Ah yes, the bizarro world where systems are normally unhackable so the default assumption is impenetrable security and you need to prove they are insecure. Thank god this is not the world where things get hacked all the time and where any c

I engineer and design network device drivers and network protocol stacks. NAT is a terrible network protocol. The correct protocol would have been a DHCP extension giving you a 49-bit address where your IPv4 address constitutes a /32 w

1. IPv6 does have NAT [1], NAT66. 2. NAT is totally orthogonal to IP and addressing. 3. NAT (as in transparent packet modification to rewrite addresses) is utterly idiotic. Ephemeral, anonymous address allocation with inbound filtering is s

High bandwidth memory (HBM) can deliver TB/s of memory bandwidth and has completely shattered the memory wall for individual cores/compute elements. The only way for compute to keep up is going wide and parallel as seen in GPUs. D

"Improved" is a useless word. Is their security now adequate? Is it secure against the run-of-the-mill financially motivated threat actors we see regularly and orchestrating thousands of profitable attacks annually? We regularly s

You can still do better by not doing any TSC to nanosecond conversion. Instead, you inject clock adjustments into your log stream allowing you to convert when you decode the logs rather than when you generate the logs. Using the final versi

You are totally right. In accordance with the Tesla Referral Program contract a estimated ~250,000,000 $ in sales were referred to Tesla by major referrers earning those major referrers ~80 free Tesla Roadsters [1], announced as a 250,000 $

I find it funny how stealing 500,000 $ from a fan is a "debacle". In most places that would be considered a felony instead of a justification to smear the victim and call them a whiner.

Their lawyers already did that and got it ruled that Tesla’s statements are unbelievable lies and thus Tesla is not liable for deceiving customers or the public. https://law.justia.com/cases/federal/district-courts

That does not work. They just infect you and do not demand a ransom for a few months as they encrypt all your data going to the backup. Now your backups are also encrypted going back multiple months and you have to discard months of work.

What is the point of making up claims of "extreme" performance without any accompanying benchmarks or comparisons? It really should be shameful to use unqualified adjectives in headline claims without also providing the supporting

There are plenty of ways for language to be better now that we know far more about arithmetic than when number words were created. "One Five Five Two Three One" is 6 words, 6 syllables long where as "One Hundred and Thirty Tw

You should actually not use format-swapping operations. You should actually use format-swapping loads/stores (i.e deserialization/serialization). This is because your computer can not compute on values of non-native endianness. As

I have frequently proposed a objective legal standard for false advertising that handles that: "Technically, your honor". If somebody says that in court, they lose. The words they used, as commonly understood by the target audienc

When did we enter the twilight zone where bug trackers are consistently empty? The limiting factor of bug reduction is remediation, not discovery. Even developer smoke testing usually surfaces bugs at a rate far faster than they can be fixe

I am glad that you agree that their legal department’s explicit and intentional exclusion of known successful non-mercenary attacks is precise and legally sound. It is advisable to not grasp at straws to think up ways that highly paid lawye

They have a legal department carefully directing what they say. In a court of law, their lawyers will successfully argue that they are beholden to only the precise letter of their statement. Are you arguing that their lawyers are incompeten

Oh geez. Legal did not give them the go ahead to make the unqualified statement: “We are not aware of any successful spyware attacks” they had to explicitly qualify it with “mercenary”.

The argument is literally that it is problematic to send 100 k$ interceptors to stop 1 k$ drones and then you turn about and argue you can end 100 k$ cruise missiles to stop 1 k$ turrets. Your argument is inconsistent with the entire premis

> Then two drones approach from opposite sides at 200 MPH. A drone that can go 300 km/h is way more than 100 $, you are in the thousands of dollar range at that point. Turret wins if it blows up one. Also, it could probably blow up

Automatic turret-mounted anti-air shotguns. Blow up 100 $ drones for the cost of a 0.50 $ shotgun shell. I bet you could do aiming and firing in less than 0.1 seconds with nearly 100% accuracy in the 50 meter range which would enable ~10 de

The code described is not nested interrupt handlers. It is eBPF code executing during a context switch which is interrupted by the sampling NMI which is also configured to execute eBPF code. NMIs will not nest, so there is no risk of arbitr

Just to elaborate: Tesla’s actually have zero binocular vision coverage because the cameras have different focal lengths and are too close even if they did have the same focal lengths. They are also below minimum vision requirements for dri

Geez, your company really needs to not be writing code in interrupt context until you learn how it works. bpf_ringbuf_reserve() is perfectly fine to call from interrupt context. The problem is that you are manipulating the same data struc

How is this a kernel issue? The code that deadlocked was entirely written by Superluminal who grabbed a shared lock from a interrupt handler. Not doing that is literally the very first lesson of writing interrupt handlers and if you do not

It is amazing that you can complain about a simplified example and then both misunderstand it and get literally every single one of your "corrections" wrong. 1. As I made abundantly clear, 20% is the passive ownership of the index

To explain the mechanism simply. Suppose you had a index of 100 companys each with a market cap of 1 G$ for a total of 100 G$. You have passive investors owning 20 G$ of that index, amounting to 20% of the total, 20% of each company, and 20
