Feel like I learned this the hard way and I've been wrong. My thought was that these new entrants with obviously superior DX would fill the gap that AWS et al had neglected forever. Turns out they were focused on the right things: security, reliability. Agents filled the DX gap.
F’it, just put your entire stack on the hyperscalers. Don’t use Superbase, Resend, Heroku Vercel, Railway, Twilio, Loveable, WordPress, Mailchimp, Just build it all on AWS, Azure, GCP, and Cloudflare.

@Gucci_Ochocinco what’s the verdict on the Nathan Fielder flick? I loved his comedy but seems like people are making this a big deal.

@ads you halted our account before we spent a dime. Legitimate business, your support channels are giving us the cold shoulder. Making a big mistake here?

Jev is really cool. The speed and cost are so refreshing, there's just so much space to build. The strength/intelligence of the model is also incredible. That said, the form of the inputs and outputs is begging for distillation in the same way that labs stopped vending logits.

I suspect we'll see some sort of "local jev" pop up very soon distilled (incredibly cheaply) via their API. Fine-tunes and teacher/student drop the costs of this architecture for real applications by another order of magnitude.

AI-generated-as-close-to-clone-without-being-illegal clones are going to be the bane of software. Intellectual property is dead.

Being inspired by design and/or features is different from the core claim of copying code, which appears to be false. But we will report back if there’s any code at all that was taken, it’s hard for me to get something detailed in 5 minutes, but x moves quick and jumps to a lot of conclusions so making my thoughts known quickly is important

Anyone who has actually done this knows why this story is bullshit.
Worked with a guy who *literally* dumpster dove to grab old 486s & Pentiums and built a Beowulf cluster in his cube. He extracted a single company's data, flattened it, and the queries that used to take *hours* happened in seconds. He showed the company how we had that ability practically for free. The suits *loved* it and decided instead of practically free hardware, they'd just buy super expensive IBM Blade servers. He quit & because a local brewer instead.

A miraculous vision of the future to have massive solar arrays in space powering sand-turned-intelligence pushing the limits of physics, mathematics, and human ingenuity to beam back "You're absolutely right!" hundreds of times a second to earth.

Codex app is surprisingly buggy. Threads that I can never archive. Prompts that never dismiss. Is no one using it?

@peer_rich when are you guys going to make an open source slack?

Amazon Echo selling me "premium" white noise when I'm trying to go to sleep is peak dystopia.

Publicly celebrating amazing interns is great engineering culture. First it sets the tone that great work is appreciated by senior leadership, regardless of title. Second it lights a fire under the asses of senior ICs “an intern did this! what are you doing?” without saying so.

My strongest advice for new founders is to try not to make a profit in California. The paperwork will end you.

I live and my company is headquartered in Washington. It’s that bad.

This is a great move from Vercel and a shot across the bow at Railway. Unfortunately memory ends up being the bottleneck.
Vercel pricing update: CPU billing is now based on active usage, not function duration. This means you no longer pay for time spent waiting on external services such as databases, APIs, or LLMs.

Why is @CharlesSchwab constantly trying to upsell their "voice ID" service so I can basically hand over my entire portfolio to any kid with a voice cloner? "Would you like to use ROT13 encryption as well?"

I earned $44 in a class action lawsuit against clif bars that alleges their label of “healthy” was misleading given the sugar content. So glad Erin Brockovich’s legacy lives on through these heroes.

“I was trying to solve this NP complete problem and it was going to take months! I dropped it into O3 and it completed in seconds and even explained its solution. Amazing!”

Writing a go or rust port of the typescript compiler or other well-defined program seems like exactly the sort of challenge an AI agent should be able to get good at. Curious why we haven’t seen success there yet?

This is true of almost any domain that matters.
This is pretty interesting...

I don't think the tariffs are a good idea but find a lot of the arguments against them to be unsatisfying and short-term focused. Makes things like housing affordability seem increasingly intractable.

"Remarkably, the Gmail team has shipped a product that perfectly captures the experience of managing an underperforming employee." 🤣 too true
I wrote an essay about Gmail’s useless email-writing AI assistant: “AI Horseless Carriages”. link and TLDR in thread
