I love refactoring

Computer science: The halting problem is unsolvable Software engineering: If it doesn’t resolve in 30 seconds, I don’t need it

Computer science: The halting problem is unsolvable Software engineering: If the program takes more than 30 seconds, I don’t need the result

So I was gonna try an epic Waymo journey to Sunnyvale today, then I noticed the time. Almost 3 hours 😂 Guess we’re not quite there yet thanks for the warning

Short run today. The mind is willing but the flesh is flabby and bruised

Oh hell yeah, a Slovenian won the Dakar! amazing

Here's how to navigate a tough job market from someone dumb enough to have done it before. Me. swizec.com/blog/a-tough...

Nothing feels better than recent hires saying “I’ve never seen engineering move this fast”

LLMs are pushing us back towards Not Invented Here syndrome. Why pay a vendor for 2 features you need and 10 you don't? It's easy to build yourself ironically this means we'll need *more* software engineers, not less all this stuff gotta stay maintained

I think for many programmers, coding agents are their first experience of working on an actual team. it's kinda beautiful to watch people discover collaboration, basic project management, writing specs, etc

My biggest career miss was saying No to Shopify two years before IPO. Back when Tobi was still the last interview. That was cool. But you can't win every bet Your goal is to be a little more right than wrong and keep playing. Long-term it all works out swizec.com/blog/place-g...

wow v0 built a whole system to collect testimonials took a little iteration but pretty sweet. I can finally “code” from my iPad while watching TV

Here's the best part of transitioning to eng management It is 4:51pm. I finally have time to start coding. But it's an urgent prod issue that we didn't plan for 🙃

unironically starting to think about my Leave Now criteria when you have official accounts quoting Ein Volk, Ein ... that is not a good sign

someone asked if I’d ever cofound a startup [again]

The best engineering books feel like I should’ve read them 10 years ago, but 10 tats ago I’d think they’re dumb

🇸🇮💪

Minutes of planning save you days of programming. It is shocking how little planning it takes to make a big difference. swizec.com/blog/small-p...

Late Christmas present: my copy of Scaling Fast by @swizec.com just got delivered. 📦

honestly comments like this make sweating over a book for 3 years feel worth it

❤️

some logitech server went down so now my mouse dont work right 🙃

Your biggest impact usually comes from work you find so easy it's not worth mentioning, but others think is hard

What's the problem with end-to-end tests? They're flaky to run and annoying to write. But they're the best way to actually test your app. I may have a solution: An agentic approach. Been thinking about this for 3 years v0.1.0 up npm 👇 please try swizec.com/blog/a-bette...

Like running through soup today. Then it rained and it was like running through a waterfall

should’ve bet on polymarket

Some thoughts on life, the industry, and making bets with your career. I called it a year in review but it's so much more swizec.com/blog/2025-ye...

engineers with good taste will dominate

I am jetlagged and couldn't sleep so check out my experimental E2E testing agent verify a whole purchase flow from a 2 sentence description this is gonna be huge 🤩

screw tokens check this

I’m going to be the old man (41) who talks about understanding the code the AI generates and being able to write it by hand. The kids will say I’m out of date, and I’ll never be sure they’re wrong. The indignity will never be lost on me that I’m talking about hand-writing god damn Javascript.

The key to 10x results is to remove 9x of the work ~ @swizec.com swizec.com/blog/how-goo...

Here's a more complex example - describe your test - agent tries to make it happen on your website (50sec) - writes down steps as playwright script - future runs replay the script and verify website works (10sec) I'm excited. This will save so much tedium

Ok it's a little slow but this feels like a good way to write e2e tests. Just needs a good caching layer video sped up 5x

my dudes, it is gorgeous here. I could winter in almost-the-french-riviera ever year but only here for 3 days

I finally tried the famous provance chichi. She’s been telling me about this delicious treat for 10 years. It’s even better than she said

Fantastic weather in Sanary sur mer

best cheesecake recipe you’re welcome

IT WORKED! The agent can follow a simple instruction and test a workflow \o/ now just gotta keep track of the playwright calls and output a test suite

As we enter the funny week-without-time between Christmas and New Year, it's a great time to reflect – Are you playing games you want to win? swizec.com/blog/are-you...

I GOT TO RIDE IN A URAL TODAY!!

South of France is super nice. Even the wind feels warm
