It's because you haven't declared outchar before you use it. That means that the compiler will assume it's a function returning an int and taking an undefined number of undefined arguments.

You need to add a prototype pf the function before you use it:

void outchar(char);  /* Prototype (declaration) of a function to be called */  int main(void) {     ... }  void outchar(char ch) {     ... } 

Note the declaration of the main function differs from your code as well. It's actually a part of the official C specification, it must return an int and must take either a void argument or an int and a char** argument.

I was playing around with this and tried all solutions, eventually the solution I went with was a suggestion from Google Chrome's Inspector. If you add this to your CSS it worked for me:

video{
   object-fit: inherit;
}

java.lang.NoSuchMethodError: javax.servlet.ServletContext.getContextPath()Ljava/lang/String;

That method was added in Servlet 2.5.

So this problem can have at least 3 causes:

1. The servlet container does not support Servlet 2.5.
2. The web.xml is not declared conform Servlet 2.5 or newer.
3. The webapp's runtime classpath is littered with servlet container specific JAR files of a different servlet container make/version which does not support Servlet 2.5.

To solve it,

1. Make sure that your servlet container supports at least Servlet 2.5. That are at least Tomcat 6, Glassfish 2, JBoss AS 4.1, etcetera. Tomcat 5.5 for example supports at highest Servlet 2.4. If you can't upgrade Tomcat, then you'd need to downgrade Spring to a Servlet 2.4 compatible version.
2. Make sure that the root declaration of web.xml complies Servlet 2.5 (or newer, at least the highest whatever your target runtime supports). For an example, see also somewhere halfway our servlets wiki page.
3. Make sure that you don't have any servlet container specific libraries like servlet-api.jar or j2ee.jar in /WEB-INF/lib or even worse, the JRE/lib or JRE/lib/ext. They do not belong there. This is a pretty common beginner's mistake in an attempt to circumvent compilation errors in an IDE, see also How do I import the javax.servlet API in my Eclipse project?.

In the most languages, break does only cancel loops like for, while etc.

For Docker 1.8, I use:

$ docker inspect -f "{{ .Config.Volumes }}" 957d2dd1d4e8
map[/xmount/dvol.01:{}]

Edit your .bowerrc file ( should be next to your bower.json file ) and add the wanted proxy configuration

"proxy":"http://<host>:<port>",
"https-proxy":"http://<host>:<port>"

Import import android.net.Uri;

Intent openURL = new Intent(android.content.Intent.ACTION_VIEW);
openURL.setData(Uri.parse("http://www.example.com"));
startActivity(openURL);

or it can be done using,

TextView textView = (TextView)findViewById(R.id.yourID);

textView.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
        Intent intent = new Intent();
        intent.setAction(Intent.ACTION_VIEW);
        intent.addCategory(Intent.CATEGORY_BROWSABLE);
        intent.setData(Uri.parse("http://www.typeyourURL.com"));
        startActivity(intent);
    } });

It depends which one to chose is based on the requirement

Handler is mostly used to switch from other thread to main thread, Handler is attached to a looper on which it post its runnable task in queue. So If you are already in other thread and switch to main thread then you need handle instead of async task or other thread

If Handler created in other than main thread which is not a looper is will not give error as handle is created the thread, that thread need to be made a lopper

AsyncTask is used to execute code for few seconds which run on background thread and gives its result to main thread ** *AsyncTask Limitations 1. Async Task is not attached to life cycle of activity and it keeps run even if its activity destroyed whereas loader doesn't have this limitation 2. All Async Tasks share the same background thread for execution which also impact the app performance

Thread is used in app for background work also but it doesn't have any call back on main thread. If requirement suits some threads instead of one thread and which need to give task many times then thread pool executor is better option.Eg Requirement of Image loading from multiple url like glide.

You can try this one as well;

tup = (1,2,3)
print("this is a tuple {something}".format(something=tup))

You can't use %something with (tup) just because of packing and unpacking concept with tuple.

invalid new-expression of abstract class type 'box'

There is nothing unclear about the error message. Your class box has at least one member that is not implemented, which means it is abstract. You cannot instantiate an abstract class.

If this is a bug, fix your box class by implementing the missing member(s).

If it's by design, derive from box, implement the missing member(s) and use the derived class.

It depends on your IDE or compiler.

Others will be similar but vary.

I had this error for my XXX element and it was because my XSD was wrongly formatted according to javax.xml.bind v2.2.11 . I think it's using an older XSD format but I didn't bother to confirm.

My initial wrong XSD was alike the following:

<xs:element name="Document" type="Document"/>
...
<xs:complexType name="Document">
    <xs:sequence>
        <xs:element name="XXX" type="XXX_TYPE"/>
    </xs:sequence>
</xs:complexType>

The good XSD format for my migration to succeed was the following:

<xs:element name="Document">
    <xs:complexType>
        <xs:sequence>
            <xs:element ref="XXX"/>
        </xs:sequence>
    </xs:complexType>        
</xs:element>
...
<xs:element name="XXX" type="XXX_TYPE"/>

And so on for every similar XSD nodes.

You can convert your number to string and use list slicing like this:

int(str(number)[:2])

Output:

>>> number = 1520
>>> int(str(number)[:2])
15

This will help you to understand the difference between nil, NIL and null.

The below link may help you in some way:

http://nshipster.com/nil/

nil -> literal null value for Objective-C objects.

Nil -> literal null value for Objective-C classes.

NULL -> literal null value for C pointers.

NSNULL -> singleton object used to represent null.

Methods should be like this:

[Route("api/[controller]")]
public class PersonsController : Controller
{
    [HttpGet("{id}")]
    public Person Get(int id)

    [HttpGet]
    public Person[] Get([FromQuery] string firstName, [FromQuery] string lastName, [FromQuery] string address)
}

Take note that second method returns an array of objects and controller name is in plurar (Persons not Person).

So if you want to get resource by id it will be:

api/persons/1

if you want to take objects by some search criteria like first name and etc, you can do search like this:

api/persons?firstName=Name&...

And moving forward if you want to take that person orders (for example), it should be like this:

api/persons/1/orders?skip=0&take=20

And method in the same controller:

    [HttpGet("{personId}/orders")]
    public Orders[] Get(int personId, int skip, int take, etc..)

Semantic Difference

According to HTML 5.2:

When specified on an element, [the hidden attribute] indicates that the element is not yet, or is no longer, directly relevant to the page’s current state, or that it is being used to declare content to be reused by other parts of the page as opposed to being directly accessed by the user.

Examples include a tab list where some panels are not exposed, or a log-in screen that goes away after a user logs in. I like to call these things “temporally relevant” i.e. they are relevant based on timing.

On the other hand, ARIA 1.1 says:

[The aria-hidden state] indicates whether an element is exposed to the accessibility API.

In other words, elements with aria-hidden="true" are removed from the accessibility tree, which most assistive technology honors, and elements with aria-hidden="false" will definitely be exposed to the tree. Elements without the aria-hidden attribute are in the "undefined (default)" state, which means user agents should expose it to the tree based on its rendering. E.g. a user agent may decide to remove it if its text color matches its background color.

Now let’s compare semantics. It’s appropriate to use hidden, but not aria-hidden, for an element that is not yet “temporally relevant”, but that might become relevant in the future (in which case you would use dynamic scripts to remove the hidden attribute). Conversely, it’s appropriate to use aria-hidden, but not hidden, on an element that is always relevant, but with which you don’t want to clutter the accessibility API; such elements might include “visual flair”, like icons and/or imagery that are not essential for the user to consume.

Effective Difference

The semantics have predictable effects in browsers/user agents. The reason I make a distinction is that user agent behavior is recommended, but not required by the specifications.

The hidden attribute should hide an element from all presentations, including printers and screen readers (assuming these devices honor the HTML specs). If you want to remove an element from the accessibility tree as well as visual media, hidden would do the trick. However, do not use hidden just because you want this effect. Ask yourself if hidden is semantically correct first (see above). If hidden is not semantically correct, but you still want to visually hide the element, you can use other techniques such as CSS.

Elements with aria-hidden="true" are not exposed to the accessibility tree, so for example, screen readers won’t announce them. This technique should be used carefully, as it will provide different experiences to different users: accessible user agents won’t announce/render them, but they are still rendered on visual agents. This can be a good thing when done correctly, but it has the potential to be abused.

Syntactic Difference

Lastly, there is a difference in syntax between the two attributes.

hidden is a boolean attribute, meaning if the attribute is present it is true—regardless of whatever value it might have—and if the attribute is absent it is false. For the true case, the best practice is to either use no value at all (<div hidden>...</div>), or the empty string value (<div hidden="">...</div>). I would not recommend hidden="true" because someone reading/updating your code might infer that hidden="false" would have the opposite effect, which is simply incorrect.

aria-hidden, by contrast, is an enumerated attribute, allowing one of a finite list of values. If the aria-hidden attribute is present, its value must be either "true" or "false". If you want the "undefined (default)" state, remove the attribute altogether.

There are several ways:

Instantiating the array:

var arr;

arr = new Array(); // empty array

// ---

arr = [];          // empty array

// ---

arr = new Array(3);
alert(arr.length);  // 3
alert(arr[0]); // undefined

// ---

arr = [3];
alert(arr.length);  // 1
alert(arr[0]); // 3

Pushing to the array:

arr = [3];     // arr == [3]
arr[1] = 4;    // arr == [3, 4]
arr[2] = 5;    // arr == [3, 4, 5]
arr[4] = 7;    // arr == [3, 4, 5, undefined, 7]

// ---

arr = [3];
arr.push(4);        // arr == [3, 4]
arr.push(5);        // arr == [3, 4, 5]
arr.push(6, 7, 8);  // arr == [3, 4, 5, 6, 7, 8]

Using .push() is the better way to add to an array, since you don't need to know how many items are already there, and you can add many items in one function call.

In addition to what is mentioned above, do not forget while creating sql table to make the AUTO INCREMENT as in this example

CREATE TABLE MY_SQL_TABLE (

  USER_ID INTEGER NOT NULL AUTO_INCREMENT PRIMARY KEY,
  FNAME VARCHAR(50) NOT NULL,
  LNAME VARCHAR(20) NOT NULL,
  EMAIL VARCHAR(50) NOT NULL
);

In my case, I was using RxSwift for performing search.

I had extensively kept using a shared instance of a particular class inside the onNext method, which probably made it inaccessible (Mutex).

Make sure that such instances are handled carefully only when absolutely necessary.

In my case, I made use of a couple of variables beforehand to safely (and sequentially) store the return values of the shared instance's methods, and reused them inside onNext block.

I had a similar issue and it turned out that i had to add an extra entry in cmake to include the files.

Since i was also using the zmq library I had to add this to the included libraries as well.

In Delphi (Pascal):

function GetExcelColumnName(columnNumber: integer): string;
var
  dividend, modulo: integer;
begin
  Result := '';
  dividend := columnNumber;
  while dividend > 0 do begin
    modulo := (dividend - 1) mod 26;
    Result := Chr(65 + modulo) + Result;
    dividend := (dividend - modulo) div 26;
  end;
end;

when your page first loads the PHP code first run and set the complete layout of your webpage. after the page layout, it set the JavaScript load up. now JavaScript directly interacts with DOM and can manipulate the layout but PHP can't it needs to refresh the page. There is only way is to refresh your page to and pass the parameters in the page URL so that you can get the data via PHP. So we use AJAX to interact Javascript with PHP without page reload. AJAX can also be used as an API. one more thing if you have already declared the variable in PHP. before the page load then you can use it with your Javascript example.

<script>
var username = "<?php echo $myname;?>";
alert(username);
</script>

the above code is correct and it will work. but the code below is totally wrong and it will never work.

<script>
    var username = "syed ali";
    var <?php $myname;?> = username;
    alert(myname);
    </script>

• Pass value from JavaScript to PHP via AJAX

  it is the most secure way to do it. because HTML content can be edited via developer tools and the user can manipulate the data. so it is better to use AJAX if you want security over that variable.if you are a newbie to AJAX please learn AJAX it is very simple.

The best and most secure way to pass JavaScript variable into PHP is via AJAX

simple AJAX example

var mydata = 55;
var myname = "syed ali";
var userdata = {'id':mydata,'name':myname};
    $.ajax({
            type: "POST",
            url: "YOUR PHP URL HERE",
            data:userdata, 
            success: function(data){
                console.log(data);
            }
            });

• PASS value from javascript to php via hidden fields.

otherwise, you can create hidden HTML input inside your form. like

<input type="hidden" id="mydata">

then via jQuery or javaScript pass the value to the hidden field. like

<script>
var myvalue = 55;
$("#mydata").val(myvalue);
</script>

Now when you submit the form you can get the value in PHP.

Maximum time between connection request and a timeout error. When the client tries to make a connection, if the timeout wait limit is reached, it will stop trying and raise an error.

There are couple of ways you can search as "LIKE" operator of SQL in C#. If you just want to know whether the pattern exists in the string variable, you can use

string value = "samplevalue";
        value.Contains("eva"); // like '%eva%'
         value.StartsWith("eva");  // like 'eva%'
        value.EndsWith("eva"); // like '%eva'

if you want to search the pattern from a list of string, you should use LINQ to Object Features.

            List<string> valuee = new List<string> { "samplevalue1", "samplevalue2", "samplevalue3" };
        List<string> contains = (List<string>) (from val in valuee
                                        where val.Contains("pattern")
                                        select val); // like '%pattern%'

        List<string> starts = (List<string>) (from val in valuee
                                      where val.StartsWith("pattern")
                                      select val);// like 'pattern%'

        List<string> ends = (List<string>) (from val in valuee                          
                                    where val.EndsWith ("pattern")
                                    select val);// like '%pattern'

A very simple way to do this is by the following:

onClick={this.fun.bind(this)}

and for the function:

fun() {
  this.props.history.push("/Home");
}

finlay you need to import withRouter:

import { withRouter } from 'react-router-dom';

and export it as:

export default withRouter (comp_name);

For someone who would like to use urlsafe_b64encode and urlsafe_b64decode, here are the version that're working for me (after spending some time with the unicode issue)

BS = 16
key = hashlib.md5(settings.SECRET_KEY).hexdigest()[:BS]
pad = lambda s: s + (BS - len(s) % BS) * chr(BS - len(s) % BS)
unpad = lambda s : s[:-ord(s[len(s)-1:])]

class AESCipher:
    def __init__(self, key):
        self.key = key

    def encrypt(self, raw):
        raw = pad(raw)
        iv = Random.new().read(AES.block_size)
        cipher = AES.new(self.key, AES.MODE_CBC, iv)
        return base64.urlsafe_b64encode(iv + cipher.encrypt(raw)) 

    def decrypt(self, enc):
        enc = base64.urlsafe_b64decode(enc.encode('utf-8'))
        iv = enc[:BS]
        cipher = AES.new(self.key, AES.MODE_CBC, iv)
        return unpad(cipher.decrypt(enc[BS:]))

I wanted to store a post in my application, so I created a controller of posts (PostsController) with the resources included:

php artisan make:controller PostsController --resource

The controller was created with all the methods needed to do a CRUD app, then I added the following code to the web.php in the routes folder :

Route::resource('posts', 'PostsController');

I solved the form action problem by doing this:

1. I checked my routing list by doing php artisan route:list
2. I searched for the route name of the store method in the result table in the terminal and I found it under the name of posts.store
3. I added this to the action attribute of my form: action="{{route('posts.store')}}" instead of action="??what to write here??"

You can take the ToArray() call off the end. Is there a reason you need it to be an array after the call to Concat?

Calling Concat creates an iterator over both arrays. It does not create a new array so you have not used more memory for a new array. When you call ToArray you actually do create a new array and take up the memory for the new array.

So if you just need to easily iterate over both then just call Concat.

"How can I directly (without saving the file on 2nd server) download the file from 1st server to client's machine?"

Just use the Client API and get the InputStream from the response

Client client = ClientBuilder.newClient();
String url = "...";
final InputStream responseStream = client.target(url).request().get(InputStream.class);

There are two flavors to get the InputStream. You can also use

Response response = client.target(url).request().get();
InputStream is = (InputStream)response.getEntity();

Which one is the more efficient? I'm not sure, but the returned InputStreams are different classes, so you may want to look into that if you care to.

From 2nd server I can get a ByteArrayOutputStream to get the file from 1st server, can I pass this stream further to the client using the REST service?

So most of the answers you'll see in the link provided by @GradyGCooper seem to favor the use of StreamingOutput. An example implementation might be something like

final InputStream responseStream = client.target(url).request().get(InputStream.class);
System.out.println(responseStream.getClass());
StreamingOutput output = new StreamingOutput() {
    @Override
    public void write(OutputStream out) throws IOException, WebApplicationException {  
        int length;
        byte[] buffer = new byte[1024];
        while((length = responseStream.read(buffer)) != -1) {
            out.write(buffer, 0, length);
        }
        out.flush();
        responseStream.close();
    }   
};
return Response.ok(output).header(
        "Content-Disposition", "attachment, filename=\"...\"").build();

But if we look at the source code for StreamingOutputProvider, you'll see in the writeTo, that it simply writes the data from one stream to another. So with our implementation above, we have to write twice.

How can we get only one write? Simple return the InputStream as the Response

final InputStream responseStream = client.target(url).request().get(InputStream.class);
return Response.ok(responseStream).header(
        "Content-Disposition", "attachment, filename=\"...\"").build();

If we look at the source code for InputStreamProvider, it simply delegates to ReadWriter.writeTo(in, out), which simply does what we did above in the StreamingOutput implementation

 public static void writeTo(InputStream in, OutputStream out) throws IOException {
    int read;
    final byte[] data = new byte[BUFFER_SIZE];
    while ((read = in.read(data)) != -1) {
        out.write(data, 0, read);
    }
}

Asides:

• Client objects are expensive resources. You may want to reuse the same Client for request. You can extract a WebTarget from the client for each request.

  WebTarget target = client.target(url);
  InputStream is = target.request().get(InputStream.class);
  

  I think the WebTarget can even be shared. I can't find anything in the Jersey 2.x documentation (only because it is a larger document, and I'm too lazy to scan through it right now :-), but in the Jersey 1.x documentation, it says the Client and WebResource (which is equivalent to WebTarget in 2.x) can be shared between threads. So I'm guessing Jersey 2.x would be the same. but you may want to confirm for yourself.

• You don't have to make use of the Client API. A download can be easily achieved with the java.net package APIs. But since you're already using Jersey, it doesn't hurt to use its APIs

• The above is assuming Jersey 2.x. For Jersey 1.x, a simple Google search should get you a bunch of hits for working with the API (or the documentation I linked to above)

UPDATE

I'm such a dufus. While the OP and I are contemplating ways to turn a ByteArrayOutputStream to an InputStream, I missed the simplest solution, which is simply to write a MessageBodyWriter for the ByteArrayOutputStream

import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.lang.annotation.Annotation;
import java.lang.reflect.Type;
import javax.ws.rs.WebApplicationException;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.MultivaluedMap;
import javax.ws.rs.ext.MessageBodyWriter;
import javax.ws.rs.ext.Provider;

@Provider
public class OutputStreamWriter implements MessageBodyWriter<ByteArrayOutputStream> {

    @Override
    public boolean isWriteable(Class<?> type, Type genericType,
            Annotation[] annotations, MediaType mediaType) {
        return ByteArrayOutputStream.class == type;
    }

    @Override
    public long getSize(ByteArrayOutputStream t, Class<?> type, Type genericType,
            Annotation[] annotations, MediaType mediaType) {
        return -1;
    }

    @Override
    public void writeTo(ByteArrayOutputStream t, Class<?> type, Type genericType,
            Annotation[] annotations, MediaType mediaType,
            MultivaluedMap<String, Object> httpHeaders, OutputStream entityStream)
            throws IOException, WebApplicationException {
        t.writeTo(entityStream);
    }
}

Then we can simply return the ByteArrayOutputStream in the response

return Response.ok(baos).build();

D'OH!

UPDATE 2

Here are the tests I used (

Resource class

@Path("test")
public class TestResource {

    final String path = "some_150_mb_file";

    @GET
    @Produces(MediaType.APPLICATION_OCTET_STREAM)
    public Response doTest() throws Exception {
        InputStream is = new FileInputStream(path);
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        int len;
        byte[] buffer = new byte[4096];
        while ((len = is.read(buffer, 0, buffer.length)) != -1) {
            baos.write(buffer, 0, len);
        }
        System.out.println("Server size: " + baos.size());
        return Response.ok(baos).build();
    }
}

Client test

public class Main {
    public static void main(String[] args) throws Exception {
        Client client = ClientBuilder.newClient();
        String url = "http://localhost:8080/api/test";
        Response response = client.target(url).request().get();
        String location = "some_location";
        FileOutputStream out = new FileOutputStream(location);
        InputStream is = (InputStream)response.getEntity();
        int len = 0;
        byte[] buffer = new byte[4096];
        while((len = is.read(buffer)) != -1) {
            out.write(buffer, 0, len);
        }
        out.flush();
        out.close();
        is.close();
    }
}

UPDATE 3

So the final solution for this particular use case was for the OP to simply pass the OutputStream from the StreamingOutput's write method. Seems the third-party API, required a OutputStream as an argument.

StreamingOutput output = new StreamingOutput() {
    @Override
    public void write(OutputStream out) {
        thirdPartyApi.downloadFile(.., .., .., out);
    }
}
return Response.ok(output).build();

Not quite sure, but seems the reading/writing within the resource method, using ByteArrayOutputStream`, realized something into memory.

The point of the downloadFile method accepting an OutputStream is so that it can write the result directly to the OutputStream provided. For instance a FileOutputStream, if you wrote it to file, while the download is coming in, it would get directly streamed to the file.

It's not meant for us to keep a reference to the OutputStream, as you were trying to do with the baos, which is where the memory realization comes in.

So with the way that works, we are writing directly to the response stream provided for us. The method write doesn't actually get called until the writeTo method (in the MessageBodyWriter), where the OutputStream is passed to it.

You can get a better picture looking at the MessageBodyWriter I wrote. Basically in the writeTo method, replace the ByteArrayOutputStream with StreamingOutput, then inside the method, call streamingOutput.write(entityStream). You can see the link I provided in the earlier part of the answer, where I link to the StreamingOutputProvider. This is exactly what happens

You might consider Joda Time or Java 8, which has a type called LocalTime specifically for a time of day without a date component.

Example code in Joda-Time 2.7/Java 8.

LocalTime t = LocalTime.parse( "17:40" ) ;

See:- ConnectionStrings content on this subject. There is no default command timeout property.

1. Use a semi-colon ; to separate command
2. Replace double backslash \\ on any backslashes \.
3. Use "' for passing safe address to switch command like "'PATH'".

This ps1 command install locale pfx certificate.

powershell -Command "$pfxPassword = ConvertTo-SecureString -String "12345678" -Force -AsPlainText ; Import-PfxCertificate -FilePath "'C:\\Program Files\\VpnManagement\\resources\\assets\\cert\\localhost.pfx'" Cert:\\LocalMachine\\My -Password $pfxPassword ; Import-PfxCertificate -FilePath "'C:\\Program Files\\VpnManagement\\resources\\assets\\cert\\localhost.pfx'" Cert:\\LocalMachine\\Root -Password $pfxPassword"

The plyr package can be used for this. With the ddply() function you can split a data frame on one or more columns and apply a function and return a data frame, then with the summarize() function you can use the columns of the splitted data frame as variables to make the new data frame/;

dat <- read.table(textConnection('Group Score Info
1     1     1    a
2     1     2    b
3     1     3    c
4     2     4    d
5     2     3    e
6     2     1    f'))

library("plyr")

ddply(dat,.(Group),summarize,
    Max = max(Score),
    Info = Info[which.max(Score)])
  Group Max Info
1     1   3    c
2     2   4    d

Had a similar problem. My solution was to give the inner table a fixed height of 1px and set the height of the td in the inner table to 100%. Against all odds, it works fine, tested in IE, Chrome and FF!

Try this:

I use this everywhere where there is a $_POST request.

$username=isset($_POST['username']) ? $_POST['username'] : "";

This is just a short hand boolean, if isset it will set it to $_POST['username'], if not then it will set it to an empty string.

Usage example:

if($username===""){ echo "Field is blank" } else { echo "Success" };

You need to add this entry to application.properties to bypass Springboot Default Security

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.security.SecurityAutoConfiguration

Then there won't be any authentication box. otrws, credentials are:- user and 99b962fa-1848-4201-ae67-580bdeae87e9 (password randomly generated)

Note: my springBootVersion = '1.5.14.RELEASE'

You can create a simple rule by doing something like this:

jQuery.validator.addMethod("greaterThanZero", function(value, element) {
    return this.optional(element) || (parseFloat(value) > 0);
}, "* Amount must be greater than zero");

And then applying this like so:

$('validatorElement').validate({
    rules : {
        amount : { greaterThanZero : true }
    }
});

Just change the contents of the 'addMethod' to validate your checkboxes.

You need a list as a dictionary value. This code will do the trick.

from collections import defaultdict
mydict = defaultdict(list)
for k, v in zip(df.id.values,df.value.values):
    mydict[k].append(v)

You wont be able to access a local resource from your aspx page (web server). Have you tried a relative path from your aspx page to your css file like so...

<link rel="stylesheet" media="all" href="/CSS/Style.css" type="text/css" />

The above assumes that you have a folder called CSS in the root of your website like this:

http://www.website.com/CSS/Style.css

I know this is a very old question, but I googled my way here and found the answer provided not 100% satisfying, because as gcl1 mentioned - this way the footer is not really a footer to the screen - it's just an "add-on" to the list.

Bottom line - for others who may google their way here - I found the following suggestion here: Fixed and always visible footer below ListFragment

Try doing as follows, where the emphasis is on the button (or any footer element) listed first in the XML - and then the list is added as "layout_above":

<RelativeLayout>

<Button android:id="@+id/footer" android:layout_alignParentBottom="true"/> 
<ListView android:id="@android:id/list" **android:layout_above**="@id/footer"> <!-- the list -->

</RelativeLayout>

function alertWithoutNotice(message){
    setTimeout(function(){
        alert(message);
    }, 1000);
}

You can use codecs.

import codecs
with open("test.txt",'r') as filehandle:
    content = filehandle.read()
if content[:3] == codecs.BOM_UTF8:
    content = content[3:]
print content.decode("utf-8")

Use the Alert Interface, First switchTo() to alert and then either use accept() to click on OK or use dismiss() to CANCEL it

Alert alert_box = driver.switchTo().alert();
alert_box.accept(); 

or

Alert alert_box = driver.switchTo().alert();
alert_box.dismiss(); 

Fairly straightforward:

git remote rm origin

As for the filter-branch question - just add --prune-empty to your filter branch command and it'll remove any revision that doesn't actually contain any changes in your resulting repo:

git filter-branch --prune-empty --subdirectory-filter path/to/subtree HEAD

I think it would be handy to use Session.Clear() rather than using Session.Abandon().

Because the values still exist in session after calling later but are removed after calling the former.

The most voted answer has got already defined [String] function body. I was looking for the solution to rename already declared function's name and finally after an hour of struggling I've dealt with it. It:

• takes the alredy declared function
• parses it to [String] with .toString() method
• then overwrites the name (of named function) or appends the new one (when anonymous) between function and (
• then creates the new renamed function with new Function() constructor

function nameAppender(name,fun){_x000D_
  const reg = /^(function)(?:\s*|\s+([A-Za-z0-9_$]+)\s*)(\()/;_x000D_
  return (new Function(`return ${fun.toString().replace(reg,`$1 ${name}$3`)}`))();_x000D_
}_x000D_
_x000D_
//WORK FOR ALREADY NAMED FUNCTIONS:_x000D_
function hello(name){_x000D_
  console.log('hello ' + name);_x000D_
}_x000D_
_x000D_
//rename the 'hello' function_x000D_
var greeting = nameAppender('Greeting', hello); _x000D_
_x000D_
console.log(greeting); //function Greeting(name){...}_x000D_
_x000D_
_x000D_
//WORK FOR ANONYMOUS FUNCTIONS:_x000D_
//give the name for the anonymous function_x000D_
var count = nameAppender('Count',function(x,y){ _x000D_
  this.x = x;_x000D_
  this.y = y;_x000D_
  this.area = x*y;_x000D_
}); _x000D_
_x000D_
console.log(count); //function Count(x,y){...}

This is an adapted version of the answer given by Vivien Barousse with the update from Vulcan applied. In this example I use sliders to dynamically retreive the RGB values from three sliders and display that color in a rectangle. Then in method toHex() I use the values to create a color and display the respective Hex color code.

This example does not include the proper constraints for the GridBagLayout. Though the code will work, the display will look strange.

public class HexColor
{

  public static void main (String[] args)
  {
   JSlider sRed = new JSlider(0,255,1);
   JSlider sGreen = new JSlider(0,255,1);
   JSlider sBlue = new JSlider(0,255,1);
   JLabel hexCode = new JLabel();
   JPanel myPanel = new JPanel();
   GridBagLayout layout = new GridBagLayout();
   JFrame frame = new JFrame();

   //set frame to organize components using GridBagLayout 
   frame.setLayout(layout);

   //create gray filled rectangle 
   myPanel.paintComponent();
   myPanel.setBackground(Color.GRAY);

   //In practice this code is replicated and applied to sGreen and sBlue. 
   //For the sake of brevity I only show sRed in this post.
   sRed.addChangeListener(
         new ChangeListener()
         {
             @Override
             public void stateChanged(ChangeEvent e){
                 myPanel.setBackground(changeColor());
                 myPanel.repaint();
                 hexCode.setText(toHex());
         }
         }
     );
   //add each component to JFrame
   frame.add(myPanel);
   frame.add(sRed);
   frame.add(sGreen);
   frame.add(sBlue);
   frame.add(hexCode);
} //end of main

  //creates JPanel filled rectangle
  protected void paintComponent(Graphics g)
  {
      super.paintComponent(g);
      g.drawRect(360, 300, 10, 10);
      g.fillRect(360, 300, 10, 10);
  }

  //changes the display color in JPanel
  private Color changeColor()
  {
    int r = sRed.getValue();
    int b = sBlue.getValue();
    int g = sGreen.getValue();
    Color c;
    return  c = new Color(r,g,b);
  }

  //Displays hex representation of displayed color
  private String toHex()
  {
      Integer r = sRed.getValue();
      Integer g = sGreen.getValue();
      Integer b = sBlue.getValue();
      Color hC;
      hC = new Color(r,g,b);
      String hex = Integer.toHexString(hC.getRGB() & 0xffffff);
      while(hex.length() < 6){
          hex = "0" + hex;
      }
      hex = "Hex Code: #" + hex;
      return hex;
  }
}

A huge thank you to both Vivien and Vulcan. This solution works perfectly and was super simple to implement.

import os
for root, dirs, files in os.walk(top, topdown=False):
    for name in dirs:
        print os.path.join(root, name)

Walk is a good built-in for what you are doing

To Remove element from the list

objectA.removeIf(x -> conditions);

eg:

objectA.removeIf(x -> blockedWorkerIds.contains(x));

List<String> str1 = new ArrayList<String>();
str1.add("A");
str1.add("B");
str1.add("C");
str1.add("D");

List<String> str2 = new ArrayList<String>();
str2.add("D");
str2.add("E");

str1.removeIf(x -> str2.contains(x)); 

str1.forEach(System.out::println);

OUTPUT: A B C

Also make sure the value is not too large or too small for int like in my case.

Simplest form I ever found is...

List<String> lines = Files.readAllLines(Paths.get("/path/to/file.txt"));

First, I'd like to apologize for bringing this question back up, but I felt that it could use another answer.

Derek Schultz is kind of correct. The '\b' character moves the printing cursor one character backwards, allowing you to overwrite the character that was printed there (it does not delete the entire line or even the character that was there unless you print new information on top). The following is an example of a progress bar using Java though it does not follow your format, it shows how to solve the core problem of overwriting characters (this has only been tested in Ubuntu 12.04 with Oracle's Java 7 on a 32-bit machine, but it should work on all Java systems):

public class BackSpaceCharacterTest
{
    // the exception comes from the use of accessing the main thread
    public static void main(String[] args) throws InterruptedException
    {
        /*
            Notice the user of print as opposed to println:
            the '\b' char cannot go over the new line char.
        */
        System.out.print("Start[          ]");
        System.out.flush(); // the flush method prints it to the screen

        // 11 '\b' chars: 1 for the ']', the rest are for the spaces
        System.out.print("\b\b\b\b\b\b\b\b\b\b\b");
        System.out.flush();
        Thread.sleep(500); // just to make it easy to see the changes

        for(int i = 0; i < 10; i++)
        {
            System.out.print("."); //overwrites a space
            System.out.flush();
            Thread.sleep(100);
        }

        System.out.print("] Done\n"); //overwrites the ']' + adds chars
        System.out.flush();
    }
}

You need to start by understanding that the target of a symlink is a pathname. And it can be absolute or relative to the directory which contains the symlink

Assuming you have foo.conf in sites-available

Try

cd sites-enabled
sudo ln -s ../sites-available/foo.conf .
ls -l

Now you will have a symlink in sites-enabled called foo.conf which has a target ../sites-available/foo.conf

Just to be clear, the normal configuration for Apache is that the config files for potential sites live in sites-available and the symlinks for the enabled sites live in sites-enabled, pointing at targets in sites-available. That doesn't quite seem to be the case the way you describe your setup, but that is not your primary problem.

If you want a symlink to ALWAYS point at the same file, regardless of the where the symlink is located, then the target should be the full path.

ln -s /etc/apache2/sites-available/foo.conf mysimlink-whatever.conf

Here is (line 1 of) the output of my ls -l /etc/apache2/sites-enabled:

lrwxrwxrwx 1 root root  26 Jun 24 21:06 000-default -> ../sites-available/default

See how the target of the symlink is relative to the directory that contains the symlink (it starts with ".." meaning go up one directory).

Hardlinks are totally different because the target of a hardlink is not a directory entry but a filing system Inode.

sdas is being read as a variable. To input a string you need " "

Try this:

<form method="post" action="check.php">
    <select name="website_string">
        <option value="" selected="selected"></option>
        <option VALUE="abc"> ABC</option>
        <option VALUE="def"> def</option>
        <option VALUE="hij"> hij</option>
    </select>
    <input TYPE="submit" name="submit" />
</form>

Both your select control and your submit button had the same name attribute, so the last one used was the submit button when you clicked it. All other syntax errors aside.

check.php

<?php
    echo $_POST['website_string'];
?>

Obligatory disclaimer about using raw $_POST data. Sanitize anything you'll actually be using in application logic.

In the list of arguments, each entry must be on its own. Using

output = subprocess.check_output(["ping", "-c","2", "-W","2", "1.1.1.1"])

should fix your problem.

I ran into this problem as well. I am using an ant build script. I am working on a legacy application so I am using jdk version 1.4.2. This used to work so I started looking around. I noticed that under the Debug configuration on the JRE tab the version of Java had been set to 1.7. Once I changed it back to 1.4 it worked.

I hope this helps.

You Can use simply git checkout <commit hash>

in this sequence

bash git clone [URLTORepository] git checkout [commithash]

commit hash looks like this "45ef55ac20ce2389c9180658fdba35f4a663d204"

By default transaction propagation is REQUIRED, meaning that the same transaction will propagate from a transactional caller to transactional callee. In this case also the read-only status will propagate. E.g. if a read-only transaction will call a read-write transaction, the whole transaction will be read-only.

Could you use the Open Session in View pattern to allow lazy loading? That way your handle method does not need to be transactional at all.

As stated in the relevant RxJS documentation, the .subscribe() method can take a third argument that is called on completion if there are no errors.

For reference:

1. [onNext] (Function): Function to invoke for each element in the observable sequence.
2. [onError] (Function): Function to invoke upon exceptional termination of the observable sequence.
3. [onCompleted] (Function): Function to invoke upon graceful termination of the observable sequence.

Therefore you can handle your routing logic in the onCompleted callback since it will be called upon graceful termination (which implies that there won't be any errors when it is called).

this.httpService.makeRequest()
    .subscribe(
      result => {
        // Handle result
        console.log(result)
      },
      error => {
        this.errors = error;
      },
      () => {
        // 'onCompleted' callback.
        // No errors, route to new page here
      }
    );

As a side note, there is also a .finally() method which is called on completion regardless of the success/failure of the call. This may be helpful in scenarios where you always want to execute certain logic after an HTTP request regardless of the result (i.e., for logging purposes or for some UI interaction such as showing a modal).

Rx.Observable.prototype.finally(action)

Invokes a specified action after the source observable sequence terminates gracefully or exceptionally.

For instance, here is a basic example:

import { Observable } from 'rxjs/Rx';
import 'rxjs/add/operator/finally';

// ...

this.httpService.getRequest()
    .finally(() => {
      // Execute after graceful or exceptionally termination
      console.log('Handle logging logic...');
    })
    .subscribe (
      result => {
        // Handle result
        console.log(result)
      },
      error => {
        this.errors = error;
      },
      () => {
        // No errors, route to new page
      }
    );

You've declared @TEMP but in your insert statement used @temp. Case sensitive variable names.

Change @temp to @TEMP

If you are running the command from a POSIX-compliant shell, like bash, you can set the environment variable like this:

PYTHONPATH="/path/to" python somescript.py somecommand

If it's all on one line, the PYTHONPATH environment value applies only to that one command.

$ echo $PYTHONPATH

$ python -c 'import sys;print("/tmp/pydir" in sys.path)'
False
$ PYTHONPATH=/tmp/pydir python -c 'import sys;print("/tmp/pydir" in sys.path)'
True
$ echo $PYTHONPATH

You can also do this if you want to play around with pandas. However, I like punchagan's way.

# replicating your dataframe
lake = pd.DataFrame({'co tp': ['DE Lake', 'Forest', 'FR Lake', 'Forest'], 
                 'area': [10, 20, 30, 40], 
                 'count': [7, 5, 2, 3]})
lake.set_index('co tp', inplace=True)

# to get key value using pandas
area_dict = lake.set_index('area').T.to_dict('records')[0]
print(area_dict)

output: {10: 7, 20: 5, 30: 2, 40: 3}

No there is no built-in support for this.

You have to make your own "INIFileReader". Maybe something like this?

var data = new Dictionary<string, string>();
foreach (var row in File.ReadAllLines(PATH_TO_FILE))
  data.Add(row.Split('=')[0], string.Join("=",row.Split('=').Skip(1).ToArray()));

Console.WriteLine(data["ServerName"]);

Edit: Updated to reflect Paul's comment.

if you mean an anonymous function, and are using a version of Java before Java 8, then in a word, no. (Read about lambda expressions if you use Java 8+)

However, you can implement an interface with a function like so :

Comparator<String> c = new Comparator<String>() {
    int compare(String s, String s2) { ... }
};

and you can use this with inner classes to get an almost-anonymous function :)

Completely removed from java 8 +
Partially removed from java 7 (interned Strings for example)

I wrote a shorthand for permission request in Android M. This code also handles backwards compatibility to older Android versions.

All the ugly code is extracted into a Fragment which attaches and detaches itself to the Activity requesting the permissions.You can use PermissionRequestManager as following:

new PermissionRequestManager()
        // We need a AppCompatActivity here, if you are not using support libraries you will have to slightly change 
        // the PermissionReuqestManager class
        .withActivity(this)

        // List all permissions you need

i have experienced the same problem, and after reading this post i have double checked the JAVA_HOME definition in .bash_profile. It is actually:

export JAVA_HOME=$(which java)

that, exactly as Anony-Mousse is explaining, is the executable. Changing it to:

export=/Library/Java/Home

fixes the problem, tho is still interesting to understand why it's valued in that way in the profile file.

Testing for name pointing to None and name existing are two semantically different operations.

To check if val is None:

if val is None:
    pass  # val exists and is None

To check if name exists:

try:
    val
except NameError:
    pass  # val does not exist at all

If your working on embedded projects or specialized platforms static libraries are the only way to go, also many times they are less of a hassle to compile into your application. Also having projects and makefile that include everything makes life happier.

I like ZenBurn theme, I think it is very mild and appealing for the eye. I had here my own theme's settings JAR file, but I stopped updating it. I still think that theme is very good so I updated this post to a suitable theme with similar colors which is already available on @Yarg's web site

Link towards the theme

I've created a service + filter that could help you guys with this, and maybe also with some other providers if you choose to add them in the future.

Check out https://github.com/mgonto/angularytics and let me know how this works out for you.

You can also use Json.NET.

return JsonConvert.SerializeObject(jsonResult.Data);

curl -d @request.json --header "Content-Type: application/json" https://www.googleapis.com/qpxExpress/v1/trips/search?key=mykeyhere

its python implementation be like

import requests

headers = {
    'Content-Type': 'application/json',
}

params = (
    ('key', 'mykeyhere'),
)

data = open('request.json')
response = requests.post('https://www.googleapis.com/qpxExpress/v1/trips/search', headers=headers, params=params, data=data)

#NB. Original query string below. It seems impossible to parse and
#reproduce query strings 100% accurately so the one below is given
#in case the reproduced version is not "correct".
# response = requests.post('https://www.googleapis.com/qpxExpress/v1/trips/search?key=mykeyhere', headers=headers, data=data)

check this link, it will help convert cURl command to python,php and nodejs

Set your SMTP auth to true if using the PHPmailer class:

$mail->SMTPAuth = true;

It is an extremely overused way to check for the success/failure of a command. Typically, the code snippet you give would be refactored as:

if grep -e ERROR ${LOG_DIR_PATH}/${LOG_NAME} > /dev/null; then
   ...
fi

(Although you can use 'grep -q' in some instances instead of redirecting to /dev/null, doing so is not portable. Many implementations of grep do not support the -q option, so your script may fail if you use it.)

If you are using Angular 2 (apparently it also works for Angular 4 too), you can use the following to round to two decimal places{{ exampleNumber | number : '1.2-2' }}, as in:

<ion-input value="{{ exampleNumber | number : '1.2-2' }}"></ion-input>

BREAKDOWN

'1.2-2' means {minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}:

• A minimum of 1 digit will be shown before decimal point
• It will show at least 2 digits after decimal point
• But not more than 2 digits

I faced the same issue:

E: gnupg, gnupg2 and gnupg1 do not seem to be installed, but one of them is required for this operation

I resolved by using the following commands:

apt-get update
apt-get install gnupg

You can also make additions to this path with the PYTHONPATH environment variable at runtime, in addition to:

import sys
sys.path.append('/home/user/python-libs')

import traceback
traceback.print_stack()

1. There's no need to call equals if hashCode differs.
2. There's no need to call hashCode if (obj1 == obj2).
3. There's no need for hashCode and/or equals just to iterate - you're not comparing objects
4. When needed to distinguish in between objects.

Check this library, it's completable with booth bootstrap 3 and bootstrap 4

jQuery

<form>
    <div class="form-group">
        <input class="form-control" data-validator="required|min:4|max:10">
    </div>
</form>

Javascript

$(document).on('blur', '[data-validator]', function () {
    new Validator($(this));
});

So, you want an 8-character wide field with spaces as the padding? Try "%8d". Here's a reference.

EDIT: What you're trying to do is not something that can be handled by printf alone, because it will not know what the longest number you are writing is. You will need to calculate the largest number before doing any printfs, and then figure out how many digits to use as the width of your field. Then you can use snprintf or similar to make a printf format on the spot.

char format[20];
snprintf(format, 19, "%%%dd\\n", max_length);
while (got_output) {
    printf(format, number);
    got_output = still_got_output();
}

I get the same error in WP when I use php ver 7.1.6 - just take your php version back to 7.0.20 and the error will disappear.

Super simple in-place assignment: df['new'] = 0

For in-place modification, perform direct assignment. This assignment is broadcasted by pandas for each row.

df = pd.DataFrame('x', index=range(4), columns=list('ABC'))
df

   A  B  C
0  x  x  x
1  x  x  x
2  x  x  x
3  x  x  x

df['new'] = 'y'
# Same as,
# df.loc[:, 'new'] = 'y'
df

   A  B  C new
0  x  x  x   y
1  x  x  x   y
2  x  x  x   y
3  x  x  x   y

Note for object columns

If you want to add an column of empty lists, here is my advice:

• Consider not doing this. object columns are bad news in terms of performance. Rethink how your data is structured.
• Consider storing your data in a sparse data structure. More information: sparse data structures

• If you must store a column of lists, ensure not to copy the same reference multiple times.

  # Wrong
  df['new'] = [[]] * len(df)
  # Right
  df['new'] = [[] for _ in range(len(df))]
  

Generating a copy: df.assign(new=0)

If you need a copy instead, use DataFrame.assign:

df.assign(new='y')

   A  B  C new
0  x  x  x   y
1  x  x  x   y
2  x  x  x   y
3  x  x  x   y

And, if you need to assign multiple such columns with the same value, this is as simple as,

c = ['new1', 'new2', ...]
df.assign(**dict.fromkeys(c, 'y'))

   A  B  C new1 new2
0  x  x  x    y    y
1  x  x  x    y    y
2  x  x  x    y    y
3  x  x  x    y    y

Multiple column assignment

Finally, if you need to assign multiple columns with different values, you can use assign with a dictionary.

c = {'new1': 'w', 'new2': 'y', 'new3': 'z'}
df.assign(**c)

   A  B  C new1 new2 new3
0  x  x  x    w    y    z
1  x  x  x    w    y    z
2  x  x  x    w    y    z
3  x  x  x    w    y    z

In cmd you can use the following:

c:\your directory\your folder\build>java -jar yourFile.jar 

However, you need to create you .jar file on your project if you use Netbeans. How just go to Run ->Clean and Build Project(your project name)

Also make sure you project properties Build->Packing has a yourFile.jar and check Build JAR after Compiling check Copy Depentent Libraries

Warning: Make sure your Environmental variables for Java are properly set.

Old way to compile and run a Java File from the command prompt (cmd)

Compiling: c:\>javac Myclass.java
Running: c:\>java com.myPackage.Myclass

I hope this info help.

127.0.0.1 is normally the IP address assigned to the "loopback" or local-only interface. This is a "fake" network adapter that can only communicate within the same host. It's often used when you want a network-capable application to only serve clients on the same host. A process that is listening on 127.0.0.1 for connections will only receive local connections on that socket.

"localhost" is normally the hostname for the 127.0.0.1 IP address. It's usually set in /etc/hosts (or the Windows equivalent named "hosts" somewhere under %WINDIR%). You can use it just like any other hostname - try "ping localhost" to see how it resolves to 127.0.0.1.

0.0.0.0 has a couple of different meanings, but in this context, when a server is told to listen on 0.0.0.0 that means "listen on every available network interface". The loopback adapter with IP address 127.0.0.1 from the perspective of the server process looks just like any other network adapter on the machine, so a server told to listen on 0.0.0.0 will accept connections on that interface too.

That hopefully answers the IP side of your question. I'm not familiar with Jekyll or Vagrant, but I'm guessing that your port forwarding 8080 => 4000 is somehow bound to a particular network adapter, so it isn't in the path when you connect locally to 127.0.0.1

You may want to use a different structure altogether, but there are ways to do it in python 2.7.

d1 = OrderedDict([('a', '1'), ('b', '2')])
d2 = OrderedDict(c='3')
d2.update(d1)

d2 will then contain

>>> d2
OrderedDict([('c', '3'), ('a', '1'), ('b', '2')])

As mentioned by others, in python 3.2 you can use OrderedDict.move_to_end('c', last=False) to move a given key after insertion.

Note: Take into consideration that the first option is slower for large datasets due to creation of a new OrderedDict and copying of old values.

1. Set var step=1 as global variable by putting it above the function call
2. put semicolons

It will look like this

<head>
<script type="text/javascript">
var image1 = new Image()
image1.src = "images/pentagg.jpg"
var image2 = new Image()
image2.src = "images/promo.jpg"
</script>
</head>
<body>
<p><img src="images/pentagg.jpg" width="500" height="300" name="slide" /></p>
<script type="text/javascript">
        var step=1;
        function slideit()
        {
            document.images.slide.src = eval("image"+step+".src");
            if(step<2)
                step++;
            else
                step=1;
            setTimeout("slideit()",2500);
        }
        slideit();
</script>
</body>

It would help to have sample information about your output. Recursively using rbind on bigger and bigger things is not recommended. My first guess at something that would help you:

z <- list(1:3,4:6,7:9)
do.call(rbind,z)

See a related question for more efficiency, if needed.

It is not htop-like, but you could use atop. However, to display disk activity per process, it needs a kernel patch (available from the site). These kernel patches are now obsoleted, only to show per-process network activity an optional module is provided.

Never use escape(). It's nothing to do with HTML-encoding. It's more like URL-encoding, but it's not even properly that. It's a bizarre non-standard encoding available only in JavaScript.

If you want an HTML encoder, you'll have to write it yourself as JavaScript doesn't give you one. For example:

function encodeHTML(s) {
    return s.replace(/&/g, '&amp;').replace(/</g, '&lt;').replace(/"/g, '&quot;');
}

However whilst this is enough to put your user_id in places like the input value, it's not enough for id because IDs can only use a limited selection of characters. (And % isn't among them, so escape() or even encodeURIComponent() is no good.)

You could invent your own encoding scheme to put any characters in an ID, for example:

function encodeID(s) {
    if (s==='') return '_';
    return s.replace(/[^a-zA-Z0-9.-]/g, function(match) {
        return '_'+match[0].charCodeAt(0).toString(16)+'_';
    });
}

But you've still got a problem if the same user_id occurs twice. And to be honest, the whole thing with throwing around HTML strings is usually a bad idea. Use DOM methods instead, and retain JavaScript references to each element, so you don't have to keep calling getElementById, or worrying about how arbitrary strings are inserted into IDs.

eg.:

function addChut(user_id) {
    var log= document.createElement('div');
    log.className= 'log';
    var textarea= document.createElement('textarea');
    var input= document.createElement('input');
    input.value= user_id;
    input.readonly= True;
    var button= document.createElement('input');
    button.type= 'button';
    button.value= 'Message';

    var chut= document.createElement('div');
    chut.className= 'chut';
    chut.appendChild(log);
    chut.appendChild(textarea);
    chut.appendChild(input);
    chut.appendChild(button);
    document.getElementById('chuts').appendChild(chut);

    button.onclick= function() {
        alert('Send '+textarea.value+' to '+user_id);
    };

    return chut;
}

You could also use a convenience function or JS framework to cut down on the lengthiness of the create-set-appends calls there.

ETA:

I'm using jQuery at the moment as a framework

OK, then consider the jQuery 1.4 creation shortcuts, eg.:

var log= $('<div>', {className: 'log'});
var input= $('<input>', {readOnly: true, val: user_id});
...

The problem I have right now is that I use JSONP to add elements and events to a page, and so I can not know whether the elements already exist or not before showing a message.

You can keep a lookup of user_id to element nodes (or wrapper objects) in JavaScript, to save putting that information in the DOM itself, where the characters that can go in an id are restricted.

var chut_lookup= {};
...

function getChut(user_id) {
    var key= '_map_'+user_id;
    if (key in chut_lookup)
        return chut_lookup[key];
    return chut_lookup[key]= addChut(user_id);
}

(The _map_ prefix is because JavaScript objects don't quite work as a mapping of arbitrary strings. The empty string and, in IE, some Object member names, confuse it.)

string firstdayofyear = new DateTime(DateTime.Now.Year, 1, 1).ToString("MM-dd-yyyy");
string lastdayofyear = new DateTime(DateTime.Now.Year, 12, 31).ToString("MM-dd-yyyy");
string firstdayofmonth = new DateTime(DateTime.Now.Year, DateTime.Now.Month, 1).ToString("MM-dd-yyyy");
string lastdayofmonth = new DateTime(DateTime.Now.Year, DateTime.Now.Month, 1).AddMonths(1).AddDays(-1).ToString("MM-dd-yyyy");

A slightly more concise example that builds on top of the other answers here. I leveraged the code generation that is shipped with Visual Studio to remove most of the extra invocation code and replaced it with typed objects instead.

If you just want to change the legend title, you can do the following:

import seaborn as sns
import matplotlib.pyplot as plt
tips = sns.load_dataset("tips")

g = sns.lmplot(
    x="total_bill", 
    y="tip", 
    hue="smoker", 
    data=tips,  
    legend=True
)

g._legend.set_title("New Title")

If you use old version of MySQL you can always use \P combined with some nice piece of awk code. Interesting example here

Isn't it exactly what you need?

Edit: This library is now available through Bower and NPM. See github repo for details.

UPDATED ANSWER:

• Live example: CodePen
• Latest version: Github repository
• Don't like Bootstrap? Check: Foundation demo and Custom framework demos
• Have a problem? Open an issue

Disclaimer: I'm the author.

Here's a few things you can do using the latest version (Responsive Bootstrap Toolkit 2.5.0):

// Wrap everything in an IIFE
(function($, viewport){

    // Executes only in XS breakpoint
    if( viewport.is('xs') ) {
        // ...
    }

    // Executes in SM, MD and LG breakpoints
    if( viewport.is('>=sm') ) {
        // ...
    }

    // Executes in XS and SM breakpoints
    if( viewport.is('<md') ) {
        // ...
    }

    // Execute only after document has fully loaded
    $(document).ready(function() {
        if( viewport.is('xs') ) {
            // ...
        }
    });

    // Execute code each time window size changes
    $(window).resize(
        viewport.changed(function() {
            if( viewport.is('xs') ) {
                // ...
            }
        })
    ); 

})(jQuery, ResponsiveBootstrapToolkit);

As of version 2.3.0, you don't need the four <div> elements mentioned below.

ORIGINAL ANSWER:

I don't think you need any huge script or library for that. It's a fairly simple task.

Insert the following elements just before </body>:

<div class="device-xs visible-xs"></div>
<div class="device-sm visible-sm"></div>
<div class="device-md visible-md"></div>
<div class="device-lg visible-lg"></div>

These 4 divs allow you check for currently active breakpoint. For an easy JS detection, use the following function:

function isBreakpoint( alias ) {
    return $('.device-' + alias).is(':visible');
}

Now to perform a certain action only on the smallest breakpoint you could use:

if( isBreakpoint('xs') ) {
    $('.someClass').css('property', 'value');
}

Detecting changes after DOM ready is also fairly simple. All you need is a lightweight window resize listener like this one:

var waitForFinalEvent = function () {
      var b = {};
      return function (c, d, a) {
        a || (a = "I am a banana!");
        b[a] && clearTimeout(b[a]);
        b[a] = setTimeout(c, d)
      }
    }();

var fullDateString = new Date();

Once you're equipped with it, you can start listening for changes and execute breakpoint-specific functions like so:

$(window).resize(function () {
    waitForFinalEvent(function(){

        if( isBreakpoint('xs') ) {
            $('.someClass').css('property', 'value');
        }

    }, 300, fullDateString.getTime())
});

You can define an interface as array with simply extending the Array interface.

export interface MyInterface extends Array<MyType> { }

With this, any object which implements the MyInterface will need to implement all function calls of arrays and only will be able to store objects with the MyType type.

The comments above are correct. You're missing the decorators. If you want a generic deserializer you can use this.

public static T DeserializeXMLFileToObject<T>(string XmlFilename)
{
    T returnObject = default(T);
    if (string.IsNullOrEmpty(XmlFilename)) return default(T);

    try
    {
        StreamReader xmlStream = new StreamReader(XmlFilename);
        XmlSerializer serializer = new XmlSerializer(typeof(T));
        returnObject = (T)serializer.Deserialize(xmlStream);
    }
    catch (Exception ex)
    {
        ExceptionLogger.WriteExceptionToConsole(ex, DateTime.Now);
    }
    return returnObject;
}

Then you'd call it like this:

MyObjType MyObj = DeserializeXMLFileToObject<MyObjType>(FilePath);

facing similar problem to you. In my case I have 1000's of files from cisco logs that I need to parse manually.

In order to be flexible with fields and types I have successfully tested using StringIO + read_cvs which indeed does accept a dict for the dtype specification.

I usually get each of the files ( 5k-20k lines) into a buffer and create the dtype dictionaries dynamically.

Eventually I concatenate ( with categorical... thanks to 0.19) these dataframes into a large data frame that I dump into hdf5.

Something along these lines

import pandas as pd
import io 

output = io.StringIO()
output.write('A,1,20,31\n')
output.write('B,2,21,32\n')
output.write('C,3,22,33\n')
output.write('D,4,23,34\n')

output.seek(0)


df=pd.read_csv(output, header=None,
        names=["A","B","C","D"],
        dtype={"A":"category","B":"float32","C":"int32","D":"float64"},
        sep=","
       )

df.info()

<class 'pandas.core.frame.DataFrame'>
RangeIndex: 5 entries, 0 to 4
Data columns (total 4 columns):
A    5 non-null category
B    5 non-null float32
C    5 non-null int32
D    5 non-null float64
dtypes: category(1), float32(1), float64(1), int32(1)
memory usage: 205.0 bytes
None

Not very pythonic.... but does the job

Hope it helps.

I had the similar issue using Flurl.Http:

Flurl.Http.FlurlHttpException: Call failed. Cannot send a content-body with this verb-type. GET http://******:8301/api/v1/agents/**** ---> System.Net.ProtocolViolationException: Cannot send a content-body with this verb-type.

The problem was I used .WithHeader("Content-Type", "application/json") when creating IFlurlRequest.

If after you confirm your Bundle ID's match across App Store Connect, Apple Developer Portal, and Xcode and you are still having issues try this:

Remove the Apple ID associated with the Bundle ID you're experiencing issues with from your Accounts list in Xcode (Menu Bar -> Xcode -> Preferences -> Accounts). Then, add the Apple ID back to the Accounts list in Xcode.

You can use the regex "\W".This matches any non-word character.The required line would be:

String[] tokens=pdfName.split("\\W");

You can't. Nginx doesn't really support variables in config files, and its developers mock everyone who ask for this feature to be added:

"[Variables] are rather costly compared to plain static configuration. [A] macro expansion and "include" directives should be used [with] e.g. sed + make or any other common template mechanism." http://nginx.org/en/docs/faq/variables_in_config.html

You should either write or download a little tool that will allow you to generate config files from placeholder config files.

Update The code below still works, but I've wrapped it all up into a small PHP program/library called Configurator also on Packagist, which allows easy generation of nginx/php-fpm etc config files, from templates and various forms of config data.

e.g. my nginx source config file looks like this:

location  / {
    try_files $uri /routing.php?$args;
    fastcgi_pass   unix:%phpfpm.socket%/php-fpm-www.sock;
    include       %mysite.root.directory%/conf/fastcgi.conf;
}

And then I have a config file with the variables defined:

phpfpm.socket=/var/run/php-fpm.socket
mysite.root.directory=/home/mysite

And then I generate the actual config file using that. It looks like you're a Python guy, so a PHP based example may not help you, but for anyone else who does use PHP:

<?php

require_once('path.php');

$filesToGenerate = array(
    'conf/nginx.conf' => 'autogen/nginx.conf',
    'conf/mysite.nginx.conf' => 'autogen/mysite.nginx.conf',
    'conf/mysite.php-fpm.conf' => 'autogen/mysite.php-fpm.conf',
    'conf/my.cnf' => 'autogen/my.cnf',
);

$environment = 'amazonec2';

if ($argc >= 2){
    $environmentRequired = $argv[1];

    $allowedVars = array(
        'amazonec2',
        'macports',
    );

    if (in_array($environmentRequired, $allowedVars) == true){
        $environment = $environmentRequired;
    }
}
else{
    echo "Defaulting to [".$environment."] environment";
}

$config = getConfigForEnvironment($environment);

foreach($filesToGenerate as $inputFilename => $outputFilename){
    generateConfigFile(PATH_TO_ROOT.$inputFilename, PATH_TO_ROOT.$outputFilename, $config);
}


function    getConfigForEnvironment($environment){
    $config = parse_ini_file(PATH_TO_ROOT."conf/deployConfig.ini", TRUE);
    $configWithMarkers = array();
    foreach($config[$environment] as $key => $value){
        $configWithMarkers['%'.$key.'%'] = $value;
    }

    return  $configWithMarkers;
}


function    generateConfigFile($inputFilename, $outputFilename, $config){

    $lines = file($inputFilename);

    if($lines === FALSE){
        echo "Failed to read [".$inputFilename."] for reading.";
        exit(-1);
    }

    $fileHandle = fopen($outputFilename, "w");

    if($fileHandle === FALSE){
        echo "Failed to read [".$outputFilename."] for writing.";
        exit(-1);
    }

    $search = array_keys($config);
    $replace = array_values($config);

    foreach($lines as $line){
        $line = str_replace($search, $replace, $line);
        fwrite($fileHandle, $line);
    }

    fclose($fileHandle);
}

?>

And then deployConfig.ini looks something like:

[global]

;global variables go here.

[amazonec2]
nginx.log.directory = /var/log/nginx
nginx.root.directory = /usr/share/nginx
nginx.conf.directory = /etc/nginx
nginx.run.directory  = /var/run
nginx.user           = nginx

[macports]
nginx.log.directory = /opt/local/var/log/nginx
nginx.root.directory = /opt/local/share/nginx
nginx.conf.directory = /opt/local/etc/nginx
nginx.run.directory  = /opt/local/var/run
nginx.user           = _www

For completeness:

Along the lines of Chase's answer, I usually use as.data.frame to coerce the matrix to a data.frame:

m <- as.data.frame(matrix(0, ncol = 30, nrow = 2))

EDIT: speed test data.frame vs. as.data.frame

system.time(replicate(10000, data.frame(matrix(0, ncol = 30, nrow = 2))))
   user  system elapsed 
  8.005   0.108   8.165 

system.time(replicate(10000, as.data.frame(matrix(0, ncol = 30, nrow = 2))))
   user  system elapsed 
  3.759   0.048   3.802 

Yes, it appears to be faster (by about 2 times).

Check out this blog post here that talks about the same thing. From what I gather, the extra time might have to do with walking up the scope chain.

Also you can check using Keras backend function:

from keras import backend as K
K.tensorflow_backend._get_available_gpus()

I test this on Keras (2.1.1)

from selenium import webdriver

driver = webdriver.Firefox()
driver.implicitly_wait(12)
driver.set_page_load_timeout(10)

def _post_selenium(self, url: str, data: dict):
    input_template = '{k} <input type="text" name="{k}" id="{k}" value="{v}"><BR>\n'
    inputs = ""
    if data:
        for k, v in data.items():
            inputs += input_template.format(k=k, v=v)
    html = f'<html><body>\n<form action="{url}" method="post" id="formid">\n{inputs}<input type="submit" id="inputbox">\n</form></body></html>'

    html_file = os.path.join(os.getcwd(), 'temp.html')
    with open(html_file, "w") as text_file:
        text_file.write(html)

    driver.get(f"file://{html_file}")
    driver.find_element_by_id('inputbox').click()

_post_selenium("post.to.my.site.url", {"field1": "val1"})

driver.close()

Lets start from the beginning.

First of all, accept the principle that certain simple operations on data can be done in O(1) time, that is, in time that is independent of the size of the input. These primitive operations in C consist of

1. Arithmetic operations (e.g. + or %).
2. Logical operations (e.g., &&).
3. Comparison operations (e.g., <=).
4. Structure accessing operations (e.g. array-indexing like A[i], or pointer fol- lowing with the -> operator).
5. Simple assignment such as copying a value into a variable.
6. Calls to library functions (e.g., scanf, printf).

The justification for this principle requires a detailed study of the machine instructions (primitive steps) of a typical computer. Each of the described operations can be done with some small number of machine instructions; often only one or two instructions are needed. As a consequence, several kinds of statements in C can be executed in O(1) time, that is, in some constant amount of time independent of input. These simple include

1. Assignment statements that do not involve function calls in their expressions.
2. Read statements.
3. Write statements that do not require function calls to evaluate arguments.
4. The jump statements break, continue, goto, and return expression, where expression does not contain a function call.

In C, many for-loops are formed by initializing an index variable to some value and incrementing that variable by 1 each time around the loop. The for-loop ends when the index reaches some limit. For instance, the for-loop

for (i = 0; i < n-1; i++) 
{
    small = i;
    for (j = i+1; j < n; j++)
        if (A[j] < A[small])
            small = j;
    temp = A[small];
    A[small] = A[i];
    A[i] = temp;
}

uses index variable i. It increments i by 1 each time around the loop, and the iterations stop when i reaches n - 1.

However, for the moment, focus on the simple form of for-loop, where the difference between the final and initial values, divided by the amount by which the index variable is incremented tells us how many times we go around the loop. That count is exact, unless there are ways to exit the loop via a jump statement; it is an upper bound on the number of iterations in any case.

For instance, the for-loop iterates ((n - 1) - 0)/1 = n - 1 times, since 0 is the initial value of i, n - 1 is the highest value reached by i (i.e., when i reaches n-1, the loop stops and no iteration occurs with i = n-1), and 1 is added to i at each iteration of the loop.

In the simplest case, where the time spent in the loop body is the same for each iteration, we can multiply the big-oh upper bound for the body by the number of times around the loop. Strictly speaking, we must then add O(1) time to initialize the loop index and O(1) time for the first comparison of the loop index with the limit, because we test one more time than we go around the loop. However, unless it is possible to execute the loop zero times, the time to initialize the loop and test the limit once is a low-order term that can be dropped by the summation rule.

Now consider this example:

(1) for (j = 0; j < n; j++)
(2)   A[i][j] = 0;

We know that line (1) takes O(1) time. Clearly, we go around the loop n times, as we can determine by subtracting the lower limit from the upper limit found on line (1) and then adding 1. Since the body, line (2), takes O(1) time, we can neglect the time to increment j and the time to compare j with n, both of which are also O(1). Thus, the running time of lines (1) and (2) is the product of n and O(1), which is O(n).

Similarly, we can bound the running time of the outer loop consisting of lines (2) through (4), which is

(2) for (i = 0; i < n; i++)
(3)     for (j = 0; j < n; j++)
(4)         A[i][j] = 0;

We have already established that the loop of lines (3) and (4) takes O(n) time. Thus, we can neglect the O(1) time to increment i and to test whether i < n in each iteration, concluding that each iteration of the outer loop takes O(n) time.

The initialization i = 0 of the outer loop and the (n + 1)st test of the condition i < n likewise take O(1) time and can be neglected. Finally, we observe that we go around the outer loop n times, taking O(n) time for each iteration, giving a total O(n^2) running time.

A more practical example.

In case .empty() doesn't work for you, which is for me

function SetDropDownToEmpty() 
{           
$('#dropdown').find('option').remove().end().append('<option value="0"></option>');
$("#dropdown").trigger("liszt:updated");          
}

$(document).ready(
SetDropDownToEmpty() ;
)

if you don't export default in A, B, C but just export {} then it's possible to do so

// things/A.js
export function A() {}

// things/B.js
export function B() {}

// things/C.js
export function C() {}

// foo.js
import * as Foo from ./thing
Foo.A()
Foo.B()
Foo.C()

1) Almost-English style:

Test for presence using the in operator, then apply the remove method.

if thing in some_list: some_list.remove(thing)

The removemethod will remove only the first occurrence of thing, in order to remove all occurrences you can use while instead of if.

while thing in some_list: some_list.remove(thing)    

• Simple enough, probably my choice.for small lists (can't resist one-liners)

2) Duck-typed, EAFP style:

This shoot-first-ask-questions-last attitude is common in Python. Instead of testing in advance if the object is suitable, just carry out the operation and catch relevant Exceptions:

try:
    some_list.remove(thing)
except ValueError:
    pass # or scream: thing not in some_list!
except AttributeError:
    call_security("some_list not quacking like a list!")

Off course the second except clause in the example above is not only of questionable humor but totally unnecessary (the point was to illustrate duck-typing for people not familiar with the concept).

If you expect multiple occurrences of thing:

while True:
    try:
        some_list.remove(thing)
    except ValueError:
        break

• a little verbose for this specific use case, but very idiomatic in Python.
• this performs better than #1
• PEP 463 proposed a shorter syntax for try/except simple usage that would be handy here, but it was not approved.

However, with contextlib's suppress() contextmanager (introduced in python 3.4) the above code can be simplified to this:

with suppress(ValueError, AttributeError):
    some_list.remove(thing)

Again, if you expect multiple occurrences of thing:

with suppress(ValueError):
    while True:
        some_list.remove(thing)

3) Functional style:

Around 1993, Python got lambda, reduce(), filter() and map(), courtesy of a Lisp hacker who missed them and submitted working patches*. You can use filter to remove elements from the list:

is_not_thing = lambda x: x is not thing
cleaned_list = filter(is_not_thing, some_list)

There is a shortcut that may be useful for your case: if you want to filter out empty items (in fact items where bool(item) == False, like None, zero, empty strings or other empty collections), you can pass None as the first argument:

cleaned_list = filter(None, some_list)

• [update]: in Python 2.x, filter(function, iterable) used to be equivalent to [item for item in iterable if function(item)] (or [item for item in iterable if item] if the first argument is None); in Python 3.x, it is now equivalent to (item for item in iterable if function(item)). The subtle difference is that filter used to return a list, now it works like a generator expression - this is OK if you are only iterating over the cleaned list and discarding it, but if you really need a list, you have to enclose the filter() call with the list() constructor.
• *These Lispy flavored constructs are considered a little alien in Python. Around 2005, Guido was even talking about dropping filter - along with companions map and reduce (they are not gone yet but reduce was moved into the functools module, which is worth a look if you like high order functions).

4) Mathematical style:

List comprehensions became the preferred style for list manipulation in Python since introduced in version 2.0 by PEP 202. The rationale behind it is that List comprehensions provide a more concise way to create lists in situations where map() and filter() and/or nested loops would currently be used.

cleaned_list = [ x for x in some_list if x is not thing ]

Generator expressions were introduced in version 2.4 by PEP 289. A generator expression is better for situations where you don't really need (or want) to have a full list created in memory - like when you just want to iterate over the elements one at a time. If you are only iterating over the list, you can think of a generator expression as a lazy evaluated list comprehension:

for item in (x for x in some_list if x is not thing):
    do_your_thing_with(item)

• See this Python history blog post by GvR.
• This syntax is inspired by the set-builder notation in math.
• Python 3 has also set and dict comprehensions.

Notes

1. you may want to use the inequality operator != instead of is not (the difference is important)
2. for critics of methods implying a list copy: contrary to popular belief, generator expressions are not always more efficient than list comprehensions - please profile before complaining

There's no built-in command for it, so I usually just do something like this:

#!/bin/bash

# history_of_file
#
# Outputs the full history of a given file as a sequence of
# logentry/diff pairs.  The first revision of the file is emitted as
# full text since there's not previous version to compare it to.

function history_of_file() {
    url=$1 # current url of file
    svn log -q $url | grep -E -e "^r[[:digit:]]+" -o | cut -c2- | sort -n | {

#       first revision as full text
        echo
        read r
        svn log -r$r $url@HEAD
        svn cat -r$r $url@HEAD
        echo

#       remaining revisions as differences to previous revision
        while read r
        do
            echo
            svn log -r$r $url@HEAD
            svn diff -c$r $url@HEAD
            echo
        done
    }
}

Then, you can call it with:

history_of_file $1

3. Under the IIS section, open "Server Certificates"

4. Click "Create Self-Signed Certificate"

5. Name it "localhost" (or something like that that is not specific)

6. Click "OK"

You can then bind that certificate to your website...

1. Right click on your website and choose "Edit bindings..."

2. Click "Add"

   • Type: https
   • IP address: "All Unassigned"
   • Port: 443
   • SSL certificate: "localhost"

3. Click "OK"

4. Click "Close"

I solved the issue by adding this import

If you are sure you're only ever working with images, you can check out the getimagesize() exif_imagetype() PHP function, which attempts to return the image mime-type.

If you don't mind external dependencies, you can also check out the excellent getID3 library which can determine the mime-type of many different file types.

Lastly, you can check out the mime_content_type() function - but it has been deprecated for the Fileinfo PECL extension.

Here's a possibile solution (in Python):

Let's say you have a notebook with a file name, call it Notebook.ipynb. You are currently working in that notebook, and want to access other folders and files around it. Here's it's path:

import os
notebook_path = os.path.abspath("Notebook.ipynb")

In other words, just use the os module, and get the absolute path of your notebook (it's a file, too!). From there, use the os module and your path to navigate.

For example, if your train.csv is in a folder called 'Datasets', and the notebook is sitting right next to that folder, you could get the data like this:

train_csv = os.path.join(os.path.dirname(notebook_path), "Datasets/train.csv")
with open(train_csv) as file:
    #....etc

The takeaway is that the notebook has a file name, and as long as your language supports pathname manipulations (e.g. the os module in Python) you can likely use the notebook filename.

Lastly, the reason your code fails is probably because you're either trying to access local files (like your Mac's 'Downloads' folder) when you're working in an online Notebook (like Kaggle, which hosts your environment for you, online and away from your Mac), or you moved or deleted something in that path. This is what the os module in Python is meant to do; it will find the file's path whether it's on your Mac or in a Kaggle server.

You got an extra } to many as seen below:

var nav = document.getElementsByClassName('nav-coll');
for (var i = 0; i < button.length; i++) {
    nav[i].addEventListener('click',function(){
            console.log('haha');
        } // <-- REMOVE THIS :)
    }, false);
};

A very good tool for those things is jsFiddle. I have created a fiddle with your invalid code and when clicking the TidyUp button it formats your code which makes it clearer if there are any possible mistakes with missing braces.

DEMO - Your code in a fiddle, have a play :)

With JavaScript version 1.6 it's as easy as this:

Array.prototype.equals = function( array ) {
  return this.length == array.length && 
         this.every( function(this_i,i) { return this_i == array[i] } )  
  }

For example, [].equals([]) gives true, while [1,2,3].equals( [1,3,2] ) yields false.

I think you want to lowercase the checked value? Try:

var jIsHasKids = $('#chkIsHasKids:checked').val().toLowerCase();

or you want to check it, then get its value as lowercase:

var jIsHasKids = $('#chkIsHasKids').attr("checked", true).val().toLowerCase();

I am surprised that there isn't more information posted about Solr. Solr is quite similar to Sphinx but has more advanced features (AFAIK as I haven't used Sphinx -- only read about it).

The answer at the link below details a few things about Sphinx which also applies to Solr. Comparison of full text search engine - Lucene, Sphinx, Postgresql, MySQL?

Solr also provides the following additional features:

1. Supports replication
2. Multiple cores (think of these as separate databases with their own configuration and own indexes)
3. Boolean searches
4. Highlighting of keywords (fairly easy to do in application code if you have regex-fu; however, why not let a specialized tool do a better job for you)
5. Update index via XML or delimited file
6. Communicate with the search server via HTTP (it can even return Json, Native PHP/Ruby/Python)
7. PDF, Word document indexing
8. Dynamic fields
9. Facets
10. Aggregate fields
11. Stop words, synonyms, etc.
12. More Like this...
13. Index directly from the database with custom queries
14. Auto-suggest
15. Cache Autowarming
16. Fast indexing (compare to MySQL full-text search indexing times) -- Lucene uses a binary inverted index format.
17. Boosting (custom rules for increasing relevance of a particular keyword or phrase, etc.)
18. Fielded searches (if a search user knows the field he/she wants to search, they narrow down their search by typing the field, then the value, and ONLY that field is searched rather than everything -- much better user experience)

BTW, there are tons more features; however, I've listed just the features that I have actually used in production. BTW, out of the box, MySQL supports #1, #3, and #11 (limited) on the list above. For the features you are looking for, a relational database isn't going to cut it. I'd eliminate those straight away.

Also, another benefit is that Solr (well, Lucene actually) is a document database (e.g. NoSQL) so many of the benefits of any other document database can be realized with Solr. In other words, you can use it for more than just search (i.e. Performance). Get creative with it :)

Sorry, Im a newbie myself and I had this issue:

./hello.py: line 1: syntax error near unexpected token "Hello World"' ./hello.py: line 1:print("Hello World")'

I added the file header for the python 'deal' as #!/usr/bin/python

Then simple executed the program with './hello.py'

Normally it happens when the target is null. So better check the invoke target first then do the linq query.

I have Windows 8 installed on my machine, and the aspnet_regiis.exe tool did not worked for me either.

The solution that worked for me is posted on this link, on the answer by Neha: System.ServiceModel.Activation.HttpModule error

Everywhere the problem to this solution was mentioned as re-registering aspNet by using aspnet_regiis.exe. But this did not work for me.

Though this is a valid solution (as explained beautifully here)

but it did not work with Windows 8.

For Windows 8 you need to Windows features and enable everything under ".Net Framework 3.5" and ".Net Framework 4.5 Advanced Services".

Thanks Neha

You can't do it with the HTML5 input type. There are many libs available to do it, you can use momentjs or some other jQuery UI components for the best outcome.

It looks as though the horizontal axis (Category Group) labels have very long values - there may not be room to display them all. I suggest changing the labels to have shorter values.

You can set the sort order for the Category Groups in the Category Group Properties - Sorting section - this may have been previously set; if not, I suggest using this to sort as desired.

HttpClient is new in .net 4.5. You should probably be using HttpWebRequest.

For me the Web API was Rails and client side Angular used with Restangular and FileSaver.js

Web API

module Api
  module V1
    class DownloadsController < BaseController

      def show
        @download = Download.find(params[:id])
        send_data @download.blob_data
      end
    end
  end
end

HTML

 <a ng-click="download('foo')">download presentation</a>

Angular controller

 $scope.download = function(type) {
    return Download.get(type);
  };

Angular Service

'use strict';

app.service('Download', function Download(Restangular) {

  this.get = function(id) {
    return Restangular.one('api/v1/downloads', id).withHttpConfig({responseType: 'arraybuffer'}).get().then(function(data){
      console.log(data)
      var blob = new Blob([data], {
        type: "application/pdf"
      });
      //saveAs provided by FileSaver.js
      saveAs(blob, id + '.pdf');
    })
  }
});

@main:

$ su
$ yum install MySQL-python

and it will be installed (MySQLdb).

Adding the lines below in the .typingsrc file helped me.

{
    "rejectUnauthorized": false,
    "registryURL" :"http://api.typings.org/"
 }

The problem seems to be in the way how ng-model works with input and overwrites the name object, making it lost for ng-repeat.

As a workaround, one can use the following code:

<div ng-repeat="name in names">
    Value: {{name}}
    <input ng-model="names[$index]">                         
</div>

Hope it helps

The Git URL will be inside the Git configuration file. The value corresponds to the key url.

For Mac and Linux use the commands below:

 cd project_dir
 cat .git/config | grep url | awk '{print $3}'

For Windows open the below file in any text editor and find the value for key url.

project_dir/.git/config

Note: This will work even if you are offline or the remote git server has been taken down.

You can't put a pseudo element in an input element, but can put in shadow element, like a placeholder!

input[type="text"] {   
  &::-webkit-input-placeholder {
    &:before {
      // your code
    }
  }
}

To make it work in other browsers, use :-moz-placeholder, ::-moz-placeholder and :-ms-input-placeholder in different selectors. Can't group the selectors, because if a browser doesn't recognize the selector invalidates the entire statement.

UPDATE: The above code works only with CSS pre-processor (SASS, LESS...), without pre-processors use:

input[type="text"]::-webkit-input-placeholder:before { // your code }

Use this:

static int RandomNumber(int min, int max)
{
    Random random = new Random(); return random.Next(min, max);

}

This is example for you to modify and use in your application.

If the first segment doesn't start with / it is a relative route. router.navigate needs a relativeTo parameter for relative navigation

Either you make the route absolute:

this.router.navigate(['/foo-content', 'bar-contents', 'baz-content', 'page'], this.params.queryParams)

or you pass relativeTo

this.router.navigate(['../foo-content', 'bar-contents', 'baz-content', 'page'], {queryParams: this.params.queryParams, relativeTo: this.currentActivatedRoute})

Nearly all modern browsers now support the use of the maxlength attribute for textarea elements.(https://caniuse.com/#feat=maxlength)

To include the maxlength attribute on a multiline TextBox, you can simply modify the Attributes collection in the code behind like so:

txtTextBox.Attributes["maxlength"] = "100";

If you don't want to have to use the code behind to specify that, you can just create a custom control that derives from TextBox:

public class Textarea : TextBox
{
    public override TextBoxMode TextMode
    {
        get { return TextBoxMode.MultiLine; }
        set { }
    }

    protected override void OnPreRender(EventArgs e)
    {
        if (TextMode == TextBoxMode.MultiLine && MaxLength != 0)
        {
            Attributes["maxlength"] = MaxLength.ToString();
        }

        base.OnPreRender(e);
    }
}

Problem with data-dismiss="modal" is it will shift your content to left

I am sharing what worked for me, problem statment was opening pop1 from pop2

I don't understand how can datenwolf`s index generation can be correct. But still I find his solution rather clear. This is what I get after some thinking:

inline void push_indices(vector<GLushort>& indices, int sectors, int r, int s) {
    int curRow = r * sectors;
    int nextRow = (r+1) * sectors;

    indices.push_back(curRow + s);
    indices.push_back(nextRow + s);
    indices.push_back(nextRow + (s+1));

    indices.push_back(curRow + s);
    indices.push_back(nextRow + (s+1));
    indices.push_back(curRow + (s+1));
}

void createSphere(vector<vec3>& vertices, vector<GLushort>& indices, vector<vec2>& texcoords,
             float radius, unsigned int rings, unsigned int sectors)
{
    float const R = 1./(float)(rings-1);
    float const S = 1./(float)(sectors-1);

    for(int r = 0; r < rings; ++r) {
        for(int s = 0; s < sectors; ++s) {
            float const y = sin( -M_PI_2 + M_PI * r * R );
            float const x = cos(2*M_PI * s * S) * sin( M_PI * r * R );
            float const z = sin(2*M_PI * s * S) * sin( M_PI * r * R );

            texcoords.push_back(vec2(s*S, r*R));
            vertices.push_back(vec3(x,y,z) * radius);
            push_indices(indices, sectors, r, s);
        }
    }
}

On this page, the Arduino sketch defines a couple of Structs (plus a couple of methods) which are then called in the setup loop and main loop. Simple enough to interpret, even for a barely-literate programmer like me.

Like has been mentioned already the progress field needs the keyword event

public event EventHandler<Progress> progress;

But I don't think that's where you actually want your event. I think you actually want the event in TestClass. How does the following look? (I've never actually tried setting up static events so I'm not sure if the following will compile or not, but I think this gives you an idea of the pattern you should be aiming for.)

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        TestClass.progress += SetStatus;
    }

    private void SetStatus(object sender, Progress e)
    {
        label1.Text = e.Status;
    }

    private void button1_Click_1(object sender, EventArgs e)
    {
         TestClass.Func();
    }

 }

public class TestClass
{
    public static event EventHandler<Progress> progress; 

    public static void Func()
    {
        //time consuming code
        OnProgress(new Progress("current status"));
        // time consuming code
        OnProgress(new Progress("some new status"));            
    }

    private static void OnProgress(EventArgs e) 
    {
       if (progress != null)
          progress(this, e);
    }
}


public class Progress : EventArgs
{
    public string Status { get; private set; }

    private Progress() {}

    public Progress(string status)
    {
        Status = status;
    }
}

function saveAs(uri, filename) {
    var link = document.createElement('a');
    if (typeof link.download === 'string') {
        document.body.appendChild(link); // Firefox requires the link to be in the body
        link.download = filename;
        link.href = uri;
        link.click();
        document.body.removeChild(link); // remove the link when done
    } else {
        location.replace(uri);
    }
}

To add a WHERE clause inside an INSERT statement simply;

INSERT INTO table_name (column1,column2,column3)
SELECT column1, column2, column3 FROM  table_name
WHERE column1 = 'some_value'

The key lies in the differences between references and instances and what the reference can promise and what the instance can really do.

ArrayList<A> a = new ArrayList<A>();

Here a is a reference to an instance of a specific type - exactly an array list of As. More explicitly, a is a reference to an array list that will accept As and will produce As. new ArrayList<A>() is an instance of an array list of As, that is, an array list that will accept As and will produce As.

ArrayList<Integer> a = new ArrayList<Number>(); 

Here, a is a reference to exactly an array list of Integers, i.e. exactly an array list that can accept Integers and will produce Integers. It cannot point to an array list of Numbers. That array list of Numbers can not meet all the promises of ArrayList<Integer> a (i.e. an array list of Numbers may produce objects that are not Integers, even though its empty right then).

ArrayList<Number> a = new ArrayList<Integer>(); 

Here, declaration of a says that a will refer to exactly an array list of Numbers, that is, exactly an array list that will accept Numbers and will produce Numbers. It cannot point to an array list of Integers, because the type declaration of a says that a can accept any Number, but that array list of Integers cannot accept just any Number, it can only accept Integers.

ArrayList<? extends Object> a= new ArrayList<Object>();

Here a is a (generic) reference to a family of types rather than a reference to a specific type. It can point to any list that is member of that family. However, the trade-off for this nice flexible reference is that they cannot promise all of the functionality that it could if it were a type-specific reference (e.g. non-generic). In this case, a is a reference to an array list that will produce Objects. But, unlike a type-specific list reference, this a reference cannot accept any Object. (i.e. not every member of the family of types that a can point to can accept any Object, e.g. an array list of Integers can only accept Integers.)

ArrayList<? super Integer> a = new ArrayList<Number>();

Again, a is a reference to a family of types (rather than a single specific type). Since the wildcard uses super, this list reference can accept Integers, but it cannot produce Integers. Said another way, we know that any and every member of the family of types that a can point to can accept an Integer. However, not every member of that family can produce Integers.

PECS - Producer extends, Consumer super - This mnemonic helps you remember that using extends means the generic type can produce the specific type (but cannot accept it). Using super means the generic type can consume (accept) the specific type (but cannot produce it).

ArrayList<ArrayList<?>> a

An array list that holds references to any list that is a member of a family of array lists types.

= new ArrayList<ArrayList<?>>(); // correct

An instance of an array list that holds references to any list that is a member of a family of array lists types.

ArrayList<?> a

An reference to any array list (a member of the family of array list types).

= new ArrayList<?>()

ArrayList<?> refers to any type from a family of array list types, but you can only instantiate a specific type.

See also How can I add to List<? extends Number> data structures?

I know this was posted a long while ago, and it has been marked answered, but to me, the selected answer was not answering the question I thought the user was posing. It seemed to me he was looking for the approach one can take in ASP .Net that corresponds to his inline data binding previously performed in php.

Here was his php:

<p>Here is the username: <?php echo GetUserName(); ?></p>

Here is what one would do in ASP .Net:

<p>Here is the username: <%= GetUserName() %></p>

I found this problem too. Because centos service depend on multi-user.target for none desktop Cenots 7.2. so I delete multi-user.target from my .service file. It had missed.

Follow these steps

1. Add cors dependency. type the following in cli inside your project directory

npm install --save cors

2. Include the module inside your project

var cors = require('cors');

3. Finally use it as a middleware.

app.use(cors());

A perfect working code..

    <script>
    var objConnection = new ActiveXObject("adodb.connection");
    var strConn = "driver={sql server};server=QITBLRQIPL030;database=adventureworks;uid=sa;password=12345";
    objConnection.Open(strConn);
    var rs = new ActiveXObject("ADODB.Recordset");
    var strQuery = "SELECT * FROM  Person.Address";
    rs.Open(strQuery, objConnection);
    rs.MoveFirst();
    while (!rs.EOF) {
        document.write(rs.fields(0) + "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;");
        document.write(rs.fields(1) + "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;");
        document.write(rs.fields(2) + "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;    ");
        document.write(rs.fields(3) + "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;    ");
        document.write(rs.fields(4) + "<br/>");
        rs.movenext();
    }
</script>

One can use the textract library. It take care of both "doc" as well as "docx"

import textract
text = textract.process("path/to/file.extension")

You can even use 'antiword' (sudo apt-get install antiword) and then convert doc to first into docx and then read through docx2txt.

antiword filename.doc > filename.docx

Ultimately, textract in the backend is using antiword.

Go to mirror.olnevhost.net/pub/apache/maven/binaries/ and check what is the latest tar.gz file

Supposing it is e.g. apache-maven-3.2.1-bin.tar.gz, from the command line; you should be able to simply do:

wget http://mirror.olnevhost.net/pub/apache/maven/binaries/apache-maven-3.2.1-bin.tar.gz

And then proceed to install it.

   tar xvf apache-maven-3.2.1-bin.tar.gz
   

3. Next add the env varibles such as

   export M2_HOME=/usr/local/apache-maven/apache-maven-3.2.1

   export M2=$M2_HOME/bin

   export PATH=$M2:$PATH

4. Verify

   mvn -version
   

Like this:

#include <vector>

// ...

std::vector<std::vector<int>> A(dimension, std::vector<int>(dimension));

(Pre-C++11 you need to leave whitespace between the angled brackets.)

An example of how to do this using a lambda expression would be:

issublist = lambda x, y: 0 in [_ in x for _ in y]

You have to set to element_blank() in theme() elements you need to remove

ggplot(data = diamonds, mapping = aes(x = clarity)) + geom_bar(aes(fill = cut))+
  theme(axis.title.x=element_blank(),
        axis.text.x=element_blank(),
        axis.ticks.x=element_blank())

You can check an example in Plunker over here plunker example filters

filter() {

    let storeId = 1;
    this.bookFilteredList = this.bookList
                                .filter((book: Book) => book.storeId === storeId);
    this.bookList = this.bookFilteredList; 
}

You can't do this, which is by design. The Django framework authors intended a strict separation of presentation code from data logic. Filtering models is data logic, and outputting HTML is presentation logic.

So you have several options. The easiest is to do the filtering, then pass the result to render_to_response. Or you could write a method in your model so that you can say {% for object in data.filtered_set %}. Finally, you could write your own template tag, although in this specific case I would advise against that.

EDITED: The best solution is using NavigationEvents, you don't need to create listeners manually :)

Calling a callback function is not highly recommended, check this example using a listener (Remember to remove all listeners from componentWillUnMount with this option)

Component A

navigateToComponentB() {
  const { navigation } = this.props
  this.navigationListener = navigation.addListener('willFocus', payload => {
    this.removeNavigationListener()
    const { state } = payload
    const { params } = state
    //update state with the new params
    const { otherParam } = params
    this.setState({ otherParam })
  })
  navigation.push('ComponentB', {
    returnToRoute: navigation.state,
    otherParam: this.state.otherParam
  })
}
removeNavigationListener() {
  if (this.navigationListener) {
    this.navigationListener.remove()
    this.navigationListener = null
  }
}
componentWillUnmount() {
  this.removeNavigationListener()
}

Commponent B

returnToComponentA() {
  const { navigation } = this.props
  const { routeName, key } = navigation.getParam('returnToRoute')
  navigation.navigate({ routeName, key, params: { otherParam: 123 } })
}

In my case, a pod with an initContainer failed to initialize. Running docker ps -a and then docker logs exited-container-id-here gave me a log message which kubectl logs podname didn't display. Mystery solved :-)

In my case, it goes well after I installed CMake in my system:)

sudo pacman -S cmake

for manjaro operating system.

More simply you can utilize DropBox for this. The steps basically remain the same. You can do the following-:

1) upload your .ipa to dropBox, Share the link for this .ipa

2) Paste the shared link for .ipa in your manifest.plist file , Upload manifest file in DropBox again share the link for this .plist file

3)paste the link for this Plist in your index.html file with a suitable tag.

Share this index.html file with anybody who can tap on the URL and download. or you can directly hit the URL instead.

Do you want to do this?

SELECT id, parent_id, name, 
 (select Name from tbl where id = t.parent_id) parent_name
FROM tbl t start with id = 1 CONNECT BY PRIOR id = parent_id

Edit Another option based on OMG's one (but I think that will perform equally):

select 
           t1.id, 
           t1.parent_id, 
           t1.name,
           t2.name AS parent_name,
           t2.id AS parent_id
from 
    (select id, parent_id, name
    from tbl
    start with id = 1 
    connect by prior id = parent_id) t1
    left join
    tbl t2 on t2.id = t1.parent_id

The Pragmatic programmer was pretty good. However one that really made an impact when I was starting out was :

Windows 95 System Programming Secrets"

I know - it sounds and looks a bit cheesy on the outside and has probably dated a bit - but this was an awesome explanation of the internals of Win95 based on the Authors (Matt Pietrek) investigations using his own own tools - the code for which came with the book. Bear in mind this was before the whole open source thing and Microsoft was still pretty cagey about releasing documentation of internals - let alone source. There was some quote in there like "If you are working through some problem and hit some sticking point then you need to stop and really look deeply into that piece and really understand how it works". I've found this to be pretty good advice - particularly these days when you often have the source for a library and can go take a look. Its also inspired me to enjoy diving into the internals of how systems work, something that has proven invaluable over the course of my career.

Oh and I'd also throw in effective .net - great internals explanation of .Net from Don Box.

function doosomething ()
{
  //Doo something
}


$(function () {


  $("div.class").click(doosomething);

  $("div.secondclass").click(doosomething);

});

Andrey Tarasevich provides the following explanation:

1. On Google Groups
2. On bytes.com

[Minor changes to formatting made. Parenthetical annotations added in square brackets []].

The whole idea of using 'do/while' version is to make a macro which will expand into a regular statement, not into a compound statement. This is done in order to make the use of function-style macros uniform with the use of ordinary functions in all contexts.

Consider the following code sketch:

if (<condition>)
  foo(a);
else
  bar(a);

where foo and bar are ordinary functions. Now imagine that you'd like to replace function foo with a macro of the above nature [named CALL_FUNCS]:

if (<condition>)
  CALL_FUNCS(a);
else
  bar(a);

Now, if your macro is defined in accordance with the second approach (just { and }) the code will no longer compile, because the 'true' branch of if is now represented by a compound statement. And when you put a ; after this compound statement, you finished the whole if statement, thus orphaning the else branch (hence the compilation error).

One way to correct this problem is to remember not to put ; after macro "invocations":

if (<condition>)
  CALL_FUNCS(a)
else
  bar(a);

This will compile and work as expected, but this is not uniform. The more elegant solution is to make sure that macro expand into a regular statement, not into a compound one. One way to achieve that is to define the macro as follows:

#define CALL_FUNCS(x) \
do { \
  func1(x); \
  func2(x); \
  func3(x); \
} while (0)

Now this code:

if (<condition>)
  CALL_FUNCS(a);
else
  bar(a);

will compile without any problems.

However, note the small but important difference between my definition of CALL_FUNCS and the first version in your message. I didn't put a ; after } while (0). Putting a ; at the end of that definition would immediately defeat the entire point of using 'do/while' and make that macro pretty much equivalent to the compound-statement version.

I don't know why the author of the code you quoted in your original message put this ; after while (0). In this form both variants are equivalent. The whole idea behind using 'do/while' version is not to include this final ; into the macro (for the reasons that I explained above).

If you are using VBA to enter formulas, it is possible to accidentally enter them incompletely:

Sub AlmostAFormula()
    With Range("A1")
        .Clear
        .NumberFormat = "@"
        .Value = "=B1+C1"
        .NumberFormat = "General"
    End With
End Sub

A1 will appear to have a formula, but it is only text until you double-click the cell and touch Enter .

Make sure you have no bugs like this in your code.

You can use this code to check whether the input string contains any spaces?

public static void main(String[]args)
{
    Scanner sc=new Scanner(System.in);
    System.out.println("enter the string...");
    String s1=sc.nextLine();
    int l=s1.length();
    int count=0;
    for(int i=0;i<l;i++)
    {
        char c=s1.charAt(i);
        if(c==' ')
        {
        System.out.println("spaces are in the position of "+i);
        System.out.println(count++);
        }
        else
        {
        System.out.println("no spaces are there");
    }
}

Calling addView is the correct answer, but you need to do a little more than that to get it to work.

If you create a View via a constructor (e.g., Button myButton = new Button();), you'll need to call setLayoutParams on the newly constructed view, passing in an instance of the parent view's LayoutParams inner class, before you add your newly constructed child to the parent view.

For example, you might have the following code in your onCreate() function assuming your LinearLayout has id R.id.main:

LinearLayout myLayout = findViewById(R.id.main);

Button myButton = new Button(this);
myButton.setLayoutParams(new LinearLayout.LayoutParams(
                                     LinearLayout.LayoutParams.MATCH_PARENT,
                                     LinearLayout.LayoutParams.MATCH_PARENT));

myLayout.addView(myButton);

Making sure to set the LayoutParams is important. Every view needs at least a layout_width and a layout_height parameter. Also getting the right inner class is important. I struggled with getting Views added to a TableRow to display properly until I figured out that I wasn't passing an instance of TableRow.LayoutParams to the child view's setLayoutParams.

class="mb-0"

m - sets margin

b - sets bottom margin or padding

0 - sets 0 margin or padding

CSS class

.mb-0{
       margin-bottom: 0
     }

You need to edit your PATH environmental variable to make sure wherever the homebrew python is located is searched before /usr/bin. You could also set things up in your shell config to have a variable like PYTHON be set to your desired version of python and call $PYTHON rather than python from the command line.

Also, as another poster stated (and especially on mac) DO NOT mess with the python in /usr/bin to point it to another python install. You're just asking for trouble if you do.

I don't think putting %AppData% in a string like that will work.

Update all your code that calls load function like,

$(window).load(function() { ... });

To

$(window).on('load', function() { ... });

jquery.js:9612 Uncaught TypeError: url.indexOf is not a function

This error message comes from jQuery.fn.load function.

I've come across the same issue on my application. After some digging, I found this statement in jQuery blog,

.load, .unload, and .error, deprecated since jQuery 1.8, are no more. Use .on() to register listeners.

I simply just change how my jQuery objects call the load function like above. And everything works as expected.

$("#Create").find(".myClass").add("#Edit .myClass").plugin({});

Use $.fn.add to concatenate two sets.

If you want to change a foreign key without dropping it you can do:

ALTER TABLE child_table_name  WITH CHECK ADD FOREIGN KEY(child_column_name)
REFERENCES parent_table_name (parent_column_name) ON DELETE CASCADE

• Open Notepad++
• Paste your text
• Control + H

In the pop up

• Find what: \r\n
• Replace with: BLANK_SPACE

You end up with a big line. Then

• Control + H

In the pop up

• Find what: (\.)
• Replace with: \r\n

So you end up with lines that end by dot

And if you have to do the same process lots of times

• Go to Macro
• Start recording
• Do the process above
• Go to Macro
• Stop recording
• Save current recorded macro
• Choose a short cut
• Select the text you want to apply the process (Control + A)
• Do the shortcut

my two pence, using map in place of for-loop

var path = require('path'), fs = require('fs');

var findFiles = function(folder, pattern = /.*/, callback) {
  var flist = [];

  fs.readdirSync(folder).map(function(e){ 
    var fname = path.join(folder, e);
    var fstat = fs.lstatSync(fname);
    if (fstat.isDirectory()) {
      // don't want to produce a new array with concat
      Array.prototype.push.apply(flist, findFiles(fname, pattern, callback)); 
    } else {
      if (pattern.test(fname)) {
        flist.push(fname);
        if (callback) {
          callback(fname);
        }
      }
    }
  });
  return flist;
};

// HTML files   
var html_files = findFiles(myPath, /\.html$/, function(o) { console.log('look what we have found : ' + o} );

// All files
var all_files = findFiles(myPath);

Pure javascript version of Vidas's answer, el$ is the DOM node of the plane you are scrolling.

function onlyScrollElement(event, el$) {
    var delta = event.wheelDelta || -event.detail;
    el$.scrollTop += (delta < 0 ? 1 : -1) * 10;
    event.preventDefault();
}

Make sure you dont attach the even multiple times! Here is an example,

var ul$ = document.getElementById('yo-list');
// IE9, Chrome, Safari, Opera
ul$.removeEventListener('mousewheel', onlyScrollElement);
ul$.addEventListener('mousewheel', onlyScrollElement);
// Firefox
ul$.removeEventListener('DOMMouseScroll', onlyScrollElement);
ul$.addEventListener('DOMMouseScroll', onlyScrollElement);

Word of caution, the function there needs to be a constant, if you reinitialize the function each time before attaching it, ie. var func = function (...) the removeEventListener will not work.

You have a date with a known timezone (Here Europe/Madrid), and a target timezone (UTC)

You just need two SimpleDateFormats:

        long ts = System.currentTimeMillis();
        Date localTime = new Date(ts);

        SimpleDateFormat sdfLocal = new SimpleDateFormat ("yyyy/MM/dd HH:mm:ss");
        sdfLocal.setTimeZone(TimeZone.getTimeZone("Europe/Madrid"));

        SimpleDateFormat sdfUTC = new SimpleDateFormat ("yyyy/MM/dd HH:mm:ss");
        sdfUTC.setTimeZone(TimeZone.getTimeZone("UTC"));

        // Convert Local Time to UTC
        Date utcTime = sdfLocal.parse(sdfUTC.format(localTime));
        System.out.println("Local:" + localTime.toString() + "," + localTime.getTime() + " --> UTC time:" + utcTime.toString() + "-" + utcTime.getTime());

        // Reverse Convert UTC Time to Locale time
        localTime = sdfUTC.parse(sdfLocal.format(utcTime));
        System.out.println("UTC:" + utcTime.toString() + "," + utcTime.getTime() + " --> Local time:" + localTime.toString() + "-" + localTime.getTime());

So after see it working you can add this method to your utils:

    public Date convertDate(Date dateFrom, String fromTimeZone, String toTimeZone) throws ParseException {
        String pattern = "yyyy/MM/dd HH:mm:ss";
        SimpleDateFormat sdfFrom = new SimpleDateFormat (pattern);
        sdfFrom.setTimeZone(TimeZone.getTimeZone(fromTimeZone));

        SimpleDateFormat sdfTo = new SimpleDateFormat (pattern);
        sdfTo.setTimeZone(TimeZone.getTimeZone(toTimeZone));

        Date dateTo = sdfFrom.parse(sdfTo.format(dateFrom));
        return dateTo;
    }

I've been verifying calls in the same manner - I believe it is the right way to do it.

mockSomething.Verify(ms => ms.Method(
    It.IsAny<int>(), 
    It.Is<MyObject>(mo => mo.Id == 5 && mo.description == "test")
  ), Times.Once());

If your lambda expression becomes unwieldy, you could create a function that takes MyObject as input and outputs true/false...

mockSomething.Verify(ms => ms.Method(
    It.IsAny<int>(), 
    It.Is<MyObject>(mo => MyObjectFunc(mo))
  ), Times.Once());

private bool MyObjectFunc(MyObject myObject)
{
  return myObject.Id == 5 && myObject.description == "test";
}

Also, be aware of a bug with Mock where the error message states that the method was called multiple times when it wasn't called at all. They might have fixed it by now - but if you see that message you might consider verifying that the method was actually called.

EDIT: Here is an example of calling verify multiple times for those scenarios where you want to verify that you call a function for each object in a list (for example).

foreach (var item in myList)
  mockRepository.Verify(mr => mr.Update(
    It.Is<MyObject>(i => i.Id == item.Id && i.LastUpdated == item.LastUpdated),
    Times.Once());

Same approach for setup...

foreach (var item in myList) {
  var stuff = ... // some result specific to the item
  this.mockRepository
    .Setup(mr => mr.GetStuff(item.itemId))
    .Returns(stuff);
}

So each time GetStuff is called for that itemId, it will return stuff specific to that item. Alternatively, you could use a function that takes itemId as input and returns stuff.

this.mockRepository
    .Setup(mr => mr.GetStuff(It.IsAny<int>()))
    .Returns((int id) => SomeFunctionThatReturnsStuff(id));

One other method I saw on a blog some time back (Phil Haack perhaps?) had setup returning from some kind of dequeue object - each time the function was called it would pull an item from a queue.

I Think this is the best way to do it.

REPLACE(CONVERT(NVARCHAR,CAST(WeekEnding AS DATETIME), 106), ' ', '-')

Because you do not have to use varchar(11) or varchar(10) that can make problem in future.

With JQM 1.4.2 this one works for me (Change theme to the used one):

.ui-page-theme-b, .ui-page-theme-b .ui-panel-wrapper {
    background: transparent url(../img/xxx) !important;
    background-repeat:repeat !important;
}

Assuming join wasn't designed that way (which it is, as ATOzTOA pointed out), and it only took two parameters, you could still use the built-in reduce:

>>> reduce(os.path.join,["c:/","home","foo","bar","some.txt"])
'c:/home\\foo\\bar\\some.txt'

Same output like:

>>> os.path.join(*["c:/","home","foo","bar","some.txt"])
'c:/home\\foo\\bar\\some.txt' 

Just for completeness and educational reasons (and for other situations where * doesn't work).

Hint for Python 3

reduce was moved to the functools module.
