Really excited to announce Root Ventures Fund 4, our new $190M seed fund supporting technical founders working on hard problems with up to $5M at any stage with “seed” in the title. We are so grateful to @EricNewcomer for perfectly capturing our vibe in his article below: 👇

Can someone explain to my why we are not at least as alarmed about adult innumeracy as we are about adult illiteracy?

And even worse, I bet most people’s reaction to this would be “so what?” When you can’t even reason about a trivial real world system mathematically without 4 grade levels of math above this extremely low bar.

Basically the entire population is already functionally innumerate despite taking quite a lot of math for 12 years, and the reason has nothing at all to do with the impacts of technology.

It is high time to stop commenting on the controller being XBox. Controllers are simple technology. The ones designed for gaming consoles are both reliable and ergonomically designed. It is stupid to replace them with custom controllers and therefore never newsworthy. /end rant
BREAKING: The U.S. military is now reportedly using high-energy laser weapons in the Strait of Hormuz to shoot down drones and incoming cruise missiles - with some systems operated using modified Xbox-style controllers. The New York Post reports the directed-energy systems are being deployed against Iranian threats at a fraction of the cost of conventional interceptor missiles. The controller technology itself is not new: U.S. laser systems have previously been demonstrated with gamepad-style controls designed to make them easier for soldiers to learn and operate. Defense Secretary Pete Hegseth personally tested one of the systems during a June demonstration at White Sands Missile Range, where directed-energy weapons were used against aerial targets. The lasers are invisible to the naked eye and disable targets by concentrating energy on a small area until critical components overheat or fail. The confirmed deployment highlights the growing link between space and missile defense: U.S. satellites increasingly provide the warning and tracking data that helps terrestrial systems identify and engage incoming threats.

After years of attempting to stop Waymo over safety, the argument is over and Waymo is safer. Local socialists will now pivot. Which should be swiftly dismissed. They don’t want safety. They don’t want transportation. They want to endlessly critique our safest transportation.
Waymo says after 271 million driverless miles, its vehicles were involved in 82 percent fewer injury-causing crashes as compared to human drivers. theverge.com/transportation/…

Thoughts, @JackieFielder_?
Waymo says it has stopped 841 injuries in 271 million autonomous miles electrek.co/2026/09/24/waymo…

As a career-long hater of code review, I was fortunate enough to be wrong for long enough until I was eventually right for unrelated reasons.

Who is doing World of Warcraft but every quest is just an agent task handed to you by a manager?
Chads.. you can now chat and vibe code with Claude while playing WoW Forever. Open a chat window in game, send Claude a task, go back to leveling. It pings you when it's done. No alt-tab, no /reload. Link below. #worldofwarcraft @Asmongold wow-claude

"Taste is all that matters now" sounds trite. But I am currently installing a second operating system on my primary computer because I liked a song on a webpage so. It might not be far off base...

Take a Waymo. Save a life.
270M+ miles. 841 fewer injury-causing crashes. Our latest safety data shows the Waymo Driver continues to make roads safer for everyone. Compared to human drivers across 5 territories, it reduced: 📉 Injury crashes by 82% 📉 Serious injury crashes by 95% Full data: waymo.com/safety/impact

Software will never die again. You liked Google Reader? Cool, you can generate and deploy your own. Yours, forever.

I think everyone spends 2 hours in front of opus and then assumes that professionals are cooked. Those professionals will spend 2000 hours in front of opus and you haven't seen what they will make yet.
Ever wonder what $1874.40 of Opus 5.5 tokens looks like? Wonder no more. I highly recommend watching the whole video on 1080p on a large screen with sound on. Pay attention to all the little details. - Birds flying and diving into the ocean. - Cloth, signs and lights swaying in the wind. - Crabs scuttling along the shore and burrowing when you get close. - Fish swimming alongside the whale. - Lights illuminating the dock at night Then zoom out and see the entire island. Never dipping below 60 FPS at 1440p resolution. Yes, there's a few bugs and visual artifacts, some textures need improving, the shorelines waves sometimes look funny, but these are so trivial to fix at this point. FYI I'm on the $200 subscription plan. This used 59% of my weekly usage and took 2h 7h of API time using multiple subagents, about 8h in real-time. There was extremely little technical direction here. 99% of my prompts were "Add X and Y" or "This looks weird, make it better". It's a great time for hobbyists, bad time for professionals. This experiment has further cemented my view that technical creatives are about to experience a massive disruption.

This talk is brilliant. It makes it basically impossible to be speaking at a developer conference tomorrow about this topic but not be this exact talk.
Clearly, this @DHH Rails World 2026 keynote has become an instant classic. piped.video/watch?v=V9SxpJpH… Highlights: - WebApps are dead since it is so cheap, easy, and fast to build native apps with agentic coding. - No need for a framework like Ruby on Rails if you can achieve the same functionality with e.g. Rust on the backend while saving a lot of money by reducing the number of needed servers and having a faster application. - Your application needs a CLI. Because agents love command-line tools.

So @dhh just told 1000 rails programmers “accept that it’s over” Last words of the opening #railsworld keynote were “don’t be a f*cking loser” and then he walks off Glad I’ve been through the existential dread phase already, cos I’m ready to run through a damn wall right now!!

Trolling Connie Chan is a long-standing San Francisco tradition and a wholesome activity for the whole family.
local teens were horrified to learn Connie Chan wanted cars in the park they ride through every day. they wanna be TikTok stars so they asked me to record them "approving this message."
