Ubuntu 19.10 Login

I love beautiful minimalist designs. Today we are gonna create together Ubuntu 19.10 (Eoan Ermine) Login. Using Semantic HTML and CSS only.

Why Semantic HTML and CSS only? Why aren’t we going to use JavaScript?

Well, you should use JS only when needed and as you will see, we can go quite far without it. You can recreate cool effects with CSS only.

Rely on CSS as much as you can (also some parts can be GPU accelerated).

1 Define your parts

First of all, check again at the very top of the article the Pen or the image with the Ubuntu Login. We need to think about the diferent parts of our login to break it into pieces. …

Ubuntu Terminal Adwaita-dark

The minimalist design for Ubuntu combine with the famous Adwaita theme are beautiful and unique. If you are starting with Web technologies or want to refresh some fun CSS concepts you can join me recreating this Ubuntu terminal in CSS.

Semantic HTML

We are going to organize the differents parts (components) of The Ubuntu terminal but instead of using divites (divs tags every where), overdose of attributes, classes…

<div class="col-xs-12 col-sm-6 col-md-8"><button class="toolbar__button toolbar__button--exit">&#10005;</button><div class="terminal-prompt-title"></div></div>

We are going to use our own Semantic HTML. You already know the difference:

Examples of non-semantic elements: <div> and <span> - Tells nothing about its content. …

A nice list of General Web, HTML, CSS and JavaScript questions that we used during interviews in my previous job : )

General

What is HTTP?

HTTP stands for HyperText Transfer Protocol, a protocol for transmitting resources across the internet.

AJAX stands for Asynchronous JavaScript and XML, a set of tecnniques for asynchronous calls that fetch data from a server and update the web without reloading.

Game of Frameworks by gengns on DeviantArt

Powerful enhancements that are coming to the standard and ideas that would make our lives even easier when dealing with web technologies.

[DOM] Print any element

Print any element of the document with its own style.

document.querySelector('div').print()

The standard only supports window.print() but it would be really interesting if it was possible to print anything we want to as it’s shown.

[JS] Flatten nested elements

There is already a proposal for arrays in the specification.

// current proposal solution
[1, 2, 3, [4, 5]].flat() // [1, 2, 3, 4, 5]

It would be really useful to extend the same approach for objects.

const obj = { 
name: 'mario',
work: {type: 'cto', salary: 80000, country: 'es'}…


I want to dedicated this article to one of the best and humble programmers I’ve ever known, who guided me through the inscrutable paths of JavaScripts.

I think I’m starting to be a little too tiresome with JavaScript.

Operating Systems in my house by Randall Munroe

I realised this when I started meeting people and introduce myself following as “what’s the world most popular language? French, English, Spanish or JavaScript”, “have you ever listened about the great history behind JavaScript…” (playing in the background Conan the Barbarian OST) after what many of the them answered me with the typically “I know Java, it’s a programming language” ¬¬

What’s the difference between Java and Javascript?

A nice list of HTML, CSS and JavaScript How Tos with basic concepts for everyday use. Feel free to comment your own approaches :)

Disabling everything with CSS

Split an array into chunks without mutability

JS

const array = [1, 2, 3, 4]
const size = 3
const new_array = array.reduce((acc, a, i) => {
i % size ? acc[parseInt(i / size)].push(a) : acc.push([a])
return acc
}, [])

or even shorter

const new_array = array.reduce((acc, a, i) =>
i % size ? acc : […acc, array.slice(i, i + size)], [])

Remember, start using const, if you need to change its value then use let and avoid as much as possible var. …

No todas las ideologías y costumbres son respetables, sobre todo cuando te pueden hacer daño: la ablación del clítoris, el apaleamiento de homosexuales, tirar cabras de campanarios, escupir a madres solteras, etc.

La religión los programa en la ignorancia, les inculcan el rezo periódico y a la negación absoluta contra cualquier pensamiento que pueda peligrar su fe. …


Hay una serie de preguntas religiosas de las que quizás, al igual que yo, estés bastante cansado de oírlas. A continuación, un batallón de respuestas para lidiar con ellas.

Creyente: ¿Por qué no crees en Dios?

Agnóstico: Soy ateísta agnóstico, una postura que no está basada en creencias, básicamente, si tu como creyente me vienes diciendo que Dios existe, yo te pediré que me lo demuestres, si no me lo demuestras no podré creerte. Si lo piensas, en realidad todos somos algo agnósticos. (Ricky Gervais)

C: Si tan claro tienes que Dios no existe, demuéstrame que no.

A: Esto es una Falacia, el hecho de que no se pueda demostrar su no existencia no implica que exista. Ejemplo: demuéstrame que no existe un unicornio rosa. …
