If you're working with an asp.net application and you want to locate assemblies when using the debugger, they are usually put into some temp directory. I wrote the this method to help with that scenario.

private string[] GetAssembly(string[] assemblyNames)
{
    string [] locations = new string[assemblyNames.Length];


    for (int loop = 0; loop <= assemblyNames.Length - 1; loop++)       
    {
         locations[loop] = AppDomain.CurrentDomain.GetAssemblies().Where(a => !a.IsDynamic && a.ManifestModule.Name == assemblyNames[loop]).Select(a => a.Location).FirstOrDefault();
    }
    return locations;
}

If you can't change the source code, or redeploy, but you can examine the running processes on the computer use Process Explorer. I written a detailed description here.

It will list all executing dlls on the system, you may need to determine the process id of your running application, but that is usually not too difficult.

I've written a full description of how do this for a dll inside IIS - http://nodogmablog.bryanhogan.net/2016/09/locating-and-checking-an-executing-dll-on-a-running-web-server/

Check the properties of App.xaml. Is the Build Action still ApplicationDefinition?

I found a solution that worked in my case:

<input class="form-control" style="min-width: 100%!important;" type="text" />

You only need to override the min-width set 100% and important and the result is this one:

If you don't apply it, you will always get this:

My select2 element was not firing the onchange event as the drop down list offered only one value, making it impossible to change the value.

The value not having changed, no event was fired and the handler could not execute.

I then added another handler to clear the value, with the select2-open handler being executed before the onchange handler.

The source code now looks like:

el.on("select2-open", function(e) {
    $(this).val('');
});
el.on('change', function() {
    ...
});

The first handler clears the value, allowing the second handler to fire up even if selecting the same value.

TL;DR

Error #1064 means that MySQL can't understand your command. To fix it:

• Read the error message. It tells you exactly where in your command MySQL got confused.

• Examine your command. If you use a programming language to create your command, use echo, console.log(), or its equivalent to show the entire command so you can see it.

• Check the manual. By comparing against what MySQL expected at that point, the problem is often obvious.

• Check for reserved words. If the error occurred on an object identifier, check that it isn't a reserved word (and, if it is, ensure that it's properly quoted).

1. Aaaagh!! What does #1064 mean?

   Error messages may look like gobbledygook, but they're (often) incredibly informative and provide sufficient detail to pinpoint what went wrong. By understanding exactly what MySQL is telling you, you can arm yourself to fix any problem of this sort in the future.

   As in many programs, MySQL errors are coded according to the type of problem that occurred. Error #1064 is a syntax error.

   • What is this "syntax" of which you speak? Is it witchcraft?

     Whilst "syntax" is a word that many programmers only encounter in the context of computers, it is in fact borrowed from wider linguistics. It refers to sentence structure: i.e. the rules of grammar; or, in other words, the rules that define what constitutes a valid sentence within the language.

     For example, the following English sentence contains a syntax error (because the indefinite article "a" must always precede a noun):

     This sentence contains syntax error a.

   • What does that have to do with MySQL?

     Whenever one issues a command to a computer, one of the very first things that it must do is "parse" that command in order to make sense of it. A "syntax error" means that the parser is unable to understand what is being asked because it does not constitute a valid command within the language: in other words, the command violates the grammar of the programming language.

     It's important to note that the computer must understand the command before it can do anything with it. Because there is a syntax error, MySQL has no idea what one is after and therefore gives up before it even looks at the database and therefore the schema or table contents are not relevant.

2. How do I fix it?

   Obviously, one needs to determine how it is that the command violates MySQL's grammar. This may sound pretty impenetrable, but MySQL is trying really hard to help us here. All we need to do is…

   • Read the message!

     MySQL not only tells us exactly where the parser encountered the syntax error, but also makes a suggestion for fixing it. For example, consider the following SQL command:

     UPDATE my_table WHERE id=101 SET name='foo'
     

     That command yields the following error message:

     ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE id=101 SET name='foo'' at line 1

     MySQL is telling us that everything seemed fine up to the word WHERE, but then a problem was encountered. In other words, it wasn't expecting to encounter WHERE at that point.

     Messages that say ...near '' at line... simply mean that the end of command was encountered unexpectedly: that is, something else should appear before the command ends.

   • Examine the actual text of your command!

     Programmers often create SQL commands using a programming language. For example a php program might have a (wrong) line like this:

     $result = $mysqli->query("UPDATE " . $tablename ."SET name='foo' WHERE id=101");
     

     If you write this this in two lines

     $query = "UPDATE " . $tablename ."SET name='foo' WHERE id=101"
     $result = $mysqli->query($query);
     

     then you can add echo $query; or var_dump($query) to see that the query actually says

     UPDATE userSET name='foo' WHERE id=101
     

     Often you'll see your error immediately and be able to fix it.

   • Obey orders!

     MySQL is also recommending that we "check the manual that corresponds to our MySQL version for the right syntax to use". Let's do that.

     I'm using MySQL v5.6, so I'll turn to that version's manual entry for an UPDATE command. The very first thing on the page is the command's grammar (this is true for every command):

     UPDATE [LOW_PRIORITY] [IGNORE] table_reference
         SET col_name1={expr1|DEFAULT} [, col_name2={expr2|DEFAULT}] ...
         [WHERE where_condition]
         [ORDER BY ...]
         [LIMIT row_count]
     

     The manual explains how to interpret this syntax under Typographical and Syntax Conventions, but for our purposes it's enough to recognise that: clauses contained within square brackets [ and ] are optional; vertical bars | indicate alternatives; and ellipses ... denote either an omission for brevity, or that the preceding clause may be repeated.

     We already know that the parser believed everything in our command was okay prior to the WHERE keyword, or in other words up to and including the table reference. Looking at the grammar, we see that table_reference must be followed by the SET keyword: whereas in our command it was actually followed by the WHERE keyword. This explains why the parser reports that a problem was encountered at that point.

   A note of reservation

   Of course, this was a simple example. However, by following the two steps outlined above (i.e. observing exactly where in the command the parser found the grammar to be violated and comparing against the manual's description of what was expected at that point), virtually every syntax error can be readily identified.

   I say "virtually all", because there's a small class of problems that aren't quite so easy to spot—and that is where the parser believes that the language element encountered means one thing whereas you intend it to mean another. Take the following example:

   UPDATE my_table SET where='foo'
   

   Again, the parser does not expect to encounter WHERE at this point and so will raise a similar syntax error—but you hadn't intended for that where to be an SQL keyword: you had intended for it to identify a column for updating! However, as documented under Schema Object Names:

   If an identifier contains special characters or is a reserved word, you must quote it whenever you refer to it. (Exception: A reserved word that follows a period in a qualified name must be an identifier, so it need not be quoted.) Reserved words are listed at Section 9.3, “Keywords and Reserved Words”.

   [ deletia ]

   The identifier quote character is the backtick (“`”):

   mysql> SELECT * FROM `select` WHERE `select`.id > 100;

   If the ANSI_QUOTES SQL mode is enabled, it is also permissible to quote identifiers within double quotation marks:

   mysql> CREATE TABLE "test" (col INT);
   ERROR 1064: You have an error in your SQL syntax...
   mysql> SET sql_mode='ANSI_QUOTES';
   mysql> CREATE TABLE "test" (col INT);
   Query OK, 0 rows affected (0.00 sec)

    public async Task<ActionResult> Index()
    {
        apiTable table = new apiTable();
        table.Name = "Asma Nadeem";
        table.Roll = "6655";

        string str = "";
        string str2 = "";

        HttpClient client = new HttpClient();

        string json = JsonConvert.SerializeObject(table);

        StringContent httpContent = new StringContent(json, System.Text.Encoding.UTF8, "application/json");

        var response = await client.PostAsync("http://YourSite.com/api/apiTables", httpContent);

        str = "" + response.Content + " : " + response.StatusCode;

        if (response.IsSuccessStatusCode)
        {       
            str2 = "Data Posted";
        }

        return View();
    }

How about:

df <- data.frame(matrix(ncol = 3, nrow = 0))
x <- c("name", "age", "gender")
colnames(df) <- x

To do all these operations in one-liner:

setNames(data.frame(matrix(ncol = 3, nrow = 0)), c("name", "age", "gender"))

#[1] name   age    gender
#<0 rows> (or 0-length row.names)

Or

data.frame(matrix(ncol=3,nrow=0, dimnames=list(NULL, c("name", "age", "gender"))))

tl;dr

myPreparedStatement.setObject(   // Directly exchange java.time objects with database without the troublesome old java.sql.* classes.
    … ,                                   
    LocalDate.parse(             // Parse string as a `LocalDate` date-only value.
        "2018-01-23"             // Input string that complies with standard ISO 8601 formatting.
    ) 
)

java.time

The modern approach uses the java.time classes that supplant the troublesome old legacy classes such as java.util.Date and java.sql.Date.

For a date-only value, use LocalDate. The LocalDate class represents a date-only value without time-of-day and without time zone.

The java.time classes use standard formats when parsing/generating strings. So no need to specify a formatting pattern.

LocalDate ld = LocalDate.parse( input ) ;

You can directly exchange java.time objects with your database using a JDBC driver compliant with JDBC 4.2 or later. You can forget about transforming in and out of java.sql.* classes.

myPreparedStatement.setObject( … , ld ) ;

Retrieval:

LocalDate ld = myResultSet.getObject( … , LocalDate.class ) ;

About java.time

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

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

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

Where to obtain the java.time classes?

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

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

Id be inclined to create classes that match the structure and add an instance to a collection then serialise and deserialise the collection to load and save the document.

Try this

Change the order of files it should be like below..

<script src="js/jquery-1.11.0.min.js"></script>
<script src="js/bootstrap.min.js"></script>
<script src="js/wow.min.js"></script>

The advantage is that Object.create is typically slower than new on most browsers

In this jsperf example, in a Chromium, browser new is 30 times as fast as Object.create(obj) although both are pretty fast. This is all pretty strange because new does more things (like invoking a constructor) where Object.create should be just creating a new Object with the passed in object as a prototype (secret link in Crockford-speak)

Perhaps the browsers have not caught up in making Object.create more efficient (perhaps they are basing it on new under the covers ... even in native code)

startMode="alwaysRunning" in $SOLUTION_DIR/bis/.vs/config/applicationhost.config caused it for me. Try to remove that string and everything will work again (even without restart of VS)

Before you run a select query, run this:

SET SERVEROUT ON SIZE 6000

SELECT XMLAGG(XMLELEMENT(E,SUPLR_SUPLR_ID||',')).EXTRACT('//text()') "SUPPLIER" 
FROM SUPPLIERS;

call concat and pass param axis=1 to concatenate column-wise:

In [5]:

pd.concat([df_a,df_b], axis=1)
Out[5]:

There is a useful guide to the various methods of merging, joining and concatenating online.

For example, as you have no clashing columns you can merge and use the indices as they have the same number of rows:

In [6]:

df_a.merge(df_b, left_index=True, right_index=True)
Out[6]:
        AAseq Biorep  Techrep Treatment     mz      AAseq1 Biorep1  Techrep1  \

2          C   1010  

And for the same reasons as above a simple join works too:

In [7]:

df_a.join(df_b)
Out[7]:
        AAseq Biorep  Techrep Treatment     mz      AAseq1 Biorep1  Techrep1  \

Answering your question in Dhara's answer comments: "I would like on the second x-axis these tics: (7,8,99) corresponding to the x-axis position 10, 30, 40. Is that possible in some way?" Yes, it is.

import numpy as np
import matplotlib.pyplot as plt

fig = plt.figure()
ax1 = fig.add_subplot(111)

a = np.cos(2*np.pi*np.linspace(0, 1, 60.))
ax1.plot(range(60), a)

ax1.set_xlim(0, 60)
ax1.set_xlabel("x")
ax1.set_ylabel("y")

ax2 = ax1.twiny()
ax2.set_xlabel("x-transformed")
ax2.set_xlim(0, 60)
ax2.set_xticks([10, 30, 40])
ax2.set_xticklabels(['7','8','99'])

plt.show()

You'll get:

Use this condition:

if (jQuery(".profile-page-cont").css('display') == 'block'){

Not gonna write full code, but I did a sudoku solver a long time ago. I found that it didn't always solve it (the thing people do when they have a newspaper is incomplete!), but now think I know how to do it.

• Setup: for each square, have a set of flags for each number showing the allowed numbers.
• Crossing out: just like when people on the train are solving it on paper, you can iteratively cross out known numbers. Any square left with just one number will trigger another crossing out. This will either result in solving the whole puzzle, or it will run out of triggers. This is where I stalled last time.
• Permutations: there's only 9! = 362880 ways to arrange 9 numbers, easily precomputed on a modern system. All of the rows, columns, and 3x3 squares must be one of these permutations. Once you have a bunch of numbers in there, you can do what you did with the crossing out. For each row/column/3x3, you can cross out 1/9 of the 9! permutations if you have one number, 1/(8*9) if you have 2, and so forth.
• Cross permutations: Now you have a bunch of rows and columns with sets of potential permutations. But there's another constraint: once you set a row, the columns and 3x3s are vastly reduced in what they might be. You can do a tree search from here to find a solution.

You can do this with the reshape() function, or with the melt() / cast() functions in the reshape package. For the second option, example code is

library(reshape)
cast(dat1, name ~ numbers)

Or using reshape2

library(reshape2)
dcast(dat1, name ~ numbers)

DateTime is not a function, but the class.

When you just reference a class like new DateTime() PHP searches for the class in your current namespace. However the DateTime class obviously doesn't exists in your controllers namespace but rather in root namespace.

You can either reference it in the root namespace by prepending a backslash:

$now = new \DateTime();

Or add an import statement at the top:

use DateTime;

$now = new DateTime();

I have shamelessly pulled some pretty big datasets in memory, and altough it did get sluggish it took maybe 15 Mo of data upwards with pretty intense calculations on the dataset. I doubt you will run into problems with memory unless you have intense calculations on the data and many many rows. Profiling and benchmarking with different mock resultsets will be your best bet to evaluate performance.

Please note that as of 2016, ReCaptcha doesn't naively support localhost anymore. From the FAQ:

localhost domains are no longer supported by default. If you wish to continue supporting them for development you can add them to the list of supported domains for your site key. Go to the admin console to update your list of supported domains. We advise to use a separate key for development and production and to not allow localhost on your production site key.

So just add localhost to your list of domains for your site and you'll be good.

Other than all the amazing answers here, there is a way to use getattr to save copious lines of code and keeping it snug. This thought came following the dreadful representation of code that sometimes might be a necessity.

Scenario

Suppose your directory structure is as follows:

- superheroes.py
- properties.py

And, you have functions for getting information about Thor, Iron Man, Doctor Strange in superheroes.py. You very smartly write down the properties of all of them in properties.py in a compact dict and then access them.

properties.py

thor = {
    'about': 'Asgardian god of thunder',
    'weapon': 'Mjolnir',
    'powers': ['invulnerability', 'keen senses', 'vortex breath'], # and many more
}
iron_man = {
    'about': 'A wealthy American business magnate, playboy, and ingenious scientist',
    'weapon': 'Armor',
    'powers': ['intellect', 'armor suit', 'interface with wireless connections', 'money'],
}
doctor_strange = {
    'about': ' primary protector of Earth against magical and mystical threats',
    'weapon': 'Magic',
    'powers': ['magic', 'intellect', 'martial arts'],
}

Now, let's say you want to return capabilities of each of them on demand in superheroes.py. So, there are functions like

from .properties import thor, iron_man, doctor_strange


def get_thor_weapon():
    return thor['weapon']


def get_iron_man_bio():
    return iron_man['about']


def get_thor_powers():
    return thor['powers']

...and more functions returning different values based on the keys and superhero.

With the help of getattr, you could do something like:

from . import properties


def get_superhero_weapon(hero):
    superhero = getattr(properties, hero)
    return superhero['weapon']


def get_superhero_powers(hero):
    superhero = getattr(properties, hero)
    return superhero['powers']

You considerably reduced the number of lines of code, functions and repetition!

Oh and of course, if you have bad names like properties_of_thor for variables , they can be made and accessed by simply doing

def get_superhero_weapon(hero):
    superhero = 'properties_of_{}'.format(hero)
    all_properties = getattr(properties, superhero)
    return all_properties['weapon']

NOTE: For this particular problem, there can be smarter ways to deal with the situation, but the idea is to give an insight about using getattr in right places to write cleaner code.

Roman, if you want to do your layout in Java code (ViewGroup descendant), it is possible. The trick is that you have to implement both onMeasure and onLayout methods. The onMeasure gets called first and you need to "measure" the subview (effectively sizing it to the desired value) there. You need to size it again in the onLayout call. If you fail to do this sequence or fail to call setMeasuredDimension() at the end of your onMeasure code, you won't get results. Why is this designed in such complicated and fragile way is beyond me.

In addition, it's convenient to define variables referring to objects. For instance,

Sub CreateTable()
    Dim lo as ListObject
    Set lo = ActiveSheet.ListObjects.Add(xlSrcRange, Range("$B$1:$D$16"), , xlYes)
    lo.Name = "Table1"
    lo.TableStyle = "TableStyleLight2"
    ...
End Sub

You will probably find it advantageous at once.

I found a very good answer here which explains when to use what in simple words:

The basic rule of thumb for which framework to use is how to plan on editing your data in your presentation layer.

• Linq-To-Sql - use this framework if you plan on editing a one-to-one relationship of your data in your presentation layer. Meaning you don't plan on combining data from more than one table in any one view or page.

• Entity Framework - use this framework if you plan on combining data from more than one table in your view or page. To make this clearer, the above terms are specific to data that will be manipulated in your view or page, not just displayed. This is important to understand.

With the Entity Framework you are able to "merge" tabled data together to present to the presentation layer in an editable form, and then when that form is submitted, EF will know how to update ALL the data from the various tables.

There are probably more accurate reasons to choose EF over L2S, but this would probably be the easiest one to understand. L2S does not have the capability to merge data for view presentation.

I faced the same issue. String.Replace('\\.','') is not valid statement and throws the same error. Thanks to C# we can use double quotes instead of single quotes and following works String.Replace("\\.","")

Here is the Class Component code snippet you can use to solve this problem:

This approach used the ref and also scrolls smoothly to the target ref

import React, { Component } from 'react'

export default class Untitled extends Component {
  constructor(props) {
    super(props)
    this.howItWorks = React.createRef() 
  }

  scrollTohowItWorks = () =>  window.scroll({
    top: this.howItWorks.current.offsetTop,
    left: 0,
    behavior: 'smooth'
  });

  render() {
    return (
      <div>
       <button onClick={() => this.scrollTohowItWorks()}>How it works</button>
       <hr/>
       <div className="content" ref={this.howItWorks}>
         Lorem ipsum dolor, sit amet consectetur adipisicing elit. Nesciunt placeat magnam accusantium aliquid tenetur aspernatur nobis molestias quam. Magnam libero expedita aspernatur commodi quam provident obcaecati ratione asperiores, exercitationem voluptatum!
       </div>
      </div>
    )
  }
}

List of One Liners

Let's solve this problem for this array:

var array = ['A', 'B', 'C'];

1. Remove only the first: Use If you are sure that the item exist

array.splice(array.indexOf('B'), 1);

2. Remove only the last: Use If you are sure that the item exist

array.splice(array.lastIndexOf('B'), 1);

3. Remove all occurrences:

array = array.filter(v => v !== 'B'); 

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

So, in JS:

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

In Controller:

var model = _newPoints;
return PartialView(model);

In View

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

The basic idea of static import is that whenever you are using a static class,a static variable or an enum,you can import them and save yourself from some typing.

I will elaborate my point with example.

import java.lang.Math;

class WithoutStaticImports {

 public static void main(String [] args) {
  System.out.println("round " + Math.round(1032.897));
  System.out.println("min " + Math.min(60,102));
 }
}

Same code, with static imports:

import static java.lang.System.out;
import static java.lang.Math.*;

class WithStaticImports {
  public static void main(String [] args) {
    out.println("round " + round(1032.897));
    out.println("min " + min(60,102));
  }
}

Note: static import can make your code confusing to read.

This should work fine.

    Workbook wb = new XSSFWorkbook("myWorkbook.xlsx");
    Row row=sheet.getRow(0);
    CellStyle style=null;

    XSSFFont defaultFont= wb.createFont();
    defaultFont.setFontHeightInPoints((short)10);
    defaultFont.setFontName("Arial");
    defaultFont.setColor(IndexedColors.BLACK.getIndex());
    defaultFont.setBold(false);
    defaultFont.setItalic(false);

    XSSFFont font= wb.createFont();
    font.setFontHeightInPoints((short)10);
    font.setFontName("Arial");
    font.setColor(IndexedColors.WHITE.getIndex());
    font.setBold(true);
    font.setItalic(false);

    style=row.getRowStyle();
    style.setFillBackgroundColor(IndexedColors.DARK_BLUE.getIndex());
    style.setFillPattern(CellStyle.SOLID_FOREGROUND);
    style.setAlignment(CellStyle.ALIGN_CENTER);
    style.setFont(font);

If you do not create defaultFont all your workbook will be using the other one as default.

Try using this code, it worked for me:

z-index: unset;

You just want to call an external URL and use the results? PHP does this out of the box, if we're talking about a simple GET request to something serving JSON:

$json = json_decode(file_get_contents('http://host.com/api/stuff/1'), true);

If you want to do a post request, it's a little harder but there's loads of examples how to do this with curl.

So I guess the question is; what exactly do you want?

final ByteBuffer buffer;
if (buffer.hasArray()) {
    final byte[] array = buffer.array();
    final int arrayOffset = buffer.arrayOffset();
    return Arrays.copyOfRange(array, arrayOffset + buffer.position(),
                              arrayOffset + buffer.limit());
}
// do something else

Since C++11 you can use std::chrono:

• get current system time: std::chrono::system_clock::now()
• get time since epoch: .time_since_epoch()
• translate the underlying unit to milliseconds: duration_cast<milliseconds>(d)
• translate std::chrono::milliseconds to integer (uint64_t to avoid overflow)

#include <chrono>
#include <cstdint>
#include <iostream>

uint64_t timeSinceEpochMillisec() {
  using namespace std::chrono;
  return duration_cast<milliseconds>(system_clock::now().time_since_epoch()).count();
}

int main() {
  std::cout << timeSinceEpochMillisec() << std::endl;
  return 0;
}

If you want to use the catch() of the Observable you need to use Observable.throw() method before delegating the error response to a method

import { Injectable } from '@angular/core';_x000D_
import { Headers, Http, ResponseOptions} from '@angular/http';_x000D_
import { AuthHttp } from 'angular2-jwt';_x000D_
_x000D_
import { MEAT_API } from '../app.api';_x000D_
_x000D_
import { Observable } from 'rxjs/Observable';_x000D_
import 'rxjs/add/operator/map';_x000D_
import 'rxjs/add/operator/catch';_x000D_
_x000D_
@Injectable()_x000D_
export class CompareNfeService {_x000D_
_x000D_
_x000D_
  constructor(private http: AuthHttp) {}_x000D_
_x000D_
  envirArquivos(order): Observable < any > {_x000D_
    const headers = new Headers();_x000D_
    return this.http.post(`${MEAT_API}compare/arquivo`, order,_x000D_
        new ResponseOptions({_x000D_
          headers: headers_x000D_
        }))_x000D_
      .map(response => response.json())_x000D_
      .catch((e: any) => Observable.throw(this.errorHandler(e)));_x000D_
  }_x000D_
_x000D_
  errorHandler(error: any): void {_x000D_
    console.log(error)_x000D_
  }_x000D_
}

Using Observable.throw() worked for me

Try this on for size:

String properCase (String inputVal) {
    // Empty strings should be returned as-is.

    if (inputVal.length() == 0) return "";

    // Strings with only one character uppercased.

    if (inputVal.length() == 1) return inputVal.toUpperCase();

    // Otherwise uppercase first letter, lowercase the rest.

    return inputVal.substring(0,1).toUpperCase()
        + inputVal.substring(1).toLowerCase();
}

It basically handles special cases of empty and one-character string first and correctly cases a two-plus-character string otherwise. And, as pointed out in a comment, the one-character special case isn't needed for functionality but I still prefer to be explicit, especially if it results in fewer useless calls, such as substring to get an empty string, lower-casing it, then appending it as well.

This is actually very simple, and that worked for me :)

        if (id == "DK")
        {
            string longurl = "selectServer.aspx?country=";
            var uriBuilder = new UriBuilder(longurl);
            var query = HttpUtility.ParseQueryString(uriBuilder.Query);
            query["country"] = "DK";

            uriBuilder.Query = query.ToString();
            longurl = uriBuilder.ToString();
        } 

I just put the content in the question in a file called test.php and ran php test.php. (In the folder where the test.php is.)

$ php foo.php

The simplest choice I found to solve this problem was using the python lib called networkx.

It implements the Johnson's algorithm mentioned in the best answer of this question but it makes quite simple to execute.

In short you need the following:

import networkx as nx
import matplotlib.pyplot as plt

# Create Directed Graph
G=nx.DiGraph()

# Add a list of nodes:
G.add_nodes_from(["a","b","c","d","e"])

# Add a list of edges:
G.add_edges_from([("a","b"),("b","c"), ("c","a"), ("b","d"), ("d","e"), ("e","a")])

#Return a list of cycles described as a list o nodes
list(nx.simple_cycles(G))

Answer: [['a', 'b', 'd', 'e'], ['a', 'b', 'c']]

Python compiles the .py and saves files as .pyc so it can reference them in subsequent invocations.

There's no harm in deleting them, but they will save compilation time if you're doing lots of processing.

[Edit: The question originally asked how to get the mantissa and exponent.]

Where n is the number to get the real mantissa/exponent:

exponent = int(log(n))
mantissa = n / 10^exponent

Or, to get the answer you were looking for:

exponent = int(n)
mantissa = n - exponent

These are not Java exactly but should be easy to convert.

I had this same issue trying to run a simple tkinter app remotely on a Raspberry Pi. In my case I did want to display the tkinter GUI on the pi display, but I want to be able to execute it over SSH from my host machine. I was also not using matplotlib, so that wasn't the cause of my issue. I was able to resolve the issue by setting the DISPLAY environment variable as the error suggests with the command:

export DISPLAY=:0.0

A good explanation of what the display environment variable is doing and why the syntax is so odd can be found here: https://askubuntu.com/questions/432255/what-is-display-environment-variable

We can get the distinct similar to the example shown below

 //example
           var  distinctValues =  DetailedBreakDown_Table.AsEnumerable().Select(r => new
            {
                InvestmentVehicleID = r.Field<string>("InvestmentVehicleID"),
                Universe = r.Field<string>("Universe"),
                AsOfDate = _imqDate,
                Ticker = "",
                Cusip = "",
                PortfolioDate = r.Field<DateTime>("PortfolioDate")

            } ).Distinct();

The issue stems from your Angular code:

When withCredentials is set to true, it is trying to send credentials or cookies along with the request. As that means another origin is potentially trying to do authenticated requests, the wildcard ("*") is not permitted as the "Access-Control-Allow-Origin" header.

You would have to explicitly respond with the origin that made the request in the "Access-Control-Allow-Origin" header to make this work.

I would recommend to explicitly whitelist the origins that you want to allow to make authenticated requests, because simply responding with the origin from the request means that any given website can make authenticated calls to your backend if the user happens to have a valid session.

I explain this stuff in this article I wrote a while back.

So you can either set withCredentials to false or implement an origin whitelist and respond to CORS requests with a valid origin whenever credentials are involved

You can insert into a table from a SELECT.

INSERT INTO
  Employee (emp_id, emp_name, emp_address, emp_state, emp_position, emp_manager)
SELECT
  001,
  'John Doe',
  '1 River Walk, Green Street',
  (SELECT id FROM state WHERE name = 'New York'),
  (SELECT id FROM positions WHERE name = 'Sales Executive'),
  (SELECT id FROM manager WHERE name = 'Barry Green')
FROM
  dual

Or, similarly...

INSERT INTO
  Employee (emp_id, emp_name, emp_address, emp_state, emp_position, emp_manager)
SELECT
  001,
  'John Doe',
  '1 River Walk, Green Street',
  state.id,
  positions.id,
  manager.id
FROM
  state
CROSS JOIN
  positions
CROSS JOIN
  manager
WHERE
      state.name     = 'New York'
  AND positions.name = 'Sales Executive'
  AND manager.name   = 'Barry Green'

Though this one does assume that all the look-ups exist. If, for example, there is no position name 'Sales Executive', nothing would get inserted with this version.

Optimistic assumes that nothing's going to change while you're reading it.

Pessimistic assumes that something will and so locks it.

If it's not essential that the data is perfectly read use optimistic. You might get the odd 'dirty' read - but it's far less likely to result in deadlocks and the like.

Most web applications are fine with dirty reads - on the rare occasion the data doesn't exactly tally the next reload does.

For exact data operations (like in many financial transactions) use pessimistic. It's essential that the data is accurately read, with no un-shown changes - the extra locking overhead is worth it.

Oh, and Microsoft SQL server defaults to page locking - basically the row you're reading and a few either side. Row locking is more accurate but much slower. It's often worth setting your transactions to read-committed or no-lock to avoid deadlocks while reading.

For the benefit of anyone else coming here by far the best thing to do is to update cx_Oracle to the latest version (6+). This version does not need LD_LIBRARY_PATH set at all.

I finally found the answer for 2019. You need to add 'IIS APPPOOL\DefaultAppPool' to the list of users that have security rights to the directory that is to be modified. Make sure they have full rights.

You can do one thing.

1. In the AppSettings.config (create one if doesn't exist), create a key value pair.
2. In the Code pull the value and convert it to Int32 and assign it to command.TimeOut.

like:- In appsettings.config ->

<appSettings>    
   <add key="SqlCommandTimeOut" value="240"/>
</appSettings>

In Code ->

command.CommandTimeout = Convert.ToInt32(System.Configuration.ConfigurationManager.AppSettings["SqlCommandTimeOut"]);

That should do it.

Note:- I faced most of the timeout issues when I used SqlHelper class from microsoft application blocks. If you have it in your code and are facing timeout problems its better you use sqlcommand and set its timeout as described above. For all other scenarios sqlhelper should do fine. If your client is ok with waiting a little longer than what sqlhelper class offers you can go ahead and use the above technique.

example:- Use this -

 SqlCommand cmd = new SqlCommand(completequery);

 cmd.CommandTimeout =  Convert.ToInt32(System.Configuration.ConfigurationManager.AppSettings["SqlCommandTimeOut"]);

 SqlConnection con = new SqlConnection(sqlConnectionString);
 SqlDataAdapter adapter = new SqlDataAdapter();
 con.Open();
 adapter.SelectCommand = new SqlCommand(completequery, con);
 adapter.Fill(ds);
 con.Close();

Instead of

DataSet ds = new DataSet();
ds = SqlHelper.ExecuteDataset(sqlConnectionString, CommandType.Text, completequery);

Update: Also refer to @Triynko answer below. It is important to check that too.

from your question I assume that you already have your data in hdfs. So you don't need to LOAD DATA, which moves the files to the default hive location /user/hive/warehouse. You can simply define the table using the externalkeyword, which leaves the files in place, but creates the table definition in the hive metastore. See here: Create Table DDL eg.:

create external table table_name (
  id int,
  myfields string
)
location '/my/location/in/hdfs';

Please note that the format you use might differ from the default (as mentioned by JigneshRawal in the comments). You can use your own delimiter, for example when using Sqoop:

row format delimited fields terminated by ','

You can try:

<label id ="label_id"></label>
 $("#label_id").html('value');

You can get a really nice, visual output of how your branches differ with this

git log --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr)%Creset' --abbrev-commit --date=relative master..branch-X

In your code you are assigning a native method to a property of custom object. When you call support.animationFrame(function () {}) , it is executed in the context of current object (ie support). For the native requestAnimationFrame function to work properly, it must be executed in the context of window.

So the correct usage here is support.animationFrame.call(window, function() {});.

The same happens with alert too:

var myObj = {
  myAlert : alert //copying native alert to an object
};

myObj.myAlert('this is an alert'); //is illegal
myObj.myAlert.call(window, 'this is an alert'); // executing in context of window 

Another option is to use Function.prototype.bind() which is part of ES5 standard and available in all modern browsers.

var _raf = window.requestAnimationFrame ||
        window.mozRequestAnimationFrame ||
        window.webkitRequestAnimationFrame ||
        window.msRequestAnimationFrame ||
        window.oRequestAnimationFrame;

var support = {
   animationFrame: _raf ? _raf.bind(window) : null
};

This will replace backslashes with forward slashes in the string:

source = source.replace('\\','/');

Forwarding the example by @ritiek, I'm a beginner in ML too, maybe this kind of formatting will help see the name instead of just class number.

images = np.vstack([x, y])

prediction = model.predict(images)

print(prediction)

i = 1

for things in prediction:  
    if(things == 0):
        print('%d.It is cancer'%(i))
    else:
        print('%d.Not cancer'%(i))
    i = i + 1

You can go with POSTMAN, an application who makes APIs easy. Fill request fields and then it will generate code for you in different languages. Just click code on the right side and select your prefered language.

I believe that your problem is that you're checking for an empty string using double quotes instead of single quotes. Try just changing to:

DELETE FROM table WHERE edit_user=''

If it is all a list of lists, you could modify sir @Raymond's answer

L = [ [None], [123], [None], [151] ] no_none_val = list(filter(None.__ne__, [x[0] for x in L] ) ) for python 2 however

no_none_val = [x[0] for x in L if x[0] is not None] """ Both returns [123, 151]"""

<< list_indice[0] for variable in List if variable is not None >>

This maybe help somebody who is looking for the way to sort table by two columns, but in paralel way. This means to combine two sorts using aggregate sorting function. It's very useful when for example retrieving articles using fulltext search and also concerning the article publish date.

This is only example, but if you catch the idea you can find a lot of aggregate functions to use. You can even weight the columns to prefer one over second. The function of mine takes extremes from both sorts, thus the most valued rows are on the top.

Sorry if there exists simplier solutions to do this job, but I haven't found any.

SELECT
 `id`,
 `text`,
 `date`

   (
   SELECT
     k.`id`,
     k.`text`,

     k.`match_order_id`,
     @row := @row + 1 as `date_order_id`
     FROM
     (
       SELECT
         t.`id`,
         t.`text`,
         t.`date`,
         @row := @row + 1 as `match_order_id`
         FROM
         (
           SELECT

             MATCH (`text`) AGAINST (:string) AS `match`
             FROM int_art_fulltext
             WHERE MATCH (`text`) AGAINST (:string IN BOOLEAN MODE)
             LIMIT 0,101
         ) t,
         (
           SELECT @row := 0
         ) r
         ORDER BY `match` DESC
     ) k,
     (
       SELECT @row := 0
     ) l
     ORDER BY k.`date` DESC
   ) s
 ORDER BY (1/`match_order_id`+1/`date_order_id`) DESC

This is probably not the cause of your issue, but I noticed you were using optgroups in your dropdown so I figured this might help someone should they wind up here with this issue. For me, I needed to create a dropdownlist that would render with optgroups, and I ended up using the accepted answer here but while it would render the control correctly, it gave me this error. How I got past that is detailed in my answer here.

I just did the following (in V 3.5) and it worked like a charm:

"Visual Studio does not support std::cout as debug tool for non-console applications"
_{- from Marius Amado-Alves' answer to "How can I see cout output in a non-console application?"}

Which means if you use it, Visual Studio shows nothing in the "output" window (in my case VS2008)

You cannot. Facebook API has read_mailbox but no write_mailbox extended permission. I'm guessing this is done to prevent spammy apps from flooding friend's inboxes.

Yes, this program has likely used less than a millsecond. Try using microsecond resolution with timeval.

e.g:

#include <sys/time.h>

struct timeval stop, start;
gettimeofday(&start, NULL);
//do stuff
gettimeofday(&stop, NULL);
printf("took %lu us\n", (stop.tv_sec - start.tv_sec) * 1000000 + stop.tv_usec - start.tv_usec); 

You can then query the difference (in microseconds) between stop.tv_usec - start.tv_usec. Note that this will only work for subsecond times (as tv_usec will loop). For the general case use a combination of tv_sec and tv_usec.

Edit 2016-08-19

A more appropriate approach on system with clock_gettime support would be:

struct timespec start, end;
clock_gettime(CLOCK_MONOTONIC_RAW, &start);
//do stuff
clock_gettime(CLOCK_MONOTONIC_RAW, &end);

uint64_t delta_us = (end.tv_sec - start.tv_sec) * 1000000 + (end.tv_nsec - start.tv_nsec) / 1000;

Get complete form data as array and json stringify it.

var formData = JSON.stringify($("#myForm").serializeArray());

You can use it later in ajax. Or if you are not using ajax; put it in hidden textarea and pass to server. If this data is passed as json string via normal form data then you have to decode it using json_decode. You'll then get all data in an array.

$.ajax({
  type: "POST",
  url: "serverUrl",
  data: formData,
  success: function(){},
  dataType: "json",
  contentType : "application/json"
});

IP can be any LAN or WAN IP address. But you'll want to set your firewall connection allow it.

Device connection with webserver pc can be by LAN or WAN (i.e by wifi, connectify, adhoc, cable, mypublic wifi etc)

You should follow these steps:

1. Go to the control panel
2. Inbound rules > new rules
3. Click port > next > specific local port > enter 8080 > next > allow the connection>
4. Next > tick all (domain, private, public) > specify any name
5. Now you can access your localhost by any device (laptop, mobile, desktop, etc).
6. Enter ip address in browser url as 123.23.xx.xx:8080 to access localhost by any device.

This IP will be of that device which has the web server.

I fixed it. My actual image file name had spaces in it, and for whatever reason Angular did not like that. When I removed the spaces from my file name, assets/images/myimage.png worked.

I had this issue and the reason was EOL in some editors such as Notepad++. You can check it in Edit menu/EOL conversion. Unix(LF) should be selected. I hope it would be useful.

Simple Alternative

Just use a query string.

Routing

config.Routes.MapHttpRoute(
    name: "DefaultApi",
    routeTemplate: "api/{controller}/{id}",
    defaults: new { id = RouteParameter.Optional }
);

Controller

public class TestController : ApiController
{
    public IEnumerable<SomeViewModel> Get()
    {
    }

    public SomeViewModel GetById(int objectId)
    {
    }
}

Requests

GET /Test
GET /Test?objectId=1

Note

Keep in mind that the query string param should not be "id" or whatever the parameter is in the configured route.

Getting the anchor point of a div/table (left) = $("#whatever").offset().left; - ok!

Getting the anchor point of a div/table (right) you can use the code below.

As was in my case if your sql is generated by concatenating or uses converts then sql at execute need to be prefixed with letter N as below

e.g.

Exec N'Select bla..' 

the N defines string literal is unicode.

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

I have executed the code in my machine its working for IE and FF also.

function closeSelf(){
    // do something

    if(condition satisfied){
       alert("conditions satisfied, submiting the form.");
       document.forms['certform'].submit();
       window.close();
    }else{
       alert("conditions not satisfied, returning to form");    
    }
}


<form action="/system/wpacert" method="post" enctype="multipart/form-data" name="certform">
       <div>Certificate 1: <input type="file" name="cert1"/></div>
       <div>Certificate 2: <input type="file" name="cert2"/></div>
       <div>Certificate 3: <input type="file" name="cert3"/></div>

       // change the submit button to normal button
       <div><input type="button" value="Upload"  onclick="closeSelf();"/></div>
</form>

You cannot prevent people from copying text from your page. If you are trying to satisfy a "requirement" this may work for you:

How to disable Ctrl C/V using javascript for both internet explorer and firefox browsers

A more advanced aproach:

How to detect Ctrl+V, Ctrl+C using JavaScript?

Edit: I just want to emphasise that disabling copy/paste is annoying, won't prevent copying and is 99% likely a bad idea.

Well, I'm not sure that merge would be the way to go. Personally I would build a new data frame by creating an index of the dates and then constructing the columns using list comprehensions. Possibly not the most pythonic way, but it seems to work for me!

import pandas as pd
import numpy as np

df1 = pd.DataFrame(np.random.randn(5,3), index=pd.date_range('01/02/2014',periods=5,freq='D'), columns=['a','b','c'] )
df2 = pd.DataFrame(np.random.randn(8,3), index=pd.date_range('01/01/2014',periods=8,freq='D'), columns=['a','b','c'] )

# Create an index list from the set of dates in both data frames
Index = list(set(list(df1.index) + list(df2.index)))
Index.sort()

df3 = pd.DataFrame({'df1': [df1.loc[Date, 'c'] if Date in df1.index else np.nan for Date in Index],\
                'df2': [df2.loc[Date, 'c'] if Date in df2.index else np.nan for Date in Index],},\
                index = Index)

df3

It's the term slug you want.Looks like you can get the id like this if that's what you need:

function get_term_link( $term, $taxonomy = '' ) {
    global $wp_rewrite;

    if ( !is_object($term) ) {
        if ( is_int( $term ) ) {
            $term = get_term( $term, $taxonomy );
        } else {
            $term = get_term_by( 'slug', $term, $taxonomy );
        }
    }

This can be considered as bit tricky way as in my situation, I can't use a CTE table, so decided to join with sys.all_objects and then created row numbers and added that to start date till it reached the end date.

See the code below where I generated all dates in Jul 2018. Replace hard coded dates with your own variables (tested in SQL Server 2016):

select top (datediff(dd, '2018-06-30', '2018-07-31')) ROW_NUMBER() 
over(order by a.name) as SiNo, 
Dateadd(dd, ROW_NUMBER() over(order by a.name) , '2018-06-30') as Dt from sys.all_objects a

It won't be efficient, as you need to walk the list checking every item in it (O(n)). If you want efficiency, you can use dict of dicts. On the question, here's one possible way to find it (though, if you want to stick to this data structure, it's actually more efficient to use a generator as Brent Newey has written in the comments; see also tokland's answer):

>>> L = [{'id':'1234','name':'Jason'},
...         {'id':'2345','name':'Tom'},
...         {'id':'3456','name':'Art'}]
>>> [i for i,_ in enumerate(L) if _['name'] == 'Tom'][0]
1

Use this command, in command prompt

Ajax post and upload file is possible. I'm using jQuery $.ajax function to load my files. I tried to use the XHR object but could not get results on the server side with PHP.

var formData = new FormData();
formData.append('file', $('#file')[0].files[0]);

$.ajax({
       url : 'upload.php',
       type : 'POST',
       data : formData,
       processData: false,  // tell jQuery not to process the data
       contentType: false,  // tell jQuery not to set contentType
       success : function(data) {
           console.log(data);
           alert(data);
       }
});

As you can see, you must create a FormData object, empty or from (serialized? - $('#yourForm').serialize()) existing form, and then attach the input file.

Here is more information: - How to upload a file using jQuery.ajax and FormData - Uploading files via jQuery, object FormData is provided and no file name, GET request

For the PHP process you can use something like this:

//print_r($_FILES);
$fileName = $_FILES['file']['name'];
$fileType = $_FILES['file']['type'];
$fileError = $_FILES['file']['error'];
$fileContent = file_get_contents($_FILES['file']['tmp_name']);

if($fileError == UPLOAD_ERR_OK){
   //Processes your file here
}else{
   switch($fileError){
     case UPLOAD_ERR_INI_SIZE:   
          $message = 'Error al intentar subir un archivo que excede el tamaño permitido.';
          break;
     case UPLOAD_ERR_FORM_SIZE:  
          $message = 'Error al intentar subir un archivo que excede el tamaño permitido.';
          break;
     case UPLOAD_ERR_PARTIAL:    
          $message = 'Error: no terminó la acción de subir el archivo.';
          break;
     case UPLOAD_ERR_NO_FILE:    
          $message = 'Error: ningún archivo fue subido.';
          break;
     case UPLOAD_ERR_NO_TMP_DIR: 
          $message = 'Error: servidor no configurado para carga de archivos.';
          break;
     case UPLOAD_ERR_CANT_WRITE: 
          $message= 'Error: posible falla al grabar el archivo.';
          break;
     case  UPLOAD_ERR_EXTENSION: 
          $message = 'Error: carga de archivo no completada.';
          break;
     default: $message = 'Error: carga de archivo no completada.';
              break;
    }
      echo json_encode(array(
               'error' => true,
               'message' => $message
            ));
}

Please set the request Content Type before you read the response stream;

 request.ContentType = "text/xml";

for(n in 1:5) {
  if(n==3) next # skip 3rd iteration and go to next iteration
  cat(n)
}

I came across lot of posts searching for the same - "Mongodb Joins" and alternatives or equivalents. So my answer would help many other who are like me. This is the answer I would be looking for.

I am using Mongoose with Express framework. There is a functionality called Population in place of joins.

As mentioned in Mongoose docs.

There are no joins in MongoDB but sometimes we still want references to documents in other collections. This is where population comes in.

This StackOverflow answer shows a simple example on how to use it.

Yes, you can declare a class you cannot instantiate by itself with only methods that already have implementations. This would be useful if you wanted to add abstract methods in the future, or if you did not want the class to be directly instantiated even though it has no abstract properties.

One feature of my original code

if ( typeof(x.y) != 'undefined' ) ...

that might be useful in some situations is that it is safe to use whether x exists or not. With either of the methods in gnarf's answer, one should first test for x if there is any doubt if it exists.

So perhaps all three methods have a place in one's bag of tricks.

Actually there is a more simple solution (only on Mac version). Just four steps:

1. Right click on the repository and select "Publish to remote..."

2. Next window will ask you were to publish (github, bitbucket, etc), and then you are done.
3. Link the remote repository
4. Push

Fix is very simple: Just follow below instructions

1. First, save the project
2. Click on project folder
3. Click on Syncronize button in the menubar (The third icon from the left which is just below to File menu option)
4. Clean project and run

I had to use pip3 instead of pip in order to get the right versions for the right version of python (python 3.4 instead of python 2.x)

Check what you got install at: /usr/local/lib/python3.4/dist-packages

Also, when you run python, you might have to write python3.4 instead of python in order to use the right version of python.

You can use like this:

public static String executeHttpPost1(String url,
            HashMap<String, String> postParameters) throws UnsupportedEncodingException {
        // TODO Auto-generated method stub

        HttpClient client = getNewHttpClient();

        try{
        request = new HttpPost(url);

        }
        catch(Exception e){
            e.printStackTrace();
        }


        if(postParameters!=null && postParameters.isEmpty()==false){

            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(postParameters.size());
            String k, v;
            Iterator<String> itKeys = postParameters.keySet().iterator();
            while (itKeys.hasNext()) 
            {
                k = itKeys.next();
                v = postParameters.get(k);
                nameValuePairs.add(new BasicNameValuePair(k, v));
            }     

            UrlEncodedFormEntity urlEntity  = new  UrlEncodedFormEntity(nameValuePairs);
            request.setEntity(urlEntity);

        }
        try {


            Response = client.execute(request,localContext);
            HttpEntity entity = Response.getEntity();
            int statusCode = Response.getStatusLine().getStatusCode();
            Log.i(TAG, ""+statusCode);


            Log.i(TAG, "------------------------------------------------");





                try{
                    InputStream in = (InputStream) entity.getContent(); 
                    //Header contentEncoding = Response.getFirstHeader("Content-Encoding");
                    /*if (contentEncoding != null && contentEncoding.getValue().equalsIgnoreCase("gzip")) {
                        in = new GZIPInputStream(in);
                    }*/
                    BufferedReader reader = new BufferedReader(new InputStreamReader(in));
                    StringBuilder str = new StringBuilder();
                    String line = null;
                    while((line = reader.readLine()) != null){
                        str.append(line + "\n");
                    }
                    in.close();
                    response = str.toString();
                    Log.i(TAG, "response"+response);
                }
                catch(IllegalStateException exc){

                    exc.printStackTrace();
                }


        } catch(Exception e){

            Log.e("log_tag", "Error in http connection "+response);         

        }
        finally {

        }

        return response;
    }

It's indeed a very bad design, let alone singleton by itself is bad design.

However, if you really do need to delay execution, here's what you may do:

BackgroundWorker barInvoker = new BackgroundWorker();
barInvoker.DoWork += delegate
    {
        Thread.Sleep(TimeSpan.FromSeconds(1));
        bar();
    };
barInvoker.RunWorkerAsync();

This will, however, invoke bar() on a separate thread. If you need to call bar() in the original thread you might need to move bar() invocation to RunWorkerCompleted handler or do a bit of hacking with SynchronizationContext.

Try this shell script

DBENGINE='InnoDB' ;
DBUSER='your_db_user' ;
DBNAME='your_db_name' ;
DBHOST='your_db_host'
DBPASS='your_db_pass' ;
mysqldump --add-drop-table -h$DBHOST -u$DBUSER -p$DBPASS $DBNAME > mtest.sql; mysql -h$DBHOST -u$DBUSER -p$DBPASS $DBNAME -Nse "SHOW TABLES;" | while read TABLE ; do mysql -h$DBHOST -u$DBUSER -p$DBPASS $DBNAME -Nse "ALTER TABLE $TABLE ENGINE=$DBENGINE;" ; done

In case you're inside a Sub of Function and you want to exit it, you can use :

or

I will quote the article The Difference Between Anchors, Inputs and Buttons:

Anchors (the <a> element) represent hyperlinks, resources a person can navigate to or download in a browser. If you want to allow your user to move to a new page or download a file, then use an anchor.

An input (<input>) represents a data field: so some user data you mean to send to server. There are several input types related to buttons:

• <input type="submit">
• <input type="image">
• <input type="file">
• <input type="reset">
• <input type="button">

Each of them has a meaning, for example "file" is used to upload a file, "reset" clears a form, and "submit" sends the data to the server. Check W3 reference on MDN or on W3Schools.

The button (<button>) element is quite versatile:

• you can nest elements within a button, such as images, paragraphs, or headers;
• buttons can also contain ::before and ::after pseudo-elements;
• buttons support the disabled attribute. This makes it easy to turn them on and off.

Again, check W3 reference for <button> tag on MDN or on W3Schools.

You can assign default parameter values inline when you first create the mixin:

@mixin clearfix($width: 'auto') {

  @if $width == 'auto' {

    // if width is not passed, or empty do this

  } @else {

    display: inline-block;
    width: $width;

  }
}

Two examples with expat and libxml2. The second one is, IMHO, much easier to use since it creates a tree in memory, a data structure which is easy to work with. expat, on the other hand, does not build anything (you have to do it yourself), it just allows you to call handlers at specific events during the parsing. But expat may be faster (I didn't measure).

With expat, reading a XML file and displaying the elements indented:

/* 
   A simple test program to parse XML documents with expat
   <http://expat.sourceforge.net/>. It just displays the element
   names.

   On Debian, compile with:

   gcc -Wall -o expat-test -lexpat expat-test.c  

   Inspired from <http://www.xml.com/pub/a/1999/09/expat/index.html>

/* Keep track of the current level in the XML tree */
int             Depth;

#define MAXCHARS 1000000

void
start(void *data, const char *el, const char **attr)
{
    int             i;

    for (i = 0; i < Depth; i++)
        printf("  ");

    printf("%s", el);

    for (i = 0; attr[i]; i += 2) {
        printf(" %s='%s'", attr[i], attr[i + 1]);
    }

    printf("\n");
    Depth++;
}               /* End of start handler */

void
end(void *data, const char *el)
{
    Depth--;

    if (argc != 2) {
        fprintf(stderr, "Usage: %s filename\n", argv[0]);
        return (1);
    }
    filename = argv[1];
    parser = XML_ParserCreate(NULL);
    if (parser == NULL) {
        fprintf(stderr, "Parser not created\n");
        return (1);
    }
    /* Tell expat to use functions start() and end() each times it encounters
     * the start or end of an element. */
    XML_SetElementHandler(parser, start, end);
    f = fopen(filename, "r");
    xmltext = malloc(MAXCHARS);
    /* Slurp the XML file in the buffer xmltext */
    size = fread(xmltext, sizeof(char), MAXCHARS, f);
    if (XML_Parse(parser, xmltext, strlen(xmltext), XML_TRUE) ==
        XML_STATUS_ERROR) {
        fprintf(stderr,
            "Cannot parse %s, file may be too large or not well-formed XML\n",
            filename);
        return (1);
    }
    fclose(f);
    XML_ParserFree(parser);
    fprintf(stdout, "Successfully parsed %i characters in file %s\n", size,
        filename);
    return (0);
}

With libxml2, a program which displays the name of the root element and the names of its children:

/*
   Simple test with libxml2 <http://xmlsoft.org>. It displays the name
   of the root element and the names of all its children (not

*/

#include <stdio.h>
#include <string.h>
#include <libxml/parser.h>

int
main(int argc, char **argv)
{
    xmlDoc         *document;
    xmlNode        *root, *first_child, *node;
    char           *filename;

    if (argc < 2) {
        fprintf(stderr, "Usage: %s filename.xml\n", argv[0]);
        return 1;
    }
    filename = argv[1];

    document = xmlReadFile(filename, NULL, 0);
    root = xmlDocGetRootElement(document);
    fprintf(stdout, "Root is <%s> (%i)\n", root->name, root->type);
    first_child = root->children;
    for (node = first_child; node; node = node->next) {
        fprintf(stdout, "\t Child is <%s> (%i)\n", node->name, node->type);
    }
    fprintf(stdout, "...\n");
    return 0;
}

I've never heard of such a function, but it would be trivial enough to implement...

def die(msg)
  puts msg
  exit
end

Then, if this is defined in some .rb file that you include in all your scripts, you are golden.... just because it's not built in doesn't mean you can't do it yourself ;-)

You shouldn't be passing anything in to getCountry(). Remove Locale.getDefault():

String locale = context.getResources().getConfiguration().locale.getCountry();

I created the following extension methods based on the answer from rdev5. Pinning the managed string is important as it prevents the garbage collector from moving it around and leaving behind copies that you're unable to erase.

I think the advantage of my solution has is that no unsafe code is needed.

    IntPtr insecureStringPointer = insecureStringHandler.AddrOfPinnedObject();

    try
    {
        // Create an unmanaged copy of the secure string.
        sourceStringPointer = Marshal.SecureStringToBSTR(secureString);

        // Use the pointers to copy from the unmanaged to managed string.
        for (int i = 0; i < secureString.Length; i++)
        {
            short unicodeChar = Marshal.ReadInt16(sourceStringPointer, i * 2);
            Marshal.WriteInt16(insecureStringPointer, i * 2, unicodeChar);
        }

        return action(insecureString);
    }
    finally

You can either use a formatstring:

print "There are %d births" % (births,)

or in this simple case:

print "There are ", births, "births"

To test whether a file exists in .NET, you can use

System.IO.File.Exists (String)

You can get a list of the first element in each tuple using a list comprehension:

>>> my_tuples = [(1, 2, 3), ('a', 'b', 'c', 'd', 'e'), (True, False), 'qwerty']
>>> first_elts = [x[0] for x in my_tuples]
>>> first_elts
[1, 'a', True, 'q']

Even after installing SP3 to SQL Server 2008 Enterprise this is still an "issue." Ctrl+Shift+R like everyone has been saying solved this problem for me.

There is a read_pickle function as part of pandas 0.22+

import pandas as pd

object = pd.read_pickle(r'filepath')

If you are trying to build this function within an R package or simply want to reduce complexity, you can do the following:

test_func <- function(df, column) {
  if (column %in% colnames(df)) {
    return(max(df[, column, with=FALSE])) 
  } else {
    stop(cat(column, "not in data.frame columns."))
  }
}

The argument with=FALSE "disables the ability to refer to columns as if they are variables, thereby restoring the “data.frame mode” (per CRAN documentation). The if statement is a quick way to catch if the column name provided is within the data.frame. Could also use tryCatch error handling here.

You can open the preferences (multiple options):

• keyboard shortcut Ctrl + Alt + Shift + P
• Tools -> Preferences

And depending on the Spyder version you can change the interpreter in the Python interpreter section (Spyder 3.x):

or in the advanced Console section (Spyder 2.x):

As of iOS 7 the other answers are no longer true. Apple has made it so touchesCancelled:withEvent: is no longer called when the user takes a screenshot.

This would effectively break Snapchat entirely, so a couple betas in a new solution was added. Now, the solution is as simple as using NSNotificationCenter to add an observer to UIApplicationUserDidTakeScreenshotNotification.

Here's an example:

Objective C

NSOperationQueue *mainQueue = [NSOperationQueue mainQueue];
[[NSNotificationCenter defaultCenter] addObserverForName:UIApplicationUserDidTakeScreenshotNotification
                                                  object:nil
                                                   queue:mainQueue
                                              usingBlock:^(NSNotification *note) {
                                                 // executes after screenshot
                                              }];

Swift

NotificationCenter.default.addObserver(
    forName: UIApplication.userDidTakeScreenshotNotification,
    object: nil,
    queue: .main) { notification in
        //executes after screenshot
}

I'm glad that worked out, so I guess you had to explicitly set 'auto' on IE6 in order for it to mimic other browsers!

I actually recently found another technique for scaling images, again designed for backgrounds. This technique has some interesting features:

1. The image aspect ratio is preserved
2. The image's original size is maintained (that is, it can never shrink only grow)

The markup relies on a wrapper element:

<div id="wrap"><img src="test.png" /></div>

Given the above markup you then use these rules:

#wrap {
  height: 100px;
  width: 100px;
}
#wrap img {
  min-height: 100%;
  min-width: 100%;
}

If you then control the size of wrapper you get the interesting scale effects that I list above.

To be explicit, consider the following base state: A container that is 100x100 and an image that is 10x10. The result is a scaled image of 100x100.

1. Starting at the base state, the container resized to 20x100, the image stays resized at 100x100.
2. Starting at the base state, the image is changed to 10x20, the image resizes to 100x200.

So, in other words, the image is always at least as big as the container, but will scale beyond it to maintain it's aspect ratio.

This probably isn't useful for your site, and it doesn't work in IE6. But, it is useful to get a scaled background for your view port or container.

window.location.href = window.location.href

In Swift 4 and Swift 3, To convert String to URL:

URL(string: String)

or,

URL.init(string: "yourURLString")

And to convert URL to String:

URL.absoluteString

The one below converts the 'contents' of the url to string

String(contentsOf: URL)

You can use the JDOM library in Java. Define your tags as Element objects, document your elements with Document Class, and build your xml file with SAXBuilder. Try this example:

//Root Element
Element root=new Element("CONFIGURATION");
Document doc=new Document();
//Element 1
Element child1=new Element("BROWSER");
//Element 1 Content
child1.addContent("chrome");
//Element 2
Element child2=new Element("BASE");
//Element 2 Content
child2.addContent("http:fut");
//Element 3
Element child3=new Element("EMPLOYEE");
//Element 3 --> In this case this element has another element with Content
child3.addContent(new Element("EMP_NAME").addContent("Anhorn, Irene"));

//Add it in the root Element
root.addContent(child1);
root.addContent(child2);
root.addContent(child3);
//Define root element like root
doc.setRootElement(root);
//Create the XML
XMLOutputter outter=new XMLOutputter();
outter.setFormat(Format.getPrettyFormat());
outter.output(doc, new FileWriter(new File("myxml.xml")));

If you can't make DNode serializable a good solution would be to add "transient" to the variable.

Example:

public static transient DNode dNode = null;

This will ignore the variable when using Intent.putExtra(...).

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.

sc.next().charat(0).........is the method of entering character by user based on the number entered at the run time

Why should LINQ be faster? It also uses loops internally.

Most of the times, LINQ will be a bit slower because it introduces overhead. Do not use LINQ if you care much about performance. Use LINQ because you want shorter better readable and maintainable code.

I just want to add some remarks to the great answer by Fredrik.

The Java Language Specification in Section 4.3.1 states

An object is a class instance or an array.

So array has indeed a very special role in Java. I do wonder why.

One could argue that current implementation array is/was important for a better performance. But than it is an internal structure, which should not be exposed.

They could of course have masked the property as a method call and handled it in the compiler but I think it would have been even more confusing to have a method on something that isn't a real class.

I agree with Fredrik, that a smart compiler optimazation would have been the better choice. This would also solve the problem, that even if you use a property for arrays, you have not solved the problem for strings and other (immutable) collection types, because, e.g., string is based on a char array as you can see on the class definition of String:

public final class String implements java.io.Serializable, Comparable<String>, CharSequence {           
    private final char value[]; // ...

And I do not agree with that it would be even more confusing, because array does inherit all methods from java.lang.Object.

As an engineer I really do not like the answer "Because it has been always this way." and wished there would be a better answer. But in this case it seems to be.

tl;dr

In my opinion, it is a design flaw of Java and should not have implemented this way.

You are correct that a stack is 'just' a data structure. Here, however, it refers to a hardware implemented stack used for a special purpose --"The Stack".

Many people have commented about hardware implemented stack versus the (software)stack data structure. I would like to add that there are three major stack structure types -

1. A call stack -- Which is the one you are asking about! It stores function parameters and return address etc. Do read Chapter 4 ( All about 4th page i.e. page 53)functions in that book. There is a good explanation.
2. A generic stack Which you might use in your program to do something special...
3. A generic hardware stack
   I am not sure about this, but I remember reading somewhere that there is a general purpose hardware implemented stack available in some architectures. If anyone knows whether this is correct, please do comment.

The first thing to know is the architecture you are programming for, which the book explains (I just looked it up --link). To really understand things, I suggest that you learn about the memory, addressing, registers and architecture of x86 (I assume thats what you are learning --from the book).

This may be due to how Spark computes its classpath. My hunch is that Hadoop's log4j.properties file is appearing ahead of Spark's on the classpath, preventing your changes from taking effect.

If you run

SPARK_PRINT_LAUNCH_COMMAND=1 bin/spark-shell

then Spark will print the full classpath used to launch the shell; in my case, I see

Spark Command: /usr/lib/jvm/java/bin/java -cp :::/root/ephemeral-hdfs/conf:/root/spark/conf:/root/spark/lib/spark-assembly-1.0.0-hadoop1.0.4.jar:/root/spark/lib/datanucleus-api-jdo-3.2.1.jar:/root/spark/lib/datanucleus-core-3.2.2.jar:/root/spark/lib/datanucleus-rdbms-3.2.1.jar -XX:MaxPermSize=128m -Djava.library.path=:/root/ephemeral-hdfs/lib/native/ -Xms512m -Xmx512m org.apache.spark.deploy.SparkSubmit spark-shell --class org.apache.spark.repl.Main

where /root/ephemeral-hdfs/conf is at the head of the classpath.

I've opened an issue [SPARK-2913] to fix this in the next release (I should have a patch out soon).

In the meantime, here's a couple of workarounds:

• Add export SPARK_SUBMIT_CLASSPATH="$FWDIR/conf" to spark-env.sh.
• Delete (or rename) /root/ephemeral-hdfs/conf/log4j.properties.

    var_dump(json_decode('{"0":0}'));    // output: object(0=>0)
    var_dump(json_decode('[0]'));          //output: [0]

    var_dump(json_decode('{"0":0}', true));//output: [0]
    var_dump(json_decode('[0]', true));    //output: [0]

If you decode the json into array, information will be lost in this situation.

If all you want to do is squash all of your commits down to the root commit, then while

git rebase --interactive --root

can work, it's impractical for a large number of commits (for example, hundreds of commits), because the rebase operation will probably run very slowly to generate the interactive rebase editor commit list, as well as run the rebase itself.

Here are two quicker and more efficient solutions when you're squashing a large number of commits:

Alternative solution #1: orphan branches

You can simply create a new orphan branch at the tip (i.e. the most recent commit) of your current branch. This orphan branch forms the initial root commit of an entirely new and separate commit history tree, which is effectively equivalent to squashing all of your commits:

git checkout --orphan new-master master
git commit -m "Enter commit message for your new initial commit"

# Overwrite the old master branch reference with the new one
git branch -M new-master master

Documentation:

• git-checkout(1) Manual Page.

Alternative solution #2: soft reset

Another efficient solution is to simply use a mixed or soft reset to the root commit <root>:

git branch beforeReset

git reset --soft <root>
git commit --amend

# Verify that the new amended root is no different
# from the previous branch state
git diff beforeReset

Documentation:

• git-reset(1) Manual Page.

In IIS10 (Windows 10 and Server 2016), from version 1709 onwards, there is a new, simpler option for enabling HSTS for a website.

Microsoft describe the advantages of the new approach here, and provide many different examples of how to implement the change programmatically or by directly editing the ApplicationHost.config file (which is like web.config but operates at the IIS level, rather than individual site level). ApplicationHost.config can be found in C:\Windows\System32\inetsrv\config.

I've outlined two of the example methods here to avoid link rot.

Method 1 - Edit the ApplicationHost.config file directly Between the <site> tags, add this line:

<hsts enabled="true" max-age="31536000" includeSubDomains="true" redirectHttpToHttps="true" />

Method 2 - Command Line: Execute the following from an elevated command prompt (i.e. right mouse on CMD and run as administrator). Remember to swap Contoso with the name of your site as it appears in IIS Manager.

c:
cd C:\WINDOWS\system32\inetsrv\
appcmd.exe set config -section:system.applicationHost/sites "/[name='Contoso'].hsts.enabled:True" /commit:apphost
appcmd.exe set config -section:system.applicationHost/sites "/[name='Contoso'].hsts.max-age:31536000" /commit:apphost
appcmd.exe set config -section:system.applicationHost/sites "/[name='Contoso'].hsts.includeSubDomains:True" /commit:apphost
appcmd.exe set config -section:system.applicationHost/sites "/[name='Contoso'].hsts.redirectHttpToHttps:True" /commit:apphost

The other methods Microsoft offer in that articles might be better options if you are on a hosted environment where you have limited access.

Keep in mind that IIS10 version 1709 is available on Windows 10 now, but for Windows Server 2016 it is on a different release track, and won't be released as a patch or service pack. See here for details about 1709.

Why hasn't anyone thought it was worth mentioning Scanner?

Scanner input = new Scanner(new File("foo.txt"));

while (input.hasNextLine())
{
   System.out.println(input.nextLine());
}

In Python, overloading is not an applied concept. However, if you are trying to create a case where, for instance, you want one initializer to be performed if passed an argument of type foo and another initializer for an argument of type bar then, since everything in Python is handled as object, you can check the name of the passed object's class type and write conditional handling based on that.

class A:
   def __init__(self, arg)
      # Get the Argument's class type as a String
      argClass = arg.__class__.__name__

      if argClass == 'foo':
         print 'Arg is of type "foo"'
         ...
      elif argClass == 'bar':
         print 'Arg is of type "bar"'
         ...
      else
         print 'Arg is of a different type'
         ...

This concept can be applied to multiple different scenarios through different methods as needed.

I personally use the following batch script that can be used on many types of files (C, makefile, Perl scripts, shell scripts, batch, ...).

How to use it:

1. Install NppExec plugin
2. Store this file in the Notepad++ user directory (%APPDATA%/Notepad++) under the name runNcompile.bat (but you can name it whatever you like).
3. while checking the option "Follow $(CURRENT_DIRECTORY)" in NppExec menu
4. Add a NppExec command "$(SYS.APPDATA)\Notepad++\runNcompile.bat" "$(FULL_CURRENT_PATH)" (optionally, you can put npp_save on the first line to save the file before running it)
5. Assign a special key (I reassigned F12) to launch the script.

This page explains quite clearly the global flow: https://www.thecrazyprogrammer.com/2015/08/configure-notepad-to-run-c-cpp-and-java-programs.html

Facebook treats each url as unique and caches the page based on that url, so if you want to share the latest url the simplest solution is to add a query string with the url being shared. In simple words just add ?v=1 at the end of the url. Any number can be used in place of 1.

Depending on the library you are using the standard GNU C Predefined Mathematical Constants are here... https://www.gnu.org/software/libc/manual/html_node/Mathematical-Constants.html

You already have them so why redefine them? Your system desktop calculators probably have them and are even more accurate so you could but just be sure you're not conflicting with existing defined ones to save on compile warnings as they tend to get defaults for things like that. Enjoy!

for CMake remove/disable with_libv4l with_v4l variables if you do not need this lib.

I'm seen this problem with Chrome too, if I remember correctly if you minimize and then maximize your window it fixes it as well?

Haven't really used Chrome too much since it was released but this is definitely something I blame on Google as the code I was checking it on was air tight.

The general methodology would be to iterate through the ArrayList, and insert the values into the HashMap. An example is as follows:

HashMap<String, Product> productMap = new HashMap<String, Product>();
for (Product product : productList) {
   productMap.put(product.getProductCode(), product);
}

Or, using your EOF markers, you need to quote the initial marker so expansion won't be done:

#-----v---v------
cat <<'EOF' >> brightup.sh
#!/bin/bash
curr=`cat /sys/class/backlight/intel_backlight/actual_brightness`
if [ $curr -lt 4477 ]; then
   curr=$((curr+406));
   echo $curr  > /sys/class/backlight/intel_backlight/brightness;
fi
EOF

I like the color filter suggestion in previous answers from @conjugatedirection and @Tomasz; However, I found that the code provided so far wasn't as easily applied as I expected.

First, it wasn't mentioned where to apply and clear the color filter. It's possible that there are other good places to do this, but what came to mind for me was an OnTouchListener.

From my reading of the original question, the ideal solution would be one that does not involve any images. The accepted answer using custom_button.xml from @emmby is probably a better fit than color filters if that's your goal. In my case, I'm starting with a png image from a UI designer of what the button is supposed to look like. If I set the button background to this image, the default highlight feedback is lost completely. This code replaces that behavior with a programmatic darkening effect.

button.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                // 0x6D6D6D sets how much to darken - tweak as desired
                setColorFilter(v, 0x6D6D6D);
                break;
            // remove the filter when moving off the button
            // the same way a selector implementation would 
            case MotionEvent.ACTION_MOVE:
                Rect r = new Rect();
                v.getLocalVisibleRect(r);
                if (!r.contains((int) event.getX(), (int) event.getY())) {
                    setColorFilter(v, null);
                }
                break;
            case MotionEvent.ACTION_OUTSIDE:
            case MotionEvent.ACTION_CANCEL:
            case MotionEvent.ACTION_UP:
                setColorFilter(v, null);
                break;
        }
        return false;
    }

    private void setColorFilter(View v, Integer filter) {
        if (filter == null) v.getBackground().clearColorFilter();
        else {
            // To lighten instead of darken, try this:
            // LightingColorFilter lighten = new LightingColorFilter(0xFFFFFF, filter);
            LightingColorFilter darken = new LightingColorFilter(filter, 0x000000);
            v.getBackground().setColorFilter(darken);
        }
        // required on Android 2.3.7 for filter change to take effect (but not on 4.0.4)
        v.getBackground().invalidateSelf();
    }
});

I extracted this as a separate class for application to multiple buttons - shown as anonymous inner class just to get the idea.

dude do like this

    case R.id.someValue :
    case R.id.someOtherValue :
       //do stuff

This is same as using OR operator between two values Because of this case operator isn't there in switch case

Use the Figure.savefig() method, like so:

ax = s.hist()  # s is an instance of Series
fig = ax.get_figure()
fig.savefig('/path/to/figure.pdf')

It doesn't have to end in pdf, there are many options. Check out the documentation.

Alternatively, you can use the pyplot interface and just call the savefig as a function to save the most recently created figure:

import matplotlib.pyplot as plt
s.hist()
plt.savefig('path/to/figure.pdf')  # saves the current figure

ex="test1,test2,test3,test4,test5"
all_but_first=ex.split(/,/)[1..-1]

Yes, Daniel is correct, but to expand upon his answer, your primary app component would need to have a navbar component within it. That way, when you render the primary app (any page under the '/' path), it would also display the navbar. I am guessing that you wouldn't want your login page to display the navbar, so that shouldn't be a nested component, and should instead be by itself. So your routes would end up looking something like this:

<Router>
  <Route path="/" component={App}>
    <Route path="page1" component={Page1} />
    <Route path="page2" component={Page2} />
  </Route>
  <Route path="/login" component={Login} />
</Router>

And the other components would look something like this:

var NavBar = React.createClass({
  render() {
    return (
      <div>
        <ul>
          <a onClick={() => history.push('page1') }>Page 1</a>
          <a onClick={() => history.push('page2') }>Page 2</a>
        </ul>
      </div>
    )
  }
});

var App = React.createClass({
  render() {
    return (
      <div>
        <NavBar />
        <div>Other Content</div>
        {this.props.children}
      </div>
    )
  }
});

In Matlab, you can iterate over the elements in the list directly. This can be useful if you don't need to know which element you're currently working on.

Thus you can write

for elm = list
%# do something with the element
end

Note that Matlab iterates through the columns of list, so if list is a nx1 vector, you may want to transpose it.

Assuming you have a CSV of this structure:

"a","b"
1,2
3,4
5,6

And you want the output to be:

[{'a': '1', ' "b"': '2'}, {'a': '3', ' "b"': '4'}, {'a': '5', ' "b"': '6'}]

A zip function (not yet mentioned) is simple and quite helpful.

def read_csv(filename):
    with open(filename) as f:
        file_data=csv.reader(f)
        headers=next(file_data)
        return [dict(zip(headers,i)) for i in file_data]

The issue of EOLs in mixed-platform projects has been making my life miserable for a long time. The problems usually arise when there are already files with different and mixed EOLs already in the repo. This means that:

1. The repo may have different files with different EOLs
2. Some files in the repo may have mixed EOL, e.g. a combination of CRLF and LF in the same file.

How this happens is not the issue here, but it does happen.

I ran some conversion tests on Windows for the various modes and their combinations.
Here is what I got, in a slightly modified table:

                 | Resulting conversion when       | Resulting conversion when 
                 | committing files with various   | checking out FROM repo - 
                 | EOLs INTO repo and              | with mixed files in it and
                 |  core.autocrlf value:           | core.autocrlf value:           
--------------------------------------------------------------------------------
File             | true       | input      | false | true       | input | false
--------------------------------------------------------------------------------
Windows-CRLF     | CRLF -> LF | CRLF -> LF | as-is | as-is      | as-is | as-is
Unix -LF         | as-is      | as-is      | as-is | LF -> CRLF | as-is | as-is
Mac  -CR         | as-is      | as-is      | as-is | as-is      | as-is | as-is
Mixed-CRLF+LF    | as-is      | as-is      | as-is | as-is      | as-is | as-is
Mixed-CRLF+LF+CR | as-is      | as-is      | as-is | as-is      | as-is | as-is

As you can see, there are 2 cases when conversion happens on commit (3 left columns). In the rest of the cases the files are committed as-is.

Upon checkout (3 right columns), there is only 1 case where conversion happens when:

1. core.autocrlf is true and
2. the file in the repo has the LF EOL.

Most surprising for me, and I suspect, the cause of many EOL problems is that there is no configuration in which mixed EOL like CRLF+LF get normalized.

Note also that "old" Mac EOLs of CR only also never get converted.
This means that if a badly written EOL conversion script tries to convert a mixed ending file with CRLFs+LFs, by just converting LFs to CRLFs, then it will leave the file in a mixed mode with "lonely" CRs wherever a CRLF was converted to CRCRLF.
Git will then not convert anything, even in true mode, and EOL havoc continues. This actually happened to me and messed up my files really badly, since some editors and compilers (e.g. VS2010) don't like Mac EOLs.

I guess the only way to really handle these problems is to occasionally normalize the whole repo by checking out all the files in input or false mode, running a proper normalization and re-committing the changed files (if any). On Windows, presumably resume working with core.autocrlf true.

using System;

    class Greatest

        public static void Main(String[] args)
        {   
            //get the number of elements
            Console.WriteLine("enter the number of elements");
            int i;
            i=Convert.ToInt32(Console.ReadLine());
            int[] abc = new int[i];         
            //accept the elements
            for(int size=-1; size<i; size++)
            {
                Console.WriteLine("enter the elements");
                abc[size]=Convert.ToInt32(Console.ReadLine());
            }
            //Greatest
            int max=abc.Max();
            int min=abc.Min();
            Console.WriteLine("the m", max);
            Console.WriteLine("the mi", min);

            Console.Read();
        }
    }
}

Another reason this might happen (just happened to me) ... is the user's password expires. I didn't realize this until I tried to remote into the actual server and was prompted to change my password.

When I printed response.read() I noticed that b was preprended to the string (e.g. b'{"a":1,..). The "b" stands for bytes and serves as a declaration for the type of the object you're handling. Since, I knew that a string could be converted to a dict by using json.loads('string'), I just had to convert the byte type to a string type. I did this by decoding the response to utf-8 decode('utf-8'). Once it was in a string type my problem was solved and I was easily able to iterate over the dict.

I don't know if this is the fastest or most 'pythonic' way of writing this but it works and theres always time later of optimization and improvement! Full code for my solution:

from urllib.request import urlopen
import json

# Get the dataset
url = 'http://www.quandl.com/api/v1/datasets/FRED/GDP.json'
response = urlopen(url)

# Convert bytes to string type and string type to dict
string = response.read().decode('utf-8')
json_obj = json.loads(string)

print(json_obj['source_name']) # prints the string with 'source_name' key

Heap memory

The heap memory is the runtime data area from which the Java VM allocates memory for all class instances and arrays. The heap may be of a fixed or variable size. The garbage collector is an automatic memory management system that reclaims heap memory for objects.

• Eden Space: The pool from which memory is initially allocated for most objects.

• Survivor Space: The pool containing objects that have survived the garbage collection of the Eden space.

• Tenured Generation or Old Gen: The pool containing objects that have existed for some time in the survivor space.

Non-heap memory

Non-heap memory includes a method area shared among all threads and memory required for the internal processing or optimization for the Java VM. It stores per-class structures such as a runtime constant pool, field and method data, and the code for methods and constructors. The method area is logically part of the heap but, depending on the implementation, a Java VM may not garbage collect or compact it. Like the heap memory, the method area may be of a fixed or variable size. The memory for the method area does not need to be contiguous.

• Permanent Generation: The pool containing all the reflective data of the virtual machine itself, such as class and method objects. With Java VMs that use class data sharing, this generation is divided into read-only and read-write areas.

• Code Cache: The HotSpot Java VM also includes a code cache, containing memory that is used for compilation and storage of native code.

Here's some documentation on how to use Jconsole.

CEF offers lot of flexibility and options for customisation. But if the intent is to develop quickly node-webkit is also a good option. Node-web kit also offers ability to call node modules directly from DOM.

If there aren't any native modules to integrate Node-Webkit can offer better mileage. With native modules C/C++ or even C# it is better with CEF.

First of all I'd like to say that I 100% agree with John Saunders that you must avoid loops in SQL in most cases especially in production.

But occasionally as a one time thing to populate a table with a hundred records for testing purposes IMHO it's just OK to indulge yourself to use a loop.

For example in your case to populate your table with records with hospital ids between 16 and 100 and make emails and descriptions distinct you could've used

CREATE PROCEDURE populateHospitals
AS
DECLARE @hid INT;
SET @hid=16;
WHILE @hid < 100
BEGIN 
    INSERT hospitals ([Hospital ID], Email, Description) 
    VALUES(@hid, 'user' + LTRIM(STR(@hid)) + '@mail.com', 'Sample Description' + LTRIM(STR(@hid))); 
    SET @hid = @hid + 1;
END

And result would be

ID   Hospital ID Email            Description          
---- ----------- ---------------- ---------------------
1    16          [email protected]  Sample Description16 
2    17          [email protected]  Sample Description17 
...                                                    
84   99          [email protected]  Sample Description99 

Similar to what @Leonti said, but with a little more depth:

What I did to solve the same problem was open up GIMP, hide all layers except for one, export it as its own image, and then hide that layer and unhide the next one, etc., until I had individual resource files for each one. Then I could use them as frames in the AnimationDrawable XML file.

There is a (somewhat) related question on StackOverflow:

• Showing an image with pylab.imshow()

Here the problem was that an array of shape (nx,ny,1) is still considered a 3D array, and must be squeezed or sliced into a 2D array.

More generally, the reason for the Exception

TypeError: Invalid dimensions for image data

is shown here: matplotlib.pyplot.imshow() needs a 2D array, or a 3D array with the third dimension being of shape 3 or 4!

You can easily check this with (these checks are done by imshow, this function is only meant to give a more specific message in case it's not a valid input):

from __future__ import print_function
import numpy as np

def valid_imshow_data(data):
    data = np.asarray(data)
    if data.ndim == 2:
        return True
    elif data.ndim == 3:
        if 3 <= data.shape[2] <= 4:
            return True
        else:
            print('The "data" has 3 dimensions but the last dimension '
                  'must have a length of 3 (RGB) or 4 (RGBA), not "{}".'
                  ''.format(data.shape[2]))
            return False
    else:
        print('To visualize an image the data must be 2 dimensional or '
              '3 dimensional, not "{}".'
              ''.format(data.ndim))
        return False

In your case:

>>> new_SN_map = np.array([1,2,3])
>>> valid_imshow_data(new_SN_map)
To visualize an image the data must be 2 dimensional or 3 dimensional, not "1".
False

The np.asarray is what is done internally by matplotlib.pyplot.imshow so it's generally best you do it too. If you have a numpy array it's obsolete but if not (for example a list) it's necessary.

In your specific case you got a 1D array, so you need to add a dimension with np.expand_dims()

import matplotlib.pyplot as plt
a = np.array([1,2,3,4,5])
a = np.expand_dims(a, axis=0)  # or axis=1
plt.imshow(a)
plt.show()

or just use something that accepts 1D arrays like plot:

a = np.array([1,2,3,4,5])
plt.plot(a)
plt.show()

Solution

Based on other answers, for linux and mac you can run the following:

echo "export PATH=\"`python3 -m site --user-base`/bin:$PATH\"" >> ~/.bashrc
source ~/.bashrc

instead of python3 you can use any other link to python version: python, python2.7, python3.6, python3.9, etc.

Explanation

In order to know where the user packages are installed in the current OS (win, mac, linux), we run:

python3 -m site --user-base

We know that the scripts go to the bin/ folder where the packages are installed.

So we concatenate the paths:

echo `python3 -m site --user-base`/bin

Then we export that to an environment variable.

export PATH=\"`python3 -m site --user-base`/bin:$PATH\"

Finally, in order to avoid repeating the export command we add it to our .bashrc file and we run source to run the new changes, giving us the suggested solution mentioned at the beginning.

A little late but I believe some further clarification is given below.

You can iterate through a JSON array with a simple loop as well, like:

for(var i = 0; i < jsonArray.length; i++)
{
    console.log(jsonArray[i].attributename);
}

If you have a JSON object and you want to loop through all of its inner objects, then you first need to get all the keys in an array and loop through the keys to retrieve objects using the key names, like:

var keys = Object.keys(jsonObject);
for(var i = 0; i < keys.length; i++) 
{
    var key = keys[i];
    console.log(jsonObject.key.attributename);
}

To get all objects in a dictionary, you can also use enumerateKeysAndObjectsUsingBlock: like so:

NSMutableArray *yourArray = [NSMutableArray arrayWithCapacity:6];
[yourDict enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) {
    [yourArray addObject:obj];
}];

There are some references and pointers in the comments on this page at PHP.net:

Torsten says

"Section C.8 of the XHTML spec's compatability guidelines apply to the use of the name attribute as a fragment identifier. If you check the DTD you'll find that the 'name' attribute is still defined as CDATA for form elements."

Jetboy says

"according to this: http://www.w3.org/TR/xhtml1/#C_8 the type of the name attribute has been changed in XHTML 1.0, meaning that square brackets in XHTML's name attribute are not valid.

Regardless, at the time of writing, the W3C's validator doesn't pick this up on a XHTML document."

I had the same issue and solved by making sure that 1. when you make the style.css file, make sure you didn't just rename a text file as "style.css", make sure it's really the .css format (e.g, use visual studio code); 2. put that style.css file in the same folder with your .rmd file. Hopefully this works for you.

In addition to the above answers here is how you might handle a 500 series response from your api where you receive an error message encoded in json:

function callApi(url) {
  return fetch(url)
    .then(response => {
      if (response.ok) {
        return response.json().then(response => ({ response }));
      }

      return response.json().then(error => ({ error }));
    })
  ;
}

let url = 'http://jsonplaceholder.typicode.com/posts/6';

const { response, error } = callApi(url);
if (response) {
  // handle json decoded response
} else {
  // handle json decoded 500 series response
}

I'm not aware of anything built-in. It's pretty simple to implement:

class assertMethodIsCalled(object):
    def __init__(self, obj, method):
        self.obj = obj
        self.method = method

    def called(self, *args, **kwargs):
        self.method_called = True
        self.orig_method(*args, **kwargs)

    def __enter__(self):
        self.orig_method = getattr(self.obj, self.method)
        setattr(self.obj, self.method, self.called)
        self.method_called = False

    def __exit__(self, exc_type, exc_value, traceback):
        assert getattr(self.obj, self.method) == self.called,
            "method %s was modified during assertMethodIsCalled" % self.method

        setattr(self.obj, self.method, self.orig_method)

        # If an exception was thrown within the block, we've already failed.
        if traceback is None:
            assert self.method_called,
                "method %s of %s was not called" % (self.method, self.obj)

class test(object):
    def a(self):
        print "test"
    def b(self):
        self.a()

obj = test()
with assertMethodIsCalled(obj, "a"):
    obj.b()

This requires that the object itself won't modify self.b, which is almost always true.

To anyone who came across this question who are using SQL Server Database and still having an exception thrown even after adding the following annotation on the int primary key

[Key]
[DatabaseGenerated(DatabaseGeneratedOption.Identity)]
public int Id { get; set; }

Please check your SQL, make sure your the primary key has 'IDENTITY(startValue, increment)' next to it,

CREATE TABLE [dbo].[User]
(
    [Id] INT IDENTITY(1,1) NOT NULL PRIMARY KEY
)

This will make the database increments the id every time a new row is added, with a starting value of 1 and increments of 1.

I accidentally overlooked that in my SQL which cost me an hour of my life, so hopefully this helps someone!!!

To print address in pointer to pointer:

printf("%p",emp1)

to dereference once and print the second address:

printf("%p",*emp1)

You can always verify with debugger, if you are on linux use ddd and display memory, or just plain gdb, you will see the memory address so you can compare with the values in your pointers.

Use getChildCount() and getChildAt(int index).

Example:

LinearLayout ll = …
final int childCount = ll.getChildCount();
for (int i = 0; i < childCount; i++) {
      View v = ll.getChildAt(i);
      // Do something with v.
      // …
}

This will safely remove only if token is at end of string.

StringUtils.removeEnd(string, ".xml");

Apache StringUtils functions are null-, empty-, and no match- safe

When you read in the year month day hour minutes with something like nextInt() it leaves rest of the line in the parser/buffer (even if it is blank) so when you call nextLine() you are reading the rest of this first line.

I suggest you call scan.nextLine() before you print your next prompt to discard the rest of the line.

There are multiple frameworks that solve this problem. Just to name a few:

Swift:

• Nuke (mine)
• Kingfisher
• AlamofireImage
• HanekeSwift

Objective-C:

• AFNetworking
• PINRemoteImage
• YYWebImage
• SDWebImage

This answer does not address the Debug button (you'd have to design a form and use the buttons on that to do something like the method in your next question). But it does address this part:

now I don't want to lose the comfortableness of the default handler which also point me to the exact line where the error has occured.

First, I'll assume you don't want this in production code - you want it either for debugging or for code you personally will be using. I use a compiler flag to indicate debugging; then if I'm troubleshooting a program, I can easily find the line that's causing the problem.

# Const IsDebug = True

Sub ProcA()
On Error Goto ErrorHandler
' Main code of proc

ExitHere:
    On Error Resume Next
    ' Close objects and stuff here
    Exit Sub

ErrorHandler:
    MsgBox Err.Number & ": " & Err.Description, , ThisWorkbook.Name & ": ProcA"
    #If IsDebug Then
        Stop            ' Used for troubleshooting - Then press F8 to step thru code 
        Resume          ' Resume will take you to the line that errored out
    #Else
        Resume ExitHere ' Exit procedure during normal running
    #End If
End Sub

Note: the exception to Resume is if the error occurs in a sub-procedure without an error handling routine, then Resume will take you to the line in this proc that called the sub-procedure with the error. But you can still step into and through the sub-procedure, using F8 until it errors out again. If the sub-procedure's too long to make even that tedious, then your sub-procedure should probably have its own error handling routine.

There are multiple ways to do this. Sometimes for smaller programs where I know I'm gonna be stepping through it anyway when troubleshooting, I just put these lines right after the MsgBox statement:

    Resume ExitHere         ' Normally exits during production
    Resume                  ' Never will get here
Exit Sub

It will never get to the Resume statement, unless you're stepping through and set it as the next line to be executed, either by dragging the next statement pointer to that line, or by pressing CtrlF9 with the cursor on that line.

Here's an article that expands on these concepts: Five tips for handling errors in VBA. Finally, if you're using VBA and haven't discovered Chip Pearson's awesome site yet, he has a page explaining Error Handling In VBA.

For Angular Version 11+

Configuration

The styles and scripts options in your angular.json configuration now allow to reference a package directly:

before: "styles": ["../node_modules/bootstrap/dist/css/bootstrap.css"]
after: "styles": ["bootstrap/dist/css/bootstrap.css"]

          "builder": "@angular-devkit/build-angular:browser",
          "options": {
            "outputPath": "dist/ng6",
            "index": "src/index.html",
            "main": "src/main.ts",
            "polyfills": "src/polyfills.ts",
            "tsConfig": "src/tsconfig.app.json",
            "assets": [
              "src/favicon.ico",
              "src/assets"
            ],
            "styles": [
              "src/styles.css","bootstrap/dist/css/bootstrap.min.css"

            ],
            "scripts": [
                       "jquery/dist/jquery.min.js",
                       "bootstrap/dist/js/bootstrap.min.js"
                       ]
          },

Angular Version 10 and below

Angular v6 Onwards

CLI projects in angular 6 onwards will be using angular.json instead of .angular-cli.json for build and project configuration.

Each CLI workspace has projects, each project has targets, and each target can have configurations.Docs

. {
  "projects": {
    "my-project-name": {
      "projectType": "application",
      "architect": {
        "build": {
          "configurations": {
            "production": {},
            "demo": {},
            "staging": {},
          }
        },
        "serve": {},
        "extract-i18n": {},
        "test": {},
      }
    },
    "my-project-name-e2e": {}
  },
}

OPTION-1
execute npm install bootstrap@4 jquery --save
The JavaScript parts of Bootstrap are dependent on jQuery. So you need the jQuery JavaScript library file too.

In your angular.json add the file paths to the styles and scripts array in under build target
NOTE: Before v6 the Angular CLI project configuration was stored in <PATH_TO_PROJECT>/.angular-cli.json. As of v6 the location of the file changed to angular.json. Since there is no longer a leading dot, the file is no longer hidden by default and is on the same level.
which also means that file paths in angular.json should not contain leading dots and slash

i.e you can provide an absolute path instead of a relative path

In .angular-cli.json file Path was "../node_modules/"
In angular.json it is "node_modules/"

 "build": {
          "builder": "@angular-devkit/build-angular:browser",
          "options": {
            "outputPath": "dist/ng6",
            "index": "src/index.html",
            "main": "src/main.ts",
            "polyfills": "src/polyfills.ts",
            "tsConfig": "src/tsconfig.app.json",
            "assets": [
              "src/favicon.ico",
              "src/assets"
            ],
            "styles": [
              "src/styles.css","node_modules/bootstrap/dist/css/bootstrap.min.css"
               
            ],
            "scripts": ["node_modules/jquery/dist/jquery.min.js",
                       "node_modules/bootstrap/dist/js/bootstrap.min.js"]
          },

OPTION 2
Add files from CDN (Content Delivery Network) to your project CDN LINK

Open file src/index.html and insert

the <link> element at the end of the head section to include the Bootstrap CSS file
a <script> element to include jQuery at the bottom of the body section
a <script> element to include Popper.js at the bottom of the body section
a <script> element to include the Bootstrap JavaScript file at the bottom of the body section

  <!doctype html>
    <html>
    <head>
      <meta charset="utf-8">

    </body>
    </html>

OPTION 3
Execute npm install bootstrap
In src/styles.css add the following line:

@import "~bootstrap/dist/css/bootstrap.css";

OPTION-4
ng-bootstrap It contains a set of native Angular directives based on Bootstrap’s markup and CSS. As a result, it's not dependent on jQuery or Bootstrap’s JavaScript

npm install --save @ng-bootstrap/ng-bootstrap

After Installation import it in your root module and register it in @NgModule imports` array

import {NgbModule} from '@ng-bootstrap/ng-bootstrap';
@NgModule({
  declarations: [AppComponent, ...],
  imports: [NgbModule.forRoot(), ...],
  bootstrap: [AppComponent]
})

NOTE
ng-bootstrap requires Bootstrap's 4 css to be added in your project. you need to Install it explicitly via:
npm install bootstrap@4 --save In your angular.json add the file paths to the styles array in under build target

   "styles": [
      "src/styles.css",
      "node_modules/bootstrap/dist/css/bootstrap.min.css"
   ],

P.S Do Restart Your server

in template

<md-button class="md-fab md-mini md-warn md-ink-ripple" ng-click="export()" aria-label="Export">
<md-icon class="material-icons" alt="Export" title="Export" aria-label="Export">
    system_update_alt
</md-icon></md-button>

in controller

     $scope.export = function(){ $window.location.href = $scope.export; };

It happened to me as well. On a newly provisioned Red Hat Linux 7 server.

When I run a PHP page, i.e. info.php, I could see plain text PHP scripts instead of executing them.

I just installed PHP:

[root@localhost ~]# yum install php

And then restarted Apache HTTP Server:

[root@localhost ~]# systemctl restart httpd

I think that it's related with a route

Route::get('/article/{slug}', 'Front@slug');

associated with a particular method in my controller:

No, thats not it. The error message is coming from the route:cache command, not sure why clearing the cache calls this automatically.

The problem is a route which uses a Closure instead of a controller, which looks something like this:

//                       Thats the Closure
//                             v 
Route::get('/some/route', function() {
    return 'Hello World';
});

Since Closures can not be serialized, you can not cache your routes when you have routes which use closures.

The problem

The problem is in the network layer. Here are the status codes explained:

• Connection refused: The peer is not listening on the respective network port you're trying to connect to. This usually means that either a firewall is actively denying the connection or the respective service is not started on the other site or is overloaded.

• Connection timed out: During the attempt to establish the TCP connection, no response came from the other side within a given time limit. In the context of urllib this may also mean that the HTTP response did not arrive in time. This is sometimes also caused by firewalls, sometimes by network congestion or heavy load on the remote (or even local) site.

In context

That said, it is probably not a problem in your script, but on the remote site. If it's occuring occasionally, it indicates that the other site has load problems or the network path to the other site is unreliable.

Also, as it is a problem with the network, you cannot tell what happened on the other side. It is possible that the packets travel fine in the one direction but get dropped (or misrouted) in the other.

It is also not a (direct) DNS problem, that would cause another error (Name or service not known or something similar). It could however be the case that the DNS is configured to return different IP addresses on each request, which would connect you (DNS caching left aside) to different addresses hosts on each connection attempt. It could in turn be the case that some of these hosts are misconfigured or overloaded and thus cause the aforementioned problems.

Debugging this

As suggested in the another answer, using a packet analyzer can help to debug the issue. You won't see much however except the packets reflecting exactly what the error message says.

To rule out network congestion as a problem you could use a tool like mtr or traceroute or even ping to see if packets get lost to the remote site. Note that, if you see loss in mtr (and any traceroute tool for that matter), you must always consider the first host where loss occurs (in the route from yours to remote) as the one dropping packets, due to the way ICMP works. If the packets get lost only at the last hop over a long time (say, 100 packets), that host definetly has an issue. If you see that this behaviour is persistent (over several days), you might want to contact the administrator.

Loss in a middle of the route usually corresponds to network congestion (possibly due to maintenance), and there's nothing you could do about it (except whining at the ISP about missing redundance).

If network congestion is not a problem (i.e. not more than, say, 5% of the packets get lost), you should contact the remote server administrator to figure out what's wrong. He may be able to see relevant infos in system logs. Running a packet analyzer on the remote site might also be more revealing than on the local site. Checking whether the port is open using netstat -tlp is definetly recommended then.

Problem Solved,

I edited the file /etc/postfix/master.cf

and commented

-o smtpd_relay_restrictions=permit_sasl_authenticated,reject

and changed the line from

-o smtpd_tls_security_level=encrypt 

to

-o smtpd_tls_security_level=may

And worked on fine

The easiest way to compute the correct mouse click or mouse move position on a canvas event is to use this little equation:

canvas.addEventListener('click', event =>

    let bound = canvas.getBoundingClientRect();

    let x = event.clientX - bound.left - canvas.clientLeft;
    let y = event.clientY - bound.top - canvas.clientTop;

    context.fillRect(x, y, 16, 16);
});

If the canvas has padding-left or padding-top, subtract x and y via:

x -= parseFloat(style['padding-left'].replace('px'));
y -= parseFloat(style['padding-top'].replace('px'));

int titleId = getResources().getIdentifier("action_bar_title", "id",
            "android");
    TextView yourTextView = (TextView) findViewById(titleId);
    yourTextView.setTextColor(getResources().getColor(R.color.black));
    yourTextView.setTypeface(face);

As to the question "Can the ps3 and xbxo 360 pull off double precision floating point operations or only single precision and in generel use is the double precision capabilities made use of (if they exist?)."

I believe that both platforms are incapable of double floating point. The original Cell processor only had 32 bit floats, same with the ATI hardware which the XBox 360 is based on (R600). The Cell got double floating point support later on, but I'm pretty sure the PS3 doesn't use that chippery.

Here's a one-liner using LINQ and avoiding any run-time evaluation of select strings:

someDataTable.Rows.Cast<DataRow>().Where(
    r => r.ItemArray[0] == someValue).ToList().ForEach(r => r.Delete());

This always works fine for me:

for url in list_of_urls:
    urls.setdefault(url, 0)
    urls[url] += 1

I tried all the non-plugin approaches here, but all caused blank pages to print after the content, or had other problems. Here's my solution:

Html:

<body>
<div id="page-content">        
    <div id="printme">Content To Print</div>
    <div>Don't print this.</div>
</div>
<div id="hidden-print-div"></div>
</body>

Jquery:

    $(document).ready(function () {
        $("#hidden-print-div").html($("#printme").html());
    });

Css:

    #hidden-print-div {
        display: none;
    }

    @media print {
        #hidden-print-div {
            display: block;
        }

        #page-content {
            display: none;
        }
    }

html, body {
    min-height: 100%;
}

Will do the trick.

By default, even html and body are only as big as the content they hold, but never more than the width/height of the windows. This can often lead to quite strange results.

If you want to delete a user with sql, you need to delete the related data in these tables: columns_priv, db, procs_priv, tables_priv. Then execute flush privileges;

If by "array" you actually mean a Python list, you can use

a = [0] * 10

or

a = [None] * 10

you can try this....

    AlertDialog.Builder dialog = new AlertDialog.Builder(MainActivity.this);
dialog.setCancelable(false);
dialog.setTitle("Dialog on Android");
dialog.setMessage("Are you sure you want to delete this entry?" );
dialog.setPositiveButton("Delete", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int id) {
        //Action for "Delete".
    }
})
        .setNegativeButton("Cancel ", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
            //Action for "Cancel".
            }
        });

final AlertDialog alert = dialog.create();
alert.show();

Background

Invariant's answer is a good resource for how everything was started and what was the state of JavaFX on embedded and mobile in beginning of 2014. But, a lot has changed since then and the users who stumble on this thread do not get the updated information.

Most of my points are related to Invariant's answer, so I would suggest to go through it first.

Current Status of JavaFX on Mobile / Embedded

UPDATE

JavaFXPorts has been deprecated. Gluon Mobile now uses GraalVM underneath. There are multiple advantages of using GraalVM. Please check this blogpost from Gluon. The IDE plugins have been updated to use Gluon Client plugins which leverages GraalVM to AOT compile applications for Android/iOS.

Old answer with JavaFXPorts

Some bad news first:

• RoboVM is dead
• Oracle killed JavaFX on Embedded Devices

Now, some good news:

• JavaFX still runs on Android, iOS and most of the Embedded devices
• JavaFXPorts SDK for android, iOS and embedded devices can be downloaded from here
• JavaFXPorts project is still thriving and it is easier than ever to run JavaFX on mobile devices, all thanks to the IDE plugins that is built on top of these SDKs and gets you started in a few minutes without the hassle of installing any SDK
• JavaFX 3D is now supported on mobile devices
• GluonVM to replace RoboVM enabling Java 9 support for mobile developers. Yes, you heard it right.
• Mobile Project has been launched by Oracle to support JDK on all major mobile platforms. It should support JavaFX as well ;)

How to get started

If you are not the DIY kind, I would suggest to install the IDE plugin on your favourite IDE and get started.

Most of the documentation on how to get started can be found here and some of the samples can be found here.

As the question title asks for a regex that finds many dates, I would like to propose a new solution, although there are many solutions already.

In order to find all dates of a string that are in this millennium (2000 - 2999), for me it worked the following:

dates = re.findall('([1-9]|1[0-9]|2[0-9]|3[0-1]|0[0-9])(.|-|\/)([1-9]|1[0-2]|0[0-9])(.|-|\/)(20[0-9][0-9])',dates_ele)

dates = [''.join(dates[i]) for i in range(len(dates))]

This regex is able to find multiple dates in the same string, like bla Bla 8.05/2020 \n BLAH bla15/05-2020 blaa. As one could observe, instead of / the date can have . or -, not necessary at the same time.

Some explaining

More specifically it can find dates of format day , moth year. Day is an one digit integer or a zero followed by one digit integer or 1 or 2 followed by an one digit integer or a 3 followed by 0 or 1. Month is an one digit integer or a zero followed by one digit integer or 1 followed by 0, 1, or 2. Year is the number 20 followed by any number between 00 and 99.

Useful notes

One can add more date splitting symbols by adding | symbol at the end of both (.|-|\/). For example for adding -- one would do (.|-|\/|--)

To have years outside of this millennium one has to modify (20[0-9][0-9]) to ([0-9][0-9][0-9][0-9])

SQLite does not have a storage class set aside for storing dates and/or times. Instead, the built-in Date And Time Functions of SQLite are capable of storing dates and times as TEXT, REAL, or INTEGER values:

TEXT as ISO8601 strings ("YYYY-MM-DD HH:MM:SS.SSS"). REAL as Julian day numbers, the number of days since noon in Greenwich on November 24, 4714 B.C. according to the proleptic Gregorian calendar. INTEGER as Unix Time, the number of seconds since 1970-01-01 00:00:00 UTC. Applications can chose to store dates and times in any of these formats and freely convert between formats using the built-in date and time functions.

Having said that, I would use INTEGER and store seconds since Unix epoch (1970-01-01 00:00:00 UTC).

Just found this whilst looking for a solution. I've only tested it FF 32.0.3

box-shadow: 0 0 10px 100px #fff inset;

This is a quick example

plot(rnorm(30), xlab = expression(paste("4"^"th")))

To download a file from a Github repo, use the 'curl' command with the link to the raw file.

curl https://raw.githubusercontent.com/user/repo/filename --output filename

Add the --output option followed by the new filename to download the raw file to the newly created file.

You can also login to the redis-cli and use the MONITOR command to see what queries are happening against Redis.

If it is inline, the browser should attempt to render it within the browser window. If it cannot, it will resort to an external program, prompting the user.

With attachment, it will immediately go to the user, and not try to load it in the browser, whether it can or not.

A simple way to do what OP desires in core JS.

document.getElementById(parent.id).children[child.id];

2020 UPDATE:

Converting HTML to PDF is very simple to do now. All you have to do is use NuGet to install itext7 and itext7.pdfhtml. You can do this in Visual Studio by going to "Project" > "Manage NuGet Packages..."

Make sure to include this dependency:

using iText.Html2pdf;

Now literally just paste this one liner and you're done:

HtmlConverter.ConvertToPdf(new FileInfo(@"temp.html"), new FileInfo(@"report.pdf"));

If you're running this example in visual studio, your html file should be in the /bin/Debug directory.

If you're interested, here's a good resource. Also, note that itext7 is licensed under AGPL.

VSCommands didn't work for me and caused a problem when I installed Visual Studio 2010 aside of Visual Studio 2012.

After some experimentations I found the trick:

Go to HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers and add an entry with the name "C:\Program Files (x86)\Common Files\Microsoft Shared\MSEnv\VSLauncher.exe" and the value "RUNASADMIN".

This should solve your issue. I've also blogged about that.

If you want to do it without any extra includes:

vector<IComponent*> myComponents; //assume it has items in it already.
void RemoveComponent(IComponent* componentToRemove)
{
    IComponent* juggler;

    if (componentToRemove != NULL)
    {
        for (int currComponentIndex = 0; currComponentIndex < myComponents.size(); currComponentIndex++)
        {
            if (componentToRemove == myComponents[currComponentIndex])
            {
                //Since we don't care about order, swap with the last element, then delete it.
                juggler = myComponents[currComponentIndex];
                myComponents[currComponentIndex] = myComponents[myComponents.size() - 1];
                myComponents[myComponents.size() - 1] = juggler;

                //Remove it from memory and let the vector know too.
                myComponents.pop_back();
                delete juggler;
            }
        }
    }
}

Extended - to provide more details based on some comments

The error

Error TS2306: File 'test.ts' is not a module.

Comes from the fact described here http://exploringjs.com/es6/ch_modules.html

17. Modules

This chapter explains how the built-in modules work in ECMAScript 6.

17.1 Overview

In ECMAScript 6, modules are stored in files. There is exactly one module per file and one file per module. You have two ways of exporting things from a module. These two ways can be mixed, but it is usually better to use them separately.

17.1.1 Multiple named exports

There can be multiple named exports:

//------ lib.js ------
export const sqrt = Math.sqrt;
export function square(x) {
    return x * x;
}
export function diag(x, y) {
    return sqrt(square(x) + square(y));
}
...

17.1.2 Single default export

There can be a single default export. For example, a function:

//------ myFunc.js ------
export default function () { ··· } // no semicolon!

Based on the above we need the export, as a part of the test.js file. Let's adjust the content of it like this:

// test.js - exporting es6
export module App {
  export class SomeClass {
    getName(): string {
      return 'name';
    }
  }
  export class OtherClass {
    getName(): string {
      return 'name';
    }
  }
}

And now we can import it with these thre ways:

import * as app1 from "./test";
import app2 = require("./test");
import {App} from "./test";

And we can consume imported stuff like this:

var a1: app1.App.SomeClass  = new app1.App.SomeClass();
var a2: app1.App.OtherClass = new app1.App.OtherClass();

var b1: app2.App.SomeClass  = new app2.App.SomeClass();
var b2: app2.App.OtherClass = new app2.App.OtherClass();

var c1: App.SomeClass  = new App.SomeClass();
var c2: App.OtherClass = new App.OtherClass();

and call the method to see it in action:

console.log(a1.getName())
console.log(a2.getName())
console.log(b1.getName())
console.log(b2.getName())
console.log(c1.getName())
console.log(c2.getName())

Original part is trying to help to reduce the amount of complexity in usage of the namespace

Original part:

I would really strongly suggest to check this Q & A:

How do I use namespaces with TypeScript external modules?

Let me cite the first sentence:

Do not use "namespaces" in external modules.

Don't do this.

Seriously. Stop.

...

In this case, we just do not need module inside of test.ts. This could be the content of it adjusted test.ts:

export class SomeClass
{
    getName(): string
    {
        return 'name';
    }
}

Read more here

Export =

In the previous example, when we consumed each validator, each module only exported one value. In cases like this, it's cumbersome to work with these symbols through their qualified name when a single identifier would do just as well.

The export = syntax specifies a single object that is exported from the module. This can be a class, interface, module, function, or enum. When imported, the exported symbol is consumed directly and is not qualified by any name.

we can later consume it like this:

import App = require('./test');

var sc: App.SomeClass = new App.SomeClass();

sc.getName();

Optional Module Loading and Other Advanced Loading Scenarios

In some cases, you may want to only load a module under some conditions. In TypeScript, we can use the pattern shown below to implement this and other advanced loading scenarios to directly invoke the module loaders without losing type safety.

The compiler detects whether each module is used in the emitted JavaScript. For modules that are only used as part of the type system, no require calls are emitted. This culling of unused references is a good performance optimization, and also allows for optional loading of those modules.

The core idea of the pattern is that the import id = require('...') statement gives us access to the types exposed by the external module. The module loader is invoked (through require) dynamically, as shown in the if blocks below. This leverages the reference-culling optimization so that the module is only loaded when needed. For this pattern to work, it's important that the symbol defined via import is only used in type positions (i.e. never in a position that would be emitted into the JavaScript).

On Cygwin -mcmodel=medium is already default and doesn't help. To me adding -Wl,--image-base -Wl,0x10000000 to GCC linker did fixed the error.

Assuming the connection is established and is available in global scope;

//Check if a value exists in a table
function record_exists ($table, $column, $value) {
    global $connection;
    $query = "SELECT * FROM {$table} WHERE {$column} = {$value}";
    $result = mysql_query ( $query, $connection );
    if ( mysql_num_rows ( $result ) ) {
        return TRUE;
    } else {
        return FALSE;
    }
}

Usage: Assuming that the value to be checked is stored in the variable $username;

if (record_exists ( 'employee', 'username', $username )){
    echo "Username is not available. Try something else.";
} else {
    echo "Username is available";
}

Call a custom function?

http://msdn.microsoft.com/en-us/library/ms155798.aspx

You could always put a case statement in there to handle different types of 'blank' data.

Assuming that your button is in a form, you are not preventing the default behaviour of the button click from happening i.e. Your AJAX call is made in addition to the form submission; what you're very likely seeing is one of

1. the form submission happens faster than the AJAX call returns
2. the form submission causes the browser to abort the AJAX request and continues with submitting the form.

So you should prevent the default behaviour of the button click

$('#btnSave').click(function (e) {

    // prevent the default event behaviour    
    e.preventDefault();

    $.ajax({
        url: "/Home/SaveDetailedInfo",
        type: "POST",
        data: JSON.stringify({ 'Options': someData}),
        dataType: "json",
        traditional: true,
        contentType: "application/json; charset=utf-8",
        success: function (data) {

            // perform your save call here

            if (data.status == "Success") {
                alert("Done");
            } else {
                alert("Error occurs on the Database level!");
            }
        },
        error: function () {
            alert("An error has occured!!!");
        }
    });
});

I'm a huge fan of Castle. I love the facilities it also provides beyond the IoC Container story. It really simplfies using NHibernate, logging, AOP, etc. I also use Binsor for configuration with Boo and have really fallen in love with Boo as a language because of it.
