It does, which is why you limit the reach of software. You don't need to log with root level rights.
You get sent data by all and sundry, write it to disk.
Why does that need root privs? (ignore for the moment the perfectly good text based logging we used to have)
systemD might make sense in a few (mostly laptop related) cases, but it make serious compromises in terms of clarity and usability IMHO. No need for it on a vaguely stable system.
Unsurprisingly if you limit your focus to the people wearing seatbelts ... they make some difference.
How many of those crashes wouldn’t have happened if people hadn’t been so mollycoddled in their cars?
How many extra people *not* in cars were killed because ‘I’m alright Jack’ wasn’t driving with due care and attention?
Overall road deaths haven’t been dented by seatbelt introduction, popularisation or legislation.
Measure only people who have had a crash whilst wearing them and you see a benefit, look at society as a whole and it vanishes.
Citation needed to say that they have improved things as well...

Particularly interesting is page 8-10 if you don’t feel like reading more of it.
The death rate on the roads has had a steady 5% decrease year on year - completely unaffected by seatbelt initiatives or virtually any other ‘car safety’ feature. Medicine sure has improved though.
Who needs file transfers for a chat - just drop a link to your local ftp server.
VoIP can be replaced by talking with people, or any other VoIP solution. Not every tool needs to do everything.
You just sent them a note with the room in it... how hard can it be?
And no inline images make for a much cleaner chat... in slack mine are generally unexpanded (and the chat is better for it).
"Because those systems do have business being on the same bus."
No they don't. I can see that you might want a one way data signal from the ECU etc to the display system of the car, but there is no reason to have unrestricted bidirectional data flow.
I can't think of anything that would want to be displayed that couldn't be gathered from:
- A GPS receiver.
- A unidirectional stream (i.e. rev counter, TPS readings, error codes)
There is nothing that needs the radio to talk to the ECU.
Because they have a ditch path (the thames) and can autorotate in the event of engine failure.
Their flight paths are quite controlled.
"Hardly a decisive outcome to leave, when two thirds of the public didn't support it.
Hardly a decisive outcome to stay, when two thirds of the public didn't support it.
That argument goes both ways you know."
It does - but one of the decisions can be revisited, the other can't.
"52% confidence that I don't want a family"
I could either:
- use a condom/pill for a few years whilst playing with kids and talking with parents.
- get a vasectomy
Which is more sensible?
If in a few years time my life has changed and I *do* want a family, then one decision looks very foolish indeed.
It's more that there aren't that many payloads that need that much rocket...
Parker is the fastest thing we've ever lobbed, some very large satellites...
But in general satellites are built down to a mass limit so they'll fit in an economically viable launch vehicle.
22 tons to LEO (expended) is the F9.
63 tons to LEO (expended) is FH.
That's a huge difference, but 22 tons is alot of payload already - commercial payloads are typically closer to 4 tons (although some boost may be wanted, that will take some of the remaining 18 tons)
Although in this case it looks like it could possibly have landed safely on land... Not that you'd try it in this case, since a collision with the landing pad would be rather detrimental.
A perfect abort scenario... This is the reason we put launch sites on the coast...
I suppose I ought to say launch and landing sites now...
You can rub out a pencil, but you can still see where the mark was made.
Who is going to rub out a pencil mark anyway - the advantage of the paper system is that the paper is put in a sealed box, watched by multiple interested parties. Then the box is transported (still watched) to a counting location where it is unsealed (watched) and the ballots counted (still being watched).
We've had a long time, and much practise at this kind of thing, and many attacks have been tried... they have countermeasures in place...
"
Expanding 3G? Please. Here in the US of A, I can take you to several places where there is not 1G service. And every carrier has large areas without 1G service. Why are we bothering with 5G when the providers still haven't gotten 1G right?"
It is right - it's making them money - if you live in a not spot then that's your problem, not the operators.
>>If sending to more than three people (or more than 1 domain) then any decent client should default to BCC
>In my organization we frequently have triparty exchanges where everyone could contribute.
That's fine - three people in the same organisation wouldn't even trip my filter.
BUT if you sent it to ten people, then you would have to tell it that you really wanted it to be clear to all.
IF you sent it to multiple external domains then you would have to tell it that you really wanted it to a screwup.
Maybe three is a bit tight for some organisations, I'm only suggesting a default.
Could you mitigate this with an application-level security setting/GPO (on by default?) to BCC for corporate email clients so that you have to actively move addresses to the TO/CC field if that's really your intention.
If sending to more than three people (or more than 1 domain) then any decent client should default to BCC - and do so visually...

The launch escape for Apollo got tested...
" There was some doubt it would on Apollo, though it never got tested fortunately."
Of course the test flight was a technical failure, in that the booster used failed before reaching the appropriate altitude... The abort launch escape system however performed flawlessly, detecting the breakup and pulling the command module away to a safe landing.
Surely the absolutely best flight to have a booster failure on.
"Its a shame that this happened on the same day that the public transport system suffered a significant failure requiring a far higher number of people to work from home. I expect that the two are linked in some way."
Well yes - without access to their cat pictures by email the drivers couldn't get in...
"Fuelling up? I have to take my glove off to unlock the tank, but then I have to tap in my (longish) passcode to use the pay-for-fuel app. Sadly, my bike loves gas stations."
So they ban mobile phones on forecourts (pointlessly) then expect you to pay with an app on the mobile phone they just banned...
That's brilliant...
"However what I actually do about unlocking is use smart unlock to detect the bluetooth on the bike intercom to keep it unlocked (the bluetooth switches off with ignition) and it has a gloves mode so that I can still use the touchscreen with summer riding gloves on (when stopped!)"
Seems easy enough.
Anyone remember the good old days when you just typed in a pin to unlock a device?
"Re: "The detached sail will accelerate but the probe will decelerate"
Why ? This is space, there is no aether to decelerate the probe. The probe will continue at its speed, and the sail, being pushed by the laser, will accelerate further and go faster than the probe.
"
Because they are proposing two sails - one that is detached, and still accelerated by the earth bound laser, and one which is pushed by the light reflected from the detached sail...
That would be a retarding force.
Unfortunately I don't think that we could target one of the two sails from here, so we'd likely hit the 'back' back of the 'braking' sail, and accelerate it instead... Additionally the accuracy with which the second sail would need to be positioned for reflected momentum to target the prove would be insane.
VAT isn't a tax on their turnover, and they don't pay any, they reclaim it all...
I had missed the sales of cloud services... That's certainly more complex.. but let's deal with the big (and easy) problem of adverts first.
The issue of selling digital services is complex, particularly when multinationals sell to other multinational companies...
The heating could be secure in ten years - if it was rationally designed now.
It should have an RJ45 port, and acquire an address from DHCP. It should also grab an NTP server (or guess at the DHCP server, then pool.ntp.org if the DHCP server neither gave it one, nor acted as one).
It can then present a web/API interface over that local connection - which also offers firmware upgrade functionality (with a physical button press also required).
Anything that just has WiFi, and refuses to talk locally - only talking to some external server... Well, that's just dumb...
