F1 won't let a car start a race if it qualifies more than 7% off the fastest pace. But the autobahn lets a car doing 75mph share the road with one doing 175. Can someone explain to me what's the rationale of having no speed limit? How is this not massively endangering others?

The constant decel messaging in Europe is insufferable as an adult, but its effect on kids is worse. As a parent, it's your obligation to counterprogram this nonsense. Show them robots, rockets, and wonders of AI. Show them cathedrals and moon landings. Instill hope in progress.

The IRS has a mobile app today because of a conversation in December. @shl had just come out of DOGE, where he wrote publicly about what he found inside the federal government. Most of it was not what people expected. His line was that the government is pretty efficient and could move faster, and that the obstacles were legal and procedural rather than a shortage of talented people. @SamCorcos recruited him to the IRS. Not as a contractor, not as a temporary detailee. As a career employee, A civil servant. At a public event that month, @shl asked the room whether the IRS should have a mobile app. Everyone said yes. Obviously yes. The IRS processes roughly 160 million individual returns a year on a system written in 1960s COBOL, and taxpayer-facing technology there has been a decade behind the private sector for most of living memory. Less than a year later, the app is live. That is the model working exactly as designed. Put builders inside the agency, and let them ship. No statement of work. No eighteen-month procurement. No vendor whose incentive is the renewal. Every agency in the federal government should be operating the same way.

Yesterday I did a proactive whole-body MRI at @prenuvo for early cancer screening and other diseases. Luckily no worrisome or high risk findings. I had a few minor findings (common and benign things), and the explanation and reassurance was very well done in the report. The MRI even detected a lingering sinus infection I've had for the past 4 weeks! The images you get of your body are incredible too. It can't possibly hurt (except the pocket; it's $2,500) to do these regularly and monitor changes over time. Their MRI setup is quite nice too. They are a bit more spacious than the ones I've seen at hospitals, but most importantly they put special glasses on you with a 45° mirror that lets you watch a movie projected behind you. (You choose the movie/show.) Makes a huge difference for claustrophobia because the space feels much bigger when looking through the mirror. It's also nice you can see a clock in the screen, so you know approximately how much time you have remaining inside the magnet. Overall, impressed.

Buy your kids an AI subscription. Look what they did in 30 minutes. The house is full of laughter. Buying tokens for kids in 2026 is like buying a PC in the ’90s. Unenlightened parents think it’s just an expensive toy. Progressive parents open opportunities for kids to learn the future from a young age. $20 a month is nothing.

X ads used to be terrible, but they seem very compelling now. You can target the followers of accounts you handpick, and you often get a cost per click in the 6c-10c range. Also, it seems like engagements from ads boost organic reach. For example, the ad may bring 1M impressions, and the same post gets another 2M impressions organically, presumably boosted by the engagements from the ad. I've seen this happen many times in the past 4 months. Some people try to reduce the ads they see on the platform by blocking every account they see running an ad, so there is still a downside that you get mass blocked by thousands of people. But it might still be worth it if you want to get a spike of attention to something important you want to promote.

Got the car back after @Kia escalated when they saw my tweet. They had it for two weeks of testing, and did a software update. Just 5 days later, the 12V battery is dead again showing just 2.75V! 😡

HEY what!? HEY yes! The HEY CLI and TUI is out! Calling all terminal dwellers, automation aficionados, and agents. Get your CLI right here: The CLI allows you - and your agents - to do almost everything the web, desktop, and mobile apps do. You can compose emails, reply, forward, trash, mark as spam, ignore, label, clip, note, and share. You can create events and to-dos, and even track time. And yes, the HEY Calendar is TUI enabled as well. And BTW, if you use Omarchy it'll pick up your themes too. There's also a menu bar plugin that'll be installed with the CLI. Check out more here: Have at it! More HEY goodness is on the way. Got some good stuff brewing. Not on HEY yet? Now's an especially good time to jump on board at

You can take your pompous code of conduct and send it into the sun. It was the CoC legalese and weasel language that armed the woke inquisition in the last turning. Never again.
