The Self-Taught Programmer

software engineer II at eBay. Once I got there, I realized I was severely under-prepared. I was overwhelmed by the amount of things I needed to know but hadn’t learned yet. My journey learning to program, and my experience at my first job as a software engineer were the inspiration for this course.

This course is not just about learning to program; although you will learn to code. If you want to program professionally, it is not enough to learn to code; that is why, in addition to helping you learn to program, I also cover the rest of the things you need to know to program professionally that classes and books don’t teach you. The Self-taught Programmer is a roadmap, a guide to take you from writing your first Python program, to passing your first technical interview. I divided the course into five sections:

1. Learn to program in Python 3 and build your first program.

2. Learn Object-oriented programming and create a powerful Python program to get you hooked.

3. Learn to use tools like Git, Bash, regular expressions and databases. Then use your new coding skills to build a web scraper.

4. Study Computer Science fundamentals like data structures and algorithms.

5. Finish with tips for working with a team and landing a programming job.

How to Draw 101: BASIC DRAWING SKILLS & Sketching Exercises

This is the first episode of my How to Draw Series. This course is about Basic Drawing Skills and 3D Sketching.

If you are an absolute beginner at drawing, this session can be a perfect choice for your very first drawing course. Or if you are not a beginner, but you are having difficulties with your drawings, you are just probably missing some of the basic puzzles which can be easily fixed in these lessons.

This course requires no previous drawing knowledge or special drawing equipment.
We’ll be drawing with simple traditional graphite pencil on ordinary paper.

The first section is kind of an introduction to drawing.
I will show you

  • the drawing tools you need
  • optional tools for the future
  • how to hold the pencil to get a better drawing experience
  • how to see the world with the eyes of the artist

In the second section we will go through the basic building blocks of drawing. We will develop your basic drawing skills making a lot of fundamental drawing exercises.

You will learn how to draw

  • straight lines
  • parallel lines
  • simple 2D shapes like triangles, rectangles, and squares
  • curves
  • circles, ovoid shapes, and ellipses
  • simple 3D objects like cubes and cylinders

We will also develop your hand coordination by connecting dots with straight and curved lines.

The goal of these lessons is to gain confidence at drawing these simple elements that we will use to build more complex objects.

I will give you an introduction to perspective drawing discussing the most frequently used 2-point and 3-point perspective. I will also explain an important drawing principle called foreshortening. With this knowledge you’ll be able to draw subjects convincingly in the 3D space.

In the third section we’ll put the drawing skills you’ve learned into practice. We will make all sorts of sketches on real life subjects based on reference photos. We will draw

  • a chess pawn built from simple 2D shapes
  • a chair by drawing straight lines using the rules of perspective
  • a fish using a bunch of S-curves
  • a profile portrait to practice proportions
  • a chess pawn with simple shading
  • a pair of glasses
  • a dancing human figure for an introduction to gesture drawing
  • and an astronaut just for fun

At the end of the course you can check if your drawing skills have improved. You can compare your sketches made at the beginning and at the end of the course. If you make all the exercises with me, I’m sure you will make a difference.

Develop Java MVC web apps using MyBatis, Servlets and JSP

Servlets and JSP

A Java servlet is a Java software component that extends the capabilities of a server. Although servlets can respond to many types of requests, they most commonly implement web containers for hosting web applications on web servers and thus qualify as a server-side servlet web API. Such web servlets are the Java counterpart to other dynamic web content technologies such as PHP and ASP.NET.

A Java servlet processes or stores a Java class in Java EE that conforms to the Java Servlet API, a standard for implementing Java classes that respond to requests. Servlets could in principle communicate over any client–server protocol, but they are most often used with HTTP. Thus “servlet” is often used as shorthand for “HTTP servlet”. Thus, a software developer may use a servlet to add dynamic content to a web server using the Java platform. The generated content is commonly HTML, but may be other data such as XML and more commonly, JSON. Servlets can maintain state in session variables across many server transactions by using HTTP cookies, or URL mapping.

To deploy and run a servlet, a web container must be used. A web container (also known as a servlet container) is essentially the component of a web server that interacts with the servlets. The web container is responsible for managing the lifecycle of servlets, mapping a URL to a particular servlet and ensuring that the URL requester has the correct access rights.

The Servlet API, contained in the Java package hierarchy javax.servlet, defines the expected interactions of the web container and a servlet.

Servlets can be generated automatically from JavaServer Pages (JSP) by the JavaServer Pages compiler. The difference between servlets and JSP is that servlets typically embed HTML inside Java code, while JSPs embed Java code in HTML. While the direct usage of servlets to generate HTML has become rare, the higher level MVC web framework in Java EE (JSF) still explicitly uses the servlet technology for the low level request/response handling via the FacesServlet. A somewhat older usage is to use servlets in conjunction with JSPs in a pattern called “Model 2”, which is a flavor of the model–view–controller.

MyBatis is a Java persistence framework that couples objects with stored procedures or SQL statements using an XML descriptor or annotations.

Apache MyBatis

MyBatis is free software that is distributed under the Apache License 2.0.

MyBatis is a fork of iBATIS 3.0 and is maintained by a team that includes the original creators of iBATIS.

Unlike ORM frameworks, MyBatis does not map Java objects to database tables but Java methods to SQL statements.

MyBatis lets you use all your database functionality like stored procedures, views, queries of any complexity and vendor proprietary features. It is often a good choice for legacy or de-normalized databases or to obtain full control of SQL execution.

It simplifies coding compared to JDBC. SQL statements are executed with a single line.

MyBatis provides a mapping engine that maps SQL results to object trees in a declarative way.
