There is a library that can help with Unicode issues called ftfy. Has made my life easier.

Example 1

import ftfy
print(ftfy.fix_text('ünicode'))

output -->
ünicode

Example 2 - UTF-8

import ftfy
print(ftfy.fix_text('\xe2\x80\xa2'))

output -->
•

Example 3 - Unicode code point

import ftfy
print(ftfy.fix_text(u'\u2026'))

output -->

Assuming that you do not want to change orig, you can either do a copy and update like the other answers, or you can create a new dictionary in one step by passing all items from both dictionaries into the dict constructor:

from itertools import chain
dest = dict(chain(orig.items(), extra.items()))

Or without itertools:

dest = dict(list(orig.items()) + list(extra.items()))

Note that you only need to pass the result of items() into list() on Python 3, on 2.x dict.items() already returns a list so you can just do dict(orig.items() + extra.items()).

As a more general use case, say you have a larger list of dicts that you want to combine into a single dict, you could do something like this:

from itertools import chain
dest = dict(chain.from_iterable(map(dict.items, list_of_dicts)))

Unfortunately , JSONArray doesn't support foreach statements, like:

for(JSONObject someObj : someJsonArray) {_x000D_
    // do something about someObj_x000D_
    ...._x000D_
    ...._x000D_
}

I suggest using Object.prototype.constructor.name:

Object.defineProperty(Object.prototype, "getClass", {
    value: function() {
      return this.constructor.name;
    }
});

var x = new DOMParser();
console.log(x.getClass()); // `DOMParser'

var y = new Error("");
console.log(y.getClass()); // `Error'

You may create a new list with an input of a previous list like so:

List one = new ArrayList()
//... add data, sort, etc
List two = new ArrayList(one);

This will allow you to modify the order or what elemtents are contained independent of the first list.

Keep in mind that the two lists will contain the same objects though, so if you modify an object in List two, the same object will be modified in list one.

example:

MyObject value1 = one.get(0);
MyObject value2 = two.get(0);
value1 == value2 //true
value1.setName("hello");
value2.getName(); //returns "hello"

Edit

To avoid this you need a deep copy of each element in the list like so:

List<Torero> one = new ArrayList<Torero>();
//add elements

List<Torero> two = new Arraylist<Torero>();
for(Torero t : one){
    Torero copy = deepCopy(t);
    two.add(copy);
}

with copy like the following:

public Torero deepCopy(Torero input){
    Torero copy = new Torero();
    copy.setValue(input.getValue());//.. copy primitives, deep copy objects again

    return copy;
}

If your string is going in a UIView (e.g a UILabel), you also need to set the number of lines to 0

myView.numberOfLines=0;

Also, you can do it with css selectors:

form#myform input[type='submit']

space beween elements in css elector means searching input[type='submit'] that elements at any depth of parent form#myform element

Alternatively you can convert your object into a dataframe first:

df = pd.DataFrame(obj)

and then save this dataframe in a json file:

df.to_json(path_or_buf='df.json')

Hope this helps

In case of array like

result = [ '2015',  '2014',  '2013',  '2011' ],

it gets tricky if you are using escape sequence like:

result = [ \'2015\',  \'2014\',  \'2013\',  \'2011\' ].

Instead, good way to do it is to wrap the array with single quotes as follows:

result = "'"+result+"'";

Finally after a lot of tests, I think the most convenient and efficient way to preset is:

var presetValue = "black";
$("input[name=correctAnswer]").filter("[value=" + presetValue + "]").prop("checked",true);
$("input[name=correctAnswer]").button( "refresh" );//JQuery UI only

The refresh is required with the JQueryUI object.

Retrieving the value is easy :

alert($('input[name=correctAnswer]:checked').val())

Tested with JQuery 1.6.1, JQuery UI 1.8.

This gives a pretty good overview over the current options. Some of which are named in other answers. Jython is not usable until they decide to implement Python 3.x and many of the other projects are coming form the python side and want to access java. But there are a few options still, to name something which has not been named yet: gRPC

you should try this

~/Views/Shared/parts/UMFview.ascx

place the ~/Views/ before your code

Use the isSelected method.

You can also use an ItemListener so you'll be notified when it's checked or unchecked.

The Inversion of Control (IoC) and Dependency Injection (DI) patterns are all about removing dependencies from your code.

For example, say your application has a text editor component and you want to provide spell checking. Your standard code would look something like this:

public class TextEditor {

    private SpellChecker checker;

    public TextEditor() {
        this.checker = new SpellChecker();
    }
}

What we've done here creates a dependency between the TextEditor and the SpellChecker. In an IoC scenario we would instead do something like this:

public class TextEditor {

    private IocSpellChecker checker;

    public TextEditor(IocSpellChecker checker) {
        this.checker = checker;
    }
}

In the first code example we are instantiating SpellChecker (this.checker = new SpellChecker();), which means the TextEditor class directly depends on the SpellChecker class.

In the second code example we are creating an abstraction by having the SpellChecker dependency class in TextEditor's constructor signature (not initializing dependency in class). This allows us to call the dependency then pass it to the TextEditor class like so:

SpellChecker sc = new SpellChecker(); // dependency
TextEditor textEditor = new TextEditor(sc);

Now the client creating the TextEditor class has control over which SpellChecker implementation to use because we're injecting the dependency into the TextEditor signature.

The CSS uses only the data in the DOM tree, which has little to do with how the renderer decides what to do with elements with missing attributes.

So either let the CSS reflect the HTML

input:not([type]), input[type="text"]
{
background:red;
}

or make the HTML explicit.

<input name='t1' type='text'/> /* Is Not Red */

If it didn't do that, you'd never be able to distinguish between

element { ...properties... }

and

element[attr] { ...properties... }

because all attributes would always be defined on all elements. (For example, table always has a border attribute, with 0 for a default.)

If you're seeing this error message when attempting to connect using SSMS, add TrustServerCertificate=True to the Additional Connection Parameters.

DateTime dateValue;
CultureInfo culture = CultureInfo.CurrentCulture;
DateTimeStyles styles = DateTimeStyles.None;
DateTime.TryParse(datetimestring,culture, styles, out dateValue);

The 1337 set of comics from xkcd, starting with:

new Date(year,month,day,0,0,0,0) is local time (as input) new Date(year,month,day) is UTC

I was using a function to attain YYYY-MM-DD format to be compatible on iOS web, but that is also UTC when used in comparisons (not chained by getFullYear or similar) I've found it is best to use only the above with strong (hours,minutes,seconds,milliseconds) building a calendar, calculating with a Date objects and local references

export const zeroPad = (num) => {
  var res = "0";
  if (String(num).length === 1) {
    res = `0${num}`;
  } else {
    res = num;
  }
  return res;
};

You said:

I want them to always come out as Tanzanian time and not in the local times that various collaborator are in.

If this is the case, then you should not use UTC. All you need to do is to use a DATETIME type in MySQL instead of a TIMESTAMP type.

From the MySQL documentation:

MySQL converts TIMESTAMP values from the current time zone to UTC for storage, and back from UTC to the current time zone for retrieval. (This does not occur for other types such as DATETIME.)

If you are already using a DATETIME type, then you must be not setting it by the local time to begin with. You'll need to focus less on the database, and more on your application code - which you didn't show here. The problem, and the solution, will vary drastically depending on language, so be sure to tag the question with the appropriate language of your application code.

First off, are you setting your desired JRE or your desired JDK?

Even if your Eclipse is set up properly, there might be a wacky project-specific setting somewhere. You can open up a context menu on a given Java project in the Project Explorer and select Properties > Java Compiler to check on that.

If none of that helps, leave a comment and I'll take another look.

The fact that your method does not use the self argument (which is a reference to the instance that the method is attached to) doesn't mean you can leave it out. It always has to be there, because Python is always going to try to pass it in.

Remove the date() part

SELECT name, datum 
FROM tasks 
WHERE datum >= NOW()

and if you use a specific date, don't forget the quotes around it and use the proper format with :

SELECT name, datum 
FROM tasks 
WHERE datum >= '2014-05-18 15:00:00'

Keep in mind, that 'Country/Zone' is not working sometimes... This issue is not OS, MySQL version and hardware dependent - I've met it since FreeBSD 4 and Slackware Linux in year 2003 till today. MySQL from version 3 till latest source trunk. It is ODD, but it DOES happens. For example:

root@Ubuntu# ls -la /usr/share/zoneinfo/US
total 8

drwxr-xr-x  2 root root 4096 Apr 10  2013 .
drwxr-xr-x 22 root root 4096 Apr 10  2013 ..
lrwxrwxrwx  1 root root   18 Jul  8 22:33 Alaska -> ../SystemV/YST9YDT
lrwxrwxrwx  1 root root   21 Jul  8 22:33 Aleutian -> ../posix/America/Adak
lrwxrwxrwx  1 root root   15 Jul  8 22:33 Arizona -> ../SystemV/MST7

lrwxrwxrwx  1 root root   19 Jul  8 22:33 Hawaii -> ../Pacific/Honolulu
lrwxrwxrwx  1 root root   24 Jul  8 22:33 Indiana-Starke -> ../posix/America/Knox_IN
lrwxrwxrwx  1 root root   24 Jul  8 22:33 Michigan -> ../posix/America/Detroit
lrwxrwxrwx  1 root root   18 Jul  8 22:33 Mountain -> ../SystemV/MST7MDT

lrwxrwxrwx  1 root root   20 Jul  8 22:33 Samoa -> ../Pacific/Pago_Pago
root@Ubuntu#

And a statement like that is supposed to work:

SET time_zone='US/Eastern';

But you have this problem:

Error Code: 1298. Unknown or incorrect time zone: 'EUS/Eastern'

Take a look at the subfolder in your zone information directory, and see the ACTUAL filename for symlink, in this case it's EST5EDT. Then try this statement instead:

SET time_zone='EST5EDT';

And it's actually working as it is supposed to! :) Keep this trick in mind; I haven't seen it to be documented in MySQL manuals and official documentation. But reading the corresponding documentation is must-do thing: MySQL 5.5 timezone official documentation - and don't forget to load timezone data into your server just like that (run as root user!):

mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root mysql

Trick number one - it must be done exactly under MySQL root user. It can fail or produce non-working result even from the user that has full access to a MySQL database - I saw the glitch myself.

If your shell/prompt complains that it cannot find the command, it likely means that you installed Anaconda without adding it to the PATH environment variable.

If that's the case find and open the Anaconda Prompt and do it from there.

Alternatively reinstall Anaconda choosing to add it to the PATH. Or add the variable manually.

Anaconda Prompt should be available in your Start Menu (Win) or Applications Menu (macos)

Already mentioned previously by swilliams, but with an example below (Javascript):

// Function wrapping inner for loop
function CriteriaMatch(record, criteria) {
  for (var k in criteria) {
    if (!(k in record))
      return false;

    if (record[k] != criteria[k])
      return false;
  }

  return true;
}

// Outer for loop implementing continue if inner for loop returns false
var result = [];

for (var i = 0; i < _table.length; i++) {
  var r = _table[i];

  if (!CriteriaMatch(r[i], criteria))
    continue;

  result.add(r);
}

It varies from assembler to assembler. Most machines offer registers, which have symbolic names like R1, or EAX (the Intel x86), and have instruction names like "CMP" for compare. And for a compare instruction, you need another operand, sometimes a register, sometimes a literal. Often assemblers allow comments to the right of instruction.

An instruction line looks like:

<opcode>   <register> <operand>   ; comment

Your assembler may vary somewhat.

For the Microsoft X86 assembler, you can write:

CMP EAX, 23 ; compare register EAX with the constant 23

or

CMP EAX, XYZ ; compare register EAX with contents of memory location named XYZ

Often one can write complex "expressions" in the operand field that enable the instruction, if it has the capability, to address memory in variety of ways. But I think this answers your question.

Update (using renderer):

Note that the original Renderer service has now been deprecated in favor of Renderer2

as on Renderer2 official doc.

Furthermore, as pointed out by @GünterZöchbauer:

Actually using ElementRef is just fine. Also using ElementRef.nativeElement with Renderer2 is fine. What is discouraged is accessing properties of ElementRef.nativeElement.xxx directly.

You can achieve this by using elementRef as well as by ViewChild. however it's not recommendable to use elementRef due to:

• security issue
• tight coupling

as pointed out by official ng2 documentation.

1. Using elementRef (Direct Access):

export class MyComponent {    
constructor (private _elementRef : ElementRef) {
 this._elementRef.nativeElement.querySelector('textarea').focus();
 }
}

2. Using ViewChild (better approach):

<textarea  #tasknote name="tasknote" [(ngModel)]="taskNote" placeholder="{{ notePlaceholder }}" 
style="background-color: pink" (blur)="updateNote() ; noteEditMode = false " (click)="noteEditMode = false"> {{ todo.note }} </textarea> // <-- changes id to local var


export class MyComponent implements AfterViewInit {
  @ViewChild('tasknote') input: ElementRef;

   ngAfterViewInit() {
    this.input.nativeElement.focus();

  }
}

3. Using renderer:

export class MyComponent implements AfterViewInit {
      @ViewChild('tasknote') input: ElementRef;
         constructor(private renderer: Renderer2){           
          }

       ngAfterViewInit() {
       //using selectRootElement instead of depreaced invokeElementMethod
       this.renderer.selectRootElement(this.input["nativeElement"]).focus();
      }

    }

Just as there are printer drivers that do not connect to a printer at all but rather write to a PDF file, analogously there are virtual audio drivers available that do not connect to a physical microphone at all but can pipe input from other sources such as files or other programs.

I hope I'm not breaking any rules by recommending free/donation software, but VB-Audio Virtual Cable should let you create a pair of virtual input and output audio devices. Then you could play an MP3 into the virtual output device and then set the virtual input device as your "microphone". In theory I think that should work.

If all else fails, you could always roll your own virtual audio driver. Microsoft provides some sample code but unfortunately it is not applicable to the older Windows XP audio model. There is probably sample code available for XP too.

My problem was when my fellow developer added a pod in the project and then i pull the project using github then the error occurred. I ran pod install and it updated the pods with new library which was added by my fellow developer. hope it helps.

I use launch4j

ANT Command:

<target name="jar" depends="compile, buildDLLs, copy">
    <jar basedir="${java.bin.dir}" destfile="${build.dir}/Project.jar" manifest="META-INF/MANIFEST.MF" />
</target>

<target name="exe" depends="jar">
    <exec executable="cmd" dir="${launch4j.home}">
        <arg line="/c launch4jc.exe ${basedir}/${launch4j.dir}/L4J_ProjectConfig.xml" />
    </exec>
</target>

An alternative is to use String.format:

double[] arr = { 23.59004,
    35.7,
    3.0,
    9
};

for ( double dub : arr ) {
  System.out.println( String.format( "%.2f", dub ) );
}

output:

23.59
35.70
3.00
9.00

You could also use System.out.format (same method signature), or create a java.util.Formatter which works in the same way.

As MrFancypants mentioned in the comments, if you are using Jupyter (which you should, since it currently supersedes the older IPython Notebook project), things are a little different. For one, there are no profiles any more.

After installing Jupyter, first check your ~/.jupyter folder to see its content. If no config files were migrated from the default IPython profile (as they weren't in my case), create a new one for Jupyter Notebook:

jupyter notebook --generate-config

This generates ~/.jupyter/jupyter_notebook_config.py file with some helpfully commented possible options. To set the default directory add:

c.NotebookApp.notebook_dir = u'/absolute/path/to/notebook/directory'

As I switch between Linux and OS X, I wanted to use a path relative to my home folder (as they differ – /Users/username and /home/username), so I set something like:

import os
c.NotebookApp.notebook_dir = os.path.expanduser('~/Dropbox/dev/notebook')

Now, whenever I run jupyter notebook, it opens my desired notebook folder. I also version the whole ~/.jupyter folder in my dotfiles repository that I deploy to every new work machine.

As an aside, you can still use the --notebook-dir command line option, so maybe a simple alias would suit your needs better.

jupyter notebook --notebook-dir=/absolute/path/to/notebook/directory

Flutter provides a command to update the Android SDK path:

flutter config --android-sdk < path to your sdk >

OR

If you are facing this issue --> sdk file is not found in android-sdk\build-tools\28.0.3\aapt.

You may have probably not installed build tools for this Api level, Which can be installed through this link https://androidsdkmanager.azurewebsites.net/Buildtools

Maintain a list of nodes you can travel to, sorted by the distance from your start node. In the beginning only your start node will be in the list.

While you haven't reached your destination: Visit the node closest to the start node, this will be the first node in your sorted list. When you visit a node, add all its neighboring nodes to your list except the ones you have already visited. Repeat!

Slightly more elegant dict comprehension:

foodict = {k: v for k, v in mydict.items() if k.startswith('foo')}

The cleanest solution may be to use the "string-stream" package, which converts a stream to a string with a promise.

const streamString = require('stream-string')

streamString(myStream).then(string_variable => {
    // myStream was converted to a string, and that string is stored in string_variable
    console.log(string_variable)

}).catch(err => {
     // myStream emitted an error event (err), so the promise from stream-string was rejected
    throw err
})

The shiny package provides the convenient functions validate() and need() for checking that variables are both available and valid. need() evaluates an expression. If the expression is not valid, then an error message is returned. If the expression is valid, NULL is returned. One can use this to check if a variable is valid. See ?need for more information.

I suggest defining a function like this:

is.valid <- function(x) {
  require(shiny)
  is.null(need(x, message = FALSE))  
}

This function is.valid() will return FALSE if x is FALSE, NULL, NA, NaN, an empty string "", an empty atomic vector, a vector containing only missing values, a logical vector containing only FALSE, or an object of class try-error. In all other cases, it returns TRUE.

That means, need() (and is.valid()) covers a really broad range of failure cases. Instead of writing:

if (!is.null(x) && !is.na(x) && !is.nan(x)) {
  ...
}

one can write simply:

if (is.valid(x)) {
  ...
}

With the check for class try-error, it can even be used in conjunction with a try() block to silently catch errors: (see https://csgillespie.github.io/efficientR/programming.html#communicating-with-the-user)

bad = try(1 + "1", silent = TRUE)
if (is.valid(bad)) {
  ...
}

The defer attribute is only for external scripts (should only be used if the src attribute is present).

Button click event only.

        <script language="javascript" type="text/javascript">
            $(document).ready(function () {
                $("#btnext").click(function () {

One 'elegant' solution would be to use full text search: http://www.postgresql.org/docs/9.0/interactive/textsearch.html. Then you would use full text search queries.

Not that I recommend placing JavaScript directly into HTML, but this works in modern browsers (not IE11) to disable all submit buttons after a form submits:

<form onsubmit="this.querySelectorAll('[type=submit]').forEach(b => b.disabled = true)">

Some Linux distributions don't use the gdb style debugging symbols. (IIRC they prefer dwarf2.)

In general, gcc and gdb will be in sync as to what kind of debugging symbols they use, and forcing a particular style will just cause problems; unless you know that you need something else, use just -g.

This error sometimes occurs in a situation like this:

#ifndef NAN
#include <stdlib.h>
#define NAN (strtod("NAN",NULL))
#endif

static void init_random(uint32_t initseed=0)
{
    if (initseed==0)
    {
        struct timeval tv;
        gettimeofday(&tv, NULL);
        seed=(uint32_t) (4223517*getpid()*tv.tv_sec*tv.tv_usec);
    }
    else
        seed=initseed;
#if !defined(CYGWIN) && !defined(__INTERIX)
    //seed=42
    //SG_SPRINT("initializing random number generator with %d (seed size %d)\n", seed, RNG_SEED_SIZE)
    initstate(seed, CMath::rand_state, RNG_SEED_SIZE);
#endif
}

If the following code lines not run in the run-time:

#ifndef NAN
#include <stdlib.h>
#define NAN (strtod("NAN",NULL))
#endif

you will face with an error in your code like something as follows; because initstate is placed in the stdlib.h file and it's not included:

Known Issues with the above function:

1) Does not support "scientific notation" (1.23E-123), fiscal (leading $ or other) or "Trailing f" (C++ style floats) or "trailing currency" (USD, GBP etc)

2) False positive on string filenames that match a decimal: Please note that for example "10.0" as a filename cannot be distinguished from the decimal, so if you are attempting to detect a type from a string alone, and a filename matches a decimal name and has no path included, it will be impossible to discern.

If you have a MacOS computer (mine is MOJAVE 10.14.2), just add these lines to the end of your ~/.bash_profile file:

export ANGULAR=~/.nvm/versions/node/v10.8.0/bin/ng
export PATH=$ANGULAR:$PATH

Notice that v10.8.0 is the version of my installed Node.js. To get which version is yours, run this:

node --version

When done, reload it via your terminal/bash:

cd ~
source .bash_profile

After doing these steps you should be able to run your ng binary file.

You can't do that if USER is defined as a quoted string.

But you can do that if USER is just JACK or QUEEN or Joker or whatever.

There are two tricks to use:

1. Token-splicing, where you combine an identifier with another identifier by just concatenating their characters. This allows you to compare against JACK without having to #define JACK to something
2. variadic macro expansion, which allows you to handle macros with variable numbers of arguments. This allows you to expand specific identifiers into varying numbers of commas, which will become your string comparison.

So let's start out with:

#define JACK_QUEEN_OTHER(u) EXPANSION1(ReSeRvEd_, u, 1, 2, 3)

Now, if I write JACK_QUEEN_OTHER(USER), and USER is JACK, the preprocessor turns that into EXPANSION1(ReSeRvEd_, JACK, 1, 2, 3)

Step two is concatenation:

#define EXPANSION1(a, b, c, d, e) EXPANSION2(a##b, c, d, e)

Now JACK_QUEEN_OTHER(USER) becomes EXPANSION2(ReSeRvEd_JACK, 1, 2, 3)

This gives the opportunity to add a number of commas according to whether or not a string matches:

#define ReSeRvEd_JACK x,x,x
#define ReSeRvEd_QUEEN x,x

If USER is JACK, JACK_QUEEN_OTHER(USER) becomes EXPANSION2(x,x,x, 1, 2, 3)

If USER is QUEEN, JACK_QUEEN_OTHER(USER) becomes EXPANSION2(x,x, 1, 2, 3)

If USER is other, JACK_QUEEN_OTHER(USER) becomes EXPANSION2(ReSeRvEd_other, 1, 2, 3)

At this point, something critical has happened: the fourth argument to the EXPANSION2 macro is either 1, 2, or 3, depending on whether the original argument passed was jack, queen, or anything else. So all we have to do is pick it out. For long-winded reasons, we'll need two macros for the last step; they'll be EXPANSION2 and EXPANSION3, even though one seems unnecessary.

Putting it all together, we have these 6 macros:

#define JACK_QUEEN_OTHER(u) EXPANSION1(ReSeRvEd_, u, 1, 2, 3)
#define EXPANSION1(a, b, c, d, e) EXPANSION2(a##b, c, d, e)
#define EXPANSION2(a, b, c, d, ...) EXPANSION3(a, b, c, d)
#define EXPANSION3(a, b, c, d, ...) d
#define ReSeRvEd_JACK x,x,x
#define ReSeRvEd_QUEEN x,x

And you might use them like this:

int main() {
#if JACK_QUEEN_OTHER(USER) == 1
  printf("Hello, Jack!\n");
#endif
#if JACK_QUEEN_OTHER(USER) == 2
  printf("Hello, Queen!\n");
#endif
#if JACK_QUEEN_OTHER(USER) == 3
  printf("Hello, who are you?\n");
#endif
}

MSVC Update: You have to parenthesize slightly differently to make things also work in MSVC. The EXPANSION* macros look like this:

#define EXPANSION1(a, b, c, d, e) EXPANSION2((a##b, c, d, e))
#define EXPANSION2(x) EXPANSION3 x
#define EXPANSION3(a, b, c, d, ...) d

I would not use KML. Instead, use GeoJSON which you can natively consume in Google Maps API now. It is a newer feature that didn't exist from the original responses.

In any case, simply open the SHP file in Quantum GIS, and then you can output it in any format you like (KML, GeoJSON).

If you are using Google Maps for Work, I found a premium extension that handles loading shapefiles directly where you can just connect direct to the shapefile that you generate from ESRI. I did a search on the CMaps site and found this snippet which loaded US by state shapefile: https://gmapsplugin.net/cmapsanalytics/assets/shapes/usstates.shp

var cMap = new centigon.locationIntelligence.MapView();
    cMap.key([your_api_key]);


    cMap.layerNames(["Basic Shapes"]);
    cMap.dbfKeys([['Alabama','Alaska','Arizona','Arkansas','California','Colorado','Connecticut','Delaware','District of Columbia','Florida','Georgia','Hawaii','Idaho','Illinois','Indiana','Iowa','Kansas','Kentucky','Louisiana','Maine','Maryland','Massachusetts','Michigan','Minnesota','Mississippi','Missouri','Montana','Nebraska','Nevada','New Hampshire','New Jersey','New Mexico','New York','North Carolina','North Dakota','Ohio','Oklahoma','Oregon','Pennsylvania','Rhode Island','South Carolina','South Dakota','Tennessee','Texas','Utah','Vermont','Virginia','Washington','West Virginia','Wisconsin','Wyoming']]);

That's because the response from chrome.runtime.sendMessage is asynchronous; here's the order of operations:

var newDeals = [];

// (1) first chrome.runtime.sendMessage is called, and *registers a callback*
// so that when the data comes back *in the future*
// the function will be called
chrome.runtime.sendMessage({...}, function(deals) {
  // (3) sometime in the future, this function runs,
  // but it's too late
  newDeals = deals;
});

// (2) this is called immediately, `newDeals` is an empty array
this.setState({ deals: newDeals });

When you pause the script with the debugger, you're giving the extension time to call the callback; by the time you continue, the data has arrived and it appears to work.

To fix, you want to do the setState call after the data comes back from the Chrome extension:

var newDeals = [];

// (1) first chrome.runtime.sendMessage is called, and *registers a callback*
// so that when the data comes back *in the future*
// the function will be called
chrome.runtime.sendMessage({...}, function(deals) {
  // (2) sometime in the future, this function runs
  newDeals = deals;

  // (3) now you can call `setState` with the data
  this.setState({ deals: newDeals });
}.bind(this)); // Don't forget to bind(this) (or use an arrow function)

[Edit]

If this doesn't work for you, check out the other answers on this question, which explain other reasons your component might not be updating.

var Text = File.ReadAllLines("Path"); foreach (var i in Text) {    var SplitText = i.Split().Where(x=> x.Lenght>1).ToList();    //@Array1 add SplitText[0]    //@Array2 add SpliteText[1]   }  

Solution With Less XAML and More C#

If you define the ListView in XAML:

<ListView x:Name="listView"/>

Then you can add columns and populate it in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Add columns
    var gridView = new GridView();
    this.listView.View = gridView;
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Id", DisplayMemberBinding = new Binding("Id") });
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Name", DisplayMemberBinding = new Binding("Name") });

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

Solution With More XAML and less C#

However, it's easier to define the columns in XAML (inside the ListView definition):

<ListView x:Name="listView">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Id" DisplayMemberBinding="{Binding Id}"/>
            <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
        </GridView>
    </ListView.View>
</ListView>

And then just populate the list in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

MyItem Definition

MyItem is defined like this:

public class MyItem
{
    public int Id { get; set; }

    public string Name { get; set; }
}

Here is another simple answer, but without using classes.

from tkinter import *


def raise_frame(frame):
    frame.tkraise()

root = Tk()

f1 = Frame(root)
f2 = Frame(root)
f3 = Frame(root)
f4 = Frame(root)

for frame in (f1, f2, f3, f4):
    frame.grid(row=0, column=0, sticky='news')

Button(f1, text='Go to frame 2', command=lambda:raise_frame(f2)).pack()
Label(f1, text='FRAME 1').pack()

Label(f2, text='FRAME 2').pack()
Button(f2, text='Go to frame 3', command=lambda:raise_frame(f3)).pack()

Label(f3, text='FRAME 3').pack(side='left')
Button(f3, text='Go to frame 4', command=lambda:raise_frame(f4)).pack(side='left')

Label(f4, text='FRAME 4').pack()
Button(f4, text='Goto to frame 1', command=lambda:raise_frame(f1)).pack()

You can simply use setInterval to create such timer in Angular, Use this Code for timer -

timeLeft: number = 60;
  interval;

startTimer() {
    this.interval = setInterval(() => {
      if(this.timeLeft > 0) {
        this.timeLeft--;
      } else {
        this.timeLeft = 60;
      }
    },1000)
  }

  pauseTimer() {
    clearInterval(this.interval);
  }

<button (click)='startTimer()'>Start Timer</button>
<button (click)='pauseTimer()'>Pause</button>

<p>{{timeLeft}} Seconds Left....</p>

Working Example

Another way using Observable timer like below -

import { timer } from 'rxjs';

observableTimer() {
    const source = timer(1000, 2000);
    const abc = source.subscribe(val => {
      console.log(val, '-');
      this.subscribeTimer = this.timeLeft - val;
    });
  }

<p (click)="observableTimer()">Start Observable timer</p> {{subscribeTimer}}

The .navbar-static-top you are using forces your navbar to become full-width. Remove that class and you will get a resizable navbar. Then, you can wrap it in a span# of the size you want.

<div class="container">
<div class="row">
    <div class="span6 offset3">
        <div class="navbar">
            ...
        </div>
    </div>
</div>

function removeAllBlankOrNull(JsonObj) {
    $.each(JsonObj, function(key, value) {
        if (value === "" || value === null) {
            delete JsonObj[key];
        } else if (typeof(value) === "object") {
            JsonObj[key] = removeAllBlankOrNull(value);
        }
    });
    return JsonObj;
}

Deletes all empty strings and null values recursively. Fiddle

This is, unfortunately a quite common problem on Windows where the icons are either not updated or rather disappearing. I find it quite annoying. It usually is fixed by either refreshing the Windows folder (F5) or, by doing a SVN Clean up,

Right click on the folder ->  TortoiseSVN -> Clean up... 
Select Clean up working copy status

I have never been able to solve this permanently, this is only a work-around. Keeping TortoiseSVN on the latest version may or may not help.

Note that the clean up will only clean up your local working copy, it wont do anything to the actual repository. Its a safe operation.

Apparently this is not enough according to your comment. Do you have lots of other programs that are also using overlay icons? If so maybe you can find a solution in this thread: TortoiseSVN icons not showing up under Windows 7? The second most voted answer also deals with network drives etc. Its a good read.

Also, have you rebooted your computer after the install? From the TortoiseSVN FAQ:

You rebooted your PC of course after the installation? If you haven't please do so now. TortoiseSVN is a windows Explorer Shell extension and will be loaded together with Explorer.

...

Otherwise, try doing a repair install (and reboot of course).

If your application is already using Apache Commons lib, you can slightly modify the accepted answer to not create a new empty array each time:

List<String> list = ..;
String[] array = list.toArray(ArrayUtils.EMPTY_STRING_ARRAY);

// or if using static import
String[] array = list.toArray(EMPTY_STRING_ARRAY);

There are a few more preallocated empty arrays of different types in ArrayUtils.

Also we can trick JVM to create en empty array for us this way:

String[] array = list.toArray(ArrayUtils.toArray());

// or if using static import
String[] array = list.toArray(toArray());

But there's really no advantage this way, just a matter of taste, IMO.

I know this post is really old, but I have to reply because although BalusC's answer is marked as correct, it's not completely correct.

You have to write the query adding "[]" to foo like this:

foo[]=val1&foo[]=val2&foo[]=val3

Problems with your code and suggestions:

• Again you need to change the preferredSize of the component (here the Graph JPanel), not the size
• Don't set the JFrame's bounds.
• Call pack() on your JFrame after adding components to it and before calling setVisible(true)
• Your foreach loop won't work since the size of your ArrayList is 0 (test it to see that this is correct). Instead use a for loop going from 0 to 10.
• You should not have program logic inside of your paintComponent(...) method but only painting code. So I would make the ArrayList a class variable and fill it inside of the class's constructor.

Which will create a graph that looks like so:

Maybe something like this:

SELECT count(*) FROM user_tab_columns WHERE table_name = 'FOO'

this will count number of columns in a the table FOO

You can also just

select count(*) from all_tab_columns where owner='BAR' and table_name='FOO';

where the owner is schema and note that Table Names are upper case

    xs: 2,

It looks like this question has a number of answers already, but I'll weigh in with mine since I haven't seen any that address the issue I had.

I had this error as well on a brand new github repository. It turns out the user I was pushing from did not have push access. For some reason, this results in an "ERROR: repository not found" error instead of some sort of access error.

Anyway, I hope this helps the poor soul who runs into the same issue.

This problem mainly happens when you are using connection pooling because when you close connection that connection go back to the connection pool and all cursor associated with that connection never get closed as the connection to database is still open. So one alternative is to decrease the idle connection time of connections in pool, so may whenever connection sits idle in connection for say 10 sec , connection to database will get closed and new connection created to put in pool.

var object = { "a": 1, "b": 2};_x000D_
$.each(object, function(key, value){_x000D_
  console.log(key + ": " + object[key]);_x000D_
});

I share your sense that Interfaces are not necessary. Here is a quote from Cwalina pg 80 Framework Design Guidelines "I often here people saying that interfaces specify contracts. I believe this a dangerous myth. Interfaces by themselves do not specify much. ..." He and co-author Abrams managed 3 releases of .Net for Microsoft. He goes on to say that the 'contract' is "expressed" in an implementation of the class. IMHO watching this for decades, there were many people warning Microsoft that taking the engineering paradigm to the max in OLE/COM might seem good but its usefulness is more directly to hardware. Especially in a big way in the 80s and 90s getting interoperating standards codified. In our TCP/IP Internet world there is little appreciation of the hardware and software gymnastics we would jump through to get solutions 'wired up' between and among mainframes, minicomputers, and microprocessors of which PCs were just a small minority. So coding to interfaces and their protocols made computing work. And interfaces ruled. But what does solving making X.25 work with your application have in common with posting recipes for the holidays? I have been coding C++ and C# for many years and I never created one once.

If you use matplotlib, you need to show the image using plt.show() unless you are not in interactive mode. E.g.:

plt.figure()
plt.imshow(sample_image) 
plt.show()  # display it

Using spacy:

import spacy

nlp = spacy.load('en_core_web_sm')
text = "How are you today? I hope you have a great day"
tokens = nlp(text)
for sent in tokens.sents:
    print(sent.string.strip())

For delayed initialization (i.e. class member constructor initialization) consider:

int a[4];

unsigned int size = sizeof(a) / sizeof(a[0]);
for (unsigned int i = 0; i < size; i++)
  a[i] = 0;

Or you can just run the following command and you will see all databases of the Redis instance without firing up redis-cli:

$ redis-cli INFO | grep ^db
db0:keys=1500,expires=2
db1:keys=200000,expires=1
db2:keys=350003,expires=1

Here's how it works on smallest smartphone (3.7 480x800 Nexus One) vs largest smartphone (5.5 1440x2560 Pixel XL)

It could be that you have not configured the Amazon Security Group assigned to your EC2 Instance to accept incoming requests on port 3306 (default port for MySQL).

If this is the case then you can easily open up the port for the security group in a few button clicks:

1) Log into you AWS Console and go to 'EC2'

2) On the left hand menu under 'Network & Security' go to 'Security Groups'

3) Check the Security Group in question

4) Click on 'Inbound tab'

5) Choose 'MYSQL' from drop down list and click 'Add Rule'

Might not be the reason but worth a go...

In my Firefox this trick works:

function SetPixel(canvas, x, y)
{
  canvas.beginPath();
  canvas.moveTo(x, y);
  canvas.lineTo(x+0.4, y+0.4);
  canvas.stroke();
}

Small offset is not visible on screen, but forces rendering engine to actually draw a point.

1. Check the .aws directory under home directory. Windows: C:\Users<home-name>.aws Linux: ~/.aws

2. Under this directory, you will find the config as well as credentials file. It will have the information from the aws configure that you may have run before. IF not, then

3. Run aws configure Enter the access key - secret key - enter secret key region - (ap-southeast-1 or us-east-1 or any other regions) format - (json or leave it blank, it will pick up default values you may simply hit enter)

4. From the Step 2, you should see the config file, open it, it should have the region. Please ensure there is region specified.

5. You may now run the following command to list the buckets aws s3 ls It should work fine.

function give_array(){

    $a = "abc";
    $b = "def";
    $c = "ghi";

    return compact('a','b','c');
}


$my_array = give_array();

Until now, I was using cmd processes in order to extract an .iso file, copy it into a temporary path from server and extracted on a usb stick. Recently I've found that this is working perfectly with .iso's that are less than 10Gb. For a iso like 29Gb this method gets stuck somehow.

It seems to me like using a REGEX in this case would just be overkill. Why not just just strpos to find the space character. Also, there's nothing special about the space character in regular expressions, you should be able to search for it the same as you would search for any other character. That is, unless you disabled pattern whitespace, which would hardly be necessary in this case.

If you are working with elements of unknown size, and you want to use position: absolute on them or their siblings, you're inevitably going to have to deal with overlap. By setting absolute position you're removing the element from the document flow, but the behaviour you want is that your element should be be pushed around by its siblings so as not to overlap...ie it should flow! You're seeking two totally contradictory things.

You should rethink your layout.

Perhaps what you want is that the .btn element should be absolutely positioned with respect to one of its preceding siblings, rather than against their common parent? In that case, you should set position: relative on the element you'd like to position the button against, and then make the button a child of that element. Now you can use absolute positioning and control overlap.

I'm updating my answer...

antMatcher() is a method of HttpSecurity, it doesn't have anything to do with authorizeRequests(). Basically, http.antMatcher() tells Spring to only configure HttpSecurity if the path matches this pattern.

The authorizeRequests().antMatchers() is then used to apply authorization to one or more paths you specify in antMatchers(). Such as permitAll() or hasRole('USER3'). These only get applied if the first http.antMatcher() is matched.

If you already have var parent = document.querySelector('.parent'); you can do this to scope the search to parent's children:

parent.querySelector('.child')

In Typescript 2 you can use Undefined type to check for undefined values. So if you declare a variable as:

let uemail : string | undefined;

Then you can check if the variable z is undefined as:

if(uemail === undefined)
{

}

string left = "411329_SOFT_MAC_GREEN";
string right= "SOFT_MAC_GREEN";

string[] l = left.Split('_');
string[] r = right.Split('_');

string[] distinctLeft = l.Distinct().ToArray();
string[] distinctRight = r.Distinct().ToArray();

var commonWord = l.Except(r, StringComparer.OrdinalIgnoreCase)
string result = String.Join("_",commonWord);
result = "411329"

postgresql_autodoc is a cli for doing this. Doesnt do cardinality, but none of the above mentioned GUI tools do as well.

A tool is a big help.

However, there are times when you can't use a tool: the heap dump is so huge it crashes the tool, you are trying to troubleshoot a machine in some production environment to which you only have shell access, etc.

In that case, it helps to know your way around the hprof dump file.

Look for SITES BEGIN. This shows you what objects are using the most memory. But the objects aren't lumped together solely by type: each entry also includes a "trace" ID. You can then search for that "TRACE nnnn" to see the top few frames of the stack where the object was allocated. Often, once I see where the object is allocated, I find a bug and I'm done. Also, note that you can control how many frames are recorded in the stack with the options to -Xrunhprof.

If you check out the allocation site, and don't see anything wrong, you have to start backward chaining from some of those live objects to root objects, to find the unexpected reference chain. This is where a tool really helps, but you can do the same thing by hand (well, with grep). There is not just one root object (i.e., object not subject to garbage collection). Threads, classes, and stack frames act as root objects, and anything they reference strongly is not collectible.

To do the chaining, look in the HEAP DUMP section for entries with the bad trace id. This will take you to an OBJ or ARR entry, which shows a unique object identifier in hexadecimal. Search for all occurrences of that id to find who's got a strong reference to the object. Follow each of those paths backward as they branch until you figure out where the leak is. See why a tool is so handy?

Static members are a repeat offender for memory leaks. In fact, even without a tool, it'd be worth spending a few minutes looking through your code for static Map members. Can a map grow large? Does anything ever clean up its entries?

Have in mind that clone() doesn't work out of the box. You will have to implement Cloneable and override the clone() method making in public.

There are a few alternatives, which are preferable (since the clone() method has lots of design issues, as stated in other answers), and the copy-constructor would require manual work:

• BeanUtils.cloneBean(original) creates a shallow clone, like the one created by Object.clone(). (this class is from commons-beanutils)

• SerializationUtils.clone(original) creates a deep clone. (i.e. the whole properties graph is cloned, not only the first level) (from commons-lang), but all classes must implement Serializable

• Java Deep Cloning Library offers deep cloning without the need to implement Serializable

I would use git restore (available since git 2.23)

git restore --source otherbranch path/to/myfile.txt

Why it is better than other options?

git checkout otherbranch -- path/to/myfile.txt - It copy file to working directory but also to staging area (similar effect as if you would copy this file manually and executed git add on it). git restore doesn't touch staging area (unless told it to by --staged option).

git show otherbranch:path/to/myfile.txt > path/to/myfile.txt uses standard shell redirection. If you use Powershell then there might be problem with text enconding or you could get broken file if it's binary. With git restore changing files is done all by git executable.

Another advantage is that you can restore whole folder with:

git restore --source otherbranch path/to

or with git restore --overlay --source otherbranch path/to if you want to avoid deleting files. For example if there is less files on otherbranch than in current working directory (and these files are tracked) without --overlay option git restore will delete them. But this is good default bahaviour, you most likely want the state of directory to be "the same like in otherbranch", not "the same like in otherbranch but with additional files from my current branch"

also had problems with rapidly growing overlay2

/var/lib/docker/overlay2 - is a folder where docker store writable layers for your container. docker system prune -a - may work only if container is stopped and removed.

in my i was able to figure out what consumes space by going into overlay2 and investigating.

that folder contains other hash named folders. each of those has several folders including diff folder.

diff folder - contains actual difference written by a container with exact folder structure as your container (at least it was in my case - ubuntu 18...)

so i've used du -hsc /var/lib/docker/overlay2/LONGHASHHHHHHH/diff/tmp to figure out that /tmp inside of my container is the folder which gets polluted.

so as a workaround i've used -v /tmp/container-data/tmp:/tmp parameter for docker run command to map inner /tmp folder to host and setup a cron on host to cleanup that folder.

cron task was simple:

• sudo nano /etc/crontab
• */30 * * * * root rm -rf /tmp/container-data/tmp/*
• save and exit

NOTE: overlay2 is system docker folder, and they may change it structure anytime. Everything above is based on what i saw in there. Had to go in docker folder structure only because system was completely out of space and even wouldn't allow me to ssh into docker container.

In case you didn't want to create a function, or you needed just a single inline call in T-SQL, you could try:

set @Phone = REPLACE(REPLACE(REPLACE(REPLACE(@Phone,'(',''),' ',''),'-',''),')','')

Of course this is specific to removing phone number formatting, not a generic remove all special characters from string function.

As per HTML5, you can use input type="datetime-local" instead of input type="date".

It will allow the [(ngModel)] directive to read and write value from input control.

Note: If the date string contains 'Z' then to implement above solution, you need to trim the 'Z' character from date.

For more details, please go through this link on mozilla docs.

The following link explains filters in Angular extremely well. It shows how it is possible to define custom sort logic within an ng-repeat. http://toddmotto.com/everything-about-custom-filters-in-angular-js

For sorting object with properties, this is the code I have used: (Note that this sort is the standard JavaScript sort method and not specific to angular) Column Name is the name of the property on which sorting is to be performed.

self.myArray.sort(function(itemA, itemB) {
    if (self.sortOrder === "ASC") {
        return itemA[columnName] > itemB[columnName];
    } else {
        return itemA[columnName] < itemB[columnName];
    }
});

I think the better answer for this questions is

array_diff() 

because it Compares array against one or more other arrays and returns the values in array that are not present in any of the other arrays.

Whereas

array_intersect() returns an array containing all the values of array that are present in all the arguments. Note that keys are preserved.

two objects are equal, implies that they have same hashcode, but not vice versa.

2 equal objects ------> they have same hashcode

2 objects have same hashcode ----xxxxx--> they are NOT equal

Java 8 update in HashMap-

you do this operation in your code -

myHashmap.put("old","old-value");
myHashMap.put("very-old","very-old-value");

so, suppose your hashcode returned for both keys "old" and "very-old" is same. Then what will happen.

myHashMap is a HashMap, and suppose that initially you didn't specify its capacity. So default capacity as per java is 16. So now as soon as you initialised hashmap using the new keyword, it created 16 buckets. now when you executed first statement-

myHashmap.put("old","old-value");

then hashcode for "old" is calculated, and because the hashcode could be very large integer too, so, java internally did this - (hash is hashcode here and >>> is right shift)

hash XOR hash >>> 16

so to give as a bigger picture, it will return some index, which would be between 0 to 15. Now your key value pair "old" and "old-value" would be converted to Entry object's key and value instance variable. and then this entry object will be stored in the bucket, or you can say that at a particular index, this entry object would be stored.

FYI- Entry is a class in Map interface- Map.Entry, with these signature/definition

class Entry{
          final Key k;
          value v;
          final int hash;
          Entry next;
}

now when you execute next statement -

myHashmap.put("very-old","very-old-value");

and "very-old" gives same hashcode as "old", so this new key value pair is again sent to the same index or the same bucket. But since this bucket is not empty, then the next variable of the Entry object is used to store this new key value pair.

and this will be stored as linked list for every object which have the same hashcode, but a TRIEFY_THRESHOLD is specified with value 6. so after this reaches, linked list is converted to the balanced tree(red-black tree) with first element as the root.

Yes, for scalar values, a combination of implode and array_slice will do:

$bar = implode(array_slice($array, 0, 1));
$bin = implode(array_slice($array, 1, 1));
$ipsum = implode(array_slice($array, 2, 1));

Or mix it up with array_values and list (thanks @nikic) so that it works with all types of values:

list($bar) = array_values(array_slice($array, 0, 1));

java.sql.Timestamp is a subclass of java.util.Date. So, just upcast it.

Date dtStart = resultSet.getTimestamp("dtStart");
Date dtEnd = resultSet.getTimestamp("dtEnd");

Using SimpleDateFormat and creating Joda DateTime should be straightforward from this point on.

The + operator uses public String concat(String str) internally. This method copies the characters of the two strings, so it has memory requirements and runtime complexity proportional to the length of the two strings. StringBuilder works more efficent.

However I have read here that the concatination code using the + operater is changed to StringBuilder on post Java 4 compilers. So this might not be an issue at all. (Though I would really check this statement if I depend on it in my code!)

I was having the same trouble with importing from Excel 2010 to Access, appending an "identical" table. Early on in the wizard it said not all my column names were valid, even though I checked them. It turns out that it saw an "empty" column with no column name. When I tried using the import wizard to create a new table instead, it worked. However, I noticed that it had added a blank column to the right of my data and called it "Field30". So I went back to the spreadsheet I was trying to import, selected the columns to the right of the data that I wanted, right-clicked and chose "clear contents." That did the trick and I was able to import the spreadsheet, appending it to my table.

All you need is to create two layouts:

1. an empty layout

2. main layout

Then write the code below in _viewStart file:

@{
   if (Request.IsAjaxRequest())
   {
      Layout = "~/Areas/Dashboard/Views/Shared/_emptyLayout.cshtml";
   }
   else
   {
      Layout = "~/Areas/Dashboard/Views/Shared/_Layout.cshtml";
   }
 }

of course, maybe it is not the best solution

I need to do the same thing for a project I am currently working on. Here is how I solved things:

/* Prompt user for input */
printf("Enter a number: ");

/* Read user input */
char input[255]; //Of course, you can choose a different input size
fgets(input, sizeof(input), stdin);

/* Strip trailing newline */
size_t ln = strlen(input) - 1;
if( input[ln] == '\n' ) input[ln] = '\0';

/* Ensure that input is a number */
for( size_t i = 0; i < ln; i++){
    if( !isdigit(input[i]) ){
        fprintf(stderr, "%c is not a number. Try again.\n", input[i]);
        getInput(); //Assuming this is the name of the function you are using
        return;
    }
}

WHERE datetime_column >= '20081220 00:00:00.000'
  AND datetime_column < '20081221 00:00:00.000'

I recently had a 404 not found error with all my Web Api 2 routes/controllers. So I went onto the actual server and tried to browse using localhost instead of the hostname and got "404.7 Not Found - The request filtering module is configured to deny the file extension".

This SO post help me solve it.

As other posters have said, you need to change the LayoutManager being used. I always preferred using a GridLayout so your code would become:

MainPanel mainPanel = new MainPanel();
JFrame mainFrame = new JFrame();
mainFrame.setLayout(new GridLayout());
mainFrame.pack();
mainFrame.setVisible(true);

GridLayout seems more conceptually correct to me when you want your panel to take up the entire screen.

For a nice looking screencast, have a look at SimFinger. You will still need a screen recoder such as Snapz Pro.

Can you give us a better description and an example of what you are doing? Because all i have to do is put the line in there for the device and then save the file. Now just reconnect the device and it works.

I usually use something similar to this line:

;
;some name for the phone (this seems to be arbitrary)
%CompositeAdbInterface%     = USB_Install, THE_HARDWARE_ID

What i do, is:

1. plug the device into the computer.
2. Go to your device manager.
3. Right click on the device that you plugged up.
4. Go to properties. Then select Hardware Ids.
5. Then get that value that is listed there.
6. Now add it to the line you created in the android_winusb.inf.
7. Unplug the device and plug back in
8. Go back to the device manager
9. Right click on the device and click update or install driver
10. Select search your computer for the driver
11. Select the directory Your_Android_SDK_Directory/extras/google/usb_driver/
12. Press ok

That seems to always work for me, is that what you are doing? Or does this even help?

A table contains data, a view is just a SELECT statement which has been saved in the database (more or less, depending on your database).

The advantage of a view is that it can join data from several tables thus creating a new view of it. Say you have a database with salaries and you need to do some complex statistical queries on it.

Instead of sending the complex query to the database all the time, you can save the query as a view and then SELECT * FROM view

1. Implement a slot in your QMainWindow where you will open your new Window,
2. Place a widget on your QMainWindow,
3. Connect a signal from this widget to a slot from the QMainWindow (for example: if the widget is a QPushButton connect the signal click() to the QMainWindow custom slot you have created).

Code example:

MainWindow.h

// ...
include "newwindow.h"
// ...
public slots:
   void openNewWindow();
// ...
private:
   NewWindow *mMyNewWindow;
// ...
}

MainWindow.cpp

// ...
   MainWindow::MainWindow()
   {
      // ...
      connect(mMyButton, SIGNAL(click()), this, SLOT(openNewWindow()));
      // ...
   }
// ...
void MainWindow::openNewWindow()
{
   mMyNewWindow = new NewWindow(); // Be sure to destroy your window somewhere
   mMyNewWindow->show();
   // ...
}

This is an example on how display a custom new window. There are a lot of ways to do this.

Here is a great way to solve this problem:

Create a rectangle drawable with rounded corners like this:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle"> 
    <stroke android:width="2dp"
            android:color="#888888"/> 

    <corners android:bottomRightRadius="6dp" 
             android:bottomLeftRadius="6dp" 
             android:topLeftRadius="6dp" 
             android:topRightRadius="6dp"/> 
</shape>

save it in the drawable folder with the name rounded_border.xml

Then create a relative layout that uses the rounded_border as a background like this:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" 
    android:background="@drawable/rounded_border">
   <ListView 
       android:id="@+id/list_view"
       android:layout_width="match_parent"
       android:layout_height="wrap_content"/>

</RelativeLayout>

save that in your layout folder and name it table_with_border.xml

then whenever you need such a table pull it into a view using the include syntax like this:

<include
        android:id="@+id/rounded_table"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        layout="@layout/table_with_border" />

You will probably want to add some spacing around the edges - so just wrap the include in a LinearLayout and add some padding around the edges.

Simple and easy way to get a pretty border around a table.

It depends on whether you process IDNs before or after the IDN toASCII algorithm (that is, do you see the domain name pa??de??µa.d???µ? in Greek or as xn--hxajbheg2az3al.xn--jxalpdlp?).

In the latter case—where you are handling IDNs through the punycode—the old RFC 1123 rules apply:

U+0041 through U+005A (A-Z), U+0061 through U+007A (a-z) case folded as each other, U+0030 through U+0039 (0-9) and U+002D (-).

and U+002E (.) of course; the rules for labels allow the others, with dots between labels.

If you are seeing it in IDN form, the allowed characters are much varied, see http://unicode.org/reports/tr36/idn-chars.html for a handy chart of all valid characters.

Chances are your network code will deal with the punycode, but your display code (or even just passing strings to and from other layers) with the more human-readable form as nobody running a server on the ????????. domain wants to see their server listed as being on .xn--mgberp4a5d4ar.

The answers by Richard and Jason are sort of in the right direction. However what you should be doing is computing the effective permissions for the user identity running your code. None of the examples above correctly account for group membership for example.

I'm pretty sure Keith Brown had some code to do this in his wiki version (offline at this time) of The .NET Developers Guide to Windows Security. This is also discussed in reasonable detail in his Programming Windows Security book.

Computing effective permissions is not for the faint hearted and your code to attempt creating a file and catching the security exception thrown is probably the path of least resistance.

If you are using java 8, you can create Comparator by this method:

Comparator.comparingInt(i -> i);

if you would like to compare with reversed order:

Comparator.comparingInt(i -> -i);

If you're like me and you just want to do path-based lookups, but don't care about real XPath, lodash's _.get() can work. Example from lodash docs:

var object = { 'a': [{ 'b': { 'c': 3 } }] };

_.get(object, 'a[0].b.c');
// ? 3

_.get(object, ['a', '0', 'b', 'c']);
// ? 3

_.get(object, 'a.b.c', 'default');
// ? 'default'

I think the proxy_set_header directive could help:

location / {
    proxy_pass http://my_app_upstream;
    proxy_set_header Host $host;
    # ...
}

You should use it for times when you don't want to have to breakpoint every little line of code to check variables, but you do want to get some sort of feedback if certain situations are present, for example:

Debug.Assert(someObject != null, "someObject is null! this could totally be a bug!");

var appBanners = document.getElementsByClassName('appBanner');

for (var i = 0; i < appBanners.length; i ++) {
    appBanners[i].style.display = 'none';
}

JSFiddle.

You need to #include <cstdint>, but that may not always work.

The problem is that some compiler often automatically export names defined in various headers or provided types before such standards were in place.

Now, I said "may not always work." That's because the cstdint header is part of the C++11 standard and is not always available on current C++ compilers (but often is). The stdint.h header is the C equivalent and is part of C99.

For best portability, I'd recommend using Boost's boost/cstdint.hpp header, if you're willing to use boost. Otherwise, you'll probably be able to get away with #include'ing <cstdint>.

but the file i am getting from server after download it gives the size of 226 bytes

This is the size of a ZIP header. Apparently there is no data in the downloaded ZIP file. So, can you verify that the files to be added into the ZIP file are, indeed, there (relative to the path of the download PHP script)?

Consider adding a check on addFile too:

foreach($file_names as $file)
{
    $inputFile = $file_path . $file;
    if (!file_exists($inputFile))
        trigger_error("The input file $inputFile does not exist", E_USER_ERROR);
    if (!is_readable($inputFile))
        trigger_error("The input file $inputFile exists, but has wrong permissions or ownership", E_USER_ERROR);
    if (!$zip->addFile($inputFile, $file))
        trigger_error("Could not add $inputFile to ZIP file", E_USER_ERROR);
}

The observed behaviour is consistent with some problem (path error, permission problems, ...) preventing the files from being added to the ZIP file. On receiving an "empty" ZIP file, the client issues an error referring to the ZIP central directory missing (the actual error being that there is no directory, and no files).

#container img{
 height:100%;
 width:100%;   
}

A handle is whatever you want it to be.

A handle can be a unsigned integer used in some lookup table.

A handle can be a pointer to, or into, a larger set of data.

It depends on how the code that uses the handle behaves. That determines the handle type.

The reason the term 'handle' is used is what is important. That indicates them as an identification or access type of object. Meaning, to the programmer, they represent a 'key' or access to something.

You should have access to the POST dictionary on the request object.

I have uninstalled Microsoft ASP.NET MVC nuget.org from manage NuGet Packagaes and again re-installed it. While re-installing it resolved all the conflicts related to razor version. Try it .

Frames have been deprecated because they caused trouble for url navigation and hyperlinking, because the url would just take to you the index page (with the frameset) and there was no way to specify what was in each of the frame windows. Today, webpages are often generated by server-side technologies such as PHP, ASP.NET, Ruby etc. So instead of using frames, pages can simply be generated by merging a template with content like this:

Template File

<html>
<head>
<title>{insert script variable for title}</title>
</head>

<body>
  <div class="menu">
   {menu items inserted here by server-side scripting}
  </div>
  <div class="main-content">
   {main content inserted here by server-side scripting}
  </div>
</body>
</html>

If you don't have full support for a server-side scripting language, you could also use server-side includes (SSI). This will allow you to do the same thing--i.e. generate a single web page from multiple source documents.

But if you really just want to have a section of your webpage be a separate "window" into which you can load other webpages that are not necessarily located on your own server, you will have to use an iframe.

You could emulate your example like this:

Frames Example

<html>
<head>
  <title>Frames Test</title>
  <style>
   .menu {
      float:left;
      width:20%;
      height:80%;
    }
    .mainContent {
      float:left;
      width:75%;
      height:80%;
    }
  </style>
</head>
<body>
  <iframe class="menu" src="menu.html"></iframe>
  <iframe class="mainContent" src="events.html"></iframe>
</body>
</html>

There are probably better ways to achieve the layout. I've used the CSS float attribute, but you could use tables or other methods as well.

Just change this line:

 <input type="submit" value="Submit" class="submit" />

with this line:

 <input type="submit" value="Submit/Reload" class="submit" onclick="history.go(-1);">

No, the standard way to serialize to JSON is to use an existing JSON serialization library. If you don't wish to do this, then you're going to have to write your own serialization methods.

If you want guidance on how to do this, I'd suggest examining the source of some of the available libraries.

EDIT: I'm not going to come out and say that writing your own serliazation methods is bad, but you must consider that if it's important to your application to use well-formed JSON, then you have to weigh the overhead of "one more dependency" against the possibility that your custom methods may one day encounter a failure case that you hadn't anticipated. Whether that risk is acceptable is your call.

Notice that summary(fit) generates an object with all the information you need. The beta, se, t and p vectors are stored in it. Get the p-values by selecting the 4th column of the coefficients matrix (stored in the summary object):

summary(fit)$coefficients[,4] 
summary(fit)$r.squared

Try str(summary(fit)) to see all the info that this object contains.

Edit: I had misread Chase's answer which basically tells you how to get to what I give here.

I just experienced a similar message [ mine was "Permission denied (publickey)"] after connecting to a compute engine VM which I just created. After reading this post, I decided to try it again.

That time it worked. So i see 3 possible reasons for it working the second time,

• connecting the second time resolves the problem (after the ssh key was created the first time), or
• perhaps trying to connect to a compute engine immediately after it was created could also cause a problem which resolves itself after a while, or
• merely reading this post resolves the problem

I suspect the last is unlikely :)

If you want to know the number of tables that belong to a certain schema/user, you can also use SQL similar to this one:

SELECT Count(*) FROM DBA_TABLES where OWNER like 'PART_OF_NAME%';

Clearly you're passing in d.keys() to your shuffle function. Probably this was written with python2.x (when d.keys() returned a list). With python3.x, d.keys() returns a dict_keys object which behaves a lot more like a set than a list. As such, it can't be indexed.

The solution is to pass list(d.keys()) (or simply list(d)) to shuffle.

I think I like this solution:

import getpass
getpass.getpass("Press Enter to Continue")

It hides whatever the user types in, which helps clarify that input is not used here.

But be mindful on the OS X platform. It displays a key which may be confusing.

Probably the best solution would be to do something similar to the getpass module yourself, without making a read -s call. Maybe making the foreground color match the background?

Maybe SO_REUSEADDR helps here? http://www.unixguide.net/network/socketfaq/4.5.shtml

It's possibly a 32 - 64 bits mismatch.

If you're running on a 64-bit OS, the Assembly RevitAPI may be compiled as 32-bit and your process as 64-bit or "Any CPU".

Or, the RevitAPI is compiled as 64-bit and your process is compiled as 32-bit or "Any CPU" and running on a 32-bit OS.

Short answer

You can see the full table of percentages to hex values and run the code in this playground in https://play.golang.org/p/l1JaPYFzDkI .

Short explanation in pseudocode

Percentage to hex values

1. decimal = percentage * 255 / 100 . ex : decimal = 50*255/100 = 127.5
2. convert decimal to hexadecimal value . ex: 127.5 in decimal = 7*16ˆ1 + 15 = 7F in hexadecimal

Hex values to percentage

1. convert the hexaxdecimal value to decimal. ex: D6 = 13*16ˆ1 + 6 = 214
2. percentage = (value in decimal ) * 100 / 255. ex : 214 *100/255 = 84%

More infos for the conversion decimal <=> hexadecimal

Long answer: how to calculate in your head

The problem can be solved generically by a cross multiplication.

We have a percentage (ranging from 0 to 100 ) and another number (ranging from 0 to 255) then converted to hexadecimal.

• 100 <==> 255 (FF in hexadecimal)
• 0 <==> 0 (00 in hexadecimal)

For 1%

• 1 * 255 / 100 = 2,5
• 2,5 in hexa is 2 if you round it down.

For 2%

• 2 * 255 / 100 = 5
• 5 in hexa is 5 .

The table in the best answer gives the percentage by step of 5%.

How to calculate the numbers between in your head ? Due to the 2.5 increment, add 2 to the first and 3 to the next

• 95% — F2 // start
• 96% — F4 // add 2 to F2
• 97% — F7 // add 3 . Or F2 + 5 = F7
• 98% — F9 // add 2
• 99% — FC // add 3. 9 + 3 = 12 in hexa : C
• 100% — FF // add 2

I prefer to teach how to find the solution rather than showing an answer table you don't know where the results come from.

For integer types, you can do

a ^= b;
b ^= a;
a ^= b;

using the bit-wise xor operator ^. As all the other suggestions, you probably shouldn't use it in production code.

For a reason I don't know, the single line version a ^= b ^= a ^= b doesn't work (maybe my Java compiler has a bug). The single line worked in C with all compilers I tried. However, two-line versions work:

a ^= b ^= a;
b ^= a;

as well as

b ^= a;
a ^= b ^= a;

A proof that it works: Let a0 and b0 be the initial values for a and b. After the first line, a is a1 = a0 xor b0; after the second line, b is b1 = b0 xor a1 = b0 xor (a0 xor b0) = a0. After the third line, a is a2 = a1 xor b1 = a1 xor (b0 xor a1) = b0.

The reason why your full-width-div doesn't stretch 100% to your screen it's because of its parent "container" which occupies only about 80% of the screen.

If you want to make it stretch 100% to the screen either you make the "full-width-div" position fixed or use the "container-fluid" class instead of "container".

You were on the right track with your "ng-keydown" attribute on the input, but you missed a simple step. Just because you put the ng-keydown attribute there, doesn't mean angular knows what to do with it. That's where "directives" come into play. You used the attribute correctly, but you now need to write a directive that will tell angular what to do when it sees that attribute on an html element.

The following is an example of how you would do that. We'll rename the directive from ng-keydown to on-keydown (to avoid breaking the "best practice" found here):

var mod = angular.module('mydirectives');
mod.directive('onKeydown', function() {
    return {
        restrict: 'A',
        link: function(scope, elem, attrs) {
             // this next line will convert the string
             // function name into an actual function
             var functionToCall = scope.$eval(attrs.ngKeydown);
             elem.on('keydown', function(e){
                  // on the keydown event, call my function
                  // and pass it the keycode of the key
                  // that was pressed
                  // ex: if ENTER was pressed, e.which == 13
                  functionToCall(e.which);
             });
        }
    };
});

The directive simple tells angular that when it sees an HTML attribute called "ng-keydown", it should listen to the element that has that attribute and call whatever function is passed to it. In the html you would have the following:

<input type="text" on-keydown="onKeydown">

And then in your controller (just like you already had), you would add a function to your controller's scope that is called "onKeydown", like so:

$scope.onKeydown = function(keycode){
    // do something with the keycode
}

Hopefully that helps either you or someone else who wants to know

You need to select the li tags contained within the .edgetoedge class. .edgetoedge only matches the one ul tag:

PLEASE NOTE - This will not work with IE8-. However, it will work on most versions of Chrome, Firefox and Safari.

An object can only have one prototype. Inheriting from two classes can be done by creating a parent object as a combination of two parent prototypes.

The syntax for subclassing makes it possible to do that in the declaration, since the right-hand side of the extends clause can be any expression. Thus, you can write a function that combines prototypes according to whatever criteria you like, and call that function in the class declaration.

If you compile with debug information on (javac -g), the names of local variables are kept in the .class file. For example, take this simple class:

class TestLocalVarNames {
    public String aMethod(int arg) {
        String local1 = "a string";
        StringBuilder local2 = new StringBuilder();
        return local2.append(local1).append(arg).toString();
    }
}

After compiling with javac -g:vars TestLocalVarNames.java, the names of local variables are now in the .class file. javap's -l flag ("Print line number and local variable tables") can show them.

javap -l -c TestLocalVarNames shows:

class TestLocalVarNames extends java.lang.Object{
TestLocalVarNames();
  Code:
   0:   aload_0
   1:   invokespecial   #1; //Method java/lang/Object."<init>":()V
   4:   return

  LocalVariableTable:
   Start  Length  Slot  Name   Signature
   0      5      0    this       LTestLocalVarNames;

public java.lang.String aMethod(int);
  Code:
   0:   ldc     #2; //String a string
   2:   astore_2
   3:   new     #3; //class java/lang/StringBuilder
   6:   dup
   7:   invokespecial   #4; //Method java/lang/StringBuilder."<init>":()V
   10:  astore_3
   11:  aload_3
   12:  aload_2
   13:  invokevirtual   #5; //Method java/lang/StringBuilder.append:(Ljava/lang/String;)Ljava/lang/StringBuilder;
   16:  iload_1
   17:  invokevirtual   #6; //Method java/lang/StringBuilder.append:(I)Ljava/lang/StringBuilder;
   20:  invokevirtual   #7; //Method java/lang/StringBuilder.toString:()Ljava/lang/String;
   23:  areturn

  LocalVariableTable:
   Start  Length  Slot  Name   Signature
   0      24      0    this       LTestLocalVarNames;
   0      24      1    arg       I
   3      21      2    local1       Ljava/lang/String;
   11      13      3    local2       Ljava/lang/StringBuilder;
}

The VM spec explains what we're seeing here:

§4.7.9 The LocalVariableTable Attribute:

The LocalVariableTable attribute is an optional variable-length attribute of a Code (§4.7.3) attribute. It may be used by debuggers to determine the value of a given local variable during the execution of a method.

The LocalVariableTable stores the names and types of the variables in each slot, so it is possible to match them up with the bytecode. This is how debuggers can do "Evaluate expression".

As erickson said, though, there's no way to access this table through normal reflection. If you're still determined to do this, I believe the Java Platform Debugger Architecture (JPDA) will help (but I've never used it myself).

The same could be done with Perl
Because it uses 0-based-indexing instead of 1-based-indexing, the field values are offset by 1

perl -F, -lane 'print join ",", @F[1..3,5..9,11..19]'    

is equivalent to:

cut -d, -f2-4,6-10,12-20

If the commas are not needed in the output:

perl -F, -lane 'print "@F[1..3,5..9,11..19]"'

  final ProgressDialog loadingDialog = ProgressDialog.show(context,
     "Fetching BloodBank List","Please wait...",false,false);  // for  showing the 
    // dialog  where context is the current context, next field is title followed by
    // message to be shown to the user and in the end intermediate field
    loadingDialog.dismiss();// for dismissing the dialog 

for more info Android - What is difference between progressDialog.show() and ProgressDialog.show()?

Possible. You can get commercial sport also.

JavaFXPorts is the name of the open source project maintained by Gluon that develops the code necessary for Java and JavaFX to run well on mobile and embedded hardware. The goal of this project is to contribute as much back to the OpenJFX project wherever possible, and when not possible, to maintain the minimal number of changes necessary to enable the goals of JavaFXPorts. Gluon takes the JavaFXPorts source code and compiles it into binaries ready for deployment onto iOS, Android, and embedded hardware. The JavaFXPorts builds are freely available on this website for all developers.

Implement your adapter Filterable:

public class vJournalAdapter extends ArrayAdapter<JournalModel> implements Filterable{
private ArrayList<JournalModel> items;
private Context mContext;
....

then create your Filter class:

private class JournalFilter extends Filter{

    @Override
    protected FilterResults performFiltering(CharSequence constraint) {
        FilterResults result = new FilterResults();
        List<JournalModel> allJournals = getAllJournals();
        if(constraint == null || constraint.length() == 0){

            result.values = allJournals;
            result.count = allJournals.size();
        }else{
            ArrayList<JournalModel> filteredList = new ArrayList<JournalModel>();
            for(JournalModel j: allJournals){
                if(j.source.title.contains(constraint))
                    filteredList.add(j);
            }
            result.values = filteredList;
            result.count = filteredList.size();
        }

        return result;
    }
    @SuppressWarnings("unchecked")
    @Override
    protected void publishResults(CharSequence constraint, FilterResults results) {
        if (results.count == 0) {
            notifyDataSetInvalidated();
        } else {
            items = (ArrayList<JournalModel>) results.values;
            notifyDataSetChanged();
        }
    }

}

this way, your adapter is Filterable, you can pass filter item to adapter's filter and do the work. I hope this will be helpful.

Use sp_helptext before the view_name. Example:

sp_helptext Example_1

Hence you will get the query:

CREATE VIEW dbo.Example_1
AS
SELECT       a, b, c
FROM         dbo.table_name JOIN blah blah blah
WHERE        blah blah blah

sp_helptext will give stored procedures.

To retrieve the current directory you can use the dynamic %cd% variable that holds the current active directory

set "curpath=%cd%"

This generates a value with a ending backslash for the root directory, and without a backslash for the rest of directories. You can force and ending backslash for any directory with

for %%a in ("%cd%\") do set "curpath=%%~fa"

Or you can use another dynamic variable: %__CD__% that will return the current active directory with an ending backslash.

Also, remember the %cd% variable can have a value directly assigned. In this case, the value returned will not be the current directory, but the assigned value. You can prevent this with a reference to the current directory

for %%a in (".\") do set "curpath=%%~fa"

Up to windows XP, the %__CD__% variable has the same behaviour. It can be overwritten by the user, but at least from windows 7 (i can't test it on Vista), any change to the %__CD__% is allowed but when the variable is read, the changed value is ignored and the correct current active directory is retrieved (note: the changed value is still visible using the set command).

BUT all the previous codes will return the current active directory, not the directory where the batch file is stored.

set "curpath=%~dp0"

It will return the directory where the batch file is stored, with an ending backslash.

BUT this will fail if in the batch file the shift command has been used

shift
echo %~dp0

As the arguments to the batch file has been shifted, the %0 reference to the current batch file is lost.

To prevent this, you can retrieve the reference to the batch file before any shifting, or change the syntax to shift /1 to ensure the shift operation will start at the first argument, not affecting the reference to the batch file. If you can not use any of this options, you can retrieve the reference to the current batch file in a call to a subroutine

@echo off
    setlocal enableextensions

    rem Destroy batch file reference
    shift
    echo batch folder is "%~dp0"

    rem Call the subroutine to get the batch folder 
    call :getBatchFolder batchFolder
    echo batch folder is "%batchFolder%"

    exit /b

:getBatchFolder returnVar
    set "%~1=%~dp0" & exit /b

This approach can also be necessary if when invoked the batch file name is quoted and a full reference is not used (read here).

You can just controll it with a boolean, so you only call unbind if bind has been made

public void doBindService()
{
    if (!mIsBound)
    {
        bindService(new Intent(this, DMusic.class), Scon, Context.BIND_AUTO_CREATE);
        mIsBound = true;
    }
}

public void doUnbindService()
{
    if (mIsBound)
    {
        unbindService(Scon);
        mIsBound = false;
    }
}

If you only want to unbind it if it has been connected

public ServiceConnection Scon = new ServiceConnection() {

    public void onServiceConnected(ComponentName name, IBinder binder)
    {
        mServ = ((DMusic.ServiceBinder) binder).getService();
        mIsBound = true;
    }

    public void onServiceDisconnected(ComponentName name)
    {
        mServ = null;
    }
};

I found this answer here: https://dba.stackexchange.com/questions/1558. In short using the following (or within my.cnf) will remove the timeout issue.

SET GLOBAL interactive_timeout = 180; SET GLOBAL wait_timeout = 180;

This allows the connections to end if they remain in a sleep State for 3 minutes (or whatever you define).

I have the same issue. I encountered it when I copied an existing project and transferred it on the folder of my solution directory and added it as existing project to my empty solution. So I have to edit my csproj file and look for this specific line of code, most of the time, this is can be found on the last lines:

  <Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />

After that line, I have to comment these out:

  <Import Project="$(SolutionDir)\.nuget\NuGet.targets" Condition="Exists('$(SolutionDir)\.nuget\NuGet.targets')" />
  <Target Name="EnsureNuGetPackageBuildImports" BeforeTargets="PrepareForBuild">
    <PropertyGroup>
      <ErrorText>This project references NuGet package(s) that are missing on this computer. Use NuGet Package Restore to download them.  For more information, see http://go.microsoft.com/fwlink/?LinkID=322105. The missing file is {0}.</ErrorText>
    </PropertyGroup>
    <Error Condition="!Exists('..\..\..\..\..\packages\EntityFramework.6.4.0\build\EntityFramework.props')" Text="$([System.String]::Format('$(ErrorText)', '..\..\..\..\..\packages\EntityFramework.6.4.0\build\EntityFramework.props'))" />
    <Error Condition="!Exists('..\..\..\..\..\packages\EntityFramework.6.4.0\build\EntityFramework.targets')" Text="$([System.String]::Format('$(ErrorText)', '..\..\..\..\..\packages\EntityFramework.6.4.0\build\EntityFramework.targets'))" />
  </Target>
  <Import Project="..\..\..\..\..\packages\EntityFramework.6.4.0\build\EntityFramework.targets" Condition="Exists('..\..\..\..\..\packages\EntityFramework.6.4.0\build\EntityFramework.targets')" />

Your solution will prompt that there was a change on your project, just select Reload All:

Then everything works fine after rebuilding my solution.

I had problems in installing packages on Windows. Found the solution. It works in Windows7+. Mainly anything with Windows Powershell should be able to make it work. This can help you get started with it.

• Firstly, you'll need to add python installation to your PATH variable. This should help.
• You need to download the package in zip format that you are trying to install and unzip it. If it is some odd zip format use 7Zip and it should be extracted.
• Navigate to the directory extracted with setup.py using Windows Powershell (Use link for it if you have problems)
• Run the command python setup.py install

That worked for me when nothing else was making any sense. I use Python 2.7 but the documentation suggests that same would work for Python 3.x also.

A simpler scan would be:

String1.scan(/<(\S+)>/).last

@xtrem's answer is good, but I think the toFixed and the makePercentage are common use. Define two functions, and we can use that at everywhere.

const R = require('ramda')
const RA = require('ramda-adjunct')

const fix = R.invoker(1, 'toFixed')(2)

const makePercentage = R.when(
  RA.isNotNil,
  R.compose(R.flip(R.concat)('%'), fix, R.multiply(100)),
)

let a = 0.9988
let b = null

makePercentage(b) // -> null
makePercentage(a) // -> ?????99.88%?????

• Remember that you (the programmer) has to secure all parts, but the attacker only has to succeed in finding one kink in your armour.
• Security is an example of "unknown unknowns". Sometimes you won't know what the possible security flaws are (until afterwards).
• The difference between a bug and a security hole depends on the intelligence of the attacker.

Also posted here: "background-size: cover" does not cover mobile screen

This works on Android 4.1.2 and iOS 6.1.3 (iPhone 4) and switches for desktop. Written for responsive sites.

Just in case, in your HTML head, something like this:

<meta name="viewport" content="width=device-width, initial-scale=1.0"/>

HTML:

<div class="html-mobile-background"></div>

CSS:

html {
    /* Whatever you want */
}
.html-mobile-background {
    position: fixed;
    z-index: -1;
    top: 0;
    left: 0;
    width: 100%;
    height: 125%; /* To compensate for mobile browser address bar space */
    background: url(/images/bg.jpg) no-repeat; 
    background-size: 100% 100%;
}

@media (min-width: 600px) {
    html {
        background: url(/images/bg.jpg) no-repeat center center fixed; 
        background-size: cover;
    }
    .html-mobile-background {
        display: none;
    }
}

You can use a simple if statement instead of continue. So instead of the way you have your code, you can try:

try(Stream<String> lines = Files.lines(path, StandardCharsets.ISO_8859_1)){
            filteredLines = lines.filter(...).foreach(line -> {
           ...
           if(!...) {
              // Code you want to run
           }
           // Once the code runs, it will continue anyway
    });
}

The predicate in the if statement will just be the opposite of the predicate in your if(pred) continue; statement, so just use ! (logical not).

It looks like you have a 64bit arch, fine -- but a 32bit version of the .NET runtime and/or a 32bit version of Windows.

And as such, the address space available to your process is still the same, it has not changed from your previous setup.

Upgrade to both a 64bit OS and a 64bit .NET version ;)

If you bind your Combobox to something like KeyValuePair, with properties in the constructor like so...:

 DataSource = dataSource,
 DisplayMember = "Value",
 ValueMember = "Key"

so dataSource is of type KeyValuePair...

You end up with having to do this...

  string v = ((KeyValuePair)((ComboBox)c).SelectedItem).Value;

(I had a Dynamic form - where c was of type Control - so had to cast it to ComboBox)

select GROUP_CONCAT(stat SEPARATOR ' ') from (select concat('KILL ',id,';') as stat from information_schema.processlist) as stats;

Then copy and paste the result back into the terminal. Something like:

KILL 2871; KILL 2879; KILL 2874; KILL 2872; KILL 2866;

As @fijaaron says,

1. GRANT ALL does not imply GRANT FILE
2. GRANT FILE only works with *.*

So do

GRANT FILE ON *.* TO user;

The reason #2 fails is because sys.modules['module'] does not exist (the import routine has its own scope, and cannot see the module local name), and there's no module module or package on-disk. Note that you can separate multiple imported names by commas.

from package.subpackage.module import attribute1, attribute2, attribute3

Also:

from package.subpackage import module
print module.attribute1

Come on guys! Nobody mentioned the Guava way to do that (which is arguably awesome):

import com.google.common.base.Stopwatch;

Stopwatch timer = Stopwatch.createStarted();
//method invocation
LOG.info("Method took: " + timer.stop());

The nice thing is that Stopwatch.toString() does a good job of selecting time units for the measurement. I.e. if the value is small, it'll output 38 ns, if it's long, it'll show 5m 3s

Even nicer:

Stopwatch timer = Stopwatch.createUnstarted();
for (...) {
   timer.start();
   methodToTrackTimeFor();
   timer.stop();
   methodNotToTrackTimeFor();
}
LOG.info("Method took: " + timer);

Note: Google Guava requires Java 1.6+

As of Rails 5, the rake commandline tool has been aliased as rails so now

rails db:reset instead of rake db:reset

will work just as well

When using LINQ extension methods (e.g. Select, Where), the lambda function might be converted to SQL that might not behave identically to your C# code. For instance, C#'s short-circuit evaluated && and || are converted to SQL's eager AND and OR. This can cause problems when you're checking for null in your lambda.

Example:

MyEnum? type = null;
Entities.Table.Where(a => type == null || 
    a.type == (int)type).ToArray();  // Exception: Nullable object must have a value

Since every control element gets referenced with its name on the form element (see forms specs), controls with name "submit" will override the build-in submit function.

Which leads to the error mentioned in comments above:

Uncaught TypeError: Property 'submit' of object #<HTMLFormElement> is not a function

As in the accepted answer above the simplest solution would be to change the name of that control element.

However another solution could be to use dispatchEvent method on form element:

$("#form_id")[0].dispatchEvent(new Event('submit')); 

Easiest solution, provide a value of ' ' for the username field (which you can still call 'username').

If the value can be populated by user-inputted values, as is usually the case for a form that you are validating, provide a value of ' ' when it is not already set. In PHP,

if(trim($username) == ''){$username = ' ';}

<input type='text' value = '$username' name = 'Username' />

I actually think autocompletion for username and password effectively gifts access to all your accounts to anyone who accesses your computer, regardless of how obscure your passwords are...

You should have to use DateTime.TryParseExact.

var newDate = DateTime.ParseExact("20111120", 
                                  "yyyyMMdd", 
                                   CultureInfo.InvariantCulture);

OR

string str = "20111021";
string[] format = {"yyyyMMdd"};
DateTime date;

if (DateTime.TryParseExact(str, 
                           format, 
                           System.Globalization.CultureInfo.InvariantCulture,
                           System.Globalization.DateTimeStyles.None, 
                           out date))
{
     //valid
}

Do .libPaths(), close every R runing, check in the first directory, remove the zoo package restart R and install zoo again. Of course you need to have sufficient rights.

The most simple and native way it's to use CURL directly.

This works for me :

<?php
$login = 'login';
$password = 'password';
$url = 'http://your.url';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_USERPWD, "$login:$password");
$result = curl_exec($ch);
curl_close($ch);  
echo($result);

#box {
    display:-ms-flex; /* Older IE Compatibility ;) */
    display:flex;
    justify-content:space-between;
}

The 'justify-content' property makes even the gaps, no matter what's your containing div width.

So, lets say your gap is 10px, you have 4 elements so you have 3 gaps: 3*10px = 30px.

#box .item {
    flex-basis:calc((100% - 30px) /4);    
}

This simple calculation just substracts all gaps added up to the container width, the 'justify-content' property above mentioned takes care of the horizontal alignment. Remaining space is divided by 4 (yep that's our number of elements) giving each .item its width. No other property needed, remember they're already aligned!

Hope this helps!

PS: If you need width in your container you set it, same if the gap size or number of elements change, fix the 'flex-basis' calculation in the .item element to address all of them in one line.

I got around this by upgrading both the version of Angular that I was using (from v8 -> v9) and the version of TypeScript (from 3.5.3 -> latest).

A connection timeout occurs only upon starting the TCP connection. This usually happens if the remote machine does not answer. This means that the server has been shut down, you used the wrong IP/DNS name, wrong port or the network connection to the server is down.

A socket timeout is dedicated to monitor the continuous incoming data flow. If the data flow is interrupted for the specified timeout the connection is regarded as stalled/broken. Of course this only works with connections where data is received all the time.

By setting socket timeout to 1 this would require that every millisecond new data is received (assuming that you read the data block wise and the block is large enough)!

If only the incoming stream stalls for more than a millisecond you are running into a timeout.

java.util.Date date= new Date();
Calendar cal = Calendar.getInstance();
cal.setTime(date);
int month = cal.get(Calendar.MONTH);

Check your line endings! If you see an error about the file not being found, followed by this "premature of end headers" error in your Apache log - it may be that you have Windows line endings in your script in instead of Unix style. I ran into that problem / solution.

To solve this for several columns of a dataframe:

This answer was inspired from Anamika Modi's answer. Thank you!

So, @Vivek has got the solution to the problem through a dialogue in the Comments rather than through an actual answer.

"The file is being created by user oracle just noticed this in our development database. i'm getting this error because, the directory where i try to create the file doesn't have write access for others and user oracle comes under others category. "

Who says SO is a Q&A site not a forum? Er, me, amongst others. Anyway, in the absence of an accepted answer to this question I proffer a link to an answer of mine on the topic of UTL_FILE.FOPEN(). Find it here.

P.S. I'm marking this answer Community Wiki, because it's not a proper answer to this question, just a redirect to somewhere else.

Just for the sake of people who landed here for the same reason I did:

Don't use reserved keywords

I named a function in my class definition delete(), which is a reserved keyword and should not be used as a function name. Renaming it to deletion() (which also made sense semantically in my case) resolved the issue.

For a list of reserved keywords: http://en.cppreference.com/w/cpp/keyword

I quote: "Since they are used by the language, these keywords are not available for re-definition or overloading. "

I usually do the following:

:Check_Architecture
if /i "%processor_architecture%"=="x86" (
    IF NOT DEFINED PROCESSOR_ARCHITEW6432 (
        REM Run 32 bit command

    ) ELSE (
        REM Run 64 bit command
    )           
) else (
        REM Run 64 bit command
)

I found a complete solution!

Most answers tell you to kill the process, however with process hacker, I couldn't find any.

I found a relatively simple solution.

1. Select your primary form in the Form Designer.
2. Click to your events tab on the properties menu.
3. Doubleclick the event FormClosing. This automatically generates the event system and function:

private void [your form name here]_FormClosing(object sender, FormClosingEventArgs e)

4. Inside this function, add Application.Exit

Like so:

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
    Application.Exit();
}

I hope this helps! This problem really sucked!

Fix 2

Turn on a service called 'Application Experience.'

Usefull script which you can delete all data in all tables of a database , replace tt with you databse name :

declare @tablename nvarchar(100)
declare c1 cursor for

open  c1
fetch next from c1 into @tablename

while @@FETCH_STATUS = 0
    begin
    print @t1

json works with Unicode text in Python 3 (JSON format itself is defined only in terms of Unicode text) and therefore you need to decode bytes received in HTTP response. r.headers.get_content_charset('utf-8') gets your the character encoding:

#!/usr/bin/env python3
import io
import json
from urllib.request import urlopen

with urlopen('https://httpbin.org/get') as r, \
     io.TextIOWrapper(r, encoding=r.headers.get_content_charset('utf-8')) as file:
    result = json.load(file)
print(result['headers']['User-Agent'])

It is not necessary to use io.TextIOWrapper here:

#!/usr/bin/env python3
import json
from urllib.request import urlopen

with urlopen('https://httpbin.org/get') as r:
    result = json.loads(r.read().decode(r.headers.get_content_charset('utf-8')))
print(result['headers']['User-Agent'])

If you need to setup this after the modal is shown, you can use @Nabid solution. However, sometimes you still need to allow some method to close the modal. Assuming you have a button with class really-close-the-modal, which should really close the modal, you can use this code (jquery):

var closeButtonClicked = false;

$('.really-close-the-modal').on('click', function () {
    closeButtonClicked = true;
});

$('#myModal').on('hide.bs.modal', function (e) {
    if (!closeButtonClicked) {
        e.preventDefault();
        e.stopPropagation();
        return false;
    }
    closeButtonClicked = false;
});

This isn't really nice code design, but it helped me in a situation where the modal was shown with a loader animation, until an ajax request returned, and only then could I know if the modal needed to be configured to prevent "implicit" closing. You can use a similar design to prevent closing the modal while it's still loading.

First of all what value do you have in this pice of code? int temp;? You can't tell because in every single compilation it will have different value - you should initialize your value to not have trash value from memory. Next question is: why you assign this temp value to your array? If you want to stick with your solution I would change reverse function like this:

void reverse(int arr[], int count)
{
    int temp = 0;
    for (int i = 0; i < count/2; ++i)
    {
        temp = arr[count - i - 1];
        arr[count - i - 1] = arr[i];
        arr[i] = temp;
    }

    for (int i = 0; i < count; ++i)
    {
        std::cout << arr[i] << " ";
    }
}

Now it will works but you have other options to handle this problem.

Solution using pointers:

void reverse(int arr[], int count)
{
    int* head = arr;
    int* tail = arr + count - 1;
    for (int i = 0; i < count/2; ++i)
    {
        if (head < tail)
        {
            int tmp = *tail;
            *tail = *head;
            *head = tmp;

            head++; tail--;
        }
    }

    for (int i = 0; i < count; ++i)
    {
        std::cout << arr[i] << " ";
    }
}

And ofc like Carlos Abraham says use build in function in algorithm library

Remove-Item -LiteralPath "foldertodelete" -Force -Recurse

You need to use cell-arrays:

names = cell(10,1);
for i=1:10
    names{i} = ['Sample Text ' num2str(i)];
end

This writes a Byte Order Mark at the start of the file, which is unnecessary in a UTF-8 file and some applications (in my case, SAP) don't like it. Solution here: Can I export excel data with UTF-8 without BOM?

Two important notes:

1. You need to call layoutIfNeeded within the animation block. Apple actually recommends you call it once before the animation block to ensure that all pending layout operations have been completed

2. You need to call it specifically on the parent view (e.g. self.view), not the child view that has the constraints attached to it. Doing so will update all constrained views, including animating other views that might be constrained to the view that you changed the constraint of (e.g. View B is attached to the bottom of View A and you just changed View A's top offset and you want View B to animate with it)

Try this:

Objective-C

- (void)moveBannerOffScreen {
    [self.view layoutIfNeeded];

    [UIView animateWithDuration:5
        animations:^{
            self._addBannerDistanceFromBottomConstraint.constant = -32;
            [self.view layoutIfNeeded]; // Called on parent view
        }];
    bannerIsVisible = FALSE;
}

- (void)moveBannerOnScreen { 
    [self.view layoutIfNeeded];

    [UIView animateWithDuration:5
        animations:^{
            self._addBannerDistanceFromBottomConstraint.constant = 0;
            [self.view layoutIfNeeded]; // Called on parent view
        }];
    bannerIsVisible = TRUE;
}

Swift 3

UIView.animate(withDuration: 5) {
    self._addBannerDistanceFromBottomConstraint.constant = 0
    self.view.layoutIfNeeded()
}

From the Android Studio download page:

Caution: Android Studio is currently available as an early access preview. Several features are either incomplete or not yet implemented and you may encounter bugs. If you are not comfortable using an unfinished product, you may want to instead download (or continue to use) the ADT Bundle (Eclipse with the ADT Plugin).

your fadeIn() function calls the fadeOut() function, which calls the fadeIn() function again. the recursion is in the JS.

It looks like you are trying to start the Python interpreter by running the command python.

However the interpreter is already started. It is interpreting python as a name of a variable, and that name is not defined.

Try this instead and you should hopefully see that your Python installation is working as expected:

print("Hello world!")

Edit: It's now six years since the original answer was written and a lot has changed!

• If you're using a newer version of JavaScript, possibly compiled with a tool like Babel, you can use real classes.
• If you're using the class-like component constructors provided by Angular or React, you'll want to look in the docs for that framework.
• If you're using ES5 and making "fake" classes by hand using prototypes, the answer below is still as right as it ever was.

Good luck!

JavaScript inheritance looks a bit different from Java. Here is how the native JavaScript object system looks:

// Create a class
function Vehicle(color){
  this.color = color;
}

// Add an instance method
Vehicle.prototype.go = function(){
  return "Underway in " + this.color;
}

// Add a second class
function Car(color){
  this.color = color;
}

// And declare it is a subclass of the first
Car.prototype = new Vehicle();

// Override the instance method
Car.prototype.go = function(){
  return Vehicle.prototype.go.call(this) + " car"
}

// Create some instances and see the overridden behavior.
var v = new Vehicle("blue");
v.go() // "Underway in blue"

var c = new Car("red");
c.go() // "Underway in red car"

Unfortunately this is a bit ugly and it does not include a very nice way to "super": you have to manually specify which parent classes' method you want to call. As a result, there are a variety of tools to make creating classes nicer. Try looking at Prototype.js, Backbone.js, or a similar library that includes a nicer syntax for doing OOP in js.

eval() can not handle the list object

tf.reset_default_graph()

a = tf.Variable(0.2, name="a")
b = tf.Variable(0.3, name="b")
z = tf.constant(0.0, name="z0")
for i in range(100):
    z = a * tf.cos(z + i) + z * tf.sin(b - i)
grad = tf.gradients(z, [a, b])

init = tf.global_variables_initializer()

with tf.Session() as sess:
    init.run()
    print("z:", z.eval())
    print("grad", grad.eval())

but Session.run() can

print("grad", sess.run(grad))

correct me if I am wrong
