It’s been a long time since we did a Taming the Terminal episode but we’re back with episode 36 of n, screen and cron. You’ll hear me say this is episode 35, but with all these numbers flying around we got mixed up!
In any case, in this installment Bart teaches us two unrelated but really cool things you can do with the Terminal in macOS or Linux. The first is cron, a tool that lets you schedule scripts to run at specific times and days. The second is screen, which is a utility that allows you to create a virtual terminal inside your regular terminal. If that sounds head explody (as Bart likes to say), it kind of is, but of course he breaks it down and shows how really clever and useful it is.
Hi, this is Allison Sheridan and you’re listening to Chit Chat Across the Pond episode #463 for November 10th, 2016. This week’s recording is very different from anything I’ve done before. This story took place on September 16, 1945. On that date a horrific typhoon hit the island of Okinawa, Japan during World War II. My father, Ensign John Paul Moorhead, was serving as Chief Engineer aboard the LST 965 and was in that typhoon. He wrote a letter to his parents and my mother describing the harrowing experience of living through that typhoon.
I thought about reading my father’s letter aloud to you, but it didn’t sound right in my voice. I asked my dear friend and noted voiceover artist Ron David to read the letter to you instead. You may recognize Ron’s voice from Raise The Titanic on National Geographic and Wings on the Discovery Channel.
Before we hear the letter, I’d like to give you a little background. The ship on which my father served was an LST, which stands for Landing Ship, Tank. LSTs were amphibious ships designed to bring cargo and troops to unimproved shorelines.
I remember my father explaining to me that the LSTs were never expected to last long enough to come back home, because they were designed and assembled in such a hurry that they weren’t likely to survive for very long. I read online that the contracts were let to build the ships before a single test ship had ever been completed. This is not the kind of ship you’d choose to be in, in a typhoon.
The typhoon you’re about to hear my father describe reached winds of 150 miles per hour, beached 122 ships and small boats, sank five others and killed or injured hundreds of American service personnel. Since this week is Veteran’s Day in the United States and Remembrance Day in Canada, I thought it would be an appropriate day to bring you this very special Chit Chat Across the Pond.
If I don’t write now I’ll miss the feeling of this experience. It seems a million years ago that I wrote home. I will start with our trip down from near Kobe to Nagasaki, Kyushu. We were about halfway there when storm signs started showing up and we reversed course to run before a typhoon.
This week, Steve and I share hosting Chit Chat Across the Pond with retired electrical engineer, ham radio nerd, and remote control flier, Brian Johnson. Brian explains how he has taken his love of electronics and works to spread his enthusiasm to kids through volunteering at local schools.
The pinnacle of his experiences was when he got to help the kids at St. Bernard High School talk live using ham radio to astronauts aboard the Endeavor Space Shuttle. Lately he’s been teaching kids to build tiny ham radios and shoot compressed air and water bottle rockets and even learn the math behind why they work.
Apologies for getting the episode number wrong in the audio – I said it was #460 when it’s actually #461.
We’re joined by Shelly Brisbin, author of the book iOS Access for All and host of The Parallel Podcast. As she’s written more than a dozen tech books, I asked her to come on the show to explain how she creates her books, what tools she uses, and how she migrated from using an agent and a big publishing house to doing self publishing. It’s a really fun episode because while you’d think creating a book is all about writing, Shelly gets into how she uses TextWrangler and writes her own Cascading Style Sheets to create her books.
In this installment of Programming By Stealth, we’re working towards our first truly practical assignment in the series – a function that finds all links on a page, and if, and only if, they lead to an external page, alters them to open in a new tab, and appends an icon indicating that fact. Bart’s amazing full on tutorial is over at bartbusschots.ie/…. I also mention a fun little jQuery Easter egg, which you can find at citymapper.com. Just follow the link and open the console on your favorite browser and you’ll find a text based adventure game!
Allister Jenks joins us to talk about how he uses programming as a hobby and as a tool for solving problems.
In his always delightful way, he talks about early experiences programming and how they sparked such joy in him. We’re talking a TRS-80 clone here and a programmable calculator! He tells the story of how just last week he and I were talking about the relative weights of the iMac models vs. their screen dimensions and how he solved the ratio equations using Swift.
