My daughter is 3 months old.
She'll grow up calling out attacks to her PokΓ©mon like Misty, in real time.
Here's what I built with Opus 5.5:
- Took Pokemon Emerald Arena from @germanburgardt
- Whisper on-device (~250 ms)
- @typesafeai Jev picks the move (~250 ms)
(sound on)
i am trying to build a software company with only design engineers. ai is now the *best* technical talent on your team. that being said, i believe as an application startup, we can outsource architecture design to agencies like evil martians. i'm thinking of doing "refactoring" audits every quarter or so to reduce tech debt and maintain the codebase at a "vibecode-friendly" state.
caldotcom and calendly are both great products. however the sad truth is that you probably will reschedule events. not because the product did an awful job, but you are doing a favor to others. you do NOT have control over your time the moment you hand them your calendar.
i think the best form of craft comes with a good balance of being isolated and communicating with the real world. that being said, being in sf might not be the best choice if you are trying to build an outstanding interface and user experience. everyone is making the same thing βΒ muse, instinct, poke, ... not to mention all the workspace products with identical sidebars. imo notion stood out because it portrayed the founders' philosophy and this matured while they stayed in kyoto. some times blocking yourself away from the noise is a smart choice.
hot take: sidebars are only good for workspace products and are usually better suited to landscape orientation. if your app is designed for portrait view, i advise against using them - use drawers instead.
i don't understand how ppl have hard time finding a startup idea. you can just pick from these:
- sales: clay, monaco, lyra
- marketing: semrush, profound, mainframe
- video: higgsfield, runway, heygen
- design: figma, paper, pen
- dev: codex, devin, greptile, depot
- communication: slack, notion, linear
- tools: dia, aside, char, anarlog
- data: scale, intelligence, arena
what else am i missing?
i think some ppl are way too scared to make decisions of their own
Palmer Luckey on how he hires at Anduril: he looks for people who worked on projects they cared about, not ones given to them, because that's what drives you to learn the most.
"Whether it's college or the state-mandated younger educational system, don't look to them to tell you, 'Here's what electronics projects you should be working on. Here's what you should be doing to learn how to do these things.'"
"One, they're often years or even decades behind what industry and hobbyists are actually doing, so you're gonna be learning how to do things that are ancient."
"Two, when you're working on something that you're only doing for yourself, you're gonna make way better decisions in what you teach yourself, in how you do things."
"When I hire people at Anduril, I look for people who have done projects that were outside of what their work paid them to do or what their school made them do. Because that means they're the type of person who is willing to work on things with their own money and their own time, because they wanna bring something into this world that wouldn't have existed otherwise."

there is now disposable software and premium software. scraping resources from websites was smth that was outsourced on upwork 3 years ago, now it's all done by codex. if you are not building premium software, it will die eventually.

Replying to @bnj
Itβs also just isolating - even earliest employees canβt truly empathize or understand the pressures and responsibility.
introducing bowser
for the love of god please stop this nonsense. i keep seeing shit products on my timeline every time i refresh.
i always think about this. now that i use @aquavoice all the time, i try to look at my dictation streaks too. keep yapping and typing!
a lot of webkit browsers dropping lately but i fcking hate webkit so no thank you for me. also the reason why their bundle size is so small is they lack features duh.

Is this how higher dimensional beings see us - every moment at once?
Starting to understand what Vonnegut meant by humans being βgreat millipedesβ - clearly it applies to our four legged friends too!
