We ran a randomized controlled trial to see how much AI coding tools speed up experienced open-source developers.
The results surprised us: Developers thought they were 20% faster with AI tools, but they were actually 19% slower when they had access to AI than when they didn't.

The notion of "relentless refactoring" is an essential part of programming. It's integral--something you do all day, every day, as you work.

Scale AI’s CEO states DeepSeek rivals or matches the top AI models from American companies. Trained for just $6M (10-100x cheaper than big tech models), it runs on older chips due to chip bans and is open source.
This is a paradigm shift and makes $500B spend on Project Stargate feel misguided.

Scale AI CEO says China has quickly caught the U.S. with the DeepSeek open-source model
Alexandr Wang, CEO of Scale AI, said Thursday that the AI race between the U.S. and China is an "AI war."

Love that a lab with a fraction of the GPU power, budget and staff of the big American AI whales has dethroned them and then open sourced their trained model and documented all their secret sauces.
Without any of the bullshit of “we can’t open it, it would become sentient and turn against us”

Layoffs have been going on for years in big tech but it’s still somewhat shocking to see my former employer laying off people with 20+ years of experience at the company as part of performance based cuts with no severance.
This post on Blind is similar to many I’ve seen on LinkedIn & Facebook.

I did the podcast thing! It was great fun chatting with Matthias Endler on his “Rust in Production” podcast. We talked about our little Rust based ECU at Volvo Cars and how it came about. Check it out: corrode.dev/podcast/s03e...
Volvo with Julius Gustavsson - Rust in Production Podcast | corrode Rust Consulting
The car industry is not known for its rapid adoption of new technologies.
Therefore, it’s even more exciting to see a company like Volvo Cars embracing Rust for core components of their software stack...

Also, it’s best if the entire team works on one story at a time, moving to the next on one when the current one is done and released to customers. “Little’s Law” tells us that the more things you work on simultaneously, the slower the work will happen.

People in the Scrum camp sometimes panic when they can’t finish a story within the Sprint, which they classify as a failure. That’s not actually how it works.

I hope we come up with better standards to protect the kids after this. This is a big one!
PowerSchool provides cloud-based software to some 16,000 K–12 schools worldwide serving 60 million students—which means the potential scale of this network intrusion could be massive.
Data breach hitting PowerSchool looks very, very bad
Schools are now notifying families their data has been stolen.

An absolute must-read from @mipsytipsy.bsky.social, with the single most important piece of founder wisdom that you will ever hear (and most will forget/ignore/be talked out of): "You should ALWAYS have as few employees as possible. Always."
I (finally) wrote up my thoughts on "Founder Mode" and the Brian Chesky morality tale about how he turned around Airbnb company culture.
This has made it into the Silicon Valley water table; it must be dealt with. There are some good nuggets within; let's dig them out.

Unless the code we changed runs in production, we haven't done nothing. Works on my computer means nothing. Works in QA/Staging/UAT environments also means nothing. Production is the only arbiter.

My experience is that the major obstacle in practicing TDD is our innate propensity to overbid on work and go for the big batches. The only way to do TDD properly is to learn how to work in tiny batches.

I'm ready to bet my money that adding a gate that delays the time it takes for a change to reach customers is making things worse than otherwise.
But, it will take time for our industry to realize that because:

If you really care about productivity, why aren't you examining the value of mandatory code review? I know this is my least popular take, but it remains unclear to me that it improves quality commensurate to cost, and it's the most unquestioned shibboleth in tech today
