Slack to fend off the collaboration competition with... a new logo

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).

Re: So...

"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.

Re: If the .EU can do it

Because the rules around the .uk registry don't require that the registrant be a UK resident.

They do specify the equivalent for the .eu registry.

That's just the way they were set up... Check the rules of your own registry.

NASA names the date for the first commercial crew demo flight

John Robson Silver badge

In theory they should redefine ‘economically viable’, although not for the 63ton launches...

John Robson Silver badge

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)

Ok, it couldn’t complete it’s final translation manoeuvre, so couldn’t *get* to land... designed to fail safe... no way to land at LZ if it can’t get there.

Re: Not a record number of cubesats

It is a record - for them... In the same way I can set a british record whilst still having had people from other countries do better.

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.

Pencil manufacturers rejoice: Oz government doesn't like e-voting

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).

Re: Elon & Drugs

@Spazturtle...

Looks like there is some conflict, but that it is falling on the side of the states being allowed to make their own laws. I'm still running with BBC on this one - since there is quite an extensive body of legislation that explicitly declares it legal.

Re: Holland was clearly making a point..

>>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.

John Robson Silver badge

Re: Holland was clearly making a point..

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.

So they ban mobile phones on forecourts (pointlessly) then expect you to pay with an app on the mobile phone they just banned...

Re: 2018 is the year of stupidly sized phones

"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?

Doing anything that would require a crash helmet suggests to me that you really ought not be unlocking your phone, and probably should be wearing gloves as well...

Re: "The detached sail will accelerate but the probe will decelerate"

"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.

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...

Re: ..am I the only one who noticed..

It would need linear momentum - and alot of it...

And a very significant number of assists, as you go faster past a body you get less time to be deflected, so the increase in energy is reduced.

John Robson Silver badge

Re: So what I'm wondering now...

I should probably add that there is also some (repeated) trade of energy with Venus - gravity assist.

Whilst the probe arrives and leaves the gravitational well of Venus at the same speed, its direction is changed (hence the new orbital path each time) - and that direction change is a velocity change, which requires energy - which is exchanged with Venus.

So Venus does change orbital velocity, but its mass is such that the change in velocity is negligible.

John Robson Silver badge

Re: So what I'm wondering now...

No - speed is increasing as it 'falls' to perihelion, and then slowing as it climbs to aphelion.

Velocity is both speed and direction, the speed is changing, and the direction is changing as well.

What is constant (ignoring drag/radiation pressure/any thruster based control input) is the energy.

Continuously trading gravitational potential energy back and forth with kinetic energy.

If the answer is anything longer than 5 minutes then I'm sorry, but there is no rotation frequency I can use that will protect either of us.

If the answer is under 5 minutes then that's great, that's when I need to consider password rotation...

UK.gov to roll out voter ID trials in 2019 local elections

John Robson Silver badge

What a ridiculous concept...

"Voters in Mid Sussex, Watford and North West Leicestershire are testing pre-issued poll cards, which are seen as a less restrictive solution. If someone turns up without the card on polling day, they must present another form of ID."

Hey - at least the above is vaguely reasonable.

I suspect that the 44 counts are those where the 'right' person has turned up later in the day. How would impersonations of people who just didn't bother to go themselves be detected? Do we count it when people say 'Oh yes, silly me, I've had a busy afternoon' and leave?

I happen to know many of the people who man the local polling booth - so I'm pretty confident that I could only vote once, and no-one else could vote as me - but having to bring the card they posted me isn't a huge problem.

Having to bring photoID is a much bigger ask - even non photo ID is tougher now. I happen to have had a lot of dealings with various government departments recently, but I but those letters are "not a utility bill"..
