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

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

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.

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 :)

No, sorry, I wouldn't buy EVs from any US company any more until they are matura enough that the model production surpasses at least Tesla Model S+X since released. Their reliability just suck. I don't want to waste my life again

Making 20 y/o CPU with today's process? It is cool but yeah not really a wise business decision.

Oh running Linux on a MCU without MMU. I feel there is a gap between MCU and modern CPU, and also between the software running on top of them. The missing piece is a mid-size computer with: - A processor, single or multi-core, with computin

My experience: customers with $$$ will always believe they are very important, so important that losing a single bit is the end of world. So you may not want to convince customers waving huge $$$ checks that their data are not that importan

Does their status page depend on something that is down already, so the page just fails static now hence no new updates?

This feels like the 80s/90s when people hacking assembly or finding undocumented instructions to squeeze CPU for performance. Until one day either the compiler will be highly optimized enough or the GPU will be so powerful that such tr

I don’t understand why this is not obvious to many people: tech and stock trading are totally two different things, why on earth a tech expert is expected to know trading at all? Imagining how ridiculous it would be if a computer science gr

Good to see such bare metal work in HN, I feel there has been fewer this type of work nowadays. Back to the OS architecture, AFAIK, exokernel tries to get rid of the OS overhead (context switching, abstractions, etc.) to improve performance
