It seems things have changed in recent versions of the CLI (I'm using 6.0.1). I was able to change the default port used by ng serve by adding a port option to my project's angular.json:

{
    "$schema": "./node_modules/@angular/cli/lib/config/schema.json",
    "projects": {
        "my-project": {
            "architect": {
                "serve": {
                    "options": {
                        "port": 4201
                    }
                }
            }
        }
    }
}

(Only relevant properties are shown in this example.)

default port of mysql is 3306

default pot of sql server is 1433

Better late than never!

Caveat!

The conversions occur from left to right.

Try this:

int i = 3, j = 2;
double k = 33;
cout << k * j / i << endl; // prints 22
cout << j / i * k << endl; // prints 0

I managed to get a good result with the following sequence (run Matlab twice at the beginning):

h = gcf; % Current figure handle
set(h,'Resize','off');
set(h,'PaperPositionMode','manual');
set(h,'PaperPosition',[0 0 9 6]);
set(h,'PaperUnits','centimeters');
set(h,'PaperSize',[9 6]); % IEEE columnwidth = 9cm
set(h,'Position',[0 0 9 6]);
% xpos, ypos must be set
txlabel = text(xpos,ypos,'$$[\mathrm{min}]$$','Interpreter','latex','FontSize',9);

% Dump colored encapsulated PostScript
print('-depsc2','-loose', 'signals');

It might also make sense to add a call to clearNotifications in applicationDidBecomeActive so that in case the application is in the background and comes back it will also clear the notifications.

- (void)applicationDidBecomeActive:(UIApplication *)application
{
    [self clearNotifications];
}

In the definition of your Card class, a declaration for a default construction appears:

class Card
{
    // ...

    Card(); // <== Declaration of default constructor!

    // ...
};

But no corresponding definition is given. In fact, this function definition (from card.cpp):

void Card() {
//nothing
}

Does not define a constructor, but rather a global function called Card that returns void. You probably meant to write this instead:

Card::Card() {
//nothing
}

Unless you do that, since the default constructor is declared but not defined, the linker will produce error about undefined references when a call to the default constructor is found.

The same applies to your constructor accepting two arguments. This:

void Card(Card::Rank rank, Card::Suit suit) {
    cardRank = rank;
    cardSuit = suit;
}

Should be rewritten into this:

Card::Card(Card::Rank rank, Card::Suit suit) {
    cardRank = rank;
    cardSuit = suit;
}

And the same also applies for other member functions: it seems you did not add the Card:: qualifier before the member function names in their definitions. Without it, those functions are global functions rather than definitions of member functions.

Your destructor, on the other hand, is declared but never defined. Just provide a definition for it in card.cpp:

Card::~Card() { }

I had this error when I had specified fromGroupName instead of formArrayName.

Make sure you correctly specify if it is a form array or form group.

<div formGroupName="formInfo"/>

<div formArrayName="formInfo"/>

Sample 1: This works and produces Exit code = 0. That is Good. Note the "." , directly after echo.

C:\Users\phife.dog\gitrepos\1\repo_abc\scripts #
@echo.| set /p JUNK_VAR=This is a message displayed like Linux echo -n would display it ... & echo %ERRORLEVEL%

This is a message displayed like Linux echo -n would display it ... 0

Sample 2: This works but produces Exit code = 1. That is Bad. Please note the lack of ".", after echo. That appears to be the difference.

C:\Users\phife.dog\gitrepos\1\repo_abc\scripts #
@echo | set /p JUNK_VAR=This is a message displayed like Linux echo -n would display it ... & echo %ERRORLEVEL%

This is a message displayed like Linux echo -n would display it ... 1

use it:

.CopyToDataTable()

example:

string _sqlWhere = "Nachname = 'test'";
string _sqlOrder = "Nachname DESC";

DataTable _newDataTable = yurDateTable.Select(_sqlWhere, _sqlOrder).CopyToDataTable();

I found that using the latest version will fix this problem:

So,

Steps to follow in order to import a JAR sucesfully to your project using Android Studio 0.1.1:

• Download the library.jar file and copy it to your /libs/ folder inside your application project.
• Open the build.gradle file and edit your dependencies to include the new .jar file:

compile files('libs/android-support-v4.jar', 'libs/GoogleAdMobAdsSdk-6.4.1.jar')

• File -> Close Project
• Open a command prompt on your project's root location, i.e 'C:\Users\Username\AndroidStudioProjects\MyApplicationProject\'
• On the command prompt, type gradlew clean, wait till it's done.
• Reopen your application project in Android Studio.
• Test run your application and it should work succesfully.

The numpy_indexed package (disclaimer: I am its author) contains functionality to efficiently perform operations of this type:

import numpy_indexed as npi
print(npi.group_by(np.digitize(data, bins)).mean(data))

This is essentially the same solution as the one I posted earlier; but now wrapped in a nice interface, with tests and all :)

add and remove methods are easier to use. They update the data in the list and call notifyDataSetChanged in background.

Sample code:

adapter.add("your object");
adapter.remove("your object");

You can generate Application Encryption Key using this command:

php artisan key:generate

Then, create a cache file for faster configuration loading using this command:

php artisan config:cache

Or, serve the application on the PHP development server using this command:

php artisan serve

That's it!

You can also use Ghostscript to merge different PDFs. You can even use it to merge a mix of PDFs, PostScript (PS) and EPS into one single output PDF file:

gs \
  -o merged.pdf \
  -sDEVICE=pdfwrite \
  -dPDFSETTINGS=/prepress \
   input_1.pdf \
   input_2.pdf \
   input_3.eps \
   input_4.ps \
   input_5.pdf

However, I agree with other answers: for your use case of merging PDF file types only, pdftk may be the best (and certainly fastest) option.

Update:
If processing time is not the main concern, but if the main concern is file size (or a fine-grained control over certain features of the output file), then the Ghostscript way certainly offers more power to you. To highlight a few of the differences:

• Ghostscript can 'consolidate' the fonts of the input files which leads to a smaller file size of the output. It also can re-sample images, or scale all pages to a different size, or achieve a controlled color conversion from RGB to CMYK (or vice versa) should you need this (but that will require more CLI options than outlined in above command).
• pdftk will just concatenate each file, and will not convert any colors. If each of your 16 input PDFs contains 5 subsetted fonts, the resulting output will contain 80 subsetted fonts. The resulting PDF's size is (nearly exactly) the sum of the input file bytes.

You are looking for the greatest common divisor (GCD).

You can calculate it recursively in VBA, like this:

Function GCD(numerator As Integer, denominator As Integer)
  If denominator = 0 Then
    GCD = numerator
  Else
    GCD = GCD(denominator, numerator Mod denominator)
  End If
End Function

And use it in your sheet like this:

   ColumnA   ColumnB   ColumnC
1  33        11        =A1/GCD(A1; B1) & ":" & B1/GCD(A1; B1)
2  25         5        =A2/GCD(A2; B2) & ":" & B2/GCD(A2; B2)

It is recommendable to store the result of the function call in a hidden column and use this result to avoid calling the function twice per row:

   ColumnA   ColumnB   ColumnC        ColumnD
1  33        11        =GCD(A1; B1)   =A1/C1 & ":" & B1/C1
2  25         5        =GCD(A2; B2)   =A2/C2 & ":" & B2/C2

If you're using Python 2.6 or newer you can use the grouper recipe from the itertools module:

from itertools import izip_longest

def grouper(n, iterable, fillvalue=None):
    "grouper(3, 'ABCDEFG', 'x') --> ABC DEF Gxx"
    args = [iter(iterable)] * n
    return izip_longest(fillvalue=fillvalue, *args)

Call like this:

for item1, item2 in grouper(2, l):
    # Do something with item1 and item2

Note that in Python 3.x you should use zip_longest instead of izip_longest.

quickjs should be the best option after quickjs come out. Just pip install quickjs and you are ready to go.

modify based on the example on README.

from quickjs import Function

js = """
function escramble_758(){
var a,b,c
a='+1 '
b='84-'
a+='425-'
b+='7450'
c='9'
document.write(a+c+b)
escramble_758()
}
"""

escramble_758 = Function('escramble_758', js.replace("document.write", "return "))

print(escramble_758())

https://github.com/PetterS/quickjs

It is really bad idea, but...

for x in range(0, 9):
    globals()['string%s' % x] = 'Hello'

and then for example:

print(string3)

will give you:

Hello

However this is bad practice. You should use dictionaries or lists instead, as others propose. Unless, of course, you really wanted to know how to do it, but did not want to use it.

For strings containing   I've had to double-decode the string. First decode would turn it into the second pass would correctly decode it to the expected character.

If you compile your project in jar file: you can put your file in resources/files/your_file.text or pdf;

and use this code:

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.io.*;

public class readFileService(){
    private static final Logger LOGGER = LoggerFactory.getLogger(readFileService.class);


    public byte[] getFile(){
        String filePath="/files/your_file";
        InputStream inputStreamFile;
        byte[] bytes;
        try{
            inputStreamFile = this.getClass().getResourceAsStream(filePath);
            bytes = new byte[inputStreamFile.available()];
            inputStreamFile.read(bytes);    
        } catch(NullPointerException | IOException e) {
            LOGGER.error("Erreur read file "+filePath+" error message :" +e.getMessage());
            return null;
        }
        return bytes;
    } 
}

revalidate is called on a container once new components are added or old ones removed. this call is an instruction to tell the layout manager to reset based on the new component list. revalidate will trigger a call to repaint what the component thinks are 'dirty regions.' Obviously not all of the regions on your JPanel are considered dirty by the RepaintManager.

repaint is used to tell a component to repaint itself. It is often the case that you need to call this in order to cleanup conditions such as yours.

Ctrl+A, Ctrl+K to wipe the current line in the terminal. You can then recall it with Ctrl+Y if you need.

You can remove public keyword from your functions, because, you have to define a class in order to declare public, private or protected function

you can do:

A = randi(10, [3 4]);      %# a random matrix
any( A(:)==5 )             %# does A contain 5?

To do the above in a vectorized way, use:

any( bsxfun(@eq, A(:), [5 7 11] )

or as @woodchips suggests:

ismember([5 7 11], A)

Since you mentioned ng-src and it seems as though you want the page to finish rendering before loading your image, you may modify jaime's answer to run the native directive after the browser finishes rendering.

This blog post explains this pretty well; essentially, you insert the $timeout wrapper for window.setTimeout before the callback function wherein you make those modifications to the CSS.

You cannot include style directives in GFM.

The most complete documentation/example is "Markdown Cheatsheet", and it illustrates that this element <style> is missing.

If you manage to include your text in one of the GFM elements, then you can play with a github.css stylesheet in order to colors that way, meaning to color using inline CSS style directives, referring to said css stylesheet.

Richard's answer is correct. Alternatively you can also create a MappingJsonFactory (in org.codehaus.jackson.map) which knows where to find ObjectMapper. The error you got was because the regular JsonFactory (from core package) has no dependency to ObjectMapper (which is in the mapper package).

But usually you just use ObjectMapper and do not worry about JsonParser or other low level components -- they will just be needed if you want to data-bind parts of stream, or do low-level handling.

Option 1-

You can try this-

$('#selectID').append($('<option>',
 {
    value: value_variable,
    text : text_variable
}));

Like this-

for (i = 0; i < 10; i++)_x000D_
{ _x000D_
     $('#mySelect').append($('<option>',_x000D_
     {_x000D_
        value: i,_x000D_
        text : "Option "+i _x000D_
    }));_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
<select id='mySelect'></select>

Option 2-

Or try this-

$('#selectID').append( '<option value="'+value_variable+'">'+text_variable+'</option>' );

Like this-

for (i = 0; i < 10; i++)_x000D_
{ _x000D_
     $('#mySelect').append( '<option value="'+i+'">'+'Option '+i+'</option>' );_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
<select id='mySelect'></select>

SVN seems to handle binary deltas more efficiently than Git.

I had to decide on a versioning system for documentation (JPEG files, PDF files, and .odt files). I just tested adding a JPEG file and rotating it 90 degrees four times (to check effectiveness of binary deltas). Git's repository grew 400%. SVN's repository grew by only 11%.

So it looks like SVN is much more efficient with binary files.

So my choice is Git for source code and SVN for binary files like documentation.

If you don't want to put @SuppressWarning("unchecked") on each sf.getEntries() call, you can always make a wrapper that will return List.

See this other question

Try

if (!(i == 'InvKey' || i == 'PostDate')) {

or

if (i != 'InvKey' || i != 'PostDate') {

that says if i does not equals InvKey OR PostDate

Everyone's versions do things a little different. This is the version that I have developed over the years. This version seems to account for all of the issues I have encountered. Simply populate a data set into a table then pass the table name to this stored procedure.

I call this stored procedure like this:

EXEC    @return_value = *DB_You_Create_The_SP_In*.[dbo].[Export_CSVFile]
        @DB = N'*YourDB*',
        @TABLE_NAME = N'*YourTable*',
        @Dir = N'*YourOutputDirectory*',
        @File = N'*YourOutputFileName*'

There are also two other variables:

• @NullBlanks -- This will take any field that doesn't have a value and null it. This is useful because in the true sense of the CSV specification each data point should have quotes around them. If you have a large data set this will save you a fair amount of space by not having "" (two double quotes) in those fields. If you don't find this useful then set it to 0.
• @IncludeHeaders -- I have one stored procedure for outputting CSV files, so I do have that flag in the event I don't want headers.

This will create the stored procedure:

CREATE PROCEDURE [dbo].[Export_CSVFile] 
(@DB varchar(128),@TABLE_NAME varchar(128), @Dir varchar(255), @File varchar(250),@NULLBLANKS bit=1,@IncludeHeader bit=1)
AS

Because the condition is never true. i.e. count !=100 never executes when you put count=count+3 or count =count+9. try this out..while count<100

I know when you said "contents" you didn't mean this, but if you want to find all the values of all the attributes of a webelement this is a pretty nifty way to do that with javascript in python:

everything = b.execute_script(
    'var element = arguments[0];'
    'var attributes = {};'
    'for (index = 0; index < element.attributes.length; ++index) {'
    '    attributes[element.attributes[index].name] = element.attributes[index].value };'
    'var properties = [];'
    'properties[0] = attributes;'
    'var element_text = element.textContent;'
    'properties[1] = element_text;'
    'var styles = getComputedStyle(element);'
    'var computed_styles = {};'
    'for (index = 0; index < styles.length; ++index) {'
    '    var value_ = styles.getPropertyValue(styles[index]);'
    '    computed_styles[styles[index]] = value_ };'
    'properties[2] = computed_styles;'
    'return properties;', element)

you can also get some extra data with element.__dict__.

I think this is about all the data you'd ever want to get from a webelement.

In my case I was using a third party library (i.e. vendor) and the library comes with a sample app which I already had install on my device. So that sample app was now conflicting each time I try to install my own app implementing the library. So I just uninstalled the vendor's sample app and it works afterwards.

you can just use element.remove()

I have done the same percentage calculator for one of my app where we need to show the percentage saved if you choose a "Yearly Plan" over the "Monthly Plan". It helps you to save a specific amount of money in the given period. I have used it for the subscriptions.

Monthly paid for a year - 2028 Yearly paid one time - 1699

1699 is a 16.22% decrease of 2028.

Formula: Percentage of decrease = |2028 - 1699|/2028 = 329/2028 = 0.1622 = 16.22%

I hope that helps someone looking for the same kind of implementation.

func calculatePercentage(monthly: Double, yearly: Double) -> Double {
    let totalMonthlyInYear = monthly * 12
    let result = ((totalMonthlyInYear-yearly)/totalMonthlyInYear)*100
    print("percentage is -",result)
    return result.rounded(toPlaces: 0)
}

Usage:

 let savingsPercentage = self.calculatePercentage(monthly: Double( monthlyProduct.price), yearly: Double(annualProduct.price))
 self.btnPlanDiscount.setTitle("Save \(Int(savingsPercentage))%",for: .normal)

The extension usage for rounding up the percentage over the Double:

extension Double {
/// Rounds the double to decimal places value
func rounded(toPlaces places:Int) -> Double {
    let divisor = pow(10.0, Double(places))
    return (self * divisor).rounded() / divisor
   }
}

I have attached the image for understanding the same.

Thanks

I use year 2000 instead of Epoch Time in my calculus. Working with smaller numbers is easy to store and transport and is JSON friendly.

Year 2000 was at second 946684800 of epoch time.

Year 2000 was at second 63082281600 from 1-st of Jan 0001.

DateTime.UtcNow Ticks starts from 1-st of Jan 0001

Seconds from year 2000:

DateTime.UtcNow.Ticks/10000000-63082281600

Seconds from Unix Time:

DateTime.UtcNow.Ticks/10000000-946684800

For example year 2020 is:

var year2020 = (new DateTime()).AddYears(2019).Ticks; // Because DateTime starts already at year 1

637134336000000000 Ticks since 1-st of Jan 0001

63713433600 Seconds since 1-st of Jan 0001

You shouldn't use String.match but RegExp.prototype.test (i.e. /abc/.test("abcd")) instead of String.search() if you're only interested in a boolean value. You also need to repeat your character class as explained in the answer by Andy E:

var regexp = /^[a-zA-Z0-9-_]+$/;

Use distinct-colors.

It generates a palette of visually distinct colors.

distinct-colors is highly configurable:

• Choose how many colors are in the palette
• Restrict the hue to a specific range
• Restrict the chroma (saturation) to a specific range
• Restrict the lightness to a specific range
• Configure general quality of the palette

You shouldn't be creating a new Random in method scope. Make it a class member:

public class Foo {
   private Random random 

   public Foo() {
       this(System.currentTimeMillis());
   }

   public Foo(long seed) {
       this.random = new Random(seed);
   }

   public synchronized double getNext() {
        return generator.nextDouble();
   }
}

This is only an example. I don't think wrapping Random this way adds any value. Put it in a class of yours that is using it.

It's entirely likely that a large portion of the developer base comes from a Java background where using == to compare strings is wrong and doesn't work.

In C# there's no (practical) difference (for strings) as long as they are typed as string.

If they are typed as object or T then see other answers here that talk about generic methods or operator overloading as there you definitely want to use the Equals method.

With Swift 3, JSONSerialization has a method called json?Object(with:?options:?). json?Object(with:?options:?) has the following declaration:

class func jsonObject(with data: Data, options opt: JSONSerialization.ReadingOptions = []) throws -> Any

Returns a Foundation object from given JSON data.

When you use json?Object(with:?options:?), you have to deal with error handling (try, try? or try!) and type casting (from Any). Therefore, you can solve your problem with one of the following patterns.

#1. Using a method that throws and returns a non-optional type

import Foundation

func convertToDictionary(from text: String) throws -> [String: String] {
    guard let data = text.data(using: .utf8) else { return [:] }
    let anyResult: Any = try JSONSerialization.jsonObject(with: data, options: [])
    return anyResult as? [String: String] ?? [:]
}

Usage:

let string1 = "{\"City\":\"Paris\"}"
do {
    let dictionary = try convertToDictionary(from: string1)
    print(dictionary) // prints: ["City": "Paris"]
} catch {
    print(error)
}

let string2 = "{\"Quantity\":100}"
do {
    let dictionary = try convertToDictionary(from: string2)
    print(dictionary) // prints [:]
} catch {
    print(error)
}

let string3 = "{\"Object\"}"
do {
    let dictionary = try convertToDictionary(from: string3)
    print(dictionary)
} catch {
    print(error) // prints: Error Domain=NSCocoaErrorDomain Code=3840 "No value for key in object around character 9." UserInfo={NSDebugDescription=No value for key in object around character 9.}
}

#2. Using a method that throws and returns an optional type

import Foundation

func convertToDictionary(from text: String) throws -> [String: String]? {
    guard let data = text.data(using: .utf8) else { return [:] }
    let anyResult: Any = try JSONSerialization.jsonObject(with: data, options: [])
    return anyResult as? [String: String]
}

Usage:

let string1 = "{\"City\":\"Paris\"}"
do {
    let dictionary = try convertToDictionary(from: string1)
    print(String(describing: dictionary)) // prints: Optional(["City": "Paris"])
} catch {
    print(error)
}

let string2 = "{\"Quantity\":100}"
do {
    let dictionary = try convertToDictionary(from: string2)
    print(String(describing: dictionary)) // prints nil
} catch {
    print(error)
}

let string3 = "{\"Object\"}"
do {
    let dictionary = try convertToDictionary(from: string3)
    print(String(describing: dictionary))
} catch {
    print(error) // prints: Error Domain=NSCocoaErrorDomain Code=3840 "No value for key in object around character 9." UserInfo={NSDebugDescription=No value for key in object around character 9.}
}

#3. Using a method that does not throw and returns a non-optional type

import Foundation

func convertToDictionary(from text: String) -> [String: String] {
    guard let data = text.data(using: .utf8) else { return [:] }
    let anyResult: Any? = try? JSONSerialization.jsonObject(with: data, options: [])
    return anyResult as? [String: String] ?? [:]
}

Usage:

let string1 = "{\"City\":\"Paris\"}"
let dictionary1 = convertToDictionary(from: string1)
print(dictionary1) // prints: ["City": "Paris"]

let string2 = "{\"Quantity\":100}"
let dictionary2 = convertToDictionary(from: string2)
print(dictionary2) // prints: [:]

let string3 = "{\"Object\"}"
let dictionary3 = convertToDictionary(from: string3)
print(dictionary3) // prints: [:]

#4. Using a method that does not throw and returns an optional type

import Foundation

func convertToDictionary(from text: String) -> [String: String]? {
    guard let data = text.data(using: .utf8) else { return nil }
    let anyResult = try? JSONSerialization.jsonObject(with: data, options: [])
    return anyResult as? [String: String]
}

Usage:

let string1 = "{\"City\":\"Paris\"}"
let dictionary1 = convertToDictionary(from: string1)
print(String(describing: dictionary1)) // prints: Optional(["City": "Paris"])

let string2 = "{\"Quantity\":100}"
let dictionary2 = convertToDictionary(from: string2)
print(String(describing: dictionary2)) // prints: nil

let string3 = "{\"Object\"}"
let dictionary3 = convertToDictionary(from: string3)
print(String(describing: dictionary3)) // prints: nil

WORKING Method { if there is no problem other than configuration }

By Default Appache is not restricting access from ipv4. (common external ip)

What may restrict is the configurations in 'httpd.conf' (or 'apache2.conf' depending on your apache configuration)

Solution:

Replace all:

<Directory />
     AllowOverride none
    Require all denied

</Directory>

with

<Directory />
     AllowOverride none
#    Require all denied

</Directory>

hence removing out all restriction given to Apache

Replace Require local with Require all granted at C:/wamp/www/ directory

<Directory "c:/wamp/www/">
    Options Indexes FollowSymLinks
    AllowOverride all
    Require all granted
#   Require local
</Directory>

The exact answer depends on the context. In general, these characters must not be present (HTML 5.2 §3.2.4.2.5):

Text nodes and attribute values must consist of Unicode characters, must not contain U+0000 characters, must not contain permanently undefined Unicode characters (noncharacters), and must not contain control characters other than space characters. This specification includes extra constraints on the exact value of Text nodes and attribute values depending on their precise context.

For elements in HTML, the constraints of the Text content model also depends on the kind of element. For instance, an "<" inside a textarea element does not need to be escaped in HTML because textarea is an escapable raw text element.

These restrictions are scattered across the specification. E.g., attribute values (§8.1.2.3) must not contain an ambiguous ampersand and be either (i) empty, (ii) within single quotes (and thus must not contain U+0027 APOSTROPHE character '), (iii) within double quotes (must not contain U+0022 QUOTATION MARK character "), or (iv) unquoted — with the following restrictions:

... must not contain any literal space characters, any U+0022 QUOTATION MARK characters ("), U+0027 APOSTROPHE characters ('), U+003D EQUALS SIGN characters (=), U+003C LESS-THAN SIGN characters (<), U+003E GREATER-THAN SIGN characters (>), or U+0060 GRAVE ACCENT characters (`), and must not be the empty string.

If your file my.cnf (usually in the etc folder) is correctly configured with

socket=/var/lib/mysql/mysql.sock

you can check if mysql is running with the following command:

mysqladmin -u root -p status

try changing your permission to mysql folder. If you are working locally, you can try:

sudo chmod -R 777 /var/lib/mysql/

that solved it for me

The tikz package seems to have what you want.

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{snakes}

\begin{document}

  \begin{tikzpicture}[snake=zigzag, line before snake = 5mm, line after snake = 5mm]

    \draw (7,0) node[below=3pt] {$ n $} node[above=3pt] {$ 10n $};
  \end{tikzpicture}

\end{document}

I'm not too expert with tikz, but this does give a good timeline, which looks like:

Basically, since Python 3.x you need to use print with parenthesis.

Python 2.x: print "Lord of the Rings"

Python 3.x: print("Lord of the Rings")

Explaination

print was a statement in 2.x, but it's a function in 3.x. Now, there are a number of good reasons for this.

1. With function format of Python 3.x, more flexibility comes when printing multiple items with comman separated.
2. You can't use argument splatting with a statement. In 3.x if you have a list of items that you want to print with a separator, you can do this:

>>> items = ['foo', 'bar', 'baz']
>>> print(*items, sep='+') 
foo+bar+baz

3. You can't override a statement. If you want to change the behavior of print, you can do that when it's a function but not when it's a statement.

If the answers already posted didn't help, one can try with $location.search().myParam; with URLs http://example.domain#?myParam=paramValue

You can't set the value of a file input in the markup, like you did with value="123".

This example shows that it really works: http://jsfiddle.net/marcosfromero/7bUba/

Use a JSON library to parse the string and retrieve the value.

The following very basic example uses the built-in JSON parser from Android.

String jsonString = "{ \"name\" : \"John\", \"age\" : \"20\", \"address\" : \"some address\" }";
JSONObject jsonObject = new JSONObject(jsonString);
int age = jsonObject.getInt("age");

More advanced JSON libraries, such as jackson, google-gson, json-io or genson, allow you to convert JSON objects to Java objects directly.

If you plan to create a PHP package you most likely want to put in on Packagist to make it available for other with composer. Composer has the as naming-convention to use vendorname/package-name-is-lowercase-with-hyphens.

If you plan to create a JS package you probably want to use npm. One of their naming conventions is to not permit upper case letters in the middle of your package name.

Therefore, I would recommend for PHP and JS packages to use lowercase-with-hyphens and name your packages in composer or npm identically to your package on GitHub.

HttpServerUtility.UrlEncode will use HttpUtility.UrlEncode internally. There is no specific difference. The reason for existence of Server.UrlEncode is compatibility with classic ASP.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text.RegularExpressions;

namespace SamplePrograme
{
    public class Program
    {
        public enum Suit : int
        {
            Spades = 0,
            Hearts = 1,
            Clubs = 2,
            Diamonds = 3
        }

        public static void Main(string[] args)
        {
            //from string
            Console.WriteLine((Suit) Enum.Parse(typeof(Suit), "Clubs"));

            //from int
            Console.WriteLine((Suit)1);

            //From number you can also
            Console.WriteLine((Suit)Enum.ToObject(typeof(Suit) ,1));
        }
    }
}

You could use

jQuery('#gregsButton').click(function() { 
    var mb = jQuery('#myDiv').text(); 
    alert("Value of div is: " + mb); 
});

Looks like there may be a conflict with using the $. Remember that the variable 'mb' will not be accessible outside of the event handler. Also, the text() function returns a string, no need to get mb.value.

If you want to record video from within a web browser, I think your only option is Flash. We are looking to do the same thing. We are also primarily a .NET house and I don't see a way to use .NET to capture the webcam _from_within_the_browser_. All of the other solutions mentioned here would probably work great if you are happy to settle for a desktop app

Try this, maybe can help, it do what you want:

ListArray

var listArray = new ListArray();_x000D_
let element = {name: 'Edy', age: 27, country: "Brazil"};_x000D_
let element2 = {name: 'Marcus', age: 27, country: "Brazil"};_x000D_
listArray.push(element);_x000D_
listArray.push(element2);_x000D_
_x000D_
console.log(listArray.array)

<script src="https://marcusvi200.github.io/list-array/script/ListArray.js"></script>

You can use SHOW OPEN TABLES to show each table's lock status. More details on the command's doc page are here.

i think the assets folder is public, you can access it directly on the browser

http://localhost:4020/assets/

unlike other privates folders, drop your json file in the assets folder

Heads up,

JAVASCRIPT

<script>
   function readMtlAtClient(){

       mtlFileContent = '';

       var mtlFile = document.getElementById('mtlFileInput').files[0];
       var readerMTL = new FileReader();

       // Closure to capture the file information.
       readerMTL.onload = (function(reader) {
           return function() {
               mtlFileContent = reader.result;
               mtlFileContent = mtlFileContent.replace('data:;base64,', '');
               mtlFileContent = window.atob(mtlFileContent);

           };
       })(readerMTL);

       readerMTL.readAsDataURL(mtlFile);
   }
</script>

HTML

    <input class="FullWidth" type="file" name="mtlFileInput" value="" id="mtlFileInput" 
onchange="readMtlAtClient()" accept=".mtl"/>

Then mtlFileContent has your text as a decoded string !

No need for third party tools when Android Studio can generate icons for us.

• File -> New -> Image Asset

• Then choose Launcher Icons as the Asset Type:

• Choose a High-res image for the Image file:

• Next -> Finish to generate icons

Finally update android:icon name field in AndroidManifest.xml if required.

Look for an installation subdirectory, likely named eclipse. Under that subdirectory, if you see files like eclipse.ini, icon.xpm and subdirectories like plugins and dropins, remove the subdirectory parent (the one named eclipse).

That will remove your installation except for anything you've set up yourself (like workspaces, projects, etc.).

Hope this helps.

ES6 gives you now the opportunity to use class & extends keywords :

Then , your code will be :

You have a base class:

class Monster{
       constructor(){
             this.health = 100;
        }
       growl() {
           console.log("Grr!");
       }

}

That You want to extend and create another class with:

class Monkey extends Monster {
        constructor(){
            super(); //don't forget "super"
            this.bananaCount = 5;
        }


        eatBanana() {
           this.bananaCount--;
           this.health++; //Accessing variable from parent class monster
           this.growl(); //Accessing function from parent class monster
        }

}

You can't. A DateTime in .NET always have a time, defaulting to 00:00:00:000. The Date property of a DateTime is also a DateTime (!), thus having a time defaulting to 00:00:00:000 as well.

This is a shortage in the .NET Framework, and it could be argued that DateTime in .NET violates the Single Responsibility Principle.

You can use display: inline-block.

Just note the difference between the range operators:

3..10  # includes 10
3...10 # doesn't include 10

use os.walk to recursively list your files

import os
root = "/home"
pattern = "145992"
alist_filter = ['jpg','bmp','png','gif'] 
path=os.path.join(root,"mydir_to_scan")
for r,d,f in os.walk(path):
    for file in f:
        if file[-3:] in alist_filter and pattern in file:
            print os.path.join(root,file)

Open xcode and in the top menu go to xcode > Preferences > Downloads and you will be given the option to download old sdks to use with xcode. You can also download command line tools and Device Debugging Support.

I suggest that you start from a question in StackOverflow that discusses the advantages of stateless programming. This is more in the context of functional programming, but what you will read also applies in other programming paradigms.

Stateless programming is related to the mathematical notion of a function, which when called with the same arguments, always return the same results. This is a key concept of the functional programming paradigm and I expect that you will be able to find many relevant articles in that area.

Another area that you could research in order to gain more understanding is RESTful web services. These are by design "stateless", in contrast to other web technologies that try to somehow keep state. (In fact what you say that ASP.NET is stateless isn't correct - ASP.NET tries hard to keep state using ViewState and are definitely to be characterized as stateful. ASP.NET MVC on the other hand is a stateless technology). There are many places that discuss "statelessness" of RESTful web services (like this blog spot), but you could again start from an SO question.

As of spring boot 2 the server.contextPath property is deprecated. Instead you should use server.servlet.contextPath.

So in your application.properties file add:

server.servlet.contextPath=/myWebApp

For more details see: https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-2.0-Migration-Guide#servlet-specific-server-properties

you may try like this using jquery

 var arr = [1,2,2,3,4,5,5,5,6,7,7,8,9,10,10];
    var uniqueVals = [];
    $.each(arr, function(i, el){
        if($.inArray(el, uniqueVals) === -1) uniqueVals.push(el);
    });

Well, from my understanding, simply for matching this format in a given string, I prefer this regular expression:

pattern='[0-9|/]+'

to match the format in a more strict way, the following works:

pattern='(?:[0-9]{2}/){2}[0-9]{2}'

Personally, I cannot agree with unutbu's answer since sometimes we use regular expression for "finding" and "extract", not only "validating".

If you want to be able to toggle the display of whitespaces on and off, you can install the HighlightWhitespaces plugin

Here's a small script implementing this feature (inspired by the Shea Frederick blog article that Kyle mentions):

• Pointer Events Polyfill.

Don't forget SET SCHEMA 'myschema' which you could use in a separate Statement

SET SCHEMA 'value' is an alias for SET search_path TO value. Only one schema can be specified using this syntax.

And since 9.4 and possibly earlier versions on the JDBC driver, there is support for the setSchema(String schemaName) method.

Another way to make it in Python 3:

numbers = [*map(int, numbers)]

In my case, my array was multidimensional, potentially with arrays as values. So I created this recursive function to blow apart the array completely:

function array2csv($array, &$title, &$data) {
    foreach($array as $key => $value) {      
        if(is_array($value)) {
            $title .= $key . ",";
            $data .= "" . ",";
            array2csv($value, $title, $data);
        } else {
            $title .= $key . ",";
            $data .= '"' . $value . '",';
        }
    }
}

Since the various levels of my array didn't lend themselves well to a the flat CSV format, I created a blank column with the sub-array's key to serve as a descriptive "intro" to the next level of data. Sample output:

agentid     fname           lname      empid    totals  sales   leads   dish    dishnet top200_plus top120  latino  base_packages
G-adriana   ADRIANA EUGENIA PALOMO PAIZ 886                0    19              0         0         0         0      0

You could easily remove that "intro" (descriptive) column, but in my case I had repeating column headers, i.e. inbound_leads, in each sub-array, so that gave me a break/title preceding the next section. Remove:

$title .= $key . ",";
$data .= "" . ",";

after the is_array() to compact the code further and remove the extra column.

Since I wanted both a title row and data row, I pass two variables into the function and upon completion of the call to the function, terminate both with PHP_EOL:

$title .= PHP_EOL;
$data .= PHP_EOL;

Yes, I know I leave an extra comma, but for the sake of brevity, I didn't handle it here.

An example of a lambda in Ruby is as follows:

hello = lambda do
    puts('Hello')
    puts('I am inside a proc')
end

hello.call

Will genereate the following output:

Hello
I am inside a proc

<?php
spl_autoload_register(function ($classname){
   // for security purpose
   //your class name should match the name of your class "file.php"
   $classname = str_replace("..", "", $classname);
   require_once __DIR__.DIRECTORY_SEPARATOR.("classes/$classname.class.php");
});
try {
  $new = new Class1();
} catch (Exception $e) {
   echo "error = ". $e->getMessage();
}
?>

You should be able to use

IIF(Fields!ExitReason.Value = 7, 1, 0)

http://msdn.microsoft.com/en-us/library/ms157328.aspx

To do that you should do:

a =  [5, 7, 11, 4, 5]
for i in range(len(a)-1):
    print [a[i], a[i+1]]

This will give just the names of the stored procedures.

select specific_name
from information_schema.routines
where routine_type = 'PROCEDURE';

You can just create a folder ProgramFiles at local D or local C to install those apps that can be install to a folder name which has a SPACES / Characters on it.

Another method that may work for you (it's how I do it) is registering a class.

Assume you create a custom tableView like the following:

class UICustomTableViewCell: UITableViewCell {...}

You can then register this cell in whatever UITableViewController you will be displaying it in with "registerClass":

override func viewDidLoad() {
    super.viewDidLoad()
    tableView.registerClass(UICustomTableViewCell.self, forCellReuseIdentifier: "UICustomTableViewCellIdentifier")
}

And you can call it as you would expect in the cell for row method:

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("UICustomTableViewCellIdentifier", forIndexPath: indexPath) as! UICustomTableViewCell
    return cell
}

I realise this thread is quite old now, but I was having the same problem. This was my very basic solution using the MySQL Workbench, but it worked fine...

1. get a new sql editor and execute SHOW TABLES to get a list of your tables
2. select all of the rows, and choose copy to clipboard (unquoted) from the context menu
3. paste the list of names into another editor tab
4. write your query, ie ALTER TABLE x DROP a;
5. do some copying and pasting, so you end up with separate query for each table
6. Toggle whether the workbench should stop when an error occurs
7. Hit execute and look through the output log

any tables which had the table now haven't any tables which didn't will have shown an error in the logs

then you can find/replace 'drop a' change it to 'ADD COLUMN b INT NULL' etc and run the whole thing again....

a bit clunky, but at last you get the end result and you can control/monitor the whole process and remember to save you sql scripts in case you need them again.

I'm completely revising my original answer because of points raised in the other questions and comments. Here is the new benchmark script:

import time
import numpy as np


def fancy_index_relu(m):
    m[m < 0] = 0


relus = {
    "max": lambda x: np.maximum(x, 0),
    "in-place max": lambda x: np.maximum(x, 0, x),
    "mul": lambda x: x * (x > 0),
    "abs": lambda x: (abs(x) + x) / 2,
    "fancy index": fancy_index_relu,
}

for name, relu in relus.items():
    n_iter = 20
    x = np.random.random((n_iter, 5000, 5000)) - 0.5

    t1 = time.time()
    for i in range(n_iter):
        relu(x[i])
    t2 = time.time()

    print("{:>12s}  {:3.0f} ms".format(name, (t2 - t1) / n_iter * 1000))

It takes care to use a different ndarray for each implementation and iteration. Here are the results:

         max  126 ms
in-place max  107 ms
         mul  136 ms
         abs   86 ms
 fancy index  132 ms

The best approach for you to communicate between the two controllers is to use events.

See the scope documentation

In this check out $on, $broadcast and $emit.

Defining a single type for all is not always possible. Even if when you can, the implementation is rarely easy. I prefer to use out parameters. The only caveat is that you need to know all the return types in advanced:

public void GetAnything(out Hello h, out Computer c, out Radio r)
{
     /// I suggest to:
     h = null;
     c = null;
     r = null; 
     // first, 

     // Then do whatever you have to do:
     Hello hello = new Hello();
     Computer computer = new Computer();
     Radio radio = new Radio();
}

The return type can be a void, or something else, like bool an int or a predefined enum which can help you check for exceptions or different cases wherever the method is used.

First, you need to create your branch locally

git checkout -b your_branch

After that, you can work locally in your branch, when you are ready to share the branch, push it. The next command push the branch to the remote repository origin and tracks it

git push -u origin your_branch

Your Teammates/colleagues can push to your branch by doing commits and then push explicitly

... work ...
git commit
... work ...
git commit
git push origin HEAD:refs/heads/your_branch 

This cannot be done with pure HTML/JS, you will need CSS

CSS:

button {
     width: 100%;
     height: 100%;
}

Substitute 100% with required size

This can be done in many ways

This should do it:

1. Ctrl+A - select all.
2. Ctrl+Shift+L - split selection into lines.
3. Then move all cursors with left/right, select with Shift+left/right. Move all cursors to start of line with Home.

There's already a lot about how to not leak, but if you need a tool to help you track leaks take a look at:

• BoundsChecker under VS
• MMGR C/C++ lib from FluidStudio http://www.paulnettle.com/pub/FluidStudios/MemoryManagers/Fluid_Studios_Memory_Manager.zip (its overrides the allocation methods and creates a report of the allocations, leaks, etc)

Lets try the example

     ArrayList<String> firstArrayList = new ArrayList<>();
            firstArrayList.add("One");
            firstArrayList.add("Two");
            firstArrayList.add("Three");
            firstArrayList.add("Four");
            firstArrayList.add("Five");
            firstArrayList.add("Six");
            //copy array list content into another array list
             ArrayList<String> secondArrayList=new ArrayList<>();
            secondArrayList.addAll(firstArrayList);
            //print all the content of array list
            Iterator itr = secondArrayList.iterator();
            while (itr.hasNext()) {
                System.out.println(itr.next());
            }

In print output as below

One
Two
Three
Four
Five
Six

We can also do by using clone() method for which is used to create exact copy

for that try you can try as like

 **ArrayList<String>secondArrayList = (ArrayList<String>) firstArrayList.clone();**
    And then print by using iterator
      **Iterator itr = secondArrayList.iterator();
                while (itr.hasNext()) {
                    System.out.println(itr.next());
                }**

Dir

Use the dir command. Type in dir /? for help and options.

dir /a:d /b

Redirect

Then use a redirect to save the list to a file.

> list.txt

Together

dir /a:d /b > list.txt

This will output just the names of the directories. if you want the full path of the directories use this below.

Full Path

for /f "delims=" %%D in ('dir /a:d /b') do echo %%~fD

Alternative

other method just using the for command. See for /? for help and options. This can output just the name %%~nxD or the full path %%~fD

for /d %%D in (*) do echo %%~fD

Notes

To use these commands directly on the command line, change the double percent signs to single percent signs. %% to %

To redirect the for methods, just add the redirect after the echo statements. Use the double arrow >> redirect here to append to the file, else only the last statement will be written to the file due to overwriting all the others.

... echo %%~fD>> list.txt

I found out that my back-up project worked well if I precompile without bundle update. Maybe something went wrong with gem updated but I don't know which gem has an error.

Full credit to bchr02 for this answer. However, I had to modify it a bit to catch the scenario for lines that have */ (end of comment) followed by an empty line. The regex was matching the non empty line with */.

New: (^(\r\n|\n|\r)$)|(^(\r\n|\n|\r))|^\s*$/gm

All I did is add ^ as second character to signify the start of line.

Boolean is the object wrapper class for the primitive boolean. This class, as any class, can indeed be null. For performance and memory reasons it is always best to use the primitive.

The wrapper classes in the Java API serve two primary purposes:

1. To provide a mechanism to “wrap” primitive values in an object so that the primitives can be included in activities reserved for objects, like as being added to Collections, or returned from a method with an object return value.
2. To provide an assortment of utility functions for primitives. Most of these functions are related to various conversions: converting primitives to and from String objects, and converting primitives and String objects to and from different bases (or radix), such as binary, octal, and hexadecimal.

This method applies the standard .gitignore behavior, and does not require manually specifying the files that need to be ignored.

Can't use --exclude-from=.gitignore anymore :/ - Here's the updated method:

General advice: start with a clean repo - everything committed, nothing pending in working directory or index, and make a backup!

#commit up-to-date .gitignore (if not already existing)
#this command must be run on each branch
git add .gitignore
git commit -m "Create .gitignore"

#apply standard git ignore behavior only to current index, not working directory (--cached)
#if this command returns nothing, ensure /.git/info/exclude AND/OR .gitignore exist
#this command must be run on each branch
git ls-files -z --ignored --exclude-standard | xargs -0 git rm --cached

#optionally add anything to the index that was previously ignored but now shouldn't be:
git add *

#commit again
#optionally use the --amend flag to merge this commit with the previous one instead of creating 2 commits.

git commit -m "re-applied modified .gitignore"

#other devs who pull after this commit is pushed will see the  newly-.gitignored files DELETED

If you also need to purge the newly-ignored files from the branch's commit history or if you don't want the newly-ignored files to be deleted from future pulls, see this answer.

You could use an onclick event handler in order to get the input value for the text field. Make sure you give the field an unique id attribute so you can refer to it safely through document.getElementById():

If you want to dynamically add elements, you should have a container where to place them. For instance, a <div id="container">. Create new elements by means of document.createElement(), and use appendChild() to append each of them to the container. You might be interested in outputting a meaningful name attribute (e.g. name="member"+i for each of the dynamically generated <input>s if they are to be submitted in a form.

Notice you could also create <br/> elements with document.createElement('br'). If you want to just output some text, you can use document.createTextNode() instead.

Also, if you want to clear the container every time it is about to be populated, you could use hasChildNodes() and removeChild() together.

<html>
<head>
    <script type='text/javascript'>
        function addFields(){
            // Number of inputs to create
            var number = document.getElementById("member").value;
            // Container <div> where dynamic content will be placed
            var container = document.getElementById("container");
            // Clear previous contents of the container
            while (container.hasChildNodes()) {
                container.removeChild(container.lastChild);
            }
            for (i=0;i<number;i++){
                // Append a node with a random text
                container.appendChild(document.createTextNode("Member " + (i+1)));
                // Create an <input> element, set its type and name attributes
                var input = document.createElement("input");
                input.type = "text";
                input.name = "member" + i;
                container.appendChild(input);
                // Append a line break 
                container.appendChild(document.createElement("br"));
            }
        }
    </script>
</head>
<body>
    <input type="text" id="member" name="member" value="">Number of members: (max. 10)<br />
    <a href="#" id="filldetails" onclick="addFields()">Fill Details</a>
    <div id="container"/>
</body>

TL;DR: git branch --set-upstream-to origin/solaris

The answer to the question you asked—which I'll rephrase a bit as "do I have to set an upstream"—is: no, you don't have to set an upstream at all.

If you do not have upstream for the current branch, however, Git changes its behavior on git push, and on other commands as well.

The complete push story here is long and boring and goes back in history to before Git version 1.5. To shorten it a whole lot, git push was implemented poorly.¹ As of Git version 2.0, Git now has a configuration knob spelled push.default which now defaults to simple. For several versions of Git before and after 2.0, every time you ran git push, Git would spew lots of noise trying to convince you to set push.default just to get git push to shut up.

You do not mention which version of Git you are running, nor whether you have configured push.default, so we must guess. My guess is that you are using Git version 2-point-something, and that you have set push.default to simple to get it to shut up. Precisely which version of Git you have, and what if anything you have push.default set to, does matter, due to that long and boring history, but in the end, the fact that you're getting yet another complaint from Git indicates that your Git is configured to avoid one of the mistakes from the past.

What is an upstream?

An upstream is simply another branch name, usually a remote-tracking branch, associated with a (regular, local) branch.

Every branch has the option of having one (1) upstream set. That is, every branch either has an upstream, or does not have an upstream. No branch can have more than one upstream.

The upstream should, but does not have to be, a valid branch (whether remote-tracking like origin/B or local like master). That is, if the current branch B has upstream U, git rev-parse U should work. If it does not work—if it complains that U does not exist—then most of Git acts as though the upstream is not set at all. A few commands, like git branch -vv, will show the upstream setting but mark it as "gone".

What good is an upstream?

If your push.default is set to simple or upstream, the upstream setting will make git push, used with no additional arguments, just work.

That's it—that's all it does for git push. But that's fairly significant, since git push is one of the places where a simple typo causes major headaches.

If your push.default is set to nothing, matching, or current, setting an upstream does nothing at all for git push.

(All of this assumes your Git version is at least 2.0.)

The upstream affects git fetch

If you run git fetch with no additional arguments, Git figures out which remote to fetch from by consulting the current branch's upstream. If the upstream is a remote-tracking branch, Git fetches from that remote. (If the upstream is not set or is a local branch, Git tries fetching origin.)

The upstream affects git merge and git rebase too

If you run git merge or git rebase with no additional arguments, Git uses the current branch's upstream. So it shortens the use of these two commands.

The upstream affects git pull

You should never² use git pull anyway, but if you do, git pull uses the upstream setting to figure out which remote to fetch from, and then which branch to merge or rebase with. That is, git pull does the same thing as git fetch—because it actually runs git fetch—and then does the same thing as git merge or git rebase, because it actually runs git merge or git rebase.

(You should usually just do these two steps manually, at least until you know Git well enough that when either step fails, which they will eventually, you recognize what went wrong and know what to do about it.)

The upstream affects git status

This may actually be the most important. Once you have an upstream set, git status can report the difference between your current branch and its upstream, in terms of commits.

If, as is the normal case, you are on branch B with its upstream set to origin/B, and you run git status, you will immediately see whether you have commits you can push, and/or commits you can merge or rebase onto.

This is because git status runs:

• git rev-list --count @{u}..HEAD: how many commits do you have on B that are not on origin/B?
• git rev-list --count HEAD..@{u}: how many commits do you have on origin/B that are not on B?

Setting an upstream gives you all of these things.

How come master already has an upstream set?

When you first clone from some remote, using:

$ git clone git://some.host/path/to/repo.git

or similar, the last step Git does is, essentially, git checkout master. This checks out your local branch master—only you don't have a local branch master.

On the other hand, you do have a remote-tracking branch named origin/master, because you just cloned it.

Git guesses that you must have meant: "make me a new local master that points to the same commit as remote-tracking origin/master, and, while you're at it, set the upstream for master to origin/master."

This happens for every branch you git checkout that you do not already have. Git creates the branch and makes it "track" (have as an upstream) the corresponding remote-tracking branch.

But this doesn't work for new branches, i.e., branches with no remote-tracking branch yet.

If you create a new branch:

$ git checkout -b solaris

there is, as yet, no origin/solaris. Your local solaris cannot track remote-tracking branch origin/solaris because it does not exist.

When you first push the new branch:

$ git push origin solaris

that creates solaris on origin, and hence also creates origin/solaris in your own Git repository. But it's too late: you already have a local solaris that has no upstream.³

Shouldn't Git just set that, now, as the upstream automatically?

Probably. See "implemented poorly" and footnote 1. It's hard to change now: There are millions⁴ of scripts that use Git and some may well depend on its current behavior. Changing the behavior requires a new major release, nag-ware to force you to set some configuration field, and so on. In short, Git is a victim of its own success: whatever mistakes it has in it, today, can only be fixed if the change is either mostly invisible, clearly-much-better, or done slowly over time.

The fact is, it doesn't today, unless you use --set-upstream or -u during the git push. That's what the message is telling you.

You don't have to do it like that. Well, as we noted above, you don't have to do it at all, but let's say you want an upstream. You have already created branch solaris on origin, through an earlier push, and as your git branch output shows, you already have origin/solaris in your local repository.

You just don't have it set as the upstream for solaris.

To set it now, rather than during the first push, use git branch --set-upstream-to. The --set-upstream-to sub-command takes the name of any existing branch, such as origin/solaris, and sets the current branch's upstream to that other branch.

That's it—that's all it does—but it has all those implications noted above. It means you can just run git fetch, then look around, then run git merge or git rebase as appropriate, then make new commits and run git push, without a bunch of additional fussing-around.

¹To be fair, it was not clear back then that the initial implementation was error-prone. That only became clear when every new user made the same mistakes every time. It's now "less poor", which is not to say "great".

²"Never" is a bit strong, but I find that Git newbies understand things a lot better when I separate out the steps, especially when I can show them what git fetch actually did, and they can then see what git merge or git rebase will do next.

³If you run your first git push as git push -u origin solaris—i.e., if you add the -u flag—Git will set origin/solaris as the upstream for your current branch if (and only if) the push succeeds. So you should supply -u on the first push. In fact, you can supply it on any later push, and it will set or change the upstream at that point. But I think git branch --set-upstream-to is easier, if you forgot.

⁴Measured by the Austin Powers / Dr Evil method of simply saying "one MILLLL-YUN", anyway.

xs:boolean is predefined with regard to what kind of input it accepts. If you need something different, you have to define your own enumeration:

 <xs:simpleType name="my:boolean">
    <xs:restriction base="xs:string">
      <xs:enumeration value="True"/>
      <xs:enumeration value="False"/>
    </xs:restriction>
  </xs:simpleType>

This should be what you need.

Here's a sample method that adds two extra columns programmatically to the grid view:

    private void AddColumnsProgrammatically()
    {
        // I created these columns at function scope but if you want to access 
        // easily from other parts of your class, just move them to class scope.
        // E.g. Declare them outside of the function...
        var col3 = new DataGridViewTextBoxColumn();
        var col4 = new DataGridViewCheckBoxColumn();

        col3.HeaderText = "Column3";
        col3.Name = "Column3";

        col4.HeaderText = "Column4";
        col4.Name = "Column4";

        dataGridView1.Columns.AddRange(new DataGridViewColumn[] {col3,col4});
    }

A great way to figure out how to do this kind of process is to create a form, add a grid view control and add some columns. (This process will actually work for ANY kind of form control. All instantiation and initialization happens in the Designer.) Then examine the form's Designer.cs file to see how the construction takes place. (Visual Studio does everything programmatically but hides it in the Form Designer.)

For this example I created two columns for the view named Column1 and Column2 and then searched Form1.Designer.cs for Column1 to see everywhere it was referenced. The following information is what I gleaned and, copied and modified to create two more columns dynamically:

// Note that this info scattered throughout the designer but can easily collected.

        this.dataGridView1.Columns.AddRange(new System.Windows.Forms.DataGridViewColumn[] {
        this.Column1,
        this.Column2});

        this.Column1.HeaderText = "Column1";
        this.Column1.Name = "Column1";

        this.Column2.HeaderText = "Column2";
        this.Column2.Name = "Column2";

Simple explanation about SOAP and REST

SOAP - "Simple Object Access Protocol"

SOAP is a method of transferring messages, or small amounts of information, over the Internet. SOAP messages are formatted in XML and are typically sent using HTTP (hypertext transfer protocol).

Rest - Representational state transfer

Rest is a simple way of sending and receiving data between client and server and it doesn't have very many standards defined. You can send and receive data as JSON, XML or even plain text. It's light weighted compared to SOAP.

The answers above were most useful and I learned a lot. However, for my needs the succinct answer is:

hg revert --all --rev ${1}

hg commit -m "Restoring branch ${1} as default"

where ${1} is the number of the revision or the name of the branch. These two lines are actually part of a bash script, but they work fine on their own if you want to do it manually.

This is useful if you need to add a hot fix to a release branch, but need to build from default (until we get our CI tools right and able to build from branches and later do away with release branches as well).

You can use SimpleDateFormat

SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
Date d = sdf.parse("21/12/2012");

But I don't know whether it should be considered more right than to use Calendar ...

If it's a CLOB why can't we to_char the column and then search normally ?

Create a table

CREATE TABLE MY_TABLE(Id integer PRIMARY KEY, Name varchar2(20), message clob);

Create few records in this table

INSERT INTO MY_TABLE VALUES(1,'Tom','Hi This is Row one');
INSERT INTO MY_TABLE VALUES(2,'Lucy', 'Hi This is Row two');
INSERT INTO MY_TABLE VALUES(3,'Frank', 'Hi This is Row three');
INSERT INTO MY_TABLE VALUES(4,'Jane', 'Hi This is Row four');
INSERT INTO MY_TABLE VALUES(5,'Robert', 'Hi This is Row five');
COMMIT;

Search in the clob column

SELECT * FROM MY_TABLE where to_char(message) like '%e%';

Results

ID   NAME    MESSAGE   
===============================  
1    Tom     Hi This is Row one         
3    Frank   Hi This is Row three
5    Robert  Hi This is Row five

Use break.

Unrelated to your question, I see in your code the line:

Violated = !(name.firstname == null) ? false : true;

In this line, you take a boolean value (name.firstname == null). Then, you apply the ! operator to it. Then, if the value is true, you set Violated to false; otherwise to true. So basically, Violated is set to the same value as the original expression (name.firstname == null). Why not use that, as in:

Violated = (name.firstname == null);

The answer to this may depend largely on the UUID version.

Many UUID generators use a version 4 random number. However, many of these use Pseudo a Random Number Generator to generate them.

If a poorly seeded PRNG with a small period is used to generate the UUID I would say it's not very safe at all. Some random number generators also have poor variance. i.e. favouring certain numbers more often than others. This isn't going to work well.

Therefore, it's only as safe as the algorithms used to generate it.

On the flip side, if you know the answer to these questions then I think a version 4 uuid should be very safe to use. In fact I'm using it to identify blocks on a network block file system and so far have not had a clash.

In my case, the PRNG I'm using is a mersenne twister and I'm being careful with the way it's seeded which is from multiple sources including /dev/urandom. Mersenne twister has a period of 2^19937 - 1. It's going to be a very very long time before I see a repeat uuid.

So pick a good library or generate it yourself and make sure you use a decent PRNG algorithm.

There are two ways to set this up. If you have an SID, use this (older) format:

jdbc:oracle:thin:@[HOST][:PORT]:SID

If you have an Oracle service name, use this (newer) format:

jdbc:oracle:thin:@//[HOST][:PORT]/SERVICE

The call to getConnection() is correct.

Also, as duffymo said, make sure the actual driver code is present by including ojdbc6.jar in the classpath, where the number corresponds to the Java version you're using.

 //book[title/@lang = 'it']

I tried it using vtd-xml, both expressions spit out the same result... what xpath processing engine did you use? I guess it has conformance issue Below is the code

import com.ximpleware.*;
public class test1 {
  public static void main(String[] s) throws Exception{
      VTDGen vg = new VTDGen();
      if (vg.parseFile("c:/books.xml", true)){
          VTDNav vn = vg.getNav();
          AutoPilot ap = new AutoPilot(vn);
          ap.selectXPath("//book[title[@lang='it']]");
                  //ap.selectXPath("//book[title/@lang='it']");

          int i;

          }

<div> looks nice, but a bit complicated in setting all these display: block, float: left... Maybe because the general idea behind <div> is a block of a paragraph size or more.

I have found the following nice way for spacing:

<button>Button 1></button>
<button style="margin-left: 4em">Button 2</button>

Another way to do it would include using filter like this:

countries = list(filter(lambda x: str(x) != 'nan', countries))

You want:

foreach (int number in numbers) //   <--- go back to here --------+
{                               //                                |
    if (number < 0)             //                                |
    {                           //                                |
        continue;   // Skip the remainder of this iteration. -----+
    }

    // do work
}

Here's more about the continue keyword.

Update: In response to Brian's follow-up question in the comments:

Could you further clarify what I would do if I had nested for loops, and wanted to skip the iteration of one of the extended ones?

for (int[] numbers in numberarrays) {
  for (int number in numbers) { // What to do if I want to
                                // jump the (numbers/numberarrays)?
  }
}

A continue always applies to the nearest enclosing scope, so you couldn't use it to break out of the outermost loop. If a condition like that arises, you'd need to do something more complicated depending on exactly what you want, like break from the inner loop, then continue on the outer loop. See here for the documentation on the break keyword. The break C# keyword is similar to the Perl last keyword.

Also, consider taking Dustin's suggestion to just filter out values you don't want to process beforehand:

foreach (var basket in baskets.Where(b => b.IsOpen())) {
  foreach (var fruit in basket.Where(f => f.IsTasty())) {
    cuteAnimal.Eat(fruit); // Om nom nom. You don't need to break/continue
                           // since all the fruits that reach this point are
                           // in available baskets and tasty.
  }
}

echo "echo "we are now going to work with ${ser}" " >> $servfile

Escape all " within quotes with \. Do this with variables like \$servicetest too:

echo "echo \"we are now going to work with \${ser}\" " >> $servfile    
echo "read -p \"Please enter a service: \" ser " >> $servfile
echo "if [ \$servicetest > /dev/null ];then " >> $servfile

Using plaintext may not be the best choice, if the password is ever used as something else.

I support the accepted answer, but it didn't work for me - for a very specific reason: I wanted to use either kwallet or gnome-keyring password stores. I tried changing the settings, all over the four files:

/etc/subversion/config
/etc/subversion/servers
~/.subversion/config
~/.subversion/servers

Even after it all was set the same, with password-stores and KWallet name (default might be wrong, right?) it didn't work and kept asking for password forever. The files in ~/.subversion had permissions 600.

Well, at that point, you may try to check one simple thing:

which svn

If you get:

/usr/bin/local/svn

then you may suspect with great likelihood that this client was built from source, locally, by your administrator (which may be yourself, as in my case).

Subversion is a nasty beast to compile, very easy to accidentally build without HTTP support, or - as in my example - without support for encrypted password stores (you need either Gnome or KDE development files, and a lot of them!). But the ./configure script won't tell you that, and you just get a less functional svn command.

In that case, you may go back to the client, which came with your distribution, usually in /usr/bin/svn. The downside is - you'll probably need to re-checkout the working copies, as there is no svn downgrade command. You can consult Linus Torvalds on what to think about Subversion, anyway ;)

Something quick and dirty:

<script type='text/javascript'>
function del_tr(remtr)  
{   
    while((remtr.nodeName.toLowerCase())!='tr')
        remtr = remtr.parentNode;

    remtr.parentNode.removeChild(remtr);
}
function del_id(id)  
{   
        del_tr(document.getElementById(id));
}
</script>

if you place

<a href='' onclick='del_tr(this);return false;'>x</a>

anywhere within the row you want to delete, than its even working without any ids

Consider the case where the strings are columns and the result should be a new column:

df <- data.frame(a = letters[1:5], b = LETTERS[1:5], c = 1:5)

df$new_col <- do.call(paste, c(df[c("a", "b")], sep = ", ")) 
df
#  a b c new_col
#1 a A 1    a, A
#2 b B 2    b, B
#3 c C 3    c, C
#4 d D 4    d, D
#5 e E 5    e, E

Optionally, skip the [c("a", "b")] subsetting if all columns needs to be pasted.

# you can also try str_c from stringr package as mentioned by other users too!
do.call(str_c, c(df[c("a", "b")], sep = ", ")) 

Actually the default value of byte is 0.

I did it like this:

var listOfRows = new List<DataRow>();
foreach (var row in resultTable.Rows.Cast<DataRow>())
{
    var isEmpty = row.ItemArray.All(x => x == null || (x!= null && string.IsNullOrWhiteSpace(x.ToString())));
    if (!isEmpty)
    {
        listOfRows.Add(row);
    }
}

This problem occurs because the Web site does not have the Directory Browsing feature enabled, and the default document is not configured. To resolve this problem, use one of the following methods. To resolve this problem, I followed the steps in Method 1 as mentioned in the MS Support page and its the recommended method.

Method 1: Enable the Directory Browsing feature in IIS (Recommended)

1. Start IIS Manager. To do this, click Start, click Run, type inetmgr.exe, and then click OK.

2. In IIS Manager, expand server name, expand Web sites, and then click the website that you want to modify.

3. In the Features view, double-click Directory Browsing.

4. In the Actions pane, click Enable.

If that does not work for, you might be having different problem than just a Directory listing issue. So follow the below step,

Method 2: Add a default document

To resolve this problem, follow these steps:

• Start IIS Manager. To do this, click Start, click Run, type inetmgr.exe, and then click OK.
• In IIS Manager, expand server name, expand Web sites, and then click the website that you want to modify.
• In the Features view, double-click Default Document.
• In the Actions pane, click Enable.
• In the File Name box, type the name of the default document, and then click OK.

Method 3: Enable the Directory Browsing feature in IIS Express

_{Note This method is for the web developers who experience the issue when they use IIS Express.}

Follow these steps:

• Open a command prompt, and then go to the IIS Express folder on your computer. For example, go to the following folder in a command prompt: C:\Program Files\IIS Express

• Type the following command, and then press Enter:

  appcmd set config /section:system.webServer/directoryBrowse /enabled:true

You should try this one:

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

See http://www.dotnetperls.com/console-writeline for more details.

There are two parts of this problem

1) using a parameter that would not alter an url (using params property):

$stateProvider
    .state('login', {
        params: [
            'toStateName',
            'toParamsJson'
        ],
        templateUrl: 'partials/login/Login.html'
    })

2) passing an object as parameter: Well, there is no direct way how to do it now, as every parameter is converted to string (EDIT: since 0.2.13, this is no longer true - you can use objects directly), but you can workaround it by creating the string on your own

toParamsJson = JSON.stringify(toStateParams);

and in target controller deserialize the object again

originalParams = JSON.parse($stateParams.toParamsJson);

You can use the parse method from the URL module in the request callback.

var http = require('http');
var url = require('url');

// Configure our HTTP server to respond with Hello World to all requests.
var server = http.createServer(function (request, response) {
  var queryData = url.parse(request.url, true).query;
  response.writeHead(200, {"Content-Type": "text/plain"});

  if (queryData.name) {
    // user told us their name in the GET request, ex: http://host:8000/?name=Tom
    response.end('Hello ' + queryData.name + '\n');

  } else {
    response.end("Hello World\n");
  }
});

// Listen on port 8000, IP defaults to 127.0.0.1
server.listen(8000);

I suggest you read the HTTP module documentation to get an idea of what you get in the createServer callback. You should also take a look at sites like http://howtonode.org/ and checkout the Express framework to get started with Node faster.

Easiest way to do is :

awk 'NR==FNR{a[$1]++;next} a[$1] ' file1 file2

Files are not necessary to be sorted.

word_display = ""
for letter in word:
    if letter in known:
        word_display = "%s%s " % (word_display, letter)
    else:
        word_display = "%s_ " % word_display
return word_display

I had this error when attempting to use EF within an AutoCAD plugin. CAD plugins get the connection string from the acad.exe.config file. Add the connect string as mentioned above to the acad config file and it works.

Credit goes to Norman.Yuan from ADN.Network.

String temp = s.Replace("\r\n","").Trim();

s being the original string. (Note capitals)

You don't need to do it one at a time. Just do a test for any that are not alpha-numeric. If one is found, the validation fails.

function validateCode(){
    var TCode = document.getElementById('TCode').value;
    if( /[^a-zA-Z0-9]/.test( TCode ) ) {
       alert('Input is not alphanumeric');
       return false;
    }
    return true;     
 }

If there's at least one match of a non alpha numeric, it will return false.

I think it's perfectly explained in item 25 of Scott Meyers' Effective Modern C++. Here's an excerpt:

The part of the Standard blessing the RVO goes on to say that if the conditions for the RVO are met, but compilers choose not to perform copy elision, the object being returned must be treated as an rvalue. In effect, the Standard requires that when the RVO is permitted, either copy elision takes place or std::move is implicitly applied to local objects being returned.

Here, RVO refers to return value optimization, and if the conditions for the RVO are met means returning the local object declared inside the function that you would expect to do the RVO, which is also nicely explained in item 25 of his book by referring to the standard (here the local object includes the temporary objects created by the return statement). The biggest take away from the excerpt is either copy elision takes place or std::move is implicitly applied to local objects being returned. Scott mentions in item 25 that std::move is implicitly applied when the compiler choose not to elide the copy and the programmer should not explicitly do so.

In your case, the code is clearly a candidate for RVO as it returns the local object p and the type of p is the same as the return type, which results in copy elision. And if the compiler chooses not to elide the copy, for whatever reason, std::move would've kicked in to line 1.

Use this method and pass your array in parameter

Collections.shuffle(arrayList);

This method return void so it will not give you a new list but as we know that array is passed as a reference type in Java so it will shuffle your array and save shuffled values in it. That's why you don't need any return type.

You can now use arraylist which is shuffled.

Not sure where you add the json but if i do it like this with angular it works without the requestBody: angluar:

    const params: HttpParams = new HttpParams().set('str1','val1').set('str2', ;val2;);
    return this.http.post<any>( this.urlMatch,  params , { observe: 'response' } );

java:

@PostMapping(URL_MATCH)
public ResponseEntity<Void> match(Long str1, Long str2) {
  log.debug("found: {} and {}", str1, str2);
}

Note - This is not a solution to the original question. This is a solution to one of the subproblems discussed above.

Solution to @andr Clarification 2 -

Its really problematic when there's only one marker in the bounds and due to it the zoom level is set to a very high level (level 21). And Google does not provide any way to set the max zoom level at this point. This can also happen when there are more than 1 marker but they are all pretty close to each other. Then also the same problem will occur.

Solution - Suppose you want your Map to never go beyond 16 zoom level. Then after doing -

CameraUpdate cu = CameraUpdateFactory.newLatLngBounds(bounds, padding);
mMap.moveCamera(cu);

Check if your zoom level has crossed level 16(or whatever you want) -

float currentZoom = mMap.getCameraPosition().zoom;

And if this level is greater than 16, which it will only be if there are very less markers or all the markers are very close to each other, then simply zoom out your map at that particular position only by seting the zoom level to 16.

mMap.moveCamera(CameraUpdateFactory.zoomTo(16));

This way you'll never have the problem of "bizarre" zoom level explained very well by @andr too.

It might help the solution given in another forum, Basically is: i.e.

Cols <- paste("A", 1:5, sep="")
DF <- read.table(textConnection(""), col.names = Cols,colClasses = "character")

> str(DF)
'data.frame':   0 obs. of  5 variables:
$ A1: chr
$ A2: chr
$ A3: chr
$ A4: chr
$ A5: chr

You can change the colClasses to fit your needs.

Original link is https://stat.ethz.ch/pipermail/r-help/2008-August/169966.html

element = findElement(By.xpath("//*[@test-id='test-username']");
element = findElement(By.xpath("//input[@test-id='test-username']");

(*) - any tagname

Mark, this is already answered in your previous topic. But OK, here it is again:

Suppose ${list} points to a List<Object>, then the following

<c:forEach items="${list}" var="item">
    ${item}<br>
</c:forEach>

does basically the same as as following in "normal Java":

for (Object item : list) {
    System.out.println(item);
}

If you have a List<Map<K, V>> instead, then the following

<c:forEach items="${list}" var="map">
    <c:forEach items="${map}" var="entry">
        ${entry.key}<br>
        ${entry.value}<br>
    </c:forEach>
</c:forEach>

does basically the same as as following in "normal Java":

for (Map<K, V> map : list) {
    for (Entry<K, V> entry : map.entrySet()) {
        System.out.println(entry.getKey());
        System.out.println(entry.getValue());
    }
}

The key and value are here not special methods or so. They are actually getter methods of Map.Entry object (click at the blue Map.Entry link to see the API doc). In EL (Expression Language) you can use the . dot operator to access getter methods using "property name" (the getter method name without the get prefix), all just according the Javabean specification.

That said, you really need to cleanup the "answers" in your previous topic as they adds noise to the question. Also read the comments I posted in your "answers".

You can try to apply new architecture approach anounced at Google I/O 2017.

It also includes new ORM library called Room

It contains three main components: @Entity, @Dao and @Database

User.java

@Entity
public class User {
  @PrimaryKey
  private int uid;

  @ColumnInfo(name = "first_name")
  private String firstName;

  @ColumnInfo(name = "last_name")
  private String lastName;

  // Getters and setters are ignored for brevity,
  // but they're required for Room to work.
}

UserDao.java

@Dao
public interface UserDao {
  @Query("SELECT * FROM user")
  List<User> getAll();

  @Query("SELECT * FROM user WHERE uid IN (:userIds)")
  List<User> loadAllByIds(int[] userIds);

  @Query("SELECT * FROM user WHERE first_name LIKE :first AND "
       + "last_name LIKE :last LIMIT 1")
  User findByName(String first, String last);

  @Insert
  void insertAll(User... users);

  @Delete
  void delete(User user);
}

AppDatabase.java

@Database(entities = {User.class}, version = 1)
public abstract class AppDatabase extends RoomDatabase {
  public abstract UserDao userDao();
}

The nuget.exe utility doesn't have this feature, but seeing that the NuGet cache is simply a folder on your computer, you can delete the files manually. Just add this to your batch file:

del %LOCALAPPDATA%\NuGet\Cache\*.nupkg /q

Now you should be able to do it directly in the IB.

Not sure though, if this was available when the question was posted originally.

Starting with SQL SERVER 2012, you can use the OFFSET FETCH Clause:

USE AdventureWorks;
GO
SELECT SalesOrderID, OrderDate
FROM Sales.SalesOrderHeader 
ORDER BY SalesOrderID
    OFFSET 10 ROWS
    FETCH NEXT 10 ROWS ONLY;
GO

http://msdn.microsoft.com/en-us/library/ms188385(v=sql.110).aspx

This may not work correctly when the order by is not unique.

If the query is modified to ORDER BY OrderDate, the result set returned is not as expected.

The other answers here adequately explain the security caveats which are also mentioned in the subprocess documentation. But in addition to that, the overhead of starting a shell to start the program you want to run is often unnecessary and definitely silly for situations where you don't actually use any of the shell's functionality. Moreover, the additional hidden complexity should scare you, especially if you are not very familiar with the shell or the services it provides.

Where the interactions with the shell are nontrivial, you now require the reader and maintainer of the Python script (which may or may not be your future self) to understand both Python and shell script. Remember the Python motto "explicit is better than implicit"; even when the Python code is going to be somewhat more complex than the equivalent (and often very terse) shell script, you might be better off removing the shell and replacing the functionality with native Python constructs. Minimizing the work done in an external process and keeping control within your own code as far as possible is often a good idea simply because it improves visibility and reduces the risks of -- wanted or unwanted -- side effects.

Wildcard expansion, variable interpolation, and redirection are all simple to replace with native Python constructs. A complex shell pipeline where parts or all cannot be reasonably rewritten in Python would be the one situation where perhaps you could consider using the shell. You should still make sure you understand the performance and security implications.

In the trivial case, to avoid shell=True, simply replace

subprocess.Popen("command -with -options 'like this' and\\ an\\ argument", shell=True)

with

subprocess.Popen(['command', '-with','-options', 'like this', 'and an argument'])

Notice how the first argument is a list of strings to pass to execvp(), and how quoting strings and backslash-escaping shell metacharacters is generally not necessary (or useful, or correct). Maybe see also When to wrap quotes around a shell variable?

If you don't want to figure this out yourself, the shlex.split() function can do this for you. It's part of the Python standard library, but of course, if your shell command string is static, you can just run it once, during development, and paste the result into your script.

As an aside, you very often want to avoid Popen if one of the simpler wrappers in the subprocess package does what you want. If you have a recent enough Python, you should probably use subprocess.run.

• With check=True it will fail if the command you ran failed.
• With stdout=subprocess.PIPE it will capture the command's output.
• With text=True (or somewhat obscurely, with the synonym universal_newlines=True) it will decode output into a proper Unicode string (it's just bytes in the system encoding otherwise, on Python 3).

If not, for many tasks, you want check_output to obtain the output from a command, whilst checking that it succeeded, or check_call if there is no output to collect.

I'll close with a quote from David Korn: "It's easier to write a portable shell than a portable shell script." Even subprocess.run('echo "$HOME"', shell=True) is not portable to Windows.

The keyword you're looking for is super. See this guide, for instance.

You can use the %in% operator:

vec <- c(1, 2, 3, 4, 5)
1 %in% vec # true
10 %in% vec # false

In my case I did something like this, based on Luis's answer:

...State object...
userInfo = {
name: '...',
...
}

...Reducer's code...
case CHANGED_INFO:
return {
  ...state,
  userInfo: {
    ...state.userInfo,
    // I'm sending the arguments like this: changeInfo({ id: e.target.id, value: e.target.value }) and use them as below in reducer!
    [action.data.id]: action.data.value,
  },
};

Based on @Peter Baley answer, I created a more generic function:

   @objectId: HTML object ID
   @values: can be a string or an array. String is less "secure" (should not contain repeated value).
   function checkMultiValues(objectId, values){
        selectMultiObject=document.getElementById(objectId);
        for ( var i = 0, l = selectMultiObject.options.length, o; i < l; i++ )
        {
          o = selectMultiObject.options[i];
          if ( values.indexOf( o.value ) != -1 )
          {
            o.selected = true;
          } else {
            o.selected = false;
          }
        }
    }

Example: checkMultiValues('thisMultiHTMLObject','a,b,c,d');

Open a PL/SQL object in the Editor.

You can create an alias in .bashrc file as follows

alias vg='valgrind --leak-check=full -v --track-origins=yes --log-file=vg_logfile.out'

So whenever you want to check memory leaks, just do simply

vg ./<name of your executable> <command line parameters to your executable>

This will generate a Valgrind log file in the current directory.

You should use :

<img src="http://img705.imageshack.us/img705/119/original120x75.png" style="height:100px;width:100px;" alt="25"/>

That should work!!

If you want to create class then :

.size {
width:100px;
height:100px;
}

and then apply it like :

<img src="http://img705.imageshack.us/img705/119/original120x75.png" class="size" alt="25"/>

by creating a class you can use it at multiple places.

If you want to use only at one place then use inline CSS. Also Inline CSS overrides other CSS.

Following things are not mentioned in the existing answers : Buffer size configuration HTTP Header and Nesting.

Buffer size configuration for ob_start :

ob_start(null, 4096); // Once the buffer size exceeds 4096 bytes, PHP automatically executes flush, ie. the buffer is emptied and sent out.

The above code improve server performance as PHP will send bigger chunks of data, for example, 4KB (wihout ob_start call, php will send each echo to the browser).

If you start buffering without the chunk size (ie. a simple ob_start()), then the page will be sent once at the end of the script.

Output buffering does not affect the HTTP headers, they are processed in different way. However, due to buffering you can send the headers even after the output was sent, because it is still in the buffer.

ob_start();  // turns on output buffering
$foo->bar();  // all output goes only to buffer
ob_clean();  // delete the contents of the buffer, but remains buffering active
$foo->render(); // output goes to buffer
ob_flush(); // send buffer output
$none = ob_get_contents();  // buffer content is now an empty string
ob_end_clean();  // turn off output buffering

Nicely explained here : https://phpfashion.com/everything-about-output-buffering-in-php

If accessing/printing single element lists (e.g., sequentially or filtered):

my_list = [u'String'] # sample element
my_list = [str(my_list[0])]

layout_margin is a constraint that a view child tell to its parent. However it is the parent's role to choose whether to allow margin or not. Basically by setting android:layout_margin="10dp", the child is pleading the parent view group to allocate space that is 10dp bigger than its actual size. (padding="10dp", on the other hand, means the child view will make its own content 10dp smaller.)

Consequently, not all ViewGroups respect margin. The most notorious example would be listview, where the margins of items are ignored. Before you call setMargin() to a LayoutParam, you should always make sure that the current view is living in a ViewGroup that supports margin (e.g. LinearLayouot or RelativeLayout), and cast the result of getLayoutParams() to the specific LayoutParams you want. (ViewGroup.LayoutParams does not even have setMargins() method!)

The function below should do the trick. However make sure you substitute RelativeLayout to the type of the parent view.

private void setMargin(int marginInPx) {
    RelativeLayout.LayoutParams lp = (RelativeLayout.LayoutParams) getLayoutParams();
    lp.setMargins(marginInPx,marginInPx, marginInPx, marginInPx);
    setLayoutParams(lp);
}

Firefox is more stringent than other browsers and will require proper installation of an intermediate server certificate. This can be supplied by the cert authority the certificate was purchased from. the intermediate cert is typically installed in the same location as the server cert and requires the proper entry in the httpd.conf file.

while many are chastising Firefox for it's (generally) exclusive 'flagging' of this, it's actually demonstrating a higher level of security standards.

TryParse does not return the value, it returns a status code to indicate whether the parse succeeded (and doesn't throw an exception).

How about you creat a batch file with the command you want, and call it with Process.Start

dir.bat content:

dir

then call:

Process.Start("dir.bat");

Will call the bat file and execute the dir

Assuming you already know how to write a view in Flask that responds to a url, create one that reads the request.post data. To add the input box to this post data create a form on your page with the text box. You can then use jquery to do

var data = $('#<form-id>').serialize()

and then post to your view asynchronously using something like the below.

$.post('<your view url>', function(data) {
  $('.result').html(data);
});

This way it works`

   if ($result_array)
    to_excel($result_array->result_array(), $xls,$campos);
else {
    echo "<script>alert('There are no fields to generate a report');</script>";
    echo "<script>redirect('admin/ahm/panel'); </script>";
}`

You've got what rebase does backwards. git rebase master does what you're asking for — takes the changes on the current branch (since its divergence from master) and replays them on top of master, then sets the head of the current branch to be the head of that new history. It doesn't replay the changes from master on top of the current branch.

What is the meaning of parameter -1?

You can read -1 as dynamic number of parameters or "anything". Because of that there can be only one parameter -1 in view().

If you ask x.view(-1,1) this will output tensor shape [anything, 1] depending on the number of elements in x. For example:

import torch
x = torch.tensor([1, 2, 3, 4])
print(x,x.shape)
print("...")
print(x.view(-1,1), x.view(-1,1).shape)
print(x.view(1,-1), x.view(1,-1).shape)

Will output:

tensor([1, 2, 3, 4]) torch.Size([4])
...
tensor([[1],
        [2],
        [3],
        [4]]) torch.Size([4, 1])
tensor([[1, 2, 3, 4]]) torch.Size([1, 4])

You may have to perform a diff and put document.getElementById('name') code inside a condition, in case your component is something like this:

// using the new hooks API
function Comp(props) {
  const { isLoading, data } = props;
  useEffect(() => {
    if (data) {
      var name = document.getElementById('name').value;
    }
  }, [data]) // this diff is necessary

  if (isLoading) return <div>isLoading</div>
  return (
    <div id='name'>Comp</div>
  );
}

If diff is not performed then, you will get null.

What you have to do is to set the MinimumHeight property of the row. Not only the Height property. That's the key. Put the code bellow in the CellPainting event of the datagridview

private void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
{
   foreach(DataGridViewRow x in dataGridView1.Rows)
   {
     x.MinimumHeight = 50;
   }
}

not sure if it works outside of firefox:

callback (event){
  if (event.keyCode === event.DOM_VK_BACK_SPACE || event.keyCode === event.DOM_VK_DELETE)
    // do something
  }
}

if not, replace event.DOM_VK_BACK_SPACE with 8 and event.DOM_VK_DELETE with 46 or define them as constant (for better readability)

Following @wr. post, I get similar results (for Python3.5)

from timeit import *

stats = ["for i in range(1000): next(iter(s))",
         "for i in range(1000): \n\tfor x in s: \n\t\tbreak",
         "for i in range(1000): s.add(s.pop())"]

for stat in stats:
    t = Timer(stat, setup="s=set(range(100000))")
    try:
        print("Time for %s:\t %f"%(stat, t.timeit(number=1000)))
    except:
        t.print_exc()

Output:

Time for for i in range(1000): next(iter(s)):    0.205888
Time for for i in range(1000): 
    for x in s: 
        break:                                   0.083397
Time for for i in range(1000): s.add(s.pop()):   0.226570

However, when changing the underlying set (e.g. call to remove()) things go badly for the iterable examples (for, iter):

from timeit import *

stats = ["while s:\n\ta = next(iter(s))\n\ts.remove(a)",
         "while s:\n\tfor x in s: break\n\ts.remove(x)",
         "while s:\n\tx=s.pop()\n\ts.add(x)\n\ts.remove(x)"]

for stat in stats:
    t = Timer(stat, setup="s=set(range(100000))")
    try:
        print("Time for %s:\t %f"%(stat, t.timeit(number=1000)))
    except:
        t.print_exc()

Results in:

Time for while s:
    a = next(iter(s))
    s.remove(a):             2.938494
Time for while s:
    for x in s: break
    s.remove(x):             2.728367
Time for while s:
    x=s.pop()
    s.add(x)
    s.remove(x):             0.030272

Current Answer

Visual Studio Code has excellent search and replace capabilities across files. It is extremely fast, supports regex and live preview before replacement.

Focusing on startswith, if you are sure strings are not empty, adding a test on the first char, before the comparison, the strlen, etc., speeds things up a bit:

function startswith5b($haystack, $needle) {
    return ($haystack{0}==$needle{0})?strncmp($haystack, $needle, strlen($needle)) === 0:FALSE;
}

It is somehow (20%-30%) faster. Adding another char test, like $haystack{1}===$needle{1} does not seem to speedup things much, may even slow down.

=== seems faster than == Conditional operator (a)?b:c seems faster than if(a) b; else c;

For those asking "why not use strpos?" calling other solutions "unnecessary work"

strpos is fast, but it is not the right tool for this job.

To understand, here is a little simulation as an example:

Search a12345678c inside bcdefga12345678xbbbbb.....bbbbba12345678c

What the computer does "inside"?

    With strccmp, etc...

    is a===b? NO
    return false



    With strpos

    is a===b? NO -- iterating in haysack
    is a===c? NO
    is a===d? NO
    ....
    is a===g? NO
    is a===g? NO
    is a===a? YES
    is 1===1? YES -- iterating in needle
    is 2===3? YES
    is 4===4? YES
    ....
    is 8===8? YES
    is c===x? NO: oh God,
    is a===1? NO -- iterating in haysack again
    is a===2? NO
    is a===3? NO
    is a===4? NO
    ....
    is a===x? NO
    is a===b? NO
    is a===b? NO
    is a===b? NO
    is a===b? NO
    is a===b? NO
    is a===b? NO
    is a===b? NO
    ...
    ... may many times...
    ...
    is a===b? NO
    is a===a? YES -- iterating in needle again
    is 1===1? YES
    is 2===3? YES
    is 4===4? YES
    is 8===8? YES
    is c===c? YES YES YES I have found the same string! yay!
    was it at position 0? NOPE
    What you mean NO? So the string I found is useless? YEs.
    Damn.
    return false

Assuming strlen does not iterate the whole string (but even in that case) this is not convenient at all.

In short, decoupling success callback function from the ajax function so later you can add your own handlers without modifying the original code (observer pattern).

Something like this will do it:

Rows("12:12").Select
Selection.Delete

So in your code it would look like something like this:

Rows(CStr(rand) & ":" & CStr(rand)).Select
Selection.Delete

Use Manatee.Json https://github.com/gregsdennis/Manatee.Json/wiki/Usage

And you can convert the entire object to a string, filename.json is expected to be located in documents folder.

        var text = File.ReadAllText("filename.json");
        var json = JsonValue.Parse(text);

        while (JsonValue.Null != null)
        {
            Console.WriteLine(json.ToString());

        }
        Console.ReadLine();

I'm working on Crud for my app. This is how I did it Got Reactstrap as my dependency.

The accepted answer shows the correct way to setState but it does not lead to a well functioning select box.

import React, { useState } from "react"; 
import ReactDOM from "react-dom";

const initialValue = { id: 0,value: " --- Select a State ---" };

const options = [
    { id: 1, value: "Alabama" },
    { id: 2, value: "Georgia" },
    { id: 3, value: "Tennessee" }
];

const StateSelector = () => {   
   const [ selected, setSelected ] = useState(initialValue);  

     return (
       <div>
          <label>Select a State:</label>
          <select value={selected}>
            {selected === initialValue && 
                <option disabled value={initialValue}>{initialValue.value}</option>}
            {options.map((localState, index) => (
               <option key={localState.id} value={localState}>
                   {localState.value}
               </option>
             ))}
          </select>
        </div>
      ); 
};

const rootElement = document.getElementById("root");
ReactDOM.render(<StateSelector />, rootElement);
