Indeed, that is my mistake. I misread the denominator of the consumption figure. Luckily the orders of magnitude are so dissimilar that mere factors of 100x do not affect the calculation. 3-4 acre*foot per year per acre of almonds results i

Why? It is only a measly 500,000 gallons a day. That is only ~2,000 m^3/day (~2 acre*foot/day). Even if they exclusively used the most expensive source of water, seawater desalination, that would only be ~800 $/day. Your aver

Thank you for your response. I retract my concerns. The protocol seems adequately performant with the new information you have provided. The benchmark is clearly artificially bottlenecking on (non-disclosed by the vendor) I/O limits an

Is it actually high performance? Looking at their transport protocol benchmarks on AWS [1][2], they average ~3 million 288-byte messages per second on c5.9xlarge (36 vCPU) instances. When increasing to their MTU limit of 1,344 bytes per mes

Well the problem there is companies who are too stupid to invest in cheap tooling with massive ROI for their developers. A pretty constant problem in software development. And I am not knocking JTAG over USB. It is certainly convenient and

Most of those boards have a separate physical JTAG connector (at least in development kits, this article indicates JTAG over USB is disabled in production systems anyways so no difference there) which is what they are expecting you to use f

You are right about the data. The data is unfortunately submitted by individuals who are such overwhelming fans of Tesla FSD that they are willing to voluntarily submit after-action reports and is thus extremely biased towards Tesla and sho

You can also go with what it is telling you. The car breaks the law by illegally parking in a clearly marked fire lane. They can not even stage a carefully curated demo without committing a clear crime on video.

Why is that interesting? Do you expect them to get into a crash in a simple 15 mile journey? Humans go around 1,000,000 miles between crashes. You literally need to make such a journey over 50,000 times in a row without a crash to be a actu

I liked the part where it illegally parked in a clearly marked fire lane. They can not even stage a carefully curated demo without committing a clear crime on video.

Yep, until they make a legally binding claim supported by a self-imposed liquidated damages clause for failure to abide by their own claims their claims should be ignored.

It is funny you should say that binocular vision is sufficient when Tesla Vision hardware does not have binocular vision. HW3 has three front-facing cameras that are not only too close together to provide binocular vision with adequate disp

Tesla only let their greatest, most breathless, biased supporters try and "review" their supervised driving pilot. That was Farzad [1], a long-time prolific promoter. Given that their livelihood is on the line, it is not at all su

Well we have QUIC now which layers over UDP and is functionally strictly superior to SCTP as SCTP still suffered from head-of-line blocking due to bad acknowledgement design.

MMU hardware has a hardware-defined minimum mapping granularity (i.e. page size). On x86-64 this is 4KB. On ARMv8/v9 the specification allows runtime configuration for any of 4KB, 16KB, or 64KB as the minimum mapping granularity on a p

FSD, in particular, already did definitively kill a person between 2022-08 and 2023-08 [1]. Still going strong. Note that this is distinct from the tens of publicly documented fatalities on Tesla Autopilot. [1] https://static.nht

That is entirely untrue. Fred Lambert was one of the most full-throated supporters of Tesla just a few years ago. He personally referred around 15 million dollars of sales [1] to Tesla. If even Tesla's most fervent supporters now call

Ah yes, the classic Tesla promoter smear. Somehow operating systems and software development tools are in direct competition with Tesla ADAS software. Turns out Tesla is not in competition with GM, it is actually in competition with Linux,

It appears to just treat school bus stop signs as regular stop signs. So, it will most likely only do a brief stop if the stop sign is in its lane. Otherwise it will not stop at all.

There is a school bus with stop signs out and lights flashing. You are legally required to stop until they are retracted. That law exists for the express purpose of giving drivers ample time and opportunity to stop in a situation where scho

You get a memory bound on GPUs because they have so much more compute per memory. The H100 has 144 SMs driving 4x32 threads per clock. That is 18,432 threads demanding memory. Now to be fair, that is separated into 8 clusters which I assume

I am not sure that is the case anymore. High Bandwidth Memory (HBM) [1] as used on modern ML training GPUs has immensely more memory bandwidth than traditional CPU systems. DDR5 [2] tops out around 60-80 GB/s. HBM3, used on the H100 GP

You know that is a nonsensical request. Why would a Linux LPE result in a guest to host escape? That is like asking for the last 3 iMessage RCEs that that could be directly used to get a kernel compromise. You obviously leverage the RCE to

VM sandbox escape is just "perform a hypercall/trap to pass specially crafted data to the hypervisor and trigger a hypervisor bug". For virtual machines, the hypervisor is the privileged host and now the host is compromised.
