@elonmusk @boringcompany @grok is it cheaper/easier to build hyperloop than the equivalent of Shinkansen/European high speed railway ?

The best way to pace the frontier is to hold the labs fully liable for the behavior of their models.

I see people comparing the odds of a nuclear armageddon with AI killing all humans, but I can’t think of a method other than a nuclear armageddon that AI can use to successfully kill all of humanity

RT to help Simon raise awareness of prompt injection attacks in LLMs.

Feels a bit like the wild west of early computing, with computer viruses (now = malicious prompts hiding in web data/tools), and not well developed defenses (antivirus, or a lot more developed kernel/user space security paradigm where e.g. an agent is given very specific action types instead of the ability to run arbitrary bash scripts).

Conflicted because I want to be an early adopter of LLM agents in my personal computing but the wild west of possibility is holding me back.

Reliance’s Jamnagar Refinery is an engineering marvel

It is the World's most complex and largest integrated, single-site refinery

It was the largest industrial investment made by an Indian enterprise at a single location

Some amazing facts on this Refinery -

Guy on WallStreetBets has $1M+ in trading losses this year and is looking to marry someone with $1M+ in capital gains…

They will offset and split the savings.

I love this country.

Introducing Willow, our new state-of-the-art quantum computing chip with a breakthrough that can reduce errors exponentially as we scale up using more qubits, cracking a 30-year challenge in the field. In benchmark tests, Willow solved a standard computation in <5 mins that would take a leading supercomputer over 10^25 years, far beyond the age of the universe(!).

I have realised telecom security is a joke and you are much better off using an authenticator app or yubikey anyway. Almost all of banking in India uses SMS OTPs for 2FA which now scares me.

What happens if your CPU gets something wrong? If it wakes up one day and decides 2+2=5?

Well, most of us will never have to worry about that. But if you work at a company the size of Google, you do, which is why this paper on "mercurial cores" is so fascinating.

What the authors report--and supposedly this is common knowledge at the hyperscalers--is that a couple cores per several thousand machines are "mercurial." Due to subtle manufacturing defects or old age, they give wrong answers for certain instructions. These can cause all sorts of impossible-to-diagnose issues. Some rare problems at Google that were traced back to bad CPUs include:

- Mutexes not working, causing application crashes
- Silent data corruption
- Garbage collectors targeting live memory, causing application crashes
- Kernel state corruption causing kernel panics

What makes CPUs go bad? It's very hard to tell. The authors posit that issues are becoming more frequent as CPUs get more complex, but there aren't solid numbers behind that. There are certainly strong relationships between frequency, temperature, voltage, and bad CPU behavior--most mercurial CPUs only cause problems under very specific conditions, but those conditions vary from CPU to CPU. Age is another source of problems, as older CPUs are more likely to exhibit problems.

Bad CPUs are an especially serious problem because they're very hard to detect. If cosmic rays flip bits in storage or on the network, that can be detected through error coding. But there's no analogy for a CPU that allows cheap online verification of its correctness. Instead, the best detection techniques involve monitoring for symptoms. If a core exhibits exceptionally high rates of process crashes or kernel panics relative to its fellows, that's a strong indication something is wrong with it. For the most critical applications, the authors propose triple modular redundancy--redoing each of its computations on three cores and majority-voting a reliable result.

More than anything, this paper is a call to action--letting everyone know that CPUs can fail. So now, if you ever find a bug you can't diagnose, you can blame the CPU! 🙂

I’ve started working with go now. So far no strong opinions. I have found the toolchain to be a bit fiddly. Especially, the UX for working with several projects using different versions of the language is horrible.
