NC #655 Follow Up on Chapters, Reader View and Adding Workouts, Show Hidden Files, Mind Map iOS 11 Settings, Security Bits

I’m still working on how to get chapters in the podcast (this show might have them!) Follow up tips from Mike Price and Kaylee Dayo on Reader View. How Sandy and Allister saved Thanksgiving with their tip on saving a workout from last week. Bart brings us a Tiny Tip on a trivially easy way to show and hide hidden files in macOS Sierra and High Sierra. I mind mapped all of the settings in iOS 11, and it was utter madness. In Security Bits Bart and I talk about how Face ID isn’t broken, we learn about USB bugs in the Linux Kernel and how there’s a vulnerability in Intel chips you might need to know about.

Tiny Tip – Show Hidden Files

HiddenThis week’s Tiny Tip is from Bart Busschots. The problem he is solving is how to easily show hidden files in the Finder. There are various tools to do this, including using the defaults write command in the Terminal:

defaults write com.apple.finder AppleShowAllFiles YES

After which you have to relaunch the Finder. It’s not hard to do but you always have to look it up, and after you’re done looking for the hidden file in question you have to flip the switch to NO, and relaunch Finder again.

The Tiny Tip Bart discovered has been available since Sierra, but I sure never heard about it. It’s a beautiful thing.

With the Finder in focus, simply hold down command-shift-. And instantly all windows will show all hidden files! Hit the same keystroke again and they disappear.

I LOVE this tip. The keystroke is even easy to remember because . is often at the front of all hidden files, so command-shift-. Is entirely memorable.

Security Bits – 26 November 2017 – FaceID Isn’t Broken, USB Bugs in Linux Kernel, Vulnerability in Intel Chips

Security Medium 1 — No, FaceID isn’t Broken, but it Does Have Limits

A snazzy demo to the press had headlines all over the press screaming about how FaceID had been broken. But as is so often the case with stories like this, the devil is very much in the detail.

What the hackers really found was that it’s bloody difficult to trick FaceID — it takes a lot of time and effort, and even after you put all that investment in, your spoof only works in very carefully controlled circumstances.

CCATP #511 – Bart Busschots on PBS 44 – ES6 Arguments & Objects

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!

Detailed tutorial for the podcast is available at bartbusschots.ie/…
