The review below is from Caleb Fong, aka @GeekoSupremo on Twitter. Caleb is a long time NosillaCastaway who is also following along with Programming By Stealth. His review is pretty geeky (goes well with his Twitter handle) so I thought it might help to explain a couple of terms he uses.
He’ll use the term *nix which is a term that means any UNIX-like system. *nix can mean any kind of linux, or even macOS since it’s based on FreeBSD which is a descendent of UNIX.
He also talks about Vim. Vim is a text editor in *nix operating systems. It’s a descendent of the original Vi, and in fact, the name stands for Vi IMproved.

In my post about using regular expressions to find matches in a text file, I promised to tell you about the two applications I used to help me write my regex. By the way, Regex is what the cool kids call Regular Expressions.
Let’s state the problem to be solved first. If you have a text file where you want to change something that’s repeated throughout the file, it’s pretty easy to do a search/change all. We do it all the time in text editors. But what if you have a text file that is repeatedly generated and always has the same thing wrong with it? Maybe it’s a date in the wrong format. Or maybe an online system hasn’t been updated with your new company name. Or what if instead of changing the text, you just need to know what the text actually says? Let’s say it’s a date in a document and you want to write a script to change the name of the document to include the date? All of these examples are a great place to try out regex.
We’re entering chapter 3 of my quest to provide chapter markers in the podcast. The original request was from Joe LaGreca but since I’ve started talking about it on the show, people have been coming out of the woodwork saying, “Yes, please!”
I have been working my little fingers and brain to the bone on this and I’ve figured out a really geeky solution. But first, let’s walk through what doesn’t work.
To review, I record the show in Hindenburg Journalist. I stop recording when I end each topic anyway, so it’s super easy to hit ⌘-control-enter to add a chapter and then type in the subject. The problem is that Hindenburg isn’t embedding those chapters on export. The dev and I have gone back and forth a few times and they seem to be saying that the chapters should be maintained, but they’re definitely not in the file.
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.
Erica Peterson of Moms Can: CODE joins us this week to talk about her new startup designed to help mothers who code to connect and collaborate.
We talk about her life as a mother of a five-year-old, while coding, while teaching high school biology, creating a startup and running a non-profit. The non-profit is called Science Tots, which is focused on bringing STEAM activities to non-science-based events.
This week Bart Busschots joins us to talk about HTML Form Validation. We’ll get back to our Cellular Automata next week. Bart has also decided that we’re going to get our feet a little bit yet by using GitHub where we’ll be getting the challenges and solutions from now on. You can see Bart’s awesome tutorial at bartbusschots.ie/…
This week our guest is Kelly Guimont. Kelly is a contributing editor to the Mac Observer and also a volunteer at App Camp for Girls, a program that introduces iOS programming to girls in grades 7-9. We talk about how a 3rd grade teacher asking her to crawl under a desk to plug in an Apple ][e turned her into the computer nerd she is today. She explains why you need a duck to be a programmer and a hula hoop to teach girls to code.

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. And of course you can find Bart’s fabulous tutorial show notes at bartbusschots.ie/…
