ExoMars parachutes just about good enough to land rover safely on the Red Planet

Re: Ob H2G2

We've not designed rovers that can contemplate the rushing noise and their own existence before wondering if that big round thing will be friends?

UK government has 'no clear plan' for replacing ageing legacy IT estate, MPs report

Re: None at all @John Robson

I think that the civil service are completely hamstrung by the regular reversals of decisions.

There is only so much that you can plan for when the target moves more often, and more erratically, than a cockroach with ADHD.

Re: @Deanamore - Your analogy is flawed

Erm - there are differences between putty and having a real terminal which can do all sorts of remote automation...

I often run loops to connect to a bunch of machines (which can't necessarily talk to each other) and run a similar command on each.

John Robson Silver badge

And there are public options to make the setup even easier than that...

tailscale makes wireguard utterly trivial to deploy, and as mentioned the dedicated interface makes firewalls trivial to write and update.

Re: 70's electricty

"If we start extracting all that natural wind and atmospheric movement are we leading ourselves down another path to armagedden?"

If you start extracting it all you stop extracting any very soon after, you need the wind to carry on past the turbine to allow fresh wind in...

The theoretical max is under 2/3rds if I remember the numbers correctly. And of course there are substantial gaps below and around the turbines, let alone the size of the gap *above* them...

Re: Not just that

Anything which limits the amount of walking and standing you can do in a day.

You can get a coffee made, then go to the machine, get the cup and load the next pod.

You only make one trip per coffee, not two. And yes that *is* important to lots of people.

Re: Not just that

I was commenting on the overall attitude of "I don't need this user aid, so it's a waste", not the specific machine.

It's like my washing machine having the capacity to connect to a network - I can't figure out why anyone would want/need that (potentially useful for a laundrette to monitor usage and get notified of failures by the machine I suppose). However, it almost certainly adds next to no cost to the machine, and if it useful to even a very small minority then I don't have an issue with it being there *as an option*.

I have friends whose lives have been made massively easier by alexa.

I have had my life massively improved by things as trivial as keyless entry to a vehicle (something I used to dismiss as a gimmick).

Re: Not just that

And for those who have various disabilities what it has done is allow them to make coffee... not such a small thing any more.

John Robson Silver badge

Re: its not where, but what.

Yes - but changing those things is beyond the scope of "what do I do for my computing needs".

And if you are renting services by compute power you have a direct incentive to minimise the compute power needed, rather that "oh we have a big underutilised server, what does it matter"

We really need Hubble to be online when JWST is online, so we can calibrate it.

"I suggest that the very high capacity home connections are way more niche than many here might think and of those who do have very high capacity probably barely use it anywhere near full capacity."

Whilst I agree with your first point... I don't have the high speed connection for the bandwidth, but for the latency and consistency which fttp provides (an order of magnitude better on both, and living on remote sessions the latency is nice).

I then chose a service level which made economic sense based on my usage (if I get 5 times the bandwidth for 5% more cost then it's probably worth having that, even if I only occasionally use it, and could do the same but slower).

"no one forced them to overbid in the spectrum auctions."

This... The auctions were just that, they could easily have clubbed together and said... Nope - we're not doing that, we'll all invest in a spectrum company, and they can be the only bidder.

Re: "Server error 500"

If you "normally" unlock it with your phone you probably do so over bluetooth, not via the cloud service.

Re: What are error messages for?

Why would that need a cloud server?

VPNs are now utterly trivial (e.g. tailscale) to have in place, allowing you to access your non cloudy light bulbs from any connection.

John Robson Silver badge

Re: What are error messages for?

DALI for lights would be a far better solution, but that does need five cables to each position - so only any good in a complete rewire.

I'm laughing at how many people seem to think that this was the only way into a tesla... there are several options for opening the car, and only one of those (probably the least used) was broken for a while.

Re: Maybe switch to Moon flybys in future

Great visuals, very risky (a very small miscalculation will have unexpected lithobraking), but still a smaller kick than a comparatively safe fly past the larger planet. Of course that safety does depend on people not being complete idiots, and that state is depressingly common amongst decision makers.

John Robson Silver badge

Re: Maybe switch to Moon flybys in future

the moon is much, much lower mass than the earth, so you'd get much less kick - additionally it's harder to target, the orbit of the earth is wobbling about the barycentre of the earth moon system, that point is still inside the earth - the wobble is about six thousand miles. The moon's solar orbit is also wobbling about that same barycentre - but that means that it's wobbling half a million miles.

Re: Let's see what damage is done to diddymoon.

Sample size of two is hardly conclusive (but it's certainly a strong option), and I'm pretty sure that DART itself will suffer badly - even hitting a reasonably sized cloud of dust at >6km/s will do that to... well anything really.

Re: Still surprised

"There are some which are pretty close to that size."

I've just realised that I didn't specify RIE style hearing aids, and the size is rather dependent on the hearing aid type.

But wearing them for 18 hours a day...

John Robson Silver badge

Re: Still surprised

Mine (hearing aids, so costing slightly more than £10) have a BT range of close to 30feet, depends how many walls are in the way - I should test them in open space some time.

John Robson Silver badge

Still surprised

That no manufacturer has looked at the hearing aid form factor.

Several days of battery life, even whilst streaming, and comfortable enough to wear all day long.

I can even replace the batteries in mine, and they have space for a few buttons on the back.

The capabilities of the in ear drivers are astonishing (136dB if you get* the high volume ones) with pretty damned good frequency response, and with open silicone bits you don't get isolated from what is going on around you (closed cups do more isolation, full on moulded in ear sections are pretty isolating).

* Don't get these unless you actually need them, else you'll rapidly need them.

Re: We used to think bigger

That’s just a 12 sky crane fleet… what’s the problem?

John Robson Silver badge

Cost?

Their primary driver was cadence if I recall Peter Beck's comments on the matter. It's not that a reused first stage is hugely cheaper, but there is a significant saving in terms of time taken to build another one, so they can launch more often.

Don't get me wrong, I am sure that that time saving is also a cost saving, but the primary driver was to get more flights in a year, not just reduction in up front cost.

GPU makers increasingly disengage from crypto miners

Re: miners

Except that there is an exchange rate, so there is a "this GPU costs this many bytenotes" or whatever.

The alternative is a gold standard currency, and we abandoned that in the 1930s

NASA delays crewed Moon landing until 2025, citing technical infeasibility

John Robson Silver badge

Re: So NASA will *never* make it to the Moon

Hence the idea to use dragon for landing the meatbags.

The lunar lander (apollo) was first tested on the moon (yeah, slightly disingenuous, the ascent motor was a single use, and therefore each individual engine couldn't be tested).

There is no reason we couldn't have the starship lunar version do an automated landing without people on board (and there is the difference between the 60's and now).

The lack of an independent abort option is the challenge, but NASA have already accepted that, since there are a variety of abort options available - there are six engines on the rocket, and they aren't all needed for a lunar landing.
