5 Takeaways from a University of Toronto Machine Learning Student

It is no secret that the University of Toronto is one of Canada’s most highly ranked universities, but not all its campuses are seen as equals. The Scarborough campus, that I will refer to as UTSC, is a newer campus located at the East end of the GTA and offers a wide variety of Co-Op programs a freshman can select from.

About 4 years ago, when I was applying to universities, I decided to attend the University of Toronto Scarborough Campus as a Co-Op Computer and Mathematical Science student, with the goal of entering the Computer Science (CS) program (that you must apply for after your first year of undergraduate studies).
Here are five things that I learned throughout my journey and how I started my Data Science career:

How to Use Strapi with Angular Universal Apps

Angular is a powerful feature-rich platform that you can use to create all kinds of single-page apps, ranging from simple sites to more intricate ones. With it, you can build efficient native, web, and mobile apps with a wide range of tools and libraries it integrates. However, there are still ways apps built with it can be improved. For example, using Angular Universal, you can render your apps server-side to speed up page loads and improve SEO and performance.

Server-side rendering involves converting an app to HTML on a server. When you send a request for a particular path to the server, it returns an entirely static HTML page as a response. No additional requests need to be made to populate the page with data and resources as it is all contained in the response. The page appears almost precisely how it would be rendered client-side in the DOM but may sometimes have limited functionality.

Angular Universal is a set of tools that render Angular apps server-side. On the server, the Universal template engine takes an Angular app and creates static pages when a request is made. The pages are then forwarded to the client. It’s likely called universal since it executes on other platforms besides a browser.

Server-side rendered apps load quicker to users. A static page is shown to the user to engage them as the rest of the application loads. The static pages that Angular Universal provides are simple to index when search engine web crawlers access them. This server-side rendering improves the SEO score of a site. In addition, SSR pages offer a better user experience, especially on less capable devices that may have trouble running full Angular apps.

Strapi is an open-source content API. Data from it can be consumed using REST or GraphQL. With it, you can set up APIs relatively fast. It also provides an admin panel where you can manage the API and content. You can use it with several different databases such as SQLite, MySQL, PostgresSQL, MongoDB, etc. Additionally, it is highly customizable and offers numerous plugins to supplement the API.

This article will cover how to use Strapi with an Angular Universal app. First, you’ll set up a Strapi server. Then you will create an Angular Universal app that will consume data from Strapi.

Prerequisites

Before you begin, you need to have Node installed. You can find out how to get it  here. The version of Node needs to be at minimum 12 and at most 14. You also have to have the Angular CLI installed.  This guide will walk you through how to do this.

A Simple Middleware-style Router For Isomorphic JavaScript Web Apps

Universal Router

A simple middleware-style router that can be used in both client-side and server-side applications.

Visit Quickstart Guide (slides)  |  Join #universal-router on Gitter to stay up to date

Features

• It has simple code with only single path-to-regexp dependency.
• It can be used with any JavaScript framework such as React, Vue, Hyperapp etc.
• It uses the same middleware approach used in Express and Koa, making it easy to learn.
• It supports both imperative and declarative routing style.
• Routes are plain JavaScript objects with which you can interact as you like.

What users say about Universal Router

Just switched a project over to universal-router. Love that the whole thing is a few hundred lines of flexible, easy-to-read code.

-- Tweet by Greg Hurrell from Facebook

It does a great job at trying to be universal — it's not tied to any framework, it can be run on both server and client, and it's not even tied to history. It's a great library which does one thing: routing.

-- Comment on Reddit by @everdimension

Installation

Using npm:

npm install universal-router --save

Or using a CDN like unpkg.com or jsDelivr with the following script tag:

<script src="https://unpkg.com/universal-router/universal-router.min.js"></script>

You can find the library in window.UniversalRouter.

How does it look like?

import UniversalRouter from 'universal-router'

const routes = [
  {
    path: '', // optional
    action: () => `<h1>Home</h1>`
  },
  {
    path: '/posts',
    action: () => console.log('checking child routes for /posts'),
    children: [
      {
        path: '', // optional, matches both "/posts" and "/posts/"
        action: () => `<h1>Posts</h1>`
      },
      {
        path: '/:id',
        action: (context) => `<h1>Post #${context.params.id}</h1>`
      }
    ]
  }
]

const router = new UniversalRouter(routes)

router.resolve('/posts').then(html => {
  document.body.innerHTML = html // renders: <h1>Posts</h1>
})

Play with an example on JSFiddle, CodePen, JS Bin in your browser or try RunKit node.js playground.

Internal Working of HashMap in Java

Know your next interview question.

I have seen a lot of interviewers asking for the internal working mechanism of the hashmap. If you know the complete internal working of one of the map implementations, it becomes easier for you to understand the other classes of the map interface.So thru this article, we’ll see how the hashing is done and its complete working mechanism, how the search, insert and removeoperations work with the hashmap and their time complexities, and at the end, we’ll see why it should not be used in a multi-threading environment.
