You're comparing apples to oranges here:

• webHttpBinding is the REST-style binding, where you basically just hit a URL and get back a truckload of XML or JSON from the web service

• basicHttpBinding and wsHttpBinding are two SOAP-based bindings which is quite different from REST. SOAP has the advantage of having WSDL and XSD to describe the service, its methods, and the data being passed around in great detail (REST doesn't have anything like that - yet). On the other hand, you can't just browse to a wsHttpBinding endpoint with your browser and look at XML - you have to use a SOAP client, e.g. the WcfTestClient or your own app.

So your first decision must be: REST vs. SOAP (or you can expose both types of endpoints from your service - that's possible, too).

Then, between basicHttpBinding and wsHttpBinding, there differences are as follows:

• basicHttpBinding is the very basic binding - SOAP 1.1, not much in terms of security, not much else in terms of features - but compatible to just about any SOAP client out there --> great for interoperability, weak on features and security

• wsHttpBinding is the full-blown binding, which supports a ton of WS-* features and standards - it has lots more security features, you can use sessionful connections, you can use reliable messaging, you can use transactional control - just a lot more stuff, but wsHttpBinding is also a lot *heavier" and adds a lot of overhead to your messages as they travel across the network

For an in-depth comparison (including a table and code examples) between the two check out this codeproject article: Differences between BasicHttpBinding and WsHttpBinding

There should be a way to solve this pretty easily with external config sections and an extra deployment step that drops a deployment specific external .config file into a known location. We typically use this solution to handle the different server configurations for our different deployment environments (Staging, QA, production, etc) with our "dev box" being the default if no special copy occurs.

You also need to increase maxBufferSize. Also note that you might need to increase the readerQuotas.

I have had this problem frequently with multiple concurrent goroutines.

It may or may not be a good pattern, but I define a a struct for my workers with a quit channel and field for the worker state:

type Worker struct {
    data chan struct
    quit chan bool
    stopped bool
}

Then you can have a controller call a stop function for the worker:

func (w *Worker) Stop() {
    w.quit <- true
    w.stopped = true
}

func (w *Worker) eventloop() {
    for {
        if w.Stopped {
            return
        }
        select {
            case d := <-w.data:
                //DO something
                if w.Stopped {
                    return
                }
            case <-w.quit:
                return
        }
    }
}

This gives you a pretty good way to get a clean stop on your workers without anything hanging or generating errors, which is especially good when running in a container.

There's no readily available syntax to do this in the original Markdown syntax, but Markdown Extra provides a means to at least assign IDs to headers — which you can then link to easily. Note also that you can use regular HTML in both Markdown and Markdown Extra, and that the name attribute has been superseded by the id attribute in more recent versions of HTML.

Not doing the correct level of normalization. You want to make sure that data is not duplicated, and that you are splitting data into different as needed. You also need to make sure you are not following normalization too far as that will hurt performance.

This formula reflects @RHSeeger's thought as a simple solution to get (in this example) the last day of the 3rd month (month of date in cell A1 + 4 with the first day of that month minus 1 day):

=DATE(YEAR(A1);MONTH(A1)+4;1)-1

Very precise, inclusive February's in leap years :)

Use this:

alert($(".messageCheckbox").is(":checked").val())

This assumes the checkboxes to check have the class "messageCheckbox", otherwise you would have to do a check if the input is the checkbox type, etc.

This is important information that I found on fragments:

Historically each screen in an Android app was implemented as a separate Activity. This creates a challenge in passing information between screens because the Android Intent mechanism does not allow passing a reference type (i.e. object) directly between Activities. Instead the object must be serialized or a globally accessible reference made available.

By making each screen a separate Fragment, this data passing headache is completely avoided. Fragments always exist within the context of a given Activity and can always access that Activity. By storing the information of interest within the Activity, the Fragment for each screen can simply access the object reference through the Activity.

The characters '<', and '>', are to indicate a place-holder, you should remove them to read:

php /usr/local/solusvm/scripts/pass.php --type=admin --comm=change --username=ADMINUSERNAME

Use groupby and count:

In [37]:
df = pd.DataFrame({'a':list('abssbab')})
df.groupby('a').count()

Out[37]:

   a
a   
a  2
b  3
s  2

[3 rows x 1 columns]

See the online docs: https://pandas.pydata.org/pandas-docs/stable/user_guide/groupby.html

Also value_counts() as @DSM has commented, many ways to skin a cat here

In [38]:
df['a'].value_counts()

Out[38]:

b    3
a    2
s    2
dtype: int64

If you wanted to add frequency back to the original dataframe use transform to return an aligned index:

In [41]:
df['freq'] = df.groupby('a')['a'].transform('count')
df

Out[41]:

   a freq
0  a    2
1  b    3
2  s    2
3  s    2
4  b    3
5  a    2
6  b    3

[7 rows x 2 columns]

This is a nice example: The Repository Pattern Example in C#

Basically, repository hides the details of how exactly the data is being fetched/persisted from/to the database. Under the covers:

• for reading, it creates the query satisfying the supplied criteria and returns the result set
• for writing, it issues the commands necessary to make the underlying persistence engine (e.g. an SQL database) save the data

I'm using

Sheet1.Range("E2", "E3000").NumberFormat = "dd/mm/yyyy hh:mm:ss"

to format a column

So I guess

Sheet1.Range("E2", "E3000").NumberFormat = "MMM dd yyyy"

would do the trick for you.

More: NumberFormat function.

Or if one want to use lambda function in the apply function:

data['Revenue']=data['Revenue'].apply(lambda x:float(x.replace("$","").replace(",", "").replace(" ", "")))

If you want to avoid npm install and not running in browser, you can also use nodejs https module;

const https = require('https')
const url = "https://jsonmock.hackerrank.com/api/movies";
https.get(url, res => {
  let data = '';
  res.on('data', chunk => {
    data += chunk;
  });
  res.on('end', () => {
    data = JSON.parse(data);
    console.log(data);
  })
}).on('error', err => {
  console.log(err.message);
})

You could use LINQ, but I would go with RemoveAll method. I think that is the one that better expresses your intent.

var integers = new List<int> { 1, 2, 3, 4, 5 };

var remove = new List<int> { 1, 3, 5 };

integers.RemoveAll(i => remove.Contains(i));

Use List.AddRange(collection As IEnumerable(Of T)) method.

It allows you to append at the end of your list another collection/list.

Example:

List<string> initialList = new List<string>();
// Put whatever you want in the initial list
List<string> listToAdd = new List<string>();
// Put whatever you want in the second list
initialList.AddRange(listToAdd);

A simpler way to explain this,

public bool CheckInputs(int a, int b){
public bool condition = true;

if (a > b || a == b)
{
   condition = false;
}
else
{
   condition = true;
}

return condition;
}

I know that this question has a lot of answers, and I'm sure must (if not all) are correct. However it was very hard for me to understand the logic/flow of these answers.

So I looked at the Original Implementation on Promise.all(), and I tried to imitate that logic - with the exception of not stopping the execution if one Promise failed.

  public promiseExecuteAll(promisesList: Promise<any>[] = []): Promise<{ data: any, isSuccess: boolean }[]>
  {
    let promise: Promise<{ data: any, isSuccess: boolean }[]>;

    if (promisesList.length)
    {
      const result: { data: any, isSuccess: boolean }[] = [];
      let count: number = 0;

      promise = new Promise<{ data: any, isSuccess: boolean }[]>((resolve, reject) =>
      {
        promisesList.forEach((currentPromise: Promise<any>, index: number) =>
        {
          currentPromise.then(
            (data) => // Success
            {
              result[index] = { data, isSuccess: true };
              if (promisesList.length <= ++count) { resolve(result); }
            },
            (data) => // Error
            {
              result[index] = { data, isSuccess: false };
              if (promisesList.length <= ++count) { resolve(result); }
            });
        });
      });
    }
    else
    {
      promise = Promise.resolve([]);
    }

    return promise;
  }

Explanation:
- Loop over the input promisesList and execute each Promise.
- No matter if the Promise resolved or rejected: save the Promise's result in a result array according to the index. Save also the resolve/reject status (isSuccess).
- Once all Promises completed, return one Promise with the result of all others.

Example of use:

const p1 = Promise.resolve("OK");
const p2 = Promise.reject(new Error(":-("));
const p3 = Promise.resolve(1000);

promiseExecuteAll([p1, p2, p3]).then((data) => {
  data.forEach(value => console.log(`${ value.isSuccess ? 'Resolve' : 'Reject' } >> ${ value.data }`));
});

/* Output: 
Resolve >> OK
Reject >> :-(
Resolve >> 1000
*/

You can use plain javascript, this will call your_func once, after 5 seconds:

setTimeout(function() { your_func(); }, 5000);

If your function has no parameters and no explicit receiver you can call directly setTimeout(func, 5000)

There is also a plugin I've used once. It has oneTime and everyTime methods.

• jQuery timers plugin

I discovered the best way to do it. Use Snap.svg to create the svg and then use the function toDataURL() that creates the graphics data to include as icon. Note that I use the SlidingMarker class for the marker that gives me nice movement of the marker. With Snap.svg you can create any kind of graphics and your map will look fantastic.

var s = Snap(100, 100);
s.text(50, 50, store.name);
// Use more graphics here.
var marker = new SlidingMarker({
  position: {lat: store.lat, lng: store.lng},
  map: $scope.map,
  label: store.name, // you do not need this
  title: store.name, // nor this
  duration: 2000,
  icon: s.toDataURL()
});

Don't live fanatically with the conventions that SUN have med up, do whats feel right to you and your team.

For example this is how eclipse do it, breaking the convention. Try adding implements Serializable and eclipse will ask to generate this line for you.

Update: There were special cases that was excluded didn't know that. I however withholds to do what you and your team seems fit.

Something like this:

$.getJSON("http://mywebsite.com/json/get.php?cid=15",
        function(data){
          $.each(data.products, function(i,product){
            content = '<p>' + product.product_title + '</p>';
            content += '<p>' + product.product_short_description + '</p>';
            content += '<img src="' + product.product_thumbnail_src + '"/>';
            content += '<br/>';
            $(content).appendTo("#product_list");
          });
        });

Would take a json object made from a PHP array returned with the key of products. e.g:

Array('products' => Array(0 => Array('product_title' => 'Product 1',
                                     'product_short_description' => 'Product 1 is a useful product',
                                     'product_thumbnail_src' => '/images/15/1.jpg'
                                    )
                          1 => Array('product_title' => 'Product 2',
                                     'product_short_description' => 'Product 2 is a not so useful product',
                                     'product_thumbnail_src' => '/images/15/2.jpg'
                                    )
                         )
     )

To reload the list you would simply do:

$("#product_list").empty();

And then call getJSON again with new parameters.

Since seangwright's solution (Edit 3) appears to be very useful, I also found it a pain to pack this feature into base component, and hint other project teammates to remember to call super() on ngOnDestroy to activate this feature.

This answer provide a way to set free from super call, and make "componentDestroyed$" a core of base component.

class BaseClass {
    protected componentDestroyed$: Subject<void> = new Subject<void>();
    constructor() {

        /// wrap the ngOnDestroy to be an Observable. and set free from calling super() on ngOnDestroy.
        let _$ = this.ngOnDestroy;
        this.ngOnDestroy = () => {
            this.componentDestroyed$.next();
            this.componentDestroyed$.complete();
            _$();
        }
    }

    /// placeholder of ngOnDestroy. no need to do super() call of extended class.
    ngOnDestroy() {}
}

And then you can use this feature freely for example:

@Component({
    selector: 'my-thing',
    templateUrl: './my-thing.component.html'
})
export class MyThingComponent extends BaseClass implements OnInit, OnDestroy {
    constructor(
        private myThingService: MyThingService,
    ) { super(); }

    ngOnInit() {
        this.myThingService.getThings()
            .takeUntil(this.componentDestroyed$)
            .subscribe(things => console.log(things));
    }

    /// optional. not a requirement to implement OnDestroy
    ngOnDestroy() {
        console.log('everything works as intended with or without super call');
    }

}

Using the "Developer Command Prompt for Visual Studio 20XX" instead of "cmd" will set the path for msbuild automatically without having to add it to your environment variables.

The datetime module will do all the work for you:

>>> import datetime
>>> a = datetime.datetime.now()
>>> # ...wait a while...
>>> b = datetime.datetime.now()
>>> print(b-a)
0:03:43.984000

If you don't want to display the microseconds, just use (as gnibbler suggested):

>>> a = datetime.datetime.now().replace(microsecond=0)
>>> b = datetime.datetime.now().replace(microsecond=0)
>>> print(b-a)
0:03:43

You can try _.isUndefined

<% if (!_.isUndefined(date)) { %><span class="date"><%= date %></span><% } %>

DateTime.Now.ToString("HH:mm:ss tt");

this gives it to you as a string.

file version < 5 : file -i -b /path/to/file
file version >=5 : file --mime-type -b /path/to/file

This may work:

Public Function getControls(Of T)() As List(Of T)
    Dim st As New Stack(Of Control)
    Dim ctl As Control
    Dim li As New List(Of T)

    st.Push(Me)

    While st.Count > 0
        ctl = st.Pop
        For Each c In ctl.Controls
            st.Push(CType(c, Control))
            If c.GetType Is GetType(T) Then
                li.Add(CType(c, T))
            End If
        Next
    End While

    Return li
End Function

I think the function to get all controls you are talking about is only available to WPF.

To upload files directly to Mongo DB you can make use of Grid FS. Although I will suggest you to upload the file anywhere in file system and put the image's url in the JSON object for every entry and then when you call the data for specific object you can call for the image using URL.

Tell me which backend technology are you using? I can give more suggestions based on that.

Date.parse() isn't a constructor, its a static method.

So, just use

var timeInMillis = Date.parse(s);

instead of

var timeInMillis = new Date.parse(s);

You can also use NumberUtil.isNumber(String str) from Apache Commons

Try \n\n , it will work! :)

There may be a text file in the above directory that contains the path you are trying to remove.

vim textfile //check and see what is in it when you are done looking type :q 
//:q just quits, no saves

If its the one you want to remove do this

rm textfile //remove it, delete it

Here is a link to a site that has more info on it, even though it illustrates 'adding' the path. However, you may gain some insight.

I've been having this same problem for over a day now - finally figured it out. Thanks to @Sameh for the hint.

Your service is probably working just fine. Testing POST messages using the address bar of a browser won't work. You need to use Fiddler to test a POST message.

Fiddler instructions... http://www.ehow.com/how_8788176_do-post-using-fiddler.html

This is to help anyone who comes here looking for a solution that wants a pure approach. I would recommend understanding this problem because it can happen in lots of different places not just with a JS Buffer object. By understanding why the problem exists and how to solve it you will improve your ability to solve other problems in the future since this one is so fundamental.

For those of us that have to deal with these problems in other languages it is quite natural to devise a solution, but there are people who may not realize how to abstract away the complexities and implement a generally efficient dynamic buffer. The code below may have potential to be optimized further.

I have left the read method unimplemented to keep the example small in size.

The realloc function in C (or any language dealing with intrinsic allocations) does not guarantee that the allocation will be expanded in size with out moving the existing data - although sometimes it is possible. Therefore most applications when needing to store a unknown amount of data will use a method like below and not constantly reallocate, unless the reallocation is very infrequent. This is essentially how most file systems handle writing data to a file. The file system simply allocates another node and keeps all the nodes linked together, and when you read from it the complexity is abstracted away so that the file/buffer appears to be a single contiguous buffer.

For those of you who wish to understand the difficulty in just simply providing a high performance dynamic buffer you only need to view the code below, and also do some research on memory heap algorithms and how the memory heap works for programs.

Most languages will provide a fixed size buffer for performance reasons, and then provide another version that is dynamic in size. Some language systems opt for a third-party system where they keep the core functionality minimal (core distribution) and encourage developers to create libraries to solve additional or higher level problems. This is why you may question why a language does not provide some functionality. This small core functionality allows costs to be reduced in maintaining and enhancing the language, however you end up having to write your own implementations or depending on a third-party.

    this.buffer_list.push(new Buffer(this.chunk_size));
};

    return obuf;
};

Reviving an old question because it seems to appear at the top of search results.

I wanted to retain transition effects while still being able to style the actionlink so I came up with this solution.

1. I wrapped the action link with a div that would contain the parent style:

<div class="parent-style-one">
      @Html.ActionLink("Homepage", "Home", "Home")
</div>

2. Next I create the CSS for the div, this will be the parent css and will be inherited by the child elements such as the action link.

  .parent-style-one {
     /* your styles here */
  }

3. Because all an action link is, is an element when broken down as html so you just need to target that element in your css selection:

  .parent-style-one a {
     text-decoration: none;
  }

4. For transition effects I did this:

  .parent-style-one a:hover {
        text-decoration: underline;
        -webkit-transition-duration: 1.1s; /* Safari */
        transition-duration: 1.1s;         
  }

This way I only target the child elements of the div in this case the action link and still be able to apply transition effects.

You can do pretty much the same as in JavaScript. Try this:

Console.WriteLine(mon + "." + da + "." + yer);

Or you can use WriteLine as if it were a string.Format statement by doing:

Console.WriteLine("{0}.{1}.{2}", mon, da, yer);

which is equivalent to:

string.Format("{0}.{1}.{2}", mon, da, yer);

The number of parameters can be infinite, just make sure you correctly index those numbers (starting at 0).

Check out javapassion, they have a number of courses that encompass web programming, and were free (until circumstances conspired to make the website need to support itself).

Even with the nominal fee, you get a lot for an entire year. It's a bargain compared to the amount of time you'll be investing.

The other options are to look to Oracle's online tutorials, they lack the glitz of Codeacademy, but are surprisingly good. I haven't read the one on web programming, that might be embedded in the Java EE tutorial(s), which is not tuned for a new beginner to Java.

The following will work with new versions of jQuery.

            $('#B').animate({left: 0});
        }
        else{
            $('#B').animate({left: 200});
        }

    });
});

If you have either ruby 1.9 or activesupport, you can do simply

@title = tokens[Title].try :tap, &:strip!

This is really cool, as it leverages the :try and the :tap method, which are the most powerful functional constructs in ruby, in my opinion.

An even cuter form, passing functions as symbols altogether:

@title = tokens[Title].send :try, :tap, &:strip!

If you need binary mode, you'll need to do it the hard way:

s = File.open(filename, 'rb') { |f| f.read }

If not, shorter and sweeter is:

s = IO.read(filename)

Here is one way to do it. It uses the ability of R to construct file paths based on the platform and hence will work on both Mac OS and Windows. Moreover, you don't need to convert your xls file to csv, as there are many R packages that will help you read xls directly (e.g. gdata package).

# get user's home directory
home = setwd(Sys.getenv("HOME"));

# construct path to file
fpath = file.path(home, "Desktop", "RTrial.xls");

# load gdata library to read xls files
library(gdata);

# read xls file
Rtrial = read.xls(fpath);

Let me know if this works.

I think it's a pretty strong assumption to assume that the object is a class. What if it's not a class? There's also the assumption that the object was not defined in the interpreter. What if it was defined in the interpreter? Also, what if the attributes were added dynamically? When some python objects have attributes added to their __dict__ after creation, pickle doesn't respect the addition of those attributes (i.e. it 'forgets' they were added -- because pickle serializes by reference to the object definition).

In all these cases, pickle and cPickle can fail you horribly.

If you are looking to save an object (arbitrarily created), where you have attributes (either added in the object definition, or afterward)… your best bet is to use dill, which can serialize almost anything in python.

We start with a class…

It works. The reason pickle fails, and dill doesn't, is that dill treats __main__ like a module (for the most part), and also can pickle class definitions instead of pickling by reference (like pickle does). The reason dill can pickle a lambda is that it gives it a name… then pickling magic can happen.

Actually, there's an easier way to save all these objects, especially if you have a lot of objects you've created. Just dump the whole python session, and come back to it later.

The only major drawback is that dill is not part of the python standard library. So if you can't install a python package on your server, then you can't use it.

However, if you are able to install python packages on your system, you can get the latest dill with git+https://github.com/uqfoundation/dill.git@master#egg=dill. And you can get the latest released version with pip install dill.

And now something completely different...

Instead of using css tricks don't forget about solutions as simple as html entities:

▲

Result:

▲

See: What are the HTML entities for up and down triangles?

In most cases they are essentially the same, but the second version saves memory because there is only one instance of the function instead of a separate function for each object.

A reason to use the first form is to access "private members". For example:

var A = function () {
    var private_var = ...;

    this.x = function () {
        return private_var;
    };

    this.setX = function (new_x) {
        private_var = new_x;
    };
};

Because of javascript's scoping rules, private_var is available to the function assigned to this.x, but not outside the object.

There are 3 ways to achieve this as shown below

Method 1:

var uName="abc";
var passwrd="pqr";

$.ajax({
    type: '{GET/POST}',
    url: '{urlpath}',
    headers: {
        "Authorization": "Basic " + btoa(uName+":"+passwrd);
    },
    success : function(data) {
      //Success block  
    },
   error: function (xhr,ajaxOptions,throwError){
    //Error block 
  },
});

Method 2:

var uName="abc";
var passwrd="pqr";

$.ajax({
    type: '{GET/POST}',
    url: '{urlpath}',
     beforeSend: function (xhr){ 
        xhr.setRequestHeader('Authorization', "Basic " + btoa(uName+":"+passwrd)); 
    },
    success : function(data) {
      //Success block 
   },
   error: function (xhr,ajaxOptions,throwError){
    //Error block 
  },
});

Method 3:

var uName="abc";
var passwrd="pqr";

$.ajax({
    type: '{GET/POST}',
    url: '{urlpath}',
    username:uName,
    password:passwrd, 
    success : function(data) {
    //Success block  
   },
    error: function (xhr,ajaxOptions,throwError){
    //Error block 
  },
});

I just emptied my session data then it worked again. Here is where you find the button:

Try using something like this:

<link rel="image_src" href="http://yoursite.com/graphics/yourimage.jpg" /link>`

Seems to work just fine on Firefox as long as you use a full path to your image.

Trouble is it get vertically offset downward for some reason. Image is 200 x 200 as recommended somewhere I read.

Combining @Ramnath and @Tommy's answers allowed me to find an approach that works in base R for one or more columns.

Basic usage:

> df = data.frame(
+   id=1:3, foo=c('a|b','b|c','c|d'), 
+   bar=c('p|q', 'r|s', 's|t'), stringsAsFactors=F)
> transform(df, test=do.call(rbind, strsplit(foo, '|', fixed=TRUE)), stringsAsFactors=F)
  id foo bar test.1 test.2
1  1 a|b p|q      a      b
2  2 b|c r|s      b      c
3  3 c|d s|t      c      d

Multiple columns:

> transform(df, lapply(list(foo,bar),
+ function(x)do.call(rbind, strsplit(x, '|', fixed=TRUE))), stringsAsFactors=F)
  id foo bar X1 X2 X1.1 X2.1
1  1 a|b p|q  a  b    p    q
2  2 b|c r|s  b  c    r    s
3  3 c|d s|t  c  d    s    t

Better naming of multiple split columns:

> transform(df, lapply({l<-list(foo,bar);names(l)=c('foo','bar');l}, 
+                          function(x)do.call(rbind, strsplit(x, '|', fixed=TRUE))), stringsAsFactors=F)
  id foo bar foo.1 foo.2 bar.1 bar.2
1  1 a|b p|q     a     b     p     q
2  2 b|c r|s     b     c     r     s
3  3 c|d s|t     c     d     s     t

The only correct way to run python cron jobs when using a virtualenv is to activate the environment and then execute the environment's python to run your code.

One way to do this is use virtualenv's activate_this in your python script, see: http://virtualenv.readthedocs.org/en/latest/userguide.html#using-virtualenv-without-bin-python

Another solution is echoing the complete command including activating the environment and piping it into /bin/bash. Consider this for your /etc/crontab:

***** root echo 'source /env/bin/activate; python /your/script' | /bin/bash

If you want to stick to grep:

grep -A1 'blah' logfile | grep -v "blah"

or alternatively with sed:

sed -n '/blah/{n;p;}' logfile

for /f "usebackq" %%d in (`"dir /ad/b/s | sort /R"`) do rd "%%d"

from: http://blogs.msdn.com/b/oldnewthing/archive/2008/04/17/8399914.aspx

Of course I'd test it first without deleting before I do that command. Also, here's a modded version from the comments that includes folders with spaces:

 for /f "usebackq delims=" %%d in (`"dir /ad/b/s | sort /R"`) do rd "%%d"

P.S. there are more comments in the blog post that might help you out so be sure to read those too before you try this out

mylist[c(5,7,9)] should do it.

You want the sublists returned as sublists of the result list; you don't use [[]] (or rather, the function is [[) for that -- as Dason mentions in comments, [[ grabs the element.

2020 | SWIFT 5.1:

From STRING to URL:

let url = URL(fileURLWithPath: "//Users/Me/Desktop/Doc.txt")

From URL to STRING:

let a = String(describing: url)       // "file:////Users/Me/Desktop/Doc.txt"
let b = "\(url)"                      // "file:////Users/Me/Desktop/Doc.txt"
let c = url.absoluteString            // "file:////Users/Me/Desktop/Doc.txt"
let d = url.path                      // "/Users/Me/Desktop/Doc.txt" 

BUT value of d will be invisible due to debug process, so...

THE BEST SOLUTION:

let e = "\(url.path)"                 // "/Users/Me/Desktop/Doc.txt"

you can call the button_click event by passing..

private void SubGraphButton_Click(object sender, RoutedEventArgs args)
{
}

private void ChildNode_Click(object sender, RoutedEventArgs args)
{
   SubGraphButton_Click(sender, args);
}

Also without passing..

private void SubGraphButton_Click(object sender, EventArgs args)
{
}

private void Some_Method() //this method is called
{
   SubGraphButton_Click(new object(), new EventArgs());
}

give your boxes the class foo (or whatever) and add the css

.foo{
    float: left;
}

The hashcode will be calculated based on the ASCII values of the characters in the String.

This is the implementation in the String Class is as follows

public int hashCode() {
    int h = hash;
    if (h == 0 && value.length > 0) {
        hash = h = isLatin1() ? StringLatin1.hashCode(value)
                              : StringUTF16.hashCode(value);
    }
    return h;
}

Collisions in hashcode are unavoidable. For example, the strings "Ea" and "FB" give the same hashcode as 2236

Collection (so ArrayList also) have:

col.retainAll(otherCol) // for intersection
col.addAll(otherCol) // for union

Use a List implementation if you accept repetitions, a Set implementation if you don't:

Collection<String> col1 = new ArrayList<String>(); // {a, b, c}
// Collection<String> col1 = new TreeSet<String>();
col1.add("a");
col1.add("b");
col1.add("c");

Collection<String> col2 = new ArrayList<String>(); // {b, c, d, e}
// Collection<String> col2 = new TreeSet<String>();
col2.add("b");
col2.add("c");
col2.add("d");
col2.add("e");

col1.addAll(col2);
System.out.println(col1); 
//output for ArrayList: [a, b, c, b, c, d, e]
//output for TreeSet: [a, b, c, d, e]

You can do in different ways.

str1 = "Hello"
str2 = "World"
str_list = ['Hello', 'World']
str_dict = {'str1': 'Hello', 'str2': 'World'}

# Concatenating With the + Operator
print(str1 + ' ' + str2)  # Hello World

# String Formatting with the % Operator
print("%s %s" % (str1, str2))  # Hello World

# String Formatting with the { } Operators with str.format()
print("{}{}".format(str1, str2))  # Hello World
print("{0}{1}".format(str1, str2))  # Hello World
print("{str1} {str2}".format(str1=str_dict['str1'], str2=str_dict['str2']))  # Hello World
print("{str1} {str2}".format(**str_dict))  # Hello World

# Going From a List to a String in Python With .join()
print(' '.join(str_list))  # Hello World

# Python f'strings --> 3.6 onwards
print(f"{str1} {str2}")  # Hello World

I created this little summary through following articles.

• Python 3's f-Strings: An Improved String Formatting Syntax (Guide) (Speed test also included)
• Formatted string literals
• String Concatenation and Formatting
• Splitting, Concatenating, and Joining Strings in Python

With the option FollowSymLinks enabled:

$ rg "FollowSymLinks" /etc/httpd/
/etc/httpd/conf/httpd.conf
269:    Options Indexes FollowSymLinks

you need all the directories in symlink to be executable by the user httpd is using.

so for this general use case:

cd /path/to/your/web
sudo ln -s $PWD /srv/http/

You can check owner an permissions with namei:

$ namei -m /srv/http/web
f: /srv/http/web
 drwxr-xr-x /
 drwxr-xr-x srv
 drwxr-xr-x http
 lrwxrwxrwx web -> /path/to/your/web
   drwxr-xr-x /
   drwxr-xr-x path
   drwx------ to
   drwxr-xr-x your
   drwxr-xr-x web

In my case to directory was only executable for my user:

Enable execution by others solve it:

chmod o+x /path/to

See the non executable directory could be different, or you need to affect groups instead others, that depends on your case.

I think one of the main problems which occur is that the virtualenv might not be usable by other people. Reason is that it always uses absolute paths. So if you virtualenv was for example in /home/lyle/myenv/ it will assume the same for all other people using this repository (it must be exactly the same absolute path). You can't presume people using the same directory structure as you.

Better practice is that everybody is setting up their own environment (be it with or without virtualenv) and installing libraries there. That also makes you code more usable over different platforms (Linux/Windows/Mac), also because virtualenv is installed different in each of them.

jsondata = '{"0001":{"FirstName":"John","LastName":"Mark","MiddleName":"Lewis","username":"johnlewis2","password":"2910"}}'

jdata = json.loads(jsondata)

print df.T

This should look like this:.

Check this: How to maximize a plt.show() window using Python

The command is different depending on which backend you use. I find that this is the best way to make sure the saved pictures have the same scaling as what I view on my screen.

Since I use Canopy with the QT backend:

pylab.get_current_fig_manager().window.showMaximized()

I then call savefig() as required with an increased DPI per silvado's answer.

Custom Comparator should help

Collections.sort(list, new Comparator<String>() {
    @Override
    public int compare(String s1, String s2) {
        return s1.compareToIgnoreCase(s2);
    }
});

Or if you are using Java 8:

list.sort(String::compareToIgnoreCase);

Starting another dispatch before your reducer is finished is an anti-pattern, because the state you received at the beginning of your reducer will not be the current application state anymore when your reducer finishes. But scheduling another dispatch from within a reducer is NOT an anti-pattern. In fact, that is what the Elm language does, and as you know Redux is an attempt to bring the Elm architecture to JavaScript.

Here is a middleware that will add the property asyncDispatch to all of your actions. When your reducer has finished and returned the new application state, asyncDispatch will trigger store.dispatch with whatever action you give to it.

// This middleware will just add the property "async dispatch" to all actions
const asyncDispatchMiddleware = store => next => action => {
  let syncActivityFinished = false;
  let actionQueue = [];

  function flushQueue() {
    actionQueue.forEach(a => store.dispatch(a)); // flush queue
    actionQueue = [];
  }

  function asyncDispatch(asyncAction) {
    actionQueue = actionQueue.concat([asyncAction]);

    if (syncActivityFinished) {
      flushQueue();
    }
  }

  const actionWithAsyncDispatch =
    Object.assign({}, action, { asyncDispatch });

  const res = next(actionWithAsyncDispatch);

  syncActivityFinished = true;
  flushQueue();

  return res;
};

Now your reducer can do this:

function reducer(state, action) {
  switch (action.type) {
    case "fetch-start":
      fetch('wwww.example.com')
        .then(r => r.json())
        .then(r => action.asyncDispatch({ type: "fetch-response", value: r }))
      return state;

    case "fetch-response":
      return Object.assign({}, state, { whatever: action.value });;
  }
}

To piggyback on rkj's answer, to avoid endless prompts (and force the command recursively), enter the following into the command line, within the project folder:

$ rm -rf .git

Or to delete .gitignore and .gitmodules if any (via @aragaer):

$ rm -rf .git*

Then from the same ex-repository folder, to see if hidden folder .git is still there:

$ ls -lah

If it's not, then congratulations, you've deleted your local git repo, but not a remote one if you had it. You can delete GitHub repo on their site (github.com).

To view hidden folders in Finder (Mac OS X) execute these two commands in your terminal window:

defaults write com.apple.finder AppleShowAllFiles TRUE
killall Finder

Windows has the facility to prevent windows from stealing focus; instead it flashes the taskbar icon. In XP it's on by default (the only place I've seen to change it is using TweakUI, but there is a registry setting somewhere). In Vista they may have changed the default and/or exposed it as a user accessible setting with the out-of-the-box UI.

Preventing windows from forcing themselves to the front and taking focus is a feature since Windows 2K (and I, for one, am thankful for it).

That said, I have a little Java app I use to remind me to record my activities while working, and it makes itself the active window every 30 minutes (configurable, of course). It always works consistently under Windows XP and never flashes the title bar window. It uses the following code, called in the UI thread as a result of a timer event firing:

if(getState()!=Frame.NORMAL) { setState(Frame.NORMAL); }
toFront();
repaint();

(the first line restores if minimized... actually it would restore it if maximized too, but I never have it so).

While I usually have this app minimized, quite often it's simply behind my text editor. And, like I said, it always works.

I do have an idea on what your problem could be - perhaps you have a race condition with the setVisible() call. toFront() may not be valid unless the window is actually displayed when it is called; I have had this problem with requestFocus() before. You may need to put the toFront() call in a UI listener on a window activated event.

2014-09-07: At some point in time the above code stopped working, perhaps at Java 6 or 7. After some investigation and experimentation I had to update the code to override the window's toFront method do this (in conjunction with modified code from what is above):

setVisible(true);
toFront();
requestFocus();
repaint();

...

public @Override void toFront() {
    int sta = super.getExtendedState() & ~JFrame.ICONIFIED & JFrame.NORMAL;

    super.setExtendedState(sta);
    super.setAlwaysOnTop(true);
    super.toFront();
    super.requestFocus();
    super.setAlwaysOnTop(false);
}

As of Java 8_20, this code seems to be working fine.

The problem with your original code was you are calling scrollticker() by passing a string to setInterval, where you should just pass the function name and treat it as a variable:

lefttime = setInterval(scrollticker, 50);

instead of

lefttime = setInterval("scrollticker()", 50);

TcpClient c;

//I want to check here if port is free.
c = new TcpClient(ip, port);

...how can I first check if a certain port is free on my machine?

I mean that it is not in use by any other application. If an application is using a port others can't use it until it becomes free. – Ali

You have misunderstood what's happening here.

TcpClient(...) parameters are of server ip and server port you wish to connect to.

The TcpClient selects a transient local port from the available pool to communicate to the server. There's no need to check for the availability of the local port as it is automatically handled by the winsock layer.

In case you can't connect to the server using the above code fragment, the problem could be one or more of several. (i.e. server ip and/or port is wrong, remote server not available, etc..)

To call a function inside a same controller in any laravel version follow as bellow

use the android:background attribute in your xml. Easiest way if you want to apply it to a whole activity is to put it in the root of your layout. So if you have a RelativeLayout as the start of your xml, put it in here:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/rootRL"
    android:orientation="vertical"

When You get your new SSL cert from Comodo (by mail) they have a zip file attached. You need to unzip the zip-file and open the following files in a text editor like notepad:

AddTrustExternalCARoot.crt
COMODORSAAddTrustCA.crt
COMODORSADomainValidationSecureServerCA.crt

Then copy the text of each ".crt" file and paste the texts above eachother in the "Certificate Authority Bundle (optional)" field.

After that just add the SSL cert as usual in the "Certificate" field and click at "Autofil by Certificate" button and hit "Install".

 $ git commit --allow-empty -m "Trigger Build"

My recipe to fix it:

1. DID NOT WORK >> Set as system environment variable: I had set the environment variable in my mac bash_profile, however, Tomcat did not see that variable.

2. DID NOT WORK >> setenv.sh: Apache's recommendation was to have user-defined environment variables in setenv.sh file and I did that.

3. THIS WORKED!! >> After a little research into Tomcat startup scripts, I found that environment variables set using setenv.sh are lost during the startup. So I had to edit my catalina.sh against the recommendation of Apache and that did the trick.

Add your -DUSER_DEFINED variable in the run command in catalina.sh.

eval exec "\"$_RUNJAVA\"" "\"$LOGGING_CONFIG\"" $LOGGING_MANAGER $JAVA_OPTS $CATALINA_OPTS \
  -classpath "\"$CLASSPATH\"" \
  -Djava.security.manager \
  -Djava.security.policy=="\"$CATALINA_BASE/conf/catalina.policy\"" \
  -Dcatalina.base="\"$CATALINA_BASE\"" \
  -Dcatalina.home="\"$CATALINA_HOME\"" \
  -Djava.io.tmpdir="\"$CATALINA_TMPDIR\"" \
  -DUSER_DEFINED="$USER_DEFINED" \
  org.apache.catalina.startup.Bootstrap "$@" start

P.S: This problem could have been local to my computer. Others would have different problems. Adding my answer to this post just in case anyone is still facing issues with Tomcat not seeing the environment vars after trying out all recommended approaches.

Try:

zero=0;

if [[ $depth -eq $zero ]]; then
  echo "false";
  exit;
fi

Not sure what you are really after but if you want to print exactly what you have you can do:

Option 1

print(df['Item'].to_csv(index=False))

Sweet
Candy
Chocolate

Option 2

for v in df['Item']:
    print(v)

Sweet
Candy
Chocolate

A gc-friendly piece of code:

public static<X> X[] arrayOfNotNull(X[] array) {
    for (int p=0, N=array.length; p<N; ++p) {
        if (array[p] == null) {
            int m=p; for (int i=p+1; i<N; ++i) if (array[i]!=null) ++m;
            X[] res = Arrays.copyOf(array, m);
            for (int i=p+1; i<N; ++i) if (array[i]!=null) res[p++] = array[i];
            return res;
        }
    }
    return array;
}

It returns the original array if it contains no nulls. It does not modify the original array.

If you've already committed a bunch of unwanted files, you can unstage them and tell git to mark them as deleted (without actually deleting them) with

git rm --cached -r .

--cached tells it to remove the paths from staging and the index without removing the files themselves and -r operates on directories recursively. You can then git add any files that you want to keep tracking.

In my case, I replaced the src taq using:

   $('#gmap_canvas').attr('src', newSrc);

For HTTP things, the current choice should be: Requests- HTTP for Humans

res = request.GET['paymentid'] will raise a KeyError if paymentid is not in the GET data.

Your sample php code checks to see if paymentid is in the POST data, and sets $payID to '' otherwise:

$payID = isset($_POST['paymentid']) ? $_POST['paymentid'] : ''

The equivalent in python is to use the get() method with a default argument:

payment_id = request.POST.get('payment_id', '')

while debugging, this is what I see in the response.GET: <QueryDict: {}>, request.POST: <QueryDict: {}>

It looks as if the problem is not accessing the POST data, but that there is no POST data. How are you are debugging? Are you using your browser, or is it the payment gateway accessing your page? It would be helpful if you shared your view.

Once you are managing to submit some post data to your page, it shouldn't be too tricky to convert the sample php to python.

I noticed that the encoding of the .gitignore was having an effect--if the file was Unicode, it was ignored, if it was ASCII, it wasn't.

Process:

1. Verify status: PS> git status
2. Create a function to Get-FileEncoding
3. Test .gitignore's encoding: PS> Get-FileEncoding .gitignore
4. Change the encoding to ASCII: PS> Set-Content .gitignore -Encoding Ascii -Value (Get-Content .gitignore)
5. Confirm: PS> git status

The query to get the nth highest record is as follows:

SELECT 
    *
FROM
    (SELECT 
        *
    FROM
        table_name
    ORDER BY column_name ASC
    LIMIT N) AS tbl
ORDER BY column_name DESC
LIMIT 1;

It's simple and easy to understand

Since you are conditionally indexing df$est, you also need to conditionally index the replacement vector df$a:

index <- df$b == 0
df$est[index] <- (df$a[index] - 5)/2.533 

Of course, the variable index is just temporary, and I use it to make the code a bit more readible. You can write it in one step:

df$est[df$b == 0] <- (df$a[df$b == 0] - 5)/2.533 

For even better readibility, you can use within:

df <- within(df, est[b==0] <- (a[b==0]-5)/2.533)

The results, regardless of which method you choose:

df
          a b      est
1  11.77000 2 0.000000
2  10.90000 3 0.000000
3  10.32000 2 0.000000
4  10.96000 0 2.352941
5   9.90600 0 1.936834
6  10.70000 0 2.250296
7  11.43000 1 0.000000
8  11.41000 2 0.000000
9  10.48512 4 0.000000
10 11.19000 0 2.443743

As others have pointed out, an alternative solution in your example is to use ifelse.

IF you want to derive usg Boolean true False need to add "[]" around value

<form [formGroup]="form">
  <input type="radio" [value]=true formControlName="gender" >Male
  <input type="radio" [value]=false formControlName="gender">Female
</form>

Alliteratively you can try placing a Label control and placing it on top of the progress bar control. Then you can set whatever the text you want to the label. I haven't done this my self. If it works it should be a simpler solution than overriding onpaint.

• native is a keyword in java, it indicates platform dependent.
• native methods are acts as interface between Java(JNI) and other programming languages.

You need to bind the modal hide call to the onclick event.

Assuming you are using jQuery you can do that with:

$('#closemodal').click(function() {
    $('#modalwindow').modal('hide');
});

Also make sure the click event is bound after the document has finished loading:

$(function() {
   // Place the above code inside this block
});
enter code here

Along the lines of ggovan's answer, I do this as follows:

/**
 * Provides various high-order functions.
 */
public final class F {
    /**
     * When the returned {@code Function} is passed as an argument to
     * {@link Stream#flatMap}, the result is a stream of instances of
     * {@code cls}.
     */
    public static <E> Function<Object, Stream<E>> instancesOf(Class<E> cls) {
        return o -> cls.isInstance(o)
                ? Stream.of(cls.cast(o))
                : Stream.empty();
    }
}

Using this helper function:

Stream.of(objects).flatMap(F.instancesOf(Client.class))
        .map(Client::getId)
        .forEach(System.out::println);

I have been trying to do the same. Came up with another simpler solution after working with a colleague. I have a watch set up on $location.path(). That does the trick. I am just starting to learn AngularJS and find this to be more cleaner and readable.

$scope.$watch(function() { return $location.path(); }, function(newValue, oldValue){  
    if ($scope.loggedIn == false && newValue != '/login'){  
            $location.path('/login');  
    }  
});

It's as simple as:

num1 = num2 = 5;

When using an object property instead of variable, it is interesting to know that the get accessor of the intermediate value is not called. Only the set accessor is invoked for all property accessed in the assignation sequence.

Take for example a class that write to the console everytime the get and set accessor are invoked.

static void Main(string[] args)
{
    var accessorSource = new AccessorTest(5);
    var accessor1 = new AccessorTest();
    var accessor2 = new AccessorTest();

    accessor1.Value = accessor2.Value = accessorSource.Value;

    Console.ReadLine();
}

public class AccessorTest
{
    public AccessorTest(int value = default(int))
    {
        _Value = value;
    }

    private int _Value;

    public int Value
    {
        get
        {
            Console.WriteLine("AccessorTest.Value.get {0}", _Value);
            return _Value;
        }
        set
        {
            Console.WriteLine("AccessorTest.Value.set {0}", value);
            _Value = value;
        }
    }
}

This will output

AccessorTest.Value.get 5
AccessorTest.Value.set 5
AccessorTest.Value.set 5

Meaning that the compiler will assign the value to all properties and it will not re-read the value every time it is assigned.

At the extreme ranges, an unsigned int can become larger than an int.
Therefore, the compiler generates a warning. If you are sure that this is not a problem, feel free to cast the types to the same type so the warning disappears (use C++ cast so that they are easy to spot).

Alternatively, make the variables the same type to stop the compiler from complaining.
I mean, is it possible to have a negative padding? If so then keep it as an int. Otherwise you should probably use unsigned int and let the stream catch the situations where the user types in a negative number.

1. This occurs when you have a (Primary key) column that is not set to Is Identity to true in SQL and you don't pass explicit value thereof during insert. It will take the first row, then you wont be able to insert the second row, the error will pop up. This can be corrected by adding this line of code [DatabaseGenerated(DatabaseGeneratedOption.Identity)] in your PrimaryKey column and make sure its set to a data type int. If the column is the primary key and is set to IsIDentity to true in SQL there is no need for this line of code [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
2. this also occurs when u have a column that is not the primary key, in SQL that is set to Is Identity to true, and in your EF you did not add this line of code [DatabaseGenerated(DatabaseGeneratedOption.Identity)]

Script for backward-compatibility: https://github.com/douglascrockford/JSON-js/blob/master/json2.js

And call:

var myJsonString = JSON.stringify(yourArray);

Note: The JSON object is now part of most modern web browsers (IE 8 & above). See caniuse for full listing. Credit goes to: @Spudley for his comment below

This article discusses various approaches. Here are the 2 key approaches mentioned in the article:

JEXL from Apache

Allows for scripts that include references to java objects.

// Create or retrieve a JexlEngine
JexlEngine jexl = new JexlEngine();
// Create an expression object
String jexlExp = "foo.innerFoo.bar()";
Expression e = jexl.createExpression( jexlExp );
 
// Create a context and add data
JexlContext jctx = new MapContext();
jctx.set("foo", new Foo() );
 
// Now evaluate the expression, getting the result
Object o = e.evaluate(jctx);

Use the javascript engine embedded in the JDK:

private static void jsEvalWithVariable()
{
    List<String> namesList = new ArrayList<String>();
    namesList.add("Jill");
    namesList.add("Bob");
    namesList.add("Laureen");
    namesList.add("Ed");
 
    ScriptEngineManager mgr = new ScriptEngineManager();
    ScriptEngine jsEngine = mgr.getEngineByName("JavaScript");
 
    jsEngine.put("namesListKey", namesList);
    System.out.println("Executing in script environment...");
    try
    {
      jsEngine.eval("var x;" +
                    "var names = namesListKey.toArray();" +
                    "for(x in names) {" +
                    "  println(names[x]);" +
                    "}" +
                    "namesListKey.add(\"Dana\");");
    }
    catch (ScriptException ex)
    {
        ex.printStackTrace();
    }
}

You need to use Integer.parseInt(String)

private void jTextField2MouseClicked(java.awt.event.MouseEvent evt) {
        if(evt.getSource()==jTextField2){
            int jml = Integer.parseInt(jTextField3.getText());
            jTextField1.setText(numberToWord(jml));

        }
    }

This should work. But I have same problems on an Android phone.

<input type="number" /> <input type="tel" />

I found out, that if I didn't include the jquerymobile-framework, the keypad showed correctly on the two types of fields.

But I havn't found a solution to solve that problem, if you really need to use jquerymobile.

UPDATE: I found out, that if the form-tag is stored out of the

<div data-role="page"> 

The number keypad isn't shown. This must be a bug...

here is the solution for similar problem which i was facing while extracting name from user profile facebook json object

$uname=json_encode($userprof);
$uname=json_decode($uname);
echo "Welcome " . $uname -> name  ;

Yes that is correct. "Boolean variables only have two possible values: true (1) and false (0)." cpp tutorial on boolean values

import yaml

data = dict(
    A = 'a',
    B = dict(
        C = 'c',
        D = 'd',
        E = 'e',
    )
)

with open('data.yml', 'w') as outfile:
    yaml.dump(data, outfile, default_flow_style=False)

The default_flow_style=False parameter is necessary to produce the format you want (flow style), otherwise for nested collections it produces block style:

A: a
B: {C: c, D: d, E: e}

%d--> for int

%u--> for unsigned int

%ld--> for long int or long

%lu--> for unsigned long int or long unsigned int or unsigned long

%lld--> for long long int or long long

%llu--> for unsigned long long int or unsigned long long

I'm guessing you have a NUL byte in input.csv. You can test that with

if '\0' in open('input.csv').read():
    print "you have null bytes in your input file"
else:
    print "you don't"

if you do,

reader = csv.reader(x.replace('\0', '') for x in mycsv)

may get you around that. Or it may indicate you have utf16 or something 'interesting' in the .csv file.

Add this line to your AndroidManifest.xml:

<activity android:name=".OrderScreen" /> 

By using Image.alpha_composite, the solution by Yuji 'Tomita' Tomita become simpler. This code can avoid a tuple index out of range error if png has no alpha channel.

from PIL import Image

png = Image.open(img_path).convert('RGBA')
background = Image.new('RGBA', png.size, (255,255,255))

alpha_composite = Image.alpha_composite(background, png)
alpha_composite.save('foo.jpg', 'JPEG', quality=80)

A serval times of fighting, I finally solved the problem.
(Note: I use standard AES as symmetric algorithm. This answer may not suitable for everyone.)

1. Change the algorithm class. Replace the RijndaelManaged class to AESManaged one.
2. Do not explicit set the KeySize of algorithm class, left them default.
   (This is the very important step. I think there is a bug in KeySize property.)

Here is a list you want to check which argument you might have missed:

• Key
  (byte array, length must be exactly one of 16, 24, 32 byte for different key size.)
• IV
  (byte array, 16 bytes)
• CipherMode
  (One of CBC, CFB, CTS, ECB, OFB)
• PaddingMode
  (One of ANSIX923, ISO10126, None, PKCS7, Zeros)

WARNING: It should be noted that this solution will block the calling thread.

If you want to process exceptions thrown by the task, then it is generally better to use Callable rather than Runnable.

Callable.call() is permitted to throw checked exceptions, and these get propagated back to the calling thread:

Callable task = ...
Future future = executor.submit(task);
try {
   future.get();
} catch (ExecutionException ex) {
   ex.getCause().printStackTrace();
}

If Callable.call() throws an exception, this will be wrapped in an ExecutionException and thrown by Future.get().

This is likely to be much preferable to subclassing ThreadPoolExecutor. It also gives you the opportunity to re-submit the task if the exception is a recoverable one.

The attribute packed means that the compiler will not add padding between fields of the struct. Padding is usually used to make fields aligned to their natural size, because some architectures impose penalties for unaligned access or don't allow it at all.

aligned(4) means that the struct should be aligned to an address that is divisible by 4.

A set comparison work:

len(set(the_list)) == 1

Using set removes all duplicate elements.

You have to create two triggers, but you can move the common code into a procedure and have them both call the procedure.

Try:

task.AsyncResult(task.request.id).state

this will provide the Celery Task status. If Celery Task is already is under FAILURE state it will throw an Exception:

raised unexpected: KeyError('exc_type',)

If you want decompress without software better use this code. Other code with pdf files sends error on manually decompress

byte[] buffer = new byte[1024];     
    try
    {   
        FileOutputStream fos = new FileOutputStream("123.zip");
        ZipOutputStream zos = new ZipOutputStream(fos);
        ZipEntry ze= new ZipEntry("file.pdf");
        zos.putNextEntry(ze);
        FileInputStream in = new FileInputStream("file.pdf");
        int len;
        while ((len = in.read(buffer)) > 0) 
        {
            zos.write(buffer, 0, len);
        }
        in.close();
        zos.closeEntry();
        zos.close();
    }
    catch(IOException ex)
    {
       ex.printStackTrace();
    }

In case you need the [] syntax, useful for "edit forms" when you need to pass parameters like id with the route, you would do something like:

[routerLink]="['edit', business._id]"

As for an "about page" with no parameters like yours,

[routerLink]="/about"

or

[routerLink]=['about']

will do the trick.

You can use this, pithy. :D

TextBox1.Focus();    
TextBox1.Select(0, TextBox1.Text.Length);

You can also use logical tests

x <- data.frame(a = c(0,1,2,NA), b = c(0,NA,1,2), c = c(NA, 0, 1, 2)) 
x
x$a <- replace(x$a, is.na(x$a), 0)
x
x$b <- replace(x$b, x$b==2, 333)

In a decorator method, you can list arguments of the original method in this way:

import inspect, itertools 

def my_decorator():

        def decorator(f):

            def wrapper(*args, **kwargs):

                # if you want arguments names as a list:
                args_name = inspect.getargspec(f)[0]
                print(args_name)

                # if you want names and values as a dictionary:
                args_dict = dict(itertools.izip(args_name, args))
                print(args_dict)

                # if you want values as a list:
                args_values = args_dict.values()
                print(args_values)

If the **kwargs are important for you, then it will be a bit complicated:

        def wrapper(*args, **kwargs):

            args_name = list(OrderedDict.fromkeys(inspect.getargspec(f)[0] + kwargs.keys()))
            args_dict = OrderedDict(list(itertools.izip(args_name, args)) + list(kwargs.iteritems()))
            args_values = args_dict.values()

Example:

@my_decorator()
def my_function(x, y, z=3):
    pass


my_function(1, y=2, z=3, w=0)
# prints:
# ['x', 'y', 'z', 'w']
# {'y': 2, 'x': 1, 'z': 3, 'w': 0}
# [1, 2, 3, 0]

1. checked
2. checked=""

3. checked="checked"

   are equivalent;

according to spec checkbox '----? checked = "checked" or "" (empty string) or empty Specifies that the element represents a selected control.---'

It should be text-align, not align

https://developer.mozilla.org/en/CSS/text-align

I struggled with this, too. My specific setup is: Your host.ini (with the modern names):

[test3]
test3-1 ansible_host=abc.def.ghi.pqr ansible_port=1212
test3-2 ansible_host=abc.def.ghi.stu ansible_port=1212

plus a play fill_file.yml

---
- remote_user: ec2-user
  hosts: test3
  tasks:
   - name: fill file
     template:
       src: file.j2
       dest: filled_file.txt

plus a template file.j2 , like

{% for host in groups['test3'] %}
   {{ hostvars[host].ansible_host }}
{% endfor %}

This worked for me, the result is

abc.def.ghi.pqr
abc.def.ghi.stu

I have to admit it's ansible 2.7, not 2.1. The template is a variation of an example in https://docs.ansible.com/ansible/latest/user_guide/playbooks_variables.html.

The accepted answer didn't work in my setup. With a template

{{ hostvars['test3'].ansible_host }}

my play fails with "AnsibleUndefinedVariable: \"hostvars['test3']\" is undefined" .

Remark: I tried some variations, but failed, occasionally with "ansible.vars.hostvars.HostVars object has no element "; Some of this might be explained by what they say. in https://github.com/ansible/ansible/issues/13343#issuecomment-160992631

hostvars emulates a dictionary [...]. hostvars is also lazily loaded

How about:

if(str!= null && str.length() != 0 )

I won't address the READ UNCOMMITTED argument, just your original question.

Yes, you need WITH(NOLOCK) on each table of the join. No, your queries are not the same.

Try this exercise. Begin a transaction and insert a row into table1 and table2. Don't commit or rollback the transaction yet. At this point your first query will return successfully and include the uncommitted rows; your second query won't return because table2 doesn't have the WITH(NOLOCK) hint on it.

You can increase security in authentication process by using JWT (JSON Web Tokens) and SSL/HTTPS.

The Basic Auth / Session ID can be stolen via:

• MITM attack (Man-In-The-Middle) - without SSL/HTTPS
• An intruder gaining access to a user's computer
• XSS

By using JWT you're encrypting the user's authentication details and storing in the client, and sending it along with every request to the API, where the server/API validates the token. It can't be decrypted/read without the private key (which the server/API stores secretly) Read update.

The new (more secure) flow would be:

Login

• User logs in and sends login credentials to API (over SSL/HTTPS)
• API receives login credentials
• If valid:
  • Register a new session in the database Read update
  • Encrypt User ID, Session ID, IP address, timestamp, etc. in a JWT with a private key.
• API sends the JWT token back to the client (over SSL/HTTPS)
• Client receives the JWT token and stores in localStorage/cookie

Every request to API

• User sends a HTTP request to API (over SSL/HTTPS) with the stored JWT token in the HTTP header
• API reads HTTP header and decrypts JWT token with its private key
• API validates the JWT token, matches the IP address from the HTTP request with the one in the JWT token and checks if session has expired
• If valid:
  • Return response with requested content
• If invalid:
  • Throw exception (403 / 401)
  • Flag intrusion in the system
  • Send a warning email to the user.

Updated 30.07.15:

JWT payload/claims can actually be read without the private key (secret) and it's not secure to store it in localStorage. I'm sorry about these false statements. However they seem to be working on a JWE standard (JSON Web Encryption).

I implemented this by storing claims (userID, exp) in a JWT, signed it with a private key (secret) the API/backend only knows about and stored it as a secure HttpOnly cookie on the client. That way it cannot be read via XSS and cannot be manipulated, otherwise the JWT fails signature verification. Also by using a secure HttpOnly cookie, you're making sure that the cookie is sent only via HTTP requests (not accessible to script) and only sent via secure connection (HTTPS).

Updated 17.07.16:

JWTs are by nature stateless. That means they invalidate/expire themselves. By adding the SessionID in the token's claims you're making it stateful, because its validity doesn't now only depend on signature verification and expiry date, it also depends on the session state on the server. However the upside is you can invalidate tokens/sessions easily, which you couldn't before with stateless JWTs.

tl;dr

Another option is the Objects.equals utility method.

Objects.equals( thisEnum , thatEnum )

Objects.equals for null-safety

equals operator == instead of .equals()

Which operator is the one I should be using?

A third option is the static equals method found on the Objects utility class added to Java 7 and later.

Example

Here’s an example using the Month enum.

boolean areEqual = Objects.equals( Month.FEBRUARY , Month.JUNE ) ;  // Returns `false`.

I find a couple benefits to this method:

• Null-safety
  • Both null ? true
  • Either null ? false
  • No risk of throwing NullPointerException
• Compact, readable

How it works

What is the logic used by Objects.equals?

See for yourself, from the Java 10 source code of OpenJDK:

return (a == b) || (a != null && a.equals(b));

If you want case-insensitive comparison, use lower or upper:

if name.lower() == "jesse":

It depends on the type of chip you are using, but nowerdays most chips you can write. It also depends on how much power you give your RFID device. To read you dont need allot of power and very little line of sight. To right you need them full insight and longer insight

For what it's worth, here are two pointless ways of doing it:

scala> case class Foo(bar: Int)
defined class Foo

scala> import scalaz._, Scalaz._
import scalaz._
import Scalaz._

scala> val c = Vector(Foo(9), Foo(11))
c: scala.collection.immutable.Vector[Foo] = Vector(Foo(9), Foo(11))

scala> c.map(((_: Foo).bar) &&& identity).toMap
res30: scala.collection.immutable.Map[Int,Foo] = Map(9 -> Foo(9), 11 -> Foo(11))

scala> c.map(((_: Foo).bar) >>= (Pair.apply[Int, Foo] _).curried).toMap
res31: scala.collection.immutable.Map[Int,Foo] = Map(9 -> Foo(9), 11 -> Foo(11))

Just in case anyone is in my boat where none of these answers worked exactly, here's what I did.

Perhaps our in house Bitbucket server is set up a little differently than most, but here's the URL that I'd normally go to just to view the files in the master branch:

https://<BITBUCKET_URL>/projects/<PROJECT_GROUP>/repos/<REPO_NAME>/browse

If I select a different branch than master from the drop down menu, I get this:

https://<BITBUCKET_URL>/projects/<PROJECT_GROUP>/repos/<REPO_NAME>/browse?at=refs%2Fheads%2F<BRANCH_NAME>

So I tried doing this and it worked:

https://<BITBUCKET_URL>/projects/<PROJECT_GROUP>/repos/<REPO_NAME>/browse?at=<COMMIT_ID>

Now I can browse the whole repo as it was at the time of that commit.

You can use DistinctBy() for getting Distinct records by an object property. Just add the following statement before using it:

using Microsoft.Ajax.Utilities;

and then use it like following:

var listToReturn = responseList.DistinctBy(x => x.Index).ToList();

where 'Index' is the property on which i want the data to be distinct.

You could also use the RANK function

=RANK(C2,$C$2:$C$7,0)

It would return data like your example:

  | A       | B        | C
1 | name    | position | points
2 | person1 | 1        | 10
3 | person2 | 2        | 9
4 | person3 | 2        | 9
5 | person4 | 2        | 9
6 | person5 | 5        | 8
7 | person6 | 6        | 7

The 'Points' column needs to be sorted into descending order.

THIS IS THE VB VERSION (Works with GREEK) :

Imports System.Text

Imports System.Globalization

Public Function RemoveDiacritics(ByVal s As String)
    Dim normalizedString As String
    Dim stringBuilder As New StringBuilder
    normalizedString = s.Normalize(NormalizationForm.FormD)
    Dim i As Integer
    Dim c As Char
    For i = 0 To normalizedString.Length - 1
        c = normalizedString(i)
        If CharUnicodeInfo.GetUnicodeCategory(c) <> UnicodeCategory.NonSpacingMark Then
            stringBuilder.Append(c)
        End If
    Next
    Return stringBuilder.ToString()
End Function

For uploading, the S3 SDK has two putObject methods:

PutObjectRequest(String bucketName, String key, File file)

and

PutObjectRequest(String bucketName, String key, InputStream input, ObjectMetadata metadata)

The inputstream+ObjectMetadata method needs a minimum metadata of Content Length of your inputstream. If you don't, then it will buffer in-memory to get that information, this could cause OOM. Alternatively, you could do your own in-memory buffering to get the length, but then you need to get a second inputstream.

Not asked by the OP (limitations of his environment), but for someone else, such as me. I find it easier, and safer (if you have access to temp file), to write the inputstream to a temp file, and put the temp file. No in-memory buffer, and no requirement to create a second inputstream.

AmazonS3 s3Service = new AmazonS3Client(awsCredentials);
File scratchFile = File.createTempFile("prefix", "suffix");
try {
    FileUtils.copyInputStreamToFile(inputStream, scratchFile);    
    PutObjectRequest putObjectRequest = new PutObjectRequest(bucketName, id, scratchFile);
    PutObjectResult putObjectResult = s3Service.putObject(putObjectRequest);

} finally {
    if(scratchFile.exists()) {
        scratchFile.delete();
    }
}

You just need 775 for /var/www/html as long as you are logging in as myuser. The 7 octal in the middle (which is for "group" acl) ensures that the group has permission to read/write/execute. As long as you belong to the group that owns the files, "myuser" should be able to write to them. You may need to give group permissions to all the files in the docuemnt root, though:

chmod -R g+w /var/www/html

Thanks to Flek for answering my question in his comment:

http://jsfiddle.net/eTTZj/30/

<div ng-app="myApp" scroll id="page" ng-class="{min:boolChangeClass}">

    <header></header>
    <section></section>

</div>

app = angular.module('myApp', []);
app.directive("scroll", function ($window) {
    return function(scope, element, attrs) {
        angular.element($window).bind("scroll", function() {
             if (this.pageYOffset >= 100) {
                 scope.boolChangeClass = true;
             } else {
                 scope.boolChangeClass = false;
             }
            scope.$apply();
        });
    };
});

This should be cross platform. At least for Linux and Mac OS X.

python -c 'import multiprocessing as mp; print(mp.cpu_count())'

A little bit slow but works.

Incase people have a problem like myself following Marwan Aouida's answer ... the code has a small typo. Instead of "success" it says "sucess" change the spelling and the code works fine.

Just put your data into an Object like this:

var myObject = new Object();
myObject.name = "John";
myObject.age = 12;
myObject.pets = ["cat", "dog"];

Afterwards stringify it via:

var myString = JSON.stringify(myObject);

You don't need jQuery for this. It's pure JS.

As others have suggested, you could use the following:

my $find = 'start (.*) end';
my $replace = 'foo $1 bar';   # 'foo \1 bar' is an error.
my $var = "start middle end";
$var =~ s/$find/$replace/ee;

The above is short for the following:

my $find = 'start (.*) end';
my $replace = 'foo $1 bar';
my $var = "start middle end";
$var =~ s/$find/ eval($replace) /e;

I prefer the second to the first since it doesn't hide the fact that eval(EXPR) is used. However, both of the above silence errors, so the following would be better:

my $find = 'start (.*) end';
my $replace = 'foo $1 bar';
my $var = "start middle end";
$var =~ s/$find/ my $r = eval($replace); die $@ if $@; $r /e;

But as you can see, all of the above allow for the execution of arbitrary Perl code. The following would be far safer:

use String::Substitution qw( sub_modify );

my $find = 'start (.*) end';
my $replace = 'foo $1 bar';
my $var = "start middle end";
sub_modify($var, $find, $replace);

You can use the built-in class XAttribute, which handles the encoding automatically:

using System.Xml.Linq;

XDocument doc = new XDocument();

List<XAttribute> attributes = new List<XAttribute>();
attributes.Add(new XAttribute("key1", "val1&val11"));
attributes.Add(new XAttribute("key2", "val2"));

XElement elem = new XElement("test", attributes.ToArray());

doc.Add(elem);

string xmlStr = doc.ToString();

RanRag has already answered it for your specific question.

However, more generally, what you are doing with

if [[ "$string" =~ ^hello ]]

is a regex match. To do the same in Python, you would do:

import re
if re.match(r'^hello', somestring):
    # do stuff

Obviously, in this case, somestring.startswith('hello') is better.

I ran into this problem after a fresh install of Android Studio (in GNU/Linux). I also used the installation wizard for Android SDK, and the Build Tools 28.0.3 were installed, although Android Studio tried to use 28.0.2 instead.

But the problem was not the build tools version but the license. I had not accepted the Android SDK license (the wizard does not ask for it), and Android Studio refused to use the build tools; the error message just is wrong.

In order to solve the problem, I manually accepted the license. In a terminal, I launched $ANDROID_SDK/tools/bin/sdkmanager --licenses and answered "Yes" for the SDK license. The other ones can be refused.

style="overflow: hidden" and style="resize: none" were the ones that did the trick.

We have found that adding the Apptentive cocoa pod to an existing Xcode project may potentially not include some of our required frameworks.

Check your linker flags:

Target > Build Settings > Other Linker Flags 

You should see -lApptentiveConnect listed as a linker flag:

... -ObjC -lApptentiveConnect ... 

You should also see our required Frameworks listed:

• Accelerate
• CoreData
• CoreText
• CoreGraphics
• CoreTelephony
• Foundation
• QuartzCore
• StoreKit
• SystemConfiguration

• UIKit

  -ObjC -lApptentiveConnect -framework Accelerate -framework CoreData -framework CoreGraphics -framework CoreText -framework Foundation -framework QuartzCore -framework SystemConfiguration -framework UIKit -framework CoreTelephony -framework StoreKit  

How about

1. First adding your desired result as arraylist and
2. and convert to double array as you want.

Try like this..

import java.util.ArrayList;
import java.util.List;

    public class ArrayTest {

        /**
         * @param args
         */
        public static void main(String[] args) {
            // TODO Auto-generated method stub

            // Your Prepared data. 
            List<double[]> values = new ArrayList<double[]>(2);

            double[] element1 = new double[] { 100, 100, 100, 100, 100 };
            double[] element2 = new double[] { 50, 35, 25, 45, 65 };

            values.add(element1);
            values.add(element2);

            // Add the result to arraylist.
            List<Double> temp = new ArrayList<Double>();
            for(int j=0;j<values.size(); j++) {
                for (int i = 0; i < values.get(0).length; i++) {
                    temp.add(values.get(0)[i]);
                    temp.add(values.get(1)[i]);
                }
            }

            // Convert arraylist to int[].
            Double[] result = temp.toArray(new Double[temp.size()]);
            double[] finalResult = new double[result.length]; // This hold final result.
            for (int i = 0; i < result.length; i++) {
                finalResult[i] = result[i].doubleValue();
            }

            for (int i = 0; i < finalResult.length; i++) {
                System.out.println(finalResult[i]);
            }
        }
    }

as a quick fix to this question, make sure your compile Sdk verion, your buildtoolsversion, your appcompat, and finally your support library are all running on the same sdk version, for further clarity take a look at the image i just uploaded. Cheers. Follow the red annotations and get rid of that trouble.

you can use inner join :

DELETE 
    ps 
FROM 
    posts ps INNER JOIN 
         (SELECT 
           distinct id 
         FROM 
             posts 
         GROUP BY id  
      HAVING COUNT(id) > 1 ) dubids on dubids.id = ps.id  

Solution:

in WINDOWS you should write "\r\n" for a new line.

On my system (Windows 8.1), Sublime 2 shows default font "Consolas". You can find yours by following this procedure:

1. go to View menu and select Show Console
2. Then enter this command: view.settings().get('font_face')

You will find your default font.

function getDialogButton( jqUIdialog, button_names )
{
    if (typeof button_names == 'string')
        button_names = [button_names];
    var buttons = jqUIdialog.parent().find('.ui-dialog-buttonpane button');
    for (var i = 0; i < buttons.length; i++)
    {
        var jButton = $( buttons[i] );
        for (var j = 0; j < button_names.length; j++)
            if ( jButton.text() == button_names[j] )
                return jButton;
    }

    return null;
}

function enableDialogButton( jqUIdialog, button_names, enable )
{
    var button = getDialogButton( jqUIdialog, button_names );
    if (button == null)
        alert('button not found: '+button_names);
    else
    {
        if (enable)
            button.removeAttr('disabled').removeClass( 'ui-state-disabled' );
        else
            button.attr('disabled', 'disabled').addClass( 'ui-state-disabled' );
    }
}

Try working with this C# snippet I just crafted:

using System;
using System.IO;
using System.Security.AccessControl;
using System.Security.Principal;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string directory = @"C:\downloads";

            DirectoryInfo di = new DirectoryInfo(directory);

            DirectorySecurity ds = di.GetAccessControl();

            foreach (AccessRule rule in ds.GetAccessRules(true, true, typeof(NTAccount)))
            {
                Console.WriteLine("Identity = {0}; Access = {1}", 
                              rule.IdentityReference.Value, rule.AccessControlType);
            }
        }
    }
}

And here's a reference you could also look at. My code might give you an idea as to how you could check for permissions before attempting to write to a directory.

Tips to prevent issue (bad hash) :

I experienced that NodeJS is hashing the UTF-8 representation of the string. Other languages (like Python, PHP or PERL...) are hashing the byte string.

We can add binary argument to use the byte string.

const crypto = require("crypto");

function sha1(data) {
    return crypto.createHash("sha1").update(data, "binary").digest("hex");
}

sha1("Your text ;)");

You can try with : "\xac", "\xd1", "\xb9", "\xe2", "\xbb", "\x93", etc...

Other languages (Python, PHP, ...):

sha1("\xac") //39527c59247a39d18ad48b9947ea738396a3bc47

Nodejs:

sha1 = crypto.createHash("sha1").update("\xac", "binary").digest("hex") //39527c59247a39d18ad48b9947ea738396a3bc47
//without:
sha1 = crypto.createHash("sha1").update("\xac").digest("hex") //f50eb35d94f1d75480496e54f4b4a472a9148752

Arrays.fill(arrayName,value);

in java

int arrnum[] ={5,6,9,2,10};
for(int i=0;i<arrnum.length;i++){
  System.out.println(arrnum[i]+" ");
}
Arrays.fill(arrnum,0);
for(int i=0;i<arrnum.length;i++){
  System.out.println(arrnum[i]+" ");
}

Output

5 6 9 2 10
0 0 0 0 0

Just my 2 cents in case someone stumble upon this :)

What I am suggesting here will have the same result as the current answer however it has been recommended to write your controller the way that I have mentioned here.

Reference scroll to the first "Note" (Sorry it doesn't have anchor)

Here is the recommended way:

Controller:

var app = angular.module('myApp', []);   
app.controller( 'MyCtrl', ['$scope', function($scope) {
    $scope.date = new Date();
}]);

View:

<div ng-app="myApp">
  <div ng-controller="MyCtrl">
    {{date | date:'yyyy-MM-dd'}}
  </div>
</div>

dict.iteritems was removed because dict.items now does the thing dict.iteritems did in python 2.x and even improved it a bit by making it an itemview.

Yes, as long as the url you type into the browser www.someshopping.com and you aren't using url rewriting then

string currentURL = HttpContext.Current.Request.Url.Host;

will return www.someshopping.com

Note the difference between a local debugging environment and a production environment

var timeoutId = 0;

$('#myElement').on('mousedown', function() {
    timeoutId = setTimeout(myFunction, 1000);
}).on('mouseup mouseleave', function() {
    clearTimeout(timeoutId);
});

Edit: correction per AndyE...thanks!

Edit 2: using bind now for two events with same handler per gnarf

You can do something like this.

bind your event into a common function and call the event either with keypress or button click.

for example.

function callME(event){
    alert('Hi');
}



$('button').on("click",callME); 
$('input ').keypress(function(event){
  if (event.which == 13) {
    callME(event);
  }
});

I think it would be easier using this CLR Stored procedure SQL-APIConsumer:

 exec [dbo].[APICaller_POST]
     @URL = 'http://localhost:5000/api/auth/login'
    ,@BodyJson = '{"Username":"gdiaz","Password":"password"}'

It has multiple procedures that allows you calling API that required a parameters and even passing multiples headers and tokens authentications.

1) Open psql terminal.

2) Unzip/ untar the dump file.

3) Create an empty database.

4) use the following command to restore the .dump file

<database_name>-# \i <path_to_.dump_file>

When I'm working with csv files, I often use the pandas library. It makes things like this very easy. For example:

import pandas as pd

a = pd.read_csv("filea.csv")
b = pd.read_csv("fileb.csv")
b = b.dropna(axis=1)
merged = a.merge(b, on='title')
merged.to_csv("output.csv", index=False)

Some explanation follows. First, we read in the csv files:

>>> a = pd.read_csv("filea.csv")
>>> b = pd.read_csv("fileb.csv")
>>> a
   title  stage    jan    feb
0   darn  3.001  0.421  0.532
1     ok  2.829  1.036  0.751
2  three  1.115  1.146  2.921
>>> b
   title    mar    apr    may       jun  Unnamed: 5
0   darn  0.631  1.321  0.951    1.7510         NaN
1     ok  1.001  0.247  2.456    0.3216         NaN
2  three  0.285  1.283  0.924  956.0000         NaN

and we see there's an extra column of data (note that the first line of fileb.csv -- title,mar,apr,may,jun, -- has an extra comma at the end). We can get rid of that easily enough:

>>> b = b.dropna(axis=1)
>>> b
   title    mar    apr    may       jun
0   darn  0.631  1.321  0.951    1.7510
1     ok  1.001  0.247  2.456    0.3216
2  three  0.285  1.283  0.924  956.0000

Now we can merge a and b on the title column:

>>> merged = a.merge(b, on='title')
>>> merged
   title  stage    jan    feb    mar    apr    may       jun
0   darn  3.001  0.421  0.532  0.631  1.321  0.951    1.7510
1     ok  2.829  1.036  0.751  1.001  0.247  2.456    0.3216
2  three  1.115  1.146  2.921  0.285  1.283  0.924  956.0000

and finally write this out:

>>> merged.to_csv("output.csv", index=False)

producing:

title,stage,jan,feb,mar,apr,may,jun
darn,3.001,0.421,0.532,0.631,1.321,0.951,1.751
ok,2.829,1.036,0.751,1.001,0.247,2.456,0.3216
three,1.115,1.146,2.921,0.285,1.283,0.924,956.0

Yes there is such a built-in function: os.path.join.

>>> import os.path
>>> os.path.join('/my/root/directory', 'in', 'here')
'/my/root/directory/in/here'

Use StringUtils.isAlpha() method and it will make your life simple.

This is a quick hacky way: ls -lart | grep -v ^total.

Basically, remove any lines that start with "total", which in ls output should only be the first line.

A more general way (for anything):

ls -lart | sed "1 d"

sed "1 d" means only print everything but first line.

I found James Wald's answer the closest to my solution, except instead of "File->Import->General->Existing Projects into Workspace" (which did not work for me at all) I used "File->Import->Android->Existing Android Code Into Workspace". I am using Helios, maybe your version of Eclipse does not have this quirk.

Big thanks to Mike and Robertc for their helpful posts!

If you have two elements in your HTML and you want to :hover over one and target a style change in the other the two elements must be directly related--parents, children or siblings. This means that the two elements either must be one inside the other or must both be contained within the same larger element.

I wanted to display definitions in a box on the right side of the browser as my users read through my site and :hover over highlighted terms; therefore, I did not want the 'definition' element to be displayed inside the 'text' element.

I almost gave up and just added javascript to my page, but this is the future dang it! We should not have to put up with back sass from CSS and HTML telling us where we have to place our elements to achieve the effects we want! In the end we compromised.

While the actual HTML elements in the file must be either nested or contained in a single element to be valid :hover targets to each other, the css position attribute can be used to display any element where ever you want. I used position:fixed to place the target of my :hover action where I wanted it on the user's screen regardless to its location in the HTML document.

The html:

<div id="explainBox" class="explainBox"> /*Common parent*/

  <a class="defP" id="light" href="http://en.wikipedia.or/wiki/Light">Light                            /*highlighted term in text*/
  </a> is as ubiquitous as it is mysterious. /*plain text*/

  <div id="definitions"> /*Container for :hover-displayed definitions*/
    <p class="def" id="light"> /*example definition entry*/ Light:
      <br/>Short Answer: The type of energy you see
    </p>
  </div>

</div>

The css:

/*read: "when user hovers over #light somewhere inside #explainBox
    set display to inline-block for #light directly inside of #definitions.*/

#explainBox #light:hover~#definitions>#light {
  display: inline-block;
}

.def {
  display: none;
}

#definitions {
  background-color: black;
  position: fixed;
  /*position attribute*/
  top: 5em;
  /*position attribute*/
  right: 2em;
  /*position attribute*/
  width: 20em;
  height: 30em;
  border: 1px solid orange;
  border-radius: 12px;
  padding: 10px;
}

In this example the target of a :hover command from an element within #explainBox must either be #explainBox or also within #explainBox. The position attributes assigned to #definitions force it to appear in the desired location (outside #explainBox) even though it is technically located in an unwanted position within the HTML document.

I understand it is considered bad form to use the same #id for more than one HTML element; however, in this case the instances of #light can be described independently due to their respective positions in uniquely #id'd elements. Is there any reason not to repeat the id #light in this case?

If you don't use ngRoute module, i.e. you don't have $viewContentLoaded event.

You can use another directive method:

    angular.module('someModule')
        .directive('someDirective', someDirective);

    someDirective.$inject = ['$rootScope', '$timeout']; //Inject services

    function someDirective($rootScope, $timeout){
        return {
            restrict: "A",
            priority: Number.MIN_SAFE_INTEGER, //Lowest priority
            link    : function(scope, element, attr){
                $timeout(
                    function(){
                        $rootScope.$emit("Some:event");
                    }
                );
            }
        };
    }

Accordingly to trusktr's answer it has lowest priority. Plus $timeout will cause Angular to run through an entire event loop before callback execution.

$rootScope used, because it allow to place directive in any scope of the application and notify only necessary listeners.

$rootScope.$emit will fire an event for all $rootScope.$on listeners only. The interesting part is that $rootScope.$broadcast will notify all $rootScope.$on as well as $scope.$on listeners Source

you can integrate to LDAP or AD as well. It works well.

#include <memory>
#include <iostream>

class SharedMemory {
    public: 
        SharedMemory(int* x):_capture(x){}
        int* get() { return (_capture.get()); }
    protected:
        std::shared_ptr<int> _capture;
};

int main(int , char**){
    SharedMemory *_obj1= new SharedMemory(new int(10));
    SharedMemory *_obj2 = new SharedMemory(*_obj1);
    std::cout << " _obj1: " << *_obj1->get() << " _obj2: " << *_obj2->get()
    << std::endl;
    delete _obj2;

    std::cout << " _obj1: " << *_obj1->get() << std::endl;
    delete _obj1;
    std::cout << " done " << std::endl;
}

This is an example of shared_ptr in action. _obj2 was deleted but pointer is still valid. output is, ./test _obj1: 10 _obj2: 10 _obj2: 10 done

You can use Location as mentioned here.

Here's my code if the link opened on new tab

navBack() {
    let cur_path = this.location.path();
    this.location.back();
    if (cur_path === this.location.path())
     this.router.navigate(['/default-route']);    
  }

Required imports

import { Router } from '@angular/router';
import { Location } from '@angular/common';

If you are using bootstrap v4 there is a new way to do that.

You should use .dropdown-menu-right on the .dropdown-menu element.

<div class="btn-group">
  <button type="button" class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
    Right-aligned menu
  </button>
  <div class="dropdown-menu dropdown-menu-right">
    <button class="dropdown-item" type="button">Action</button>
    <button class="dropdown-item" type="button">Another action</button>
    <button class="dropdown-item" type="button">Something else here</button>
  </div>
</div>

I had the same problem. In my case cordova platform update ios helped. The reason was in outdated version.

For a great tutorial the Mozilla Developer Network page on this functionality is all you'll need: https://developer.mozilla.org/en/DOM/Manipulating_the_browser_history

Unfortunately, the HTML5 History API is implemented differently in all the HTML5 browsers (making it inconsistent and buggy) and has no fallback for HTML4 browsers. Fortunately, History.js provides cross-compatibility for the HTML5 browsers (ensuring all the HTML5 browsers work as expected) and optionally provides a hash-fallback for HTML4 browsers (including maintained support for data, titles, pushState and replaceState functionality).

You can read more about History.js here: https://github.com/browserstate/history.js

For an article about Hashbangs VS Hashes VS HTML5 History API, see here: https://github.com/browserstate/history.js/wiki/Intelligent-State-Handling

• \r = CR (Carriage Return) → Used as a new line character in Mac OS before X
• \n = LF (Line Feed) → Used as a new line character in Unix/Mac OS X
• \r\n = CR + LF → Used as a new line character in Windows

To execute a binary, use: ./binary_name.

If you get an error:

bash: ./binary_name: cannot execute binary file

it'll be because it was compiled using a tool chain that was for a different target to that which you're attempting to run the binary on.

For example, if you compile 'binary_name.c' with arm-none-linux-gnueabi-gcc and try run the generated binary on an x86 machine, you will get the aforementioned error.

I think the fastest way to do this is:

GradientDrawable gradientDrawable = new GradientDrawable(
            GradientDrawable.Orientation.TOP_BOTTOM, //set a gradient direction 
            new int[] {0xFF757775,0xFF151515}); //set the color of gradient
gradientDrawable.setCornerRadius(10f); //set corner radius

//Apply background to your view
View view = (RelativeLayout) findViewById( R.id.my_view );
if(Build.VERSION.SDK_INT>=16)
     view.setBackground(gradientDrawable);
else view.setBackgroundDrawable(gradientDrawable);    

You need to take out the $ signs before the row numbers in the formula....and the row number used in the formula should correspond to the first row of data, so if you are applying this to the ("applies to") range $B$2:$B$5 it must be this formula

=$B2>$C2

by using that "relative" version rather than your "absolute" one Excel (implicitly) adjusts the formula for each row in the range, as if you were copying the formula down

Include the following method

-(void)viewDidLayoutSubviews{
    self.automaticallyAdjustsScrollViewInsets = NO;
}

and set the content size width of the scroll view equal to the width of the scroll view.

Easy way:

String reverseString(String string)
{
    String newString = "";
    for(int x = string.length() - 1; x > -1; x ++)
        newString += string.charAt(x);
    return newString;
}

Can't. Interfaces don't exist at runtime.

workaround

Create a variable of the type and use Object.keys on it

If you want to put some page in the dialog then you can use these

function Popup()
{
 $("#pop").load('login.html').dialog({
 height: 625,
 width: 600,
 modal:true,
 close: function(event,ui){
     $("pop").dialog('destroy');

        }
 }); 

}

HTML:

<Div id="pop"  style="display:none;">

</Div>

Sometimes, you only need this code.

Here is a simple program that displays the camera feed in a cv2.namedWindow and will take a snapshot when you hit SPACE. It will also quit if you hit ESC.

import cv2

cam = cv2.VideoCapture(0)

cv2.namedWindow("test")

img_counter = 0

while True:
    ret, frame = cam.read()
    if not ret:
        print("failed to grab frame")
        break
    cv2.imshow("test", frame)

    k = cv2.waitKey(1)
    if k%256 == 27:
        # ESC pressed
        print("Escape hit, closing...")
        break
    elif k%256 == 32:
        # SPACE pressed
        img_name = "opencv_frame_{}.png".format(img_counter)
        cv2.imwrite(img_name, frame)
        print("{} written!".format(img_name))
        img_counter += 1

cam.release()

cv2.destroyAllWindows()

I think this should answer your question for the most part. If there is any line of it that you don't understand let me know and I'll add comments.

If you need to grab multiple images per press of the SPACE key, you will need an inner loop or perhaps just make a function that grabs a certain number of images.

Note that the key events are from the cv2.namedWindow so it has to have focus.

I know its old post but still I want to contribute
Above will not work if you have data format like this
'YYYMMDD'

For example:

Dt
20151104

So I tried following in order to get the desired result.

select cast(Left('20151104', 4)||'-'||substring('20151104',5,2)||'-'||substring('20151104', 7,2) as date) from SYSIBM.SYSDUMMY1;

Additionally, If you want to run the query from MS SQL linked server to DB2(To display only 100 rows).

    SELECT top 100 * from OPENQUERY([Linked_Server_Name],
    'select cast(Left(''20151104'', 4)||''-''||substring(''20151104'',5,2)||''-''||substring(''20151104'', 7,2) as date) AS Dt 
    FROM SYSIBM.SYSDUMMY1')

Result after above query:

Dt
2015-11-04

Hope this helps for others.

Sounds like you're doing this:

0..10.to_a

The warning is from Fixnum#to_a, not from Range#to_a. Try this instead:

(0..10).to_a

By the way, a good tip on quickly selecting color on the newer versions of AS is simply to type #fff and then using the color picker on the side of the code to choose the one you want. Quick and easier than remembering all the color hexadecimals. For example:

android:background="#fff"

htmlStr is string then You need to Date and Time variables to string

while (reader.Read())
                {
                    DateTime Date = reader.GetDateTime(0);
                    DateTime Time = reader.GetDateTime(1);
                    htmlStr += "<tr><td>" + Date.ToString() + "</td><td>"  + 
                    Time.ToString() + "</td></tr>";                  
                }

• LibHaru seems to be used by many.

A non-open source approach is: PDF Creator Pilot which provides more language options including C++, C#, Delphi, ASP, ASP.NET, VB, VB.NET, VBScript, PHP and Python

I'm looking at this and thinking, if you can only get variables into php in a form, why not just make a form and put a hidden input in the thing so it doesn't show on screen, and then put the value from your javascript into the hidden input and POST that into the php? It would sure be a lot less hassle than some of this other stuff right?

If it is possible to change the sequence of the lines you could do:

1. sort line with Edit -> Line Operations -> Sort Lines Lexicographically ascending
2. do a Find / Replace:
   • Find What: ^(.*\r?\n)\1+
   • Replace with: (Nothing, leave empty)
   • Check Regular Expression in the lower left
   • Click Replace All

How it works: The sorting puts the duplicates behind each other. The find matches a line ^(.*\r?\n) and captures the line in \1 then it continues and tries to find \1 one or more times (+) behind the first match. Such a block of duplicates (if it exists) is replaced with nothing.

The \r?\n should deal nicely with Windows and Unix lineendings.

In your modal body you have to set a height, it can be % vh or calc:

modal-body {
    height: 80vh;
    overflow-x: auto;
}

or

modal-body {
    height: calc(100vh - 5em);
    overflow-x: auto;
}

In my case look like:

Their is no agreement on the rest api response formats of big software giants - Google, Facebook, Twitter, Amazon and others, though many links have been provided in the answers above, where some people have tried to standardize the response format.

As needs of the API's can differ it is very difficult to get everyone on board and agree to some format. If you have millions of users using your API, why would you change your response format?

Following is my take on the response format inspired by Google, Twitter, Amazon and some posts on internet:

git pull is really just a shorthand for git pull <remote> <branchname>, in most cases it's equivalent to git pull origin master. You will need to add another remote and pull explicitly from it. This page describes it in detail:

For all those who came here and did indeed use Date typed Variables, here is the solution I found. It does also apply to TypeScript.

I was facing this error because I tried to compare two dates using the following Method

var res = dat1.getTime() > dat2.getTime(); // or any other comparison operator

However Im sure I used a Date object, because Im using angularjs with typescript, and I got the data from a typed API call.

Im not sure why the error is raised, but I assume that because my Object was created by JSON deserialisation, possibly the getTime() method was simply not added to the prototype.

Solution

In this case, recreating a date-Object based on your dates will fix the issue.

var res = new Date(dat1).getTime() > new Date(dat2).getTime()

Edit:

I was right about this. Types will be cast to the according type but they wont be instanciated. Hence there will be a string cast to a date, which will obviously result in a runtime exception.

The trick is, if you use interfaces with non primitive only data such as dates or functions, you will need to perform a mapping after your http request.

class Details {
    description: string;
    date: Date;
    score: number;
    approved: boolean;

    constructor(data: any) {
      Object.assign(this, data);
    }
}

and to perform the mapping:

public getDetails(id: number): Promise<Details> {
    return this.http
               .get<Details>(`${this.baseUrl}/api/details/${id}`)
               .map(response => new Details(response.json()))
               .toPromise();
}

for arrays use:

public getDetails(): Promise<Details[]> {
    return this.http
               .get<Details>(`${this.baseUrl}/api/details`)
               .map(response => {
                   const array = JSON.parse(response.json()) as any[];
                   const details = array.map(data => new Details(data));
                   return details;
               })
               .toPromise();
}

I faced a similar problem, but I just knocked up a very short C++ console application to do the same thing. Just run MySleep.exe 1000 - perhaps easier than downloading/installing the whole resource kit.

#include "Windows.h"

        _tprintf(_T("Sleeping for %s ms\n"), argv[1]);
        Sleep(_tstoi(argv[1]));
    }
    else
    {
        _tprintf(_T("Wrong number of arguments.\n"));
    }
    return 0;
}
