If you're open to out-of-the-DB solution: You could set up a cron job that runs a script that will itself call the procedure.

You'll have to make a join:

SELECT A.SalesOrderID, B.Foo
FROM A
JOIN B bo ON bo.id = (
     SELECT TOP 1 id
     FROM B bi
     WHERE bi.SalesOrderID = a.SalesOrderID
     ORDER BY bi.whatever
     )
WHERE A.Date BETWEEN '2000-1-4' AND '2010-1-4'

, assuming that b.id is a PRIMARY KEY on B

In MS SQL 2005 and higher you may use this syntax:

SELECT SalesOrderID, Foo
FROM (
  SELECT A.SalesOrderId, B.Foo,
         ROW_NUMBER() OVER (PARTITION BY B.SalesOrderId ORDER BY B.whatever) AS rn
  FROM A
  JOIN B ON B.SalesOrderID = A.SalesOrderID
  WHERE A.Date BETWEEN '2000-1-4' AND '2010-1-4'
) i
WHERE rn

This will select exactly one record from B for each SalesOrderId.

Use StrictMode Something like this:-

   if (android.os.Build.VERSION.SDK_INT > 9) {
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();

        StrictMode.setThreadPolicy(policy); 
        }

Use theme():

d <- data.frame(x=gl(10, 1, 10, labels=paste("long text label ", letters[1:10])), y=rnorm(10))
ggplot(d, aes(x=x, y=y)) + geom_point() +
    theme(text = element_text(size=20),
        axis.text.x = element_text(angle=90, hjust=1)) 
#vjust adjust the vertical justification of the labels, which is often useful

There's lots of good information about how to format your ggplots here. You can see a full list of parameters you can modify (basically, all of them) using ?theme.

Use jdbc url as :

jdbc:mysql://localhost:3306/Database_dbName?allowPublicKeyRetrieval=true&useSSL=false;

PortNo: 3306 can be different in your configuation

git status --short | grep "^UU "

Adding alternative base R approach, which remains fast under various cases.

rowsummean <- function(df) {
  rowsum(df$speed, df$dive) / tabulate(df$dive)
}

Borrowing the benchmarks from @Ari:

10 rows, 2 groups

10 million rows, 10 groups

10 million rows, 1000 groups

The innerHTML property is part of the Document Object Model (DOM) that allows Javascript code to manipulate a website being displayed. Specifically, it allows reading and replacing everything within a given DOM element (HTML tag).

However, DOM manipulations using innerHTML are slower and more failure-prone than manipulations based on individual DOM objects.

I usually used to make a function:

function getMonth(monthStr){
    return new Date(monthStr+'-1-01').getMonth()+1
}

And call it like :

getMonth('Jan');
getMonth('Feb');
getMonth('Dec');

Unless I am misunderstanding, you can just add height: 100%; and overflow:hidden; to #down.

#down { 
    background:pink; 
    height:100%; 
    overflow:hidden;
}?

Live DEMO

Edit: Since you do not want to use overflow:hidden;, you can use display: table; for this scenario; however, it is not supported prior to IE 8. (display: table; support)

#container { 
    width: 300px; 
    height: 300px; 
    border:1px solid red;
    display:table;
}

#up { 
    background: green;
    display:table-row;
    height:0; 
}

#down { 
    background:pink;
    display:table-row;
}?

Live DEMO

Note: You have said that you want the #down height to be #container height minus #up height. The display:table; solution does exactly that and this jsfiddle will portray that pretty clearly.

The best way I have found is to use jQuery JSON

Alternatively, create a figure() object using the figsize argument and then use add_subplot to add your subplots. E.g.

import matplotlib.pyplot as plt
import numpy as np

f = plt.figure(figsize=(10,3))
ax = f.add_subplot(121)
ax2 = f.add_subplot(122)
x = np.linspace(0,4,1000)
ax.plot(x, np.sin(x))
ax2.plot(x, np.cos(x), 'r:')

Benefits of this method are that the syntax is closer to calls of subplot() instead of subplots(). E.g. subplots doesn't seem to support using a GridSpec for controlling the spacing of the subplots, but both subplot() and add_subplot() do.

If your variable is the percentage:

var myWidth = 70;
$('div#somediv').width(myWidth + '%');

If your variable is in pixels, and you want the percentage it take up of the parent:

var myWidth = 140;
var myPercentage = (myWidth / $('div#somediv').parent().width()) * 100;
$('div#somediv').width(myPercentage + '%');

Regarding de-duping things your string split and match is great first cut. If there are known items about the data that can be leveraged to reduce workload and/or produce better results, it is always good to take advantage of them. Bear in mind that often for de-duping it is impossible to entirely eliminate manual work, although you can make that much easier by catching as much as you can automatically and then generating reports of your "uncertainty cases."

Regarding name matching: SOUNDEX is horrible for quality of matching and especially bad for the type of work you are trying to do as it will match things that are too far from the target. It's better to use a combination of double metaphone results and the Levenshtein distance to perform name matching. With appropriate biasing this works really well and could probably be used for a second pass after doing a cleanup on your knowns.

You may also want to consider using an SSIS package and looking into Fuzzy Lookup and Grouping transformations (http://msdn.microsoft.com/en-us/library/ms345128(SQL.90).aspx).

Using SQL Full-Text Search (http://msdn.microsoft.com/en-us/library/cc879300.aspx) is a possibility as well, but is likely not appropriate to your specific problem domain.

Reason of the error: Package name left blank while creating a class. This make use of default package. Thus causes this error.

Quick fix:

1. Create a package eg. helloWorld inside the src folder.
2. Move helloWorld.java file in that package. Just drag and drop on the package. Error should disappear.

Explanation:

• My Eclipse version: 2020-09 (4.17.0)
• My Java version: Java 15, 2020-09-15

Latest version of Eclipse required java11 or above. The module feature is introduced in java9 and onward. It was proposed in 2005 for Java7 but later suspended. Java is object oriented based. And module is the moduler approach which can be seen in language like C. It was harder to implement it, due to which it took long time for the release. Source: Understanding Java 9 Modules

When you create a new project in Eclipse then by default module feature is selected. And in Eclipse-2020-09-R, a pop-up appears which ask for creation of module-info.java file. If you select don't create then module-info.java will not create and your project will free from this issue.

Best practice is while crating project, after giving project name. Click on next button instead of finish. On next page at the bottom it ask for creation of module-info.java file. Select or deselect as per need.

If selected: (by default) click on finish button and give name for module. Now while creating a class don't forget to give package name. Whenever you create a class just give package name. Any name, just don't left it blank.

If deselect: No issue

For pre PHP 5:

function iso8601($time=false) {
    if(!$time) $time=time();
    return date("Y-m-d", $time) . 'T' . date("H:i:s", $time) .'+00:00';
}

Chris Lea provides a YUM repository for python26 RPMs that can co-exist with the 'native' 2.4 that is needed for quite a few admin tools on CentOS.

Quick instructions that worked at least for me:

$ sudo rpm -Uvh http://yum.chrislea.com/centos/5/i386/chl-release-5-3.noarch.rpm
$ sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-CHL
$ sudo yum install python26
$ python26

I've recently built a tool for this that does just this... It fetches a directory asynchronously and returns a list of items. You can either get directories, files or both, with folders being first. You can also paginate the data in case where you don't want to fetch the entire folder.

This is the link, hope it helps someone!

null and undefined are both false for value equality (null==undefined): they both collapse to boolean false. They are not the same object (null!==undefined).

undefined is a property of the global object ("window" in browsers), but is a primitive type and not an object itself. It's the default value for uninitialized variables and functions ending without a return statement.

null is an instance of Object. null is used for DOM methods that return collection objects to indicate an empty result, which provides a false value without indicating an error.

Use can use one of below this

history.back();     // equivalent to clicking back button
history.go(-1);     // equivalent to history.back();

I am using as below for back button

<a class="btn btn-info float-right" onclick="history.back();" >Back</a>

I had a similar problem and I solved it by setting a static IP on the Android device.

When you add the network on Android, first you enter the SSID and password, then underneath you can open advanced options and set a static IP.

Aside from the (excellent) suggestion to use TikZ, you could use gastex. I used this before TikZ was available and it did its job too.

How I solved it.

1. Open project (!) "Properties", choose "Application", select targeting framework ".Net Framework 4.5"
2. Right click on your project -> Add reference
3. Make sure that in "Assemblies" -> "Extensions" option "System.Net.Http" is unchecked
4. Go to "Assemblies" -> "Framework" and select "System.Net.Http" and "System.Net.Http" options
5. That`s all!

In my case i had at the beginning .Net 4.0 and "Assemblies" -> "Extensions" option "System.Net.Http" with version 2.0.0.0. After my actions "Assemblies" -> "Framework" options "System.Net.Http" and "System.Net.Http" had the same 4.0.0.0 version.

FOR SQL SERVER

IF EXISTS(select * FROM sys.views where name = '')

You can use .on() to capture multiple events and then test for touch on the screen, e.g.:

$('#selector')
.on('touchstart mousedown', function(e){
  e.preventDefault();
  var touch = e.touches[0];
  if(touch){
    // Do some stuff
  }
  else {
    // Do some other stuff
  }
});

Try this:

function welcomeMessage()
{
    var shape1 = new Shape();
    //alert(shape1.draw());
    alert(shape1.hasOwnProperty("name"));
}

When working with reflection in JavaScript, member objects are always refered to as the name as a string. For example:

for(i in obj) { ... }

The loop iterator i will be hold a string value with the name of the property. To use that in code you have to address the property using the array operator like this:

 for(i in obj) {
   alert("The value of obj." + i + " = " + obj[i]);
 }

EG : COMPARE TO VILLAGE NAME

ALTER PROCEDURE POSMAST
(@COLUMN_NAME VARCHAR(50))
AS
SELECT * FROM TABLE_NAME
WHERE 
village_name LIKE + @VILLAGE_NAME + '%';

On Windows it ended up being that the port was already in use by IIS.

Stopping IIS (Right-click, Exit), resolved the issue.

Right Click On Project -> Open Module Settings -> Click SDK's

Choose Java Home Directory

Any reason you cannot just change it on the object directly? It is not as if javascript enforces visibility of a property on an object.

You can communicate with docker from inside of a container using unix socket via Docker Remote API:

https://docs.docker.com/engine/reference/api/docker_remote_api/

In a container, you can find out a shortedned docker id by examining $HOSTNAME env var. According to doc, there is a small chance of collision, I think that for small number of container, you do not have to worry about it. I don't know how to get full id directly.

You can inspect container similar way as outlined in banyan answer:

GET /containers/4abbef615af7/json HTTP/1.1

Response:

HTTP/1.1 200 OK
Content-Type: application/json

{
         "Id": "4abbef615af7......  ",
         "Created": "2013.....",
         ...
}

Alternatively, you can transfer docker id to the container in a file. The file is located on "mounted volume" so it is transfered to container:

docker run -t -i -cidfile /mydir/host1.txt -v /mydir:/mydir ubuntu /bin/bash

The docker id (shortened) will be in file /mydir/host1.txt in the container.

For me, the issue was that I mistakenly placed test cases in an internal class

[TestClass]
internal class TestLib {
}

That was causing test cases not being identified.

This website contains a much cleaner solution, it leaves pip intact as-well and one can easily switch between 3.5 and 3.6 and then whenever 3.7 is released.

http://ubuntuhandbook.org/index.php/2017/07/install-python-3-6-1-in-ubuntu-16-04-lts/

A short summary:

sudo apt-get install python python-pip python3 python3-pip
sudo add-apt-repository ppa:jonathonf/python-3.6
sudo apt-get update
sudo apt-get install python3.6
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 2

Then

$ pip -V
pip 8.1.1 from /usr/lib/python2.7/dist-packages (python 2.7)
$ pip3 -V
pip 8.1.1 from /usr/local/lib/python3.5/dist-packages (python 3.5)

Then to select python 3.6 run

sudo update-alternatives --config python3

and select '2'. Then

$ pip3 -V
pip 8.1.1 from /usr/local/lib/python3.6/dist-packages (python 3.6)

To update pip select the desired version and

pip3 install --upgrade pip

$ pip3 -V
pip 9.0.1 from /usr/local/lib/python3.6/dist-packages (python 3.6)

Tested on Ubuntu 16.04.

You'll have it all (with some plugins).

Btw, snippetsEmu is a nice tool for coding with useful snippets (like in TextMate). You can use (or modify) a pre-made package or make your own.

The current version of dialog has the option "dialogClass" which you can use with your id's. For example,

$('foo').dialog({dialogClass:'dialog_style1'});

Then the CSS would be

.dialog_style1 {color:#aaa;}

After 10 years :) . Without list comprehension

Return a single row of values from a select query like below.

"select name,userid, address from table1 where userid = 1"

json output

{ name : "name1", userid : 1, address : "adress1, street1" }

Code

cur.execute(f"select name,userid, address from table1 where userid = 1 ")
row = cur.fetchone()
desc = list(zip(*cur.description))[0]  #To get column names
rowdict = dict(zip(desc,row))
jsondict = jsonify(rowdict)  #Flask jsonify

cur.description is a tuple of tuples as below. unzip and zip to combine column name with values

(('name', None, None, None, None, None, None), ('userid', None, None, None, None, None, None), ('address', None, None, None, None, None, None))

To remove all OIDs from your database tables, you can use this Linux script:

First, login as PostgreSQL superuser:

sudo su postgres

Now run this script, changing YOUR_DATABASE_NAME with you database name:

for tbl in `psql -qAt -c "select schemaname || '.' || tablename from pg_tables WHERE schemaname <> 'pg_catalog' AND schemaname <> 'information_schema';" YOUR_DATABASE_NAME` ; do  psql -c "alter table $tbl SET WITHOUT OIDS" YOUR_DATABASE_NAME ; done

I used this script to remove all my OIDs, since Npgsql 3.0 doesn't work with this, and it isn't important to PostgreSQL anymore.

What system are you running on? Do you have access to some sort of debugger (gdb, visual studio's debugger, etc.)?

That would give us valuable information, like the line of code where the program crashes... Also, the amount of memory may be prohibitive.

Additionally, may I recommend that you replace the numeric limits by named definitions?

As such:

#define DIM1_SZ 1000
#define DIM2_SZ 1000000

Use those whenever you wish to refer to the array dimension limits. It will help avoid typing errors.

For Query parameters like domain.com/test?format=json&type=mini format, then you can easily receive it via - req.query.

app.get('/test', function(req, res){
  var format = req.query.format,
      type = req.query.type;
});

You need to apply the logo class to the image...then float the ul

I had also faced this issue. NO it will not affect your original repo by anyway. just simply delete it by entering the name of forked repo

tl;dr

cp -R "/src/project 1/App" "/src/project 2"

Explanation:

Using quotes will cater for spaces in the directory names

cp -R "/src/project 1/App" "/src/project 2"

If the App directory is specified in the destination directory:

cp -R "/src/project 1/App" "/src/project 2/App"

and "/src/project 2/App" already exists the result will be "/src/project 2/App/App"

Best not to specify the directory copied in the destination so that the command can be repeated over and over with the expected result.

Inside a bash script:

cp -R "${1}/App" "${2}"

I also experienced this problem and found the easy solution to be

public string ReturnValues()
{
    string _var = ""; // Setting an innitial value

    if (.....)  // Looking at conditions
    {
        _var = "true"; // Re-assign the value of _var
    }

    return _var; // Return the value of var
}

This also works with other return types and gives the least amount of problems

The initial value I chose was a fall-back value and I was able to re-assign the value as many times as required.

It would be ideal if you could set parameters on the same line as your call to start Node.js on Windows. Look at the following carefully, and run it exactly as stated:

You have these two options:

1. At the command line:

   set NODE_ENV=production&&npm start
   

   or

   set NODE_ENV=production&&node index.js
   

2. The trick for it to work on Windows is you need to remove the whitespace before and after the "&&". Configured your package.json file with start_windows (see below) below. Then Run "npm run start_windows" at the command line.

   //package.json
   
   "scripts": {
     "start": "node index.js"
     "start_windows": "set NODE_ENV=production&&node index.js"
   }
   

In oficial documentation https://github.com/mde/ejs#includes show that includes works like that:

<%- include('../partials/head') %>

You probably want something like:

if data.find('!masters') != -1:
     f = open('masters.txt')
     lines = f.read().splitlines()
     f.close()
     for line in lines:
         print line
         sck.send('PRIVMSG ' + chan + " " + str(line) + '\r\n')

Don't close it every iteration of the loop and print line instead of lines. Also use readlines to get all the lines.

EDIT removed my other answer - the other one in this discussion is a better alternative than what I had, so there's no reason to copy it.

Also stripped off the \n with read().splitlines()

Just had the same problem here. In my case, the bat files had space " " After getting rid of spaces from filename and change into underscore, bat file worked

You just need Visual C++ runtime 2015 installed, if you change your php version to the newest version you will get the error for it. this is why apache has php dependency error.

Regarding “thought leaders”: Linus emphatically advocates line wrapping for the full commit message:

[…] we use 72-character columns for word-wrapping, except for quoted material that has a specific line format.

The exceptions refers mainly to “non-prose” text, that is, text that was not typed by a human for the commit — for example, compiler error messages.

Java prevent E notation in a double:

Five different ways to convert a double to a normal number:

import java.math.BigDecimal;
import java.text.DecimalFormat;

public class Runner {
    public static void main(String[] args) {
        double myvalue = 0.00000021d;

        //Option 1 Print bare double.
        System.out.println(myvalue);

        //Option2, use decimalFormat.
        DecimalFormat df = new DecimalFormat("#");
        df.setMaximumFractionDigits(8);
        System.out.println(df.format(myvalue));

        //Option 3, use printf.
        System.out.printf("%.9f", myvalue);
        System.out.println();

        //Option 4, convert toBigDecimal and ask for toPlainString().
        System.out.print(new BigDecimal(myvalue).toPlainString());
        System.out.println();

        //Option 5, String.format 
        System.out.println(String.format("%.12f", myvalue));
    }
}

This program prints:

2.1E-7
.00000021
0.000000210
0.000000210000000000000001085015324114868562332958390470594167709350585
0.000000210000

Which are all the same value.

Protip: If you are confused as to why those random digits appear beyond a certain threshold in the double value, this video explains: computerphile why does 0.1+0.2 equal 0.30000000000001?

It is a string formatting syntax (which it borrows from C).

Please see "PyFormat":

Python supports formatting values into strings. Although this can include very complicated expressions, the most basic usage is to insert values into a string with the %s placeholder.

Edit: Here is a really simple example:

#Python2
name = raw_input("who are you? ")
print "hello %s" % (name,)

#Python3+
name = input("who are you? ")
print("hello %s" % (name,))

The %s token allows me to insert (and potentially format) a string. Notice that the %s token is replaced by whatever I pass to the string after the % symbol. Notice also that I am using a tuple here as well (when you only have one string using a tuple is optional) to illustrate that multiple strings can be inserted and formatted in one statement.

When I need to keep the order, I use a list and a companion dict:

color = ['red','green','orange']
fruit = {'apple':0,'mango':1,'orange':2}
color[fruit['apple']]
for i in range(0,len(fruit)): # or len(color)
    color[i]

The inconvenience is I don't get easily the fruit from the index. When I need it, I use a tuple:

fruitcolor = [('apple','red'),('mango','green'),('orange','orange')]
index = {'apple':0,'mango':1,'orange':2}
fruitcolor[index['apple']][1]
for i in range(0,len(fruitcolor)): 
    fruitcolor[i][1]
for f, c in fruitcolor:
    c

Your data structures should be designed to fit your algorithm needs, so that it remains clean, readable and elegant.

There are a few different ways. If you want to do it yourself on the fly WMI is probably the way to go. RegistryKeyChangeEvent and its relatives are the ones to look at. There might be a way to monitor it through __InstanceCreationEvent, __InstanceDeletionEvent and __InstanceModificationEvent classes too.

For the sake of simplicity and to make it re-runnable, I have used a system StoredProcedure "sp_readerrorlog" to get data:

-----USING Table Variable
DECLARE @tblVar TABLE (
   LogDate DATETIME,
   ProcessInfo NVARCHAR(MAX),
   [Text] NVARCHAR(MAX)
)
INSERT INTO @tblVar Exec sp_readerrorlog
SELECT LogDate as DateOccured, ProcessInfo as pInfo, [Text] as Message FROM @tblVar



-----(OR): Using Temp Table
IF OBJECT_ID('tempdb..#temp') IS NOT NULL  DROP TABLE #temp;
CREATE TABLE #temp (
   LogDate DATETIME,
   ProcessInfo NVARCHAR(55),
   Text NVARCHAR(MAX)
)
INSERT INTO #temp EXEC sp_readerrorlog
SELECT * FROM #temp

So as another answer mentioned Guava has support for this by using:

Streams.stream(iterable);

I want to highlight that the implementation does something slightly different than other answers suggested. If the Iterable is of type Collection they cast it.

public static <T> Stream<T> stream(Iterable<T> iterable) {
  return (iterable instanceof Collection)
    ? ((Collection<T>) iterable).stream()
    : StreamSupport.stream(iterable.spliterator(), false);
}

public static <T> Stream<T> stream(Iterator<T> iterator) {
  return StreamSupport.stream(
    Spliterators.spliteratorUnknownSize(iterator, 0),
    false
  );
}

On strings and memory allocation:

A string in C is just a sequence of chars, so you can use char * or a char array wherever you want to use a string data type:

typedef struct     {
  int number;
  char *name;
  char *address;
  char *birthdate;
  char gender;
} patient;

Then you need to allocate memory for the structure itself, and for each of the strings:

patient *createPatient(int number, char *name, 
  char *addr, char *bd, char sex) {

  // Allocate memory for the pointers themselves and other elements
  // in the struct.
  patient *p = malloc(sizeof(struct patient));

  p->number = number; // Scalars (int, char, etc) can simply be copied

  // Must allocate memory for contents of pointers.  Here, strdup()
  // creates a new copy of name.  Another option:
  // p->name = malloc(strlen(name)+1);
  // strcpy(p->name, name);
  p->name = strdup(name);
  p->address = strdup(addr);
  p->birthdate = strdup(bd);
  p->gender = sex;
  return p;
}

If you'll only need a few patients, you can avoid the memory management at the expense of allocating more memory than you really need:

typedef struct     {
  int number;
  char name[50];       // Declaring an array will allocate the specified
  char address[200];   // amount of memory when the struct is created,
  char birthdate[50];  // but pre-determines the max length and may
  char gender;         // allocate more than you need.
} patient;

On linked lists:

In general, the purpose of a linked list is to prove quick access to an ordered collection of elements. If your llist contains an element called num (which presumably contains the patient number), you need an additional data structure to hold the actual patients themselves, and you'll need to look up the patient number every time.

Instead, if you declare

typedef struct llist
{
  patient *p;
  struct llist *next;
} list;

then each element contains a direct pointer to a patient structure, and you can access the data like this:

patient *getPatient(list *patients, int num) {
  list *l = patients;
  while (l != NULL) {
    if (l->p->num == num) {
      return l->p;
    }
    l = l->next;
  }
  return NULL;
}

How about using java.util.Arrays?

List<String> list = Arrays.asList((String[])jsonArray.toArray())

Here's another suggestion:

public interface Service<T> {
   T execute();
}

using this simple interface you can pass arguments via constructor in the concrete service classes:

public class FooService implements Service<String> {

    private final String input1;
    private final int input2;

    public FooService(String input1, int input2) {
       this.input1 = input1;
       this.input2 = input2;
    }

    @Override
    public String execute() {
        return String.format("'%s%d'", input1, input2);
    }
}

Do you really need that plugin? You can just animate the scrollTop property:

$("#nav ul li a[href^='#']").on('click', function(e) {

   // prevent default anchor click behavior
   e.preventDefault();

   // store hash
   var hash = this.hash;

   // animate
   $('html, body').animate({
       scrollTop: $(hash).offset().top
     }, 300, function(){

       // when done, add hash to url
       // (default click behaviour)
       window.location.hash = hash;
     });

});

First, I'm not certain that you need a second thread to set the shutdown_flag.
Why not set it directly in the SIGTERM handler?

An alternative is to raise an exception from the SIGTERM handler, which will be propagated up the stack. Assuming you've got proper exception handling (e.g. with with/contextmanager and try: ... finally: blocks) this should be a fairly graceful shutdown, similar to if you were to Ctrl+C your program.

Example program signals-test.py:

#!/usr/bin/python

from time import sleep
import signal
import sys


def sigterm_handler(_signo, _stack_frame):
    # Raises SystemExit(0):
    sys.exit(0)

if sys.argv[1] == "handle_signal":
    signal.signal(signal.SIGTERM, sigterm_handler)

try:
    print "Hello"
    i = 0
    while True:
        i += 1
        print "Iteration #%i" % i
        sleep(1)
finally:
    print "Goodbye"

Now see the Ctrl+C behaviour:

$ ./signals-test.py default
Hello
Iteration #1
Iteration #2
Iteration #3
Iteration #4
^CGoodbye
Traceback (most recent call last):
  File "./signals-test.py", line 21, in <module>
    sleep(1)
KeyboardInterrupt
$ echo $?
1

This time I send it SIGTERM after 4 iterations with kill $(ps aux | grep signals-test | awk '/python/ {print $2}'):

$ ./signals-test.py default
Hello
Iteration #1
Iteration #2
Iteration #3
Iteration #4
Terminated
$ echo $?
143

This time I enable my custom SIGTERM handler and send it SIGTERM:

$ ./signals-test.py handle_signal
Hello
Iteration #1
Iteration #2
Iteration #3
Iteration #4
Goodbye
$ echo $?
0

You can also use an exit variable if you want your code to be a bit more readable:

DECLARE @Flag int = 0
DECLARE @Done bit = 0

WHILE @Done = 0 BEGIN
    SET @Flag = @Flag + 1
    PRINT @Flag
    IF @Flag >= 5 SET @Done = 1
END

This would probably be more relevant when you have a more complicated loop and are trying to keep track of the logic. As stated loops are expensive so try and use other methods if you can.

You can use isset().

<form method="post">
    <input type="submit" name="test" id="test" value="RUN" />

</form>

<?php

function testfun()
{
   echo "Your test function on button click is working";
}

if(isset($_POST('submit')))
{
   testfun();
}

?>

The code runs much faster without using modulo:

public boolean isEven(int a){
    return ( (a & 1) == 0 );
}

public boolean isOdd(int a){
    return ( (a & 1) == 1 );
}

Is this what you had in mind?

$("document").ready( function() {
    // do your stuff
}

You can specify the whole day by doing a range, like so:

WHERE bk_date >= TO_DATE('2012-03-18', 'YYYY-MM-DD')
AND bk_date <  TO_DATE('2012-03-19', 'YYYY-MM-DD')

More simply you can use TRUNC:

WHERE TRUNC(bk_date) = TO_DATE('2012-03-18', 'YYYY-MM-DD')

TRUNC without parameter removes hours, minutes and seconds from a DATE.

You can try using the transform: translate property by passing the appropriate values inside the parenthesis using the inspect element in Google chrome.

You have to set translate property in such way that both the <div> overlap each other then You can use JavaScript to show and hide both the <div> according to your requirements

You could try this

Calendar today = Calendar.getInstance (); 
today.add(Calendar.DAY_OF_YEAR, 0); 
today.set(Calendar.HOUR_OF_DAY, hrs); 
today.set(Calendar.MINUTE, mins ); 
today.set(Calendar.SECOND, 0); 

and you could use today.getTime() to retrieve value and compare.

One easy step:

$ npm i -g npm-check-updates && ncu -u && npm i

That is all. All of the package versions in package.json will be the latest major versions.

Edit:

What is happening here?

1. Installing a package that checks updates for you.

2. Use this package to update all package versions in your package.json (-u is short for --updateAll).

3. Install all of the new versions of the packages.

I personally use Visual Leak Detector, though it can cause large delays when large blocks are leaked (it displays the contents of the entire leaked block).

I would generally prefer something a bit simpler, like activate/deactivate sub-resource (linked by a Link header with rel=service).

POST /groups/api/v1/groups/{group id}/activate

or

POST /groups/api/v1/groups/{group id}/deactivate

For the consumer, this interface is dead-simple, and it follows REST principles without bogging you down in conceptualizing "activations" as individual resources.

Unfortunately, I could not solve the problem with the other solution but my problem was that the branch name I want to push was not accepted by remote. I change it to the correct format and accepted.

it was test/testing_routes and needed to change it to testing_route which the / is not allowed by remote.

You should ensure that the branch name format is correct.

For curves with not too much noise, I recommend the following small code snippet:

from numpy import *

# example data with some peaks:
x = linspace(0,4,1e3)
data = .2*sin(10*x)+ exp(-abs(2-x)**2)

# that's the line, you need:
a = diff(sign(diff(data))).nonzero()[0] + 1 # local min+max
b = (diff(sign(diff(data))) > 0).nonzero()[0] + 1 # local min
c = (diff(sign(diff(data))) < 0).nonzero()[0] + 1 # local max


# graphical output...
from pylab import *
plot(x,data)
plot(x[b], data[b], "o", label="min")
plot(x[c], data[c], "o", label="max")
legend()
show()

The +1 is important, because diff reduces the original index number.

    Sdr = cmd.ExecuteReader();
    while (Sdr.Read())

        for (int i = 0; i < Sdr.FieldCount; i++)
        {
           comboID.Items.Add( Sdr.GetString(i));

        }
    }
    Sdr.Close();
    con.Close();

You need to include the reference to the assembly System.Web.Mvc in you project.

you may not have the System.Web.Mvc in your C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0

So you need to add it and then to include it as reference to your projrect

In the first two cases, you simply forgot to actually call the member function (!, it's not a value) std::vector<int>::size like this:

#include <vector>

int main () {
    std::vector<int> v;
    auto size = v.size();
}

Your third call

int size = v.size();

triggers a warning, as not every return value of that function (usually a 64 bit unsigned int) can be represented as a 32 bit signed int.

int size = static_cast<int>(v.size());

would always compile cleanly and also explicitly states that your conversion from std::vector::size_type to int was intended.

Note that if the size of the vector is greater than the biggest number an int can represent, size will contain an implementation defined (de facto garbage) value.

<strong> and <em> are abstract (which is what people mean when they say it's semantic). <b> and <i> are specific ways of making something "strong" or "emphasized"

Both <strong> is to <b> and <em> is to <i>

"vehicle" is to "jeep"

My case: configuring the service on new server. ASP.NET 4.0 was not installed/registered properly; svc extension was not recognized.

For me neither the MouseClick or Click event worked, because the events, simply, are not called when you right click. The quick way to do it is:

 private void button1_MouseUp(object sender, MouseEventArgs e)
 {
        if (e.Button == MouseButtons.Right)
        {
            //do something here
        }
        else//left or middle click
        {
            //do something here
        }
 }

You can modify that to do exactly what you want depended on the arguments' values.

WARNING: There is one catch with only using the mouse up event. if you mousedown on the control and then you move the cursor out of the control to release it, you still get the event fired. In order to avoid that, you should also make sure that the mouse up occurs within the control in the event handler. Checking whether the mouse cursor coordinates are within the control's rectangle before you check the buttons will do it properly.

For rails 4, based on this article and this original answer

Person
  .unscoped # See the caution note below. Maybe you want default scope here, in which case just remove this line.
  .where( # Begin a where clause
    where(:name => "John").where(:lastname => "Smith")  # join the scopes to be OR'd
    .where_values  # get an array of arel where clause conditions based on the chain thus far
    .inject(:or)  # inject the OR operator into the arels 
    # ^^ Inject may not work in Rails3. But this should work instead:
    .joins(" OR ")
    # ^^ Remember to only use .inject or .joins, not both
  )  # Resurface the arels inside the overarching query

Note the article's caution at the end:

Rails 4.1+

Rails 4.1 treats default_scope just as a regular scope. The default scope (if you have any) is included in the where_values result and inject(:or) will add or statement between the default scope and your wheres. That's bad.

To solve that, you just need to unscope the query.

This worked for me:

• download latest gem at https://rubygems.org/pages/download
• install the gem with gem install --local [path to downloaded gem file]
• update the gems with update_rubygems
• check that you're on the latest gem version with gem --version

Here's my simple vanilla JavaScript code:

let a = 'one,two,"three, but with a comma",four,"five, with ""quotes"" in it.."'
console.log(splitQuotes(a))

function splitQuotes(line) {
  if(line.indexOf('"') < 0) 
    return line.split(',')

  let result = [], cell = '', quote = false;
  for(let i = 0; i < line.length; i++) {
    char = line[i]
    if(char == '"' && line[i+1] == '"') {
      cell += char
      i++
    } else if(char == '"') {
      quote = !quote;
    } else if(!quote && char == ',') {
      result.push(cell)
      cell = ''
    } else {
      cell += char
    }
    if ( i == line.length-1 && cell) {
      result.push(cell)
    }
  }
  return result
}

Completely reset?

1. Delete the .git directory locally.

2. Recreate the git repostory:

   $ cd (project-directory)
   $ git init
   $ (add some files)
   $ git add .
   $ git commit -m 'Initial commit'
   

3. Push to remote server, overwriting. Remember you're going to mess everyone else up doing this … you better be the only client.

   $ git remote add origin <url>
   $ git push --force --set-upstream origin master
   

Do the following test:

Open a Command Prompt and type: tnsping instance_name

where instance_name is the name of the instance you want to connect (if it's a XE database, use "tnsping xe"

If it returns ok, follow steps of Der Wolf's answer. If doesn't return ok, follow steps of Annjawn's answer.

It solved for me in both cases.

If you use Heroku or otherwise have need to keep your application settings as environment variables, the figaro gem is very helpful.

Actually you don't even need the block:

  Dir.chdir 'C:/Users/name/Music'
  music = Dir['C:/Users/name/Music/*.{mp3, MP3}']
  puts 'what would you like to call the playlist?'
  playlist_name = gets.chomp + '.m3u'

  File.open(playlist_name, 'w').puts(music)

You can use this awesome library to compress. Add dependency in app-level gradel:

    dependencies {
    implementation 'id.zelory:compressor:3.0.0'
}

And then just compress the actual image file like this:

val compressedImageFile = Compressor.compress(context, actualImageFile)

In case you want to polyfill HashCode from netstandard2.1

public static class HashCode
{
    public static int Combine(params object[] instances)
    {
        int hash = 17;

        foreach (var i in instances)
        {
            hash = unchecked((hash * 31) + (i?.GetHashCode() ?? 0));
        }

        return hash;
    }
}

Note: If used with struct, it will allocate memory due to boxing

You can do this

cat /dev/urandom|od -N2 -An -i|awk -v f=2000 -v r=65000 '{printf "%i\n", f + r * $1 / 65536}'

Programmers may have questions about stack frames not in a broad term (that it is a singe entity in the stack that serves just one function call and keeps return address, arguments and local variables) but in a narrow sense – when the term stack frames is mentioned in context of compiler options.

Whether the author of the question has meant it or not, but the concept of a stack frame from the aspect of compiler options is a very important issue, not covered by the other replies here.

For example, Microsoft Visual Studio 2015 C/C++ compiler has the following option related to stack frames:

• /Oy (Frame-Pointer Omission)

GCC have the following:

• -fomit-frame-pointer (Don't keep the frame pointer in a register for functions that don't need one. This avoids the instructions to save, set up and restore frame pointers; it also makes an extra register available in many functions)

Intel C++ Compiler have the following:

• -fomit-frame-pointer (Determines whether EBP is used as a general-purpose register in optimizations)

which has the following alias:

• /Oy

Delphi has the following command-line option:

• -$W+ (Generate Stack Frames)

In that specific sense, from the compiler’s perspective, a stack frame is just the entry and exit code for the routine, that pushes an anchor to the stack – that can also be used for debugging and for exception handling. Debugging tools may scan the stack data and use these anchors for backtracing, while locating call sites in the stack, i.e. to display names of the functions in the order they have been called hierarchically. For Intel architecture, it is push ebp; mov ebp, esp or enter for entry and mov esp, ebp; pop ebp or leave for exit.

That’s why it is very important to understand for a programmer what a stack frame is in when it comes to compiler options – because the compiler can control whether to generate this code or not.

In some cases, the stack frame (entry and exit code for the routine) can be omitted by the compiler, and the variables will directly be accessed via the stack pointer (SP/ESP/RSP) rather than the convenient base pointer (BP/ESP/RSP). Conditions for omission of the stack frame, for example:

• the function is a leaf function (i.e. an end-entity that doesn’t call other functions);
• there are no try/finally or try/except or similar constructs, i.e. no exceptions are used;
• no routines are called with outgoing parameters on the stack;
• the function has no parameters;
• the function has no inline assembly code;
• etc...

Omitting stack frames (entry and exit code for the routine) can make code smaller and faster, but it may also negatively affect the debuggers’ ability to backtrace the data in the stack and to display it to the programmer. These are the compiler options that determine under which conditions a function should have the entry and exit code, for example: (a) always, (b) never, (c) when needed (specifying the conditions).

In order to change the label size you can select an appropriate size policy for the label like expanding or minimum expanding.

You can scale the pixmap by keeping its aspect ratio every time it changes:

QPixmap p; // load pixmap
// get label dimensions
int w = label->width();
int h = label->height();

// set a scaled pixmap to a w x h window keeping its aspect ratio 
label->setPixmap(p.scaled(w,h,Qt::KeepAspectRatio));

There are two places where you should add this code:

• When the pixmap is updated
• In the resizeEvent of the widget that contains the label

You may try this:

foreach(var item in yourArray)
{
    Console.WriteLine(item.ToString());
}

Also you may want to try something like this:

yourArray.ToList().ForEach(i => Console.WriteLine(i.ToString()));

EDIT: to get output in one line [based on your comment]:

 Console.WriteLine("[{0}]", string.Join(", ", yourArray));
 //output style:  [8, 1, 8, 8, 4, 8, 6, 8, 8, 8]

EDIT(2019): As it is mentioned in other answers it is better to use Array.ForEach<T> method and there is no need to do the ToList step.

Array.ForEach(yourArray, Console.WriteLine);

\a is the bell/alert character, which on some systems triggers a sound. \nnn, represents an arbitrary ASCII character in octal base. However, \0 is special in that it represents the null character no matter what.

To answer your original question, you could escape your '0' characters as well, as:

std::string ("\060\000\060", 3);

(since an ASCII '0' is 60 in octal)

Run the commented out section once, populate the _TruncateList table with the tables you want truncated, then run the rest of the script. The _ScriptLog table will need to be cleaned up over time if you do this a lot.

You can modify this if you want to do all tables, just put in SELECT name INTO #TruncateList FROM sys.tables. However, you usually don't want to do them all.

Also, this will affect all foreign keys in the database, and you can modify that as well if it's too blunt-force for your application. It's not for my purposes.

Real time includes the waiting time also (the waiting time for I/O etc.)

With C++17 you can use std::filesystem::is_directory function (https://en.cppreference.com/w/cpp/filesystem/is_directory). It accepts a std::filesystem::path object which can be constructed with a unicode path.

I am using Entity Framework to repupulate my database, and the users gets overridden each time I generate my database.

Now I run this each time I load a new DBContext:

cnt.Database.ExecuteSqlCommand("EXEC sp_addrolemember 'db_owner', 'NT AUTHORITY\\NETWORK SERVICE'");

MAC users - this issue was winding me up, as its not possible to open two different Visual Studio instances at the same time. Ive found a solution that works fine, though its a little unorthodox : get the latest beta testing version, which will install alongside your normal VS install in a separate sandbox (it does this automatically). You can then run both versions side by side, which is enough for what I needed - to be able to examine one project for structure, code etc., while doing the actual coding I need to do in the 'current' VS install instance.

There is nothing to change. Pass only in the connect function {useNewUrlParser: true }.

This will work:

    MongoClient.connect(url, {useNewUrlParser:true,useUnifiedTopology: true }, function(err, db) {
        if(err) {
            console.log(err);
        }
        else {
            console.log('connected to ' + url);
            db.close();
        }
    })

here allows is class of checkboxes on pages and var allows collects them in an array and you can check for checked true in for loop then perform the desired operation individually. Here I have set custom validity. I think it will solve your problem.

  $(".allows").click(function(){
   var allows = document.getElementsByClassName('allows');
   var chkd   = 0;  
   for(var i=0;i<allows.length;i++)
   {
       if(allows[i].checked===true)
       {
           chkd = 1;
       }else
       {

       }
   }

   if(chkd===0)
   {
       $(".allows").prop("required",true);
       for(var i=0;i<allows.length;i++)
        {
        allows[i].setCustomValidity("Please select atleast one option");
        }

   }else
   {
       $(".allows").prop("required",false);
       for(var i=0;i<allows.length;i++)
        {
        allows[i].setCustomValidity("");
        }
   }

}); 

For a time difference, note that the calendar starts at 01.01.1970, 01:00, not at 00:00. If you're using java.util.Date and java.text.SimpleDateFormat, you will have to compensate for 1 hour:

long start = System.currentTimeMillis();
long end = start + (1*3600 + 23*60 + 45) * 1000 + 678; // 1 h 23 min 45.678 s
Date timeDiff = new Date(end - start - 3600000); // compensate for 1h in millis
SimpleDateFormat timeFormat = new SimpleDateFormat("H:mm:ss.SSS");
System.out.println("Duration: " + timeFormat.format(timeDiff));

This will print:

Duration: 1:23:45.678

You have to use val() instead of value() and you have missed starting quote id=dbType" should be id="dbType"

Live Demo

Change

selection = $('this').value();

To

selection = $(this).val();

or

selection = this.value;

@ECHO OFF
SETLOCAL
SET "string=string1 by string2.txt"
SET "string=%string:* by =%"
ECHO +%string%+

GOTO :EOF

The above SET command will remove the unwanted data. Result shown between + to demonstrate absence of spaces.

Formula: set var=%somevar:*string1=string2%

will assign to var the value of somevar with all characters up to string1 replaced by string2. The enclosing quotes in a set command ensure that any stray trailing spaces on the line are not included in the value assigned.

You can 'goto case label' http://www.blackwasp.co.uk/CSharpGoto.aspx

The goto statement is a simple command that unconditionally transfers the control of the program to another statement. The command is often criticised with some developers advocating its removal from all high-level programming languages because it can lead to spaghetti code. This occurs when there are so many goto statements or similar jump statements that the code becomes difficult to read and maintain. However, there are programmers who point out that the goto statement, when used carefully, provides an elegant solution to some problems...

#!/bin/bash

set -e

_onexit() {
    [[ $TMPD ]] && rm -rf "$TMPD"
}

TMPD="$(mktemp -d)"
trap _onexit EXIT

_time_2() {
    "$@" 2>&3
}

_time_1() {
    time _time_2 "$@"
}

_time() {
    declare time_label="$1"
    shift
    exec 3>&2
    _time_1 "$@" 2>"$TMPD/timing.$time_label"
    echo "time[$time_label]"
    cat "$TMPD/timing.$time_label"
}

_time a _do_something
_time b _do_another_thing
_time c _finish_up

This has the benefit of not spawning sub shells, and the final pipeline has it's stderr restored to the real stderr.

Yes, C# supports that. There are several syntaxes available.

• Anonymous methods were added in C# 2.0:

  Func<int, int, int> add = delegate(int x, int y)
  {
      return x + y;
  };
  Action<int> print = delegate(int x)
  {
      Console.WriteLine(x);
  }
  Action<int> helloWorld = delegate // parameters can be elided if ignored
  {
      Console.WriteLine("Hello world!");
  }
  

• Lambdas are new in C# 3.0 and come in two flavours.

  • Expression lambdas:

    Func<int, int, int> add = (int x, int y) => x + y; // or...
    Func<int, int, int> add = (x, y) => x + y; // types are inferred by the compiler
    

  • Statement lambdas:

    Action<int> print = (int x) => { Console.WriteLine(x); };
    Action<int> print = x => { Console.WriteLine(x); }; // inferred types
    Func<int, int, int> add = (x, y) => { return x + y; };
    

• Local functions have been introduced with C# 7.0:

  int add(int x, int y) => x + y;
  void print(int x) { Console.WriteLine(x); }
  

There are basically two different types for these: Func and Action. Funcs return values but Actions don't. The last type parameter of a Func is the return type; all the others are the parameter types.

There are similar types with different names, but the syntax for declaring them inline is the same. An example of this is Comparison<T>, which is roughly equivalent to Func<T, T, int>.

Func<string, string, int> compare1 = (l,r) => 1;
Comparison<string> compare2 = (l, r) => 1;
Comparison<string> compare3 = compare1; // this one only works from C# 4.0 onwards

These can be invoked directly as if they were regular methods:

int x = add(23, 17); // x == 40
print(x); // outputs 40
helloWorld(x); // helloWorld has one int parameter declared: Action<int>
               // even though it does not make any use of it.

I make this small function, hope it helps. Here you can find the latest version browserDetection

function detectBrowser(userAgent){
  var chrome  = /.*(Chrome\/).*(Safari\/).*/g;
  var firefox = /.*(Firefox\/).*/g;
  var safari  = /.*(Version\/).*(Safari\/).*/g;
  var opera   = /.*(Chrome\/).*(Safari\/).*(OPR\/).*/g

  if(opera.exec(userAgent))
    return "Opera"
  if(chrome.exec(userAgent))
    return "Chrome"
  if(safari.exec(userAgent))
    return "Safari"
  if(firefox.exec(userAgent))
    return "Firefox"
}

SQL supports qualifying a column by prefixing the reference with either the full table name:

SELECT tbl_names.id, tbl_section.id, name, section
  FROM tbl_names
  JOIN tbl_section ON tbl_section.id = tbl_names.id 

...or a table alias:

SELECT n.id, s.id, n.name, s.section
  FROM tbl_names n
  JOIN tbl_section s ON s.id = n.id 

The table alias is the recommended approach -- why type more than you have to?

Why Do These Queries Look Different?

Secondly, my answers use ANSI-92 JOIN syntax (yours is ANSI-89). While they perform the same, ANSI-89 syntax does not support OUTER joins (RIGHT, LEFT, FULL). ANSI-89 syntax should be considered deprecated, there are many on SO who will not vote for ANSI-89 syntax to reinforce that. For more information, see this question.

How about

with open(csv_input_path + file, 'r') as ft:
    header = ft.readline() # read only first line; returns string
    header_list = header.split(',') # returns list

I am assuming your input file is CSV format. If using pandas, it takes more time if the file is big size because it loads the entire data as the dataset.

I got this to work:

explicit conversion

    public override object ReadJson(JsonReader reader, Type objectType, object existingValue,
                                    JsonSerializer serializer)
    {
        var jsonObj = serializer.Deserialize<List<SomeObject>>(reader);
        var conversion = jsonObj.ConvertAll((x) => x as ISomeObject);

        return conversion;
    }

adding following to application.rb works

 config.time_zone = 'Eastern Time (US & Canada)'
 config.active_record.default_timezone = :local # Or :utc

If you want distinct values from only two fields, plus return other fields with them, then the other fields must have some kind of aggregation on them (sum, min, max, etc.), and the two columns you want distinct must appear in the group by clause. Otherwise, it's just as Decker says.

For anyone finding this solution in 2015 and moving forward...

The mysql_real_escape_string() function is deprecated as of PHP 5.5.0.

See: php.net

Warning

This extension is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:

mysqli_real_escape_string()

PDO::quote()

I have had a lot of difficulty with this as I have a custom spinner, if I setBackground then the Drawable would stretch. My solution to this was to add a drawable to the right of the Spinner TextView. Heres a code snippet from my Custom Spinner. The trick is to Override getView and customize the Textview as you wish.

public class NoTextSpinnerArrayAdapter extends ArrayAdapter<String> {

    private String text = "0";

    public NoTextSpinnerArrayAdapter(Context context, int textViewResourceId, List<String> objects) {
        super(context, textViewResourceId, objects);
    }

    public void updateText(String text){
        this.text = text;
        notifyDataSetChanged();
    }

    public String getText(){
        return text;
    }

    @NonNull
    public View getView(int position, View convertView, @NonNull ViewGroup parent) {
        View view = super.getView(position, convertView, parent);
        TextView textView = view.findViewById(android.R.id.text1);
        textView.setCompoundDrawablePadding(16);
        textView.setCompoundDrawablesWithIntrinsicBounds(0, 0, R.drawable.ic_menu_white_24dp, 0);

        textView.setGravity(Gravity.END);
        textView.setText(text);
        return view;
    }
}

You also need to set the Spinner background to transparent:

<lifeunlocked.valueinvestingcheatsheet.views.SelectAgainSpinner
            android:id="@+id/saved_tickers_spinner"
            android:background="@android:color/transparent"
            android:layout_width="60dp"
            android:layout_height="match_parent"
            tools:layout_editor_absoluteX="248dp"
            tools:layout_editor_absoluteY="16dp" />

and my custom spinner if you want it....

public class SelectAgainSpinner extends android.support.v7.widget.AppCompatSpinner {
    public SelectAgainSpinner(Context context) {
        super(context);
    }

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

    public SelectAgainSpinner(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public void setPopupBackgroundDrawable(Drawable background) {
        super.setPopupBackgroundDrawable(background);
    }

    @Override
    public void setSelection(int position, boolean animate) {
        boolean sameSelected = position == getSelectedItemPosition();
        super.setSelection(position, animate);
        if (sameSelected) {
            // Spinner does not call the OnItemSelectedListener if the same item is selected, so do it manually now
            if (getOnItemSelectedListener() != null) {
                getOnItemSelectedListener().onItemSelected(this, getSelectedView(), position, getSelectedItemId());
            }
        }
    }

    @Override
    public void setSelection(int position) {
        boolean sameSelected = position == getSelectedItemPosition();
        super.setSelection(position);
        if (sameSelected) {
            // Spinner does not call the OnItemSelectedListener if the same item is selected, so do it manually now
            if (getOnItemSelectedListener() != null) {
                getOnItemSelectedListener().onItemSelected(this, getSelectedView(), position, getSelectedItemId());
            }
        }
    }
}

You may be looking for an automated tool that will automatically generate a lot of stuff for you. But here's a free, generally powerful diagramming tool useful not only for UML but for all kinds of diagramming tasks. It accepts as input and outputs to a wide variety of commonly used file formats. It's called yEd, and it's worth a look

Try this:

$comments_collection = $post->comments()->get()->toArray();

see this can help you
toArray() method in Collections

Since it's an array before you cast it, casting it makes no sense.

You may want a recursive cast, which would look something like this:

function arrayCastRecursive($array)
{
    if (is_array($array)) {
        foreach ($array as $key => $value) {
            if (is_array($value)) {
                $array[$key] = arrayCastRecursive($value);
            }
            if ($value instanceof stdClass) {
                $array[$key] = arrayCastRecursive((array)$value);
            }
        }
    }
    if ($array instanceof stdClass) {
        return arrayCastRecursive((array)$array);
    }
    return $array;
}

Usage:

$obj = new stdClass;
$obj->aaa = 'asdf';
$obj->bbb = 'adsf43';
$arr = array('asdf', array($obj, 3));

var_dump($arr);
$arr = arrayCastRecursive($arr);
var_dump($arr);

Result before:

array
    0 => string 'asdf' (length = 4)
  1 => 
    array
        0 =>
        object(stdClass)[1]
          public 'aaa' => string 'asdf' (length = 4)
          public 'bbb' => string 'adsf43' (length = 6)
      1 => int 3

Result after:

array
    0 => string 'asdf' (length = 4)
  1 => 
    array
        0 =>
        array
          'aaa' => string 'asdf' (length = 4)
          'bbb' => string 'adsf43' (length = 6)
      1 => int 3

Note:

Tested and working with complex arrays where a stdClass object can contain other stdClass objects.

Some great worksheet-fu in the other answers but I think they've overlooked that you can define a user-defined function (udf) and call this from the sheet or a formula.

The next problem you have is to decide either to work with a whole array or with element.

For example this UDF function code

Public Function UdfSplit(ByVal sText As String, Optional ByVal sDelimiter As String = " ", Optional ByVal lIndex As Long = -1) As Variant
    Dim vSplit As Variant
    vSplit = VBA.Split(sText, sDelimiter)
    If lIndex > -1 Then
        UdfSplit = vSplit(lIndex)
    Else
        UdfSplit = vSplit
    End If
End Function

allows single elements with the following in one cell

=UdfSplit("EUR/USD","/",0)

or one can use a blocks of cells with

=UdfSplit("EUR/USD","/")

here's an answer that does follow the syntax of

$(element).hasAnyOfClasses("class1","class2","class3")

(function($){
    $.fn.hasAnyOfClasses = function(){
        for(var i= 0, il=arguments.length; i<il; i++){
            if($self.hasClass(arguments[i])) return true;
        }
        return false;
    }
})(jQuery);

it's not the fastest, but its unambiguous and the solution i prefer. bench: http://jsperf.com/hasclasstest/10

Calendar start = Calendar.getInstance();
Calendar end = Calendar.getInstance();
start.set(2010, 7, 23);
end.set(2010, 8, 26);
Date startDate = start.getTime();
Date endDate = end.getTime();
long startTime = startDate.getTime();
long endTime = endDate.getTime();
long diffTime = endTime - startTime;
long diffDays = diffTime / (1000 * 60 * 60 * 24);
DateFormat dateFormat = DateFormat.getDateInstance();
System.out.println("The difference between "+
  dateFormat.format(startDate)+" and "+
  dateFormat.format(endDate)+" is "+
  diffDays+" days.");

This will not work when crossing daylight savings time (or leap seconds) as orange80 pointed out and might as well not give the expected results when using different times of day. Using JodaTime might be easier for correct results, as the only correct way with plain Java before 8 I know is to use Calendar's add and before/after methods to check and adjust the calculation:

start.add(Calendar.DAY_OF_MONTH, (int)diffDays);
while (start.before(end)) {
    start.add(Calendar.DAY_OF_MONTH, 1);
    diffDays++;
}
while (start.after(end)) {
    start.add(Calendar.DAY_OF_MONTH, -1);
    diffDays--;
}

This approach using git-remote worked well for me for HTTPS remotes:

$ git remote -v | grep "(fetch)" | sed 's/.*\/\([^ ]*\)\/.*/\1/'
                                                |  |        | |
                                                |  |        | +---------------+
                                                |  |        | Extract capture |
                                                |  +--------------------+-----+
                                                |Repository name capture|
                                                +-----------------------+

Example

You have three possibilities to do this, but it's not trivial. The main idea of all IDEs is that all of them are the parents of the child (debug) processes. In this case, it is possible to manipulate with standard input, output and error handler. So IDEs start child applications and redirect out into the internal output window. I know about one more possibility, but it will come in future

1. You could implement your own debug engine for Visual Studio. Debug Engine control starting and debugging for application. Examples for this you could find how to do this on docs.microsoft.com (Visual Studio Debug engine)
2. Redirect form application using duplication of std handler for c++ or use Console.SetOut(TextWriter) for c#. If you need to print into the output window you need to use Visual Studio extension SDK. Example of the second variant you could find on Github.
3. Start application that uses System.Diagnostics.Debug.WriteLine (for printing into output) and than it will start child application. On starting a child, you need to redirect stdout into parent with pipes. You could find an example on MSDN. But I think this is not the best way.

Give an ID to uniquely identify the button, lets say myBtn

// when DOM is ready
$(document).ready(function () {

     // Attach Button click event listener 
    $("#myBtn").click(function(){

         // show Modal
         $('#myModal').modal('show');
    });
});

JSFIDDLE

The safest way to do this is to prompt for the password beforehand and then pipe it into the command. Prompting for the password will avoid having the password saved anywhere in your code and it also won't show up in your bash history. Here's an example:

from getpass import getpass
from subprocess import Popen, PIPE

password = getpass("Please enter your password: ")
# sudo requires the flag '-S' in order to take input from stdin
proc = Popen("sudo -S apach2ctl restart".split(), stdin=PIPE, stdout=PIPE, stderr=PIPE)
# Popen only accepts byte-arrays so you must encode the string
proc.communicate(password.encode())

CSS:

.imgMaxWidth {
    max-width:100px;
    height:auto;
}
.imgMaxHeight {
    max-height:100px;
    width:auto;
}

HTML:

<img src="image.jpg" class="imageToResize imgMaxHeight" />

jQuery:

<script type="text/javascript">
function onLoadF() {
    $('.imageToResize').each(function() {
        var imgWidth = $(this).width();
        if (imgWidth>100) {
            $(this).removeClass("imgMaxHeight").addClass("imgMaxWidth");
        }
    });
}
window.onload = onLoadF;
</script>

In terms of coding, a bidirectional relationship is more complex to implement because the application is responsible for keeping both sides in synch according to JPA specification 5 (on page 42). Unfortunately the example given in the specification does not give more details, so it does not give an idea of the level of complexity.

When not using a second level cache it is usually not a problem to do not have the relationship methods correctly implemented because the instances get discarded at the end of the transaction.

When using second level cache, if anything gets corrupted because of wrongly implemented relationship handling methods, this means that other transactions will also see the corrupted elements (the second level cache is global).

A correctly implemented bi-directional relationship can make queries and the code simpler, but should not be used if it does not really make sense in terms of business logic.

Dot notation and the properties are equivalent. So you would accomplish like so:

var myObj = new Object;
var a = 'string1';
myObj[a] = 'whatever';
alert(myObj.string1)

(alerts "whatever")

Unfortunately, no. Not with HTML and CSS. You need an a element to make a link, and you can't wrap an entire table row in one.

The closest you can get is linking every table cell. Personally I'd just link one cell and use JavaScript to make the rest clickable. It's good to have at least one cell that really looks like a link, underlined and all, for clarity anyways.

Here's a simple jQuery snippet to make all table rows with links clickable (it looks for the first link and "clicks" it)

$("table").on("click", "tr", function(e) {
    if ($(e.target).is("a,input")) // anything else you don't want to trigger the click
        return;

    location.href = $(this).find("a").attr("href");
});

I don't know that what you want to do is possible. From my understanding, sending an email from a web form requires a server side language to communicate with a mail server and send messages.

Are you running PHP or ASP.NET?

Aah you just need to add a name parameter in the

RabbitMQ is a solid, general-purpose message broker that supports several protocols such as AMQP, MQTT, STOMP, etc. It can handle high throughput. A common use case for RabbitMQ is to handle background jobs or long-running task, such as file scanning, image scaling or PDF conversion. RabbitMQ is also used between microservices, where it serves as a means of communicating between applications, avoiding bottlenecks passing messages.

Kafka is a message bus optimized for high-throughput ingestion data streams and replay. Use Kafka when you have the need to move a large amount of data, process data in real-time or analyze data over a time period. In other words, where data need to be collected, stored, and handled. An example is when you want to track user activity on a webshop and generate suggested items to buy. Another example is data analysis for tracking, ingestion, logging or security.

Kafka can be seen as a durable message broker where applications can process and re-process streamed data on disk. Kafka has a very simple routing approach. RabbitMQ has better options if you need to route your messages in complex ways to your consumers. Use Kafka if you need to support batch consumers that could be offline or consumers that want messages at low latency. 

In order to understand how to read data from Kafka, we first need to understand its consumers and consumer groups. Partitions allow you to parallelize a topic by splitting the data across multiple nodes. Each record in a partition is assigned and identified by its unique offset. This offset points to the record in a partition. In the latest version of Kafka, Kafka maintains a numerical offset for each record in a partition. A consumer in Kafka can either automatically commit offsets periodically, or it can choose to control this committed position manually. RabbitMQ will keep all states about consumed/acknowledged/unacknowledged messages. I find Kafka more complex to understand than the case of RabbitMQ, where the message is simply removed from the queue once it's acked.

RabbitMQ's queues are fastest when they're empty, while Kafka retains large amounts of data with very little overhead - Kafka is designed for holding and distributing large volumes of messages. (If you plan to have very long queues in RabbitMQ you could have a look at lazy queues.)

Kafka is built from the ground up with horizontal scaling (scale by adding more machines) in mind, while RabbitMQ is mostly designed for vertical scaling (scale by adding more power).

RabbitMQ has a built-in user-friendly interface that lets you monitor and handle your RabbitMQ server from a web browser. Among other things, queues, connections, channels, exchanges, users and user permissions can be handled - created, deleted and listed in the browser and you can monitor message rates and send/receive messages manually. Kafka has a number of open-source tools, and also some commercial once, offering the administration and monitoring functionalities. I would say that it's easier/gets faster to get a good understanding of RabbitMQ.

In general, if you want a simple/traditional pub-sub message broker, the obvious choice is RabbitMQ, as it will most probably scale more than you will ever need it to scale. I would have chosen RabbitMQ if my requirements were simple enough to deal with system communication through channels/queues, and where retention and streaming is not a requirement.

There are two main situations where I would choose RabbitMQ; For long-running tasks, when I need to run reliable background jobs. And for communication and integration within, and between applications, i.e as middleman between microservices; where a system simply needs to notify another part of the system to start to work on a task, like ordering handling in a webshop (order placed, update order status, send order, payment, etc.).

In general, if you want a framework for storing, reading (re-reading), and analyzing streaming data, use Apache Kafka. It’s ideal for systems that are audited or those that need to store messages permanently. These can also be broken down into two main use cases for analyzing data (tracking, ingestion, logging, security etc.) or real-time processing.

More reading, use cases and some comparison data can be found here: https://www.cloudamqp.com/blog/2019-12-12-when-to-use-rabbitmq-or-apache-kafka.html

I do work at a company providing both Apache Kafka and RabbitMQ as a Service.

Underscore-java library contains methods push(values), pop(), shift() and unshift(values).

Code example:

import com.github.underscore.U:

List<String> strings = Arrays.asList("one", "two", " three");
List<String> newStrings = U.push(strings, "four", "five");
// ["one", " two", "three", " four", "five"]
String newPopString = U.pop(strings).fst();
// " three"
String newShiftString = U.shift(strings).fst();
// "one"
List<String> newUnshiftStrings = U.unshift(strings, "four", "five");
// ["four", " five", "one", " two", "three"]

My requirement was slightly different but used two data sources.

I have used two data sources for same JPA entities from same package. One for executing DDL at the server startup to create/update tables and another one is for DML at runtime.

The DDL connection should be closed after DDL statements are executed, to prevent further usage of super user previlleges anywhere in the code.

You should add the target="_blank" and rel="noopener noreferrer" in the anchor tag.

For example:

<a target="_blank" rel="noopener noreferrer" href="http://your_url_here.html">Link</a>

Adding rel="noopener noreferrer" is not mandatory, but it's a recommended security measure. More information can be found in the links below.

Source:

• MDN | HTML element <a> | attribute target
• About rel=noopener
• Opens External Anchors Using rel="noopener"

In terminal run this command in the folder where the systlesheets are:

sass --watch style.scss:style.css 

Source:

http://sass-lang.com/

When ever it notices a change in the .scss file it will update your .css

This only works when your .scss is on your local machine. Try copying the code to a file and running it locally.

Instructions

• Copy the python file to /bin:

  sudo cp -i /path/to/your_script.py /bin

• Add A New Cron Job:

  sudo crontab -e

  Scroll to the bottom and add the following line (after all the #'s):

  @reboot python /bin/your_script.py &

  The “&” at the end of the line means the command is run in the background and it won’t stop the system booting up.

• Test it:

  sudo reboot

Practical example:

• Add this file to your Desktop: test_code.py (run it to check that it works for you)

  from os.path import expanduser
  import datetime
  
  file = open(expanduser("~") + '/Desktop/HERE.txt', 'w')
  file.write("It worked!\n" + str(datetime.datetime.now()))
  file.close()
  

• Run the following commands:

  sudo cp -i ~/Desktop/test_code.py /bin

  sudo crontab -e

• Add the following line and save it:

  @reboot python /bin/test_code.py &

• Now reboot your computer and you should find a new file on your Desktop: HERE.txt

readlink -f filename 

gives the full absolute path. but if the file is a symlink, u'll get the final resolved name.

I had the same problem but solved it when I realized that I didn't compile it with the correct casing. You may have been doing

javac Weatherarray.java

when it should have been

javac WeatherArray.java

I believe this is what you want:

DataTable dtTable = new DataTable();
foreach (DataRow dtRow in dtTable.Rows)
{
    foreach (DataColumn dc in dtRow.ItemArray)
    {

    }
}

Personally, I wouldn't use the LIKE string comparison on the ID field or any other numeric field. It doesn't make sense for a search for ID# "216" to return 16216, 21651, 3216087, 5321668..., and so on and so forth; likewise with salary.

Also, if you want to use prepared statements to prevent SQL injections, you would use a query string like:

SELECT * FROM job WHERE `position` LIKE CONCAT('%', ? ,'%') OR ...

It is lot easier to understand an idea through example. What have been told about callback function in C so far are great answers, but probably the biggest benefit of using the feature is to keep the code clean and uncluttered.

Example

The following C code implements quick sorting. The most interesting line in the code below is this one, where we can see the callback function in action:

qsort(arr,N,sizeof(int),compare_s2b);

The compare_s2b is the name of function which qsort() is using to call the function. This keeps qsort() so uncluttered (hence easier to maintain). You just call a function by name from inside another function (of course, the function prototype declaration, at the least, must precde before it can be called from another function).

The Complete Code

#include <stdio.h>
#include <stdlib.h>

int arr[]={56,90,45,1234,12,3,7,18};
//function prototype declaration 

int compare_s2b(const void *a,const void *b);

int compare_b2s(const void *a,const void *b);

//arranges the array number from the smallest to the biggest
int compare_s2b(const void* a, const void* b)
{
    const int* p=(const int*)a;
    const int* q=(const int*)b;

    return *p-*q;
}

//arranges the array number from the biggest to the smallest
int compare_b2s(const void* a, const void* b)
{
    const int* p=(const int*)a;
    const int* q=(const int*)b;

    return *q-*p;
}

int main()
{
    printf("Before sorting\n\n");

    int N=sizeof(arr)/sizeof(int);

    for(int i=0;i<N;i++)
    {
        printf("%d\t",arr[i]);
    }

    printf("\n");

    qsort(arr,N,sizeof(int),compare_s2b);

    printf("\nSorted small to big\n\n");

    for(int j=0;j<N;j++)
    {
        printf("%d\t",arr[j]);
    }

    qsort(arr,N,sizeof(int),compare_b2s);

    printf("\nSorted big to small\n\n");

    for(int j=0;j<N;j++)
    {
        printf("%d\t",arr[j]);
    }

    exit(0);
}

import itertools
ab = itertools.chain(['it'], ['was'], ['annoying'])
list(ab)

Just another method....

You are allocating your string on the stack, and then returning a pointer to it. When your function returns, any stack allocations become invalid; the pointer now points to a region on the stack that is likely to be overwritten the next time a function is called.

In order to do what you're trying to do, you need to do one of the following:

1. Allocate memory on the heap using malloc or similar, then return that pointer. The caller will then need to call free when it is done with the memory.
2. Allocate the string on the stack in the calling function (the one that will be using the string), and pass a pointer in to the function to put the string into. During the entire call to the calling function, data on its stack is valid; its only once you return that stack allocated space becomes used by something else.

If you are targeting Windows XP (v140_xp), try installing Windows XP Support for C++.

Starting with Visual Studio 2012, the default toolset (v110) dropped support for Windows XP. As a result, a Windows.h error can occur if your project is targeting Windows XP with the default C++ packages.

Check which Windows SDK version is specified in your project's Platform Toolset. (Project ? Properties ? Configuration Properties ? General). If your Toolset ends in _xp, you'll need to install XP support.

Open the Visual Studio Installer and click Modify for your version of Visual Studio. Open the Individual Components tab and scroll down to Compilers, build tools, and runtimes. Near the bottom, check Windows XP support for C++ and click Modify to begin installing.

The hide class is useful to keep the content hidden on page load.

My solution to this is during initialization, switch to jquery's hide:

$('.targets').hide().removeClass('hide');

Then show() and hide() should function as normal.

The problem is that C++ is a statically-typed language, meaning that if something is declared as a string, it's a string, and if something is declared as a double, it's a double. Unlike other languages like JavaScript or PHP, there is no way to automatically convert from a string to a numeric value because the conversion might not be well-defined. For example, if you try converting the string "Hi there!" to a double, there's no meaningful conversion. Sure, you could just set the double to 0.0 or NaN, but this would almost certainly be masking the fact that there's a problem in the code.

To fix this, don't buffer the file contents into a string. Instead, just read directly into the double:

double lol;
openfile >> lol;

This reads the value directly as a real number, and if an error occurs will cause the stream's .fail() method to return true. For example:

double lol;
openfile >> lol;

if (openfile.fail()) {
    cout << "Couldn't read a double from the file." << endl;
}

Waterfall methodology is a sequential design process. This means that as each of the eight stages (conception, initiation, analysis, design, construction, testing, implementation, and maintenance) are completed, the developers move on to the next step.

As this process is sequential, once a step has been completed, developers can’t go back to a previous step – not without scratching the whole project and starting from the beginning. There’s no room for change or error, so a project outcome and an extensive plan must be set in the beginning and then followed careful

ACP Agile Certification came about as a “solution” to the disadvantages of the waterfall methodology. Instead of a sequential design process, the Agile methodology follows an incremental approach. Developers start off with a simplistic project design, and then begin to work on small modules. The work on these modules is done in weekly or monthly sprints, and at the end of each sprint, project priorities are evaluated and tests are run. These sprints allow for bugs to be discovered, and customer feedback to be incorporated into the design before the next sprint is run.

The process, with its lack of initial design and steps, is often criticized for its collaborative nature that focuses on principles rather than process.

I'm maybe a little bit late but I'm currently trying to develop a program which can brute force a password protected zip archive. First I tried all commands I found in the internet to extract it through cmd... But it never worked....Every time I tried it, the cmd output said, that the key was wrong but it was right. I think they just disenabled this function in a current version.

What I've done to Solve the problem was to download an older 7zip version(4.?) and to use this for extracting through cmd.

This is the command: "C:/Program Files (86)/old7-zip/7z.exe" x -pKey "C:/YOURE_ZIP_PATH"

The first value("C:/Program Files (86)/old7-zip/7z.exe") has to be the path where you have installed the old 7zip to. The x is for extract and the -p For you're password. Make sure you put your password without any spaces behind the -p! The last value is your zip archive to extract. The destination where the zip is extracted to will be the current path of cmd. You can change it with: cd YOURE_PATH

Now I let execute this command through java with my password trys. Then I check the error output stream of cmd and if it is null-> then the password is right!

you could connect all the data you need from the file to a single string, and in the excel sheet seperate it with text to column. here is an example i did for same issue, enjoy:

Sub CP()
Dim ToolFile As String

Cells(3, 2).Select

For i = 0 To 5
    r = ActiveCell.Row
    ToolFile = Cells(r, 7).Value
    On Error Resume Next
    ActiveCell.Value = CP_getdatta(ToolFile)

    'seperate data by "-"
    Selection.TextToColumns Destination:=Range("C3"), DataType:=xlDelimited, _
        TextQualifier:=xlDoubleQuote, ConsecutiveDelimiter:=False, Tab:=True, _
        Semicolon:=False, Comma:=False, Space:=False, Other:=True, OtherChar _
        :="-", FieldInfo:=Array(Array(1, 1), Array(2, 1)), TrailingMinusNumbers:=True

Cells(r + 1, 2).Select
Next


End Sub

Function CP_getdatta(ToolFile As String) As String
    Workbooks.Open Filename:=ToolFile, UpdateLinks:=False, ReadOnly:=True

    Range("A56000").Select
    Selection.End(xlUp).Select
    x = CStr(ActiveCell.Value)
    ActiveCell.Offset(0, 20).Select
    Selection.End(xlToLeft).Select
    While IsNumeric(ActiveCell.Value) = False
        ActiveCell.Offset(0, -1).Select
    Wend
    ' combine data to 1 string
    CP_getdatta = CStr(x & "-" & ActiveCell.Value)
    ActiveWindow.Close False

End Function

The question is already answered but I think I've found the solution that is simpler and more relevant to the question title, here it is:

var cli = new WebClient();
cli.Headers[HttpRequestHeader.ContentType] = "application/json";
string response = cli.UploadString("http://some/address", "{some:\"json data\"}");

PS: In the most of .net implementations, but not in all WebClient is IDisposable, so of cource it is better to do 'using' or 'Dispose' on it. However in this particular case it is not really necessary.

This is more predictable then "line-height"

Pythont 3.5 added the methods run() and call() to the subprocess module, both returning a CompletedProcess object. With this you are fine using proc.stdout.splitlines():

proc = subprocess.run( comman, shell=True, capture_output=True, text=True, check=True )
for line in proc.stdout.splitlines():
   print "stdout:", line

$this->db->where('accommodation BETWEEN '' . $sdate . '' AND '' . $edate . ''');

this is my solution

You could try adding an<hr>and styling that. Its a minimal markup change but seems to need less css so that might do the trick.

fiddle:

http://jsfiddle.net/BhxsZ/

just note, The different between the methods are, if the header is not exist

request.headers.get('your-header-name')

will return None or no exception, so you can use it like

if request.headers.get('your-header-name'):
    ....

but the following will throw an error

if request.headers['your-header-name'] # KeyError: 'your-header-name'
    ....

You can handle it by

if 'your-header-name' in request.headers:
   customHeader = request.headers['your-header-name']
   ....

Have the element display as a block:

display: block;

I use @Thiho answer but i get this error:

'git' is not recognized as an internal or external command

For solving that i use this steps:

I add the following paths to PATH:

• C:\Program Files\Git\bin\

• C:\Program Files\Git\cmd\

In windows 7:

1. Right-click "Computer" on the Desktop or Start Menu.
2. Select "Properties".
3. On the very far left, click the "Advanced system settings" link.
4. Click the "Environment Variables" button at the bottom.
5. Double-click the "Path" entry under "System variables".
6. At the end of "Variable value", insert a ; if there is not already one, and then C:\Program Files\Git\bin\;C:\Program Files\Git\cmd. Do not put a space between ; and the entry.

Finally close and re-open your console.

You can test if your array has an upper case or lower case string by using the match method and regex, below is just a basic foundation to start your test

  var array = ['a', 'b', 'c', 'A', 'B', 'C', '(', ')', '+', '-', '~', '*'];
  var character = array.join('')
      console.log(character)

  var test = function(search){
      upperCase = search.match(/[A-Z]/g)
      console.log(upperCase)

      lowerCase = search.match(/[a-z]/g)
      console.log(lowerCase)
   }

   test(character)

The delete command has no effect on regular variables, only properties. After the delete command the property doesn't have the value null, it doesn't exist at all.

If the property is an object reference, the delete command deletes the property but not the object. The garbage collector will take care of the object if it has no other references to it.

Example:

var x = new Object();
x.y = 42;

alert(x.y); // shows '42'

delete x; // no effect
alert(x.y); // still shows '42'

delete x.y; // deletes the property
alert(x.y); // shows 'undefined'

(Tested in Firefox.)

Languages like scala&python give to you very powerful stuff like patternMatching, unfortunately this is still a missing-feature in Java...

but there is a solution (which I don't like in most of the cases), you can do something like this:

final int s1Value = 0;
final int s2Value = 0;
final String s1 = "a";
final String s2 = "g";

switch (s1 + s2 + s1Value + s2Value){
    case "ag00": return true;
    default: return false;
}

You can add remotes with:

git remote add a urla
git remote add b urlb

Then to update all the repos do:

git remote update

As King King said, you must add the browser specific prefix. This should cover most browsers:

I don't like adding new package into my project just to handle this simple task.

And also, I try my best to avoid RECURSIVE algorithm.... since, for most cases it is slower compared to non Recursive one.

So I made a function to get all the folder content (and its sub folder).... NON-Recursively

var getDirectoryContent = function(dirPath) {
    /* 
        get list of files and directories from given dirPath and all it's sub directories
        NON RECURSIVE ALGORITHM
        By. Dreamsavior
    */
    var RESULT = {'files':[], 'dirs':[]};

    var fs = fs||require('fs');
    if (Boolean(dirPath) == false) {
        return RESULT;
    }
    if (fs.existsSync(dirPath) == false) {
        console.warn("Path does not exist : ", dirPath);
        return RESULT;
    }

    var directoryList = []
    var DIRECTORY_SEPARATOR = "\\";
    if (dirPath[dirPath.length -1] !== DIRECTORY_SEPARATOR) dirPath = dirPath+DIRECTORY_SEPARATOR;

    directoryList.push(dirPath); // initial

    while (directoryList.length > 0) {
        var thisDir  = directoryList.shift(); 
        if (Boolean(fs.existsSync(thisDir) && fs.lstatSync(thisDir).isDirectory()) == false) continue;

        var thisDirContent = fs.readdirSync(thisDir);
        while (thisDirContent.length > 0) { 
            var thisFile  = thisDirContent.shift(); 
            var objPath = thisDir+thisFile

            if (fs.existsSync(objPath) == false) continue;
            if (fs.lstatSync(objPath).isDirectory()) { // is a directory
                let thisDirPath = objPath+DIRECTORY_SEPARATOR; 
                directoryList.push(thisDirPath);
                RESULT['dirs'].push(thisDirPath);

            } else  { // is a file
                RESULT['files'].push(objPath); 

            } 
        } 

    }
    return RESULT;
}

the only drawback of this function is that this is Synchronous function... You have been warned ;)

No, cp can copy multiple sources but will only copy to a single destination. You need to arrange to invoke cp multiple times - once per destination - for what you want to do; using, as you say, a loop or some other tool.

dataframe[:n] - Will return first n-1 rows

The RelativeLayout (i.e. the ViewParent) should have a resource Id defined in the layout file (for example, android:id=@+id/myParentViewId). If you don't do that, the call to getId will return null. Look at this answer for more info.

Casting in Java isn't magic, it's you telling the compiler that an Object of type A is actually of more specific type B, and thus gaining access to all the methods on B that you wouldn't have had otherwise. You're not performing any kind of magic or conversion when performing casting, you're essentially telling the compiler "trust me, I know what I'm doing and I can guarantee you that this Object at this line is actually an <Insert cast type here>." For example:

Object o = "str";
String str = (String)o;

The above is fine, not magic and all well. The object being stored in o is actually a string, and therefore we can cast to a string without any problems.

There's two ways this could go wrong. Firstly, if you're casting between two types in completely different inheritance hierarchies then the compiler will know you're being silly and stop you:

String o = "str";
Integer str = (Integer)o; //Compilation fails here

Secondly, if they're in the same hierarchy but still an invalid cast then a ClassCastException will be thrown at runtime:

Number o = new Integer(5);
Double n = (Double)o; //ClassCastException thrown here

This essentially means that you've violated the compiler's trust. You've told it you can guarantee the object is of a particular type, and it's not.

Why do you need casting? Well, to start with you only need it when going from a more general type to a more specific type. For instance, Integer inherits from Number, so if you want to store an Integer as a Number then that's ok (since all Integers are Numbers.) However, if you want to go the other way round you need a cast - not all Numbers are Integers (as well as Integer we have Double, Float, Byte, Long, etc.) And even if there's just one subclass in your project or the JDK, someone could easily create another and distribute that, so you've no guarantee even if you think it's a single, obvious choice!

Regarding use for casting, you still see the need for it in some libraries. Pre Java-5 it was used heavily in collections and various other classes, since all collections worked on adding objects and then casting the result that you got back out the collection. However, with the advent of generics much of the use for casting has gone away - it has been replaced by generics which provide a much safer alternative, without the potential for ClassCastExceptions (in fact if you use generics cleanly and it compiles with no warnings, you have a guarantee that you'll never get a ClassCastException.)

Use:

SELECT *
  FROM YOUR_TABLE
 WHERE creation_date <= TRUNC(SYSDATE) - 30

SYSDATE returns the date & time; TRUNC resets the date to being as of midnight so you can omit it if you want the creation_date that is 30 days previous including the current time.

Depending on your needs, you could also look at using ADD_MONTHS:

SELECT *
  FROM YOUR_TABLE
 WHERE creation_date <= ADD_MONTHS(TRUNC(SYSDATE), -1)

If you check the Integer class you will find that valueof call parseInt method. The big difference is caching when you call valueof API . It cache if the value is between -128 to 127 Please find below the link for more information

If pip doesn't come with your installation of python 3.6, this may work:

wget https://bootstrap.pypa.io/get-pip.py
sudo python3.6 get-pip.py

then you can python -m install

if using /bin/sh you can use:

if [ <condition> ] && [ <condition> ]; then
    ...
fi

if using /bin/bash you can use:

if [[ <condition> && <condition> ]]; then
    ...
fi

Explicit cursors are rarely needed in plpgsql. Use the simpler and faster implicit cursor of a FOR loop:

Note: Since table names are not unique per database, you have to schema-qualify table names to be sure. Also, I limit the function to the default schema 'public'. Adapt to your needs, but be sure to exclude the system schemas pg_* and information_schema.

Be very careful with these functions. They nuke your database. I added a child safety device. Comment the RAISE NOTICE line and uncomment EXECUTE to prime the bomb ...

CREATE OR REPLACE FUNCTION f_truncate_tables(_username text)
  RETURNS void AS
$func$
DECLARE
   _tbl text;
   _sch text;
BEGIN
   FOR _sch, _tbl IN 
      SELECT schemaname, tablename
      FROM   pg_tables
      WHERE  tableowner = _username
      AND  
      -- dangerous, test before you execute!
      RAISE NOTICE '%',  -- once confident, comment this line ...
      -- EXECUTE         -- ... and uncomment this one
         format('TRUNCATE TABLE %I.%I CASCADE', _sch, _tbl);
   END LOOP;
END
$func$ LANGUAGE plpgsql;

format() requires Postgres 9.1 or later. In older versions concatenate the query string like this:

'TRUNCATE TABLE ' || quote_ident(_sch) || '.' || quote_ident(_tbl)  || ' CASCADE';

Single command, no loop

Since we can TRUNCATE multiple tables at once we don't need any cursor or loop at all:

• Passing table names in an array

Aggregate all table names and execute a single statement. Simpler, faster:

CREATE OR REPLACE FUNCTION f_truncate_tables(_username text)
  RETURNS void AS
$func$
BEGIN
   -- dangerous, test before you execute!
   RAISE NOTICE '%',  -- once confident, comment this line ...
   -- EXECUTE         -- ... and uncomment this one
  (SELECT 'TRUNCATE TABLE '
       || string_agg(format('%I.%I', schemaname, tablename), ', ')
       || ' CASCADE'
   FROM   pg_tables
   WHERE  tableowner = _username
   AND    schemaname = 'public'
   );
END
$func$ LANGUAGE plpgsql;

Call:

SELECT truncate_tables('postgres');

Refined query

You don't even need a function. In Postgres 9.0+ you can execute dynamic commands in a DO statement. And in Postgres 9.5+ the syntax can be even simpler:

DO
$func$
BEGIN
   -- dangerous, test before you execute!
   RAISE NOTICE '%',  -- once confident, comment this line ...
   -- EXECUTE         -- ... and uncomment this one
   (SELECT 'TRUNCATE TABLE ' || string_agg(oid::regclass::text, ', ') || ' CASCADE'
    FROM   pg_class
    WHERE  relkind = 'r'  -- only tables
    AND    relnamespace = 'public'::regnamespace
   );
END
$func$;

About regclass and quoted table names:

• Table name as a PostgreSQL function parameter

For repeated use

Create a "template" database (let's name it my_template) with your vanilla structure and all empty tables. Then go through a DROP / CREATE DATABASE cycle:

DROP DATABASE mydb;
CREATE DATABASE mydb TEMPLATE my_template;

This is extremely fast, because Postgres copies the whole structure on the file level. No concurrency issues or other overhead slowing you down.

If concurrent connections keep you from dropping the DB, consider:

• Force drop db while others may be connected

This will solve your problem

I have a feeling the module I wrote will produce similar results to photoshop, as it preserves color data by averaging them, not applying an algorithm. It's kind of slow, but to me it is the best, because it preserves all the color data.

https://github.com/danschumann/limby-resize/blob/master/lib/canvas_resize.js

It doesn't take the nearest neighbor and drop other pixels, or sample a group and take a random average. It takes the exact proportion each source pixel should output into the destination pixel. The average pixel color in the source will be the average pixel color in the destination, which these other formulas, I think they will not be.

an example of how to use is at the bottom of https://github.com/danschumann/limby-resize

UPDATE OCT 2018: These days my example is more academic than anything else. Webgl is pretty much 100%, so you'd be better off resizing with that to produce similar results, but faster. PICA.js does this, I believe. –

If you want to wait for the executor service to finish executing, call shutdown() and then, awaitTermination(units, unitType), e.g. awaitTermination(1, MINUTE). The ExecutorService does not block on it's own monitor, so you can't use wait etc.

Tried this on Android Studio and it worked for me:

Tools > SDK Manager (Make sure to check Show Packages below)

SDK Platforms > Show Packages > Android - 28

SDK Tools > Show Packages > 28.0.3

Just a caveat to add about DateDiff, it counts the number of times you pass the boundary you specify as your units, so is subject to problems if you are looking for a precise timespan. e.g.

select datediff (m, '20100131', '20100201')

gives an answer of 1, because it crossed the boundary from January to February, so even though the span is 2 days, datediff would return a value of 1 - it crossed 1 date boundary.

select datediff(mi, '2010-01-22 15:29:55.090' , '2010-01-22 15:30:09.153')

Gives a value of 1, again, it passed the minute boundary once, so even though it is approx 14 seconds, it would be returned as a single minute when using Minutes as the units.

Please make sure your $row[1] , $row[2] contains correct value, we do assume here that 1 = Name , and 2 here is your Address field ?

Assuming you have correctly fetched your records from your Records.php, You can do something like this:

$(document).ready(function()
{
    $('#getRecords').click(function()
    {
        var response = '';
        $.ajax({ type: 'POST',   
                 url: "Records.php",   
                 async: false,
                 success : function(text){
                               $('#table1').html(text);
                           }
           });
    });

}

In your HTML

<table id="table1"> 
    //Let jQuery AJAX Change This Text  
</table>
<button id='getRecords'>Get Records</button>

A few years ago I inherited a python (2.7.1) project running under Django-1.2.3 and now was asked to enhance it with QR possibilities. Got the same problem and did not find pip or apt-get either. So I solved it in a totally different but easy way. I /bin/vi-ed the setup.py and changed the line "from setuptools import setup" into: "from distutils.core import setup" That did it for me, so I thought I should post this for other users running old pythons. Regards, Roger Vermeir

In your template, you have access to all the variables that are members of the current $scope. So, tobedone should be $scope.tobedone, and then you can display it with {{tobedone}}, or [[tobedone]] in your case.

for k, m in self.materials.items():

example:

miles_dict = {'Monday':1, 'Tuesday':2.3, 'Wednesday':3.5, 'Thursday':0.9}
for k, v in miles_dict.items():
    print("%s: %s" % (k, v))
