You can't trust doctors to know the full story today. Too much medical school propaganda. My doctor friends hate doctors, lol. Today you need other approaches based upon evidence.

@daveasprey I hate my bipap but I’m used to it. Never missed a night. I have it set very low but enough to prevent partial airway collapse and it helps enormously. If you are determined you will make it work.

Your doctor will not tell you this. Most CPAP patients hate it and abandon it within months. Their oxygen crashes at night. Their mitochondria suffer. Their glymphatic system cannot clear amyloid beta. A clinical trial just completed on Nastent. It is a nasal insert you wear at night. No mask. No claustrophobia. No straps. Patients in the study actually used it, night after night. Here is what the data showed: efficacy for snoring and apnea events. Safety solid. Acceptability high. People did not dump it after two weeks like they do with CPAP. I tested dozens of sleep devices. The barrier to any sleep tool is compliance. A device your body rejects sits in a drawer. This one people tolerate. Your mitochondria need oxygen at night. Your brain needs deep sleep to clear metabolic waste and prevent cognitive aging. If CPAP failed you, talk to a functional medicine doctor about Nastent. The research is real. Your sleep quality depends on it.

@MrAhmadAwais is command code good for writing such as creating branching quizes and other advanced copy tasks

What should Command Code ship next?

Codex v. Claude Code. Claude Code is a much better writer than Codex, much better. Codex is a better coder than Claude Code. Claude Code is more fun and better to discuss things with, although you can get Codex to do that if you use a skill that you create that makes it more verbose and less likely to just jump into the doing and stick to the planning.

@theficouple CD is fine. In Texas there is no state income tax. If it was California I’d suggest short term treasury’s. I agree. I wouldn’t be blindly putting money into the stock market now either.

Spoke with a doctor from Austin, TX: They currently have $140,000 in a savings account. Considering putting it in the S&P 500 but worried about value now being all time high. May instead put their money in a 12 month CD giving them guaranteed 4.5%. ...What would you do!?

@FedotOff90 Lesson is sell any shit regardless of what works. Which I think is a bad lesson.

Random conversation at a gym in LA changed how I think about ecom niches. Guy next to me between sets mentioned he sells a prostate supplement. Doing $2.1M/month. I almost laughed. Prostate supplements. Not exactly the sexiest product. Then he showed me his margins. 41% net. Over $860K/month in actual profit from one product that nobody in his social circle knows about. He said: "Everyone wants to sell the cool product. Pre-workout. Collagen. Greens powder. Those categories have 500 brands fighting over the same 25-year-old gym bro. Prostate health? My customer is a 55-year-old man with money who doesn't price shop. He sees an ad that speaks to his exact problem, he buys, and he reorders every 3 months like clockwork." His US subscription retention rate: 71% at 6 months. Average customer lifetime value: $430. He's now expanding into Germany and Japan — two countries with rapidly aging populations and almost zero competition in the prostate supplement space on Meta. But with a different model for Europe. No subscriptions. High-AOV bundles (3-month and 6-month supply packs), post-purchase upsells, and email reorder flows timed to when the product runs out. He said the European margin model is different but the profit per customer ends up similar because the upfront AOV is so much higher when you force bundles instead of single units with a subscription checkbox. He found both markets by scanning competitor activity on GetHookd — searched prostate supplements in Germany and Japan and saw almost zero brands running. That empty search result was all the validation he needed. The lesson: the "boring" health niches that nobody wants to talk about on Twitter — prostate, menopause, blood pressure, joint pain, vision — are where the real money is. High AOVs, loyal customers, zero competition from the influencer brands. Stop chasing the trendy supplement categories. The unsexy niches print harder and longer.

@sweatystartup I fired a whole bunch of people because of AI. What are you talking about? We're doing way more with way fewer people. We're a small business.

All the AI hype I’ve yet to see a single person actually show me how they are replacing employees with AI. Show me!!!!!!

@SimonHoiberg @steipete I just made one in 10 minutes on Codex and am using it. It grills me, it argues, and it builds a shared vocabulary and explores all the questions it can think of as we talk. It’s awesome.

@CookResearcher I've tried, but it's very little effective. Maybe a skill/config I don't know about @steipete?

GPT 5.5 is so good at doing stuff. Tool calling, searching, coding, handling long, iterative jobs. Incredible. It's still horrible to talk to/brainstorm with. It will agree with everything I say. Rarely push back (unless I tell it to, but that defeats the purpose). It'll tell me how great my questions are and that all my ideas are amazing. If I correct it on anything (even if my judgement is clearly wrong) it'll tell me I'm "absolutely right" Sigh.... Opus is such a pleasure to talk to in this regard. Gemini also (even though the empathy thing is super annoying, but it will at least push back and challenge/correct me if I'm wrong). Why is GPT 5.5 still such a doormat? It's infuriating.

@Its_Nova1012 CPM and MS-DOS

What was the first Operating System you ever used? - Windows - Linux - MacOS And what are you using now?

@bindureddy Kimi and Deepseek are nowhere near as good as the best of OpenAI and Anthropic. They are amazing but nowehere near as good.

Kimi 2.6 and GLM 5.1 are insanely close to closed AI in performance The only issue is speed. I am hopeful the open source models will soon solve them We are moving to open source on all batch jobs. Closed source APIs are extremely expensive with AI labs maximizing API margins 🤷‍♀️

@helloiamleonie I use claude code for writing. It's brilliant. I also use local models (Qwen usually) and Codex but Codex isn't as good a writer as Claude, although useful and I do use it a lot for that.

Agent harness for writing instead of coding. Anyone working on that? Any recommendations? (Please don’t tell me Claude Code unless you have a workflow that’s actually good)

@jonbrooks There is huge over building of luxury condos in St. Petersburg. Not sure who will buy them. Luxury apartment rent will come down as the condos are repurposed to rental units, but where is the market for those.

Florida has a wealth divide problem. We build $700k “luxury” homes… in a state where much of the workforce makes $15/hour. Who exactly is the next marginal buyer? That’s the only question that matters.

Google ads (YouTube) were always much better than Meta for us over the years. But their flagging our ads was a constant nightmare. Never reasons given. Now, it suddenly changed. Their AI tells you what is wrong and why your ad was flagged so you can fix it. A game changer.

@Mr_Findependent @SteveOnSpeed And after your FRA, all the money you get from other income is yours and you get your full social security.

I actually instructed my working parents to wait until 67 because if you haven't reached your full retirement age, $1 in benefits will be deducted for every $2 you earn above the annual earnings limit ($23,400 in 2025) In the year you reach your full retirement age, the reduction falls to $1 in benefits for every $3 you earn above a higher limit ($62,160 in 2025)

People say wait until 70 for max Social Security. Wrong. Claim at 62, invest it, and you'll have $220K+ in liquid capital by 70, while the "wait" crowd has collected $0.

@SteveOnSpeed What about the fact that your social security at that age is diminished by income on other businesses or salary?

@MushtaqBilalPhD I’m donating 10% of every US$ I receive to Elsevier.

Evil websites like Libgen, Z-library, and Sci-Hub had pirated millions of academic books and papers. They've been shut down, and rightly so. We shouldn't use them anyway. We should make billion-dollar academic publishers richer. Anyway, here's how to access these libraries: 🚨DO NOT DO THIS!

@DonnaNewro88524 I’ve been doing this for many years. Sold my Virginia home and living on in Florida. But I will probably get another place in the North. it’s just a bit boring to spend summers in Florida.

Good morning from Florida. We live in New Jersey, we just bought a home in Florida. We are fixing it up. Going back to New Jersey for the summer and coming back in September. Hopefully, we will be making this permanent within two years. Sadly, the NJ i knew, doesn’t exist.🥲

@BryanECano This is incredibly exciting!

Instructions for CLI – requires access token setup. If you're creating internal tools shared across multiple team members, this may be a better route. Took me 10 minutes to set up. Developer: developers.facebook.com/blog/post/2026… Developer Documentation: developers.facebook.com/documentation/…

🚨 Meta released their Ads MCP and CLI today – if you use Claude or ChatGPT you should install this asap (resources in comments). What makes this announcement so interesting is that it gives AI tools direct, authorized access to help manage your Meta Ads account through natural language. 1. Comprehensive reporting Pull detailed reports, surface performance trends, and quickly understand what is happening across campaigns. 2. Campaign management Create and edit campaigns, ad sets, and ads without manually clicking through Ads Manager. 3. Catalog management Create product catalogs, add product data, and troubleshoot feed issues faster. 4. Signal diagnostics Access signal health and quality insights so you can prioritize the parts of your setup that need attention. This is a huge step forward in agentic media buying. Will be testing this rest of the week!

@BarbellFi This will make you go broke due to inflation. Even in a few years, 50K isn’t enough to live on. Even this year. And wait until food and energy prices skyrocket even more.

I’m 36 & want to retire now 30 year treasury yield is 5% My annual expenses are $50k I can buy $1 million of these bonds Get $50k/year to cover my expenses For 30 years Get my $1 million back in 30 years Then at 65 collect social security I’m strongly considering this 😳

@sweatystartup that’s excessive. But protein does suppress appetite pretty reliably. If you have high protein, high carbs, and low fat, you can probably lose body fat safely and preserve lean mass.

99% of the people shoveling 150+ grams of protein are working desk jobs and have 25%+ body fats. Wtf are you doing? Wake up!

Normal people eating 150-200 grams of protein daily will go down as as big of a disaster as the lead pipes that took down the Roman Empire.
