<p>Well said.. yes, it’s more about validating hypotheses about what you’re trying to build.<p>My own hypothesis is that we could create a rough representation of your end user and create an agent loop around that to try to validate. It won’t work for all stages of product development where you need humans to give you feedback but likely useful in the beginning stages</p>

<p>Hi HN, this is my first Show HN submission.<p>I've been thinking about how product development will change with AI. The earliest stages of product development have so much ambiguity. Because code was costly and expensive, we spent a lot of time writing specs and doing user research.<p>I thought I'd try an experiment after (a) seeing advancements around evaluation systems especially for UX (b) realizing that AI can create a reasonably good enrichment of a persona/end-user (c) seeing karpathy's autoresearch project.<p>Autocrit is a pi extension. Start the pi harness and run the autocrit skill. It will ask you for a high-level app idea, and a definition of the target user. Autocrit will create a persona definition, has that persona create evaluation tasks, and then starts a loop where a coding agent builds a prototype, and a persona agent will try to use it in a real browser. They will judge it based on the tasks, giving scores and verbatim feedback. The coding agent creates a plan to fix things, keeps improvements, reverts bad ideas, etc. The loop runs overnight.<p>The goal is to get a better understanding of where to take the product at an early stage e.g. paper prototypes, before actually starting to build the product. The evaluation loop of prototyping and getting feedback is automated here, but humans provide the definition of the persona, app idea / product goals, and hypotheses that need validation.</p>

<p>Fork is awesome. I've been using Windows for the past year for a project and missed GitUp on Mac.<p>After trying a few clients (Tower, SourceTree, Kraken, and a few others) I stayed with Fork - very fast, performant, and intuitive. Right now I have about 15 repo tabs open in Fork with a large number of branches in each. The tree view is excellent (I actually liked the older one-line-per-entry version).<p>Fork recently added the ability to compare branches - literally click two times to get a diff within half a second.<p>I really can't believe this app is free. Well done to the makers of this excellent app!</p>

<p>I worked with Typescript for 2 years, then worked with Flow for 2 years and now I'm back on Typescript working for a big company.<p>I agree that Flow had better capabilities around soundness. But the tooling around Typescript really made me jealous, specifically in VSCode.<p>Near the end of working with Flow, Typescript was getting some cool capabilities like refactoring JSX for React apps.<p>Nowadays I can easily say that Typescript is a far better experience than Flow. There are updates every two months, adding some neat features that you might find in other languages.<p>Then you add in the power of surrounding tools and <i>their</i> ecosystems like TSLint and it really feels like a next-level coding experience where the tools start writing the mundane code for you, driven the core TS static analysis.</p>

<p>Yeah my laptop of choice is 15" MB Pro mid-2015. Picked up 2 of them over the last couple of years from Apple's refurbished store and I think with OS X it really is still one of the best laptops out there. A little tip - you can use <a href="https://refurb-tracker.com/" rel="nofollow">https://refurb-tracker.com/</a> to get alerts when they get in stock.<p>TBH it's the MB Pro + OS X combo that works so well. MB Pro + Windows is definitely sub-par... lot of other great laptops for that. I've never tried Linux on a MB Pro.</p>

<p>Pretty sure they're being sarcastic. But I'm guessing the commenter hasn't used Google Cloud anyway - Python 3 was supported on Flex enviroments for a long time. The news here is that they're supporting it on Standard environments, and there seems to be good technical reasons for taking so long.</p>

<p>Okay I know nothing about trading halts but reading this: <a href="https://en.wikipedia.org/wiki/Trading_halt" rel="nofollow">https://en.wikipedia.org/wiki/Trading_halt</a> it seems that Tesla is supposed to tell the exchange to halt trading 10 minutes prior to releasing news. Did Tesla initiate the trading halt here (late) or did the exchange?</p>

<p>This is actually what I'm afraid of - specifically vendor lock-in and being stuck with a stack that has high operating cost. From some of the comments I've seen, Firebase has high operating costs. But I'm still planning on testing this out myself with a small project soon.</p>

<p>Have you migrated anything off of Firebase? Or still kept the “base” projects and upgraded around it? I’m interested specifically in how expensive Firebase is for popular products</p>
