Chip fab Intel said to be using better chip fab TSMC to make 5nm Core i3 processors, 20% of its non-CPU parts

imanidiot Silver badge

Basically this. 5nm is what they call a "node" name. It sort of denotes how large a gate would have been had things kept scaling according to Moore's law. In practice gate length hasn't shrunk since the 45nm node (iirc) and the introduction of FinFET gates.

It'll be a long while before China can catch up to even the mid-line photolitho systems of ASML, Canon or Nikon. There's a scary amount of technology working together in a photolitho scanner to the point where they might just be the most complicated machines on earth.

"the founding fathers were thinking in terms of flint lock muzzle loaders with a maximum fire rate of 3-6 rounds per minute."

No they weren't. Friggin private navy's were a thing back then! "They were thinking of flink lock muzzle loaders", yeah sure, but that 30 gun ship is fine too. Puckle guns also existed. Privately owned field artillery was also fine. The first ideas and talks about faster firing weapons and machine guns were certainly already happening. Multiple of your founding fathers had a keen interest in the technology and were certainly well aware of were things were heading. If they had any intention of limiting the second amendment to muzzle loading long arms or black powder pistols they certainly would have put more text in there.

Re: Stress test? What stress test

Depends on what the hydraulic pressure controls. If the fuel/oxidizer control valves run off that same hydraulic circuit for instance I could imagine you'd want to shut things down before pressure drops to a level where you might no longer be able to control the valves.

Re: Horse bolted a long time ago....

Boeing was doomed the second it was taken over by MD management and put the managers in charge and in a different city, so they couldn't be bothered by those pesky engineers.

The Boeing of the past, that put out the 747 as a side project just in case the SST didn't workout, that designed the iconic 737 and played a huge role in the development of military and passenger aviation was led by engineers first and foremost. People that had a feeling for their product and understood what it was they let roll out of the hanger doors at the end of the production line.

Re: hit their full power of 109 per cent

This.

100% is engine power at optimal fuel ratio. For liftoff you want a little bit of extra oomph to get things moving, so you go a bit "extra" and get more out of the engine for a bit. The engines throttle down as the craft gets moving and approaches "Max Q" then throttle back up to 100% for most efficient burn until MECO.

Re: converted from being reusable units

"Clearly RS-25 should be used on the upper stage which would require a re-design for lighting the engine without ground support equipment and optimisation for use in vacuum."

But why would they if they have the perfectly good and flight proven RL-10 on the shelf. I don't think there's any upper stage that would benefit from the massive grunt of a vacuum RS-25. Plus the RS-25 design doesn't really lend itself to being an upper stage engine. Redesign would have to be so radical that it might as well be a completely new engine. And if you go that way, why not design a completely new engine, optimized for todays manufacturing methods.

Boeing confirms last 747 to roll off production line in 2022

Re: Who rides the top deck?

Indeed, as commented, crew rest area. Small galley, some seats and a few beds/bunks to sleep. 747 freighters usually fly the longest international routes, so probably have a crew of 3 or 4 (a pilot/captain, co-pilot and 2 relief pilots.)

What’s that in CES heaven, is it a star? Or is it that damned elusive flying car?

imanidiot Silver badge

Flying without wings is super inefficient. Small "personal" flying craft will never be common and they will never be allowed to fly over cities. Accidents in aviation happen. GA accidents happen more often than people think, but nobody worries about it because all the procedures in place make it unlikely for anybody but the occupants of the plane to get hurt. If hundreds of thousands of small craft were suddenly allowed to fly over built up areas it's only a matter of time before "Flying car plummets into childrens bedroom, 3 killed in horrific crash!" becomes a headline. Unless we can invent some sort of fail-proof (or super highly reliable at least) anti-gravity drive, flying cars just won't happen.

It looked plugged in

I've had a similar encounter, though in my case if you just peered behind the computer it LOOKED plugged in on that end. After feeling around it turned out it WAS plugged in, but only the plug! The cable itself had mysteriously disconnected from the end and was dangling behind the desk on other cables out of view. Some other cables lined up so that when you peered behind the case to just look, it looked just like the network cable was in place.

Re: Unbreakable Enigma

The Germans had also effectively hobbled any involvement of the Dutch resistance through Das Englandspiel meaning that any intelligence gleaned from Dutch resistance through SOE was not believed (even though it told them the fields right next to the bridge at arnhem where dry enough to land on, and not flooded like the army believed for instance) and Dutch resistance itself was neither armed nor aware of the attacks until the troops were already on the ground.

Operation Market-Garden could have been way more successful than it turned out had the resistance been aware and been able to sabotage supply lines or block roads and had the planning for the operation been better. As it was, it was the plan and especially the timeline was just way too ambitious ("A bridge too far").

Chuck Yeager, sound barrier pioneer pilot, dies at 97

imanidiot Silver badge

Yeagers account of that particular crash in no way matches what happened according to the lead test pilot on the NF-104 AeroSpace Trainer program. His account on the program and the incident is very interesting reading. http://www.kalimera.org/nf104/index.html

I can't help but think there's some sour grapes that might be coloring the account somewhat, but the way it's written certainly matches much better with how one would expect such an aircraft to behave in that situation. The dramatisation in "The Right Stuff" was precisely that, pure drama based in no way on reality. Yeager himself seemed unwilling to admit he may have screwed up.

imanidiot Silver badge

The right stuff, in some circumstances

Yeager was an exceptional pilot when it comes to aerodynamic flight. No question about it. He did many amazing things.

"Both works depicted Yeager's belief that astronauts did little real flying and ought not to be compared to test pilots who had to exercise exceptional skill day in, day out."

But this right here is exactly why Yeager was passed over for the space/astronaut programs. He didn't "get" non-aerodynamic flight or orbital mechanics so in his mind, astronauts did no flying and were "inferior" to "real" test pilots (not withstanding that many early astronauts were outstanding pilots in their own right, all had completed test pilot school and contributed immensely to the understanding of spaceflight, orbital mechanics and maneuvering nor that many flights were saved only by the astronaut on board. Were they pilots? Not in the traditional sense of the word, but they certainly weren't monkeys along for the ride as Yeager painted them)

Re: Why only 2 oz ?

The rocket equation is a harsh mistress.

If you need to bring back mass, you need to change it's velocity, for which you need fuel. If you want to bring back more mass, you need more fuel. You also need more fuel to bring that extra fuel in the first place. And a bigger rocket to lift that extra fuel (that also needs to burn more fuel because of the extra fuel to move the added fuel). You also need a bigger return capsule, which adds mass, requiring more fuel (and a bigger rocket to bring that fuel)

It's a basically a balancing act on how much mass you can bring back versus how much fuel you can stuff into your spacecraft and how big the rocket you have available to bring it to space is.

"That's pretty impressive to be able to measure 60 grams or less of material.. The craft itself weighs somewhere around 1-2 tons depending upon how much fuel is left!"

Actually, with this method they can measure to tenths of grams accuracy! It's mindboggling the hacks they've pulled off to get this far, including pushing their camera and navigation systems far beyond the original design specs to even be able to sample from a site that small. Original target spec was an area 50m diameter, the largest potential site they had available was 16m diameter. The LIDAR system that was supposed to be the primary navigation method turned out to be unsuitable, and the backup Natural Feature Tracking system was pushed far beyond initial design specs to be able to pull this off. It's an impressive case of "make do".

Re: Its not unknown.....

Same thing pretty much for the full size version. They can get a bit terrritorial at low altitudes but usually they put in a few mock attacks, then go off to sulk. Definitely a full size plane isn't going to take much damage from a hawk or falcon.

I've encountered peregrine falcons at 2500 meters AGL.

Also fun are storks. They pretty much behave like living miniature sailplanes. Prefer to fly "opposite" or equally divided in a thermal, and seem to get annoyed if you don't join a thermal properly like you would any other sailplane. Since the glide speed of a sailplane is usually much better and thus we cover more ground oftentimes it seems like we become the thermal indicator for storks.

Aviation regulator outlines fixes that will get the 737 MAX flying again

Uhhhmmm, how about no?

From the article: "Changes to horizontal stabilizer trim wire routing installations are also required, to give pilots better control."

yeah, no, not so much. Unless you count not losing electrical systems as "giving pilots better control"

From the FAA's preliminary report on the return to flight of the 737 MAX:

"6.6 Electrical Wiring Interconnection System (EWIS)

Requirements(§ 25.1707)As part of the FAA’s review of these design changes, the agency re-reviewed the entirety of the 737 MAX horizontal stabilizer control system. This review revealed that the physical separation of the horizontal stabilizer trim arm wiring and the horizontal stabilizer trim control wiring does not meet the criteria specified in 14 CFR 25.1707. This design standard was promulgated in 2007 and therefore is part of the certification basis of the 737 MAX but not of previous Boeing Model 737 airplanes. Certain wiring installations must have enough physical separation so that a wiring failure cannot create a hazard. (See 14 CFR 25.1707)."

"The stabilizer trim arm wiring has since been rerouted in 12 areas of the airplane’s Electrical Equipment bay and Section 48 to prevent a potential simultaneous short circuit between the stabilizer arm and control wiring and another 28VDC wire. "

Re: why aren't postal votes considered a fraud risk in the US?

a few hundred thousand votes, over a few hundred million... Not exactly pervasive now is it.

(Claims of) Pervasive voter fraud, in that comment, as related to Fascism, is about rigging elections so that the vast majority of votes are false and the outcome of the election is rigged, or claims to that effect. I have made no such claims. I'm also not saying in that hypothetical case those "few hundred thousand" votes are ACTUALLY fraudulent, but that doubt is cast on them. Investigation would be required, it might turn out all of them are valid. But in that situation you don't know. It causes delays that the current US social structure might not handle very well.

Re: why aren't postal votes considered a fraud risk in the US?

"The answers are lots more than has happened, and no"

Again, read this article https://www.npr.org/2020/07/13/889751095/signed-sealed-undelivered-thousands-of-mail-in-ballots-rejected-for-tardiness?t=1595405926137&t=1595410783748

Or this: https://sanfrancisco.cbslocal.com/2020/07/13/mail-in-votes-uncounted-californias-primary/

Or this: https://www.typeinvestigations.org/investigation/2020/06/18/as-states-struggle-with-vote-by-mail-many-thousands-if-not-millions-of-ballots-could-go-uncounted-in-november/

Now scale all those individual state election results up to national level. It USED to be about 1% of ballots were rejected. In the recent elections, in some districts it goes as high as 9 or even 14%. The last few US elections have all been rather close races. Lets say that with no fraud involved but the chaos ensuing from doing mail in votes on such an unprecedented scale, 2% of the votes get rejected. In 2016 that would have made the race too close to call in terms of popular vote and it could have swung the vote in terms of outcome in several states. So is it a good idea? ANY fraud gets added on top of this.

Is mail-in voting really a good idea? Especially considering the short notice with which politicians want to roll it out on such a large scale?

Re: why aren't postal votes considered a fraud risk in the US?

Uhhhmmm, so anyone that doesn't push the same narrative as the mainstream media is by definition far right? Have you bothered reading the links I provided? Sure limited amount of cases, usually small scale, but it proves the basis to be able to do it is there and that mail in voting is susceptible to it.

As to your other list:

Law and Order (sure, in a controlled and well defined way, but that's just a political right wing thing, not extreme right).

Pervasive voter fraud, I never claimed PERVASIVE now did I? I claimed that it's there! And how much voter fraud is acceptable? 0.1%, 1%, 10%? I claim we should aim for as little as possible and mail in voting doesn't mesh well with that. Changing to mail in voting at the last minute without years to prepare for it's deployment on a massive scale is just asking for trouble. Even if it's not downright fraud and honest mistakes, it's problematic.

National security, again, just right wing, not just extreme right wing. Certainly not just fascist

Xenophobia, not even involved

nationalism, I'm not even FROM the US, and nothing wrong with a limited amount of nationalism. Again, right wing thing, not just fascist

exaggerated patriotism, again, I'm not from the US. Certainly doesn't follow from my posting here.

And lastly. ALL those things need to apply, only the voting fraud problem is under discussion, and nothing I've said points to my thinking it's pervasive or rigged.

So again, please point me to any statement that shows I'm a demagogue or fascist. Just because I happen to agree to some degree with Trump doesn't mean I agree with everything he says or does. Just because I agree to some degree with ANYTHING doesn't mean I'm fully aligned with that group. Just because I think mail in voting is a bad idea if applied on a large scale and that there is evidence the system is open to abuse in the US doesn't mean I'm a fascist!
