I have a txt document of 200k+ lines. I want to add different characters to all carriage returns and different characters to all line breaks. How can I do it?
Use EMEditor for handling files with big data.
You can select all lines, split them for single lines.
You'll have multiple cursors and whatever you'll write will be written for all the cursors.
Press end or home to move to the line start or end.

I want to convert a string ordinal to a number in perl
I have searched but not get exact answer.
Example: if the input is
one it should be 1.
five hundred it should be 500.
three hundred it should be 300.
Is there any module to do this?
One of the best parts of Perl is CPAN and, sure enough, a couple minutes of poking around on metacpan turned up the Lingua::EN::Words2Nums module:
use Lingua::EN::Words2Nums;
$num=words2nums("two thousand and one");
$num=words2nums("twenty-second");
$num=words2nums("15 billion, 6 million, and ninteen");

I noticed that Slack uses ID's of the form U023BECGF, and not the standard f3a7a018-02da-4cdb-944c-44d073536648 you often see
What is the reasoning for this?
The code you put in your question (U023BECGF) is not a valid or complete UUID. UUIDs are 16 bytes (octets) which are represented as 32 characters of hexadcimal as standard: RFC: https://www.ietf.org/rfc/rfc4122.txt
Under no encoding is U023BECGF a representation of a 16 bytes; it's too short.
It is plausable that these keys could be incorperated into a UUID but they are not one in themselvs.
The usual reason for smaller fields is storing less data.

What speed optimization techniques do antiviruses use today to scan a file, provided they have to check for all the signatures + the behavioral scan?
I'm not a antivirus programmer, but I think the scan engine scans through a file searching for known pattern inside. The greater number of patterns it can identify, the longer it will take to scan.
Optimization maybe similar to database optimization, with patterns indexing.

I want to select certain amount of data from one table. Based on those data, I want to check another two tables and insert into 2 tables.
So I want to iterate the resulted data. Which way is better(faster) and reasonable using DataReader or DataTable?
Thanks in advance

You end up creating a reader to fill the table. The reverse isn't true, So I would stick with the dataReader.
