@tomfgoodwin Or use a turn-signal while driving.

Huge fan of almost everything about Miami. But it does seem to be a city almost entirely lived in by people best defined as “I’d not return the shopping cart “ types Society vs individualism experiment

@TheMiamiApe Yes

Thinking about putting together a small monthly tech dinner in Miami. Nothing formal, just a table somewhere new each month. Anyone into that?

Is github.com the Github for AI Skills? It feels like there should be a simpler place to share, test, version, and keep skill up-to-date.

@burhansebin Where/what was the event Burhan?

Regular Wednesday night in Miami

@akothari Coconut Grove is a wonderful place for a Notion office.

First time in Miami!

@naval @naval, you mentioned on the podcast you have multiple agents checking each other's work, @cwsaylor built a CLI to reduce the copy & paste burden npmjs.com/package/tagteam

Is Traditional Software Engineering Dead? “Does this mean that traditional software engineering is dead? Absolutely not. Software engineers—even the ones who are not necessarily tuning or training AI models—these are now among the most leveraged people on earth. Sure, the guys who are training and tuning models are even more leveraged because they’re building the tool set that software engineers are using. But software engineers still have two massive advantages on you. First, they think in code, so they actually know what’s going on underneath. And all abstractions are leaky. So when you have a computer programming for you—when you have Claude Code or equivalent programming for you—it’s going to make mistakes. It’s going to have bugs. It’s going to have suboptimal architecture. So it’s not going to be quite right. And someone who understands what’s going on underneath will be able to plug the leaks as they occur. So if you want to build a well-architected application, if you want to be able to even specify a well-architected application, if you want to be able to make it run at high performance, if you want it to do its best, if you want to catch the bugs early, then you’re going to want to have a software engineering background. The traditional software engineer is going to be able to use these tools much better. And there are still many kinds of problems in software engineering that are out of scope for these AI programs today. The easiest way to think about those is problems that are outside of their data distribution. For example, if they need to do a binary sort or reverse a linked list, they’ve seen countless examples of that, so they’re extremely good at it. But when you start getting out of their domain—where you have to write very high-performance code, when you’re running on architectures that are novel or brand new, when you’re actually creating new things or solving new problems, then you still need to get in there and hand code it. At least until either there are so many of those examples that new models can be trained on them, or until these models can sufficiently reason at even higher levels of abstraction and crack it on their own… And remember: there is no demand for average. The average app—nobody wants it, at least as long as it’s not filling some niche that is filled by a superior app. The app that is better will win essentially a hundred percent of the market. Maybe there’s some small percentage that will bleed off to the second-best app because it does some little niche feature better than the main app, or it’s cheaper, or something of the sort. But generally speaking, people only want the best of anything. So the bad news is there’s no point in being number two or number three—like in the famous Glengarry Glen Ross scene where Alec Baldwin says, “First place gets a Cadillac Eldorado, second place gets a set of steak knives, and third place you’re fired.” That’s absolutely true in these winner-take-all markets. That’s the bad news: You have to be the best at something if you want to win. However, the set of things you can be best at is infinite. You can always find some niche that is perfect for you, and you can be the best at that thing. This goes back to an old tweet of mine where I said, “Become the best in the world at what you do. Keep redefining what you do until this is true.” And I think that still applies in this age of AI.”

@preston_holland @realChaseMartin ah, I missed the invite!

Perfect night in Miami at Fountainbleau Miami!

@dvassallo Excited for the new season, I don’t love the whining sound. Need and AI algo to rev match and overlay v10 sound effects 😃

Fascinating watching the battery level (right vertical bar on steering) and the regen level (top horizontal bar above gear number) in the new F1 cars as they go around a lap. Will be interesting to see how they use this to attack and defend.

More than 100 health systems now have enterprise access to Doximity's AI offerings, which includes DoxGPT and its scribe product, and those contracts will expand access to approximately 180,000 clinicians. In January, DoxGPT active prescribers queried the tool on average four times a week. "In our first full quarter since acquiring PathwayAI in August, we've already become one of the most used AI tools by physicians" fiercehealthcare.com/ai-and-machine…

UpToDate has long been a great clinical resource. I’ve been using DoxGPT regularly for clinical documentation, patient communication, and workflow efficiency, which has been incredibly helpful. It’s exciting to see continued innovation in AI tools for physicians across the industry

@Docslounge_ @BrandonLuuMD @UpToDate @doximity Glad you'd enjoyed DoxGPT, let us know how we can continue to improve it 🙏🏽

@BrandonLuuMD @UpToDate nice tool but they still cite their own expert-opinion articles as well as straight data. the AI feature costs a fortune. I use @doximity GPT (free) - all references, no expert opinion. glad to see more players in the market though.

UpToDate’s new AI is a genuine game changer. Every output is clearly linked to the underlying primary articles. It’s also remarkably strong at generating accurate differentials. Easily the most reliable clinical AI tool I’ve used so far.

@DrMiamiDerm @BrandonLuuMD @UpToDate Glad you'd enjoyed DoxGPT, let us know how we can continue to improve it 🙏🏽

@bryan_johnson What are you thoughts on IM8?

I’d cancel your AG1 subscription. They just completed a clinical trial and the results show no clinical benefit.  This has been obvious for years.  AG1 has no real product substance and is fundamentally an influencer heist.   Two simple alternatives (75% and 56% less $), outperform AG1 in randomized clinical trials. Two simple mono-ingredient alternatives that outperform AG1: 1. Chicory inulin 12 g daily ($20/mo) 2. Resistant starch 30 g daily for 12 weeks ($35/mo) AG1 is not worth $79/mo. AG1 study results (4-weeks, N=30): + No significant changes in blood biomarkers compared to placebo (CBC, CMP, lipids). + No statistically significant improvement in digestive quality-of-life scores (p = 0.058). + No significant metabolic or inflammatory biomarker benefits of any kind within the scope of what was measured in the trial. + Only small shifts in microbiome taxa but clinically irrelevant at this stage. + The intervention did not increase microbiome diversity compared to placebo. Alpha diversity was unchanged, and the taxa changes seen were only from pre- to post-analysis within each group. Between-group differences were limited, and the placebo actually showed similar or even potentially larger shifts. This means the observed changes fall within normal placebo-driven variability, not a real treatment effect. No global microbiota shifts were detected. Chicory inulin 12 g in constipation patients + 12 g of chicory inulin daily for 4 weeks (compared to maltodextrin placebo) + Global microbiota shifts: enrichment in butyrate-producing Bifidobacterium and Anaerostipes, and depletion of the pro-inflammatory Bilophila. +The effect was seen by comparing intervention vs placebo in a cross-over setting, a very rigorous type of clinical analysis in which each person serves as their own control, eliminating a lot of individual random noise. + The trial also met its primary objective by improving constipation symptoms in the targeted patient group. Resistant starch daily 30g for 12 weeks in older adults + Significant increase in Bifidobacterium in both middle-aged and elderly participants, with an increase in the beneficial microbiome byproduct butyrate, and reductions in Proteobacteria (including inflammatory Escherichia–Shigella) in the elderly. + Resistant starch also significantly reduced blood glucose, and produced greater reductions in blood insulin and insulin resistance (HOMA-IR) in the elderly group.

@robbyrussell We’re at 15 years and counting.

Unpopular opinion: The best thing about a 16-year-old Rails app is that it's survived 16 years of production use. That's not technical debt. That's battle-tested code.

@aviflombaum Reading articles on X is currently a terrible experience. cc @nikitabier

$100 not one person, including me, actually read this article.

@robbyrussell Oh my! You made the right call.

RE: github.com/ohmyzsh/ohmyzs…

One of the least glamorous parts of maintaining a popular open source project… You develop a sixth sense for Issues that are wildly outside the scope of what maintainers should be spending cognitive energy on. You read it. You already know how it ends. You close it anyway.

Avi is right, mine is #336, same username a X.

@brunotorious @obie Very cool Bruno. The Readme on the repos should definitely include these visuals.

Day 10 as CTO. My morning so far: Claude Code pulled my calendar, summarized my Twitter bookmarks, created 9 recurring 1:1s across 3 timezones, explored a codebase I worked on last night, and updated my knowledge base. All through conversation. This is the job now.

Amazing work by @AmandaBPerino and the dozens of others listed here👏🏼 The Rails Foundation is set to have its best year yet in 2026, and I’m very much looking forward to Rails Word Austin, TX.
