SpaceX Starship struts its stack to show it has the right stuff

Grikath

So... the equivalent of 5 mins of LA daily gridlock? Even less time if you calculate the CO2 produced making all those semistationary wheeled tin cans and the roads they're on into account.

So yeah...

Sadly, the catastrophic impact with Apophis asteroid isn't going to happen in 2068

Grikath

Re: placing it even closer than some satellites in geosynchronous orbits

Urrrr.... you really don't want that to happen....

Asteroids like that ( by current estimates) aren't solid rock, but rather an aggregate clump. If it hits a satellite at the speed it is going the result will not be pretty. At all....

A direct impact by the asteroid would be significant, but not "world-ending" , despite the Doomsayers. But at least it'd hit in one spot. What would happen after a collision is anyone's guess, but the next pass of the remains would make for Interesting Times.

We've seen things you people wouldn't believe. A halo of light polarized by a gigantic black hole's magnetic field...

Grikath

Well.. The science says that a theoretical black hole of the mass P9 is supposed to have would evaporate ( or explode, depending on your taste ) within nano- , if not femtoseconds after creation. With an event horizon so small that single atoms seem large in comparison.

Not exactly a likely candidate.

Grikath

Re: Black hole in 'has quite mundane magnetic field' shock!

To be fair...

The field only has to accelerate the plasma up to ~c to avoid the event horizon in an orbital equilibrium. And the plasma can have quite a bit of a run-up to get there, especially in a spiral setup. It doesn't have to race around a tight corner like in the LHC or your typical fusion reactor as well, locally the field is "forward only".

So you can get quite a lot done with a "modest" field.

On the other hand, the Danes/Russ/Swedes/northern Slavs(!) didn't go in for Writing Complaints Down much. If it wasn't worth being sung by a Skald, or entrusted to Runes, it wasn't worth mentioning..

So the primary sources we have just might be a tad biased, and not wholly represent the opinion of the Vikingr themselves.

Intel told by jury to pay $2.18bn to VLSI for ripping off two semiconductor patents

Grikath

Re: completely artificial construction

Dunno about the "artificial construction"...

VLSI is simply the "legal arm" of NXP, which is the chip-fabbing part of the Philips blob. It makes sense in a way to incorporate the patent-wrangling part, given that it's a specialism in and of itself nowadays, and there's a measure of flexibility needed there that you just can't get as part of the main corporate/production body.

Especially when you have to play legal ball in the US, which is ..shall we say.. quite typical when it comes to stakes involving the unholy mess of patents and payouts. Choosing Waco is part of that. It's not as if worthies as Apple and Intel and... don't shop for "friendly" court districts or anything..

This isn't some shady ambulance chaser with some stupidly-obvious US patents trying to wring some cash out of a victim. This is ultimately a slugfight between Philips and Chipzilla involving real patents used in real tech.

And it'll drag on a bit, I reckon.

Re: Wonder how this will impact UK banks with no US presence?

Patents are national grants , so a US patent is not valid outside the US. The move is mainly against trolls in the US.

The UK/EU is also not really a place where patent trolls thrive, simply because the payouts on a possible win are much smaller and more based in reality ( starting with the simple issue of requiring someone to actively use the patent for something other than litigation in a lot of cases...) , and the UK/EU patent agencies are ( as yet ) a lot stricter in what they allow as a patent, so there's far less "frivolous"/obvious/insane patents that can be used as ammunition in a case compared to the situation that has evolved in the US.

University ordered to stop running women-only job ads

Grikath

Well... It's the TUE.. The "ability" bit for any faculty position is a given.. They've got no "fluffy subjects" there.. It's engineering and/or applied physics all the way..

Which is the main problem with that 30% goal... There's simply not that many women making a career out of that level of hardcore science.. They're aiming at rougly 5-6 times the fraction of women actually available.. Even if they fish in the international pool, that's quite a tall order.

The Moon certainly ain't made of cheese but it may be made of more metal than previously thought, sensor shows

Grikath

Alternatively...

The Moon may have had overall less metal per olympic-sized swimming pool when she formed, but we also know quite a lot of that did never separate out into something that resembles the lovely little life-preserving dynamo the Earth has.

The Moon, especially the outer bit did cool down rather rapidly, so it's entirely possible that the concentration of metal in the crust is higher than here on Earth. Especially when you realise that the Moon must have received some core material from Theia, and possibly proto-Earth, depending on how big of a Bang that was..

2GB monster

I worked for a PC manufacturer in that era as tech support/repair shop , and having access to Stuff We Never Could Afford Ourselves we did load up a machine or two with ...shall we say... excessive specs..

So yes.. there's been at least one Win95 box with 2 GB because we did build one, to see if it would actually work, mostly.

From memory: Yes it worked, even though any performance improvement past 64MB was actually negligible, and it did have problems addressing the full memory space. It did work pretty well ( and lightning-fast for the time once you got stuff loaded) because we resorted to using the overkill past 128 MB as virtual hard disks. Which did work a treat.

We did get a serious bollocking over it, because welll... Using expensive server-grade hardware for Experiments tends to be Frowned Upon From Above... But hey... For Science!! ;-)

Re: future orbits?

At 16 to a minimum of 5 lunar orbits that gravitational tug is so small that any deviations in orbit would end up in the realm of geological timescale, not human generations.

At its size, a chance encounter with a decent-sized rock would add more random momentum than Earth + Moon could ever do in a couple 100k years.

Edited to add: A gravity assist requires losing mass. Unless that rock has a method of shedding mass as it's going into a gravity well, it's a zero-sum equation coming out.

Grikath

So...

Given that lunar orbit equates to one light-second ( give or take a couple of olympic swimming pools) ...

This approach will be at 13 light-seconds, closest approach within a reasonable timeframe will be 5 light-seconds, and the orbits don't even intersect. It just comes close...ish.. For a given value of "close".

Not a threat, but close enough to toss a probe or two at it to see what it's made of now that his Muskness seems to have this rocketry thing mostly sorted out.

Trump issues toothless exec order to show donors, fans he's doing something about those Twitter twerps

Grikath

Not so sure it will be ineffective...

IANAL, but,,,,,

The problem for the big social media platforms may not be that this executive order may or may not be effective in and of itself. Their big problem is that it weakens their protection on one of the more contested powers on their platforms: their ability to edit or even delete self-published material, even though anything published may well not be illegal/obscene/whatever at the location of publishing.

Trump is, by far, not the only one that has run into the rather...haphazard.. and uniquely US-centric morality of "staff editing" that takes place on social media platforms. He's simply one of the top-profile ones, who doesn't have to run the infamously opague and boobytrapped hurdles to figure out what in your post has offended the Powers that Be on your social platform of choice so that it doesn't get published, or even gets you an appointment with the Banhammer.

Between the litigious nature of US society, and the rather sizeable group of people who feel Offended by censorship actions on social media platforms, the indirect effect ( and possibly actual purpose) of this executive order is the threat to open the floodgates to a deluge of lawsuits which up until now were blocked by that lovely little special protection of those social media platforms. Death by Papercut....

Trump himself may be the self-evident embodyment of the "cockwomble", but even while he may not be the brightest bulb in the bunch, his handlers are not stupid. And the threat of a ton of lawsuits that cannot be directly attributed to the Presidents' Office is a lovely little crowbar.

And so subtle that most news outlets have missed this implication outright.

Not going Huawei just yet: UK ministers reportedly rethinking pledge to kick Chinese firm out of telco networks by 2023

Grikath

Scepticism...

This thing has doing the rounds for a bit now, but the whole Huawei Spai Thing™ is getting rather silly...

Especially since any system Huawei may be able to incorporate in their gear to Spy On US runs into the same problem the also much-discussed Three-Letter wishlist item of a government-mandated backdoor into mobile devices in the Land of the Free... It simply doesn't work in the end.

Whether Huawei would use a hardware, firmware, or software approach to accomplish a Phone Home service other than proper diagnostics, it would be found and probably cracked within months if not weeks. It'd simply be a matter of who, not when. Whether "Intelligence", White/Black/Grey Hats, (commercial) vulnerability research, or plain oldfashioned tech-savvy criminal organisations, there's too much glory and $$ to be had from cracking that system if it were actually there. Everybody + Dog that is remotely capable would be all over it.

Yet we still have to see a single shred of credible evidence. And I doubt that Vulture Central would miss the chance to blow up the front page in extra bold capitals if there was, and they could nail an exclusive.

And as yet.... nothing.

If American tech is used to design or make that chip, you better not ship it to Huawei, warns Uncle Sam

Grikath

I can see this going well....

"Essentially, chips manufactured overseas using US software or hardware cannot be shipped to Huawei or any of its subsidiaries without Uncle Sam's permission. That means that even if the semiconductors were commissioned or designed by Huawei and manufactured by foundries outside of the States, the chips will still be subject to export limits if the manufacturing processes use any US equipment or design tools. "

Between the mess that is the USPTO when it comes to patents and its relation (ahem) to other patenting agencies elsewhere in the world, corporate cross-licensing, and corporate presence demands, what exactly is "US software or hardware" ? Or is "the US" trying to Claim it All if there's even a shred of "US technology" in a production/supply line? That'll go down well...

And with the way this is stated, well after the fact as well.. This would apply to machines/production lines that may well have been built/ordered years ago...

I can see this one turning to Interesting Times if they're really going to put their foot down on this. And not for Huawei or ZTE.

Re: Creepiness factor

In a sense, the technology is already here...

Any of the methods of measurement mentioned in the article , including the brainwaves, are established, if sometimes experimental, technology and have been demonstrated to work. Quite a lot of them actually are used in practical applications and research aimed at the Betterment of Mankind ( and as always, military applications..) . The aim there is usually control/interface, but something has to be measured to be used as an input...

Allowing for maturing of currently experimental/developing control tech, which we will see if this whole AR/VR thing really does become practical one day, and before that in gaming consoles ( of which quite a bit is there already..) it's simply like tracking the mouse cursor and registering clicks. The same kind of data.. Has a very legitimate purpose for the system, can very much be abused...

Which is why I wondered why they'd bother to patent this at all.. Until I realised we're dealing with the USPTO here.. The one allowing for Rounded Corners, and the addition of "on a mobile device" to well-established tech, and....

So how do the coronavirus smartphone tracking apps actually work and should you download one to help?

Grikath
Boffin

Bluetooth (alone) won't work.

The granularity of the system is several times larger than the actual direct infection radius of anyone actually infected. Even with bad reception you're talking 5 meter radius, running up to 10 meters. That's a lot of of area where people can be in, and be in the "watchlist". Especially over two weeks, the supposed incubation period of Covid/SARS2

This means that the "alert bubble" is orders of magnitude wider than it needs to be. This also means that the spread of the alert/virtual infection in this system is several orders of magnitudes faster than the Real Thing™. In short, within a week or two everyone using this app will have been "infected". No difference from a total lockdown. This is "basic" math used in modelling, including epidemiology.

So unless a Bluetooth solution also includes mitigation or selection it's practically useless. It must at least consider frequency of contact and proximity to avoid you being "tagged" because of a one-off "contact" two weeks ago. And a lot of other things to give at least a decent approximate of the chance you have indeed been in infectuous contact with someone who has developed Covid/SARS2.

Else it's just a panic-spreader. Well before any issues over privacy, slippery slopes, and a very ..insidious.. introduction of mass surveillance in our "free" society.

Good luck pitching a tent on exoplanet WASP-76b, the bloody raindrops here are made out of molten iron

Re: Puzzled!

The "it's a gas giant" bit is correct..

Jupiter ( and for that matter, any gas giant) will have Iron Rain somewhere as well. With enough metal content, the inner temperatures will make it inevitable. The difference with WASP is that one side of the planet gets stoked up hard enough that this iron actually reaches the surface layers where we can detect it, instead of being hidden by several 1000's of miles of boring methane, ammonia, and water ice.

Huawei claims its Google Play replacement is in 'top 3' app stores after Trump turns off tap to the Chocolate Factory

Re: Individual developers not allowed

Just checked the info the App store has on that, and it's not as if they don't allow individual developers.

It's just that they make it pretty clear ( use of services : 7.3 If You wish to use the Services in order to offer Paid Products to Users You must enter into a Merchant Service Agreement with HUAWEI.) that they only allow paid apps if you're a company. Something-something taxes.... It's not as if they're making a big secret out of it. In fact, they're terribly up-front about it, and make the neccessary information blindingly obvious to find.

And honestly, selling apps through an app store is (international) trade, and as far as I'm aware that requires having a company in most jurisdictions. Even if it's just a one-man company. Because something-something-taxes.
