When a requirement specifies the solution, the design is a tautology. Separating requirements from solutions is key to doing design.

@zilasino If it's a hardcoded concept that code will reference explicitly, enum. If code can break if a magical DB row gets deleted or isn't seeded, that's a red flag for me.

Do you use enum in Rails, or do you prefer a separate lookup table in the DB?

@zilasino For new work I use ActiveStorage. For existing projects that started with CarrierWave, I stick with that. CarrierWave has everything on the model while ActiveStorage adds some joins, so if a legacy app isn't careful you can accidentally end up with subtle N+1 if you migrate.

How do you handle image uploads in 2025? ActiveStorage, Shrine, or CarrierWave?

@phillyrb @kcdragon_ Curious what the % of attendance work at Power Home Remodeling? RailsConf left me with the impression that most rubyists currently in the area are work there.

We had a great time listening to @kcdragon_'s Intro to Hotwire Native last night. We're working on setting up some great speakers in 2026. We already have January setup (look for the announcement soon) and have slots for February and March open for anyone looking to give a talk.

@phillyrb @kcdragon_ Sorry to have missed it! Need to clear my calendar for these in-person Philly.RB meetups. Haven't been to one since the University City days. I could potentially talk about rehabbing rspec test suites for legacy applications if anyone would be interested in that.

@ThePrimeagen I refuse to believe anyone at any point of history did a significant amount of editing in ed. Only reason I've ever opened it was because Linux for Dummies had a chapter on it back in the day.

someone unironically using ed in 2025?

I wonder what percentage of the internet is going to be down today due to the CloudFlare issues. I would imagine no where near the scale as when AWS hickups, but still. It's unfortunate how we added points of failures to the biggest decentralized system in the world.

@rjs Are you talking about a world where what agents generate is deterministic? If I'm understanding you correctly, I have a hard time seeing prompt input replacing the role of declarative code as long as the result of any given prompt has some randomness to it.

While I truly love declarative code that expresses a domain model .... I have to admit a sneaking suspicion that the "code should communicate the design" adage is going to get revised. I suspect we're going to see more domain modeling happen one level up from the current level of code implementation. Basically, what we see in things like DDD and "Domain Modeling Made Functional" but as an input to coding agents. It's like extending the trend of high-level languages up another tick.

@samsutliff 2003 me couldn't imagine anything replacing AIM or video calls ever being good.

Almond milk is the Skype of milk. Imagine explaining that sentence to yourself in 2003

@samsutliff Everyone called them the el and the subway when I was in college.

Ok call me a Philly poser, but I've always heard the El and the BSL. But today I heard a real vintage Philadelphian calling the BSL "the sub" and I am well and truly obsessed. Is this a real thing or was it just this one dude?????

I'm nearly convinced inheritance in programming is actually an AntiPattern.

After 20 years, I finally found something I strongly dislike in ruby on a language level. If you define a setter like `foo=` if you do `foo = :bar`, the expression will always return :bar. It's impossible to get `foo=`'s return. I guess it's true that no one is perfect after all!

How am I just learning about `git switch -` today?? I've spent so much mental energy when hopping into another branch to check on something over the years.

@ThePrimeagen Why not both. :)

I find the new twitch mobile app very confusing. Every time I open it I can't tell what I'm doing or where I'm going Am I a boomer or is this bad design?

@thePipester CrowdStrike. Windows is an innocent bystander here

So, as I understand it, Microsoft updated Windows, then CrowdStrike updated their agent, then Microsoft updated Windows again and then world broke. Who takes the blame here?

I've been using vim key-binds for over 20 years and I still don't really know them. I move lines around with `dd (move) P` all the time. Somehow I managed to lowercase the entire line while I was doing that. Never did that before!

@cpm don't think i don't see that hoodie in the photo

I don't know what happened to my YouTube algo a few weeks ago that makes it now feed me 30% @ThePrimeagen react videos, but I'm here for it.

@JasonSwett @solnic29a There's 2 pieces here. 1) Should we use cmd/form objs? Maybe. Depends how complex CreateUser is. 2) Is PM more readable for success/fail processing? Maybe. I like non-recoverable failures (like DB failure) to be exceptions. If you only have 2 states left, PM is noisier.

@solnic29a Relative to a Rails controller I feel like there's too much noise and machinery. (To be fair I think your example and my example don't do the exact same thing.)

Ideally, code tells a high-level story about what's happening, and hides the machinery that gets in the way of the storytelling. It shows the essential and hides the incidental. I feel like this code does roughly the opposite.

@schwad_rb There was a published version of _why's guide?? How am I only learning about this now?

Lucas is two weeks old today. It’s also the day he first learned about Ruby.
