Past fifty years the golden earring in her ear has the same glint


The sprint is now a bent walk

The heart beats slower and the kidney back outs

Fantastically, the smile retains the beautiful bent

The twinkling crescent in the eye makes the populace relent

I remember her as the energetic soul

For whom service to everyone was a divine parol

The radiant smile and the gaily gait

She wooed everyone with her selfless trait

She has always had a strong-willed mind

A person so delightful as my grandma is hard to find

This article aims to cover what is quorum consistency, why do we need it and it’s limitations in case of multiple replica system.

Preventing our data from believing this

“The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong it usually turns out to be impossible to get at or repair.”
Douglas Adams, Mostly Harmless (1992)

Quorum consistency is used in systems where consistency is more important than availability (CAP theorem) for write and read but we still want a fairly available system.

In systems with multiple replicas there is a possibility that the user reads inconsistent data. This happens say when there are 2 replicas, N1 and N2 in a cluster and a user writes value v1 to node N1 and then another user reads from node N2 which is still behind N1 and thus will not have the value v1, so the second user will not get the consistent state of data. …

The walls come closer and crushed I am

I’ve lost my voice but a shrieking noise I hear

Dismal images dawn my mind

My life is obsolete

My boons are my banes

Fantastically, my hope still reigns

I reach for a friend in that inferno and I feel a hand

An explicable sensation hits my heart

With a smile I look down

Both my hands are holding each tight

I’ve found my eternal friend

My partner for life

I’m DOM, Shadow DOM

This is a basic introduction to what is a Shadow DOM and how ,when and why to use a Shadow DOM.

What is Shadow DOM?

In simple words, it’s a DOM inside a DOM.

Using Shadow Dom, you can attach a separate DOM tree which is hidden and encapsulated to any element. This is very helpful to achieve encapsulation in web components.
