Minimal here is really confusing me: why a phone with so many physical buttons/keys and jack port is minimal but other phones without are non-minimal?

isn't any ipv6+ supposed to use any string address and no DNS is required at all? :D

I am always wondering how those backdoors are discovered without internal leaks, fuzzing or enumerating all instructions bytes seem like too random.

I guess very soon we will see on HN that lots of young folks will be excited )share their findings of some “brilliant” and “innovative” ways to save memory.

So a so-called vulnerability has:

- cited code not exist, and

- PoC not work.

How would any serious system allow it become a big deal?

You probably need to mention the term otherwise people would definitely downvote. Shorting those companies in the long run is almost always a bad idea.

5 trillion IPO of three companies this year! They still need real money to buy the offered stocks, I am wondering which markets will be sold in order for investors to get the cash.

I wish people'd report metrics like "transactions per second, 99.x% availability with N secs/mins p99 latency, ..." when describing how practically useful and how effective a real-world banking/transaction system is, which further proves the practicality of the programming language.

> We serve over 300,000 businesses. We processed $248 billion in transaction volume in 2025 on $650 million in annualized revenue

> The system we've built has worked well for years, through hypergrowth, through the SVB crisis that sent $2 billion in new deposits our way in five day.

This is a strange way to describe a transaction processing system with total amount of money it processed. The reliability or scalability is not measured as O(n) dollars. In theory, $248bln or $2bln can be done in one transaction although I know it is not the case in reality. It would be impressive to see the typical system design properties like transactions per second, latency distribution, etc.

It’s less about 'old vs. new' and more about the evolving trade-offs dictated by the constraints of the era. There have always been engineers trying to squeeze every last drop of performance out of the bits available to them.

The blog is new but the paper was submitted almost one year ago: https://arxiv.org/abs/2504.19874. Anyone has ideas if this is already implemented in many models (at least Gemini, I guess)? If that's the case, can I expect cheaper RAM for my computer :D

In SF bay area, there are always gas cars trying to show off their horsepower especially during rush hours, no matter how slow the traffic is. That noise is more annoying than tires.

> Palantir's secret weapon is the closeness and affinity to the DoD.

Is it a secret? I got an impression that it has been well known. How could you get any big number contracts without former secretaries or retired generals in your board or in your ‘consulting’ team?

Oh I am more than happy to tell people how I took down entire Google Cloud 11 years ago. I mean, of course to the level of details Google is comfortable with to share externally :)
