Technically, I have seen HTTP GET will have issues if the URL length goes beyond 2000 characters. In that case, it's better to use HTTP POST or split the URL.

$(selector).change()

.change()

.trigger("change")

Longer slower alternative, better for abstraction.

.trigger("change")

$(selector).trigger("change")

As of PostgreSQL 9.4, you can use the ? operator:

select info->>'name' from rabbits where (info->'food')::jsonb ? 'carrots';

You can even index the ? query on the "food" key if you switch to the jsonb type instead:

alter table rabbits alter info type jsonb using info::jsonb;
create index on rabbits using gin ((info->'food'));
select info->>'name' from rabbits where info->'food' ? 'carrots';

Of course, you probably don't have time for that as a full-time rabbit keeper.

Update: Here's a demonstration of the performance improvements on a table of 1,000,000 rabbits where each rabbit likes two foods and 10% of them like carrots:

d=# -- Postgres 9.3 solution
d=# explain analyze select info->>'name' from rabbits where exists (
d(# select 1 from json_array_elements(info->'food') as food
d(#   where food::text = '"carrots"'
d(# );
 Execution time: 3084.927 ms

d=# -- Postgres 9.4+ solution
d=# explain analyze select info->'name' from rabbits where (info->'food')::jsonb ? 'carrots';
 Execution time: 1255.501 ms

d=# alter table rabbits alter info type jsonb using info::jsonb;
d=# explain analyze select info->'name' from rabbits where info->'food' ? 'carrots';
 Execution time: 465.919 ms

d=# create index on rabbits using gin ((info->'food'));
d=# explain analyze select info->'name' from rabbits where info->'food' ? 'carrots';
 Execution time: 256.478 ms

This is an interesting discussion. Clearly arrays of refs are outright illegal, but IMHO the reason why is not so simple as saying 'they are not objects' or 'they have no size'. I'd point out that arrays themselves are not full-fledged objects in C/C++ - if you object to that, try instantiating some stl template classes using an array as a 'class' template parameter, and see what happens. You can't return them, assign them, pass them as parameters. ( an array param is treated as a pointer). But it is legal to make arrays of arrays. References do have a size that the compiler can and must calculate - you can't sizeof() a reference, but you can make a struct containing nothing but references. It will have a size sufficient to contain all the pointers which implement the references. You can't instantiate such a struct without initializing all the members:

struct mys {
 int & a;
 int & b;
 int & c;
};
...
int ivar1, ivar2, arr[200];
mys my_refs = { ivar1, ivar2, arr[12] };

my_refs.a += 3  ;  // add 3 to ivar1

In fact you can add this line to the struct definition

struct mys {
 ...
 int & operator[]( int i ) { return i==0?a : i==1? b : c; }
};

...and now I have something which looks a LOT like an array of refs:

int ivar1, ivar2, arr[200];
mys my_refs = { ivar1, ivar2, arr[12] };

my_refs[1] = my_refs[2]  ;  // copy arr[12] to ivar2
&my_refs[0];               // gives &my_refs.a == &ivar1

Now, this is not a real array, it's an operator overload; it won't do things that arrays normally do like sizeof(arr)/sizeof(arr[0]), for instance. But it does exactly what I want an array of references to do, with perfectly legal C++. Except (a) it's a pain to set up for more than 3 or 4 elements, and (b) it's doing a calculation using a bunch of ?: which could be done using indexing (not with normal C-pointer-calculation-semantics indexing, but indexing nonetheless). I'd like to see a very limited 'array of reference' type which can actually do this. I.e. an array of references would not be treated as a general array of things which are references, but rather it would be a new 'array-of-reference' thing which effectively maps to an internally generated class similar to the one above (but which you unfortunately can't make with templates).

this would probably work, if you don't mind this kind of nasty: recast '*this' as an array of int *'s and return a reference made from one: (not recommended, but it shows how the proper 'array' would work):

 int & operator[]( int i ) { return *(reinterpret_cast<int**>(this)[i]); }

You do

printf ("Hi %s,</br />", $name);

before setting the cookies, which isn't allowed. You can't send any output before the headers, not even a blank line.

The other answers are generally correct. I should like to contribute the modern answer. The classes Date, DateFormat and SimpleDateFormat used in most of the other answers, are long outdated and have caused trouble for many programmers over many years. Today we have so much better in java.time, AKA JSR-310, the modern Java date & time API. Can you use this on Android yet? Most certainly! The modern classes have been backported to Android in the ThreeTenABP project. See this question: How to use ThreeTenABP in Android Project for all the details.

This snippet should get you started:

    int year = 2017, month = 9, day = 28, hour = 22, minute = 45;
    LocalDateTime dateTime = LocalDateTime.of(year, month, day, hour, minute);
    DateTimeFormatter formatter = DateTimeFormatter.ofLocalizedDateTime(FormatStyle.MEDIUM);
    System.out.println(dateTime.format(formatter));

When I set my computer’s preferred language to US English or UK English, this prints:

Sep 28, 2017 10:45:00 PM

When instead I set it to Danish, I get:

28-09-2017 22:45:00

So it does follow the configuration. I am unsure exactly to what detail it follows your device’s date and time settings, though, and this may vary from phone to phone.

$Date3 = date('y-m-d');
$Date2 = date('y-m-d', strtotime("-7 days"));

SELECT * FROM disaster WHERE date BETWEEN '".$Date2."' AND  '".$Date3."'

This might be a similar problem, but you can also simply chain you commands. eg

On one line

cd ~/Sites/yourdir/web;git pull origin master

Or via SSH.

ssh [email protected] -t "cd ~/Sites/thedir/web;git pull origin master"

I tried many things (even those included in this post) but nothing worked. I decided to clear the data for the google account manager since so many mentioned to delete the account and recreate the account. It worked for my Nexus 7 (Android 4.2.2). Received 17 updates :-).

Go to Settings ? Apps ? ALL ? Google Account Manager ? Clear Data.

Reboot device.

Done.

Include jna (both "JNA" and "JNA Platform") in your library and use this function:

import com.sun.jna.Pointer;
import com.sun.jna.platform.win32.Kernel32;
import com.sun.jna.platform.win32.WinNT;
import java.lang.reflect.Field;

public static long getProcessID(Process p)
    {
        long result = -1;
        try
        {
            //for windows
            if (p.getClass().getName().equals("java.lang.Win32Process") ||
                   p.getClass().getName().equals("java.lang.ProcessImpl")) 
            {
                Field f = p.getClass().getDeclaredField("handle");
                f.setAccessible(true);              
                long handl = f.getLong(p);
                Kernel32 kernel = Kernel32.INSTANCE;
                WinNT.HANDLE hand = new WinNT.HANDLE();
                hand.setPointer(Pointer.createConstant(handl));
                result = kernel.GetProcessId(hand);
                f.setAccessible(false);
            }
            //for unix based operating systems
            else if (p.getClass().getName().equals("java.lang.UNIXProcess")) 
            {
                Field f = p.getClass().getDeclaredField("pid");
                f.setAccessible(true);
                result = f.getLong(p);
                f.setAccessible(false);
            }
        }
        catch(Exception ex)
        {
            result = -1;
        }
        return result;
    }

You can also download JNA from here and JNA Platform from here.

You need to rearrange your folders Move your tokenizers folder into nltk_data folder. This doesn't work if you have nltk_data folder containing corpora folder containing tokenizers folder

If you are OK with converting the input button to a server side control by specifying runat="server", and you are using asp.net, an option could be using the HtmlButton.OnServerClick property.

<input id="foo "runat="server" type="button" onserverclick="foo_OnClick" />

This should work and call foo_OnClick in your server side code. Also notice that based on Microsoft documentation linked above, you should also be able to use the HTML 4.0 tag.

You can instantiate an anonymous class, inject your mocks and then test that class.

@RunWith(MockitoJUnitRunner.class)
public class ClassUnderTest_Test {

    private ClassUnderTest classUnderTest;

    @Mock
    MyDependencyService myDependencyService;

    @Before
    public void setUp() throws Exception {
        this.classUnderTest = getInstance();
    }

    private ClassUnderTest getInstance() {
        return new ClassUnderTest() {

            private ClassUnderTest init(
                    MyDependencyService myDependencyService
            ) {
                this.myDependencyService = myDependencyService;
                return this;
            }

            @Override
            protected void myMethodToTest() {
                return super.myMethodToTest();
            }
        }.init(myDependencyService);
    }
}

Keep in mind that the visibility must be protected for the property myDependencyService of the abstract class ClassUnderTest.

I know maybe it is unnecessary, but I made a function which converts float to string:

CODE:

#include <stdio.h>

/** Number on countu **/

int n_tu(int number, int count)
{
    int result = 1;
    while(count-- > 0)
        result *= number;

    return result;
}

/*** Convert float to string ***/
void float_to_string(float f, char r[])
{
    long long int length, length2, i, number, position, sign;
    float number2;

    sign = -1;   // -1 == positive number
    if (f < 0)
    {
        sign = '-';
        f *= -1;
    }

    number2 = f;
    number = f;
    length = 0;  // Size of decimal part
    length2 = 0; // Size of tenth

    /* Calculate length2 tenth part */
    while( (number2 - (float)number) != 0.0 && !((number2 - (float)number) < 0.0) )
    {
         number2 = f * (n_tu(10.0, length2 + 1));
         number = number2;

         length2++;
    }

    /* Calculate length decimal part */
    for (length = (f > 1) ? 0 : 1; f > 1; length++)
        f /= 10;

    position = length;
    length = length + 1 + length2;
    number = number2;
    if (sign == '-')
    {
        length++;
        position++;
    }

    for (i = length; i >= 0 ; i--)
    {
        if (i == (length))
            r[i] = '\0';
        else if(i == (position))
            r[i] = '.';
        else if(sign == '-' && i == 0)
            r[i] = '-';
        else
        {
            r[i] = (number % 10) + '0';
            number /=10;
        }
    }
}

What is missing in the question and all the answers is that you might need the passphrase to read public data from the PKCS#12 (.pfx) keystore. If you need a passphrase or not depends on how the PKCS#12 file was created. You can check the ASN1 structure of the file (by running it through a ASN1 parser, openssl or certutil can do this too), if the PKCS#7 data (e.g. OID prefix 1.2.840.113549.1.7) is listed as 'encrypted' or with a cipher-spec or if the location of the data in the asn1 tree is below an encrypted node, you won't be able to read it without knowledge of the passphrase. It means your 'openssl pkcs12' command will fail with errors (output depends on the version). For those wondering why you might be interested in the certificate of a PKCS#12 without knowledge of the passphrase. Imagine you have many keystores and many phassphrases and you are really bad at keeping them organized and you don't want to test all combinations, the certificate inside the file could help you find out which password it might be. Or you are developing software to migrate/renew a keystore and you need to decide in advance which procedure to initiate based on the contained certicate without user interaction. So the latter examples work without passphrase depending on the PKCS#12 structure.

Just wanted to add that, because I didn't find an answer myself and spend a lot of time to figure it out.

In the accepted answer the ConcurrentBag is not required. Here's an implementation without it:

var tasks = myCollection.Select(GetData).ToList();
await Task.WhenAll(tasks);
var results = tasks.Select(t => t.Result);

Any of the "// some pre stuff" and "// some post stuff" can go into the GetData implementation (or another method that calls GetData)

Aside from being shorter, there's no use of an "async void" lambda, which is an anti pattern.

You don't need to assign names to list or [] or anything else until you wish to use it.

It's neater to use a list comprehension to make the list of names.

shuffle modifies the list you pass to it. It always returns None

If you are using a context manager (with ...) you don't need to close the file explicitly

from random import shuffle

with open('names') as f:
    names = [name.rstrip() for name in f if not name.isspace()]
    shuffle(names)

assert len(names) > 100

Ended up writing this today and seems to be ok. Your usage could be:

await TaskEx.WaitUntil(isExcelInteractive);

code (including the inverse operation)

public static class TaskEx
{
    /// <summary>
    /// Blocks while condition is true or timeout occurs.
    /// </summary>
    /// <param name="condition">The condition that will perpetuate the block.</param>
    /// <param name="frequency">The frequency at which the condition will be check, in milliseconds.</param>
    /// <param name="timeout">Timeout in milliseconds.</param>
    /// <exception cref="TimeoutException"></exception>
    /// <returns></returns>
    public static async Task WaitWhile(Func<bool> condition, int frequency = 25, int timeout = -1)
    {
        var waitTask = Task.Run(async () =>
        {
            while (condition()) await Task.Delay(frequency);
        });

        if(waitTask != await Task.WhenAny(waitTask, Task.Delay(timeout)))
            throw new TimeoutException();
    }

    /// <summary>
    /// Blocks until condition is true or timeout occurs.
    /// </summary>
    /// <param name="condition">The break condition.</param>
    /// <param name="frequency">The frequency at which the condition will be checked.</param>
    /// <param name="timeout">The timeout in milliseconds.</param>
    /// <returns></returns>
    public static async Task WaitUntil(Func<bool> condition, int frequency = 25, int timeout = -1)
    {
        var waitTask = Task.Run(async () =>
        {
            while (!condition()) await Task.Delay(frequency);
        });

        if (waitTask != await Task.WhenAny(waitTask, 
                Task.Delay(timeout))) 
            throw new TimeoutException();
    }
}

You can use the crosstab() function of the additional module tablefunc - which you have to install once per database. Since PostgreSQL 9.1 you can use CREATE EXTENSION for that:

CREATE EXTENSION tablefunc;

In your case, I believe it would look something like this:

CREATE TABLE t (Section CHAR(1), Status VARCHAR(10), Count integer);

INSERT INTO t VALUES ('A', 'Active',   1);
INSERT INTO t VALUES ('A', 'Inactive', 2);
INSERT INTO t VALUES ('B', 'Active',   4);
INSERT INTO t VALUES ('B', 'Inactive', 5);

SELECT row_name AS Section,
       category_1::integer AS Active,
       category_2::integer AS Inactive
FROM crosstab('select section::text, status, count::text from t',2)
            AS ct (row_name text, category_1 text, category_2 text);

From a script (one that works):

CREATE DATABASE Northwind
ON ( FILENAME = 'C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\Northwind.mdf' )
LOG ON ( FILENAME = 'C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA\Northwind_log.ldf')
GO

obviously update the path:

C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA

To where your .mdf and .ldf reside.

Here's an interactive session showing some of the steps in @TokenMacGuy's one-liner. First he uses the map function to convert each item in the list to a string (actually, he's making a new list, not converting the items in the old list). Then he's using the string method join to combine those strings with ', ' between them. The rest is just string formatting, which is pretty straightforward. (Edit: this instance is straightforward; string formatting in general can be somewhat complex.)

Note that using join is a simple and efficient way to build up a string from several substrings, much more efficient than doing it by successively adding strings to strings, which involves a lot of copying behind the scenes.

>>> mylist = ['x', 3, 'b']
>>> m = map(str, mylist)
>>> m
['x', '3', 'b']
>>> j = ', '.join(m)
>>> j
'x, 3, b'

There are several ways to approach this. Personally, I would avoid in-line scripting. Since you've tagged jQuery, let's use that.

HTML:

<form>
    <input type="text" id="formValueId" name="valueId"/>
    <input type="button" id="myButton" />
</form>

JavaScript:

$(document).ready(function() {
    $('#myButton').click(function() {
      foo($('#formValueId').val());
    });
});

Try this one:

<body onload="imageRefreshBig();">

Also you might want to check Javascript console for errors (in Chrome it's under Shift + Ctrl + J).

In my case I had installed a new version of netbeans and upgraded from java 7 to 8. The new netbeans had a different version of glassfish, so I opened the properties of my project and pointed it to the right glassfish version and set the jdk to version 8.

bool isPow2 = ((x & ~(x-1))==x)? !!x : 0;

As previously stated, it's not directly possible, but you can set up Apache or nginx + SSL on a EC2 instance, CNAME your desired domain to that, and reverse-proxy to the (non-custom domain) S3 URLs.

var url = window.location;
var urlAux = url.split('=');
var img_id = urlAux[1]

Worked for me. But the first var should be var url = window.location.href

Use the load event:

img = new Image();

img.onload = function(){
  // image  has been loaded
};

img.src = image_url;

Also have a look at:

• Preloading and the JavaScript Image() object

If you use bootstrap, you might use this -

 <img src="{{URL::asset('/image/propic.png')}}" alt="profile Pic" height="200" width="200">

note: inside public folder create a new folder named image then put your images there. Using URL::asset() you can directly access to the public folder.

When you find it necessary to update a primary key value as well as all matching foreign keys, then the entire design needs to be fixed.

It is tricky to cascade all the necessary foreign keys changes. It is a best practice to never update the primary key, and if you find it necessary, you should use a Surrogate Primary Key, which is a key not derived from application data. As a result its value is unrelated to the business logic and never needs to change (and should be invisible to the end user). You can then update and display some other column.

for example:

BadUserTable
UserID     varchar(20) primary key --user last name
other columns...

when you create many tables that have a FK to UserID, to track everything that the user has worked on, but that user then gets married and wants a ID to match their new last name, you are out of luck.

GoodUserTable
UserID    int identity(1,1) primary key
UserLogin varchar(20) 
other columns....

you now FK the Surrogate Primary Key to all the other tables, and display UserLogin when necessary, allow them to login using that value, and when they need to change it, you change it in one column of one row only.

Just saw a variation on this issue: I went into the project.pbxproj file as per Brad Smith's notes above, except in this case all of the PROVISIONING_PROFILE lines seemed to be correct, with no occurrence of the "bad" profile string that Xcode couldn't find.

However, the fix was the same: deleting ALL of the PROVISIONING_PROFILE lines in project.pbxproj, even though they looked "good" in theory, and then reopening the project in Xcode.

As the options here didn't work for me, I'm sharing how I solved it:

My project has a parent project (with its own pom.xml) that has many children modules, one of which (A) has a dependency to another child (B). When I tried mvn package in A, it didn't work because B could not be resolved.

Executing mvn install in the parent directory did the job. After that, I could do mvn package inside of A and only then it could find B.

No, not directly in the std::list template itself. You can however use std::find algorithm like that:

std::list<int> my_list;
//...
int some_value = 12;
std::list<int>::iterator iter = std::find (my_list.begin(), my_list.end(), some_value);
// now variable iter either represents valid iterator pointing to the found element,
// or it will be equal to my_list.end()

Find your spinner name and find id then implement this method.

spinnername.setOnItemSelectedListener(new OnItemSelectedListener() {

    @Override
    public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
        // your code here
    }

    @Override
    public void onNothingSelected(AdapterView<?> parentView) {
        // your code here
    }
});

Just another information... Had that problem today on a Windows 2012 R2 x64 TS system where the application was started from a unc/network path. The issue occured for one application for all terminal server users. Executing the application locally worked without problems. After a reboot it started working again - the SEHException's thrown had been Constructor init and TargetInvocationException

The following may not be the best method--it is O(n^2). However, it should serve to get the job done (eventually).

count_of_elements_so_far = 0;
for (each element in linked list)
{
    search for current element in first <count_of_elements_so_far>
    if found, then you have a loop
    else,count_of_elements_so_far++;
}

The problem is that you are not logged in as a root user (which you don't want). You need to create a certificate for gdb to be allowed access. Follow this tutorial and you should be good to go...

If all else fails, just use: sudo gdb executableFileName

Here's a short snippet using subprocess. The check_call method either returns 0 for success, or raises an exception. This way, I don't have to parse the output of ping. I'm using shlex to split the command line arguments.

  import subprocess
  import shlex

  command_line = "ping -c 1 www.google.comsldjkflksj"
  args = shlex.split(command_line)
  try:
      subprocess.check_call(args,stdout=subprocess.PIPE,stderr=subprocess.PIPE)
      print "Website is there."
  except subprocess.CalledProcessError:
      print "Couldn't get a ping."

Judging by the documentation for date/time functions, you should be able to do something like:

SELECT * FROM FOO
WHERE MY_DATE_FIELD >= NOW() - INTERVAL 1 DAY

Alright, this is probably the easiest way to do it:

1. First of all, you will have to install GAPPS.
2. Next, open the virtual box and wait for the home screen to show up on Genymotion.
3. Drag and drop the GAPPS folder that you had downloaded earlier on into Genymotion.
4. You would get a prompt. Click OK. You would see a lot of errors, but just ignore them and wait for the successful prompt to come up. Click OK again and restart the virtual device.
5. A Google account screen should show up. Open up the playstore app if it doesn't show up. Sign into your account. Again ignore the errors.
6. The playstore should open now and should be fully functional.

The second line should have been pixels[0], with an S. You probably have a tuple named pixel, and tuples are immutable. Construct new pixels instead:

image = Image.open('balloon.jpg')

pixels = [(pix[0] + 20,) + pix[1:] for pix in image.getdata()]

image.putdate(pixels)

$(FORM_ID).validate().resetForm(); is still not working as expected.

I am clearing form with resetForm(). It works in all case except one!!

When I load any form via Ajax and apply form validation after loading my dynamic HTML, then after when I try to reset the form with resetForm() and it fails and also it flushed off all validation I am applying on form elements.

So kindly do not use this for Ajax loaded forms OR manually initialized validation.

P.S. You need to use Nick Craver's answer for such scenario as I explained.

You can get that error if you have an object with the same name as the schema. For example:

create sequence s2;

begin
  s2.a;
end;
/

ORA-06550: line 2, column 6:
PLS-00302: component 'A' must be declared
ORA-06550: line 2, column 3:
PL/SQL: Statement ignored

When you refer to S2.MY_FUNC2 the object name is being resolved so it doesn't try to evaluate S2 as a schema name. When you just call it as MY_FUNC2 there is no confusion, so it works.

The documentation explains name resolution. The first piece of the qualified object name - S2 here - is evaluated as an object on the current schema before it is evaluated as a different schema.

It might not be a sequence; other objects can cause the same error. You can check for the existence of objects with the same name by querying the data dictionary.

select owner, object_type, object_name
from all_objects
where object_name = 'S2';

You can use JSONPath

Doing something like this:

results = JSONPath(null, TestObj, "$..[?(@.id=='A')]")

Note that JSONPath returns an array of results

(I have not tested the expression "$..[?(@.id=='A')]" btw. Maybe it needs to be fine-tuned with the help of a browser console)

import os
os.path.exists(path) # Returns whether the path (directory or file) exists or not
os.path.isfile(path) # Returns whether the file exists or not

Microsoft Visio is probably the best I've came across, although as far as I know it won't automatically generate based on your relationships.

EDIT: try this in Visio, could give you what you need http://office.microsoft.com/en-us/visio-help/reverse-engineering-an-existing-database-HA001182257.aspx

@fooMonster article worked for me

# git ls-tree HEAD
100644 blob 55c0287d4ef21f15b97eb1f107451b88b479bffe    script.sh

As you can see the file has 644 permission (ignoring the 100). We would like to change it to 755:

# git update-index --chmod=+x script.sh

commit the changes

# git commit -m "Changing file permissions"
[master 77b171e] Changing file permissions
0 files changed, 0 insertions(+), 0 deletions(-)
mode change 100644 => 100755 script.sh

Assuming the following command works successfully:

mysql -u username -p -h remote.site.com

The syntax for mysqldump is identical, and outputs the database dump to stdout. Redirect the output to a local file on the computer:

mysqldump -u username -p -h remote.site.com DBNAME > backup.sql

Replace DBNAME with the name of the database you'd like to download to your computer.

Try:

<xsl:value-of select="count(preceding-sibling::*) + 1" />

Edit - had a brain freeze there, position() is more straightforward!

Although M-x eval-buffer will work you may run into problems with toggles and other similar things. A better approach might be to "mark" or highlight whats new in your .emacs (or even scratch buffer if your just messing around) and then M-x eval-region. Hope this helps.

Use the reset function, which is available on the form element.

var form = document.getElementById("myForm");
form.reset();

Since ID is auto increment, you can also specify ID=NULL as,

LOAD XML LOCAL INFILE '/pathtofile/file.xml' INTO TABLE my_tablename SET ID=NULL;

first in powershell type

$env:NODE_ENV="production"

then type

node fileName.js

It will work perfectly displaying all the outputs.

The following batch commands are used to delete all your temp, recent and prefetch files on your System.

        private void DisableButtons()
    {
        foreach (var ctl in Controls.OfType<Button>())
        {
            ctl.Enabled = false;
        }
    }

    private void EnableButtons()
    {
        foreach (var ctl in Controls.OfType<Button>())
        {
            ctl.Enabled = true;
        }
    }

Can't be done as it stands... The code

def myMethod(pParm1='1', pParm2='2'){
    println "${pParm1}${pParm2}"
}

Basically makes groovy create the following methods:

Object myMethod( pParm1, pParm2 ) {
    println "$pParm1$pParm2"
}

Object myMethod( pParm1 ) {
    this.myMethod( pParm1, '2' )
}

Object myMethod() {
    this.myMethod( '1', '2' )
}

One alternative would be to have an optional Map as the first param:

def myMethod( Map map = [:], String mandatory1, String mandatory2 ){
    println "${mandatory1} ${mandatory2} ${map.parm1 ?: '1'} ${map.parm2 ?: '2'}"
}

myMethod( 'a', 'b' )                // prints 'a b 1 2'
myMethod( 'a', 'b', parm1:'value' ) // prints 'a b value 2'
myMethod( 'a', 'b', parm2:'2nd')    // prints 'a b 1 2nd'

Obviously, documenting this so other people know what goes in the magical map and what the defaults are is left to the reader ;-)

# Json to object
$obj = $obj | ConvertFrom-Json

In the client side handle the click event of the button, use the ClientID property to get he id of the button:

$(document).ready(function() {
$("#<%=myButton.ClientID %>,#<%=muSecondButton.ClientID%>").click(

    function() {
     $.get("/myPage.aspx",{id:$(this).attr('id')},function(data) {
       // do something with the data
     return false;
     }
    });
 });

In your page on the server:

protected void Page_Load(object sender,EventArgs e) {
 // check if it is an ajax request
 if (Request.Headers["X-Requested-With"] == "XMLHttpRequest") {
  if (Request.QueryString["id"]==myButton.ClientID) {
    // call the click event handler of the myButton here
    Response.End();
  }
  if (Request.QueryString["id"]==mySecondButton.ClientID) {
    // call the click event handler of the mySecondButton here
    Response.End();
  }
 }
}

If you want to find the button only by its class name and using jQLite only, you can do like below:

var myListButton = $document.find('button').filter(function() {
    return angular.element(this).hasClass('multi-files');
});

Hope this helps. :)

In Spring or Spring boot application.properties file here is the way to escape the special characters;

With Oracle 11g R2 (at least with 11.2.02) there is a view named datapump_dir_objs.

SELECT * FROM datapump_dir_objs;

The view shows the NAME of the directory object, the PATH as well as READ and WRITE permissions for the currently connected user. It does not show any directory objects which the current user has no permission to read from or write to, though.

If you want to get the navigation bar height, use the maxY property that considers the safeArea size as well, like this:

 let height = navigationController?.navigationBar.frame.maxY  

Mac OS X Answer

You don't have write access to the node_modules directory

npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules

Add your User to the directory with write access

1. Open folder containing node_modules

   open /usr/local/lib/

2. Do a cmd+I on the node_modules folder to open the permission dialog
3. Add your user to have read and write access in the sharing and permissions section

Yes you could use an <input type="hidden" /> and set the value of that hidden field in your javascript code so it gets posted with your other form data.

Go into Simulator-> Hardware->Keyboard and unchecking Connect Hardware Keyboard.

The same as many answers above BUT did not change for me until I quit and restart the simulator. xcode 8.2.1 and Simulator 10.0.

Here is how it worked beautifully for me. In the window resources add the image.

   <Image x:Key="delImg" >
    <Image.Source>
     <BitmapImage UriSource="Images/delitem.gif"></BitmapImage>
    </Image.Source>
   </Image>

Then the code goes like this.

Image img = new Image()

img.Source = ((Image)this.Resources["delImg"]).Source;

"this" is referring to the Window object

My cryptic version...

I ran into the same problem.

I downloaded the 'popper.min.js' file from the CDN on the bootstrap website.

See here: https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.11.0/umd/popper.min.js

Easier than compiling the project.

Important: You must include popper after jquery but BEFORE bootstrap.

Just make sure that you have one root div and put everything inside this root

  <div class="root">
    <!--and put all child here --!>
   <div class='child1'></div>
   <div class='child2'></div>
  </div>

and so on

Here is another method using .loc to replace inf with nan on a Series:

s.loc[(~np.isfinite(s)) & s.notnull()] = np.nan

So, in response to the original question:

df = pd.DataFrame(np.ones((3, 3)), columns=list('ABC'))

for i in range(3): 
    df.iat[i, i] = np.inf

df
          A         B         C
0       inf  1.000000  1.000000
1  1.000000       inf  1.000000
2  1.000000  1.000000       inf

df.sum()
A    inf
B    inf
C    inf
dtype: float64

df.apply(lambda s: s[np.isfinite(s)].dropna()).sum()
A    2
B    2
C    2
dtype: float64

Just use JSONObject.toString(); method. And have a look at OkHttp's tutorial:

public static final MediaType JSON
    = MediaType.parse("application/json; charset=utf-8");

OkHttpClient client = new OkHttpClient();

String post(String url, String json) throws IOException {
  RequestBody body = RequestBody.create(JSON, json); // new
  // RequestBody body = RequestBody.create(JSON, json); // old
  Request request = new Request.Builder()
      .url(url)
      .post(body)
      .build();
  Response response = client.newCall(request).execute();
  return response.body().string();
}

The problem is frequently with 'secure' setup of mountpoints, such as /tmp

If they are mounted noexec (check with cat /etc/mtab and or sudo mount) then there is no permission to execute any binaries or build scripts from within the (temporary) folder.

E.g. to remount temporarily:

 sudo mount -o remount,exec /tmp

Or to change permanently, remove noexec in /etc/fstab

This happened to me because I put a variable in the regex and sometimes its string value included a slash. Solution: preg_quote.

I found this article

        g.TranslateTransform(-offset.X, -offset.Y);

        //draw passed in image onto graphics object
        g.DrawImage(image, new PointF(0, 0));

        return rotatedBmp;
    }

I did a log file which prints data into text file using "Winston" log. The source code is here below,

var array4=[];

array1[0]  =  78;`
array1[1]  =  56;
array1[2]  =  24;
array1[3]  =  34;

for (var n=0;n<4;n++)
{
array2[n]=array1[n].toString();
}

for (var k=0;k<4;k++)

1. Create your shell script as login.sh in your $HOME folder.

2. Paste the following one-line script into Script Editor:

   do shell script "$HOME/login.sh"

3. Then save it as an application.

4. Finally add the application to your login items.

If you want to make the script output visual, you can swap step 2 for this:

tell application "Terminal"
  activate
  do script "$HOME/login.sh"
end tell

If multiple commands are needed something like this can be used:

tell application "Terminal"
  activate
  do script "cd $HOME"
  do script "./login.sh" in window 1
end tell

This is my solution. First we start with 1, we loop over the array and compare with 2 elements from the array, if it matches one of the element we increment by 1 and start the process all over again.

private static int findSmallest(int max, int[] A) {

    if (A == null || A.length == 0)
        return max;

    for (int i = 0; i < A.length; i++) {
        if (i == A.length - 1) {
            if (max != A[i])
                return max;
            else
                return max + 1;
        } else if (!checkIfUnique(max, A[i], A[i + 1]))
            return findSmallest(max + 1, A);
    }
    return max;
}


private static boolean checkIfUnique(int number, int n1, int n2) {
    return number != n1 && number != n2;
}

int (*x)() is not a pointer to member function. A pointer to member function is written like this: int (A::*x)(void) = &A::f;.

A simple function that blits an image front onto an image back and returns the result. It works with both 3 and 4-channel images and deals with the alpha channel. Overlaps are handled as well.

The output image has the same size as back, but always 4 channels.
The output alpha channel is given by (u+v)/(1+uv) where u,v are the alpha channels of the front and back image and -1 <= u,v <= 1. Where there is no overlap with front, the alpha value from back is taken.

import cv2

def merge_image(back, front, x,y):
    # convert to rgba
    if back.shape[2] == 3:
        back = cv2.cvtColor(back, cv2.COLOR_BGR2BGRA)
    if front.shape[2] == 3:
        front = cv2.cvtColor(front, cv2.COLOR_BGR2BGRA)

    # crop the overlay from both images
    bh,bw = back.shape[:2]
    fh,fw = front.shape[:2]
    x1, x2 = max(x, 0), min(x+fw, bw)
    y1, y2 = max(y, 0), min(y+fh, bh)
    front_cropped = front[y1-y:y2-y, x1-x:x2-x]
    back_cropped = back[y1:y2, x1:x2]

    alpha_front = front_cropped[:,:,3:4] / 255
    alpha_back = back_cropped[:,:,3:4] / 255
    
    # replace an area in result with overlay
    result = back.copy()
    print(f'af: {alpha_front.shape}\nab: {alpha_back.shape}\nfront_cropped: {front_cropped.shape}\nback_cropped: {back_cropped.shape}')
    result[y1:y2, x1:x2, :3] = alpha_front * front_cropped[:,:,:3] + alpha_back * back_cropped[:,:,:3]
    result[y1:y2, x1:x2, 3:4] = (alpha_front + alpha_back) / (1 + alpha_front*alpha_back) * 255

    return result

import networkx as nx

g.add_edge(3,5)
g.add_edge(2,3)

This is just simple how to draw directed graph using python 3.x using networkx. just simple representation and can be modified and colored etc. See the generated graph here.

Note: It's just a simple representation. Weighted Edges could be added like

g.add_edges_from([(1,2),(2,5)], weight=2)

and hence plotted again.

A Date object's underlying value is actually in UTC. To prove this, notice that if you type new Date(0) you'll see something like: Wed Dec 31 1969 16:00:00 GMT-0800 (PST). 0 is treated as 0 in GMT, but .toString() method shows the local time.

Big note, UTC stands for Universal time code. The current time right now in 2 different places is the same UTC, but the output can be formatted differently.

What we need here is some formatting

var _date = new Date(1270544790922); 
// outputs > "Tue Apr 06 2010 02:06:30 GMT-0700 (PDT)", for me
_date.toLocaleString('fi-FI', { timeZone: 'Europe/Helsinki' });
// outputs > "6.4.2010 klo 12.06.30"
_date.toLocaleString('en-US', { timeZone: 'Europe/Helsinki' });
// outputs > "4/6/2010, 12:06:30 PM"

This works but.... you can't really use any of the other date methods for your purposes since they describe the user's timezone. What you want is a date object that's related to the Helsinki timezone. Your options at this point are to use some 3rd party library (I recommend this), or hack-up the date object so you can use most of it's methods.

Option 1 - a 3rd party like moment-timezone

moment(1270544790922).tz('Europe/Helsinki').format('YYYY-MM-DD HH:mm:ss')
// outputs > 2010-04-06 12:06:30
moment(1270544790922).tz('Europe/Helsinki').hour()
// outputs > 12

This looks a lot more elegant than what we're about to do next.

Option 2 - Hack up the date object

var currentHelsinkiHoursOffset = 2; // sometimes it is 3
var date = new Date(1270544790922);
var helsenkiOffset = currentHelsinkiHoursOffset*60*60000;
var userOffset = _date.getTimezoneOffset()*60000; // [min*60000 = ms]
var helsenkiTime = new Date(date.getTime()+ helsenkiOffset + userOffset);
// Outputs > Tue Apr 06 2010 12:06:30 GMT-0700 (PDT)

It still thinks it's GMT-0700 (PDT), but if you don't stare too hard you may be able to mistake that for a date object that's useful for your purposes.

I conveniently skipped a part. You need to be able to define currentHelsinkiOffset. If you can use date.getTimezoneOffset() on the server side, or just use some if statements to describe when the time zone changes will occur, that should solve your problem.

Conclusion - I think especially for this purpose you should use a date library like moment-timezone.

I can't take any credit for this, but this one I found worked really well for my needs. shouldAllowSelfSignedCert is my BOOL variable. Just add to your NSURLConnection delegate and you should be rockin for a quick bypass on a per connection basis.

- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)space {
     if([[space authenticationMethod] isEqualToString:NSURLAuthenticationMethodServerTrust]) {
          if(shouldAllowSelfSignedCert) {
               return YES; // Self-signed cert will be accepted
          } else {
               return NO;  // Self-signed cert will be rejected
          }
          // Note: it doesn't seem to matter what you return for a proper SSL cert
          //       only self-signed certs
     }
     // If no other authentication is required, return NO for everything else
     // Otherwise maybe YES for NSURLAuthenticationMethodDefault and etc.
     return NO;
}

Application.ActiveWorkbook.Worksheets("data").Range("C1", "C20000").NumberFormat = "yyyy-mm-dd"

It depends on what you mean by "multiple lines". Different operating systems use different line separators.

In Java, \r is always carriage return, and \n is line feed. On Unix, just \n is enough for a newline, whereas many programs on Windows require \r\n. You can get at the platform default newline use System.getProperty("line.separator") or use String.format("%n") as mentioned in other answers.

But really, you need to know whether you're trying to produce OS-specific newlines - for example, if this is text which is going to be transmitted as part of a specific protocol, then you should see what that protocol deems to be a newline. For example, RFC 2822 defines a line separator of \r\n and this should be used even if you're running on Unix. So it's all about context.

An error in your httpd.conf or other Apache config files will cause this. Revert httpd.conf et al to the pristine, installer versions and see if Apache runs again.

(I tried Skype and other suggestions here, no luck, but logs [XAMPP > Apache > Logs button] showed that it ran once when first installed. That was the giveaway.)

Likely errors:

• Did you edit with a Windows text editor that changes line endings to non-Unix? (Solution here.)
• Missing or invalid DSO files (.so)

Before making any changes in Tomcat Server Location, you need to remove project(s) deployed on server.

To remove project: expand tomcat server in "Servers" view
right click and select remove

Or as a single command:

git push -u origin master:my_test

Pushes the commits from your local master branch to a (possibly new) remote branch my_test and sets up master to track origin/my_test.

There are vary solutions about this, but I couldn't find a whole thing. So I made my own solution for :

nicinfo

How to use :

NICInfoSummary* summary = [[[NICInfoSummary alloc] init] autorelease];

// en0 is for WiFi 
NICInfo* wifi_info = [summary findNICInfo:@"en0"];

// you can get mac address in 'XX-XX-XX-XX-XX-XX' form
NSString* mac_address = [wifi_info getMacAddressWithSeparator:@"-"];

// ip can be multiple
if(wifi_info.nicIPInfos.count > 0)
{
    NICIPInfo* ip_info = [wifi_info.nicIPInfos objectAtIndex:0];
    NSString* ip = ip_info.ip;
    NSString* netmask = ip_info.netmask;
    NSString* broadcast_ip = ip_info.broadcastIP;
}
else
{
    NSLog(@"WiFi not connected!");
}

I have faced the same issue using Google Chrome browser. Same website was opening normally using the incognito mode and different browsers. At first, I cleared cached files and cookies over the past 24 hours, but this didn't help.

I realized that my first visit to the website was during the past 10 days. So, I cleared cached files and cookies over the past 4 weeks and that resolved the problem.
Note: I didn't clear my browsing history data

Just came across this googling for a solution. Actually, there is one in Ansible 2.5. You can specify your inventory file with --inventory, like this: ansible --inventory configs/hosts --list-hosts all

I'm currently in the process of building a single page application. Here is what I have thus far that I believe would be answering your question. I have a base template (base.html) that has a div with the ng-view directive in it. This directive tells angular where to put the new content in. Note that I'm new to angularjs myself so I by no means am saying this is the best way to do it.

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

app.config(function($routeProvider, $locationProvider) {                        
  $routeProvider                                                                
       .when('/home/', {                                            
         templateUrl: "templates/home.html",                                               
         controller:'homeController',                                
        })                                                                      
        .when('/about/', {                                       
            templateUrl: "templates/about.html",     
            controller: 'aboutController',  
        }) 
        .otherwise({                      
            template: 'does not exists'   
        });      
});

app.controller('homeController', [              
    '$scope',                              
    function homeController($scope,) {        
        $scope.message = 'HOME PAGE';                  
    }                                                
]);                                                  

app.controller('aboutController', [                  
    '$scope',                               
    function aboutController($scope) {        
        $scope.about = 'WE LOVE CODE';                       
    }                                                
]);

I'm not sure how you want to use the file names, but one of these should help:

• If you just want to see the names, you can use something like gulp-debug, which lists the details of the vinyl file. Insert this anywhere you want a list, like so:

  var gulp = require('gulp'),
      debug = require('gulp-debug');
  
  gulp.task('examples', function() {
      return gulp.src('./examples/*.html')
          .pipe(debug())
          .pipe(gulp.dest('./build'));
  });
  

• Another option is gulp-filelog, which I haven't used, but sounds similar (it might be a bit cleaner).

• Another options is gulp-filesize, which outputs both the file and it's size.

• If you want more control, you can use something like gulp-tap, which lets you provide your own function and look at the files in the pipe.

I like to used this method the most, it will auto select the first column to the last column being used. However, if the last cell in the first row or the last cell in the first column are empty, this code will not calculate properly. Check the link for other methods to dynamically select cell range.

Sub DynamicRange()
'Best used when first column has value on last row and first row has a value in the last column

Dim sht As Worksheet
Dim LastRow As Long
Dim LastColumn As Long
Dim StartCell As Range

Set sht = Worksheets("Sheet1")
Set StartCell = Range("A1")

'Find Last Row and Column
  LastRow = sht.Cells(sht.Rows.Count, StartCell.Column).End(xlUp).Row
  LastColumn = sht.Cells(StartCell.Row, sht.Columns.Count).End(xlToLeft).Column

'Select Range
  sht.Range(StartCell, sht.Cells(LastRow, LastColumn)).Select

End Sub

I was looking long and hard for a solution to this problem and the best I found was a root FTP server on the phone that you connect to on Windows with an FTP client like FileZilla, on the same WiFi network of course.

The root FTP server app I ended up using is FTP Droid. I tried a lot of other FTP apps with bigger download numbers but none of them worked for me for whatever reason. So install this app and set a user with home as / or wherever you want.

Then make note of the phone IP and connect with FileZilla and you should have access to the root of the phone. The biggest benefit I found is I can download entire folders and FTP will just queue it up and take care of it. So I downloaded all of my /data/data/ folder when I was looking for an app and could search on my PC. Very handy.

Posting my full function based on Kindall's solution. I was able to support any alphanumeric characters mixed in with the numbers by padding each version section with leading zeros.

While certainly not as pretty as his one-liner function, it seems to work well with alpha-numeric version numbers. (Just be sure to set the zfill(#) value appropriately if you have long strings in your versioning system.)

def versiontuple(v):
   filled = []
   for point in v.split("."):
      filled.append(point.zfill(8))
   return tuple(filled)

.

>>> versiontuple("10a.4.5.23-alpha") > versiontuple("2a.4.5.23-alpha")
True


>>> "10a.4.5.23-alpha" > "2a.4.5.23-alpha"
False

Example:

Let's say table A has two children B and C. Then we can use the following syntax to drop all tables.

DROP TABLE IF EXISTS B,C,A;

This can be placed in the beginning of the script instead of individually dropping each table.

@Entity(name = "someThing") => this name will be used to name the Entity
@Table(name = "someThing")  => this name will be used to name a table in DB

So, in the first case your table and entity will have the same name, that will allow you to access your table with the same name as the entity while writing HQL or JPQL.

And in second case while writing queries you have to use the name given in @Entity and the name given in @Table will be used to name the table in the DB.

So in HQL your someThing will refer to otherThing in the DB.

That's because if a class is abstract, then by definition you are required to create subclasses of it to instantiate. The subclasses will be required (by the compiler) to implement any interface methods that the abstract class left out.

Following your example code, try making a subclass of AbstractThing without implementing the m2 method and see what errors the compiler gives you. It will force you to implement this method.

I`d like to add to the already good answers:

The symbols '+', '*' and '-' are sometimes used as shorthand in some older textbooks for OR,? and AND,? and NOT,¬ logical operators in Bool`s algebra. In C/C++ of course we use "and","&&" and "or","||" and "not","!".

Watch out: "true + true" evaluates to 2 in C/C++ via internal representation of true and false as 1 and 0, and the implicit cast to int!

int main ()
{
  std::cout <<  "true - true = " << true - true << std::endl;
// This can be used as signum function:
// "(x > 0) - (x < 0)" evaluates to +1 or -1 for numbers.
  std::cout <<  "true - false = " << true - false << std::endl;
  std::cout <<  "false - true = " << false - true << std::endl;
  std::cout <<  "false - false = " << false - false << std::endl << std::endl;

  std::cout <<  "true + true = " << true + true << std::endl;
  std::cout <<  "true + false = " << true + false << std::endl;
  std::cout <<  "false + true = " << false + true << std::endl;
  std::cout <<  "false + false = " << false + false << std::endl << std::endl;

  std::cout <<  "true * true = " << true * true << std::endl;
  std::cout <<  "true * false = " << true * false << std::endl;
  std::cout <<  "false * true = " << false * true << std::endl;
  std::cout <<  "false * false = " << false * false << std::endl << std::endl;

  std::cout <<  "true / true = " << true / true << std::endl;
  //  std::cout <<  true / false << std::endl; ///-Wdiv-by-zero
  std::cout <<  "false / true = " << false / true << std::endl << std::endl;
  //  std::cout <<  false / false << std::endl << std::endl; ///-Wdiv-by-zero

  std::cout <<  "(true || true) = " << (true || true) << std::endl;
  std::cout <<  "(true || false) = " << (true || false) << std::endl;
  std::cout <<  "(false || true) = " << (false || true) << std::endl;
  std::cout <<  "(false || false) = " << (false || false) << std::endl << std::endl;

  std::cout <<  "(true && true) = " << (true && true) << std::endl;
  std::cout <<  "(true && false) = " << (true && false) << std::endl;
  std::cout <<  "(false && true) = " << (false && true) << std::endl;
  std::cout <<  "(false && false) = " << (false && false) << std::endl << std::endl;

}

yields :

true - true = 0
true - false = 1
false - true = -1
false - false = 0

true + true = 2
true + false = 1
false + true = 1
false + false = 0

true * true = 1
true * false = 0
false * true = 0
false * false = 0

true / true = 1
false / true = 0

(true || true) = 1
(true || false) = 1
(false || true) = 1
(false || false) = 0

(true && true) = 1
(true && false) = 0
(false && true) = 0
(false && false) = 0

You won't need a plugin to see commit history with Visual Studio Code 1.42 or more.

Timeline view

In this milestone, we've made progress on the new Timeline view, and have an early preview to share.
This is a unified view for visualizing time-series events (e.g. commits, saves, test runs, etc.) for a resource (file, folder, etc.).

To enable the Timeline view, you must be using the Insiders Edition (VSCode 1.44 March 2020) and then add the following setting:

"timeline.showView": true

Click on the error message displaying "Unbound classpath container: 'JRE System Library[jdk1.5.0_08]", left click anyd choose quick fix. Under quick, list of possible options will get displated. Choose replace library. Choose the library you installed. Your good to go.

Add sudo to your command line, like:

$ sudo firebase init

yum install php72-php-bcmath.x86_64
cp /etc/opt/remi/php72/php.d/20-bcmath.ini /etc/php.d/
cp /opt/remi/php72/root/usr/lib64/php/modules/bcmath.so /usr/lib64/php/modules/
systemctl restart httpd

Not sure why I had to go so deep considering the yum install gave me bcmath in phpinfo()

If you use the Geolocation API, it would be as simple as using the following code.

navigator.geolocation.getCurrentPosition(function(location) {
  console.log(location.coords.latitude);
  console.log(location.coords.longitude);
  console.log(location.coords.accuracy);
});

You may also be able to use Google's Client Location API.

This issue has been discussed in Is it possible to detect a mobile browser's GPS location? and Get position data from mobile browser. You can find more information there.

Other that the differences in the default access (public/private), there is no difference.

However, some shops that code in C and C++ will use "class/struct" to indicate that which can be used in C and C++ (struct) and which are C++ only (class). In other words, in this style all structs must work with C and C++. This is kind of why there was a difference in the first place long ago, back when C++ was still known as "C with Classes."

Note that C unions work with C++, but not the other way around. For example

union WorksWithCppOnly{
    WorksWithCppOnly():a(0){}
    friend class FloatAccessor;
    int a;
private:
    float b;
};

And likewise

typedef union friend{
    int a;
    float b;
} class;

only works in C

Just set Label AutoSize property to False. Then the text will be wrapped and you can re-size the control manually to show the text.

In some rare cases you might want to implement your own String serialization.

But that probably is a bad idea unless you know what you are doing. (e.g. serializing for I/O with a batch file)

Something like that would do the trick (and it would be easy to edit by hand/batch), but be careful that some more checks should be done, like that name doesn't contain a newline.

public string name {get;set;}
public int age {get;set;}

Person(string serializedPerson) 
{
    string[] tmpArray = serializedPerson.Split('\n');
    if(tmpArray.Length>2 && tmpArray[0].Equals("#")){
        this.name=tmpArray[1];
        this.age=int.TryParse(tmpArray[2]);
    }else{
        throw new ArgumentException("Not a valid serialization of a person");
    }
}

public string SerializeToString()
{
    return "#\n" +
           name + "\n" + 
           age;
}

Set the PATH variable, like you're doing. If you're running the program from the IDE, you can modify environment variables by adjusting the Debugging options in the project properties.

If the DLLs are named such that you don't need different paths for the different configuration types, you can add the path to the system PATH variable or to Visual Studio's global one in Tools | Options.

I think you want to make objects from array and combine it with an old object (BODY.recipients.values), if it's then you may do it using $.extent (because you are using jQuery/tagged) method after prepare the object from array

var BODY = {
    "recipients": {
        "values": []
    },
    "subject": 'TitleOfSubject',
    "body": 'This is the message body.'
}

var values = [],
names = ['sheikh', 'muhammed', 'Answer', 'Uddin', 'Heera']; // for testing
for (var ln = 0; ln < names.length; ln++) {
    var item1 = {
        "person": { "_path": "/people/"+names[ln] }
    };
    values.push(item1);
}

// Now merge with BODY
$.extend(BODY.recipients.values, values);

        return (IsRelative ? separator.ToString() : string.Empty) + final;
    }

It works for URLs as well as normal paths.

Usage:

    // Fixes internal paths
    Console.WriteLine(PathCombine(true , true , true , @"\/\/folder 1\/\/\/\\/\folder2\///folder3\\/" , @"/\somefile.ext\/\//\"));
    // Result: /folder 1/folder2/folder3/somefile.ext

    // Doesn't fix internal paths
    Console.WriteLine(PathCombine(true , true , false , @"\/\/folder 1\/\/\/\\/\folder2\///folder3\\/" , @"/\somefile.ext\/\//\"));
    //result : /folder 1//////////folder2////folder3/somefile.ext

    // Don't worry about URL prefixes when fixing internal paths
    Console.WriteLine(PathCombine(true , false , true , @"/\/\/https:/\/\/\lul.com\/\/\/\\/\folder2\///folder3\\/" , @"/\somefile.ext\/\//\"));
    // Result: https://lul.com/folder2/folder3/somefile.ext

    Console.WriteLine(PathCombine(false , true , true , @"../../../\\..\...\./../somepath" , @"anotherpath"));
    // Result: \..\..\..\..\...\.\..\somepath\anotherpath

There could be MULTIPLE POSSIBLE WAYS to check if an element(in your case its Object) is present in an array or not.

const arr = [
  { id: 1, username: 'fred' },
  { id: 2, username: 'bill' },
  { id: 3, username: 'ted' },
];

let say you want to find an object with id = 3.

1. find: It searches for an element in an array and if it finds out then it returns that element else return undefined. It returns the value of the first element in the provided array that satisfies the provided testing function. reference

const ObjIdToFind = 5;
const isObjectPresent = arr.find((o) => o.id === ObjIdToFind);
if (!isObjectPresent) {            // As find return object else undefined
  arr.push({ id: arr.length + 1, username: 'Lorem ipsum' });

2. filter: It searches for elements in an array and filters out all element that matches the condition. It returns a new array with all elements and if none matches the condition then an empty array. reference

const ObjIdToFind = 5;
const arrayWithFilterObjects= arr.filter((o) => o.id === ObjIdToFind);
if (!arrayWithFilterObjects.length) {       // As filter return new array
  arr.push({ id: arr.length + 1, username: 'Lorem ipsum' });
}

3. some: The some() method tests whether at least one element is present in an array that passes the test implemented by the provided function. It returns a Boolean value. reference

const ObjIdToFind = 5;
const isElementPresent = arr.some((o) => o.id === ObjIdToFind);
if (!isElementPresent) {                  // As some return Boolean value
  arr.push({ id: arr.length + 1, username: 'Lorem ipsum' });
}

Since coffee script has no var statement it automatically inserts it for all variables in the coffee-script, that way it prevents the compiled JavaScript version from leaking everything into the global namespace.

So since there's no way to make something "leak" into the global namespace from the coffee-script side of things on purpose, you need to define your global variables as properties of the global object.

attach them as properties on window

This means you need to do something like window.foo = 'baz';, which handles the browser case, since there the global object is the window.

Node.js

In Node.js there's no window object, instead there's the exports object that gets passed into the wrapper that wraps the Node.js module (See: https://github.com/ry/node/blob/master/src/node.js#L321 ), so in Node.js what you would need to do is exports.foo = 'baz';.

Now let us take a look at what it states in your quote from the docs:

...targeting both CommonJS and the browser: root = exports ? this

This is obviously coffee-script, so let's take a look into what this actually compiles to:

var root;
root = (typeof exports !== "undefined" && exports !== null) ? exports : this;

First it will check whether exports is defined, since trying to reference a non existent variable in JavaScript would otherwise yield an SyntaxError (except when it's used with typeof)

So if exports exists, which is the case in Node.js (or in a badly written WebSite...) root will point to exports, otherwise to this. So what's this?

(function() {...}).call(this);

Using .call on a function will bind the this inside the function to the first parameter passed, in case of the browser this would now be the window object, in case of Node.js it would be the global context which is also available as the global object.

But since you have the require function in Node.js, there's no need to assign something to the global object in Node.js, instead you assign to the exports object which then gets returned by the require function.

Coffee-Script

After all that explanation, here's what you need to do:

root = exports ? this
root.foo = -> 'Hello World'

This will declare our function foo in the global namespace (whatever that happens to be).
That's all :)

If you are using your EditText in Dialog or creating dynamically and You can't set it from xml then this example will help you in setting that type of key board while you are using dynamic Edit Text etc

myEditTxt.setInputType(InputType.TYPE_CLASS_NUMBER);

where myEditTxt is the dynamic EDIT TEXT object(name)

You can not drop the foreign key column because it is being referenced from the table assignmentStuff. So you should first drop the foreign key constraint assignmentStuff.assignmentIDX.

A similar question has already been asked here. Check also here for more info.

this will do the magic

    <script>
        document.addEventListener("DOMContentLoaded", function(event) { 
            var scrollpos = localStorage.getItem('scrollpos');
            if (scrollpos) window.scrollTo(0, scrollpos);
        });

        window.onbeforeunload = function(e) {
            localStorage.setItem('scrollpos', window.scrollY);
        };
    </script>

First hit of a search for perl @_ says this:

I would like to suggest to use react-native-vector-icons to import icons to your project. As you use vector icons, you don't need to worry much on icon scaling side. While using the package you are able to use all popular icon set such as fontawesome, ionicons etc..

Besides these iconsets you can also bring your own icons too to your react-native project by packing your icons as a ttf file and you can import that ttf directly to both android and ios project. You can utilise the same react-native-vector-icons library to manage those icons

Here is a detailed procedure to setup custom icons

Using the php cURL libraries will probably be the right way to go, as this library has more features than the simple file_get_contents(...).

An example:

<?php
$ch = curl_init();
$headers = array('HTTP_ACCEPT: Something', 'HTTP_ACCEPT_LANGUAGE: fr, en, da, nl', 'HTTP_CONNECTION: Something');

curl_setopt($ch, CURLOPT_URL, "http://localhost"); # URL to post to
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1 ); # return into a variable
curl_setopt($ch, CURLOPT_HTTPHEADER, $header ); # custom headers, see above
$result = curl_exec( $ch ); # run!
curl_close($ch);
?>

Iteration is synonymous with sprint, sprint is just the Scrum terminology.

On the question about sprint length, the only caution I would note is that in Scrum you are using the past sprints to gain a level of predictability on your teams ability to deliver on their commitments for the sprint. They do this by developing a velocity over a number of sprints. A change in the team members or the length of the sprint are factors that will affect the velocity for a sprint, over past sprints.

Just as background, velocity is the sum of estimation points assigned to the backlog items, or stories, that were completely finished during that sprint. Most Agile proponents (Mike Cohn, Ken Schwaber and Jeff Sutherland for instance), recommend that teams use "the recent weather" to base their future estimations on how much they think they can commit to in a sprint. This means using the average from the last few sprints as the basis for an estimate in the upcoming sprint planning session.

Once again, varying the sprint length reduces your teams ability to provide that velocity statistic which the team uses for sprint planning, and the product owner uses for release planning (i.e. predicting when the project will end or what will be in the project at the end).

I recommend Mike Cohn's book on Agile Estimating and Planning to provide an overview of the way sprints, estimation and planning all can fit together.

try this one :

public void itemClicked(View v) {
  //code to check if this checkbox is checked!
  CheckBox checkBox = (CheckBox)v;
  if(checkBox.isChecked()){

  }
}

To test and try curl requests from Windows, you can make use of Postman client Chrome extension. It is very simple to use and quite powerful.

Or as suggested you can install the cURL util.

A sample curl request is as follows.

curl -X POST -H "Content-Type: application/json" -H "Cache-Control: no-cache" -d '{
"user" : "Arun Thundyill Saseendran",
"post_date" : "2009-03-23T12:30:00",
"message" : "trying out Elasticsearch"
}' "http://10.103.102.56:9200/sampleindex/sampletype/"

I am also getting started with and exploring ES in vast. So please let me know if you have any other doubts.

EDIT: Updated the index name and type name to be fully lowercase to avoid errors and follow convention.

For some reason IntelliJ (at least in version 2019.1.2) ignores dependencies in local .m2 directory. None of above solutions worked for me. The only thing finally forced IntelliJ to discover local dependencies was:

1. Close project
2. Open project clicking on pom.xml (not on a project directory)
3. Click Open as Project

4. Click Delete Existing Project and Import

The short answer: the setting needs to be setup when the connection to the MySQL server is established. For example, if using MYSQLi / PHP, it will look something like this:

$ myConn = mysqli_init(); 
$ myConn->options(MYSQLI_INIT_COMMAND, 'SET SESSION group_concat_max_len = 1000000');

Therefore, if you are using a home-brewed framework, well, you need to look for the place in the code when the connection is establish and provide a sensible value.

I am still using Codeigniter 3 on 2020, so in this framework, the code to add is in the application/system/database/drivers/mysqli/mysqli_driver.php, the function is named db_connect();

public function db_connect($persistent = FALSE)
    {
        // Do we have a socket path?
        if ($this->hostname[0] === '/')
        {
            $hostname = NULL;
            $port = NULL;
            $socket = $this->hostname;
        }
        else
        {
            $hostname = ($persistent === TRUE)
                ? 'p:'.$this->hostname : $this->hostname;
            $port = empty($this->port) ? NULL : $this->port;
            $socket = NULL;
        }

        $client_flags = ($this->compress === TRUE) ? MYSQLI_CLIENT_COMPRESS : 0;
        $this->_mysqli = mysqli_init();

        $this->_mysqli->options(MYSQLI_OPT_CONNECT_TIMEOUT, 10);
        $this->_mysqli->options(MYSQLI_INIT_COMMAND, 'SET SESSION group_concat_max_len = 1000000');

...
    }

You can use the IsNewSession property to check if the session was created on the request of the page

protected void Page_Load() 
{ 
   if (Context.Session != null) 
   { 
      if (Session.IsNewSession) 
      { 
         string cookieHeader = Request.Headers["Cookie"]; 
         if ((null != cookieHeader) && (cookieHeader.IndexOf("ASP.NET_SessionId") >= 0)) 
         { 
            Response.Redirect("sessionTimeout.htm"); 
         } 
      } 
   } 
}

Store Userid in session variable when user logs into website and check on your master page or created base page form which other page gets inherits. Then in page load check that Userid is present and not if not then redirect to login page.

if(Session["Userid"]==null)
{
  //session expire redirect to login page 
}

Give Xml Visualizer a try. Haven't tried the latest version yet, but I can't work without the previous one in Visual Studio 2003.

on top of displaying DataSet hierarchically, there are also a lot of other handy features such as filtering and selecting the RowState which you want to view.

I had the same problem. So here is the real answer: Mount the system under /proc. Here is my command:

mount -o rw,remount /proc /system

It works, and in fact is the only way I can overcome the Read-only System problem.

Math.Round(0.5) returns zero due to floating point rounding errors, so you'll need to add a rounding error amount to the original value to ensure it doesn't round down, eg.

Console.WriteLine(Math.Round(0.5, 0).ToString()); // outputs 0 (!!)
Console.WriteLine(Math.Round(1.5, 0).ToString()); // outputs 2
Console.WriteLine(Math.Round(0.5 + 0.00000001, 0).ToString()); // outputs 1
Console.WriteLine(Math.Round(1.5 + 0.00000001, 0).ToString()); // outputs 2
Console.ReadKey();

The most contextual description of JavaScript's Automatic Semicolon Insertion I have found comes from a book about Crafting Interpreters.

JavaScript’s “automatic semicolon insertion” rule is the odd one. Where other languages assume most newlines are meaningful and only a few should be ignored in multi-line statements, JS assumes the opposite. It treats all of your newlines as meaningless whitespace unless it encounters a parse error. If it does, it goes back and tries turning the previous newline into a semicolon to get something grammatically valid.

He goes on to describe it as you would code smell.

This design note would turn into a design diatribe if I went into complete detail about how that even works, much less all the various ways that that is a bad idea. It’s a mess. JavaScript is the only language I know where many style guides demand explicit semicolons after every statement even though the language theoretically lets you elide them.

Casting is necessary to tell that you are calling a child and not a parent method. So it's ever downward. However if the method is already defined in the parent class and overriden in the child class, you don't any cast. Here an example:

class Parent{
   void method(){ System.out.print("this is the parent"); }
}

class Child extends Parent{
   @override
   void method(){ System.out.print("this is the child"); }
}
...
Parent o = new Child();
o.method();
((Child)o).method();  

The two method call will both print : "this is the child".

string keyName=@"HKEY_LOCAL_MACHINE\System\CurrentControlSet\services\pcmcia";
string valueName="Start";
if (Registry.GetValue(keyName, valueName, null) == null)
{
     //code if key Not Exist
}
else
{
     //code if key Exist
}

"break" is a command that breaks out of the "closest" loop.

While there are many good uses for break, you shouldn't use it if you don't have to -- it can be seen as just another way to use goto, which is considered bad.

For example, why not:

while (!(the condition you're using to break))
        {
         //Your code here.
        }

If the reason you're using "break" is because you don't want to continue execution of that iteration of the loop, you may want to use the "continue" keyword, which immediately jumps to the next iteration of the loop, whether it be while or for.

while (!condition) {
   //Some code
   if (condition) continue;
   //More code that will be skipped over if the condition was true
}

There are 2 calls that need to set the correct headers. Initially there is a preflight check so you need something like...

app.get('/item', item.list);
app.options('/item', item.preflight);

and then have the following functions...

exports.list = function (req, res) {
Items.allItems(function (err, items) {
    ...
        res.header('Access-Control-Allow-Origin', "*");     // TODO - Make this more secure!!
        res.header('Access-Control-Allow-Methods', 'GET,PUT,POST');
        res.header('Access-Control-Allow-Headers', 'Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept');
        res.send(items);
      }
   );
};

and for the pre-flight checks

exports.preflight = function (req, res) {
Items.allItems(function (err, items) {
        res.header('Access-Control-Allow-Origin', "*");     // TODO - Make this more secure!!
        res.header('Access-Control-Allow-Methods', 'GET,PUT,POST');
        res.header('Access-Control-Allow-Headers', 'Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept');
        res.send(200);
    }
  );
};

You can consolidate the res.header() code into a single function if you want.

Also as stated above, be careful of using res.header('Access-Control-Allow-Origin', "*") this means anyone can access your site!

Another way of dealing with this situation if your files ARE already checked in, and your files have been merged (but not committed, so the merge conflicts are inserted into the file) is to run:

git reset

This will switch to HEAD, and tell git to forget any merge conflicts, and leave the working directory as is. Then you can edit the files in question (search for the "Updated upstream" notices). Once you've dealt with the conflicts, you can run

git add -p

which will allow you to interactively select which changes you want to add to the index. Once the index looks good (git diff --cached), you can commit, and then

git reset --hard

to destroy all the unwanted changes in your working directory.

The way to do this is to run the following command:

bundle update --source gem-name

JavaScript uses the \ (backslash) as an escape characters for:

• \' single quote
• \" double quote
• \ backslash
• \n new line
• \r carriage return
• \t tab
• \b backspace
• \f form feed
• \v vertical tab (IE < 9 treats '\v' as 'v' instead of a vertical tab ('\x0B'). If cross-browser compatibility is a concern, use \x0B instead of \v.)
• \0 null character (U+0000 NULL) (only if the next character is not a decimal digit; else it’s an octal escape sequence)

Note that the \v and \0 escapes are not allowed in JSON strings.

var prettyDate = $.datepicker.formatDate('dd-M-yy', new Date());
alert(prettyDate);

Assign the prettyDate to the necessary control.

Add { } while importing and exporting: export { ... }; | import { ... } from './Template';

export → import { ... } from './Template'

export default → import ... from './Template'

Here is a working example:

// ExportExample.js
import React from "react";

function DefaultExport() {
  return "This is the default export";
}

function Export1() {
  return "Export without default 1";
}

function Export2() {
  return "Export without default 2";
}

export default DefaultExport;
export { Export1, Export2 };

// App.js
import React from "react";
import DefaultExport, { Export1, Export2 } from "./ExportExample";

export default function App() {
  return (
    <>
      <strong>
        <DefaultExport />
      </strong>
      <br />
      <Export1 />
      <br />
      <Export2 />
    </>
  );
}

Note the comma between the zero and the "K". To display millions or billions, use two or three commas instead.

Basically, all Maven is telling you is that certain dependencies in your project are not available in the central maven repository. The default is to look in your local .m2 folder (local repository), and then any configured repositories in your POM, and then the central maven repository. Look at the repositories section of the Maven reference.

The problem is that the project that was checked in didn't configure the POM in such a way that all the dependencies could be found and the project could be built from scratch.

In the earlier answers weight is passed to the constructor of a new SomeLayoutType.LayoutParams object. Still in many cases it's more convenient to use existing objects - it helps to avoid dealing with parameters we are not interested in.

An example:

// Get our View (TextView or anything) object:
View v = findViewById(R.id.our_view); 

// Get params:
LinearLayout.LayoutParams loparams = (LinearLayout.LayoutParams) v.getLayoutParams();

// Set only target params:
loparams.height = 0;
loparams.weight = 1;
v.setLayoutParams(loparams);

As a shorthand you can run:

docker tag d58 myname/server:latest

Where d58 represents the first 3 characters of the IMAGE ID,in this case, that's all you need.

Finally, you can remove the old image as follows:

docker rmi server

Make sure your jquery is inside $(document).ready function or similar.

Also you can improve your code by using jquery data

I know this is a very old question, but I've been asked by someone else something similar.

I don't have TeraData, but can't you do the following?

SELECT employee_number,
       course_code,
       MAX(course_completion_date)                                     AS max_course_date,
       MAX(course_completion_date) OVER (PARTITION BY employee_number) AS max_date
FROM employee_course_completion
WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
GROUP BY employee_number, course_code

The GROUP BY now ensures one row per course per employee. This means that you just need a straight MAX() to get the max_course_date.

Before your GROUP BY was just giving one row per employee, and the MAX() OVER() was trying to give multiple results for that one row (one per course).

Instead, you now need the OVER() clause to get the MAX() for the employee as a whole. This is now legitimate because each individual row gets just one answer (as it is derived from a super-set, not a sub-set). Also, for the same reason, the OVER() clause now refers to a valid scalar value, as defined by the GROUP BY clause; employee_number.

Perhaps a short way of saying this would be that an aggregate with an OVER() clause must be a super-set of the GROUP BY, not a sub-set.

Create your query with a GROUP BY at the level that represents the rows you want, then specify OVER() clauses if you want to aggregate at a higher level.

string _connString = "metadata=res://*/Model.csdl|res://*/Model.ssdl|res://*/Model.msl;provider=System.Data.SqlClient;provider connection string="data source=localhost;initial catalog=DATABASE;persist security info=True;user id=sa;password=YourPassword;multipleactiveresultsets=True;App=EntityFramework"";

EntityConnectionStringBuilder ecsb = new EntityConnectionStringBuilder(_connString);
ctx = new Entities(_connString);

You can get the connection string from the web.config, and just set that in the EntityConnectionStringBuilder constructor, and use the EntityConnectionStringBuilder as an argument in the constructor for the context.

Cache the connection string by username. Simple example using a couple of generic methods to handle adding/retrieving from cache.

private static readonly ObjectCache cache = MemoryCache.Default;

// add to cache
AddToCache<string>(username, value);

// get from cache

 string value = GetFromCache<string>(username);
 if (value != null)
 {
     // got item, do something with it.
 }
 else
 {
    // item does not exist in cache.
 }


public void AddToCache<T>(string token, T item)
    {
        cache.Add(token, item, DateTime.Now.AddMinutes(1));
    }

public T GetFromCache<T>(string cacheKey) where T : class
    {
        try
        {
            return (T)cache[cacheKey];
        }
        catch
        {
            return null;
        }
    }

Change the Foreign key name in MySQL. You can not have the same foreign key names in the database tables.

Check all your tables and all your foreign keys and avoid having two foreign keys with the same exact name.

AJAX is a technique to do an XMLHttpRequest (out of band Http request) from a web page to the server and send/retrieve data to be used on the web page. AJAX stands for Asynchronous Javascript And XML. It uses javascript to construct an XMLHttpRequest, typically using different techniques on various browsers.

jQuery (website) is a javascript framework that makes working with the DOM easier by building lots of high level functionality that can be used to search and interact with the DOM. Part of the functionality of jQuery implements a high-level interface to do AJAX requests. jQuery implements this interface abstractly, shielding the developer from the complexity of multi-browser support in making the request.

I've got through DLL hell like this before. My final solution was to store the unmanaged DLLs in the managed DLL as binary resources, and extract them to a temporary folder when the program launches and delete them when it gets disposed.

This should be part of the .NET or pinvoke infrastructure, since it is so useful.... It makes your managed DLL easy to manage, both using Xcopy or as a Project reference in a bigger Visual Studio solution. Once you do this, you don't have to worry about post-build events.

UPDATE:

I posted code here in another answer https://stackoverflow.com/a/11038376/364818

for loop will be iterate through index..

consider you have a list,

[5, 7, 13, 29, 65, 91]

you have using list variable called lis. and you using same to remove..

your variable

lis = [5, 7, 13, 29, 35, 65, 91]
       0  1   2   3   4   5   6

during 5th iteration,

your number 35 was not a prime so you removed it from a list.

lis.remove(y)

and then next value (65) move on to previous index.

lis = [5, 7, 13, 29, 65, 91]
       0  1   2   3   4   5

so 4th iteration done pointer moved onto 5th..

thats why your loop doesnt cover 65 since its moved into previous index.

so you shouldn't reference list into another variable which still reference original instead of copy.

ite = lis #dont do it will reference instead copy

so do copy of list using list[::]

now you it will give,

[5, 7, 13, 29]

Problem is you removed a value from a list during iteration then your list index will collapse.

so you can try comprehension instead.

which supports all the iterable like, list, tuple, dict, string etc

Heres some code in c to convert rgb to grayscale. The real weighting used for rgb to grayscale conversion is 0.3R+0.6G+0.11B. these weights arent absolutely critical so you can play with them. I have made them 0.25R+ 0.5G+0.25B. It produces a slightly darker image.

NOTE: The following code assumes xRGB 32bit pixel format

unsigned int *pntrBWImage=(unsigned int*)..data pointer..;  //assumes 4*width*height bytes with 32 bits i.e. 4 bytes per pixel
unsigned int fourBytes;
        unsigned char r,g,b;
        for (int index=0;index<width*height;index++)
        {
            fourBytes=pntrBWImage[index];//caches 4 bytes at a time
            r=(fourBytes>>16);
            g=(fourBytes>>8);
            b=fourBytes;

            I_Out[index] = (r >>2)+ (g>>1) + (b>>2); //This runs in 0.00065s on my pc and produces slightly darker results
            //I_Out[index]=((unsigned int)(r+g+b))/3;     //This runs in 0.0011s on my pc and produces a pure average

Extension to ollyc recipe :

CREATE VIEW foreign_keys_view AS
SELECT
    tc.table_name, kcu.column_name,
    ccu.table_name AS foreign_table_name,
    ccu.column_name AS foreign_column_name
FROM
    information_schema.table_constraints AS tc

You can use some online websites to beautify JSON, such as: JSON Formatter, and then paste the beautified result to WIKI

SQL Server was not configured to allow mixed authentication.

Here are steps to fix:

1. Right-click on SQL Server instance at root of Object Explorer, click on Properties
2. Select Security from the left pane.

3. Select the SQL Server and Windows Authentication mode radio button, and click OK.

   

4. Right-click on the SQL Server instance, select Restart (alternatively, open up Services and restart the SQL Server service).

This is also incredibly helpful for IBM Connections users, my wizards were not able to connect until I fxed this setting.

There is often the tip to use 'echo.'

But that is slow, and it could fail with an error message, as cmd.exe will search first for a file named 'echo' (without extension) and only when the file doesn't exists it outputs an empty line.

You could use echo(. This is approximately 20 times faster, and it works always. The only drawback could be that it looks odd.

More about the different ECHO:/\ variants is at DOS tips: ECHO. FAILS to give text or blank line.

I settled on a more general-purpose solution that allows concatenating an arbitrary set of one-dimensional arrays of the same type. (I was concatenating 3+ at a time.)

My function:

    public static T[] ConcatArrays<T>(params T[][] list)
    {
        var result = new T[list.Sum(a => a.Length)];
        int offset = 0;
        for (int x = 0; x < list.Length; x++)
        {
            list[x].CopyTo(result, offset);
            offset += list[x].Length;
        }
        return result;
    }

And usage:

        int[] a = new int[] { 1, 2, 3 };
        int[] b = new int[] { 4, 5, 6 };
        int[] c = new int[] { 7, 8 };
        var y = ConcatArrays(a, b, c); //Results in int[] {1,2,3,4,5,6,7,8}

If you use Grunt to build your project, there is a plugin that will automatically assemble your partials into an Angular module that primes $templateCache. You can concatenate this module with the rest of your code and load everything from one file on startup.

https://npmjs.org/package/grunt-html2js

Try this:

import os
import sys

for root, subdirs, files in os.walk(path):

    for file in os.listdir(root):

        filePath = os.path.join(root, file)

        if os.path.isdir(filePath):
            pass

        else:
            f = open (filePath, 'r')
            # Do Stuff

You can use LinkedBlockingQueue I use it in my projects. It's part of standard java and quite easy to use

There is an in-built stopword list in NLTK made up of 2,400 stopwords for 11 languages (Porter et al), see http://nltk.org/book/ch02.html

>>> from nltk import word_tokenize
>>> from nltk.corpus import stopwords
>>> stop = set(stopwords.words('english'))
>>> sentence = "this is a foo bar sentence"
>>> print([i for i in sentence.lower().split() if i not in stop])
['foo', 'bar', 'sentence']
>>> [i for i in word_tokenize(sentence.lower()) if i not in stop] 
['foo', 'bar', 'sentence']

I recommend looking at using tf-idf to remove stopwords, see Effects of Stemming on the term frequency?

In case you are working with a column with string values, you can use THE VERY USEFUL function series.str.isnumeric() like:

a = pd.Series(['hi','hola','2.31','288','312','1312', '0,21', '0.23'])

What i do is to copy that column to new column, and do a str.replace('.','') and str.replace(',','') then i select the numeric values. and:

a = a.str.replace('.','')
a = a.str.replace(',','') 
a.str.isnumeric()

Out[15]: 0 False 1 False 2 True 3 True 4 True 5 True 6 True 7 True dtype: bool

Good luck all!

Or for what seems like rampant overkill, but is actually simplistic ... Pretty much covers all of your cases, and no empty string or unary concerns.

In the case the first arg is '-v', then do your conditional ps -ef, else in all other cases throw the usage.

#!/bin/sh
case $1 in
  '-v') if [ "$1" = -v ]; then
         echo "`ps -ef | grep -v '\['`"
        else
         echo "`ps -ef | grep '\[' | grep root`"
        fi;;
     *) echo "usage: $0 [-v]"
        exit 1;; #It is good practice to throw a code, hence allowing $? check
esac

If one cares not where the '-v' arg is, then simply drop the case inside a loop. The would allow walking all the args and finding '-v' anywhere (provided it exists). This means command line argument order is not important. Be forewarned, as presented, the variable arg_match is set, thus it is merely a flag. It allows for multiple occurrences of the '-v' arg. One could ignore all other occurrences of '-v' easy enough.

#!/bin/sh

usage ()
 {
  echo "usage: $0 [-v]"
  exit 1
 }

unset arg_match

for arg in $*
 do
  case $arg in
    '-v') if [ "$arg" = -v ]; then
           echo "`ps -ef | grep -v '\['`"
          else
           echo "`ps -ef | grep '\[' | grep root`"
          fi
          arg_match=1;; # this is set, but could increment.
       *) ;;
  esac
done

if [ ! $arg_match ]
 then
  usage
fi

But, allow multiple occurrences of an argument is convenient to use in situations such as:

$ adduser -u:sam -s -f -u:bob -trace -verbose

We care not about the order of the arguments, and even allow multiple -u arguments. Yes, it is a simple matter to also allow:

$ adduser -u sam -s -f -u bob -trace -verbose

As many other pointed out, Intel HAXM only supports Intel CPUs. Since Windows 1804 you can use Microsoft's Hyper-V instead of HAXM for the emulator. This also helps people who want to use Hyper-V for virtual machines as you need to disable hyper-v to run haxm.

Short version:

• install Windows Hypervisor Platform feature
• Update to Android Emulator 27.2.7 or above
• put WindowsHypervisorPlatform = on into C:\Users\your-username\.android\advancedFeatures.ini or start emulator or command line with -feature WindowsHypervisorPlatform
• enable IOMMU in your BIOS settings

According to Dangerously Set innerHTML,

Improper use of the innerHTML can open you up to a cross-site scripting (XSS) attack. Sanitizing user input for display is notoriously error-prone, and failure to properly sanitize is one of the leading causes of web vulnerabilities on the internet.

Our design philosophy is that it should be "easy" to make things safe, and developers should explicitly state their intent when performing “unsafe” operations. The prop name dangerouslySetInnerHTML is intentionally chosen to be frightening, and the prop value (an object instead of a string) can be used to indicate sanitized data.

After fully understanding the security ramifications and properly sanitizing the data, create a new object containing only the key __html and your sanitized data as the value. Here is an example using the JSX syntax:

function createMarkup() {
    return {
       __html: 'First · Second'    };
 }; 

<div dangerouslySetInnerHTML={createMarkup()} /> 

Read more about it using below link:

documentation: React DOM Elements - dangerouslySetInnerHTML.

I recommend reading through the Sun's tutorials for code examples and practice in all areas of Java programming, especially the areas you wish to improve in.

Depending on how much of beginner examples you were looking for, check out CodingBat for some good beginner exercises. Project Euler is another good site, but depending on your skill level now, this may be too much, but it's worth trying anyways.

Most importantly, Its also worth noting that personal projects are a great way to start to learn a new language. I would also recommend starting a project that is benefical to you and get cracking right away, no time is better than the present!

Refer to example 2 for 'Type' class understanding of Gson.

Example 1: In this deserilizeResturant we used Employee[] array and get the details

public static void deserializeResturant(){

       String empList ="[{\"name\":\"Ram\",\"empId\":1},{\"name\":\"Surya\",\"empId\":2},{\"name\":\"Prasants\",\"empId\":3}]";
       Gson gson = new Gson();
       Employee[] emp = gson.fromJson(empList, Employee[].class);
       int numberOfElementInJson = emp.length();
       System.out.println("Total JSON Elements" + numberOfElementInJson);
       for(Employee e: emp){
           System.out.println(e.getName());
           System.out.println(e.getEmpId());
       }
   }

Example 2:

//Above deserilizeResturant used Employee[] array but what if we need to use List<Employee>
public static void deserializeResturantUsingList(){

    String empList ="[{\"name\":\"Ram\",\"empId\":1},{\"name\":\"Surya\",\"empId\":2},{\"name\":\"Prasants\",\"empId\":3}]";
    Gson gson = new Gson();

    // Additionally we need to se the Type then only it accepts List<Employee> which we sent here empTypeList
    Type empTypeList = new TypeToken<ArrayList<Employee>>(){}.getType();


    List<Employee> emp = gson.fromJson(empList, empTypeList);
    int numberOfElementInJson = emp.size();
    System.out.println("Total JSON Elements" + numberOfElementInJson);
    for(Employee e: emp){
        System.out.println(e.getName());
        System.out.println(e.getEmpId());
    }
}

Interesting blog post here:

http://geekswithblogs.net/cskardon/archive/2008/06/23/dispose-of-a-wpf-usercontrol-ish.aspx

It mentions subscribing to Dispatcher.ShutdownStarted to dispose of your resources.

You can do this...

var string = 'This is\n' +
'a multiline\n' + 
'string';

you can use the new HTML 5 file api to read file contents

https://developer.mozilla.org/en-US/docs/Using_files_from_web_applications

but this won't work on every browser so you probably need a server side fallback.

To install scipy on windows follow these instructions:-

Step-1 : Press this link http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy to download a scipy .whl file (e.g. scipy-0.17.0-cp34-none-win_amd64.whl).

Step-2: Go to the directory where that download file is there from the command prompt (cd folder-name ).

Step-3: Run this command:

pip install scipy-0.17.0-cp27-none-win_amd64.whl

In addition to the still very relevant answer of jujule, I find it quite important to also be aware of the implications of order_by() on distinct("field_name") queries. This is, however, a Postgres only feature!

If you are using Postgres and if you define a field name that the query should be distinct for, then order_by() needs to begin with the same field name (or field names) in the same sequence (there may be more fields afterward).

Note

When you specify field names, you must provide an order_by() in the QuerySet, and the fields in order_by() must start with the fields in distinct(), in the same order.

For example, SELECT DISTINCT ON (a) gives you the first row for each value in column a. If you don’t specify an order, you’ll get some arbitrary row.

If you want to e-g- extract a list of cities that you know shops in , the example of jujule would have to be adapted to this:

# returns an iterable Queryset of cities.
models.Shop.objects.order_by('city').values_list('city', flat=True).distinct('city')  

This should do the work:

.category_table tr:first-child td {
    vertical-align: top;
}

Here's a solution with flexbox for images with variable width and height:

.container {
  display: flex;
  flex-wrap: no-wrap;
  overflow-x: auto;
  margin: 20px;
}
img {
  flex: 0 0 auto;
  width: auto;
  height: 100px;
  max-width: 100%;
  margin-right: 10px;
}

It will work..

requests does not handle parsing XML responses, no. XML responses are much more complex in nature than JSON responses, how you'd serialize XML data into Python structures is not nearly as straightforward.

Python comes with built-in XML parsers. I recommend you use the ElementTree API:

import requests
from xml.etree import ElementTree

response = requests.get(url)

tree = ElementTree.fromstring(response.content)

or, if the response is particularly large, use an incremental approach:

    response = requests.get(url, stream=True)
    # if the server sent a Gzip or Deflate compressed response, decompress
    # as we read the raw stream:
    response.raw.decode_content = True

    events = ElementTree.iterparse(response.raw)
    for event, elem in events:
        # do something with `elem`

The external lxml project builds on the same API to give you more features and power still.

Before you use DecimalFormat you need to use the following import or your code will not work:

import java.text.DecimalFormat;

The code for formatting is:

DecimalFormat precision = new DecimalFormat("0.00"); 
// dblVariable is a number variable and not a String in this case
txtTextField.setText(precision.format(dblVariable));

from math import ceil

num = 0.1111111111000
num = ceil(num * 100) / 100.0

See:
math.ceil documentation
round documentation - You'll probably want to check this out anyway for future reference

Try this:

<div onselectstart="return false">some stuff</div>

Simple, but effective... works in current versions of all major browsers.

Use:

if (containerObject.has("video")) {
    //get value of video
}

Put

compile 'com.google.zxing:core:2.3.0' 

into your Gradle dependencies. As easy as that. Prior to using Android Studio and Gradle build system.

New Way (Recommended):

Please take a look at this answer.

Old Way:

Supposing you're writing a program called myprog :

Put all your files in a directory like this

myproject/go/src/myprog/xxx.go

Then add myproject/go to GOPATH

And run

go install myprog

This way you'll be able to add other packages and programs in myproject/go/src if you want.

(this doc is always missed by newcomers, and often ill-understood at first. It should receive the greatest attention of the Go team IMO)

The party's pretty much dead now, but here's an "improved" version of user166390 that made its way into my extension library. Apart from some details, I added a delegate to calculate the merged value.

/// <summary>
/// Merges a dictionary against an array of other dictionaries.
/// </summary>
/// <typeparam name="TResult">The type of the resulting dictionary.</typeparam>
/// <typeparam name="TKey">The type of the key in the resulting dictionary.</typeparam>
/// <typeparam name="TValue">The type of the value in the resulting dictionary.</typeparam>
/// <param name="source">The source dictionary.</param>
/// <param name="mergeBehavior">A delegate returning the merged value. (Parameters in order: The current key, The current value, The previous value)</param>
/// <param name="mergers">Dictionaries to merge against.</param>
/// <returns>The merged dictionary.</returns>
public static TResult MergeLeft<TResult, TKey, TValue>(
    this TResult source,
    Func<TKey, TValue, TValue, TValue> mergeBehavior,
    params IDictionary<TKey, TValue>[] mergers)
    where TResult : IDictionary<TKey, TValue>, new()
{
    var result = new TResult();
    var sources = new List<IDictionary<TKey, TValue>> { source }
        .Concat(mergers);

    foreach (var kv in sources.SelectMany(src => src))
    {
        TValue previousValue;
        result.TryGetValue(kv.Key, out previousValue);
        result[kv.Key] = mergeBehavior(kv.Key, kv.Value, previousValue);
    }

    return result;
}

df = df.loc[:, ~df.columns.str.contains('^Unnamed')]

In [162]: df
Out[162]:
   colA  ColB  colC  colD  colE  colF  colG
0    44    45    26    26    40    26    46

4    39    47    16    42    33    48    38

if the first column in the CSV file has index values, then you can do this instead:

df = pd.read_csv('data.csv', index_col=0)

From what I remember you could use VMRuntime class in early Android versions but now you just can't anymore.

I don't think letting the developer choose the heap size in a mobile environment can be considered so safe though. I think it's easier that you can find a way to modify the heap size in a specific device (not on the programming side) that by trying to modify it from the application itself.
