is php sha256 safe today (may 2019)?

help you fix your problem There is no need to use the hash() method and is extremely pointless creating your own hashing techniques when PHP has its own built in functions to achieve this.
password_hash() and password_verify.
code :
if(
   isset(($username = $_POST['username'])) &&
   isset(($password = $_POST['password']))
) {
    ($con->prepare('INSERT INTO tbl_users (username, password) VALUES (? ,?)'))
         ->execute(array(
             $username,
             password_hash(base64_encode($password), PASSWORD_BCRYPT)
         ));
}

Hope this helps The page says that the 256bit signature is derived from a payload (what facebook is signing) + your 128 bit salt.
So yes, it sounds like correct usage.

MDX for get after 6 month last date from today. ex, 2019-02-28

it fixes the issue You should use DATEADD("dd", - 1, DATEADD("M", 7, GETDATE())) for get last day of the month. Your query gives the last day of the current month.
code :
(DT_WSTR, 10) DATEPART("YYYY", DATEADD("M", 6, GETDATE())) 
   + "-" + RIGHT( "0" + (DT_WSTR, 10) DATEPART("MM" , DATEADD("M", 6, GETDATE())), 2)   
   + "-" + RIGHT( "0" + (DT_STR, 6 ,1252) DATEPART("DD", DATEADD("dd", - day(getdate()), DATEADD("M", 7, GETDATE()))), 2)
How to find a Future Date in Java(say two months from today) in 24 February 2019 format

How to find a Future Date in Java(say two months from today) in 24 February 2019 format

it should still fix some issue Try using the DateTimeFormatter class introduced in Java 8, avoid using the SimpleDateFormat :
code :
public static void main(String[] args) {
     LocalDate futureDate = LocalDate.now().plusMonths(2);
     DateTimeFormatter formatter = DateTimeFormatter.ofPattern("dd MMMM yyyy");
     String dateStr = futureDate.format(formatter);
     System.out.println(dateStr);
}

Any of those help The datetime object you are passing to Airflow isn't timezone aware. Airflow uses UTC internally. The naive datetime object you are passing to Airflow may not be aligned with the scheduler's notion of time and this could be why the DAG isn't being scheduled to run midnight "today" (2019-12-18).
Instead of passing a naive datetime object like this:
code :
'start_date': dt.datetime(2019, 12, 18, 10, 00, 00)
import pendulum

...
'start_date': pendulum.datetime(year=2019, month=12, day=10).astimezone('YOUR TIMEZONE'), # See list of tz database time zones here -> https://en.wikipedia.org/wiki/List_of_tz_database_time_zones

Date column is varchar how to select data until today from 01-01-2019

fixed the issue. Will look into that further I have a problem with fetch data. Date is saved in VARCHAR, which means it will string. I want to select data from 01-01-2019 to today in my table. So I have problem in where class condition. , A query like this, then:
code :
SELECT * 
FROM holidays 
WHERE STR_TO_DATE(holiday_date, '%d-%m-%Y') BETWEEN STR_TO_DATE('01-01-2019', '%d-%m-%Y') AND NOW()
ORDER BY STR_TO_DATE(holiday_date, '%d-%m-%Y') asc
