There is actually a pretty critical difference, insofar as jQuery's Deferreds are meant to be an implementations of Promises (and jQuery3.0 actually tries to bring them into spec).

The key difference between done/then is that

• .done() ALWAYS returns the same Promise/wrapped values it started with, regardless of what you do or what you return.
• .then() always returns a NEW Promise, and you are in charge of controlling what that Promise is based on what the function you passed it returned.

Translated from jQuery into native ES2015 Promises, .done() is sort of like implementing a "tap" structure around a function in a Promise chain, in that it will, if the chain is in the "resolve" state, pass a value to a function... but the result of that function will NOT affect the chain itself.

const doneWrap = fn => x => { fn(x); return x };

Promise.resolve(5)
       .then(doneWrap( x => x + 1))
       .then(doneWrap(console.log.bind(console)));

$.Deferred().resolve(5)
            .done(x => x + 1)
            .done(console.log.bind(console));

Those will both log 5, not 6.

Note that I used done and doneWrap to do logging, not .then. That's because console.log functions don't actually return anything. And what happens if you pass .then a function that doesn't return anything?

Promise.resolve(5)
       .then(doneWrap( x => x + 1))
       .then(console.log.bind(console))
       .then(console.log.bind(console));

That will log:

5

undefined

What happened? When I used .then and passed it a function that didn't return anything, it's implicit result was "undefined"... which of course returned a Promise[undefined] to the next then method, which logged undefined. So the original value we started with was basically lost.

.then() is, at heart, a form of function composition: the result of each step is used as the argument for the function in the next step. That's why .done is best thought of as a "tap"-> it's not actually part of the composition, just something that sneaks a look at the value at a certain step and runs a function at that value, but doesn't actually alter the composition in any way.

This is a pretty fundamental difference, and there's a probably a good reason why native Promises don't have a .done method implemented themselves. We don't eve have to get into why there's no .fail method, because that's even more complicated (namely, .fail/.catch are NOT mirrors of .done/.then -> functions in .catch that return bare values do not "stay" rejected like those passed to .then, they resolve!)

The same, Server.UrlEncode() calls HttpUtility.UrlEncode()

To process a file line-by-line, you simply need to decouple the reading of the file and the code that acts upon that input. You can accomplish this by buffering your input until you hit a newline. Assuming we have one JSON object per line (basically, format B):

var stream = fs.createReadStream(filePath, {flags: 'r', encoding: 'utf-8'});
var buf = '';

stream.on('data', function(d) {
    buf += d.toString(); // when data is read, stash it in a string buffer
    pump(); // then process the buffer
});

function pump() {
    var pos;

    while ((pos = buf.indexOf('\n')) >= 0) { // keep going while there's a newline somewhere in the buffer
        if (pos == 0) { // if there's more than one newline in a row, the buffer will now start with a newline
            buf = buf.slice(1); // discard it
            continue; // so that the next iteration will start with data
        }
        processLine(buf.slice(0,pos)); // hand off the line
        buf = buf.slice(pos+1); // and slice the processed data off the buffer
    }
}

function processLine(line) { // here's where we do something with a line

    if (line[line.length-1] == '\r') line=line.substr(0,line.length-1); // discard CR (0x0D)

    if (line.length > 0) { // ignore empty lines
        var obj = JSON.parse(line); // parse the JSON
        console.log(obj); // do something with the data here!
    }
}

Each time the file stream receives data from the file system, it's stashed in a buffer, and then pump is called.

If there's no newline in the buffer, pump simply returns without doing anything. More data (and potentially a newline) will be added to the buffer the next time the stream gets data, and then we'll have a complete object.

If there is a newline, pump slices off the buffer from the beginning to the newline and hands it off to process. It then checks again if there's another newline in the buffer (the while loop). In this way, we can process all of the lines that were read in the current chunk.

Finally, process is called once per input line. If present, it strips off the carriage return character (to avoid issues with line endings – LF vs CRLF), and then calls JSON.parse one the line. At this point, you can do whatever you need to with your object.

Note that JSON.parse is strict about what it accepts as input; you must quote your identifiers and string values with double quotes. In other words, {name:'thing1'} will throw an error; you must use {"name":"thing1"}.

Because no more than a chunk of data will ever be in memory at a time, this will be extremely memory efficient. It will also be extremely fast. A quick test showed I processed 10,000 rows in under 15ms.

The answer of Uttam didnt work for me. I just got null when I do:

Bitmap bitmap = BitmapFactory.decodeByteArray(bitmapdata, 0, bitmapdata.length);

In my case, bitmapdata only has the buffer of the pixels, so it is imposible for the function decodeByteArray to guess which the width, the height and the color bits use. So I tried this and it worked:

//Create bitmap with width, height, and 4 bytes color (RGBA)    
Bitmap bmp = Bitmap.createBitmap(imageWidth, imageHeight, Bitmap.Config.ARGB_8888);
ByteBuffer buffer = ByteBuffer.wrap(bitmapdata);
bmp.copyPixelsFromBuffer(buffer);

Check https://developer.android.com/reference/android/graphics/Bitmap.Config.html for different color options

I guess this feature was added since the OP but for future reference errors that would output in the command window can be redirected to a file independent of the standard output

command 1> file - Write the standard output of command to file

command 2> file - Write the standard error of command to file

Here's one generalized from something I just used. I'm posting it since it's a very simple example, and it demonstrates a practical use case along with default arguments:

#include <vector>

template <class T> class Alloc final { /*...*/ };

template <template <class T> class allocator=Alloc> class MyClass final {
  public:
    std::vector<short,allocator<short>> field0;
    std::vector<float,allocator<float>> field1;
};

You can compute pairwise cosine similarity on the rows of a sparse matrix directly using sklearn. As of version 0.17 it also supports sparse output:

from sklearn.metrics.pairwise import cosine_similarity
from scipy import sparse

A =  np.array([[0, 1, 0, 0, 1], [0, 0, 1, 1, 1],[1, 1, 0, 1, 0]])
A_sparse = sparse.csr_matrix(A)

similarities = cosine_similarity(A_sparse)
print('pairwise dense output:\n {}\n'.format(similarities))

#also can output sparse matrices
similarities_sparse = cosine_similarity(A_sparse,dense_output=False)
print('pairwise sparse output:\n {}\n'.format(similarities_sparse))

Results:

pairwise dense output:
[[ 1.          0.40824829  0.40824829]
[ 0.40824829  1.          0.33333333]
[ 0.40824829  0.33333333  1.        ]]

pairwise sparse output:
(0, 1)  0.408248290464
(0, 2)  0.408248290464
(0, 0)  1.0
(1, 0)  0.408248290464
(1, 2)  0.333333333333
(1, 1)  1.0
(2, 1)  0.333333333333
(2, 0)  0.408248290464
(2, 2)  1.0

If you want column-wise cosine similarities simply transpose your input matrix beforehand:

A_sparse.transpose()

Update 2019

The :has() pseudo-selector is propsed in the CSS Selectors 4 spec, and will address this use case once implemented.

To use it, we will write something like:

.foo > .bar:has(> .baz) { /* style here */ }

In a structure like:

<div class="foo">
  <div class="bar">
    <div class="baz">Baz!</div>
  </div>
</div>

This CSS will target the .bar div - because it both has a parent .foo and from its position in the DOM, > .baz resolves to a valid element target.

Original Answer (left for historical purposes) - this portion is no longer accurate

For completeness, I wanted to point out that in the Selectors 4 specification (currently in proposal), this will become possible. Specifically, we will gain Subject Selectors, which will be used in the following format:

!div > span { /* style here */

The ! before the div selector indicates that it is the element to be styled, rather than the span. Unfortunately, no modern browsers (as of the time of this posting) have implemented this as part of their CSS support. There is, however, support via a JavaScript library called Sel, if you want to go down the path of exploration further.

A somewhat different approach using ggplot2:

dat <- read.table(text = "A   B   C   D   E   F    G
1 480 780 431 295 670 360  190
2 720 350 377 255 340 615  345
3 460 480 179 560  60 735 1260
4 220 240 876 789 820 100   75", header = TRUE)

library(reshape2)

dat$row <- seq_len(nrow(dat))
dat2 <- melt(dat, id.vars = "row")

library(ggplot2)

ggplot(dat2, aes(x = variable, y = value, fill = row)) + 
  geom_bar(stat = "identity") +
  xlab("\nType") +
  ylab("Time\n") +
  guides(fill = FALSE) +
  theme_bw()

this gives:

When you want to include a legend, delete the guides(fill = FALSE) line.

The simplest method is

$dateArray = explode('/', $_POST['date']);
$date = $dateArray[2].'-'.$dateArray[0].'-'.$dateArray[1];

$sql = mysql_query("INSERT INTO user_date (column,column,column) VALUES('',$name,$date)") or die (mysql_error());

1. you have to have a reference to the form object in order to access its elements
2. the elements have to be declared public in order for another class to access them
3. don't do this - your class has to know too much about how your form is implemented; do not expose form controls outside of the form class
4. instead, make public properties on your form to get/set the values you are interested in
5. post more details of what you want and why, it sounds like you may be heading off in a direction that is not consistent with good encapsulation practices

You may put some text in the search and filter out the Logcat result.
That was the reason for my problem :)

Yet another more contemporary option (no pun intended) is to disable all the options of the select element other then the selected one.

note however that this is an HTML 4.0 feature and ie 6,7,8 beta 1 seem to not respect this.

http://www.gtalbot.org/BrowserBugsSection/MSIE7Bugs/OptionDisabledSupport.html

Simply do it.

this.state={f_name:""};

textChangeHandler = async (key, val) => {
    await this.setState({ [key]: val });
}

<Textfield onChangeText={val => this.textChangeHandler('f_name', val)}>

You should bind the tap event, the click does not exist on mobile safari or in the UIWbview. You can also use this polyfill ,to avoid the 300ms delay when a link is touched.

Void is an incomplete type which, by definition, can't be an lvalue. That means it can't get assigned a value.

So it also can't hold any value.

Here's a subquery for you!

List<int> IdsToFind = new List<int>() {2, 3, 4};

db.Users
.Where(u => SqlMethods.Like(u.LastName, "%fra%"))
.Where(u =>
    db.CompanyRolesToUsers
    .Where(crtu => IdsToFind.Contains(crtu.CompanyRoleId))
    .Select(crtu =>  crtu.UserId)
    .Contains(u.Id)
)

Regarding this portion of the question:

predicateAnd = predicateAnd.And(c => c.LastName.Contains(
                                TextBoxLastName.Text.Trim()));

I strongly recommend extracting the string from the textbox before authoring the query.

string searchString = TextBoxLastName.Text.Trim();
predicateAnd = predicateAnd.And(c => c.LastName.Contains( searchString));

You want to maintain good control over what gets sent to the database. In the original code, one possible reading is that an untrimmed string gets sent into the database for trimming - which is not good work for the database to be doing.

Luckily, C# has no C/C++-style preprocessor - only conditional compilation and pragmas (and possibly something else I cannot recall) are supported. Unfortunatelly, C# has no metaprogramming capabilities (this may actually relate to your question to some extent).

It seems like it exists a bug in jQuery reported here : http://bugs.jquery.com/ticket/13183 that breaks the Fancybox script.

Also check https://github.com/fancyapps/fancyBox/issues/485 for further reference.

As a workaround, rollback to jQuery v1.8.3 while either the jQuery bug is fixed or Fancybox is patched.

UPDATE (Jan 16, 2013): Fancybox v2.1.4 has been released and now it works fine with jQuery v1.9.0.

For fancybox v1.3.4- you still need to rollback to jQuery v1.8.3 or apply the migration script as pointed out by @Manu's answer.

UPDATE (Jan 17, 2013): Workaround for users of Fancybox v1.3.4 :

Patch the fancybox js file to make it work with jQuery v1.9.0 as follow :

1. Open the jquery.fancybox-1.3.4.js file (full version, not pack version) with a text/html editor.

2. Find around the line 29 where it says :

   isIE6 = $.browser.msie && $.browser.version < 7 && !window.XMLHttpRequest,
   

   and replace it by (EDITED March 19, 2013: more accurate filter):

   isIE6 = navigator.userAgent.match(/msie [6]/i) && !window.XMLHttpRequest,
   

   UPDATE (March 19, 2013): Also replace $.browser.msie by navigator.userAgent.match(/msie [6]/i) around line 615 (and/or replace all $.browser.msie instances, if any), thanks joofow ... that's it!

Or download the already patched version from HERE (UPDATED March 19, 2013 ... thanks fairylee for pointing out the extra closing bracket)

NOTE: this is an unofficial patch and is unsupported by Fancybox's author, however it works as is. You may use it at your own risk ;)

Optionally, you may rather rollback to jQuery v1.8.3 or apply the migration script as pointed out by @Manu's answer.

You need ReDim:

m = 5
n = 8
Dim my_array()
ReDim my_array(1 To m, 1 To n)
For i = 1 To m
  For j = 1 To n
    my_array(i, j) = i * j
  Next
Next

For i = 1 To m
  For j = 1 To n
    Cells(i, j) = my_array(i, j)
  Next
Next

As others have pointed out, your actual problem would be better solved with ranges. You could try something like this:

Dim r1 As Range
Dim r2 As Range
Dim ws1 As Worksheet
Dim ws2 As Worksheet

Set ws1 = Worksheets("Sheet1")
Set ws2 = Worksheets("Sheet2")
totalRow = ws1.Range("A1").End(xlDown).Row
totalCol = ws1.Range("A1").End(xlToRight).Column

Set r1 = ws1.Range(ws1.Cells(1, 1), ws1.Cells(totalRow, totalCol))
Set r2 = ws2.Range(ws2.Cells(1, 1), ws2.Cells(totalRow, totalCol))
r2.Value = r1.Value

Do not use authorization instead of authentication. I should get whole access to service all clients with header. The working code is :

public class TokenAuthenticationHandler : AuthenticationHandler<TokenAuthenticationOptions> 
{
    public IServiceProvider ServiceProvider { get; set; }

    public TokenAuthenticationHandler (IOptionsMonitor<TokenAuthenticationOptions> options, ILoggerFactory logger, UrlEncoder encoder, ISystemClock clock, IServiceProvider serviceProvider) 
        : base (options, logger, encoder, clock) 
    {
        ServiceProvider = serviceProvider;
    }

    protected override Task<AuthenticateResult> HandleAuthenticateAsync () 
    {
        var headers = Request.Headers;
        var token = "X-Auth-Token".GetHeaderOrCookieValue (Request);

        if (string.IsNullOrEmpty (token)) {
            return Task.FromResult (AuthenticateResult.Fail ("Token is null"));
        }           

        bool isValidToken = false; // check token here

        if (!isValidToken) {
            return Task.FromResult (AuthenticateResult.Fail ($"Balancer not authorize token : for token={token}"));
        }

        var claims = new [] { new Claim ("token", token) };
        var identity = new ClaimsIdentity (claims, nameof (TokenAuthenticationHandler));
        var ticket = new AuthenticationTicket (new ClaimsPrincipal (identity), this.Scheme.Name);
        return Task.FromResult (AuthenticateResult.Success (ticket));
    }
}

Startup.cs :

#region Authentication
services.AddAuthentication (o => {
    o.DefaultScheme = SchemesNamesConst.TokenAuthenticationDefaultScheme;
})
.AddScheme<TokenAuthenticationOptions, TokenAuthenticationHandler> (SchemesNamesConst.TokenAuthenticationDefaultScheme, o => { });
#endregion

And mycontroller.cs

[Authorize(AuthenticationSchemes = SchemesNamesConst.TokenAuthenticationDefaultScheme)]
public class MainController : BaseController
{ ... }

I can't find TokenAuthenticationOptions now, but it was empty. I found the same class PhoneNumberAuthenticationOptions :

public class PhoneNumberAuthenticationOptions : AuthenticationSchemeOptions
{
    public Regex PhoneMask { get; set; }// = new Regex("7\\d{10}");
}

You should define static class SchemesNamesConst. Something like:

public static class SchemesNamesConst
{
    public const string TokenAuthenticationDefaultScheme = "TokenAuthenticationScheme";
}

Indentation in Python is important and this is just not for code readability, unlike many other programming languages. If there is any white space or tab in your code between consecutive commands, python will give this error as Python is sensitive to this. We are likely to get this error when we do copy and paste of code to any Python. Make sure to identify and remove these spaces using a text editor like Notepad++ or manually remove the whitespace from the line of code where you are getting an error.

Step1 :Gives error 
L = [[1, 2, 3], [4, 5, 6], [7, 8, 9, 10]]
print(L[2: ])

Step2: L = [[1, 2, 3], [4, 5, 6], [7, 8, 9, 10]]print(L[2: ])

Step3: No error after space was removed
L = [[1, 2, 3], [4, 5, 6], [7, 8, 9, 10]]
print(L[2: ])
OUTPUT: [[7, 8, 9, 10]]

Thanks!

It is not possible directly. You may as well write some preprocessor which can handle that.

If I understand it correctly then below are the things that can be helpful to achieve that:

• Use a pre-processor which will run through your JS files for example looking for patterns like "@import somefile.js" and replace them with the content of the actual file. Nicholas Zakas(Yahoo) wrote one such library in Java which you can use (http://www.nczonline.net/blog/2009/09/22/introducing-combiner-a-javascriptcss-concatenation-tool/)

• If you are using Ruby on Rails then you can give Jammit asset packaging a try, it uses assets.yml configuration file where you can define your packages which can contain multiple files and then refer them in your actual webpage by the package name.

• Try using a module loader like RequireJS or a script loader like LabJs with the ability to control the loading sequence as well as taking advantage of parallel downloading.

JavaScript currently does not provide a "native" way of including a JavaScript file into another like CSS ( @import ), but all the above mentioned tools/ways can be helpful to achieve the DRY principle you mentioned. I can understand that it may not feel intuitive if you are from a Server-side background but this is the way things are. For front-end developers this problem is typically a "deployment and packaging issue".

Hope it helps.

Just put this line before set OnItemSelectedListener

spinner.setSelection(0,false)

(new Double(d)).longValue() internally just does a cast, so there's no reason to create a Double object.

The first time you run the page, the query_age index doesn't exist because it hasn't been sent over from the form.

When you submit the form it will then exist, and it won't complain about it.

#so change
$_GET['query_age'];
#to:
(!empty($_GET['query_age']) ? $_GET['query_age'] : null);

An <input type=hidden> element is not a hidden input box. It is simply a form field that has a value set via markup or via scripting, not via user input. You can use it for multi-line data too, e.g.

<input type=hidden name=stuff value=
"Hello
world, how
are you?">

If the value contains the Ascii quotation mark ("), then, as for any HTML attribute, you need to use Ascii apostrophes (') as attribute value delimites or escape the quote as ", e.g.

<input type=hidden name=stuff value="A &quot;funny&quot; example">

Some of the answers I've seen explain how to make the contents of a cell invisible, but not how to hide the entire column, which is what I wanted to do.

If you have AutoGenerateColumns = "false" and are actually using BoundField for the column you want to hide, Bala's answer is slick. But if you are using TemplateField for the column, you can handle the DataBound event and do something like this:

protected void gridView_DataBound(object sender, EventArgs e)
{
    const int countriesColumnIndex = 4;

    if (someCondition == true)
    {
        // Hide the Countries column
        this.gridView.Columns[countriesColumnIndex].Visible = false;
    }
}

This may not be what the OP was looking for, but it's the solution I was looking for when I found myself asking the same question.

For a ASP.NET MVC implementation, look at SignalR which is available on NuGet.. note that the NuGet is often out of date from the Git source which gets very frequent commits.

Read more about SignalR on a blog on by Scott Hanselman

Inheritance or generalization is an example of high coupling (i.e. high interdependence). What I meant by this is that in inheritance often the parent class defines base functionalities that is used by its child class and change in methods of parent class directly impact its child classes. Hence we can say that there is a greater degree of interdependence between classes.

Realization or using interface is an example of high cohesion (i.e. low interdependence). What this means is that an interface put forward a contract for any class that implements it but each class has the right to implement methods declared in interface in its own way and changes in method declared in one class doesn't affect any other class.

Does your DLL project have any actual exports? If there are no exports, the linker will not generate an import library .lib file.

In the non-Express version of VS, the import libray name is specfied in the project settings here:

Configuration Properties/Linker/Advanced/Import Library

I assume it's the same in Express (if it even provides the ability to configure the name).

Your two examples are the only things I have ever used the Rows and Columns properties for, but in theory you could do anything with them that can be done with a Range object.

The return type of those properties is itself a Range, so you can do things like:

Dim myRange as Range
Set myRange = Sheet1.Range(Cells(2,2),Cells(8,8))
myRange.Rows(3).Select

Which will select the third row in myRange (Cells B4:H4 in Sheet1).

update: To do what you want to do, you could use:

Dim interestingRows as Range
Set interestingRows = Sheet1.Range(startRow & ":" & endRow)

update #2: Or, to get a subset of rows from within a another range:

Dim someRange As Range
Dim interestingRows As Range

Set myRange = Sheet1.Range(Cells(2, 2), Cells(8, 8))

startRow = 3
endRow = 6

Set interestingRows = Range(myRange.Rows(startRow), myRange.Rows(endRow))

If you are using a templateSelection and ajax, some of these other answers may not work. It seems that creating a new option element and setting the value and text will not satisfy the template method when your data objects use other values than id and text.

Here is what worked for me:

$("#selectElem").select2({
  ajax: { ... },
  data: [YOUR_DEFAULT_OBJECT],
  templateSelection: yourCustomTemplate
} 

Check out the jsFiddle here: https://jsfiddle.net/shanabus/f8h1xnv4

In my case, I had to processResults in since my data did not contain the required id and text fields. If you need to do this, you will also need to run your initial selection through the same function. Like so:

$(".js-select2").select2({
  ajax: {
    url: SOME_URL,
    processResults: processData
  },
  data: processData([YOUR_INIT_OBJECT]).results,
  minimumInputLength: 1,
  templateSelection: myCustomTemplate
});

function processData(data) {
  var mapdata = $.map(data, function (obj) {      
    obj.id = obj.Id;
    obj.text = '[' + obj.Code + '] ' + obj.Description;
    return obj;
  });
  return { results: mapdata }; 
}

function myCustomTemplate(item) {
     return '<strong>' + item.Code + '</strong> - ' + item.Description;
}

You can write a pretty simple embedded Jetty Java server.

Embedded Jetty means that the server (Jetty) shipped together with the application as opposed of deploying the application on external Jetty server.

So if in non-embedded approach your webapp built into WAR file which deployed to some external server (Tomcat / Jetty / etc), in embedded Jetty, you write the webapp and instantiate the jetty server in the same code base.

An example for embedded Jetty Java server you can git clone and use: https://github.com/stas-slu/embedded-jetty-java-server-example

Use immediate children selector >:

$('#tblOne > tbody  > tr')

Description: Selects all direct child elements specified by "child" of elements specified by "parent".

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

Atlast following solved my problem :

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

I had the same problem with Xcode. I followed steps you gave and it didn't work. I became crazy because in every forum I saw, all clues for this problem are the one you gave. I finally saw I put a space after the malloc_error_break, I suppressed it and now it works. A dumb problem but if the solution doesn't work, be sure you haven't put any space before and after the malloc_error_break.

Hope this message will help..

One way I found after some struggling is creating a function which gets data_plot matrix, file name and order as parameter to create boxplots from the given data in the ordered figure (different orders = different figures) and save it under the given file_name.

def plotFigure(data_plot,file_name,order):
    fig = plt.figure(order, figsize=(9, 6))
    ax = fig.add_subplot(111)
    bp = ax.boxplot(data_plot)
    fig.savefig(file_name, bbox_inches='tight')
    plt.close()

What worked for me in Windows 7 is to remove the Host-only Network (in Oracle virtual box Preferences menu [CTRL+G] -> Network -> Host-only Networks). Genymotion will recreate it automatically at the next virtual device start. For the record; I'm using a Nexus S 2.3.7 virtual device.

I have a simple and generic hack to perform key/value if statement instead of boolean-only in mustache (and in an extremely readable fashion!) :

function buildOptions (object) {
    var validTypes = ['string', 'number', 'boolean'];
    var value;
    var key;
    for (key in object) {
        value = object[key];
        if (object.hasOwnProperty(key) && validTypes.indexOf(typeof value) !== -1) {
            object[key + '=' + value] = true;
        }
    }
    return object;
}

With this hack, an object like this:

var contact = {
  "id": 1364,
  "author_name": "Mr Nobody",
  "notified_type": "friendship",
  "action": "create"
};

Will look like this before transformation:

var contact = {
  "id": 1364,
  "id=1364": true,
  "author_name": "Mr Nobody",
  "author_name=Mr Nobody": true,
  "notified_type": "friendship",
  "notified_type=friendship": true,
  "action": "create",
  "action=create": true
};

And your mustache template will look like this:

{{#notified_type=friendship}}
    friendship…
{{/notified_type=friendship}}

{{#notified_type=invite}}
    invite…
{{/notified_type=invite}}

Starting from July 18, 2017 Facebook has decided to disregard custom parameters set by users. This choice blocks many of the possibilities offered by this answer and it also breaks buttons used on several websites.

The quote and hashtag parameters work as of Dec 2018.

Does anyone know if there have been recent changes which could have suddenly stopped this from working?

The parameters have changed. The currently accepted answer states:

Facebook no longer supports custom parameters in sharer.php

But this is not entirely correct. Well, maybe they do not support or endorse them, but custom parameters can be used if you know the correct names. These include:

• URL (of course) ? u
• custom image ? picture
• custom title ? title
• custom quote ? quote
• custom description ? description
• caption (aka website name) ? caption

For instance, you can share this very question with the following URL:

https://www.facebook.com/sharer/sharer.php?u=http%3A%2F%2Fstackoverflow.com%2Fq%2F20956229%2F1101509&picture=http%3A%2F%2Fwww.applezein.net%2Fwordpress%2Fwp-content%2Fuploads%2F2015%2F03%2Ffacebook-logo.jpg&title=A+nice+question+about+Facebook&quote=Does+anyone+know+if+there+have+been+recent+changes+which+could+have+suddenly+stopped+this+from+working%3F&description=Apparently%2C+the+accepted+answer+is+not+correct.

Try it!

I've built a tool which makes it easier to share URLs on Facebook with custom parameters. You can use it to generate your sharer.php link, just press the button and copy the URL from the tab that opens.

This is a crazy thing of apple. When you say self.navigationItem.rightBarButtonItem.title then it will say nil while on the GUI it shows Edit or Save. Fresher likes me will take a lot of time to debug this behavior.

There is a requirement that the Item will show Edit in the firt load then user taps on it It will change to Save title. To archive this, i did as below.

//view did load will say Edit title

private func loadRightBarItem() {
    let logoutBarButtonItem = UIBarButtonItem(title: "Edit", style: .done, target: self, action: #selector(handleEditBtn))
    self.navigationItem.rightBarButtonItem  = logoutBarButtonItem
}

// tap Edit item will change to Save title

@objc private func handleEditBtn() {
    print("clicked on Edit btn")
    let logoutBarButtonItem = UIBarButtonItem(title: "Save", style: .done, target: self, action: #selector(handleSaveBtn))
    self.navigationItem.rightBarButtonItem  = logoutBarButtonItem
    blockEditTable(isBlock: false)
}

//tap Save item will display Edit title

@objc private func handleSaveBtn(){
    print("clicked on Save btn")
    let logoutBarButtonItem = UIBarButtonItem(title: "Edit", style: .done, target: self, action: #selector(handleEditBtn))
    self.navigationItem.rightBarButtonItem  = logoutBarButtonItem

    saveInvitation()
    blockEditTable(isBlock: true)

}

is_numeric returns true for decimals and integers. So if your user lazily enters 1 instead of 1.00 it will still return true:

echo is_numeric(1); // true
echo is_numeric(1.00); // true

You may wish to convert the integer to a decimal with PHP, or let your database do it for you.

What about com.sun.tools.javac.util.Pair?

Not really solve your question but it's an important alternative.

If you want to add custom html to the beginning of the page (inside <body> element), you may use Page.ClientScript.RegisterClientScriptBlock().

Although the method is called "script", but you can add arbitary string, including html.

Task are being executed on the ThreadPool (at least, if you are using the default factory), so aborting the thread cannot affect the tasks. For aborting tasks, see Task Cancellation on msdn.

This should work, but there is a little trick. After you enter the formula, you need to hold down Ctrl+Shift while you press Enter. When you do, you'll see that the formula bar has curly-braces around your formula. This is called an array formula.

For example, if the Months are in cells A2:A100 and the amounts are in cells B2:B100, your formula would look like {=SUM(If(A2:A100="January",B2:B100))}. You don't actually type the curly-braces though.

You could also do something like =SUM((A2:A100="January")*B2:B100). You'd still need to use the trick to get it to work correctly.

I was able to invoke a shell script using this command:

ssh ${serverhost} "./sh/checkScript.ksh"

Of course, checkScript.ksh must exist in the $HOME/sh directory.

I hope this is helpful to you.

Please try this code,

 @Html.DropDownListFor(model => model.Items, new List<SelectListItem>
   { new SelectListItem{Text="Deactive", Value="False"},
     new SelectListItem{Text="Active", Value="True",  Selected = true},
     })

by using jquery to register .mousemove to document to change the image .css left and top to event.pageX and event.pageY.

example as below http://jsfiddle.net/BfLAh/1/

$(document).mousemove(function(e) {
  $("#follow").css({
    left: e.pageX,
    top: e.pageY
  });
});

#follow {
  position: absolute;
  text-align: center;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="follow"><img src="https://placekitten.com/96/140" /><br>Kitteh</br>
</div>

updated to follow slowly

http://jsfiddle.net/BfLAh/3/

for the orientation , you need to get the current css left and css top and compare with event.pageX and event.pageY , then set the image orientation with

-webkit-transform: rotate(-90deg); 
-moz-transform: rotate(-90deg); 

for the speed , you can set the jquery .animation duration to certain amount.

You can try using parentheses around the OR expressions to make sure your query is interpreted correctly, or more concisely, use IN:

SELECT ads.*, location.county 
FROM ads
LEFT JOIN location ON location.county = ads.county_id
WHERE ads.published = 1 
AND ads.type = 13
AND ads.county_id IN (2,5,7,9)

The title attribute is meant to give more information. It's not useful for SEO so it's never a good idea to have the same text in the title and alt which is meant to describe the image or input is vs. what it does. for instance:

<button title="prints out hello world">Sample Buttons</button>

<img title="Hms beagle in the straits of magellan" alt="HMS Beagle painting" src="hms-beagle.jpg" />

The title attribute will make a tool tip, but it will be controlled by the browser as far as where it shows up and what it looks like. If you want more control there are third party jQuery options, many css templates such as Bootstrap have built in solutions, and you can also write a simple css solution if you want. check out this w3schools solution.

If your having trouble connecting, most likely the problem is that you haven't yet enabled the TCP/IP listener on port 1433. A quick "netstat -an" command will tell you if its listening. By default, SQL server doesn't enable this after installation.

Also, you need to set a password on the "sa" account and also ENABLE the "sa" account (if you plan to use that account to connect with).

Obviously, this also means you need to enable "mixed mode authentication" on your MSSQL node.

This works, as long as you remove the height attribute from the table.

<table id="content" border="0px" cellspacing="0px" cellpadding="0px">
  <tr><td height='9px' bgcolor="#990000">Upper</td></tr>
  <tr><td height='100px' bgcolor="#990099">Lower</td></tr>
</table>

There's now a simpler way with .NET Standard or .NET Core:

var client = new HttpClient();
var response = await client.PostAsync(uri, myRequestObject, new JsonMediaTypeFormatter());

NOTE: In order to use the JsonMediaTypeFormatter class, you will need to install the Microsoft.AspNet.WebApi.Client NuGet package, which can be installed directly, or via another such as Microsoft.AspNetCore.App.

Using this signature of HttpClient.PostAsync, you can pass in any object and the JsonMediaTypeFormatter will automatically take care of serialization etc.

With the response, you can use HttpContent.ReadAsAsync<T> to deserialize the response content to the type that you are expecting:

var responseObject = await response.Content.ReadAsAsync<MyResponseType>();

A good friend and colleague of mine showed me how you can also use an IF block with SQL functions OBJECT_ID and COLUMNPROPERTY in SQL SERVER 2005+ to check for a column. You can use something similar to the following:

You can see for yourself here

IF (OBJECT_ID(N'[dbo].[myTable]') IS NOT NULL AND
    COLUMNPROPERTY( OBJECT_ID(N'[dbo].[myTable]'), 'ThisColumnDoesNotExist', 'ColumnId') IS NULL)
BEGIN
    SELECT 'Column does not exist -- You can add TSQL to add the column here'
END

Update (2017/01/05):

GitHub has published an update that allows you now to search within commit messages from within their UI. See blog post for more information.

I had the same question and contacted someone GitHub yesterday:

Since they switched their search engine to Elasticsearch it's not possible to search for commit messages using the GitHub UI. But that feature is on the team's wishlist.

Unfortunately there's no release date for that function right now.

find /path -type f \( -iname "*.jpg" -o -name "*.jpeg" -o -iname "*gif" \)

If you don't want to hardcode the domain name, you can use this redirect block. The domain without the leading www is saved as variable $domain which can be reused in the redirect statement.

server {
    ...
    # Redirect www to non-www
    if ( $host ~ ^www\.(?<domain>.+) ) {
       rewrite ^/(.*)$ $scheme://$domain/$1;
    }
}

REF: Redirecting a subdomain with a regular expression in nginx

You can use static class or Singleton pattern.

Consider using jQuery. Life is much easier with:

$('body').hide(); $('body1').show();

=IF(CR<=10, "RED", if(CR<50, "YELLOW", if(CR<101, "GREEN")))

CR = ColRow (Cell) This is an example. In this example when value in Cell is less then or equal to 10 then RED word will appear on that cell. In the same manner other if conditions are true if first if is false.

Remove "strictNullChecks": true from "compilerOptions" or set it to false in the tsconfig.json file of your Ng app. These errors will go away like anything and your app would compile successfully.

Disclaimer: This is just a workaround. This error appears only when the null checks are not handled properly which in any case is not a good way to get things done.

Just add:

namespace System.IO
{
    public static class FileInfoExtensions
    {
        public static void Rename(this FileInfo fileInfo, string newName)
        {
            fileInfo.MoveTo(Path.Combine(fileInfo.Directory.FullName, newName));
        }
    }
}

And then...

FileInfo file = new FileInfo("c:\test.txt");
file.Rename("test2.txt");

I know I told babay in 2012 that I thought it was unlikely that someone wouldn't realize that they weren't on a branch and commit. This just happened to me, so I guess I have to admit that I was wrong, but considering that it took until 2016 for this to happen to me, you could argue that it is in fact unlikely.

Anyway, creating a new branch is overkill in my opinion. All you have to do is:

git checkout some-branch
git merge commit-sha

If you didn't copy the commit-sha before checking out the other branch, you can easily find it by running:

git reflog

If you have ArrayList then convert into Array[Object]

ArrayList<String> list = new ArrayList<String>();
PreparedStatement pstmt = 
            conn.prepareStatement("select * from employee where id in (?)");
Array array = conn.createArrayOf("VARCHAR", list.toArray());
pstmt.setArray(1, array);
ResultSet rs = pstmt.executeQuery();

    },

        },
    }
})

coalesce is supported in both Oracle and SQL Server and serves essentially the same function as nvl and isnull. (There are some important differences, coalesce can take an arbitrary number of arguments, and returns the first non-null one. The return type for isnull matches the type of the first argument, that is not true for coalesce, at least on SQL Server.)

List<Object> list = new ArrayList<>();
          list.add(1);
          list.add("1");

As the return type of ArrayList is object, you can add any type of data to ArrayList but it is not a good practice to use ArrayList because there is unnecessary boxing and unboxing.

You can set the row height by code

dataGridView.RowTemplate.Height = 35;

or by property panel

You have a JSON string, not an object. Tell jQuery that you expect a JSON response and it will parse it for you. Either use $.getJSON instead of $.get, or pass the dataType argument to $.get:

$.get(
    'index.php?r=admin/post/ajax',
    {"parentCatId":parentCatId},
    function(data){                     
        $.each(data, function(key, value){
            console.log(key + ":" + value)
        })
    },
    'json'
);

Google's Guava API also has .join(), although (as should be obvious with the other replies), Apache Commons is pretty much the standard here.

You can use this one also (sets a special listener to be called when an action is performed on the EditText), it works both for DONE and RETURN:

max.setOnEditorActionListener(new OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
            if ((event != null && (event.getKeyCode() == KeyEvent.KEYCODE_ENTER)) || (actionId == EditorInfo.IME_ACTION_DONE)) {
                Log.i(TAG,"Enter pressed");
            }    
            return false;
        }
    });

What's the difference between an RDD's map and mapPartitions method?

The method map converts each element of the source RDD into a single element of the result RDD by applying a function. mapPartitions converts each partition of the source RDD into multiple elements of the result (possibly none).

And does flatMap behave like map or like mapPartitions?

Neither, flatMap works on a single element (as map) and produces multiple elements of the result (as mapPartitions).

This will delete all the lines with pattern, and report how many deleted. Undo to get them back after.

I’d really suggest that people who encounter this problem go and find a third party database comparison tool.

Reason – these tools save a lot of time and make the process less error prone.

I’ve used comparison tools from ApexSQL (Diff and Data Diff) but you can’t go wrong with other tools marc_s and Marina Nastenko already pointed out.

If you’re absolutely sure that you are only going to compare tables once then SQL is fine but if you’re going to need this from time to time you’ll be better off with some 3rd party tool.

If you don’t have budget to buy it then just use it in trial mode to get the job done.

I hope new readers will find this useful even though it’s a late answer…

You can try this:

SELECT EXTRACT(YEAR FROM field) FROM table WHERE id=1

If you're trying to connect using "SQL Server Authentication" then you may want to modify your server authentication:

Within the Microsoft SQL Server Management Studio in the object explorer:

1. Right click on the server and click Properties

2. Go to the Security page

3. Under Server authentication choose the SQL Server and Windows Authentication mode radio button

4. Click OK

5. Restart SQL Services

Sorry about the confusion, this should be the correct approach. Do you want only to capture 'bad' only, not things like 'good'; Or just any non-numerical values?

I got this error message while running tests in Visual Studio: Firefox simply wouldn't load and I got OP's error message.

I manually opened Firefox and found out that it needed to update itself (it did so before loading). Once finished I reran the test suite and Firefox showed up nicely, the tests were properly ran. If you get this error all of a sudden please try this answer before updating anything on your machine.

In my case it was happening because I had not typed a variable.

So I created the Search interface

export interface Search {
  term: string;
  ...
}

I changed that

searchList = [];

for that and it worked

searchList: Search[];

I recommend using the python bindings to OpenImageIO, it's the standard for dealing with various image formats in the vfx world. I've ovten found it more reliable in reading various compression types compared to PIL.

import OpenImageIO as oiio

To get a deterministic value for the day of week for a given date you could use a combination of DATEPART() and @@datefirst. Otherwise your dependent on the settings on the server.

Check out the following site for a better solution: MS SQL: Day of Week

The day of week will then be in the range 0 to 6, where 0 is Sunday, 1 is Monday, etc. Then you can use a simple case statement to return the correct weekday name.

Swift 4.2

In Swift 4.2 the name of table is a little changed.

    func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
        let view = UIView(frame: CGRect(x: 0, y: 0, width: tableView.frame.size.width, height: 18))
        let label = UILabel(frame: CGRect(x: 10, y: 5, width: tableView.frame.size.width, height: 18))
        label.font = UIFont.systemFont(ofSize: 14)
        label.text = list.objectAtIndex(section) as! String
        view.addSubview(label)
        view.backgroundColor = UIColor.gray // Set your background color

        return view
    }

One pitfall I ran into was a parent element having the 'overflow' attribute set to 'auto'. This negates child div elements with the page-break-inside attribute in the print version. Otherwise, page-break-inside: avoid works fine on Chrome for me.

It's a little on the cumbersome side, but I believe this should work (without the extra join). This assumes that you can choose a character that will never appear in the field in question, to act as a separator.

You can do it without nesting the select, but I find this a little cleaner that having four references to SYS_CONNECT_BY_PATH.

select id, 
       parent_id, 
       case 
         when lvl <> 1 
         then substr(name_path,
                     instr(name_path,'|',1,lvl-1)+1,
                     instr(name_path,'|',1,lvl)
                      -instr(name_path,'|',1,lvl-1)-1) 
         end as name 
from (
  SELECT id, parent_id, sys_connect_by_path(name,'|') as name_path, level as lvl
  FROM tbl 
  START WITH id = 1 
  CONNECT BY PRIOR id = parent_id)

Checkout intent properties like no history , clear back stack etc ... Intent.setFlags

Intent mStartActivity = new Intent(HomeActivity.this, SplashScreen.class);
int mPendingIntentId = 123456;
PendingIntent mPendingIntent = PendingIntent.getActivity(HomeActivity.this, mPendingIntentId, mStartActivity,
PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager mgr = (AlarmManager) HomeActivity.this.getSystemService(Context.ALARM_SERVICE);
mgr.set(AlarmManager.RTC, System.currentTimeMillis() + 100, mPendingIntent);
System.exit(0);

You could also change the viewChild 'type' to NgForm as in:

@ViewChild('loginForm') loginForm: NgForm;

And then reference your controls in the same way @Julia mentioned:

 private login(formData: any): void {
    this.authService.login(formData).subscribe(res => {
      alert(`Congrats, you have logged in. We don't have anywhere to send you right now though, but congrats regardless!`);
    }, error => {
      this.loginFailed = true; // This displays the error message, I don't really like this, but that's another issue.

      this.loginForm.controls['email'].setErrors({ 'incorrect': true});
      this.loginForm.controls['password'].setErrors({ 'incorrect': true});
    });
  }

Setting the Errors to null will clear out the errors on the UI:

this.loginForm.controls['email'].setErrors(null);

You want the --stat option of git diff, or if you're looking to parse this in a script, the --numstat option.

git diff --stat <commit-ish> <commit-ish>

--stat produces the human-readable output you're used to seeing after merges; --numstat produces a nice table layout that scripts can easily interpret.

I somehow missed that you were looking to do this on multiple commits at the same time - that's a task for git log. Ron DeVera touches on this, but you can actually do a lot more than what he mentions. Since git log internally calls the diff machinery in order to print requested information, you can give it any of the diff stat options - not just --shortstat. What you likely want to use is:

git log --author="Your name" --stat <commit1>..<commit2>

but you can use --numstat or --shortstat as well. git log can also select commits in a variety other ways - have a look at the documentation. You might be interested in things like --since (rather than specifying commit ranges, just select commits since last week) and --no-merges (merge commits don't actually introduce changes), as well as the pretty output options (--pretty=oneline, short, medium, full...).

Here's a one-liner to get total changes instead of per-commit changes from git log (change the commit selection options as desired - this is commits by you, from commit1 to commit2):

git log --numstat --pretty="%H" --author="Your Name" commit1..commit2 | awk 'NF==3 {plus+=$1; minus+=$2} END {printf("+%d, -%d\n", plus, minus)}'

(you have to let git log print some identifying information about the commit; I arbitrarily chose the hash, then used awk to only pick out the lines with three fields, which are the ones with the stat information)

The BIT datatype is generally used to store boolean values (0 for false, 1 for true).

I generally like the shorthand version:

if (!!wlocation) { window.location = wlocation; }

This isn't possible with ruby currently. You can't pass 'empty' attributes to methods. The closest you can get is to pass nil:

ldap_get(base_dn, filter, nil, X)

However, this will set the scope to nil, not LDAP::LDAP_SCOPE_SUBTREE.

What you can do is set the default value within your method:

def ldap_get(base_dn, filter, scope = nil, attrs = nil)
  scope ||= LDAP::LDAP_SCOPE_SUBTREE
  ... do something ...
end

Now if you call the method as above, the behaviour will be as you expect.

There's an additional factor here; in addition to the java executables that the java installation puts wherever you ask it to put them, on windows, the java installer also puts copies of some of those executables in your windows system32 directory, so you will likely be using which every java executable was installed most recently.

To solve this problem please follow the steps below:

1. Download the maven zip file from http://maven.apache.org/download.cgi
2. Extract the maven zip file
3. Open the environment variable and in user variable section click on new button and make a variable called MAVEN_HOME and assign it the value of bin path of extracted maven zip
4. Now in System Variable click on Path and click on Edit button --> Now Click on New button and paste the bin path of maven zip
5. Now click on OK button
6. Open CMD and type mvn -version
7. Installed Maven version will be displayed and your setup is completed

Then try moving it to a sub folder under the C:, but verify that the user has full rights on the folder your use.

Your Call works if it were a Table Valued Function. Since its a scalar function, you need to call it like:

SELECT dbo.fn_HomePageSlider(9, 3025) AS MyResult

import csv
import json
csvfile = csv.DictReader('filename.csv', 'r'))
output =[]
for each in csvfile:
    row ={}
    row['FirstName'] = each['FirstName']
    row['LastName']  = each['LastName']
    row['IDNumber']  = each ['IDNumber']
    row['Message']   = each['Message']
    output.append(row)
json.dump(output,open('filename.json','w'),indent=4,sort_keys=False)

With GNU Parallel you can do:

cat a.txt | parallel 'command1 {}; command2 {}; ...; '

I guess this is essentially putting it in a string, but this avoids the rounding error:

import decimal

def display(x):
    digits = 15
    temp = str(decimal.Decimal(str(x) + '0' * digits))
    return temp[:temp.find('.') + digits + 1]

I can see that you want to write you own short javascript for this, but have you considered to use Frameworks for HTML manipulation instead? jQuery is my prefered tool for such a task, eventhough its an overkill for your current question as it has SO many extra functionalities.

Have a look at jQuery here

A command-line process such cmd.exe or mysql.exe will usually read (and execute) whatever you (the user) type in (at the keyboard).

To mimic that, I think you want to use the RedirectStandardInput property: http://msdn.microsoft.com/en-us/library/system.diagnostics.processstartinfo.redirectstandardinput.aspx

The right thing would be to use a "if defined" statement, which is used to test for the existence of a variable. For example:

IF DEFINED somevariable echo Value exists

In this particular case, the negative form should be used:

IF NOT DEFINED somevariable echo Value missing

PS: the variable name should be used without "%" caracters.

Maybe I'm misunderstanding, but if you want truly readonly Ids why not use an actual readonly field?

public class Person
{
   public Person(int id)
   {
      m_id = id;
   }

   readonly int m_id;
   public int Id { get { return m_id; } }
}

Yes, you will have no problems using:

if (BuildConfig.DEBUG) {
   //It's not a release version.
}

Unless you are importing the wrong BuildConfig class. Make sure you are referencing your project's BuildConfig class, not from any of your dependency libraries.

You have a numpy array of strings, not floats. This is what is meant by dtype('<U9') -- a little endian encoded unicode string with up to 9 characters.

try:

return sum(np.asarray(listOfEmb, dtype=float)) / float(len(listOfEmb))

However, you don't need numpy here at all. You can really just do:

return sum(float(embedding) for embedding in listOfEmb) / len(listOfEmb)

Or if you're really set on using numpy.

return np.asarray(listOfEmb, dtype=float).mean()

File.exist?("directory")

Dir[] returns an array, so it will never be nil. If you want to do it your way, you could do

Dir["directory"].empty?

which will return true if it wasn't found.

Just to add some specific settings, I had a similar setup (with Apache 2.0.63 reverse proxying onto Tomcat 5.0.27).

For certain URLs the Tomcat server could take perhaps 20 minutes to return a page.

I ended up modifying the following settings in the Apache configuration file to prevent it from timing out with its proxy operation (with a large over-spill factor in case Tomcat took longer to return a page):

Timeout 5400
ProxyTimeout 5400

Some backgound

ProxyTimeout alone wasn't enough. Looking at the documentation for Timeout I'm guessing (I'm not sure) that this is because while Apache is waiting for a response from Tomcat, there is no traffic flowing between Apache and the Browser (or whatever http client) - and so Apache closes down the connection to the browser.

I found that if I left the Timeout setting at its default (300 seconds), then if the proxied request to Tomcat took longer than 300 seconds to get a response the browser would display a "502 Proxy Error" page. I believe this message is generated by Apache, in the knowledge that it's acting as a reverse proxy, before it closes down the connection to the browser (this is my current understanding - it may be flawed).

The proxy error page says:

Proxy Error

The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET.

Reason: Error reading from remote server

...which suggests that it's the ProxyTimeout setting that's too short, while investigation shows that Apache's Timeout setting (timeout between Apache and the client) that also influences this.

The Code Runner extension has a setting "Clear previous output", which is what I need 95% of the time.

File > Preferences > Settings > (search for "output") > Code-runner: Clear previous output

The remaining few times I will disable the setting and use the "Clear output" button (top right of the output pane) to selectively clear accumulated output.

This is in Visual Studio Code 1.33.1 with Code Runner 0.9.8.

(Setting the keybinding for Ctrl+k did not work for me, presumably because some extension has defined "chords" beginning with Ctrl-k. But "Clear previous output" was actually a better option for me.)

You can use hostname command :

ipaddr=$(hostname -I)

-i, --ip-address: Display the IP address(es) of the host. Note that this works only if the host name can be resolved.

-I, --all-ip-addresses: Display all network addresses of the host. This option enumerates all configured addresses on all network interfaces. The loopback interface and IPv6 link-local addresses are omitted. Contrary to option -i, this option does not depend on name resolution. Do not make any assumptions about the order of the output.

It is well defined behaviour. You cannot get the old value for a mutated object. That's because both the newVal and oldVal refer to the same object. Vue will not keep an old copy of an object that you mutated.

Had you replaced the object with another one, Vue would have provided you with correct references.

Read the Note section in the docs. (vm.$watch)

More on this here and here.

I made a script to make the command line cursor move on mouse click :

1. Enable xterm mouse tracking reporting
2. Set readline bindings to consume the escape sequence generated by clicks

It can be found on github

Will work if echo -e "\e[?1000;1006;1015h" # Enable tracking print escape sequences on terminal when clicking with mouse

rurban's fork of SMHasher (the original SMHasher seems abandoned) has hardware CRC32 support. The changes were added before the initial commit, but try comparing the new CMakeLists.txt and the old one (which doesn't mention SSE at all).

The best option is probably Intel's zlib fork with PCLMULQDQ support described in this paper. This library also has the SSE 4.2 optimizations.

If you don't need portability and you're on Linux, you can use the kernel's implementation (which is hardware accelerated if available): https://stackoverflow.com/a/11156040/309483

Why do you need to state both 'x' and 'y' before the ':'?

Because a lambda is (conceptually) the same as a function, just written inline. Your example is equivalent to

def f(x, y) : return x + y

just without binding it to a name like f.

Also how do you make it return multiple arguments?

The same way like with a function. Preferably, you return a tuple:

lambda x, y: (x+y, x-y)

Or a list, or a class, or whatever.

The thing with self.entry_1.bind should be answered by Demosthenex.

In Java 8

To create a non-empty list of fixed size (operations like add, remove, etc., are not supported):

List<Integer> list = Arrays.asList(1, 2); // but, list.set(...) is supported

To create a non-empty mutable list:

List<Integer> list = new ArrayList<>(Arrays.asList(3, 4));

In Java 9

Using a new List.of(...) static factory methods:

List<Integer> immutableList = List.of(1, 2);

List<Integer> mutableList = new ArrayList<>(List.of(3, 4));

In Java 10

Using the Local Variable Type Inference:

var list1 = List.of(1, 2);

var list2 = new ArrayList<>(List.of(3, 4));

var list3 = new ArrayList<String>();

And follow best practices...

Don't use raw types

Since Java 5, generics have been a part of the language - you should use them:

List<String> list = new ArrayList<>(); // Good, List of String

List list = new ArrayList(); // Bad, don't do that!

Program to interfaces

For example, program to the List interface:

List<Double> list = new ArrayList<>();

Instead of:

ArrayList<Double> list = new ArrayList<>(); // This is a bad idea!

another example following @jake stayman:

{% for key, item in row.divs %}
    {% if (key not in [1,2,9]) %} // eliminate element 1,2,9
        <li>{{ item }}</li>
    {% endif %}
{% endfor %}

For ICS I´ve implemented your code and made a class that extends AsyncTask. I hope you appreciate it! Thanks for your code and solution.

public class UpdateApp extends AsyncTask<String,Void,Void>{
    private Context context;
    public void setContext(Context contextf){
        context = contextf;
    }

    @Override
    protected Void doInBackground(String... arg0) {
        try {
            URL url = new URL(arg0[0]);
            HttpURLConnection c = (HttpURLConnection) url.openConnection();
            c.setRequestMethod("GET");
            c.setDoOutput(true);
            c.connect();

            String PATH = "/mnt/sdcard/Download/";
            File file = new File(PATH);
            file.mkdirs();
            File outputFile = new File(file, "update.apk");
            if(outputFile.exists()){
                outputFile.delete();
            }
            FileOutputStream fos = new FileOutputStream(outputFile);

            InputStream is = c.getInputStream();

            byte[] buffer = new byte[1024];
            int len1 = 0;
            while ((len1 = is.read(buffer)) != -1) {
                fos.write(buffer, 0, len1);
            }
            fos.close();
            is.close();

            Intent intent = new Intent(Intent.ACTION_VIEW);
            intent.setDataAndType(Uri.fromFile(new File("/mnt/sdcard/Download/update.apk")), "application/vnd.android.package-archive");
            intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // without this flag android returned a intent error!
            context.startActivity(intent);


        } catch (Exception e) {
            Log.e("UpdateAPP", "Update error! " + e.getMessage());
        }
        return null;
    }
}   

To use it, in your main activity call by this way:

atualizaApp = new UpdateApp();
atualizaApp.setContext(getApplicationContext());
atualizaApp.execute("http://serverurl/appfile.apk");

if you just want to set the spacing a simple one liner with minimal boilerplate:

plt.gca().xaxis.set_major_locator(plt.MultipleLocator(1))

also works easily for minor ticks:

plt.gca().xaxis.set_minor_locator(plt.MultipleLocator(1))

a bit of a mouthfull, but pretty compact

Hat tip to Adam Bien if you don't want to use createQuery with a String and want type safety:

 @PersistenceContext
 EntityManager em;

 public List<ConfigurationEntry> allEntries() {
        CriteriaBuilder cb = em.getCriteriaBuilder();
        CriteriaQuery<ConfigurationEntry> cq = cb.createQuery(ConfigurationEntry.class);
        Root<ConfigurationEntry> rootEntry = cq.from(ConfigurationEntry.class);
        CriteriaQuery<ConfigurationEntry> all = cq.select(rootEntry);
        TypedQuery<ConfigurationEntry> allQuery = em.createQuery(all);
        return allQuery.getResultList();
 }

Although this post is post is tagged for Windows, it is relevant question on OS X that I have not seen answers for elsewhere. Here are steps to create a self-signed cert for localhost on OS X:

# Use 'localhost' for the 'Common name'
openssl req -x509 -sha256 -nodes -newkey rsa:2048 -days 365 -keyout localhost.key -out localhost.crt

# Add the cert to your keychain
open localhost.crt

In Keychain Access, double-click on this new localhost cert. Expand the arrow next to "Trust" and choose to "Always trust". Chrome and Safari should now trust this cert. For example, if you want to use this cert with node.js:

var options = {
    key: fs.readFileSync('/path/to/localhost.key').toString(),
    cert: fs.readFileSync('/path/to/localhost.crt').toString(),
    ciphers: 'ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES256-SHA384',
    honorCipherOrder: true,
    secureProtocol: 'TLSv1_2_method'
};

var server = require('https').createServer(options, app);

if you're using MS Sql, I have wrote 2 extension methods to support the % character for wildcard search. (LinqKit is required)

public static class ExpressionExtension
{
    public static Expression<Func<T, bool>> Like<T>(Expression<Func<T, string>> expr, string likeValue)
    {
        var paramExpr = expr.Parameters.First();
        var memExpr = expr.Body;

        if (likeValue.Replace("%", string.Empty).Length == 0)
        {
            return PredicateBuilder.True<T>();
        }

        likeValue = Regex.Replace(likeValue, "%+", "%");

        if (likeValue.Length > 2 && likeValue.Substring(1, likeValue.Length - 2).Contains('%'))

        }
        else
        {

            return Expression.Lambda<Func<T, bool>>(startsExpr, paramExpr);
        }
    }

    public static Expression<Func<T, bool>> AndLike<T>(this Expression<Func<T, bool>> predicate, Expression<Func<T, string>> expr, string likeValue)
    {
        var andPredicate = Like(expr, likeValue);
        if (andPredicate != null)
        {
            predicate = predicate.And(andPredicate.Expand());
        }
        return predicate;
    }

    public static Expression<Func<T, bool>> OrLike<T>(this Expression<Func<T, bool>> predicate, Expression<Func<T, string>> expr, string likeValue)
    {
        var orPredicate = Like(expr, likeValue);
        if (orPredicate != null)
        {
            predicate = predicate.Or(orPredicate.Expand());
        }
        return predicate;

}

usage

var orPredicate = PredicateBuilder.False<People>();
orPredicate = orPredicate.OrLike(per => per.Name, "He%llo%");
orPredicate = orPredicate.OrLike(per => per.Name, "%Hi%");

var predicate = PredicateBuilder.True<People>();
predicate = predicate.And(orPredicate.Expand());
predicate = predicate.AndLike(per => per.Status, "%Active");

var list = dbContext.Set<People>().Where(predicate.Expand()).ToList();    

in ef6 and it should translate to

....
from People per
where (
    patindex(@p__linq__0, per.Name) <> 0
    or per.Name like @p__linq__1 escape '~'
) and per.Status like @p__linq__2 escape '~'

', @p__linq__0 = '%He%llo%', @p__linq__1 = '%Hi%', @p__linq_2 = '%Active'

The TextEncoder and TextDecoder Encoding API will let you both encode and decode UTF-8 easily (using typed arrays):

const encoded = new TextEncoder().encode("Ge?a s?? ??sµe");
const decoded = new TextDecoder().decode(encoded);

console.log(encoded, decoded);

Browser support isn't too bad, and there's a polyfill that should work in IE11 and older versions of Edge.

Older versions of TextEncoder supported other different encodings as a string constructor parameter argument, but since Firefox 48 and Chrome 53 this is no-longer supported and TextEncoder and TextDecoder support only UTF-8.

So this will no-longer work in modern web-browsers used since 2016:

new TextDecoder("shift-jis").decode(new Uint8Array(textbuffer))

The typical use is

void* ret = NULL;
pthread_t tid = something; /// change it suitably
if (pthread_join (tid, &ret)) 
   handle_error();
// do something with the return value ret

CGI is a mechanism whereby an external program is called by the web server in order to handle a request, with environment variables and standard input being used to feed the request data to the program. The exact language the external program is written in does not matter, although it is easier to write CGI programs in some languages versus others.

Since CGI scripts need execute permissions, httpd by default only allows CGI programs in the cgi-bin directory to be run for (possibly now misguided) security purposes.

Most PHP scripts run in the web server process via mod_php. This is not CGI.

CGI is slow since the program (and related interpreter) must be started up per request. Modern alternatives are embedded execution, used by mod_php, and long-running processes, used by FastCGI. A given language may have its own way of implementing those mechanisms, so be sure to ask around before resorting to CGI.

To drop a particular database, you can do this on rails console:

$rails console
Loading development environment
1.9.3 > ActiveRecord::Migration.drop_table(:<table_name>)
1.9.3 > exit

And then migrate DB again

$bundle exec rake db:migrate 

<input type="text" />
<script>
$("input:text").change(function() {
    var value=$("input:text").val();
    alert(value);
});
</script>

use .val() to get value of the element (jquery method), $("input:text") this selector to select your input, .change() to bind an event handler to the "change" JavaScript event.

In angular 7+ which has built-in pipe

See the official documentation (http://docs.oracle.com/cd/B19306_01/server.102/b14200/sql_elements001.htm#i54330)

Variable-length character string having maximum length size bytes or characters. Maximum size is 4000 bytes or characters, and minimum is 1 byte or 1 character. You must specify size for VARCHAR2. BYTE indicates that the column will have byte length semantics; CHAR indicates that the column will have character semantics.

But in Oracle Databast 12c maybe 32767 (http://docs.oracle.com/database/121/SQLRF/sql_elements001.htm#SQLRF30020)

Variable-length character string having maximum length size bytes or characters. You must specify size for VARCHAR2. Minimum size is 1 byte or 1 character. Maximum size is: 32767 bytes or characters if MAX_STRING_SIZE = EXTENDED 4000 bytes or characters if MAX_STRING_SIZE = STANDARD

There's a pretty good explanation of first level caching on the Streamline Logic blog.

Basically, first level caching happens on a per session basis where as second level caching can be shared across multiple sessions.

It is better to also escape SQL reserved words. For example:

function ms_escape_string($data) {
    if (!isset($data) or empty($data))
        return '';

    if (is_numeric($data))
        return $data;

    $non_displayables = array(
        '/%0[0-8bcef]/',        // URL encoded 00-08, 11, 12, 14, 15
        '/%1[0-9a-f]/',         // url encoded 16-31
        '/[\x00-\x08]/',        // 00-08
        '/\x0b/',               // 11
        '/\x0c/',               // 12
        '/[\x0e-\x1f]/',        // 14-31
        '/\27/'
    );
    foreach ($non_displayables as $regex)
        $data = preg_replace( $regex, '', $data);
    $reemplazar = array('"', "'", '=');
    $data = str_replace($reemplazar, "*", $data);
    return $data;
}

That means that the definition of your function is not present in your program. You forgot to add that one.cpp to your program.

What "to add" means in this case depends on your build environment and its terminology. In MSVC (since you are apparently use MSVC) you'd have to add one.cpp to the project.

In more practical terms, applicable to all typical build methodologies, when you link you program, the object file created form one.cpp is missing.

If your web application is configured to impersonate a client, then using a trusted connection will potentially have a negative performance impact. This is because each client must use a different connection pool (with the client's credentials).

Most web applications don't use impersonation / delegation, and hence don't have this problem.

See this MSDN article for more information.

There is an Excel file with regexps here. You can easily "convert" it to XML and you will be able to determine country by the full phone number.

UPD: The file that I referenced 4 years ago is no longer accessible. I would recommend using Google's libphonenumber.

The answer to Extract code country from phone number [libphonenumber] will show you the proper way to receive country code from a phone number.

If you want to change one specific onclick event with jQuery, you better use the functions .on() and .off() with a namespace (see documentation).

Use .on() to create your event and .off() to remove it. You can also create a global object like g_specific_events_set = {}; to avoid duplicates:

$('#alert').click(function()_x000D_
{_x000D_
    alert('First alert!');_x000D_
});_x000D_

g_specific_events_set = {};_x000D_

Set the second function parameter to true if you require an associative array

Some versions of php require a 2nd paramter of true if you require an associative array

$json  = '[{"var1":"9","var2":"16","var3":"16"},{"var1":"8","var2":"15","var3":"15"}]';
$array = json_decode( $json, true );

Comment as an answer:

if (timetime[0].value)

This works because any variable in JS can be evaluated as a boolean, so this will generally catch things that are empty, null, or undefined.

• START_STICKY: It will restart the service in case if it terminated and the Intent data which is passed to the onStartCommand() method is NULL. This is suitable for the service which are not executing commands but running independently and waiting for the job.
• START_NOT_STICKY: It will not restart the service and it is useful for the services which will run periodically. The service will restart only when there are a pending startService() calls. It’s the best option to avoid running a service in case if it is not necessary.
• START_REDELIVER_INTENT: It’s same as STAR_STICKY and it recreates the service, call onStartCommand() with last intent that was delivered to the service.

I think that SYSLOG levels NOTICE and ALERT/EMERGENCY are largely superfluous for application-level logging - while CRITICAL/ALERT/EMERGENCY may be useful alert levels for an operator that may trigger different actions and notifications, to an application admin it's all the same as FATAL. And I just cannot sufficiently distinguish between being given a notice or some information. If the information is not noteworthy, it's not really information :)

I like Jay Cincotta's interpretation best - tracing your code's execution is something very useful in tech support, and putting trace statements into the code liberally should be encouraged - especially in combination with a dynamic filtering mechanism for logging the trace messages from specific application components. However DEBUG level to me indicates that we're still in the process of figuring out what's going on - I see DEBUG level output as a development-only option, not as something that should ever show up in a production log.

There is however a logging level that I like to see in my error logs when wearing the hat of a sysadmin as much as that of tech support, or even developer: OPER, for OPERATIONAL messages. This I use for logging a timestamp, the type of operation invoked, the arguments supplied, possibly a (unique) task identifier, and task completion. It's used when e.g. a standalone task is fired off, something that is a true invocation from within the larger long-running app. It's the sort of thing I want always logged, no matter whether anything goes wrong or not, so I consider the level of OPER to be higher than FATAL, so you can only turn it off by going to totally silent mode. And it's much more than mere INFO log data - a log level often abused for spamming logs with minor operational messages of no historical value whatsoever.

As the case dictates this information may be directed to a separate invocation log, or may be obtained by filtering it out of a large log recording more information. But it's always needed, as historical info, to know what was being done - without descending to the level of AUDIT, another totally separate log level that has nothing to do with malfunctions or system operation, doesn't really fit within the above levels (as it needs its own control switch, not a severity classification) and which definitely needs its own separate log file.

I didn't like any of the above answers because none of them correctly handle the mixture of strings/numbers that can be values in TypeScript enums.

The following function follows the semantics of TypeScript enums to give a proper Map of keys to values. From there, getting an array of objects or just the keys or just the values is trivial.

/**
 * Converts the given enum to a map of the keys to the values.
 * @param enumeration The enum to convert to a map.
 */
function enumToMap(enumeration: any): Map<string, string | number> {
  const map = new Map<string, string | number>();
  for (let key in enumeration) {
      //TypeScript does not allow enum keys to be numeric
      if (!isNaN(Number(key))) continue;

      const val = enumeration[key] as string | number;

      //TypeScript does not allow enum value to be null or undefined
      if (val !== undefined && val !== null)
          map.set(key, val);
  }

  return map;
}

Example Usage:

enum Dog {
    Rover = 1,
    Lassie = "Collie",
    Fido = 3,
    Cody = "Mutt",
}

let map = enumToMap(Dog); //Map of keys to values

let objs = Array.from(map.entries()).map(m => ({id: m[1], name: m[0]})); //Objects as asked for in OP
let entries = Array.from(map.entries()); //Array of each entry
let keys = Array.from(map.keys()); //An array of keys
let values = Array.from(map.values()); //An array of values

I'll also point out that the OP is thinking of enums backwards. The "key" in the enum is technically on the left hand side and the value is on the right hand side. TypeScript allows you to repeat the values on the RHS as much as you'd like.

If you need a .dll file that is not on the path or on the application's location, then I don't think you can do just that, because DllImport is an attribute, and attributes are only metadata that is set on types, members and other language elements.

An alternative that can help you accomplish what I think you're trying, is to use the native LoadLibrary through P/Invoke, in order to load a .dll from the path you need, and then use GetProcAddress to get a reference to the function you need from that .dll. Then use these to create a delegate that you can invoke.

To make it easier to use, you can then set this delegate to a field in your class, so that using it looks like calling a member method.

EDIT

Here is a code snippet that works, and shows what I meant.

class Program
{
    static void Main(string[] args)
    {
        var a = new MyClass();
        var result = a.ShowMessage();
    }
}

class FunctionLoader
{
    [DllImport("Kernel32.dll")]
    private static extern IntPtr LoadLibrary(string path);

    [DllImport("Kernel32.dll")]
    private static extern IntPtr GetProcAddress(IntPtr hModule, string procName);

    public static Delegate LoadFunction<T>(string dllPath, string functionName)
    {
        var hModule = LoadLibrary(dllPath);
        var functionAddress = GetProcAddress(hModule, functionName);
        return Marshal.GetDelegateForFunctionPointer(functionAddress, typeof (T));
    }
}

public class MyClass
{
    static MyClass()
    {
        // Load functions and set them up as delegates
        // This is just an example - you could load the .dll from any path,
        // and you could even determine the file location at runtime.
        MessageBox = (MessageBoxDelegate) 
            FunctionLoader.LoadFunction<MessageBoxDelegate>(
                @"c:\windows\system32\user32.dll", "MessageBoxA");
    }

    private delegate int MessageBoxDelegate(
        IntPtr hwnd, string title, string message, int buttons); 

    /// <summary>
    /// This is the dynamic P/Invoke alternative
    /// </summary>
    static private MessageBoxDelegate MessageBox;

    /// <summary>
    /// Example for a method that uses the "dynamic P/Invoke"
    /// </summary>
    public int ShowMessage()
    {
        // 3 means "yes/no/cancel" buttons, just to show that it works...
        return MessageBox(IntPtr.Zero, "Hello world", "Loaded dynamically", 3);
    }
}

Note: I did not bother to use FreeLibrary, so this code is not complete. In a real application, you should take care to release the loaded modules to avoid a memory leak.

No. It's very easy to check.

public class Catch {
    public static void main(String[] args) {
        try {
            throw new java.io.IOException();
        } catch (java.io.IOException exc) {
            System.err.println("In catch IOException: "+exc.getClass());
            throw new RuntimeException();
        } catch (Exception exc) {
            System.err.println("In catch Exception: "+exc.getClass());
        } finally {
            System.err.println("In finally");
        }
    }
}

Should print:

In catch IOException: class java.io.IOException
In finally
Exception in thread "main" java.lang.RuntimeException
        at Catch.main(Catch.java:8)

Technically that could have been a compiler bug, implementation dependent, unspecified behaviour, or something. However, the JLS is pretty well nailed down and the compilers are good enough for this sort of simple thing (generics corner case may be a different matter).

Also note, if you swap around the two catch blocks, it wont compile. The second catch would be completely unreachable.

Note the finally block always runs even if a catch block is executed (other than silly cases, such as infinite loops, attaching through the tools interface and killing the thread, rewriting bytecode, etc.).

It depends on whether you are using JPA or Hibernate.

From the JPA 2.0 spec, the defaults are:

OneToMany: LAZY
ManyToOne: EAGER
ManyToMany: LAZY
OneToOne: EAGER

And in hibernate, all is Lazy

UPDATE:

The latest version of Hibernate aligns with the above JPA defaults.

you need to add it to Foo's prototype:

function Foo(){}
Foo.prototype.bar = function(){}
var x = new Foo()
x.bar()

As others have mentioned the underlying dict is unordered. However there are OrderedDict objects in python. ( They're built in in recent pythons, or you can use this: http://code.activestate.com/recipes/576693/ ).

I believe that newer pythons json implementations correctly handle the built in OrderedDicts, but I'm not sure (and I don't have easy access to test).

Old pythons simplejson implementations dont handle the OrderedDict objects nicely .. and convert them to regular dicts before outputting them.. but you can overcome this by doing the following:

class OrderedJsonEncoder( simplejson.JSONEncoder ):
   def encode(self,o):
      if isinstance(o,OrderedDict.OrderedDict):
         return "{" + ",".join( [ self.encode(k)+":"+self.encode(v) for (k,v) in o.iteritems() ] ) + "}"
      else:
         return simplejson.JSONEncoder.encode(self, o)

now using this we get:

>>> import OrderedDict
>>> unordered={"id":123,"name":"a_name","timezone":"tz"}
>>> ordered = OrderedDict.OrderedDict( [("id",123), ("name","a_name"), ("timezone","tz")] )
>>> e = OrderedJsonEncoder()
>>> print e.encode( unordered )
{"timezone": "tz", "id": 123, "name": "a_name"}
>>> print e.encode( ordered )
{"id":123,"name":"a_name","timezone":"tz"}

Which is pretty much as desired.

Another alternative would be to specialise the encoder to directly use your row class, and then you'd not need any intermediate dict or UnorderedDict.

In the directories are also many binary files. I can't search only certain directories (the directory structure is a big mess). Is there's a better way of grepping only in certain files?

ripgrep

This is one of the quickest tools designed to recursively search your current directory. It is written in Rust, built on top of Rust's regex engine for maximum efficiency. Check the detailed analysis here.

So you can just run:

rg "some_pattern"

It respect your .gitignore and automatically skip hidden files/directories and binary files.

You can still customize include or exclude files and directories using -g/--glob. Globbing rules match .gitignore globs. Check man rg for help.

For more examples, see: How to exclude some files not matching certain extensions with grep?

On macOS, you can install via brew install ripgrep.

df[df['Value']==df['Value'].max()]

This will return the entire row with max value

There are 2 calls that need to set the correct headers. Initially there is a preflight check so you need something like...

app.get('/item', item.list);
app.options('/item', item.preflight);

and then have the following functions...

exports.list = function (req, res) {
Items.allItems(function (err, items) {
    ...
        res.header('Access-Control-Allow-Origin', "*");     // TODO - Make this more secure!!
        res.header('Access-Control-Allow-Methods', 'GET,PUT,POST');
        res.header('Access-Control-Allow-Headers', 'Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept');
        res.send(items);
      }
   );
};

and for the pre-flight checks

exports.preflight = function (req, res) {
Items.allItems(function (err, items) {
        res.header('Access-Control-Allow-Origin', "*");     // TODO - Make this more secure!!
        res.header('Access-Control-Allow-Methods', 'GET,PUT,POST');
        res.header('Access-Control-Allow-Headers', 'Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept');
        res.send(200);
    }
  );
};

You can consolidate the res.header() code into a single function if you want.

Also as stated above, be careful of using res.header('Access-Control-Allow-Origin', "*") this means anyone can access your site!

Swift 3.0 version

Following closure function execute some task after delay on main thread.

func performAfterDelay(delay : Double, onCompletion: @escaping() -> Void){

    DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + delay, execute: {
       onCompletion()
    })
}

Call this function like:

performAfterDelay(delay: 4.0) {
  print("test")
}

This is not to check for null, instead this will be helpful in converting an existing object to an empty object(fresh object). I dont know whether this is relevant or not, but I had such a requirement.

@SuppressWarnings({ "unchecked" })
static void emptyObject(Object obj) 
{
    Class c1 = obj.getClass();
    Field[] fields = c1.getDeclaredFields();

    for(Field field : fields)
    {
        try
        {
            if(field.getType().getCanonicalName() == "boolean")
            {
                field.set(obj, false);
            }
            else if(field.getType().getCanonicalName() == "char")
            {
                field.set(obj, '\u0000');
            }
            else if((field.getType().isPrimitive()))
            {
                field.set(obj, 0);
            }
            else
            {
                field.set(obj, null);
            }
        }
        catch(Exception ex)
        {

        }
    }
}

The accepted answer let keyExists = dict[key] != nil will not work if the Dictionary contains the key but has a value of nil.

If you want to be sure the Dictionary does not contain the key at all use this (tested in Swift 4).

if dict.keys.contains(key) {
  // contains key
} else { 
  // does not contain key
}

NSLocale* currentLocale = [NSLocale currentLocale];
[[NSDate date] descriptionWithLocale:currentLocale];  

or use

NSDateFormatter *dateFormatter=[[NSDateFormatter alloc] init]; 
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
// or @"yyyy-MM-dd hh:mm:ss a" if you prefer the time with AM/PM 
NSLog(@"%@",[dateFormatter stringFromDate:[NSDate date]]);

You can use this method also it will act like that

thadari=[1,2,3,4,5,6]

#Front Two(Left)
print(thadari[:2])
[1,2]

#Last Two(Right)# edited
print(thadari[-2:])
[5,6]

#mid
mid = len(thadari) //2

lefthalf = thadari[:mid]
[1,2,3]
righthalf = thadari[mid:]
[4,5,6]

Hope it will help

Workaround: This is a problem we have observed too, in Windows Server 2012 R2. I haven't found a reason or solution yet. Here is my work around.

During installation while error is shown, go to Services.msc. Find the service which throws the error, then re-enter the password in the service's log-in information. Then, hit "retry" in setup. It works.

The error will not be shown for same user again. But will be shown for a different user.

Pickle uses different protocols to convert your data to a binary stream.

• In python 2 there are 3 different protocols (0, 1, 2) and the default is 0.

• In python 3 there are 5 different protocols (0, 1, 2, 3, 4) and the default is 3.

You must specify in python 3 a protocol lower than 3 in order to be able to load the data in python 2. You can specify the protocol parameter when invoking pickle.dump.

@bhamby is correct. By leaving the microseconds off of your timestamp value, your query would only match on a usagetime of 2012-09-03 08:03:06.000000

If you don't have the complete timestamp value captured from a previous query, you can specify a ranged predicate that will match on any microsecond value for that time:

...WHERE id = 1 AND usagetime BETWEEN '2012-09-03 08:03:06' AND '2012-09-03 08:03:07'

or

...WHERE id = 1 AND usagetime >= '2012-09-03 08:03:06' 
   AND usagetime < '2012-09-03 08:03:07'

There are two things to consider: users can modify forms, and you need to secure against Cross Site Scripting (XSS).

XSS

XSS is when a user enters HTML into their input. For example, what if a user submitted this value?:

" /><script type="text/javascript" src="http://example.com/malice.js"></script><input value="

This would be written into your form like so:

<input type="hidden" name="prova[]" value="" /><script type="text/javascript" src="http://example.com/malice.js"></script><input value=""/>

The best way to protect against this is to use htmlspecialchars() to secure your input. This encodes characters such as < into <. For example:

<input type="hidden" name="prova[]" value="<?php echo htmlspecialchars($array); ?>"/>

You can read more about XSS here: https://www.owasp.org/index.php/XSS

Form Modification

If I were on your site, I could use Chrome's developer tools or Firebug to modify the HTML of your page. Depending on what your form does, this could be used maliciously.

I could, for example, add extra values to your array, or values that don't belong in the array. If this were a file system manager, then I could add files that don't exist or files that contain sensitive information (e.g.: replace myfile.jpg with ../index.php or ../db-connect.php).

In short, you always need to check your inputs later to make sure that they make sense, and only use safe inputs in forms. A File ID (a number) is safe, because you can check to see if the number exists, then extract the filename from a database (this assumes that your database contains validated input). A File Name isn't safe, for the reasons described above. You must either re-validate the filename or else I could change it to anything.

Replace the whitespace characters, and then convert it(using the intval function or by regular typecasting)

intval(str_replace(" ", "", $b))

For a permanent solution I found the following worked:

[Environment]::SetEnvironmentVariable("Path", "$env:Path;C:\Python 3.5")

Update August 2020

As mentioned originally in this answer by SoBeRich, and in my own answer, as of git 2.4.x

git push --atomic origin <branch name> <tag>

(Note: this actually work with HTTPS only with Git 2.24)

Update May 2015

As of git 2.4.1, you can do

git config --global push.followTags true

If set to true enable --follow-tags option by default.
You may override this configuration at time of push by specifying --no-follow-tags.

As noted in this thread by Matt Rogers answering Wes Hurd:

--follow-tags only pushes annotated tags.

git tag -a -m "I'm an annotation" <tagname>

That would be pushed (as opposed to git tag <tagname>, a lightweight tag, which would not be pushed, as I mentioned here)

Update April 2013

Since git 1.8.3 (April 22d, 2013), you no longer have to do 2 commands to push branches, and then to push tags:

The new "--follow-tags" option tells "git push" to push relevant annotated tags when pushing branches out.

You can now try, when pushing new commits:

git push --follow-tags

That won't push all the local tags though, only the one referenced by commits which are pushed with the git push.

Git 2.4.1+ (Q2 2015) will introduce the option push.followTags: see "How to make “git push” include tags within a branch?".

Original answer, September 2010

The nuclear option would be git push --mirror, which will push all refs under refs/.

You can also push just one tag with your current branch commit:

git push origin : v1.0.0 

You can combine the --tags option with a refspec like:

git push origin --tags :

(since --tags means: All refs under refs/tags are pushed, in addition to refspecs explicitly listed on the command line)

You also have this entry "Pushing branches and tags with a single "git push" invocation"

A handy tip was just posted to the Git mailing list by Zoltán Füzesi:

I use .git/config to solve this:

[remote "origin"]
    url = ...
    fetch = +refs/heads/*:refs/remotes/origin/*
    push = +refs/heads/*
    push = +refs/tags/*

With these lines added git push origin will upload all your branches and tags. If you want to upload only some of them, you can enumerate them.

Haven't tried it myself yet, but it looks like it might be useful until some other way of pushing branches and tags at the same time is added to git push.
On the other hand, I don't mind typing:

$ git push && git push --tags

Beware, as commented by Aseem Kishore

push = +refs/heads/* will force-pushes all your branches.

This bit me just now, so FYI.

René Scheibe adds this interesting comment:

The --follow-tags parameter is misleading as only tags under .git/refs/tags are considered.
If git gc is run, tags are moved from .git/refs/tags to .git/packed-refs. Afterwards git push --follow-tags ... does not work as expected anymore.

Try nslookup google.com to determine if there's a DNS issue. 192.168.1.254 is your local network address and it looks like your system is using it as a DNS server. Is this your gateway/modem router as well? What happens when you try ping google.com. Can you browse to it on a Internet web browser?

If memory serves correct, the reg add command will NOT create the entire directory path if it does not exist. Meaning that if any of the parent registry keys do not exist then they must be created manually one by one. It is really annoying, I know! Example:

@echo off
reg add "HKCU\Software\Policies"
reg add "HKCU\Software\Policies\Microsoft"
reg add "HKCU\Software\Policies\Microsoft\Internet Explorer"
reg add "HKCU\Software\Policies\Microsoft\Internet Explorer\Control Panel"
reg add "HKCU\Software\Policies\Microsoft\Internet Explorer\Control Panel" /v HomePage /t REG_DWORD /d 1 /f
pause

I've found that using:

<img src="file://null">

will not make a request and validates correctly.

The browsers will simply block the access to the local file system.

But there might be an error displayed in console log in Chrome for example:

Not allowed to load local resource: file://null/

It is because of this line:

printf ("Hi %s,</br />", $name);

You should not print/echo anything before sending the headers.

A simple return statement will 'stop' or return the function; in precise terms, it 'returns' function execution to the point at which the function was called - the function is terminated without further action.

That means you could have a number of places throughout your function where it might return. Like this:

def player():
    # do something here

I was using above command but it was not working. This command worked for me:

python -m pip uninstall pip setuptools

As of Java 8, you can use a lambda to capture parameters that are effectively final. For example:

final String param1 = "First param";
final int param2 = 2;
new Thread(() -> {
    // Do whatever you want here: param1 and param2 are in-scope!
    System.out.println(param1);
    System.out.println(param2);
}).start();

Topic Solution

The correct command to answer the posted question could be any of the following (assuming branch topic is already checked out):

git rebase --onto B master
git rebase --onto master~1 master
git rebase --onto B A
git rebase --onto B C
git rebase --onto B

If topic is not checked out, you simply append topic to the command (except the last one) like so:

git rebase --onto B master topic

Alternatively, check out the branch first with:

git checkout topic

Rebase Any String of Commits to a Target Commit

The basic form of the command we need, cribbed from the documentation, is:

git rebase --onto <Target> [<Upstream> [<Branch>]]

<Branch> is optional and all it does is checks out the branch specified before executing the rest of the command. If you've already checked out the branch you want to rebase, then you don't need this. Note that you must have specified <Upstream> in order to specify <Branch> or git will think you are specifying <Upstream>.

<Target> is the commit we will attach our string of commits to. When providing a branch name, you are simply specifying the head commit of that branch. <Target> can be any commit that won't be contained in the string of commits being moved. For example:

A --- B --- C --- D         master
      \
       \-- X --- Y --- Z    feature

To move the entire feature branch, you can not select X, Y, Z, or feature as the <Target> since those all are commits inside the group being moved.

<Upstream> is special because it can mean two different things. If it is a commit that is an ancestor of the checked out branch, then it serves as the cut point. In the example I provided, this would be anything that isn't C, D, or master. All commits after <Upstream> until the head of the checked out branch are the ones that will be moved.

However, if <Upstream> is not an ancestor, then git backs up the chain from the specified commit until if finds a common ancestor with the checked out branch (and aborts if it can't find one). In our case, an <Upstream> of B, C, D, or master will all result in commit B serving as the cut point. <Upstream> is itself an optional command and if it is not specified, then git looks at the parent of the checked out branch which is the equivalent of entering master.

Now that git has selected the commits it will cut and move, it applies them in order to <Target>, skipping any that are already applied to target.

Interesting Examples and Results

Using this starting point:

A --- B --- C --- D --- E         master
            \
             \-- X --- Y --- Z    feature

• git rebase --onto D A feature
  Will apply commits B, C, X, Y, Z to commit D and end up skipping B and C because they already have been applied.

• git rebase --onto C X feature
  Will apply commits Y and Z to commit C, effectively deleting commit X

The better answers to this only work for specific lengths of lists that are provided.

Here's a version that works for any lengths of input. It also makes the algorithm clear in terms of the mathematical concepts of combination and permutation.

from itertools import combinations, permutations
list1 = ['1', '2']
list2 = ['A', 'B', 'C']

num_elements = min(len(list1), len(list2))
list1_combs = list(combinations(list1, num_elements))
list2_perms = list(permutations(list2, num_elements))
result = [
  tuple(zip(perm, comb))
  for comb in list1_combs
  for perm in list2_perms
]

for idx, ((l11, l12), (l21, l22)) in enumerate(result):
  print(f'{idx}: {l11}{l12} {l21}{l22}')

This outputs:

0: A1 B2
1: A1 C2
2: B1 A2
3: B1 C2
4: C1 A2
5: C1 B2

here it's the solution for if there have any assigned values inside the string.xml file.

 <string name="styled_welcome_message"><![CDATA[We are <b> %1$s </b>  glad to see you.]]></string>

set in to TextView:

textView?.setText(HtmlCompat.fromHtml(getString(R.string.styled_welcome_message, "sample"), HtmlCompat.FROM_HTML_MODE_LEGACY), TextView.BufferType.SPANNABLE)

Return the task_id (which is given from .delay()) and ask the celery instance afterwards about the state:

x = method.delay(1,2)
print x.task_id

When asking, get a new AsyncResult using this task_id:

from celery.result import AsyncResult
res = AsyncResult("your-task-id")
res.ready()

Although, the question is fairly old, I'm adding info not present in other answers.

The OP is using stop() to stop the current animation as soon as the event completes. However, using the right mix of parameters with the function should help. eg. stop(true,true) or stop(true,false) as this affects the queued animations well.

The following link illustrates a demo that shows the different parameters available with stop() and how they differ from finish().

http://api.jquery.com/finish/

Although the OP had no issues using JqueryUI, this is for other users who may come across similar scenarios but cannot use JqueryUI/need to support IE7 and 8 too.

In my case, it's because the files already exist in the repository and I'm trying to ignore it.

These are the things I did to fix the issue:

• Copy the files to a temporary folder
• Remove them from my project folder.
• Commit the changes which remove those files from the repository
• Re-added those files to my project folder

By then, any changes I made on those files were ignored.

I think you can't ignore files that already exist on the repository.

'joins' just used to join tables and when you called associations on joins then it will again fire query (it mean many query will fire)

lets suppose you have tow model, User and Organisation
User has_many organisations
suppose you have 10 organisation for a user 
@records= User.joins(:organisations).where("organisations.user_id = 1")
QUERY will be 
 select * from users INNER JOIN organisations ON organisations.user_id = users.id where organisations.user_id = 1

it will return all records of organisation related to user
and @records.map{|u|u.organisation.name}
it run QUERY like 
select * from organisations where organisations.id = x then time(hwo many organisation you have)

total number of SQL is 11 in this case

But with 'includes' will eager load the included associations and add them in memory(load all associations on first load) and not fire query again

when you get records with includes like @records= User.includes(:organisations).where("organisations.user_id = 1") then query will be

select * from users INNER JOIN organisations ON organisations.user_id = users.id where organisations.user_id = 1
and 


 select * from organisations where organisations.id IN(IDS of organisation(1, to 10)) if 10 organisation
and when you run this 

@records.map{|u|u.organisation.name} no query will fire

To run the python file on mac.

1. Open the preferences in atom ide. To open the preferences press 'command + . ' ( ? + , )

2. Click on the install in the preferences to install packages.

3. Search for package "script" and click on install

4. Now open the python file(with .py extension ) you want to run and press 'control + r ' (^ + r)

Line width in ggplot2 can be changed with argument size= in geom_line().

#sample data
df<-data.frame(x=rnorm(100),y=rnorm(100))
ggplot(df,aes(x=x,y=y))+geom_line(size=2)

I was facing the same problem for a long time but I solved it by adjusting the settings in gradle.

Step 1:In Module app add dependency in BuildScript

buildscript {
 dependencies {
         classpath 'com.android.tools.build:gradle:2.0.0-alpha9'
}
}

Step 2: Add dexOption and give the following heapSize

  dexOptions {
    incremental = true;
    preDexLibraries = false
    javaMaxHeapSize "4g"
}

Step 3: Add productFlavors

    productFlavors {
    dev {
        minSdkVersion 23
        applicationId = "com.Reading.home"
    }
    prod {
        minSdkVersion 15
        applicationId = "com.Reading.home" // you don't need it, but can be useful

    }
}

This should reduce your build time.

Update

I've written a cross-browser range and selection library called Rangy that incorporates an improved version of the code I posted below. You can use the selection save and restore module for this particular question, although I'd be tempted to use something like @Nico Burns's answer if you're not doing anything else with selections in your project and don't need the bulk of a library.

Previous answer

You can use IERange (http://code.google.com/p/ierange/) to convert IE's TextRange into something like a DOM Range and use it in conjunction with something like eyelidlessness's starting point. Personally I would only use the algorithms from IERange that do the Range <-> TextRange conversions rather than use the whole thing. And IE's selection object doesn't have the focusNode and anchorNode properties but you should be able to just use the Range/TextRange obtained from the selection instead.

I will write this up fully at some point soon.

modern shells already support arrays( and even associative arrays). So please do use them, and use less of eval.

var1="this is the real value"
array=("$var1")
# or array[0]="$var1"

then when you want to call it , echo ${array[0]}

If you have iAds in your binary you will not be able to run it on anything before iOS 4.0 and it will be rejected if you try and submit a binary like this.

You can still run the simulator from 3.2 onwards after upgrading.

In the iPhone Simulator try selecting Hardware -> Version -> 3.2

Yes, but it's clunky as hell, e.g.

<c:choose>
  <c:when test="${condition1}">
    ...
  </c:when>
  <c:when test="${condition2}">
    ...
  </c:when>
  <c:otherwise>
    ...
  </c:otherwise>
</c:choose>

java.io.IOException in Netty means your game server tries to send data to a client, but that client has closed connection to your server.

And that exception is not the only one! There're several others. See BadClientSilencer in Xitrum. I had to add that to prevent those errors from messing my log file.

for what it's worth I'm using node.js 0.6.7 on OSX and I couldn't get 'Authorization':auth to work with our proxy, it needed to be set to 'Proxy-Authorization':auth my test code is:

var http = require("http");
var auth = 'Basic ' + new Buffer("username:password").toString('base64');
var options = {
    host: 'proxyserver',
    port: 80,
    method:"GET",
    path: 'http://www.google.com',
    headers:{
        "Proxy-Authorization": auth,
        Host: "www.google.com"
    } 
};
http.get(options, function(res) {
    console.log(res);
    res.pipe(process.stdout);
});

I would say it's better to use var in most situations.

Local variables are always faster than the variables in global scope.

If you do not use var to declare a variable, the variable will be in global scope.

For more information, you can search "scope chain JavaScript" in Google.

Download the file and from the same directory run docker build -t nodebb .

This will give you an image on your local machine that's named nodebb that you can launch an container from with docker run -d nodebb (you can change nodebb to your own name).

So actually, my comment that you should do a console.log(el.nativeElement) should have pointed you in the right direction, but I didn't expect the output to be just a string representing the DOM Element.

What you have to do to inspect it in the way it helps you with your problem, is to do a console.log(el) in your example, then you'll have access to the nativeElement object and will see a property called innerHTML.

Which will lead to the answer to your original question:

let myCurrentContent:string = el.nativeElement.innerHTML; // get the content of your element
el.nativeElement.innerHTML = 'my new content'; // set content of your element

Update for better approach:

Since it's the accepted answer and web workers are getting more important day to day (and it's considered best practice anyway) I want to add this suggestion by Mark Rajcok here.

The best way to manipulate DOM Elements programmatically is using the Renderer:

constructor(private _elemRef: ElementRef, private _renderer: Renderer) { 
    this._renderer.setElementProperty(this._elemRef.nativeElement, 'innerHTML', 'my new content');
}

Edit

Since Renderer is deprecated now, use Renderer2 instead with setProperty

Update:

This question with its answer explained the console.log behavior.

Which means that console.dir(el.nativeElement) would be the more direct way of accessing the DOM Element as an "inspectable" Object in your console for this situation.

Hope this helped.

try this,

string FileNameAndExtension =  "bilah bilah.pdf";
string FileName = FileNameAndExtension.Split('.')[0];
