How to check if someone has cheated on "Likes" ?

Hello,

I'm believing someone is cheating on "Likes". There is a paid competition, and who has most "Likes" wins (outside Facebook, but integrated with a Facebook API inside an HTML5 page). It goes that an user, who has about 140 friends right now, and had about 500 "Likes" on 9AM on a day, increased to about 5,000 "Likes" on 11AM that day. This is unbelievable, as it's impossible that he had so many people to tell to like in just 2 hours!

This is breaking the competition's rules; how to…

database design – MySQL: Is it best practice to check whether some column is NULL by `NOT ISNULL(column_name)`?

Given the following schema, my question is that since I have already added the NOT NULL to IsBanned, would I have to check whether it is not null using the syntax NOT ISNULL(IsBanned)? And what’s the best practice to do the same if I didn’t add NOT NULL?

CREATE TABLE Viewer (
    AccountID varchar(25),
    IsBanned boolean                NOT NULL
                                    DEFAULT 0,
    ...
    CHECK                           (NOT ISNULL(isBanned)),
);

As you can see I

customs and immigration – FRA airport: Where to pay for my pet in cabin? How do you reach check in after arriving at FRA?

Please be aware that my question stems from a basic lack of knowledge of airports.

First of all: I’m moving to Berlin from Austin, and I’m doing so with my cat in cabin. The flights will be Austin-Washington, Washington-Frankfurt, Frankfurt-Berlin. The first flights are operated by United and then Frankfurt-Berlin is by Lufthansa. For the record Washington-Frankfurt and Frankfurt-Berlin all happen in the A/Z hallway of the Frankfurt airport in the below map.

I’ve already paid for my cat in cabin with United. But with Lufthansa you need to pay at the airport. My question is where? The lady at customer service wasn’t very helpful.

I’ve been told I pay at check in. My confusion is how do I get there without exiting the airport? I know this sounds dumb but I’m used to American airports where you park outside then come in to check in then go into security then to where all the gates are. When I arrive at Frankfurt aren’t I where all the gates are? Don’t I just walk from a gate with A to a gate with Z?

I guess the solution to this is that when I arrive from Frankfurt from an international flight, I go through immigration then this dumps me out at the terminal entrance where I check in, then go into security then go to the gate for Frankfurt-Berlin. But this doesn’t make any sense according to the map because through which way am I being dumped at the terminal entrance if Washington-Berlin and Frankfurt-Berlin occur in A/Z.

Feel free to answer whatever section of this post. I think the best way for you to answer is to just tell me how this will all happen as in “you arrive then go from here to here then there blah blah” and I’d appreciate it if you refer to the map below, if possible.

A quick subquestion to all this: Do I need to walk into the “I have something to declare” lane if I have a cat with me?

Thank you!!

Another extremely useful thing is that it parses out SOCKS5 and ports if you copy paste a number of SOCKS5.
You can check unlimited SOCKS5 a day, but check Limit 50 SOCKS5 at a time.

What is the most efficient, quickest, lightest way to check if a SharePoint list exists in a SSO/MFA environment?

Option 1: Find a list by Title
It’s not ideal, but you can check if the list exists using this REST query:

https://YOUR_SITE/_api/Web/Lists/?$filter=Title eq 'Documents'

It does return some metadata, but with no list items.
You can reduce the amout of metadata you get by adding this header to your request:

accept: application/json; odata=minimalmetadata

Option 2. Send GET request using list URL

Send a GET request directly to the list URL

If you know a library/list URL, you can send a GET request to this URL. For example

https://YOUR_SITE/Library_THAT_DOES_NOT_EXIST

This will return a 404 status. It means that the list does not exist.

If you send a GET request to the library/list that exists, you will get 2** response, meaning it exists

https://YOUR_SITE/Shared Documents

sql server – Check if contract conflict with another contract query

I have a database with these tables as the bellow picture showed:

enter image description here

The user can create a new contract each contract may have one or more shops and these shops status changes depending on the contracts, everything works perfectly until now.
my problem in renewing the contract, I have a feature that allows the user to renew a contract, in this case, I get all the original contract info and make the new contract start from the end date of the original contract + 1 day with the same original contract info.

my question here is how to check if this renewal contract does not conflict with other contracts for the same customer and the same shops (customer can have many contracts)

E.G.:

I have contracts like this:

con_id    shop_id   start_date    end_date
--------------------------------------------
  1         1       14-04-2021    14-04-2022
  2         1       15-04-2022    15-04-2023

If the user clicked on contract number 1 and tried to renew it, I want a query to check if the new contract start date does not conflict with another contract for this user and these shops.

Like in my above data I want to prevent the user from renewing contract number 1 again because there is already a contract renewed before in that period.

This is what I tried:

--IF EXISTS (SELECT * FROM contracts_view where cust_id=123456789 and @date_start >= date_start and @date_start <= date_end and shop_id in (select shop_id from contracts_shops where contract_id =@old_contract_id)) 
--BEGIN
--    SELECT @ErrorMessage = ERROR_MESSAGE()
--  RAISERROR ('asdasd', 10, 1)
--  ROLLBACK TRAN
--   return
--END

and here is my stored procedure for renewing a contract:

ALTER PROCEDURE (dbo).(contract_renew)
-- Add the parameters for the stored procedure here
@cust_id int,
@duration int,
@price decimal(10,2),
@tax decimal(10,2),
@usage nvarchar(20),
@rent_type nvarchar(10),
@price2 decimal(10,2),
@note2 nvarchar(max),
@date_start date,
@date_end date,
@note nvarchar(max),
@app_user nvarchar(20),
@old_contract_id int
AS
BEGIN

DECLARE @ErrorMessage NVARCHAR(MAX)
DECLARE @ID int

BEGIN TRAN
BEGIN TRY

-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;

--insert data
INSERT INTO (dbo).(contracts)
       ((cust_id)
       ,(duration)
       ,(price)
       ,(tax)
       ,(usage)
       ,(rent_type)
       ,(price2)
       ,(note2)
       ,(date_start)
       ,(date_end)
       ,(note)
       ,(app_user))
 VALUES
       (@cust_id,
       @duration,
       @price,
       @tax,
       @usage,
       @rent_type,
       @price2,
       @note2,
       @date_start,
       @date_end,
       @note,
       @app_user) SELECT SCOPE_IDENTITY();

       SET @ID = SCOPE_IDENTITY();


insert into contracts_shops (contract_id, shop_id)
select @ID, shop_id
FROM contracts_shops WHERE contract_id = @old_contract_id;

COMMIT

END TRY
BEGIN CATCH
    SELECT @ErrorMessage = ERROR_MESSAGE()
    RAISERROR (@ErrorMessage, 10, 1)
    ROLLBACK TRAN
END CATCH
END

malware – Check USB mouse for malicious code

When I first used this mouse and keyboard, my PC died shortly after. Today I used it and it somehow corrupted my Linux.

I once put a clean Linux on a laptop and plugged this mouse in and left it, several times the laptop came out of sleep without being touched.

I have suspicions that it’s effectively a “rubberducky” and delivering a payload.

Is there a way to determine the risk? Can I install hard or soft USB monitoring?

Here’s a link to the mouse.

Is it possible to automatically check a polynomial to determine whether it has integer coefficients?

Given a polynomial f, I want to determine whether f has integer coefficients. More specifically, define

M[f_]:=MonomialList[f].

Is it possible to determine whether the coefficient of M[f][[k]] is an integer for k between 1 and Length[M[f]]?
