Jan 04 The best way to learn about agentic coding is to install one and painfully prompt your way into your first project. Pain reducers: give it access to your full (backed-up) codebase and have it do a security scan. Or have it generate a few tests. Just get used to this tech. You’ll have to sooner or later. 13 0 7 832 306 .
Jan 04 Ever since I started coding with agents instead of typing every line, coding has been fun again. Particularly as a solopreneur, getting into deep flow is costly and often zaps energy from other tasks. Watching Claude Code do that work and diving into the final PR is bliss. šŸ§‘ā€šŸ³šŸ˜˜ 69 4 25 3.7k 280 .
Jan 03 I, too, would love to be a spontaneous foreign policy expert. Oddly, looking at my feeds, the people from back in my PoliSci university days, the ones I took foreign policy courses with, are not the ones tweeting ridiculous opinions. Isn’t that something. 17 0 1 2.7k 258 .

Dec 30 Of course, you can't rely on agentic code systems to write meaningful tests completely automatically. They've got much better at it, but you still need to read those tests to understand if the thing being tested is actually the thing you want to be tested. But beyond that, access to testing has become so easy that now feels like I would just automatically do it on every new project because it is so easy. Just this tiny little improvement has significantly increased the quality of the software that I produce. 9 0 1 1.4k 514 .
Dec 30 Before LLMs, I didn't test. I "had the full picture" (until a bug broke prod, of course.) Because of LLMs, I learned how to test. I had it write tests for me, then fixed them to make sense. You think LLMs write bad code? You should have seen mine before LLMs. Much better now. https://t.co/TRGzAk2mTj 64 6 17 4.8k 303 .

Dec 22 Bus factors don't just exist for bootstrappers. VOLA, an (objectively great prog) metal band, had their touring equipment ($200k+) go up in flames when a storage facility fire broke out. Insurance will pay $30k (lol), everything is gone. So far, fans have pledged $70k in their GoFundMe. Looks like they'll be able to recover from their fans alone. I've seen some fans donate thousands of dollars. True fans, you could call them, in Kevin Kelly's vernacular. Between merch sales, tickets, and these donations, they'll find their way back into profitability. The lesson for me as a founder is that disaster strikes whether we like it or not, but recovery depends on a strong presence with the people who care about your work. Engaged supporters MATTER. Also, you should really listen to VOLA.🤘 11 0 5 2k 798 .

Dec 20 Any field of expertise eventually reveals this truth: it is not stirring the sauce that is complicated and takes years of experience; it is knowing the right ingredients, pots, spoons, temperatures, and precise steps that make it hard.

Dec 19 This is the kind of stuff you can expect enterprise companies to already be tinkering with in their software engineering labs, trying to find a way away from the AI platforms hosted and controlled by somebody else, particularly in industries where regulation prevents most cloud software usage. This is the kind of work that will facilitate adoption of AI tooling into these companies, and it becomes critical for software companies to consider that not only do they have to do on-premise deployment of their software stack, they also have to be able to integrate into the on-premise deployments of their AI clusters. 3 0 2 838 619 .

Dec 12 A quick functionality summary: It finds people who most recently signed up for a trial and were scored as good prospects for my ICPs. It looks for similar companies, similar size, and location as those people, and figures out the right people to approach at those companies. It lets me review it in the email that was drafted to be sent to them. Pretty simple "hey, interested in this kind of stuff" email. That happens several times a day and guarantees a constant flow of interesting outreach targets that fit exactly who's already using the platform. And the more people from one kind of industry join, the more of their peers I find and reach out to. Buzz begets buzz. 4 0 1 1.3k 675 .
Dec 12 In a single day, I had my coding agent build an "existing customer lookalike and outreach tool" right into my Podscan admin panel. And I realized that the one thing AI struggles with is reliable data. Never the code. It can build complex things. But it can't build facts. 46 1 8 3k 273 .
Dec 11 Just had a call with a prospect, and they were all excited about automations, integrations, and how to set up their Podscan keyword alerts so they cover not just a brand but the broader market they operate in. I just spent half an hour on excited back-and-forth brainstorming and turned it into a highly well-structured article with great examples I instructed Claude to switch and "normalize" so that the customer's privacy can still be retained. Not only did I help a customer, but I got another way of talking about their problems and the solutions that they might need, which is now codified in an article that will soon start ranking. Low-effort, high-impact. And can be fully autoamted, too. 4 0 0 890 701 .
Dec 11 An extremely effective way to turn customer support conversations into high-impact blog posts (or KB articles) is to record customer calls, take the transcript, and have Claude/ChatGPT turn the conversation and its main problem(s) into helpful articles. Works REALLY well. 23 0 9 1.8k 273 .

Dec 09 Haha, this is wild. I mean, a fine is just a tax with a gun. But I wasn't aware of the discrepancy. It would be smart to grow the income tax portion of the equation. But I have a feeling that legislative efforts focus much more on the fine part. 9 0 6 3.9k 248 .

Dec 05 And just to clarify, I fully agree with Jack because that has been my own experience as well. Obviously I'm biased because I'm a solopreneur, but my throughput on the smaller tasks that would have taken me a day just to figure out is now a matter of minutes. All the potential contractor collaborators I could have paid won't be needed by me and likely many founders like myself.

Dec 05 Not because it's impossible to use informational advantage to make money—every entrepreneur does very much the same thing with their knowledge about the market and the businesses they create from it.

Dec 05 "Prediction markets surface truth to people" is the inverse of every single past example of how humans act in chance scenarios: fixing games to win, insider trading, and market manipulation.
