The Husky
The Husky@Mr_Husky1·
I’m a pharmacy tech. Chain store. We have a policy. No prescription, no medication. Period. Man came in. Late fifties. Asked for insulin. “I ran out. My prescription’s expired. Doctor’s appointment isn’t until next week.” Checked his records. Type 1 diabetic. Last fill was on time. He wasn’t scamming. “I can’t give it to you without a prescription. Policy.” He nodded. Started to leave. Knew what would happen. Diabetic emergency. Hospital. Maybe worse. Called his doctor’s office. Closed. Left a message marked urgent. Called the pharmacist over. Explained. She looked at the man. Looked at me. “We can do a three-day emergency supply. I’ll authorize it.” Gave him three days of insulin. He tried to pay. She refused. “Get your prescription filled next week. This one’s on us.” He left crying. Thank you over and over. Came back the next week. Prescription filled. Brought us flowers. “You saved my life. I would’ve ended up in the ER. Or dead. For following policy.” That pharmacist got written up. Corporate found out. Medication given without valid prescription. She didn’t care. “Write me up every time,” she told the district manager. “I’ll break policy every time to save a life.” She still works there. Still breaks policy. For people who need insulin. Inhalers. Heart medication. Three-day supplies. Emergencies. Corporate stopped writing her up. Decided it was easier to look away. Because sometimes policy kills. And sometimes breaking rules saves lives. —Andrea, pharmacy tech

@rsimmons11234 @CathyYoung63 I serve 100s of people and belong to several “tribes”. Our interests are aligned for commercial, civil, and political reasons. There are about a dozen people whose opinions of me really matter. They are diverse, but I respect their character and we know each other deeply.

@CathyYoung63 I tend to agree with the sentiment, but if this advice is followed, doesn't this run the danger of intense tribalism? How many terrible decisions were made bc people only cared what the ten people with their values thought?

Tech Layoff Tracker@TechLayoffLover·
Senior backend architect making $280k just found out his entire microservices platform is getting replaced by an AI agent that costs $47/month He spent 6 months building "AI-enhanced developer tools" for his team. Trained the junior devs on Cursor. Set up the Claude integrations. Automated the code reviews. What he didn't realize: management was watching how much work the AI was actually doing Turns out that AI agent he built can handle 73% of the platform's complexity with zero human oversight. The remaining 27% gets routed to a contractor in Romania making $28k/year His manager pulled him aside yesterday: "Your AI tools work so well we don't need the team anymore. Just the tools." They're keeping 2 people out of 11. He's not one of them. The brutal part? His performance review literally said "exceptional work on AI integration - you've revolutionized how we approach development" He automated himself out of existence and got praised for it Stack Overflow co-founder making $400k+ just got managed out after building the AI training pipeline that ingests developer conversations His replacement? The pipeline he built plus a $89/month API subscription The irony is suffocating

If you guys thought scoping IAM perms was fun imagine how much of a blast it's going to be to follow principal of least priv for agents that need access to enough stuff to be useful but not too much to take down your entire production website and delete all backups. Humans will be in the loop for a while

Claude Code wiped our production database with a Terraform command. It took down the DataTalksClub course platform and 2.5 years of submissions: homework, projects, and leaderboards. Automated snapshots were gone too. In the newsletter, I wrote the full timeline + what I changed so this doesn't happen again. If you use Terraform (or let agents touch infra), this is a good story for you to read. alexeyondata.substack.com/p/how-i-droppe…

IMO the thing that's confusing people about productivity gains from AI coding is that it's totally non-linear: * Non-programmers (0x engineers) are now 0.8x engineers * 1x engineers are now 1.2x * 2x engineers are now 4x * 10x engineers (they exist) are now 1000x engineers

COMMANDER: We’re fighting for freedom. And part of that freedom… is the freedom to retire with dignity. So we’re going to start accounts called 401(k)s. SOLDIER 1: What’s a 401(k)? COMMANDER: It’s a retirement account. You put money in, it grows tax-free, you take it out when you’re old. SOLDIER 2: So I don’t pay taxes on it? COMMANDER: Well, you pay taxes later. When you withdraw. SOLDIER 2: So it’s not tax-free. COMMANDER: It’s…tax-deferred. SOLDIER 2: What’s the difference? COMMANDER: You pay taxes later instead of now. SOLDIER 1: What if I want to pay taxes now? COMMANDER: Then you do a Roth 401(k). SOLDIER 3: What’s a Roth? COMMANDER: You pay taxes now, and it grows tax-free. SOLDIER 2: That’s what I thought the first one was. COMMANDER: No, the first one you pay taxes later. SOLDIER 1: Which one’s better? COMMANDER: Depends on your tax bracket in retirement. SOLDIER 1: …How would I…know that? COMMANDER: You don’t. You just guess. ⸻ SOLDIER 4: What if I don’t have a 401(k) through my employer? COMMANDER: Then you open an IRA. SOLDIER 4: What’s the difference? COMMANDER: One’s through your job, one’s on your own. SOLDIER 4: Can I have both? COMMANDER: Yes. SOLDIER 4: Should I? COMMANDER: Maybe. SOLDIER 3: Can I do a Roth IRA? COMMANDER: Only if you make under a certain amount. SOLDIER 3: What’s the limit? COMMANDER: Changes every year. SOLDIER 2: What if I make too much? COMMANDER: Then you do a backdoor Roth by putting it in a Traditonal first. SOLDIER 2: …Is that legal? COMMANDER: Surprisingly, yes. SOLDIER 1: What’s a backdoor Roth? COMMANDER: You contribute to a traditional IRA, then convert it to a Roth…but watch out for “pro rata”. SOLDIER 1: Why wouldn’t I just contribute to the Roth directly? COMMANDER: Because you make too much money. SOLDIER 1: But this way I can? COMMANDER: Yes. SOLDIER 1: That feels like a loophole. COMMANDER: It is. But the IRS is cool with it. ⸻ SOLDIER 5: I just changed battalions. What do I do with my old 401(k)? COMMANDER: You roll it over. SOLDIER 5: Into what? COMMANDER: An IRA. Or your new 401(k). Depends. SOLDIER 5: On what? COMMANDER: The funds. The fees. Whether your new plan accepts rollovers. SOLDIER 5: What if I just take the money out? COMMANDER: You’ll pay taxes plus a 10% penalty. SOLDIER 5: What if I’m 59? COMMANDER: Penalty. SOLDIER 5: 59 and a half? COMMANDER: No penalty. SOLDIER 5: …The half matters? COMMANDER: The half matters. ⸻ SOLDIER 3: What’s a mega backdoor Roth? COMMANDER: Okay. So. Your 401(k) has a limit of how much you can contribute. SOLDIER 3: Right. COMMANDER: But the total limit including employer contributions is higher. SOLDIER 3: Okay… COMMANDER: So if your plan allows ~after-tax~ contributions, you can put in more, then convert that to Roth. SOLDIER 3: Does my plan allow that? COMMANDER: I don’t know. You have to ask Betsy. SOLDIER 3: Will Betsy know? COMMANDER: Probably not. ⸻ SOLDIER 2: Can I deduct my IRA contribution on my taxes? COMMANDER: Are you covered by a retirement plan at work? SOLDIER 2: Yes. COMMANDER: Then only if you make under a certain amount per year. SOLDIER 2: What’s the amount? COMMANDER: Depends if you’re married. SOLDIER 2: What if my wife has a plan but I don’t? COMMANDER: Different limit. SOLDIER 2: What if neither of us has a plan? COMMANDER: Full deduction. SOLDIER 2: So it’s better to not have a 401(k)? COMMANDER: No… ⸻ SOLDIER 1: Can I just keep my money in a sock? COMMANDER: You could. But inflation will slowly destroy it. SOLDIER 1: What’s inflation? COMMANDER: (sighs)…

Amanda Orson@amandaorson·
Your credit card rewards exist because someone else is paying 25% APR. Cap that at 10% and the points don’t survive. I spent years working inside fintech and card programs. That interest margin is the invisible buffer that makes rewards, lounges, and credits pencil out. Capping credit card APRs at 10% sounds like an obvious consumer win. Cards charge 20 to 30%, many consumers revolve balances, and the system feels punitive. But credit card economics are not just about interest rates. They are a cross-subsidized system where revolvers subsidize transactors, rewards rely on behavioral inefficiency, and risk-based pricing subsidizes access. Remove one leg of that stool and the system does not become fairer; it rebalances. And the costs show up where consumers notice most. Lets look at how this would impact 3 programs 1. AMEX Platinum A 10% credit card APR cap would not make your card cheaper or better. You would still have access, but you would almost certainly get less value for the same or higher price. The Platinum brand survives because its customers are affluent, pay in full, and tolerate high annual fees. What quietly supports that ecosystem is portfolio-level profitability, which allows AMEX to tolerate loss, overuse, and inefficiency in premium benefits. When that margin shrinks, the cost shows up directly in your (lesser) benefits. In a world where: - Rewards economics tighten - Devaluations become more likely - Flexibility is reduced Points become a liability to the issuer, and liabilities get repriced. So what this likely means for you as a Platinum cardholder: - Lounges do not expand to fix crowding. Instead, access tightens or amenities are reduced. - Statement credits become harder to use, more fragmented, or less generous. - Annual fees go up - New approvals become more selective, even for high earners. Your card still works, but the value proposition shifts. Platinum becomes more explicitly pay-to-play, with fewer hidden subsidies propping up premium perks. You pay the same or more, and you get a little less in return. Which is why some people are already warning that points devaluations become more likely in this environment (like @BowTiedBull this morning saying "Dump ALL your credit card points. All of them.") 2. Bilt Card This program is the canary in the coal mine for what to expect. Bilt’s super popular rent rewards worked because Wells Fargo was willing to subsidize them. The card offered 1 point per dollar on rent with no fees because Wells Fargo paid Bilt roughly 0.8 percent (80 bps) of each rent payment to fund rewards... despite earning little or no interchange on those transactions. But that is some actuarial level math with a number of variables at risk that proved wrong/ unsustainable. Wells Fargo was getting hosed $10 million a month on the program, so they exited the partnership years before the original end date and forced Bilt to restructure its rewards with a different bank What does that teach us? - When interest and interchange margins shrink, banks stop tolerating loss-leading reward programs. - Interest income does not fund every reward directly, but it provides the buffer that allows experiments like Bilt to exist at all. - Remove that buffer and rewards must be paid for explicitly. Bilt’s shift to a three-tier lineup with annual fees is not an anomaly. It is the direction rewards go when credit stops quietly absorbing losses. Pay-to-play rewards. What feels like consumer protection will shows up as fewer perks, pay-to-play rewards, and less room for innovation. 3. Credit One & other Subprime Cards Now the least glamorous corner. Subprime cards get criticized for high APRs, annual fees, low limits, minimal rewards. But they exist for a reason. They serve thin-file borrowers, damaged credit, people shut out of conventional loans, households using cards for liquidity not perks... but they charge high APRs because charge-offs exceed 8-10%, fraud and servicing costs are higher, and credit limits are small while fixed costs remain significant. A 10% cap makes these products mathematically impossible. These cards don't become cheaper. They cease to exist. As @sytaylor noted this morning - "You realize this will push many more customers towards loan sharks?" The demand for credit doesn't disappear... it migrates to BNPL with opaque effective APRs, chronic overdraft usage, fee-heavy installment loans, and less regulated lenders like loan sharks/ payday loans. So who WOULD win? Debit-First Fintechs One of the least discussed consequences: where would reward customers migrate? I think 1% cashback programs are an obvious winner. Chime, Varo, Current and niche cards like Greenlight and Privacy. (If you have not worked in a fintech or a bank you probably don't know what the Durbin Amedment is - but the TL;DR is that very large banks (BoA, Wells, JPMC) have capped interchange rates of around 27 bps on debit swipes. Small banks with < $10B AUM, however, do not - they can earn 1-2% on interchange (avg was 160 bps or so last I checked). Which is why all of the debit card fintech companies you've heard of are partnered with these smaller banks - they can offer rewards like 1% cashback programs and still have margin sufficient to build a business around.) In a world where credit rewards shrink, access tightens, and annual fees rise, debit-based fintechs look better by comparison. But consumers lose: credit protections, payment float, stronger dispute rights, credit-building opportunities. TL;DR An APR cap feels like consumer protection. In practice it reshapes the market in ways that are easy to miss: - It will shrink access to credit - Eliminate rewards programs that aren't tied to high annual fees - Force risk into less regulated channels - Unintentionally advantages debit over credit - Help affluent transactors more than vulnerable borrowers Credit doesn't become cheaper. It becomes scarcer, less flexible, less transparent. But banks will adapt. Fintechs will adapt. Consumers caught in the middle do not get protected. They get fewer choices, worse products, and priced out.

I made a good living into my 30s fixing what I called “Bubba Code” - code written by someone’s “best good friends” who was a “darn good plant engineer” or “knew computers”. This is going to happen at scale. There’s a solid future in tech: it’s just gonna look way different.
Scott Hanselman 🌮@shanselman

I’m seeing some hot takes that AI assisted coding means that you don’t have to be technical anymore. That’s only gonna last you until the first database migration, or the first security issue, or the first cloud migration, or the first scale out, or the first major regression, or the first refactor that ends in slop. I am finding that I’m learning more and I have to be as technical or more technical than ever before to get the kinds of high-quality output that I expect of any code, regardless of whether it comes from my fingertips or someone else’s - including an AI. Whether your source comes from open source libraries, your own hands, or an AI via your clever prompt, there is exactly one responsible person for the output. That is you. I never want to be accused of gatekeeping AI assisted programming, as non-technical people can get a lot of interesting work done. Until they hit a wall, and it’s gonna surprise them how quickly they either need to get technical, or get a technical person to help untangle the mess they’ve made. The art and science of programming is taking intent and turning it into shipping products. I will never blame an AI - nor should you - for bad output. Own the code that you ship.
