CCATP #698 – Bart Busschots on PBS 124 of X – Chezmoi Templates (9/4/2021) by podfeet

Bart has been really excited to teach this next installment of Programming By Stealth where we really dig into learning about Chezmoi templates, including learning functions and arguments, how to declare variables, looping over arrays, and learning the sprig utility functions to extend Chezmoi. I thought he was going to jump out of his chair he was so happy to teach pipelines which are a grand way of embedding function statements in a way that is very human-readable.

This is our penultimate installment on Chezmoi, where next time we’ll be learning how to manage our dot files across multiple computers where not everything is the same between computers, but much of it is.

CCATP #696 – Bart Busschots on PBS 123 of X — Backing up and Syncing Dot Files with Chezmoi (8/22/2021) by podfeet

In this week’s episode of Programming By Stealth, Bart Busschots continues his instruction on how to use the open source tool Chezmoi to manage our dot files, those hidden configuration files on our Macs. In this installment, Bart teaches us how nearly effortless it is to sync our Chezmoi-managed dot files up to a private repo on GitHub. Seriously, it’s like 2 steps.

Bart then teaches us how Chezmoi supports templating. When Bart started to describe it, I said, “Oh! It’s just like mail merge in Microsoft Office!” He laughed, and said he hoped I would say that.

With Chezmoi, let’s say you have your email address in a bunch of your dot files, and you need to change it to a different address. If you use Chezmoi’s templating feature, you can create one file with your email address and in every dot file you reference that address, and only have to change it in one place. Bart walks us through a couple of worked examples to help us see exactly how it works and get a little practice.

The next episode of Programming By Stealth will end this mini-series within a series, and if Bart’s work manages to finally slow down to where he can get some good thinking time, we should start up learning about PHP shortly after that.

CCATP #695 – Bart Busschots on PBS 122 – Managing Dot Files with Chezmoi (8/8/2021) by podfeet

In our previous installment of Programming By Stealth, Bart introduced us to Chezmoi, an open source tool to help us manage dot files, those hidden configuration files that get created on our Macs. Configuration files contain information about how we like our Macs configured, including where to access our ssh keys and our preferred command line editor and more. If we move between computers it would be nice to have the same configuration, or if we do a clean install it would be great to be able to have these dot files in place on our newly-formatted machines.

He teased us last time though but just introducing us to Chezmoi and not letting us do much. In this installment he lets us take Chezmoi out for a spin. We edit an environment variable to set our preferred text editor, and then use Chezmoi to talk to Git to add and then commit those changes. Along with more changes and actions with Chezmoi, Bart works hard to cement the terminology of Chezmoi because without it, it’s easy to not realize what Chezmoi is doing under the hood and it could cause problems in the future.

CCATP #693 – Bart Busschots on PBS 121 of X — Managing Dot Files and an Introduction to Chezmoi (7/23/2021) by podfeet

As we’ve become nerdier while learning from Bart, we have started to add hidden configuration files to our Macs and PCs. On the Mac, these configuration files hidden by default by putting a dot in front of them, and hence they are called dot files. Maybe you’ve stored your ssh keys, or in our Git series you created a user-level gitconfig file, or perhaps you’ve installed VS Code or Sourcetree which also add hidden configuration files.

In this installment of Programming By Stealth, Bart explains the problem to be solved of how we manage these configuration files if we use multiple computers or migrate to a new computer or do a nuke and pave. He lays the groundwork for why he loves the dot file manager called Chezmoi from chezmoi.io.

The installment is a bit of a tease because after learning why we want to have a dot file management tool and why Bart favors Chezmoi for the job, he only lets us install it and run two commands before he says, “And next time we’ll start to use Chezmoi.”

CCATP #692 – Bart Busschots on PBS 120 – Ignoring Files in Git (7/10/2021) by podfeet

A few weeks ago I told Bart off the air that when he was done with his mini-series within a series all about the version control system Git, I’d like a few minutes with him offline so he could explain how to ignore files in Git. I knew there was a way to do it but he hadn’t covered it so I assumed it was just something quick he could explain to me. His reaction surprised me, he said, “D’oh!” because he realized that this is a very important part of using Git and that he would definitely dedicate an installment to it.

So this week Bart teaches us how to use .gitignore to tell Git not to track changes to files and folders. He explains that there are files your computer or even your code editor may be creating that you don’t want Git to track, and of course there all of the dummy test files we as humans create that would not be something we’d want to share with our co-workers or fellow open source contributors.

I was nervous about using git ignore because I understood it relied on patterns, and I thought that would mean something along the lines of using Regular Expressions, which are kind of daunting. I shouldn’t have been worried, .gitignore patterns definitely don’t require any heavy lifting.

I was really looking forward to this installment and it didn’t disappoint.

CCATP #690 – Bart Busschots on PBS 119 of X — Open Source on GitHub (6/27/2021) by podfeet

As promised, Bart takes us through the final step in our GitHub journey – learning how to contribute to an open source project. He explains three open source scenarios: using someone’s code exactly as-is, using their code with a few customizations of your own, and finally the most interesting scenario, customizing the code and contributing your customizations back to the project.

When he gets to the final scenario, he gives us a way to practice these newly acquired skills, and it’s something he’s wanted to do for a long time. He’s created a gallery for all Programming By Stealth listeners to contribute the work they’ve done in the various challenges we’ve worked in Programming By Stealth. If you have your code from the challenges for Conway’s Game of Life, the number guessing game, the currency converter, the currency grid, the world clock, or the time-sharing clock, we’d love to have you contribute to the PBS gallery to show off your work.

Bart explains that the GitHub Pages he’s created will allow us to fork his code, make our own changes, and then create what’s called a pull request to get them accepted into the official PBS Gallery at gallery.pbs.bartificer.net. I worked through the process for one of my projects and it was definitely a learning experience, which is the whole point of Programming By Stealth.

CCATP #688 – Bart Busschots on PBS 118 of X — JavaScript Apps with GitHub Pages (6/12/2021) by podfeet

In this installment of Programming By Stealth, Bart Busschots teaches us how to use a free service of GitHub called GitHub Pages. This service literally gives you free web hosting for the web apps we’ve learned to make in Programming By Stealth. Bart starts by explaining to us the difference between static and dynamic webpages, and web pages created by static site generators like Jekyll which generates GitHub Pages.

It’s trivially easy to create a GitHub Page from an open GitHub repo (literally three clicks in the interface) but it’s really important to understand what you’re doing when you take advantage of this service. We’ll learn what you can do and what you can’t do and what you could do if you choose to dig deeper into the woods on how to use Jekyll to generate GitHub Pages.

I’m really excited to learn about GitHub Pages and how easy it is to host all of the web apps we’ve created in this series.

CCATP #686 – Bart Busschots on PBS #117 of X – Introducing GitHub (5/29/2021) by podfeet

In this week’s installment of Programming By Stealth, Bart teaches us how to use GitHub as a public repository for our code, or for anything we write for that matter. He reviews why he chose Github, and then we dig right in. He does explain the benefits of using SSH to access Github instead of HTTPS, and if you haven’t set up SSH keys before or you’re rusty on the topic, he includes links to our sibling show, Taming the Terminal where you can learn how to do it.

We create a new repo from scratch in Github on the web with a README file and a license, and then we get to use a command-line version of Github called gh. With gh we pull the repo down from Github, edit the files, commit them locally, and push them back up to Github all from the command line. We then flip the tables and from the command line create another repo directly on Github, create some files, set them up to track, and push and pull again to prove it’s working.

It’s surprisingly easy and simple. Bart teases us with the next episode where we’ll learn how to create a website using Github pages, which will give us a nice place to host our web apps for free. You can follow along with Bart’s fabulous shownotes at pbs.bartificer.net/…

CCATP #685 – Bart Busschots on PBS 116 0f X – Team Git (5/15/2021) by podfeet

In previous installments of our Git miniseries within a series in Programming By Stealth, Bart taught us how to work in Git standalone on one computer, then how to work as one developer with multiple computers. In those installments he taught us the necessary commands and their importance in the Git scheme of things. In this installment he talks about how and where to work with a team in Git. We learn about the plethora of options from free to full enterprise-size Git-as-a-service, and why he’ll be focusing on Github for the future. He explains how important it is to set up conventions for your team (before you start) for things like coding styles, development paradigm and more. There’s no coding in this episode as it’s more philosophical than other episodes.

CCATP #684 – Bart Busschots on PBS #115 of X – The Push & Pull of Git (5/1/2021) by podfeet

When Bart started this mini-series within a series on using Git for version control, he explained that our journey would be in three Phases. Phase 1 was the section where we learned about local repositories, and Phase two was dedicated to learning how to have multiple repositories just for ourselves. In this lesson, we finish up Phase 2 by learning how to push and pull changes from our imaginary desktop to our imaginary NAS to our imaginary laptop and back. I slowed down the class a few times with some confusion I had, but Bart always claims that my confusion often helps other people who might be hung up on the same thing. I enjoyed myself immensely, even when I was confused!

We are about to enter Phase 3 where we will learn how to collaborate with others. We’ll be doing this collaboration using Github, because it’s pretty much the defacto home for most open source projects. When you’re done listening to PBS #115 and studying the shownotes, you might want to get yourself a Github account so you can be ready for the next lesson.

CCATP #681 – Bart Busschots on PBS 114 – Tracking Git Branches (4/17/2021) by podfeet

We continue on our journey to learn how to use Git to do version control as a single person, but this time with multiple devices. As Bart says during this episode, “Who is learning to program here who doesn’t have multiple computers?” We’ve learned how to push our changes to a single separate repo, but we had to always say what branch we wanted to push to what branch on the origin. In this installment, we learn how to tell Git to track our branches so they stay in sync without us having to tell Git every time which branches to push where. We also learn how to make sure our annotated tags get pushed as well by setting a single repo or all Git repos on our computers to push our tags. Bart leaves us with a big tease at the end. We learn how to clone a repo in preparation for having two computers accessing the same code in Git with a primary source acting as the go-between for them.

CCATP #679 – Bart Busschots on PBS 113 of X My First Git Remote (4/3/2021) by podfeet

Last time on Programming By Stealth, Bart introduced the concept of remote repositories, also known as remotes. It was one of those episodes where we learned a lot but didn’t get to apply what we learned. In this week’s installment, we get our hands digitally dirty as we create a bare repository (a repo with no working tree), and declare it to be a backup of our local repo. We learn how to fetch and view remote branches and tags, how to push everything to the remote, and then after making some changes, push them to our remote backup. We’re still in a bit of a sandbox as we do all this on one computer inside a couple of local folders, but the lessons exercise our new muscles to get ready for the big leagues.

CCATP #677 – Bart Busschots on PBS 112 of X – Introducing Git Remotes (3/21/2021) by podfeet

In this next installment in our mini-series on learning Git, Bart Busschots gives us some foundational knowledge on how to work beyond being one person with one Git repository.

He starts by reinforcing what he’s explained before, that Git is a peer-to-peer technology, which is hard to wrap your head around if you’re used to client-server relationships. He walks us through three scenarios to explain how every “actor” gets a repository and why. Then he explains the jargon of “local” vs “remotes”. It’s at this point that my head started to hurt, but Bart claims this is where I’m value-added to the podcast. I ask all the questions you might have, and I suspect many more than you have. Bart sticks with me and makes sure I fully understand.

CCATP #669 – Bart Busschots on PBS 111 of X – Stashing Changes (1/31/2021) by podfeet

In this installment of Programming By Stealth, Bart teaches us how Git can help us when we forget to switch to the correct branch before starting to make changes to our code. We’re only human, and we will forget, and Git’s stash command allows us to set our changes aside, switch to or even create and switch to the correct branch and then apply our changes. His explanations and repetition in the exercises really cement the knowledge. As a bonus tip, he teaches us how to make shell variables inside the Terminal which will help us with some of the repetitive typing in the future.

CCATP #668 – Bart Busschots on PBS 110 of X – Merge Conflicts (1/16/2021) by podfeet

In this installment of Programming By Stealth Bart teaches us how to deal with conflicts in branches of our code. He has been purposely only changing one thing at a time before now, but it’s time to face the reality of when two branches change the same line in the same file. I’ve been terrified of this topic for a long time, but Bart shows us how easy it is to see exactly what the conflict is, how you can back out of merging if you make “a pig’s breakfast” of it, and how to resolve your conflicts without fear. It’s not nearly as terrifying as I thought it would be.

CCATP #666 – Bart Busschots on PBS 109 of X — SemVar & Structured Commits (12/29/2020) by podfeet

We continue our mini-series within a series learning the version control system Git. We learn two methods to enhance our branching strategy. First, we’ll walk through some basic principles on how to number our released versions of our code. From there we’ll explore three types of changes that would cause a change in our release version: fixes, new features, and breaking changes. Each of these types of updates to the version of our code can be articulated with Semantic Versioning, also known as SemVer. This numbering convention informs users of our code on the meaning of each release. Finally, we marry these concepts by creating meaningful commit messages using another convention called Conventional Commits. Not only can a user of our code see at a glance what happened in a specific commit, documentation can be auto-formatted to explain the commits.

There’s not a lot of hands-on in this lesson but as a structured person, I really appreciate these conventions and why they’re important.

CCATP #665 – Bart Busschots on PBS 108 of X — Merging & Tagging (12/18/2020) by podfeet

In this installment of Programming By Stealth, Bart Busschots continues on his series within a series explaining the version control system Git. We advance in our branching strategy by working several commits on our dev branch and then learn to use a merge commit to bring only the final commit into the main branch, leaving the half-working intermediate commits to exist only on the dev branch. This process illustrates the need to learn about tags, both light-weight and annotated. Once we understand how these tags work and their importance, we evolve our PBS branching strategy one step further.

CCATP #663 – Bart Busschots on PBS 107 of X – Branching Basics (12/2/2020) by podfeet

This week in our miniseries on learning the version control system Git, Bart dips our proverbial toe into branching. Branches allow us, as developers, to work on bugs or feature enhancements in a separate place from our stable code, and only merge the code back in when the bugs are squashed or the features are stable.

We don’t get much practice in this instalment, but rather Bart talks to us about the idea of having a strategy for when to branch and how to name your branches in order to prevent chaos. He gives us some simple and yet difficult to adhere to strategies and then takes us through more rigorous strategies that will actually be easier to follow. He emphasizes that he’s not telling us which strategy to follow, but rather to have a strategy.

We do a few small examples from the command line, but we get to open our Git GUI clients, like GitKraken and Sourcetree and see how the commands we’re typing are graphically represented in the clients. It’s a good illustration of what Bart has been promising us – that the GUI clients are doing exactly what the command line is doing.

CCATP #661 – Bart Busschots on PBS 106 of X — Time Travel with Git (11/20/2020) by podfeet

As we continue to learn Git from the command line for version control, Bart teaches us some tricks to travel through time. First he shows us how to view more compact Git logs so we can just see a shortened hash and the first line of our commit message. Then he shows us how to pick out a single commit from the past and see what changed. Then he shows us how, with surgical precision, we can go back in time and get a single file or even just the changes from a specific commit and bring them forward in time. It sounds head bendy but I could immediately see the usefulness of going back in time and grabbing some code that was working well and bringing it forward.

CCATP #659 – Bart Busschots on PBS 105 – Seeing the Past with Git (11/7/2020) by podfeet

In this installment of Programming By Stealth, Bart takes us on a time traveling adventure with Git. By using commands like git diff we can see changes over time, but we can actually see older versions of the code in a couple of ways. Using the archive command we learned out to pull just the files at a certain point in time (without the history) and the more terrifying checkout command that creates a “detached HEAD”! Bart even explains why that phrase was introduced and what it actually means. This was a fun lesson and a good foundation for what we’ll learn next time, when we’ll learn about stashing and branching to control the past and future.

CCATP #658 – Bart Busschots on PBS 104 – Tracking Changes in Git (10/24/2020) by podfeet

In our next baby step in learning to use the version control system Git, Bart teaches us how to track changes. We start by doing a bit of housekeeping, especially for Mac users to set Git to always ignore those pesky .DS_Store files. We learn how to stage and then commit a simple change, then we stage and commit multiple changes and even learn to see the differences in our staged files from the database all from the command line.

While we all think we’re capable of making one structural change and then committing our changes, Bart knows that it isn’t going to happen. But there’s still a way to follow Helma’s advice to “commit early and commit often”. Bart teaches us how to divide the changes we inevitably make into separate commits with separate comments so we can figure out what we did later.

I enjoyed this installment because I could tell it was laying a very important foundation of understanding. You can follow along with Bart’s famous shownotes at pbs.bartificer.net/…

CCATP #656 – Bart Busschots on PBS 103 of X — Getting Started With Git (10/11/2020) by podfeet

After some quick revision from the previous episode, Bart explains how Git commands work with their subcommands. We start by looking at how to configure Git and the differences between local, global and system-level settings. Then we create our very first repo with an exciting README file, and we commit the file to our repo. It’s a fairly simple lesson while laying down a good foundation for all future work.

CCATP #654 – Bart Busschots on PBS 102 of X – Introducing Git (9/27/2020) by podfeet

In our last Programming By Stealth we learned about the concept of version control, and the evolution from client/server version control to peer-to-peer version control and the creation of Git. In this installment we start learning the fundamental concepts of Git. We learn about the database, the working copy, and the index and understanding the difference is critical to effectively using Git. We also dig into the Git database and begin to learn the terminology inside it, which oddly uses normal English words but those words might not mean what you think they mean. We gain an understanding of why Git uses SHA1 hashes but not for encryption. We start to get into the power of Git as we learn about commits, staging, stashes, and tags.

We didn’t get to play with Git yet but the challenge is to install Git and if you want the extra credit, choose and download one ore more Git GUI clients.

CCATP #652 – Bart Busschots on PBS 101 – Introducing Version Control (9/12/2020) by podfeet

In this turning of the century episode of Programming By Stealth, it’s time to take on a new subject: version control. As Bart explains in this week’s episode, version control allows you make changes in your code and roll the changes back. This gives us the freedom to experiment and if an idea doesn’t pan out, get back to where we started. Bart explains some of the origins of version control, starting with client server systems and then tells us how peer-to-peer version control has become the standard from industry to open source.

Bart explains how the version control system Git was created and how it proved itself worthy of becoming the standard. There’s not a lot of heavy lifting in this episode but Bart promises that future episodes will be challenging as we get into how to actually use Git.

CCATP #651 – Bart Busschots on PBS 100 of X — Time Sharing Challenge Solution (8/30/2020) by podfeet

Bart and Allison holding up their cake100th Programming By StealthIn this positively delightful episode, Bart and I celebrate 100 episodes of Programming By Stealth. When we hit 99 installments, Bart declared that for 100, there should be cake! So I got Bart’s darling beloved to deliver him a piece of cake right as we started, and Steve delivered one to me. To say that Bart was surprised and delighted would be an understatement!

The actual episode was an opportunity for Bart and me to share our respective solutions to the challenge from PBS 96, which was to create a web app that would allow a podcaster to send a time of their choosing to another podcaster. He didn’t put a lot of restrictions around it, so our solutions are completely different.

I begged to go first because I told him that going after him is like being the comedian who had to go on after Robin Williams. He replied that he wanted to go first for the same reason! He explained that I took on a much harder task than he did. In his solution, he picks a time in his own timezone and then copies a URL from the site and sends it on to the other people and they see the time he chose in their own browser. He did add a few bells and whistles beyond that but it’s the basic idea.

My solution allows the user to enter two timezones of their choosing and then drag a slider to shift time to see how convenient it is for the other person, and then copy the time. I was quite pleased with my user interface, and Bart even borrowed one of my ideas to use a utility called Bootstrap Collapse to show and hide certain page elements. To be doing something that Bart wants to emulate warmed my little heart.

A fun fact about our solutions is that Bart worked on his for an entire 3 days, and I worked on mine for two months on and off. I’m still proud of what I accomplished!

PBS Listeners – Can We Interest You in a Cup of Taming the Terminal? (7/12/2020) by podfeet

Hi, Programming By Stealth listeners! I wanted to let you know that Bart and I are taking a bit of a break from Programming By Stealth, the need for which happens every summer but for some reason catches us both unawares each year. Bart works in education and the summertime is the only practical time to make huge changes to the computer systems underlying said education. As you might guess, this year presents even more “interesting” challenges.

However, Bart and I are not lying down on the job, and we have something to offer you while you await the next installment of Programming By Stealth.

Five years ago Bart and I started a series called Taming the Terminal which ran for 35 of n episodes. Like Programming By Stealth, he made the ending indeterminate. He did this because while he accomplished the teaching he set out to do, he knew that things would change in the macOS terminal and new advances would be the opportunity for new episodes.

After a year hiatus, he brought us episode 36 in late 2016 where he taught us about screen which allowed you to SSH into servers and start processes that would continue even while disconnected. In mid-2017 he taught us about SSH agents to address a change in El Capitan that made you have to enter your passphrase to a server more often. This affected what we were taught in TTT30 about SSHing into our servers.

It turns out that Red Hat deprecated screen recently and instead there’s a tool called tmux that does everything screen used to do and more.

This week Bart and I recorded installment 38 of n in which he taught us the basics of tmux that replace screen‘s functionality. And in two weeks we’re going to publish the second half of the tmux story where he will teach us the other cool stuff it can do.

If you are an avid listener to Programming By Stealth, then I’m sure that Taming the Terminal will be a fun podcast for you. You can easily jump in right now to episode 38 or you can start at episode 0 and listen to all the back catalog.

As always you can find Taming the Terminal in your podcatcher of choice, and this week’s episode is also included in the full Chit Chat Across the Pond feed.

CCATP #643 – Bart Busschots on PBS 99 of X – Building with Classes Part 2: Is-A (6/28/2020) by podfeet

This week Bart Busschots brings us the penultimate JavaScript installment of Programming By Stealth as he brings us part 2 of building with classes. This wraps up our third look at Object Oriented programming in JavaScript. We learn about the concept of inheritance, and how it allows us to build classes that inherit attributes and functions from parent classes. This allows us to eliminate code duplication which Bart explains is called a “bad smell”.

CCATP #642 –– Bart Busschots on PBS 98 — Building with Classes Part 1 — Has-A (6/13/2020) by podfeet

In this episode of Programming By Stealth, Bart explains one single concept, that of “Has-A”. This is part 1 of 2, where next time we’ll learn “Is-A” which is about inheritance. These both sound like odd terms but they’re part of what makes object oriented programming so powerful. Bart spends 90% of the time going through a worked example which not only explains how classes can have instances of other classes as properties, but also how classes can be more specific versions of other classes. Along the way, I think he achieved his goal of cementing the foundation of getters and setters and Class functions and Instance functions. We’ll see if I can use them in anger on the homework though!

CCATP #640 – Bart Busschots on PBS 97 — Class Data Attributes & Functions (5/31/2020) by podfeet

I’m not going to lie to you guys, this episode of Programming By Stealth was pretty rough for me. It builds on the foundation Bart laid in PBS 95 where he introduced Getters and Setters and it was pretty clear that this previous lesson had not sunk in for me yet. I’ll definitely have to go back and study PBS 95 a couple more times and get a chance to practice this Getter/Setter concept before the penny will drop. Hopefully you understood it better than I did the first time through!

In any case, in PBS 97, we extend that knowledge to learning about class data attributes and functions. We’ll learn the “static” nomenclature, which is used to mark attributes and functions as belonging to the class rather than the instances of a class.

Bart spends most of the lesson on a worked example using emoji to create what he playfully calls a Nerdtouche, as a head nod to the cartouche used by Egyptian Pharoahs. And yes, he manages to work the poop emoji into this lesson.

This installment of Programming By Stealth is a solutions show all about the clock assignment from PBS 92. Bart’s been quite busy this week designing an entirely new distance final exam system for the university where he works so he asked if I’d take on half of the content by presenting my solution to the clock challenge. I have had an absolute blast on this assignment so I gladly accepted. I walk through my approach and some of the challenges I met along the way, and then Bart complements mine by talking about a few things he did quite differently. We both had a great time and I think Bart even learned something from me at one point.

CCATP #637 — Bart Busschots on PBS 95 of X — Better JavaScript Class Attributes (5/2/2020) by podfeet

This week Bart explains how to give our JavaScript classes better data attributes via a very powerful JavaScript feature: getters and setters. On my first read through the notes for the episode, my head was spinning a bit, but Bart explains this so well using concrete examples (like a circle with a radius) that I think he got it through to me. When I told him up front that I struggled a bit when reading the shownotes, he said that this is the “pointy end” which I think meant that it was a difficult concept so I felt a little better about it.

In the end it made a lot of sense and I see the reason for the tools he explained.

I highly recommend you read Bart’s terrific tutorial shownotes at pbs.bartificer.net/pbs95 as you listen along.

Allison diagrams classes constructors and instances
My Diagram Explaining Classes, Constructors, Objects and Instances

In the early days of Programming By Stealth, Bart tried to explain JavaScript classes, objects and instances. He talked about it in Installment 17 before ES6, and then took another run at it in installments 27-31. But it never felt to Bart like he had explained it in a way that made it clear.

In installment 94, Bart finally nails it. I told him the shownotes for this installment might be the best he’s ever done. Everything he explains is clear and concise, the examples are superb, and we get to say Hoonyaker a lot. Instead of being frustrated and confused, I was smiling through all of it because I finally get it. I also told him that I feel far less stupid than I did before because I always thought it was my failing that I didn’t get it. I enjoyed this so much I drew Bart a picture of what he’d taught and he said I nailed it!

CCATP #632 – Bart Busschots on PBS #93 – Encapsulation with JavaScript Objects (4/5/2020) by podfeet

In this episode of Programming By Stealth, Bart takes us through the last “hat” that JavaScript objects can wear: encapsulation. As Bart walks us through the problems encapsulation solves using a funny NosillaCast-specific example, he shows how the code becomes reusable and sharable with encapsulation, and even more readable.

CCATP #630 – Bart Busschots on PBS 92 — Currency Grid Solution (3/20/2020) by podfeet

CCATP #630 for March 14, 2020, and I’m your host, Allison Sheridan. This week our guest is Bart Busschots with PBS 92 of X in which he walks us through his solution to the assignment from PBS 89 to create a grid of currency conversions.

He doesn’t go through his code line by line, but rather gives us the big picture of his process. Most of the time he spent on the solution was actually in refactoring his code because he decided to preload the data rather than fetching it repeatedly on-demand. I loved it when he referred to his original work as “Organically-grown Weasley-kind of code”.

He also explains how he used both coercion and assertion to do his error handling and why. Eventually he got to start working on the grid and he walks us through how he cracked that problem. It was great fun as always and we have a new, six-week challenge to build a world clock.

CCATP #628 — Bart Busschots on Creating Automator Quick Actions (3/7/2020) by podfeet

This week our guest is Bart Busschots with an installment of something he’s calling Programming By Stealth-adjacent. It’s not part of the regular series of Programming By Stealth, and yet it’s not technically very “light” in terms of the chit chatting. Since neither podcast is the right place for it, I’ve decided to put it in both podcast feeds to be wrong twice.

Bart walks us through how to create Quick Actions with Automator (also known as Services) to do some simple but very useful text manipulations using a smidge of JavaScript. Even if you don’t want to write these Quick Actions yourself, you can download his services from his Github repo where he’s put them up as open source: https://github.com/bbusschots/macos-quickaction-text.

CCATP #626 — Bart Busschots on PBS 91 of X — JavaScript RE Objects (2/22/2020) by podfeet

Bart takes us through the penultimate hat JavaScript wears and that’s Regular Expressions. Luckily since we haven’t talked about REs in ages, he reminds us of the syntax for Regular Expressions literals in JavaScript first and then he takes us through three common uses for Regular Expressions. We joked around during this episode at how many times I said, “That makes sense!” Bart said it was music to his ears, and I say this was a very intuitive lesson considering how arcane Regular Expressions are in their syntax.

CCATP #624 — Bart Busschots on PBS 90 of X — JavaScript Wrapper Objects (2/8/2020) by podfeet

Hope you enjoyed getting the little extra Tidbits episode this week. In this installment Bart continues our on-going mini-series looking at each of the proverbial hats JavaScript objects wear. Bart explains the concept of JavaScript wrapper objects that allow you to access properties of otherwise property-less primitives. It’s pretty magical and I only got lost for a little while as we brushed the cobwebs off my memories of prototypes and such.

PBS Tidbit 1 of Y — Display Values are not Data! (2/8/2020) by podfeet

This is not a normal episode of Programming By Stealth, it’s what Bart Busschots is calling a PBS Tidbit. Listener @lbutlr pointed out to Bart and me on Twitter that Bart’s math was wrong in his solution to the challenge he posted in PBS 89. The assignment was to produce currency exchange rates for a variety of currencies, based an amount for the base country. That is, 10,000 Japanese Yen is how many Euro, Canadian Dollars and New Zealand Dollars.

The problem was that if you chose large amounts (like 10,000 Yen), Bart’s math fell over in a heap, returning 100 for all countires or with South Korean Won, most countries returned 0.

Instead of being incensed or embarrassed at having made a mistake, Bart dug in, figured out what went wrong, and then wrote up his path to discovery and the tools he used to fix the mistake. He made it a teachable moment. He decided to call this PBS Tidbit 1 of Y because this probably won’t be the last time this happens.

After Bart finished, I talked about another thing @lbutlr told us and how I’m trying to implement it in my challenge solution. I’ll be writing that up once I get it figured out.

CCATP #622 — Bart Busschots on PBS 89 of X — Currency Converter Challenge (1/26/2020) by podfeet

In this week’s installment of Programming By Stealth, Bart explains his new plan for both the content of PBS and the way the shownotes are created and presented to you. Bart has noticed that because we put a challenge solution and new content into the same show, the solution gets short-changed. That’s a shame because there is so much he can teach by explaining the “whys” behind the design of his solutions.

The new plan is to have the challenge solutions be standalone shows, and then the new content will be standalone shows as well. We’ll be having more time to do our challenges with this new plan as well. I’m excited about this new plan because I’ve enjoyed the extra time we’ve had with our currency converter challenge, allowing us to enhance our solutions and be more creative.

This week’s installment then is a review of why he made certain decisions on how to solve the last Programming By Stealth challenge, which was to add the ability for the user of our currency exchange web app to enter a value to be converted to the different currencies.

Bart is also completely rearchitecting all of his web presence, including his Programming By Stealth show notes. His new online presence will be at his site, bartficier.net and PBS will now be at pbs.bartificer.net. That link is actually to a GitHub page. I know that sounds crazy and Bart is going to tell us more about it, but it will allow him time to be much more creative and spend less time faffing about as a system admin. This is very much a work in progress and we expect a few learning opportunities along the way!

CCATP #619 — Bart Busschots on PBS 88 of X — DOM & jQuery Objects Redux (12/14/2019) by podfeet

Bart is nearing the end of his mini-series recapping al of the different hats JavaScript objects wear, doing a lot of redux to cement the concepts that have been spread over so many lessons. He takes a really interesting approach this week to his teaching. He explains a concept and then instead of having a contrived example, he shows us exactly how that concept works in action in his homework solution from PBS 85. His solution to the homework assignment is, of course, beautiful and elegant. Beautiful he gives credit to Bootstrap, elegant he would probably give credit to jQuery.

I am really enjoying these redux segments because they cement things that were still wobbly, or perhaps even gone from my memory. Each time through I’m finding I understand how to even categorize the information in my brain. I explained to Bart that I think he’s actually changing the way my brain is wired now.

CCATP #617 – Bart Busschots on PBS 87 of X — JavaScript Iterators Objects & Generator Functions (11/30/2019) by podfeet

I’m not going to lie, this episode of Programming By Stealth with Bart Busschots was a bit head bendy. Bart explains JavaScript Iterator Objects and Generator functions but without his excellent examples I’m certain I would never have been able to get the concepts to even slightly congeal in my brain. Iterator Objects and Generator functions are some of the joys of ES6 and have great value.

That value is demonstrated in the succinctness of the code Bart writes for us to create a Fibonacci series in a beautiful web form. That work, by the way, is a bonus challenge if you’re done with your homework from the previous episodes. As you listen along, if you hear us yelling “spoiler alert” and making alarming noises, that’s when Bart’s solution to the challenge is about to be described. It’s a rare instance where I actually let you have one chapter mark in Programming By Stealth so you’ll be able to jump back to the solution after you’re done with your own solution.

CCATP #615 – PBS 86 of X — JavaScript Function Objects (Redux & Update) (11/14/2019) by podfeet

This week Bart Busschots takes us back through JavaScript function objects, explaining the three different ways to define a function. It was great to have them all together to refresh our memory. He explains how only one method is hoisted, which lead him to explain the medieval history reference of “hoisted by your own petard”. There was a part where he talks about wearing tutu, but Only a podcast with Bart could go that route! We went from there to function scope and enjoyed some time going through advanced arguments which is way more fun than it sounds. Things took a turn for the weird when Bart explained fully-simplified fat arrow syntax as all common language conventions disappeared. Also we talked about Bart wearing a tutu. You’ll have to listen to learn how that was actually in context.

CCATP #613 – Bart Busschots on PBS 85 of X — Objects as Arrays in JavaScript (Redux & Update) (11/3/2019) by podfeet

Bart continues his redux and new information by circling back through Objects as Arrays in JavaScript. I don’t know about you, but I get a lot out of the redux episodes because it cements in place concepts that were a bit wiggly before he goes through it again. The one new concept he goes through is Array Destructuring which sounds ominous and destructive but which allows us to dive into arrays and create new and more interesting arrays.

Bart also debuts a new way he’s providing the content for the lesson. If you still want to download the zip file with all of the example files, you can, but you can also view the source code and view the HTML in a browser with a Github link. By the way, the zip file is now living on a content delivery network. This is important to note if you’re coming in from Safari with the more recent security updates because it will prompt you to agree to downloads from this new URL.

CCATP #611 – Bart Busschots on PBS 84 of X – Objects as Dictionaries in JavaScript (Redux & Update) (10/20/2019) by podfeet

Bart has been noticing that there are a few key features in JavaScript that haven’t ever really congealed for me and is circling back in hopes of firming them up. The other reason he’s going over these topics is that new options have been created since we first covered them. The first of these subjects is objects as dictionaries. I confessed to him recently that I’ve never successfully done a for loop on my own yet, so we slow down a bit during that part but we speed up again into what are actually more challenging topics. We had a lot of fun doing this episode (even when I was stuck!)

Bart’s tutorial shownotes can be found at pbs.bartificer.net/…

At the end of the show, I suggested a palate cleanser, which is a feature of his Security Bits segment he does for the NosillaCast. I found an awesome tweet by developer Sarah Dresner aka @sarah_edo: “Apparently the only cure for jetlag is to make SVG animations of farting rhinos with the new @greensock API 💨”. Of course I had to follow that link, and it was awesome. It is literally an SVG file of an adorable little rhino trotting along and tooting. After Bart and I got off the air we took advantage of the fact that she’d posted the farting rhino on codepen.io so we view the HTML, CSS, and JavaScript to see how she did it. I know this is silly but that’s what makes it so awesome.

CCATP #610 – Bart Busschots on PBS 83 of X Bootstrap Cards (10/4/2019) by podfeet

Bart finishes up our first exploration of Bootstrap 4 with a look at one its most versatile components, the so-called Card. This is one of those components that’s so generic it’s hard to describe, but once you learn about it you’ll start seeing it all over the web. Cards really are ubiquitous!

It’s important to stress that while we’re wrapping up our exploration of Bootstrap 4 with this installment, that does not mean we’ve come close to covering every feature this impressive library offers. Instead, the aim was to cover the big-picture items, and leave you with enough experience to be able to learn the rest independently by reading Bootstrap’s excellent documentation.

CCATP #609 – Bart Busschots on PBS 82 of X – Async & Await (9/20/2019) by podfeet

A quick note here – Dorothy, aka @maclurker in our Slack group has been applying all of her newly-acquired programming skills from PBS to her fabulous PBS Index. She’s now using Mustache templates, Bootstrap styling utilities, and even AJAX with JSON. The result is a beautiful thing to behold, giving us immediate results as you start to search and more. Bart has now made a permanent URL for the PBS Index, it’s bartb.ie/pbsindex.

Since Bart works for a University, summers are not a time of rest and relaxation for the system admin staff, they’re the only time upgrades and maintenance can get done because the students are gone. In the future, we think we’ll plan our summer hiatus for Programming By Stealth rather than it taking us by surprise each year.

In any case, we’re back with a new installment where we attempt to dust off Allison’s brain and learn about two new promise-related keywords, async and await. Both of these keywords were actually added to the core JavaScript language, so this doesn’t happen that often.

With async and await, we can actually get away from doing promise chains and create much more readable code while still being able to control parallel and in series tasks. Bart had to drag me along a bit in this one but I saw the beauty of it when we were done.

In this installment of Programming By Stealth, Bart teaches us how to use Promises, with a capital P to get promises when we already know the value we want to supply. That sounds funny but it will make sense in context. Then he shows us how we can control parallelization of promises using Promise.all(). It’s a very sensible lesson, and not brain bendy at all. (I really like those.)

In the very first Programming By Stealth supplemental episode, I interview Dorothy Rendon, the programmer behind the PBS Index. If you haven’t seen it before, it’s an index that Dorothy has created for the Programming By Stealth students to helpt them find key topics in Bart Busschots’s fabulous tutorial shownotes.

We’ll first get a little background on Dorothy and then move on to learning how she used to produce the index, and how her advanced learning in Programming By Stealth allowed her to simplify the process and make it prettier, using JSON, Bootstrap and mustaches. I didn’t want to leave you without something in your Programming By Stealth feed while I’m on vacation and I think you’ll find it a lot of fun.

Bart Busschots (successfully) explains the concept of JavaScript promise chains. It’s a rough ride because of the subject itself, but he gets us there through his care and detail in explaining the concepts and of course his great examples. When he’s done, you’ll know how to chain promises together, you’ll understand what data is passed through, and you’ll understand why he says, “Don’t have unhandled rejections, it’s just not nice.”

CCATP #595 — Bart Busschots on PBS 79 — Introducing JavaScript Promises (5/31/2019) by podfeet

Bart has been promising us Promises for ages now and he finally fulfills his promise by explaining thenables. Promises are a tool to get us out of “callback hell”, which we experienced a while back. I think he made us suffer through that so we’d appreciate Promises. In this episode he shows us the beauty and elegance of the concept but leaves us wanting more. Bart spent a lot of time trying to get the shownotes and his narrative to take this rather abstract concept and make it concrete, and I think he did a grand job of it.

Bart Busschots and I both had a great time doing the challenge this week. In this week’s installment Bart takes us through his homework not in a detailed step-by-step method, but rather he goes through some major structural ways he created his code. He digs deep enough to explain why but it’s a great lesson on building code that’s easier to debug and more fun to write. I got to be the tester of his code, and as I suggested improvements he decided he needed to use Bootstrap Popovers. He walks us through how they work and I have to say they’re really slick. Then he introduces us to a super intuitive JavaScript library called is.js that solves will simplify our code. I asked Bart if he could back up 2 weeks and show me is.js BEFORE I did last week’s homework!

Bart Busschots starts this week’s episode with a great refresher on what a callback actually is (because I have remained mystified by the term). He starts with simple examples and then shows us how we’ve been using callbacks all along and just didn’t realize it. Then he’ll walk through the challenge solution and the extra credit. He shows us how there are two paths to “callback hell”, one through nested AJAX calls in parallel, and one with them in series (which sounds worse than it actually is. The challenge for next week is super open-ended which terrifies me but I’m sure it will be fun.

It’s a great refresher on the methods he’s taught us in the past, all rolled together with our newfound skills with Mustaches and templating.

I learned so much that I didn’t know about what you can see in a URL.

CCATP #587 – Bart Busschots on Programming By Stealth 74 of X (3/24/2019) by podfeet

In this week’s Programming By Stealth, Bart Busschots teaches us the last two concepts in Mustache, one of which is a real head bender and for me at least, the second was almost as hard. The first is how you can add an optional third argument to a Mustache view which is actually a function within a function. It’s a very meta concept. The second is the use of Mustache Partials which are templates within templates. I expect you’ll follow along faster than I did but I think I got there in the end!

CCATP #585 – Bart Busschots on PBS 73 – Mustache Templates (3/10/2019) by podfeet

In this installment of Programming By Stealth, Bart Busschots teaches us about Mustache Templates. Mustache Templates are a library that allows you to input any string and output a string. Unlike the template tag for HTML5, Mustaches are not restricted to HTML snippets. Mustache isn’t the only game in town but it’s Bart’s favorite. I found this lesson fairly confusing along the way but when I got to the very end I think I understood it all! There was a key point in his instruction when he said to think of this as being like Mail Merge where you have a form letter and then a separate file that has the info that gets plugged into the form letter. Once he said that it became much more clear to me. Hope that little hint helps you too!

Last time Bart teased us that we were going to learn about the template library called Mustache, but he realized that he needed to teach us about vanilla HTML 5 Templates first. He starts by showing the problem to be solved: how messy and error-prone it is to create HTML elements using jQuery. Then he shows us how templates allow you to create multiple elements via cloning of the templates. The syntax is quite annoying, but I think once we get used to it, it will be pretty easy and efficient to use.

He does a great job of reminding us of things we’ve learned, in some cases more than a year ago, and showing how they were applied for this particular problem. I’m quite proud of one little thing I discovered that Bart didn’t know had been introduced in HTML 5. After he’s done walking through the challenge, he introduces Bootstrap Spinners. Spinners are a visual indicator to the user that some operation is going on that will take some time and let them know that things aren’t just broken.

We’ll shift gears a bit away from web pages to web apps as we explore the usage and code behind Bootstrap Modals and Toasts. It’s a combination of HTML, Bootstrap for styling and JavaScript for actions so it flexes all of our programming muscles.

We wanted to give a special shoutout to Caleb Fong, aka @GeekoSupremo for posting a link in the Podfeet slack to a fabulous cheat sheet for a ton of programming APIs.

He explains the differences between dropdown and selects in HTML, and how there’s two different kinds of dropdowns – menus and navigation. The descriptions of how to make the Bootstrap dropdowns takes a while, but when he puts the pieces together, the code is quite sensible.

With any luck at all, I think I have added chapter marks to the show to let you jump from the intro to the homework challenge and then to the new material. If this provides value to you, it would be swell if you sent me a note in some way about it.

He shows us how to take a little control, how to take a lot of control and how to take supreme control. That last bit scared me when he introduced it but he does a fantastic job of breaking down the building blocks for us.

Chit Chat Across the Pond this week was Programming By Stealth installment 65 of X. This time Bart takes us through Bootstrap Input Groups. These are really cool. Think about a form that has information you have to fill in, but you’re never sure what they’re asking for. If they ask for money, what currency do they mean? Are you supposed to include the numbers after the decimal or not? With Bootstrap input groups you can put little symbols or words before or after the input field to make it obvious. As with all things Bootstrap, it’s not something that can’t be done in HTML, but it’s so much easier to make them pretty and elegant without being a designer.

CCATP #564 – Bart Busschots on PBS 63 of X — Bootstrap Buttons (9/23/2018) by podfeet

This week in Programming By Stealth, Bart Busschots and I spend a fair amount of time going over the homework challenge from PBS 62. The nuances combined with some refresher on how the pieces fit together was something I really needed so hopefully I wasn’t alone. The new part of the episode is dedicated to the all-important Bootstrap Button. We’ll learn how to turn things into buttons and why you might want to do that, and we’ll learn how to make Button Toolbars which are really slick and pretty. We don’t have new homework for this week but if you’re like me you need time to properly finish last week’s homework.

CCATP #563 – Bart Busschots on PBS 62 of X — A Basic Bootstrap Form (9/15/2018) by podfeet

This week’s Programming By Stealth was great fun. Bart Busschots teaches us how to create a web form using the Bootstrap classes to do the job. He explains how Bootstrap literally insists that we make our code accessible, and how sensible it is to just that. We learn the importance of Form Groups, and how Checkboxes and Radio Buttons are a slightly different type of input to a form and so have their own Bootstrap class. It’s great fun and the challenges look like fun too.

At the end of the episode I added what Bart likes to call a Palate Cleanser. I’ve been following a woman named Samantha Ming on Twitter and samanthaming.comw where she posts fun little CSS and HTML tricks. I learned how to make the caret on an input field blink in pink, and how to make regular HTML text on a web page be editable.

CCATP #561 – Bart Busschots on PBS 61 of X — Bootstrap Jumbotrons & Badges (8/30/2018) by podfeet

In this week’s installment, Bart explains how to create two simple Bootstrap components, the Jumbotron and badges. A Jumbotron is a show-case area at the top of a website’s front page that shouts out the site’s main message and usually has a call to action. Badges are the little bubbles next to titles or within buttons that contain extra information. Often they contain a number, such as number of unread messages, or a short phrase like “New!” or “Best Value”. It’s a pretty easy lesson and the homework looks fun too as we figure out how to add badges to count the number of open alert windows and add a Jumbotron to our work.

CCATP #556 – Bart Busschots on PBS 59 of X — More Bootstrap Breakpoints (7/28/2018) by podfeet

Bart takes us back to Bootstrap content, now that we know all about breakpoints. He never told us when we were looking at things like margins and float and the display tag that they are also breakpoint-aware, because we didn’t know about breakpoints yet. It’s an easy lesson and it’s great fun to learn more about how responsive design is done with Bootstrap.

CCATP #555 – Bart Busschots on PBS 58 of X – Bootstrap Breakpoints (7/15/2018) by podfeet

In this week’s installment of Programming By Stealth, Bart Busschots explains Bootstrap breakpoints. Breakpoints allow the designer to define how a web page reacts depending on the size of the viewer’s screen. He explains how through some very simple Bootstrap classes, we can allow a semantic tag to be in the “correct” order for screen readers and search engines, and yet have the layout be visually appropriate across all screen sizes.

CCATP #553 – Bart Busschots on PBS 57 of X – the Bootstrap Grid (6/30/2018) by podfeet

Things take a turn for the mind-bendy in this installment about Bootstrap as Bart Busschots explains the Bootstrap Grid. He teaches us how containers have rows, rows have columns and the number 12 is really important. In the end, he leads me to understanding but it was a bit of a bumpy road getting me there.

We finished learning the Bootstrap Utilities last time so this time we get to start learning about continue to learn about Bootstrap moving on from the Utilities into Bootstrap Content. Content is kind of an odd word; it means Bootstrap’s styling of regular HTML tags for things like headers, paragraphs, lists and tables. We have a lot of fun playing with our recipes in this episode, learning how to easily style them to be much prettier. Bart’s fabulous tutorial shownotes are at pbs.bartificer.net/…

CCATP #537 – Bart Busschots on PBS 54 – More Bootstrap Utilities (5/19/2018) by podfeet

In this week’s episode of Programming By Stealth, Bart Busschots takes us through the last bit of the Utilities for Bootstrap 4. We’l refer to the WABAC Machine (kids, ask your parents about Sherman and Mr. Peabody) to installments 8 and 9 comparing positioning with CSS vs. Bootstrap. Thenwe’ll learn about sizes and float utilities, Flexbox utilities, and Screen Reader utilities. It’s great fun and of course Bart has his excellent companion tutorial at pbs.bartificer.net/… and you can find Dorothy’s awesome index of all things Programming By Stealth at podfeet.com/blog/pbs-index.

CCATP #535 – Bart Busschots on PBS 53 of X — Bootstrap Utilities (5/5/2018) by podfeet

We’re finally back to a new episode of Programming By Stealth after a few weeks chatting with different things like GDPR and DNS with Bart Busschots. In this installment, Bart starts explaining the Utilities available in Bootstrap. We’ll learn how easy it is to use the pre-built CSS styles in Bootstrap to color text, add borders, spacing, text alignment and fonts all with semantic phrases that actually make sense! In an odd bit of luck, Bootstrap had been updated and Bart’s code didn’t reflect the new version. In most shows, this would be a problem but the change allowed Bart to walk me through how to figure out what was wrong and how to access the Bootstrap documentation to fix it. The best way to learn something is to break it first, or at least Bart and I feel that way.

CCATP #531 – Bart Busschots on PBS 52 – Introducing Bootstrap 4 (3/31/2018) by podfeet

We’re finally back after spring break, and we’re going to be moving on from JavaScript while we learn about Bootstrap. Bootstrap is a set of open source libraries which provide pre-built foundations for creating responsive and good looking websites. It’s an easy episode with easy and fun homework I think you’ll enjoy.

CCATP #530 – Bart Busschots on PBS 51 Cellular Automata Wrap-up (3/3/2018) by podfeet

As our last episode of Programming By Stealth before our spring break, Bart wraps up our Cellular Automaton. He goes through his solution to the PBS 49 challenge first, and then he walks us through three examples of how a user could produce three different representations with our code. He demonstrates how to build a Conway Game of Life, the Maze Rule, and Brian’s Brain. It’s fun to see it all wrapped in a bow ending this long project. We’ll be back on March 31st with a whole new project.

CCATP #523 – Bart Busschots on PBS 50 – Building a Web App on Video (2/18/2018) by podfeet

This week Bart and I celebrate 50 episodes of Programming By Stealth. As Bart points out, we’ve been at this for two years now. I’m so happy he’s stuck with me on this and he says he’s got literally years of material yet to go. To commemorate this occasion, Bart got the crazy idea to build a web app live on video. We used a YouTube Live Hangout on Air while he shared his screen. He started with a blank canvas and when he was done we had a working web app. The video is probably a better experience but the audio is supplied for those who prefer it. We did try to narrate what was going on to help with the audio.

CCATP #522 – Bart Busschots on PBS 49B of X – Object Revision & Improving Our Cellular Automata (2/10/2018) by podfeet

As promised last week, Bart Busschots brings us the second half of Programming By Stealth 49. We start by going through a lot of revision on JavaScript objects. It’s really great to have all of this all in one place, and I got to ask a few questions that have been bugging me for a long time. I understood every bit of this and really enjoyed it, but I’m not going to lie, his little 6-part test after the revision baffled me a bit. But after we slog through that part, Bart gets us back on track improving our Cellular Automata. I never realized that we didn’t actually define whether our cells are dead or alive!

In this week’s episode of Programming By Stealth, Bart had intended to work on improving our Cellular Automata, but we ended up spending a lot more time on reviewing the challenges from last week that we stopped before getting to the new stuff. The good news is that we’re going to do the Cellular Automata improvements in only one week (it will be PBS 49B), and we have no homework for the week!

CCATP #517 – Bart Busschots on PBS 47 – ES6 Polymorphism (1/6/2018) by podfeet

In this installment of Programming By Stealth, Bart teaches us about inheritance (relationships between classes) and polymorphism. Now he said polymorphism is a concept that throws most first-level college students, but in an odd twist, I didn’t find it confusing at all! Plus, he lets us play with cows, ducks and turkeys in his example so it’s loads of fun.

We also have a great new study tool created by Dorothy, aka MacLurker. She created an index of terms so you can jump right to the blog post where Bart talked about the term. I’ve been using it and it’s grand! You might want to bookmark podfeet.com/blog/pbs-index.

CCATP #516 – Bart Busschots on PBS 46 – ES6 Spread Operator, Arrow Functions & Classes (12/21/2017) by podfeet

In this installment of Programming By Stealth, Bart adds one more thing to the list of changes to arrays, and that’s the spread operator. Then we’ll learn how to get rid of the “const self = this” kludge for callbacks using the arrow functions. After that, we learn the basics of classes, a concept introduced in ES6 which brings JavaScript into the world of other C-style languages.

Bart’s excellent written tutorial for this installment is available here: pbs.bartificer.net/…

Bart at the end asks a question – would you be interested in learning how to build command line apps using JavaScript? So far we’ve only be working on web apps, but command line apps will allow us to manipulate things in the file system, the network and even to the Internet itself without using a web browser. Let us know via email to me at allison@podfeet.com, or write up your thoughts in our Facebook group at podfeet.com/facebook or our Google Plus group at podfeet.com/googeplus or you can even tweet us at @podfeet and @bbusschots.

CCATP #514 – Bart Busschots on PBS 45 – ES6 Arrays & Strings (12/11/2017) by podfeet

In this week’s Programming By Stealth, Bart starts by actually giving me credit for leading him to rethink his strategy on the use of const and let. He was nudged along in the strategy by the most awesome Jill.

Then Bart goes on to reveal even more of the joy that is JavaScript ES6. He explains ES6 Arrays, how to loop through Arrays, and in a change that brings a tear to my eye, the simpler way you can now loop over Strings and how concatenation is a thing of the past when building strings. This is truly a joyful show!

CCATP #511 – Bart Busschots on PBS 44 – ES6 Arguments & Objects (11/26/2017) by podfeet

In this installment of Programming By Stealth, Bart Busschots teaches us new ways to deal with arguments and objects in JavaScript ES6. We learn how to set default argument values for functions in a way that is self-documenting. He explains how variadic (aka Rest) arguments allow you to shove all of the arguments of a function into an array. Then he walks us through how to use for … in loops to loop over objects. He reminds us of the difference between instance and static properties and explains how for … in loops work with both kinds of properties. I really enjoyed this episode and followed almost all of it on the first time through!

CCATP #509 – Bart Busschots on PBS 43 – Introducing JavaScript ES6 (11/12/2017) by podfeet

In this installment of Programming By Stealth, Bart spends most of the time talking through his solution to the previous challenge, where we added start and stop buttons to our Game of Life. In his solution, he actually modifies the prototype to accommodate the ability to add these buttons. He explains his process and his decisions along the way. I’m not going to lie, this one confused me quite a bit in the middle but we both hope it’s because we’ve been away from the hard-core JavaScript for quite a while.

Once we have that under our belts, he starts explaining some of the cool, new features in JavaScript ES6 where we abandon var and replace it with let and const. He explains the value of these new terms (and the problems they solve!)

In Programming By Stealth, installment 42 of X with Bart Busschots, it’s finally time to tie all the bits and pieces we’ve learned together and create our first web app. Armed with our HTML, CSS, jQuery and JavaScript knowledge, and our Cellular Automata Prototype, Bart walks us through how to bring the Game of Life…to Life! It’s a lot of fun and I understood a great deal of it (I’m not gonna lie, it wasn’t 100% this time.)

CCATP #505 – Bart Busschots on PBS 41 – Form Events (10/13/2017) by podfeet

In this episode of Programming By Stealth, Bart ties up the last of the loose ends related to web forms. He teaches us about form events, which are critical to making our web forms not only accessible to screen readers but to allow our users to tab around to the different fields and interact with them without using a mouse. We learn about the keypress event and learn what it means for 31 to be the space key.

CCATP #503 – Bart Busschots – PBS 40 of x – HTML5 Custom Validations with jQuery (9/30/2017) by podfeet

In a shocking turn of events, I actually followed all of Programming By Stealth this week! Bart walked us through his solution to last week’s HTML5 Forms Validation homework, and in so doing highlighted some especially clever things he did. I was pretty pleased with my own version of the homework, and in fact, Bart gave me a gold star for one thing I did. Bart also explains how he used CSS to make his form even more readable.

In the second half of the episode, he shows how to use jQuery to improve the forms even more. He demonstrates how certain requirements cannot be met with the built-in forms validation and how we can use jQuery instead. I loved this episode because it tied in our knowledge of jQuery back to HTML forms.

We finally reached 500 episodes of Chit Chat Across the Pond (episode 499 will be next week) so who better to have on the show than Bart Busschots who started it all?

In our first Programming By Stealth after our summer vacation, Bart decided to do a retrospective on what we’ve learned to date from HTML to CSS to JavaScript. I thought it was a great episode because it refreshed my memory on so much that we’ve done. He even put together a set of quiz questions for each section and shockinglyI didn’t do too badly at them!

CCATP #494 – PBS 37 of x – Bart Busschots JSDoc Demo (7/9/2017) by podfeet

I’ve been asking Bart a lot of questions in the back channel as I struggle to understand the documentation he has provided in our latest few sessions of homework assignments. He had an epiphany last week that he had never explained the documentation methods itself, which was certainly adding to my confusion.

He decided to take a step back and explain step by step using video. He created a video screencast of the entire process of creating documentation using JSDoc. Then during the audio recording you’ll hear in the podcast, he walked through it again while I asked him (lots of) questions. Hopefully it will be as eye opening to you as it was to me. He also demonstrates his favorite tools for the process.

CCATP #492 Bart Busschots – PBS 36 of x – More HTML Text Input | More Cellular Automata (6/25/2017) by podfeet

Chit Chat Across the Pond this week is another episode of Programming By Stealth with Bart Busschots. I’m very proud of the fact that I completed my homework, writing a program from scratch that passed all of the tests written by Bart. It took me 12 hours, and nearly 4 hours of Dorothy’s time helping me do it, but I got ‘er done. In this installment, 36 of x, we learn some more HTML, specifically about all the cool things the input tag can do, like creating invisible forms which is just weird but also very cool. The challenge this week is a flip on last week. This week Bart has written the next bit of code for us and we have to create the tests. It’s as challenging as all the rest but it’s just as fun.

CCATP #487 – Bart Busschots PBS 35 of x – HTML Text Input | Introducing ‘Life’ (5/19/2017) by podfeet

In this installment, Bart walks us through a little bit of how he wrote his Test Driven Development with QUnit for the Bartificer Link Toolkit. Bart even explains how it helped him find a couple of pretty major bugs in his own code, proving how important this is. Then we’ll move on to formatted sub-sets of text like numbers, email addresses and so on.

Finally, we make a start on what will be an on-going project. The idea is to combine our understanding of HTML, CSS, JavaScript, jQuery, and QUnit to implement a zero-player with a really cool computer science back-story.

In this installment of Programming By Stealth, Bart FINALLY lets us start learning Test Driven development, or TDD. He shows us how to use a free and open source tool called QUnit, made by the fine developers of jQuery, to analyze our test code. It’s something I’ve been itching to learn more about, ever since listener Jill tipped us off to the concept. It’s a really fun episode where everything kind of comes together.

CCATP #478 – Bart Busschots on PBS 31 of x – JS Static Functions | Checkboxes & Radio Buttons (3/1/2017) by podfeet

Bart and I may have broken a record on Chit Chat Across the Pond this week. We went through so much material in Programming By Stealth that this show runs 100 minutes! The funny thing is that I wasn’t ever bored, it was all really interesting. We started by going over last time’s JavaScript challenge where I made some mistakes but node.js saved me so I didn’t realize I’d entirely missed the point. I’m still getting the hang of that object thing. The we learned one final new concept related to JavaScript prototypes: static functions. The we finished that we went over to the html side and learned how to make forms, checkboxes and radio buttons. Not nearly as mentally challenging as JavaScript to be sure, especially since you can see the changes right on screen when you mess with them. Speaking of messing with them, Bart teaches us how to use jQuery to find out what our buttons and checkboxes say and to change them. He does this all with particular attention to using ARIA to ensure our html is accessible.

CCATP #476 Bart Busschots PBS 30 – Comparing JS Objects | Introducing WAI-ARIA (2/18/2017) by podfeet

Bart continues his current dual path of teaching. We learn how to compare JavaScript objects (spoiler, you can’t use == or === to do it). After that he teaches us how using WAI-ARIA as we develop our code will make it accessible to screen readers and other assistive devices. We don’t do any real coding in this section; instead he explains the foundation for what we’ll be doing in the future.
