Re: I can't believe no-one's mentioned TeX versioning yet

So that means we have Linux asymptotically approaching τ (tau)!

(Still sad we passed the terminator kernel version without much of a fanfare!)

"... (though TESS will be on a "flight proven" Block 4, ..."

<pedant>

I'm pretty sure that it's the last of the Block 4s and it's a new booster (B1045 I think). The design is flight proven, but this booster isn't.

As you were gentlefolk!

Re: Not Surprised

"There are few good reasons not to use 2FA (and I can't think of any outside of, possibly, some for users with disabilities)"

I have no cell-phone coverage, thus whenever I have to receive one of these code numbers, I must drive a mile or so until I reach a safe place to stop and wait for my 'phone to wake up to the fact that there is now signal and for the SMSC to wake up and forward the text messages it has accumulated for me, and once I have received the code I have to drive back and hope that the process I have started will allow me to carry on from where I left off.

This is tedious.

I do - in fact - have 2FA enabled on my google accounts and I always have to go through the "more options" | use backup codes route; but at least Google provides this option, my ire is directed at the other sites which refuse to acknowledge the possibility of less than 100% coverage for 100% of all networks!

Given that there are about 41253 square degrees in a sphere then reducing the search area to just 60 is not bad though.

Kudos to BitMainTech for the use of "thrice" in a world of the ever-increasing Americanisms: three-times, two-times and even - the horror of it - one-time.

Re: Blind support

"So on this case, Hutchins denies the charge. He might be innocent. He might be guilty."

<pedant>

He is is definitely innocent, since he has not been proven guilty.

That's what presumption of innocence means.

It's why the verdict is either guilty or not guilty, since one is presumed to be innocent, there is no need to be declared 'innocent'

Re: do not enter the hypen!

"The reason for that is that credit card fields have EXACTLY 16 spaces in them.

Sometimes, you just can't fix stupid."

<pedant>

Nor, apparently, can you fix ignorance.

American Express card numbers have 15 digits (4 + 6 + 5), and --- several years after they introduced the 3-digit security CSC (like all the other credit/debit cards) --- I can't find a single payment service (Sage, Worldpay, any of the banks) that will allow you to specify it (the 3-digit CSC) rather than the 4-digit number that is printed on the face of the Amex Card.

Sigh!

</pedant>

In 1986 I wrote a credit card acceptance function for MUD II that stripped out the spaces and --- in every card acceptance page I have authored since then --- that continues to be the case; it seems I'm in a minority of one.

Re: timetables

"When your No 7 to East Acton comes along, there will be three more right behind it all empty. such is the nature of London Busses."

<pedant>

Strictly speaking it's more to do with the nature of London traffic than the bus itself.

It's always a problem in cities and towns; buses would be so much more consistent with the published timetable if it weren't for other road users and --- more importantly --- passengers!

Re: 5 star apple screw driver

"Found the exact battery part from China (40% of apple cost) ..."

Have one of these (it is Friday after all) --->

Though you do need to take care with some of the replacement parts (even the branded Apple parts are probably from China, so it's not the nationality) as they may be poorer quality - possibly more prone to catch fire, or lesser capacity.

There is a difference between noname and branded replacements: I've repaired my wife's phone's screen with both types and the Nokia branded part doesn't cause the phone to freeze and require a reboot and didn't cost all that much more than the noname brand.

"He received a fixed penalty notice in the post and was horrified that he didn't get a copy of the photo."

It used to be asking for the evidence (after a suitable delay) was a good way to get the charge dismissed as the police were apt to dispose of the photographs before the 6 weeks had elapsed.

(Though now I think more critically about this, it's probably an urban legend. Sigh!)

Re: Lots of shielding requires lots of fuel.

"I dont know how much the propellant for a gun like this is but I'd bet its a shit load cheaper than rocket fuel ..."

If one used a railgun then one isn't dealing with a propellant at all, just a source of electricity.

Another advantage is the lack of noise from the explosive combustion of the said propellant, leaving only the sonic boom, so watch out for a sudden brown-out followed by a loud bang (and the sound of breaking glass)!

Re: Odd belief

"Automatics because hard to drink coffee, eat donut, steer AND change gear"

Don't forget answering the 'phone and texting!

That said I've never seen the point of doing more work than necessary and my VW DSG can change gear in milliseconds, so why should I muck about being all macho and insisting on a manual? (OK in this case it's pretty much just a manual with an automatic clutch (or two), but my previous cars have all been traditional automatics and there was nothing more satisfying than leaving a manual driving adversary-- sorry fellow driver in the next lane, in the dust at traffic lights - I defy your average driver of a manual car to outperform pretty much any automatic gearbox equipped car driven in "kickdown"!).

Meanwhile was there an earthquake on the night in question?

BTW I am a Brit. and I don't bother with the handbrake either, when the car is in "Park" and the ground is flat.

" I will transition to rocket powered paper weights as soon as they become available and fervently support research into ion drive paper weights"

<pedant>

The rocket-powered paperweight is only good for short-term usage, so as long as you only require your papers to be held down for a few minutes at a time then you're OK; the ion-drive paperweight is a long-term solution for those that require their papers to be weighted for months (possibly years) at a time. They address two different sets of requirements, so you don't need to replace your rocket-powered paperweights with ion-drive paperweights.

Re: Radar is well proven, why has it been ignored by Tesla ?

"My Audi is now more than five years old, and it has a driving assistance system which the manufacturer does not market as an "Autopilot", rather they call it Adaptive Cruise Control."

The VW/Audi/etc. system doesn't do autosteer AFAICS.

Since you are still steering the car you are less likely to be disengaged from the road conditions in which you are driving. (Though I find myself entering a "fugue state" on older Motorways if I am not careful.)

If I recall correctly Mercedes and BMW have "lane keeping" assistance features, so they will have some form of autosteer, does anyone know what the accident statistics for these cars are like?

Possibly the main difference between all the cars with this kind of self-drive ability is the fact that the Musk is so high profile and keeps talking about it?

Re: own EV happens to have the exact same problem

"right, lithium being the second most chemically reactive substance in the known universe, and the most reactive of all of the metals."

Err. No. Lithium is the least reactive of the Alkali metals (Group II); in this case reactivity increases as you go down the group. So Caesium would be the most reactive of these metals.

There is an entertaining film I remember from my school days where each metal in turn is reacted with water, which demonstrates this point quite explosively

Here's a YouTube video that contains some of the scenes from that film: (https://www.youtube.com/watch?v=HvVUtpdK7xw)
