my second customer almost asked for a refund within hours, here's how i saved it in 30 minutes:
he subscribed, tried using the app, every single action failed. mailed me saying refund me or i'm charging back.
i panicked. first instinct was to just refund him.
instead i checked my vercel logs, found the real issue phones shoot 15-20MB photos now, my serverless function limit was 4.5MB.
every upload was dying before my code even ran, this was silently broken for every mobile user since launch.
fixed it in 30 minutes, added client-side image compression before upload, resized everything, converted to JPEG, went from 20MB to 500KB.
pushed the fix, told him to try again, worked perfectly.
the scary part? he was the first person angry enough to email me. everyone else just left forever.
your angriest customer is your best QA tester.

Today is a hard day. I shared this note with the @linear team today: We’ve made the difficult decision to increase our workforce. This is not a cost-cutting exercise or a reflection of anyone’s performance. We’re simply reimagining every role for the agentic AI era. We’re hiring. We’re sorry about that.

@catalinmpit @AlfredSimon It’s a general symptom of Romania’s economical situation. A grocery run is at a minimum 500 RON nowadays, whereas it was… 250 3-4 years ago? Has nothing to do with spending too much
English
@AlfredSimon Damn. So my feeling that we spend too much on groceries was valid.

I don’t usually share things like this, but I think it’s important to be honest.
I’ve been looking for a full-time role since September.
I’m a senior iOS engineer + product designer with 10+ years experience, and I’ve spent that time building and shipping real products (most recently: @ateiq_app, @naturalis_app, @getuppapp).
Despite interviews and ongoing work, I’m now about a month away from needing something stable for my family.
If you know a team that values someone who can both design and build, I’d really appreciate an introduction.
Thank you! ❤️

I'm giving away the Claude Code skills we use to manage $300k/mo in ad spend at ColdIQ.
4X ROAS on $1M+ spent.
Ivan, our head of growth, built them off 300+ hours running ad campaigns for our clients. They run Google, Meta, and LinkedIn ads from the terminal in plain English:
→ bulk edits across platforms
→ custom audiences from CRM lists
→ creative fatigue detection before CTR dips
→ bid adjustments at scale
→ performance audits across periods
Reply "ads" and I'll send the full repo. Must be following.

@rails @intercom @brian_scanlan this is so sad. writing code was the fun part of the job, especially with ruby.
i’m not saying i still hand write code. i just wish we could go back to 2008 when rails was king, code was craft and all of this was still *fun.*

In one year, @Intercom went all-in on Claude Code, doubling the throughput of their entire engineering and R&D org. Now 95%+ of daily code is AI-generated, with 1,000+ weekly users enabled across the whole company (including sales, marketing, and finance).
@brian_scanlan shares how they got there and where they’re going next on the next episode of On Rails with host @robbyrussell: podcast.rubyonrails.org/2462975/episod…

In 2023, we spent $3,934,099 on AWS + other hosting. In 2026, our hosting + support bill is down to ~$1m/year due to the cloud exit. Even including all the hardware buying, we will already have saved ~$4m by the end of this year. And going forward, it's ~$3m/yr in savings 🤑

Now that we're soon running out of 32-bit namespace for transfer IDs at @Wise, the engineers are annoyed with me choosing int over long when I wrote the first lines of code in 2010.
But why don't they appreciate the $17 of savings in storage cost over years!? 🤷

rails new --database postgres
rails generate authentication
kamal deploy
Voila, you own everything, only took 10 minutes.
Simon Høiberg@SimonHoiberg
"Just use Vercel." "Just use Supabase." "Just use Clerk." Cool. Now your auth, database, and deployment are owned by 3 different companies who can change pricing whenever they want. And the rest of your product is wrapping OpenAI. At some point you have to ask yourself: what do I actually own here?

@PranayReddy05 @seraleev That TLD has been available since at least 2019 :)

@seraleev It's so funny to see that there are new domain names coming out each and every year.
I don't know how I'll keep up with all this.

@MarkSchellhas @karpathy I agree, but you’d still have to manually handle the actual setup of payment gateways, signing up to infra, paying for the servers, et
English
@karpathy Or could also just use old school frameworks like Rails 😏 it’s CLI generates all the code you need for auth, payments, api, etc - ZERO tokens.
Add kamal for deployment, SSL, etc
Not every problem = LLM

When I built menugen ~1 year ago, I observed that the hardest part by far was not the code itself, it was the plethora of services you have to assemble like IKEA furniture to make it real, the DevOps: services, payments, auth, database, security, domain names, etc...
I am really looking forward to a day where I could simply tell my agent: "build menugen" (referencing the post) and it would just work. The whole thing up to the deployed web page. The agent would have to browse a number of services, read the docs, get all the api keys, make everything work, debug it in dev, and deploy to prod. This is the actually hard part, not the code itself. Or rather, the better way to think about it is that the entire DevOps lifecycle has to become code, in addition to the necessary sensors/actuators of the CLIs/APIs with agent-native ergonomics. And there should be no need to visit web pages, click buttons, or anything like that for the human.
It's easy to state, it's now just barely technically possible and expected to work maybe, but it definitely requires from-scratch re-design, work and thought. Very exciting direction!

When @karpathy built MenuGen (karpathy.bearblog.dev/vibe-coding-me…), he said: "Vibe coding menugen was exhilarating and fun escapade as a local demo, but a bit of a painful slog as a deployed, real app. Building a modern app is a bit like assembling IKEA future. There are all these services, docs, API keys, configurations, dev/prod deployments, team and security features, rate limits, pricing tiers." We've all run into this issue when building with agents: you have to scurry off to establish accounts, clicking things in the browser as though it's the antediluvian days of 2023, in order to unblock its superintelligent progress. So we decided to build Stripe Projects to help agents instantly provision services from the CLI. For example, simply run: $ stripe projects add posthog/analytics And it'll create a PostHog account, get an API key, and (as needed) set up billing. Projects is launching today as a developer preview. You can register for access (we'll make it available to everyone soon) at projects.dev. We're also rolling out support for many new providers over the coming weeks. (Get in touch if you'd like to make your service available.) projects.dev

Basecamp is now fully agent accessible with a brand-new and comprehensive CLI, wrapped by a great skill, and backed by a revamped and much expanded API. It's a fantastic way to give your agents access to everything in Basecamp and integrate it anywhere. basecamp.com/agents

$200/mo ChatGPT Pro + gpt-5.4 xhigh + Codex Mac App is the most asymmetric upside I've ever seen in a tool chain.
A ridiculous cheat code for founders.

Regardless of how much we're using AI; human intelligence, curiosity, and ingenuity won't be replaced. Case in point: Uber's real time map, Cloudflare's wall of lamps, and so many more examples
