I mean this is not actually true and the statement justifies and vindicates those that do sell out by saying of course anyone would. There are countless marytr for religion, politics, and other things.
A better way is to say you can always find a cheap sellout at least than the morally dammed cannot claim equality of belief
You mean like all of the religious leaders who are actively supporting a defending a three time married adulterer? You’ll have to excuse my skepticism of the morality of “the moral majority”.
While Dario is not my hero with the sometimes the outrageous things he says he has a firm moral compass and a backbone that aligns with mine and thus I will support his company and their products in my personal use and my work.
Way more safety and rigid testing procedures and a better understanding - the Apollo program was all done by the seat of the pants engineering that somehow worked all based on the ideas of the team that built the German V2.
Each F1 rocket engine was hand tuned by drilling holes into the "plate" so it would not cause the combustion mixture to vibrate the engine into smithereens.
Such an approach would never be tolerated today by NASA.
This complete nonsense. The Apollo team was much, much, much, much larger then any V2 team. And mostly Americans.
And their testing procedures were actually very high quality. You don't just accidentally land on the moon and return. That doesn't just happen 'somehow'. That is truly idiotic level analysis.
> Each F1 rocket engine was hand tuned by drilling holes into the "plate" so it would not cause the combustion mixture to vibrate the engine into smithereens.
And that this works was established with lots of both experimental testing and lots of theoretical work.
So much so that F1 is one of the most reliable engines ever used in space flight history.
> Such an approach would never be tolerated today by NASA.
Except of course that the RS-25 engine used by NASA today is known to be less safe then F-1. Having had more failures and generally causing more minor operational problems.
It seems you have absolutely no clue what you are talking about. In fact, NASA own analysis before they were forced to pick SLS by congress indicated that a updated version of F-1 (still relying on the analysis of those people in the 1960s) would be a much better rocket.
Apollo worked because engineers from the top to the bottom made smart engineering focused decisions taking responsibility for their part of the stack, and close working together in teams on a shared goal while having very solid testing procedures for everything.
They are using M workstation class chips for inference on their own blades since Google's models are meant run on TPU's it would not have been difficult to port it.
They also use Anthropic internally (code/marketing/sales) which runs their models on Cerebras so they also seem to be agnostic so runs on the same Apple hardware.
As TFA says, they are running the algorithm multiple times and they check that the results match, to guard against transient errors caused by radiation.
The permanent errors caused by radiation must be identified by periodic self tests. When the permanent damage is in a redundant structure, e.g. as mentioned in TFA when they find some memory bits that are permanently damaged, they must avoid using what is damaged.
Eventually radiation will destroy something that is essential, but until then the Snapdragon CPU should be usable.
Flying a helicopter on Mars was inspiring and useful for scouting, etc. But maybe the best thing coming out of it is undeniable proof that off-the-shelf hardware without radiation hardening is perfectly viable on Mars if you can just reboot it fast enough
Off-the-shelf hardware is usable, but instead of smartphone CPUs one must use the so-called AE (automotive-enhanced) variants of the same ARM cores that have been used in smartphones.
The automotive variants allow the use of multiple redundant cores, which check each other for errors. This would allow a much better performance than NASA gets today from a Snapdragon, due to being forced to run multiple times each computation, then to verify that the same results have obtained.
There are off-the-shelf redundant CPUs of this kind, designed for use in cars and other vehicles, i.e. for a goal much closer of what NASA needs than smartphone CPUs.
The design of the electronics for the Mars helicopter was a very low-effort project, because too many people were skeptical about its chances of success. In other circumstances, it could have been done much better.
It looks like the FPGA that monitors/controls the redundant/lockstep CPUs might be radiation tolerant. From [0]:
"..the critical FPGA which is always on for the duration of the mission, the radiation tolerant ProASIC3 is chosen with the military temperature grade (-55 C to 125 C) and -1 speed grade to mitigate the degradation in the propagation delay caused by the total dose radiation. The single-event upset (SEU) is mitigated with triple module redundancy (TMR) in the FPGA design.
...
The FPGA device is a military-grade version of MicroSemi’s ProASIC3L, which uses the same silicon as the radiation-tolerant device from the same family."[0]
The specs from [1] say there is also a specific radiation-tolerant variant.
So it looks like the CPUs themselves have dual lock-stepped cores, and the CPU checks for errors each cycle. If there's an error it flags the FPGA, which switches to the other CPU.
Only the microcontrollers are automotive redundant CPUs from Texas Instruments.
The high-level control and data processing is done by a now very old smartphone Snapdragon 801 CPU, which has no redundancy and it runs Linux. That CPU uses 4 custom 32-bit Qualcomm Krait cores, which were extremely fast in comparison with the radiation-hardened CPUs available at that time, but which are very slow in comparison with the current automotive CPUs or smartphone CPUs.
Nowadays there are automotive redundant CPUs, using high-performance automotive-enhanced ARM cores like Cortex-A78AE or Neoverse V3AE, which are far more suitable for a space mission than a smartphone CPU.
Because Snapdragon does not have the right hardware, approximate redundancy is achieved by software, i.e. by running multiple times each algorithm and comparing the results, and also by periodic self tests.
This is better than nothing, but a hardware-redundant CPU would have provided much better performance.
As long as Mexico shares a border with the US the biggest consumer of such recreational drugs and poverty in Mexico there will always be drug cartels.
It is basically whack-a-mole killing or imprisoning cartel heads - there will be splinter factions and you will just get three just as nasty ones in it's place.
Interesting but it assumes the teens will bother to look at it.
We use a WhatsApp channel for our family to manage breakfast meetups and who needs what from the shops or the pharmacy (they are on our healthcare plan) and general conversation about events or troubles and parental advice in their lives.
One kid live on her own with her bf a few minutes from us but she can't drive so we sometimes have to pick her up from work.
It gets muddled but works for us as the rule is no pet photos unless it is very cute (cat with a dustbin cover on his head) or inspirational daily quotes.
