As APC rightly pointed out, your start_date column appears to be a TIMESTAMP but it could be a TIMESTAMP WITH LOCAL TIMEZONE or TIMESTAMP WITH TIMEZONE datatype too. These could well influence any queries you were doing on the data if your database server was in a different timezone to yourself. However, let's keep this simple and assume you are in the same timezone as your server. First, to give you the confidence, check that the start_date is a TIMESTAMP data type.

Use the SQLPlus DESCRIBE command (or the equivalent in your IDE) to verify this column is a TIMESTAMP data type.

eg

DESCRIBE mytable

Should report :

Name        Null? Type
----------- ----- ------------
NAME              VARHAR2(20) 
START_DATE        TIMESTAMP

If it is reported as a Type = TIMESTAMP then you can query your date ranges with simplest TO_TIMESTAMP date conversion, one which requires no argument (or picture).

We use TO_TIMESTAMP to ensure that any index on the START_DATE column is considered by the optimizer. APC's answer also noted that a function based index could have been created on this column and that would influence the SQL predicate but we cannot comment on that in this query. If you want to know how to find out what indexes have been applied to table, post another question and we can answer that separately.

So, assuming there is an index on start_date, which is a TIMESTAMP datatype and you want the optimizer to consider it, your SQL would be :

select * from mytable where start_date between to_timestamp('15-JAN-10') AND to_timestamp('17-JAN-10')+.9999999

+.999999999 is very close to but isn't quite 1 so the conversion of 17-JAN-10 will be as close to midnight on that day as possible, therefore you query returns both rows.

The database will see the BETWEEN as from 15-JAN-10 00:00:00:0000000 to 17-JAN-10 23:59:59:99999 and will therefore include all dates from 15th,16th and 17th Jan 2010 whatever the time component of the timestamp.

Hope that helps.

Vanilla R has a naive difftime class, but the Lubridate CRAN package lets you do what you ask:

require(lubridate)
d <- ymd(as.Date('2004-01-01')) %m+% months(1)
d
[1] "2004-02-01"

Hope that helps.

try the following

{
        Date dt2 = new DateAndTime().getCurrentDateTime();

        long diff = dt2.getTime() - dt1.getTime();
        long diffSeconds = diff / 1000 % 60;
        long diffMinutes = diff / (60 * 1000) % 60;
        long diffHours = diff / (60 * 60 * 1000);
        int diffInDays = (int) ((dt2.getTime() - dt1.getTime()) / (1000 * 60 * 60 * 24));

        if (diffInDays > 1) {
            System.err.println("Difference in number of days (2) : " + diffInDays);
            return false;
        } else if (diffHours > 24) {

            System.err.println(">24");
            return false;
        } else if ((diffHours == 24) && (diffMinutes >= 1)) {
            System.err.println("minutes");
            return false;
        }
        return true;
}

This depends on how you want the # of months to be defined. Answer this questions: 'What is difference in months: Feb 15, 2008 - Mar 12, 2009'. Is it defined by clear cut # of days which depends on leap years- what month it is, or same day of previous month = 1 month.

A calculation for Days:

Feb 15 -> 29 (leap year) = 14 Mar 1, 2008 + 365 = Mar 1, 2009. Mar 1 -> Mar 12 = 12 days. 14 + 365 + 12 = 391 days. Total = 391 days / (avg days in month = 30) = 13.03333

A calculation of months:

Feb 15 2008 - Feb 15 2009 = 12 Feb 15 -> Mar 12 = less than 1 month Total = 12 months, or 13 if feb 15 - mar 12 is considered 'the past month'

you should divide hours by 24 not 11
like this:
select to_char(sysdate - 2/24, 'dd-mon-yyyy HH24') from dual

Since you are using an INNER JOIN you can just put the conditions in the WHERE clause, like this:

SELECT 
    p1.kArtikel, 
    p1.cName, 
    p1.cKurzBeschreibung, 
    p1.dLetzteAktualisierung, 
    p1.dErstellt, 
    p1.cSeo,
    p2.kartikelpict,
    p2.nNr,
    p2.cPfad  
FROM 
    tartikel AS p1 INNER JOIN tartikelpict AS p2 
    ON p1.kArtikel = p2.kArtikel
WHERE
  DATE(dErstellt) > (NOW() - INTERVAL 7 DAY)
  AND p2.nNr = 1
ORDER BY 
  p1.kArtikel DESC
LIMIT
    100;

declare
strTime1 varchar2(50) := '02/08/2013 01:09:42 PM';
strTime2 varchar2(50) := '02/08/2013 11:09:00 PM';
v_date1 date := to_date(strTime1,'DD/MM/YYYY HH:MI:SS PM');
v_date2 date := to_date(strTime2,'DD/MM/YYYY HH:MI:SS PM');
difrence_In_Hours number;
difrence_In_minutes number;
difrence_In_seconds number;
begin
    difrence_In_Hours   := (v_date2 - v_date1) * 24;
    difrence_In_minutes := difrence_In_Hours * 60;
    difrence_In_seconds := difrence_In_minutes * 60;

    dbms_output.put_line(strTime1);        
    dbms_output.put_line(strTime2);
    dbms_output.put_line('*******');
    dbms_output.put_line('difrence_In_Hours  : ' || difrence_In_Hours);
    dbms_output.put_line('difrence_In_minutes: ' || difrence_In_minutes);
    dbms_output.put_line('difrence_In_seconds: ' || difrence_In_seconds);        
end ;

Hope this helps.

You could also set between two dates:

Delete From tblAudit
WHERE Date_dat < DATEADD(day, -360, GETDATE())
GO
Delete From tblAudit
WHERE Date_dat > DATEADD(day, -60, GETDATE())
GO

You can use the function TIME(h,m,s) of google spreadsheet. If you want to add times to each other (or other arithmetic operations), you can specify either a cell, or a call to TIME, for each input of the formula.

For example:

• B3 = 10:45
• C3 = 20 (minutes)
• D3 = 15 (minutes)
• E3 = 8 (hours)
• F3 = B3+time(E3,C3+D3,0) equals 19:20

I don't really understand why you would make this an HTML Helper. I would make it part of the ViewData dictionary in an action method of the controller. Something like this:

ViewData["Age"] = DateTime.Now.Year - birthday.Year;

Given that birthday is passed into an action method and is a DateTime object.

function leapYear(year)
{
  return ((year % 4 == 0) && (year % 100 != 0)) || (year % 400 == 0);
}

Use divmod:

now = int(time.time()) # epoch seconds
then = now - 90000 # some time in the past

d = divmod(now-then,86400)  # days
h = divmod(d[1],3600)  # hours
m = divmod(h[1],60)  # minutes
s = m[1]  # seconds

print '%d days, %d hours, %d minutes, %d seconds' % (d[0],h[0],m[0],s)

Here I'm just doing the difference between today, and a CREATED_DATE DATE field in a table, which obviously is a date in the past:

SELECT  
((FLOOR(ABS(MONTHS_BETWEEN(CREATED_DATE, SYSDATE))) / 12) * 12) || ' months, '  AS MONTHS,
-- we take total days - years(as days) - months(as days) to get remaining days
FLOOR((SYSDATE - CREATED_DATE) -      -- total days
(FLOOR((SYSDATE - CREATED_DATE)/365)*12)*(365/12) -      -- years, as days
-- this is total months - years (as months), to get number of months, 
-- then multiplied by 30.416667 to get months as days (and remove it from total days)
FLOOR(((SYSDATE - CREATED_DATE)/365)*12 - (FLOOR((SYSDATE - CREATED_DATE)/365)*12)) * (365/12))
|| ' days ' AS DAYS 
FROM MyTable

I use (365/12), or 30.416667, as my conversion factor because I'm using total days and removing years and months (as days) to get the remainder number of days. It was good enough for my purposes, anyway.

Yes: TIME_CREATED contains a date and a time. Use TRUNC to strip the time:

SELECT EMP_NAME, DEPT
FROM EMPLOYEE
WHERE TRUNC(TIME_CREATED) = TO_DATE('26/JAN/2011','dd/mon/yyyy')

UPDATE:
As Dave Costa points out in the comment below, this will prevent Oracle from using the index of the column TIME_CREATED if it exists. An alternative approach without this problem is this:

SELECT EMP_NAME, DEPT
FROM EMPLOYEE
WHERE TIME_CREATED >= TO_DATE('26/JAN/2011','dd/mon/yyyy') 
      AND TIME_CREATED < TO_DATE('26/JAN/2011','dd/mon/yyyy') + 1

Most / all answers caused issues for us when daylight savings time came around. Here's our working solution for all dates, without using JodaTime. It utilizes calendar objects:

public static int daysBetween(Calendar day1, Calendar day2){
    Calendar dayOne = (Calendar) day1.clone(),
            dayTwo = (Calendar) day2.clone();

    if (dayOne.get(Calendar.YEAR) == dayTwo.get(Calendar.YEAR)) {
        return Math.abs(dayOne.get(Calendar.DAY_OF_YEAR) - dayTwo.get(Calendar.DAY_OF_YEAR));
    } else {
        if (dayTwo.get(Calendar.YEAR) > dayOne.get(Calendar.YEAR)) {
            //swap them
            Calendar temp = dayOne;
            dayOne = dayTwo;
            dayTwo = temp;
        }
        int extraDays = 0;

        int dayOneOriginalYearDays = dayOne.get(Calendar.DAY_OF_YEAR);

        while (dayOne.get(Calendar.YEAR) > dayTwo.get(Calendar.YEAR)) {
            dayOne.add(Calendar.YEAR, -1);
            // getActualMaximum() important for leap years
            extraDays += dayOne.getActualMaximum(Calendar.DAY_OF_YEAR);
        }

        return extraDays - dayTwo.get(Calendar.DAY_OF_YEAR) + dayOneOriginalYearDays ;
    }
}

Use:

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

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

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

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

I prefer using an interval literal for this, because interval '30' minute or interval '5' second is a lot easier to read then 30 / (24 * 60) or 5 / (24 * 60 * 69)

e.g.

• some_date + interval '2' hour
• some_date + interval '30' minute
• some_date + interval '5' second
• some_date + interval '2' day

You can also combine several units into one expression:

• some_date + interval '2 3:06' day to minute

Adds 2 days, 3 hours and 6 minutes to the date value

The above is also standard SQL and also works in several other DBMS.

More details in the manual: https://docs.oracle.com/database/121/SQLRF/sql_elements003.htm#SQLRF00221

Use String.matches(), like:

String myString = "qwerty123456";
System.out.println(myString.matches("[A-Za-z0-9]+"));

That may not be the absolute "fastest" possible approach. But in general there's not much point in trying to compete with the people who write the language's "standard library" in terms of performance.

Use ModHeader Chrome extension.

Or you can try more complex value like Accept-Language: en-US,en;q=0.9,ru;q=0.8,th;q=0.7

The simplest way I found is to use BitmapDescriptorFactory.defaultMarker() the documentation even has an example of setting the color. From my own code:

MarkerOptions marker = new MarkerOptions()
            .title(formatInfo(data))
            .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE))
            .position(new LatLng(data.getLatitude(), data.getLongitude()))

The simplest solution would be a correlated sub select:

select
    A.*
from
    table_A A
where
    A.id in (
        select B.id from table_B B where B.tag = 'chair'
)

Alternatively you could join the tables and filter the rows you want:

select
    A.*
from
    table_A A
inner join table_B B
    on A.id = B.id
where
    B.tag = 'chair'

You should profile both and see which is faster on your dataset.

Taking answers from @Nicola and @Victor Wing and adding a more standardized way:

import org.springframework.beans.factory.InitializingBean;
import org.springframework.http.HttpStatus;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.http.server.ServerHttpResponse;
import org.springframework.http.server.ServletServerHttpResponse;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.AuthenticationEntryPoint;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class UnauthorizedErrorAuthenticationEntryPoint implements AuthenticationEntryPoint, InitializingBean {

    private HttpMessageConverter messageConverter;

    @SuppressWarnings("unchecked")
    @Override
    public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException exception) throws IOException, ServletException {

        MyGenericError error = new MyGenericError();
        error.setDescription(exception.getMessage());

        ServerHttpResponse outputMessage = new ServletServerHttpResponse(response);
        outputMessage.setStatusCode(HttpStatus.UNAUTHORIZED);

        messageConverter.write(error, null, outputMessage);
    }

    public void setMessageConverter(HttpMessageConverter messageConverter) {
        this.messageConverter = messageConverter;
    }

    @Override
    public void afterPropertiesSet() throws Exception {

        if (messageConverter == null) {
            throw new IllegalArgumentException("Property 'messageConverter' is required");
        }
    }

}

Now, you can inject configured Jackson, Jaxb or whatever you use to convert response bodies on your MVC annotation or XML based configuration with its serializers, deserializers and so on.

Alternatively you can write the same like

{
    test: /\.(svg|png|jpg|jpeg|gif)$/,
    include: 'path of input image directory',
    use: {
        loader: 'file-loader',
        options: {
            name: '[path][name].[ext]',
            outputPath: 'path of output image directory'
        }
    }
}

and then use simple import

import varName from 'relative path';

and in jsx write like <img src={varName} ..../>

.... are for other image attributes

You can't, you either need to keep the index separately:

int index = 0;
for(Element song : question) {
    System.out.println("Current index is: " + (index++));
}

or use a normal for loop:

for(int i = 0; i < question.length; i++) {
    System.out.println("Current index is: " + i);
}

The reason is you can use the condensed for syntax to loop over any Iterable, and it's not guaranteed that the values actually have an "index"

Just to include new Python f String compatible functionality:

var_a = 10

If it's a UI based application , then " I also need to know what I need to add to my code so that my program waits about 700 milliseconds for a keyinput before moving on to another method" you can use GlassPane or Timer class to fulfill the requirement.

For key Event:

public void keyPressed(KeyEvent e) {

    int key = e.getKeyCode();

    if (key == KeyEvent.VK_LEFT) {
        dx = -1;
    }

    if (key == KeyEvent.VK_RIGHT) {
        dx = 1;
    }

    if (key == KeyEvent.VK_UP) {
        dy = -1;
    }

    if (key == KeyEvent.VK_DOWN) {
        dy = 1;
    }
}

Add a new pandas.Series using pandas.DataFrame.append().

If you wish to specify the name (AKA the "index") of the new row, use:

df.append(pandas.Series(name='NameOfNewRow'))

If you don't wish to name the new row, use:

df.append(pandas.Series(), ignore_index=True)

where df is your pandas.DataFrame.

I was looking into this just now, and wasn't happy with the readability of the current solution. If you're writing code informally or on a small project, you can just add another item to the end of your enum called "Length". This way, you only need to type:

var namesCount = (int)MyEnum.Length;

Of course if others are going to use your code - or I'm sure under many other circumstances that didn't apply to me in this case - this solution may be anywhere from ill advised to terrible.

This should be fine:

const char* bool_cast(const bool b) {
    return b ? "true" : "false";
}

But, if you want to do it more C++-ish:

#include <iostream>
#include <string>
#include <sstream>
using namespace std;

string bool_cast(const bool b) {
    ostringstream ss;
    ss << boolalpha << b;
    return ss.str();
}

int main() {
    cout << bool_cast(true) << "\n";
    cout << bool_cast(false) << "\n";
}

This article:

• NOT IN vs. NOT EXISTS vs. LEFT JOIN / IS NULL: SQL Server

may be if interest to you.

In a couple of words, this query:

SELECT  d1.short_code
FROM    domain1 d1
LEFT JOIN
        domain2 d2
ON      d2.short_code = d1.short_code
WHERE   d2.short_code IS NULL

will work but it is less efficient than a NOT NULL (or NOT EXISTS) construct.

You can also use this:

SELECT  short_code
FROM    domain1
EXCEPT
SELECT  short_code
FROM    domain2

This is using neither NOT IN nor WHERE (and even no joins!), but this will remove all duplicates on domain1.short_code if any.

go to cmd get into file directory and type jupyter notebook filename.ipynb in my case it open code editor and provide local host connection string copy that string and paste in any browser!done

all_of (begin(R), end(R), [](auto&p){ exists(p); })

where R is your sequence of path-like things, and exists() is from the future std or current boost. If you roll your own, keep it simple,

bool exists (string const& p) { return ifstream{p}; }

The branched solution isn't absolutely terrible and it won't gobble file descriptors,

I have tried this pure component:

const RawHTML = ({children, className = ""}) => 
<div className={className}
  dangerouslySetInnerHTML={{ __html: children.replace(/\n/g, '<br />')}} />

Features

• Takes classNameprop (easier to style it)
• Replaces \n to <br /> (you often want to do that)
• Place content as children when using the component like:
• <RawHTML>{myHTML}</RawHTML>

I have placed the component in a Gist at Github: RawHTML: ReactJS pure component to render HTML

Use os.path.normpath, then os.path.basename:

>>> os.path.basename(os.path.normpath('/folderA/folderB/folderC/folderD/'))
'folderD'

The first strips off any trailing slashes, the second gives you the last part of the path. Using only basename gives everything after the last slash, which in this case is ''.

If you use it in a database, this is a good way:

Set the ip field in database to varchar(250), and then use this:

$theip = $_SERVER["REMOTE_ADDR"];

if (!empty($_SERVER["HTTP_X_FORWARDED_FOR"])) {
    $theip .= '('.$_SERVER["HTTP_X_FORWARDED_FOR"].')';
}

if (!empty($_SERVER["HTTP_CLIENT_IP"])) {
    $theip .= '('.$_SERVER["HTTP_CLIENT_IP"].')';
}

$realip = substr($theip, 0, 250);

Then you just check $realip against the database ip field

Postgres hasn't implemented an equivalent to INSERT OR REPLACE. From the ON CONFLICT docs (emphasis mine):

It can be either DO NOTHING, or a DO UPDATE clause specifying the exact details of the UPDATE action to be performed in case of a conflict.

Though it doesn't give you shorthand for replacement, ON CONFLICT DO UPDATE applies more generally, since it lets you set new values based on preexisting data. For example:

INSERT INTO users (id, level)
VALUES (1, 0)
ON CONFLICT (id) DO UPDATE
SET level = users.level + 1;

Within the package there is a class called JwtSecurityTokenHandler which derives from System.IdentityModel.Tokens.SecurityTokenHandler. In WIF this is the core class for deserialising and serialising security tokens.

The class has a ReadToken(String) method that will take your base64 encoded JWT string and returns a SecurityToken which represents the JWT.

The SecurityTokenHandler also has a ValidateToken(SecurityToken) method which takes your SecurityToken and creates a ReadOnlyCollection<ClaimsIdentity>. Usually for JWT, this will contain a single ClaimsIdentity object that has a set of claims representing the properties of the original JWT.

JwtSecurityTokenHandler defines some additional overloads for ValidateToken, in particular, it has a ClaimsPrincipal ValidateToken(JwtSecurityToken, TokenValidationParameters) overload. The TokenValidationParameters argument allows you to specify the token signing certificate (as a list of X509SecurityTokens). It also has an overload that takes the JWT as a string rather than a SecurityToken.

The code to do this is rather complicated, but can be found in the Global.asax.cx code (TokenValidationHandler class) in the developer sample called "ADAL - Native App to REST service - Authentication with ACS via Browser Dialog", located at

http://code.msdn.microsoft.com/AAL-Native-App-to-REST-de57f2cc

Alternatively, the JwtSecurityToken class has additional methods that are not on the base SecurityToken class, such as a Claims property that gets the contained claims without going via the ClaimsIdentity collection. It also has a Payload property that returns a JwtPayload object that lets you get at the raw JSON of the token. It depends on your scenario which approach it most appropriate.

The general (i.e. non JWT specific) documentation for the SecurityTokenHandler class is at

http://msdn.microsoft.com/en-us/library/system.identitymodel.tokens.securitytokenhandler.aspx

Depending on your application, you can configure the JWT handler into the WIF pipeline exactly like any other handler.

There are 3 samples of it in use in different types of application at

http://code.msdn.microsoft.com/site/search?f%5B0%5D.Type=SearchText&f%5B0%5D.Value=aal&f%5B1%5D.Type=User&f%5B1%5D.Value=Azure%20AD%20Developer%20Experience%20Team&f%5B1%5D.Text=Azure%20AD%20Developer%20Experience%20Team

Probably, one will suite your needs or at least be adaptable to them.

What Arne said - you can't reliably style select boxes and have them look anything like consistent across browsers.

Uniform: https://github.com/pixelmatrix/uniform is a javascript solution which gives you good graphic control over your form elements - it's still Javascript, but it's about as nice as javascript gets for solving this problem.

Please! please! please! DO NOT serialize data and place it into your database. Serialize can be used that way, but that's missing the point of a relational database and the datatypes inherent in your database engine. Doing this makes data in your database non-portable, difficult to read, and can complicate queries. If you want your application to be portable to other languages, like let's say you find that you want to use Java for some portion of your app that it makes sense to use Java in, serialization will become a pain in the buttocks. You should always be able to query and modify data in the database without using a third party intermediary tool to manipulate data to be inserted.

it makes really difficult to maintain code, code with portability issues, and data that is it more difficult to migrate to other RDMS systems, new schema, etc. It also has the added disadvantage of making it messy to search your database based on one of the fields that you've serialized.

That's not to say serialize() is useless. It's not... A good place to use it may be a cache file that contains the result of a data intensive operation, for instance. There are tons of others... Just don't abuse serialize because the next guy who comes along will have a maintenance or migration nightmare.

A good example of serialize() and unserialize() could be like this:

$posts = base64_encode(serialize($_POST));
header("Location: $_SERVER[REQUEST_URI]?x=$posts");

Unserialize on the page

if($_GET['x']) {
   // unpack serialize and encoded URL
   $_POST = unserialize(base64_decode($_GET['x']));
}

Why Server.Transfer? Response.Redirect(Request.RawUrl) would get you what you need.

You can also try this

// create a thread  
Thread newWindowThread = new Thread(new ThreadStart(() =>  
{  
    // create and show the window
    FaxImageLoad obj = new FaxImageLoad(destination);  
    obj.Show();  
    
    // start the Dispatcher processing  
    System.Windows.Threading.Dispatcher.Run();  
}));  

// set the apartment state  
newWindowThread.SetApartmentState(ApartmentState.STA);  

// make the thread a background thread  
newWindowThread.IsBackground = true;  

// start the thread  
newWindowThread.Start();  

Quick 'n dirty, regex-free, low-robustness chop-chop technique

string="US/Central - 10:26 PM (CST)"
etime="${string% [AP]M*}"
etime="${etime#* - }"

what you are doing here is reading one character at a time from the input stream and assume that all the characters between " " represent a word. BUT it's unlikely to be a " " after the last word, so that's probably why it does not work:

"word1 word2 word2EOF"

Use the range's NumberFormat property to force the format of the range like this:

Sheet1.Range("A2", "A50000").NumberFormat = "yyyy-mm-dd"

I have a pinball prototype that also gave me much trouble in the same areas. These are all the steps I've taken to almost (but not yet entirely) solve these problems:

For fast moving objects:

• Set the rigidbody's Interpolate to 'Interpolate' (this does not affect the actual physics simulation, but updates the rendering of the object properly - use this only on important objects from a rendering point of view, like the player, or a pinball, but not for projectiles)

• Set Collision Detection to Continuous Dynamic

• Attach the script DontGoThroughThings (https://www.auto.tuwien.ac.at/wordpress/?p=260) to your object. This script cleverly uses the Raycasting solution I posted in my other answer to pull back offending objects to before the collision points.

In Edit -> Project Settings -> Physics:

• Set Min Penetration for Penalty to a very low value. I've set mine to 0.001

• Set Solver Iteration Count to a higher value. I've set mine to 50, but you can probably do ok with much less.

All that is going to have a penalty in performace, but that's unavoidable. The defaults values are soft on performance but are not really intented for proper simulation of small and fast-moving objects.

I recently came up with the following convention for naming my tests, their classes and containing projects in order to maximize their descriptivenes:

Lets say I am testing the Settings class in a project in the MyApp.Serialization namespace.

First I will create a test project with the MyApp.Serialization.Tests namespace.

Within this project and of course the namespace I will create a class called IfSettings (saved as IfSettings.cs).

Lets say I am testing the SaveStrings() method. -> I will name the test CanSaveStrings().

When I run this test it will show the following heading:

MyApp.Serialization.Tests.IfSettings.CanSaveStrings

I think this tells me very well, what it is testing.

Of course it is usefull that in English the noun "Tests" is the same as the verb "tests".

There is no limit to your creativity in naming the tests, so that we get full sentence headings for them.

Usually the Test names will have to start with a verb.

Examples include:

• Detects (e.g. DetectsInvalidUserInput)
• Throws (e.g. ThrowsOnNotFound)
• Will (e.g. WillCloseTheDatabaseAfterTheTransaction)

etc.

Another option is to use "that" instead of "if".

The latter saves me keystrokes though and describes more exactly what I am doing, since I don't know, that the tested behavior is present, but am testing if it is.

[Edit]

After using above naming convention for a little longer now, I have found, that the If prefix can be confusing, when working with interfaces. It just so happens, that the testing class IfSerializer.cs looks very similar to the interface ISerializer.cs in the "Open Files Tab". This can get very annoying when switching back and forth between the tests, the class being tested and its interface. As a result I would now choose That over If as a prefix.

Additionally I now use - only for methods in my test classes as it is not considered best practice anywhere else - the "_" to separate words in my test method names as in:

[Test] public void detects_invalid_User_Input()

I find this to be easier to read.

[End Edit]

I hope this spawns some more ideas, since I consider naming tests of great importance as it can save you a lot of time that would otherwise have been spent trying to understand what the tests are doing (e.g. after resuming a project after an extended hiatus).

YES YOU CAN do it!! It's a little tricky way ; ) (it almost works on ios)

var iframe = document.createElement("IFRAME");
iframe.setAttribute("src", 'data:text/plain,');
document.documentElement.appendChild(iframe);
if(window.frames[0].window.confirm("Are you sure?")){
    // what to do if answer "YES"
}else{
    // what to do if answer "NO"
}

Enjoy it!

The question is tricky in java (and probably also in other language).

A Integer is a 32-bit signed data type, but Integer.toBinaryString() returns a string representation of the integer argument as an unsigned integer in base 2.

So, Integer.parseInt(Integer.toBinaryString(X),2) can generate an exception (signed vs. unsigned).

The safe way is to use Integer.toString(X,2); this will generate something less elegant:

-11110100110

But it works!!!

Note: The first() method doesn't throw an exception as described in the original question. If you're getting this kind of exception, there is another error in your code.

The correct way to user first() and check for a result:

$user = User::where('mobile', Input::get('mobile'))->first(); // model or null
if (!$user) {
   // Do stuff if it doesn't exist.
}

Other techniques (not recommended, unnecessary overhead):

$user = User::where('mobile', Input::get('mobile'))->get();

if (!$user->isEmpty()){
    $firstUser = $user->first()
}

or

try {
    $user = User::where('mobile', Input::get('mobile'))->firstOrFail();
    // Do stuff when user exists.
} catch (ErrorException $e) {
    // Do stuff if it doesn't exist.
}

or

// Use either one of the below. 
$users = User::where('mobile', Input::get('mobile'))->get(); //Collection

if (count($users)){
    // Use the collection, to get the first item use $users->first().
    // Use the model if you used ->first();
}

Each one is a different way to get your required result.

Watch out if you are aiming at integers, like 1,2,3,4,5. If you intend to use the elements of your array as integers and not as strings after splitting the string, consider converting them into such.

var str = "1,2,3,4,5,6";
var temp = new Array();
// This will return an array with strings "1", "2", etc.
temp = str.split(",");

Adding a loop like this,

for (a in temp ) {
    temp[a] = parseInt(temp[a], 10); // Explicitly include base as per Álvaro's comment
}

will return an array containing integers, and not strings.

This is the way I do the pattern match:

val result = JSON.parseFull(jsonStr)
result match {
  // Matches if jsonStr is valid JSON and represents a Map of Strings to Any
  case Some(map: Map[String, Any]) => println(map)
  case None => println("Parsing failed")
  case other => println("Unknown data structure: " + other)
}

You just use an ImageButton and make the background whatever you want and set the icon as the src.

<ImageButton
    android:id="@+id/ImageButton01"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/album_icon"
    android:background="@drawable/round_button" />

Use this:

for file in `ls *.Zip`; do
unzip ${file} -d ${unzip_dir_loc}
done

If someone is strugling with axios to make this work this helped me:

just try this in our style

white-space: normal;

Generally speaking:

all and any are functions that take some iterable and return True, if

• in the case of all(), no values in the iterable are falsy;
• in the case of any(), at least one value is truthy.

A value x is falsy iff bool(x) == False. A value x is truthy iff bool(x) == True.

Any non-booleans in the iterable will be fine — bool(x) will coerce any x according to these rules: 0, 0.0, None, [], (), [], set(), and other empty collections will yield False, anything else True. The docstring for bool uses the terms 'true'/'false' for 'truthy'/'falsy', and True/False for the concrete boolean values.

In your specific code samples:

You misunderstood a little bit how these functions work. Hence, the following does something completely not what you thought:

if any(foobars) == big_foobar:

...because any(foobars) would first be evaluated to either True or False, and then that boolean value would be compared to big_foobar, which generally always gives you False (unless big_foobar coincidentally happened to be the same boolean value).

Note: the iterable can be a list, but it can also be a generator/generator expression (˜ lazily evaluated/generated list) or any other iterator.

What you want instead is:

if any(x == big_foobar for x in foobars):

which basically first constructs an iterable that yields a sequence of booleans—for each item in foobars, it compares the item to big_foobar and emits the resulting boolean into the resulting sequence:

tmp = (x == big_foobar for x in foobars)

then any walks over all items in tmp and returns True as soon as it finds the first truthy element. It's as if you did the following:

In [1]: foobars = ['big', 'small', 'medium', 'nice', 'ugly']                                        

In [2]: big_foobar = 'big'                                                                          

In [3]: any(['big' == big_foobar, 'small' == big_foobar, 'medium' == big_foobar, 'nice' == big_foobar, 'ugly' == big_foobar])        
Out[3]: True

Note: As DSM pointed out, any(x == y for x in xs) is equivalent to y in xs but the latter is more readable, quicker to write and runs faster.

Some examples:

In [1]: any(x > 5 for x in range(4))
Out[1]: False

In [2]: all(isinstance(x, int) for x in range(10))
Out[2]: True

In [3]: any(x == 'Erik' for x in ['Erik', 'John', 'Jane', 'Jim'])
Out[3]: True

In [4]: all([True, True, True, False, True])
Out[4]: False

There are couple of ways to initialize the const members inside the class..

Definition of const member in general, needs initialization of the variable too..

1) Inside the class , if you want to initialize the const the syntax is like this

static const int a = 10; //at declaration

2) Second way can be

class A
{
  static const int a; //declaration
};

const int A::a = 10; //defining the static member outside the class

3) Well if you don't want to initialize at declaration, then the other way is to through constructor, the variable needs to be initialized in the initialization list(not in the body of the constructor). It has to be like this

class A
{
  const int b;
  A(int c) : b(c) {} //const member initialized in initialization list
};

For anyone that is looking for an easy solution in Visual Studio Community 2019, Fine Code Coverage is simple but it works well.

It cannot give accurate numbers on the precise coverage, but it will tell which lines are being covered with green/red gutters.

If you have a situation where you are using dynamic columns in your pivot statement you could use the following:

DECLARE @cols               NVARCHAR(MAX)
DECLARE @colsWithNoNulls    NVARCHAR(MAX)
DECLARE @query              NVARCHAR(MAX)

SET @cols = STUFF((SELECT distinct ',' + QUOTENAME(Name) 
            FROM Hospital
            WHERE Active = 1 AND StateId IS NOT NULL
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')

SET @colsWithNoNulls = STUFF(
            (
                SELECT distinct ',ISNULL(' + QUOTENAME(Name) + ', ''No'') ' + QUOTENAME(Name)
                FROM Hospital
                WHERE Active = 1 AND StateId IS NOT NULL
                FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')

EXEC ('
        SELECT Clinician, ' + @colsWithNoNulls + '
        FROM
        (
            SELECT DISTINCT p.FullName AS Clinician, h.Name, CASE WHEN phl.personhospitalloginid IS NOT NULL THEN ''Yes'' ELSE ''No'' END AS HasLogin
            FROM Person p
            INNER JOIN personlicense pl ON pl.personid = p.personid

            LEFT JOIN PersonHospitalLogin phl ON phl.personid = p.personid AND phl.HospitalId = h.hospitalid
            WHERE ltg.Name = ''RN'' AND
                pl.licenseactivestatusid = 2 AND
                h.Active = 1 AND

Java script plays on browser where java code is server side thing so you can't simply do this.

What you can do is submit the calculated variable from javascript to server by form-submission, or using URL parameter or using AJAX calls and then you can make it available on server

HTML

<input type="hidden" id="hiddenField"/>

make sure this fields lays under <form>

Javascript

document.getElementById("hiddenField").value=yourCalculatedVariable;

on server you would get this as a part of request

                                F(n)
                                /    \
                            F(n-1)   F(n-2)
                            /   \     /      \
                        F(n-2) F(n-3) F(n-3)  F(n-4)
                       /    \
                     F(n-3) F(n-4)

Important point to note is this algorithm is exponential because it does not store the result of previous calculated numbers. eg F(n-3) is called 3 times.

For more details refer algorithm by dasgupta chapter 0.2

try

total.Text = DateTime.Now.ToString()

or

Dim theDate As DateTime = System.DateTime.Now
total.Text = theDate.ToString()

You declare Start as an Integer, while you are trying to put a DateTime in it, which is not possible.

In android gradle 0.4.0 you can just do:

If your database client connects with TCP/IP and you have ident auth configured in your pg_hba.conf check that you have an identd installed and running. This is mandatory even if you have only local clients connecting to "localhost".

Also beware that nowadays the identd may have to be IPv6 enabled for Postgresql to welcome clients which connect to localhost.

The comment by MK pointed me in the right direction.

In the case of Apache 2.4 and up, there are different defaults and a new directive.

I am running Apache 2.4.6, and I had to add the following directives to get it working:

SSLProxyEngine on
SSLProxyVerify none 
SSLProxyCheckPeerCN off
SSLProxyCheckPeerName off
SSLProxyCheckPeerExpire off

Props can change when a component's parent renders the component again with different properties. I think this is mostly an optimization so that no new component needs to be instantiated.

this.setState({abc: {xyz: 'new value'}}); will NOT work, as state.abc will be entirely overwritten, not merged.

This works for me:

this.setState((previousState) => {
  previousState.abc.xyz = 'blurg';
  return previousState;
});

Unless I'm reading the docs wrong, Facebook recommends the above format. https://facebook.github.io/react/docs/component-api.html

Additionally, I guess the most direct way without mutating state is to directly copy by using the ES6 spread/rest operator:

const newState = { ...this.state.abc }; // deconstruct state.abc into a new object-- effectively making a copy
newState.xyz = 'blurg';
this.setState(newState);

You should be able to access the document in the IFRAME using the following code:

document.getElementById('myframe').contentWindow.document

However, you will not be able to do this if the page in the frame is loaded from a different domain (such as google.com). THis is because of the browser's Same Origin Policy.

This blog post explains it perfectly: Ruby's Exception vs StandardError: What's the difference?

Why you shouldn't rescue Exception

The problem with rescuing Exception is that it actually rescues every exception that inherits from Exception. Which is....all of them!

That's a problem because there are some exceptions that are used internally by Ruby. They don't have anything to do with your app, and swallowing them will cause bad things to happen.

Here are a few of the big ones:

• SignalException::Interrupt - If you rescue this, you can't exit your app by hitting control-c.

• ScriptError::SyntaxError - Swallowing syntax errors means that things like puts("Forgot something) will fail silently.

• NoMemoryError - Wanna know what happens when your program keeps running after it uses up all the RAM? Me neither.

begin
  do_something()
rescue Exception => e
  # Don't do this. This will swallow every single exception. Nothing gets past it. 
end

I'm guessing that you don't really want to swallow any of these system-level exceptions. You only want to catch all of your application level errors. The exceptions caused YOUR code.

Luckily, there's an easy way to to this.

Rescue StandardError Instead

All of the exceptions that you should care about inherit from StandardError. These are our old friends:

NoMethodError - raised when you try to invoke a method that doesn't exist

TypeError - caused by things like 1 + ""

RuntimeError - who could forget good old RuntimeError?

To rescue errors like these, you'll want to rescue StandardError. You COULD do it by writing something like this:

begin
  do_something()
rescue StandardError => e
  # Only your app's exceptions are swallowed. Things like SyntaxErrror are left alone. 
end

But Ruby has made it much easier for use.

When you don't specify an exception class at all, ruby assumes you mean StandardError. So the code below is identical to the above code:

begin
  do_something()
rescue => e
  # This is the same as rescuing StandardError
end

You can use the .complete property of the Javascript image class.

I have an application where I store a number of Image objects in an array, that will be dynamically added to the screen, and as they're loading I write updates to another div on the page. Here's a code snippet:

var gAllImages = [];

function makeThumbDivs(thumbnailsBegin, thumbnailsEnd)
{
    gAllImages = [];

    for (var i = thumbnailsBegin; i < thumbnailsEnd; i++) 
    {
        var theImage = new Image();
        theImage.src = "thumbs/" + getFilename(globals.gAllPageGUIDs[i]);
        gAllImages.push(theImage);

        setTimeout('checkForAllImagesLoaded()', 5);
        window.status="Creating thumbnail "+(i+1)+" of " + thumbnailsEnd;

        // make a new div containing that image
        makeASingleThumbDiv(globals.gAllPageGUIDs[i]);
    }
}

function checkForAllImagesLoaded()
{
    for (var i = 0; i < gAllImages.length; i++) {
        if (!gAllImages[i].complete) {
            var percentage = i * 100.0 / (gAllImages.length);
            percentage = percentage.toFixed(0).toString() + ' %';

            userMessagesController.setMessage("loading... " + percentage);
            setTimeout('checkForAllImagesLoaded()', 20);
            return;
        }
    }

    userMessagesController.setMessage(globals.defaultTitle);
}

you can try this: 1. ensure you have added: compile 'com.android.support:design:25.3.1' (maybe you also should add compile 'com.android.support.constraint:constraint-layout:1.0.2') 2.

If Windows fails to enumerate the device which is reported in Device Manager as error code 43:

• Install this Compatibility update from Windows.
• If you already have this update but you get this error, restart your PC (unfortunately, it happened to me, I tried everything until I thought what if I restart...).

If the device is listed in Device Manager as Other devices -> Android but reports an error code 28:

• Google USB Driver didn't work for me. You could try your corresponding OEM USB Drivers, but in my case my device is not listed there.
• So, install the latest Samsung drivers: SAMSUNG USB Driver v1.7.23.0
• Restart the computer (very important)
• Go to Device Manager, find the Android device, and select Update Driver Software.
• Select Browse my computer for driver software
• Select Let me pick from a list of device drivers on my computer
• Select ADB Interface from the list
• Select SAMSUNG Android ADB Interface (this is a signed driver). If you get a warning, select Yes to continue.
• Done!

By doing this I was able to use my tablet for development under Windows 8.1.

Note: This solution uses Samsung drivers but works for other devices.

You can use something like this scopeValue[field], but if your field is in another object you will need another solution.

To solve all kind of situations, you can use this directive:

this.app.directive('dynamicModel', ['$compile', '$parse', function ($compile, $parse) {
    return {
        restrict: 'A',
        terminal: true,
        priority: 100000,
        link: function (scope, elem) {
            var name = $parse(elem.attr('dynamic-model'))(scope);
            elem.removeAttr('dynamic-model');
            elem.attr('ng-model', name);
            $compile(elem)(scope);
        }
    };
}]);

Html example:

<input dynamic-model="'scopeValue.' + field" type="text">

If you set up a click binding in Knockout the event is passed as the second parameter. You can use the event to obtain the element that the click occurred on and perform whatever action you want.

Here is a fiddle that demonstrates: http://jsfiddle.net/jearles/xSKyR/

Alternatively, you could create your own custom binding, which will receive the element it is bound to as the first parameter. On init you could attach your own click event handler to do any actions you wish.

http://knockoutjs.com/documentation/custom-bindings.html

<div>
    <button data-bind="click: clickMe">Click Me!</button>
</div>

var ViewModel = function() {
    var self = this;
    self.clickMe = function(data,event) {

      var target = event.target || event.srcElement;

      if (target.nodeType == 3) // defeat Safari bug
        target = target.parentNode;

      target.parentNode.innerHTML = "something";
    }
}

ko.applyBindings(new ViewModel());

just replace the "version.txt" with your file that is always run and "version" with the name you want to use for your local storage.

You can achieve with below queries

1. select extract(xmltype(xml), '//fax/text()').getStringVal() from mytab;

2. select extractvalue(xmltype(xml), '//fax') from mytab;

This it the best way to calculate the size of a directory. Only other way would still use recursion but be a bit easier to use and isn't as flexible.

float folderSize = 0.0f;
FileInfo[] files = Directory.GetFiles(folder, "*", SearchOption.AllDirectories);
foreach(FileInfo file in files) folderSize += file.Length;

:sh then ctrl+d to get back in (bash)

Update:

You could map ctrl+d in vim to run :sh, which allows you to toggle between bash and vim quickly.

noremap <C-d> :sh<cr>

This is also known as the "inline if", or as above the ternary operator. https://en.wikipedia.org/wiki/%3F:

It's used to reduce code, though it's not recommended to use a lot of these on a single line as it may make maintaining code quite difficult. Imagine:

a = b?c:(d?e:(f?g:h));

and you could go on a while.

It ends up basically the same as writing:

if(b)
  a = c;
else if(d)
  a = e;
else if(f)
  a = g;
else
  a = h;

In your case, "string requestUri = _apiURL + "?e=" + OperationURL[0] + ((OperationURL[1] == "GET") ? GetRequestSignature() : "");"

Can also be written as: (omitting the else, since it's an empty string)

string requestUri = _apiURL + "?e=" + OperationURL[0];
if((OperationURL[1] == "GET")
    requestUri = requestUri + GetRequestSignature();

or like this:

string requestUri;
if((OperationURL[1] == "GET")
    requestUri = _apiURL + "?e=" + OperationURL[0] + GetRequestSignature();
else
    requestUri = _apiURL + "?e=" + OperationURL[0];

Depending on your preference / the code style your boss tells you to use.

new Date().getTime();

For more information, see @James McMahon's answer.

The calculation occurs immediately since the calculation call is bound in the template, which displays its result when quantity changes.

Instead you could try the following approach. Change your markup to the following:

<div ng-controller="myAppController" style="text-align:center">
  <p style="font-size:28px;">Enter Quantity:
      <input type="text" ng-model="quantity"/>
  </p>
  <button ng-click="calculateQuantity()">Calculate</button>
  <h2>Total Cost: Rs.{{quantityResult}}</h2>
</div>

Next, update your controller:

myAppModule.controller('myAppController', function($scope,calculateService) {
  $scope.quantity=1;
  $scope.quantityResult = 0;

  $scope.calculateQuantity = function() {
    $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  };
});

Here's a JSBin example that demonstrates the above approach.

The problem with this approach is the calculated result remains visible with the old value till the button is clicked. To address this, you could hide the result whenever the quantity changes.

This would involve updating the template to add an ng-change on the input, and an ng-if on the result:

<input type="text" ng-change="hideQuantityResult()" ng-model="quantity"/>

and

<h2 ng-if="showQuantityResult">Total Cost: Rs.{{quantityResult}}</h2>

In the controller add:

$scope.showQuantityResult = false;

$scope.calculateQuantity = function() {
  $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  $scope.showQuantityResult = true;
};

$scope.hideQuantityResult = function() {
  $scope.showQuantityResult = false;
}; 

These updates can be seen in this JSBin demo.

Have you tried starting it as an administrator? Start Visual Studio as an administrator if you use it, because working with .bat files requires those privileges.

Using Guava you can easily combine different type of criteria. For your specific solution you can use:

value = CharMatcher.inRange('0', '9')
        .or(CharMatcher.inRange('a', 'z')
        .or(CharMatcher.inRange('A', 'Z'))).retainFrom(value)

I think that this below is accurate and it may help. Feel free to correct it if you find any errors. I'm new at C.

char str[]  

1. array of values of type char, with its own address in memory
2. array of values of type char, with its own address in memory as many consecutive addresses as elements in the array

3. including termination null character '\0' &str, &str[0] and str, all three represent the same location in memory which is address of the first element of the array str

   char *strPtr = &str[0]; //declaration and initialization

alternatively, you can split this in two:

char *strPtr; strPtr = &str[0];

4. strPtr is a pointer to a char
5. strPtr points at array str
6. strPtr is a variable with its own address in memory
7. strPtr is a variable that stores value of address &str[0]
8. strPtr own address in memory is different from the memory address that it stores (address of array in memory a.k.a &str[0])
9. &strPtr represents the address of strPtr itself

I think that you could declare a pointer to a pointer as:

char **vPtr = &strPtr;  

declares and initializes with address of strPtr pointer

Alternatively you could split in two:

char **vPtr;
*vPtr = &strPtr

10. *vPtr points at strPtr pointer
11. *vPtr is a variable with its own address in memory
12. *vPtr is a variable that stores value of address &strPtr
13. final comment: you can not do str++, str address is a const, but you can do strPtr++

The CSS documentation contains industry-standard CSS equivalent for all HTML constructs. That is: most web browsers these days do not explicitly handle SUB, SUP, B, I and so on - they (kinda sorta) are converted into SPAN elements with appropriate CSS properties, and the rendering engine only deals with that.

The page is Appendix D. Default style sheet for HTML 4

The bits you want are:

small, sub, sup { font-size: .83em }
sub             { vertical-align: sub }
sup             { vertical-align: super }

Return a FileResult or FileStreamResult from your action, depending on whether the file exists or you create it on the fly.

public ActionResult GetPdf(string filename)
{
    return File(filename, "application/pdf", Server.UrlEncode(filename));
}

I cannot help you much without a small (possibly reduced) snippit of the problem. If the problem is what I think it is then it's because a div by default takes up 100% width, and as such cannot be aligned.

What you may be after is to align the inline elements inside the div (such as text) with text-align:center; otherwise you may consider setting the div to display:inline-block;

If you do go down the inline-block route then you may have to consider my favorite IE hack.

width:100px;
display:inline-block;
zoom:1; //IE only
*display:inline; //IE only

Happy Coding :)

You need to use the alias directive for location /static:

server {

  index index.html;
  server_name test.example.com;

  root /web/test.example.com/www;

  location /static/ {
    alias /web/test.example.com/static/;
  }

}

The nginx wiki explains the difference between root and alias better than I can:

Note that it may look similar to the root directive at first sight, but the document root doesn't change, just the file system path used for the request. The location part of the request is dropped in the request Nginx issues.

Note that root and alias handle trailing slashes differently.

If you don't want it to add it to a link, you can just enclose it within a span and that would work.

<span id='clickableAwesomeFont'><i class="fa fa-behance-square fa-4x"></span>

in your css, then you can:

#clickableAwesomeFont {
     cursor: pointer
}

Then in java script, you can just add a click handler.

In cases where it's actually not a link, I think this is much cleaner and using a link would be changing its semantics and abusing its meaning.

Wouldn't this work:

 SELECT email FROM table1 t1 
          where UNIQUE(SELECT * FROM table1 t2); 

If you use Object Relational Mapping tools or will in the future I suggest Singular.

Some tools like LLBLGen can automatically correct plural names like Users to User without changing the table name itself. Why does this matter? Because when it's mapped you want it to look like User.Name instead of Users.Name or worse from some of my old databases tables naming tblUsers.strName which is just confusing in code.

My new rule of thumb is to judge how it will look once it's been converted into an object.

one table I've found that does not fit the new naming I use is UsersInRoles. But there will always be those few exceptions and even in this case it looks fine as UsersInRoles.Username.

To use center alignment in ionic app code itself, you can use the following code:

<ion-row center>  
 <ion-col text-center>   
  <button ion-button>Search</button>  
 </ion-col> 
</ion-row>

To use right alignment in ionic app code itself, you can use the following code:

<ion-row right>  
 <ion-col text-right>   
  <button ion-button>Search</button>  
 </ion-col> 
</ion-row>

Almost four years after asking this question, I have finally found an answer that completely satisfies me!

See the details in github:help's guide to Dealing with line endings.

Git allows you to set the line ending properties for a repo directly using the text attribute in the .gitattributes file. This file is committed into the repo and overrides the core.autocrlf setting, allowing you to ensure consistent behaviour for all users regardless of their git settings.

And thus

The advantage of this is that your end of line configuration now travels with your repository and you don't need to worry about whether or not collaborators have the proper global settings.

Here's an example of a .gitattributes file

# Auto detect text files and perform LF normalization
*        text=auto

*.cs     text diff=csharp
*.java   text diff=java
*.html   text diff=html
*.css    text
*.js     text
*.sql    text

*.csproj text merge=union
*.sln    text merge=union eol=crlf

*.docx   diff=astextplain
*.DOCX   diff=astextplain

# absolute paths are ok, as are globs
/**/postinst* text eol=lf

# paths that don't start with / are treated relative to the .gitattributes folder
relative/path/*.txt text eol=lf

There is a convenient collection of ready to use .gitattributes files for the most popular programming languages. It's useful to get you started.

Once you've created or adjusted your .gitattributes, you should perform a once-and-for-all line endings re-normalization.

Note that the GitHub Desktop app can suggest and create a .gitattributes file after you open your project's Git repo in the app. To try that, click the gear icon (in the upper right corner) > Repository settings ... > Line endings and attributes. You will be asked to add the recommended .gitattributes and if you agree, the app will also perform a normalization of all the files in your repository.

Finally, the Mind the End of Your Line article provides more background and explains how Git has evolved on the matters at hand. I consider this required reading.

You've probably got users in your team who use EGit or JGit (tools like Eclipse and TeamCity use them) to commit their changes. Then you're out of luck, as @gatinueta explained in this answer's comments:

This setting will not satisfy you completely if you have people working with Egit or JGit in your team, since those tools will just ignore .gitattributes and happily check in CRLF files https://bugs.eclipse.org/bugs/show_bug.cgi?id=342372

One trick might be to have them commit their changes in another client, say SourceTree. Our team back then preferred that tool to Eclipse's EGit for many use cases.

Who said software is easy? :-/

You can turn autocommit ON by setting implicit_transactions OFF:

SET IMPLICIT_TRANSACTIONS OFF

When the setting is ON, it returns to implicit transaction mode. In implicit transaction mode, every change you make starts a transactions which you have to commit manually.

Maybe an example is clearer. This will write a change to the database:

SET IMPLICIT_TRANSACTIONS ON
UPDATE MyTable SET MyField = 1 WHERE MyId = 1
COMMIT TRANSACTION

This will not write a change to the database:

SET IMPLICIT_TRANSACTIONS ON
UPDATE MyTable SET MyField = 1 WHERE MyId = 1
ROLLBACK TRANSACTION

The following example will update a row, and then complain that there's no transaction to commit:

SET IMPLICIT_TRANSACTIONS OFF
UPDATE MyTable SET MyField = 1 WHERE MyId = 1
ROLLBACK TRANSACTION

Like Mitch Wheat said, autocommit is the default for Sql Server 2000 and up.

Since Java doesn't have an intersect function (really!?) you can do collision detection by simply comparying the X and Y, Width and Height values of the bounding boxes (rectangle) for each of the objects that could potentially collide.

So... in the base object of each colliding object... i.e. if your player and enemy have a common base you can put a simple Rectangle object called something like BoundingBox. If the common base is a built in Java class then you'll need to create a class that extends the build in class and have the player and enemy objects extend your new class or are instances of that class.

At creation (and each tick or update) you'll need to set the BoundingBox paremeters for both your player and enemy. I don't have the Rectangle class infront of me but its most likely something like X, Y, Width and finally Height. X and Y are that objects location in your game world. The width and height are self explanatory I think. They'll most likely come out from the right of the players location though so, if the X and Y were bothe at 0 and your Width and Height were both at 256 you wouldn't see anything because the character would be at the top left outside of the screen.

Anyways... to detect a collision, you'll want to compare the attributes of the player and enemy BoundingBoxes. So something like this...

 if( Player.BoundingBox.X = Enemy.BoundingBox.X && If( Player.BoundingBox.Y = Enemy.BoundingBox.Y )
 {
      //Oh noes!  The enemy and player are on top of eachother.
 }

The logic can get sort of complicated but you'll need to compare the distances between each BoundingBox and compare locations.

here's a really simple regex for that:

\W|_

and used as you need it (with a forward / slash delimiter).

preg_replace("/\W|_/", '', $string);

Test it here with this great tool that explains what the regex is doing:

http://www.regexr.com/

I think you are looking for $evalAsync http://docs.angularjs.org/api/ng.$rootScope.Scope#$evalAsync

There is exactly one reason why the following is preferred:

with open('filename.txt') as fp:
    for line in fp:
        print line

We are all spoiled by CPython's relatively deterministic reference-counting scheme for garbage collection. Other, hypothetical implementations of Python will not necessarily close the file "quickly enough" without the with block if they use some other scheme to reclaim memory.

In such an implementation, you might get a "too many files open" error from the OS if your code opens files faster than the garbage collector calls finalizers on orphaned file handles. The usual workaround is to trigger the GC immediately, but this is a nasty hack and it has to be done by every function that could encounter the error, including those in libraries. What a nightmare.

Or you could just use the with block.

Bonus Question

(Stop reading now if are only interested in the objective aspects of the question.)

Why isn't that included in the iterator protocol for file objects?

This is a subjective question about API design, so I have a subjective answer in two parts.

On a gut level, this feels wrong, because it makes iterator protocol do two separate things—iterate over lines and close the file handle—and it's often a bad idea to make a simple-looking function do two actions. In this case, it feels especially bad because iterators relate in a quasi-functional, value-based way to the contents of a file, but managing file handles is a completely separate task. Squashing both, invisibly, into one action, is surprising to humans who read the code and makes it more difficult to reason about program behavior.

Other languages have essentially come to the same conclusion. Haskell briefly flirted with so-called "lazy IO" which allows you to iterate over a file and have it automatically closed when you get to the end of the stream, but it's almost universally discouraged to use lazy IO in Haskell these days, and Haskell users have mostly moved to more explicit resource management like Conduit which behaves more like the with block in Python.

On a technical level, there are some things you may want to do with a file handle in Python which would not work as well if iteration closed the file handle. For example, suppose I need to iterate over the file twice:

with open('filename.txt') as fp:
    for line in fp:
        ...
    fp.seek(0)
    for line in fp:
        ...

While this is a less common use case, consider the fact that I might have just added the three lines of code at the bottom to an existing code base which originally had the top three lines. If iteration closed the file, I wouldn't be able to do that. So keeping iteration and resource management separate makes it easier to compose chunks of code into a larger, working Python program.

Composability is one of the most important usability features of a language or API.

Tried all the above, use the Firebase Assistant! It is the simplest way to solve this. First remove all the dependencies you added to the build.gradle (using the manual method) and then in Android Studio:

Click Tools > Firebase to open the Assistant window.

It really is as easy as that.

Ok, that is ?? NOT ?? the thousands repeat of add it to your Manifest, but an hint which base on this, but give you additional Benefit (and maybe some Background Info).

Android has a kind of overwriting functionality for the src-Directory.

By default, you have

/app/src/main

But you can add additional directories to overwrite your AndroidManifest.xml. Here is how it works:

• Create the Directory /app/src/debug
• Inside create the AndroidManifest.xml

Inside of this File, you don't have to put all the Rules inside, but only the ones you like to overwrite from your /app/src/main/AndroidManifest.xml

Here an Example how it looks like for the requested CLEARTEXT-Permission:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="com.yourappname">

    <application
            android:usesCleartextTraffic="true"
            android:name=".MainApplication"
            android:label="@string/app_name"
            android:icon="@mipmap/ic_launcher"
            android:allowBackup="false"
            android:theme="@style/AppTheme">
    </application>

</manifest>

With this knowledge it's now easy as 1,2,3 for you to overload your Permissions depending on your debug | main | release Enviroment.

The big benefit on it... you don't have debug-stuff in your production-Manifest and you keep an straight and easy maintainable structure

I had this problem and the suggestions above didn't help. What I found is that the add-migration reads the current state and creates a signature of the current model. You must modify your model before modifying. So the sequence is.

1. Modify model
2. run add-migration

I did the opposite and added the migration before modifying my model (which was empty, so I added the new columns) and then ran my code.

Hope this helps.

Exceptions are a good way to handle unexpected events in your application flow. RuntimeException are unchecked by the Compiler but you may prefer to use Exceptions that extend Exception Class to control the behaviour of your api clients as they are required to catch errors for them to compile. Also forms good documentation.

If want to achieve clean interface use inheritance to subclass the different types of exception your application has and then expose the parent exception.

The best way to set radiobuttons state in jquery:

HTML:

<input type="radio" name="color" value="orange" /> Orange 
<input type="radio" name="color" value="pink" /> Pink 
<input type="radio" name="color" value="black" /> Black
<input type="radio" name="color" value="pinkish purple" /> Pinkish Purple

Jquery (1.4+) code to pre-select one button :

var presetValue = "black";
$("[name=color]").filter("[value='"+presetValue+"']").attr("checked","checked");

In Jquery 1.6+ code the .prop() method is preferred :

var presetValue = "black";
$("[name=color]").filter("[value='"+presetValue+"']").prop("checked",true);

To unselect the buttons :

$("[name=color]").removeAttr("checked");

The << part is wrong, use < instead:

$ ./manage.py shell < myscript.py

You could also do:

$ ./manage.py shell
...
>>> execfile('myscript.py')

For python3 you would need to use

>>> exec(open('myscript.py').read())

I used it as singleton like:

public static void showSoftKeyboard(final Context context, final EditText editText) {
        try {
            editText.requestFocus();
            editText.postDelayed(
                    new Runnable() {
                        @Override
                        public void run() {
                            InputMethodManager keyboard = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
                            keyboard.showSoftInput(editText, 0);
                        }
                    }
                    , 200);
        } catch (NullPointerException npe) {
            npe.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

Use it in your activity like:

showSoftKeyboard(this, yourEditTextToFocus);

This error message happens either because your ProfileDto class is not registered in the JAXB Content, or the class using it does not use @XmlSeeAlso(ProfileDto.class) to make processable by JAXB.

About your comment:

I was under the impression the annotations was only needed when the referenced class was a sub-class.

No, they are also needed when not declared in the JAXB context or, for example, when the only class having a static reference to it has this reference annotated with @XmlTransient. I maintain a tutorial here.

If you want to add a dynamic class to your host element, you may combine your HostBinding with a getter as

@HostBinding('class') get class() {
    return aComponentVariable
}

Stackblitz demo at https://stackblitz.com/edit/angular-dynamic-hostbinding

Use setLocationRelativeTo(null)

This method has a special effect when you pass it a null. According to the Javadoc:

If the component is null, or the GraphicsConfiguration associated with this component is null, the window is placed in the center of the screen.

This should be done after setting the size or calling pack(), but before setting it visible, like this:

frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);

Your question is: are these not modules capable of declaring variables at global scope?

Answer: YES, they are "capable"

The only point is that references to global variables in ThisWorkbook or a Sheet module have to be fully qualified (i.e., referred to as ThisWorkbook.Global1, e.g.) References to global variables in a standard module have to be fully qualified only in case of ambiguity (e.g., if there is more than one standard module defining a variable with name Global1, and you mean to use it in a third module).

For instance, place in Sheet1 code

Public glob_sh1 As String

Sub test_sh1()
    Debug.Print (glob_mod)
    Debug.Print (ThisWorkbook.glob_this)
    Debug.Print (Sheet1.glob_sh1)
End Sub

place in ThisWorkbook code

Public glob_this As String

Sub test_this()
    Debug.Print (glob_mod)
    Debug.Print (ThisWorkbook.glob_this)
    Debug.Print (Sheet1.glob_sh1)
End Sub

and in a Standard Module code

Public glob_mod As String

Sub test_mod()
    glob_mod = "glob_mod"
    ThisWorkbook.glob_this = "glob_this"
    Sheet1.glob_sh1 = "glob_sh1"
    Debug.Print (glob_mod)
    Debug.Print (ThisWorkbook.glob_this)
    Debug.Print (Sheet1.glob_sh1)
End Sub

All three subs work fine.

PS1: This answer is based essentially on info from here. It is much worth reading (from the great Chip Pearson).

PS2: Your line Debug.Print ("Hello") will give you the compile error Invalid outside procedure.

PS3: You could (partly) check your code with Debug -> Compile VBAProject in the VB editor. All compile errors will pop.

PS4: Check also Put Excel-VBA code in module or sheet?.

PS5: You might be not able to declare a global variable in, say, Sheet1, and use it in code from other workbook (reading http://msdn.microsoft.com/en-us/library/office/gg264241%28v=office.15%29.aspx#sectionSection0; I did not test this point, so this issue is yet to be confirmed as such). But you do not mean to do that in your example, anyway.

PS6: There are several cases that lead to ambiguity in case of not fully qualifying global variables. You may tinker a little to find them. They are compile errors.

Expanded answer, was my first answer so excuse if there wasn’t enough detail before.

For Bootstrap 3.x I personally prefer CSS animations and I've been using animate.css & along with the Bootstrap Dropdown Javascript Hooks. Although it might not have the exactly effect you're after it's a pretty flexible approach.

Step 1: Add animate.css to your page with the head tags:

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/animate.css/3.4.0/animate.min.css">

Step 2: Use the standard Bootstrap HTML on the trigger:

<div class="dropdown">
  <button type="button" data-toggle="dropdown">Dropdown trigger</button>

  <ul class="dropdown-menu">
    ...
  </ul>
</div>

Step 3: Then add 2 custom data attributes to the dropdrop-menu element; data-dropdown-in for the in animation and data-dropdown-out for the out animation. These can be any animate.css effects like fadeIn or fadeOut

<ul class="dropdown-menu" data-dropdown-in="fadeIn" data-dropdown-out="fadeOut">
......
</ul>

Step 4: Next add the following Javascript to read the data-dropdown-in/out data attributes and react to the Bootstrap Javascript API hooks/events (http://getbootstrap.com/javascript/#dropdowns-events):

var dropdownSelectors = $('.dropdown, .dropup');

// Custom function to read dropdown data
// =========================
function dropdownEffectData(target) {
  // @todo - page level global?
  var effectInDefault = null,
      effectOutDefault = null;
  var dropdown = $(target),
      dropdownMenu = $('.dropdown-menu', target);
  var parentUl = dropdown.parents('ul.nav'); 

  // If parent is ul.nav allow global effect settings
  if (parentUl.size() > 0) {
    effectInDefault = parentUl.data('dropdown-in') || null;
    effectOutDefault = parentUl.data('dropdown-out') || null;
  }

  return {
    target:       target,
    dropdown:     dropdown,
    dropdownMenu: dropdownMenu,
    effectIn:     dropdownMenu.data('dropdown-in') || effectInDefault,
    effectOut:    dropdownMenu.data('dropdown-out') || effectOutDefault,  
  };
}

// Custom function to start effect (in or out)
// =========================
function dropdownEffectStart(data, effectToStart) {
  if (effectToStart) {
    data.dropdown.addClass('dropdown-animating');
    data.dropdownMenu.addClass('animated');
    data.dropdownMenu.addClass(effectToStart);    
  }
}

// Custom function to read when animation is over
// =========================
function dropdownEffectEnd(data, callbackFunc) {
  var animationEnd = 'webkitAnimationEnd mozAnimationEnd MSAnimationEnd oanimationend animationend';
  data.dropdown.one(animationEnd, function() {
    data.dropdown.removeClass('dropdown-animating');
    data.dropdownMenu.removeClass('animated');
    data.dropdownMenu.removeClass(data.effectIn);
    data.dropdownMenu.removeClass(data.effectOut);

    // Custom callback option, used to remove open class in out effect
    if(typeof callbackFunc == 'function'){
      callbackFunc();
    }
  });
}

// Bootstrap API hooks
// =========================
dropdownSelectors.on({
  "show.bs.dropdown": function () {
    // On show, start in effect
    var dropdown = dropdownEffectData(this);
    dropdownEffectStart(dropdown, dropdown.effectIn);
  },
  "shown.bs.dropdown": function () {
    // On shown, remove in effect once complete
    var dropdown = dropdownEffectData(this);
    if (dropdown.effectIn && dropdown.effectOut) {
      dropdownEffectEnd(dropdown, function() {}); 
    }
  },  
  "hide.bs.dropdown":  function(e) {
    // On hide, start out effect
    var dropdown = dropdownEffectData(this);
    if (dropdown.effectOut) {
      e.preventDefault();   
      dropdownEffectStart(dropdown, dropdown.effectOut);   
      dropdownEffectEnd(dropdown, function() {
        dropdown.dropdown.removeClass('open');
      }); 
    }    
  }, 
});

Step 5 (optional): If you want to speed up or alter the animation you can do so with CSS like the following:

.dropdown-menu.animated {
  /* Speed up animations */
  -webkit-animation-duration: 0.55s;
  animation-duration: 0.55s;
  -webkit-animation-timing-function: ease;
  animation-timing-function: ease;
}

Hope that’s helpful & this second write up has the level of detail that’s needed Tom

I got here looking for a solution for JavaScript displayed in the browser and although not directly related with a database...

In my case I copied and pasted some text I found on the internet into a JavaScript file and saved it with Windows Notepad.

When the page that uses that JavaScript file output the strings there were question marks (like the ones shown in the question) instead of the special characters like accented letters, etc.

I opened the file using Notepad++. Right after opening the file I saw that the character encoding was set as ANSI as you can see (mouse cursor on footer) in the following screenshot:

To solve the issue, click the Encoding menu in Notepad++ and select Encode in UTF-8. You should be good to go. :)

So, $HOME is what I need to modify.

However I have been unable to find where this mythical $HOME variable is set so I assumed it was a Linux system version of PATH or something.

Git 2.23 (Q3 2019) is quite explicit on how HOME is set.

See commit e12a955 (04 Jul 2019) by Karsten Blees (kblees).
^{(Merged by Junio C Hamano -- gitster -- in commit fc613d2, 19 Jul 2019)}

mingw: initialize HOME on startup

HOME initialization was historically duplicated in many different places, including /etc/profile, launch scripts such as git-bash.vbs and gitk.cmd, and (although slightly broken) in the git-wrapper.

Even unrelated projects such as GitExtensions and TortoiseGit need to implement the same logic to be able to call git directly.

Initialize HOME in Git's own startup code so that we can eventually retire all the duplicate initialization code.

Now, mingw.c includes the following code:

/* calculate HOME if not set */
if (!getenv("HOME")) {
    /*
     * try $HOMEDRIVE$HOMEPATH - the home share may be a network
     * location, thus also check if the path exists (i.e. is not
     * disconnected)
     */
    if ((tmp = getenv("HOMEDRIVE"))) {
        struct strbuf buf = STRBUF_INIT;
        strbuf_addstr(&buf, tmp);
        if ((tmp = getenv("HOMEPATH"))) {
            strbuf_addstr(&buf, tmp);
            if (is_directory(buf.buf))
                setenv("HOME", buf.buf, 1);
            else
                tmp = NULL; /* use $USERPROFILE */
        }
        strbuf_release(&buf);
    }
    /* use $USERPROFILE if the home share is not available */
    if (!tmp && (tmp = getenv("USERPROFILE")))
        setenv("HOME", tmp, 1);
}

public String datePicker(String object,String data){
    APP_LOGS.debug("selecting date");
    try{

        WebElement dateWidget = driver.findElement(By.xpath(OR.getProperty(object)));

        List<WebElement> rows = dateWidget.findElements(By.tagName("tr"));  
        List<WebElement> columns = dateWidget.findElements(By.tagName("td"));  

        for (WebElement cell: columns){
            if (cell.getText().equals(data)){
                cell.findElement(By.linkText(data)).click();
                break; 
            }
        }
    }catch(Exception e){
        return Constants.KEYWORD_FAIL+" -- Not able to select the date"+e.getMessage();
    }
    return Constants.KEYWORD_PASS;
}

Did you took a look at this? http://developer.yahoo.com/yui/history/

display: inline; is a display mode to use in a sentence. For instance, if you have a paragraph and want to highlight a single word you do:

<p>
    Pellentesque habitant morbi <em>tristique</em> senectus
    et netus et malesuada fames ac turpis egestas.
</p>

The <em> element has a display: inline; by default, because this tag is always used in a sentence. The <p> element has a display: block; by default, because it's neither a sentence nor in a sentence, it's a block of sentences.

An element with display: inline; cannot have a height or a width or a vertical margin. An element with display: block; can have a width, height and margin.
If you want to add a height to the <em> element, you need to set this element to display: inline-block;. Now you can add a height to the element and every other block style (the block part of inline-block), but it is placed in a sentence (the inline part of inline-block).

I'm not sure for JPA 1.0 but you can pass a Collection in JPA 2.0:

String qlString = "select item from Item item where item.name IN :names"; 
Query q = em.createQuery(qlString, Item.class);

List<String> names = Arrays.asList("foo", "bar");

q.setParameter("names", names);
List<Item> actual = q.getResultList();

assertNotNull(actual);
assertEquals(2, actual.size());

Tested with EclipseLInk. With Hibernate 3.5.1, you'll need to surround the parameter with parenthesis:

String qlString = "select item from Item item where item.name IN (:names)";

But this is a bug, the JPQL query in the previous sample is valid JPQL. See HHH-5126.

I found the best answer and it is working perfectly for me

just use this simple script in your link

<A HREF="javascript:history.go(0)">next page</A>

or the button click event

<INPUT TYPE="button" onClick="history.go(0)" VALUE="next page">

when you use this, you refresh your page first and then go to next page, when you return back it will be having the last refreshed state.

I have used it in a CAS login and gives me what I want. Hope it helps .......

details found from here

In PHP, passing by reference (&) is ... controversial. I recommend not using it unless you know why you need it and test the results.

I would recommend doing the following:

foreach ($fields as $key => $field) {
    if ($field['required'] && strlen($_POST[$field['name']]) <= 0) {
        $fields[$key]['value'] = "Some error";
    }
}

So basically use $field when you need the values, and $fields[$key] when you need to change the data.

This should work for you. Infact the one which you are thinking will also work:-

 .......
 DECLARE @returnvalue INT

 EXEC @returnvalue = SP_One
 .....

If you have already exported a .sql file, the best thing to do is to Find and Replace the following if you have them in your file:

• utf8mb4_0900_ai_ci to utf8_unicode_ci
• utf8mb4 to utf8
• utf8_unicode_520_ci to utf8_unicode_ci

It will replace utf8mb4_unicode_ci to utf8_unicode_ci. Now you go to your phpMyAdmin cPanel and set the DB collation to utf8_unicode_ci through Operations > Collation.

If you are exporting to a .sql, it's better to change the format on how you're exporting the file. Check out Evster's anwer (it's in the same page as this)

select COUNT(*)
from Monitor as m
    inner join Monitor_Request as mr on mr.Company_ID=m.Company_id
    group by m.Company_id
    having COUNT(m.Monitor_id)>=5

The return exits the current function, but the iterations keeps on, so you get the "next" item that skips the if and alerts the 4...

If you need to stop the looping, you should just use a plain for loop like so:

$('button').click(function () {
   var arr = [1, 2, 3, 4, 5];
   for(var i = 0; i < arr.length; i++) {
     var n = arr[i]; 
     if (n == 3) {
         break;
      }
      alert(n);
   })
})

You can read more about js break & continue here: http://www.w3schools.com/js/js_break.asp

You don't import scripts in Python you import modules. Some python modules are also scripts that you can run directly (they do some useful work at a module-level).

In general it is preferable to use absolute imports rather than relative imports.

toplevel_package/
+-- __init__.py
+-- moduleA.py
+-- subpackage
    +-- __init__.py
    +-- moduleB.py

In moduleB:

from toplevel_package import moduleA

If you'd like to run moduleB.py as a script then make sure that parent directory for toplevel_package is in your sys.path.

I have taken an empty dictionary as f and updated the values in f as name,password or balance are keys.

f=dict()
f.update(name=input(),password=input(),balance=input())
print(f)

It's Works

.ts -> pi = 3.1415

.html -> {{ pi | number : '1.0-2' }}

Ouput -> 3.14

1. if it has a decimal it only shows one
2. if it has two decimals it shows both

this works for me!!! thanks!!

$unixtime_to_date = date('jS F Y h:i:s A (T)', $unixtime);

This should work to.

Consider the case in which a service worker acts as an agnostic cache. Your only goal is serve the same resources that you would get from the network, but faster. Of course you can't ensure all the resources will be part of your origin (consider libraries served from CDNs, for instance). As the service worker has the potential of altering network responses, you need to guarantee you are not interested in the contents of the response, nor on its headers, nor even on the result. You're only interested on the response as a black box to possibly cache it and serve it faster.

This is what { mode: 'no-cors' } was made for.

Using str.format:

>>> array_alpha = [ 133, 53, 234, 241 ]
>>> print ''.join('{:02x}'.format(x) for x in array_alpha)
8535eaf1

or using format

>>> print ''.join(format(x, '02x') for x in array_alpha)
8535eaf1

Note: In the format statements, the 02 means it will pad with up to 2 leading 0s if necessary. This is important since [0x1, 0x1, 0x1] i.e. (0x010101) would be formatted to "111" instead of "010101"

or using bytearray with binascii.hexlify:

>>> import binascii
>>> binascii.hexlify(bytearray(array_alpha))
'8535eaf1'

Here is a benchmark of above methods in Python 3.6.1:

from timeit import timeit
import binascii

number = 10000

def using_str_format() -> str:
    return "".join("{:02x}".format(x) for x in test_obj)

def using_format() -> str:
    return "".join(format(x, "02x") for x in test_obj)

def using_hexlify() -> str:
    return binascii.hexlify(bytearray(test_obj)).decode('ascii')

def do_test():
    print("Testing with {}-byte {}:".format(len(test_obj), test_obj.__class__.__name__))
    if using_str_format() != using_format() != using_hexlify():
        raise RuntimeError("Results are not the same")

    print("Using str.format       -> " + str(timeit(using_str_format, number=number)))
    print("Using format           -> " + str(timeit(using_format, number=number)))
    print("Using binascii.hexlify -> " + str(timeit(using_hexlify, number=number)))

test_obj = bytes([i for i in range(255)])
do_test()

test_obj = bytearray([i for i in range(255)])
do_test()

Result:

Testing with 255-byte bytes:
Using str.format       -> 1.459474583090427
Using format           -> 1.5809937679100738
Using binascii.hexlify -> 0.014521426401399307
Testing with 255-byte bytearray:
Using str.format       -> 1.443447684109402
Using format           -> 1.5608712609513171
Using binascii.hexlify -> 0.014114164661833684

Methods using format do provide additional formatting options, as example separating numbers with spaces " ".join, commas ", ".join, upper-case printing "{:02X}".format(x)/format(x, "02X"), etc., but at a cost of great performance impact.

For Kotlin,

StringBuilder().appendLine("your text");

Though this is a java question, this is also the first google result for Kotlin, might come in handy.

How do you set up a shared team repository?

How to set up a normal repository is described here -- but how do you set up a team repository that everybody can pull and push from and to?

Using a shared NFS file system

Assuming your team already has for instance a shared group membership that can be used.

mkdir /your/share/folder/project.git
cd /your/share/folder/project.git
newgrp yourteamgroup # if necessary
git init --bare --shared

To start using this repository the easiest thing to do is start from a local repository you already have been using:

cd your/local/workspace/project
git remote add origin /your/share/folder/project.git
git push origin master

Others can now clone this and start working:

cd your/local/workspace
git clone /your/share/folder/project.git

Using SSH

Set up a user account on the target server. Whether you use an account with no password, an account with a password, or use authorized_keys really depend on your required level of security. Take a look at Configuring Git over SSH for some more information.

If all developers use the same account for accessing this shared repository, you do not need to use the --shared option as above.

After initing the repository in the same way as above, you do the initial push like this:

cd your/local/workspace/project
git remote add origin user@server:/path/to/project.git
git push origin master

See the similarity with the above? The only thing that might happen in addition is SSH asking for a password if the account has a password. If you get this prompt on an account without a password the SSH server probably has disabled PermitEmptyPasswords.

Cloning now looks like this:

cd your/local/workspace
git clone user@server:/path/to/project.git

Two ways I can think of are

var TestApp = React.createClass({
    getComponent: function(index) {
        $(this.getDOMNode()).find('li:nth-child(' + index + ')').css({
            'background-color': '#ccc'
        });
    },
    render: function() {
        return (
            <div>
              <ul>
                <li onClick={this.getComponent.bind(this, 1)}>Component 1</li>
                <li onClick={this.getComponent.bind(this, 2)}>Component 2</li>
                <li onClick={this.getComponent.bind(this, 3)}>Component 3</li>
              </ul>
            </div>
        );
    }
});
React.renderComponent(<TestApp /> , document.getElementById('soln1'));

This is my personal favorite.

        return (

        );

});

var TestApp2 = React.createClass({

        $(this.getDOMNode()).find('li:nth-child(' + index + ')').css({
            'background-color': '#ccc'
        });
    },
    render: function() {
        return (
            <div>

              <ListItem content="Component 1" />
              <ListItem content="Component 2" />
              <ListItem content="Component 3" />

function escapeRegExp(string) {
  return string.replace(/[.*+?^${}()|[\]\\]/g, '\\$&'); // $& means the whole matched string
}

Example

escapeRegExp("All of these should be escaped: \ ^ $ * + ? . ( ) | { } [ ]");

>>> "All of these should be escaped: \\ \^ \$ \* \+ \? \. \( \) \| \{ \} \[ \] "

(NOTE: the above is not the original answer; it was edited to show the one from MDN. This means it does not match what you will find in the code in the below npm, and does not match what is shown in the below long answer. The comments are also now confusing. My recommendation: use the above, or get it from MDN, and ignore the rest of this answer. -Darren,Nov 2019)

Install

Available on npm as escape-string-regexp

npm install --save escape-string-regexp

See MDN: Javascript Guide: Regular Expressions

Other symbols (~`!@# ...) MAY be escaped without consequence, but are not required to be.

Test Case: A typical url

>>> "\/path\/to\/resource\.html\?search=query"

The Long Answer

If you're going to use the function above at least link to this stack overflow post in your code's documentation so that it doesn't look like crazy hard-to-test voodoo.

var escapeRegExp;

(function () {
  // Referring to the table here:
  // https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/regexp
  // these characters should be escaped
  // \ ^ $ * + ? . ( ) | { } [ ]
  // These characters only have special meaning inside of brackets
  // they do not need to be escaped, but they MAY be escaped
  // without any adverse effects (to the best of my knowledge and casual testing)
  // : ! , = 
  // my test "~!@#$%^&*(){}[]`/=?+\|-_;:'\",<.>".match(/[\#]/g)

  var specials = [
        // order matters for these
          "-"
        , "["
        , "]"
        // order doesn't matter for any of these
        , "/"
        , "{"
        , "}"
        , "("
        , ")"
        , "*"
        , "+"
        , "?"
        , "."
        , "\\"
        , "^"
        , "$"
        , "|"
      ]

      // I choose to escape every character with '\'
      // even though only some strictly require it when inside of []
    , regex = RegExp('[' + specials.join('\\') + ']', 'g')
    ;

  escapeRegExp = function (str) {
    return str.replace(regex, "\\$&");
  };

  // test escapeRegExp("/path/to/res?search=this.that")
}());

By registering the class (specifically its CLSID) -- see e.g. here.

If your your list is dynamically generated with unknown number and your target is to always have last div in a new line set last div class to "col-xl-12" and remove other classes so it will always take a full row.

This is a copy of your code corrected so that last div always occupy a full row (I although removed unnecessary classes).

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet">_x000D_
<div class="grid">_x000D_
  <div class="row">_x000D_
    <div class="col-sm-3">Under me should be a DIV</div>_x000D_
    <div class="col-md-6 col-sm-5">Under me should be a DIV</div>_x000D_
    <div class="col-xl-12">I am the last DIV and I always take a full row for my self!!</div>_x000D_
  </div>_x000D_
</div>

If it is just stripping all HTML tags from a string, this works reliably with regex as well. Replace:

<[^>]*(>|$)

with the empty string, globally. Don't forget to normalize the string afterwards, replacing:

[\s\r\n]+

with a single space, and trimming the result. Optionally replace any HTML character entities back to the actual characters.

Note:

1. There is a limitation: HTML and XML allow > in attribute values. This solution will return broken markup when encountering such values.
2. The solution is technically safe, as in: The result will never contain anything that could be used to do cross site scripting or to break a page layout. It is just not very clean.
3. As with all things HTML and regex:
   Use a proper parser if you must get it right under all circumstances.

1. Enter into SETTING
2. Choose"Apps" & All
3. Select Google Services Framework
4. Clear data
5. Force stop

I don't use nested classes much, but I do use them now and then. Especially when I define some kind of data type, and I then want to define a STL functor designed for that data type.

For example, consider a generic Field class that has an ID number, a type code and a field name. If I want to search a vector of these Fields by either ID number or name, I might construct a functor to do so:

class Field
{
public:
  unsigned id_;
  string name_;
  unsigned type_;

  class match : public std::unary_function<bool, Field>
  {
  public:
    match(const string& name) : name_(name), has_name_(true) {};
    match(unsigned id) : id_(id), has_id_(true) {};
    bool operator()(const Field& rhs) const
    {
      bool ret = true;
      if( ret && has_id_ ) ret = id_ == rhs.id_;
      if( ret && has_name_ ) ret = name_ == rhs.name_;
      return ret;
    };
    private:
      unsigned id_;
      bool has_id_;
      string name_;
      bool has_name_;
  };
};

Then code that needs to search for these Fields can use the match scoped within the Field class itself:

vector<Field>::const_iterator it = find_if(fields.begin(), fields.end(), Field::match("FieldName"));

For Mac:

Quick Text Search: Shift + Cmd + L

All other search (like File Search, Git Search, Java Search etc): Ctrl + H

You can use NSTask. Here's an example that would run '/usr/bin/grep foo bar.txt'.

int pid = [[NSProcessInfo processInfo] processIdentifier];
NSPipe *pipe = [NSPipe pipe];
NSFileHandle *file = pipe.fileHandleForReading;

NSTask *task = [[NSTask alloc] init];
task.launchPath = @"/usr/bin/grep";
task.arguments = @[@"foo", @"bar.txt"];
task.standardOutput = pipe;

[task launch];

NSData *data = [file readDataToEndOfFile];
[file closeFile];

NSString *grepOutput = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];
NSLog (@"grep returned:\n%@", grepOutput);

NSPipe and NSFileHandle are used to redirect the standard output of the task.

For more detailed information on interacting with the operating system from within your Objective-C application, you can see this document on Apple's Development Center: Interacting with the Operating System.

Edit: Included fix for NSLog problem

If you are using NSTask to run a command-line utility via bash, then you need to include this magic line to keep NSLog working:

//The magic line that keeps your log where it belongs
task.standardOutput = pipe;

An explanation is here: https://web.archive.org/web/20141121094204/https://cocoadev.com/HowToPipeCommandsWithNSTask

You can set drawableLeft in the XML as suggested by marcos, but you might also want to set it programmatically - for example in response to an event. To do this use the method setCompoundDrawablesWithIntrincisBounds(int, int, int, int):

EditText editText = findViewById(R.id.myEditText);

// Set drawables for left, top, right, and bottom - send 0 for nothing
editTxt.setCompoundDrawablesWithIntrinsicBounds(R.drawable.myDrawable, 0, 0, 0);

Try this // html example

<span>&#10003;</span>

// css example

span {
  content: "\2713";
}

asprintf is not 100% standard, but it's available via the GNU and BSD standard C libraries, so you probably have it. It allocates the output, so you don't have to sit there and count characters.

char *hi="Hello";
char *ext = ".txt";
char *cat;

asprintf(&cat, "%s%s", hi, ext);

For those looking to add an item to a json collection

function save(item, path = './collection.json'){
    if (!fs.existsSync(path)) {
        fs.writeFile(path, JSON.stringify([item]));
    } else {
        var data = fs.readFileSync(path, 'utf8');  
        var list = (data.length) ? JSON.parse(data): [];
        if (list instanceof Array) list.push(item)
        else list = [item]  
        fs.writeFileSync(path, JSON.stringify(list));
    }
}

For this issue need to add the partition for date column values, If last partition 20201231245959, then inserting the 20210110245959 values, this issue will occurs.

For that need to add the 2021 partition into that table

ALTER TABLE TABLE_NAME ADD PARTITION PARTITION_NAME VALUES LESS THAN (TO_DATE('2021-12-31 24:59:59', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN')) NOCOMPRESS

You can find the execution time in second with a single function.

// ampersand is important thing here
function microSec( & $ms ) {
    if (\floatval( $ms ) == 0) {
        $ms = microtime( true );
    }
    else {
        $originalMs = $ms;
        $ms = 0;
        return microtime( true ) - $originalMs;
    }
}

// you don't have to define $ms variable. just function needs
// it to calculate the difference.
microSec($ms);
sleep(10);
echo microSec($ms) . " seconds"; // 10 seconds

for( $i = 0; $i < 10; $i++) {
    // you can use same variable everytime without assign a value
    microSec($ms);
    sleep(1);
    echo microSec($ms) . " seconds"; // 1 second
}

for( $i = 0; $i < 10; $i++) {
    // also you can use temp or useless variables
    microSec($xyzabc);
    sleep(1);
    echo microSec($xyzabc) . " seconds"; // 1 second
}

The outfile should be in binary mode.

outFile = open('output.xml', 'wb')

Connect with SSH and follow these instructions to install Node on a shared hosting

In short you first install NVM, then you install the Node version of your choice with NVM.

wget -qO- https://cdn.rawgit.com/creationix/nvm/master/install.sh | bash

Your restart your shell (close and reopen your sessions). Then you

nvm install stable

to install the latest stable version for example. You can install any version of your choice. Check node --version for the node version you are currently using and nvm list to see what you've installed.

In bonus you can switch version very easily (nvm use <version>)

There's no need of PHP or whichever tricky workaround if you have SSH.

Similar to yebmouxing I could not the

 xhr.getResponseHeader('Set-Cookie');

method to work. It would only return null even if I had set HTTPOnly to false on my server.

I too wrote a simple js helper function to grab the cookies from the document. This function is very basic and only works if you know the additional info (lifespan, domain, path, etc. etc.) to add yourself:

function getCookie(cookieName){
  var cookieArray = document.cookie.split(';');
  for(var i=0; i<cookieArray.length; i++){
    var cookie = cookieArray[i];
    while (cookie.charAt(0)==' '){
      cookie = cookie.substring(1);
    }
    cookieHalves = cookie.split('=');
    if(cookieHalves[0]== cookieName){
      return cookieHalves[1];
    }
  }
  return "";
}

Try this, this works for my code name is a String:

cursor = rdb.query(true, TABLE_PROFILE, new String[] { ID,
    REMOTEID, FIRSTNAME, LASTNAME, EMAIL, GENDER, AGE, DOB,
    ROLEID, NATIONALID, URL, IMAGEURL },                    
    LASTNAME + " like ?", new String[]{ name+"%" }, null, null, null, null);

Many people have mentioned DecimalFormat. But you can also use printf if you have a recent version of Java:

System.out.printf("%1.2f", 3.14159D);

See the docs on the Formatter for more information about the printf format string.

You may use line-height on div1 as below:

<div id="div1" style="line-height:0px;">
    <div></div><div></div><div></div><br/><div></div><div></div><div></div>
</div>

See this: http://jsfiddle.net/wCpU8/

Like this:

$(document).ready(function ()
{
    document.title = "Hello World!";
});

Be sure to set a default-title if you want your site to be properly indexed by search-engines.

A little tip:

$(function ()
{
    // this is a shorthand for the whole document-ready thing
    // In my opinion, it's more readable 
});

You can use dijkstra's algorithm with negative edges not including negative cycle, but you must allow a vertex can be visited multiple times and that version will lose it's fast time complexity.

In that case practically I've seen it's better to use SPFA algorithm which have normal queue and can handle negative edges.

I have a library that is doing exactly you need.

Some time ago I had wrote simple and fast enough library for work with CSV files. You can find it by the following link: https://github.com/ukushu/DataExporter

It works with CSV like with 2 dimensions array. Exactly like you need.

As example, in case of you need all of values of 3rd row only you need is to write:

Csv csv = new Csv();

csv.FileOpen("c:\\file1.csv");

var allValuesOf3rdRow = csv.Rows[2];

or to read 2nd cell of

var value = csv.Rows[2][1];

This will convert to a numeric value without the need to cast or specify length or digits:

STRING_COL+0.0

If your column is an INT, can leave off the .0 to avoid decimals:

STRING_COL+0

O(1) always execute in the same time regardless of dataset n. An example of O(1) would be an ArrayList accessing its element with index.

O(n) also known as Linear Order, the performance will grow linearly and in direct proportion to the size of the input data. An example of O(n) would be an ArrayList insertion and deletion at random position. As each subsequent insertion/deletion at random position will cause the elements in the ArrayList to shift left right of its internal array in order to maintain its linear structure, not to mention about the creation of a new arrays and the copying of elements from the old to new array which takes up expensive processing time hence, detriment the performance.

For example this simple Makefile should be sufficient:

CC=gcc 
CFLAGS=-Wall

all: program
program: program.o
program.o: program.c program.h headers.h

clean:
    rm -f program program.o
run: program
    ./program

Note there must be <tab> on the next line after clean and run, not spaces.

UPDATE Comments below applied

I tried to make this as simple as possible in Java. This makes an integer array of 100 variables and fill it with integers between 0 and 10 using only three lines of code. You can easily change the bounds of the random number too!

int RandNumbers[]=new int[100];
for (int i=0;i<RandNumbers.length;i++)
    RandNumbers[i]=ThreadLocalRandom.current().nextInt(0,10);

When you create a NetBeans project from existing sources, NetBeans uses the same directory to add its own files: a netbeans folder with .proj files.

Solution: delete the netbeans folder and restart the IDE. Opening a new project should now work.

replace your image tag with

<img src="http://localhost:6054/wp-content/themes/BLANK-Theme/images/material/images.jpg" alt="the-buzz-img3"  style="width:640px;height:360px" />

use style attribute and make sure there is no css class for image which set image height and width

lastInsertId() only work after the INSERT query.

Correct:

$stmt = $this->conn->prepare("INSERT INTO users(userName,userEmail,userPass) 
                              VALUES(?,?,?);");
$sonuc = $stmt->execute([$username,$email,$pass]);
$LAST_ID = $this->conn->lastInsertId();

Incorrect:

$stmt = $this->conn->prepare("SELECT * FROM users");
$sonuc = $stmt->execute();
$LAST_ID = $this->conn->lastInsertId(); //always return string(1)=0

Make a toggle function in the respective scope to grey out the link.

First,create the following CSS classes in your .css file.

.disabled {
    pointer-events: none;
    cursor: default;
}

.enabled {
    pointer-events: visible;
    cursor: auto;
}

Add a $scope.state and $scope.toggle variable. Edit your controller in the JS file like:

    $scope.state='on';
    $scope.toggle='enabled';
    $scope.changeState = function () {
                $scope.state = $scope.state === 'on' ? 'off' : 'on';
                $scope.toggleEdit();
            };
    $scope.toggleEdit = function () {
            if ($scope.state === 'on')
                $scope.toggle = 'enabled';
            else
                $scope.toggle = 'disabled';
        };

Now,in the HTML a tags edit as:

<a href="#" ng-click="create()" class="{{toggle}}">CREATE</a><br/>
<a href="#" ng-click="edit()" class="{{toggle}}">EDIT</a><br/>
<a href="#" ng-click="delete()" class="{{toggle}}">DELETE</a>

To avoid the problem of the link disabling itself, change the DOM CSS class at the end of the function.

document.getElementById("create").className = "enabled";

Solution

To see the option for USB debugging mode in Nexus 4 or Android 4.2 or higher OS, do the following:

• Open up your device’s “Settings”. This can be done by pressing the Menu button while on your home screen and tapping “System settings”
• Now scroll to the bottom and tap “About phone” or “About tablet”.
• At the “About” screen, scroll to the bottom and tap on “Build number” seven times.
  • Make sure you tap seven times. If you see a “Not need, you are already a developer!” message pop up, then you know you have done it correctly.

Done! By tapping on “Build number” seven times, you have unlocked USB debugging mode on Android 4.2 and higher. You can now enable/disable it whenever you desire by going to “Settings” -> “Developer Options” -> “Debugging” ->” USB debugging”.

CONCLUSION

That was easy. The best part is you only have to do the tap-build-number-seven-times once. After you do it once, USB debugging has been unlocked and you can enable or disable at your leisure. Please restart after done these steps.

How about

List<object> collection = new List<object>((IEnumerable)myObject);

Emacs backup/auto-save files can be very helpful. But these features are confusing.

Backup files

Backup files have tildes (~ or ~9~) at the end and shall be written to the user home directory. When make-backup-files is non-nil Emacs automatically creates a backup of the original file the first time the file is saved from a buffer. If you're editing a new file Emacs will create a backup the second time you save the file.

No matter how many times you save the file the backup remains unchanged. If you kill the buffer and then visit the file again, or the next time you start a new Emacs session, a new backup file will be made. The new backup reflects the file's content after reopened, or at the start of editing sessions. But an existing backup is never touched again. Therefore I find it useful to created numbered backups (see the configuration below).

To create backups explicitly use save-buffer (C-x C-s) with prefix arguments.

diff-backup and dired-diff-backup compares a file with its backup or vice versa. But there is no function to restore backup files. For example, under Windows, to restore a backup file

C:\Users\USERNAME\.emacs.d\backups\!drive_c!Users!USERNAME!.emacs.el.~7~

it has to be manually copied as

C:\Users\USERNAME\.emacs.el

Auto-save files

Auto-save files use hashmarks (#) and shall be written locally within the project directory (along with the actual files). The reason is that auto-save files are just temporary files that Emacs creates until a file is saved again (like with hurrying obedience).

• Before the user presses C-x C-s (save-buffer) to save a file Emacs auto-saves files - based on counting keystrokes (auto-save-interval) or when you stop typing (auto-save-timeout).
• Emacs also auto-saves whenever it crashes, including killing the Emacs job with a shell command.

When the user saves the file, the auto-saved version is deleted. But when the user exits the file without saving it, Emacs or the X session crashes, the auto-saved files still exist.

Use revert-buffer or recover-file to restore auto-save files. Note that Emacs records interrupted sessions for later recovery in files named ~/.emacs.d/auto-save-list. The recover-session function will use this information.

The preferred method to recover from an auto-saved filed is M-x revert-buffer RET. Emacs will ask either "Buffer has been auto-saved recently. Revert from auto-save file?" or "Revert buffer from file FILENAME?". In case of the latter there is no auto-save file. For example, because you have saved before typing another auto-save-intervall keystrokes, in which case Emacs had deleted the auto-save file.

Auto-save is nowadays disabled by default because it can slow down editing when connected to a slow machine, and because many files contain sensitive data.

Configuration

Here is a configuration that IMHO works best:

(defvar --backup-directory (concat user-emacs-directory "backups"))
(if (not (file-exists-p --backup-directory))
        (make-directory --backup-directory t))
(setq backup-directory-alist `(("." . ,--backup-directory)))
(setq make-backup-files t               ; backup of a file the first time it is saved.
      backup-by-copying t               ; don't clobber symlinks
      version-control t                 ; version numbers for backup files
      delete-old-versions t             ; delete excess backup files silently
      delete-by-moving-to-trash t
      kept-old-versions 6               ; oldest versions to keep when a new numbered backup is made (default: 2)
      kept-new-versions 9               ; newest versions to keep when a new numbered backup is made (default: 2)
      auto-save-default t               ; auto-save every buffer that visits a file
      auto-save-timeout 20              ; number of seconds idle time before auto-save (default: 30)
      auto-save-interval 200            ; number of keystrokes between auto-saves (default: 300)
      )

Sensitive data

Another problem is that you don't want to have Emacs spread copies of files with sensitive data. Use this mode on a per-file basis. As this is a minor mode, for my purposes I renamed it sensitive-minor-mode.

To enable it for all .vcf and .gpg files, in your .emacs use something like:

(setq auto-mode-alist
      (append
       (list
        '("\\.\\(vcf\\|gpg\\)$" . sensitive-minor-mode)
        )
       auto-mode-alist))

Alternatively, to protect only some files, like some .txt files, use a line like

// -*-mode:asciidoc; mode:sensitive-minor; fill-column:132-*-

in the file.

The key lies in when you create the project in eclipse.

First step, you create the Java project in eclipse. Right click on the project and choose Team > Share>Git.

In the Configure Git Repository dialog, ensure that you select the option to create the Repository in the parent folder of the project.. Then you can push to github.

N.B: Eclipse will give you a warning about putting git repositories in your workspace. So when you create your project, set your project directory outside the default workspace.

>>> test = "have it break."
>>> selectiveEscape = "Print percent %% in sentence and not %s" % test
>>> print selectiveEscape
Print percent % in sentence and not have it break.

db2 'describe table "SCHEMA_NAME"."TBL_NAME"'

You add your ActionListener twice to button. So correct your code for button2 to

  JButton button2 = new JButton("hello agin2");
  panel.add(button2);
  button2.addActionListener (new Action2());//note the button2 here instead of button

Furthermore, perform your Swing operations on the correct thread by using EventQueue.invokeLater

Where is it pushed on?

esp - 4. More precisely:

• esp gets subtracted by 4
• the value is pushed to esp

pop reverses this.

The System V ABI tells Linux to make rsp point to a sensible stack location when the program starts running: What is default register state when program launches (asm, linux)? which is what you should usually use.

How can you push a register?

Minimal GNU GAS example:

.data
    /* .long takes 4 bytes each. */
    val1:
        /* Store bytes 0x 01 00 00 00 here. */
        .long 1
    val2:
        /* 0x 02 00 00 00 */
        .long 2
.text
    /* Make esp point to the address of val2.
     * Unusual, but totally possible. */
    mov $val2, %esp

    /* eax = 3 */
    mov $3, %ea 

    push %eax
    /*
    Outcome:
    - esp == val1
    - val1 == 3
    esp was changed to point to val1,
    and then val1 was modified.
    */

    pop %ebx
    /*
    Outcome:
    - esp == &val2
    - ebx == 3
    Inverses push: ebx gets the value of val1 (first)
    and then esp is increased back to point to val2.
    */

The above on GitHub with runnable assertions.

Why is this needed?

It is true that those instructions could be easily implemented via mov, add and sub.

They reason they exist, is that those combinations of instructions are so frequent, that Intel decided to provide them for us.

The reason why those combinations are so frequent, is that they make it easy to save and restore the values of registers to memory temporarily so they don't get overwritten.

To understand the problem, try compiling some C code by hand.

A major difficulty, is to decide where each variable will be stored.

Ideally, all variables would fit into registers, which is the fastest memory to access (currently about 100x faster than RAM).

But of course, we can easily have more variables than registers, specially for the arguments of nested functions, so the only solution is to write to memory.

We could write to any memory address, but since the local variables and arguments of function calls and returns fit into a nice stack pattern, which prevents memory fragmentation, that is the best way to deal with it. Compare that with the insanity of writing a heap allocator.

Then we let compilers optimize the register allocation for us, since that is NP complete, and one of the hardest parts of writing a compiler. This problem is called register allocation, and it is isomorphic to graph coloring.

When the compiler's allocator is forced to store things in memory instead of just registers, that is known as a spill.

Does this boil down to a single processor instruction or is it more complex?

All we know for sure is that Intel documents a push and a pop instruction, so they are one instruction in that sense.

Internally, it could be expanded to multiple microcodes, one to modify esp and one to do the memory IO, and take multiple cycles.

But it is also possible that a single push is faster than an equivalent combination of other instructions, since it is more specific.

This is mostly un(der)documented:

• Peter Cordes mentions that techniques described at http://agner.org/optimize/microarchitecture.pdf suggest that push and pop take one single micro operation.
• Johan mentions that since the Pentium M Intel uses a "stack engine", which stores precomputed esp+regsize and esp-regsize values, allowing push and pop to execute in a single uop. Also mentioned at: https://en.wikipedia.org/wiki/Stack_register
• What is Intel microcode?
• https://security.stackexchange.com/questions/29730/processor-microcode-manipulation-to-change-opcodes
• How many CPU cycles are needed for each assembly instruction?

best way using Object.keys();

example for getting multi variables names in global scope

// multi varibles for testing
var x = 5 , b = true , m = 6 , v = "str";

// pass all varibles you want in object
function getVarsNames(v = {}){
    // getting keys or names !
    let names = Object.keys(v);
    // return array has real names of varibles 
    return names;
}

//testing if that work or not 
let VarsNames = getVarsNames({x , b , m , v});

console.log(VarsNames); // output is array [x , b , m , v]

2. Running commands to configure $PATH - note though that it didn't work for me. https://postgresapp.com/documentation/cli-tools.html

3. Manually add it to the .bash_profile document:

   cd  # to get to your home folder
   open .bash_profile  # to open your bash_profile
   

   In your bash profile add:

   # Postgres
   export PATH=/Applications/Postgres.app/Contents/Versions/latest/bin
   

   Save the file. Restart the terminal. Type 'psql'. Done.

Take a look at Job Control on UNIX systems

If you don't have control of your shell, simply hitting ctrl + C should stop the process. If that doesn't work, you can try ctrl + Z and using the jobs and kill -9 %<job #> to kill it. The '-9' is a type of signal. You can man kill to see a list of signals.

When you create more than one instance of MyClass , you will still only have only one instance of publicMethod in memory but in case of privilegedMethod you will end up creating lots of instances and staticMethod has no relationship with an object instance.

That's why prototypes save memory.

Also, if you change the parent object's properties, is the child's corresponding property hasn't been changed, it'll be updated.

Using android studio to generate signed apk for react's android project is also a good and easy option , open react's android project in android studio and generate keystroke and signed apk.

Here's how you could use different methods to do selective column slicing, including selective label based, index based and the selective ranges based column slicing.

In [37]: import pandas as pd    
In [38]: import numpy as np
In [43]: df = pd.DataFrame(np.random.rand(4,7), columns = list('abcdefg'))

In [44]: df
Out[44]: 
          a         b         c         d         e         f         g
0  0.409038  0.745497  0.890767  0.945890  0.014655  0.458070  0.786633

In [45]: df.loc[:, ["a", "b", "c"]] ## label based selective column slicing 
Out[45]: 
          a         b         c
0  0.409038  0.745497  0.890767
1  0.570642  0.181552  0.794599
2  0.568440  0.501638  0.186635
3  0.679125  0.642817  0.697628

In [46]: df.loc[:, "a":"c"] ## label based column ranges slicing 
Out[46]: 
          a         b         c
0  0.409038  0.745497  0.890767

3  0.679125  0.642817  0.697628

In [47]: df.iloc[:, 0:3] ## index based column ranges slicing 
Out[47]: 
          a         b         c
0  0.409038  0.745497  0.890767

3  0.679125  0.642817  0.697628

### with 2 different column ranges, index based slicing: 
In [49]: df[df.columns[0:1].tolist() + df.columns[1:3].tolist()]
Out[49]: 
          a         b         c
0  0.409038  0.745497  0.890767
1  0.570642  0.181552  0.794599
2  0.568440  0.501638  0.186635
3  0.679125  0.642817  0.697628

This is very useful to avoid errors when accessing properties of null or undefined objects.

null to undefined object

const obj = null;
const newObj = obj || undefined;
// newObj = undefined

undefined to empty object

const obj; 
const newObj = obj || {};
// newObj = {}     
// newObj.prop = undefined, but no error here

null to empty object

const obj = null;
const newObj = obj || {};
// newObj = {}  
// newObj.prop = undefined, but no error here

2008 Answer The "Official" Java API for this is now JAXB - Java API for XML Binding. See Tutorial by Oracle. The reference implementation lives at http://jaxb.java.net/

2018 Update Note that the Java EE and CORBA Modules are deprecated in SE in JDK9 and to be removed from SE in JDK11. Therefore, to use JAXB it will either need to be in your existing enterprise class environment bundled by your e.g. app server, or you will need to bring it in manually.

I had the same problem today. Try it!

sudo chown -R  [yourgroup]  /home/[youruser]/.composer/cache/repo/https---packagist.org/


sudo chown -R  [yourgroup]   /home/[youruser]/.composer/cache/files/

Use -> when you have a pointer. Use . when you have structure (class).

When you want to point attribute that belongs to structure use .:

structure.attribute

When you want to point to an attribute that has reference to memory by pointer use -> :

pointer->method;

or same as:

(*pointer).method

write this command in your terminal :

composer update

Interpolate:

body
    height: calc(100% - #{$body_padding})

For this case, border-box would also suffice:

body
    box-sizing: border-box
    height: 100%
    padding-top: $body_padding

This error happens because your list lstpp is empty (Nothing at index 0). So either there is a bug in your getResult() function, or the empty list is normal and you need to handle this case (By checking the size of the list before, or catching the exception).

In Eclipse, it is necessary to create a separate project for google play services and reference it as a lib from your Android project instead of simply adding the jar to it. In my computer I have imported the google play services Eclipse project directly from D:\adt-bundle-windows-x86-20130219\sdk\extras\google\google_play_services\libproject\google-play-services_lib and set it to Lib project so I could reference it from my Android project.

Since this is a common piece of functionality it's a good idea to write a directive for this. In fact, someone already did that and open sourced it. I used editablespan library in one of my projects and it worked perfectly, highly recommended.

JAVACMD is an Ant specific environment variable. Ant doc says:

JAVACMD—full path of the Java executable. Use this to invoke a different JVM than JAVA_HOME/bin/java(.exe).

So, if your java.exe full path is: C:\Program Files\Java\jdk1.8.0_211\bin\java.exe, create a new environment variable called JAVACMD and set its value to the mentioned path (including \java.exe). Note that you need to close and reopen your terminal (cmd, Powershell, etc) so the new environment variable takes effect.

Using the hyperref package, you could also declare a new command by using \newcommand{\secref}[1]{\autoref{#1}. \nameref{#1}} in the pre-amble. Placing \secref{section:my} in the text generates: 1. My section.

Question: Is there a simple way to do this in the current release of Python?

Answer: There is no simple (direct) way to do this in the current release of Python.

Reference: Please refer to docs.python.org/2/library/datetime.html, section 8.1.2. timedelta Objects. As we may understand from that, we cannot increment month directly since it is not a uniform time unit.

Plus: If you want first day -> first day and last day -> last day mapping you should handle that separately for different months.

i solve by way nuget. the first you install nuget. the second you use.
illustration follow:

third : Check to see if this is the latest version by looking at the "Version" property.

The finaly : you check project have latest version again.

I found a Problem with marquee that it can't be used for short strings(As its function is only to Show Long strings).

I suggest Use Webview If you want to move short strings horizontally. Main_Activity.java Code:`

        WebView webView;

        webView = (WebView)findViewById(R.id.web);


        String summary = "<html><FONT color='#fdb728' FACE='courier'><marquee behavior='scroll' direction='left' scrollamount=10>"
                + "Hello Droid" + "</marquee></FONT></html>";

        webView.loadData(summary, "text/html", "utf-8"); // Set focus to the textview
`

main_activity.xml code:

<WebView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/web"
        ></WebView>

Onclick Function Jquery

$('#selector').click(function(){ //Your Functionality });

It is possible to insert an image in a Google Spreadsheet using Google Apps Script. However, the image should have been hosted publicly over internet. At present, it is not possible to insert private images from Google Drive.

You can use following code to insert an image through script.

  function insertImageOnSpreadsheet() {
  var SPREADSHEET_URL = 'INSERT_SPREADSHEET_URL_HERE';
  // Name of the specific sheet in the spreadsheet.
  var SHEET_NAME = 'INSERT_SHEET_NAME_HERE';

  var ss = SpreadsheetApp.openByUrl(SPREADSHEET_URL);
  var sheet = ss.getSheetByName(SHEET_NAME);

  var response = UrlFetchApp.fetch(
      'https://developers.google.com/adwords/scripts/images/reports.png');
  var binaryData = response.getContent();

  // Insert the image in cell A1.
  var blob = Utilities.newBlob(binaryData, 'image/png', 'MyImageName');
  sheet.insertImage(blob, 1, 1);
}

Above example has been copied from this link. Check noogui's reply for details.

In case you need to insert image from Google Drive, please check this link for current updates.

Long story short: Don't use FileInputStream as a parameter or variable type. Use the abstract base class, in this case InputStream instead.

You need an additional library for code coverage, and you are going to be blown away by how powerful and easy istanbul is. Try the following, after you get your mocha tests to pass:

npm install nyc

Now, simply place the command nyc in front of your existing test command, for example:

{
  "scripts": {
    "test": "nyc mocha"
  }
}

Using the MouseEvent api, to check the pressed button, if any:

document.addEventListener('mousedown', (e) => console.log(e.buttons))

Return:

A number representing one or more buttons. For more than one button pressed simultaneously, the values are combined (e.g., 3 is primary + secondary).

0 : No button or un-initialized
1 : Primary button (usually the left button)
2 : Secondary button (usually the right button)
4 : Auxilary button (usually the mouse wheel button or middle button)
8 : 4th button (typically the "Browser Back" button)
16 : 5th button (typically the "Browser Forward" button)

If none of the above works, try adding

@XmlRootElement(name="Group") to the Group classs.

On Fedora 21

$ vi /etc/my.cnf

Add follow:

[client]
default-character-set=utf8

[mysql]

Save and exit.

Final remember restart service mysqld with service mysqld restart.

I would use something like x.substring(0, x.lastIndexOf('.')). If you're going for performance, don't go for javascript at all :-p No, one more statement really doesn't matter for 99.99999% of all purposes.

Here is the answer.

System.exit(0);// normal termination - Successful - zero
System.exit(-1);//Exit with some Error
System.exit(1);//one or any positive integer // exit with some Information message

The existing answers are true as of C# <=7.2. However, there is a C# language feature request (tied to a corefx feature request) to allow the following;

public class MyGeneric<TEnum> where TEnum : System.Enum
{ }

At time of writing, the feature is "In discussion" at the Language Development Meetings.

EDIT

As per nawfal's info, this is being introduced in C# 7.3.

EDIT 2

This is now in C# 7.3 forward (release notes)

Sample;

public static Dictionary<int, string> EnumNamedValues<T>()
    where T : System.Enum
{
    var result = new Dictionary<int, string>();
    var values = Enum.GetValues(typeof(T));

    foreach (int item in values)
        result.Add(item, Enum.GetName(typeof(T), item));
    return result;
}
