Encountered a similar error, this how I resolved it:

1. Access Project explorer view on Netbeans IDE 8.2. Proceed to your project under Dependencies hover the cursor over the log4j-over-slf4j.jar to view the which which dependencies have indirectly imported as shown below.

2. Right click an import jar file and select Exclude Dependency

3. To confirm, open your pom.xml file you will notice the exclusion element as below.

4. Initiate maven clean install and run your project. Good luck!

A default object must be a property list—that is, an instance of (or for collections, a combination of instances of): NSData, NSString, NSNumber, NSDate, NSArray, or NSDictionary.

If you want to store any other type of object, you should typically archive it to create an instance of NSData. For more details, see Preferences and Settings Programming Guide.

You can also create custom states and update it's value duting task execution. This example is from docs:

@app.task(bind=True)
def upload_files(self, filenames):
    for i, file in enumerate(filenames):
        if not self.request.called_directly:
            self.update_state(state='PROGRESS',
                meta={'current': i, 'total': len(filenames)})

It really depends on many settings, on both the audio and video side of things. If you follow the compression-settings of this video, then it's approximately 3GB per hour. If you have a Mac, I would definitely recommend using 'Compressor' as it is fairly easy to use and works flawless.

As far as storage is concerned, if you're looking at 100hrs / 300GB, I would definitely go with an external hard drive. Video files are so huge, that they (even if they don't totally fill up your hard disk) really do confuse your computer. Make sure to make some time for compressing the whole thing because it takes hours and hours and hours.... for 100 hrs worth of footage, it'll take days.

I found this question when searching for a solution to a code page issue i had with Chinese characters, but in the end my problem was just an issue with Windows not displaying them correctly in the UI.

In case anyone else has that same issue, you can fix it simply by changing the local in windows to China and then back again.

I found the solution here:

Also upvoted Gabriel's answer as looking at the data in notepad++ was what tipped me off about windows.

Microsoft provides us built-in functionality which we use in our application for security purposes, so no one can hack our site or invade some critical information.

From Purpose Of ValidateAntiForgeryToken In MVC Application by Harpreet Singh:

Use of ValidateAntiForgeryToken

Let’s try with a simple example to understand this concept. I do not want to make it too complicated, that’s why I am going to use a template of an MVC application, already available in Visual Studio. We will do this step by step. Let’s start.

1. Step 1 - Create two MVC applications with default internet template and give those names as CrossSite_RequestForgery and Attack_Application respectively.

2. Now, open CrossSite_RequestForgery application's Web Config and change the connection string with the one given below and then save.

`

<connectionStrings> <add name="DefaultConnection" connectionString="Data Source=local\SQLEXPRESS;Initial Catalog=CSRF;
Integrated Security=true;" providerName="System.Data.SqlClient" /> 
 </connectionStrings>

3. Now, click on Tools >> NuGet Package Manager, then Package Manager Console

4. Now, run the below mentioned three commands in Package Manager Console to create the database.

Enable-Migrations add-migration first update-database

Important Notes - I have created database with code first approach because I want to make this example in the way developers work. You can create database manually also. It's your choice.

5. Now, open Account Controller. Here, you will see a register method whose type is post. Above this method, there should be an attribute available as [ValidateAntiForgeryToken]. Comment this attribute. Now, right click on register and click go to View. There again, you will find an html helper as @Html.AntiForgeryToken() . Comment this one also. Run the application and click on register button. The URL will be open as:

http://localhost:52269/Account/Register

Notes- I know now the question being raised in all readers’ minds is why these two helpers need to be commented, as everyone knows these are used to validate request. Then, I just want to let you all know that this is just because I want to show the difference after and before applying these helpers.

6. Now, open the second application which is Attack_Application. Then, open Register method of Account Controller. Just change the POST method with the simple one, shown below.

   Registration Form
   1. @Html.LabelFor(m => m.UserName) @Html.TextBoxFor(m => m.UserName)
   2. @Html.LabelFor(m => m.Password) @Html.PasswordFor(m => m.Password)
   3. @Html.LabelFor(m => m.ConfirmPassword) @Html.PasswordFor(m => m.ConfirmPassword)

7.Now, suppose you are a hacker and you know the URL from where you can register user in CrossSite_RequestForgery application. Now, you created a Forgery site as Attacker_Application and just put the same URL in post method.

8.Run this application now and fill the register fields and click on register. You will see you are registered in CrossSite_RequestForgery application. If you check the database of CrossSite_RequestForgery application then you will see and entry you have entered.

9. Important - Now, open CrossSite_RequestForgery application and comment out the token in Account Controller and register the View. Try to register again with the same process. Then, an error will occur as below.

Server Error in '/' Application. ________________________________________ The required anti-forgery cookie "__RequestVerificationToken" is not present.

This is what the concept says. What we add in View i.e. @Html.AntiForgeryToken() generates __RequestVerificationToken on load time and [ValidateAntiForgeryToken] available on Controller method. Match this token on post time. If token is the same, then it means this is a valid request.

From the "View" menu, select "Workspaces". You'll see all of the workspaces you've created. Select the workspaces you want to delete and click "Edit" -> "Delete Workspace", or right-click and select "Delete Workspace". If the workspace is "locked" to prevent changes, you'll get an error message.

To unlock the workspace, click "Edit" (or right-click and click "Edit Workspace") to pull up the workspace editor, uncheck the "locked" checkbox, and save your changes. You can delete the workspace once it's unlocked.

In my experience, the workspace will continue to be shown in the drop-down list until you click on it, at which point p4v will figure out you've deleted it and remove it from the list.

In addition to cookies and localStorage, there's at least one other place you can store "semi-persistent" client data: window.name. Any string value you assign to window.name will stay there until the window is closed.

To test it out, just open the console and type window.name = "foo", then refresh the page and type window.name; it should respond with foo.

This is a bit of a hack, but if you don't want cookies filled with unnecessary data being sent to the server with every request, and if you can't use localStorage for whatever reason (legacy clients), it may be an option to consider.

window.name has another interesting property: it's visible to windows served from other domains; it's not subject to the same-origin policy like nearly every other property of window. So, in addition to storing "semi-persistent" data there while the user navigates or refreshes the page, you can also use it for CORS-free cross-domain communication.

Note that window.name can only store strings, but with the wide availability of JSON, this shouldn't be much of an issue even for complex data.

Your reference image looks like a button. Try (can also be done in Interface Builder):

UIButton* button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setFrame:CGRectMake(50, 50, 100, 44)];
[button setImage:[UIImage imageNamed:@"img"] forState:UIControlStateNormal];
[button setImageEdgeInsets:UIEdgeInsetsMake(0, -30, 0, 0)];
[button setTitle:@"Abc" forState:UIControlStateNormal];
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[button setBackgroundColor:[UIColor yellowColor]];
[view addSubview:button];

You can also access the principal using the User property on ApiController.

So the following two statements are basically the same:

string id;
id = User.Identity.GetUserId();
id = RequestContext.Principal.Identity.GetUserId();

function bookmark(title, url) {
  if (window.sidebar) { 
    // Firefox
    window.sidebar.addPanel(title, url, '');
  } 
  else if (window.opera && window.print) 
  { 
    // Opera
    var elem = document.createElement('a');
    elem.setAttribute('href', url);
    elem.setAttribute('title', title);
    elem.setAttribute('rel', 'sidebar');
    elem.click(); //this.title=document.title;
  } 
  else if (document.all) 
  { 
    // ie
    window.external.AddFavorite(url, title);
  }
}

I used this & works great in IE, FF, Netscape. Chrome, Opera and safari do not support it!

I think you are in luck. Please try entering in B1:

(very similar!) but before hitting Enter hit Ctrl+Shift+Enter.

You can use a BehaviorSubject for communicating between different components throughout the app. You can define a data sharing service containing the BehaviorSubject to which you can subscribe and emit changes.

Define a data sharing service

import { Injectable } from '@angular/core';
import { BehaviorSubject } from 'rxjs';

@Injectable()
export class DataSharingService {
    public isUserLoggedIn: BehaviorSubject<boolean> = new BehaviorSubject<boolean>(false);
}

Add the DataSharingService in your AppModule providers entry.

Next, import the DataSharingService in your <app-header> and in the component where you perform the sign-in operation. In <app-header> subscribe to the changes to isUserLoggedIn subject:

import { DataSharingService } from './data-sharing.service';

export class AppHeaderComponent { 
    // Define a variable to use for showing/hiding the Login button
    isUserLoggedIn: boolean;

    constructor(private dataSharingService: DataSharingService) {

        // Subscribe here, this will automatically update 
        // "isUserLoggedIn" whenever a change to the subject is made.
        this.dataSharingService.isUserLoggedIn.subscribe( value => {
            this.isUserLoggedIn = value;
        });
    }
}

In your <app-header> html template, you need to add the *ngIf condition e.g.:

<button *ngIf="!isUserLoggedIn">Login</button> 
<button *ngIf="isUserLoggedIn">Sign Out</button>

Finally, you just need to emit the event once the user has logged in e.g:

someMethodThatPerformsUserLogin() {
    // Some code 
    // .....
    // After the user has logged in, emit the behavior subject changes.
    this.dataSharingService.isUserLoggedIn.next(true);
}

The extreme and simple cases:

• A compiler will produce a binary executable in the target machine's native executable format. This binary file contains all required resources except for system libraries; it's ready to run with no further preparation and processing and it runs like lightning because the code is the native code for the CPU on the target machine.

• An interpreter will present the user with a prompt in a loop where he can enter statements or code, and upon hitting RUN or the equivalent the interpreter will examine, scan, parse and interpretatively execute each line until the program runs to a stopping point or an error. Because each line is treated on its own and the interpreter doesn't "learn" anything from having seen the line before, the effort of converting human-readable language to machine instructions is incurred every time for every line, so it's dog slow. On the bright side, the user can inspect and otherwise interact with his program in all kinds of ways: Changing variables, changing code, running in trace or debug modes... whatever.

With those out of the way, let me explain that life ain't so simple any more. For instance,

• Many interpreters will pre-compile the code they're given so the translation step doesn't have to be repeated again and again.
• Some compilers compile not to CPU-specific machine instructions but to bytecode, a kind of artificial machine code for a ficticious machine. This makes the compiled program a bit more portable, but requires a bytecode interpreter on every target system.
• The bytecode interpreters (I'm looking at Java here) recently tend to re-compile the bytecode they get for the CPU of the target section just before execution (called JIT). To save time, this is often only done for code that runs often (hotspots).
• Some systems that look and act like interpreters (Clojure, for instance) compile any code they get, immediately, but allow interactive access to the program's environment. That's basically the convenience of interpreters with the speed of binary compilation.
• Some compilers don't really compile, they just pre-digest and compress code. I heard a while back that's how Perl works. So sometimes the compiler is just doing a bit of the work and most of it is still interpretation.

In the end, these days, interpreting vs. compiling is a trade-off, with time spent (once) compiling often being rewarded by better runtime performance, but an interpretative environment giving more opportunities for interaction. Compiling vs. interpreting is mostly a matter of how the work of "understanding" the program is divided up between different processes, and the line is a bit blurry these days as languages and products try to offer the best of both worlds.

Check that you're not overriding window.self

My issue: I had created a component and wrote self = this instead of var self = this. If you don't use the keyword var, JS will put that variable on the window object, so I overwrote window.self which caused this error.

Convert a string to a DateTime, you could try

    DateTime timeValue = Convert.ToDateTime("01:00 PM");
    Console.WriteLine(timeValue.ToString("HH:mm"));

There's no difference between list implementations in both of your examples. There's however a difference in a way you can further use variable myList in your code.

When you define your list as:

List myList = new ArrayList();

you can only call methods and reference members that are defined in the List interface. If you define it as:

ArrayList myList = new ArrayList();

you'll be able to invoke ArrayList-specific methods and use ArrayList-specific members in addition to those whose definitions are inherited from List.

Nevertheless, when you call a method of a List interface in the first example, which was implemented in ArrayList, the method from ArrayList will be called (because the List interface doesn't implement any methods).

That's called polymorphism. You can read up on it.

It also happens if you're trying to access an instance when you have a pointer, and vice versa:

struct foo
{
  int x, y, z;
};

struct foo a, *b = &a;

b.x = 12;  /* This will generate the error, should be b->x or (*b).x */

As pointed out in a comment, this can be made excruciating if someone goes and typedefs a pointer, i.e. includes the * in a typedef, like so:

typedef struct foo* Foo;

Because then you get code that looks like it's dealing with instances, when in fact it's dealing with pointers:

Foo a_foo = get_a_brand_new_foo();
a_foo->field = FANTASTIC_VALUE;

Note how the above looks as if it should be written a_foo.field, but that would fail since Foo is a pointer to struct. I strongly recommend against typedef:ed pointers in C. Pointers are important, don't hide your asterisks. Let them shine.

You can read files in raw/res using getResources().openRawResource(R.raw.myfilename).

BUT there is an IDE limitation that the file name you use can only contain lower case alphanumeric characters and dot. So file names like XYZ.txt or my_data.bin will not be listed in R.

you can just add 1

<li v-for="(catalog, itemObjKey) in catalogs">this index : {{itemObjKey + 1}}</li>

to get the length of an array/objects

{{ catalogs.length }}

The installer from the git homepage installs into /usr/local/git by default. See also this answer. However, if you install XCode4, it will install a git version in /usr/bin. To ensure you can easily upgrade from the website and use the latest git version, edit either your profile information to place /usr/local/git/bin before /usr/bin in the $PATH or edit /etc/paths and insert /usr/local/git/bin as the first entry (see this answer).

@victor hugo and @unwind are correct, and victor's solution is by far the simplest. However BEWARE of externals in your SVN project. If you reference external libraries, the external's revision reference (whether a tag, or HEAD, or number) will remain unchanged when you tag directories that have external references.

It is possible to create a script to handle this aspect of tagging, for a discussion on that topic, see this SO article: Tagging an SVN checkout with externals

I have a simpler solution. In your destination page (irc_online.php) add an auto-refresh tag in the header.

Since I found this question not being aware, that mysql always stores time in timestamp fields in UTC but will display (e.g. phpmyadmin) in local time zone I would like to add my findings.

I have an automatically updated last_modified field, defined as:

`last_modified` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP

Looking at it with phpmyadmin, it looks like it is in local time, internally it is UTC

SET time_zone = '+04:00'; // or '+00:00' to display dates in UTC or 'UTC' if time zones are installed.
SELECT last_modified, UNIX_TIMESTAMP(last_modified), from_unixtime(UNIX_TIMESTAMP(last_modified), '%Y-%c-%d %H:%i:%s'), CONVERT_TZ(last_modified,@@session.time_zone,'+00:00') as UTC FROM `table_name`

In any constellation, UNIX_TIMESTAMP and 'as UTC' are always displayed in UTC time.

Run this twice, first without setting the time_zone.

wordlists is not a function, it is a list. You need the bracket subscript

print  wordlists[len(words)]

This works fine:

os.path.join(dir_name, base_filename + "." + filename_suffix)

Keep in mind that os.path.join() exists only because different operating systems use different path separator characters. It smooths over that difference so cross-platform code doesn't have to be cluttered with special cases for each OS. There is no need to do this for file name "extensions" (see footnote) because they are always connected to the rest of the name with a dot character, on every OS.

If using a function anyway makes you feel better (and you like needlessly complicating your code), you can do this:

os.path.join(dir_name, '.'.join((base_filename, filename_suffix)))

If you prefer to keep your code clean, simply include the dot in the suffix:

suffix = '.pdf'
os.path.join(dir_name, base_filename + suffix)

That approach also happens to be compatible with the suffix conventions in pathlib, which was introduced in python 3.4 after this question was asked. New code that doesn't require backward compatibility can do this:

suffix = '.pdf'
pathlib.PurePath(dir_name, base_filename + suffix)

You might prefer the shorter Path instead of PurePath if you're only handling paths for the local OS.

Warning: Do not use pathlib's with_suffix() for this purpose. That method will corrupt base_filename if it ever contains a dot.

Footnote: Outside of Micorsoft operating systems, there is no such thing as a file name "extension". Its presence on Windows comes from MS-DOS and FAT, which borrowed it from CP/M, which has been dead for decades. That dot-plus-three-letters that many of us are accustomed to seeing is just part of the file name on every other modern OS, where it has no built-in meaning.

I am not 100% sure this is what you want but if you are referring to the title bar (the little gray strip at the top), you can remove/customize it via your manifest.xml file...

<activity android:name=".activities.Main"
          android:theme="@android:style/Theme.NoTitleBar">

You don't have to do anything special, it should just be working.

When I have a fresh rails app with this controller:

class FooController < ApplicationController
  def index
    raise "error"
  end
end

and go to http://127.0.0.1:3000/foo/

I am seeing the exception with a stack trace.

You might not see the whole stacktrace in the console log because Rails (since 2.3) filters lines from the stack trace that come from the framework itself.

See config/initializers/backtrace_silencers.rb in your Rails project

If you put the declaration in a header file, and the definition in a separate .cpp file, and #include the header from a different .cpp file, you will be able to see the difference.

Specifically, suppose:

lib.h

int Add(int a, int b);

lib.cpp

int Add(int a, int b = 3) {
   ...
}

test.cpp

#include "lib.h"

int main() {
    Add(4);
}

The compilation of test.cpp will not see the default parameter declaration, and will fail with an error.

For this reason, the default parameter definition is usually specified in the function declaration:

lib.h

int Add(int a, int b = 3);

You seem to be confusing client-side and server side code. When the button is clicked you need to send (post, get) the variables to the server where the php can be executed. You can either submit the page or use an ajax call to submit just the data. -don

According to the go documentation, Unix returns a local time.

Unix returns the local Time corresponding to the given Unix time

This means the output would depend on the machine your code runs on, which, most often is what you need, but sometimes, you may want to have the value in UTC.

To do so, I adapted the snippet to make it return a time in UTC:

i, err := strconv.ParseInt("1405544146", 10, 64)
if err != nil {
    panic(err)
}
tm := time.Unix(i, 0)
fmt.Println(tm.UTC())

This prints on my machine (in CEST)

2014-07-16 20:55:46 +0000 UTC

For the replacement string and the replacement pattern as specified by $. here a resume:

link to doc : here

"hello _there_".replace(/_(.*?)_/g, "<div>$1</div>")

Note:

If you want to have a $ in the replacement string use $$. Same as with vscode snippet system.

If you aren't a fan of passing in a string, I prefer how @sesperanto has done it, except to make it even more concise, you could drop Float::INFINITY in the date range and instead simply use created_at: p[:date]..

Note.where(
    user_id: current_user.id,
    notetype: p[:note_type],
    created_at: p[:date]..
).order(:date, :created_at)

Take note that this will change the query to be >= instead of >. If that's a concern, you could always add a unit of time to the date by running something like p[:date] + 1.day..

There are three scenarios (that I can think of) where you would call a method in a subclass where the method exits in the parent class:

1. Method is not overwritten by subclass, only exists in parent.

   This is the same as your example, and generally it's better to use $this -> get_species(); You are right that in this case the two are effectively the same, but the method has been inherited by the subclass, so there is no reason to differentiate. By using $this you stay consistent between inherited methods and locally declared methods.

2. Method is overwritten by the subclass and has totally unique logic from the parent.

   In this case, you would obviously want to use $this -> get_species(); because you don't want the parent's version of the method executed. Again, by consistently using $this, you don't need to worry about the distinction between this case and the first.

3. Method extends parent class, adding on to what the parent method achieves.

   In this case, you still want to use `$this -> get_species(); when calling the method from other methods of the subclass. The one place you will call the parent method would be from the method that is overwriting the parent method. Example:

   abstract class Animal {
   
       function get_species() {
   
           echo "I am an animal.";
   
       }
   
    }
   
    class Dog extends Animal {
   
        function __construct(){
   
            $this->get_species();
        }
   
        function get_species(){
   
            parent::get_species();
            echo "More specifically, I am a dog.";
        }
   }
   

The only scenario I can imagine where you would need to call the parent method directly outside of the overriding method would be if they did two different things and you knew you needed the parent's version of the method, not the local. This shouldn't be the case, but if it did present itself, the clean way to approach this would be to create a new method with a name like get_parentSpecies() where all it does is call the parent method:

function get_parentSpecies(){

     parent::get_species();
}

Again, this keeps everything nice and consistent, allowing for changes/modifications to the local method rather than relying on the parent method.

In jsp you can do it like this:

<%
boolean checkboxDisabled = true; //do your logic here
String checkboxState = checkboxDisabled ? "disabled" : "";
%>
<input type="checkbox" <%=checkboxState%>>

Yeah, I'm using tf 2.0-beta and want to enable/disable the default logging. The environment variable and methods in tf1.X don't seem to exist anymore.

I stepped around in PDB and found this to work:

# close the TF2 logger
tf2logger = tf.get_logger()
tf2logger.error('Close TF2 logger handlers')
tf2logger.root.removeHandler(tf2logger.root.handlers[0])

I then add my own logger API (in this case file-based)

logtf = logging.getLogger('DST')
logtf.setLevel(logging.DEBUG)

# file handler
logfile='/tmp/tf_s.log'
fh = logging.FileHandler(logfile)
fh.setFormatter( logging.Formatter('fh %(asctime)s %(name)s %(filename)s:%(lineno)d :%(message)s') )
logtf.addHandler(fh)
logtf.info('writing to %s', logfile)

I would like to present another answer to this as the currently accepted answer doesn't work for me (I use LibreOffice). This solution should work in Excel, LibreOffice and OpenOffice:

First, insert a new row at the beginning of the sheet. Within that row, define the names you need:

Then, in the menu bar, go to View -> Freeze Cells -> Freeze First Row. It'll look like this now:

Now whenever you scroll down in the document, the first row will be "pinned" to the top:

To check that the file you're trying to open actually exists, you can change directories in terminal using cd. To change to ~/Desktop/sass/css: cd ~/Desktop/sass/css. To see what files are in the directory: ls.

If you want information about either of those commands, use the man page: man cd or man ls, for example.

Google for "basic unix command line commands" or similar; that will give you numerous examples of moving around, viewing files, etc in the command line.

On Mac OS X, you can also use open to open a finder window: open . will open the current directory in finder. (open ~/Desktop/sass/css will open the ~/Desktop/sass/css).

Instead of RenderViewToString I prefer a approach like

return Json(new { Url = Url.Action("Evil", model) });

then you can catch the result in your javascript and do something like

success: function(data) {
    $.post(data.Url, function(partial) { 
        $('#IdOfDivToUpdate').html(partial);
    });
}

I would simply use,

np.asarray(input, dtype=np.float)[0]

• If input is an ndarray of the right dtype, there is no overhead, since np.asarray does nothing in this case.
• if input is a list, np.asarray makes sure the output is of the right type.

Adding params keyword itself shows that you can pass multiple number of parameters while calling that method which is not possible without using it. To be more specific:

static public int addTwoEach(params int[] args)
{
    int sum = 0;

    foreach (var item in args)
    {
        sum += item + 2;
    }

    return sum;
}

When you will call above method you can call it by any of the following ways:

1. addTwoEach()
2. addTwoEach(1)
3. addTwoEach(new int[]{ 1, 2, 3, 4 })

But when you will remove params keyword only third way of the above given ways will work fine. For 1st and 2nd case you will get an error.

I would say change var sv = sel.options[sel.selectedIndex].value; to var sv = sel.options[sel.selectedIndex].text;

It worked for me. Directing you to where I found my solution Getting the selected value dropdown jstl

I'd use bootstrap and set the html as:

<div class="row">
    <div class="col-md-4">
        <img src="img/logo.png" alt="logo" />
    </div>
    <div class="col-md-8">
        <h1>My website name</h1>
    </div>
</div>

You can also use list.remove(a[0]) to pop out the first element in the list.

>>>> a=[1,2,3,4,5]
>>>> a.remove(a[0])
>>>> print a
>>>> [2,3,4,5]

Wow, the answers are all over the map. So the Documentation says:

A FOREIGN KEY constraint is a candidate for an index because:

• Changes to PRIMARY KEY constraints are checked with FOREIGN KEY constraints in related tables.

• Foreign key columns are often used in join criteria when the data from related tables is combined in queries by matching the column(s) in the FOREIGN KEY constraint of one table with the primary or unique key column(s) in the other table. An index allows Microsoft® SQL Server™ 2000 to find related data in the foreign key table quickly. However, creating this index is not a requirement. Data from two related tables can be combined even if no PRIMARY KEY or FOREIGN KEY constraints are defined between the tables, but a foreign key relationship between two tables indicates that the two tables have been optimized to be combined in a query that uses the keys as its criteria.

So it seems pretty clear (although the documentation is a bit muddled) that it does not in fact create an index.

It's easy. If you have two or more running container, complete next steps:

docker network create myNetwork
docker network connect myNetwork web1
docker network connect myNetwork web2

Now you connect from web1 to web2 container or the other way round.

Use the internal network IP addresses which you can find by running:

docker network inspect myNetwork

Note that only internal IP addresses and ports are accessible to the containers connected by the network bridge.

So for example assuming that web1 container was started with: docker run -p 80:8888 web1 (meaning that its server is running on port 8888 internally), and inspecting myNetwork shows that web1's IP is 172.0.0.2, you can connect from web2 to web1 using curl 172.0.0.2:8888).

if you need to decompile standalone jar try JD-GUI by the same autor (of JD-Eclipse). It is a standalone application (does not need eclipse). It can open both *.class and *.jar files. Interesting enough it needs .Net installed (as do JD-Eclipse indeed), but otherwise works like a charm.

Regards,

{ "date" : "1000000" } in your Mongo doc seems suspect. Since it's a number, it should be { date : 1000000 }

It's probably a type mismatch. Try post.findOne({date: "1000000"}, callback) and if that works, you have a typing issue.

All the answers so far given involve reading the file line by line, taking the line in as a String, and then processing the String.

There is no question that this is the easiest approach to understand, and if the file is fairly short (say, tens of thousands of lines), it'll also be acceptable in terms of efficiency. But if the file is long, it's a very inefficient way to do it, for two reasons:

1. Every character gets processed twice, once in constructing the String, and once in processing it.
2. The garbage collector will not be your friend if there are lots of lines in the file. You're constructing a new String for each line, and then throwing it away when you move to the next line. The garbage collector will eventually have to dispose of all these String objects that you don't want any more. Someone's got to clean up after you.

If you care about speed, you are much better off reading a block of data and then processing it byte by byte rather than line by line. Every time you come to the end of a number, you add it to the List you're building.

It will come out something like this:

private List<Integer> readIntegers(File file) throws IOException {
    List<Integer> result = new ArrayList<>();
    RandomAccessFile raf = new RandomAccessFile(file, "r");
    byte buf[] = new byte[16 * 1024];
    final FileChannel ch = raf.getChannel();
    int fileLength = (int) ch.size();
    final MappedByteBuffer mb = ch.map(FileChannel.MapMode.READ_ONLY, 0,
            fileLength);
    int acc = 0;
    while (mb.hasRemaining()) {
        int len = Math.min(mb.remaining(), buf.length);
        mb.get(buf, 0, len);
        for (int i = 0; i < len; i++)
            if ((buf[i] >= 48) && (buf[i] <= 57))
                acc = acc * 10 + buf[i] - 48;
            else {
                result.add(acc);
                acc = 0;
            }
    }
    ch.close();
    raf.close();
    return result;
}

The code above assumes that this is ASCII (though it could be easily tweaked for other encodings), and that anything that isn't a digit (in particular, a space or a newline) represents a boundary between digits. It also assumes that the file ends with a non-digit (in practice, that the last line ends with a newline), though, again, it could be tweaked to deal with the case where it doesn't.

It's much, much faster than any of the String-based approaches also given as answers to this question. There is a detailed investigation of a very similar issue in this question. You'll see there that there's the possibility of improving it still further if you want to go down the multi-threaded line.

This below code will give selected row, you can parse the values from it and send to the AJAX call.

$(".selected").click(function () {
var row = $(this).parent().parent().parent().html();            
});

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

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

Try simply to reset last commit using --soft flag

git reset --soft HEAD~1

Note :

For Windows, wrap the HEAD parts in quotes like git reset --soft "HEAD~1"

The official RFC which defines this specification could be found here:

You can use a common object and count the frequency of each value in the first array. For the second array, decrement the value in the common object. Then iterate through all keys and add all the keys whose values is more than 1.

const difference = (a1, a2) => {_x000D_
  var obj = {};_x000D_
  a1.forEach(v => obj[v] = (obj[v] || 0) + 1);_x000D_
  a2.forEach(v => obj[v] = (obj[v] || 0) - 1);_x000D_
  return Object_x000D_
      .keys(obj)_x000D_
      .reduce((r,k) => {_x000D_
        if(obj[k] > 0)_x000D_
          r = r.concat(Array.from({length: obj[k]}).fill(k));_x000D_
        return r;_x000D_

For security reasons most browsers do not allow to modify the clipboard (except IE, of course...).

The only way to make a copy-to-clipboard function cross-browser compatible is to use Flash.

Use ipdb

Install it via

pip install ipdb

Usage:

In[1]: def fun1(a):
   def fun2(a):
       import ipdb; ipdb.set_trace() # debugging starts here
       return do_some_thing_about(b)
   return fun2(a)
In[2]: fun1(1)

For executing line by line use n and for step into a function use s and to exit from debugging prompt use c.

Normally, it's considered poor style to unnecessarily cast pointers to (void*). Here, however, you need the casts to (void*) on the printf arguments because printf is variadic. The prototype doesn't tell the compiler what type to convert the pointers to at the call site.

You cant run PHP when a user clicks on a link without leaving the page unless you use AJAX. PHP is a serverside scripting language, meaning the second that the browser sees the page, there is no PHP in it.

Unlike Javascript, PHP is ran completely on the server, and browser wouldn't know how to interpret it if it bit them on the rear. The only way to invoke PHP code is to make a Page request, by either refreshing the page, or using javascript to go fetch a page.

In an AJAX Solution, basically the page uses javascript to send a page request to another page on your domain. Javascript then gets whatever you decide to echo in the response, and it can parse it and do what it wants from there. When you are creating the response, you can also do any backend stuff like updating databases.

In case you happen to be using Spring framework along with java, there is an easy way around.

1. Import the following.

   import org.springframework.util.Base64Utils;

2. Convert like this.

   byte[] bytearr ={0,1,2,3,4};
   String encodedText = Base64Utils.encodeToString(bytearr);
   

   To decode you can use the decodeToString method of the Base64Utils class.

There's 3 satellites at least that you must be able to receive from of the 24-32 out there, and they each broadcast a time from a synchronized atomic clock. The differences in those times that you receive at any one time tell you how long the broadcast took to reach you, and thus where you are in relation to the satellites. So, it sort of reads from something, but it doesn't connect to that thing. Note that this doesn't tell you your orientation, many GPSes fake that (and speed) by interpolating data points.

If you don't count the cost of the receiver, it's a free service. Apparently there's higher resolution services out there that are restricted to military use. Those are likely a fixed cost for a license to decrypt the signals along with a confidentiality agreement.

Now your device may support GPS tracking, in which case it might communicate, say via GPRS, to a database which will store the location the device has found itself to be at, so that multiple devices may be tracked. That would require some kind of connection.

Maps are either stored on the device or received over a connection. Navigation is computed based on those maps' databases. These likely are a licensed item with a cost associated, though if you use a service like Google Maps they have the license with NAVTEQ and others.

This covers empty Array and empty Object also

null, undefined, ' ', 0, [ ], { }

isEmpty = (value) => (!value  || (typeof v === 'object' &&
   Object.keys(value).length < 1));

First, see if you have splitunc() as an available function within os.path. The first item returned should be what you want... but I am on Linux and I do not have this function when I import os and try to use it.

Otherwise, one semi-ugly way that gets the job done is to use:

>>> pathname = "\\C:\\mystuff\\project\\file.py"
>>> pathname
'\\C:\\mystuff\\project\\file.py'
>>> print pathname
\C:\mystuff\project\file.py
>>> "\\".join(pathname.split('\\')[:-2])
'\\C:\\mystuff'
>>> "\\".join(pathname.split('\\')[:-1])
'\\C:\\mystuff\\project'

which shows retrieving the directory just above the file, and the directory just above that.

Use the DATEDIFF() function.

Example from documentation:

SELECT DATEDIFF('2007-12-31 23:59:59','2007-12-30');
    -> 1

Use the oncontextmenu event.

Here's an example:

<div oncontextmenu="javascript:alert('success!');return false;">
    Lorem Ipsum
</div>

And using event listeners (credit to rampion from a comment in 2011):

el.addEventListener('contextmenu', function(ev) {
    ev.preventDefault();
    alert('success!');
    return false;
}, false);

Don't forget to return false, otherwise the standard context menu will still pop up.

If you are going to use a function you've written rather than javascript:alert("Success!"), remember to return false in BOTH the function AND the oncontextmenu attribute.

Use

if (Build.VERSION.SDK_INT >= 19) {
        mWebView.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
    }

It should solve the error.

Why do you want to do that?

However, You can do this:

public void foo(int param1)
{
    int param2 = 2;
    // rest of code
}

or:

public void foo(int param1, int param2)
{
    // rest of code
}

public void foo(int param1)
{
    foo(param1, 2);
}

you can try to reinstall the latest version of xcode / dev. tools for snow leopard - this should fix your errors

Current state: default implementation in docs

Currently there is a default implementation of input+dropdown combo in the documentation here (search for "Button dropdowns"). I leave the original solution for the record and for those who cannot use solution now included in the documentation.

Original solution

Yes, it is possible. As a matter of fact, there is one example in the Twitter Bootstrap documentation (follow the link and search "Examples" for dropdown buttons):

<div class="btn-group">
    <a class="btn btn-primary" href="#">
        <i class="icon-user icon-white"></i> User
    </a>
    <a class="btn btn-primary dropdown-toggle" data-toggle="dropdown" href="#">
        <span class="caret"></span>
    </a>
    <ul class="dropdown-menu">
        <li><a href="#"><i class="icon-pencil"></i> Edit</a></li>
        <li><a href="#"><i class="icon-trash"></i> Delete</a></li>
        <li><a href="#"><i class="icon-ban-circle"></i> Ban</a></li>
        <li class="divider"></li>
        <li><a href="#"><i class="i"></i> Make admin</a></li>
    </ul>
</div>

If enclosed within text, it can look like this (with text on the button changed, nothing else):

EDIT:

If you are trying to achieve <input> with appended dropdown menu as in the dropdown buttons, then this is one of the solutions:

1. Add a btn-group class to the element that has input-append class,
2. Add elements with classes dropdown-toggle and dropdown-menu at the end of the element with class input-append,
3. Override style for element matching .input-append .btn.dropdown-menu so it does not have float: left (otherwise it will get into next line).

The resulting code may look like this:

<div class="input-append btn-group">
    <input class="span2" id="appendedInputButton" size="16" type="text">
    <a class="btn btn-primary dropdown-toggle" data-toggle="dropdown" href="#">
        <span class="caret"></span>
    </a>
    <ul class="dropdown-menu">
        <li><a href="#"><i class="icon-pencil"></i> Edit</a></li>
        <li><a href="#"><i class="icon-trash"></i> Delete</a></li>
        <li><a href="#"><i class="icon-ban-circle"></i> Ban</a></li>
        <li class="divider"></li>
        <li><a href="#"><i class="i"></i> Make admin</a></li>
    </ul>
</div>

with a little support from this style override:

.input-append .btn.dropdown-toggle {
    float: none;
}

and give you the exact same result as this:

EDIT 2: Updated the CSS selector (was .dropdown-menu, is .dropdown-toggle).

It means somewhere in your chain of calls, you tried to access a Property or call a method on an object that was null.

Given your statement:

img1.ImageUrl = ConfigurationManager
                    .AppSettings
                    .Get("Url")
                    .Replace("###", randomString) 
                + Server.UrlEncode(
                      ((System.Web.UI.MobileControls.Form)Page
                      .FindControl("mobileForm"))
                      .Title);

I'm guessing either the call to AppSettings.Get("Url") is returning null because the value isn't found or the call to Page.FindControl("mobileForm") is returning null because the control isn't found.

You could easily break this out into multiple statements to solve the problem:

var configUrl = ConfigurationManager.AppSettings.Get("Url");
var mobileFormControl = Page.FindControl("mobileForm")
                            as System.Web.UI.MobileControls.Form;

if(configUrl != null && mobileFormControl != null)
{
    img1.ImageUrl = configUrl.Replace("###", randomString) + mobileControl.Title;
}

The problem was the notify filters. The program was trying to open a file that was still copying. I removed all of the notify filters except for LastWrite.

private void watch()
{
  FileSystemWatcher watcher = new FileSystemWatcher();
  watcher.Path = path;
  watcher.NotifyFilter = NotifyFilters.LastWrite;
  watcher.Filter = "*.*";
  watcher.Changed += new FileSystemEventHandler(OnChanged);
  watcher.EnableRaisingEvents = true;
}

Here is code for reading a matrix, note you also have a csvwrite function in matlab

void loadFromCSV( const std::string& filename )
{
    std::ifstream       file( filename.c_str() );
    std::vector< std::vector<std::string> >   matrix;
    std::vector<std::string>   row;
    std::string                line;
    std::string                cell;

    while( file )
    {
        std::getline(file,line);
        std::stringstream lineStream(line);
        row.clear();

        while( std::getline( lineStream, cell, ',' ) )
            row.push_back( cell );

        if( !row.empty() )
            matrix.push_back( row );
    }

    for( int i=0; i<int(matrix.size()); i++ )
    {
        for( int j=0; j<int(matrix[i].size()); j++ )
            std::cout << matrix[i][j] << " ";

        std::cout << std::endl;
    }
}

I think it's worth showing the difference between the various options mentioned - often a picture is worth a thousand words.

To summarize:

• vars() and __dict__ only return instance-local properties;
• dir() returns everything, but only as a list of string member names; dynamic properties are not called;
• inspect.getmembers() returns everything, as a list of tuples (name, value); it actually runs dynamic properties, and accepts an optional predicate argument that can filter out members by value.

So my common-sense approach is typically to use dir() on the command line, and getmembers() in programs, unless specific performance considerations apply.

Note that, to keep things cleaner, I did not include __slots__ - if present, it was explicitly put there to be queried, and should be used directly. I also did not cover metaclasses, which can get a bit hairy (most people will never use them anyway).

This answer works for latest update on Windows 10 version 1709. Not tried with other version. But i hope it'll work.

I also ran into similar issue in my windows 10 system. I disabled Hyper-V and I tried all the answers posted here. But after that also i faced the same issue. So after lot of try, made it work using an documentation available in haxm manual. The document menntioned to use a tool named Device Guard and Credential Guard hardware readiness tool provided by Microsoft to disable Hyper-V along with some other features(Remember not only Hyper-V. So little cautios) completely. Follow the below steps to do that.

1. Download the latest version of the tool from here.
2. Unzip.
3. Open an elevated (i.e. Run as administrator) Command Prompt and run the below command by changing the extrated path and the respective version number.

@powershell -ExecutionPolicy RemoteSigned -Command "X:\path\to\dgreadiness_v3.6\DG_Readiness_Tool_v3.6.ps1 -Disable"

4. Reboot.

Then if you try to install intel haxm, it'll work.

In case of latest update check the docs available in official intel haxm development link.

Hope it helps someone.

Check bmon. It's cli, simple and has charts.

ssh-keygen -p -m PEM -f ~/.ssh/id_rsa

Use the onfocus and onblur events like this:

<input type="text" name="yourName" value="A new value" onfocus="if (this.value == 'A new value') this.value = '';" onblur="if (this.value == '') this.value = 'A new value';">

Hey I was facing this issue with my react-native bare project, the IOS simulator works fine but android kept giving me this error. here is a possible solution which has worked for me.

step 1, check if the adb device is authorized by running in your terminal : adb devices

if it is unauthorised run the following commands

step 2, sudo adb kill-server step 3, sudo adb start-server

then check if the adb devices command shows list of devices attached emulator-5554 device

instead of unauthorized if it is device instead of unauthorized

step 4, run npx react-native run-android

this has worked in my instance.

When you are in the shell directory for the device. Just run

su - root

Then you should be able to access the data/ folder.

spans default to inline style, which you can't specify the width of.

display: inline-block;

would be a good way, except IE doesn't support it

you can, however, hack a multiple browser solution

The bootstrap docs do explain it, but it still took me a while to get it. It makes more sense when I explain it to myself in one of two ways:

If you think of the columns starting out horizontally, then you can choose when you want them to stack.

For example, if you start with columns: A B C

You decide when should they stack to be like this:

A

B

C

If you choose col-lg, then the columns will stack when the width is < 1200px.

If you choose col-md, then the columns will stack when the width is < 992px.

If you choose col-sm, then the columns will stack when the width is < 768px.

If you choose col-xs, then the columns will never stack.

On the other hand, if you think of the columns starting out stacked, then you can choose at what point they become horizontal:

If you choose col-sm, then the columns will become horizontal when the width is >= 768px.

If you choose col-md, then the columns will become horizontal when the width is >= 992px.

If you choose col-lg, then the columns will become horizontal when the width is >= 1200px.

Suppose your program doesn't have memory leakage, objects accumulates and cannot be GC-ed in Gen 0 because: 1) They are referenced for long time so get into Gen1 & Gen2; 2) They are large objects (>80K) so get into LOH (Large Object Heap). And LOH doesn't do compacting as in Gen0, Gen1 & Gen2.

Check the performance counter of ".NET Memory" can you can see that the 1) problem is really not a problem. Generally, every 10 Gen0 GC will trigger 1 Gen1 GC, and every 10 Gen1 GC will trigger 1 Gen2 GC. Theoretically, GC1 & GC2 can never be GC-ed if there is no pressure on GC0 (if the program memory usage is really wired). It never happens to me.

For problem 2), you can check ".NET Memory" performance counter to verify whether LOH is getting bloated. If it is really a issue to your problem, perhaps you can create a large-object-pool as this blog suggests http://blogs.msdn.com/yunjin/archive/2004/01/27/63642.aspx.

PHP has a method called md5 ;-) Just $password = md5($passToEncrypt);

If you are searching in a SQL u can use a MySQL Method MD5() too....

 SELECT * FROM user WHERE Password='. md5($password) .'

or SELECT * FROM ser WHERE Password=MD5('. $password .')

To insert it u can do it the same way.

This answer is actually taken from Scott Allen's course titled ASP.NET MVC 5 Fundamentals. I thought I'd share because I think it is slightly simpler and more intuitive than any of the answers here already. Also note according to Scott Allen and other trainings I've done, find method is an optimized way to retrieve a resource from database that can use caching if it already has been retrieved. In this code, collection refers to a DBSet of objects. Object can be any generic object type.

        var object = context.collection.Find(id);  
        context.collection.Remove(object);
        context.SaveChanges();

You could simply use .rounded-circle bootstrap.

 <img class="rounded-circle" src="http://placekitten.com/g/200/200"/>

You can even specify the width and height of the rounded image by providing an inline style to the image, which overrides the default size.

 <img class="rounded-circle" style="height:100px; width: 100px" src="http://placekitten.com/g/200/200" />

One way to partially get around the problem is to use the API Level suffix. I use res/layout-v1, res/layout-v2 etc to hold multiple sub projects in the same apk. This mechanism can be used for all resource types.

Obviously, this can only be used if you are targeting API levels above the res/layout-v? you are using.

Also, watch out for the bug in Android 1.5 and 1.6. See Andoroid documentation about the API Level suffix.

The syntax to disable an HTML input is as follows:

<input type="text" id="input_id" DISABLED />

>>> a = 147.234
>>> a % 1
0.23400000000000887
>>> a // 1
147.0
>>>

If you want the integer part as an integer and not a float, use int(a//1) instead. To obtain the tuple in a single passage: (int(a//1), a%1)

EDIT: Remember that the decimal part of a float number is approximate, so if you want to represent it as a human would do, you need to use the decimal library

Scope means the code context that performs the INSERT statement SCOPE_IDENTITY(), as opposed to the global scope of @@IDENTITY.

CREATE TABLE Foo(
  ID INT IDENTITY(1,1),
  Dummy VARCHAR(100)
)

CREATE TABLE FooLog(
  ID INT IDENTITY(2,2),
  LogText VARCHAR(100)
)
go
CREATE TRIGGER InsertFoo ON Foo AFTER INSERT AS
BEGIN
  INSERT INTO FooLog (LogText) VALUES ('inserted Foo')
  INSERT INTO FooLog (LogText) SELECT Dummy FROM inserted
END

INSERT INTO Foo (Dummy) VALUES ('x')
SELECT SCOPE_IDENTITY(), @@IDENTITY 

Gives different results.

item=sp.getItemAtPosition(i).toString();
list.add(item);
adapter.notifyDataSetChanged () ;

look up ArrayAdapter.notifyDataSetChanged()

Access-Control-Allow-Headers does not allow * as accepted value, see the Mozilla Documentation here.

Instead of the asterisk, you should send the accepted headers (first X-Requested-With as the error says).

While its not bad practice to use break and there are many excellent uses for it, it should not be all you rely upon. Almost any use of a break can be written into the loop condition. Code is far more readable when real conditions are used, but in the case of a long-running or infinite loop, breaks make perfect sense. They also make sense when searching for data, as shown above.

Your root logger definition is a bit confused. See the log4j documentation.

This is a standard Java properties file, which means that lines are treated as key=value pairs. Your second log4j.rootLogger line is overwriting the first, which explains why you aren't seeing anything on the console appender.

You need to merge your two rootLogger definitions into one. It looks like you're trying to have DEBUG messages go to the console and INFO messages to the file. The root logger can only have one level, so you need to change your configuration so that the appenders have appropriate levels.

While I haven't verified that this is correct, I'd guess it'll look something like this:

log4j.rootLogger=DEBUG,console,file
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.file=org.apache.log4j.RollingFileAppender

Note that you also have an error in casing - you have console lowercase in one place and in CAPS in another.

real-time - Pertaining to a system or mode of operation in which computation is performed during the actual time that an external process occurs, in order that the computation results can be used to control, monitor, or respond to the external process in a timely manner. [IEEE Standard 610.12.1990]

I know this definition is old, very old. I can't, however, find a more recent definition by the IEEE (Institute of Electrical and Electronics Engineers).

This problem is happend because of php.ini defined limit was exided but have lot's of solution for this but simple one is to find your local servers folder and on that find the php folder and in that folder have php.ini file which have all declaration of these type setups. You just need to find one and change that value. But in this situation have one big problem once you change in your localhost file but what about server when you want to put your site on server it again produce same problem and you again follow the same for server. But you also know about .htaccess file this is one of the best and single place to do a lot's of things without changing core files. Like you change www routing, removing .php or other extentions from url or add one. Same like that you also difine default values of php.ini here like this - First you need to open the .htaccess file from your root directory or if you don't have this file so create one on root directory of your site and paste this code on it -

php_value upload_max_filesize 1000M
php_value post_max_size 99500M
php_value memory_limit 500M
php_value max_execution_time 300

after changes if you want to check the changes just run the php code

<?php phpinfo(); ?> 

it will show you the php cofigrations all details. So you find your changes.

Note: for defining unlimited just add -1 like php_value memory_limit -1 It's not good and most of the time slow down your server. But if you like to be limit less then this one option is also fit for you. If after refresh your page changes will not reflect you must restart your local server once for changes.

Good Luck. Hope it will help. Want to download the .htaccess file click this.

If you see question marks in the file or if the accents are already lost, going back to utf8 will not help your cause. e.g. if café became cafe - changing encoding alone will not help (and you'll need original data).

Can you paste some text here, that'll help us answer for sure.

Had the same issue and just figured, website is running under MAMP's php, but when you call in command, it runs mac's(if no bash path modified). you will have issue when mac doesn't have those extensions.

run php -i to find out loaded extensions, and install those one you missed. or run '/Applications/MAMP/bin/php/php5.3.6/bin/php artisan {your command}' to use MAMP's

This issue is one of language philosophy. In Java for example there has always been a tradition that exceptions should really only be used in "exceptional circumstances" that is when errors have happened, rather than for flow control. In the beginning this was for performance reasons as Java exceptions were slow but now this has become the accepted style.

In contrast Python has always used exceptions to indicate normal program flow, like raising a ValueError as we are discussing here. There is nothing "dirty" about this in Python style and there are many more where that came from. An even more common example is StopIteration exception which is raised by an iterator‘s next() method to signal that there are no further values.

Your model is @Messages, change it to @message.

To change it like you should use migration:

def change   rename_table :old_table_name, :new_table_name end 

Of course do not create that file by hand but use rails generator:

rails g migration ChangeMessagesToMessage 

That will generate new file with proper timestamp in name in 'db dir. Then run:

rake db:migrate 

And your app should be fine since then.

to upload a file using curl in Windows I found that the path requires escaped double quotes

e.g.

curl -v -F 'upload=@\"C:/myfile.txt\"' URL

Instead of using a <text> tag, the <foreignObject> tag can be used, which allows for XHTML content with CSS.

For people that want to response according to http status code, you can use the ErrorController way:

@Controller
public class CustomErrorController extends BasicErrorController {

    public CustomErrorController(ServerProperties serverProperties) {
        super(new DefaultErrorAttributes(), serverProperties.getError());
    }

    @Override
    public ResponseEntity error(HttpServletRequest request) {
        HttpStatus status = getStatus(request);
        if (status.equals(HttpStatus.INTERNAL_SERVER_ERROR)){
            return ResponseEntity.status(status).body(ResponseBean.SERVER_ERROR);
        }else if (status.equals(HttpStatus.BAD_REQUEST)){
            return ResponseEntity.status(status).body(ResponseBean.BAD_REQUEST);
        }
        return super.error(request);
    }
}

The ResponseBean here is my custom pojo for response.

Just to play with it, question is strong entity type and answer is weak. Question is always there, but an answer requires a question to exist.

Example: Don't ask 'Why?' if Your Dad's a Chemistry Professor

Any Image is a collection of signals of various frequencies. The higher frequencies control the edges and the lower frequencies control the image content. Edges are formed when there is a sharp transition from one pixel value to the other pixel value like 0 and 255 in adjacent cell. Obviously there is a sharp change and hence the edge and high frequency. For sharpening an image these transitions can be enhanced further.

One way is to convolve a self made filter kernel with the image.

    import cv2
    import numpy as np

    image = cv2.imread('images/input.jpg')
    kernel = np.array([[-1,-1,-1], 
                       [-1, 9,-1],
                       [-1,-1,-1]])
    sharpened = cv2.filter2D(image, -1, kernel) # applying the sharpening kernel to the input image & displaying it.
    cv2.imshow('Image Sharpening', sharpened)
    cv2.waitKey(0)
    cv2.destroyAllWindows()

There is another method of subtracting a blurred version of image from bright version of it. This helps sharpening the image. But should be done with caution as we are just increasing the pixel values. Imagine a grayscale pixel value 190, which if multiplied by a weight of 2 makes if 380, but is trimmed of at 255 due to the maximum allowable pixel range. This is information loss and leads to washed out image.

    addWeighted(frame, 1.5, image, -0.5, 0, image);

Here are a few options for changing text / label sizes

library(ggplot2)

# Example data using mtcars

a <- aggregate(mpg ~ vs + am , mtcars, function(i) round(mean(i)))

p <- ggplot(mtcars, aes(factor(vs), y=mpg, fill=factor(am))) + 
            geom_bar(stat="identity",position="dodge") + 
            geom_text(data = a, aes(label = mpg), 
                            position = position_dodge(width=0.9),  size=20)

The size in the geom_text changes the size of the geom_text labels.

p <- p + theme(axis.text = element_text(size = 15)) # changes axis labels

p <- p + theme(axis.title = element_text(size = 25)) # change axis titles

p <- p + theme(text = element_text(size = 10)) # this will change all text size 
                                                             # (except geom_text)

For this And why size of 10 in geom_text() is different from that in theme(text=element_text()) ?

Yes, they are different. I did a quick manual check and they appear to be in the ratio of ~ (14/5) for geom_text sizes to theme sizes.

So a horrible fix for uniform sizes is to scale by this ratio

geom.text.size = 7
theme.size = (14/5) * geom.text.size

ggplot(mtcars, aes(factor(vs), y=mpg, fill=factor(am))) + 
  geom_bar(stat="identity",position="dodge") + 
  geom_text(data = a, aes(label = mpg), 
            position = position_dodge(width=0.9),  size=geom.text.size) + 
  theme(axis.text = element_text(size = theme.size, colour="black")) 

This of course doesn't explain why? and is a pita (and i assume there is a more sensible way to do this)

context.getPackageManager().getInstalledApplications(PackageManager.GET_META_DATA); Should return the list of all the installed apps but in android 11 it'll only return the list of system apps. To get the list of all the applications(system+user) we need to provide an additional permission to the application i.e

<uses-permission android:name"android.permission.QUERY_ALL_PACKAGES">

I had the same issue. Tried all the solutions mentioned here but nothing worked. So i rebooted my device and suddenly the issue solved.

You can try this

$("#target").prop("selectedIndex", 0);

As far as I am concerned, I prefer to externalize the error messages in a properties files. This will be really helpful in case of internationalization of your application (one properties file per language). It is also easier to modify an error message, and it won't need any re-compilation of the Java sources.

On my projects, generally I have an interface that contains errors codes (String or integer, it doesn't care much), which contains the key in the properties files for this error:

public interface ErrorCodes {
    String DATABASE_ERROR = "DATABASE_ERROR";
    String DUPLICATE_USER = "DUPLICATE_USER";
    ...
}

in the properties file:

DATABASE_ERROR=An error occurred in the database.
DUPLICATE_USER=The user already exists.
...

Another problem with your solution is the maintenability: you have only 2 errors, and already 12 lines of code. So imagine your Enumeration file when you will have hundreds of errors to manage!

Try this scenario:

Array = A1:C7. A1-A3 have values, B2-B6 have value and C1, C3 and C6 have values.

To get a count of the number of rows add a column D (you can hide it after formulas are set up) and in D1 put formula =If(Sum(A1:C1)>0,1,0). Copy the formula from D1 through D7 (for others searching who are not excel literate, the numbers in the sum formula will change to the row you are on and this is fine).

Now in C8 make a sum formula that adds up the D column and the answer should be 6. For visually pleasing purposes hide column D.

As the other answers say, use g++ instead of gcc.

Or use make: make hi

If you want avoid the "abortInError false" option, take a look at build/lint-results-release-fatal.html file. Here are the erros detected by lint.

I hope this can help somebody!

$id = $access_data['Privilege']['id']; 

if(!in_array($id,$user_access_arr));
    $user_access_arr[] = $id;
    $this->Session->setFlash(__('Access Denied! You are not eligible to access this.'), 'flash_custom_success');
    return $this->redirect(array('controller'=>'Dashboard','action'=>'index'));

Watch out for lots of incorrect answers to this question!

Gerard's logic is correct, though it will return a list rather than a queryset (which might not matter).

If you need a queryset, use Q:

from django.db.models import Q
results = Model.objects.filter(Q(a=false) | Q(x=5))

A short summary from my humble knowledge:

There are some easy computational problems (like finding the shortest path between two points in a graph), which can be calculated pretty fast ( O(n^k), where n is the size of the input and k is a constant (in the case of graphs, it's the number of vertexes or edges)).

Other problems, like finding a path that crosses every vertex in a graph or getting the RSA private key from the public key is harder (O(e^n)).

But CS speak tells that the problem is that we cannot 'convert' a non-deterministic Turing-machine to a deterministic one, we can, however, transform non-deterministic finite automatons (like the regex parser) into deterministic ones (well, you can, but the run-time of the machine will take long). That is, we have to try every possible path (usually smart CS professors can exclude a few ones).

It's interesting because nobody even has any idea of the solution. Some say it's true, some say it's false, but there is no consensus. Another interesting thing is that a solution would be harmful for public/private key encryptions (like RSA). You could break them as easily as generating an RSA key is now.

And it's a pretty inspiring problem.

Pretty late and not sure if this was available when the question was asked, set width: auto;

Seems to do the trick

You can use Modernizr to detect simply IE or not IE, by checking for SVG SMIL animation support.

If you've included SMIL feature detection in your Modernizr setup, you can use a simple CSS approach, and target the .no-smil class that Modernizr applies to the html element:

html.no-smil {
  /* IE/Edge specific styles go here - hide HTML5 content and show Flash content */
}

Alternatively, you could use Modernizr with a simple JavaScript approach, like so:

if ( Modernizr.smil ) {
  /* set HTML5 content */
} else {
  /* set IE/Edge/Flash content */
}

Bear in mind, IE/Edge might someday support SMIL, but there are currently no plans to do so.

For reference, here's a link to the SMIL compatibility chart at caniuse.com.

Your friend is correct. Both gzip and ZIP are based on DEFLATE. This is a general purpose algorithm, and is not intended for encoding small strings.

If you need this, a possible solution is a custom encoding and decoding HashMap<String, String>. This can allow you to do a simple one-to-one mapping:

HashMap<String, String> toCompressed, toUncompressed;

String compressed = toCompressed.get(uncompressed);
// ...
String uncompressed = toUncompressed.get(compressed);

Clearly, this requires setup, and is only practical for a small number of strings.

This command works for me:

Command:

mysql --host=localhost -uroot -proot

The null character '\0' (also null terminator), abbreviated NUL, is a control character with the value zero. Its the same in C and objective C

The character has much more significance in C and it serves as a reserved character used to signify the end of a string,often called a null-terminated string

The length of a C string (an array containing the characters and terminated with a '\0' character) is found by searching for the (first) NUL byte.

Strange.

If it can't find explorer.exe, you should get an exception. If it can't find the folder, it should still open some folder (eg my Documents)

You say another copy of Explorer appears in the taskmanager, but you can't see it.

Is it possible that it is opening offscreen (ie another monitor)?

Or are you by any chance doing this in a non-interactive service?

In my case it was a permission issue. I had to:

• chmod a+wrx the image,

then it worked.

A variable is final or effectively final when it's initialized once and it's never mutated in its owner class. And we can't initialize it in loops or inner classes.

Final:

final int number;
number = 23;

Effectively Final:

int number;
number = 34;

Note: Final and Effective Final are similar(Their value don't change after assignment) but just that effective Final variables are not declared with Keyword final.

You possibly do not have create permissions to the folder. So WinSCP fails to create a temporary file for the transfer.

You have two options:

• Grant write permissions to the folder to the user or group you log in with (myuser), or change the ownership of the folder to the user, or

• Disable a transfer to temporary file.

  In Preferences, go to Transfer > Endurance page and in Enable transfer resume/transfer to temporary file name for select Disable:

  

bin/kafka-topics.sh –delete –zookeeper localhost:2181 –topic <topic-name>

You can remove the "not null" property from your column in mysql table if not necessary. when you remove "not null" property no need for "0000-00-00 00:00:00" conversion and problem is gone.

At least worked for me.

em is basically CSS property for font sizes.

The em and ex units depend on the font and may be different for each element in the document. The em is simply the font size. In an element with a 2in font, 1em thus means 2in. Expressing sizes, such as margins and paddings, in em means they are related to the font size, and if the user has a big font (e.g., on a big screen) or a small font (e.g., on a handheld device), the sizes will be in proportion. Declarations such as text-indent: 1.5em and margin: 1em are extremely common in CSS.

Instead of trying to stop the onCreate() from being fired altogether, maybe try checking the Bundle savedInstanceState being passed into the event to see if it is null or not.

For instance, if I have some logic that should be run when the Activity is truly created, not on every orientation change, I only run that logic in the onCreate() only if the savedInstanceState is null.

Otherwise, I still want the layout to redraw properly for the orientation.

public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_game_list);

        if(savedInstanceState == null){
            setupCloudMessaging();
        }
}

not sure if this is the ultimate answer, but it works for me.

i guess it is so obvious now that no one has posted this but for the noobs.... note: iPhone 4S only

just airplay to an apple tv and video mirror then output the atv to a device that can record - like tivo, dvr etc. you can also use a video out cable on the iPad [1 and 2] now

not sure if the cable works on the iPhone 4S as I havent tested that myself

its clunky but there is no other way i can see atm.

If you are still having issues, try running these steps from VMware to disable credential guard. Worked for me, finally. Steps and link are posted below, not taking credit for them.

Original content from https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2146361

To disable Device Guard or Credential Guard on Itanium based computers:

1. Disable the group policy setting that was used to enable Credential Guard.

   On the host operating system, click Start > Run, type gpedit.msc, and click Ok. The Local group Policy Editor opens.

   Go to Local Computer Policy > Computer Configuration > Administrative Templates > System > Device Guard > Turn on Virtualization Based Security.

   Select Disabled.

2. Go to Control Panel > Programs and Features > Turn Windows features on or off to turn off Hyper-V. [ remove a program on Windows 8 or earlier]

3. Select Do not restart.

4. Delete the related EFI variables by launching a command prompt on the host machine using an Administrator account and run these commands:

   enter code here

   mountvol X: /s

   copy %WINDIR%\System32\SecConfig.efi X:\EFI\Microsoft\Boot\SecConfig.efi /Y

   bcdedit /create {0cb3b571-2f2e-4343-a879-d86a476d7215} /d "DebugTool" /application osloader

   bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} path "\EFI\Microsoft\Boot\SecConfig.efi"

   bcdedit /set {bootmgr} bootsequence {0cb3b571-2f2e-4343-a879-d86a476d7215}

   bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} loadoptions DISABLE-LSA-ISO,DISABLE-VBS

   bcdedit /set {0cb3b571-2f2e-4343-a879-d86a476d7215} device partition=X:

   mountvol X: /d

Note: Ensure X is an unused drive, else change to another drive.

5. Restart the host.

6. Accept the prompt on the boot screen to disable Device Guard or Credential Guard.

You should be able to install and start HAXM now

1) Change the extension to properties (ex. mybundle.properties.)
2) Put your file into a jar and add it to your classpath.
3) Access the properties using this code:

ResourceBundle rb = ResourceBundle.getBundle("mybundle");
String propertyValue = rb.getString("key");

The docs explicitly says that java.sql.Date will throw:

• IllegalArgumentException - if the date given is not in the JDBC date escape format (yyyy-[m]m-[d]d)

Also you shouldn't need to convert a date to a String then to a sql.date, this seems superfluous (and bug-prone!). Instead you could:

java.sql.Date sqlDate := new java.sql.Date(now.getTime());
prs.setDate(2, sqlDate);
prs.setDate(3, sqlDate);

py -m pip install numpy

Worked for me!

There is nothing to fix. You simply have made 3 commits and haven't moved them to the remote branch yet. There are several options, depending on what you want to do:

• git push: move your changes to the remote (this might get rejected if there are already other changes on the remote)
• do nothing and keep coding, sync another day
• git pull: get the changes (if any) from the remote and merge them into your changes
• git pull --rebase: as above, but try to redo your commits on top of the remote changes

You are in a classical situation (although usually you wouldn't commit a lot on master in most workflows). Here is what I would normally do: Review my changes. Maybe do a git rebase --interactive to do some cosmetics on them, drop the ones that suck, reorder them to make them more logical. Now move them to the remote with git push. If this gets rejected because my local branch is not up to date: git pull --rebase to redo my work on top of the most recent changes and git push again.

See ?boxplot for all the help you need.

 outline: if ‘outline’ is not true, the outliers are not drawn (as
          points whereas S+ uses lines).

boxplot(x,horizontal=TRUE,axes=FALSE,outline=FALSE)

And for extending the range of the whiskers and suppressing the outliers inside this range:

   range: this determines how far the plot whiskers extend out from the
          box.  If ‘range’ is positive, the whiskers extend to the most
          extreme data point which is no more than ‘range’ times the
          interquartile range from the box. A value of zero causes the
          whiskers to extend to the data extremes.

# change the value of range to change the whisker length
boxplot(x,horizontal=TRUE,axes=FALSE,range=2)

Something like this has just happened to me...

I wrote:

{response.isDisplayOptions &&
{element}
}

Placing it inside a div fixed it:

{response.isDisplayOptions &&
    <div>
        {element}
    </div>
}

Now there is a problem, if you have package-lock.json with npm 5+. You have to remove it before use of npm install --production.

For me none of the solution above worked. Below is what i did to resolve the issue: modify the value using this function in the PHP code:

$value = utf8_encode($value);

This output values properly in an excel sheet.

As there's already an existing repository, running

git config --bool core.bare true

on the remote repository should suffice

From the core.bare documentation

If true (bare = true), the repository is assumed to be bare with no working directory associated. If this is the case a number of commands that require a working directory will be disabled, such as git-add or git-merge (but you will be able to push to it).

This setting is automatically guessed by git-clone or git-init when the repository is created. By default a repository that ends in "/.git" is assumed to be not bare (bare = false), while all other repositories are assumed to be bare (bare = true).

You can do it in CSS, but there isn't much support in browsers other than modern versions of Chrome, Safari and Opera at the moment. Firefox currently only supports SVG masks. See the Caniuse results for more information.

CSS:

p {
    color: red;
    -webkit-mask-image: -webkit-gradient(linear, left top, left bottom, 
    from(rgba(0,0,0,1)), to(rgba(0,0,0,0)));
}

The trick is to specify a mask that is itself a gradient that ends as invisible (thru alpha value)

See a demo with a solid background, but you can change this to whatever you want.

DEMO

Notice also that all the usual image properties are available for mask-image

p  {_x000D_
  color: red;_x000D_
  font-size: 30px;_x000D_
  -webkit-mask-image: linear-gradient(to left, rgba(0,0,0,1), rgba(0,0,0,0)), linear-gradient(to right, rgba(0,0,0,1), rgba(0,0,0,0));_x000D_
  -webkit-mask-size: 100% 50%;_x000D_
  -webkit-mask-repeat: no-repeat;_x000D_
  -webkit-mask-position: left top, left bottom;_x000D_
  }_x000D_
_x000D_
div {_x000D_
    background-color: lightblue;_x000D_
}

<div><p>text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text </p></div>

Now, another approach is available, that is supported by Chrome, Firefox, Safari and Opera.

The idea is to use

mix-blend-mode: hard-light;

that gives transparency if the color is gray. Then, a grey overlay on the element creates the transparency

div {_x000D_
  background-color: lightblue;_x000D_
}_x000D_
_x000D_
p {_x000D_
  color: red;_x000D_
  overflow: hidden;_x000D_
  position: relative;_x000D_
  width: 200px;_x000D_
  mix-blend-mode: hard-light;_x000D_
}_x000D_
_x000D_
p::after {_x000D_
  position: absolute;_x000D_
  content: "";_x000D_
  left: 0px;_x000D_
  top: 0px;_x000D_
  height: 100%;_x000D_
  width: 100%;_x000D_
  background: linear-gradient(transparent, gray);_x000D_
  pointer-events: none;_x000D_
}

<div><p>text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text </p></div>

If you need to remove the HTML but does not know if it actually contains any HTML tags, you can't use the jQuery method directly because it returns empty wrapper for non-HTML text.

$('<div>Hello world</div>').text(); //returns "Hello world"
$('Hello world').text(); //returns empty string ""

You must either wrap the text in valid HTML:

$('<div>' + 'Hello world' + '</div>').text();

Or use method $.parseHTML() (since jQuery 1.8) that can handle both HTML and non-HTML text:

var html = $.parseHTML('Hello world'); //parseHTML return HTMLCollection
var text = $(html).text(); //use $() to get .text() method

Plus parseHTML removes script tags completely which is useful as anti-hacking protection for user inputs.

$('<p>Hello world</p><script>console.log(document.cookie)</script>').text();
//returns "Hello worldconsole.log(document.cookie)"

$($.parseHTML('<p>Hello world</p><script>console.log(document.cookie)</script>')).text();
//returns "Hello world"

The first parameter to the iterator in forEach is the value and second is the key of the object.

angular.forEach(objectToIterate, function(value, key) {
    /* do something for all key: value pairs */
});

In your example, the outer forEach is actually:

angular.forEach($scope.filters, function(filterObj , filterKey)

Hope this will help you..

var list = [];
    $(document).ready(function () {
        $('#test').click(function () {
            var oRows = $('#MainContent_Table1 tr').length;
            $('#MainContent_Table1 tr').each(function (index) {
                list.push(this.cells[0].innerHTML);
            });
        });
    });

You can use 'th:if' together with 'th:text'

<span th:if="${someObject.someProperty != null}" th:text="${someObject.someProperty}">someValue</span>

If you are using model type List< T>/ArrayList< T> . Hope,it's help you.

Here is my code without using any other data structure like set or hashmap

for (int i = 0; i < Models.size(); i++){
for (int j = i + 1; j < Models.size(); j++) {       
 if (Models.get(i).getName().equals(Models.get(j).getName())) {    
 Models.remove(j);
   j--;
  }
 }
}

With Java 8's lambdas, a convenient way is to use

org.mockito.invocation.InvocationOnMock

when(client.deleteByQuery(anyString(), anyString())).then(invocationOnMock -> {
    assertEquals("myCollection", invocationOnMock.getArgument(0));
    assertThat(invocationOnMock.getArgument(1), Matchers.startsWith("id:"));
}

Inspired by @Addison I've rewritten the extension without the use of any third party framework, as he used SnapKit and CocoaLumberjack.

As in @Addisons approach I'm also removing previously added borders, so this implementation should play nice with reusable views as table cells and collection cells.

fileprivate class BorderView: UIView {} // dummy class to help us differentiate among border views and other views
                                        // to enabling us to remove existing borders and place new ones

extension UIView {

    func setBorders(toEdges edges: [UIRectEdge], withColor color: UIColor, inset: CGFloat = 0, thickness: CGFloat) {
        // Remove existing edges
        for view in subviews {
            if view is BorderView {
                view.removeFromSuperview()
            }
        }
        // Add new edges
        if edges.contains(.all) {
            addSidedBorder(toEdge: [.left,.right, .top, .bottom], withColor: color, inset: inset, thickness: thickness)
        }
        if edges.contains(.left) {
            addSidedBorder(toEdge: [.left], withColor: color, inset: inset, thickness: thickness)
        }
        if edges.contains(.right) {
            addSidedBorder(toEdge: [.right], withColor: color, inset: inset, thickness: thickness)
        }
        if edges.contains(.top) {
            addSidedBorder(toEdge: [.top], withColor: color, inset: inset, thickness: thickness)
        }
        if edges.contains(.bottom) {
            addSidedBorder(toEdge: [.bottom], withColor: color, inset: inset, thickness: thickness)
        }
    }

    private func addSidedBorder(toEdge edges: [RectangularEdges], withColor color: UIColor, inset: CGFloat = 0, thickness: CGFloat) {
        for edge in edges {
            let border = BorderView(frame: .zero)
            border.backgroundColor = color
            addSubview(border)
            border.translatesAutoresizingMaskIntoConstraints = false

When you are reading the file, have you considered reading it line by line? This would allow you to check if your line contains the file as your are reading, and you could then perform whatever logic you needed based on that?

Scanner scanner = new Scanner("Student.txt");
String currentLine;

while((currentLine = scanner.readLine()) != null)
{
    if(currentLine.indexOf("Your String"))
    {
         //Perform logic
    }
}

You could use a variable to hold the line number, or you could also have a boolean indicating if you have passed the line that contains your string:

Scanner scanner = new Scanner("Student.txt");
String currentLine;
int lineNumber = 0;
Boolean passedLine = false;
while((currentLine = scanner.readLine()) != null)
{
    if(currentLine.indexOf("Your String"))
    {
         //Do task
         passedLine = true;
    }
    if(passedLine)
    {
       //Do other task after passing the line.
    }
    lineNumber++;
}

I think you want something along the line of:

Parent:

<Editor name={this.state.fileData} />

Editor:

var Editor = React.createClass({
  displayName: 'Editor',
  propTypes: {
    name: React.PropTypes.string.isRequired
  },
  getInitialState: function() { 
    return {
      value: this.props.name
    };
  },
  handleChange: function(event) {
    this.setState({value: event.target.value});
  },
  render: function() {
    return (
      <form id="noter-save-form" method="POST">
        <textarea id="noter-text-area" name="textarea" value={this.state.value} onChange={this.handleChange} />
        <input type="submit" value="Save" />
      </form>
    );
  }
});

This is basically a direct copy of the example provided on https://facebook.github.io/react/docs/forms.html

Update for React 16.8:

import React, { useState } from 'react';

const Editor = (props) => {
    const [value, setValue] = useState(props.name);

    const handleChange = (event) => {
        setValue(event.target.value);
    };

    return (
        <form id="noter-save-form" method="POST">
            <textarea id="noter-text-area" name="textarea" value={value} onChange={handleChange} />
            <input type="submit" value="Save" />
        </form>
    );
}

Editor.propTypes = {
    name: PropTypes.string.isRequired
};

Here is the solution for Ubuntu users

First we have to stop postgresql

sudo /etc/init.d/postgresql stop

Create a new file called /etc/apt/sources.list.d/pgdg.list and add below line

deb http://apt.postgresql.org/pub/repos/apt/ utopic-pgdg main

Follow below commands

wget -q -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update
sudo apt-get install postgresql-9.4
sudo pg_dropcluster --stop 9.4 main 
sudo /etc/init.d/postgresql start

Now we have everything, just need to upgrade it as below

sudo pg_upgradecluster 9.3 main
sudo pg_dropcluster 9.3 main

That's it. Mostly upgraded cluster will run on port number 5433. Check it with below command

sudo pg_lsclusters

It happens mostly when JQuery is not installed in your project. Install JQuery in your project by following commands according to your package manager.

Yarn

yarn add jquery

npm

npm i jquery --save

After this just import $ in your project file. import $ from 'jquery'

overflow-x: hidden;
would hide any thing on the x-axis that goes outside of the element, so there would be no need for the horizontal scrollbar and it get removed.

overflow-y: hidden;
would hide any thing on the y-axis that goes outside of the element, so there would be no need for the vertical scrollbar and it get removed.

overflow: hidden;
would remove both scrollbars

Unfortunately, np.polynomial.polynomial.polyfit returns the coefficients in the opposite order of that for np.polyfit and np.polyval (or, as you used np.poly1d). To illustrate:

In [40]: np.polynomial.polynomial.polyfit(x, y, 4)
Out[40]: 
array([  84.29340848, -100.53595376,   44.83281408,   -8.85931101,
          0.65459882])

In [41]: np.polyfit(x, y, 4)
Out[41]: 
array([   0.65459882,   -8.859311  ,   44.83281407, -100.53595375,
         84.29340846])

In general: np.polynomial.polynomial.polyfit returns coefficients [A, B, C] to A + Bx + Cx^2 + ..., while np.polyfit returns: ... + Ax^2 + Bx + C.

So if you want to use this combination of functions, you must reverse the order of coefficients, as in:

ffit = np.polyval(coefs[::-1], x_new)

However, the documentation states clearly to avoid np.polyfit, np.polyval, and np.poly1d, and instead to use only the new(er) package.

You're safest to use only the polynomial package:

import numpy.polynomial.polynomial as poly

coefs = poly.polyfit(x, y, 4)
ffit = poly.polyval(x_new, coefs)
plt.plot(x_new, ffit)

Or, to create the polynomial function:

ffit = poly.Polynomial(coefs)    # instead of np.poly1d
plt.plot(x_new, ffit(x_new))

On linux mint 17, this is working.

             } 
             else{
                 System.out.println("The interger number you entered is not divisible by 5");
             }
        }

    }
}

As far as I know, there is no such a thing as iOS emulator on windows or linux, there are only some gameengines that enable you to compile same code for both iOS and windows or linux and there is a toolchain to compile iOS application using linux. none of them are realy emulator/simulator things. and to use that toolchain you need a jailbreaked iOS device to test binary file created using toolchain. I mean linux itself can't run the binary created itself. and by the way even in mac simulator is just an intermediate program which runs mac-compiled binary, since if you change compiling for iOS from simulator or the other way, all the files are rebuild. and also there are some real differences, like iOS is a case-sensitive operation while simulator is not.

so the best solution is to buy an iOS device yourself.

if you need to change specific option from the select menu you can do it like this

option[value="Basic"] {
  color:red;
 }

or you can change them all

select {
  color:red;
}

Usually, IllegalStateException is used to indicate that "a method has been invoked at an illegal or inappropriate time." However, this doesn't look like a particularly typical use of it.

The code you've linked to shows that it can be thrown within that code at line 259 - but only after dumping a SQLException to standard output.

We can't tell what's wrong just from that exception - and better code would have used the original SQLException as a "cause" exception (or just let the original exception propagate up the stack) - but you should be able to see more details on standard output. Look at that information, and you should be able to see what caused the exception, and fix it.

This error can also show up if there are parts in your string that json.loads() does not recognize. An in this example string, an error will be raised at character 27 (char 27).

string = """[{"Item1": "One", "Item2": False}, {"Item3": "Three"}]"""

My solution to this would be to use the string.replace() to convert these items to a string:

import json

string = """[{"Item1": "One", "Item2": False}, {"Item3": "Three"}]"""

string = string.replace("False", '"False"')

dict_list = json.loads(string)

To disable the blue glow (but you can modify the code to change color, size, etc), add this to your css:

.search-form input[type="search"] {  
    -webkit-box-shadow: none;
    outline: -webkit-focus-ring-color auto 0px;
} 

Here's a screencapture showing the effect: before and after:

I asume you have connected to your database already.

$sql = "SELECT * FROM my_table";
$result = mysql_query($sql);

$row = 1; // 1-based index
while($row_data = mysql_fetch_assoc($result)) {
    $col = 0;
    foreach($row_data as $key=>$value) {
        $objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $value);
        $col++;
    }
    $row++;
}

I was looking for a similar functionality some days back and came across a good tutorial on tutorialzine. Here is an working example. Complete tutorial can be found here.

Simple form to hold the file upload dialogue:

<form id="upload" method="post" action="upload.php" enctype="multipart/form-data">
  <input type="file" name="uploadctl" multiple />
  <ul id="fileList">
    <!-- The file list will be shown here -->
  </ul>
</form>

And here is the jQuery code to upload the files:

$('#upload').fileupload({

  // This function is called when a file is added to the queue
  add: function (e, data) {
    //This area will contain file list and progress information.
    var tpl = $('<li class="working">'+
                '<input type="text" value="0" data-width="48" data-height="48" data-fgColor="#0788a5" data-readOnly="1" data-bgColor="#3e4043" />'+
                '<p></p><span></span></li>' );

    // Append the file name and file size
    tpl.find('p').text(data.files[0].name)
                 .append('<i>' + formatFileSize(data.files[0].size) + '</i>');

    // Add the HTML to the UL element
    data.context = tpl.appendTo(ul);

    // Initialize the knob plugin. This part can be ignored, if you are showing progress in some other way.
    tpl.find('input').knob();

    // Listen for clicks on the cancel icon
    tpl.find('span').click(function(){
      if(tpl.hasClass('working')){
              jqXHR.abort();
      }
      tpl.fadeOut(function(){
              tpl.remove();
      });
    });

    // Automatically upload the file once it is added to the queue
    var jqXHR = data.submit();
  },
  progress: function(e, data){

        // Calculate the completion percentage of the upload
        var progress = parseInt(data.loaded / data.total * 100, 10);

        // Update the hidden input field and trigger a change
        // so that the jQuery knob plugin knows to update the dial
        data.context.find('input').val(progress).change();

        if(progress == 100){
            data.context.removeClass('working');
        }
    }
});
//Helper function for calculation of progress
function formatFileSize(bytes) {
    if (typeof bytes !== 'number') {
        return '';
    }

    if (bytes >= 1000000000) {
        return (bytes / 1000000000).toFixed(2) + ' GB';
    }

    if (bytes >= 1000000) {
        return (bytes / 1000000).toFixed(2) + ' MB';
    }
    return (bytes / 1000).toFixed(2) + ' KB';
}

And here is the PHP code sample to process the data:

if($_POST) {
    $allowed = array('jpg', 'jpeg');

    if(isset($_FILES['uploadctl']) && $_FILES['uploadctl']['error'] == 0){

        $extension = pathinfo($_FILES['uploadctl']['name'], PATHINFO_EXTENSION);

        if(!in_array(strtolower($extension), $allowed)){
            echo '{"status":"error"}';
            exit;
        }

        if(move_uploaded_file($_FILES['uploadctl']['tmp_name'], "/yourpath/." . $extension)){
            echo '{"status":"success"}';
            exit;
        }
        echo '{"status":"error"}';
    }
    exit();
}

The above code can be added to any existing form. This program automatically uploads images, once they are added. This functionality can be changed and you can submit the image, while you are submitting your existing form.

Try to nest two setTimeout functions within each other and they will behave multithreaded (ie; the outer timer won't wait for the inner one to complete before executing its function).

The internal representation of int and unsigned int is the same.

Therefore, when you pass the same format string to printf it will be printed as the same.

However, there are differences when you compare them. Consider:

int x = 0x7FFFFFFF;
int y = 0xFFFFFFFF;
x < y // false
x > y // true
(unsigned int) x < (unsigned int y) // true
(unsigned int) x > (unsigned int y) // false

This can be also a caveat, because when comparing signed and unsigned integer one of them will be implicitly casted to match the types.

You can also use regular expressions to include / exclude some files /dirs your search using something like this:

find . -regextype posix-egrep -regex ".*\.(js|vue|s?css|php|html|json)$" -and -not -regex ".*/(node_modules|vendor)/.*" 

This will only give you all js, vue, css, etc files but excluding all files in the node_modules and vendor folders.

You could add another empty layout below that one and set them both to have the same layout weight. They should get 50% of the space each.

Another option is to delete all the classes and rebuild. Having build file is an ideal solution to control whole process like compilation, packaging and deployment. You can also specify source/target versions

Taking a column is easy with the map function.

// a two-dimensional array
var two_d = [[1,2,3],[4,5,6],[7,8,9]];

// take the third column
var col3 = two_d.map(function(value,index) { return value[2]; });

Why bother with the slice at all? Just filter the matrix to find the rows of interest.

var interesting = two_d.filter(function(value,index) {return value[1]==5;});
// interesting is now [[4,5,6]]

Sadly, filter and map are not natively available on IE9 and lower. The MDN documentation provides implementations for browsers without native support.

I have a raspberry pi, and I am using python web server (using Flask). I have tried everything above, the only solution is to close the terminal(shell) and open it again. Or restart the raspberry pi, because nothing stops that webserver...

You can now use RPC libraries that support Python and Javascript such as zerorpc

From their front page:

Node.js Client

var zerorpc = require("zerorpc");

var client = new zerorpc.Client();
client.connect("tcp://127.0.0.1:4242");

client.invoke("hello", "RPC", function(error, res, more) {
    console.log(res);
});

Python Server

import zerorpc

class HelloRPC(object):
    def hello(self, name):
        return "Hello, %s" % name

s = zerorpc.Server(HelloRPC())
s.bind("tcp://0.0.0.0:4242")
s.run()

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

or use

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

Just to add my two cents in the debate I have made a pure angular module (no jquery), and it will also work with hash urls containing data. (i.g. #/this/is/path?this=is&some=data)

You just add the module as a dependency and auto-active to one of the ancestors of the menu. Like this:

<ul auto-active>
    <li><a href="#/">main</a></li>
    <li><a href="#/first">first</a></li>
    <li><a href="#/second">second</a></li>
    <li><a href="#/third">third</a></li>
</ul>

And the module look like this:

(function () {
    angular.module('autoActive', [])
        .directive('autoActive', ['$location', function ($location) {
        return {
            restrict: 'A',
            scope: false,
            link: function (scope, element) {
                function setActive() {
                    var path = $location.path();
                    if (path) {
                        angular.forEach(element.find('li'), function (li) {
                            var anchor = li.querySelector('a');
                            if (anchor.href.match('#' + path + '(?=\\?|$)')) {
                                angular.element(li).addClass('active');
                            } else {
                                angular.element(li).removeClass('active');
                            }
                        });
                    }
                }

                setActive();

                scope.$on('$locationChangeSuccess', setActive);
            }
        }
    }]);
}());

* (You can of course just use the directive part)

** It's also worth noticing that this doesn't work for empty hashes (i.g. example.com/# or just example.com) it needs to have at least example.com/#/ or just example.com#/. But this happens automatically with ngResource and the like.

Use

a = sorted(a, key=lambda x: x.modified, reverse=True)
#             ^^^^

On Python 2.x, the sorted function takes its arguments in this order:

sorted(iterable, cmp=None, key=None, reverse=False)

so without the key=, the function you pass in will be considered a cmp function which takes 2 arguments.

Here's a little trick I discovered using the :before and :after pseudo-elements:

.depth {
    color: black;
    position: relative;
}
.depth:before, .depth:after {
    content: attr(title);
    color: rgba(255,255,255,.1);
    position: absolute;
}
.depth:before { top: 1px; left: 1px }
.depth:after  { top: 2px; left: 2px }

The title attribute needs to be the same as the content. Demo: http://dabblet.com/gist/1609945

I have used Debian-family distros which appear to execute .profile, but not .bash_profile, whereas RHEL derivatives execute .bash_profile before .profile.

It seems to be a mess when you have to set up environment variables to work in any Linux OS.

If you are using python3 on windows then you might do this as well

pip3 install tensorflow==1.4

you may select any version from "(from versions: 1.2.0rc2, 1.2.0, 1.2.1, 1.3.0rc0, 1.3.0rc1, 1.3.0rc2, 1.3.0, 1.4.0rc0, 1.4.0rc1, 1.4.0, 1.5.0rc0, 1.5.0rc1, 1.5.0, 1.5.1, 1.6.0rc0, 1.6.0rc1, 1.6.0, 1.7.0rc0, 1.7.0rc1, 1.7.0)"

I did this when I wanted to downgrade from 1.7 to 1.4

This is the correct way:

To execute code that will only be available to the index page, we could use this syntax:

$(document).on('pageinit', "#index",  function() {
    ...
});

As the previous answers exhaustively covered the theory behind the value categories, there is just another thing I'd like to add: you can actually play with it and test it.

For some hands-on experimentation with the value categories, you can make use of the decltype specifier. Its behavior explicitly distinguishes between the three primary value categories (xvalue, lvalue, and prvalue).

Using the preprocessor saves us some typing ...

Primary categories:

#define IS_XVALUE(X) std::is_rvalue_reference<decltype((X))>::value
#define IS_LVALUE(X) std::is_lvalue_reference<decltype((X))>::value
#define IS_PRVALUE(X) !std::is_reference<decltype((X))>::value

Mixed categories:

#define IS_GLVALUE(X) (IS_LVALUE(X) || IS_XVALUE(X))
#define IS_RVALUE(X) (IS_PRVALUE(X) || IS_XVALUE(X))

Now we can reproduce (almost) all the examples from cppreference on value category.

Here are some examples with C++17 (for terse static_assert):

void doesNothing(){}
struct S
{
    int x{0};
};
int x = 1;
int y = 2;
S s;

static_assert(IS_LVALUE(x));
static_assert(IS_LVALUE(x+=y));
static_assert(IS_LVALUE("Hello world!"));
static_assert(IS_LVALUE(++x));

static_assert(IS_PRVALUE(1));
static_assert(IS_PRVALUE(x++));
static_assert(IS_PRVALUE(static_cast<double>(x)));
static_assert(IS_PRVALUE(std::string{}));
static_assert(IS_PRVALUE(throw std::exception()));
static_assert(IS_PRVALUE(doesNothing()));

static_assert(IS_XVALUE(std::move(s)));
// The next one doesn't work in gcc 8.2 but in gcc 9.1. Clang 7.0.0 and msvc 19.16 are doing fine.
static_assert(IS_XVALUE(S().x)); 

The mixed categories are kind of boring once you figured out the primary category.

For some more examples (and experimentation), check out the following link on compiler explorer. Don't bother reading the assembly, though. I added a lot of compilers just to make sure it works across all the common compilers.

A multiple select is really just a select with a multiple attribute. With that in mind, it should be as easy as...

Form::select('sports[]', $sports, null, array('multiple'))

The first parameter is just the name, but post-fixing it with the [] will return it as an array when you use Input::get('sports').

The second parameter is an array of selectable options.

The third parameter is an array of options you want pre-selected.

The fourth parameter is actually setting this up as a multiple select dropdown by adding the multiple property to the actual select element..

This solution works like a charm (updated in 2017 to honor that log_format needs to be in the http part of the nginx config):

log_format postdata $request_body;

server {
    # (...)

    location = /post.php {
       access_log  /var/log/nginx/postdata.log  postdata;
       fastcgi_pass php_cgi;
    }
}

I think the trick is making nginx believe that you will call a cgi script.

You can store the size somewhere, or you can have a struct with a special value set that you use as a sentinel, the same way that '\0' indicates the end of a string.

Try this:

for(String str: myList) {
    if(str.trim().equals("A"))
       return true;
}
return false;

You need to use str.equals or str.equalsIgnoreCase instead of contains because contains in string works not the same as contains in List

List<String> s = Arrays.asList("BAB", "SAB", "DAS");
s.contains("A"); // false
"BAB".contains("A"); // true

I believe this might Help:

    System.out.println(Integer.toBinaryString(2 << 0));
    System.out.println(Integer.toBinaryString(2 << 1));
    System.out.println(Integer.toBinaryString(2 << 2));
    System.out.println(Integer.toBinaryString(2 << 3));
    System.out.println(Integer.toBinaryString(2 << 4));
    System.out.println(Integer.toBinaryString(2 << 5));

Result

    10
    100
    1000
    10000
    100000
    1000000

Unless you have some kind of really weird problem, keep it. The number of IPv6 sites is very small, but there are some and it will let you get to them even if you're at an IPv4 only location.

If it is causing you a problem, it's best to fix it. I've seen a number of people recommending removing it to solve problems. However, they're not actually solving the root cause of the issue. In all the cases I've seen, removing Teredo just happens to cause a side-effect that fixes their problem... :)

I wasn't satisfied with these answers since I wanted to ensure the exported values had the same ordering even when using different dicts.

Here you specify the key order upfront, the returned values will always have the same order even if the dict changes, or you use a different dict.

keys = dict1.keys()
ordered_keys1 = [dict1[cur_key] for cur_key in keys]
ordered_keys2 = [dict2[cur_key] for cur_key in keys]

If you want to remove the default value constraint, you can do:

ALTER TABLE <table> ALTER COLUMN <column> DROP DEFAULT;

Won't simply concatenating the part of your path accomplish what you want?

$ base="/home/user1/MyFolder/"
$ subdir="subFold1"
$ new_path=$base$subdir
$ echo $new_path
/home/user1/MyFolder/subFold1

You can then create the folders/directories as needed.

One convention is to end directory paths with / (e.g. /home/) because paths starting with a / could be confused with the root directory. If a double slash (//) is used in a path, it is also still correct. But, if no slash is used on either variable, it would be incorrect (e.g. /home/user1/MyFoldersubFold1).

Use

&#013

There shouldn't be any ; character.

We're trying this on a short list that does not do any view recycling. So far so good.

XML:

<RitalinLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >
  <ListView
      android:id="@+id/cart_list"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:scrollbarStyle="outsideOverlay"
      />
</RitalinLayout>

Java:

/**
 * It helps you keep focused.
 *
 * For use as a parent of {@link android.widget.ListView}s that need to use EditText
 * children for inline editing.
 */
public class RitalinLayout extends FrameLayout {
  View sticky;

  public RitalinLayout(Context context, AttributeSet attrs) {
    super(context, attrs);

    ViewTreeObserver vto = getViewTreeObserver();

    vto.addOnGlobalFocusChangeListener(new ViewTreeObserver.OnGlobalFocusChangeListener() {
      @Override public void onGlobalFocusChanged(View oldFocus, View newFocus) {
        if (newFocus == null) return;

        View baby = getChildAt(0);

        if (newFocus != baby) {
          ViewParent parent = newFocus.getParent();
          while (parent != null && parent != parent.getParent()) {
            if (parent == baby) {
              sticky = newFocus;
              break;
            }
            parent = parent.getParent();
          }
        }
      }
    });

    vto.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
      @Override public void onGlobalLayout() {
        if (sticky != null) {
          sticky.requestFocus();
        }
      }
    });
  }
}

For strings or input values you could simply use this:

var a = $('#some_hidden_var').val(),
b = a.substr(0);

Here you are another general solution for any data type.

int offset = 0;
byte[] buffer = new byte[8192];

try {
    do {
        int b = inputStream.read();

        if (b == -1)
           break;

        buffer[offset++] = (byte) b;

        //check offset with buffer length and reallocate array if needed
    } while (inputStream.available() > 0);
} catch (SocketException e) {
    //connection was lost
}

//process buffer
