Are mentions like @jqrd@hachyderm.io still blocked over here? Are you moving over? I still use both, but what I get out of each one is quite different!

Yesterday Mark Cuban reposted my work, DM'd me, and told me to keep telling my story. So here it is. I'm a Master Electrician. IBEW Local 369. 15 years pulling wire in Kentucky. Zero coding background. I didn't go to Stanford. I went to trade school. Every week I'd show up to a home where someone just bought a Tesla or a Rivian. And every time, someone had already told them they needed a $3,000-$5,000 panel upgrade to install a charger. 70% of the time? They didn't need it. The math is in the NEC — Section 220.82. Load calculations. But nobody was doing them for homeowners. Electricians upsell. Dealers don't know. And the homeowner just pays. I got angry enough to build something about it. I found @claudeai. No coding experience. I just started talking to it like I'd explain a job to an apprentice. "Here's how load calcs work. Here's the NEC code. Now help me build a tool that does this." 6 months later — @ChargeRight is live. Real software. Stripe payments. PDF reports. NEC 220.82 calculations automated. $12.99 instead of a $500 truck roll. I'm still pulling wire. I still take service calls. I wake up at 5:05 AM for work. But something shifted. Yesterday @vivilinsv published my story as Claude Builder Spotlight #1. Mark Cuban saw it. The Claude community showed up. And for the first time, I felt like this thing I built in my kitchen might actually matter. I'm not a tech founder. I'm a dad who wants to coach little league and be home for dinner. I just happened to build something that helps people. If you're in the trades and thinking about using AI — do it. The barrier isn't technical skill. It's believing you're allowed to try. EVchargeright.com

@SydneyLWatson Academic performance also correlates with how much older a kid is than their year group.... go figure

Texan boyfriend just explained that we aren't allowed to have an August-born child, because that child will be the youngest in their class and therefore, when they play sports, will be smaller than all the other kids and therefore will have a harder time. Is this seriously the shit you guys think about? He's not joking either. I genuinely don't know what to do with this. Planning kids around them playing football is so America-coded though lmao. 😂

@strzibnyj @trendradar_app You might enjoy Microsoft's Sculpt keyboard. Or go wild and go for a ZSA Moonlander for the full split :)

@trendradar_app I am sticking with my Lift mouse, there is nothing better. Just thinking about keyboard. I have Microsoft Wave and it's really good too.

I should probably order a new mouse and keyboard soon. I might go for the same what I have but if you have a keyboard suggestion you swear by, I am all ears.

@GergelyOrosz I started at Microsoft as an SDET, moved to SDE and a year later or so the merge of roles happened. In my teams there was never any doubt about who owned writing UTs -- SDEs. Before SDETs there were STEs. Shipping cadence didn't change immediately as part of the role merge.

When you change how you ship software, roles around it can drastically change. A decade ago, Microsoft had the SDET role on most teams, because software was often shipped weekly/monthly or even less frequently. When this changed to several times/day the SDET role got in the way

@nayibbukele Misleading question. Ask about the head of state term limits. In most European countries the head of state is not the head of government, thus they are not susceptible to falling into dictatorship.

90% of developed countries allow the indefinite reelection of their head of government, and no one bats an eye. But when a small, poor country like El Salvador tries to do the same, suddenly it’s the end of democracy. Of course, they’ll rush to point out that “a parliamentary system isn’t the same as a presidential one,” as if that technicality justifies the double standard. But let’s be honest, that’s just a pretext. Because if El Salvador declared itself a parliamentary monarchy with the exact same rules as the UK, Spain, or Denmark, they still wouldn’t support it. In fact, they would go ballistic if that happened. Why? Because the problem isn’t the system, it’s the fact that a poor country dares to act like a sovereign one. You’re not supposed to do what they do. You’re supposed to do what you’re told. And you’re expected to stay in your lane.

@sallepierrelamy @Acyn @AOC You mean other than "how did I do that?" He's clueless.

@Acyn @AOC ¿Why isn’t his answer included in the video?

AOC: Your agency nearly doubled the taxpayer dollars that for-profit insurance corporations like United will be paid next year, meaning these companies, the largest of whom is under criminal investigation by the Trump administration, will be receiving an additional $25 billion from your agency. RFK JR: How is that happening?

Did i just enjoy that 20 min Apple ad with Stormzy? Yes I did.

@raoulsnotes The revert mentioned might explain why our previous deploy from over 24h earlier got somehow replayed and dynos started "gracefully shutting down" one by one without coming back up, which caused us 1h of downtime, towards the end of their outage.

Honestly surprised that the Salesforce incident page has more details than the Heroku status page:

@SergioRocks Overly commented code.

Your colleague opens a PR. You're the reviewer. How can you tell that most code changes were written by Cursor/Copilot/etc? What's the one thing that instantly gives it away?

@thdxr Misdirection. The real reason people (middle class and working class) are getting poorer? Look up Gary Stevenson on YouTube.

saw something i keep thinking about - talked a bit about it on the podcast with tariffs there's two potential intentions 1. end goal is free trade, tariffs are a strategic lever to get there 2. end goal is to bring manufacturing back to US it cannot be both (lot of people claiming both) ultimately i know trump is chaotic so he might flip from one goal to the other depending on how things are going that week so we can ignore that but i saw an interview with an economist developing policy for the "new right" that surprised me ultimately i disagree with him but he is not dumb and is not wrong about most things to start - he 100% genuinely cares and is focused on helping middle class and below americans his view is that their lives have continued to get harder - pretty much word for word what the left typically speaks about and his solution is to dismantle the way the american empire works today and to retreat from the world - including militarily he does not believe it has been good for most americans and while he probably wouldn't support large tariffs overnight the long term the end goal without a doubt is not free trade so whether or not the trump tarrifs stick (idk if he can personally tolerate the pain) there is this new effort that looks very different than what i imagine republicans would typically be for and if communicated well i can even see a lot of people on the left supporting it

We're in 2025 and I accidentally made `claude-3.5-sonnet` dump his system prompt. -- gist.github.com/tsilva/530bbb6…

@awilkinson The only thing that comes to mind is the Mochary Method. Hire one (or more) "chiefs of staff" (not EAs!) that you'll eventually trust to almost autonomously run subsets of your portfolio. Add checks & balances. PS: I haven't had this problem myself! mocharymethod.org/chief-of-staff…

I’m a bubbling pot of stress today and, as I think about it, I’ve realized that it’s entirely because of my calendar. Nothing stresses me out like tetris game of a calendar. It’s my white whale. The thing that I have never been able to tame or conquer.

I’ve tried a bunch of different strategies: 

 • A 2-3 hour booking window (results: booked 4+ months out, plus important company issues or CEO calls getting jammed in last minute = 4-6 hours a day of meetings and activity and no deep work)

 • Having no calendar at all, just calling people (result: a massive call list that I can never get on top of, as well as a lot of people being offended when I won’t book with them)

 • Calendly (results: a lot of meetings I don’t want to do booked into eternity)

I’m at the point where I’m ready to declare calendar bankruptcy and I want to tap your collective intelligence. 

The core issue is that I am an inch deep and a mile wide. I oversee over 40 companies, I have hobby businesses, I’ve got 150+ minority investments, I’m trying to do a podcast and this newsletter, I have a broad ranging, highly extroverted social life, and I’m a father of two who often has to travel for work. TLDR: My ambition exceeds my time.

I’m curious to hear from other people who nod along with this and have significant work and personal responsibilities. How do you handle this? How have you prioritized? How do you delegate some of this? Please respond to this thread on if you have any ideas (systems, delegation workflows, heuristics, etc), I’m all ears!

I have been passionate about dotnet since 1.1. But these days, I'd advise people to invest in learning Go and Javascript/Typescript instead. That's where I see the most option value is. 3/3

But because of the self reinforcing negative loop, it's hard to attract the same talent to the dotnet world. I've seen from the inside how amazingly talented people at Microsoft are with dotnet. Even more impressed with the boundaries Unity continues to push. 2/

And here is one of the main hurdles of dotnet. It's been cross platform for ages, both development and runtime. You can get extremely far without needing to open Visual Studio. You can deploy on Linux. Managed SQL server is more expensive but you can use any DB. 1/

Daniel Kahneman passed away today He changed the world of behavioral finance Here are 10 things I learned from his book Thinking Fast and Slow as a way to say thank you:

What now folks?

Amazing project and definitely the best demo ever! youtu.be/sC1B3d9C_sI?si…

@jmwind Well this took off a bit! The irony is I'm actually head of eng at work and that always requires some process... but yeah I love to focus on delivering stuff, having impact and being agile -- but not Agile with big A! Finally, credits to @lzsthw, the author of the manifesto.

@jmwind Reminds me of this: programming-motherfucker.com

I’ve retired from software… process. No scrum, dds, tdd, stand ups, devops, sre, micro services, retrospectives, pre and post mortems… Instead, we just build and run software together. We do use an issue tracker and a good readme. Everyone posts an eod update to our group with demo/insights from their day. Plain and simple. It’s pure bliss.
