Bart continues his miniseries on shell scripting by teaching us conditionals in the shell. In order to explain why conditionals are a bit odd in shell scripting, Bart first walks us through how it was originally done and then shows us the evolution to a much better method. It's still weird, and many things are opposite of what you'd expect (like 4 is actually > 10), but he gets us there in the end. I was most excited to finally learn what `fi` means, which shows up in shell scripting and I'd seen before in AppleScript.

In this episode of Chit Chat Across the Pond Lite, Bart Busschots joins us to talk about weather apps. He’s a serious weather nerd by necessity, living in Ireland and being an avid bike rider. As he walks through the apps he’ll explain which ones fall down on privacy, which ones have good apps for everything from the watch to iOS to the Mac. He’ll even go through how he uses different widgets to help him decide how much rain gear to wear.

CCATP #792 – Bart Busschots on Rethinking Weather Apps for Privacy and Functionality

In this episode of Chit Chat Across the Pond Lite, Bart Busschots joins us to talk Dyson vacuums. I know that doesn't sound too technical but you'd be surprised how advanced the tech is in the new devices. I share a few of my Dyson stories too and we both talk about our love for everything Dyson. Hide your pocketbooks before listening because all Dyson products are super expensive!

CCATP #791 – Bart Busschots on Submarines, Lasers, and Vacuum Cleaners???

In our previous episode of Programming By Stealth, Bart Busschots taught us how to create lookup tables with jq from JSON data using the `from_entries` command. Just when we have that conquered, this time he teaches us how to do the exact opposite – disassemble lookup tables. I think this was a really fun lesson because taking data apart, reassembling it the way you want and then putting it back together again is a great way to really understand what we're doing with jq. I got much more comfortable as I started to recognize the patterns in what Bart was doing. We also get to play with a new data set, the Have I Been Pwned data gathered by Troy Hunt.

If you're a data nerd, and really who amongst us isn't, you'll love this episode too.

CCATP #790 — Bart Busschots on PBS 164 of X – jq: Working with Lookup Tables

In this episode of Programming By Stealth, Bart Busschots as usual works through his solution to the challenge from last time, and as usual I learn a lot more about how to use jq to solve problems. He takes a bit of a detour to explain a fun email we got from Jill of Kent in which she explained the vast number of headaches you'll run into when trying to alphabetize names no matter the language.

Then we buckle down and learn about how to make tradeoffs between speed and efficiency of resources, and how jq lookups can help us. Bart also helps us understand _when_ lookups can help us with querying JSON files.  

This episode is more of a lecture, which is fine because he's introducing a new concept and explaining some philosophy. You won't hear me breaking into the conversation very much but it's only because I'm not confused!  Don't worry, when we get into the final example you'll hear me get confused! Bart explains it about 3 or 4 times and when you hear why your co-host here was confused, it's kind of ironic.

CCATP #789 — Bart Busschots on PBS 163 of X – jq: Lookups & Records

Bart Busschots is back to teach us how to alter arrays and dictionaries in JSON files using jq. Bart went through his challenge solution on cleaning up the Nobel Prize database and I learned a lot from it. Maybe he’d already taught all of it to us before but I sure wouldn’t have been able to put the pieces together.

For the new content, we learned how to alter arrays. We mastered sorting and reversing, how to add and remove elements, how to deduplicate the values within, and how to flatten even nested arrays. From there we learned how to manipulate dictionaries by adding and removing keys.

It’s a very focused lesson that continues to show how powerful the jq language is. I think my favorite part though was when Bart made an existential philosophy observation when he said “Everything exists with the value of null.”
