Today I discovered Miller—it's like jq but for CSV: "Miller complements data-analysis tools such as R, pandas, etc.: you can use Miller to clean and prepare your data." @GreatBlueC @nfmcclure— Adrien Trouillaud (@adrienjt) September 24, 2020.

Miller is like sed, awk, cut, join, and sort for name-indexed data such as CSV: - handy tool!— Ilya Grigorik (@igrigorik) August 22, 2015. Btw, I think Miller is the best CLI tool to deal with CSV.

Miller: a *format-aware* data munging tool By @__jo_ker__ to overcome limitations with *line-aware* workshorses like awk, sed et al project website is a fantastic example of good software documentation!!— Donny Daniel (@dnnydnl) September 9, 2018. Holy holly data swiss army knife batman! How did no one suggest Miller for solving database cleaning / ETL issues to me before Congrats to @__jo_ker__ for amazingly intuitive tool for critical data management tasks!#DataScienceandLaw #ComputationalLaw— James Miller (@japanlawprof) June 12, 2018. @__jo_ker__'s Miller easily reads, transforms, + writes all sorts of tabular data. It's standalone, fast, and built for streaming data (operating on one line at a time, so you can work on files larger than memory).And the docs are dream. I've been reading them all morning!

Rabin-Miller test to Carmichael numbers

Asked 2022-Mar-17 at 13:40

I am a computer science student, I am studying the Algorithms course independently.

During the course I saw this question:

Show an efficient randomized algorithm to factor Carmichael numbers (that is, we want a polynomial time algorithm, that given any Carmichael number C, with probability at least 3/4 finds a nontrivial factor of C). Hint: use the Rabin-Miller test.

my solution:

my idea is use Rabin-Miller test: i will check if C is prime i will use Rabin-Miller Primality tests steps:

Find n-1=c^k*m

choose a: 1 < a < n-1

compute b_0 = a^m(mod n), b_i = b_(i-1)^2 (mod n)

if b_0 = -/+1 this is prime, i will return nothing. if b_i = -1 this is prime, will return nothing. else if = 1 this is not prime i will return the factor of C.

algorithm:

If Miller–Rabin fails on a Carmichael number n, then as a byproduct you get some x ≢ ±1 mod n such that x² ≡ 1 mod n. Both gcd(x + 1, n) and gcd(x − 1, n) are proper divisors of n.

The proof: x ≢ 1 mod n is equivalent to x − 1 ≢ 0 mod n, which is equivalent to x − 1 not being divisible by n. Therefore gcd(x − 1, n) ≠ n. Likewise, x ≢ −1 mod n implies that gcd(x + 1, n) ≠ n.

On the other hand, x² ≡ 1 mod n is equivalent to (x + 1) (x − 1) being divisible by n, hence gcd((x + 1) (x − 1), n) = n. We cannot have gcd(x + 1, n) = 1, or else gcd(x − 1, n) = n (since gcd(a b, c) = gcd(a, c) for all b such that gcd(b, c) = 1). Likewise, gcd(x − 1, n) ≠ 1.

I created a simple example from the HTML and data you provided https://stackblitz.com/edit/angular-vuzjyk

The reason {{ item.value }} shows [object Object] is because you didn't give it an identifier to pick the property of that object you wish to display.

To simplify, I updated your rows[] to match the keys of your data to use it directly.

QUESTION

how to repeat the height for grid-auto-rows

Asked 2022-Feb-08 at 22:51

I am trying to show only the first two rows of a CSS GRID.
The width of the container is unknown therefore it should be responsive.
Also the content of each box is unknown.

My current hacky solution is to define the following two rules:

use an automatic height for the first two rows
set the height of the next 277 rows to 0 height

grid-auto-rows: auto auto 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0;

I tried repeat() like this: grid-auto-rows: auto auto repeat(277, 0px) but unfortunately it didn't set the height to 0.

Is there any clean way to repeat height 0?
