OK, here's a fun prompt -- paste this prompt into ChatGPT or your AI tool of choice. What does it know about you? How close is it?

My wife informs me that this is not, in fact, intended for use to help men pee without making a mess of the toilet.

Just watched the London fireworks on BBC -- they were completely wild! Hope they get a full replay for international viewing -- one of the best I've seen!

Safari tip of the day: grab a screenshot of a scrolling page from Developer Tools by right-clicking the HTML node and choosing "Capture Screenshot". Great for sharing a proposed website change without deploying somewhere!

Fun night last night! The legendary Branford Marsalis in Seattle, then the decorated gingerbread houses at the Sheraton. Guess which city this one is?!

4/ Want to keep a manual page open while you're working on a command? Right click and choose "Open man page" -- it'll open a separate tall terminal window to that page so you can keep it handy.

3/ Want to save your ssh and other CLI passwords? You can use the new Passwords app to autofill saved credentials into the command line too. Just right-click and choose AutoFill / Passwords...

I'm going to share a few macOS Terminal tips I learned recently that others might find helpful.
1/ Ever find yourself with a long command and you just want to change one thing? Don't just hold down the left arrow button, instead Option+Click and the cursor will move to that location.

For those of you following along with #AdventOfCode, you're probably groaning as you refresh your memory of regular expressions! Unless you're using #Swift, which has this lovely mini-DSL for expressing them. The two expressions below are equivalent, and Xcode can help you convert from the former.

Also leads to fun extensions like this, which makes today's Advent of Code exercise easy in Swift!

#Swift is full of helper methods that are really helpful for solving the kinds of problems you'll find in Advent of Code. Here are a few that might help you solve day 2 with a readable and efficient approach... #AdventOfCode

OK, off we go with #AdventOfCode! Day 1 was a gentle start, as is usually the case. I like that #Swift has:
distances.sort(by: >) // sorts an array in descending order
versus the approach of #Java:
Array.Sort(first, (a, b) => b.CompareTo(a));
Good chance to practice use of zip(a, b) too!
distances.sort(by: >) // sorts an array in descending order
versus the approach of #Java:
Array.Sort(first, (a, b) => b.CompareTo(a));
Good chance to practice use of zip(a, b) too!

2. The default terminal color schemes are fine, but I prefer something a bit more subtle. Download the Nord.terminal theme from github.com/nordtheme/te... and import it into Terminal. Click the "Default" button to set it as the default for all new windows.

I'm surprised how many people see screenshots of my terminal settings and want something similar. I have five simple steps for anyone who wants to upgrade their default macOS terminal settings. In just a couple of minutes, you can have a clean setup with a useful git prompt and pleasant colors.

Or you can do a `guard let`, which inverts the above. Here you can handle the error condition and bail out early, which reduces unnecessary nesting. It's really quite elegant!

You get used to this style very quickly in Swift, and it's concise for lots of different scenarios. For example, you can use try? to return a null rather than throw an exception, and then deal with it very naturally with an if let.

It's fascinating to me how much legacy code gets carried forward to modern systems. For example, want to use this 1987 AT&T terminal as the front end to your Linux box or Mac mini? The terminal software in every modern POSIX system knows how to interface with it, and thousands of others.
