File.isFile() is false if the file / directory does not exist, so you can't use it to test whether you're trying to create a directory. But that's not the first issue here.

The issue is that the intermediate directories don't exist. You want to call f.mkdirs() first.

$ echo | mutt -a syslogs.tar.gz [email protected]

But it uses mutt, not mail (or mailx).

You can compare different methods very well explained on this page: http://blog.themeforest.net/tutorials/vertical-centering-with-css/

The method they recommend is adding a empty floating element before the content you cant centered, and clearing it. It doesn't have the downside you mentioned.

I forked your JSBin to apply it : http://jsbin.com/iquviq/7/edit

HTML

<div id="floater">
</div>

<div id="content">
  Content here
</div>

CSS

#floater {
  float: left; 
  height: 50%; 
  margin-bottom: -300px;
}

#content {
  clear: both; 
  width: 200px;
  height: 600px;
  position: relative; 
  margin: auto;
}

I think the answer to this question pretty much sums up the problem with your question.

If what you want to do is find out whether a given host will accept TCP connections on port 80, you can do this:

$host = '193.33.186.70'; 
$port = 80; 
$waitTimeoutInSeconds = 1; 
if($fp = fsockopen($host,$port,$errCode,$errStr,$waitTimeoutInSeconds)){   
   // It worked 
} else {
   // It didn't work 
} 
fclose($fp);

For anything other than TCP it will be more difficult (although since you specify 80, I guess you are looking for an active HTTP server, so TCP is what you want). TCP is sequenced and acknowledged, so you will implicitly receive a returned packet when a connection is successfully made. Most other transport protocols (commonly UDP, but others as well) do not behave in this manner, and datagrams will not be acknowledged unless the overlayed Application Layer protocol implements it.

The fact that you are asking this question in this manner tells me you have a fundamental gap in your knowledge on Transport Layer protocols. You should read up on ICMP and TCP, as well as the OSI Model.

Also, here's a slightly cleaner version to ping to hosts.

// Function to check response time
function pingDomain($domain){
    $starttime = microtime(true);
    $file      = fsockopen ($domain, 80, $errno, $errstr, 10);
    $stoptime  = microtime(true);
    $status    = 0;

    if (!$file) $status = -1;  // Site is down
    else {
        fclose($file);
        $status = ($stoptime - $starttime) * 1000;
        $status = floor($status);
    }
    return $status;
}

On Mac OS, I found the best solution here. Quoting the author, two simple steps are:

1) Open Terminal and do the following:

export http_proxy=http://staff-proxy.ul.ie:8080
export HTTP_PROXY=http://staff-proxy.ul.ie:8080

2) Run R and do the following:

Sys.setenv(http_proxy="http://staff-proxy.ul.ie:8080")

double-check this with:

Sys.getenv("http_proxy")

I am behind university proxy, and this solution worked perfectly. The major issue is to export the items in Terminal before running R, both in upper- and lower-case.

You have writer.close(); in your code. So bash receives EOF on its stdin and exits. Then you get Broken pipe when trying to read from the stdoutof the defunct bash.

Like this?

In LINQ:

var sortedList = originalList.OrderBy(foo => !foo.AVC)
                             .ToList();

Or in-place:

originalList.Sort((foo1, foo2) => foo2.AVC.CompareTo(foo1.AVC));

As Jon Skeet says, the trick here is knowing that false is considered to be 'smaller' than true.

If you find that you are doing these ordering operations in lots of different places in your code, you might want to get your type Foo to implement the IComparable<Foo> and IComparable interfaces.

The performant function Python provides for this is set.issubset. It does have a few restrictions that make it unclear if it's the answer to your question, however.

A list may contain items multiple times and has a specific order. A set does not. Additionally, sets only work on hashable objects.

Are you asking about subset or subsequence (which means you'll want a string search algorithm)? Will either of the lists be the same for many tests? What are the datatypes contained in the list? And for that matter, does it need to be a list?

Your other post intersect a dict and list made the types clearer and did get a recommendation to use dictionary key views for their set-like functionality. In that case it was known to work because dictionary keys behave like a set (so much so that before we had sets in Python we used dictionaries). One wonders how the issue got less specific in three hours.

Try using cURL instead. cURL implements a cookie jar, while file_get_contents doesn't.

For those of you who faced this issue while creating a controller through the context menu, reopening Visual Studio as an administrator fixed it.

Pass the intent with value on First Activity:

Intent intent = new Intent(FirstActivity.this, SecondActivity.class);
intent.putExtra("uid", uid.toString());
intent.putExtra("pwd", pwd.toString());
startActivity(intent);

Receive intent on second Activity;-

Intent intent = getIntent();
String user = intent.getStringExtra("uid");
String pass = intent.getStringExtra("pwd");

We use generally two method in intent to send the value and to get the value. For sending the value we will use intent.putExtra("key", Value); and during receive intent on another activity we will use intent.getStringExtra("key"); to get the intent data as String or use some other available method to get other types of data (Integer, Boolean, etc.). The key may be any keyword to identify the value means that what value you are sharing. Hope it will work for you.

You're looking for an ellipsoid formula.

The best place I've found to start coding is based on the Geo::Ellipsoid library from CPAN. It gives you a baseline to create your tests off of and to compare your results with its results. I used it as the basis for a similar library for PHP at my previous employer.

Geo::Ellipsoid

Take a look at the location method. Call it twice and you've got your bbox.

You didn't post what language you were using. There may already be a geocoding library available for you.

Oh, and if you haven't figured it out by now, Google maps uses the WGS84 ellipsoid.

df.to_html() has a columns parameter.

Just pass the columns into the to_html() method.

df.to_html(columns=['A','B','C','D','E','F','G'])

Do you mean like this?

var hello1 = document.getElementById('hello1');
hello1.id = btoa(hello1.id);

To further the example, say you wanted to get all elements with the class 'abc'. We can use querySelectorAll() to accomplish this:

HTML

<div class="abc"></div>
<div class="abc"></div>

JS

var abcElements = document.querySelectorAll('.abc');

// Set their ids
for (var i = 0; i < abcElements.length; i++)
    abcElements[i].id = 'abc-' + i;

This will assign the ID 'abc-<index number>' to each element. So it would come out like this:

<div class="abc" id="abc-0"></div>
<div class="abc" id="abc-1"></div>

To create an element and assign an id we can use document.createElement() and then appendChild().

var div = document.createElement('div');
div.id = 'hello1';

var body = document.querySelector('body');
body.appendChild(div);

Update

You can set the id on your element like this if your script is in your HTML file.

<input id="{{str(product["avt"]["fto"])}}" >
<span>New price :</span>
<span class="assign-me">

<script type="text/javascript">
    var s = document.getElementsByClassName('assign-me')[0];
    s.id = btoa({{str(produit["avt"]["fto"])}});
</script>

Your requirements still aren't 100% clear though.

Maybe you can try the following :

var i = 0;
function AjaxSendForm(url, placeholder, form, append) {
var data = $(form).serialize();
append = (append === undefined ? false : true); // whatever, it will evaluate to true or false only
$.ajax({
    type: 'POST',
    url: url,
    data: data,
    beforeSend: function() {
        // setting a timeout
        $(placeholder).addClass('loading');
        i++;
    },
    success: function(data) {
        if (append) {
            $(placeholder).append(data);
        } else {
            $(placeholder).html(data);
        }
    },
    error: function(xhr) { // if error occured
        alert("Error occured.please try again");
        $(placeholder).append(xhr.statusText + xhr.responseText);
        $(placeholder).removeClass('loading');
    },
    complete: function() {
        i--;
        if (i <= 0) {
            $(placeholder).removeClass('loading');
        }
    },
    dataType: 'html'
});
}

This way, if the beforeSend statement is called before the complete statement i will be greater than 0 so it will not remove the class. Then only the last call will be able to remove it.

I cannot test it, let me know if it works or not.

Do you mean full calendar days, or groups of 24 hours?

For simply 24 hours, assuming you're using Python's datetime, then the timedelta object already has a days property:

days = (a - b).days

For calendar days, you'll need to round a down to the nearest day, and b up to the nearest day, getting rid of the partial day on either side:

roundedA = a.replace(hour = 0, minute = 0, second = 0, microsecond = 0)
roundedB = b.replace(hour = 0, minute = 0, second = 0, microsecond = 0)
days = (roundedA - roundedB).days

There are a couple of variants of a rename command, in your case, it may be as simple as

rename ABC XYZ *.dat

You may have a version which takes a Perl regex;

rename 's/ABC/XYZ/' *.dat

select count(*) from dbo.tablename where address_line_1 LIKE '%[\'']%' {eSCAPE'\'}

If you just use rm, you will need to follow it up with git add <fileRemoved>. git rm does this in one step.

You can also use git rm --cached which will remove the file from the index (staging it for deletion on the next commit), but keep your copy in the local file system.

There aren't any quotes. It's just VS debugger. Try printing to the console or saving to a file and you'll see. As a side note: always dispose disposable objects:

using (var stringWriter = new StringWriter())
using (var xmlTextWriter = XmlWriter.Create(stringWriter))
{
    xmlDoc.WriteTo(xmlTextWriter);
    xmlTextWriter.Flush();
    return stringWriter.GetStringBuilder().ToString();
}

if in string:

string yourVar = yourTextBoxname.Text;

if in numbers:

int yourVar = int.Parse(yourTextBoxname.Text);

element.InnerHtml= allmycontent: will re-write everything inside the element. You must use a variable let allmycontent="this is what I want to print inside this element"to store the whole content you want inside this element. If not each time you will call this function, the content of your element will be erased and replace with the last call you made of it.

document.write(): can be use several times, each time the content will be printed where the call is made on the page.

But be aware: document.write() method is only useful for inserting content at page creation . So use it for not repeating when having a lot of data to write like a catalogue of products or images.

Here a simple example: all your li for your aside menu are stored in an array "tab", you can create a js script with the script tag directly into the html page and then use the write method in an iterative function where you want to insert those li on the page.

<script type="text/javascript">
document.write("<ul>");
for (var i=0; i<=tab.length; i++){
    document.write(tab[i]);
    }document.write("</ul>");
</script>`

This works because Js is interpreted in a linear way during the loading. So make sure your script is at the right place in your html page.You can also use an external Js file, but then again you must declare it at the place where you want it to be interpreted.

For this reason, document.write cannot be called for writing something on your page as a result of a "user interaction" (like click or hover), because then the DOM has been created and write method will, like said above, write a new page (purge the actual execution stack and start a new stack and a new DOM tree). In this case use:

element.innerHTML=("Myfullcontent");

To learn more about document's methods: open your console: document; then open: __proto__: HTMLDocumentPrototype

You'll see the function property "write" in the document object. You can also use document.writeln which add a new line at each statement. To learn more about a function/method, just write its name into the console with no parenthesis: document.write; The console will return a description instead of calling it.

ReducedForm is a type, so you cannot say

ReducedForm.iSimplifiedNumerator = iNumerator/iGreatCommDivisor;

You can only use the . operator on an instance:

ReducedForm rf;
rf.iSimplifiedNumerator = iNumerator/iGreatCommDivisor;

This css script might be useful to all - It is not for syntax highlighting but works well for presenting the source code in original format :

 <pre style="font-family: Andale Mono, Lucida Console, Monaco, fixed, monospace; 
                color: #000000; background-color: #eee;
                font-size: 12px; border: 1px dashed #999999;
                line-height: 14px; padding: 5px; 
                overflow: auto; width: 100%">
       <code style="color:#000000;word-wrap:normal;">

            <<<<<<<YOUR CODE HERE>>>>>>>

       </code>
 </pre>

How to use :

1. Paste this snippet in text editor,
2. paste your code in <<<<<<>>>>>> block.
3. Copy all and
4. paste to HTML view in blogger(or any other) post editor.

BENEFITS : Simple and easy to use, less configuration, easy to reconfigure, no extra software

Just Go to Model file of the corresponding Controller and check the primary key filed name

such as

protected $primaryKey = 'info_id';

here info id is field name available in database table

More info can be found at "Primary Keys" section of the docs.

Don't know if this is an option, but it would work very similar to Zend's pdf library, but you don't need to load a bunch of extra code (the zend framework). It just extends FPDF.

http://www.setasign.de/products/pdf-php-solutions/fpdi/

Here you can basically do the same thing. Load the PDF, write over top of it, and then save to a new PDF. In FPDI you basically insert the PDF as an image so you can put whatever you want over it.

But again, this uses FPDF, so if you don't want to use that, then it won't work.

Working with Git 2.3.2 ...

git branch --set-upstream-to myfork/master

Now status, push and pull are pointed to myfork remote

I needed to do a query to get me all groups with a managedBy value set (not empty) and this gave some nice results:

(!(!managedBy=*))

The main choice is do you want to treat the HTTP status code as part of your REST API or not.

Both ways work fine. I agree that, strictly speaking, one of the ideas of REST is that you should use the HTTP Status code as a part of your API (return 200 or 201 for a successful operation and a 4xx or 5xx depending on various error cases.) However, there are no REST police. You can do what you want. I have seen far more egregious non-REST APIs being called "RESTful."

At this point (August, 2015) I do recommend that you use the HTTP Status code as part of your API. It is now much easier to see the return code when using frameworks than it was in the past. In particular, it is now easier to see the non-200 return case and the body of non-200 responses than it was in the past.

The HTTP Status code is part of your api

1. You will need to carefully pick 4xx codes that fit your error conditions. You can include a rest, xml, or plaintext message as the payload that includes a sub-code and a descriptive comment.

2. The clients will need to use a software framework that enables them to get at the HTTP-level status code. Usually do-able, not always straight-forward.

3. The clients will have to distinguish between HTTP status codes that indicate a communications error and your own status codes that indicate an application-level issue.

The HTTP Status code is NOT part of your api

1. The HTTP status code will always be 200 if your app received the request and then responded (both success and error cases)

2. ALL of your responses should include "envelope" or "header" information. Typically something like:

   envelope_ver: 1.0
   status:  # use any codes you like. Reserve a code for success. 
   msg: "ok" # A human string that reflects the code. Useful for debugging.
   data: ...  # The data of the response, if any.

3. This method can be easier for clients since the status for the response is always in the same place (no sub-codes needed), no limits on the codes, no need to fetch the HTTP-level status-code.

Here's a post with a similar idea: http://yuiblog.com/blog/2008/10/15/datatable-260-part-one/

Main issues:

1. Be sure to include version numbers so you can later change the semantics of the api if needed.

2. Document...

HostListener should be the proper way to bind event into your component:

@Component({
  selector: 'your-element'
})

export class YourElement {
  @HostListener('click', ['$event']) onClick(event) {
     console.log('component is clicked');
     console.log(event);
  }
}

The actual problem is discussed in the May, 23rd release note of https://developers.google.com/android/guides/releases#may_23_2018

Basically, you need to bump all Play Services and Firebase libraries to their latest version (which may be different for each since version 15). You may use https://mvnrepository.com/ to find the latest version for each library.

MVW stands for Model-View-Whatever.

For completeness, here are all the acronyms mentioned:

MVC - Model-View-Controller

MVP - Model-View-Presenter

MVVM - Model-View-ViewModel

MVW / MV* / MVx - Model-View-Whatever

And some more:

HMVC - Hierarchical Model-View-Controller

MMV - Multiuse Model View

MVA - Model-View-Adapter

MVI - Model-View-Intent

Very easy trick is using a CSS calc formula. All modern browsers, IE9, wide range of mobile browsers should support this.

<div style='white-space:nowrap'>
  <span style='display:inline-block;width:80px;font-weight:bold'>
    <label for='field1'>Field1</label>
  </span>
  <input id='field1' name='field1' type='text' value='Some text' size='30' style='width:calc(100% - 80px)' />
</div>

PHP has a function called money_format for doing this. Read about this here.

I ran into this same problem, but in my case, the only thing that had changed is that I had uninstalled Visual Studio 2012 and installed Visual Studio 2013. I opened up our solution, but I kept getting the same The name 'model' does not exist in current context error in every Razor view.

My coworker suggested checking for updates for VS2013. After I installed the VS2013 Update 1, I stopped getting this error.

I want to mention one important note regarding req.query , because currently I am working on pagination functionality based on req.query and I have one interesting example to demonstrate to you...

Example:

// Fetching patients from the database
exports.getPatients = (req, res, next) => {

const pageSize = +req.query.pageSize;
const currentPage = +req.query.currentPage;

const patientQuery = Patient.find();
let fetchedPatients;

// If pageSize and currentPage are not undefined (if they are both set and contain valid values)
if(pageSize && currentPage) {
    /**
     * Construct two different queries 
     * - Fetch all patients 
     * - Adjusted one to only fetch a selected slice of patients for a given page
     */
    patientQuery
        /**
         * This means I will not retrieve all patients I find, but I will skip the first "n" patients
         * For example, if I am on page 2, then I want to skip all patients that were displayed on page 1,
         * 
         * Another example: if I am displaying 7 patients per page , I want to skip 7 items because I am on page 2,
         * so I want to skip (7 * (2 - 1)) => 7 items
         */
        .skip(pageSize * (currentPage - 1))

        /**
         * Narrow dont the amound documents I retreive for the current page
         * Limits the amount of returned documents
         * 
         * For example: If I got 7 items per page, then I want to limit the query to only
         * return 7 items. 
         */
        .limit(pageSize);
}
patientQuery.then(documents => {
    res.status(200).json({
        message: 'Patients fetched successfully',
        patients: documents
    });
  });
};

You will noticed + sign in front of req.query.pageSize and req.query.currentPage

Why? If you delete + in this case, you will get an error, and that error will be thrown because we will use invalid type (with error message 'limit' field must be numeric).

Important: By default if you extracting something from these query parameters, it will always be a string, because it's coming the URL and it's treated as a text.

If we need to work with numbers, and convert query statements from text to number, we can simply add a plus sign in front of statement.

Appending to the answer but using anonymous arrays and annotating:

Hash[*("a,b,c,d".split(',').zip([1,2,3,4]).flatten)]

Taking that answer apart, starting from the inside:

• "a,b,c,d" is actually a string.
• split on commas into an array.
• zip that together with the following array.
• [1,2,3,4] is an actual array.

The intermediate result is:

[[a,1],[b,2],[c,3],[d,4]]

flatten then transforms that to:

["a",1,"b",2,"c",3,"d",4]

and then:

*["a",1,"b",2,"c",3,"d",4] unrolls that into "a",1,"b",2,"c",3,"d",4

which we can use as the arguments to the Hash[] method:

Hash[*("a,b,c,d".split(',').zip([1,2,3,4]).flatten)]

which yields:

{"a"=>1, "b"=>2, "c"=>3, "d"=>4}

I found this solution on Mike Hike Hostetler's site that worked perfectly for me.

# rsync -avz -e "ssh -p $portNumber" user@remoteip:/path/to/files/ /local/path/

Setting an Initial Catalog allows you to set the database that queries run on that connection will use by default. If you do not set this for a connection to a server in which multiple databases are present, in many cases you will be required to have a USE statement in every query in order to explicitly declare which database you are trying to run the query on. The Initial Catalog setting is a good way of explicitly declaring a default database.

I assume that you haven't set the TableName property of the DataTable, for example via constructor:

var tbl = new DataTable("dtImage");

If you don't provide a name, it will be automatically created with "Table1", the next table will get "Table2" and so on.

Then the solution would be to provide the TableName and then check with Contains(nameOfTable).

To clarify it: You'll get an ArgumentException if that DataTable already belongs to the DataSet (the same reference). You'll get a DuplicateNameException if there's already a DataTable in the DataSet with the same name(not case-sensitive).

You can simplify your class code to this below and it will work as is but if you want to make your example work, add parenthesis at the end : string x = getTitle();

public class Pin
{
   public string Title { get; set;}
}

TL;DR; for Windows users:

(Quotation marks not needed if path has no blank spaces)

Git Bash: cd "/C/Program Files (x86)/Android" // macOS/Linux syntax

Cmd.exe: cd "C:\Program Files (x86)\Android" // windows syntax

When using git bash on windows, you have to:

• remove the colon after the drive letter
• replace your back-slashes with forward-slashes
• If you have blank spaces in your path: Put quotation marks at beginning and end of the path

Git Bash: cd "/C/Program Files (x86)/Android" // macOS/Linux syntax

Cmd.exe: cd "C:\Program Files (x86)\Android" // windows syntax

Use like this

<div ng-if="data.IsActive === 1">InActive</div>
<div ng-if="data.IsActive === 0">Active</div>

JavaScript Code

function ctrl($scope){
$scope.call={state:['second','first','nothing','Never', 'Gonna', 'Give', 'You', 'Up']}


$scope.whatClassIsIt= function(someValue){
     if(someValue=="first")
            return "ClassA"
     else if(someValue=="second")
         return "ClassB";
    else
         return "ClassC";
}
}

You can do the following to learn/test the concept:

1. Open new Excel Workbook and in Excel VBA editor right-click on Modules->Insert->Module

2. In newly added Module1 add the declaration; Public Global1 As String

3. in Worksheet VBA Module Sheet1(Sheet1) put the code snippet:

Sub setMe()
      Global1 = "Hello"
End Sub

4. in Worksheet VBA Module Sheet2(Sheet2) put the code snippet:

Sub showMe()
    Debug.Print (Global1)
End Sub

5. Run in sequence Sub setMe() and then Sub showMe() to test the global visibility/accessibility of the var Global1

Hope this will help.

I find, if the data is imported, you may need to use the trim command on top of it, to get your details. =LEFT(TRIM(B2),8) In my case, I was using it to find a IP range. 10.3.44.44 with mask 255.255.255.0, so response is: 10.3.44 Kind of handy.

    let timeStamp = dateFormatter.string(from: convertedDate!)

    return timeStamp
}

I used a very similar method to @bott, but I modified it a little bit to make there be no need to resize the image:

BufferedImage img = null;
try {
    img = ImageIO.read(new File("image.jpg"));
} catch (IOException e) {
    e.printStackTrace();
}
Image dimg = img.getScaledInstance(800, 508, Image.SCALE_SMOOTH);
ImageIcon imageIcon = new ImageIcon(dimg);
setContentPane(new JLabel(imageIcon));

Works every time. You can also get the width and height of the jFrame and use that in place of the 800 and 508 respectively.

Use the z modifier:

size_t x = ...;
ssize_t y = ...;
printf("%zu\n", x);  // prints as unsigned decimal
printf("%zx\n", x);  // prints as hex
printf("%zd\n", y);  // prints as signed decimal

So there are lots of useful solutions to the question - but which is fastest / uses the fewest resources?

Repeated tests using this frame:

/usr/bin/time bash -c 'a=two;b=onetwothree; x=100000; while [ $x -gt 0 ]; do TEST ; x=$(($x-1)); done'

Replacing TEST each time:

[[ $b =~ $a ]]           2.92 user 0.06 system 0:02.99 elapsed 99% CPU

[ "${b/$a//}" = "$b" ]   3.16 user 0.07 system 0:03.25 elapsed 99% CPU

[[ $b == *$a* ]]         1.85 user 0.04 system 0:01.90 elapsed 99% CPU

case $b in *$a):;;esac   1.80 user 0.02 system 0:01.83 elapsed 99% CPU

doContain $a $b          4.27 user 0.11 system 0:04.41 elapsed 99%CPU

(doContain was in F. Houri's answer)

And for giggles:

echo $b|grep -q $a       12.68 user 30.86 system 3:42.40 elapsed 19% CPU !ouch!

So the simple substitution option predictably wins whether in an extended test or a case. The case is portable.

Piping out to 100000 greps is predictably painful! The old rule about using external utilities without need holds true.

From the MSDN page:

OPENQUERY does not accept variables for its arguments

Fundamentally, this means you cannot issue a dynamic query. To achieve what your sample is attempting, try this:

SELECT * FROM 
   OPENQUERY([NameOfLinkedSERVER], 'SELECT * FROM TABLENAME') T1 
   INNER JOIN 
   MYSQLSERVER.DATABASE.DBO.TABLENAME T2 ON T1.PK = T2.PK 
where
   T1.field1 = @someParameter

Clearly if your TABLENAME table contains a large amount of data, this will go across the network too and performance might be poor. On the other hand, for a small amount of data, this works well and avoids the dynamic sql construction overheads (sql injection, escaping quotes) that an exec approach might require.

Use the below code for converting XML to JSON.

var json = new JavaScriptSerializer().Serialize(obj);

You can see the button "Code" in the attached screenshot, press it and you can get your code in many different languages including PHP cURL

The answers above pointed me in the right direction. Here is a generic version of what I got working:

  var script = document.createElement('script');
  script.src = 'http://' + location.hostname + '/module';
  script.addEventListener('load', postLoadFunction);
  document.head.appendChild(script);

  function postLoadFunction() {
     // add module dependent code here
  }      

You can't really do it the C way (I think) but a pythonic way of doing this would be (if your 'inputs' have spaces in between them):

raw_answer = raw_input()
answers = raw_answer.split(' ') # list of 'answers'

So you could rewrite your try to:

var1, var2 = raw_input("enter two numbers:").split(' ')

Note that this it somewhat less flexible than using the 'first' solution (for example if you add a space at the end this will already break).

Also be aware that var1 and var2 will still be strings with this method when not cast to int.

Here is what I ended up doing and it worked great.

First I moved the file input outside of the form so that it is not submitted:

<input name="imagefile[]" type="file" id="takePictureField" accept="image/*" onchange="uploadPhotos(\'#{imageUploadUrl}\')" />
<form id="uploadImageForm" enctype="multipart/form-data">
    <input id="name" value="#{name}" />
    ... a few more inputs ... 
</form>

Then I changed the uploadPhotos function to handle only the resizing:

window.uploadPhotos = function(url){
    // Read in file
    var file = event.target.files[0];

    // Ensure it's an image
    if(file.type.match(/image.*/)) {
        console.log('An image has been loaded');

        // Load the image
        var reader = new FileReader();
        reader.onload = function (readerEvent) {
            var image = new Image();
            image.onload = function (imageEvent) {

                // Resize the image
                var canvas = document.createElement('canvas'),
                    max_size = 544,// TODO : pull max size from a site config
                    width = image.width,
                    height = image.height;
                if (width > height) {
                    if (width > max_size) {
                        height *= max_size / width;
                        width = max_size;
                    }
                } else {
                    if (height > max_size) {
                        width *= max_size / height;
                        height = max_size;
                    }
                }
                canvas.width = width;
                canvas.height = height;
                canvas.getContext('2d').drawImage(image, 0, 0, width, height);
                var dataUrl = canvas.toDataURL('image/jpeg');
                var resizedImage = dataURLToBlob(dataUrl);
                $.event.trigger({
                    type: "imageResized",
                    blob: resizedImage,
                    url: dataUrl
                });
            }
            image.src = readerEvent.target.result;
        }
        reader.readAsDataURL(file);
    }
};

As you can see I'm using canvas.toDataURL('image/jpeg'); to change the resized image into a dataUrl adn then I call the function dataURLToBlob(dataUrl); to turn the dataUrl into a blob that I can then append to the form. When the blob is created, I trigger a custom event. Here is the function to create the blob:

/* Utility function to convert a canvas to a BLOB */
var dataURLToBlob = function(dataURL) {
    var BASE64_MARKER = ';base64,';
    if (dataURL.indexOf(BASE64_MARKER) == -1) {
        var parts = dataURL.split(',');
        var contentType = parts[0].split(':')[1];
        var raw = parts[1];

        return new Blob([raw], {type: contentType});
    }

    var parts = dataURL.split(BASE64_MARKER);
    var contentType = parts[0].split(':')[1];
    var raw = window.atob(parts[1]);
    var rawLength = raw.length;

    var uInt8Array = new Uint8Array(rawLength);

    for (var i = 0; i < rawLength; ++i) {
        uInt8Array[i] = raw.charCodeAt(i);
    }

    return new Blob([uInt8Array], {type: contentType});
}
/* End Utility function to convert a canvas to a BLOB      */

Finally, here is my event handler that takes the blob from the custom event, appends the form and then submits it.

/* Handle image resized events */
$(document).on("imageResized", function (event) {
    var data = new FormData($("form[id*='uploadImageForm']")[0]);
    if (event.blob && event.url) {
        data.append('image_data', event.blob);

        $.ajax({
            url: event.url,
            data: data,
            cache: false,
            contentType: false,
            processData: false,
            type: 'POST',
            success: function(data){
               //handle errors...
            }
        });
    }
});

Use [NSIndexPath indexPathForRow:inSection:] to quickly create an index path.

Edit: In Swift 3:

let indexPath = IndexPath(row: rowIndex, section: sectionIndex)

Swift 5

IndexPath(row: 0, section: 0)

The difference can be illustrated by the following:

std::cout << std::endl;

is equivalent to

std::cout << '\n' << std::flush;

So,

• Use std::endl If you want to force an immediate flush to the output.
• Use \n if you are worried about performance (which is probably not the case if you are using the << operator).

I use \n on most lines.
Then use std::endl at the end of a paragraph (but that is just a habit and not usually necessary).

Contrary to other claims, the \n character is mapped to the correct platform end of line sequence only if the stream is going to a file (std::cin and std::cout being special but still files (or file-like)).

To add to the answers above, while print can only take one parameter, it will allow for concatenation of multiple values, ie:

$count = 5;

print "This is " . $count . " values in " . $count/5 . " parameter";

This is 5 values in 1 parameter

This works for me with twitter bootstrap 2 and simple_form 2.0.4
Result is a span6 text area in a span9 row

 <div class="row" >
   <div class="span9">
     <%= f.input :some_text, :input_html => {:rows => 5, :placeholder => "Enter some text.", :class => "span6"}%>
   </div>
 </div>

In an angular-cli environment, the most straightforward way I've found is the following:

1. Solution in an environment with s_c_s_s_ stylesheets

npm install bootstrap-sass —save

In style.scss:

$icon-font-path: '~bootstrap-sass/assets/fonts/bootstrap/';
@import '~bootstrap-sass/assets/stylesheets/bootstrap';

Note1: The ~ character is a reference to nodes_modules folder.
Note2: As we are using scss, we can customize all boostrap variables we want.

2. Solution in an environment with c_s_s_ stylesheets

npm install bootstrap —save

In style.css:

@import '~bootstrap/dist/css/bootstrap.css';

You can also use between:

df[df.some_date.between(start_date, end_date)]

It can be that your resources directory is not added to classpath when creating a project via Spring Initializr. So your application is never loading the application.properties file that you have configured.

To make a quick test if this is the case, add the following to your application.properties file:

server.port=8081

Now when running your application you should see in the spring boot console output something like this:

INFO  o.s.b.w.e.tomcat.TomcatWebServer - Tomcat started on port(s): **8081** (http) with context path ''

If your port is still default 8080 and not changed to 8081, your application.properties files is obviously not loading.

You can also check if your application runs with gradle bootRun from command line. Which most likely will be work.

Solution:

1. Close IntelliJ, then inside your project folder delete the ".idea" folder
2. Reimport your project to IntelliJ like following: "Import Project" -> "select ONLY your build.gradle file to import". (IntelliJ will automatically grab the rest)
3. build and run your application again

See official answer by IntelliJ Support: IDEA-221673

In Linux Mint, and most likely Ubuntu, you can try "nvidia-smi --loop=1"

if($("input:radio[name=test]").is(":checked")){
  //Code to append goes here
}

json.loads & ast.literal_eval seems to be working but simple list within config is treating each character as byte so returning even square bracket....

meaning if config has fieldvalue = [1,2,3,4,5]

then config.read(*.cfg) config['fieldValue'][0] returning [ in place of 1

It's worth noting that the QuerySet.values_list() method doesn't actually return a list, but an object of type django.db.models.query.ValuesListQuerySet, in order to maintain Django's goal of lazy evaluation, i.e. the DB query required to generate the 'list' isn't actually performed until the object is evaluated.

Somewhat irritatingly, though, this object has a custom __repr__ method which makes it look like a list when printed out, so it's not always obvious that the object isn't really a list.

The exception in the question is caused by the fact that custom objects cannot be serialized in JSON, so you'll have to convert it to a list first, with...

my_list = list(self.get_queryset().values_list('code', flat=True))

...then you can convert it to JSON with...

json_data = json.dumps(my_list)

You'll also have to place the resulting JSON data in an HttpResponse object, which, apparently, should have a Content-Type of application/json, with...

response = HttpResponse(json_data, content_type='application/json')

...which you can then return from your function.

For alphabetical order following nationalization, use Collator.

//Get the Collator for US English and set its strength to PRIMARY
Collator usCollator = Collator.getInstance(Locale.US);
usCollator.setStrength(Collator.PRIMARY);
if( usCollator.compare("abc", "ABC") == 0 ) {
    System.out.println("Strings are equivalent");
}

For a list of supported locales, see JDK 8 and JRE 8 Supported Locales.

you cannot use curl in certain servers u can use this code

<?php
$url = 'http://www.example.com';
$array = get_headers($url);
$string = $array[0];
if(strpos($string,"200"))
  {
    echo 'url exists';
  }
  else
  {
    echo 'url does not exist';
  }
?>

Another option is to run the html through a text based web browser and dump it. For example (using Lynx):

lynx -dump html_to_convert.html > converted_html.txt

This can be done within a python script as follows:

import subprocess

with open('converted_html.txt', 'w') as outputFile:
    subprocess.call(['lynx', '-dump', 'html_to_convert.html'], stdout=testFile)

It won't give you exactly just the text from the HTML file, but depending on your use case it may be preferable to the output of html2text.

C++ provides a good mechanism to manage the life time of an object though class/struct constructs. This is one of the best features of C++ over other languages.

When you have member variables exposed through ref or pointer it violates the encapsulation in principle. This idiom enables the consumer of the class to change the state of an object of A without it(A) having any knowledge or control of it. It also enables the consumer to hold on to a ref/pointer to A's internal state, beyond the life time of the object of A. This is bad design. Instead the class could be refactored to hold a ref/pointer to the shared object (not own it) and these could be set using the constructor (Mandate the life time rules). The shared object's class may be designed to support multithreading/concurrency as the case may apply.

EcmaScript 2017 introduced Object.entries that allows you to iterate over values and keys. Documentation

var map = { key1 : 'value1', key2 : 'value2' }

for (let [key, value] of Object.entries(map)) {
    console.log(`${key}: ${value}`);
}

The result will be:

key1: value1
key2: value2

This is the complete basic structure for 100% width layout in Bootstrap v3.0.0. You shouldn't wrap your <div class="row"> with container class. Cause container class will take lots of margin and this will not provide you full screen (100% width) layout where bootstrap has removed container-fluid class from their mobile-first version v3.0.0.

So just start writing <div class="row"> without container class and you are ready to go with 100% width layout.

You can try something like this:

      logo.ScaleAbsolute(500, 300)

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

Adding one more approach :

value = $(this).val().toLowerCase();
$("#product-search-result tr").filter(function () {
$(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)
});

Yes it is possible. You need one ON for each join table.

LEFT JOIN ab
  ON ab.sht = cd.sht
LEFT JOIN aa
  ON aa.sht = cd.sht

Incidentally my personal formatting preference for complex SQL is described in http://bentilly.blogspot.com/2011/02/sql-formatting-style.html. If you're going to be writing a lot of this, it likely will help.

If you want to get complete ContainerId based on Container name then use following command

 docker ps --no-trunc -aqf name=containername

This might be what you are looking for:

<?php

$text = 'This is a Simple text.';

// this echoes "is is a Simple text." because 'i' is matched first
echo strpbrk($text, 'mi');

// this echoes "Simple text." because chars are case sensitive
echo strpbrk($text, 'S');
?>

Is it?

Or maybe this:

<?php
$mystring = 'abc';
$findme   = 'a';
$pos = strpos($mystring, $findme);

// Note our use of ===.  Simply == would not work as expected
// because the position of 'a' was the 0th (first) character.
if ($pos === false) {
    echo "The string '$findme' was not found in the string '$mystring'";
} else {
    echo "The string '$findme' was found in the string '$mystring'";
    echo " and exists at position $pos";
}
?>

Or even this

<?php
$email  = '[email protected]';
$domain = strstr($email, '@');
echo $domain; // prints @example.com

$user = strstr($email, '@', true); // As of PHP 5.3.0
echo $user; // prints name
?>

You can read all about them in the documentation here:

Json.NET - Documentation

http://james.newtonking.com/json/help/index.html?topic=html/SelectToken.htm

Interpretation for the author

var o = JObject.Parse(response);
var a = o.SelectToken("data").Select(jt => jt.ToObject<TheUser>()).ToList();

You should use return as in:

function refreshGrid(entity) {
  var store = window.localStorage;
  var partitionKey;
  if (exit) {
    return;
  }

On the model set $incrementing to false

public $incrementing = false;

This will stop it from thinking it is an auto increment field.

If you are looking for readability, I believe that this is that code:

print '%(kg).2f kg = %(lb).2f lb = %(gal).2f gal = %(l).2f l' % {
    'kg': var1,
    'lb': var2,
    'gal': var3,
    'l': var4,
}

Instead of .First() change it to .FirstOrDefault()

Above answers are also correct. I just want to give a brief that there's two ways to hide the keyboard when starting the activity, from manifest.xml. eg:

<activity
..........
android:windowSoftInputMode="stateHidden"
..........
/>

• The above way always hide it when entering the activity.

or

<activity
..........
android:windowSoftInputMode="stateUnchanged"
..........
/>

• This one says don't change it (e.g. don't show it if it isn't already shown, but if it was open when entering the activity, leave it open).

You didn't use FROM expression for a table

SELECT DISTINCT Description, Date as treatmentDate
**FROM <A TABLE>**
WHERE doothey.Patient P, doothey.Account A, doothey.AccountLine AL, doothey.Item.I
AND P.PatientID = A.PatientID
AND A.AccountNo = AL.AccountNo
AND AL.ItemNo = I.ItemNo
AND (p.FamilyName = 'Stange' AND p.GivenName = 'Jessie');

I had the same issue and managed to resolve it eventually. In my case, the port that the client sends the request to did not have a SSL cert binding to it. So I fixed the issue by binding a SSL cert to the port on the server side. Once that was done, this exception went away.

If anyone has this issue when building a Maven project created in IntelliJ IDEA externally, I used the following dependency instead of the answer:

<dependency>
  <groupId>org.jetbrains</groupId>
  <artifactId>annotations</artifactId>
  <version>15.0</version>
</dependency>

Using this will allow the project to build on IntelliJ IDEA and by itself using Maven.

You can find it here.

I'm suspicious of the ActiveFileName property. According to the log4j javadoc, there isn't such a property on the TimeBasedRollingPolicy class. (No setActiveFileName or getActiveFileName methods.)

I don't know what specifying an unknown property would do, but it is possible that it will cause the containing object to be abandoned, and that could lead to the warnings that you saw.

Try leaving it out and seeing what happens.

According to w3.org (note that this link is in the long-expired draft HTML 3.0 spec):

An unordered list typically is a bulleted list of items. HTML 3.0 gives you the ability to customise the bullets, to do without bullets and to wrap list items horizontally or vertically for multicolumn lists.

The opening list tag must be <UL>. It is followed by an optional list header (<LH>caption</LH>) and then by the first list item (<LI>). For example:

<UL>
  <LH>Table Fruit</LH>
  <LI>apples
  <LI>oranges
  <LI>bananas
</UL>

which could be rendered as:

Table Fruit

• apples
• oranges
• bananas

Note: Some legacy documents may include headers or plain text before the first LI element. Implementors of HTML 3.0 user agents are advised to cater for this possibility in order to handle badly formed legacy documents.

Here is some workaround that actually worked for me, it is the same solution as in the most popular answer - just add hw.keyboard=yes to config.ini but since this didn't work for me I additionally

1. renamed config.ini (any name will do) to something like consssssfig.ini
2. restarted emulator (obviously it didn't start)
3. renamed config.ini back again
4. (I am not sure if relevant) I added this new parameter (hw.keyboard=yes) at the beggining of config.ini file

If you load a page in your browser using HTTPS, the browser will refuse to load any resources over HTTP. As you've tried, changing the API URL to have HTTPS instead of HTTP typically resolves this issue. However, your API must not allow for HTTPS connections. Because of this, you must either force HTTP on the main page or request that they allow HTTPS connections.

Note on this: The request will still work if you go to the API URL instead of attempting to load it with AJAX. This is because the browser is not loading a resource from within a secured page, instead it's loading an insecure page and it's accepting that. In order for it to be available through AJAX, though, the protocols should match.

Apache HttpComponents. The examples for the two modules - HttpCore and HttpClient will get you started right away.

Not that HttpUrlConnection is a bad choice, HttpComponents will abstract a lot of the tedious coding away. I would recommend this, if you really want to support a lot of HTTP servers/clients with minimum code. By the way, HttpCore could be used for applications (clients or servers) with minimum functionality, whereas HttpClient is to be used for clients that require support for multiple authentication schemes, cookie support etc.

ws2s project is aimed at bring socket to browser-side js. It is a websocket server which transform websocket to socket.

You can select directly into the variable rather than using set:

DECLARE @times int

SELECT @times = COUNT(DidWin)
FROM thetable
WHERE DidWin = 1 AND Playername='Me'

If you need to set multiple variables you can do it from the same select (example a bit contrived):

DECLARE @wins int, @losses int

SELECT @wins = SUM(DidWin), @losses = SUM(DidLose)
FROM thetable
WHERE Playername='Me'

If you are partial to using set, you can use parentheses:

DECLARE @wins int, @losses int

SET (@wins, @losses) = (SELECT SUM(DidWin), SUM(DidLose)

I had a need for an extended version of this: instead of embedding a single number in a string, I needed to generate a series of file names of the form 'file1.pdf', 'file2.pdf' etc. This is how it worked:

['file' + str(i) + '.pdf' for i in range(1,4)]

On Linux systems and OS X, the character to input to cause an EOF is Ctrl-D. For Windows, it's Ctrl-Z.

Depending on the operating system, this character will only work if it's the first character on a line, i.e. the first character after an Enter. Since console input is often line-oriented, the system may also not recognize the EOF character until after you've followed it up with an Enter.

And yes, if that character is recognized as an EOF, then your program will never see the actual character. Instead, a C program will get a -1 from getchar().

Swift 1.2 and iOS 8

Create custom directory (name = "MyCustomData") inside the documents directory but only if the directory does not exist.

// path to documents directory
let documentDirectoryPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true).first as! String

// create the custom folder path
let myCustomDataDirectoryPath = documentDirectoryPath.stringByAppendingPathComponent("/MyCustomData")

// check if directory does not exist
if NSFileManager.defaultManager().fileExistsAtPath(myCustomDataDirectoryPath) == false {

    // create the directory
    var createDirectoryError: NSError? = nil
    NSFileManager.defaultManager().createDirectoryAtPath(myCustomDataDirectoryPath, withIntermediateDirectories: false, attributes: nil, error: &createDirectoryError)

    // handle the error, you may call an exception
    if createDirectoryError != nil {
        println("Handle directory creation error...")
    }

}

Update for Angular 2 final version

In app.module.ts:

• Add imports:

    import { HashLocationStrategy, LocationStrategy } from '@angular/common';
  

• And in NgModule provider, add:

    {provide: LocationStrategy, useClass: HashLocationStrategy}
  

Example (app.module.ts):

import { NgModule }       from '@angular/core';
import { BrowserModule  } from '@angular/platform-browser';
import { AppComponent }   from './app.component';
import { HashLocationStrategy, LocationStrategy } from '@angular/common';

@NgModule({
    declarations: [AppComponent],
    imports: [BrowserModule],
    providers: [{provide: LocationStrategy, useClass: HashLocationStrategy}],
    bootstrap: [AppComponent],
})
export class AppModule {}

Alternative

Use RouterModule.forRoot with the {useHash: true} argument.

Example:(from angular docs)

import { NgModule } from '@angular/core';
...

const routes: Routes = [//routes in here];

@NgModule({
  imports: [
    BrowserModule,
    FormsModule,
    RouterModule.forRoot(routes, { useHash: true })
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

There are a few possibilities:

1. Your workstation doesn't have the root CA cert used to sign your server's cert. How exactly you fix that depends on what OS you're running and what release, etc. (I suspect this is not related)
2. Your cert isn't installed properly. If your SSL cert requires an intermediate cert to be presented and you didn't set that up, you can get these warnings.
3. Are you sure you've enabled SSL on port 443?

For starters, to eliminate (3), what happens if you telnet to that port?

Assuming it's not (3), then depending on your needs you may be fine with ignoring these errors and just passing --no-certificate-check. You probably want to use a regular browser (which generally will bundle the root certs directly) and see if things are happy.

If you want to manually verify the cert, post more details from the openssl s_client output. Or use openssl x509 -text -in /path/to/cert to print it out to your terminal.

I had the same issue with my system, I removed the JavaScript code from the of my page and put it at body just before closing body tag

If you'd like to add text at the end of each line in-place (in the same file), you can use -i parameter, for example:

sed -i'.bak' 's/$/:80/' foo.txt

However -i option is non-standard Unix extension and may not be available on all operating systems.

So you can consider using ex (which is equivalent to vi -e/vim -e):

ex +"%s/$/:80/g" -cwq foo.txt

which will add :80 to each line, but sometimes it can append it to blank lines.

So better method is to check if the line actually contain any number, and then append it, for example:

ex  +"g/[0-9]/s/$/:80/g" -cwq foo.txt

If the file has more complex format, consider using proper regex, instead of [0-9].

No, there is no "easy" way. Your best bet would be to do a loop where you first check each previous sibling, then move to the parent node and all of its previous siblings.

You'll need to break the selector into two, 1 to check if the current node could be the top level node in your selector, and 1 to check if it's descendants match.

Edit: This might as well be a plugin. You can use this with any selector in any HTML:

(function($) {
    $.fn.closestPrior = function(selector) {
        selector = selector.replace(/^\s+|\s+$/g, "");
        var combinator = selector.search(/[ +~>]|$/);
        var parent = selector.substr(0, combinator);
        var children = selector.substr(combinator);
        var el = this;
        var match = $();
        while (el.length && !match.length) {
            el = el.prev();
            if (!el.length) {
                var par = el.parent();
                // Don't use the parent - you've already checked all of the previous 
                // elements in this parent, move to its previous sibling, if any.
                while (par.length && !par.prev().length) {
                    par = par.parent();
                }
                el = par.prev();
                if (!el.length) {
                    break;
                }
            }
            if (el.is(parent) && el.find(children).length) {
                match = el.find(children).last();
            }
            else if (el.find(selector).length) {
                match = el.find(selector).last();
            }
        }
        return match;
    }
})(jQuery);

I tried the accepted answer which prevented the body from scrolling but had the issue of scrolling to the top. This should solve both issues.

As a side note, it appears overflow:hidden doesn't work on body for iOS Safari only as iOS Chrome works fine.

var scrollPos = 0;

$('.modal')
    .on('show.bs.modal', function (){
        scrollPos = $('body').scrollTop();
        $('body').css({
            overflow: 'hidden',
            position: 'fixed',
            top : -scrollPos
        });
    })
    .on('hide.bs.modal', function (){
        $('body').css({
            overflow: '',
            position: '',
            top: ''
        }).scrollTop(scrollPos);
    });

There is a new API that makes this even simpler.

plt.gca().invert_xaxis()

and/or

plt.gca().invert_yaxis()

console.log(document.getElementById('xx') ) evaluates to null.

document.getElementById('xx') !=null evaluates to false

You should use document.getElementById('xx') !== null as it is a stronger equality check.

This works with all DBRM/SQL, it is standard ANSI:

SELECT *
  FROM owner.tablename A
 WHERE condition
  AND  n+1 <= (
         SELECT COUNT(DISTINCT b.column_order)
           FROM owner.tablename B
          WHERE condition
            AND b.column_order>a.column_order
          )
ORDER BY a.column_order DESC

I saw this question a lot when I worked for an address verification company. I'm posting the answer here to make it more accessible to programmers searching around with the same question. The company I was at processed billions of addresses, and we learned a lot in the process.

First, we need to understand a few things about addresses.

Addresses are not regular

This means that regular expressions are out. I've seen it all, from simple regular expressions that match addresses in a very specific format, to this:

/\s+(\d{2,5}\s+)(?![a|p]m\b)(([a-zA-Z|\s+]{1,5}){1,2})?([\s|,|.]+)?(([a-zA-Z|\s+]{1,30}){1,4})(court|ct|street|st|drive|dr|lane|ln|road|rd|blvd)([\s|,|.|;]+)?(([a-zA-Z|\s+]{1,30}){1,2})([\s|,|.]+)?\b(AK|AL|AR|AZ|CA|CO|CT|DC|DE|FL|GA|GU|HI|IA|ID|IL|IN|KS|KY|LA|MA|MD|ME|MI|MN|MO|MS|MT|NC|ND|NE|NH|NJ|NM|NV|NY|OH|OK|OR|PA|RI|SC|SD|TN|TX|UT|VA|VI|VT|WA|WI|WV|WY)([\s|,|.]+)?(\s+\d{5})?([\s|,|.]+)/i

... to this where a 900+ line-class file generates a supermassive regular expression on the fly to match even more. I don't recommend these (for example, here's a fiddle of the above regex, that makes plenty of mistakes). There isn't an easy magic formula to get this to work. In theory and by theory, it's impossible to match addresses with a regular expression.

USPS Publication 28 documents the many formats of addresses that are possible, with all their keywords and variations. Worst of all, addresses are often ambiguous. Words can mean more than one thing ("St" can be "Saint" or "Street"), and there are words that I'm pretty sure they invented. (Who knew that "Stravenue" was a street suffix?)

You'd need some code that really understands addresses, and if that code does exist, it's a trade secret. But you could probably roll your own if you're really into that.

Addresses come in unexpected shapes and sizes

Here are some contrived (but complete) addresses:

1)  102 main street
    Anytown, state

2)  400n 600e #2, 52173

3)  p.o. #104 60203

Even these are possibly valid:

4)  829 LKSDFJlkjsdflkjsdljf Bkpw 12345

5)  205 1105 14 90210

Obviously, these are not standardized. Punctuation and line break are not guaranteed. Here's what's going on:

1. Number 1 is complete because it contains a street address and a city and state. With that information, there's enough to identify the address, and it can be considered "deliverable" (with some standardization).

2. Number 2 is complete because it contains a street address (with secondary/unit number) and a 5-digit ZIP code, which is enough to identify an address.

3. Number 3 is a complete post office box format, as it contains a ZIP code.

4. Number 4 is also complete because the ZIP code is unique, meaning that a private entity or corporation has purchased that address space. A unique ZIP code is for high-volume or concentrated delivery spaces. Anything addressed to ZIP code 12345 goes to General Electric in Schenectady, NY. This example won't reach anyone in particular, but the USPS would still deliver it.

5. Number 5 is also complete, believe it or not. With just those numbers, the full address can be discovered when parsed against a database of all possible addresses. Filling in the missing directionals, secondary designator, and ZIP+4 code is trivial when you see each number as a component. Here's what it looks like, fully expanded and standardized:

205 N 1105 W Apt 14

Beverly Hills CA 90210-5221

Address data is not your own

In most countries that provide official address data to licensed vendors, the address data itself belongs to the governing agency. In the US, the USPS owns the addresses. The same is true for Canada Post, Royal Mail, and others, though each country enforces or defines ownership a little differently. Knowing this is important since it usually forbids reverse-engineering the address database. You have to be careful how to acquire, store, and use the data.

Google Maps is a common go-to for quick address fixes, but the TOS is rather prohibitive; for example, you can't use their data or APIs without showing a Google Map, and for non-commercial purposes only (unless you pay), and you can't store the data (except for temporary caching). Makes sense. Google's data is some of the best in the world. However, Google Maps does not verify the address. If an address does not exist, it will still show you where the address would be if it did exist (try it on your own street; use a house number that you know doesn't exist). This is useful sometimes, but be aware of that.

Nominatim's usage policy is similarly limiting, especially for high volume and commercial use, and the data is mostly drawn from free sources, so it isn't as well maintained (such as the nature of open projects). However, this may still suit your needs. A great community supports it.

The USPS itself has an API, but it goes down a lot and comes with no guarantees nor support. It might also be hard to use. Some people use it sparingly with no problems. But it's easy to miss that the USPS requires that you use their API only for confirming addresses to ship through them.

People expect addresses to be hard

Unfortunately, we've conditioned our society to expect addresses to be complicated. There are dozens of good UX articles all over the Internet about this. Still, the fact is, if you have an address form with individual fields, that's what users expect, even though it makes it harder for edge-case addresses that don't fit the format the form is expecting, or maybe the form requires a field it shouldn't. Or users don't know where to put a certain part of their address.

I could go on and on about the bad UX of checkout forms these days, but instead, I'll say that combining the addresses into a single field will be a welcome change -- people will be able to type their address how they see fit, rather than trying to figure out your lengthy form. However, this change will be unexpected and users may find it a little jarring at first. Just be aware of that.

Part of this pain can be alleviated by putting the country field out front, before the address. When they fill out the country field first, you know how to make your form appear. Maybe you have a good way to deal with single-field US addresses, so if they select the United States, you can reduce your form to a single field, otherwise show the component fields. Just things to think about!

Now we know why it's hard; what can you do about it?

The USPS licenses vendors through a process called CASS™ Certification to provide verified addresses to customers. These vendors have access to the USPS database, updated monthly. Their software must conform to rigorous standards to be certified, and they don't often require agreement to such limiting terms as discussed above.

Many CASS-Certified companies can process lists or have APIs: Melissa Data, Experian QAS, and SmartyStreets, to name a few.

(Due to getting flak for "advertising," I've truncated my answer at this point. It's up to you to find a solution that works for you.)

The Truth: Really, folks, I don't work at any of these companies. It's not an advertisement.

I had the same problem I installed NetBeans 8.2 on macOS High Sierra, and by default settings, NetBeans will work with the latest JDK release (currently JDK 9).

What I did was forcing NetBeans to use JDK 8, you must config your netbeans.conf file, you can find it on:

/Applications/NetBeans/NetBeans 8.2.app/Contents/Resources/NetBeans/etc/netbeans.conf

You need to uncomment and update your path to JDK, you will find yours at:

/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home

Just save it, restart NetBeans and you are done!

If you save the excel file as a CSV file then you can import it into a mysql database using tools such as PHPMyAdmin

Im not sure if this would help in your situation, but a csv file either manually or programatically would be a lot easier to parse into a database than an excel file I would have thought.

EDIT: I would however suggest looking at the other answers rather than mine since @diEcho answer seems more appropriate.

For android, Use: https://developer.android.com/reference/android/net/Uri#buildUpon()

URI oldUri = new URI(uri);
Uri.Builder builder = oldUri.buildUpon();
 builder.appendQueryParameter("newParameter", "dummyvalue");
 Uri newUri =  builder.build();

You want something like:

<appSettings>
  <add key="developmentModeUserId" xdt:Transform="Remove" xdt:Locator="Match(key)"/>
  <add key="developmentMode" value="false" xdt:Transform="SetAttributes"
          xdt:Locator="Match(key)"/>
</appSettings>

I added an extension to Exception which returns the line, column, method, filename and message:

public static class Extensions
{
    public static string ExceptionInfo(this Exception exception)
    {

        StackFrame stackFrame = (new StackTrace(exception, true)).GetFrame(0);
        return string.Format("At line {0} column {1} in {2}: {3} {4}{3}{5}  ",
           stackFrame.GetFileLineNumber(), stackFrame.GetFileColumnNumber(),
           stackFrame.GetMethod(), Environment.NewLine, stackFrame.GetFileName(),
           exception.Message);

    }
}

I'm adding this answer not because it's likely to be helpful but just because it's true.

In addition to using the existing answers explaining how to make more than one translation by chaining them, you can also construct the 4x4 matrix yourself

I grabbed the following image from some random site I found while googling which shows rotational matrices:

Rotation around x axis:
Rotation around y axis:
Rotation around z axis:

I couldn't find a good example of translation, so assuming I remember/understand it right, translation:

[1 0 0 0]
[0 1 0 0]
[0 0 1 0]
[x y z 1]

See more at the Wikipedia article on transformation as well as the Pragamatic CSS3 tutorial which explains it rather well. Another guide I found which explains arbitrary rotation matrices is Egon Rath's notes on matrices

Matrix multiplication works between these 4x4 matrices of course, so to perform a rotation followed by a translation, you make the appropriate rotation matrix and multiply it by the translation matrix.

This can give you a bit more freedom to get it just right, and will also make it pretty much completely impossible for anyone to understand what it's doing, including you in five minutes.

But, you know, it works.

Edit: I just realized that I missed mentioning probably the most important and practical use of this, which is to incrementally create complex 3D transformations via JavaScript, where things will make a bit more sense.

I would suggest everytime when using global check if the variable is already define by simply check

if (!global.logger){
  global.logger = require('my_logger');
}

I've found it to have better performance

Use this:

SELECT * 
FROM tablename 
ORDER BY priority desc, FIELD(name, "core")

You can enable pretty-printing by setting the SerializationFeature.INDENT_OUTPUT on your ObjectMapper like so:

mapper.enable(SerializationFeature.INDENT_OUTPUT);

Just in case someone looking for a solution to this for a Windows based system or NAS:

There is a built-in function in Windows that shows you what files on the local computer are open/locked by remote computer (which has the file open through a file share):

• Select "Manage Computer" (Open "Computer Management")
• click "Shared Folders"
• choose "Open Files"

There you can even close the file forcefully.

To set the password, edit your redis.conf file, find this line

# requirepass foobared

Then uncomment it and change foobared to your password. Make sure you choose something pretty long, 32 characters or so would probably be good, it's easy for an outside user to guess upwards of 150k passwords a second, as the notes in the config file mention.

To authenticate with your new password using predis, the syntax you have shown is correct. Just add password as one of the connection parameters.

To shut down redis... check in your config file for the pidfile setting, it will probably be

pidfile /var/run/redis.pid

From the command line, run:

cat /var/run/redis.pid

That will give you the process id of the running server, then just kill the process using that pid:

kill 3832

Update

I also wanted to add, you could also make the /etc/init.d/redis-server stop you're used to work on your live server. All those files in /etc/init.d/ are just shell scripts, take the redis-server script off your local server, and copy it to the live server in the same location, and then just look what it does with vi or whatever you like to use, you may need to modify some paths and such, but it should be pretty simple.

Paste this on your command line:

export LC_CTYPE="en_US.UTF-8" 

If you prefer shorter if else statement, you can use this shorthand:

<%= typeof(id)!== 'undefined' ?  id : '' %>

It means display the id if is valid and blank if it wasn't.

Comments work fine in any of the usual Java/Groovy forms, but you can't currently use groovydoc to process your Jenkinsfile (s).

First, groovydoc chokes on files without extensions with the wonderful error

... and second, as far as I can tell Javadoc-style commments at the start of a groovy script are ignored. So even if you copy/rename your Jenkinsfile to Jenkinsfile.groovy, you won't get much useful output.

I want to be able to use a

/**
 * Document my Jenkinsfile's overall purpose here
 */

comment at the start of my Jenkinsfile. No such luck (yet).

groovydoc will process classes and methods defined in your Jenkinsfile if you pass -private to the command, though.

Use ThenByDescending:

var hold = MyList.OrderBy(x => x.StartDate)
                 .ThenByDescending(x => x.EndDate)
                 .ToList();

You can also use query syntax and say:

var hold = (from x in MyList
           orderby x.StartDate, x.EndDate descending
           select x).ToList();

ThenByDescending is an extension method on IOrderedEnumerable which is what is returned by OrderBy. See also the related method ThenBy.

Can someone please tell me how to create a static library from a .cpp and a .hpp file? Do I need to create the .o and the the .a?

Yes.

Create the .o (as per normal):

g++ -c header.cpp

Create the archive:

ar rvs header.a header.o

Test:

g++ test.cpp header.a -o executable_name

Note that it seems a bit pointless to make an archive with just one module in it. You could just as easily have written:

g++ test.cpp header.cpp -o executable_name

Still, I'll give you the benefit of the doubt that your actual use case is a bit more complex, with more modules.

Hope this helps!

You need to check out the attr method in the jQuery docs. You are misusing it. What you are doing within the if statements simply replaces all image tags src with the string specified in the 2nd parameter.

http://api.jquery.com/attr/

A better way to approach replacing a series of images source would be to loop through each and check it's source.

Example:

$('img').each(function () {

Yes. Or, rather, no.

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

UPDATE:

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

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

I'm not sure why Gabriel Silveira wrote the function that way but a simpler form that works for me just as well and without the minification is:

Array.prototype.unique = function() {
  return this.filter(function(value, index, array) {
    return array.indexOf(value, index + 1) < 0;
  });
};

or in CoffeeScript:

Array.prototype.unique = ->
  this.filter( (value, index, array) ->
    array.indexOf(value, index + 1) < 0
  )

To start, I would suggest to test whether there is a problem between your application and its dependencies using dependency walker

The alternative for deep copying objects having nested objects inside is by using lodash's cloneDeep method.

For Angular, you can do it like this:

Install lodash with yarn add lodash or npm install lodash.

In your component, import cloneDeep and use it:

import { cloneDeep } from "lodash";
...
clonedObject = cloneDeep(originalObject);

It's only 18kb added to your build, well worth for the benefits.

I've also written an article here, if you need more insight on why using lodash's cloneDeep.

You need to use the cURL library to send this request.

<?php
// Your ID and token
$blogID = '8070105920543249955';
$authToken = 'OAuth 2.0 token here';

// The data to send to the API
$postData = array(
    'kind' => 'blogger#post',
    'blog' => array('id' => $blogID),
    'title' => 'A new post',
    'content' => 'With <b>exciting</b> content...'
);

// Setup cURL
$ch = curl_init('https://www.googleapis.com/blogger/v3/blogs/'.$blogID.'/posts/');
curl_setopt_array($ch, array(
    CURLOPT_POST => TRUE,
    CURLOPT_RETURNTRANSFER => TRUE,
    CURLOPT_HTTPHEADER => array(
        'Authorization: '.$authToken,
        'Content-Type: application/json'
    ),
    CURLOPT_POSTFIELDS => json_encode($postData)
));

// Send the request
$response = curl_exec($ch);

// Check for errors
if($response === FALSE){
    die(curl_error($ch));
}

// Decode the response
$responseData = json_decode($response, TRUE);

// Close the cURL handler
curl_close($ch);

// Print the date from the response
echo $responseData['published'];

If, for some reason, you can't/don't want to use cURL, you can do this:

<?php
// Your ID and token
$blogID = '8070105920543249955';
$authToken = 'OAuth 2.0 token here';

// The data to send to the API
$postData = array(
    'kind' => 'blogger#post',
    'blog' => array('id' => $blogID),
    'title' => 'A new post',
    'content' => 'With <b>exciting</b> content...'
);

// Create the context for the request
$context = stream_context_create(array(
    'http' => array(
        // http://www.php.net/manual/en/context.http.php
        'method' => 'POST',
        'header' => "Authorization: {$authToken}\r\n".
            "Content-Type: application/json\r\n",
        'content' => json_encode($postData)
    )
));

// Send the request
$response = file_get_contents('https://www.googleapis.com/blogger/v3/blogs/'.$blogID.'/posts/', FALSE, $context);

// Check for errors
if($response === FALSE){
    die('Error');
}

// Decode the response
$responseData = json_decode($response, TRUE);

// Print the date from the response
echo $responseData['published'];

You are testing against the string minus the last character:

>>> '"xxx"'[:-1]
'"xxx'

Note how the last character, the ", is not part of the output of the slice.

I think you wanted just to test against the last character; use [-1:] to slice for just the last element.

However, there is no need to slice here; just use str.startswith() and str.endswith() directly.

let string2 = " there"
var instruction = "look over"

choice 1 :

 instruction += string2;

  println(instruction)

choice 2:

 var Str = instruction + string2;

 println(Str)

I needed a dropdown in a editable grid myself with preselected dropdown values. Afaik, the selectlist data is provided by the controller to the view, so it is created before the view consumes it. Once the view consumes the SelectList, I hand it over to a custom helper that uses the standard DropDownList helper. So, a fairly light solution imo. Guess it fits in the ASP.Net MVC spirit at the time of writing; when not happy roll your own...

public static string DropDownListEx(this HtmlHelper helper, string name, SelectList selectList, object selectedValue)
{
    return helper.DropDownList(name, new SelectList(selectList.Items, selectList.DataValueField, selectList.DataTextField, selectedValue));
}

using System.Diagnostics;

class Program
{
    static void Main()
    {
        Process.Start("C:\\");
    }
}

If your application needs cmd arguments, use something like this:

using System.Diagnostics;

class Program
{
    static void Main()
    {
        LaunchCommandLineApp();
    }

    /// <summary>
    /// Launch the application with some options set.
    /// </summary>
    static void LaunchCommandLineApp()
    {
        // For the example
        const string ex1 = "C:\\";
        const string ex2 = "C:\\Dir";

        // Use ProcessStartInfo class
        ProcessStartInfo startInfo = new ProcessStartInfo();
        startInfo.CreateNoWindow = false;
        startInfo.UseShellExecute = false;
        startInfo.FileName = "dcm2jpg.exe";
        startInfo.WindowStyle = ProcessWindowStyle.Hidden;
        startInfo.Arguments = "-f j -o \"" + ex1 + "\" -z 1.0 -s y " + ex2;

        try
        {
            // Start the process with the info we specified.
            // Call WaitForExit and then the using statement will close.
            using (Process exeProcess = Process.Start(startInfo))
            {
                exeProcess.WaitForExit();
            }
        }
        catch
        {
             // Log error.
        }
    }
}

For Kotlin:

val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager

fun showKeyboard() {
        imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0)
    }

fun hideKeyboard() {
        imm.hideSoftInputFromWindow(phoneNoInputTxt.windowToken, 0);
    }

Then just call what you want!

!== should match the value and data type

!= just match the value ignoring the data type

$num = '1';
$num2 = 1;

$num == $num2; // returns true    
$num === $num2; // returns false because $num is a string and $num2 is an integer

On some systems (Windows with VC springs to mind, currently), RAND_MAX is ridiculously small, i. e. only 15 bit. When dividing by RAND_MAX you are only generating a mantissa of 15 bit instead of the 23 possible bits. This may or may not be a problem for you, but you're missing out some values in that case.

Oh, just noticed that there was already a comment for that problem. Anyway, here's some code that might solve this for you:

float r = (float)((rand() << 15 + rand()) & ((1 << 24) - 1)) / (1 << 24);

Untested, but might work :-)

You can create an array with a range using splat,

>> a=*(1..10)
=> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

using Kernel Array method,

Array (1..10)
=> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

or using to_a

(1..10).to_a
=> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

Swift 4

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
    let delete = UITableViewRowAction(style: .destructive, title: "delete") { (action, indexPath) in
        // delete item at indexPath
    tableView.deleteRows(at: [indexPath], with: .fade)

    }
    return [delete]
}

foreach(Foos foo in Enum.GetValues(typeof(Foos)))

create or replace procedure delete_duplicate_enq as
    cursor c1 is
    select *
    from enquiry;
begin
    for z in c1 loop
        delete enquiry
        where enquiry.enquiryno = z.enquiryno
        and rowid > any
        (select rowid
        from enquiry
        where enquiry.enquiryno = z.enquiryno);
    end loop;
 end delete_duplicate_enq;

-z

string is null, that is, has zero length

String=''   # Zero-length ("null") string variable.

if [ -z "$String" ]
then
  echo "\$String is null."
else
  echo "\$String is NOT null."
fi     # $String is null.

What exactly are the rules for requesting retransmission of lost data?

The receiver does not request the retransmission. The sender waits for an ACK for the byte-range sent to the client and when not received, resends the packets, after a particular interval. This is ARQ (Automatic Repeat reQuest). There are several ways in which this is implemented.

Stop-and-wait ARQ
Go-Back-N ARQ
Selective Repeat ARQ

are detailed in the RFC 3366.

At what time frequency are the retransmission requests performed?

The retransmissions-times and the number of attempts isn't enforced by the standard. It is implemented differently by different operating systems, but the methodology is fixed. (One of the ways to fingerprint OSs perhaps?)

The timeouts are measured in terms of the RTT (Round Trip Time) times. But this isn't needed very often due to Fast-retransmit which kicks in when 3 Duplicate ACKs are received.

Is there an upper bound on the number?

Yes there is. After a certain number of retries, the host is considered to be "down" and the sender gives up and tears down the TCP connection.

Is there functionality for the client to indicate to the server to forget about the whole TCP segment for which part went missing when the IP packet went missing?

The whole point is reliable communication. If you wanted the client to forget about some part, you wouldn't be using TCP in the first place. (UDP perhaps?)

I'm not 100% sure that I understand your question, so tell me if I'm wrong.

If I got it right, you are reading jbytes that are technically signed chars, but really pixel values ranging from 0 to 255, and you're wondering how you should handle them without corrupting the values in the process.

Then, you should do the following:

• convert jbytes to unsigned char before doing anything else, this will definetly restore the pixel values you are trying to manipulate

• use a larger signed integer type, such as int while doing intermediate calculations, this to make sure that over- and underflows can be detected and dealt with (in particular, not casting to a signed type could force to compiler to promote every type to an unsigned type in which case you wouldn't be able to detect underflows later on)

• when assigning back to a jbyte, you'll want to clamp your value to the 0-255 range, convert to unsigned char and then convert again to signed char: I'm not certain the first conversion is strictly necessary, but you just can't be wrong if you do both

For example:

inline int fromJByte(jbyte pixel) {
    // cast to unsigned char re-interprets values as 0-255
    // cast to int will make intermediate calculations safer
    return static_cast<int>(static_cast<unsigned char>(pixel));
}

inline jbyte fromInt(int pixel) {
    if(pixel < 0)
        pixel = 0;

    if(pixel > 255)
        pixel = 255;

    return static_cast<jbyte>(static_cast<unsigned char>(pixel));
}

jbyte in = ...
int intermediate = fromJByte(in) + 30;
jbyte out = fromInt(intermediate);

As an addition to user39544's answer, one more type of syntax for crontab -e:

@reboot sleep 60 && /usr/local/bin/docker-compose -f /path_to_your_project/docker-compose.yml up -d

You can download in the current directory with a . :

cd # by default, goes to $HOME
scp me@host:/path/to/file .

or in you HOME directly with :

scp me@host:/path/to/file ~

Based on the title of this question, I came here wanting to convert a String into an array of substrings divided by some delimiter. I will add that answer here for others who may have the same question.

This makes an array of words by splitting the string at every space:

String str = "string to string array conversion in java";
String delimiter = " ";
String strArray[] = str.split(delimiter);

This creates the following array:

// [string, to, string, array, conversion, in, java]

Tested in Java 8

According to Angular2 documentation you should use:

@RouteConfig([
   {path: '/login/:token', name: 'Login', component: LoginComponent},
])

@Component({ template: 'login: {{token}}' })
class LoginComponent{
   token: string;
   constructor(params: RouteParams) {
      this.token = params.get('token');
   }
}

I had this issue with gulp. The problem was that gulp added a dependency to my source file and I think npm tried to open it:

{
  "name": "name",
  "version": "2.0.0",
  "description": "",
  "main": "gulpfile.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "appname": "file://gulp",
    "gulp-concat": "^2.6.1",
    "gulp-electron": "^0.1.3",
    "gulp-shell": "^0.5.2",
    "gulp-uglify": "^2.0.0",
    "gulp-util": "^3.0.7",
    "node-7z": "^0.4.0"
  }
}

Make sure that there are no strange references in you package.json file.

Wish I found this thread sooner. The function I made (that took me way too long) is below:

function CheckLetters($field){
    $letters = [
        0 => "a à á â ä æ ã å a",
        1 => "c ç c c",
        2 => "e é è ê ë e e e",
        3 => "i i i í ì ï î",
        4 => "l l",
        5 => "n ñ n",
        6 => "o o ø œ õ ó ò ö ô",
        7 => "s ß s š",
        8 => "u u ú ù ü û",
        9 => "w w",
        10 => "y y ÿ",
        11 => "z z ž z",
    ];
    foreach ($letters as &$values){
        $newValue = substr($values, 0, 1);
        $values = substr($values, 2, strlen($values));
        $values = explode(" ", $values);
        foreach ($values as &$oldValue){
            while (strpos($field,$oldValue) !== false){
                $field = preg_replace("/" . $oldValue . '/', $newValue, $field, 1);
            }
        }
    }
    return $field;
}

Resharper has the File Structure window which is very similar to eclipse outline view. Originally answered in:

Visual Studio 2012: List of all Methods in class

Resharper help: http://www.jetbrains.com/resharper/webhelp/Reference__Windows__File_Structure_Window.html

I figured out a simplest way. You don't need to install package ThenInclude.EF or you don't need to use ThenInclude for all nested navigation properties. Just do like as shown below, EF will take care rest for you. example:

var thenInclude = context.One.Include(x => x.Twoes.Threes.Fours.Fives.Sixes)
.Include(x=> x.Other)
.ToList();

The problem with rstrip is that it does not work in all cases (as I myself have seen few). Instead you can use - text= text.replace("\n"," ") this will remove all new line \n with a space.

Thanks in advance guys for your upvotes.

In JSFiddle, when you set the wrapping to "onLoad" or "onDomready", the functions you define are only defined inside that block, and cannot be accessed by outside event handlers.

Easiest fix is to change:

function something(...)

To:

window.something = function(...)

Things changed a lot since the answer was posted. Now you will see a small key symbol on the right hand side of the URL bar.
Click the symbol and it will take you directly to the saved password dialog where you can remove the password.

Having read various versions of this question and searching around I've come up with quite a clean, js-free, solution. It's similar to @allcaps solution but avoids the issue of the input font being changed away from the main document font.

Use the ::input-placeholder attribute to specifically style the placeholder text. This allows you to use your icon font as the placeholder font and your body (or other font) as the actual input text. Currently you need to specify vendor-specific selectors.

This works well as long as you don't need a combination of icon and text in your input element. If you do then you'll need to put up with the placeholder text being default browser font (plain serif on mine) for words.

E.g.
HTML

<p class="wrapper">
    <input class="icon" type="text" placeholder="&#61442;" />
</p>

CSS

.wrapper {
    font-family:'arial', sans-serif;
}
input.icon::-webkit-input-placeholder {
    font-family:'FontAwesome';
}

Fiddle with browser prefixed selectors: http://jsfiddle.net/gA4rx/78/

Note that you need to define each browser-specific selector as a seperate rule. If you combine them the browser will ignore it.

My answer might be late for this post. It can be achieved through inline css within anchor tag only.

<a [routerLink]="['/user']" [style.pointer-events]="isDisabled ?'none':'auto'">click-label</a>

Considering isDisabled is a property in component which can be true or false.

Plunker for it: https://embed.plnkr.co/TOh8LM/

This worked for me. Its tedious to set all the colour options for a series, especially if it's dynamic

plotOptions: {
  column: {
   colorByPoint: true
  }
}

Use Either Debug.WriteLine() or Trace.WriteLine(). If in release mode, only the latter will appear in the output window, in debug mode, both will.

You can use

window.top

see the following.

<head>
    <script>
    function abc() {
        alert("sss");
    }
    </script>
</head>
<body>
    <iframe id="myFrame">
        <a onclick="window.top.abc();" href="#">Click Me</a>
    </iframe>
</body>

This is a good JavaScript solution to the validation issue you have:

/\b\d{5}-\d{4}\b/

Change the key of the component.

<Component key="1" />

<Component key="2" />

Component will be unmounted and a new instance of Component will be mounted since the key has changed.

edit: Documented on You Probably Don't Need Derived State:

When a key changes, React will create a new component instance rather than update the current one. Keys are usually used for dynamic lists but are also useful here.

Give the container class

.container{
    height: 100vh;
    width: 100vw;
    display: flex;
}

Give the div that's inside the container:

align-content: center;

All the content inside this div will show up in the middle of the page.

If you want to use mod_rewrite for access control you can use condition like user agent, http referrer, remote addr etc.

Example

RewriteCond %{REMOTE_ADDR} !=*.*.*.* #you ip address
RewriteRule ^$ - [F]

Have you seen this post on the subversion site? You could also potentially try validating and "fixing" the database directly as described here. (Note that I'm no expert, I just did a quick google search. May not be related to your issues at all).

Personally, I'd try checking out the repo again and reapplying your changes. Not sure if this is possible though in your case?

Or you simply manage it like full IIS by using Jexus Manager for IIS Express, an open source project I work on

RxJS 6

router.events.pipe(filter(event => event instanceof NavigationStart))

Thanks to Peilonrayz (see comments below)

new router >= RC.3

import { Router, NavigationStart, NavigationEnd, NavigationError, NavigationCancel, RoutesRecognized } from '@angular/router';

constructor(router:Router) {
  router.events.forEach((event) => {
    if(event instanceof NavigationStart) {
    }
    // NavigationEnd
    // NavigationCancel
    // NavigationError
    // RoutesRecognized
  });
}

You can also filter by the given event:

import 'rxjs/add/operator/filter';

constructor(router:Router) {
  router.events
    .filter(event => event instanceof NavigationStart)
    .subscribe((event:NavigationStart) => {
      // You only receive NavigationStart events
    });
}

Using the pairwise operator to get the previous and current event also is an nice idea. https://github.com/angular/angular/issues/11268#issuecomment-244601977

import 'rxjs/add/operator/pairwise';
import { Router } from '@angular/router';

export class AppComponent {
    constructor(private router: Router) {
        this.router.events.pairwise().subscribe((event) => {
            console.log(event);
        });
    };
}

If you only want to know if any item of d is contained in paid[j], as you literally say:

if any(x in paid[j] for x in d): ...

If you also want to know which items of d are contained in paid[j]:

contained = [x for x in d if x in paid[j]]

contained will be an empty list if no items of d are contained in paid[j].

There are other solutions yet if what you want is yet another alternative, e.g., get the first item of d contained in paid[j] (and None if no item is so contained):

firstone = next((x for x in d if x in paid[j]), None)

BTW, since in a comment you mention sentences and words, maybe you don't necessarily want a string check (which is what all of my examples are doing), because they can't consider word boundaries -- e.g., each example will say that 'cat' is in 'obfuscate' (because, 'obfuscate' contains 'cat' as a substring). To allow checks on word boundaries, rather than simple substring checks, you might productively use regular expressions... but I suggest you open a separate question on that, if that's what you require -- all of the code snippets in this answer, depending on your exact requirements, will work equally well if you change the predicate x in paid[j] into some more sophisticated predicate such as somere.search(paid[j]) for an appropriate RE object somere. (Python 2.6 or better -- slight differences in 2.5 and earlier).

If your intention is something else again, such as getting one or all of the indices in d of the items satisfying your constrain, there are easy solutions for those different problems, too... but, if what you actually require is so far away from what you said, I'd better stop guessing and hope you clarify;-).

Another option is to wrap JSON dumping in its own class:

import json

class FileItem:
    def __init__(self, fname):
        self.fname = fname

    def __repr__(self):
        return json.dumps(self.__dict__)

Or, even better, subclassing FileItem class from a JsonSerializable class:

import json

class JsonSerializable(object):
    def toJson(self):
        return json.dumps(self.__dict__)

    def __repr__(self):
        return self.toJson()


class FileItem(JsonSerializable):
    def __init__(self, fname):
        self.fname = fname

Testing:

>>> f = FileItem('/foo/bar')
>>> f.toJson()
'{"fname": "/foo/bar"}'
>>> f
'{"fname": "/foo/bar"}'
>>> str(f) # string coercion
'{"fname": "/foo/bar"}'

This is it guys! FIXED!

Wait and see: https://bugzilla.mozilla.org/show_bug.cgi?id=649849

or workaround

For those wondering:

https://bugzilla.mozilla.org/show_bug.cgi?id=649849#c59

First, because the bug has a lot of hostile spam in it, it creates a hostile workplace for anyone who gets assigned to this.

Secondly, the person who has the ability to do this (which includes rewriting ) has been allocated to another project (b2g) for the time being and wont have time until that project get nearer to completion.

Third, even when that person has the time again, there is no guarantee that this will be a priority because, despite webkit having this, it breaks the spec for how is supposed to work (This is what I was told, I do not personally know the spec)

Now see https://wiki.mozilla.org/B2G/Schedule_Roadmap ;)

The page no longer exists and the bug hasn't be fixed but an acceptable workaround came from João Cunha, you guys can thank him for now!

This is the way it worked for me, because with other methods the form was sent empty:

<form name="yourform" id="yourform" method="POST" action="yourpage.html">
    <input type=hidden name="data" value="yourdata">
    <input type="submit" id="send" name="send" value="Send">
</form>
<script>            
    document.addEventListener("DOMContentLoaded", function(event) {
            document.createElement('form').submit.call(document.getElementById('yourform'));
            });         
</script>

yes... This is for each loop in java.

Generally this loop is become useful when you are retrieving data or object from the database.

Syntex :

for(Object obj : Collection obj)
{
     //Code enter code here
}

Example :

for(User user : userList)
{
     System.out.println("USer NAme :" + user.name);
   // etc etc
}

This is for each loop.

it will incremental by automatically. one by one from collection to USer object data has been filled. and working.

Use the following query:

ALTER TABLE tableName CHANGE oldcolname newcolname datatype(length);

The RENAME function is used in Oracle databases.

ALTER TABLE tableName RENAME COLUMN oldcolname TO newcolname datatype(length);

@lad2025 mentions it below, but I thought it'd be nice to add what he said. Thank you @lad2025!

You can use the RENAME COLUMN in MySQL 8.0 to rename any column you need renamed.

ALTER TABLE table_name RENAME COLUMN old_col_name TO new_col_name;

ALTER TABLE Syntax: RENAME COLUMN:

• Can change a column name but not its definition.
• More convenient than CHANGE to rename a column without changing its definition.

int add(int x, int y); // forward declaration using function prototype

Can you explain "forward declaration" more further? What is the problem if we use it in the main() function?

It's same as #include"add.h". If you know,preprocessor expands the file which you mention in #include, in the .cpp file where you write the #include directive. That means, if you write #include"add.h", you get the same thing, it is as if you doing "forward declaration".

I'm assuming that add.h has this line:

int add(int x, int y); 

Just use it...

Firstly include the unistd.h header file, #include<unistd.h>, and use this function for pausing your program execution for desired number of seconds:

sleep(x);

x can take any value in seconds.

If you want to pause the program for 5 seconds it is like this:

sleep(5);

It is correct and I use it frequently.

It is valid for C and C++.

I'v tried pyenv and it's very handy for switching python versions (global, local in folder or in the virtualenv):

brew install pyenv

then install Python version you want:

pyenv install 3.5.0

and simply create virtualenv with path to needed interpreter version:

virtualenv -p /Users/johnny/.pyenv/versions/3.5.0/bin/python3.5 myenv

That's it, check the version:

. ./myenv/bin/activate && python -V

There are also plugin for pyenv pyenv-virtualenv but it didn't work for me somehow.

let str = 'https://example.com is a great site'
str.replace(/(https?:\/\/[^\s]+)/g,"<a href='$1' target='_blank' >$1</a>")

Short Code Big Work!...

Result:-

 <a href="https://example.com" target="_blank" > https://example.com </a>

For the benefit of anyone reading this later, you need to link against it as Fred said:

gcc fib.c -lm -o fibo

One good way to find out what library you need to link is by checking the man page if one exists. For example, man pow and man floor will both tell you:

Link with -lm.

THE PROBLEM is here: onClick={this.handleButtonChange(false)}

When you pass this.handleButtonChange(false) to onClick, you are actually calling the function with value = false and setting onClick to the function's return value, which is undefined. Also, calling this.handleButtonChange(false) then calls this.setState() which triggers a re-render, resulting in an infinite render loop.

THE SOLUTION is to pass the function in a lambda: onClick={() => this.handleButtonChange(false)}. Here you are setting onClick to equal a function that will call handleButtonChange(false) when the button is clicked.

The below example may help:

function handleButtonChange(value){
  console.log("State updated!")
}

console.log(handleButtonChange(false))
//output: State updated!
//output: undefined

console.log(() => handleButtonChange(false))
//output: ()=>{handleButtonChange(false);}

My way

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.beans.BeanInfo;
import java.beans.Introspector;
import java.beans.PropertyDescriptor;

public class ReadAnnotation {
    private static final Logger LOGGER = LoggerFactory.getLogger(ReadAnnotation.class);

    public static boolean hasIgnoreAnnotation(String fieldName, Class entity) throws NoSuchFieldException {
        return entity.getDeclaredField(fieldName).isAnnotationPresent(IgnoreAnnotation.class);
    }

    public static boolean isSkip(PropertyDescriptor propertyDescriptor, Class entity) {
        boolean isIgnoreField;
        try {
            isIgnoreField = hasIgnoreAnnotation(propertyDescriptor.getName(), entity);
        } catch (NoSuchFieldException e) {
            LOGGER.error("Can not check IgnoreAnnotation", e);
            isIgnoreField = true;
        }
        return isIgnoreField;
    }

    public void testIsSkip() throws Exception {
        Class<TestClass> entity = TestClass.class;
        BeanInfo beanInfo = Introspector.getBeanInfo(entity);

        for (PropertyDescriptor propertyDescriptor : beanInfo.getPropertyDescriptors()) {
            System.out.printf("Field %s, has annotation %b", propertyDescriptor.getName(),  isSkip(propertyDescriptor, entity));
        }
    }

}

Simply using an outer directory for the output, solved the problem for me.

sudo tar czf ./../31OCT18.tar.gz ./

Well any Javascript object functions sort-of like a "map"

randomObject['hello'] = 'world';

Typically people build simple objects for the purpose:

var myMap = {};

// ...

myMap[newKey] = newValue;

edit — well the problem with having an explicit "put" function is that you'd then have to go to pains to avoid having the function itself look like part of the map. It's not really a Javascripty thing to do.

13 Feb 2014 — modern JavaScript has facilities for creating object properties that aren't enumerable, and it's pretty easy to do. However, it's still the case that a "put" property, enumerable or not, would claim the property name "put" and make it unavailable. That is, there's still only one namespace per object.

I finally figured out a how to use Maven. From within Eclipse, create a new Maven project.

Download Maven, extract the archive, add the /bin folder to path.

Validate install from command-line by running mvn -v (will print version and java install path)

Change to the project root folder (where pom.xml is located) and run:

mvn dependency:copy-dependencies

All jar-files are downloaded to /target/dependency.

To set another output directory:

mvn dependency:copy-dependencies -DoutputDirectory="c:\temp"

Now it's possible to re-use this Maven-project for all dependency downloads by altering the pom.xml

Add jars to java project by build path -> configure build path -> libraries -> add JARs..

Function names should be lowercase, with words separated by underscores as necessary to improve readability. mixedCase is allowed only in contexts where that's already the prevailing style

This works fine for me:

`%nin%` <- Negate(`%in%`)

This was also an easy way to add script and css in main.php

<script src="<?=Yii::app()->theme->baseUrl; ?>/js/bootstrap.min.js"></script>
<link href="<?=Yii::app()->theme->baseUrl; ?>/css/bootstrap.css" rel="stylesheet" type="text/css">

time.time() return the unix timestamp. you could use datetime library to get local time or UTC time.

import datetime

local_time = datetime.datetime.now()
print(local_time.strftime('%Y%m%d %H%M%S'))

utc_time = datetime.datetime.utcnow() 
print(utc_time.strftime('%Y%m%d %H%M%S'))

@JorgeGRC Thanks for your answer. One thing though, the "maybe" part is very important. If you do have parameter(s), you must include it/them on your template as well and be sure to specify your locals e.g. updateFn({msg: "Directive Args"}.

If you have a parameter where you may need to indicate the absence of a value, it's common practice to make the parameter a pointer value and pass in NULL.

A better solution in most cases (from a safety perspective) is to use boost::optional. This allows you to pass in optional values by reference and also as a return value.

// Sample method using optional as input parameter
void PrintOptional(const boost::optional<std::string>& optional_str)
{
    if (optional_str)
    {
       cout << *optional_str << std::endl;
    }
    else
    {
       cout << "(no string)" << std::endl;
    }
}

// Sample method using optional as return value
boost::optional<int> ReturnOptional(bool return_nothing)
{
    if (return_nothing)
    {
       return boost::optional<int>();
    }

    return boost::optional<int>(42);
}

I guess you want user to be redirected to ~/AreaZ URL once (s)he has visited ~/ URL. I'd achieve by means of the following code within your root HomeController.

public class HomeController
{
    public ActionResult Index()
    {
        return RedirectToAction("ActionY", "ControllerX", new { Area = "AreaZ" });
    }
}

And the following route in Global.asax.

routes.MapRoute(
    "Redirection to AreaZ",
    String.Empty,
    new { controller = "Home ", action = "Index" }
);

If you know you will want a 'c' key, but do not know the value, insert 'c' with a dummy value when you create the dict.

d1 = OrderedDict([('c', None), ('a', '1'), ('b', '2')])

and change the value later.

d1['c'] = 3
