For CUDA 6.5 (and apparently 7.0 and 7.5), I've created a version of the gcc 4.8.5 RPM package (under Fedora Core 30) that allows that version of gcc to be install alongside your system's current GCC.

You can find all of that information here.

To add to the other answers, I think the acronyms were derived to show a scale between the two terms to distinguish how reliable transactions or requests where between RDMS versus Big Data.

From this article acid vs base

In Chemistry, pH measures the relative basicity and acidity of an aqueous (solvent in water) solution. The pH scale extends from 0 (highly acidic substances such as battery acid) to 14 (highly alkaline substances like lie); pure water at 77° F (25° C) has a pH of 7 and is neutral.

Data engineers have cleverly borrowed acid vs base from chemists and created acronyms that while not exact in their meanings, are still apt representations of what is happening within a given database system when discussing the reliability of transaction processing.

One other point, since I work with Big Data using Elasticsearch. To clarify, an instance of Elasticsearch is a node and a group of nodes form a cluster.

To me from a practical standpoint, BA (Basically Available), in this context, has the idea of multiple master nodes to handle the Elasticsearch cluster and it's operations.

If you have 3 master nodes and the currently directing master node goes down, the system stays up, albeit in a less efficient state, and another master node takes its place as the main directing master node. If two master nodes go down, the system still stays up and the last master node takes over.

You could use predefined utility type Record<Keys, Type> :

const obj: Record<string, string> = {
  property: "value",
};

It allows to specify keys for your object literal:

type Keys = "prop1" | "prop2"

const obj: Record<Keys, string> = {
  prop1: "Hello",
  prop2: "Aloha",
  something: "anything" // TS Error: Type '{ prop1: string; prop2: string; something: string; }' is not assignable to type 'Record<Keys, string>'.
                        //   Object literal may only specify known properties, and 'something' does not exist in type 'Record<Keys, string>'.
};

And a type for the property value:

type Keys = "prop1" | "prop2"
type Value = "Hello" | "Aloha"

const obj1: Record<Keys, Value> = {
  prop1: "Hello",
  prop2: "Hey", // TS Error: Type '"Hey"' is not assignable to type 'Value'.
};

# indicates that the following line is a preprocessor directive and should be processed by the preprocessor before compilation by the compiler.

So, #include is a preprocessor directive that tells the preprocessor to include header files in the program.

< > indicate the start and end of the file name to be included.

iostream is a header file that contains functions for input/output operations (cin and cout).

Now to sum it up C++ to English translation of the command, #include <iostream> is:

Dear preprocessor, please include all the contents of the header file iostream at the very beginning of this program before compiler starts the actual compilation of the code.

There is a solution even if you don't want to remove your local changes. Just fix the unmerged files (by git add or git remove). Then do git pull.

You can use pandas library and reference the rows and columns like this:

import pandas as pd

input = pd.read_csv("path_to_file");

#for accessing ith row:
input.iloc[i]

#for accessing column named X
input.X

#for accessing ith row and column named X
input.iloc[i].X

I tried a bunch of these but none of them worked for all of my tests. So I found this:

One note on the above answers: it is no longer sufficient to add just pypi.python.org to the trusted-hosts in the case where you are behind an HTTPS-intercepting proxy (we have zScaler).

I currently have the following in my pip.ini:

trusted-host = pypi.python.org pypi.org files.pythonhosted.org

Running pip -v install pkg will give you some hints as to which hosts might need to be added.

You have not joined TableD, merely selected the TableD FIELD (dID) from one of the tables.

Most answers are surprisingly complicated or erroneous. However simple and robust examples have been posted elsewhere [codereview]. Admittedly the options provided by the gnu preprocessor are a bit confusing. However, the removal of all directories from the build target with -MM is documented and not a bug [gpp]:

By default CPP takes the name of the main input file, deletes any directory components and any file suffix such as ‘.c’, and appends the platform's usual object suffix.

The (somewhat newer) -MMD option is probably what you want. For completeness an example of a makefile that supports multiple src dirs and build dirs with some comments. For a simple version without build dirs see [codereview].

CXX = clang++
CXX_FLAGS = -Wfatal-errors -Wall -Wextra -Wpedantic -Wconversion -Wshadow

# Final binary
BIN = mybin
# Put all auto generated stuff to this build dir.
BUILD_DIR = ./build

# List of all .cpp source files.
CPP = main.cpp $(wildcard dir1/*.cpp) $(wildcard dir2/*.cpp)

# All .o files go to build dir.
OBJ = $(CPP:%.cpp=$(BUILD_DIR)/%.o)
# Gcc/Clang will create these .d files containing dependencies.
DEP = $(OBJ:%.o=%.d)

# Default target named after the binary.
$(BIN) : $(BUILD_DIR)/$(BIN)

# Actual target of the binary - depends on all .o files.
$(BUILD_DIR)/$(BIN) : $(OBJ)
    # Create build directories - same structure as sources.
    mkdir -p $(@D)
    # Just link all the object files.
    $(CXX) $(CXX_FLAGS) $^ -o $@

# Include all .d files
-include $(DEP)

# Build target for every single object file.
# The potential dependency on header files is covered
# by calling `-include $(DEP)`.
$(BUILD_DIR)/%.o : %.cpp
    mkdir -p $(@D)
    # The -MMD flags additionaly creates a .d file with
    # the same name as the .o file.
    $(CXX) $(CXX_FLAGS) -MMD -c $< -o $@

.PHONY : clean
clean :
    # This should remove all generated files.
    -rm $(BUILD_DIR)/$(BIN) $(OBJ) $(DEP)

This method works because if there are multiple dependency lines for a single target, the dependencies are simply joined, e.g.:

a.o: a.h
a.o: a.c
    ./cmd

is equivalent to:

a.o: a.c a.h
    ./cmd

as mentioned at: Makefile multiple dependency lines for a single target?

You shouldn't be calling .ToString().

As the error message clearly states, you're writing a conditional in which one half is an IHtmlString and the other half is a string.
That doesn't make sense, since the compiler doesn't know what type the entire expression should be.

There is never a reason to call Html.Raw(...).ToString().
Html.Raw returns an HtmlString instance that wraps the original string.
The Razor page output knows not to escape HtmlString instances.

However, calling HtmlString.ToString() just returns the original string value again; it doesn't accomplish anything.

In my case, I upgraded node.js version to latest (version 12.8.0) and it worked like a charm.

As simple as:

your_map.begin()->first // key
your_map.begin()->second // value

A trick I haven't seen on here yet that doesn't use extglob, find, or grep is to treat two file lists as sets and "diff" them using comm:

comm -23 <(ls) <(ls *Music*)

comm is preferable over diff because it doesn't have extra cruft.

This returns all elements of set 1, ls, that are not also in set 2, ls *Music*. This requires both sets to be in sorted order to work properly. No problem for ls and glob expansion, but if you're using something like find, be sure to invoke sort.

comm -23 <(find . | sort) <(find . | grep -i '.jpg' | sort)

Potentially useful.

The JavaScript function:

String.prototype.capitalize = function(){
       return this.replace( /(^|\s)([a-z])/g , function(m,p1,p2){ return p1+p2.toUpperCase(); } );
      };

To use this function:

capitalizedString = someString.toLowerCase().capitalize();

Also, this would work on multiple words string.

To make sure the converted City name is injected into the database, lowercased and first letter capitalized, then you would need to use JavaScript before you send it over to server side. CSS simply styles, but the actual data would remain pre-styled. Take a look at this jsfiddle example and compare the alert message vs the styled output.

Follow all the steps.

Step 1: initialize git

$ git init

Step 2: Check files are exist or not.

$git ls

Step 3 : Add the file

$git add filename

Step 4: Add comment to show

$git commit -m "your comment"

Step 5: Link to your repository

$git remote add origin  "copy repository link  and paste here"

Step 6: Push on Git

$ git push -u origin master

I had the same problem. I'm using DB2. What I have done is a bit not too professional solution, but it works in every DBMS:

1. Add a column with the same definition without the unique contraint.
2. Copy the values from the original column to the new
3. Drop the original column (so DBMS will remove the constraint as well no matter what its name was)
4. And finally rename the new one to the original
5. And a reorg at the end (only in DB2)

ALTER TABLE USERS ADD COLUMN LOGIN_OLD VARCHAR(50) NOT NULL DEFAULT '';
UPDATE USERS SET LOGIN_OLD=LOGIN;
ALTER TABLE USERS DROP COLUMN LOGIN;
ALTER TABLE USERS RENAME COLUMN LOGIN_OLD TO LOGIN;

CALL SYSPROC.ADMIN_CMD('REORG TABLE USERS');

The syntax of the ALTER commands may be different in other DBMS

You can use the key argument in sorted() method unless you have two same values in list2.

The code is given below:

sorted(list2, key = lambda x: list1[list2.index(x)]) 

It sorts list2 according to corresponding values in list1, but make sure that while using this, no two values in list2 evaluate to be equal because list.index() function give the first value

My objective is to check if the 'onEditButtonClick' is getting invoked when the user clicks the edit button and not checking just the console.log being printed.

You will need to first set up the test using the Angular TestBed. This way you can actually grab the button and click it. What you will do is configure a module, just like you would an @NgModule, just for the testing environment

import { TestBed, async, ComponentFixture } from '@angular/core/testing';

describe('', () => {
  let fixture: ComponentFixture<TestComponent>;
  let component: TestComponent;

  beforeEach(async(() => {
    TestBed.configureTestingModule({
      imports: [ ],
      declarations: [ TestComponent ],
      providers: [  ]
    }).compileComponents().then(() => {
      fixture = TestBed.createComponent(TestComponent);
      component = fixture.componentInstance;
    });
  }));
});

Then you need to spy on the onEditButtonClick method, click the button, and check that the method was called

it('should', async(() => {
  spyOn(component, 'onEditButtonClick');

  let button = fixture.debugElement.nativeElement.querySelector('button');
  button.click();

  fixture.whenStable().then(() => {
    expect(component.onEditButtonClick).toHaveBeenCalled();
  });
}));

Here we need to run an async test as the button click contains asynchronous event handling, and need to wait for the event to process by calling fixture.whenStable()

Update

It is now preferred to use fakeAsync/tick combo as opposed to the async/whenStable combo. The latter should be used if there is an XHR call made, as fakeAsync does not support it. So instead of the above code, refactored, it would look like

it('should', fakeAsync(() => {
  spyOn(component, 'onEditButtonClick');

  let button = fixture.debugElement.nativeElement.querySelector('button');
  button.click();
  tick();
  expect(component.onEditButtonClick).toHaveBeenCalled();

}));

Don't forget to import fakeAsync and tick.

The MyKey class (@Embeddable) should not have any relationships like @ManyToOne

I had the same problem with opencv-python and I used a virtual environment. If it's your case, you should find the xml files at:

/home/username/virtual_environment/lib/python3.5/site-packages/cv2/data/haarcascade_frontalface_default.xml

/home/username/virtual_environment/lib/python3.5/site-packages/cv2/data/haarcascade_eye.xml

Please be sure that you're using the absolute path. Otherwise, it won't work.

I ended up using the following:

^\d*\.?\d+$

This makes the following invalid:

.
3.

To resolve external dependencies within project. below things are important..
1. The compiler should know that where are header '.h' files located in workspace.
2. The linker able to find all specified  all '.lib' files & there names for current project.

So, Developer has to specify external dependencies for Project as below..

1. Select Project in Solution explorer.

2 . Project Properties -> Configuration Properties -> C/C++ -> General
specify all header files in "Additional Include Directories".

3.  Project Properties -> Configuration Properties -> Linker -> General
specify relative path for all lib files in "Additional Library Directories".

Try echo $'a\nb'.

If you want to store it in a variable and then use it with the newlines intact, you will have to quote your usage correctly:

var=$'a\nb\nc'
echo "$var"

Or, to fix your example program literally:

var="a b c"
for i in $var; do
    p="`echo -e "$p\\n$i"`"
done
echo "$p"

I used this for a comment section:

.parent {_x000D_
    display: flex;_x000D_
    float: left;_x000D_
    border-top:2px solid black;_x000D_
    width:635px;_x000D_
    margin:10px 0px 0px 0px;_x000D_
    padding:0px 20px 0px 20px;_x000D_
    background-color: rgba(255,255,255,0.5);_x000D_
}_x000D_
    _x000D_
.child-left {_x000D_
 align-items: stretch;_x000D_

 border-right:2px solid black;_x000D_
}_x000D_
_x000D_
.child-right {_x000D_
 align-items: stretch;_x000D_

 width:468px;_x000D_
 padding:10px;_x000D_
}

<div class="parent">_x000D_
  <div class="child-left">Short</div>_x000D_
  <div class="child-right">Tall<br>Tall</div>_x000D_
</div>

You could float the child-right to the right, but in this case I've calculated the widths of each div precisely.

I tried the above solutions. None worked.

In the end I opened Makefile file and manually changed prefix path to desired installation path like below.

PREFIX ?= "installation path"

When I tried --prefix, "make" complained that there is not such command input. However, perhaps some packages accepts --prefix which is of course a cleaner solution.

If you're open to out-of-the-DB solution: You could set up a cron job that runs a script that will itself call the procedure.

Change the file phpmyadmin.conf on c:/wamp64/alias/phpmyadmin.conf

php_admin_value upload_max_filesize 512M
php_admin_value post_max_size 512M
php_admin_value max_execution_time 360
php_admin_value max_input_time 360

It's very important you increase the time to 5000 or higher, Thus, the process will not stop when you are uploading a large file.

That works for me.

Complete copy-paste working image picker for swift 4 based on @user3182143 answer:

import Foundation
import UIKit


class ImagePickerManager: NSObject, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    var picker = UIImagePickerController();
    var alert = UIAlertController(title: "Choose Image", message: nil, preferredStyle: .actionSheet)
    var viewController: UIViewController?
    var pickImageCallback : ((UIImage) -> ())?;
    
    override init(){
        super.init()
        let cameraAction = UIAlertAction(title: "Camera", style: .default){
            UIAlertAction in
            self.openCamera()
        }
        let galleryAction = UIAlertAction(title: "Gallery", style: .default){
            UIAlertAction in
            self.openGallery()
        }
        let cancelAction = UIAlertAction(title: "Cancel", style: .cancel){
            UIAlertAction in
        }

        // Add the actions
        picker.delegate = self
        alert.addAction(cameraAction)
        alert.addAction(galleryAction)
        alert.addAction(cancelAction)
    }

    func pickImage(_ viewController: UIViewController, _ callback: @escaping ((UIImage) -> ())) {
        pickImageCallback = callback;
        self.viewController = viewController;

        alert.popoverPresentationController?.sourceView = self.viewController!.view

        viewController.present(alert, animated: true, completion: nil)
    }
    func openCamera(){
        alert.dismiss(animated: true, completion: nil)
        if(UIImagePickerController .isSourceTypeAvailable(.camera)){
            picker.sourceType = .camera
            self.viewController!.present(picker, animated: true, completion: nil)
        } else {
            let alertWarning = UIAlertView(title:"Warning", message: "You don't have camera", delegate:nil, cancelButtonTitle:"OK", otherButtonTitles:"")
            alertWarning.show()
        }
    }
    func openGallery(){
        alert.dismiss(animated: true, completion: nil)
        picker.sourceType = .photoLibrary
        self.viewController!.present(picker, animated: true, completion: nil)
    }

    
    func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
        picker.dismiss(animated: true, completion: nil)
    }
    //for swift below 4.2
    //func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    //    picker.dismiss(animated: true, completion: nil)
    //    let image = info[UIImagePickerControllerOriginalImage] as! UIImage
    //    pickImageCallback?(image)
    //}
    
    // For Swift 4.2+
    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        picker.dismiss(animated: true, completion: nil)
        guard let image = info[.originalImage] as? UIImage else {
            fatalError("Expected a dictionary containing an image, but was provided the following: \(info)")
        }
        pickImageCallback?(image)
    }



    @objc func imagePickerController(_ picker: UIImagePickerController, pickedImage: UIImage?) {
    }

}

Call it from your viewcontroller like this:

    ImagePickerManager().pickImage(self){ image in
        //here is the image
    }

Also don't forget to include the following keys in your info.plist:

<key>NSCameraUsageDescription</key>
<string>This app requires access to the camera.</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>This app requires access to the photo library.</string>

You can't set colour of the padding.

You will have to create a wrapper element with the desired background colour. Add border to this element and set it's padding.

Look here for an example: http://jsbin.com/abanek/1/edit

You can wrap all tasks which can fail in block, and use ignore_errors: yes with that block.

tasks:
  - name: ls
    command: ls -la
  - name: pwd
    command: pwd

  - block:
    - name: ls non-existing txt file
      command: ls -la no_file.txt
    - name: ls non-existing pic
      command: ls -la no_pic.jpg
    ignore_errors: yes 

Read more about error handling in blocks here.

It's very simple to implement - you should use TestContext property and TestPropertyAttribute.

Example

public TestContext TestContext { get; set; }
private List<string> GetProperties()
{
    return TestContext.Properties
        .Cast<KeyValuePair<string, object>>()
        .Where(_ => _.Key.StartsWith("par"))
        .Select(_ => _.Value as string)
        .ToList();
}

//usage
[TestMethod]
[TestProperty("par1", "http://getbootstrap.com/components/")]
[TestProperty("par2", "http://www.wsj.com/europe")]
public void SomeTest()
{
    var pars = GetProperties();
    //...
}

EDIT:

I prepared few extension methods to simplify access to the TestContext property and act like we have several test cases. See example with processing simple test properties here:

[TestMethod]
[TestProperty("fileName1", @".\test_file1")]
[TestProperty("fileName2", @".\test_file2")]
[TestProperty("fileName3", @".\test_file3")]
public void TestMethod3()
{
    TestContext.GetMany<string>("fileName").ForEach(fileName =>
    {
        //Arrange
        var f = new FileInfo(fileName);

        //Act
        var isExists = f.Exists;

        //Asssert
        Assert.IsFalse(isExists);
    });
}

and example with creating complex test objects:

[TestMethod]
//Case 1
[TestProperty(nameof(FileDescriptor.FileVersionId), "673C9C2D-A29E-4ACC-90D4-67C52FBA84E4")]
//...
public void TestMethod2()
{
    //Arrange
    TestContext.For<FileDescriptor>().Fill(fi => fi.FileVersionId).Fill(fi => fi.Extension).Fill(fi => fi.Name).Fill(fi => fi.CreatedOn, new CultureInfo("en-US", false)).Fill(fi => fi.AccessPolicy)
        .ForEach(fileInfo =>
        {
            //Act
            var fileInfoString = fileInfo.ToString();

            //Assert
            Assert.AreEqual($"Id: {fileInfo.FileVersionId}; Ext: {fileInfo.Extension}; Name: {fileInfo.Name}; Created: {fileInfo.CreatedOn}; AccessPolicy: {fileInfo.AccessPolicy};", fileInfoString);
        });
}

Take a look to the extension methods and set of samples for more details.

>>> "{:.1f}".format(45.34531)
'45.3'

Or use the builtin round:

>>> round(45.34531, 1)
45.299999999999997

Type IF /? to get help about if, it clearly explains how to use IF EXIST.

To delete a complete tree except some folders, see the answer of this question: Windows batch script to delete everything in a folder except one

Finally copying just means calling COPY and calling another bat file can be done like this:

MYOTHERBATFILE.BAT sync.bat myprogram.ini

I used something that resembles singleton pattern:

function myclass() = {
    var instance = this;

    this.Days = function() {
        var days = ["Piatek", "Sobota", "Niedziela"];
        return days;
    }

    this.EventTime = function(day, hours, minutes) {
        this.Day = instance.Days()[day];
        this.Hours = hours;
        this.minutes = minutes;
        this.TotalMinutes = day*24*60 + 60*hours + minutes;
    }
}

I don't know why I had to wast so much time, but this works for me on win 10, 64 bit:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Directory\Background\shell\cygwin_bash]
@="Open Cygwin Here"

[HKEY_CLASSES_ROOT\Directory\Background\shell\cygwin_bash\command]

& and | are bitwise operators on integral types (e.g. int): http://download.oracle.com/javase/tutorial/java/nutsandbolts/op3.html

&& and || operate on booleans only (and short-circuit, as other answers have already said).

Since you mention synaptic I think you're on Ubuntu. You probably need to run update-python-modules to update your Tkinter module for Python 3.

EDIT: Running update-python-modules

First, make sure you have python-support installed:

sudo apt-get install python-support

Then, run update-python-modules with the -a option to rebuild all the modules:

sudo update-python-modules -a

I cannot guarantee all your modules will build though, since there are some API changes between Python 2 and Python 3.

An explicit cursor is one you declare, like:

CURSOR my_cursor IS
  SELECT table_name FROM USER_TABLES

An implicit cursor is one created to support any in-line SQL you write (either static or dynamic).

• clone the element you want to blur
• append it to the element you want to be on top (the frosted window)
• blur cloned element with webkit-filter
• make sure cloned element is positioned absolute
• when scrolling the original element's parent, catch scrollTop and scrollLeft
• using requestAnimationFrame, now set the webkit-transform dynamically to translate3d with x and y values to scrollTop and scrollLeft

Example is here:

• make sure to open in webkit-browser
• scroll inside phone view (best with apple mouse...)
• see blurring footer in action

You don't need that sort of solution for string literals, since they are concatenated at the language level, and it wouldn't work anyway because "s""1" isn't a valid preprocessor token.

[Edit: In response to the incorrect "Just for the record" comment below that unfortunately received several upvotes, I will reiterate the statement above and observe that the program fragment

#define PPCAT_NX(A, B) A ## B
PPCAT_NX("s", "1")

produces this error message from the preprocessing phase of gcc: error: pasting ""s"" and ""1"" does not give a valid preprocessing token

]

However, for general token pasting, try this:

/*
 * Concatenate preprocessor tokens A and B without expanding macro definitions
 * (however, if invoked from a macro, macro arguments are expanded).
 */
#define PPCAT_NX(A, B) A ## B

/*
 * Concatenate preprocessor tokens A and B after macro-expanding them.
 */
#define PPCAT(A, B) PPCAT_NX(A, B)

Then, e.g., both PPCAT_NX(s, 1) and PPCAT(s, 1) produce the identifier s1, unless s is defined as a macro, in which case PPCAT(s, 1) produces <macro value of s>1.

Continuing on the theme are these macros:

/*
 * Turn A into a string literal without expanding macro definitions
 * (however, if invoked from a macro, macro arguments are expanded).
 */
#define STRINGIZE_NX(A) #A

/*
 * Turn A into a string literal after macro-expanding it.
 */
#define STRINGIZE(A) STRINGIZE_NX(A)

Then,

#define T1 s
#define T2 1
STRINGIZE(PPCAT(T1, T2)) // produces "s1"

By contrast,

STRINGIZE(PPCAT_NX(T1, T2)) // produces "T1T2"
STRINGIZE_NX(PPCAT_NX(T1, T2)) // produces "PPCAT_NX(T1, T2)"

#define T1T2 visit the zoo
STRINGIZE(PPCAT_NX(T1, T2)) // produces "visit the zoo"
STRINGIZE_NX(PPCAT(T1, T2)) // produces "PPCAT(T1, T2)"

Also, could be simple as:

if( typeof foo == "function" )
    foo();

You are probably missing the viewport meta tag in the html head:

 <meta name="viewport" content="width=device-width, initial-scale=1">

Without it the device assumes and sets the viewport to full size.

I would recommend %20.

Are you hard-coding them?

This is not very consistent across languages, though. If I'm not mistaken, in PHP urlencode() treats spaces as + whereas Python's urlencode() treats them as %20.

EDIT:

It seems I'm mistaken. Python's urlencode() (at least in 2.7.2) uses quote_plus() instead of quote() and thus encodes spaces as "+". It seems also that the W3C recommendation is the "+" as per here: http://www.w3.org/TR/html4/interact/forms.html#h-17.13.4.1

And in fact, you can follow this interesting debate on Python's own issue tracker about what to use to encode spaces: http://bugs.python.org/issue13866.

EDIT #2:

I understand that the most common way of encoding " " is as "+", but just a note, it may be just me, but I find this a bit confusing:

import urllib
print(urllib.urlencode({' ' : '+ '})

>>> '+=%2B+'

Recently, I've started to get an error:

npm ERR! install Couldn't read dependencies
npm ERR! Error: Invalid version: "1.0"

So, you may need to specify version of your package with 3 numbers, e.g. 1.0.0 instead of 1.0 if you get similar error.

I had the same problem and it took me around one hour to figure out where i went wrong only to note that i had used a wrong app id....just go to your code and used a correct id here

window.fbAsyncInit = function() {
    FB.init({
        appId      : '1740077446229063',//your app id
        cookie     : true,  // enable cookies to allow the server to access
        // the session
        xfbml      : true,  // parse social plugins on this page
        version    : 'v2.5' // use graph api version 2.5
    });

First, modify your search filter to only look for users and not contacts:

(&(objectCategory=person)(objectClass=user)(sAMAccountName=BTYNDALL))

You can enumerate all of the domains of a forest by connecting to the configuration partition and enumerating all the entries in the partitions container. Sorry I don't have any C# code right now but here is some vbscript code I've used in the past:

Set objRootDSE = GetObject("LDAP://RootDSE")
AdComm.Properties("Sort on") = "name"
AdComm.CommandText = "<LDAP://cn=Partitions," & _
    objRootDSE.Get("ConfigurationNamingContext") & ">;" & _
        "(&(objectcategory=crossRef)(systemFlags=3));" & _
            "name,nCName,dnsRoot;onelevel"
set AdRs = AdComm.Execute

From that you can retrieve the name and dnsRoot of each partition:

AdRs.MoveFirst
With AdRs
  While Not .EOF
    dnsRoot = .Fields("dnsRoot")

    Set objOption = Document.createElement("OPTION")
    objOption.Text = dnsRoot(0)
    objOption.Value = "LDAP://" & dnsRoot(0) & "/" & .Fields("nCName").Value
    Domain.Add(objOption)
    .MoveNext 
  Wend 
End With

Or use awk instead:

awk '/null/ { counter++; printf("%s%s%i\n",$0, " - Line number: ", NR)} END {print "Total null count: " counter}' file

You can use Objective C inside the Windows environment. If you follow these steps, it should be working just fine:

1. Visit the GNUstep website and download GNUstep MSYS Subsystem (MSYS for GNUstep), GNUstep Core (Libraries for GNUstep), and GNUstep Devel
2. After downloading these files, install in that order, or you will have problems with configuration
3. Navigate to C:\GNUstep\GNUstep\System\Library\Headers\Foundation¹ and ensure that Foundation.h exists
4. Open up a command prompt and run gcc -v to check that GNUstep MSYS is correctly installed (if you get a file not found error, ensure that the bin folder of GNUstep MSYS is in your PATH)

5. Use this simple "Hello World" program to test GNUstep's functionality:

   #include <Foundation/Foundation.h>
   
   int main(void)
   {
       NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
       NSLog(@"Hello World!.");
       [pool drain];
    return;
   }
   

6. Go back to the command prompt and cd to where you saved the "Hello World" program and then compile it:²

   gcc -o helloworld.exe <HELLOWORLD>.m -I /GNUstep/GNUstep/System/Library/Headers -L /GNUstep/GNUstep/System/Library/Libraries -std=c99 -lobjc -lgnustep-base -fconstant-string-class=NSConstantString
   

7. Finally, from the command prompt, type helloworld to run it

All the best, and have fun with Objective-C!

NOTES:

1. I used the default install path - adjust your command line accordingly
2. Ensure the folder path of yours is similar to mine, otherwise you will get an error

It's because you have turned on USB debugging in Developer Options. You can create a bug report by holding the power + both volume up and down.

Edit: This is what the forums say:

By pressing Volume up + Volume down + power button, you will feel a vibration after a second or so, that's when the bug reporting initiated.

To disable:

/system/bin/bugmailer.sh must be deleted/renamed.

There should be a folder on your SD card called "bug reports".

Pure regex answer

n.replace(/(\.[0-9]*[1-9])0+$|\.0*$/,'$1');

I wonder why no one gave one!

Untested and unsure if this will work, but why not do a few if statements before, to set variables for the switch statement.

var small, big;

if(scrollLeft < 1000){
    //add some token to the page
    //call it small
}


switch (//reference token/) {
  case (small):
   //do stuff
   break;
  case (big):
   //do stuff;
   break;
}

I came across this old question in my search for an answer, and I thought I would just post the solution I found in case someone else passes by here looking for the same.

For swapping 2 elements, Collections.swap is fine. But if we want to move more elements, there is a better solution that involves a creative use of Collections.sublist and Collections.rotate that I hadn't thought of until I saw it described here:

http://docs.oracle.com/javase/6/docs/api/java/util/Collections.html#rotate%28java.util.List,%20int%29

Here's a quote, but go there and read the whole thing for yourself too:

Note that this method can usefully be applied to sublists to move one or more elements within a list while preserving the order of the remaining elements. For example, the following idiom moves the element at index j forward to position k (which must be greater than or equal to j):

Collections.rotate(list.subList(j, k+1), -1);

You could open the file up and use StreamReader.ReadLine to read the file in line-by-line. Then you can use String.Split to break each line into pieces (use a \t delimiter) to extract the second number.

As the number of items is different you would need to search the string for the pattern 'item\*.ddj'.

To delete an item you could (for example) keep all of the file's contents in memory and write out a new file when the user clicks 'Save'.

Because I kept finding this page when looking for a way to remove a field using MongoEngine, I guess it might be helpful to post the MongoEngine way here too:

Example.objects.all().update(unset__tags__words=1)

I think you mean SqlServer but on Oracle you have a hard limit how many IN elements you can specify: 1000.

Another aspect is security (obfuscation). Once a piece of code is extracted from the main application and put in a "separated" Dynamic-Link Library, it is easier to attack, analyse (reverse-engineer) the code, since it has been isolated. When the same piece of code is kept in a LIB Library, it is part of the compiled (linked) target application, and this thus harder to isolate (differentiate) that piece of code from the rest of the target binaries.

from itertools import repeat, starmap

results = list(starmap(do, repeat((), 3)))

See the repeatfunc recipe from the itertools module that is actually much more powerful. If you need to just call the method but don't care about the return values you can use it in a for loop:

for _ in starmap(do, repeat((), 3)): pass

but that's getting ugly.

Use String.valueOf(integer).

It returns a string representation of integer.

$.each(data,function(index,itemData){
    $('#dropListBuilding').append($("<option></option>")
        .attr("value",key)
        .text(value)); 
});

If you already have mysqlclient installed (i.e. you see Requirement already satisfied) and are getting Error loading MySQLdb Module, the following worked for me:

1. pip uninstall mysqlclient
2. export LDFLAGS="-L/usr/local/opt/openssl/lib" and export CPPFLAGS="-I/usr/local/opt/openssl/include" as explained here
3. pip install mysqlclient

That reinstalls mysqlclient and for whatever reason solved my problem.

In Python, you can use urllib2 (http://docs.python.org/2/library/urllib2.html) to do all of that work for you.

Simply enough:

import urllib2
f =  urllib2.urlopen(url)
print f.read() 

Will print the received HTTP response.

To pass GET/POST parameters the urllib.urlencode() function can be used. For more information, you can refer to the Official Urllib2 Tutorial

Though the question is for button, but if anyone wants to refresh the page using <a>, you can simply do

Liviu's answer was extremely helpful for me. Hope this is not bad form but i made a fiddle that may help someone else out in the future.

Two important pieces that are needed are:

    $scope.entities = [{
    "title": "foo",
    "id": 1
}, {
    "title": "bar",
    "id": 2
}, {
    "title": "baz",
    "id": 3
}];
$scope.selected = [];

You can check for IsNull condition.

If IsNull({TABLE.FIELD}) or {TABLE.FIELD} = "" then
  // do something

It seems that there is no official solution for this problem, but there is a workaround posted here https://github.com/savoirfairelinux/python-docx/commit/afd9fef6b2636c196761e5ed34eb05908e582649

This is the source code to the Guava library's Files.createTempDir(). It's nowhere as complex as you might think:

public static File createTempDir() {
  File baseDir = new File(System.getProperty("java.io.tmpdir"));
  String baseName = System.currentTimeMillis() + "-";

  for (int counter = 0; counter < TEMP_DIR_ATTEMPTS; counter++) {
    File tempDir = new File(baseDir, baseName + counter);
    if (tempDir.mkdir()) {
      return tempDir;
    }
  }
  throw new IllegalStateException("Failed to create directory within "
      + TEMP_DIR_ATTEMPTS + " attempts (tried "
      + baseName + "0 to " + baseName + (TEMP_DIR_ATTEMPTS - 1) + ')');
}

By default:

private static final int TEMP_DIR_ATTEMPTS = 10000;

From Oracle 18c you could use DBMS_SESSION.SLEEP procedure:

This procedure suspends the session for a specified period of time.

DBMS_SESSION.SLEEP (seconds  IN NUMBER)

DBMS_SESSION.sleep is available to all sessions with no additional grants needed. Please note that DBMS_LOCK.sleep is deprecated.

If you need simple query sleep you could use WITH FUNCTION:

WITH FUNCTION my_sleep(i NUMBER)
RETURN NUMBER
BEGIN
    DBMS_SESSION.sleep(i);
    RETURN i;
END;
SELECT my_sleep(3) FROM dual;

I think System.Math.Truncate is what you're looking for.

If you're downloading text then I'd recommend using the WebClient and get a streamreader to the text:

        WebClient web = new WebClient();
        System.IO.Stream stream = web.OpenRead("http://www.yoursite.com/resource.txt");
        using (System.IO.StreamReader reader = new System.IO.StreamReader(stream))
        {
            String text = reader.ReadToEnd();
        }

If this is taking a long time then it is probably a network issue or a problem on the web server. Try opening the resource in a browser and see how long that takes. If the webpage is very large, you may want to look at streaming it in chunks rather than reading all the way to the end as in that example. Look at http://msdn.microsoft.com/en-us/library/system.io.stream.read.aspx to see how to read from a stream.

            String type = o.getClass().getSimpleName();
            switch (type) {
                case "String":
                    // treat as a String
                    break;
                case "Integer":
                    // treat as an int
                    break;
                case "Double":
                    // treat as a double
                    break;
                ...
                default:

            }
        });

I like the extension method approach so you don't have to pass through all possible parameters.
However using Regular expressions can be quite tricky (and somewhat slower) so I used XDocument instead:

public static MvcHtmlString SetDisabled(this MvcHtmlString html, bool isDisabled)
{
    var xDocument = XDocument.Parse(html.ToHtmlString());
    if (!(xDocument.FirstNode is XElement element))
    {
        return html;
    }

    element.SetAttributeValue("disabled", isDisabled ? "disabled" : null);
    return MvcHtmlString.Create(element.ToString());
}

Use the extension method like this:
@Html.EditorFor(m => m.MyProperty).SetDisabled(Model.ExpireDate == null)

CookieManager.getInstance().setAcceptCookie(true); Normally it should work if your webview is already initialized

I had the same problem;

textStatus = 'error'
errorThrown = (empty)
xhr.status = 0

That fits my problem exactly. It turns out that when I was loading the HTML-page from my own computer this problem existed, but when I loaded the HTML-page from my webserver it went alright. Then I tried to upload it to another domain, and again the same error occoured. Seems to be a cross-domain problem. (in my case at least)

I have tried calling it this way also:

var request = $.ajax({
url: "http://crossdomain.url.net/somefile.php", dataType: "text",
crossDomain: true,
xhrFields: {
withCredentials: true
}
});

but without success.

This post solved it for me: jQuery AJAX cross domain

If you are sure you haven't messed the jar, then please clean the project and perform mvn clean install. This should solve the problem.

If you have sed:

sed -e '/REFERENCE/d' -e '/ERROR/d' [FILENAME]

Where FILENAME is the name of the text file with the good & bad lines

Replace GetMonthName with GetAbbreviatedMonthName so that it reads:

string strMonthName = mfi.GetAbbreviatedMonthName(8);

Pass the sheet name with the Range parameter of the DoCmd.TransferSpreadsheet Method. See the box titled "Worksheets in the Range Parameter" near the bottom of that page.

Dim strXls As String
strXls = CurrentProject.Path & Chr(92) & "temp.xls"
DoCmd.TransferSpreadsheet acImport, , "tblFromExcel", _
    strXls, True, "temp!"

About gnibbler's answer.

Zip -function, full explanation, returns a list of tuples, where the i-th tuple contains the i-th element from each of the argument sequences or iterables. [...] construct is called list comprehension, very cool feature!

In an array you have the privilege of accessing any element in O(1) time. So its suitable for operations like Binary search Quick sort, etc. Linked list on the other hand is suitable for insertion deletion as its in O(1) time. Both has advantages as well as disadvantages and to prefer one over the other boils down to what you want to implement.

-- Bigger question is can we have a hybrid of both. Something like what python and perl implement as lists.

def determine_period(universe_array):
    period=0
    tmp=universe_array
    while period<12:
        tmp=apply_rules(tmp)#aplly_rules is a another function
        if numpy.array_equal(tmp,universe_array) is True:
            break 
        period+=1

    return period

Checkbox only offer you 2 values (true, false). Nullable boolean has 3 values (true, false, null) so it's impossible to do it with a checkbox.

A good option is to use a drop down instead.

Model

public bool? myValue;
public List<SelectListItem> valueList;

Controller

model.valueList = new List<SelectListItem>();
model.valueList.Add(new SelectListItem() { Text = "", Value = "" });
model.valueList.Add(new SelectListItem() { Text = "Yes", Value = "true" });
model.valueList.Add(new SelectListItem() { Text = "No", Value = "false" });

View

@Html.DropDownListFor(m => m.myValue, valueList)

This's Because!

1. The timeout function callbacks are all running well after the completion of the loop. In fact, as timers go, even if it was setTimeout(.., 0) on each iteration, all those function callbacks would still run strictly after the completion of the loop, that's why 3 was reflected!
2. all two of those functions, though they are defined separately in each loop iteration, are closed over the same shared global scope, which has, in fact, only one i in it.

the Solution's declaring a single scope for each iteration by using a self-function executed(anonymous one or better IIFE) and having a copy of i in it, like this:

for (var i = 1; i <= 2; i++) {

     (function(){

         var j = i;
         setTimeout(function() { console.log(j) }, 100);

     })();

}

the cleaner one would be

for (var i = 1; i <= 2; i++) {

     (function(i){ 

         setTimeout(function() { console.log(i) }, 100);

     })(i);

}

The use of an IIFE(self-executed function) inside each iteration created a new scope for each iteration, which gave our timeout function callbacks the opportunity to close over a new scope for each iteration, one which had a variable with the right per-iteration value in it for us to access.

Now you need 1 adapter for all RecyclerView

• One adapter can be used in for all RecyclerView. So NO onBindViewHolder, No onCreateViewHolder handling.
• No code for setting adapter from Java/Kotlin class. Check sample class.
• You can set events and custom data for every list by using Binding Adapters.

I show here setting two different RecyclerView by 1 adapter -

        <android.support.v7.widget.RecyclerView
            rvItemLayout="@{@layout/row_one}"
            rvList="@{listOne}"
            rvOnItemClick="@{onItemClickListenerOne}"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:layoutManager="android.support.v7.widget.LinearLayoutManager"
            />

        <android.support.v7.widget.RecyclerView
            rvItemLayout="@{@layout/row_two}"
            rvList="@{listTwo}"
            rvOnItemClick="@{onItemClickListenerTwo}"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:layoutManager="android.support.v7.widget.LinearLayoutManager"
            />

    </LinearLayout>

</layout>

You can see I pass list, item layout id and click listener from layout.

rvItemLayout="@{@layout/row_one}"
rvList="@{listOne}"
rvOnItemClick="@{onItemClickListenerOne}"

This custom attributes are created by BindingAdapter.

public class BindingAdapters {
    @BindingAdapter(value = {"rvItemLayout", "rvList", "rvOnItemClick"}, requireAll = false)
    public static void setRvAdapter(RecyclerView recyclerView, int rvItemLayout, List rvList, @Nullable OnItemClickListener onItemClickListener) {
        if (rvItemLayout != 0 && rvList != null && rvList.size() > 0)
            recyclerView.setAdapter(new GeneralAdapter(rvItemLayout, rvList, onItemClickListener));
    }
}

Now from Activity, you pass list, click listener like

HomeActivity.java

public class HomeActivity extends AppCompatActivity {
    ActivityHomeBinding binding;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        binding = DataBindingUtil.setContentView(this, R.layout.activity_home);
        binding.setListOne(new ArrayList()); // pass your list or set list from response of API
        binding.setListTwo(new ArrayList());
        binding.setOnItemClickListenerOne(new OnItemClickListener() {
            @Override
            public void onItemClick(View view, Object object) {
                if (object instanceof ModelParent) {
                    // TODO: your action here
                }
            }
        });
        binding.setOnItemClickListenerTwo(new OnItemClickListener() {
            @Override
            public void onItemClick(View view, Object object) {
                if (object instanceof ModelChild) {
                    // TODO: your action here  
                }
            }
        });
    }
}

You don't want read too much, directly clone/download full example on from my github repo. And try it yourself.

You can see GeneralAdapter.java in above repo.

If you have problems while setting up data binding, please see this answer.

In case that the solution doesn't work, you have to enable Windows Authentication in iss manager. How to do that:

1.To start IIS Manager from the Run dialog box: On the Start menu, click All Programs, click Accessories, and then click Run. In the Open box, type inetmgr and then click OK.

2.In the Connections pane, expand the server name, expand Sites, and go to the level in the hierarchy pane that you want to configure, and then click the Web site or Web application. 3. Scroll to the IIS section in the Home pane, and then double-click Authentication.

4.In the Authentication pane, select Anonymous Authentication, and then click Disable.

5. In the Authentication pane, select Windows Authentication, and then click Enable.

Reference

The problem is not with extract, which can certainly handle 'military time'. It looks like you have a default timestamp format which has HH instead of HH24; or at least that's the only way I can see to recreate this:

SQL> select value from nls_session_parameters
  2  where parameter = 'NLS_TIMESTAMP_FORMAT';

VALUE
--------------------------------------------------------------------------------
DD-MON-RR HH24.MI.SSXFF

SQL> select extract(hour from cast(to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS')
  2  as timestamp)) from dual;

EXTRACT(HOURFROMCAST(TO_CHAR(SYSDATE,'DD-MON-YYYYHH24:MI:SS')ASTIMESTAMP))
--------------------------------------------------------------------------
                                                                        15

alter session set nls_timestamp_format = 'DD-MON-YYYY HH:MI:SS';

Session altered.

SQL> select extract(hour from cast(to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS')
  2  as timestamp)) from dual;

select extract(hour from cast(to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS') as timestamp)) from dual
                              *
ERROR at line 1:
ORA-01849: hour must be between 1 and 12

So the simple 'fix' is to set the format to something that does recognise 24-hours:

SQL> alter session set nls_timestamp_format = 'DD-MON-YYYY HH24:MI:SS';

Session altered.

SQL> select extract(hour from cast(to_char(sysdate, 'DD-MON-YYYY HH24:MI:SS')
  2  as timestamp)) from dual;

EXTRACT(HOURFROMCAST(TO_CHAR(SYSDATE,'DD-MON-YYYYHH24:MI:SS')ASTIMESTAMP))
--------------------------------------------------------------------------
                                                                        15

Although you don't need the to_char at all:

SQL> select extract(hour from cast(sysdate as timestamp)) from dual;

EXTRACT(HOURFROMCAST(SYSDATEASTIMESTAMP))
-----------------------------------------
                                       15

Fetching data with either null and value on where conditions are very tricky. Even if you are using straight Where and OrWhereNotNull condition then for every rows you will fetch both items ignoring other where conditions if applied. For example if you have more where conditions it will mask out those and still return with either null or value items because you used orWhere condition

The best way so far I found is as follows. This works as where (whereIn Or WhereNotNull)

Code::where(function ($query) {
            $query->where('to_be_used_by_user_id', '!=' , 2)->orWhereNull('to_be_used_by_user_id');                  
        })->get();

Prior to 0.20.203, and officially deprecated in 2.6.0:

hadoop fs -dus [directory]

Since 0.20.203 (dead link) 1.0.4 and still compatible through 2.6.0:

hdfs dfs -du [-s] [-h] URI [URI …]

You can also run hadoop fs -help for more info and specifics.

If you'd rather use xpath and that span is the only span below your div, use my example below. I'd recommend using CSS (see sircapsalot's post).

String kk = wd.findElement(By.xpath(//*[@id='customSelect_3']//span)).getText();

css example:

String kk = wd.findElement(By.cssSelector("div[id='customSelect_3'] span[class='selectLabel clear']")).getText();

Append a semicolon to the following line to fix the issue.

font-family:    Arial, Helvetica, sans-serif;

>>>list(map(int, str(number)))  #number is a given integer

It returns a list of all digits of number.

git tag -n99

Short and sweet. This will list up to 99 lines from each tag annotation/commit message. Here is a link to the official documentation for git tag.

I now think the limitation of only showing up to 99 lines per tag is actually a good thing as most of the time, if there were really more than 99 lines for a single tag, you wouldn't really want to see all the rest of the lines would you? If you did want to see more than 99 lines per tag, you could always increase this to a larger number.

I mean, I guess there could be a specific situation or reason to want to see massive tag messages, but at what point do you not want to see the whole message? When it has more than 999 lines? 10,000? 1,000,000? My point is, it typically makes sense to have a cap on how many lines you would see, and this number allows you to set that.

Since I am making an argument for what you generally want to see when looking at your tags, it probably makes sense to set something like this as an alias (from Iulian Onofrei's comment below):

git config --global alias.tags 'tag -n99'

I mean, you don't really want to have to type in git tag -n99 every time you just want to see your tags do you? Once that alias is configured, whenever you want to see your tags, you would just type git tags into your terminal. Personally, I prefer to take things a step further than this and create even more abbreviated bash aliases for all my commonly used commands. For that purpose, you could add something like this to your .bashrc file (works on Linux and similar environments):

alias gtag='git tag -n99'

Then whenever you want to see your tags, you just type gtag. Another advantage of going down the alias path (either git aliases or bash aliases or whatever) is you now have a spot already in place where you can add further customizations to how you personally, generally want to have your tags shown to you (like sorting them in certain ways as in my comment below, etc). Once you get over the hurtle of creating your first alias, you will now realize how easy it is to create more of them for other things you like to work in a customized way, like git log, but let's save that one for a different question/answer.

tl;dr

java.time.temporal.ChronoUnit.DAYS.between( 
    earlier.toLocalDate(), 
    later.toLocalDate() 
)

…or…

java.time.temporal.ChronoUnit.HOURS.between( 
    earlier.truncatedTo( ChronoUnit.HOURS )  , 
    later.truncatedTo( ChronoUnit.HOURS ) 
)

java.time

FYI, the Joda-Time project is now in maintenance mode, with the team advising migration to the java.time classes.

The equivalent of Joda-Time DateTime is ZonedDateTime.

ZoneId z = ZoneId.of( "Pacific/Auckland" ) ;
ZonedDateTime now = ZonedDateTime.now( z ) ;

Apparently you want to count the days by dates, meaning you want to ignore the time of day. For example, starting a minute before midnight and ending a minute after midnight should result in a single day. For this behavior, extract a LocalDate from your ZonedDateTime. The LocalDate class represents a date-only value without time-of-day and without time zone.

LocalDate localDateStart = zdtStart.toLocalDate() ;
LocalDate localDateStop = zdtStop.toLocalDate() ;

Use the ChronoUnit enum to calculate elapsed days or other units.

long days = ChronoUnit.DAYS.between( localDateStart , localDateStop ) ;

Truncate

As for you asking about a more general way to do this counting where you are interested the delta of hours as hour-of-the-clock rather than complete hours as spans-of-time of sixty minutes, use the truncatedTo method.

Here is your example of 14:45 to 15:12 on same day.

ZoneId z = ZoneId.of( "America/Montreal" ); 
ZonedDateTime start = ZonedDateTime.of( 2017 , 1 , 17 , 14 , 45 , 0 , 0 , z );
ZonedDateTime stop = ZonedDateTime.of( 2017 , 1 , 17 , 15 , 12 , 0 , 0 , z );

long hours = ChronoUnit.HOURS.between( start.truncatedTo( ChronoUnit.HOURS ) , stop.truncatedTo( ChronoUnit.HOURS ) );

1

This does not work for days. Use toLocalDate() in this case.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Short answer is: use recursion.

You can create one method and call that method right inside the same method recursively:

public class factorial {

    public static void main(String[] args) {
        System.out.println(calc(10));
    }

    public static long calc(long n) {
        if (n <= 1)
            return 1;
        else
            return n * calc(n - 1);
    }
}

Guava Documentation

The JDK provides Collections.unmodifiableXXX methods, but in our opinion, these can be unwieldy and verbose; unpleasant to use everywhere you want to make defensive copies unsafe: the returned collections are only truly immutable if nobody holds a reference to the original collection inefficient: the data structures still have all the overhead of mutable collections, including concurrent modification checks, extra space in hash tables, etc.

Of course there is! Win CMD can do a lot more than just split text files :)

Split a text file into separate files of 'max' lines each:

Split text file (max lines each):
: Initialize
set input=file.txt
set max=10000

set /a line=1 >nul
set /a file=1 >nul
set out=!file!_%input%
set /a max+=1 >nul

echo Number of lines in %input%:
find /c /v "" < %input%

: Split file
for /f "tokens=* delims=[" %i in ('type "%input%" ^| find /v /n ""') do (

if !line!==%max% (
set /a line=1 >nul
set /a file+=1 >nul
set out=!file!_%input%
echo Writing file: !out!
)

REM Write next file
set a=%i
set a=!a:*]=]!
echo:!a:~1!>>out!
set /a line+=1 >nul
)

If above code hangs or crashes, this example code splits files faster (by writing data to intermediate files instead of keeping everything in memory):

eg. To split a file with 7,600 lines into smaller files of maximum 3000 lines.

1. Generate regexp string/pattern files with set command to be fed to /g flag of findstr

list1.txt

\[[0-9]\]
\[[0-9][0-9]\]
\[[0-9][0-9][0-9]\]
\[[0-2][0-9][0-9][0-9]\]

list2.txt

\[[3-5][0-9][0-9][0-9]\]

list3.txt

\[[6-9][0-9][0-9][0-9]\]

2. Split the file into smaller files:

type "%input%" | find /v /n "" | findstr /b /r /g:list1.txt > file1.txt
type "%input%" | find /v /n "" | findstr /b /r /g:list2.txt > file2.txt
type "%input%" | find /v /n "" | findstr /b /r /g:list3.txt > file3.txt

3. remove prefixed line numbers for each file split:
   eg. for the 1st file:

for /f "tokens=* delims=[" %i in ('type "%cd%\file1.txt"') do (
set a=%i
set a=!a:*]=]!
echo:!a:~1!>>file_1.txt)

Notes:
Works with leading whitespace, blank lines & whitespace lines.

Tested on Win 10 x64 CMD, on 4.4GB text file, 5651982 lines.

Adapted from a grep in python.

Accepts a list of filenames via [2:], does no exception handling:

#!/usr/bin/env python
import re, sys, os

for f in filter(os.path.isfile, sys.argv[2:]):
    for line in open(f).readlines():
        if re.match(sys.argv[1], line):
            print line

sys.argv[1] resp sys.argv[2:] works, if you run it as an standalone executable, meaning

chmod +x

first

In my case I was doing this:

double a = (double) (MAX_BANDWIDTH_SHARED_MB/(qCount+1));

Instead of the "correct" :

double a = (double)MAX_BANDWIDTH_SHARED_MB/(qCount+1);

Take attention with the parentheses !

If anyone comes here after me, this is the answer that worked for me.

NOTE: please make to read the comments before using this, this not complete. The best advice for update queries I can give is to switch to SqlServer ;)

update mytable t
set z = (
  with comp as (
    select b.*, 42 as computed 
    from mytable t 
    where bs_id = 1
  )
  select c.computed
  from  comp c
  where c.id = t.id
)

Good luck,

GJ

You could do something like this:

//outside of main
namespace A
{
    enum A
    {
        a = 0,
        b = 69,
        c = 666
    };
};

//in main:

A::A a = A::c;
std::cout << a << std::endl;

I prefer TIMESTAMPDIFF because you can easily change the unit if need be.

FileInfo.Length will return the length of file, in bytes (not size on disk), so this is what you are looking for, I think.

You don't need JavaScript for this at all; just set the title attribute:

<div title="Hello, World!">
  <label>Name</label>
  <input type="text"/>
</div>

Note that the visual presentation of the tooltip is browser/OS dependent, so it might fade in and it might not. However, this is the semantic way to do tooltips, and it will work correctly with accessibility software like screen readers.

Demo in Stack Snippets

<div title="Hello, World!">_x000D_
  <label>Name</label>_x000D_
  <input type="text"/>_x000D_
</div>

This code needs to be put inside Run SQL query/queries on database

SQL QUERY WINDOW

As a general rule, when on Debian or Ubuntu and you're missing a development file (or any other file for that matter), use apt-file to figure out which package provides that file:

~ apt-file search openssl/bio.h
android-libboringssl-dev: /usr/include/android/openssl/bio.h
libssl-dev: /usr/include/openssl/bio.h
libwolfssl-dev: /usr/include/cyassl/openssl/bio.h
libwolfssl-dev: /usr/include/wolfssl/openssl/bio.h

A quick glance at each of the packages that are returned by the command, using apt show will tell you which among the packages is the one you're looking for:

The map function does not exist on the Object.prototype however you can emulate it like so

var myMap = function ( obj, callback ) {

    var result = {};

    for ( var key in obj ) {
        if ( Object.prototype.hasOwnProperty.call( obj, key ) ) {
            if ( typeof callback === 'function' ) {
                result[ key ] = callback.call( obj, obj[ key ], key, obj );
            }
        }
    }

    return result;

};

var myObject = { 'a': 1, 'b': 2, 'c': 3 };

var newObject = myMap( myObject, function ( value, key ) {
    return value * value;
});

Answer

You need to create a header with a proper formatted User agent String, it server to communicate client-server.

You can check your own user agent Here.

Example

Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:47.0) Gecko/20100101 Firefox/47.0
Mozilla/5.0 (Macintosh; Intel Mac OS X x.y; rv:42.0) Gecko/20100101 Firefox/42.0

Third party Package user_agent 0.1.9

I found this module very simple to use, in one line of code it randomly generates a User agent string.

from user_agent import generate_user_agent, generate_navigator
from pprint import pprint

print(generate_user_agent())
# 'Mozilla/5.0 (compatible; MSIE 8.0; Windows NT 6.3; Win64; x64)'

print(generate_user_agent(os=('mac', 'linux')))
# 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:36.0) Gecko/20100101 Firefox/36.0'

pprint(generate_navigator())

# {'app_code_name': 'Mozilla',
#  'app_name': 'Netscape',
#  'appversion': '5.0',
#  'name': 'firefox',
#  'os': 'linux',
#  'oscpu': 'Linux i686 on x86_64',
#  'platform': 'Linux i686 on x86_64',
#  'user_agent': 'Mozilla/5.0 (X11; Ubuntu; Linux i686 on x86_64; rv:41.0) Gecko/20100101 Firefox/41.0',
#  'version': '41.0'}

pprint(generate_navigator_js())

# {'appCodeName': 'Mozilla',
#  'appName': 'Netscape',
#  'appVersion': '38.0',
#  'platform': 'MacIntel',
#  'userAgent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:38.0) Gecko/20100101 Firefox/38.0'}

if you can get the proper response in your localhost and getting this error kind of error and if you are using nginx.

1. Go to Server and open nginx.conf with :

   nano etc/nginx/nginx.conf

2. Add following line in http block :

   proxy_buffering off;

3. Save and exit the file

This solved my issue

Another option is to check if the last digit is an even number :

$value = "1024";// A Number
$even = array(0, 2, 4, 6, 8);
if(in_array(substr($value, -1),$even)){
  // Even Number
}else{
  // Odd Number
}

Or to make it faster, use isset() instead of array_search :

$value = "1024";// A Number
$even = array(0 => 1, 2 => 1, 4 => 1, 6 => 1, 8 => 1);
if(isset($even[substr($value, -1)]){
  // Even Number
}else{
  // Odd Number
}

Or to make it more faster (beats mod operator at times) :

$even = array(0, 2, 4, 6, 8);
if(in_array(substr($number, -1),$even)){
  // Even Number
}else{
  // Odd Number
}

Here is the time test as a proof to my findings.

To anyone who is still interested in this question: If: 1-decodeByteArray returns null 2-Base64.decode throws bad-base64 Exception

Here is the solution: -You should consider the value sent to you from API is Base64 Encoded and should be decoded first in order to cast it to a Bitmap object! -Take a look at your Base64 encoded String, If it starts with

data:image/jpg;base64

The Base64.decode won't be able to decode it, So it has to be removed from your encoded String:

final String encodedString = "data:image/jpg;base64, ....";                        
final String pureBase64Encoded = encodedString.substring(encodedString.indexOf(",")  + 1);

Now the pureBase64Encoded object is ready to be decoded:

final byte[] decodedBytes = Base64.decode(pureBase64Encoded, Base64.DEFAULT);

Now just simply use the line below to turn this into a Bitmap Object! :

Bitmap decodedBitmap = BitmapFactory.decodeByteArray(decodedBytes, 0, decodedBytes.length);

Or if you're using the great library Glide:

Glide.with(CaptchaFragment.this).load(decodedBytes).crossFade().fitCenter().into(mCatpchaImageView);

This should do the job! It wasted one day on this and came up to this solution!

Note: If you are still getting bad-base64 error consider other Base64.decode flags like Base64.URL_SAFE and so on

Expanding on what leucos said in his answer, you can also print information with Ansible's humble debug module:

- hosts: all
  gather_facts: no
  tasks:
    - shell: ps -eo pcpu,user,args | sort -r -k1 | head -n5
      register: ps

    # Print the shell task's stdout.
    - debug: msg={{ ps.stdout }}

    # Print all contents of the shell task's output.
    - debug: var=ps

Is this what you want:

>>> d={'a':1,'b':2,'c':3}
>>> default_val=99
>>> for k in d:
...     d[k]=default_val
...     
>>> d
{'a': 99, 'b': 99, 'c': 99}

It must be synchronized, using an object lock, stateless, or immutable.

First of all you use here two strings: "" marks a string it may be ""-empty "s"- string of lenght 1 or "aaa" string of lenght 3, while '' marks chars . In order to be able to do String str = "a" + "aaa" + 'a' you must use method Character.toString(char c) as @Thomas Keene said so an example would be String str = "a" + "aaa" + Character.toString('a')

Step 1 - Getting the URL Right

Many of the answers here were valid until recently. For now, the ONLY supported param is url, and the new share link is as follows...

https://www.linkedin.com/sharing/share-offsite/?url={url}

Make sure url is encoded, using something like fixedEncodeURIComponent().

Source: Official Microsoft.com Linkedin Share Plugin Documentation. All LinkedIn.com links for developer documentation appear to be blank pages now -- perhaps related to the acquisition of LinkedIn by Microsoft.

Step 2 - Setting Custom Parameters (Title, Image, Summary, etc.)

Once upon a time, you could use these params: title, summary, source. But if you look closely at all of the documentation, there is actually still a way to still set summary, title, etc.! Put these in the <head> block of the page you want to share...

• <meta property='og:title' content='Title of the article"/>
• <meta property='og:image' content='//media.example.com/ 1234567.jpg"/>
• <meta property='og:description' content='Description that will show in the preview"/>
• <meta property='og:url' content='//www.example.com/URL of the article" />

Then LinkedIn will use these! Source: LinkedIn Developer Docs: Making Your Website Shareable on LinkedIn.

Step 3 - Verifying LinkedIn Share Results

Not sure you did everything right? Take the URL of the page you are sharing (i.e., example.com, not linkedin.com/share?url=example.com), and input that URL into the following: LinkedIn Post Inspector. This will tell you everything about how your URL is being shared!

This also pulls/invalidates the current cache of your page, and then refreshes it (in case you have a stuck, cached version of your page in LinkedIn's database). Because it pulls the cache, then refreshes it, sometimes it's best to use the LinkedIn Post Inspector twice, and use the second result as the expected output.

Still not sure? Here's an online demo I built with 20+ social share services. Inspect the source code and find out for yourself how exactly the LinkedIn sharing is working.

Want More Social Sharing Services?

I have been maintaining a Github Repo that's been tracking social-share URL formats since 2012, check it out: Github: Social Share URLs.

Why not join in on all the social share url's?

Automatic garbage collection is a process where the JVM gets rid of or keeps certain data points in memory to ultimately free up space for the running program. Memory is first sent to heap memory, that is where the garbage collector (GC) does its work, then is decided to be terminated or kept. Java assumes that the programmer cannot always be trusted, so it terminates items it thinks it doesn't need.

Probably the simplest way is to use the InputBox method of the Microsoft.VisualBasic.Interaction class:

[void][Reflection.Assembly]::LoadWithPartialName('Microsoft.VisualBasic')

$title = 'Demographics'
$msg   = 'Enter your demographics:'

$text = [Microsoft.VisualBasic.Interaction]::InputBox($msg, $title)

Send a ajax request to your server like this in your js and get your result in success function.

jQuery.ajax({
            url: "/rest/abc",
            type: "GET",

            contentType: 'application/json; charset=utf-8',
            success: function(resultData) {
                //here is your json.
                  // process it

            },
            error : function(jqXHR, textStatus, errorThrown) {
            },

            timeout: 120000,
        });

at server side send response as json type.

And you can use jQuery.getJSON for your application.

The block approach avoids running the lookup algorithm for every key:

[dict enumerateKeysAndObjectsUsingBlock:^(id key, id value, BOOL* stop) {
  NSLog(@"%@ => %@", key, value);
}];

Even though NSDictionary is implemented as a hashtable (which means that the cost of looking up an element is O(1)), lookups still slow down your iteration by a constant factor.

My measurements show that for a dictionary d of numbers ...

NSMutableDictionary* dict = [NSMutableDictionary dictionary];
for (int i = 0; i < 5000000; ++i) {
  NSNumber* value = @(i);
  dict[value.stringValue] = value;
}

... summing up the numbers with the block approach ...

__block int sum = 0;
[dict enumerateKeysAndObjectsUsingBlock:^(NSString* key, NSNumber* value, BOOL* stop) {
  sum += value.intValue;
}];

... rather than the loop approach ...

int sum = 0;
for (NSString* key in dict)
  sum += [dict[key] intValue];

... is about 40% faster.

EDIT: The new SDK (6.1+) appears to optimise loop iteration, so the loop approach is now about 20% faster than the block approach, at least for the simple case above.

Works fine for me in 5.0.27

I just get a warning (not an error) that the table exists;

Bound method = instance method

Unbound method = static method.

Edit: the api call has been removed by google. so it is no longer functioning.

Agree with Pareshkumar's answer. Now there is a python wrapper googlefinance for the url call.

Install googlefinance

$pip install googlefinance

It is easy to get current stock price:

>>> from googlefinance import getQuotes
>>> import json
>>> print json.dumps(getQuotes('AAPL'), indent=2)
[
  {
    "Index": "NASDAQ", 
    "LastTradeWithCurrency": "129.09", 
    "LastTradeDateTime": "2015-03-02T16:04:29Z", 
    "LastTradePrice": "129.09", 
    "Yield": "1.46", 
    "LastTradeTime": "4:04PM EST", 
    "LastTradeDateTimeLong": "Mar 2, 4:04PM EST", 
    "Dividend": "0.47", 
    "StockSymbol": "AAPL", 
    "ID": "22144"
  }
]

Google finance is a source that provides real-time stock data. There are also other APIs from yahoo, such as yahoo-finance, but they are delayed by 15min for NYSE and NASDAQ stocks.

On Windows make sure your Windows firewall is correctly configure / disabled. I had to disable the Windows firewall (because I didn't bother with configuring it) to get things to work even when I was testing with localhost.

My suggestion:

$http({
    method: 'DELETE',
    url: '/roles/' + roleid,
    data: {
        user: userId
    },
    headers: {
        'Content-type': 'application/json;charset=utf-8'
    }
})
.then(function(response) {
    console.log(response.data);
}, function(rejection) {
    console.log(rejection.data);
});

One liner

In case you want to paste it in quickly...

document.cookie.split(";").forEach(function(c) { document.cookie = c.replace(/^ +/, "").replace(/=.*/, "=;expires=" + new Date().toUTCString() + ";path=/"); });

And the code for a bookmarklet :

javascript:(function(){document.cookie.split(";").forEach(function(c) { document.cookie = c.replace(/^ +/, "").replace(/=.*/, "=;expires=" + new Date().toUTCString() + ";path=/"); }); })();

Use-

<span ng-bind-html="myContent"></span>

You need to tell angular to not escape it.

Use the force, read the source (excerpt from the Priority and Level class compiled, TRACE level was introduced in version 1.2.12):

public final static int OFF_INT = Integer.MAX_VALUE;
public final static int FATAL_INT = 50000;
public final static int ERROR_INT = 40000;
public final static int WARN_INT  = 30000;
public final static int INFO_INT  = 20000;
public final static int DEBUG_INT = 10000;
public static final int TRACE_INT = 5000; 
public final static int ALL_INT = Integer.MIN_VALUE; 

or the log4j API for the Level class, which makes it quite clear.

When the library decides whether to print a certain statement or not, it computes the effective level of the responsible Logger object (based on configuration) and compares it with the LogEvent's level (depends on which method was used in the code – trace/debug/.../fatal). If LogEvent's level is greater or equal to the Logger's level, the LogEvent is sent to appender(s) – "printed". At the core, it all boils down to an integer comparison and this is where these constants come to action.

Thanks all for your help! Finally I used JQuery/AJAX as you suggested, passing the parameter using model.

So, in JS:

$('#divPoints').load('/Schedule/UpdatePoints', UpdatePointsAction);
var points= $('#newpoints').val();
$element.find('PointsDiv').html("You have" + points+ " points");

In Controller:

var model = _newPoints;
return PartialView(model);

In View

<div id="divPoints"></div>
@Html.Hidden("newpoints", Model)

--save-dev: Package will appear in your devDependencies.

According to the npm install docs.

If someone is planning on downloading and using your module in their program, then they probably don't want or need to download and build the external test or documentation framework that you use.

In other words, when you run npm install, your project's devDependencies will be installed, but the devDependencies for any packages that your app depends on will not be installed; further, other apps having your app as a dependency need not install your devDependencies. Such modules should only be needed when developing the app (eg grunt, mocha etc).

According to the package.json docs

Edit: Attempt at visualising what npm install does:

• yourproject
  • dependency installed
    • dependency installed
      • dependency installed
      • devDependency NOT installed
    • devDependency NOT installed
  • devDependency installed
    • dependency installed
    • devDependency NOT installed

This error may happen when mapping variables you defined in REST definition do not match with @PathVariable names.

Example: Suppose you defined in the REST definition

@GetMapping(value = "/{appId}", produces = "application/json", consumes = "application/json")

Then during the definition of the function, it should be

public ResponseEntity<List> getData(@PathVariable String appId)

This error may occur when you use any other variable other than defined in the REST controller definition with @PathVariable. Like, the below code will raise the error as ID is different than appId variable name:

public ResponseEntity<List> getData(@PathVariable String ID)

A pointer pointing to a memory location that has been deleted (or freed) is called dangling pointer.

#include <stdlib.h>
#include <stdio.h> 
 void  main()
 {
    int *ptr = (int *)malloc(sizeof(int));
    // After below free call, ptr becomes a 
    // dangling pointer
    free(ptr); 
 }

find . -size +10000k -exec ls -sd {} +

If your version of find won't accept the + notation (which acts rather like xargs does), then you might use (GNU find and xargs, so find probably supports + anyway):

find . -size +10000k -print0 | xargs -0 ls -sd

or you might replace the + with \; (and live with the relative inefficiency of this), or you might live with problems caused by spaces in names and use the portable:

find . -size +10000k -print | xargs ls -sd

The -d on the ls commands ensures that if a directory is ever found (unlikely, but...), then the directory information will be printed, not the files in the directory. And, if you're looking for files more than 1 MB (as a now-deleted comment suggested), you need to adjust the +10000k to 1000k or maybe +1024k, or +2048 (for 512-byte blocks, the default unit for -size). This will list the size and then the file name. You could avoid the need for -d by adding -type f to the find command, of course.

To remove - Can't perform a React state update on an unmounted component warning, use componentDidMount method under a condition and make false that condition on componentWillUnmount method. For example : -

class Home extends Component {
  _isMounted = false;

  constructor(props) {
    super(props);

    this.state = {
      news: [],
    };
  }

  componentDidMount() {
    this._isMounted = true;

    ajaxVar
      .get('https://domain')
      .then(result => {
        if (this._isMounted) {
          this.setState({
            news: result.data.hits,
          });
        }
      });
  }

  componentWillUnmount() {
    this._isMounted = false;
  }

  render() {
    ...
  }
}

  imagePicker(){_x000D_
        this.refs.fileUploader.click();_x000D_
        this.setState({_x000D_
            imagePicker: true_x000D_
        })_x000D_
    }

  <div onClick={this.imagePicker.bind(this)} >_x000D_
  <input type='file'  style={{display: 'none'}}  ref="fileUploader" onChange={this.imageOnChange} /> _x000D_
  </div>

This work for me

The easiest solution is to create a new workspace in eclipse/STS.

File -> Switch Workspace -> Others...

I'd recommend to use an array for storing all values via __set().

class foo {

    protected $values = array();

    public function __get( $key )
    {
        return $this->values[ $key ];
    }

    public function __set( $key, $value )
    {
        $this->values[ $key ] = $value;
    }

}

This way you make sure, that you can't access the variables in another way (note that $values is protected), to avoid collisions.

You can accomplish this using man-in-the-middle techniques with dynamic SSL generation. Take a look at mitmproxy - it's a Python based, SSL-capable MITM proxy.

1. Can someone give a simple definition of what Record is?

A Record<K, T> is an object type whose property keys are K and whose property values are T. That is, keyof Record<K, T> is equivalent to K, and Record<K, T>[K] is (basically) equivalent to T.

2. Is Record<K,T> merely a way of saying "all properties on this object will have type T"? Probably not all objects, since K has some purpose...

As you note, K has a purpose... to limit the property keys to particular values. If you want to accept all possible string-valued keys, you could do something like Record<string, T>, but the idiomatic way of doing that is to use an index signature like { [k: string]: T }.

3. Does the K generic forbid additional keys on the object that are not K, or does it allow them and just indicate that their properties are not transformed to T?

It doesn't exactly "forbid" additional keys: after all, a value is generally allowed to have properties not explicitly mentioned in its type... but it wouldn't recognize that such properties exist:

declare const x: Record<"a", string>;
x.b; // error, Property 'b' does not exist on type 'Record<"a", string>'

and it would treat them as excess properties which are sometimes rejected:

declare function acceptR(x: Record<"a", string>): void;
acceptR({a: "hey", b: "you"}); // error, Object literal may only specify known properties

and sometimes accepted:

const y = {a: "hey", b: "you"};
acceptR(y); // okay

4. With the given example:

   type ThreeStringProps = Record<'prop1' | 'prop2' | 'prop3', string>
   

   Is it exactly the same as this?:

   type ThreeStringProps = {prop1: string, prop2: string, prop3: string}
   

Yes!

Hope that helps. Good luck!

Official document of Crypto++ AES is a good start. And from my archive, a basic implementation of AES is as follows:

Please refer here with more explanation, I recommend you first understand the algorithm and then try to understand each line step by step.

#include <iostream>
#include <iomanip>

#include "modes.h"
#include "aes.h"
#include "filters.h"

int main(int argc, char* argv[]) {

    //Key and IV setup
    //AES encryption uses a secret key of a variable length (128-bit, 196-bit or 256-   
    //bit). This key is secretly exchanged between two parties before communication   
    //begins. DEFAULT_KEYLENGTH= 16 bytes
    CryptoPP::byte key[ CryptoPP::AES::DEFAULT_KEYLENGTH ], iv[ CryptoPP::AES::BLOCKSIZE ];
    memset( key, 0x00, CryptoPP::AES::DEFAULT_KEYLENGTH );
    memset( iv, 0x00, CryptoPP::AES::BLOCKSIZE );

    //
    // String and Sink setup
    //
    std::string plaintext = "Now is the time for all good men to come to the aide...";
    std::string ciphertext;
    std::string decryptedtext;

    //
    // Dump Plain Text
    //
    std::cout << "Plain Text (" << plaintext.size() << " bytes)" << std::endl;
    std::cout << plaintext;
    std::cout << std::endl << std::endl;

    //
    // Create Cipher Text
    //
    CryptoPP::AES::Encryption aesEncryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
    CryptoPP::CBC_Mode_ExternalCipher::Encryption cbcEncryption( aesEncryption, iv );

    CryptoPP::StreamTransformationFilter stfEncryptor(cbcEncryption, new CryptoPP::StringSink( ciphertext ) );
    stfEncryptor.Put( reinterpret_cast<const unsigned char*>( plaintext.c_str() ), plaintext.length() );
    stfEncryptor.MessageEnd();

    //
    // Dump Cipher Text
    //
    std::cout << "Cipher Text (" << ciphertext.size() << " bytes)" << std::endl;

    for( int i = 0; i < ciphertext.size(); i++ ) {

        std::cout << "0x" << std::hex << (0xFF & static_cast<CryptoPP::byte>(ciphertext[i])) << " ";
    }

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

    //
    // Decrypt
    //
    CryptoPP::AES::Decryption aesDecryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
    CryptoPP::CBC_Mode_ExternalCipher::Decryption cbcDecryption( aesDecryption, iv );

    CryptoPP::StreamTransformationFilter stfDecryptor(cbcDecryption, new CryptoPP::StringSink( decryptedtext ) );
    stfDecryptor.Put( reinterpret_cast<const unsigned char*>( ciphertext.c_str() ), ciphertext.size() );
    stfDecryptor.MessageEnd();

    //
    // Dump Decrypted Text
    //
    std::cout << "Decrypted Text: " << std::endl;
    std::cout << decryptedtext;
    std::cout << std::endl << std::endl;

    return 0;
}

For installation details :

• How do I install Crypto++ in Visual Studio 2010 Windows 7?
• *nix environment
• For Ubuntu I did:

sudo apt-get install libcrypto++-dev libcrypto++-doc libcrypto++-utils

Do you merely want to print the string that way, or do you want that to be the internal representation of the string? If the latter, create it as a raw string by prefixing it with r: r"Hello\tWorld\nHello World".

>>> a = r"Hello\tWorld\nHello World"
>>> a # in the interpreter, this calls repr()
'Hello\\tWorld\\nHello World'
>>> print a
Hello\tWorld\nHello World

Also, \s is not an escape character, except in regular expressions, and then it still has a much different meaning than what you're using it for.

Try Stretch="UniformToFill" on the Image

To expand on previous answers, a function to do this could work like this (changing the time and interval formats however you like them according to this for function.date, and this for DateInterval):

(I've also written an alternate form of the below function here.)

// Return adjusted time.

function addMinutesToTime( $time, $plusMinutes ) {

    $time = DateTime::createFromFormat( 'g:i:s', $time );
    $time->add( new DateInterval( 'PT' . ( (integer) $plusMinutes ) . 'M' ) );
    $newTime = $time->format( 'g:i:s' );

    return $newTime;
}

$adjustedTime = addMinutesToTime( '9:15:00', 15 );

echo '<h1>Adjusted Time: ' . $adjustedTime . '</h1>' . PHP_EOL . PHP_EOL;

Wrapping it with div should work. I tested it in Firefox, Chrome on Fedora 13 (demo).

#content {
   width: 95%;
   height: 95%;
   margin: auto;
}

#myCanvas {
   width: 100%;
   height: 100%;
   border: 1px solid black;
}

And the canvas should be enclosed in tag

<div id="content">
    <canvas id="myCanvas">Your browser doesn't support canvas tag</canvas>
</div>

Let me know if it works. Cheers.

Only uninstalling (sudo apt-get purge) libpq-dev and re-installing it worked for me.

I am running Ubuntu 19.04 and followed all the instructions above and then some. Finally, what worked for me was to run

sudo apt autoremove rvm

and now when I try and reinstall RVM it's actually gone. RVM is invasive, to say the least.

Unless things have changed, you're better off with

public static ByteBuffer str_to_bb(String msg, Charset charset){
    return ByteBuffer.wrap(msg.getBytes(charset));
}

public static String bb_to_str(ByteBuffer buffer, Charset charset){
    byte[] bytes;
    if(buffer.hasArray()) {
        bytes = buffer.array();
    } else {
        bytes = new byte[buffer.remaining()];
        buffer.get(bytes);
    }
    return new String(bytes, charset);
}

Usually buffer.hasArray() will be either always true or always false depending on your use case. In practice, unless you really want it to work under any circumstances, it's safe to optimize away the branch you don't need.

Only to supplement:

1. dir() is the most powerful/fundamental tool. (Most recommended)

2. Solutions other than dir() merely provide their way of dealing the output of dir().

   Listing 2nd level attributes or not, it is important to do the sifting by yourself, because sometimes you may want to sift out internal vars with leading underscores __, but sometimes you may well need the __doc__ doc-string.

3. __dir__() and dir() returns identical content.
4. __dict__ and dir() are different. __dict__ returns incomplete content.

5. IMPORTANT: __dir__() can be sometimes overwritten with a function, value or type, by the author for whatever purpose.

   Here is an example:

   \\...\\torchfun.py in traverse(self, mod, search_attributes)
   445             if prefix in traversed_mod_names:
   446                 continue
   447             names = dir(m)
   448             for name in names:
   449                 obj = getattr(m,name)
   

   TypeError: descriptor __dir__ of 'object' object needs an argument

   The author of PyTorch modified the __dir__() method to something that requires an argument. This modification makes dir() fail.

6. If you want a reliable scheme to traverse all attributes of an object, do remember that every pythonic standard can be overridden and may not hold, and every convention may be unreliable.

Solution #1 (Older) (not recommended)

Firstly install ffmpeg-php project (http://ffmpeg-php.sourceforge.net/)

And then you can use of this simple code:

<?php
$frame = 10;
$movie = 'test.mp4';
$thumbnail = 'thumbnail.png';

$mov = new ffmpeg_movie($movie);
$frame = $mov->getFrame($frame);
if ($frame) {
    $gd_image = $frame->toGDImage();
    if ($gd_image) {
        imagepng($gd_image, $thumbnail);
        imagedestroy($gd_image);
        echo '<img src="'.$thumbnail.'">';
    }
}
?>

Description: This project use binary extension .so file, It's very old and last update was for 2008. So, maybe don't works with newer version of FFMpeg or PHP.

Solution #2 (Update 2018) (recommended)

Firstly install PHP-FFMpeg project (https://github.com/PHP-FFMpeg/PHP-FFMpeg)
(just run for install: composer require php-ffmpeg/php-ffmpeg)

And then you can use of this simple code:

<?php

Description: It's newer and more modern project and works with latest version of FFMpeg and PHP. Note that it's required to proc_open() PHP function.

This can happen also when you have identical function names on different routes.

First, add a textView in the XML file

<TextView  
    android:id="@+id/rate_id"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/what_U_want_to_display_in_first_time"
    />

then add a button in xml file with id btn_change_textView and write this two line of code in onCreate() method of activity

Button btn= (Button) findViewById(R.id. btn_change_textView);
TextView textView=(TextView)findViewById(R.id.rate_id);

then use clickListener() on button object like this

btn.setOnClickListener(new View.OnClickListener {
    public void onClick(View v) {
      
        textView.setText("write here what u want to display after button click in string");
    }
});

Go to AndroidManifest.xml in the root folder of your project and change the Activity name which you want to execute first.

Example:

<activity android:name=".put your started activity name here"
          android:label="@string/app_name">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

When you use intellij also look at:

File -> Project Structure -> Project

File -> Project Structure -> Modules

When you have multiple modules make sure you set the correct language level in the module tab.

I'm a friend of keeping the original files, so that you can still use the archived original ones and do new encodes from these fresh ones when the old transcodes are out of date. eg. migrating them from previously transocded mpeg2-hd to mpeg4-hd (and perhaps from mpeg4-hd to its successor in sometime). but all of these should be done from the original. any compression step will followed by a loss of quality. it will need some time to redo this again, but in my opinion it's worth the effort.

so, if you want to keep the originals, you can use the running time in seconds of you tapes times the maximum datarate of hdv (constants 27mbit/s I think) to get your needed storage capacity

You can do it this way also:

import pandas as pd
import os

new_df = pd.DataFrame()
for r, d, f in os.walk(csv_folder_path):
    for file in f:
        complete_file_path = csv_folder_path+file
        read_file = pd.read_csv(complete_file_path)
        new_df = new_df.append(read_file, ignore_index=True)


new_df.shape

I´ve got this error, when implementing an library with following AndroidmManifest.xml

<provider
        android:name="androidx.core.content.FileProvider"
        android:authorities="library.path.provider"
        android:exported="false"
        android:grantUriPermissions="true">

            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/provider_paths"/>
    </provider>

I solved this when i put following Code in Project AndroidManifest.xml (app/src/main):

<provider
        android:name="androidx.core.content.FileProvider"
        android:authorities="${applicationId}.provider"
        android:exported="false"
        android:grantUriPermissions="true"
        tools:replace="android:authorities">

I'm using Assembly.GetExecutingAssembly().Location to get the path to a ClickOnce deployed application in .Net 4.5.1.

However, you shouldn't write to any folder where your application is deployed to ever, regardless of deployment method (xcopy, ClickOnce, InstallShield, anything) because those are usually read only for applications, especially in newer Windows versions and server environments.

An app must always write to the folders reserved for such purposes. You can get the folders you need starting from Environment.SpecialFolder Enumeration. The MSDN page explains what each folder is for: http://msdn.microsoft.com/en-us/library/system.environment.specialfolder.aspx

I.e. for data, logs and other files one can use ApplicationData (roaming), LocalApplicationData (local) or CommonApplicationData. For temporary files use Path.GetTempPath or Path.GetTempFileName.

The above work on servers and desktops too.

EDIT: Assembly.GetExecutingAssembly() is called in main executable.

Since you have a DataTable already, and since I am assuming you are using SQL Server 2008 or better, this is probably the most straightforward way. First, in your database, create the following two objects:

CREATE TYPE dbo.MyDataTable -- you can be more speciifc here
AS TABLE
(
  col1 INT,
  col2 DATETIME
  -- etc etc. The columns you have in your data table.
);
GO

CREATE PROCEDURE dbo.InsertMyDataTable
  @dt AS dbo.MyDataTable READONLY
AS
BEGIN
  SET NOCOUNT ON;

  INSERT dbo.RealTable(column list) SELECT column list FROM @dt;
END
GO

Now in your C# code:

DataTable tvp = new DataTable();
// define / populate DataTable

using (connectionObject)
{
    SqlCommand cmd = new SqlCommand("dbo.InsertMyDataTable", connectionObject);
    cmd.CommandType = CommandType.StoredProcedure;
    SqlParameter tvparam = cmd.Parameters.AddWithValue("@dt", tvp);
    tvparam.SqlDbType = SqlDbType.Structured;
    cmd.ExecuteNonQuery();
}

If you had given more specific details in your question, I would have given a more specific answer.

There may be several reasons Java does not generally use the IUser convention.

1. Part of the Object-Oriented approach is that you should not have to know whether the client is using an interface or an implementation class. So, even List is an interface and String is an actual class, a method might be passed both of them - it doesn't make sense to visually distinguish the interfaces.

2. In general, we will actually prefer the use of interfaces in client code (prefer List to ArrayList, for instance). So it doesn't make sense to make the interfaces stand out as exceptions.

3. The Java naming convention prefers longer names with actual meanings to Hungarian-style prefixes. So that code will be as readable as possible: a List represents a list, and a User represents a user - not an IUser.

PHP is likely the easiest.

Just make a file script.php that contains <?php shell_exec("yourscript.sh"); ?> and send anybody who clicks the button to that destination. You can return the user to the original page with header:

<?php
shell_exec("yourscript.sh");
header('Location: http://www.website.com/page?success=true');
?>

Reference: http://php.net/manual/en/function.shell-exec.php

Thank you, in PostgreSQL this works for boolean

SELECT
hat,
shoe,
boat,
false as placeholder
FROM
objects

You can add a JAR which having above specified class exist e.g.ojdbc jar which supported by installed java version, also make sure that you have added it into classpath.

If you want a TRIE implemented as a Python class, here is something I wrote after reading about them:

class Trie:

    def __init__(self):
        self.__final = False
        self.__nodes = {}

    def __repr__(self):
        return 'Trie<len={}, final={}>'.format(len(self), self.__final)

    def __getstate__(self):
        return self.__final, self.__nodes

    def __setstate__(self, state):
        self.__final, self.__nodes = state

    def __len__(self):
        return len(self.__nodes)

    def __bool__(self):
        return self.__final

    def __contains__(self, array):
        try:
            return self[array]
        except KeyError:
            return False

    def __iter__(self):
        yield self
        for node in self.__nodes.values():
            yield from node

    def __getitem__(self, array):
        return self.__get(array, False)

    def create(self, array):
        self.__get(array, True).__final = True

    def read(self):
        yield from self.__read([])

    def update(self, array):
        self[array].__final = True

    def delete(self, array):
        self[array].__final = False

    def prune(self):
        for key, value in tuple(self.__nodes.items()):
            if not value.prune():
                del self.__nodes[key]
        if not len(self):
            self.delete([])
        return self

    def __get(self, array, create):
        if array:
            head, *tail = array
            if create and head not in self.__nodes:
                self.__nodes[head] = Trie()
            return self.__nodes[head].__get(tail, create)
        return self

    def __read(self, name):
        if self.__final:
            yield name
        for key, value in self.__nodes.items():
            yield from value.__read(name + [key])

You could use isnull function to get both null and empty values of a text field:

SELECT * FROM myTable
WHERE isnull(my_nullable_text_field,'') = ''

Changing the port in Device Manager works for me. I was also able to fix it by finding the port that Arduino was using and then select it from the Adruion IDE from tools menu Tools>Port>Com Port

Try this:

Html Markup

<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl="#">HyperLink</asp:HyperLink>

Code

using System.Drawing;
using System.Web.UI;
using System.Web.UI.WebControls;

protected void Page_Load(object sender, EventArgs e)
{
    Style style = new Style();
    style.ForeColor = Color.Green;
    this.Page.Header.StyleSheet.CreateStyleRule(style, this, "#" + HyperLink1.ClientID + ":hover");
}

If you installed postresql on your server then just host: localhost to database.yml, I usually throw it in around where it says pool: 5. Otherwise if it's not localhost definitely tell that app where to find its database.

development:
  adapter: postgresql
  encoding: unicode
  database: kickrstack_development
  host: localhost
  pool: 5
  username: kickrstack
  password: secret

Make sure your user credentials are set correctly by creating a database and assigning ownership to your app's user to establish the connection. To create a new user in postgresql 9 run:

sudo -u postgres psql

set the postgresql user password if you haven't, it's just backslash password.

postgres=# \password

Create a new user and password and the user's new database:

postgres=# create user "guy_on_stackoverflow" with password 'keepitonthedl';
postgres=# create database "dcaclab_development" owner "guy_on_stackoverflow"; 

Now update your database.yml file after you've confirmed creating the database, user, password and set these privileges. Don't forget host: localhost.

Celery won't import the task if the app was to lack some of its dependencies. For instance, an app.view imports numpy without it being installed. Best way to check for this is to try to run your django server, as you probably know:

python manage.py runserver

You have found the problem if this raises ImportErrors within the app that has houses the respective task. Just pip install everything, or try to remove the dependencies and try again. This isn't the cause of your issue otherwise.

Vertical alignment only works on inline elements. If you float it, then I don't think it is treated as part of that stream of inline elements any more.

Make the label an inline-block, and use vertical alignment on both the label and the input to align their middles. Then, assuming it is okay to have a specific width on the labels and checkboxes, use relative positioning instead of floating to swap them (jsFiddle demo):

input {
    width: 20px;

    position: relative;
    left: 200px;

    vertical-align: middle;
}

label {  
    width: 200px;

    position: relative;
    left: -20px;

    display: inline-block;
    vertical-align: middle;
}

Into the Preferences > Setting - Default

You will have the next by default:

// Display file encoding in the status bar
    "show_encoding": false

You could change it or like cdesmetz said set your user settings.

Undefined offset means there's an empty array key for example:

$a = array('Felix','Jon','Java');

// This will result in an "Undefined offset" because the size of the array
// is three (3), thus, 0,1,2 without 3
echo $a[3];

You can solve the problem using a loop (while):

$i = 0;
while ($row = mysqli_fetch_assoc($result)) {
    // Increase count by 1, thus, $i=1
    $i++;

    $groupname[$i] = base64_decode(base64_decode($row['groupname']));

    // Set the first position of the array to null or empty
    $groupname[0] = "";
}

It got this error because I had managed to clobber jdk1.8.0_60 with the jre!

How do I determine the size of an object in Python?

The answer, "Just use sys.getsizeof", is not a complete answer.

That answer does work for builtin objects directly, but it does not account for what those objects may contain, specifically, what types, such as custom objects, tuples, lists, dicts, and sets contain. They can contain instances each other, as well as numbers, strings and other objects.

A More Complete Answer

Using 64-bit Python 3.6 from the Anaconda distribution, with sys.getsizeof, I have determined the minimum size of the following objects, and note that sets and dicts preallocate space so empty ones don't grow again until after a set amount (which may vary by implementation of the language):

Python 3:

Empty
Bytes  type        scaling notes
28     int         +4 bytes about every 30 powers of 2
37     bytes       +1 byte per additional byte
49     str         +1-4 per additional character (depending on max width)
48     tuple       +8 per additional item
64     list        +8 for each additional
224    set         5th increases to 736; 21nd, 2272; 85th, 8416; 341, 32992
240    dict        6th increases to 368; 22nd, 1184; 43rd, 2280; 86th, 4704; 171st, 9320
136    func def    does not include default args and other attrs
1056   class def   no slots 
56     class inst  has a __dict__ attr, same scaling as dict above
888    class def   with slots
16     __slots__   seems to store in mutable tuple-like structure
                   first slot grows to 48, and so on.

How do you interpret this? Well say you have a set with 10 items in it. If each item is 100 bytes each, how big is the whole data structure? The set is 736 itself because it has sized up one time to 736 bytes. Then you add the size of the items, so that's 1736 bytes in total

Some caveats for function and class definitions:

Note each class definition has a proxy __dict__ (48 bytes) structure for class attrs. Each slot has a descriptor (like a property) in the class definition.

Slotted instances start out with 48 bytes on their first element, and increase by 8 each additional. Only empty slotted objects have 16 bytes, and an instance with no data makes very little sense.

Also, each function definition has code objects, maybe docstrings, and other possible attributes, even a __dict__.

Also note that we use sys.getsizeof() because we care about the marginal space usage, which includes the garbage collection overhead for the object, from the docs:

getsizeof() calls the object’s __sizeof__ method and adds an additional garbage collector overhead if the object is managed by the garbage collector.

Also note that resizing lists (e.g. repetitively appending to them) causes them to preallocate space, similarly to sets and dicts. From the listobj.c source code:

    /* This over-allocates proportional to the list size, making room
     * for additional growth.  The over-allocation is mild, but is
     * enough to give linear-time amortized behavior over a long
     * sequence of appends() in the presence of a poorly-performing
     * system realloc().
     * The growth pattern is:  0, 4, 8, 16, 25, 35, 46, 58, 72, 88, ...
     * Note: new_allocated won't overflow because the largest possible value
     *       is PY_SSIZE_T_MAX * (9 / 8) + 6 which always fits in a size_t.
     */
    new_allocated = (size_t)newsize + (newsize >> 3) + (newsize < 9 ? 3 : 6);

Historical data

Python 2.7 analysis, confirmed with guppy.hpy and sys.getsizeof:

Bytes  type        empty + scaling notes
24     int         NA
28     long        NA
37     str         + 1 byte per additional character
52     unicode     + 4 bytes per additional character
56     tuple       + 8 bytes per additional item
72     list        + 32 for first, 8 for each additional
232    set         sixth item increases to 744; 22nd, 2280; 86th, 8424
280    dict        sixth item increases to 1048; 22nd, 3352; 86th, 12568 *
120    func def    does not include default args and other attrs
64     class inst  has a __dict__ attr, same scaling as dict above
16     __slots__   class with slots has no dict, seems to store in 
                    mutable tuple-like structure.
904    class def   has a proxy __dict__ structure for class attrs
104    old class   makes sense, less stuff, has real dict though.

Note that dictionaries (but not sets) got a more compact representation in Python 3.6

I think 8 bytes per additional item to reference makes a lot of sense on a 64 bit machine. Those 8 bytes point to the place in memory the contained item is at. The 4 bytes are fixed width for unicode in Python 2, if I recall correctly, but in Python 3, str becomes a unicode of width equal to the max width of the characters.

And for more on slots, see this answer.

A More Complete Function

We want a function that searches the elements in lists, tuples, sets, dicts, obj.__dict__'s, and obj.__slots__, as well as other things we may not have yet thought of.

We want to rely on gc.get_referents to do this search because it works at the C level (making it very fast). The downside is that get_referents can return redundant members, so we need to ensure we don't double count.

Classes, modules, and functions are singletons - they exist one time in memory. We're not so interested in their size, as there's not much we can do about them - they're a part of the program. So we'll avoid counting them if they happen to be referenced.

We're going to use a blacklist of types so we don't include the entire program in our size count.

import sys
from types import ModuleType, FunctionType
from gc import get_referents

# Custom objects know their class.
# Function objects seem to know way too much, including modules.
# Exclude modules as well.
BLACKLIST = type, ModuleType, FunctionType


def getsize(obj):
    """sum size of object & members."""
    if isinstance(obj, BLACKLIST):
        raise TypeError('getsize() does not take argument of type: '+ str(type(obj)))
    seen_ids = set()
    size = 0
    objects = [obj]
    while objects:
        need_referents = []
        for obj in objects:
            if not isinstance(obj, BLACKLIST) and id(obj) not in seen_ids:
                seen_ids.add(id(obj))
                size += sys.getsizeof(obj)
                need_referents.append(obj)
        objects = get_referents(*need_referents)
    return size

To contrast this with the following whitelisted function, most objects know how to traverse themselves for the purposes of garbage collection (which is approximately what we're looking for when we want to know how expensive in memory certain objects are. This functionality is used by gc.get_referents.) However, this measure is going to be much more expansive in scope than we intended if we are not careful.

For example, functions know quite a lot about the modules they are created in.

Another point of contrast is that strings that are keys in dictionaries are usually interned so they are not duplicated. Checking for id(key) will also allow us to avoid counting duplicates, which we do in the next section. The blacklist solution skips counting keys that are strings altogether.

Whitelisted Types, Recursive visitor (old implementation)

To cover most of these types myself, instead of relying on the gc module, I wrote this recursive function to try to estimate the size of most Python objects, including most builtins, types in the collections module, and custom types (slotted and otherwise).

This sort of function gives much more fine-grained control over the types we're going to count for memory usage, but has the danger of leaving types out:

import sys
from numbers import Number
from collections import Set, Mapping, deque

try: # Python 2
    zero_depth_bases = (basestring, Number, xrange, bytearray)
    iteritems = 'iteritems'
except NameError: # Python 3
    zero_depth_bases = (str, bytes, Number, range, bytearray)
    iteritems = 'items'

def getsize(obj_0):
    """Recursively iterate to sum size of object & members."""
    _seen_ids = set()
    def inner(obj):
        obj_id = id(obj)
        if obj_id in _seen_ids:
            return 0
        _seen_ids.add(obj_id)
        size = sys.getsizeof(obj)
        if isinstance(obj, zero_depth_bases):
            pass # bypass remaining control flow and return
        elif isinstance(obj, (tuple, list, Set, deque)):
            size += sum(inner(i) for i in obj)
        elif isinstance(obj, Mapping) or hasattr(obj, iteritems):
            size += sum(inner(k) + inner(v) for k, v in getattr(obj, iteritems)())
        # Check for custom object instances - may subclass above too
        if hasattr(obj, '__dict__'):
            size += inner(vars(obj))
        if hasattr(obj, '__slots__'): # can have __slots__ with __dict__
            size += sum(inner(getattr(obj, s)) for s in obj.__slots__ if hasattr(obj, s))
        return size
    return inner(obj_0)

And I tested it rather casually (I should unittest it):

>>> getsize(['a', tuple('bcd'), Foo()])
344
>>> getsize(Foo())
16
>>> getsize(tuple('bcd'))
194
>>> getsize(['a', tuple('bcd'), Foo(), {'foo': 'bar', 'baz': 'bar'}])
752
>>> getsize({'foo': 'bar', 'baz': 'bar'})
400
>>> getsize({})
280
>>> getsize({'foo':'bar'})
360
>>> getsize('foo')
40
>>> class Bar():
...     def baz():
...         pass
>>> getsize(Bar())
352
>>> getsize(Bar().__dict__)
280
>>> sys.getsizeof(Bar())
72
>>> getsize(Bar.__dict__)
872
>>> sys.getsizeof(Bar.__dict__)
280

This implementation breaks down on class definitions and function definitions because we don't go after all of their attributes, but since they should only exist once in memory for the process, their size really doesn't matter too much.

/var/lib/tomcat5.5/webapps/spaghetti/WEB-INF/lib/jsp-api-6.0.16.jar
/var/lib/tomcat5.5/webapps/spaghetti/WEB-INF/lib/servlet-api-6.0.16.jar

You should not have any server-specific libraries in the /WEB-INF/lib. Leave them in the appserver's own library. It would only lead to collisions in the classpath. Get rid of all appserver-specific libraries in /WEB-INF/lib (and also in JRE/lib and JRE/lib/ext if you have placed any of them there).

A common cause that the appserver-specific libraries are included in the webapp's library is that starters think that it is the right way to fix compilation errors of among others the javax.servlet classes not being resolveable. Putting them in webapp's library is the wrong solution. You should reference them in the classpath during compilation, i.e. javac -cp /path/to/server/lib/servlet.jar and so on, or if you're using an IDE, you should integrate the server in the IDE and associate the web project with the server. The IDE will then automatically take server-specific libraries in the classpath (buildpath) of the webapp project.

You should follow the guidelines on Add a secondary horizontal axis:

Add a secondary horizontal axis

To complete this procedure, you must have a chart that displays a secondary vertical axis. To add a secondary vertical axis, see Add a secondary vertical axis.

1. Click a chart that displays a secondary vertical axis. This displays the Chart Tools, adding the Design, Layout, and Format tabs.

2. On the Layout tab, in the Axes group, click Axes.

   

3. Click Secondary Horizontal Axis, and then click the display option that you want.

Add a secondary vertical axis

You can plot data on a secondary vertical axis one data series at a time. To plot more than one data series on the secondary vertical axis, repeat this procedure for each data series that you want to display on the secondary vertical axis.

1. In a chart, click the data series that you want to plot on a secondary vertical axis, or do the following to select the data series from a list of chart elements:

   • Click the chart.

     This displays the Chart Tools, adding the Design, Layout, and Format tabs.

   • On the Format tab, in the Current Selection group, click the arrow in the Chart Elements box, and then click the data series that you want to plot along a secondary vertical axis.

     

2. On the Format tab, in the Current Selection group, click Format Selection. The Format Data Series dialog box is displayed.

   Note: If a different dialog box is displayed, repeat step 1 and make sure that you select a data series in the chart.

3. On the Series Options tab, under Plot Series On, click Secondary Axis and then click Close.

   A secondary vertical axis is displayed in the chart.

4. To change the display of the secondary vertical axis, do the following:

   • On the Layout tab, in the Axes group, click Axes.

   • Click Secondary Vertical Axis, and then click the display option that you want.

5. To change the axis options of the secondary vertical axis, do the following:

   • Right-click the secondary vertical axis, and then click Format Axis.

   • Under Axis Options, select the options that you want to use.

If the element is position absolutely, then it isn't relative, or in reference to any object - including the page itself. So margin: auto; can't decide where the middle is.

Its waiting to be told explicitly, using left and top where to position itself.

You can still center it programatically, using javascript or somesuch.

Add this line in your manifest:

I see Federico you've found solution by yourself. The problem was in two places. Assignations need proper quoting, in your case

SOME_PATH="/$COMPANY/someProject/some path"

is one of possible solutions.

But in shell those quotes are not stored in a memory, so when you want to use this variable, you need to quote it again, for example:

NEW_VAR="$SOME_PATH"

because if not, space will be expanded to command level, like this:

NEW_VAR=/YourCompany/someProject/some path

which is not what you want.

Not Found Exceptions

Sometimes you may wish to throw an exception if a model is not found. This is particularly useful in routes or controllers. The findOrFail and firstOrFail methods will retrieve the first result of the query. However, if no result is found, a Illuminate\Database\Eloquent\ModelNotFoundException will be thrown:

$model = App\Flight::findOrFail(1);

$model = App\Flight::where('legs', '>', 100)->firstOrFail();

If the exception is not caught, a 404 HTTP response is automatically sent back to the user. It is not necessary to write explicit checks to return 404 responses when using these methods:

Route::get('/api/flights/{id}', function ($id) {
    return App\Flight::findOrFail($id);
});

I couldn't get the compiler (x64 version) to use the sysroot until I added SET(CMAKE_SYSROOT $ENV{HOME}/raspberrypi/rootfs) to pi.cmake.

If you installed IIS after the .Net framework you can solve the porblem by re-installing the .Net framework. Part of its install detects whether IIS is present and updates IIS accordingly.

Although micahtan's answer is good, it won't work in a static method. If you want to retrieve the name of the current type, this one should work everywhere:

string className = MethodBase.GetCurrentMethod().DeclaringType.Name;

Use this:

window.open('', '_self');

This only works in chrome; it is a bug. It will be fixed in the future, so use this hacky solution with this in mind.

Yes, throwing an exception from the failed constructor is the standard way of doing this. Read this FAQ about Handling a constructor that fails for more information. Having a init() method will also work, but everybody who creates the object of mutex has to remember that init() has to be called. I feel it goes against the RAII principle.

Try applying following style to your spinner using

style="@style/SpinnerTheme"

//Spinner Style:

<style name="SpinnerTheme" parent="android:Widget.Spinner">
    <item name="android:background">@drawable/bg_spinner</item>
</style>

//bg_spinner.xml Replace the arrow_down_gray with your arrow

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item>

        <layer-list>

            <item>
                <shape>
                    <gradient android:angle="90" android:endColor="#ffffff" android:startColor="#ffffff" android:type="linear" />

                    <stroke android:width="0.33dp" android:color="#0fb1fa" />

                    <corners android:radius="0dp" />

                    <padding android:bottom="3dp" android:left="3dp" android:right="3dp" android:top="3dp" />
                </shape>
            </item>

            <item android:right="5dp">

                <bitmap android:gravity="center_vertical|right" android:src="@drawable/arrow_down_gray" />

            </item>

        </layer-list>

    </item>

</selector>

Here is a link talking about how to do this, it should be what you are looking for:

http://sixrevisions.com/css/how-to-create-inset-typography-with-css3/

Let your callback return false and pass that on to the onclick handler:

<a href="#" onclick="return callmymethod(24)">Call</a>

function callmymethod(myVal){
    //doing custom things with myVal
    //here I want to prevent default
    return false;
}

To create maintainable code, however, you should abstain from using "inline Javascript" (i.e.: code that's directly within an element's tag) and modify an element's behavior via an included Javascript source file (it's called unobtrusive Javascript).

The mark-up:

<a href="#" id="myAnchor">Call</a>

The code (separate file):

// Code example using Prototype JS API
$('myAnchor').observe('click', function(event) {
    Event.stop(event); // suppress default click behavior, cancel the event
    /* your onclick code goes here */
});

BETWEEN (Transact-SQL)

Specifies a(n) (inclusive) range to test.

test_expression [ NOT ] BETWEEN begin_expression AND end_expression

Arguments

test_expression

Is the expression to test for in the range defined by begin_expression and end_expression. test_expression must be the same data type as both begin_expression and end_expression.

NOT

Specifies that the result of the predicate be negated.

begin_expression

Is any valid expression. begin_expression must be the same data type as both test_expression and end_expression.

end_expression

Is any valid expression. end_expression must be the same data type as both test_expression and begin_expression.

AND

Acts as a placeholder that indicates test_expression should be within the range indicated by begin_expression and end_expression.

Remarks

To specify an exclusive range, use the greater than (>) and less than operators (<). If any input to the BETWEEN or NOT BETWEEN predicate is NULL, the result is UNKNOWN.

Result Value

BETWEEN returns TRUE if the value of test_expression is greater than or equal to the value of begin_expression and less than or equal to the value of end_expression.

NOT BETWEEN returns TRUE if the value of test_expression is less than the value of begin_expression or greater than the value of end_expression.

put these in values/colors.xml

<resources>
    <color name="light_font">#FBFBFB</color>
    <color name="grey_font">#ff9e9e9e</color>
    <color name="text_shadow">#7F000000</color>
    <color name="text_shadow_white">#FFFFFF</color>
</resources>

Then in your layout xml here are some example TextView's

Example of Floating text on Light with Dark shadow

<TextView android:id="@+id/txt_example1"
                  android:layout_width="wrap_content"
                  android:layout_height="wrap_content"
                  android:textSize="14sp"
                  android:textStyle="bold"
                  android:textColor="@color/light_font"
                  android:shadowColor="@color/text_shadow"
                  android:shadowDx="1"
                  android:shadowDy="1"
                  android:shadowRadius="2" />

Example of Etched text on Light with Dark shadow

<TextView android:id="@+id/txt_example2"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textSize="14sp"
                android:textStyle="bold"
                android:textColor="@color/light_font"
                android:shadowColor="@color/text_shadow"
                android:shadowDx="-1"
                android:shadowDy="-1"
                android:shadowRadius="1" />

Example of Crisp text on Light with Dark shadow

<TextView android:id="@+id/txt_example3"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textSize="14sp"
                android:textStyle="bold"
                android:textColor="@color/grey_font"
                android:shadowColor="@color/text_shadow_white"
                android:shadowDx="-2"
                android:shadowDy="-2"
                android:shadowRadius="1" />

Notice the positive and negative values... I suggest to play around with the colors/values yourself but ultimately you can adjust these settings to get the effect your looking for.
