Goodness. The ArrowJS sandbox lets you build amazing stuff.
Here's an infinite "app canvas". Drag a new box, scribble what kind of app you want, and it renders it for you.
no pre-defined components
no pre-defined styles
no iframes

Last quarter I rolled out Microsoft Copilot to 4,000 employees.
$30 per seat per month.
$1.4 million annually.
I called it "digital transformation."
The board loved that phrase.
They approved it in eleven minutes.
No one asked what it would actually do.
Including me.
I told everyone it would "10x productivity."
That's not a real number.
But it sounds like one.
HR asked how we'd measure the 10x.
I said we'd "leverage analytics dashboards."
They stopped asking.
Three months later I checked the usage reports.
47 people had opened it.
12 had used it more than once.
One of them was me.
I used it to summarize an email I could have read in 30 seconds.
It took 45 seconds.
Plus the time it took to fix the hallucinations.
But I called it a "pilot success."
Success means the pilot didn't visibly fail.
The CFO asked about ROI.
I showed him a graph.
The graph went up and to the right.
It measured "AI enablement."
I made that metric up.
He nodded approvingly.
We're "AI-enabled" now.
I don't know what that means.
But it's in our investor deck.
A senior developer asked why we didn't use Claude or ChatGPT.
I said we needed "enterprise-grade security."
He asked what that meant.
I said "compliance."
He asked which compliance.
I said "all of them."
He looked skeptical.
I scheduled him for a "career development conversation."
He stopped asking questions.
Microsoft sent a case study team.
They wanted to feature us as a success story.
I told them we "saved 40,000 hours."
I calculated that number by multiplying employees by a number I made up.
They didn't verify it.
They never do.
Now we're on Microsoft's website.
"Global enterprise achieves 40,000 hours of productivity gains with Copilot."
The CEO shared it on LinkedIn.
He got 3,000 likes.
He's never used Copilot.
None of the executives have.
We have an exemption.
"Strategic focus requires minimal digital distraction."
I wrote that policy.
The licenses renew next month.
I'm requesting an expansion.
5,000 more seats.
We haven't used the first 4,000.
But this time we'll "drive adoption."
Adoption means mandatory training.
Training means a 45-minute webinar no one watches.
But completion will be tracked.
Completion is a metric.
Metrics go in dashboards.
Dashboards go in board presentations.
Board presentations get me promoted.
I'll be SVP by Q3.
I still don't know what Copilot does.
But I know what it's for.
It's for showing we're "investing in AI."
Investment means spending.
Spending means commitment.
Commitment means we're serious about the future.
The future is whatever I say it is.
As long as the graph goes up and to the right.

A behind the scenes look at the making of the 1989 video game "Prince of Persia". Designer Jordan Mechner used rotoscoping to animate the movements of the game's characters, tracing video footage of his younger brother running and jumping (as well as video from old Errol Flynn films).
Loving the new Flow2 from @lofreeco The silent variant is silent enough for the office while still being a joy to type on.

💙 New blog post!
I set out to announce two web components I put together for displaying 🦋 Bluesky likes and ended up ranting about how painful it is to build accessible, localizable web components in 2025.
The components are still there, though — lucky you?

LLMs hallucinate 100% of the time. They just happen to hallucinate the right sequence of words ~80% of the time.

i can't explain how insane this is. I'm a programmer with no doctor experience at all and in 5 days I've become a fully functioning doctor for my friends, family and community with the ability to make patients weight for 30+ min past their scheduled appointment time, listen to them for 2 min then ask chat gpt whats wrong and get a diagnosis, give them a prescription and send them on their way. All with beautifully high invoices that will earn me thousands
this would've take me 8+ years of schooling, so far its cost me $25 a month.
I literally cannot believe it.

We recreated @MarkRober's recent "Looney Tunes" test, to see whether @Tesla Full Self-Driving and Enhanced Autopilot would stop for a fake wall.
Rober was right. Enhanced Autopilot on Hardware 4 fails to detect the wall.
v12.6.4 on Hardware 3 blows straight through the wall. Only v13.2.8 on Hardware 4 stops for it.
@ElonMusk promised over 3 million people who bought a Hardware 3 car that it had all the hardware they needed for Full Self-Driving. He promised all they needed was a software update.
Elon promised that Hardware 3 robotaxis would make their owners $30,000 a year.
He promised that Hardware 3 Teslas would appreciate in value to $200,000.
That adds up to between $700 billion and $1 trillion.
Hardware 3 Tesla owners were defrauded by Master Scammer Musk.
Have people used @cursor_ai or @windsurf_ai to build / vibe code a web app that is not based on React or Next.js?

🤯 BREAKING: Manus AI created its own open-source alternative. In 25 min, it built a complete AI agent system from scratch!
ANUS (Autonomous Networked Utility System)—@eugeneshilow's brilliant idea
Why pay $20K for invites when it can be free?

WD-40 was created for American Space Launch, specifically it enabled America’s first ICBM / Nuclear Missile
Invented by a small startup in San Diego in 1953. The name stands for “Water Displacement, 40th attempt”
Here’s the fascinating story:

99% of financial advice is terrible.
Millionaires get rich because they know what to ignore. My net worth increased 6-figures *per year* once I ignored terrible advice.
Here are 17 of the worst pieces of advice you must ignore to get rich.

"How do you future-proof your software engineering career?"
The best engineers have always been more than just coders. They've been problem solvers who understand both technical constraints and human needs. As AI reduces the friction of implementation, a holistic understanding becomes even more valuable.

Another way to look at AI:
New devs will not learn how to code fluently. So when shit does eventually hit the fan and AI can't correct it, my value as a dev who is fluent, will only go up.

Remember when one usage of is-number caused 440GB/week of traffic to npm? Well the only reason people where using it was because the popular chokidar file watcher did indirectly.
chokidar v4 just dropped it and others resulting in a savings of 2.5 TB/week of traffic to npm
lol, removing is-number from this package saves 440gb weekly
