This is the best method to download and view PDF file.You can just call it from anywhere as like

PDFTools.showPDFUrl(context, url);

here below put the code. It will works fine

try it. it will works, enjoy

You would typically first read from the input stream and then close it. You can wrap the FileInputStream in another InputStream (or Reader). It will be automatically closed when you close the wrapping stream/reader.

If this is a method returning an InputStream to the caller, then it is the caller's responsibility to close the stream when finished with it. If you close it in your method, the caller will not be able to use it.

To answer some of your comments...

To send the contents InputStream to a remote consumer, you would write the content of the InputStream to an OutputStream, and then close both streams.

The remote consumer does not know anything about the stream objects you have created. He just receives the content, in an InputStream which he will create, read from and close.

public static void main(String[] args) {
        try {
            File file = new File("test.txt");
            System.out.println(file.length());
        } catch (Exception e) {
        }
    }

classname.getResourceAsStream() loads a file via the classloader of classname. If the class came from a jar file, that is where the resource will be loaded from.

FileInputStream is used to read a file from the filesystem.

Another alternative is to check the fractional part:

x%%1==0

or, if you want to check within a certain tolerance:

min(abs(c(x%%1, x%%1-1))) < tol

it depends on your php settings...
use phpinfo() and take a look at the session chapter. There are values like session.gc_maxlifetime and session.cache_expire and session.cookie_lifetime which affects the sessions lifetime

EDIT: it's like Martin write before

PK - Primary Key

NN - Not Null

BIN - Binary (stores data as binary strings. There is no character set so sorting and comparison is based on the numeric values of the bytes in the values.)

UN - Unsigned (non-negative numbers only. so if the range is -500 to 500, instead its 0 - 1000, the range is the same but it starts at 0)

UQ - Create/remove Unique Key

ZF - Zero-Filled (if the length is 5 like INT(5) then every field is filled with 0’s to the 5th digit. 12 = 00012, 400 = 00400, etc. )

AI - Auto Increment

G - Generated column. i.e. value generated by a formula based on the other columns

And, of course

 ("ABCD"[2] == 2["ABCD"]) && (2["ABCD"] == 'C') && ("ABCD"[2] == 'C')

The main reason for this was that back in the 70's when C was designed, computers didn't have much memory (64KB was a lot), so the C compiler didn't do much syntax checking. Hence "X[Y]" was rather blindly translated into "*(X+Y)"

This also explains the "+=" and "++" syntaxes. Everything in the form "A = B + C" had the same compiled form. But, if B was the same object as A, then an assembly level optimization was available. But the compiler wasn't bright enough to recognize it, so the developer had to (A += C). Similarly, if C was 1, a different assembly level optimization was available, and again the developer had to make it explicit, because the compiler didn't recognize it. (More recently compilers do, so those syntaxes are largely unnecessary these days)

This worked for me with a string-array named shoes loaded from the projects resources:

Spinner              spinnerCountShoes = (Spinner)findViewById(R.id.spinner_countshoes);
ArrayAdapter<String> spinnerCountShoesArrayAdapter = new ArrayAdapter<String>(
                     this,
                     android.R.layout.simple_spinner_dropdown_item, 
                     getResources().getStringArray(R.array.shoes));
spinnerCountShoes.setAdapter(spinnerCountShoesArrayAdapter);

This is my resource file (res/values/arrays.xml) with the string-array named shoes:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string-array name="shoes">
        <item>0</item>
        <item>5</item>
        <item>10</item>
        <item>100</item>
        <item>1000</item>
        <item>10000</item>
    </string-array>
</resources>

With this method it's easier to make it multilingual (if necessary).

Place the following in your jQuery mouseover event handler:

$(this).css('color', 'red');

To set both color and size at the same time:

$(this).css({ 'color': 'red', 'font-size': '150%' });

You can set any CSS attribute using the .css() jQuery function.

Here is a solution for React (not React Native) using TypeScript.

The same concept can be applied to React Native

import React from 'react';

type Props = {
  children: string;
  Wrapper?: any;
}

/**
 * Automatically break lines for text
 *
 * Avoids relying on <br /> for every line break
 *
 * @example
 * <Text>
 *   {`
 *     First line
 *
 *     Another line, which will respect line break
 *  `}
 * </Text>
 * @param props
 */
export const Text: React.FunctionComponent<Props> = (props) => {
  const { children, Wrapper = 'div' } = props;

  return (
    <Wrapper style={{ whiteSpace: 'pre-line' }}>
      {children}
    </Wrapper>
  );
};

export default Text;

Usage:

<Text>
  {`
    This page uses server side rendering (SSR)

    Each page refresh (either SSR or CSR) queries the GraphQL API and displays products below:
  `}
</Text>

Displays:

I've similar issues on a Mac. What I did;

• 1) on the emulator, settings-display -> disable screen orientation
• 2) on Eclipse, emulator startup options -> -cpu-delay 100

Those had some effect in lowering CPU use (not it is around 40-60%), not ultimate solution. But again, the CPU use is NOT >100% anymore!

add the following to you preamble:

\newcommand{\newCommandName}{text to insert}

Then you can just use \newCommandName{} in the text

For more info on \newcommand, see e.g. wikibooks

Example:

\documentclass{article}
\newcommand\x{30}
\begin{document}
\x
\end{document}

Output:

30

The setInterval() method, repeatedly calls a function or executes a code snippet, with a fixed time delay between each call. It returns an interval ID which uniquely identifies the interval, so you can remove it later by calling clearInterval().

var intervalId = setInterval(function() {
  alert("Interval reached every 5s")
}, 5000);

// You can clear a periodic function by uncommenting:
// clearInterval(intervalId);

See more @ setInterval() @ MDN Web Docs

Strings are just as iterable as arrays, so just convert it to string:

str(12345)

Since you are not interested in keeping any data, drop the entire database and create a new one.

If you already know for sure that the user is logged in (in your example if /index.html is protected):

UserDetails userDetails =
 (UserDetails)SecurityContextHolder.getContext().getAuthentication().getPrincipal();

To first check if the user is logged in, check that the current Authentication is not a AnonymousAuthenticationToken.

Authentication auth = SecurityContextHolder.getContext().getAuthentication();
if (!(auth instanceof AnonymousAuthenticationToken)) {
        // userDetails = auth.getPrincipal()
}

There is also the _reindex option

From documentation:

Through the Elasticsearch reindex API, available in version 5.x and later, you can connect your new Elasticsearch Service deployment remotely to your old Elasticsearch cluster. This pulls the data from your old cluster and indexes it into your new one. Reindexing essentially rebuilds the index from scratch and it can be more resource intensive to run.

POST _reindex
{
  "source": {
    "remote": {
      "host": "https://REMOTE_ELASTICSEARCH_ENDPOINT:PORT",
      "username": "USER",
      "password": "PASSWORD"
    },
    "index": "INDEX_NAME",
    "query": {
      "match_all": {}
    }
  },
  "dest": {
    "index": "INDEX_NAME"
  }
}

Meder Omuraliev suggested to use an event handler and set scrollTo(0,0). This is an example for Wassim-azirar. Bringing it all together, I assume this is the final solution.

We have 3 problems: the scrollbar, scrolling with mouse, and keyboard. This hides the scrollbar:

       html, body{overflow:hidden;}

Unfortunally, you can still scroll with the keyboard: To prevent this, we can:

    function keydownHandler(e) {
var evt = e ? e:event;
  var keyCode = evt.keyCode;

  if (keyCode==38 || keyCode==39 || keyCode==40 || keyCode==37){ //arrow keys
e.preventDefault()
scrollTo(0,0);
}
}

document.onkeydown=keydownHandler;

The scrolling with the mouse just naturally doesn't work after this code, so we have prevented the scrolling.

For example: https://jsfiddle.net/aL7pes70/1/

For anyone else who stumbles across this thread but needs to find or create an object with attributes that might change depending on the circumstances, add the following method to your model:

# Return the first object which matches the attributes hash
# - or -
# Create new object with the given attributes
#
def self.find_or_create(attributes)
  Model.where(attributes).first || Model.create(attributes)
end

Optimization tip: regardless of which solution you choose, consider adding indexes for the attributes you are querying most frequently.

Here is my function:

using System;
using System.Collections.Generic;
class HexadecimalToDecimal
{
    static Dictionary<char, int> hexdecval = new Dictionary<char, int>{
        {'0', 0},
        {'1', 1},
        {'2', 2},
        {'3', 3},
        {'4', 4},
        {'5', 5},
        {'6', 6},
        {'7', 7},
        {'8', 8},
        {'9', 9},
        {'a', 10},
        {'b', 11},
        {'c', 12},
        {'d', 13},
        {'e', 14},
        {'f', 15},
    };

    static decimal HexToDec(string hex)
    {
        decimal result = 0;
        hex = hex.ToLower();

        for (int i = 0; i < hex.Length; i++)
        {
            char valAt = hex[hex.Length - 1 - i];
            result += hexdecval[valAt] * (int)Math.Pow(16, i);
        }

        return result;
    }

    static void Main()
    {

        Console.WriteLine("Enter Hexadecimal value");
        string hex = Console.ReadLine().Trim();

        //string hex = "29A";
        Console.WriteLine("Hex {0} is dec {1}", hex, HexToDec(hex));

        Console.ReadKey();
    }
}

Here seems to be an even better answer with 'in' clause that allows for multiple keys for the join:

update fp_active set STATE='E', 
   LAST_DATE_MAJ = sysdate where (client,code) in (select (client,code) from fp_detail
  where valid = 1) ...

The full example is here: http://forums.devshed.com/oracle-development-96/how-to-update-from-two-tables-195893.html - from web archive since link was dead.

The beef is in having the columns that you want to use as the key in parentheses in the where clause before 'in' and have the select statement with the same column names in parentheses. where (column1,column2) in ( select (column1,column2) from table where "the set I want" );

Not sure if you are coding these programs, but this is a simple example of how you'd do it.

program1.c

#include <stdio.h>
int main (int argc, char * argv[] ) {
    printf("%s", argv[1]); 
    return 0;
}

rgx.cpp

#include <cstdio>
#include <regex>
#include <iostream>
using namespace std;
int main (int argc, char * argv[] ) {
    char input[200];
    fgets(input,200,stdin);
    string s(input)
    smatch m;
    string reg_exp(argv[1]);
    regex e(reg_exp);
    while (regex_search (s,m,e)) {
      for (auto x:m) cout << x << " ";
      cout << endl;
      s = m.suffix().str();
    }
    return 0;
}

Compile both then run program1.exe "this subject has a submarine as a subsequence" | rgx.exe "\b(sub)([^ ]*)"

The | operator simply redirects the output of program1's printf operation from the stdout stream to the stdin stream whereby it's sitting there waiting for rgx.exe to pick up.

It seems to me there is value in considering some rewrites to your SQL code before attempting to translate it.

Personally, I'd write such a query as a union (although I'd avoid nulls entirely!):

SELECT f.value
  FROM period as p JOIN facts AS f ON p.id = f.periodid
WHERE p.companyid = 100
      AND f.otherid = 17
UNION
SELECT NULL AS value
  FROM period as p
WHERE p.companyid = 100
      AND NOT EXISTS ( 
                      SELECT * 
                        FROM facts AS f
                       WHERE p.id = f.periodid
                             AND f.otherid = 17
                     );

So I guess I agree with the spirit of @MAbraham1's answer (though their code seems to be unrelated to the question).

However, it seems the query is expressly designed to produce a single column result comprising duplicate rows -- indeed duplicate nulls! It's hard not to come to the conclusion that this approach is flawed.

By default time zone of laravel project is **UTC*

• you can find time zone setting in App.php of config folder

'timezone' => 'UTC',

now change according to your time zone for me it's Asia/Calcutta

so for me setting will be 'timezone' => 'Asia/Calcutta',

• After changing your time zone setting run command php artisan config:cache

*for time zone list visit this url https://www.w3schools.com/php/php_ref_timezones.asp

Using dt.weekday_name is deprecated since pandas 0.23.0, instead, use dt.day_name():

df = pd.DataFrame({'my_dates':['2015-01-01','2015-01-02','2015-01-03'],'myvals':[1,2,3]})
df['my_dates'] = pd.to_datetime(df['my_dates'])

df['my_dates'].dt.day_name()

0    Thursday
1      Friday
2    Saturday
Name: my_dates, dtype: object

Adding to the above mentioned benefits of swap(). That clear() does not guarantee deallocation of memory. You can use swap() as follows:

std::vector<T>().swap(myvector);

Yes, it's indeed a sad fact that keytool has no functionality to import a private key.

For the record, at the end I went with the solution described here

You can remove the time component when comparing:

SELECT * 
FROM sales 
WHERE CONVERT(DATETIME, FLOOR(CONVERT(FLOAT, salesDate))) = '11/11/2010'

Another approach is to change the select to cover all the time between the start and end of the date:

SELECT * 
FROM sales 
-- WHERE salesDate BETWEEN '11/11/2010 00:00:00.00' AND '11/11/2010 23:59:59.999'
WHERE salesDate BETWEEN '2020-05-18T00:00:00.00' AND '2020-05-18T23:59:59.999'

You can just use:

> names(LIST)
[1] "A" "B"

Obviously the names of the first element is just

> names(LIST)[1]
[1] "A"

Maybe you can pipe SQL query to sqlplus. It works for mysql:

echo "SELECT * FROM table" | mysql --user=username database

This is the best format. Works in all of those cases:

String.Format( "{0:#,##0.##}", 0 ); // 0
String.Format( "{0:#,##0.##}", 0.5 ); // 0.5 - some of the formats above fail here. 
String.Format( "{0:#,##0.##}", 12314 ); // 12,314
String.Format( "{0:#,##0.##}", 12314.23123 ); // 12,314.23
String.Format( "{0:#,##0.##}", 12314.2 ); // 12,314.2
String.Format( "{0:#,##0.##}", 1231412314.2 ); // 1,231,412,314.2

I followed these steps:

Pull the master:

git pull origin master

This will sync your local repo with the Github repo. Add your new file and then:

git add .

Commit the changes:

git commit -m "adding new file  Xyz"

Finally, push the origin master:

git push origin master

Refresh your Github repo, you will see the newly added files.

public static void main(String[] args) {
    Scanner scanner = new Scanner(System.in);
    String satr=scanner.nextLine();
    String newString = "";
    for (int i = 0; i < satr.length(); i++) {
        if (Character.isUpperCase(satr.charAt(i))) {
            newString+=Character.toLowerCase(satr.charAt(i));
        }else newString += Character.toUpperCase(satr.charAt(i));
    }
    System.out.println(newString);
}

I have similar issue on touch devices. Adding "touch-action: none" to the element resolved the issue.

For more information. Check this out:-

A cleaner way of iterating the lists is:

// initialise the collection
collection = new ArrayList<ArrayList<String>>();
// iterate
for (ArrayList<String> innerList : collection) {
    for (String string : innerList) {
        // do stuff with string
    }
}

The one mahesh posted is not working because the attribute name is missing:

So instead of

<input id="list" class="required"  />

You can use:

<input id="list" name="list" class="required"  />

WITH CHECK is indeed the default behaviour however it is good practice to include within your coding.

The alternative behaviour is of course to use WITH NOCHECK, so it is good to explicitly define your intentions. This is often used when you are playing with/modifying/switching inline partitions.

Have a look at ConcurrentSkipListMap. It should give you log(n) time for testing and removing an element if it is already contained in the cache, and constant time for re-adding it.

You'd just need some counter etc and wrapper element to force ordering of the LRU order and ensure recent stuff is discarded when the cache is full.

A lock should be considered to use, such as threading.Lock. See lock-objects for more info.

The accepted answer CAN print 10 by thread1, which is not what you want. You can run the following code to understand the bug more easily.

def thread1(threadname):
    while True:
      if a % 2 and not a % 2:
          print "unreachable."

def thread2(threadname):
    global a
    while True:
        a += 1

Using a lock can forbid changing of a while reading more than one time:

def thread1(threadname):
    while True:
      lock_a.acquire()
      if a % 2 and not a % 2:
          print "unreachable."
      lock_a.release()

def thread2(threadname):
    global a
    while True:
        lock_a.acquire()
        a += 1
        lock_a.release()

If thread using the variable for long time, coping it to a local variable first is a good choice.

I would strongly suspect this is not possible, because it would be an incredible security problem if it were. For example, I could make a page which looked like a bank login page, and make the URL in the address bar look just like the real bank!

Perhaps if you explain why you want to do this, folks might be able to suggest alternative approaches...

[Edit in 2011: Since I wrote this answer in 2008, more info has come to light regarding an HTML5 technique that allows the URL to be modified as long as it is from the same origin]

I'd recommend starting by carefully reading this post by Peter Norvig. (I had to something similar and I found it extremely useful.)

The following function, in particular has the ideas that you now need to make your spell checker more sophisticated: splitting, deleting, transposing, and inserting the irregular words to 'correct' them.

def edits1(word):
   splits     = [(word[:i], word[i:]) for i in range(len(word) + 1)]
   deletes    = [a + b[1:] for a, b in splits if b]
   transposes = [a + b[1] + b[0] + b[2:] for a, b in splits if len(b)>1]
   replaces   = [a + c + b[1:] for a, b in splits for c in alphabet if b]
   inserts    = [a + c + b     for a, b in splits for c in alphabet]
   return set(deletes + transposes + replaces + inserts)

Note: The above is one snippet from Norvig's spelling corrector

And the good news is that you can incrementally add to and keep improving your spell-checker.

Hope that helps.

An array is created with the -split operator. Like so,

$myString="Four score and seven years ago"
$arr = $myString -split ' '
$arr # Print output
Four
score
and
seven
years
ago

When you need a certain item, use array index to reach it. Mind that index starts from zero. Like so,

$arr[2] # 3rd element
and
$arr[4] # 5th element
years

This is because ASP.NET it changing the Id of your textbox, if you run your page, and do a view source, you will see the text box id is something like

ctl00_ContentColumn_txt_model_code

There are a few ways round this:

Use the actual control name:

var TestVar = document.getElementById('ctl00_ContentColumn_txt_model_code').value;

use the ClientID property within ASP script tags

document.getElementById('<%= txt_model_code.ClientID %>').value;

Or if you are running .NET 4 you can use the new ClientIdMode property, see this link for more details.

http://weblogs.asp.net/scottgu/archive/2010/03/30/cleaner-html-markup-with-asp-net-4-web-forms-client-ids-vs-2010-and-net-4-0-series.aspx1

In Command line mode: I have planned on Linux OS.

1. download the latest jmeter version. Apache JMeter 3.2 (Requires Java 8 or later) as of now.

2. Extract in your desired directory. For example, extract to /tmp/

3. Now, default output file format will be csv. No need to change anything or specify in the CLI command. for example: ./jmeter -n -t examples/test.jmx -l examples/output.csv

For changing the default format, change the following parameter in jmeter.properties : jmeter.save.saveservice.output_format=xml

Now if you run the command : ./jmeter -n -t examples/test.jmx -l examples/output.jtl output get stored in xml format.

Now, make the request on multiple server(Additional info query): We can specify host and port as tags in

./jmeter -n -t examples/test.jmx -l examples/output.jtl -JHOST=<HOST> -JPORT=<PORT>

There are at least two ways for achieving this in base graph (my examples are for the x-axis, but work the same for the y-axis):

1. Use par(xaxp = c(x1, x2, n)) or plot(..., xaxp = c(x1, x2, n)) to define the position (x1 & x2) of the extreme tick marks and the number of intervals between the tick marks (n). Accordingly, n+1 is the number of tick marks drawn. (This works only if you use no logarithmic scale, for the behavior with logarithmic scales see ?par.)

2. You can suppress the drawing of the axis altogether and add the tick marks later with axis().
   To suppress the drawing of the axis use plot(... , xaxt = "n").
   Then call axis() with side, at, and labels: axis(side = 1, at = v1, labels = v2). With side referring to the side of the axis (1 = x-axis, 2 = y-axis), v1 being a vector containing the position of the ticks (e.g., c(1, 3, 5) if your axis ranges from 0 to 6 and you want three marks), and v2 a vector containing the labels for the specified tick marks (must be of same length as v1, e.g., c("group a", "group b", "group c")). See ?axis and my updated answer to a post on stats.stackexchange for an example of this method.

I know this thread is a little old but we ran into this too and will archive our eventual solution here for others.

We had the same problem with a Comodo wildcard "positive ssl" cert. We are running our website using a squid-reverse SSL proxy and Firefox would keep complaining "sec_error_unknown_issuer" as you stated, yet every other browser was OK.

I found that this is a problem of the certificate chain being incomplete. Firefox apparently does not have one of the intermediary certificates build in, though Firefox does trust the root CA. Therefore you have to provide the whole chain of certificates to Firefox. Comodo's support states:

An intermediate certificate is the certificate, or certificates, that go between your site (server) certificate and a root certificate. The intermediate certificate, or certificates, completes the chain to a root certificate trusted by the browser.

Using an intermediate certificate means that you must complete an additional step in the installation process to enable your site certificate to be chained to the trusted root, and not show errors in the browser when someone visits your web site.

This was already touched on earlier in this thread but it did not resove how you do this.

First you have to make a chained certificate bundle and you do that by using your favorite text editor and just paste them in, in the correct (reverse) order i.e.

• Intermediate CA Certificate 2 - IntermediateCA2.crt - on top of the file
• Intermediate CA Certificate 1 - IntermediateCA1.crt
• Root CA Certificate - root.crt - at the end of the file

The exact order you can get from your ssl provider if its not obvious from the names.

Then save the file as whatever name you like. E.g. yourdomain-chain-bundle.crt

In this example I have not included the actual domain certificate and as long as your server can be configured to take a separate chained certificate bundle this is what you use.

More data can be found here:

https://support.comodo.com/index.php?/Knowledgebase/Article/View/643/0/how-do-i-make-my-own-bundle-file-from-crt-files

If for some reason you can't configure your server to use a separate chained bundle, then you just paste your server certificate in the beginning (on the top) of the bundle and use the resulting file as your server cert. This is what needs to be done in the E.g Squid case. See below from the squid mailing list on this subject.

http://www.squid-cache.org/mail-archive/squid-users/201109/0037.html

This resolved it for us.

It means the connection was successfully established at some point, but when you tried to commit right there, the connection was no longer open. The parameters you mentioned sound like connection pool settings. If so, they're unrelated to this problem. The most likely cause is a firewall between you and the database that is killing connections after a certain amount of idle time. The most common fix is to make your connection pool run a validation query when a connection is checked out from it. This will immediately identify and evict dead connnections, ensuring that you only get good connections out of the pool.

Well, instead of passing Application.Current.MainWindow, just pass a reference to whichever window it is you want: new WindowInteropHelper(this).Handle and so on.

Or on an actual device you can go to Settings -> Mobile Networks -> Preferred network types and chose the slowest available... Of course this is very limited, but for some test- purposes it might be enough.

Use the Count(*) analytic function OVER PARTITION BY NULL This will count the total # of rows

FYI, in this case the cause was found to be mixed case column name in the DDL for table creation.

However, if you are mixing "old style" and ANSI joins you could get the same error message even when the DDL was done properly with uppercase table name. This happened to me, and google sent me to this stackoverflow page so I thought I'd share since I was here.

--NO PROBLEM: ANSI syntax
SELECT A.EMPLID, B.FIRST_NAME, C.LAST_NAME
FROM PS_PERSON A
INNER JOIN PS_NAME_PWD_VW B ON B.EMPLID = A.EMPLID
INNER JOIN PS_HCR_PERSON_NM_I C ON C.EMPLID = A.EMPLID
WHERE 
    LENGTH(A.EMPLID) = 9
    AND LENGTH(B.LAST_NAME) > 5
    AND LENGTH(C.LAST_NAME) > 5
ORDER BY 1, 2, 3
/

--NO PROBLEM: OLD STYLE/deprecated/traditional oracle proprietary join syntax

    and C.EMPLID = A.EMPLID
    and LENGTH(A.EMPLID) = 9
    AND LENGTH(B.LAST_NAME) > 5
    AND LENGTH(C.LAST_NAME) > 5
ORDER BY 1, 2, 3
/

The two SQL statements above are equivalent and produce no error.

When you try to mix them you can get lucky, or you can get an Oracle has a ORA-00904 error.

--LUCKY: mixed syntax (ANSI joins appear before OLD STYLE)

    and LENGTH(A.EMPLID) = 9
    AND LENGTH(B.FIRST_NAME) > 5
    AND LENGTH(C.LAST_NAME) > 5

And the unhelpful error message that doesn't really describe the problem at all:

>[Error] Script lines: 1-12 -------------------------
ORA-00904: "A"."EMPLID": invalid identifier  Script line 6, statement line 6,
column 51 

I was able to find some research on this in the following blog post:

• http://sqlfascination.com/2013/08/17/oracle-ansi-vs-old-style-joins/

In my case, I was attempting to manually convert from old style to ANSI style joins, and was doing so incrementally, one table at a time. This appears to have been a bad idea. Instead, it's probably better to convert all tables at once, or comment out a table and its where conditions in the original query in order to compare with the new ANSI query you are writing.

<b> and <i> are both related to style, whereas <em> and <strong> are semantic. In HTML 4, the first are classified as font style elements, and the latter as phrase elements.

As you indicated correctly, <i> and <em> are often considered similar, because browsers often render both in italics. But according to the specifications, <em> indicates emphasis and <strong> indicates stronger emphasis, which is quite clear, but often misinterpreted. On the other hand, the distinction between when to use <i> or <b> is really a matter of style.

There's also the DateTime class which implements a function for comparison operators.

// $now = new DateTime();
$dtA = new DateTime('05/14/2010 3:00PM');
$dtB = new DateTime('05/14/2010 4:00PM');

if ( $dtA > $dtB ) {
  echo 'dtA > dtB';
}
else {
  echo 'dtA <= dtB';
}

Just catch the submit event and prevent that, then do ajax

$(document).ready(function () {
    $('#myform').on('submit', function(e) {
        e.preventDefault();
        $.ajax({
            url : $(this).attr('action') || window.location.pathname,
            type: "GET",
            data: $(this).serialize(),
            success: function (data) {
                $("#form_output").html(data);
            },
            error: function (jXHR, textStatus, errorThrown) {
                alert(errorThrown);
            }
        });
    });
});

Here are the few techniques I've heard of:

1. Use clone() if the class implements Cloneable. This API is a bit flawed in java and I never quite understood why clone is not defined in the interface, but in Object. Still, it might work.

2. Create a clone manually. If there is a constructor that accepts all parameters, it might be simple, e.g new User( user.ID, user.Age, ... ). You might even want a constructor that takes a User: new User( anotherUser ).

3. Implement something to copy from/to a user. Instead of using a constructor, the class may have a method copy( User ). You can then first snapshot the object backupUser.copy( user ) and then restore it user.copy( backupUser ). You might have a variant with methods named backup/restore/snapshot.

4. Use the state pattern.

5. Use serialization. If your object is a graph, it might be easier to serialize/deserialize it to get a clone.

That all depends on the use case. Go for the simplest.

EDIT

I also recommend to have a look at these questions:

• Clone() vs. Copy constructor
• How to properly override clone method

In ng6 you need to use this command, according to a similar post:

ng config schematics.@schematics/angular:component '{ styleext: "scss"}'

For people searching the equivalent in SwiftUI for Textfield this is accentColor:

TextField("Label", text: $self.textToBind).accentColor(Color.red)

Note that if the problem is being caused by appearing scrollbars, putting

body {
  overflow: hidden;
}

in your CSS might be an easy fix (if you don't need the page to scroll).

You can try this tool I made:

Mr. Data Converter

It converts to JSON, XML and others.

It's all client side, too, so your data never leaves your computer.

kwargs are a syntactic sugar to pass name arguments as dictionaries(for func), or dictionaries as named arguments(to func)

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.

java: Java application executor which is associated with a console to display output/errors

javaw: (Java windowed) application executor not associated with console. So no display of output/errors. It can be used to silently push the output/errors to text files. It is mostly used to launch GUI-based applications.

javaws: (Java web start) to download and run the distributed web applications. Again, no console is associated.

All are part of JRE and use the same JVM.

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());

Copy text from HTML input to the clipboard:

 function myFunction() {_x000D_
   /* Get the text field */_x000D_
   var copyText = document.getElementById("myInput");_x000D_
_x000D_
   /* Select the text field */_x000D_
   copyText.select();_x000D_
_x000D_
   /* Copy the text inside the text field */_x000D_
   document.execCommand("Copy");_x000D_
_x000D_
   /* Alert the copied text */_x000D_
   alert("Copied the text: " + copyText.value);_x000D_
 }

 <!-- The text field -->_x000D_
 <input type="text" value="Hello Friend" id="myInput">_x000D_
_x000D_
 <!-- The button used to copy the text -->_x000D_
<button onclick="myFunction()">Copy text</button>

Note: The document.execCommand() method is not supported in Internet Explorer 9 and earlier.

if you can use jQuery you can use this

<form method="get" action="something.php" id="myForm">
    <input type="text" name="name" />

    <input type="submit" style="display:none" />
</form>

<input type="button" value="Submit" id="myButton" />

<script type="text/javascript">
    $(document).ready(function() {
       $("#myButton").click(function() {
           $("#myForm").submit();
       });
    });
</script>

So, the bottom line is to create a button like Submit, and put the real submit button in the form(of course hiding it), and submit form by jquery via clicking the 'Fake Submit' button. Hope it helps.

The regex you're looking for is ^[A-Za-z.\s_-]+$

• ^ asserts that the regular expression must match at the beginning of the subject
• [] is a character class - any character that matches inside this expression is allowed
• A-Z allows a range of uppercase characters
• a-z allows a range of lowercase characters
• . matches a period rather than a range of characters
• \s matches whitespace (spaces and tabs)
• _ matches an underscore
• - matches a dash (hyphen); we have it as the last character in the character class so it doesn't get interpreted as being part of a character range. We could also escape it (\-) instead and put it anywhere in the character class, but that's less clear
• + asserts that the preceding expression (in our case, the character class) must match one or more times
• $ Finally, this asserts that we're now at the end of the subject

When you're testing regular expressions, you'll likely find a tool like regexpal helpful. This allows you to see your regular expression match (or fail to match) your sample data in real time as you write it.

In 2017, the thing closest to Javadoc would probably DocFx which was developed by Microsoft and comes as a Commmand-Line-Tool as well as a VS2017 plugin.

It's still a little rough around the edges but it looks promising.

Another alternative would be Wyam which has a documentation recipe suitable for net aplications. Look at the cake documentation for an example.

val() should handle both cases

  <option value="1">it's me</option>      


$('select').val('1'); // selects "it's me"

$('select').val("it's me"); // also selects "it's me"

i wanted to mention Jailbreak specifically (GitHub):

Jailbreak

Jailbreak is a tool for exporting certificates marked as non-exportable from the Windows certificate store. This can help when you need to extract certificates for backup or testing. You must have full access to the private key on the filesystem in order for jailbreak to work.

Prerequisites: Win32

You need to examine (put a breakpoint on / Quick Watch) the Request object in the Page_Load method of your Test.aspx.cs file.

you can use in_array function of php

$array=array('abc', 'def', 'hij', 'klm', 'nop');

if (in_array($val,$array))
{
  echo 'Value found';
}

I have a similar situation but I want a consistent way to be able to use DateTime.Parse from the filename as well, so I went with

DateTime.Now.ToString("s").Replace(":", ".") // <-- 2016-10-25T16.50.35

When I want to parse, I can simply reverse the Replace call. This way I don't have to type in any yymmdd stuff or guess what formats DateTime.Parse allows.

Create Table as select (CTAS) is possible in Hive.

You can try out below command:

CREATE TABLE new_test 
    row format delimited 
    fields terminated by '|' 
    STORED AS RCFile 
AS select * from source where col=1

1. Target cannot be partitioned table.
2. Target cannot be external table.
3. It copies the structure as well as the data

Create table like is also possible in Hive.

1. It just copies the source table definition.

SEL is a type that represents a selector in Objective-C. The @selector() keyword returns a SEL that you describe. It's not a function pointer and you can't pass it any objects or references of any kind. For each variable in the selector (method), you have to represent that in the call to @selector. For example:

-(void)methodWithNoParameters;
SEL noParameterSelector = @selector(methodWithNoParameters);

-(void)methodWithOneParameter:(id)parameter;
SEL oneParameterSelector = @selector(methodWithOneParameter:); // notice the colon here

-(void)methodWIthTwoParameters:(id)parameterOne and:(id)parameterTwo;
SEL twoParameterSelector = @selector(methodWithTwoParameters:and:); // notice the parameter names are omitted

Selectors are generally passed to delegate methods and to callbacks to specify which method should be called on a specific object during a callback. For instance, when you create a timer, the callback method is specifically defined as:

-(void)someMethod:(NSTimer*)timer;

So when you schedule the timer you would use @selector to specify which method on your object will actually be responsible for the callback:

@implementation MyObject

-(void)myTimerCallback:(NSTimer*)timer
{
    // do some computations
    if( timerShouldEnd ) {
      [timer invalidate];
    }
}

@end

// ...

int main(int argc, const char **argv)
{
    // do setup stuff
    MyObject* obj = [[MyObject alloc] init];
    SEL mySelector = @selector(myTimerCallback:);
    [NSTimer scheduledTimerWithTimeInterval:30.0 target:obj selector:mySelector userInfo:nil repeats:YES];
    // do some tear-down
    return 0;
}

In this case you are specifying that the object obj be messaged with myTimerCallback every 30 seconds.

I have problem running the py files in my java code using eclipse/STS, getting PyException due to insufficient jvm heap memory. I have done the changes as mentioned below and I'm able to resolve this issue. Below is my System configuration.

And these are the changes I did in my workspace and voila it runs perfect now.

UPDATE myTable 
   SET myColumn = NULL 
 WHERE myCondition

 $.ajax({     
     type: "POST",
     url: '/admin/systemgoalssystemgoalupdate?format=html',
     data: formdata,
     success: function (data) {
         console.log(data);
     },
     dataType: "json"
 });

You can not put

$connection = sqlite_open("[path]/data/users.sqlite", 0666);

outside the class construction. You have to put that line inside a function or the constructor but you can not place it where you have now.

The approved answer is great but that creates a new set every time.

If you want to mutate an existing object instead, use a helper function.

Set

function concatSets(set, ...iterables) {
    for (const iterable of iterables) {
        for (const item of iterable) {
            set.add(item);
        }
    }
}

Usage:

const setA = new Set([1, 2, 3]);
const setB = new Set([4, 5, 6]);
const setC = new Set([7, 8, 9]);
concatSets(setA, setB, setC);
// setA will have items 1, 2, 3, 4, 5, 6, 7, 8, 9

Map

function concatMaps(map, ...iterables) {
    for (const iterable of iterables) {
        for (const item of iterable) {
            map.set(...item);
        }
    }
}

Usage:

const mapA = new Map().set('S', 1).set('P', 2);
const mapB = new Map().set('Q', 3).set('R', 4);
concatMaps(mapA, mapB);
// mapA will have items ['S', 1], ['P', 2], ['Q', 3], ['R', 4]

SQLFiddle will let you test out your queries, while it doesn't explicitly correct syntax etc. per se it does let you play around with the script and will definitely let you know if things are working or not.

I think what you are asking is the difference between RPC Literal, Document Literal and Document Wrapped SOAP web services.

Note that Document web services are delineated into literal and wrapped as well and they are different - one of the primary difference is that the latter is BP 1.1 compliant and the former is not.

Also, in Document Literal the operation to be invoked is not specified in terms of its name whereas in Wrapped, it is. This, I think, is a significant difference in terms of easily figuring out the operation name that the request is for.

In terms of RPC literal versus Document Wrapped, the Document Wrapped request can be easily vetted / validated against the schema in the WSDL - one big advantage.

I would suggest using Document Wrapped as the web service type of choice due to its advantages.

SOAP on HTTP is the SOAP protocol bound to HTTP as the carrier. SOAP could be over SMTP or XXX as well. SOAP provides a way of interaction between entities (client and servers, for example) and both entities can marshal operation arguments / return values as per the semantics of the protocol.

If you were using XML over HTTP (and you can), it is simply understood to be XML payload on HTTP request / response. You would need to provide the framework to marshal / unmarshal, error handling and so on.

If you have multiple ul and want to empty specific ul then use id eg:

<ul id="randomName">
   <li>1</li>
   <li>2</li>
   <li>3</li>
</ul>


<script>
  $('#randomName').empty();
</script>

$('input').click(function() {_x000D_
  $('#randomName').empty()_x000D_
})

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
_x000D_
<ul id="randomName">_x000D_
  <li>1</li>_x000D_
  <li>2</li>_x000D_
  <li>3</li>_x000D_
</ul>_x000D_
_x000D_
<ul>_x000D_
  <li>4</li>_x000D_
  <li>5</li>_x000D_
</ul>_x000D_
<input type="button" value="click me" />

To clear cookie and cache from Webview,

    // Clear all the Application Cache, Web SQL Database and the HTML5 Web Storage
    WebStorage.getInstance().deleteAllData();

    // Clear all the cookies
    CookieManager.getInstance().removeAllCookies(null);
    CookieManager.getInstance().flush();

    webView.clearCache(true);
    webView.clearFormData();
    webView.clearHistory();
    webView.clearSslPreferences();

So when loading the csv data file, we'll need to set the date column as index now as below, in order to filter data based on a range of dates. This was not needed for the now deprecated method: pd.DataFrame.from_csv().

If you just want to show the data for two months from Jan to Feb, e.g. 2020-01-01 to 2020-02-29, you can do so:

import pandas as pd
mydata = pd.read_csv('mydata.csv',index_col='date') # or its index number, e.g. index_col=[0]
mydata['2020-01-01':'2020-02-29'] # will pull all the columns
#if just need one column, e.g. Cost, can be done:
mydata['2020-01-01':'2020-02-29','Cost'] 

This has been tested working for Python 3.7. Hope you will find this useful.

I have done something similar to this. One approach is to interpolate over the animation time the height of the view over time inside the rows onMeasure while issuing requestLayout() for the listView. Yes it may be be better to do inside the listView code directly but it was a quick solution (that looked good!)

Slightly off-topic, but I found this too useful not to be mentioned here.

What if we would like to read the the Html text from string.xml resource and thus make it easy to localize. CDATA make this possible:

<string name="my_text">
  <![CDATA[
    <b>Autor:</b> Mr Nice Guy<br/>
    <b>Contact:</b> [email protected]<br/>
    <i>Copyright © 2011-2012 Intergalactic Spacebar Confederation </i>
  ]]>
</string> 

From our Java code we could now utilize it like this:

TextView tv = (TextView) findViewById(R.id.myTextView);
tv.setText(Html.fromHtml(getString(R.string.my_text))); 

I did not expect this to work. But it did.

Hope it's useful to some of you!

Another option would be to use a procedure with output parameters - Using a Stored Procedure with Output Parameters

why not use "in" instead?

Select *
from table
where columnname in (word1, word2, word3)

Read your reference more carefully:

Default Values

It's not always necessary to assign a value when a field is declared. Fields that are declared but not initialized will be set to a reasonable default by the compiler. Generally speaking, this default will be zero or null, depending on the data type. Relying on such default values, however, is generally considered bad programming style.

The following chart summarizes the default values for the above data types.

. . .

Local variables are slightly different; the compiler never assigns a default value to an uninitialized local variable. If you cannot initialize your local variable where it is declared, make sure to assign it a value before you attempt to use it. Accessing an uninitialized local variable will result in a compile-time error.

To simplify, make sure to add a hash bang to the top of your ExecStart script, i.e.

#!/bin/bash

python -u alwayson.py    

Surround your %1 with something.

Eg:

if not "%1" == ""

Another one I've seen fairly often:

if not {%1} == {}

And so on...

The problem, as you can likely guess, is that the %1 is literally replaced with emptiness. It is not 'an empty string' it is actually a blank spot in your source file at that point.

Then after the replacement, the interpreter tries to parse the if statement and gets confused.

Forward declare class B and swap order of A and B definitions: 1st B and 2nd A. You can not call methods of forward declared B class.

I here have a nice and versatile solution with a fallback:

<script type="text/javascript">
    var audiotypes={
        "mp3": "audio/mpeg",
        "mp4": "audio/mp4",
        "ogg": "audio/ogg",
        "wav": "audio/wav"
    }

    function ss_soundbits(sound){
        var audio_element = document.createElement('audio')
        if (audio_element.canPlayType){
            for (var i=0; i<arguments.length; i++){
                var source_element = document.createElement('source')
                source_element.setAttribute('src', arguments[i])
                if (arguments[i].match(/\.(\w+)$/i))
                    source_element.setAttribute('type', audiotypes[RegExp.$1])
                audio_element.appendChild(source_element)
            }
            audio_element.load()
            audio_element.playclip=function(){
                audio_element.pause()
                audio_element.currentTime=0
                audio_element.play()
            }
            return audio_element
        }
    }
</script>

After that you can initialize as many audio as you like:

<script type="text/javascript" >
    var clicksound  = ss_soundbits('your/path/to/click.ogg', "your/path/to/click.mp3");
    var plopsound  = ss_soundbits('your/path/to/plopp.ogg', "your/path/to/plopp.mp3");
</script>

Now you can reach the initialized audio element whereever you like with simple event calls like

onclick="clicksound.playclip()"

onmouseover="plopsound.playclip()"

Here is a simple clean version that I use: link

I had run "python setup.py install" at some point in the past accidentally in my global environment, and had much difficulty uninstalling. These solutions didn't help. "pip uninstall " didn't work with "Can't uninstall 'splunk-appinspect'. No files were found to uninstall." "sudo pip uninstall " didn't work "Cannot uninstall requirement splunk-appinspect, not installed". I tried uninstalling pip, deleting the pip cache, searching my hard drive for the package, etc...

"pip show " eventually led me to the solution, the "Location:" was pointing to a directory, and renaming that directory caused the packaged to be removed from pip's list. I renamed the directory back, and it didn't reappear in pip's list, and now I can reinstall my package in a virtualenv.

If the device you're trying to interact with is a physical phone connected via USB, you can unplug it and plug it back and and it should work. Sometimes it just gets out of sync I think.

You're not saying how exactly putdata() is not behaving. I'm assuming you're doing

>>> pic.putdata(a)
Traceback (most recent call last):
  File "...blablabla.../PIL/Image.py", line 1185, in putdata
    self.im.putdata(data, scale, offset)
SystemError: new style getargs format but argument is not a tuple

This is because putdata expects a sequence of tuples and you're giving it a numpy array. This

>>> data = list(tuple(pixel) for pixel in pix)
>>> pic.putdata(data)

will work but it is very slow.

As of PIL 1.1.6, the "proper" way to convert between images and numpy arrays is simply

>>> pix = numpy.array(pic)

although the resulting array is in a different format than yours (3-d array or rows/columns/rgb in this case).

Then, after you make your changes to the array, you should be able to do either pic.putdata(pix) or create a new image with Image.fromarray(pix).

Quick answer : Add proxy configuration with parameter for both install/update

gem install --http-proxy http://host:port/ package_name

gem update --http-proxy http://host:port/ package_name

If you are using babel, you bind 'this' using ES7 bind operator https://babeljs.io/docs/en/babel-plugin-transform-function-bind#auto-self-binding

export default class SignupPage extends React.Component {
  constructor(props) {
    super(props);
  }

  handleSubmit(e) {
    e.preventDefault(); 

    const data = { 
      email: this.refs.email.value,
    } 
  }

  render() {

    const {errors} = this.props;

    return (
      <div className="view-container registrations new">
        <main>
          <form id="sign_up_form" onSubmit={::this.handleSubmit}>
            <div className="field">
              <input ref="email" id="user_email" type="email" placeholder="Email"  />
            </div>
            <div className="field">
              <input ref="password" id="user_password" type="new-password" placeholder="Password"  />
            </div>
            <button type="submit">Sign up</button>
          </form>
        </main>
      </div>
    )
  }

}

Can be achieved also with scriptrunner

ScriptRunner.exe -appvscript demoA.cmd arg1 arg2 -appvscriptrunnerparameters -wait -timeout=30 -rollbackonerror -appvscript demoB.ps1 arg3 arg4 -appvscriptrunnerparameters -wait -timeout=30 

Which also have some features as rollback , timeout and waiting.

You can maintain a Map (for fast lookup) and List (for order) but a LinkedHashMap may be the simplest. You can also try a SortedMap e.g. TreeMap, which an have any order you specify.

For Linux Mint

I had the same issue whilst using PhpBrew ( 5.5.9 / 7.0.14 ) and trying to create a PDO connection.

After I had tried most of the solutions on this post I did the following:

1. Powered off PhpBrew

2. Executed sudo apt-get install php7.0 (Linux Mint 17.2 / PHP7.0.16) - installed fresh php version

You can use this https://github.com/advancedrei/BootstrapForEmail for b-strapping your email.

A possible workaround that allows to enable database session timeout without an external scheduled task is to use the extension pg_timeout that I have developped.

You could use Regex.Split:

string[] tokens = Regex.Split(input, @"\r?\n|\r");

Edit: added |\r to account for (older) Mac line terminators.

Here's a nice function template using C++11 magic, working for both std::map, std::unordered_map:

template<template <typename...> class MAP, class KEY, class VALUE>
std::vector<KEY>
keys(const MAP<KEY, VALUE>& map)
{
    std::vector<KEY> result;
    result.reserve(map.size());
    for(const auto& it : map){
        result.emplace_back(it.first);
    }
    return result;
}

While it is a bit of an overkill for just sorting a single array, this prototype function allows to sort Javascript arrays by any key, in ascending or descending order, including nested keys, using dot syntax.

(function(){
    var keyPaths = [];

    var saveKeyPath = function(path) {
        keyPaths.push({
            sign: (path[0] === '+' || path[0] === '-')? parseInt(path.shift()+1) : 1,
            path: path
        });
    };

    var valueOf = function(object, path) {
        var ptr = object;
        for (var i=0,l=path.length; i<l; i++) ptr = ptr[path[i]];
        return ptr;
    };

    var comparer = function(a, b) {
        for (var i = 0, l = keyPaths.length; i < l; i++) {
            aVal = valueOf(a, keyPaths[i].path);
            bVal = valueOf(b, keyPaths[i].path);
            if (aVal > bVal) return keyPaths[i].sign;
            if (aVal < bVal) return -keyPaths[i].sign;
        }
        return 0;
    };

    Array.prototype.sortBy = function() {
        keyPaths = [];
        for (var i=0,l=arguments.length; i<l; i++) {
            switch (typeof(arguments[i])) {
                case "object": saveKeyPath(arguments[i]); break;
                case "string": saveKeyPath(arguments[i].match(/[+-]|[^.]+/g)); break;
            }
        }
        return this.sort(comparer);
    };    
})();

Usage:

var data = [
    { name: { first: 'Josh', last: 'Jones' }, age: 30 },
    { name: { first: 'Carlos', last: 'Jacques' }, age: 19 },
    { name: { first: 'Carlos', last: 'Dante' }, age: 23 },
    { name: { first: 'Tim', last: 'Marley' }, age: 9 },
    { name: { first: 'Courtney', last: 'Smith' }, age: 27 },
    { name: { first: 'Bob', last: 'Smith' }, age: 30 }
]

data.sortBy('age'); // "Tim Marley(9)", "Carlos Jacques(19)", "Carlos Dante(23)", "Courtney Smith(27)", "Josh Jones(30)", "Bob Smith(30)"

Sorting by nested properties with dot-syntax or array-syntax:

data.sortBy('name.first'); // "Bob Smith(30)", "Carlos Dante(23)", "Carlos Jacques(19)", "Courtney Smith(27)", "Josh Jones(30)", "Tim Marley(9)"
data.sortBy(['name', 'first']); // "Bob Smith(30)", "Carlos Dante(23)", "Carlos Jacques(19)", "Courtney Smith(27)", "Josh Jones(30)", "Tim Marley(9)"

Sorting by multiple keys:

data.sortBy('name.first', 'age'); // "Bob Smith(30)", "Carlos Jacques(19)", "Carlos Dante(23)", "Courtney Smith(27)", "Josh Jones(30)", "Tim Marley(9)"
data.sortBy('name.first', '-age'); // "Bob Smith(30)", "Carlos Dante(23)", "Carlos Jacques(19)", "Courtney Smith(27)", "Josh Jones(30)", "Tim Marley(9)"

Very simple code to make jquery slider Here is two div first is the slider viewer and second is the image list container. Just copy paste the code and customise with css.

    <div class="featured-image" style="height:300px">
     <img id="thumbnail" src="01.jpg"/>
    </div>

    <div class="post-margin" style="margin:10px 0px; padding:0px;" id="thumblist">
    <img src='01.jpg'>
    <img src='02.jpg'>
    <img src='03.jpg'>
    <img src='04.jpg'>
    </div>

    <script type="text/javascript">
            function changeThumbnail()
            {
            $("#thumbnail").fadeOut(200);
            var path=$("#thumbnail").attr('src');
            var arr= new Array(); var i=0;
            $("#thumblist img").each(function(index, element) {
               arr[i]=$(this).attr('src');
               i++;
            });
            var index= arr.indexOf(path);
            if(index==(arr.length-1))
            path=arr[0];
            else
            path=arr[index+1];
            $("#thumbnail").attr('src',path).fadeIn(200);
            setTimeout(changeThumbnail, 5000);  
            }
            setTimeout(changeThumbnail, 5000);
    </script>

Authentication issue: I use TortoiseGit GUI tool, I need to tell tortoise the username and password so that it can access to work with Git/GitHub/Gitlab code base. To tell it, rt click inside any folder to get TortoiseGit menu. Here TortoseGit > Settings Window > Select Credentials in left nav tree Enter URL:Git url Helper: Select windows if your windows credentials are same as the ones for Git or 'manager' if they are different userName; Git User Name Save this settings ans try again. You will be prompted for password and then it worked.

If the "many" model does not justify the creation of a model per-se (not the case here, but it might benefits other people), another alternative would be to rely on specific PostgreSQL data types, via the Django Contrib package

Postgres can deal with Array or JSON data types, and this may be a nice workaround to handle One-To-Many when the many-ies can only be tied to a single entity of the one.

Postgres allows you to access single elements of the array, which means that queries can be really fast, and avoid application-level overheads. And of course, Django implements a cool API to leverage this feature.

It obviously has the disadvantage of not being portable to others database backend, but I thougt it still worth mentionning.

Hope it may help some people looking for ideas.

Try this:

$('element').attr('id', 'value');

So it becomes;

$(function() {
    $('span .breadcrumb').each(function(){
        $('#nav').attr('id', $(this).text());
        $('#container').attr('id', $(this).text());
        $('.stretch_footer').attr('id', $(this).text())
        $('#footer').attr('id', $(this).text());
    });
});

So you are changing/overwriting the id of three elements and adding an id to one element. You can modify as per you needs...

If you want the two divs to be displayed one above the other, the simplest answer is to remove the float: left;from the css declaration, as this causes them to collapse to the size of their contents (or the css defined size), and, well float up against each other.

Alternatively, you could simply add clear:both; to the divs, which will force the floated content to clear previous floats.

The li tag has a property called list-style-position. This makes your bullets inside or outside the list. On default, it’s set to inside. That makes your text wrap around it. If you set it to outside, the text of your li tags will be aligned.

The downside of that is that your bullets won't be aligned with the text outside the ul. If you want to align it with the other text you can use a margin.

ul li {
    /*
     * We want the bullets outside of the list,
     * so the text is aligned. Now the actual bullet
     * is outside of the list’s container
     */
    list-style-position: outside;

    /*
     * Because the bullet is outside of the list’s
     * container, indent the list entirely
     */
    margin-left: 1em;
}

Edit 15th of March, 2014 Seeing people are still coming in from Google, I felt like the original answer could use some improvement

• Changed the code block to provide just the solution
• Changed the indentation unit to em’s
• Each property is applied to the ul element
• Good comments :)

Try this:

yAxis: {min: 0, max: 100}

See this jsfiddle example

In my case, I was in the platform-tools directory but was using command in the wrong way:

adb install

instead of the right way:

./adb install

the position:fixed; property should do the work, I used it on my Website and it worked fine. http://www.w3schools.com/css/css_positioning.asp

In order to uninstall miniconda, simply remove the miniconda folder,

rm -r ~/miniconda/

As for avoiding conflicts between different Python environments, you can use virtual environments. In particular, with Miniconda, the following workflow could be used,

$ wget https://repo.continuum.io/miniconda/Miniconda3-3.7.0-Linux-x86_64.sh -O ~/miniconda.sh
$ bash miniconda
$ conda env remove --yes -n new_env    # remove the environement new_env if it exists (optional)
$ conda create --yes -n new_env pip numpy pandas scipy matplotlib scikit-learn nltk ipython-notebook seaborn python=2
$ activate new_env
$ # pip install modules if needed, run python scripts, etc
  # everything will be installed in the new_env
  # located in ~/miniconda/envs/new_env
$ deactivate

RecyclerView was created as a ListView improvement, so yes, you can create an attached list with ListView control, but using RecyclerView is easier as it:

1. Reuses cells while scrolling up/down - this is possible with implementing View Holder in the ListView adapter, but it was an optional thing, while in the RecycleView it's the default way of writing adapter.

2. Decouples list from its container - so you can put list items easily at run time in the different containers (linearLayout, gridLayout) with setting LayoutManager.

Example:

mRecyclerView = (RecyclerView) findViewById(R.id.my_recycler_view);
mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
//or
mRecyclerView.setLayoutManager(new GridLayoutManager(this, 2));

3. Animates common list actions - Animations are decoupled and delegated to ItemAnimator.

There is more about RecyclerView, but I think these points are the main ones.

So, to conclude, RecyclerView is a more flexible control for handling "list data" that follows patterns of delegation of concerns and leaves for itself only one task - recycling items.

At its core, Git is a set of command line utility programs that are designed to execute on a Unix style command-line environment. Modern operating systems like Linux and macOS both include built-in Unix command line terminals. This makes Linux and macOS complementary operating systems when working with Git. Microsoft Windows instead uses Windows command prompt, a non-Unix terminal environment.

What is Git Bash?

Git Bash is an application for Microsoft Windows environments which provides an emulation layer for a Git command line experience. Bash is an acronym for Bourne Again Shell. A shell is a terminal application used to interface with an operating system through written commands. Bash is a popular default shell on Linux and macOS. Git Bash is a package that installs Bash, some common bash utilities, and Git on a Windows operating system.

Some people are suggesting specific plug-ins and/or browsers. I would not because they're only really useful for that one platform; a test run on Firefox will not translate accurately to IE7. Considering 99.999999% of sites have more than one browser visit them, you need to check performance on all the popular platforms.

My suggestion would be to keep this in the JS. Create a benchmarking page with all your JS test on and time the execution. You could even have it AJAX-post the results back to you to keep it fully automated.

Then just rinse and repeat over different platforms.

SELECT * from Employee 
WHERE Salary IN (SELECT MAX(Salary) 
                 FROM Employee 
                 WHERE Salary NOT IN (SELECT MAX(Salary) 
                                      FFROM employee));

Try like this..

If your abstract class contains concrete functionality that has business value, then I will usually test it directly by creating a test double that stubs out the abstract data, or by using a mocking framework to do this for me. Which one I choose depends a lot on whether I need to write test-specific implementations of the abstract methods or not.

The most common scenario in which I need to do this is when I'm using the Template Method pattern, such as when I'm building some sort of extensible framework that will be used by a 3rd party. In this case, the abstract class is what defines the algorithm that I want to test, so it makes more sense to test the abstract base than a specific implementation.

However, I think it's important that these tests should focus on the concrete implementations of real business logic only; you shouldn't unit test implementation details of the abstract class because you'll end up with brittle tests.

Need to set the foreign key option as on delete cascade... in tables which contains foreign key columns.... It need to set at the time of table creation or add later using ALTER table

If you want to keep alias at the global level as is and just want to change for your script.

Just use:

alias cp=cp

and then write your follow up commands.

#include <iostream>
#include <type_traits>

using namespace std;

enum class A {
  a = 1,
  b = 69,
  c= 666
};

std::ostream& operator << (std::ostream& os, const A& obj)
{
   os << static_cast<std::underlying_type<A>::type>(obj);
   return os;
}

int main () {
  A a = A::c;
  cout << a << endl;
}

git pull = git fetch + git merge origin/branch

git pull and git pull origin branch only differ in that the latter will only "update" origin/branch and not all origin/* as git pull does.

git pull origin/branch will just not work because it's trying to do a git fetch origin/branch which is invalid.

Question related: git fetch + git merge origin/master vs git pull origin/master

Yes, you can store any object (I assume you are using ASP.NET with default settings, which is in-process session state):

Session["test"] = myList;

You should cast it back to the original type for use:

var list = (List<int>)Session["test"];
// list.Add(something);

As Richard points out, you should take extra care if you are using other session state modes (e.g. SQL Server) that require objects to be serializable.

They are just totally different. Consider this example of a volatile integer:

volatile int i = 0;
void incIBy5() {
    i += 5;
}

If two threads call the function concurrently, i might be 5 afterwards, since the compiled code will be somewhat similar to this (except you cannot synchronize on int):

void incIBy5() {
    int temp;
    synchronized(i) { temp = i }
    synchronized(i) { i = temp + 5 }
}

If a variable is volatile, every atomic access to it is synchronized, but it is not always obvious what actually qualifies as an atomic access. With an Atomic* object, it is guaranteed that every method is "atomic".

Thus, if you use an AtomicInteger and getAndAdd(int delta), you can be sure that the result will be 10. In the same way, if two threads both negate a boolean variable concurrently, with an AtomicBoolean you can be sure it has the original value afterwards, with a volatile boolean, you can't.

So whenever you have more than one thread modifying a field, you need to make it atomic or use explicit synchronization.

The purpose of volatile is a different one. Consider this example

volatile boolean stop = false;
void loop() {
    while (!stop) { ... }
}
void stop() { stop = true; }

If you have a thread running loop() and another thread calling stop(), you might run into an infinite loop if you omit volatile, since the first thread might cache the value of stop. Here, the volatile serves as a hint to the compiler to be a bit more careful with optimizations.

You can combine this all into one formula, but you need to use a regular IF first to find out if the VLOOKUP came back with something, then use your COUNTIF if it did.

=IF(ISERROR(VLOOKUP(B1,Sheet2!A1:A9,1,FALSE)),"Not there",COUNTIF(Sheet2!A1:A9,B1))

In this case, Sheet2-A1:A9 is the range I was searching, and Sheet1-B1 had the value I was looking for ("To retire" in your case).

For understanding templates, it's of huge advantage to get the terminology straight because the way you speak about them determines the way to think about them.

Specifically, Area is not a template class, but a class template. That is, it is a template from which classes can be generated. Area<int> is such a class (it's not an object, but of course you can create an object from that class in the same ways you can create objects from any other class). Another such class would be Area<char>. Note that those are completely different classes, which have nothing in common except for the fact that they were generated from the same class template.

Since Area is not a class, you cannot derive the class Rectangle from it. You only can derive a class from another class (or several of them). Since Area<int> is a class, you could, for example, derive Rectangle from it:

class Rectangle:
  public Area<int>
{
  // ...
};

Since Area<int> and Area<char> are different classes, you can even derive from both at the same time (however when accessing members of them, you'll have to deal with ambiguities):

class Rectangle:
  public Area<int>,
  public Area<char>
{
  // ...
};

However you have to specify which classed to derive from when you define Rectangle. This is true no matter whether those classes are generated from a template or not. Two objects of the same class simply cannot have different inheritance hierarchies.

What you can do is to make Rectangle a template as well. If you write

template<typename T> class Rectangle:
  public Area<T>
{
  // ...
};

You have a template Rectangle from which you can get a class Rectangle<int> which derives from Area<int>, and a different class Rectangle<char> which derives from Area<char>.

It may be that you want to have a single type Rectangle so that you can pass all sorts of Rectangle to the same function (which itself doesn't need to know the Area type). Since the Rectangle<T> classes generated by instantiating the template Rectangle are formally independent of each other, it doesn't work that way. However you can make use of multiple inheritance here:

class Rectangle // not inheriting from any Area type
{
  // Area independent interface
};

template<typename T> class SpecificRectangle:
  public Rectangle,
  public Area<T>
{
  // Area dependent stuff
};

void foo(Rectangle&); // A function which works with generic rectangles

int main()
{
  SpecificRectangle<int> intrect;
  foo(intrect);

  SpecificRectangle<char> charrect;
  foo(charrect);
}

If it is important that your generic Rectangle is derived from a generic Area you can do the same trick with Area too:

class Area
{
  // generic Area interface
};

class Rectangle:
  public virtual Area // virtual because of "diamond inheritance"
{
  // generic rectangle interface
};

template<typename T> class SpecificArea:
  public virtual Area
{
  // specific implementation of Area for type T
};

template<typename T> class SpecificRectangle:
  public Rectangle, // maybe this should be virtual as well, in case the hierarchy is extended later
  public SpecificArea<T> // no virtual inheritance needed here
{
  // specific implementation of Rectangle for type T
};

cursor:url('http://www.javascriptkit.com/dhtmltutors/cursor-hand.gif'), auto

NOTE 1: In some cases you should consider setting the offset (anchor):

cursor:url(http://www.javascriptkit.com/dhtmltutors/cursor-hand.gif) 10 3, auto;

in this exmple, we set offsetx to 10 and offsety to 3 (from top left), so the pointer finger will be anchor. fiddle: http://jsfiddle.net/5kxt1j98/ (you can see the difference by moving cursor to top left of container)

NOTE 2: THE MAX CURSOR SIZE IS 128*128, recommended one is below 32*32.

I used AndExplorer for this purpose and my solution is popup a dialog and then redirect on the market to install the misssing application:

My startCreation is trying to call external file/directory picker. If it is missing call show installResultMessage function.

private void startCreation(){
    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_PICK);
    Uri startDir = Uri.fromFile(new File("/sdcard"));

    intent.setDataAndType(startDir,
            "vnd.android.cursor.dir/lysesoft.andexplorer.file");
    intent.putExtra("browser_filter_extension_whitelist", "*.csv");
    intent.putExtra("explorer_title", getText(R.string.andex_file_selection_title));
    intent.putExtra("browser_title_background_color",
            getText(R.string.browser_title_background_color));
    intent.putExtra("browser_title_foreground_color",
            getText(R.string.browser_title_foreground_color));
    intent.putExtra("browser_list_background_color",
            getText(R.string.browser_list_background_color));
    intent.putExtra("browser_list_fontscale", "120%");
    intent.putExtra("browser_list_layout", "2");

    try{
         ApplicationInfo info = getPackageManager()
                                 .getApplicationInfo("lysesoft.andexplorer", 0 );

            startActivityForResult(intent, PICK_REQUEST_CODE);
    } catch( PackageManager.NameNotFoundException e ){
        showInstallResultMessage(R.string.error_install_andexplorer);
    } catch (Exception e) {
        Log.w(TAG, e.getMessage());
    }
}

This methos is just pick up a dialog and if user wants install the external application from market

private void showInstallResultMessage(int msg_id) {
    AlertDialog dialog = new AlertDialog.Builder(this).create();
    dialog.setMessage(getText(msg_id));
    dialog.setButton(getText(R.string.button_ok),
            new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    finish();
                }
            });
    dialog.setButton2(getText(R.string.button_install),
            new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    Intent intent = new Intent(Intent.ACTION_VIEW);
                    intent.setData(Uri.parse("market://details?id=lysesoft.andexplorer"));
                    startActivity(intent);
                    finish();
                }
            });
    dialog.show();
}

A map-reduce solution:

var urlParams = location.search.split(/[?&]/).slice(1).map(function(paramPair) {
        return paramPair.split(/=(.+)?/).slice(0, 2);
    }).reduce(function (obj, pairArray) {            
        obj[pairArray[0]] = pairArray[1];
        return obj;
    }, {});

Usage:

For url: http://example.com?one=1&two=2
console.log(urlParams.one) // 1
console.log(urlParams.two) // 2

To save memory, do not unnecessarily store/duplicate the data in memory (i.e. do not assign them to variables outside the loop). Just process the output immediately as soon as the input comes in.

It really doesn't matter whether you're using BufferedReader or not. It will not cost significantly much more memory as some implicitly seem to suggest. It will at highest only hit a few % from performance. The same applies on using NIO. It will only improve scalability, not memory use. It will only become interesting when you've hundreds of threads running on the same file.

Just loop through the file, write every line immediately to other file as you read in, count the lines and if it reaches 100, then switch to next file, etcetera.

Kickoff example:

String encoding = "UTF-8";
int maxlines = 100;
BufferedReader reader = null;
BufferedWriter writer = null;

try {
    reader = new BufferedReader(new InputStreamReader(new FileInputStream("/bigfile.txt"), encoding));
    int count = 0;
    for (String line; (line = reader.readLine()) != null;) {
        if (count++ % maxlines == 0) {
            close(writer);
            writer = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("/smallfile" + (count / maxlines) + ".txt"), encoding));
        }
        writer.write(line);
        writer.newLine();
    }
} finally {
    close(writer);
    close(reader);
}

? Splitting line in Python:

Have you tried using str.splitlines() method?:

• Python 2.X documentation here.
• Python 3.X documentation here.

From the docs:

str.splitlines([keepends])

Return a list of the lines in the string, breaking at line boundaries. Line breaks are not included in the resulting list unless keepends is given and true.

For example:

>>> 'Line 1\n\nLine 3\rLine 4\r\n'.splitlines()
['Line 1', '', 'Line 3', 'Line 4']

>>> 'Line 1\n\nLine 3\rLine 4\r\n'.splitlines(True)
['Line 1\n', '\n', 'Line 3\r', 'Line 4\r\n']

Which delimiters are considered?

This method uses the universal newlines approach to splitting lines.

The main difference between Python 2.X and Python 3.X is that the former uses the universal newlines approach to splitting lines, so "\r", "\n", and "\r\n" are considered line boundaries for 8-bit strings, while the latter uses a superset of it that also includes:

• \v or \x0b: Line Tabulation (added in Python 3.2).
• \f or \x0c: Form Feed (added in Python 3.2).
• \x1c: File Separator.
• \x1d: Group Separator.
• \x1e: Record Separator.
• \x85: Next Line (C1 Control Code).
• \u2028: Line Separator.
• \u2029: Paragraph Separator.

splitlines VS split:

Unlike str.split() when a delimiter string sep is given, this method returns an empty list for the empty string, and a terminal line break does not result in an extra line:

>>> ''.splitlines()
[]

>>> 'Line 1\n'.splitlines()
['Line 1']

While str.split('\n') returns:

>>> ''.split('\n')
['']

>>> 'Line 1\n'.split('\n')
['Line 1', '']

?? Removing additional whitespace:

If you also need to remove additional leading or trailing whitespace, like spaces, that are ignored by str.splitlines(), you could use str.splitlines() together with str.strip():

>>> [str.strip() for str in 'Line 1  \n  \nLine 3 \rLine 4 \r\n'.splitlines()]
['Line 1', '', 'Line 3', 'Line 4']

? Removing empty strings (''):

Lastly, if you want to filter out the empty strings from the resulting list, you could use filter():

>>> # Python 2.X:
>>> filter(bool, 'Line 1\n\nLine 3\rLine 4\r\n'.splitlines())
['Line 1', 'Line 3', 'Line 4']

>>> # Python 3.X:
>>> list(filter(bool, 'Line 1\n\nLine 3\rLine 4\r\n'.splitlines()))
['Line 1', 'Line 3', 'Line 4']

Additional comment regarding the original question:

As the error you posted indicates and Burhan suggested, the problem is from the print. There's a related question about that could be useful to you: UnicodeEncodeError: 'charmap' codec can't encode - character maps to <undefined>, print function

If, for example, x = 5 and is stored as string, you can also just:

x = x + 0

and the new x would be stored as a numeric value.

SELECT  DISTINCT *
FROM    people
WHERE   names = 'Smith'
ORDER BY
        names
LIMIT 10

Editing or overriding the row in Twitter bootstrap is a bad idea, because this is a core part of the page scaffolding and you will need rows without a top margin.

To solve this, instead create a new class "top-buffer" that adds the standard margin that you need.

.top-buffer { margin-top:20px; }

And then use it on the row divs where you need a top margin.

<div class="row top-buffer"> ...

It is all but satisfying, isn't it? The easiest way I have found to specify when setting the context, e.g.:

sns.set_context("paper", rc={"font.size":8,"axes.titlesize":8,"axes.labelsize":5})   

This should take care of 90% of standard plotting usage. If you want ticklabels smaller than axes labels, set the 'axes.labelsize' to the smaller (ticklabel) value and specify axis labels (or other custom elements) manually, e.g.:

axs.set_ylabel('mylabel',size=6)

you could define it as a function and load it in your scripts so you don't have to remember your standard numbers, or call it every time.

def set_pubfig:
    sns.set_context("paper", rc={"font.size":8,"axes.titlesize":8,"axes.labelsize":5})   

Of course you can use configuration files, but I guess the whole idea is to have a simple, straightforward method, which is why the above works well.

Note: If you specify these numbers, specifying font_scale in sns.set_context is ignored for all specified font elements, even if you set it.

In this case, using WebView#loadDataWithBaseUrl() is better than WebView#loadUrl()!

webView.loadDataWithBaseURL(url, 
        data,
        "text/html",
        "utf-8",
        null);

url: url/path String pointing to the directory all your JavaScript files and html links have their origin. If null, it's about:blank. data: String containing your hmtl file, read with BufferedReader for example

More info: WebView.loadDataWithBaseURL(java.lang.String, java.lang.String, java.lang.String, java.lang.String, java.lang.String)

This should help in most of the cases (you need to install sshpass first!):

#!/usr/bin/bash
read -p 'Enter Your Username: ' UserName;
read -p 'Enter Your Password: ' Password;
read -p 'Enter Your Domain Name: ' Domain;

sshpass -p "$Password" ssh -o StrictHostKeyChecking=no $UserName@$Domain

I also had this error.

My IIS Website has a Default Website with three (3) application directories below it.

I had each of my 3 application directories configured correctly to use .NET Framework v2.0 in the Application Pools.

However, the Default Website never was configured. I didn't think it was necessary since all of my apps were contained within it.

My IIS Server's default configuration is .NET Framework v4.0, so I changed that to .NET v2.0:

After I did that, I no longer received the same error message.

Now, I see this:

I hope this information helps others.

The most compact version:

<input type="submit" onclick="return confirm('Are you sure?')" />

The key thing to note is the return

-

Because there are many ways to skin a cat, here is another alternate method:

HTML:

<input type="submit" onclick="clicked(event)" />

Javascript:

<script>
function clicked(e)
{
    if(!confirm('Are you sure?')) {
        e.preventDefault();
    }
}
</script>

You are trying to access the class as opposed to the object. That statement can be confusing to beginners, but you are effectively trying to open your house door by picking up the door on your house plans.

If you actually wanted to access the form components directly from a class (which you don't) you would use the variable that instantiates your form.

Depending on which way you want to go you'd be better of either sending the text of a control or whatever to a method in your classes eg

public void DoSomethingWithText(string formText)
{
   // do something text in here
}

or exposing properties on your form class and setting the form text in there - eg

string SomeProperty
{
   get 
   {
      return textBox1.Text;
   }
   set
   {
      textBox1.Text = value;
   }
}

You need to add the python executable path to your Window's PATH variable.

1. From the desktop, right-click My Computer and click Properties.
2. In the System Properties window, click on the Advanced tab.
3. In the Advanced section, click the Environment Variables button.
4. Highlight the Path variable in the Systems Variable section and click the Edit button.
5. Add the path of your python executable(c:\Python27\). Each different directory is separated with a semicolon. (Note: do not put spaces between elements in the PATH. Your addition to the PATH should read ;c:\Python27 NOT ; C\Python27)
6. Apply the changes. You might need to restart your system, though simply restarting cmd.exe should be sufficient.
7. Launch cmd and try again. It should work.

To view the file, run:

xxd filename | less

To use Vim as a hex editor:

1. Open the file in Vim.
2. Run :%!xxd (transform buffer to hex)
3. Edit.
4. Run :%!xxd -r (reverse transformation)
5. Save.

it's file:///android_asset/... not file:///android_assets/... notice the plural of assets is wrong even if your file name is assets

Just want to share with what I used so far to save your time.

Here are examples of hard-coded headers and dynamic headers (in case if don't care about data structure). In both cases I wrote some simple directive: customSort

          '</a>',
        link: function(scope) {

        // change sorting order
        scope.sort_by = function(newSortingOrder) {       
            var sort = scope.sort;

            if (sort.sortingOrder == newSortingOrder){
                sort.reverse = !sort.reverse;
            }                    

            sort.sortingOrder = newSortingOrder;        
        };


        scope.selectedCls = function(column) {
            if(column == scope.sort.sortingOrder){
                return ('icon-chevron-' + ((scope.sort.reverse) ? 'down' : 'up'));
            }
            else{            
                return'icon-sort' 
            } 
        };      
      }// end link
    }
    });

[1st option with static headers]

As a side note:

The ng-bind-html-unsafe is deprecated, so I used it only for Demo (2nd example). You welcome to edit.

I believe my input is controlled since it has a value.

For an input to be controlled, its value must correspond to that of a state variable.

That condition is not initially met in your example because this.state.name is not initially set. Therefore, the input is initially uncontrolled. Once the onChange handler is triggered for the first time, this.state.name gets set. At that point, the above condition is satisfied and the input is considered to be controlled. This transition from uncontrolled to controlled produces the error seen above.

By initializing this.state.name in the constructor:

e.g.

this.state = { name: '' };

the input will be controlled from the start, fixing the issue. See React Controlled Components for more examples.

Unrelated to this error, you should only have one default export. Your code above has two.

you can make your own regular expression for javascript validation

    /^            : Start
    (?=.{8,})        : Length
    (?=.*[a-zA-Z])   : Letters
    (?=.*\d)         : Digits
    (?=.*[!#$%&? "]) : Special characters
    $/              : End



        (/^
        (?=.*\d)                //should contain at least one digit
        (?=.*[a-z])             //should contain at least one lower case
        (?=.*[A-Z])             //should contain at least one upper case
        [a-zA-Z0-9]{8,}         //should contain at least 8 from the mentioned characters

        $/)

Example:-   /^(?=.*\d)(?=.*[a-zA-Z])[a-zA-Z0-9]{7,}$/

To remove newlines, use tr:

tr -d '\n'

If you want to replace each newline with a single space:

tr '\n' ' '

The error ba: Event not found is coming from csh, and is due to csh trying to match !ba in your history list. You can escape the ! and write the command:

sed ':a;N;$\!ba;s/\n/ /g'  # Suitable for csh only!!

but sed is the wrong tool for this, and you would be better off using a shell that handles quoted strings more reasonably. That is, stop using csh and start using bash.

Session.Abandon() destroys the session and the Session_OnEnd event is triggered.

Session.Clear() just removes all values (content) from the Object. The session with the same key is still alive.

So, if you use Session.Abandon(), you lose that specific session and the user will get a new session key. You could use it for example when the user logs out.

Use Session.Clear(), if you want that the user remaining in the same session (if you don't want him to relogin for example) and reset all his session specific data.

You are looking for collections.defaultdict (available for Python 2.5+). This

from collections import defaultdict

my_dict = defaultdict(int)
my_dict[key] += 1

will do what you want.

For regular Python dicts, if there is no value for a given key, you will not get None when accessing the dict -- a KeyError will be raised. So if you want to use a regular dict, instead of your code you would use

if key in my_dict:
    my_dict[key] += 1
else:
    my_dict[key] = 1

public dynamic ViewBag
{
    get
    {
        if (_viewBag == null)
        {

        }

        return _viewBag;
    }
}

Using jQuery it is very simple assuming the URL you wish to post to is on the same server or has implemented CORS

$(function() {
  $("#employeeLink").on("click",function(e) {
    e.preventDefault(); // cancel the link itself
    $.post(this.href,function(data) {
      $("#someContainer").html(data);
    });
  });
});

If you insist on using frames which I strongly discourage, have a form and submit it with the link

<form action="employee.action" method="post" target="myFrame" id="myForm"></form>

and use (in plain JS)

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the link
     document.getElementById("myForm").submit(); // but make sure nothing has name or ID="submit"
   });
 });

Without a form we need to make one

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the actual link
     var myForm = document.createElement("form");
     myForm.action=this.href;// the href of the link
     myForm.target="myFrame";
     myForm.method="POST";
     myForm.submit();
   });
 });

To find files which are created in last one hour in current directory, you can use -amin

find . -amin -60 -type f

This will find files which are created with in last 1 hour.

In the constructor of the Form or UserControl holding the TextBox write

SetStyle(ControlStyles.Selectable, false);

After the InitializeComponent(); Source: https://stackoverflow.com/a/4811938/5750078

Example:

public partial class Main : UserControl
{

    public Main()
    {
        InitializeComponent();
        SetStyle(ControlStyles.Selectable, false);
    }

I had the same problem. I eventually figured it out by inspecting the element and the element I thought I had selected was different element. When I did that I found there was a hidden element that had z-index of 9999, once I fixed that my problem went away.

The value returned by hashCode() is the object's hash code, which is the object's memory address in hexadecimal.

By definition, if two objects are equal, their hash code must also be equal. If you override the equals() method, you change the way two objects are equated and Object's implementation of hashCode() is no longer valid. Therefore, if you override the equals() method, you must also override the hashCode() method as well.

This answer is from the java SE 8 official tutorial documentation

Here is how I do it. This way I can actually get a function to simulate returning multiple values;

function foo($array) 
{ 
    foreach($array as $_key => $_value) 
    {
       $str .= "{$_key}=".$_value.'&';
    }
    return $str = substr($str, 0, -1);
} 

/* Set the variables to pass to function, in an Array */

    $waffles['variable1'] = "value1"; 
    $waffles['variable2'] = "value2"; 
    $waffles['variable3'] = "value3"; 

/* Call Function */

    parse_str( foo( $waffles ));

/* Function returns multiple variable/value pairs */

    echo $variable1 ."<br>";
    echo $variable2 ."<br>";
    echo $variable3 ."<br>";

Especially usefull if you want, for example all fields in a database to be returned as variables, named the same as the database table fields. See 'db_fields( )' function below.

For example, if you have a query

select login, password, email from members_table where id = $id

Function returns multiple variables:

$login, $password and $email

Here is the function:

function db_fields($field, $filter, $filter_by,  $table = 'members_table') {

 /*
    This function will return as variable names, all fields that you request, 
    and the field values assigned to the variables as variable values.  

    $filter_by = TABLE FIELD TO FILTER RESULTS BY
    $filter =  VALUE TO FILTER BY
    $table = TABLE TO RUN QUERY AGAINST

    Returns single string value or ARRAY, based on whether user requests single
    field or multiple fields.

    We return all fields as variable names. If multiple rows
    are returned, check is_array($return_field); If > 0, it contains multiple rows.
    In that case, simply run parse_str($return_value) for each Array Item. 
*/
    $field = ($field == "*") ? "*,*" : $field;
    $fields = explode(",",$field);

    $assoc_array = ( count($fields) > 0 ) ? 1 : 0;

    if (!$assoc_array) {
        $result = mysql_fetch_assoc(mysql_query("select $field from $table where $filter_by = '$filter'"));
        return ${$field} = $result[$field];
    }
    else
    {
        $query = mysql_query("select $field from $table where $filter_by = '$filter'");
        while ($row = mysql_fetch_assoc($query)) {
            foreach($row as $_key => $_value) {
                $str .= "{$_key}=".$_value.'&';
            }
            return $str = substr($str, 0, -1);
        }
    }
}

Below is a sample call to function. So, If we need to get User Data for say $user_id = 12345, from the members table with fields ID, LOGIN, PASSWORD, EMAIL:

$filter = $user_id;
$filter_by = "ID";
$table_name = "members_table"

parse_str(db_fields('LOGIN, PASSWORD, EMAIL', $filter, $filter_by, $table_name));

/* This will return the following variables: */

echo $LOGIN ."<br>";
echo $PASSWORD ."<br>";
echo $EMAIL ."<br>";

We could also call like this:

parse_str(db_fields('*', $filter, $filter_by, $table_name));

The above call would return all fields as variable names.

If the Path is omitted the file will be saved automaticaly in the current directory. Try something like this:

ActiveWorkbook.SaveAs "Filename.xslx"

I have solved it this way.

Go to your project file let's say project/name/bin and delete everything within the bin folder. (this will then give you another error which you can solve this way)

then in your visual studio right click project's References folder, to open NuGet Package Manager.

Go to browse and install "DotNetCompilerPlatform".

Converting a varchar value into an int fails when the value includes a decimal point to prevent loss of data.

If you convert to a decimal or float value first, then convert to int, the conversion works.

Either example below will return 7082:

SELECT CONVERT(int, CONVERT(decimal(12,7), '7082.7758172'));
SELECT CAST(CAST('7082.7758172' as float) as int);

Be aware that converting to a float value may result, in rare circumstances, in a loss of precision. I would tend towards using a decimal value, however you'll need to specify precision and scale values that make sense for the varchar data you're converting.

Figure sizes are specified in inches and can be included as a global option of the document output format. For example:

---
title: "My Document"
output:
  html_document:
    fig_width: 6
    fig_height: 4
---

And the plot's size in the graphic device can be increased at the chunk level:

```{r, fig.width=14, fig.height=12}          #Expand the plot width to 14 inches

ggplot(aes(x=mycolumn1, y=mycolumn2)) +     #specify the x and y aesthetic
geom_line(size=2) +                         #makes the line thicker
theme_grey(base_size = 25)                  #increases the size of the font
```

You can also use the out.width and out.height arguments to directly define the size of the plot in the output file:

```{r, out.width="200px", out.height="200px"} #Expand the plot width to 200 pixels

ggplot(aes(x=mycolumn1, y=mycolumn2)) +     #specify the x and y aesthetic
geom_line(size=2) +                         #makes the line thicker
theme_grey(base_size = 25)                  #increases the size of the font
```

I fought with this one for a while. My goal was to have a table with headers where the widths of the each header column was the the same as the corresponding body column and was the minimum size necessary to fit the data. also the body data was scrollable underneath header.

I solved this by using divs and not tables. Each "table" was a div with the header being a div of divs and the body being a div of divs. I used the style as indicated by @sushil above. I added a bit of javascript/jQuery to balance the columns. Maybe 20-30 lines.

Unfortunately I lost the code and have to rebuild it. I know this is a bit old, but maybe it will help someone else.

Just for completeness: You can pass slice a vector of indices:

df %>% arrange(stopSequence) %>% group_by(id) %>% slice(c(1,n()))

which gives

  id stopId stopSequence
1  1      a            1
2  1      c            3
3  2      b            1
4  2      c            4
5  3      b            1
6  3      a            3

I think the most correct answer, assuming the use of jQuery, is a consolidation of aspects of all the answers in this page, plus the use of the event that Bootstrap passes:

$(document).on('shown.bs.modal', function(e) {
  $('input:visible:enabled:first', e.target).focus();
});

It also would work changing $(document) to $('.modal') or to add a class to the modal that signals that this focus should occur, like $('.modal.focus-on-first-input')

You could use id in (select id from ...) or id in (select id from ...)

e.g. instead of non-working

from Person p where p.name="Joe"
union
from Person p join p.children c where c.name="Joe"

you could do

from Person p 
  where p.id in (select p1.id from Person p1 where p1.name="Joe") 
    or p.id in (select p2.id from Person p2 join p2.children c where c.name="Joe");

At least using MySQL, you will run into performance problems with it later, though. It's sometimes easier to do a poor man's join on two queries instead:

// use set for uniqueness
Set<Person> people = new HashSet<Person>((List<Person>) query1.list());
people.addAll((List<Person>) query2.list());
return new ArrayList<Person>(people);

It's often better to do two simple queries than one complex one.

EDIT:

to give an example, here is the EXPLAIN output of the resulting MySQL query from the subselect solution:

mysql> explain 
  select p.* from PERSON p 
    where p.id in (select p1.id from PERSON p1 where p1.name = "Joe") 
      or p.id in (select p2.id from PERSON p2 
        join CHILDREN c on p2.id = c.parent where c.name="Joe") \G

Slightly modified from: Python Pandas Dataframe: Normalize data between 0.01 and 0.99? but from some of the comments thought it was relevant (sorry if considered a repost though...)

I wanted customized normalization in that regular percentile of datum or z-score was not adequate. Sometimes I knew what the feasible max and min of the population were, and therefore wanted to define it other than my sample, or a different midpoint, or whatever! This can often be useful for rescaling and normalizing data for neural nets where you may want all inputs between 0 and 1, but some of your data may need to be scaled in a more customized way... because percentiles and stdevs assumes your sample covers the population, but sometimes we know this isn't true. It was also very useful for me when visualizing data in heatmaps. So i built a custom function (used extra steps in the code here to make it as readable as possible):

def NormData(s,low='min',center='mid',hi='max',insideout=False,shrinkfactor=0.):    
    if low=='min':
        low=min(s)
    elif low=='abs':
        low=max(abs(min(s)),abs(max(s)))*-1.#sign(min(s))
    if hi=='max':
        hi=max(s)
    elif hi=='abs':
        hi=max(abs(min(s)),abs(max(s)))*1.#sign(max(s))

    if center=='mid':
        center=(max(s)+min(s))/2
    elif center=='avg':
        center=mean(s)
    elif center=='median':
        center=median(s)

    s2=[x-center for x in s]
    hi=hi-center
    low=low-center
    center=0.

    r=[]

    for x in s2:
        if x<low:
            r.append(0.)
        elif x>hi:
            r.append(1.)
        else:
            if x>=center:
                r.append((x-center)/(hi-center)*0.5+0.5)
            else:
                r.append((x-low)/(center-low)*0.5+0.)

    if insideout==True:
        ir=[(1.-abs(z-0.5)*2.) for z in r]
        r=ir

    rr =[x-(x-0.5)*shrinkfactor for x in r]    
    return rr

This will take in a pandas series, or even just a list and normalize it to your specified low, center, and high points. also there is a shrink factor! to allow you to scale down the data away from endpoints 0 and 1 (I had to do this when combining colormaps in matplotlib:Single pcolormesh with more than one colormap using Matplotlib) So you can likely see how the code works, but basically say you have values [-5,1,10] in a sample, but want to normalize based on a range of -7 to 7 (so anything above 7, our "10" is treated as a 7 effectively) with a midpoint of 2, but shrink it to fit a 256 RGB colormap:

#In[1]
NormData([-5,2,10],low=-7,center=1,hi=7,shrinkfactor=2./256)
#Out[1]
[0.1279296875, 0.5826822916666667, 0.99609375]

It can also turn your data inside out... this may seem odd, but I found it useful for heatmapping. Say you want a darker color for values closer to 0 rather than hi/low. You could heatmap based on normalized data where insideout=True:

#In[2]
NormData([-5,2,10],low=-7,center=1,hi=7,insideout=True,shrinkfactor=2./256)
#Out[2]
[0.251953125, 0.8307291666666666, 0.00390625]

So now "2" which is closest to the center, defined as "1" is the highest value.

Anyways, I thought my application was relevant if you're looking to rescale data in other ways that could have useful applications to you.

There is a lot of confusion here, especially if you read outdated sources.

The basic one is Activity, which can show Fragments. You can use this combination if you're on Android version > 4.

However, there is also a support library which encompasses the other classes you mentioned: FragmentActivity, ActionBarActivity and AppCompat. Originally they were used to support fragments on Android versions < 4, but actually they're also used to backport functionality from newer versions of Android (material design for example).

The latest one is AppCompat, the other 2 are older. The strategy I use is to always use AppCompat, so that the app will be ready in case of backports from future versions of Android.

From man githooks:

pre-commit
This hook is invoked by git commit, and can be bypassed with --no-verify option. It takes no parameter, and is invoked before obtaining the proposed commit log message and making a commit. Exiting with non-zero status from this script causes the git commit to abort.

<?xml version="1.0" encoding="UTF-8"?>

Notes:

• Put the following content in your configuration file.
• Name the configuration file log4j2.xml
• Put the log4j2.xml in a folder which is in the class-path (i.e. your source folder "src")
• Use Logger logger = LogManager.getLogger(); to initialize your logger
• I did set the immediateFlush="false" since this is better for SSD lifetime. If you need the log right away in your log-file remove the parameter or set it to true

Use TimeSpan.Parse to convert the string

http://msdn.microsoft.com/en-us/library/system.timespan.parse(v=vs.110).aspx

There is built in functionality for this using the JavaScriptSerializer Class:

var json = JavaScriptSerializer.Serialize(data);

You can do one of the following:

<?php
    $data = 'My data';

    function menugen() {
        global $data;
        echo "[" . $data . "]";
    }

    menugen();

Or

<?php
    $data = 'My data';

    function menugen() {
        echo "[" . $GLOBALS['data'] . "]";
    }

    menugen();

That being said, overuse of globals can lead to some poor code. It is usually better to pass in what you need. For example, instead of referencing a global database object you should pass in a handle to the database and act upon that. This is called dependency injection. It makes your life a lot easier when you implement automated testing (which you should).

int main()
{
  int array[11];
  printf("Write down your ID number!\n");
  for(int i=0;i<id_length;i++)
  scanf("%d", &array[i]);
  if (array[0]==1)
  {
    printf("\nThis person is a male.");
  }
  else if (array[0]==2)
  {
    printf("\nThis person is a female.");
  }
  return 0;
}

Found another small problem with this code... or at least it was problematic when I tried to implement it.

The buttons in frmMain do not return a compatible value, using VS2010 I added the following and everything started working fine.

public static ResultFromFrmMain Execute() {
     using (var f = new frmMain()) {

          f.buttonOK.DialogResult = DialogResult.OK;
          f.buttonCancel.DialogResult = DialogResult.Cancel;

          var result = new ResultFromFrmMain();
          result.Result = f.ShowDialog();

          if (result.Result == DialogResult.OK) {
             // fill other values
          }
          return result;
     }
}

After adding the two button values, the dialog worked great! Thanks for the example, it really helped.

We also had to develop a solution which would even work with APIs requiring authentication (see this article)

Using AngularJS in a nutshell here is how we did it:

Step 1: Create a dedicated directive

// jQuery needed, uses Bootstrap classes, adjust the path of templateUrl
app.directive('pdfDownload', function() {
return {
    restrict: 'E',
    templateUrl: '/path/to/pdfDownload.tpl.html',
    scope: true,
    link: function(scope, element, attr) {
        var anchor = element.children()[0];

        // When the download starts, disable the link
        scope.$on('download-start', function() {
            $(anchor).attr('disabled', 'disabled');
        });

        // When the download finishes, attach the data to the link. Enable the link and change its appearance.
        scope.$on('downloaded', function(event, data) {
            $(anchor).attr({
                href: 'data:application/pdf;base64,' + data,
                download: attr.filename
            })
                .removeAttr('disabled')
                .text('Save')
                .removeClass('btn-primary')
                .addClass('btn-success');

            // Also overwrite the download pdf function to do nothing.
            scope.downloadPdf = function() {
            };
        });
    },
    controller: ['$scope', '$attrs', '$http', function($scope, $attrs, $http) {
        $scope.downloadPdf = function() {
            $scope.$emit('download-start');
            $http.get($attrs.url).then(function(response) {
                $scope.$emit('downloaded', response.data);
            });
        };
    }] 
});

Step 2: Create a template

<a href="" class="btn btn-primary" ng-click="downloadPdf()">Download</a>

Step 3: Use it

<pdf-download url="/some/path/to/a.pdf" filename="my-awesome-pdf"></pdf-download>

This will render a blue button. When clicked, a PDF will be downloaded (Caution: the backend has to deliver the PDF in Base64 encoding!) and put into the href. The button turns green and switches the text to Save. The user can click again and will be presented with a standard download file dialog for the file my-awesome.pdf.

Our example uses PDF files, but apparently you could provide any binary format given it's properly encoded.

I think it's a historical thing - if a package is introduced as an addition to an existing JRE, it comes in as javax. If it's first introduced as part of a JRE (like NIO was, I believe) then it comes in as java. Not sure why the new date and time API will end up as javax following this logic though... unless it will also be available separately as a library to work with earlier versions (which would be useful). Note from many years later: it actually ended up being in java after all.

I believe there are restrictions on the java package - I think classloaders are set up to only allow classes within java.* to be loaded from rt.jar or something similar. (There's certainly a check in ClassLoader.preDefineClass.)

EDIT: While an official explanation (the search orbfish suggested didn't yield one in the first page or so) is no doubt about "core" vs "extension", I still suspect that in many cases the decision for any particular package has an historical reason behind it too. Is java.beans really that "core" to Java, for example?

I decided to just make a video for this..I kept pasting it into tools but alas that was not working for me. I moved it to platform-tools and voila publishing right away..must restart eclipse afterwards.

Tutorial for fixing missing zipalign

As already pointed out, b += 1 updates b in-place, while a = a + 1 computes a + 1 and then assigns the name a to the result (now a does not refer to a row of A anymore).

To understand the += operator properly though, we need also to understand the concept of mutable versus immutable objects. Consider what happens when we leave out the .reshape:

C = np.arange(12)
for c in C:
    c += 1
print(C)  # [ 0  1  2  3  4  5  6  7  8  9 10 11]

We see that C is not updated, meaning that c += 1 and c = c + 1 are equivalent. This is because now C is a 1D array (C.ndim == 1), and so when iterating over C, each integer element is pulled out and assigned to c.

Now in Python, integers are immutable, meaning that in-place updates are not allowed, effectively transforming c += 1 into c = c + 1, where c now refers to a new integer, not coupled to C in any way. When you loop over the reshaped arrays, whole rows (np.ndarray's) are assigned to b (and a) at a time, which are mutable objects, meaning that you are allowed to stick in new integers at will, which happens when you do a += 1.

It should be mentioned that though + and += are meant to be related as described above (and very much usually are), any type can implement them any way it wants by defining the __add__ and __iadd__ methods, respectively.

Both @Collin Jackson and @Sniper are right. You can follow these steps to set up launch images in android and iOS respectively. Then in your MyApp(), in your initState(), you can use Future.delayed to set up a timer or call any api. Until the response is returned from the Future, your launch icons will be shown and then as the response come, you can move to the screen you want to go to after the splash screen. You can see this link : Flutter Splash Screen

Try out this Card

Card(
    elevation: 10,
    shape: RoundedRectangleBorder(
      borderRadius: BorderRadius.circular(25.0), // half of height and width of Image
      ),
    child: Image.asset(
      "assets/images/home.png",
      width: 50,
      height: 50,
    ),
  )

To add up on the answer, I used this at the beginning of the needed script. So it runs smoothly on different environments.

import os
import matplotlib as mpl
if os.environ.get('DISPLAY','') == '':
    print('no display found. Using non-interactive Agg backend')
    mpl.use('Agg')
import matplotlib.pyplot as plt

Because I didn't want it to be alsways using the 'Agg' backend, only when it would go through Travis CI for example.

Only this worked for me:

#container:hover .cube { background-color: yellow; }

Where .cube is CssClass of the #cube.

Tested in Firefox, Chrome and Edge.

import numpy as np
import matplotlib.pyplot as plt 
from scipy import stats

x = np.array([1.5,2,2.5,3,3.5,4,4.5,5,5.5,6])
y = np.array([10.35,12.3,13,14.0,16,17,18.2,20,20.7,22.5])
gradient, intercept, r_value, p_value, std_err = stats.linregress(x,y)
mn=np.min(x)
mx=np.max(x)
x1=np.linspace(mn,mx,500)
y1=gradient*x1+intercept
plt.plot(x,y,'ob')
plt.plot(x1,y1,'-r')
plt.show()

If I read the JSONArray constructors correctly, you can build them from any Collection (arrayList is a subclass of Collection) like so:

ArrayList<String> list = new ArrayList<String>();
list.add("foo");
list.add("baar");
JSONArray jsArray = new JSONArray(list);

References:

• collection: http://developer.android.com/reference/java/util/Collection.html

=arrayformula(if(isblank(B2:B),iferror(1/0),mmult(sign(B2:B=TRANSPOSE(A2:A)),A2:A)))

I got this from a good tutorial - can't remember the title - probably about using MMult

For those who's interested in functional style, or looks for more expressive approach to utilize in meta programming (such as type checking), it could be interesting to see Ramda library to accomplish such task.

Next code contains only pure and pointfree functions:

const R = require('ramda');

const isPrototypeEquals = R.pipe(Object.getPrototypeOf, R.equals);

const equalsSyncFunction = isPrototypeEquals(() => {});

const isSyncFunction = R.pipe(Object.getPrototypeOf, equalsSyncFunction);

As of ES2017, async functions are available, so we can check against them as well:

const equalsAsyncFunction = isPrototypeEquals(async () => {});

const isAsyncFunction = R.pipe(Object.getPrototypeOf, equalsAsyncFunction);

And then combine them together:

const isFunction = R.either(isSyncFunction, isAsyncFunction);

Of course, function should be protected against null and undefined values, so to make it "safe":

const safeIsFunction = R.unless(R.isNil, isFunction);

And, complete snippet to sum up:

const R = require('ramda');

const isPrototypeEquals = R.pipe(Object.getPrototypeOf, R.equals);

const equalsSyncFunction = isPrototypeEquals(() => {});
const equalsAsyncFunction = isPrototypeEquals(async () => {});

const isSyncFunction = R.pipe(Object.getPrototypeOf, equalsSyncFunction);
const isAsyncFunction = R.pipe(Object.getPrototypeOf, equalsAsyncFunction);

const isFunction = R.either(isSyncFunction, isAsyncFunction);

const safeIsFunction = R.unless(R.isNil, isFunction);

// ---

console.log(safeIsFunction( function () {} ));
console.log(safeIsFunction( () => {} ));
console.log(safeIsFunction( (async () => {}) ));
console.log(safeIsFunction( new class {} ));
console.log(safeIsFunction( {} ));
console.log(safeIsFunction( [] ));
console.log(safeIsFunction( 'a' ));
console.log(safeIsFunction( 1 ));
console.log(safeIsFunction( null ));
console.log(safeIsFunction( undefined ));

However, note the this solution could show less performance than other available options due to extensive usage of higher-order functions.

your id attribute is not set. this MAY be due to the fact that the DB field is not set to auto increment? what DB are you using? MySQL? is your field set to AUTO INCREMENT?

Your question is a little unclear, but if what you're doing is trying to get your friend's latest changes, then typically what your friend needs to do is to push those changes up to a remote repo (like one hosted on GitHub), and then you fetch or pull those changes from the remote:

1. Your friend pushes his changes to GitHub:

   git push origin <branch>
   

2. Clone the remote repository if you haven't already:

   git clone https://[email protected]/abc/theproject.git
   

3. Fetch or pull your friend's changes (unnecessary if you just cloned in step #2 above):

   git fetch origin
   git merge origin/<branch>
   

   Note that git pull is the same as doing the two steps above:

   git pull origin <branch>

Any time you need to separate allocation from initialization, you'll need placement new and explicit calling of the destructor manually. Today, it's rarely necessary, since we have the standard containers, but if you have to implement some new sort of container, you'll need it.

With ES6 you can do it with a simple one-liner

const If = ({children, show}) => show ? children : null

"show" is a boolean and you use this class by

<If show={true}> Will show </If>
<If show={false}> WON'T show </div> </If>

I Had the same problem and finally reached to the solution.

add "--stacktrace --debug" to your command-line options(File -> Settings -> Compiler) then run it. This will show the problem(unwanted code) in your code.
