## Can I split a gravity forms postcode field by the space so just the first half of the postcode is entered automatically into a text field

reaching out on this one. I’m using gravityforms address field and need a simple text field to display just the first half of the postcode.

Example

Postcode Field: E14 4RD Text Field: E14

No idea where to start I’ve Googled and asked on gravityforms forum but no luck.

Any pointers would be great

## Plsql query to split data based on startdate and end date

I want to split data based on start ,end date ,date range configured (yearly/monthly/weekly/quarterly)

For example if the

Startdate is 2015/10/02 and the

Enddate is 2015/12/22

and my date range is Monthly (M)

then my required output is:

Output ------------- Newstartdate newEnddate 2015/10/02.   2015/10/31 2015/11/01.   2015/11/30 2015/12/01.   2015/12/30 

So I was looking for a generic PL/SQL query to split data what ever date range can be(Y/Q/M/W/D) based on the start and end dates and the range specification.

## Split data across multiple rows in a single statement

I have data in table like

Customer Invoice No Date Value Paid Balance
ABC 1 01/12/2020 25 0 25
ABC 2 01/12/2020 50 0 50
XYZ 3 02/12/2020 200 0 200
XYZ 4 04/12/2020 100 0 100
ABC 5 04/12/2020 500 0 500

Now I received amounts for customers as below

ABC 540 XYZ 210

ABC XYZ
540 210

After receiving the amounts my table should like this

Customer Invoice No Date Value Paid Balance
ABC 1 01/12/2020 25 25 0
ABC 2 01/12/2020 50 50 0
XYZ 3 02/12/2020 200 200 0
XYZ 4 04/12/2020 100 10 90
ABC 5 04/12/2020 500 465 35

I got some clues but this works only for date based values but I need customer and date based.

Any help will be appreciated

## Use Mathematica to split a sequence according to other two sequences

I want to use Mathematica to solve the following problem:

For example I have a sequence 101. I want to compare it with $$1101$$ and $$0101$$. The comparison has the following procedure:

1. Check the first term of $$101$$ is $$1$$ or $$0$$. If it is $$1$$, compare $$101$$ to $$1101$$, term by term; If it is $$0$$, compare $$101$$ to $$0101$$. Stop the process before the first term they are different, or all the terms of $$101$$ have been compared without stopping the process, and report all the terms that have been compared.

In our case, the first term of $$101$$ is $$1$$, so we compare it with $$1101$$. Then, $$101$$ and $$1101$$ only has one term in common, the first term $$1$$. So the program should report $$1$$, and go to next step.

1. Recording the remaining sequence of $$101$$.

In our case, as only $$1$$ is reported, the remaining sequence is $$01$$.

1. Restart the process. Check the first term of $$01$$ is $$0$$ or $$1$$. If it $$0$$, compare $$01$$ with $$0101$$, if it is $$1$$, compare $$01$$ with $$1101$$. Stop the process before the first term they are different, or the sequence of $$01$$ has been run out. Report all the timers that have been compared.

*In our case, the first term of $$01$$ is $$0$$, so we compare $$01$$ with $$0101$$. Then the first two terms agree, and then $$01$$ ran out. The program should report $$01$$, and then stop.

1. Repeating the process again and again until there is no remaining sequence.

I tried to use the commend "If" to write this but it did not work, since I did not know how to let Mathematica to "remember" what has been compared.

Then, I tried to use commend "Order" and "Sort", but it seems that I need to program a comparison function.

Is there anyway for me to achieve this using Mathematica? Thank you!

## how to split and upload a theme on wordpress?

I have created an account on googiehost and unfortunately the hosting company has limited the file upload size to 2MB. Since the hosting is free on googiehost the hosting provider may not agree to increase the file upload size for just my account. And now i have this Divi theme which is 8 MB in size and i am unable to upload it due to the limit. So i thought off splitting the Divi.zip file into 4 X 2MB chunks which later makes up 8MB(The theme) and then give to any plugin so that it takes all the chunks and extract them to the path where the theme is actually supposed to be installed. So my question is there any plugin as such which does what i want.

## Does a Split Party Gain XP Evenly?

I’m running a campaign with six player characters. Since it’s a larger group, they occasionally split up. During these times, individual groups have gotten into encounters and been awarded XP.

My question is, does this XP get split evenly among the group present at the encounter or does the entire party, including the non-present group, receive XP evenly across the board?

## Independent sets into which all the vertices of the graph can be split

How to prove that if $$G$$ is an acyclic transitive digraph, then the least independent sets into which all vertices of G can be divided is equal to the size of the longest paths to $$G$$?

## Problem using ‘Regular expression’ in order to split characters of a column when there is no delimiter between them

I have a table with below structure:

create table TBL_TEST (   col_id   NUMBER,   col_name VARCHAR2(500) ) 

Some example data :

col_id | col_name    -----------------   1    | aetnap           2    | elppa          3    | ananab        

What I need to do is to split characters of column col_name for each col_id for example for col_id=1 we must have :

col_id | col_name    -----------------   1    | a   1    | e   1    | t   1    | n   1    | a   1    | p 

this query is fine when there is only one record in the table :

SELECT col_id, REGEXP_SUBSTR(col_name, '[a-z]{1}', 1, LEVEL) AS VAL   FROM tbl_test t CONNECT BY REGEXP_SUBSTR(col_name, '[a-z]{1}', 1, LEVEL) is not null 

but as soon as I insert another record in the table (say col_id=2 and col_id=3) I can not have the desired result. I want to know two things:

1. Why is this query works fine for one record and it does not for more ?
2. what is the best way to split the characters when there is no delimiter between them?

## Multi-level paging where the inner level page tables are split into pages with entries occupying half the page size

A processor uses $$36$$ bit physical address and $$32$$ bit virtual addresses, with a page frame size of $$4$$ Kbytes. Each page table entry is of size $$4$$ bytes. A three level page table is used for virtual to physical address translation, where the virtual address is used as follows:

• Bits $$30-31$$ are used to index into the first level page table.
• Bits $$21-29$$ are used to index into the 2nd level page table.
• Bits $$12-20$$ are used to index into the 3rd level page table.
• Bits $$0-11$$ are used as offset within the page.

The number of bits required for addressing the next level page table(or page frame) in the page table entry of the first, second and third level page tables are respectively

(a) $$\text{20,20,20}$$

(b) $$\text{24,24,24}$$

(c) $$\text{24,24,20}$$

(d) $$\text{25,25,24}$$

I got the answer as (b) as in each page table we are after all required to point to a frame number in the main memory for the base address.

But in this site here it says that the answer is (d) and the logic which they use of working in chunks of $$2^{11} B$$ I feel ruins or does not go in with the entire concept of paging. Why the system shall suddenly start storing data in main memory in chucks other than the granularity defined by the page size of frame size. I do not get it.

## Split a JWT between payload and signature

Context: I’m looking at storage solutions for JWT tokens on a single page application.

1. Storing the JWT in the local storage is unsafe and prone to XSS attacks.
2. Storing the JWT in a secure / HTTP only cookie is safer, but prone to CSRF attacks.

I’m studying the following scenario:

Upon authentication, a refresh token is stored in an http only secure cookie. It can only be used to get an access token.

Upon authorisation, the backend responds with a JWT access token. The header and payload part of the JWT are inside the response body. The token signature is not sent and is set in an http only secure cookie (same-site strict if possible, but let’s assume it’s not the case). The header + payload is stored in memory.

When making requests, the header + payload is sent via XHR/fetch by the SPA in an Authorisation header. The signature is sent along with the cookies. The backend concatenates both and verify the signature.

Would such a mechanism be safe from XSS and CRSF attacks, or is it just adding un-necessary complexity ? Since the cookie does not contain the full JWT, this seems like a CSRF attack would not be able to make requests. And an XSS attack would at least (this is a mild protection at this point since an XSS attack is possible, but still), not be able to retrieve the full token.

Note: I’ve read this question which is similar, but overly broad so I’m posting this to get a more precise answer.
