slider do zero ( html + css + js )

gostaria de uma luz em como criar um líder simples de fotos deslizantes no estilo do slick porém sem usar o slick slider e sim criar do zero, pois as formas que o estilo css do slick slider foram formatadas nao atendem ao que eu quero criar, preciso implementar esse slider de 3 ou mais imagens em uma página web , se não puderem responde por aqui ou ainda quiserem me explica melhor meu insta é @Eberth.Silva , obrigado desde já .

Zero Day Policies implementation

I’m new here, and sorry if my english is a little bit broken it’s not my main language.

I’m trying to put together a document/ppt for my startup with a Zero Day policy structure.

But I’m not finding real implemented flows, information, or something I can base this from (anything is helpfull)

What I found on my research mainly focus on specific discussing how heartbleed or the cve work.

I want to put something very straightforward but would love different point of views or examples if there are like:

  • We will be suscribed to receive every update automatically from the different applications, OS that we own
  • Critical updates will be reviewed, researched and implemented at top on 48 hours on all the servers
  • Medium/Urgent updates will be reviewed, researched and implemented at top on 1 week on all servers
  • Low Updates will be reviewed and implemented at most on the same month
  • A Team will monitor the audits logs of ports that are reporting status that are receiving suspected activity once a week on a internal meeting and define if new meassures have to be implemented
  • ETC

Problem class of assigning N persons to N tasks, zero costs with prefs

I am looking for the general problem class / computational complexity / algorithms for the following problem:

N tasks must be accomplished by N persons. 1 task to be done by exactly 1 person and vice versa. There is a binary preferences matrix whose (i,j) entry is 0 if person i can not do task j, and 1 if it can.

There are no costs involved, no weights and the number of tasks equals the number of people.

I was searching for it but all I could find was the Assignment Problem which has costs/weights associated with each assignment.

As a last resort, perhaps I can transform my preferences matrix to a cost matrix if person can not do job then cost is infinite else cost is zero?

Ubuntu MDADM Raid 1 Accidental Zero Superblock

I’ve spent the past 24 hours trying to resolve my issue. While attempted to add another 2 disc raid to my server I accidentally changed the label for one of my drives in the original raid. To further complicate my issue, I accidentally zeroed the superblock on the remaining good drive. I’ve been having a lot of medical issues lately and I should not have been trying to do this upgrade. But, I’m at a loss for recovering my data, 4TB worth, with many files not backed up elsewhere.

To recap:

I was trying to setup labels on a new pair of drives (sdc and sdd), when I accidentally changed the label of an existing raid drive (sdb).

While trying to setup sdc and sdd as raid 1 after a failed attempt, I accidentally ran sudo mdadm --zero-superblock /dev/sda on my first raid, which ruined my remaining backup of the data.

I’m not a super expert in Ubuntu, but have gotten by until today. If anyone can help me recover this data I would be eternally grateful. I’m at a total loss.

Structure of the variety of $n$-tuples of $m \times m$ matrices with zero product

Consider the functor sending a commutative ring $ R$ to $ \{(A_1,\dots,A_n) \in ( M_m(R) )^n | A_1 \dots A_n =0 \}$ which defines a scheme over $ \mathbb Z$ , let $ X$ be its base change to $ \mathbb C$ .

When $ m=1$ , it’s easy to see $ X$ is not irreducible but reduced. In general, is $ X$ reduced? Can we describe the irreducible components and smooth locus?

The main question is about the computation of cohomology groups. As $ X$ is a cone (so is contractible topologically), we know higher etale cohomology is trivial (by comparison theorem with singular cohomology).

What is the compactly supported cohomology group $ H^i_{et, c}(X, \mathbb Z_l)$ ?

Note $ X$ may not be (rationally) smooth, so Poincare duality may fail. The approach through counting over finite fields is also very complicated.

There is a natural conjugacy action of $ GL_m$ on $ X$ (and action of $ (\mathbb G_m)^n$ by scaling). If one wants to use this to compute the compactly supported cohomology, how to describe the orbits?

Edit: a motivation for such consideration is the nilpotent cone, which is rationally smooth and the number of points over a finite field has a very simple expression.
