@SumitM_X I'd use `explain analyze` rather than guessing. More importantly you'd want an index on the status column.

Which SQL QUERY performs better? SELECT * FROM orders WHERE status = 'NEW' OR status = 'PENDING' OR status = 'PROCESSING'; vs SELECT * FROM orders WHERE status IN ('NEW', 'PENDING', 'PROCESSING');

@TheZvi Shopify doesn't have a QA team, doesn't mean their app isn't tested, it just means that their engineers and product teams are empowered to test and own their work.

"Safety is a dead org at xAI." "There is no safety team on the org chart." "There is zero safety whaotsever in the company - not in the image [model], not in the chatbot." "xAI engineers 'immediately push to prod[uction]. You survive by shutting up and doing what Elon wants.'

@elonmusk Always include `Today is #{Time.now}` in your system prompt

Room for improvement

@AdamRackis It can pretty much one shot feature flag cleanup... not that this is very hard, but it's good at finding all the references to the flag and removing the branch of code that's not longer needed. It's good for large refactors (ie. hundreds of places) that aren't just find/replace.

Where are my gainfully employed software engineers who use AI tools (vibe coders just sit this one out - here’s some crayons to play with) Am I using it wrong, or is it just faster to do smaller / non-obvious tasks by hand, vs writing a clear prompt and then verifying?

@darrinhenein @RepFitnessEquip Every time I use one of those rack builder tools they come to $8k and then I close it and think "maybe next year".

@leighchalliday @RepFitnessEquip Thanks! Yea the Ares 2 was what I was initially looking at, but it’s an add-on to a rack — so gets $$ quickly. That bench looks awesome though, might be time for an upgrade.

Planning an upgrade to the home gym—right now adjustable dumbbells + bench, bike, concept2 rowing machine. Looking to add something like the @RepFitnessEquip Arcadia — any reason not to/what would you recommend instead?

@dhh Curious how you think about testing when it comes to stimulus controllers. There is minimal system testing (amen) and I am not seeing JS testing. Is client-side behaviour validated in other ways and/or regression is caught through regular usage of the app?

The Fizzy test suite runs in UNDER FOUR SECONDS! Nearly 2,500 assertions. The magic is to lean hard on vanilla Rails fixtures and parallel test runners. Not only is this blazingly fast, but it's also achingly beautiful. github.com/basecamp/fizzy…

@dreamsofcode_io I open GitHub, I see the source

Personally, I believe any CTO should have a basic understanding of software licensing. Perhaps that’s a moronic thing to expect in 2025.

@wesbos Same genre, completely different artists :)

Any other sad angry bois got me beat?

@jasoncharnes I used fast-mcp and then mounted it within an existing Rails app

I'm out of the loop. Ruby folks: have any of you built an MCP? What gem did you use? I like that there's an "official" Ruby SDK, but is there a better one I should be using?

@yarotheslav @strzibnyj github.com/marcoroth/turb… is a great gem that provides a custom turbo stream redirect_to as well

@strzibnyj You can use custom turbo_stream actions to break out of a turbo_frame on demand. We've been successfully using this one-liner approach over multiple projects for years: #issuecomment-1934729149" target="_blank" rel="nofollow noopener">github.com/hotwired/turbo…

We need a conditional _top target in Turbo Success? Close modal and redirect Failure? Keep the modal and morph Seems almost as oversight not having it. How do you all solve this?

@victorelexpe @levelsio Also similar on maps, you search for locations within the bounding box of what is visible on the map rather than the whole earth's coordinates.

@levelsio Broadcasting only nearby players’ positions could lighten the server load, especially with 500+ users. It’s a common trick in MMOs to scale for big crowds

Okay it works again, still some spammers who made some floating plane crash above the runway but all good 😁👍 I'm parked next to the runway plane spotting everyone taking off 😊 Right now update rate is 1 second, if I go below I hit some limits and the server stops Tomorrow I'll try fix the performance issues so it gets smoother, and try adding multiplayer shooting so you can shoot each other down Would be sick with 500+ ppl 😬

@levelsio Rather than updating the position of the plane each tick, it would be cool to use old/new location to calculate trajectory + speed and smooth out the plane's flight path to avoid the jumps.

@MorriceGavin That's basically our exact stack at Wrapbook, right down to the creatine gummies. We've started to port our RN screens back to web views, moving away from the need to support GraphQL... good old Turbo. 100+ engineers working on the monolith.

If I was hired to start a new tech startup tomorrow, web + mobile app, this would be my stack: - Rails 8 monolith - PostgreSQL - AWS hosting - Creatine gummies - Cloudflare - Sidekiq - Jbuilder for JSON templates - ViewComponents + Slim in the FE - Dart SASS written in BEM - Vanilla JavaScript - ReactNative for iOS and Android I would veto any attempt to add any of the following to the stack: - Service objects - Tailwind - Any JS framework

@darrinhenein Congrats Darrin!

After 8.5 years, I'm excited to share that I’m taking on a new role as VP of UX at Shopify! The last few years have been filled with immense challenge as I stepped into a new part of the business, and continued to have additional teams added to my scope. It's been a period filled with tremendous growth and I'm forever grateful to everyone who supported me along the way, but especially: @jingleyfish @archieabrams @CynthiaSavard @nejatian and of course @tobi for taking a bet on me nearly a decade ago 🙏 And after all this time — I don't think I've ever been as excited about the future for commerce and the good, good work we're doing here on behalf of entrepreneurs around the world 🚀

@RogersKonnor It needs to know the row height (variable height is a WIP... complicated) and the IDs of the records to render... using that it can calculate the scroll distance and lazy load/render data from the server. Has some rough edges, but could at least serve as a proof of concept.

@RogersKonnor Here's a package I worked on to support virtualization in hotwire: github.com/wrapbook/hotwi… and a demo rails app that uses it: github.com/leighhalliday/…

@JoeyDeetz @Lightworker_SF Looking forward to the upcoming release!

@leighchalliday @Lightworker_SF Haha it’s true! Though I’m not a programmer or engineer. Thanks for listening!

Really digging these guys… and I think the singer works in tech! I always knew metalcore was the best programming music. youtu.be/eNA4hzPG8eU?si… @Lightworker_SF

@wesbos @gregisliving Check out these guys, Wes! youtu.be/7rFRET5BVbI?si…

@gregisliving Oo yeah. Check my metalcore playlist spotify.link/5j5cK3HmPHb

This song is such a banger. This video is such a fever dream.
