Comment Seems silly, other than domestic propaganda. (Score 1) 130

I don't understand what this is supposed to achieve.
The US decided early that cutting cables is pointless, whereas tapping cables was often very informative.
If China or India or Japan or Korea wanted to curtail cable traffic across the Pacific, they all could easily damage the key cables with plausible 'accidents', no need for fancy deep diving RoVs.,
It may simply be an effort by China's NOAA equivalent to gain stature (plus funding) in China's more militarized political environment by showing that their gear can be weaponized.

Comment An investigation, not a grounding. (Score 4, Informative) 54

The FAA's call for an investigation is quite consistent with their mandate to improve safety and efficiency of space transport.
However, nowhere is there a call for grounding the rocket.
Clearly SpaceX will stop launching until they are confident they have found the cause of this failure, they hate losing boosters for nothing.
But they are free to launch as they wish.

Comment Re:And how is Linus qualified to comment? (Score 1) 73

Well, he's worked on the interface between hardware and software for decades with considerable success.
He is still very actively engaged, down to the minutiae of the processor design elements, so is as authoritative a source as we have, imho.
Follow the discussions in RWT (https://www.realworldtech.com/forum/?roomid=1 ), he participates there regularly.
They cover the interface between hardware and kernel software in depth, better than anything outside of the AMD or Intel workshops.

Comment Ingenuity is really spectacular engineering (Score 1) 22

Here on earth, the official record altitude for manned helicopter flight is 41,000 feet, set over 50 years ago by Jean Boulet, a Frenchman.
Ingenuity is zipping around in the Martian atmosphere at about 115,000 feet equivalent.
Just stunning performance, without equal here on earth.

Comment So why was no contaminated animal host ever found? (Score 0) 211

The claim that raccoon dogs were the hosts for Covid would be much more plausible if anyone had actually found one.
People looked hard for the animal vector, remember that pangolins and snakes were looked as possibilities, nothing was found, nor were any infected raccoon.dogs.
So this piece is somewhat informative as to where the virus propagated, but not helpful for tracing the origin imho.

Comment Whatever the culture, it is not working (Score 2) 97

I'm puzzled by the claims of 'breakneck pace of work'.
The various Blue Origin programs are all late, notably their BE-4 engine which they sold to ULA is now holding up the Vulcan vehicle the USAF is counting on for launching its future satellites.
But perhaps the shop is just so disfunctional that is is a struggle just to move forward. and any motion seems too fast.

Comment Re:Finally actions are taken (Score 3, Insightful) 62

Not so, imho.
Shareholders were hugely rewarded by massive share repurchases. The downside was that there was no money to do a 737 replacement, hence the -MAX kludge.
There was a time when Boeing's directive was to 'let no advance in aviation pass us by'.
Then the emphasis shifted to "shareholder value'., which worked great until it did not.
The good news is that the company can now get back to speed technically more cheaply than if Boeing had actually found the way itself.
The bad news is that they have lost the experience of innovation. I expect them to produce accordingly.

Comment Seems a PR move at best (Score 5, Insightful) 18

Given that this was a carefully built piece of malware, I'd be astonished if there was just a single command domain.
Unless MS and friends have parsed the entire code, one should assume that there are at least a couple of backups, so the effort is not lost by losing this C&C domain.

Comment Musk is an inspiration (Score 1) 72

Musk will hopefully inspire a new generation of CEOs, people who actually know what they are talking about, rather than Wall Street sycophants.
Delivering repeatedly on technically challenging projects makes him super credible, so if he is willing to put his name on a Tequila, there will be lots of buyers.

Comment Re:Nvidia won't kill ARM (Score 4, Interesting) 87

It seems uneconomic for Nvidia to pay $32B to get an exascale processor development team.
However, Hauser does have a point. Google has gradually morphed Android from open to proprietary, an example Nvidia has surely studied cafefully.
A gradual introduction of Super Arm features by Nvidia might well allow them to shift the Arm ecosystem towards a more proprietary structure with Intel like margins for Nvidia.

Comment RE: Curious (Score 1) 124

The limitation is the heat produced. A reactor heats up a working fluid, steam or even helium and a turbine generator extracts some of that heat to make electricity..
The rest of the heat, usually about two thirds of the total, has to go somewhere, either the ocean, a river or even the atmosphere. Deep underground, none of those are readily available.
Interestingly enough, outer space would be very good, energy can be radiated away in infinite quantity, but other than a NASA workshop in the late 1980s there has been little work done afaik on the idea of power stations in space transmitting energy back to earth.
