Moved house. After three brutal days of boxes it’s a new (birthday) walk to work along the seafront. Brighton is an excellent (albeit windy) city, I encourage all my friends to move here.

The “mediative preparation” (of lanyards and hole punching) has begun.

See you on the 19th.

I promise I'll stop now. But I dug even further.

Think this is my favourite solution even though it's not the fastest.

odd_as, even_as = a.partition(&:odd?) odd_bs, even_bs = b.partition(&:odd?) odd_as.product(even_bs) | odd_bs.product(even_as)

A more error protected and false-y returning version with some Active Support help to keep it nice and terse.
require "active_support"; def odd_sum(a, b) = (a.select(&:odd?).product(b.select(&:even?)) + b.select(&:odd?).product(a.select(&:even?))).uniq.presence end

Solution to @cassidoo.co's latest programming challenge in Ruby... not quite there as a one liner, although the logic is sound.
(a.select(&:odd?).product(b.select(&:even?)) + b.select(&:odd?).product(a.select(&:even?)))

On a walk today, my son was saying "do you know what would be cool? If you had a blue tardis t-shirt where it looked like you were wearing it".

Later that afternoon...

Designed a load of fun t-shirts this weekend. Think these are my favourites. If you wear a t-shirt with it written on... you're a 10x engineer. Couple of nice colour schemes in there too.

Mornings like this in Brighton are a delight. It's the sign that it's coming up to brightonruby.com season.

Enjoyable little coding challenge from @cassidoo.co this week.
Solved in Ruby (using Rails's Active Support for time munging)
The problem: buttondown.com/cassidoo/ar...
def find_longest_time_gap(times) = times.map { Time.zone.strptime(_1, '%H:%M') }.sort.each_cons(2).map { (_2 - _1).to_i }.max / 60

Severed Ruby one-liner
puts (1..10).map { |r| (1..22).map { |c| (0..9).to_a.sample }.join(" ") }.join("\n\n")

Hey Zoom, is "what's new" just another button with AI sparkles next to it that I'll never click? If so, i'll pass.

And also getting something new ready too.
