SimGym is one of the coolest things we’re doing @shopify 🤖🛍️

@Drewch + @aaronglazer = dream team 😤

@jobergum The worst feature ever built

[Mikhail Parakhin @MParakhin]

We keep optimizing SimGym, both in terms of quality and inference costs. So, we just doubled the number of free runs merchants get and halved the price for when those run out. I feel the number of free runs is sufficient for most merchants :-)

[Alberto Castelo @acaste10]

If you are at #ICLR you can catch our talk about how we are building SimGym at @Shopify. Also come to our booth. https://t.co/A0yWLRRCwt

[Mikhail Parakhin @MParakhin]

Had a great conversation with @swyx on @latentspacepod about what we're building at @Shopify. SimGym, Tangent, our approach to PR review at 30% month-on-month merge growth and why larger models are cheaper in long run.
Swyx asks good questions!

@Cloudflare please buy @LaLiga and free Spain. #freespain

[Gergely Orosz @GergelyOrosz]

OK @eastdakota real talk: why doesn't Cloudflare buy La Liga. It's 8% of Cloudflare's market cap.

Then you can:

1. Stream La Liga, globally, as a massive subscription business, using your edge network, better than it's ever been streamed

2. Liberate Spain

Kidding not kidding

[Mikhail Parakhin @MParakhin]

Alright, not Monday, but the single-theme SimGym is out! Now you can just run simulations against your current version and get recommendations.

Hay una brecha con la IA.

Los que la usan de verdad. Alucinan, exploran y se preguntan qué es lo que se nos viene encima.

Los que no la usan. Y no saben lo que se nos viene encima.

[Kevin Clark @kevinclark]

Massive improvement to how Sidekick responds to complex prompts just rolled out. @colderoshay and @alxclrk dream team.

[Mikhail Parakhin @MParakhin]

Burning tokens so you don't have to! Just published more details on how SimGym works. Note the use of MIG - that's what enabled us to make it available for everyone.

[DHH @dhh]

@levelsio For some reason, Spain is really good at this. Same or next day results. Cheap too. Best I've found anywhere in the world. Denmark on the other hand is horrendous at this. Week long wait for results.

[Alberto Castelo @acaste10]

The speed at which we adopt good ideas is impressive. So many wins this week with auto-research

[tobi lutke @tobi]

OK, well. I ran /autoresearch on the the liquid codebase.
53% faster combined parse+render time, 61% fewer object allocations.

This is probably somewhat overfit, but there are absolutely amazing ideas in this.

[Mani Fazeli @mcfazeli]

Stop guessing. Test your store's next big idea with AI shoppers. SimGym is now available to all merchants on @Shopify.

70K NO es un BUEN SUELDO, lo que PASA es que ERES POBRE

70K es lo mínimo aceptable para vivir de manera normal sin lujos en una ciudad.

Si crees lo contrario, ENHORABUENA, te han lavado el cerebro. Eres pobre y no lo sabes, lo cual es muy triste.

Hasta que la gente no se de cuenta de la basura que cobran, esto no va a cambiar. Cada vez seremos más y más pobres.

Suben los precios, pero la gente sigue repitiendo que 3000€ netos al mes es un sueldazo, o 2000€ al mes. Van a una entrevista y piden esa basura, o aceptan otra basura aún más grande. La conversación tiene que empezar a cambiar ya

Su argumento es que casi nadie cobra eso, lo cual no tiene sentido. Que la mayoría de gente en España sea pobre no convierte 2000€ al mes en un buen sueldo.

@adrianmg I now consider myself a designer

[Alberto Castelo @acaste10]

@adrianmg I thought this was the point in which design became fun 😂(with LLMs)
