Can you point to a study showing that Neuralink has achieved any of those things you mentioned? What evidence is there that the implants have reduced scar tissue formation and what supports the assertion that they would be usable for years?

Why would this be remembered as a breakthrough? Playing games with a BCI is many years old at this point. Here is an article from 2020 talking about playing Sonic the Hedgehog, amongst other games [1]. Here he is fist bumping President Oba

No. I am pointing out how being unable to communicate makes it very hard to determine intelligence. It is hard to determine if another human is smart without being able to speak the same language or explain the procedure and contents of t

Certainly. Once you have a deterministic environment, the ability to replay execution is basically free. In fact, what has been described is basically the replay engine in a record-replay system which “runs” the recorded execution of a non-

There is a pretty profound communication gap that you seem to be discounting. A closer analogy might be trying to teach a 7 year old who speaks a different language. Or even deeper, a 7 year old child who only knows sign language and you do

The product does not appear to be a record-replay debugging product, it appears to be a precise fault injection test generation product. In a record-replay debugging product, you want to reproduce the execution of your system to translate w

Musk was wrong. He said specifically and unequivocally that Tesla would be delivering fully autonomous vehicles to customers within a year, every year for the last 8 years. Just to get ahead of anybody claiming it was not a firm promise, in

“Driving” is not solved unless you mean perfectly paved streets in perfect weather on empty streets with no pedestrians. A competent solution like Waymo can handle significantly more complex cases at real world levels of complexity, but it

The Common Criteria is broadly and comprehensively used and covers most major product categories. There is no product security standard more widely used and internationally accepted and most major vendors already certify against it. It is

We already have that. It is the Common Criteria for Information Technology Security Evaluation, ISO 15408. Most large software developers already certify products against it such as Windows [1], iOS [2], Android, Linux, etc. It is the prima

If they had to back it up then they would not be able to say it. Are you really trying to infringe on their rights to endanger lives by fraudulently claiming suitability for safety-critical applications without any evidence beyond their ima

The concept of ordering is independent of architecture. What operations need to be ordered relative to other operations to be correct does not change. But, your architecture may implicitly guarantee certain orderings so you do not need to e

The paper seems to make no mention of the memory barriers in play, merely talking about the atomic operation and the conditional branch. Despite that, they indicate they produced a proof-of-concept exploit leaking data. Traditionally, you w

I hope they eventually add a extension to support configurable bounds on allowed fragmentation. There is not really a good way to create a non-allocating fixed upper-bound memory implementation in the presence of worst-case fragmentation ex

I was talking about execution tracing , specifically, not tracing as a general concept. Tracing as a general concept just means a non-sampled time-series event stream and as commonly used these days generally also includes "stacking

You are directly using the CPU, you just do not have full access to the entire CPU. There is no userspace ALU that your numbers get crunched on, there is no userspace register file your working set is stored in (actually, they might do that

The usage of the term execution trace really threw me off. I am more familiar with that term meaning a instruction execution trace or maybe just a function trace, so it made no sense why stack unwinding would be a bottleneck. Turns out it i

In your first comment you said metric year, month, day. So it was unclear since a year and day are inherently solar concepts. It would have been clear if you just went straight to kiloseconds or similar. You also did not include the Sun in

Unless you are suggesting removing the solar day and solar year, you fundamentally have a little over 365 Earth axis rotations per Earth orbits. Attempting to build decimal parts fundamentally results in ~36.5 deci-days. Assuming we extract

You do realize the FBI is a law enforcement agency, right? It is so commonplace and expected that they have literally issued press releases where they publicly claim to have hacked criminal networks [1]. For that matter, who do you think hi

Offense is easy because defense is a joke. Nobody in the entire world has network connected commercial IT systems that are even minimally adequate. Yes, that includes Google, Amazon, Crowdstrike, any bank, Microsoft, Apple, Mandiant, and wh

Exploit development is more about effort and focus than difficulty. Any halfway-competent team can completely compromise any commercial IT security system. It is a competition to see who can crack the most eggs. Anybody can do it, but the w

Critical exploits make it into the wild all the time. At worst they cause a tiny, temporary dip in stock price and frequently they cause the stock price to go up long term due to publicity. That is why they only spend 10 M$ on bounties, the

I did not present proof. They asked what it would mean and a consequence of physical laws not being time invariant would be that energy does not need to be conserved. To the extent that relates to epistemology that would be more like anti-p

by Veserv 3y ago
Well for one, if the laws of physics are not time invariant (i.e. the laws of physics are not the same at all points in time) then energy can be created or destroyed [1]. So that would be quite a shocker. [1] https://en.m.wikiped

CPU bugs are extremely rare compared to software bugs. Like, millions to billions of times less likely. CPU bugs are news, software bugs are Tuesday. You might as well argue that a steel box protects its contents no better than a cardboard

Machine code running in unprivileged mode with no shared memory and where syscalls auto-fail can do nothing malicious. Such a system is even more locked down than a Java program (when it does not also rely on hardware isolation) with no acc

Obviously, as I made no mention of specific performance in the event of breach of contract the remedy for failure to meet contractual obligations would be damages. The question is: What level of durability does AWS contractually guarantee w

I read that page and it does not provide any contractual durability guarantees as far as I can see. It provides "designed for availability" and then contractual availability SLA guarantees. It provides "designed for durabilit

Machine code does not require granting anything. The presence of a shared filesystem is a artifact of the OS, not any sort of inherent requirement. The actual effect of machine code being opaque is actually "beneficial" to securit
