declarative version:

pipeline {
    agent any

    stages {
        stage('test') {
            steps {
                sh 'echo hello'
            }
        }
        stage('test1') {
            steps {
                sh 'echo $TEST'
            }
        }
        stage('test3') {
            steps {
                script {
                    if (env.BRANCH_NAME == 'master') {
                        echo 'I only execute on the master branch'
                    } else {
                        echo 'I execute elsewhere'
                    }
                }
            }
        }
    }
}

you can simplify this and potentially avoid the if statement (as long as you don't need the else) by using "when". See "when directive" at https://jenkins.io/doc/book/pipeline/syntax/. you can also validate jenkinsfiles using the jenkins rest api. it's super sweet. have fun with declarative pipelines in jenkins!

df.loc[:,df.columns.str.contains("spike")]

I've created my own formatting utility. Which is extremely fast at processing the formatting along with giving you many features :)

It supports:

• Comma Formatting E.g. 1234567 becomes 1,234,567.
• Prefixing with "Thousand(K),Million(M),Billion(B),Trillion(T)".
• Precision of 0 through 15.
• Precision re-sizing (Means if you want 6 digit precision, but only have 3 available digits it forces it to 3).
• Prefix lowering (Means if the prefix you choose is too large it lowers it to a more suitable prefix).

The code can be found here. You call it like this:

public static void main(String[])
{
   int settings = ValueFormat.COMMAS | ValueFormat.PRECISION(2) | ValueFormat.MILLIONS;
   String formatted = ValueFormat.format(1234567, settings);
}

I should also point out this doesn't handle decimal support, but is very useful for integer values. The above example would show "1.23M" as the output. I could probably add decimal support maybe, but didn't see too much use for it since then I might as well merge this into a BigInteger type of class that handles compressed char[] arrays for math computations.

For a GUI approach I would take a look at Activity Monitor under Management and sort by CPU.

What you have to do is to append the values as parameters in the iframe src (URL).

E.g. <iframe src="some_page.php?somedata=5&more=bacon"></iframe>

And then in some_page.php file you use php $_GET['somedata'] to retrieve it from the iframe URL. NB: Iframes run as a separate browser window in your file.

Just to improve YCR's answer:

1) I added black lines on x and y axis. Otherwise they are made transparent too.

2) I added a transparent theme to the legend key. Otherwise, you will get a fill there, which won't be very esthetic.

Finally, note that all those work only with pdf and png formats. jpeg fails to produce transparent graphs.

MyTheme_transparent <- theme(
    panel.background = element_rect(fill = "transparent"), # bg of the panel
    plot.background = element_rect(fill = "transparent", color = NA), # bg of the plot
    panel.grid.major = element_blank(), # get rid of major grid
    panel.grid.minor = element_blank(), # get rid of minor grid
    legend.background = element_rect(fill = "transparent"), # get rid of legend bg
    legend.box.background = element_rect(fill = "transparent"), # get rid of legend panel bg
    legend.key = element_rect(fill = "transparent", colour = NA), # get rid of key legend fill, and of the surrounding
    axis.line = element_line(colour = "black") # adding a black line for x and y axis
)

Block

Takes up the full width available, with a new line before and after (display:block;)

Inline

Takes up only as much width as it needs, and does not force new lines (display:inline;)

The grammar of the language specifies that positional arguments appear before keyword or starred arguments in calls:

argument_list        ::=  positional_arguments ["," starred_and_keywords]
                            ["," keywords_arguments]
                          | starred_and_keywords ["," keywords_arguments]
                          | keywords_arguments

Specifically, a keyword argument looks like this: tag='insider trading!' while a positional argument looks like this: ..., exchange, .... The problem lies in that you appear to have copy/pasted the parameter list, and left some of the default values in place, which makes them look like keyword arguments rather than positional ones. This is fine, except that you then go back to using positional arguments, which is a syntax error.

Also, when an argument has a default value, such as price=None, that means you don't have to provide it. If you don't provide it, it will use the default value instead.

To resolve this error, convert your later positional arguments into keyword arguments, or, if they have default values and you don't need to use them, simply don't specify them at all:

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity)

# Fully positional:
order_id = kite.order_place(self, exchange, tradingsymbol, transaction_type, quantity, price, product, order_type, validity, disclosed_quantity, trigger_price, squareoff_value, stoploss_value, trailing_stoploss, variety, tag)

# Some positional, some keyword (all keywords at end):

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity, tag='insider trading!')

Change that import to

from matplotlib.pyplot import *

Note that this style of imports (from X import *) is generally discouraged. I would recommend using the following instead:

import matplotlib.pyplot as plt
plt.plot([1,2,3,4])

With pure html (no JS), you can't really substitute a radio-button for an image (at least, I don't think you can). You could, though use the following to make the same connection to the user:

<form action="" method="post">
    <fieldset>
       <input type="radio" name="feeling" id="feelingSad" value="sad" /><label for="feelingSad"><img src="path/to/sad.png" /></label>
       <label for="feelingHappy"><input type="radio" name="feeling" id="feelingHappy" value="happy" /><img src="path/to/happy.png" /></label>
    </fieldset>
</form>

you can also use append function

b = [ ]

for x in range(0, 5):
    b.append(["O"] * 5)

def print_b(b):
    for row in b:
        print " ".join(row)

To reduce the required packages to install you just need

apt-get install -y \

dialog = new Dialog(getActivity(),android.R.style.Theme_Translucent_NoTitleBar);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(R.layout.loading_screen);
    Window window = dialog.getWindow();
    WindowManager.LayoutParams wlp = window.getAttributes();

    wlp.gravity = Gravity.CENTER;
    wlp.flags &= ~WindowManager.LayoutParams.FLAG_BLUR_BEHIND;
    window.setAttributes(wlp);
    dialog.getWindow().setLayout(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
    dialog.show();

try this.

I know the solution employing printing of new lines isn't much supported, but if all else fails, why not? Especially where one is operating in an environment where someone else is likely to be able to see the screen, yet not able to keylog. One potential solution then, is the following alias:

alias c="printf '\r\n%.0s' {1..50}"

Then, to "clear" away the current contents of the screen (or rather, hide them), just type c+Enter at the terminal.

In some cases median gets calculated as follows :

The "median" is the "middle" value in the list of numbers when they are ordered by value. For even count sets, median is average of the two middle values. I've created a simple code for that :

$midValue = 0;
$rowCount = "SELECT count(*) as count {$from} {$where}";

$even = FALSE;
$offset = 1;
$medianRow = floor($rowCount / 2);
if ($rowCount % 2 == 0 && !empty($medianRow)) {
  $even = TRUE;
  $offset++;
  $medianRow--;
}

$medianValue = "SELECT column as median 
               {$fromClause} {$whereClause} 
               ORDER BY median 
               LIMIT {$medianRow},{$offset}";

$medianValDAO = db_query($medianValue);
while ($medianValDAO->fetch()) {
  if ($even) {
    $midValue = $midValue + $medianValDAO->median;
  }
  else {
    $median = $medianValDAO->median;
  }
}
if ($even) {
  $median = $midValue / 2;
}
return $median;

The $median returned would be the required result :-)

Functions from .py file (can (of course) be in different directory) can be simply imported by writing directories first and then the file name without .py extension:

from directory_name.file_name import function_name

And later be used: function_name()

Update 2019

In Bootstrap 4, flexbox can be used to get a full height layout that fills the remaining space.

First of all, the container (parent) needs to be full height:

Option 1_ Add a class for min-height: 100%;. Remember that min-height will only work if the parent has a defined height:

html, body {
  height: 100%;
}

.min-100 {
    min-height: 100%;
}

https://codeply.com/go/dTaVyMah1U

Option 2_ Use vh units:

.vh-100 {
    min-height: 100vh;
}

https://codeply.com/go/kMahVdZyGj

Also of Bootstrap 4.1, the vh-100 and min-vh-100 classes are included in Bootstrap so there is no need to for the extra CSS

Then, use flexbox direction column d-flex flex-column on the container, and flex-grow-1 on any child divs (ie: row) that you want to fill the remaining height.

Addition:

When using the MySQL client library, then you should prevent a conversion back to your connection's default charset. (see mysql_set_character_set()[1])

In this case, use an additional cast to binary:

SELECT column1, CAST(CONVERT(column2 USING utf8) AS binary)
FROM my_table
WHERE my_condition;

Otherwise, the SELECT statement converts to utf-8, but your client library converts it back to a (potentially different) default connection charset.

You can use IntArrays.quickSort(array, comparator) from fastutil library.

Well, you could do something like this using Java 8's time-API, for this problem specifically java.time.LocalDate (or the equivalent Joda Time classes for Java 7 and older)

for (LocalDate date = startDate; date.isBefore(endDate); date = date.plusDays(1))
{
    ...
}

I would thoroughly recommend using java.time (or Joda Time) over the built-in Date/Calendar classes.

My guess is that you're trying to squeeze a number greater than 99999.99 into your decimal fields. Changing it to (8,3) isn't going to do anything if it's greater than 99999.999 - you need to increase the number of digits before the decimal. You can do this by increasing the precision (which is the total number of digits before and after the decimal). You can leave the scale the same unless you need to alter how many decimal places to store. Try decimal(9,2) or decimal(10,2) or whatever.

You can test this by commenting out the insert #temp and see what numbers the select statement is giving you and see if they are bigger than your column can handle.

By executing the following command, it will save a jenkins-ci.org.key file in the current working directory:

curl -O http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key

Then use the following command to add the key file:

apt-key add jenkins-ci.org.key

If the system returns OK, then the key file has been successfully added.

For the basic (the current week's Sunday)

select cast(dateadd(day,-(datepart(dw,getdate())-1),getdate()) as date)

If previous week:

select cast(dateadd(day,-(datepart(dw,getdate())-1),getdate()) -7 as date)

Internally, we built a function that does it but if you need quick and dirty, this will do it.

It may not be quite what you want, since it's not a standard command on anyone's systems, but since my program should work fine on POSIX systems (if compiled), I'll mention it anyway. If you have the ability to compile or add programs on the machine in question, it should work.

I've used it without issue for about a year now, but it could be that it won't handle some edge cases. Most specifically, I have no idea what it would do with newlines in strings; a case for \\n might need to be added. This list of characters is not authoritative, but I believe it covers everything else.

I wrote this specifically as a 'helper' program so I could make a wrapper for things like scp commands.

It can likely be implemented as a shell function as well

I therefore present escapify.c. I use it like so:

scp user@host:"$(escapify "/this/path/needs to be escaped/file.c")" destination_file.c

PLEASE NOTE: I made this program for my own personal use. It also will (probably wrongly) assume that if it is given more than one argument that it should just print an unescaped space and continue on. This means that it can be used to pass multiple escaped arguments correctly, but could be seen as unwanted behavior by some.

#include <string.h>
#include <stdlib.h>
int main(int argc, char **argv)
{
  char c='\0';
  int i=0;
  int j=1;
  /* do not care if no args passed; escaped nothing is still nothing. */
  if(argc < 2)
  {
    return 0;
  }
  while(j<argc)
  {
    while(i<strlen(argv[j]))
    {
      c=argv[j][i];
      /* this switch has no breaks on purpose. */
      switch(c)
      {
      case ';':

        putchar(c);
      }
      i++;
    }
    j++;
    if(j<argc) {
      putchar(' ');
    }
    i=0;
  }
  /* newline at end */

Truth values can be described using a Boolean algebra. The article also contains tables for and and or. This should help you to get started or to get even more confused.

Use SERVER_NAME.

echo $_SERVER['SERVER_NAME']; //Outputs www.example.com

The below code helps me:

 {{ request.build_absolute_uri }}

I found that the accepted answer didn't suffice, since X-FRAME-OPTIONS: Allow-From isn't supported in safari or chrome. Went with a different approach instead, found in a presentation given by Ben Vinegar from Disqus. The idea is to add an event listener to the parent window, and then inside the iframe, use window.postMessage to send an event to the parent telling it to do something (resize the iframe).

So in the parent document, add an event listener:

window.addEventListener('message', function(e) {
  var $iframe = jQuery("#myIframe");
  var eventName = e.data[0];
  var data = e.data[1];
  switch(eventName) {
    case 'setHeight':
      $iframe.height(data);
      break;
  }
}, false);

And inside the iframe, write a function to post the message:

function resize() {
  var height = document.getElementsByTagName("html")[0].scrollHeight;
  window.parent.postMessage(["setHeight", height], "*"); 
}

Finally, inside the iframe, add an onLoad to the body tag to fire the resize function:

<body onLoad="resize();">

I've the same message, I have a webpage with do on visual studio 2010, I read a file.xls on that page,in my project visual has not any problem, when I put it on my IIS local throw me a 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine' ,I fixed that problem next following this steps,

1.-Open IIS
2.-Change the appPool on Advanced Settings
3.-true to enable to 32-bit application.

and that's all

Use json_decode to transform your JSON into a PHP array. Example:

$json = '{"a":"b"}';
$array = json_decode($json, true);
echo $array['a']; // b

I'm not content with HTML/CSS-only solutions, so I've decided to create a custom select using JavaScript.

This is something I've written in the past 30 mins, thus it can be further improved.

All you have to do is create a simple list with few data attributes. The code automatically turns the list into a selectable dropdown. It also adds a hidden input to hold the selected value, so it can be used in a form.

Input:

<ul class="select" data-placeholder="Role" data-name="role">
  <li data-value="admin">Administrator</li>
  <li data-value="mod">Moderator</li>
  <li data-value="user">User</li>
</ul>

Output:

<div class="ul-select-container">
    <input type="hidden" name="role" class="hidden">
    <div class="selected placeholder">
        <span class="text">Role</span>
        <span class="icon">?</span>
    </div>
    <ul class="select" data-placeholder="Role" data-name="role">
        <li class="placeholder">Role</li>
        <li data-value="admin">Administrator</li>
        <li data-value="mod">Moderator</li>
        <li data-value="user">User</li>
    </ul>
</div>

The text of the item that's supposed to be a placeholder is grayed out. The placeholder is selectable, in case the user wants to revert his/her choice. Also using CSS, all the drawbacks of select can be overcome (e.g., inability of the styling of the options).

I've been interested in the original question here and related ones.

For an answer, this week I did some experiments with XCOPY.

To help answer the original question, here I post the results of my experiments.

I did the experiments on Windows 7 64 bit Professional SP1 with the copy of XCOPY that came with the operating system.

For the experiments, I wrote some code in the scripting language Open Object Rexx and the editor macro language Kexx with the text editor KEdit.

XCOPY was called from the Rexx code. The Kexx code edited the screen output of XCOPY to focus on the crucial results.

The experiments all had to do with using XCOPY to copy one directory with several files and subdirectories.

The experiments consisted of 10 cases. Each case adjusted the arguments to XCOPY and called XCOPY once. All 10 cases were attempting to do the same copying operation.

Here are the main results:

(1) Of the 10 cases, only three did copying. The other 7 cases right away, just from processing the arguments to XCOPY, gave error messages, e.g.,

Invalid path

Access denied

with no files copied.

Of the three cases that did copying, they all did the same copying, that is, gave the same results.

(2) If want to copy a directory X and all the files and directories in directory X, in the hierarchical file system tree rooted at directory X, then apparently XCOPY -- and this appears to be much of the original question -- just will NOT do that.

One consequence is that if using XCOPY to copy directory X and its contents, then CAN copy the contents but CANNOT copy the directory X itself; thus, lose the time-date stamp on directory X, its archive bit, data on ownership, attributes, etc.

Of course if directory X is a subdirectory of directory Y, an XCOPY of Y will copy all of the contents of directory Y WITH directory X. So in this way can get a copy of directory X. However, the copy of directory X will have its time-date stamp of the time of the run of XCOPY and NOT the time-date stamp of the original directory X.

This change in time-date stamps can be awkward for a copy of a directory with a lot of downloaded Web pages: The HTML file of the Web page will have its original time-date stamp, but the corresponding subdirectory for files used by the HTML file will have the time-date stamp of the run of XCOPY. So, when sorting the copy on time date stamps, all the subdirectories, the HTML files and the corresponding subdirectories, e.g.,

x.htm

x_files

can appear far apart in the sort on time-date.

Hierarchical file systems go way back, IIRC to Multics at MIT in 1969, and since then lots of people have recognized the two cases, given a directory X, (i) copy directory X and all its contents and (ii) copy all the contents of X but not directory X itself. Well, if only from the experiments, XCOPY does only (ii).

So, the results of the 10 cases are below. For each case, in the results the first three lines have the first three arguments to XCOPY. So, the first line has the tree name of the directory to be copied, the 'source'; the second line has the tree name of the directory to get the copies, the 'destination', and the third line has the options for XCOPY. The remaining 1-2 lines have the results of the run of XCOPY.

One big point about the options is that options /X and /O result in result

Access denied

To see this, compare case 8 with the other cases that were the same, did not have /X and /O, but did copy.

These experiments have me better understand XCOPY and contribute an answer to the original question.

======= case 1 ==================
"k:\software\dir_time-date\"
"k:\software\xcopy002_test\xcopy002_test_dirs\output_sub_dir_1\"
options = /E /F /G /H /K /O /R /V /X /Y
Result:  Invalid path
Result:  0 File(s) copied
======= case 2 ==================

By default session object is available on jsp page(implicit object). It will not available in normal POJO java class. You can get the reference of HttpSession object on Servelt by using HttpServletRequest

HttpSession s=request.getSession()
s.setAttribute("name","value");

You can get session on an ActionSupport based Action POJO class as follows

 ActionContext ctx= ActionContext.getContext();
   Map m=ctx.getSession();
   m.put("name", value);

look at: http://ohmjavaclasses.blogspot.com/2011/12/access-session-in-action-class-struts2.html

if alien.platform == "windows" then
  kernel32 = alien.load("kernel32.dll")
  sleep = kernel32.Sleep
  sleep:types{ret="void",abi="stdcall","uint"}
else
  -- untested !!!
  libc = alien.default

you can add class in anchor tag also like below

.a_class {font-size: 100px} 

As @Ian explained, the problem is that jQuery's click() is not the same as the native one.

Therefore, consider using vanilla-js instead of jQuery:

var a = document.createElement('a');
a.href = "img.png";
a.download = "output.png";
document.body.appendChild(a);
a.click();
document.body.removeChild(a);

Demo

I assume you are getting an exception because of Single. Your list may have more than one answer marked as correct, that is why Single will throw an exception use First, or FirstOrDefault();

Answer answer = Answers.FirstOrDefault(a => a.Correct);

Also if you want to get list of all items marked as correct you may try:

List<Answer> correctedAnswers =  Answers.Where(a => a.Correct).ToList();

If your desired result is Single, then the mistake you are doing in your query is comparing an item with the bool value. Your comparison

a == a.Correct

is wrong in the statement. Your single query should be:

Answer answer = Answers.Single(a => a.Correct == true);

Or shortly as:

Answer answer = Answers.Single(a => a.Correct);

String.Trim() returns a string which equals the input string with all white-spaces trimmed from start and end:

"   A String   ".Trim() -> "A String"

String.TrimStart() returns a string with white-spaces trimmed from the start:

"   A String   ".TrimStart() -> "A String   "

String.TrimEnd() returns a string with white-spaces trimmed from the end:

"   A String   ".TrimEnd() -> "   A String"

None of the methods modify the original string object.

(In some implementations at least, if there are no white-spaces to be trimmed, you get back the same string object you started with:

csharp> string a = "a"; csharp> string trimmed = a.Trim(); csharp> (object) a == (object) trimmed; returns true

I don't know whether this is guaranteed by the language.)

Thanks to unutbu for the explanation. By default numpy.cov calculates the sample covariance. To obtain the population covariance you can specify normalisation by the total N samples like this:

Covariance = numpy.cov(a, b, bias=True)[0][1]
print(Covariance)

or like this:

Covariance = numpy.cov(a, b, ddof=0)[0][1]
print(Covariance)

Make sure your iframe is already loaded. Old but reliable way without jQuery:

<iframe src="samedomain.com/page.htm" id="iframe" onload="access()"></iframe>

<script>
function access() {
   var iframe = document.getElementById("iframe");
   var innerDoc = iframe.contentDocument || iframe.contentWindow.document;
   console.log(innerDoc.body);
}
</script>

There are built-in functions in Python for "right" and "left", if you are looking for a boolean result.

str = "this_is_a_test"
left = str.startswith("this")
print(left)
> True

right = str.endswith("test")
print(right)
> True

I'm not sure if this is 100% portable but the way the OS SHOULD parse the args is to scan through the console command string and insert a nil-term char at the end of each token, and int main(int,char**) doesn't use const char** so we can just iterate through the args starting from the third argument (@note the first arg is the working directory) and scan backward to the nil-term char and turn it into a space rather than start from beginning of the second argument and scanning forward to the nil-term char. Here is the function with test script, and if you do need to un-nil-ify more than one nil-term char then please comment so I can fix it; thanks.

When do you choose functional programming over object oriented?

When you anticipate a different kind of software evolution:

• Object-oriented languages are good when you have a fixed set of operations on things, and as your code evolves, you primarily add new things. This can be accomplished by adding new classes which implement existing methods, and the existing classes are left alone.

• Functional languages are good when you have a fixed set of things, and as your code evolves, you primarily add new operations on existing things. This can be accomplished by adding new functions which compute with existing data types, and the existing functions are left alone.

When evolution goes the wrong way, you have problems:

• Adding a new operation to an object-oriented program may require editing many class definitions to add a new method.

• Adding a new kind of thing to a functional program may require editing many function definitions to add a new case.

This problem has been well known for many years; in 1998, Phil Wadler dubbed it the "expression problem". Although some researchers think that the expression problem can be addressed with such language features as mixins, a widely accepted solution has yet to hit the mainstream.

What are the typical problem definitions where functional programming is a better choice?

Functional languages excel at manipulating symbolic data in tree form. A favorite example is compilers, where source and intermediate languages change seldom (mostly the same things), but compiler writers are always adding new translations and code improvements or optimizations (new operations on things). Compilation and translation more generally are "killer apps" for functional languages.

If by Alt-F4 or X you mean "Exit the Application Immediately Without Regard for What Other Windows or Threads are Running", then System.exit(...) will do exactly what you want in a very abrupt, brute-force, and possibly problematic fashion.

If by Alt-F4 or X you mean hide the window, then frame.setVisible(false) is how you "close" the window. The window will continue to consume resources/memory but can be made visible again very quickly.

If by Alt-F4 or X you mean hide the window and dispose of any resources it is consuming, then frame.dispose() is how you "close" the window. If the frame was the last visible window and there are no other non-daemon threads running, the program will exit. If you show the window again, it will have to reinitialize all of the native resources again (graphics buffer, window handles, etc).

dispose() might be closest to the behavior that you really want. If your app has multiple windows open, do you want Alt-F4 or X to quit the app or just close the active window?

The Java Swing Tutorial on Window Listeners may help clarify things for you.

We can use infowindow.close(map); to close all info windows if you already initialize the info window using infowindow = new google.maps.InfoWindow();

".do" is the "standard" extension mapped to for Struts Java platform. See http://struts.apache.org/ .

You could specify the width of all but the last table cells and add a table-layout:fixed and a width to the table.

You could set

table tr ul.actions {margin: 0; white-space:nowrap;}

(or set this for the last TD as Sander suggested instead).

This forces the inline-LIs not to break. Unfortunately this does not lead to a new width calculation in the containing UL (and this parent TD), and therefore does not autosize the last TD.

This means: if an inline element has no given width, a TD's width is always computed automatically first (if not specified). Then its inline content with this calculated width gets rendered and the white-space-property is applied, stretching its content beyond the calculated boundaries.

So I guess it's not possible without having an element within the last TD with a specific width.

Here's what I found during debug.

Here is how the problem can solved in Java 8 just like the answer by shamimz.

Source : http://docs.oracle.com/javase/tutorial/datetime/iso/period.html

LocalDate today = LocalDate.now();
LocalDate birthday = LocalDate.of(1960, Month.JANUARY, 1);

Period p = Period.between(birthday, today);
long p2 = ChronoUnit.DAYS.between(birthday, today);

System.out.println("You are " + p.getYears() + " years, " + p.getMonths() + " months, and " + p.getDays() + " days old. (" + p2 + " days total)");

The code produces output similar to the following:

You are 53 years, 4 months, and 29 days old. (19508 days total)

We have to use LocalDateTime http://docs.oracle.com/javase/8/docs/api/java/time/LocalDateTime.html to get hour,minute,second differences.

Basically there are four logical steps.

1. Create a new Identity column. Turn on Insert Identity for this new column.

2. Insert the data from the source column (the column you wished to convert to Identity) to this new column.

3. Turn off the Insert Identity for the new column.

4. Drop your source column & rename the new column to the name of the source column.

There may be some more complexities like working across multiple servers etc.

Please refer the following article for the steps (using ssms & T-sql). These steps are intended for beginners with less grip on T-SQL.

Yet another recursive directory tree archiving, implemented as an extension to ZipArchive. As a bonus, a single-statement tree compression helper function is included. Optional localname is supported, as in other ZipArchive functions. Error handling code to be added...

class ExtendedZip extends ZipArchive {

    // Member function to add a whole file system subtree to the archive
    public function addTree($dirname, $localname = '') {
        if ($localname)
            $this->addEmptyDir($localname);
        $this->_addTree($dirname, $localname);
    }

    // Internal function, to recurse
    protected function _addTree($dirname, $localname) {
        $dir = opendir($dirname);
        while ($filename = readdir($dir)) {
            // Discard . and ..
            if ($filename == '.' || $filename == '..')
                continue;

            // Proceed according to type
            $path = $dirname . '/' . $filename;
            $localpath = $localname ? ($localname . '/' . $filename) : $filename;
            if (is_dir($path)) {
                // Directory: add & recurse
                $this->addEmptyDir($localpath);
                $this->_addTree($path, $localpath);
            }
            else if (is_file($path)) {
                // File: just add
                $this->addFile($path, $localpath);
            }
        }
        closedir($dir);
    }

    // Helper function
    public static function zipTree($dirname, $zipFilename, $flags = 0, $localname = '') {
        $zip = new self();
        $zip->open($zipFilename, $flags);
        $zip->addTree($dirname, $localname);
        $zip->close();
    }
}

// Example
ExtendedZip::zipTree('/foo/bar', '/tmp/archive.zip', ZipArchive::CREATE);

You've already got it: A if test else B is a valid Python expression. The only problem with your dict comprehension as shown is that the place for an expression in a dict comprehension must have two expressions, separated by a colon:

{ (some_key if condition else default_key):(something_if_true if condition
          else something_if_false) for key, value in dict_.items() }

The final if clause acts as a filter, which is different from having the conditional expression.

How you test depends on the Property's DataType:

| Type                                 | Test                            | Test2
| Numeric (Long, Integer, Double etc.) | If obj.Property = 0 Then        | 
| Boolen (True/False)                  | If Not obj.Property Then        | If obj.Property = False Then
| Object                               | If obj.Property Is Nothing Then |
| String                               | If obj.Property = "" Then       | If LenB(obj.Property) = 0 Then
| Variant                              | If obj.Property = Empty Then    |

You can tell the DataType by pressing F2 to launch the Object Browser and looking up the Object. Another way would be to just use the TypeName function:MsgBox TypeName(obj.Property)

Make sure the Docker daemon is running:

service docker start

That fixed it for me!

Starting with TypeScript 2.2 using dot notation to access indexed properties is allowed. You won't get error TS2339 on your example.

See Dotted property for types with string index signatures in TypeScript 2.2 release note.

If you do git update-index --assume-unchanged file.csproj, git won't check file.csproj for changes automatically: that will stop them coming up in git status whenever you change them. So you can mark all your .csproj files this way- although you'll have to manually mark any new ones that the upstream repo sends you. (If you have them in your .gitignore or .git/info/exclude, then ones you create will be ignored)

I'm not entirely sure what .csproj files are... if they're something along the lines of IDE configurations (similar to Eclipse's .eclipse and .classpath files) then I'd suggest they should simply never be source-controlled at all. On the other hand, if they're part of the build system (like Makefiles) then clearly they should--- and a way to pick up optional local changes (e.g. from a local.csproj a la config.mk) would be useful: divide the build up into global parts and local overrides.

Simply convert boolean field to integer and do a sum. This will work on postgresql :

select sum(myCol::int) from <table name>

Hope that helps!

Good evening,

I prefer to just have a simple extension method:

Date.prototype.startOfWeek = function (pStartOfWeek) {
    var mDifference = this.getDay() - pStartOfWeek;

    if (mDifference < 0) {
        mDifference += 7;
    }

    return new Date(this.addDays(mDifference * -1));
}

You'll notice this actually utilizes another extension method that I use:

Date.prototype.addDays = function (pDays) {
    var mDate = new Date(this.valueOf());
    mDate.setDate(mDate.getDate() + pDays);
    return mDate;
};

Now, if your weeks start on Sunday, pass in a "0" for the pStartOfWeek parameter, like so:

var mThisSunday = new Date().startOfWeek(0);

Similarly, if your weeks start on Monday, pass in a "1" for the pStartOfWeek parameter:

var mThisMonday = new Date().startOfWeek(1);

Regards,

You can also use an image:

UIImage *maskingImage = [UIImage imageNamed:@"bannerBarBottomMask.png"];
CALayer *maskingLayer = [CALayer layer];
maskingLayer.frame = CGRectMake(-(self.yourView.frame.size.width - self.yourView.frame.size.width) / 2
                                , 0
                                , maskingImage.size.width
                                , maskingImage.size.height);
[maskingLayer setContents:(id)[maskingImage CGImage]];
[self.yourView.layer setMask:maskingLayer];

Updating with more options

list1 = ['foo', 'fob', 'faz', 'funk']
addstring = 'bar'
for index, value in enumerate(list1):
    list1[index] = addstring + value #this will prepend the string
    #list1[index] = value + addstring this will append the string

Avoid using keywords as variables like 'list', renamed 'list' as 'list1' instead

If you need to do a file upload, you'll need to use MediaType.MULTIPART_FORM_DATA_TYPE. Looks like MultivaluedMap cannot be used with that so here's a solution with FormDataMultiPart.

InputStream stream = getClass().getClassLoader().getResourceAsStream(fileNameToUpload);

FormDataMultiPart part = new FormDataMultiPart();
part.field("String_key", "String_value");
part.field("fileToUpload", stream, MediaType.TEXT_PLAIN_TYPE);
String response = WebResource.type(MediaType.MULTIPART_FORM_DATA_TYPE).post(String.class, part);

If you need to use a function to cast:

var list1 = new List<Type1>();
var list2 = new List<Type2>();

list2 = list1.ConvertAll(x => myConvertFuntion(x));

Where my custom function is:

private Type2 myConvertFunction(Type1 obj){
   //do something to cast Type1 into Type2
   return new Type2();
}

U may do as I have written from my deleted account (ban for new posts :( there was). Its rather simple and nice looking.

Im using 3-rd one of these 3 ones usually, also I wasny checking 1 and 2 version.

from matplotlib.pyplot import cm
import numpy as np

#variable n should be number of curves to plot (I skipped this earlier thinking that it is obvious when looking at picture - sorry my bad mistake xD): n=len(array_of_curves_to_plot)
#version 1:

color=cm.rainbow(np.linspace(0,1,n))
for i,c in zip(range(n),color):
   ax1.plot(x, y,c=c)

#or version 2: - faster and better:

color=iter(cm.rainbow(np.linspace(0,1,n)))
c=next(color)
plt.plot(x,y,c=c)

#or version 3:

color=iter(cm.rainbow(np.linspace(0,1,n)))
for i in range(n):
   c=next(color)

Slightly off-topic but if you ever needed a class-based component that never renders anything and you are happy to use some yet-to-be-standardised ES syntax, you might want to go:

render = () => null

This is basically an arrow method that currently requires the transform-class-properties Babel plugin. React will not let you define a component without the render function and this is the most concise form satisfying this requirement that I can think of.

I'm currently using this trick in a variant of ScrollToTop borrowed from the react-router documentation. In my case, there's only a single instance of the component and it doesn't render anything, so a short form of "render null" fits nice in there.

iirc :

cat filename.txt | awk '{ print $2 $4 }'

or, as mentioned in the comments :

awk '{ print $2 $4 }' filename.txt

I used a trial version of ZOC Terminal Emulator and it worked. It readily accepts the Amazon's *.pem files.

The trick is though, that you need to specify "ec2-user" instead of "root" for the username - despite the example shown in the EC2 console, which is wrong! ;-)

no_of_rows = 3  # For n by n, and even works for n by m but just give no of rows
matrix = [[int(j) for j in input().split()] for i in range(n)]
print(matrix)

InvariantCulture

Uses a "standard" set of character orderings (a,b,c, ... etc.). This is in contrast to some specific locales, which may sort characters in different orders ('a-with-acute' may be before or after 'a', depending on the locale, and so on).

Ordinal

On the other hand, looks purely at the values of the raw byte(s) that represent the character.

There's a great sample at http://msdn.microsoft.com/en-us/library/e6883c06.aspx that shows the results of the various StringComparison values. All the way at the end, it shows (excerpted):

StringComparison.InvariantCulture:
LATIN SMALL LETTER I (U+0069) is less than LATIN SMALL LETTER DOTLESS I (U+0131)
LATIN SMALL LETTER I (U+0069) is less than LATIN CAPITAL LETTER I (U+0049)
LATIN SMALL LETTER DOTLESS I (U+0131) is greater than LATIN CAPITAL LETTER I (U+0049)

StringComparison.Ordinal:
LATIN SMALL LETTER I (U+0069) is less than LATIN SMALL LETTER DOTLESS I (U+0131)
LATIN SMALL LETTER I (U+0069) is greater than LATIN CAPITAL LETTER I (U+0049)
LATIN SMALL LETTER DOTLESS I (U+0131) is greater than LATIN CAPITAL LETTER I (U+0049)

You can see that where InvariantCulture yields (U+0069, U+0049, U+00131), Ordinal yields (U+0049, U+0069, U+00131).

Add new column to Table

ALTER TABLE [table]
ADD Column1 Datatype

E.g

ALTER TABLE [test]
ADD ID Int

If User wants to make it auto incremented then

ALTER TABLE [test]
ADD ID Int IDENTITY(1,1) NOT NULL

fout=open("out.csv","a")
for num in range(1,201):
    for line in open("sh"+str(num)+".csv"):
         fout.write(line)    
fout.close()

There's no "simple command" to do that. You can write a function, or take your choice of several that are available online in various code repositories. I use this:

function get-loggedonuser ($computername){

#mjolinor 3/17/10

$regexa = '.+Domain="(.+)",Name="(.+)"$'
$regexd = '.+LogonId="(\d+)"$'

$logontype = @{
"0"="Local System"
"2"="Interactive" #(Local logon)
"3"="Network" # (Remote logon)
"4"="Batch" # (Scheduled task)
"5"="Service" # (Service account logon)
"7"="Unlock" #(Screen saver)
"8"="NetworkCleartext" # (Cleartext network logon)
"9"="NewCredentials" #(RunAs using alternate credentials)
"10"="RemoteInteractive" #(RDP\TS\RemoteAssistance)
"11"="CachedInteractive" #(Local w\cached credentials)
}

$logon_sessions = @(gwmi win32_logonsession -ComputerName $computername)
$logon_users = @(gwmi win32_loggedonuser -ComputerName $computername)

$session_user = @{}

$logon_users |% {
$_.antecedent -match $regexa > $nul
$username = $matches[1] + "\" + $matches[2]
$_.dependent -match $regexd > $nul
$session = $matches[1]
$session_user[$session] += $username
}


$logon_sessions |%{
$starttime = [management.managementdatetimeconverter]::todatetime($_.starttime)

$loggedonuser = New-Object -TypeName psobject
$loggedonuser | Add-Member -MemberType NoteProperty -Name "Session" -Value $_.logonid
$loggedonuser | Add-Member -MemberType NoteProperty -Name "User" -Value $session_user[$_.logonid]
$loggedonuser | Add-Member -MemberType NoteProperty -Name "Type" -Value $logontype[$_.logontype.tostring()]
$loggedonuser | Add-Member -MemberType NoteProperty -Name "Auth" -Value $_.authenticationpackage
$loggedonuser | Add-Member -MemberType NoteProperty -Name "StartTime" -Value $starttime

$loggedonuser
}

}

Well, after searching around and cobbling together various points from around StackOverflow (gee, I love this place already), most of the problems were already past this stage. I did manage to work out an answer to my problem though.

How to create a resource:

In my case, I want to create an icon. It's a similar process, no matter what type of data you want to add as a resource though.

• Right click the project you want to add a resource to. Do this in the Solution Explorer. Select the "Properties" option from the list.
• Click the "Resources" tab.
• The first button along the top of the bar will let you select the type of resource you want to add. It should start on string. We want to add an icon, so click on it and select "Icons" from the list of options.
• Next, move to the second button, "Add Resource". You can either add a new resource, or if you already have an icon already made, you can add that too. Follow the prompts for whichever option you choose.
• At this point, you can double click the newly added resource to edit it. Note, resources also show up in the Solution Explorer, and double clicking there is just as effective.

How to use a resource:

Great, so we have our new resource and we're itching to have those lovely changing icons... How do we do that? Well, lucky us, C# makes this exceedingly easy.

There is a static class called Properties.Resources that gives you access to all your resources, so my code ended up being as simple as:

paused = !paused;
if (paused)
    notifyIcon.Icon = Properties.Resources.RedIcon;
else
    notifyIcon.Icon = Properties.Resources.GreenIcon;

Done! Finished! Everything is simple when you know how, isn't it?

The script tag to the api has changed recently. Use something like this to query the Geocoding API and get the JSON object back

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/geocode/json?address=THE_ADDRESS_YOU_WANT_TO_GEOCODE&key=YOUR_API_KEY"></script>

The address could be something like

1600+Amphitheatre+Parkway,+Mountain+View,+CA (URI Encoded; you should Google it. Very useful)

or simply

1600 Amphitheatre Parkway, Mountain View, CA

By entering this address https://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&key=YOUR_API_KEY inside the browser, along with my API Key, I get back a JSON object which contains the Latitude & Longitude for the city of Moutain view, CA.

Since dob is DATE data type, you need to convert the literal to DATE using TO_DATE and the proper format model. The syntax is:

TO_DATE('<date_literal>', '<format_model>')

For example,

SQL> CREATE TABLE t(dob DATE);

Table created.

SQL> INSERT INTO t(dob) VALUES(TO_DATE('17/12/2015', 'DD/MM/YYYY'));

1 row created.

SQL> COMMIT;

Commit complete.

SQL> SELECT * FROM t;

DOB
----------
17/12/2015

A DATE data type contains both date and time elements. If you are not concerned about the time portion, then you could also use the ANSI Date literal which uses a fixed format 'YYYY-MM-DD' and is NLS independent.

For example,

SQL> INSERT INTO t(dob) VALUES(DATE '2015-12-17');

1 row created.

Guessing at all the things omitted from the original question, but, assuming Python 2.x the key is to read the error messages carefully: in particular where you call 'encode' but the message says 'decode' and vice versa, but also the types of the values included in the messages.

In the first example string is of type unicode and you attempted to decode it which is an operation converting a byte string to unicode. Python helpfully attempted to convert the unicode value to str using the default 'ascii' encoding but since your string contained a non-ascii character you got the error which says that Python was unable to encode a unicode value. Here's an example which shows the type of the input string:

>>> u"\xa0".decode("ascii", "ignore")

Traceback (most recent call last):
  File "<pyshell#7>", line 1, in <module>
    u"\xa0".decode("ascii", "ignore")
UnicodeEncodeError: 'ascii' codec can't encode character u'\xa0' in position 0: ordinal not in range(128)

In the second case you do the reverse attempting to encode a byte string. Encoding is an operation that converts unicode to a byte string so Python helpfully attempts to convert your byte string to unicode first and, since you didn't give it an ascii string the default ascii decoder fails:

>>> "\xc2".encode("ascii", "ignore")

Traceback (most recent call last):
  File "<pyshell#6>", line 1, in <module>
    "\xc2".encode("ascii", "ignore")
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 0: ordinal not in range(128)

Clean up, check all check box => This work for me

I have mysql data folder replaced by a windows directory junction. I suspect ib_logfile0/1 and/or ibdata1 is corrupted.

Just try to delete those files and computername.err. Then restart mysql service. That's what I did, with success.

Copying ibdata1 files, after a full reinstallation of mysql, to the junction dir and replacing dir by the junction, restarting mysql, was not enough.

You have to let mysql rebuild those files.

if you add the print code to check the type of real, you will see that real is a string, not an Entry so there is no delete attribute.

def res(real, secret):
    print(type(real))
    if secret==eval(real):
        showinfo(message='that is right!')
    real.delete(0, END)

>> output: <class 'str'>

Solution:

secret = randrange(1,100)
print(secret)

def res(real, secret):
    if secret==eval(real):
        showinfo(message='that is right!')
    ent.delete(0, END)    # we call the entry an delete its content

def guess():

    ge = Tk()
    ge.title('guessing game')

    Label(ge, text="what is your guess:").pack(side=TOP)

    global ent    # Globalize ent to use it in other function
    ent = Entry(ge)
    ent.pack(side=TOP)

    btn=Button(ge, text="Enter", command=lambda: res(ent.get(),secret))
    btn.pack(side=LEFT)

    ge.mainloop()

It should work.

Your vncserver have a configuration file somewher that set the display number. To do it automaticaly, one solution is to parse this file, extract the number and set it correctly. A simpler (better) is to have this display number set in a config script and use it in both your VNC server config and in your init scripts.

Get rid of the values keyword and the parens. You can see an example here.

This is basic INSERT syntax:

INSERT INTO "table_name" ("column1", "column2", ...)
VALUES ("value1", "value2", ...);

This is the INSERT SELECT syntax:

INSERT INTO "table1" ("column1", "column2", ...)
SELECT "column3", "column4", ...
FROM "table2";

The for loop iterates over the elements of the array, not its indexes. Suppose you have a list ar = [2, 4, 6]:

When you iterate over it with for i in ar: the values of i will be 2, 4 and 6. So, when you try to access ar[i] for the first value, it might work (as the last position of the list is 2, a[2] equals 6), but not for the latter values, as a[4] does not exist.

If you intend to use indexes anyhow, try using for index, value in enumerate(ar):, then theSum = theSum + ar[index] should work just fine.

Working on a project I was stuck for some time on this concept - I ended up with a similar answer to Method 1 by @GSerg that worked great. Essentially I defined two formula ranges (using a few variables) and then used the Union concept. My example is from a larger project that I'm working on but hopefully the portion of code below can help some other people who might not know how to use the Union concept in conjunction with defined ranges and variables. I didn't include the entire code because at this point it's fairly long - if anyone wants more insight feel free to let me know.

First I declared all my variables as Public

Then I defined/set each variable

Lastly I set a new variable "SelectRanges" as the Union between the two other FormulaRanges

Public r As Long
Public c As Long
Public d As Long
Public FormulaRange3 As Range
Public FormulaRange4 As Range
Public SelectRanges As Range

With Sheet8




  c = pvt.DataBodyRange.Columns.Count + 1

  d = 3

  r = .Cells(.Rows.Count, 1).End(xlUp).Row

Set FormulaRange3 = .Range(.Cells(d, c + 2), .Cells(r - 1, c + 2))
    FormulaRange3.NumberFormat = "0"
    Set FormulaRange4 = .Range(.Cells(d, c + c + 2), .Cells(r - 1, c + c + 2))
    FormulaRange4.NumberFormat = "0"
    Set SelectRanges = Union(FormulaRange3, FormulaRange4)

My code is amazing it just took 00:00:00.0007143 less than milisecond with 34 file in folder

You haven't at time of writing described what you are going to do with the response or what its content type is. An answer already contains a very basic usage of MSXML2.XMLHTTP (I recommend the more explicit MSXML2.XMLHTTP.3.0 progID) however you may need to do different things with the response, it may not be text.

The XMLHTTP also has a responseBody property which is a byte array version of the reponse and there is a responseStream which is an IStream wrapper for the response.

Note that in a server-side requirement (e.g., VBScript hosted in ASP) you would use MSXML.ServerXMLHTTP.3.0 or WinHttp.WinHttpRequest.5.1 (which has a near identical interface).

Here is an example of using XmlHttp to fetch a PDF file and store it:-

Dim oXMLHTTP
Dim oStream

Set oXMLHTTP = CreateObject("MSXML2.XMLHTTP.3.0")

oXMLHTTP.Open "GET", "http://someserver/folder/file.pdf", False
oXMLHTTP.Send

If oXMLHTTP.Status = 200 Then
    Set oStream = CreateObject("ADODB.Stream")
    oStream.Open
    oStream.Type = 1
    oStream.Write oXMLHTTP.responseBody
    oStream.SaveToFile "c:\somefolder\file.pdf"
    oStream.Close
End If

Also a little known feature in Twig is string interpolation:

{{ "http://#{app.request.host}" }}

Yes. Bootstrap uses CSS transitions so it can be done easily without any Javascript. Just use CSS3. Please take a look at

carousel.carousel-fade

in the CSS of the following examples:

• http://jsfiddle.net/seemly/ww67B/123/
• http://bootply.com/86170
• http://codepen.io/Rowno/pen/Afykb

The parameter(s) to isset() must be a variable reference and not an expression (in your case a concatenation); but you can group multiple conditions together like this:

if (isset($_POST['search_term'], $_POST['postcode'])) {
}

This will return true only if all arguments to isset() are set and do not contain null.

Note that isset($var) and isset($var) == true have the same effect, so the latter is somewhat redundant.

Update

The second part of your expression uses empty() like this:

empty ($_POST['search_term'] . $_POST['postcode']) == false

This is wrong for the same reasons as above. In fact, you don't need empty() here, because by that time you would have already checked whether the variables are set, so you can shortcut the complete expression like so:

isset($_POST['search_term'], $_POST['postcode']) && 
    $_POST['search_term'] && 
    $_POST['postcode']

Or using an equivalent expression:

!empty($_POST['search_term']) && !empty($_POST['postcode'])

Final thoughts

You should consider using filter functions to manage the inputs:

$data = filter_input_array(INPUT_POST, array(
    'search_term' => array(
        'filter' => FILTER_UNSAFE_RAW,
        'flags' => FILTER_NULL_ON_FAILURE,
    ),
    'postcode' => array(
        'filter' => FILTER_UNSAFE_RAW,
        'flags' => FILTER_NULL_ON_FAILURE,
    ),
));

if ($data === null || in_array(null, $data, true)) {
    // some fields are missing or their values didn't pass the filter
    die("You did something naughty");
}

// $data['search_term'] and $data['postcode'] contains the fields you want

Btw, you can customize your filters to check for various parts of the submitted values.

Radu Simionescu - awesome work! and below Your solution for Swift lovers:

@IBAction func showSecondControlerAndCloseCurrentOne(sender: UIButton) {
    let secondViewController = storyboard?.instantiateViewControllerWithIdentifier("ConrollerStoryboardID") as UIViewControllerClass // change it as You need it
    var presentingVC = self.presentingViewController
    self.dismissViewControllerAnimated(false, completion: { () -> Void   in
        presentingVC!.presentViewController(secondViewController, animated: true, completion: nil)
    })
}

I think that is easier than this.

• First, create a blank target database.
• Then, in "SQL Server Management Studio" restore wizard, look for the option to overwrite target database. It is in the 'Options' tab and is called 'Overwrite the existing database (WITH REPLACE)'. Check it.
• Remember to select target files in 'Files' page.

You can change 'tabs' at left side of the wizard (General, Files, Options)

You don't need to use JsonConverterAttribute, keep your model clean, also use CustomCreationConverter, the code is simpler:

public class SampleConverter : CustomCreationConverter<ISample>
{
    public override ISample Create(Type objectType)
    {
        return new Sample();
    }
}

Then:

var sz = JsonConvert.SerializeObject( sampleGroupInstance );
JsonConvert.DeserializeObject<SampleGroup>( sz, new SampleConverter());

Documentation: Deserialize with CustomCreationConverter

Try this

SELECT CONVERT(varchar(11),getdate(),101) -- Converts to 'mm/dd/yyyy'

SELECT CONVERT(varchar(11),getdate(),103) -- Converts to 'dd/mm/yyyy'
