Ferrari has just officially unveiled its first ever all-electric car, called the Ferrari Luce. • Starting price: $640,000 • Interior co-designed with Apple's former head of design, Jony Ive • Range: 280 miles (expected EPA) • Peak charging speed: 350kW • 122 kWh battery • 1,050 horsepower • 0-60mph: 2.4s • 800v • Four-door four-seater • Four electric motors • OLED screens • Weight: 4,982 lbs • Front motors spin to 30,000 rpm, rears hit 25,500 rpm • Car uses an accelerometer to capture real vibrations from the electric motors & rear chassis. An algorithm filters out unpleasant frequencies and amplifies only the more “musical” sounds. This can be heard inside and outside the car. • Paddle shifter on steering wheel changes how aggressively torque is delivered, with five different levels • The trunk has 21.1 cubic feet of space, the largest luggage capacity the company has ever offered • 197.6 inches long, about as long as a Tesla Model S U.S. deliveries start in Q2 2027.

I did it 👍 thanks @levelsio for sharing. Setup @Tailscale on my @Hetzner_Online VPS 🙌 Installed @claudeai on VPS 🤞 All my sites run through @Cloudflare tunnels 😎 Got @TermiusHQ running locally on my Mac and iPhone ❤️ Locked all the ports 💪 Migrate 25GB of projects, websites, apps onto my VPS. All MD files there as well 🏋️‍♀️ Then went shopping with the wife while coding from my phone and I’m no coder. This means I can check daily tasks, fix minor bugs and constantly and work on our main Shopify site. I’m launching a daily deals section all automated with resend but I can build and tweak that without needing to be at my MacBook. And if someone says you should be present when shopping. Fuck that. I’m present when 99% around my family and kids.

@FlyaKiet @superset_sh in case your PR dont resolves this: "it's Superset.app's host-service.js auto-polling git status (the wrapper app you're runningClaude inside). It spawns git diff every few seconds; each one gets stuck on the locked .git. Can't kill Supersetwithout ending this session.

@FlyaKiet @superset_sh Here it added a new tab "Terminal" which is another worktree session - and it's not clickable it's stuck and actually from another worktree.

Personal update: I've joined Anthropic. I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D. I remain deeply passionate about education and plan to resume my work on it in time.

Någon kanske skulle förklara ränta-på-ränta för Lovable? Efter 20 år tjänar en anställd som började på 50 i månaden plötsligt över 300 papp. 😅

Today we're launching @pitdotcom, with $16M funding led by @a16z. For ten years at Voi and other companies I watched something that drove me crazy. Smart people hired for their judgment, spending evenings reconciling data between systems that were never designed to talk to each other and chasing approvals over email at 11pm. Work that had nothing to do with why they joined. So we started building custom AI systems internally to take that work off their plates. Across Voi and Klarna the founding team had been doing this for years, because nothing on the market could actually do the job. The systems worked, but each one was a fragile one-off we couldn't hand to anyone else. Pit is what we wished existed back then. A platform that learns how your business actually works and builds the AI systems that run it for you, with enterprise security and governance from day one.
Adam Jafer@mradamjafer

Today we're launching Pit, with $16M in funding led by a16z. For 20 years, companies have adapted themselves around rigid software, leading to broken workflows and a quiet loss of productivity. With AI, that model breaks. For the first time, companies can run on systems designed around how they actually work, and give back time to their people. We're already seeing large enterprises replace manual operational work with AI-native systems built by Pit. They move faster, scale better, and free people up to focus on higher leverage work. We built Pit because we experienced this pain first-hand at companies like Voi, Klarna, and Zettle. Today, we're also announcing our $16M round led by @a16z, together with some incredible founders and operators from OpenAI, Anthropic, Google, Revolut, Deel, and many more. This is the strongest team I've ever been part of. And we're just getting started.

Logging your daily habits should help you understand yourself better… but can often feel tedious, repetitive, and easy to skip. That’s exactly what we’re fixing in our latest product update. Keep reading to find out what’s new. 👇

Cut the public funding to outlets like Dagens ETC that can’t survive on their own. I support a diverse free press and different political viewpoints. But not when tax money (100M SEK last 5 years) subsidizes propaganda that attacks the entrepreneurs and companies generating the billions in tax revenue that pay for it. ETC Chief editor attacks tech founders building real value and jobs, while the outlet lives off press support - including a history of repayment demands for incorrectly disbursed subsidies in 2018 - and while he buys multimillion-kronor apartments in central Stockholm. That’s not independent journalism; it’s greed and politicized propaganda that doesn’t benefit Sweden or its tax paying citizens. Let readers and the market decide what media lives or dies. End the subsidies.

**Dagens ETC (ETC-gruppen) har fått betydande skattefinansierat mediestöd/presstöd de senaste fem åren (ca 2021–2025).** Enligt offentliga uppgifter och rapporter: - 2022: ca 20,3 miljoner SEK (driftsstöd) - 2023: drygt 20 miljoner SEK - 2024: 17,3 miljoner SEK (enligt tillgängliga siffror) Tidigare år låg det ofta runt 20 miljoner årligen. Totalt för perioden uppskattas det till cirka 90–100 miljoner SEK. Stödet är del av Sveriges mediestödssystem för att främja mångfald och har minskat något under övergången till det nya systemet (nu runt 13 miljoner per år i senare beslut). ETC har tidigare fått återbetalningskrav för felaktigt utbetalt stöd (2018), men har fortsatt motta stöd. Källa: Mediemyndigheten och rapporterade beslut.

Claude Security is now in public beta for Claude Enterprise customers. Claude scans your codebase for vulnerabilities, validates each finding to cut false positives, and suggests patches you can review and approve.

Worst hire I made cost me €38k and 5 months. Not a bad interview. A bad brief. I started hiring before I knew what I actually needed. I built a doc that fixes this. Give it to your recruiter and half the work is done. Like + comment "HIRE" and I'll send it over.

I'm giving away the Claude Code skills we use to manage $300k/mo in ad spend at ColdIQ. 4X ROAS on $1M+ spent. Ivan, our head of growth, built them off 300+ hours running ad campaigns for our clients. They run Google, Meta, and LinkedIn ads from the terminal in plain English: → bulk edits across platforms → custom audiences from CRM lists → creative fatigue detection before CTR dips → bid adjustments at scale → performance audits across periods Reply "ads" and I'll send the full repo. Must be following.

3 months ago I started building a coding agent that runs in the cloud. It's since written every line of code I've shipped, including itself. Today, I'm open sourcing it. Introducing Open Agents.

@nateparrott Holy!! In theory could this be pushed to the actual repo for the changes or what flow do you recommend to make it reality on production?🙏🏼

What I love about designing with code is that you can do so much more beyond static mocks. Here’s a prototype using voice + video input to comment on a doc. It’s fun! Our goal is to give designers the power of code plus the ease and control of other tools.

@FredrikHjelm4 That sounds really cool! I am claude pilled right now (with just some codex for reviewing and validating specs) and switching between 3 max subs for now - works - but always looking for inspiration!!

@martinxjonsson Depends on the work For more advanced reasoning work, performance is the main thing we optimize for For more monotonous rep work, the frontier models are really not needed You?

One year ago: one dev, one task. Today: one dev, ten parallel agents across the codebase. We built a cockpit to run 10 versions of our repo simultaneously. Heavy planning mode first, then agents fan out, each working different tasks on short and long horizons. Code review agents in the loop. Default actions pre-built for when an agent wraps. The bottleneck is no longer writing code. It's taste and expertise. Welcome to the superleverage era.

@FredrikHjelm4 Alright! Do you usually run through sort of a 'model-pipeline' based on the task or does it always go based on cost first?
