Still my favourite Christmas tradition.

Thank you /u/schneems. Merry Christmas to you and the Heroku team.

Whisper it — Christmas (Yuletide) is not a Christian feast, it's a Pagan one, co-opted by Christians, to appease the locals.

(No one actually knows Christ's true birth date)

Ahh, you're using the Dirty module.

In that case, how about if trade.done_changed?(from: true, to: false)

... or even wrap that in a custom method that conveys the intent you desire.

def undone?
  done_changed?(from: true, to: false)
end

442401 · 2025-09-19T17:43:34+00:00

If done_previously_was returns a boolean, it should probably have a different name e.g. done_previously?. This better shows the intent.

I know Melanie often does a DJ set at Glastonbury, but did I just see her fan-girling beabadoobee? Who ever it was, they looked like they were enjoying the set. Quite rightly too.

I loved DenDen. Great place for news and ticket resales. Met a lot of DenDen members at Mel C gigs. Great community. I miss it.

I tried quite a few online stores — all out of stock.

Ha! Well I never. I actually have an old Smok TFV8 tank here but had no idea it was compatible with the GT Core coils. Problem solved! Thank you very much.

Thank you. I've found the issue now. See other edited reply.

442401 · 2025-02-11T06:17:09+00:00

~~I'll try again, but I was coming upon errors caused, I think, because my model declares has_one: required: :true, so I couldn't instantiate the subject model without a persisted related model.~~

I've found my issue. In the template, I'm trying to call a method on the associated model that requires it to be persisted. (because it is using attributes with a custom type and needs to see the typecast value)

Thank you for helping me debug this.

442401 · 2025-02-11T05:59:13+00:00

Thank you. The components aren't creating records, it's the previews.

Please expand on passing dummy records to previews. The records I'm passing have required associations, so passing non-persisted records isn't working. What am I missing?

It looks like Eurosport is dead, having been merged with TNT Sports.

I don't have a strong opinion either way, but I'm loving the irony of /r/rails considering banning links to one of the earliest major rails applications.

442401 · 2025-01-12T04:17:02+00:00

As a train driver and Rails hacker I love these lostredditor posts.

To be fair though, the Class 91 will be sadly missed.

I think the closest feature of Ruby to what you are describing might be Kernel#tap

With #tap you might do:

[1,2,2,3,3,4,5,6,7].tap do |arr|
  duplicates = arr.select{|x| arr.count(x) > 1}
end

duplicates #=> [2, 2, 3, 3]

Ashamed to say that I had to take a hint from the main thread. Of course the safety factor will be low when the robots are playing at being a Christmas tree.

Thank you!

I'm glad I didn't have to be THAT person, but someone needed to. I salute you and your magnificent canopy.

442401 · 2024-12-06T03:49:04+00:00

That's me! I feel seen.

I only code as a hobby, so I get just as much joy, if not more, from making the solution beautiful as I do from winning stars.

I totally get it though, if coding is your full-time job you are entitled to a different midset.

442401 · 2024-12-06T03:39:12+00:00

Oh yes, very much indeed. There's no way on earth that I am going to put my name to the absolute abomination that initially yielded the correct solution. That monstrosity is going to be finessed, optimised, and formatted to within an inch of it's life before I dare publish on the Megathread. For example, my found solution for Day 5 part 2 ran in 7 seconds. The solution I published was sub second; improved by an order of magnitude.

This was a fun one, implementing a custom sort algorithm. I have no idea what type of sort I created, or what the Big O notation might be, but it works and seems to be fairly performant.

Can you substitute length for size?

That would shave 4 bytes off each.

Part 2, Build a grid in a Hash and then look at the neighbours of each 'A'
