Learning about Deno building Gusano 🐍

Wilson Tovar — Mon, 18 May 2020 14:49:25 +0000

A few days ago I started to follow Deno more closely. Although I have more than 3 years of experience in Node JS the proposals that Deno makes seem very interesting to me.

So, a couple of days ago I decided to try it out 🤷. So I made a little library called "Gusano" (Worm) that allows you to create simple pipelines.

Gusano 🐍

A minimal workflows lib for Deno 🦖

Simple example

import { Block, Engine } from 'https://raw.githubusercontent.com/krthr/gusano/master/index.ts'

const sum : Block {

    id: 'sum',
    name: 'Sum block',

    run: (a, b) => Number(a) + Number(b),

    version: '0.1.0'

}

const engine = new Engine({ sum })

engine.on('end', ({ result, time }) => {
    console.log(result) // [3]
    console.log(time)   // 2
})

engine.start('sum', 1, 2)

A more complex example / Prime generator

/**
 * This block generates `n + 1`.
 */
export const generator: Block = {
  id: "generator",
  name: "Generator Block",
  version: "0.1.0",
  run: (n,

I want to share my entire learning journey with you in the future.

PS: I also receive suggestions and PR's ;) hahaa

Memmo: Don't leave home without having it installed!

Wilson Tovar — Sat, 04 Apr 2020 18:52:53 +0000

Hello, everybody! We're Juan (@sjdonado), Roberto and Wilson. We are Systems and Computational Engineering students from Colombia.

We are very excited to participate and create something that will help others.

So, this is our first publication about #twiliohackathon. Every week we'll be posting 2 or 1 updates of the project.

What We built

We are building a mobile application called Memmo to generate alerts in case any user has been too close to a person who now has covid-19.

We will collect the geolocation of each user (4am - 10pm). When new cases of COVID-19 are reported we will search for each new patient on our platform. If we find one, we will notify other users who have been within 2 meters of the patient in the last 14 days.

How does it work?

Soon

Haye.cr: Expressive string syntax to Array/Hash and Vice-Versa parser for Crystal. Based on the javascript version.

Wilson Tovar — Thu, 12 Dec 2019 15:29:12 +0000

I have published the Crystal version of Haye: An expressive string syntax to Array/Hash and Vice-Versa parser for Crystal. Based on the javascript version.

GitHub repo: https://github.com/krthr/haye.cr

Here is an example:

Usage

require "haye.cr"

Pipe -> Array

expression = 's'
parsed = Haye.fromPipe(expression) # Haye.fromPipe(expression, Haye::PresenterTypes::Array)

Output (Haye::Presenters::Node[])

[
  #<Haye::Presenters::Node:0x7f11fd891e40 
    @name="required", 
    @args=[]
  >, 
  #<Haye::Presenters::Node:0x7f11fd891de0 
    @name="email", 
    @args=["unique", "users"]
  >
]

Pipe -> Hash

expression = 's'
parsed = Haye.fromPipe(expression, Haye::PresenterTypes::Hash)

Output (Hash)

{
  "required" => [], 
  "email" => ["unique", "users"]
}

I hope you enjoy!

Pope.cr: Micro templating engine for strings only. (Crystal version of Pope.js)

Wilson Tovar — Wed, 11 Dec 2019 04:06:21 +0000

I have published the Crystal version of Pope: A fast, minimal and micro template engine for strings only, it plays well where you want to embed micro templates inside your module.

GitHub repo: https://github.com/krthr/pope.cr

Here is an example:

require "pope.cr"

data = {
  user: {
    id:       123,
    username: "krthr",
    admin:    true,
    config:   {
      email: "test@test.com",
    },
  },
}

Pope.pope(
  "The user {{user.username}} with id {{user.id}} is cool",
  data
) # "The user krthr with id 123 is cool"

Pope.prop(data, "user.id")           #  123
Pope.prop(data, "user.config.email") # test@test.com
Pope.prop(data, "nananana")          # nil

I hope you enjoy!

Best option to start a new big project - NodeJS

Wilson Tovar — Sun, 01 Oct 2017 03:55:03 +0000

Hey! I will begin a moderately big project together with a friend, but still we do not define the technology that we will use. We begin with "Sails", but... yet it is very young and the bugs abound. We have searched a lot about new technologies. What do you recommend to us? Thank you!

Bubble Sort in Ruby

Wilson Tovar — Fri, 28 Jul 2017 18:00:36 +0000

Original publication: Seis Algoritmos en Ruby - @Kinduff

It is the most basic way of arranging a collection. It iterate on every value and it compares with the following one, they are exchanged of being necessary, the iteration repeats itself until all the values are not exchangeable.

def sort(values)
  length = values.size - 2
  swapped = true

  while swapped
    swapped = false

    0.upto(length) do |i|
      if values[i] > values[i+1]
        values[i], values[i+1] = values[i+1], values[i]
        swapped = true
      end
    end
  end

  return values
end

sort([7, 4, 5, 2, 9, 1])

# =>
# 7, 4, 5, 2, 9, 1
# 4, 5, 2, 7, 1, 9
# 4, 2, 5, 1, 7, 9
# 2, 4, 1, 5, 7, 9
# 2, 1, 4, 5, 7, 9
# 1, 2, 4, 5, 7, 9
