You can achieve this by deploying something at a higher layer than namespaced Services, like the service loadbalancer https://github.com/kubernetes/contrib/tree/master/service-loadbalancer. If you want to restrict it to a single namespace, use "--namespace=ns" argument (it defaults to all namespaces: https://github.com/kubernetes/contrib/blob/master/service-loadbalancer/service_loadbalancer.go#L715). This works well for L7, but is a little messy for L4.

Select into creates new table for you at the time and then insert records in it from the source table. The newly created table has the same structure as of the source table.If you try to use select into for a existing table it will produce a error, because it will try to create new table with the same name. Insert into requires the table to be exist in your database before you insert rows in it.

Delete the CMakeCache.txt file and try this:

cmake -G %1 -DBUILD_SHARED_LIBS=ON -DBUILD_STATIC_LIBS=ON -DBUILD_TESTS=ON ..

You have to enter all your command-line definitions before including the path.

You do not need to use docker run.

You can do it with docker create.

From the docs:

The docker create command creates a writeable container layer over the specified image and prepares it for running the specified command. The container ID is then printed to STDOUT. This is similar to docker run -d except the container is never started.

So, you can do:

docker create -ti --name dummy IMAGE_NAME bash
docker cp dummy:/path/to/file /dest/to/file
docker rm -f dummy

Here, you never start the container. That looked beneficial to me.

I've faced same problem and came across to this thread but my problem was with upstream. Below git command worked for me.

Syntax

git checkout {remoteName}/{branch} -- {../path/file.js}

Example

git checkout upstream/develop -- public/js/index.js

These errors mean that the R code you are trying to run or source is not syntactically correct. That is, you have a typo.

To fix the problem, read the error message carefully. The code provided in the error message shows where R thinks that the problem is. Find that line in your original code, and look for the typo.

Prophylactic measures to prevent you getting the error again

The best way to avoid syntactic errors is to write stylish code. That way, when you mistype things, the problem will be easier to spot. There are many R style guides linked from the SO R tag info page. You can also use the formatR package to automatically format your code into something more readable. In RStudio, the keyboard shortcut CTRL + SHIFT + A will reformat your code.

Consider using an IDE or text editor that highlights matching parentheses and braces, and shows strings and numbers in different colours.

Common syntactic mistakes that generate these errors

Mismatched parentheses, braces or brackets

If you have nested parentheses, braces or brackets it is very easy to close them one too many or too few times.

{}}
## Error: unexpected '}' in "{}}"
{{}} # OK

Missing * when doing multiplication

This is a common mistake by mathematicians.

5x
Error: unexpected symbol in "5x"
5*x # OK

Not wrapping if, for, or return values in parentheses

This is a common mistake by MATLAB users. In R, if, for, return, etc., are functions, so you need to wrap their contents in parentheses.

if x > 0 {}
## Error: unexpected symbol in "if x"
if(x > 0) {} # OK

Not using multiple lines for code

Trying to write multiple expressions on a single line, without separating them by semicolons causes R to fail, as well as making your code harder to read.

x + 2 y * 3
## Error: unexpected symbol in "x + 2 y"
x + 2; y * 3 # OK

else starting on a new line

In an if-else statement, the keyword else must appear on the same line as the end of the if block.

if(TRUE) 1
else 2
## Error: unexpected 'else' in "else"    
if(TRUE) 1 else 2 # OK
if(TRUE) 
{
  1
} else            # also OK
{
  2
}

= instead of ==

= is used for assignment and giving values to function arguments. == tests two values for equality.

if(x = 0) {}
## Error: unexpected '=' in "if(x ="    
if(x == 0) {} # OK

Missing commas between arguments

When calling a function, each argument must be separated by a comma.

c(1 2)
## Error: unexpected numeric constant in "c(1 2"
c(1, 2) # OK

Not quoting file paths

File paths are just strings. They need to be wrapped in double or single quotes.

path.expand(~)
## Error: unexpected ')' in "path.expand(~)"
path.expand("~") # OK

Quotes inside strings

This is a common problem when trying to pass quoted values to the shell via system, or creating quoted xPath or sql queries.

Double quotes inside a double quoted string need to be escaped. Likewise, single quotes inside a single quoted string need to be escaped. Alternatively, you can use single quotes inside a double quoted string without escaping, and vice versa.

"x"y"
## Error: unexpected symbol in ""x"y"   
"x\"y" # OK
'x"y'  # OK  

Using curly quotes

So-called "smart" quotes are not so smart for R programming.

path.expand(“~”)
## Error: unexpected input in "path.expand(“"    
path.expand("~") # OK

Using non-standard variable names without backquotes

?make.names describes what constitutes a valid variable name. If you create a non-valid variable name (using assign, perhaps), then you need to access it with backquotes,

assign("x y", 0)
x y
## Error: unexpected symbol in "x y"
`x y` # OK

This also applies to column names in data frames created with check.names = FALSE.

dfr <- data.frame("x y" = 1:5, check.names = FALSE)
dfr$x y
## Error: unexpected symbol in "dfr$x y"
dfr[,"x y"] # OK
dfr$`x y`   # also OK

It also applies when passing operators and other special values to functions. For example, looking up help on %in%.

?%in%
## Error: unexpected SPECIAL in "?%in%"
?`%in%` # OK

Sourcing non-R code

The source function runs R code from a file. It will break if you try to use it to read in your data. Probably you want read.table.

source(textConnection("x y"))
## Error in source(textConnection("x y")) : 
##   textConnection("x y"):1:3: unexpected symbol
## 1: x y
##       ^

Corrupted RStudio desktop file

RStudio users have reported erroneous source errors due to a corrupted .rstudio-desktop file. These reports only occurred around March 2014, so it is possibly an issue with a specific version of the IDE. RStudio can be reset using the instructions on the support page.

Using expression without paste in mathematical plot annotations

When trying to create mathematical labels or titles in plots, the expression created must be a syntactically valid mathematical expression as described on the ?plotmath page. Otherwise the contents should be contained inside a call to paste.

plot(rnorm(10), ylab = expression(alpha ^ *)))
## Error: unexpected '*' in "plot(rnorm(10), ylab = expression(alpha ^ *"
plot(rnorm(10), ylab = expression(paste(alpha ^ phantom(0), "*"))) # OK

One thing that's not really addressed in the question or the discussion is the fact that DbContext can't cancel changes. You can submit changes, but you can't clear out the change tree, so if you use a per request context you're out of luck if you need to throw changes away for whatever reason.

Personally I create instances of DbContext when needed - usually attached to business components that have the ability to recreate the context if required. That way I have control over the process, rather than having a single instance forced onto me. I also don't have to create the DbContext at each controller startup regardless of whether it actually gets used. Then if I still want to have per request instances I can create them in the CTOR (via DI or manually) or create them as needed in each controller method. Personally I usually take the latter approach as to avoid creating DbContext instances when they are not actually needed.

It depends from which angle you look at it too. To me the per request instance has never made sense. Does the DbContext really belong into the Http Request? In terms of behavior that's the wrong place. Your business components should be creating your context, not the Http request. Then you can create or throw away your business components as needed and never worry about the lifetime of the context.

Looks like @mixin and @include are not needed for a simple case like this.

One can just do:

.myclass {
  font-weight: bold;
  font-size: 90px;
}

.myotherclass {
  @extend .myclass;
  color: #000000;
}

I've been struggling with Dialog animation today, finally got it working using styles, so here is an example.

To start with, the most important thing — I probably had it working 5 different ways today but couldn't tell because... If your devices animation settings are set to "No Animations" (Settings ? Display ? Animation) then the dialogs won't be animated no matter what you do!

The following is a stripped down version of my styles.xml. Hopefully it is self-explanatory. This should be located in res/values.

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="PauseDialog" parent="@android:style/Theme.Dialog">
        <item name="android:windowAnimationStyle">@style/PauseDialogAnimation</item>
    </style>

    <style name="PauseDialogAnimation">
        <item name="android:windowEnterAnimation">@anim/spin_in</item>
        <item name="android:windowExitAnimation">@android:anim/slide_out_right</item>
    </style>
</resources>

The windowEnterAnimation is one of my animations and is located in res\anim. The windowExitAnimation is one of the animations that is part of the Android SDK.

Then when I create the Dialog in my activities onCreateDialog(int id) method I do the following.

Dialog dialog = new Dialog(this, R.style.PauseDialog);

// Setting the title and layout for the dialog
dialog.setTitle(R.string.pause_menu_label);
dialog.setContentView(R.layout.pause_menu);

Alternatively you could set the animations the following way instead of using the Dialog constructor that takes a theme.

Dialog dialog = new Dialog(this);
dialog.getWindow().getAttributes().windowAnimations = R.style.PauseDialogAnimation;

C didn't use to have consts, so #defines were the only way of providing constant values. Both C and C++ do have them now, so there is no point in using them, except when they are going to be tested with #ifdef/ifndef.

This sometimes happens when a string is converted from Windows-1252 to UTF-8 twice.

We had this in a Zend/PHP/MySQL application where characters like that were appearing in the database, probably due to the MySQL connection not specifying the correct character set. We had to:

1. Ensure Zend and PHP were communicating with the database in UTF-8 (was not by default)

2. Repair the broken characters with several SQL queries like this...

   UPDATE MyTable SET 
   MyField1 = CONVERT(CAST(CONVERT(MyField1 USING latin1) AS BINARY) USING utf8),
   MyField2 = CONVERT(CAST(CONVERT(MyField2 USING latin1) AS BINARY) USING utf8);
   

   Do this for as many tables/columns as necessary.

You can also fix some of these strings in PHP if necessary. Note that because characters have been encoded twice, we actually need to do a reverse conversion from UTF-8 back to Windows-1252, which confused me at first.

mb_convert_encoding('’', 'Windows-1252', 'UTF-8');    // returns ’

Environment variables are 'evaluated' (ie. they are attributed) in the following order:

1. System variables
2. Variables defined in autoexec.bat
3. User variables

Every process has an environment block that contains a set of environment variables and their values. There are two types of environment variables: user environment variables (set for each user) and system environment variables (set for everyone). A child process inherits the environment variables of its parent process by default.

Programs started by the command processor inherit the command processor's environment variables.

Environment variables specify search paths for files, directories for temporary files, application-specific options, and other similar information. The system maintains an environment block for each user and one for the computer. The system environment block represents environment variables for all users of the particular computer. A user's environment block represents the environment variables the system maintains for that particular user, including the set of system environment variables.

Why

I've been not satisfied with all the solutions on this page (come on, where is our favorite copy-paste thing?) so I wrote my own based on answers here. It tries to be complete and more Pythonic. I've added a handler for dict and bool values in arguments to be more consumer-side (JS) friendly, but they are yet optional, you can drop them.

How it works

Test 1: Adding new arguments, handling Arrays and Bool values:

url = 'http://stackoverflow.com/test'
new_params = {'answers': False, 'data': ['some','values']}

add_url_params(url, new_params) == \
    'http://stackoverflow.com/test?data=some&data=values&answers=false'

Test 2: Rewriting existing args, handling DICT values:

url = 'http://stackoverflow.com/test/?question=false'
new_params = {'question': {'__X__':'__Y__'}}

add_url_params(url, new_params) == \
    'http://stackoverflow.com/test/?question=%7B%22__X__%22%3A+%22__Y__%22%7D'

Talk is cheap. Show me the code.

Code itself. I've tried to describe it in details:

from json import dumps

try:
    from urllib import urlencode, unquote
    from urlparse import urlparse, parse_qsl, ParseResult
except ImportError:
    # Python 3 fallback
    from urllib.parse import (
        urlencode, unquote, urlparse, parse_qsl, ParseResult
    )


def add_url_params(url, params):
    """ Add GET params to provided URL being aware of existing.

    :param url: string of target URL
    :param params: dict containing requested params to be added
    :return: string with updated URL

    >> url = 'http://stackoverflow.com/test?answers=true'
    >> new_params = {'answers': False, 'data': ['some','values']}
    >> add_url_params(url, new_params)
    'http://stackoverflow.com/test?data=some&data=values&answers=false'
    """
    # Unquoting URL first so we don't loose existing args
    url = unquote(url)
    # Extracting url info
    parsed_url = urlparse(url)
    # Extracting URL arguments from parsed URL
    get_args = parsed_url.query
    # Converting URL arguments to dict
    parsed_get_args = dict(parse_qsl(get_args))
    # Merging URL arguments dict with new params
    parsed_get_args.update(params)

    # Bool and Dict values should be converted to json-friendly values
    # you may throw this part away if you don't like it :)
    parsed_get_args.update(
        {k: dumps(v) for k, v in parsed_get_args.items()
         if isinstance(v, (bool, dict))}
    )

    # Converting URL argument to proper query string
    encoded_get_args = urlencode(parsed_get_args, doseq=True)
    # Creating new parsed result object based on provided with new
    # URL arguments. Same thing happens inside of urlparse.
    new_url = ParseResult(
        parsed_url.scheme, parsed_url.netloc, parsed_url.path,
        parsed_url.params, encoded_get_args, parsed_url.fragment
    ).geturl()

    return new_url

Please be aware that there may be some issues, if you'll find one please let me know and we will make this thing better

(Not cross-browser tested), but this is my answer:

.btn-circle {
  width: 40px;
  height: 40px;
  line-height: 40px; /* adjust line height to align vertically*/
  padding:0;
  border-radius: 50%;
}

• vertical center via the line-height property
• padding becomes useless and must be reset
• border-radius independant of the button size

Have you tried starting it as an administrator? Start Visual Studio as an administrator if you use it, because working with .bat files requires those privileges.

Both perform shallow copies as @PatrickDesjardins said (despite the many misled souls who think that CopyTo does a deep copy).

However, CopyTo allows you to copy one array to a specified index in the destination array, giving it significantly more flexibility.

return filename.split('.').pop();

Keep it simple :)

Edit:

This is another non-regex solution that I believe is more efficient:

return filename.substring(filename.lastIndexOf('.')+1, filename.length) || filename;

There are some corner cases that are better handled by VisioN's answer below, particularly files with no extension (.htaccess etc included).

It's very performant, and handles corner cases in an arguably better way by returning "" instead of the full string when there's no dot or no string before the dot. It's a very well crafted solution, albeit tough to read. Stick it in your helpers lib and just use it.

Old Edit:

A safer implementation if you're going to run into files with no extension, or hidden files with no extension (see VisioN's comment to Tom's answer above) would be something along these lines

var a = filename.split(".");
if( a.length === 1 || ( a[0] === "" && a.length === 2 ) ) {
    return "";
}
return a.pop();    // feel free to tack .toLowerCase() here if you want

If a.length is one, it's a visible file with no extension ie. file

If a[0] === "" and a.length === 2 it's a hidden file with no extension ie. .htaccess

Hope this helps to clear up issues with the slightly more complex cases. In terms of performance, I believe this solution is a little slower than regex in most browsers. However, for most common purposes this code should be perfectly usable.

For me, this issue arose due to an incompatible combination of plugin and gradle.

I added these to the code to have it working:

Main build.gradle

dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0'
    }

Main gradle-wrapper.properties:

distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-all.zip

Imagine you have a class called A with the following declaration.

class A  
{  
    public:  
        A();

    private:
        int m_value;
};

You want the program to stop when someone modifies the value of "m_value".

Go to the class definition and put a breakpoint in the constructor of A.

A::A()
{
    ... // set breakpoint here
}

Once we stopped the program:

Debug -> New Breakpoint -> New Data Breakpoint ...

Address: &(this->m_value)
Byte Count: 4 (Because int has 4 bytes)

Now, we can resume the program. The debugger will stop when the value is changed.

You can do the same with inherited classes or compound classes.

class B
{
   private:
       A m_a;
};

Address: &(this->m_a.m_value)

If you don't know the number of bytes of the variable you want to inspect, you can use the sizeof operator.

For example:

// to know the size of the word processor,  
// if you want to inspect a pointer.
int wordTam = sizeof (void* ); 

If you look at the "Call stack" you can see the function that changed the value of the variable.

To quickly find a meaningful error message by inspecting the error during debugging:

• Add a quick watch for:

  ((System.Data.Entity.Validation.DbEntityValidationException)$exception).EntityValidationErrors
  

• Drill down into EntityValidationErrors like this:

  (collection item e.g. [0]) > ValidationErrors > (collection item e.g. [0]) > ErrorMessage

The easiest way is to use the 'plumbing' command update-ref to delete the current branch.

You can't use git branch -D as it has a safety valve to stop you deleting the current branch.

This puts you back into the 'initial commit' state where you can start with a fresh initial commit.

git update-ref -d refs/heads/master
git commit -m "New initial commit"

I encountered a similar error after upgrading to RC5; i.e. Angular 2: Can't bind to 'ngModel' since it isn't a known property of 'input'.

The code on Plunker show you using Angular2 RC4, but the example code at https://angular.io/docs/ts/latest/cookbook/dynamic-form.html is using NGModule which is part of RC5. NGModules is a breaking change from RC4 to RC5.

This page explains the migration from RC4 to RC5: https://angular.io/docs/ts/latest/cookbook/rc4-to-rc5.html

I hope this addresses the error you're getting and help get you going in the right direction.

In short, I had to create an NGModule in app.module.ts:

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule }   from '@angular/forms';

import { AppComponent }  from './app.component';

@NgModule({
    imports:      [ BrowserModule, FormsModule ],
    declarations: [ AppComponent ],
    bootstrap:    [ AppComponent ]
})
export class AppModule { }

I then changed main.ts to use the module:

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app.module';

platformBrowserDynamic().bootstrapModule(AppModule);

Of course, I also needed to update the dependencies in package.json. Here's my dependencies from package.json. Admittedly, I've hobbled them together from other sources (maybe the ng docs examples), so your mileage may vary:

...
"dependencies": {
    "@angular/common": "2.0.0-rc.5",
    "@angular/compiler": "2.0.0-rc.5",
    "@angular/core": "2.0.0-rc.5",
    "@angular/forms": "0.3.0",
    "@angular/http": "2.0.0-rc.5",
    "@angular/platform-browser": "2.0.0-rc.5",
    "@angular/platform-browser-dynamic": "2.0.0-rc.5",
    "@angular/router": "3.0.0-rc.1",
    "@angular/router-deprecated": "2.0.0-rc.2",
    "@angular/upgrade": "2.0.0-rc.5",
    "systemjs": "0.19.27",
    "core-js": "^2.4.0",
    "reflect-metadata": "^0.1.3",
    "rxjs": "5.0.0-beta.6",
    "zone.js": "^0.6.12",
    "angular2-in-memory-web-api": "0.0.15",
    "bootstrap": "^3.3.6"
  },
...

I hope this helps better. :-)

You could really, really, really optimize your code a lot by paying the price of creating the delegate only once (there's also no need to instantiate the class to call an static method). I've done something very similar, and I just cache a delegate to the "Run" method with the help of a helper class :-). It looks like this:

static class Indent{    
     public static void Run(){
         // implementation
     }
     // other helper methods
}

static class MacroRunner {

    static MacroRunner() {
        BuildMacroRunnerList();
    }

    static void BuildMacroRunnerList() {
        macroRunners = System.Reflection.Assembly.GetExecutingAssembly()
            .GetTypes()
            .Where(x => x.Namespace.ToUpper().Contains("MACRO"))
            .Select(t => (Action)Delegate.CreateDelegate(
                typeof(Action), 
                null, 
                t.GetMethod("Run", System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.Public)))
            .ToList();
    }

    static List<Action> macroRunners;

    public static void Run() {
        foreach(var run in macroRunners)
            run();
    }
}

It is MUCH faster this way.

If your method signature is different from Action you could replace the type-casts and typeof from Action to any of the needed Action and Func generic types, or declare your Delegate and use it. My own implementation uses Func to pretty print objects:

static class PrettyPrinter {

    static PrettyPrinter() {
        BuildPrettyPrinterList();
    }

    static void BuildPrettyPrinterList() {
        printers = System.Reflection.Assembly.GetExecutingAssembly()
            .GetTypes()
            .Where(x => x.Name.EndsWith("PrettyPrinter"))
            .Select(t => (Func<object, string>)Delegate.CreateDelegate(
                typeof(Func<object, string>), 
                null, 
                t.GetMethod("Print", System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.Public)))
            .ToList();
    }

    static List<Func<object, string>> printers;

    public static void Print(object obj) {
        foreach(var printer in printers)
            print(obj);
    }
}

Try like this:

$data = array('current_login' => date('Y-m-d H:i:s'));
$this->db->set('last_login', 'current_login', false);
$this->db->where('id', 'some_id');
$this->db->update('login_table', $data);

Pay particular attention to the set() call's 3rd parameter. false prevents CodeIgniter from quoting the 2nd parameter -- this allows the value to be treated as a table column and not a string value. For any data that doesn't need to special treatment, you can lump all of those declarations into the $data array.

The query generated by above code:

UPDATE `login_table`
SET last_login = current_login, `current_login` = '2018-01-18 15:24:13'
WHERE `id` = 'some_id'

You have to use CASE Statement/Expression

Select * from Customer
WHERE  (I.IsClose=@ISClose OR @ISClose is NULL)  
AND    
    (C.FirstName like '%'+@ClientName+'%' or @ClientName is NULL )    
AND 
     CASE @Value
         WHEN 2 THEN (CASE I.RecurringCharge WHEN @Total or @Total is NULL) 
         WHEN 3 THEN (CASE WHEN I.RecurringCharge like 
                               '%'+cast(@Total as varchar(50))+'%' 
                     or @Total is NULL )
     END

You can use Unicode strings, they have a method to do just what you want:

>>> s = u"345"
>>> s.isnumeric()
True

Or:

>>> s = "345"
>>> u = unicode(s)
>>> u.isnumeric()
True

http://www.tutorialspoint.com/python/string_isnumeric.htm

http://docs.python.org/2/howto/unicode.html

For those who just need to save some int value in the resources, you can do the following.

integers.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <integer name="default_value">100</integer>
</resources> 

Code

int defaultValue = getResources().getInteger(R.integer.default_value);

When it is matter of mysql how to count or get how many rows in a table with PHP PDO I use this

// count total number of rows
$query = "SELECT COUNT(*) as total_rows FROM sometable";
$stmt = $con->prepare($query);

// execute query
$stmt->execute();

// get total rows
$row = $stmt->fetch(PDO::FETCH_ASSOC);
$total_rows = $row['total_rows'];

My solution was to not use the id of an anchor element: <a id='star_wars'>Place to jump to</a>. Apparently blazor and other spa frameworks have issues jumping to anchors on the same page. To get around that I had to use document.getElementById('star_wars'). However this didn't work until I put the id in a paragraph element instead: <p id='star_wars'>Some paragraph<p>.

Example using bootstrap:

<button class="btn btn-link" onclick="document.getElementById('star_wars').scrollIntoView({behavior:'smooth'})">Star Wars</button>

... lots of other text

<p id="star_wars">Star Wars is an American epic...</p>

See https://code.angularjs.org/1.4.10/docs/api/ngRoute/provider/$routeProvider

[reloadOnSearch=true] - {boolean=} - reload route when only $location.search() or $location.hash() changes.

Setting this to false did the trick without all of the above for me.

If even after importing the formsmodule the problem persists, check that your Input does not have a "name" attribute with value equal to another input on page.

std::less<> when using custom classes with operator<

If you are dealing with a set of your custom class that has operator< defined, then you can just use std::less<>.

As mentioned at http://en.cppreference.com/w/cpp/container/set/find C++14 has added two new find APIs:

template< class K > iterator find( const K& x );
template< class K > const_iterator find( const K& x ) const;

which allow you to do:

main.cpp

#include <cassert>
#include <set>

class Point {
    public:
        // Note that there is _no_ conversion constructor,
        // everything is done at the template level without
        // intermediate object creation.
        //Point(int x) : x(x) {}
        Point(int x, int y) : x(x), y(y) {}
        int x;
        int y;
};
bool operator<(const Point& c, int x) { return c.x < x; }
bool operator<(int x, const Point& c) { return x < c.x; }
bool operator<(const Point& c, const Point& d) {
    return c.x < d;
}

int main() {
    std::set<Point, std::less<>> s;
    s.insert(Point(1, -1));
    s.insert(Point(2, -2));
    s.insert(Point(0,  0));
    s.insert(Point(3, -3));
    assert(s.find(0)->y ==  0);
    assert(s.find(1)->y == -1);
    assert(s.find(2)->y == -2);
    assert(s.find(3)->y == -3);
    // Ignore 1234, find 1.
    assert(s.find(Point(1, 1234))->y == -1);
}

Compile and run:

g++ -std=c++14 -Wall -Wextra -pedantic -o main.out main.cpp
./main.out

Tested on Ubuntu 16.10, g++ 6.2.0.

• Closed all my VS windows
• Started the Visual Studio Installer and clicked 'Modify'.
• Under 'Individual components' > 'Code Tools' > Deselected NuGet package manager and re-selected it.
• After modifying and restarting VS, IntelliSense was working correctly again.

The dataframe.sort() method is - so my understanding - deprecated in pandas > 0.18. In order to solve your problem you should use dataframe.sort_values() instead:

f.sort_values(by=["c1","c2"], ascending=[False, True])

The output looks like this:

    c1  c2
    3   10
    2   15
    2   30
    2   100
    1   20

This is my benchmark results

test 4,267,740 ops/sec ±1.32% (60 runs sampled)

exec 3,649,719 ops/sec ±2.51% (60 runs sampled)

match 3,623,125 ops/sec ±1.85% (62 runs sampled)

indexOf 6,230,325 ops/sec ±0.95% (62 runs sampled)

test method is faster than the match method, but the fastest method is the indexOf

To completely remove the style attribute of the voltaic_holder span, do this:

$("#voltaic_holder").removeAttr("style");

To add an attribute, do this:

$("#voltaic_holder").attr("attribute you want to add", "value you want to assign to attribute");

To remove only the top style, do this:

$("#voltaic_holder").css("top", "");

\t is a tab character. Use a raw string instead:

test_file=open(r'c:\Python27\test.txt','r')

or double the slashes:

test_file=open('c:\\Python27\\test.txt','r')

or use forward slashes instead:

test_file=open('c:/Python27/test.txt','r')

You could look at "XpathNavigator.Evaluate" I have used this to process mathematical expressions for my GridView and it works fine for me.

Here is the code I used for my program:

public static double Evaluate(string expression)
{
    return (double)new System.Xml.XPath.XPathDocument
    (new StringReader("<r/>")).CreateNavigator().Evaluate
    (string.Format("number({0})", new
    System.Text.RegularExpressions.Regex(@"([\+\-\*])")
    .Replace(expression, " ${1} ")
    .Replace("/", " div ")
    .Replace("%", " mod ")));
}

I looked into this as well, and after comparing the SqlDataAdapter.Fill method with the SqlDataReader.Load funcitons, I've found that the SqlDataAdapter.Fill method is more than twice as fast with the result sets I've been using

Used code:

    [TestMethod]
    public void SQLCommandVsAddaptor()
    {
        long AdapterFillLargeTableTime, readerLoadLargeTableTime, AdapterFillMediumTableTime, readerLoadMediumTableTime, AdapterFillSmallTableTime, readerLoadSmallTableTime, AdapterFillTinyTableTime, readerLoadTinyTableTime;

        string LargeTableToFill = "select top 10000 * from FooBar";
        string MediumTableToFill = "select top 1000 * from FooBar";
        string SmallTableToFill = "select top 100 * from FooBar";
        string TinyTableToFill = "select top 10 * from FooBar";

        using (SqlConnection sconn = new SqlConnection("Data Source=.;initial catalog=Foo;persist security info=True; user id=bar;password=foobar;"))
        {
            // large data set measurements
            AdapterFillLargeTableTime = MeasureExecutionTimeMethod(sconn, LargeTableToFill, ExecuteDataAdapterFillStep);
            readerLoadLargeTableTime = MeasureExecutionTimeMethod(sconn, LargeTableToFill, ExecuteSqlReaderLoadStep);
            // medium data set measurements
            AdapterFillMediumTableTime = MeasureExecutionTimeMethod(sconn, MediumTableToFill, ExecuteDataAdapterFillStep);
            readerLoadMediumTableTime = MeasureExecutionTimeMethod(sconn, MediumTableToFill, ExecuteSqlReaderLoadStep);
            // small data set measurements
            AdapterFillSmallTableTime = MeasureExecutionTimeMethod(sconn, SmallTableToFill, ExecuteDataAdapterFillStep);
            readerLoadSmallTableTime = MeasureExecutionTimeMethod(sconn, SmallTableToFill, ExecuteSqlReaderLoadStep);
            // tiny data set measurements
            AdapterFillTinyTableTime = MeasureExecutionTimeMethod(sconn, TinyTableToFill, ExecuteDataAdapterFillStep);
            readerLoadTinyTableTime = MeasureExecutionTimeMethod(sconn, TinyTableToFill, ExecuteSqlReaderLoadStep);
        }
        using (StreamWriter writer = new StreamWriter("result_sql_compare.txt"))
        {
            writer.WriteLine("10000 rows");
            writer.WriteLine("Sql Data Adapter 100 times table fill speed 10000 rows: {0} milliseconds", AdapterFillLargeTableTime);
            writer.WriteLine("Sql Data Reader 100 times table load speed 10000 rows: {0} milliseconds", readerLoadLargeTableTime);
            writer.WriteLine("1000 rows");
            writer.WriteLine("Sql Data Adapter 100 times table fill speed 1000 rows: {0} milliseconds", AdapterFillMediumTableTime);
            writer.WriteLine("Sql Data Reader 100 times table load speed 1000 rows: {0} milliseconds", readerLoadMediumTableTime);
            writer.WriteLine("100 rows");
            writer.WriteLine("Sql Data Adapter 100 times table fill speed 100 rows: {0} milliseconds", AdapterFillSmallTableTime);
            writer.WriteLine("Sql Data Reader 100 times table load speed 100 rows: {0} milliseconds", readerLoadSmallTableTime);
            writer.WriteLine("10 rows");
            writer.WriteLine("Sql Data Adapter 100 times table fill speed 10 rows: {0} milliseconds", AdapterFillTinyTableTime);
            writer.WriteLine("Sql Data Reader 100 times table load speed 10 rows: {0} milliseconds", readerLoadTinyTableTime);

        }
        Process.Start("result_sql_compare.txt");
    }

    private long MeasureExecutionTimeMethod(SqlConnection conn, string query, Action<SqlConnection, string> Method)
    {
        long time; // know C#
        // execute single read step outside measurement time, to warm up cache or whatever
        Method(conn, query);
        // start timing
        time = Environment.TickCount;
        for (int i = 0; i < 100; i++)
        {
            Method(conn, query);
        }
        // return time in milliseconds
        return Environment.TickCount - time;
    }

    private void ExecuteDataAdapterFillStep(SqlConnection conn, string query)
    {
        DataTable tab = new DataTable();
        conn.Open();
        using (SqlDataAdapter comm = new SqlDataAdapter(query, conn))
        {
            // Adapter fill table function
            comm.Fill(tab);
        }
        conn.Close();
    }

    private void ExecuteSqlReaderLoadStep(SqlConnection conn, string query)
    {
        DataTable tab = new DataTable();
        conn.Open();
        using (SqlCommand comm = new SqlCommand(query, conn))
        {
            using (SqlDataReader reader = comm.ExecuteReader())
            {
                // IDataReader Load function
                tab.Load(reader);
            }
        }
        conn.Close();
    }

Results:

10000 rows:
Sql Data Adapter 100 times table fill speed 10000 rows: 11782 milliseconds
Sql Data Reader  100 times table load speed 10000 rows: 26047 milliseconds
1000 rows:
Sql Data Adapter 100 times table fill speed 1000 rows: 984  milliseconds
Sql Data Reader  100 times table load speed 1000 rows: 2031 milliseconds
100 rows:
Sql Data Adapter 100 times table fill speed 100 rows: 125 milliseconds
Sql Data Reader  100 times table load speed 100 rows: 235 milliseconds
10 rows:
Sql Data Adapter 100 times table fill speed 10 rows: 32 milliseconds
Sql Data Reader  100 times table load speed 10 rows: 93 milliseconds

For performance issues, using the SqlDataAdapter.Fill method is far more efficient. So unless you want to shoot yourself in the foot use that. It works faster for small and large data sets.

Put these methods in your Util class and use anywhere.

Kotlin

fun hideKeyboard(activity: Activity) {
    val view = activity.currentFocus
    val methodManager = activity.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    assert(view != null)
    methodManager.hideSoftInputFromWindow(view!!.windowToken, InputMethodManager.HIDE_NOT_ALWAYS)
}

private fun showKeyboard(activity: Activity) {
    val view = activity.currentFocus
    val methodManager = activity.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    assert(view != null)
    methodManager.showSoftInput(view, InputMethodManager.SHOW_IMPLICIT)
}

Java

public static void hideKeyboard(Activity activity) {
    View view = activity.getCurrentFocus();
    InputMethodManager methodManager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
    assert methodManager != null && view != null;
    methodManager.hideSoftInputFromWindow(view.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
}

private static void showKeyboard(Activity activity) {
    View view = activity.getCurrentFocus();
    InputMethodManager methodManager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
    assert methodManager != null && view != null;
    methodManager.showSoftInput(view, InputMethodManager.SHOW_IMPLICIT);
}

The following bash script will display the package name and the main activity name:

apk_package.sh

package=$(aapt dump badging "$*" | awk '/package/{gsub("name=|'"'"'","");  print $2}')
activity=$(aapt dump badging "$*" | awk '/activity/{gsub("name=|'"'"'","");  print $2}')
echo
echo "   file : $1"
echo "package : $package"
echo "activity: $activity"

run it like so:

apk_package.sh /path/to/my.apk

I notice that recent Oracle client installers change file permissions.

I had Oracle 12.0.1 32 bit client installed for a year. I recently installed Oracle 12.0.1 64 bit client. The Oracle install change ALL file permissions in the 32 bit folders.

My application suddenly failed to run.

I used PROCMON.EXE (https://docs.microsoft.com/en-us/sysinternals/downloads/) and noticed that permission was denied opening OCI.DLL

I changed the permissions for everything in the Oracle client folders and application works as expected.

Usually you also want the master checkbox to be unchecked if at least 1 slave checkbox is unchecked and to be ckecked if all slave checkboxes are checked:

/**
 * Checks and unchecks checkbox-group with a master checkbox and slave checkboxes
 * @param masterId is the id of master checkbox
 * @param slaveName is the name of slave checkboxes
 */
function checkAll(masterId, slaveName) {
    $master = $('#' + masterId);
    $slave = $('input:checkbox[name=' + slaveName + ']');

    $master.click(function(){
        $slave.prop('checked', $(this).prop('checked'));
        $slave.trigger('change');
    });

    $slave.change(function() {
        if ($master.is(':checked') && $slave.not(':checked').length > 0) {
            $master.prop('checked', false);
        } else if ($master.not(':checked') && $slave.not(':checked').length == 0) {
        $master.prop('checked', 'checked');
    }
    });
}

And if you want to enable any control (e.g. Remove All button or a Add Something button), when at least one checkbox is checked and disable when no checkbox is checked:

/**
 * Checks and unchecks checkbox-group with a master checkbox and slave checkboxes,
 * enables or disables a control when a checkbox is checked
 * @param masterId is the id of master checkbox
 * @param slaveName is the name of slave checkboxes
 */
function checkAllAndSwitchControl(masterId, slaveName, controlId) {
    $master = $('#' + masterId);
    $slave = $('input:checkbox[name=' + slaveName + ']');

    $master.click(function(){
        $slave.prop('checked', $(this).prop('checked'));
        $slave.trigger('change');
    });

    $slave.change(function() {
        switchControl(controlId, $slave.filter(':checked').length > 0);
        if ($master.is(':checked') && $slave.not(':checked').length > 0) {
            $master.prop('checked', false);
        } else if ($master.not(':checked') && $slave.not(':checked').length == 0) {
        $master.prop('checked', 'checked');
    }
    });
}

/**
 * Enables or disables a control
 * @param controlId is the control-id
 * @param enable is true, if control must be enabled, or false if not
 */
function switchControl(controlId, enable) {
    var $control = $('#' + controlId);
    if (enable) {
        $control.removeProp('disabled');
    } else {
        $control.prop('disabled', 'disabled');
    }
}

To multiply, use mult for signed multiplication and multu for unsigned multiplication. Note that the result of the multiplication of two 32-bit numbers yields a 64-number. If you want the result back in $v0 that means that you assume the result will fit in 32 bits.

The 32 most significant bits will be held in the HI special register (accessible by mfhi instruction) and the 32 least significant bits will be held in the LO special register (accessible by the mflo instruction):

E.g.:

li $a0, 5
li $a1, 3
mult $a0, $a1
mfhi $a2 # 32 most significant bits of multiplication to $a2
mflo $v0 # 32 least significant bits of multiplication to $v0

To divide, use div for signed division and divu for unsigned division. In this case, the HI special register will hold the remainder and the LO special register will hold the quotient of the division.

E.g.:

div $a0, $a1
mfhi $a2 # remainder to $a2
mflo $v0 # quotient to $v0

I am in the role of maintaining application created by offshore development team. Now I am having all kinds of issues in the application because original database schema did not contain PRIMARY KEYS on some tables. So please dont let other people suffer because of your poor design. It is always good idea to have primary keys on tables.

I used below program to use of json.loads()

import urllib.request
import json
endpoint = 'https://maps.googleapis.com/maps/api/directions/json?'
api_key = 'AIzaSyABbKiwfzv9vLBR_kCuhO7w13Kseu68lr0'
origin = input('where are you ?').replace(' ','+')
destination = input('where do u want to go').replace(' ','+')
nav_request = 'origin={}&destination={}&key={}'.format(origin,destination,api_key)
request = endpoint + nav_request
response = urllib.request.urlopen(request).read().decode('utf-8')
directions = json.loads(response)
print(directions)

$x = 1.24

$result = $x - floor($x);

echo $result; // .24

Big one I see that causes this is filename. If you have a SPACE then any number such as 'Site 2' the file path with look like something/Site%202/index.html This is because spaces or rendered as %20, and if another number is immediately following that it will try to read it as %202. Fix is you never use spaces in your filenames.

curl -K myconfig.txt -o output.txt 

Writes the first output received in the file you specify (overwrites if an old one exists).

curl -K myconfig.txt >> output.txt

Appends all output you receive to the specified file.

Note: The -K is optional.

Use git fetch && git checkout RemoteBranchName.

It works very well for me...

readFileSync() is synchronous and blocks execution until finished. These return their results as return values. readFile() are asynchronous and return immediately while they function in the background. You pass a callback function which gets called when they finish. let's take an example for non-blocking.

following method read a file as a non-blocking way

var fs = require('fs');
fs.readFile(filename, "utf8", function(err, data) {
        if (err) throw err;
        console.log(data);
});

following is read a file as blocking or synchronous way.

var data = fs.readFileSync(filename);

LOL...If you don't want readFileSync() as blocking way then take reference from the following code. (Native)

var fs = require('fs');
function readFileAsSync(){
    new Promise((resolve, reject)=>{
        fs.readFile(filename, "utf8", function(err, data) {
                if (err) throw err;
                resolve(data);
        });
    });
}

async function callRead(){
    let data = await readFileAsSync();
    console.log(data);
}

callRead();

it's mean behind scenes readFileSync() work same as above(promise) base.

i got the same problem and i notice that my security config has diferent TAGS like the @Xenolion answer says

<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">localhost</domain>
    </domain-config>
</network-security-config>

so i change the TAGS "domain-config" for "base-config" and works, like this:

<network-security-config>
    <base-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">localhost</domain>
    </base-config>
</network-security-config>

mvn clean install -U

Solved my problem. Since the repos were cached, I needed to force it to get latest version.

Until CSS 3's user-select property becomes available, Gecko-based browsers support the -moz-user-select property you already found. WebKit and Blink-based browsers support the -webkit-user-select property.

This of course is not supported in browsers that do not use the Gecko rendering engine.

There is no "standards" compliant quick-and-easy way to do it; using JavaScript is an option.

The real question is, why do you want users to not be able to highlight and presumably copy and paste certain elements? I have not come across a single time that I wanted to not let users highlight a certain portion of my website. Several of my friends, after spending many hours reading and writing code will use the highlight feature as a way to remember where on the page they were, or providing a marker so that their eyes know where to look next.

The only place I could see this being useful is if you have buttons for forms that should not be copy and pasted if a user copy and pasted the website.

1. The protocol is available as req.protocol. docs here

   1. Before express 3.0, the protocol you can assume to be http unless you see that req.get('X-Forwarded-Protocol') is set and has the value https, in which case you know that's your protocol

2. The host comes from req.get('host') as Gopal has indicated

3. Hopefully you don't need a non-standard port in your URLs, but if you did need to know it you'd have it in your application state because it's whatever you passed to app.listen at server startup time. However, in the case of local development on a non-standard port, Chrome seems to include the port in the host header so req.get('host') returns localhost:3000, for example. So at least for the cases of a production site on a standard port and browsing directly to your express app (without reverse proxy), the host header seems to do the right thing regarding the port in the URL.

4. The path comes from req.originalUrl (thanks @pgrassant). Note this DOES include the query string. docs here on req.url and req.originalUrl. Depending on what you intend to do with the URL, originalUrl may or may not be the correct value as compared to req.url.

Combine those all together to reconstruct the absolute URL.

  var fullUrl = req.protocol + '://' + req.get('host') + req.originalUrl;

Converting to a DATE or using an open-ended date range in any case will yield the best performance. FYI, convert to date using an index are the best performers. More testing a different techniques in article: What is the most efficient way to trim time from datetime? Posted by Aaron Bertrand

From that article:

DECLARE @dateVar datetime = '19700204';

-- Quickest when there is an index on t.[DateColumn], 
-- because CONVERT can still use the index.
SELECT t.[DateColumn]
FROM MyTable t
WHERE = CONVERT(DATE, t.[DateColumn]) = CONVERT(DATE, @dateVar);

-- Quicker when there is no index on t.[DateColumn]
DECLARE @dateEnd datetime = DATEADD(DAY, 1, @dateVar);
SELECT t.[DateColumn] 
FROM MyTable t
WHERE t.[DateColumn] >= @dateVar AND 
      t.[DateColumn] < @dateEnd;

Also from that article: using BETWEEN, DATEDIFF or CONVERT(CHAR(8)... are all slower.

Converts the buffer's contents into a string by decoding the bytes using the named charset.

I will provide a detailed differences between Visual Studio and Visual Studio Code below.

If you really look at it the most obvious difference is that .NET has been split into two:

• .NET Core (Mac, Linux, and Windows)
• .NET Framework (Windows only)

All native user interface technologies (Windows Presentation Foundation, Windows Forms, etc.) are part of the framework, not the core.

The "Visual" in Visual Studio (from Visual Basic) was largely synonymous with visual UI (drag & drop WYSIWYG) design, so in that sense, Visual Studio Code is Visual Studio without the Visual!

The second most obvious difference is that Visual Studio tends to be oriented around projects & solutions.

Visual Studio Code:

• It's a lightweight source code editor which can be used to view, edit, run, and debug source code for applications.
• Simply it is Visual Studio without the Visual UI, majorly a superman’s text-editor.
• It is mainly oriented around files, not projects.
• It does not have any scaffolding support.
• It is a competitor of Sublime Text or Atom on Electron.
• It is based on the Electron framework, which is used to build cross platform desktop application using web technologies.
• It does not have support for Microsoft's version control system; Team Foundation Server.
• It has limited IntelliSense for Microsoft file types and similar features.
• It is mainly used by developers on a Mac who deal with client-side technologies (HTML, JavaScript, and CSS).

Visual Studio:

• As the name indicates, it is an IDE, and it contains all the features required for project development. Like code auto completion, debugger, database integration, server setup, configurations, and so on.
• It is a complete solution mostly used by and for .NET related developers. It includes everything from source control to bug tracker to deployment tools, etc. It has everything required to develop.
• It is widely used on .NET related projects (though you can use it for other things). The community version is free, but if you want to make most of it then it is not free.

• Visual Studio is aimed to be the world’s best IDE (integrated development environment), which provide full stack develop toolsets, including a powerful code completion component called IntelliSense, a debugger which can debug both source code and machine code, everything about ASP.NET development, and something about SQL development.

• In the latest version of Visual Studio, you can develop cross-platform application without leaving the IDE. And Visual Studio takes more than 8 GB disk space (according to the components you select).

• In brief, Visual Studio is an ultimate development environment, and it’s quite heavy.

Let the command you are trying to pass be

os.system('x')

then you covert it to a statement

t = os.system('x')

now the python will be waiting for the output from the commandline so that it could be assigned to the variable t.

Use this way so that result will not be displayed while running stored procedure.

The query:

SELECT a.strUserID FROM tblUsers a WHERE a.lngUserID = lngUserID LIMIT 1 INTO @strUserID;

You can use the root.configure(background='your colour') example:- import tkinter root=tkiner.Tk() root.configure(background='pink')

If you are still interested in a javascript api to select both date and time data, have a look at these projects which are forks of bootstrap datepicker:

• Bootstrap Datetime Picker 1

• Bootstrap Datetime Picker 2

The first fork is a big refactor on the parsing/formatting codebase and besides providing all views to select date/time using mouse/touch, it also has a mask option (by default) which lets the user to quickly type the date/time based on a pre-specified format.

Had similar issue but wanted to have center drawable with no text and no wrapped layouts. Solution was to create custom button and add one more drawable in addition to LEFT, RIGHT, TOP, BOTTOM. One can easily modify drawable placement and have it in desired position relative to text.

CenterDrawableButton.java

public class CenterDrawableButton extends Button {
    private Drawable mDrawableCenter;

    public CenterDrawableButton(Context context) {
        super(context);
        init(context, null);
    }

    public CenterDrawableButton(Context context, AttributeSet attrs) {
        super(context, attrs);
        init(context, attrs);
    }

    public CenterDrawableButton(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        init(context, attrs);
    }

    @TargetApi(Build.VERSION_CODES.LOLLIPOP)
    public CenterDrawableButton(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
        init(context, attrs);
    }


    private void init(Context context, AttributeSet attrs){
        //if (isInEditMode()) return;
        if(attrs!=null){
            TypedArray a = context.getTheme().obtainStyledAttributes(
                    attrs, R.styleable.CenterDrawableButton, 0, 0);

            try {
                setCenterDrawable(a.getDrawable(R.styleable.CenterDrawableButton_drawableCenter));

            } finally {
                a.recycle();
            }

        }
    }

    public void setCenterDrawable(int center) {
        if(center==0){
            setCenterDrawable(null);
        }else
        setCenterDrawable(getContext().getResources().getDrawable(center));
    }
    public void setCenterDrawable(@Nullable Drawable center) {
        int[] state;
        state = getDrawableState();
        if (center != null) {
            center.setState(state);
            center.setBounds(0, 0, center.getIntrinsicWidth(), center.getIntrinsicHeight());
            center.setCallback(this);
        }
        mDrawableCenter = center;
        invalidate();
        requestLayout();
    }
    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        if(mDrawableCenter!=null) {
            setMeasuredDimension(Math.max(getMeasuredWidth(), mDrawableCenter.getIntrinsicWidth()),
                    Math.max(getMeasuredHeight(), mDrawableCenter.getIntrinsicHeight()));
        }
    }
    @Override
    protected void drawableStateChanged() {
        super.drawableStateChanged();
        if (mDrawableCenter != null) {
            int[] state = getDrawableState();
            mDrawableCenter.setState(state);
            mDrawableCenter.setBounds(0, 0, mDrawableCenter.getIntrinsicWidth(),
                    mDrawableCenter.getIntrinsicHeight());
        }
        invalidate();
    }

    @Override
    protected void onDraw(@NonNull Canvas canvas) {
        super.onDraw(canvas);

        if (mDrawableCenter != null) {
            Rect rect = mDrawableCenter.getBounds();
            canvas.save();
            canvas.translate(getWidth() / 2 - rect.right / 2, getHeight() / 2 - rect.bottom / 2);
            mDrawableCenter.draw(canvas);
            canvas.restore();
        }
    }
}

attrs.xml

Built off the above but with dynamic creation and a vector image, not drawing.

function svgztruck() {
    tok = "{d path value}"
    return tok;
}

function buildsvg( eid ) {
    console.log("building");
    var zvg = "svg" + eid;
    var vvg = eval( zvg );
    var raw = vvg();

    var svg = document.getElementById( eid );
    svg.setAttributeNS(null,"d", raw );
    svg.setAttributeNS(null,"fill","green");
    svg.setAttributeNS(null,"onlick", eid + ".style.fill=#FF0000");
    return;
}

You could call with:

<img src="" onerror="buildscript">

Now you can add colors by sub element and manipulate all elements of the dom directly. It is important to implement your viewbox and height width first on the svg html, not done in the example above.

There is no need to make your code 10 pages when it could be one... but who am I to argue. Better use PHP while your at it.

The inner element that svg builds on is a simple <svg lamencoding id=parenteid><path id=eid><svg> with nothing else.

I faced similar issue. My controller name was documents. It manages uploaded documents. It was working fine and started showing this error after completion of code. The mistake I did is - Created a folder 'Documents' to save the uploaded files. So controller name and folder name were same - which made the issue.

Today things have changed a little.

Now we avoid use ProgressDialog to show spinning progress:

If you want to put in your app a spinning progress you should use an Activity indicators:

http://developer.android.com/design/building-blocks/progress.html#activity

Thank for the answers,

The border is removed for Internet Explorer, but this there for Firefox.

So, I added this class to the img:

.clearBorder{border:none;}

And it worked!

Can JAX-RS do Asynchronous Request like JAX-WS?

1) I don't know if the JAX-RS API includes a specific mechanism for asynchronous requests, but this answer could still change based on the client implementation you use.

Can JAX-RS access a web service that is not running on the Java platform, and vice versa?

2) I can't think of any reason it wouldn't be able to.

What does it mean by "REST is particularly useful for limited-profile devices, such as PDAs and mobile phones"?

3) REST based architectures typically will use a lightweight data format, like JSON, to send data back and forth. This is in contrast to JAX-WS which uses XML. I don't see XML by itself so significantly heavier than JSON (which some people may argue), but with JAX-WS it's how much XML is used that ends up making REST with JSON the lighter option.

What does it mean by "JAX-RS do not require XML messages or WSDL service–API definitions?

4) As stated in 3, REST architectures often use JSON to send and receive data. JAX-WS uses XML. It's not that JSON is so significantly smaller than XML by itself. It's mostly that JAX-WS specification includes lots overhead in how it communicates.

On the point about WSDL and API definitions, REST will more frequently use the URI structure and HTTP commands to define the API rather than message types, as is done in the JAX-WS. This means that you don't need to publish a WSDL document so that other users of your service can know how to talk to your service. With REST you will still need to provide some documentation to other users about how the REST service is organized and what data and HTTP commands need to be sent.

You don't actually need to run a command from an xterm session, you can run it directly:

String[] arguments = new String[] {"/path/to/executable", "arg0", "arg1", "etc"};
Process proc = new ProcessBuilder(arguments).start();

If the process responds interactively to the input stream, and you want to inject values, then do what you did before:

OutputStream out = proc.getOutputStream();  
out.write("command\n");  
out.flush();

Don't forget the '\n' at the end though as most apps will use it to identify the end of a single command's input.

It might be not direct solution, but I've created a lib that allows you to use 3 fingers touch instead of shake to open dev menu, when in development mode

https://github.com/pie6k/react-native-dev-menu-on-touch

You only have to wrap your app inside:

import DevMenuOnTouch from 'react-native-dev-menu-on-touch'; // or: import { DevMenuOnTouch } from 'react-native-dev-menu-on-touch'

class YourRootApp extends Component {
  render() {
    return (
      <DevMenuOnTouch>
        <YourApp />
      </DevMenuOnTouch>
    );
  }
}

It's really useful when you have to debug on real device and you have co-workers sitting next to you.

To capture several parameters using the same name, I modified the while loop in Tomalak's method like this:

  while (match = re.exec(url)) {
    var pName = decode(match[1]);
    var pValue = decode(match[2]);
    params[pName] ? params[pName].push(pValue) : params[pName] = [pValue];
  }

input: ?firstname=george&lastname=bush&firstname=bill&lastname=clinton

returns: {firstname : ["george", "bill"], lastname : ["bush", "clinton"]}

With the introduction of Razor in ASP.net MVC, the best way to write HTML in C# is with the Razor Engine.

string templatePath = $@"{Directory.GetCurrentDirectory()}\EmailTemplates"; 

IRazorLightEngine engine = EngineFactory.CreatePhysical(templatePath); 

var model = new Notification 
{ 
       Name = "Jone", 
       Title = "Test Email", 
       Content = "This is a test" 
}; 

string result = engine.Parse("template.cshtml", model); 

Template:

<h2>Dear @Model.Name, you have a notification.</h2> 

<h1>@Model.Title</h1> 
<p>@Model.Content</p> 

<p>Date:@DateTime.Now</p> 

For a complete sample, see here

the best way (for me) to make it it's the next infrastructure:

<form method="POST">
<input type="submit" formaction="default_url_when_press_enter" style="visibility: hidden; display: none;">
<!-- all your inputs -->
<input><input><input>
<!-- all your inputs -->
<button formaction="action1">Action1</button>
<button formaction="action2">Action2</button>
<input type="submit" value="Default Action">
</form>

with this structure you will send with enter a direction and the infinite possibilities for the rest of buttons.

Controller-

var app= angular.module('app', []);

app.controller('TestController', function($scope) {
    this.arrayText = [{text:'Hello',},{text: 'world'}];

    this.addText = function(text) {

      if(text) {
        var obj = {
          text: text
        };
          this.arrayText.push(obj);
          this.myText = '';
          console.log(this.arrayText);
        }
      } 
 });

HTML

<form ng-controller="TestController as testCtrl" ng-submit="testCtrl.addText(testCtrl.myText)">
        <input type="text" ng-model="testCtrl.myText" value="Lets go">
        <button type="submit">Add</button>
        <div ng-repeat="item in testCtrl.arrayText">
            <span>{{item}}</span>
        </div>
</form>

Use the ampersand just like you would from the shell.

#!/usr/bin/bash
function_to_fork() {
   ...

function_to_fork &
# ... execution continues in parent process ...

You could use the following query:

SELECT  table1.id 
FROM    table1 
        LEFT JOIN table2 
            ON table1.id IN (table2.user_one, table2.user_two)
WHERE   table2.user_one IS NULL;

Although, depending on your indexes on table2 you may find that two joins performs better:

SELECT  table1.id 
FROM    table1 
        LEFT JOIN table2 AS t1
            ON table1.id = t1.user_one
        LEFT JOIN table2 AS t2
            ON table1.id = t2.user_two
WHERE   t1.user_one IS NULL
AND     t2.user_two IS NULL;

You can also watch the output like this:

final Process p = Runtime.getRuntime().exec("java -jar map.jar time.rel test.txt debug");

new Thread(new Runnable() {
    public void run() {
        BufferedReader input = new BufferedReader(new InputStreamReader(p.getInputStream()));
        String line = null;

        try {
            while ((line = input.readLine()) != null)
                System.out.println(line);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}).start();

p.waitFor();

And don't forget, if you are running a windows command, you need to put cmd /c in front of your command.

EDIT: And for bonus points, you can also use ProcessBuilder to pass input to a program:

String[] command = new String[] {
        "choice",
        "/C",
        "YN",
        "/M",
        "\"Press Y if you're cool\""
};
String inputLine = "Y";

ProcessBuilder pb = new ProcessBuilder(command);
pb.redirectErrorStream(true);
Process p = pb.start();
BufferedReader reader = new BufferedReader(new InputStreamReader(p.getInputStream()));
BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(p.getOutputStream()));

writer.write(inputLine);
writer.newLine();
writer.close();

String line;

while ((line = reader.readLine()) != null) {
    System.out.println(line);
}

This will run the windows command choice /C YN /M "Press Y if you're cool" and respond with a Y. So, the output will be:

Press Y if you're cool [Y,N]?Y

To the best of my knowledge, you need to put your entire Java app in UTC timezone (so that Hibernate will store dates in UTC), and you'll need to convert to whatever timezone desired when you display stuff (at least we do it this way).

At startup, we do:

TimeZone.setDefault(TimeZone.getTimeZone("Etc/UTC"));

And set the desired timezone to the DateFormat:

fmt.setTimeZone(TimeZone.getTimeZone("Europe/Budapest"))

Had a similar issue. But it is important to understand the root cause and it may vary for different use cases.

Scenario 1
You are trying to decrypt a value which was not encoded correctly in the first place.

byte[] encryptedBytes = Base64.decodeBase64(encryptedBase64String);

If the String is misconfigured for certain reason or has not been encoded correctly, you would see the error " Input length must be multiple of 16 when decrypting with padded cipher"

Scenario 2
Now if by any chance you are using this encoded string in url (trying to pass in the base64Encoded value in url, it will fail. You should do URLEncoding and then pass in the token, it will work.

Scenario 3
When integrating with one of the vendors, we found that we had to do encryption of Base64 using URLEncoder but then we need not decode it because it was done internally by the Vendor

One small point to Andy Hayden's solution – it doesn't work (anymore?) because np.nan == np.nan yields False, so the replace function doesn't actually do anything.

What worked for me was this:

df['b'] = df['b'].apply(lambda x: x if not np.isnan(x) else -1)

(At least that's the behavior for Pandas 0.19.2. Sorry to add it as a different answer, I do not have enough reputation to comment.)

In Eclipse, go to Help -> Install New Software -> Add -> Name: any name like egit; Location: http://download.eclipse.org/egit/updates -> Okay. Now Search for egit in Work with and select all the check boxes and press Next till finish.

File -> Import -> search Git and select "Projects from Git" -> Clone URI. In the URI, paste the HTTPS URL of the repository (the one with .git extension). -> Next ->It will show all the branches "Next" -> Local Destination "Next" -> "Import as a general project" -> Next till finish.

The Excel number for a modern date is most easily calculated as the number of days since 12/30/1899 on the Gregorian calendar.

Excel treats the mythical date 01/00/1900 (i.e., 12/31/1899) as corresponding to 0, and incorrectly treats year 1900 as a leap year. So for dates before 03/01/1900, the Excel number is effectively the number of days after 12/31/1899.

However, Excel will not format any number below 0 (-1 gives you ##########) and so this only matters for "01/00/1900" to 02/28/1900, making it easier to just use the 12/30/1899 date as a base.

A complete function in DB2 SQL that accounts for the leap year 1900 error:

SELECT
   DAYS(INPUT_DATE)                 
   - DAYS(DATE('1899-12-30'))
   - CASE                       
        WHEN INPUT_DATE < DATE('1900-03-01')  
           THEN 1               
           ELSE 0               
     END

If you need to support other formats as well or just need good performance, you can use this WebAssembly library

it's promised based, it uses WebWorkers for threading and API is actually simple ES module

I had a similar problem and it was related to the version. In a python terminal check:

>> import xlrd
>> xlrd.__VERSION__

If you have '0.9.0' you can open almost all files. If you have '0.6.0' which was what I found on Ubuntu, you may have problems with newest Excel files. You can download the latest version of xlrd using the Distutils standard.

Running the command prompt or Powershell ISE as an administrator fixed this for me.

Use

datatable.select("col1='test'","col1 ASC")

Then before binding your data to the grid or repeater etc, use this

datatable.defaultview.sort()

That will solve your problem.

Another way to get this error, is if you have duplicate or conflicting ~/.ssh/* entries. First check what is on your ssh key-chain with:

$ ssh-add -l
2048 SHA256:<hash1> [email protected] (RSA)
2048 SHA256:<hash2> [email protected] (RSA)
2048 SHA256:<hash3> [email protected] (RSA)

As you can see there are two emails which are the same, and easy for you to get confused. Then check your config file:

$ cat ~/.ssh/config

# GitHub: [email protected]
Host github_ex
 HostName github.com
 PreferredAuthentications publickey
 IdentityFile ~/.ssh/github_ex

# GitHub: [email protected]
Host github
 HostName github.com
 PreferredAuthentications publickey
 IdentityFile ~/.ssh/github

# Bitbucket: [email protected]
Host bitbucket
 HostName bitbucket.org
 PreferredAuthentications publickey
 IdentityFile ~/.ssh/bitbuc

Here you see that you have two different email accounts to github but same HostName. Someone is bound to get confused, including your git.

To resolve, manually remove (after copying) the (default) files:

cd ~/.ssh
rm id_rsa
rm id_rsa.pub

Now copy back the one you want to use, for example Host github:

cp -a github id_rsa
cp -a github.pub id_rsa.pub

Then try again.

For some reason, removing keys with ssh-add -d id_rsa didn't work as expected, as it seem that key-chain is cached.

TGrid is another option that people don't usually find in a google search. If the other grids you find don't suit your needs, you can give it a try, its free

You can need to pass in the string 'int64':

>>> import pandas as pd
>>> df = pd.DataFrame({'a': [1.0, 2.0]})  # some test dataframe

>>> df['a'].astype('int64')
0    1
1    2
Name: a, dtype: int64

There are some alternative ways to specify 64-bit integers:

>>> df['a'].astype('i8')      # integer with 8 bytes (64 bit)
0    1
1    2
Name: a, dtype: int64

>>> import numpy as np
>>> df['a'].astype(np.int64)  # native numpy 64 bit integer
0    1
1    2
Name: a, dtype: int64

Or use np.int64 directly on your column (but it returns a numpy.array):

>>> np.int64(df['a'])
array([1, 2], dtype=int64)

var start = +new Date();
var counter = 0;
for(var i = 1; i < LIMIT; i++){
    ++counter;
    db.users.save({id : i, name : "MongoUser [" + i + "]"}, function(err, saved) {
          if( err || !saved ) console.log("Error");
          else console.log("Saved");
          if (--counter === 0) 
          {
              var end = +new Date();
              console.log("all users saved in " + (end-start) + " milliseconds");
          }
    });
}

Swift Version --> Remove the object from your data array before you call

func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
    if editingStyle == .delete {
        print("Deleted")

        currentCart.remove(at: indexPath.row) //Remove element from your array 
        self.tableView.deleteRows(at: [indexPath], with: .automatic)
    }
}

Just saying, this is also the value (kind of...) that is returned from php upon:

<?php var_dump(urlencode(PHP_EOL)); ?> 
    // Prints: string '%0D%0A' (length=6)-- used in 5.4.24 at least

You need to set the parent element to 100% as well

html, body {
    height: 100%;
}

Demo (Changed the background for demo purpose)

Also, when you want to cover entire screen, seems like you want to dim, so in this case, you need to use position: fixed;

#dimScreen {
    width: 100%;
    height: 100%;
    background:rgba(255,255,255,0.5); 
    position: fixed;
    top: 0;
    left: 0;
    z-index: 100; /* Just to keep it at the very top */
}

If that's the case, than you don't need html, body {height: 100%;}

Demo 2

git branch --set-upstream <<origin/branch>> is officially not supported anymore and is replaced by git branch --set-upstream-to <<origin/branch>>

There's at least 7 different ways to test if a number is odd or even. But, if you read through these benchmarks, you'll find that as TGH mentioned above, the modulus operation is the fastest:

if (x % 2 == 0)
               //even number
        else
               //odd number

Here are a few other methods (from the website) :

//bitwise operation
if ((x & 1) == 0)
       //even number
else

Here is Oliver Steele's image of how all it all fits together:

If there is sufficient interest, I suppose I could update the image to add git clone and git merge...

More flexible than select max() is:

select distinct first_row(column_x) over (order by column_y,column_z,...) from Table_A

If you are using Python 3, you can use urllib.parse

url = """example.com?title=%D0%BF%D1%80%D0%B0%D0%B2%D0%BE%D0%B2%D0%B0%D1%8F+%D0%B7%D0%B0%D1%89%D0%B8%D1%82%D0%B0"""

import urllib.parse
urllib.parse.unquote(url)

gives:

'example.com?title=????????+??????'
