Note that 5 9s is about *unplanned* outage. and to get it you need a design *proecess"

As previous commentards have stated having the nice SAN with the data striped across hot swappable drives and dual PSU's (and even power cables) is useless if you're stuffed by the some cheapo SPOF router which is periodically unplugged by a cleaner to run her vacuum.

I suspect the really tricky part is updating an OS while it's running. Some players understand this quite well (IBM iSeries springs to mind) but I'd guess it's down to sequential shut down, upgrade and re-boot on a per processor basis.

As for end-to-end reliability well that sounds like you should benchmark your system if you really need that level of capability.

Ethernet Vs Ring Practical Vs Theoretical.

Rings have 2 path failures to isolate a node and calculable maximum latency. Handy if you're implementing an aircraft flight control system in a high noise environment.

But IRL most nodes did not want to talk all the time and traffic was quite "bursty" (like the print job to a printer) and the EMI resistance did not need to be important.

Like Betamax Vs VHS?

Re: Limited Expansion

"It's a weird one, especially as they won't cable up new builds. "

As a business decision I find this completely bizarre.

New build is the time to install new services and facilities and (potentially) build market share, provided you can let people retain their old phone numbers (can't all telco's offer this?).

Fibre should remain the state of the art for the foreseeable future. The stuff in the cabinets will change but as long as the fibre can transmit the colours the lasers are using it should last a very long time.

Re: Having an unlisted number

Interesting combination. You should be of no interest except to debt collection agencies.

In which case you should request another new phone #.

John Smith 19 Gold badge

I'm not sure what country you guys are in.

But I've found over the years a few handy things to do and not do.

Have an unlisted telephone number. Or change your current one to an unlisted one. This invalidates peoples existing databases. I'm not on any barring list.

Do not hand out your telephone number to all and sundry on business reply cards, website signups etc. Remember fake phone numbers are more difficult to check from logins on web sites, from the web site PoV, than emails. Mobile numbers seem to be more valuable than land line #s so be especially careful who you release yours to. Dealing with normal scumcompanies I'll deny I even have a mobile to call.

Remember these people are much more desperate to contact you than you are to hear from them.

Pretty much the only spam calls I get are from companies that I already deal with who think I want to extend my "relationship" (IE buy more s**t) with them than I already have.

I don't enter competitions or prize draws. So any BS about "This is an important message" -> hangup.

Ask yourself "If this is an important message from a company you deal with can they contact me another way (IE email, which is fast and does not need a user present to receive it) and if so why have they not done so?"

I go months without getting one of automated spammers and cannot remember the last one I had.

As far as I'm concerned most companies like most governments are

No need to ask. No "need" to know

And yes the biggest source of spam on my mobile is the network operator

Electric cars stall in USA, Australia

A "concept of operations" question.

What's the cycle time to do an automated battery charge Vs a full normal speed charge?

Because that's about how many you'll need on site to keep a replacement station running 24/7. NB It has to be a normal charge because who would want to receive a pack you know has been hammered by the station using fast charge.

If we are looking at an 8 hr charge cycle and a 5 minute replacement that's 96 batteries/station provided you can get the necessary power flow into the site to get them charged (figures pulled from nearest bodily orifice).

And of course at c$5000/pack that would be about a $430k investment for one station.

However once you have a standardized pack size/interface you open up the options. Hybrid modules (packed fuel/engine/generator + battery), flywheels, mixed battery/super capacitor packs for "performance" etc.

So that charge time / replacement time is very important.

It's got a shot. maybe.

A few notes on green energy in Australia

So in some place (where the wind is constant ) wind turbines have reduced outage and improved supply but for others, where sunlight is more constant some kind of solar would be better.

But both need some kind of backup to cover when they are not working (and because power storage is very difficult).

Who'd have thunk it?

As for selling off natural resources instead of processing them in country mining companies mine stuff. They don't really do manufacturing. Besides if you set up local processing in Aus, that might get the locals in other countries becoming uppity and needing a coup to restore "order," which is expensive.

And of course the ultimate expression of that would be nuclear power from locally mined uranium. Potentially a complete energy infrastructure capable of running for centuries. And not forgetting the Austrian bomb (Australia would then be like Japan, capable of becoming a nuclear power, but choosing not to).

I'll note Australia has a huge coastline and could build a lot of tidal/wave capacity out of all proportion to it's own needs for sale to its neighbours (which is how neighbours become good friends :-) )

Usual caveats, highly specialised problem, highly tuned code probably non portable etc.

Today a big address space is 2^64 words and I'm not sure anyone has ever fully populated that for a single processor but 2^57 million is just a whole other ball game.

You'd literally need to store data in terms of individual molecules in a full 3d array to get this kind of capacity.

MP's are handy if you want to do size a hash table and you want to address calculations to be simple. They are a bit sparse (48 of them to get to this number) but a compact table to store, as long as you don't have to evaluate the whole number.

Thumbs up for the effort. Onward to 100 million digits!

A question would be how vague the operators are about stating the exact location of their masts and how much does that affect any derived weather modelling.

Note this would be for weather modelling and nowcasting rather than climate change.

Thumbs up for clever use of data to derive secondary information.

As to why it's never been done before I guess the operators never cared (it's a problem they can't do anything about other than re-site their masts) and the researchers who never asked, probably because they either didn't think the operators kept this sort of data or would not release it to them.

Re: Key assumption:

"That doesn't solve anything. The "filling" station still needs the infrastructure to charge those batteries, and "for a busy station that means hundreds on charge at a time, ready to be swapped.""

Not so. It de-couples the charging from the loading process.

With a big enough pool of each battery type charging goes on 24/7. In extreme cases you can have bulk deliveries of charged batteries.

The key development is in thinking. These batteries are a commodity not a component like the battery in your car. Grades have to meet certain minimum performance criteria (or devices like fuel cells and can expect certain charging rules to be observed.

As for "dangerous chemicals" what would call the 10s of 1000s of litres of gasoline in those tanks?

Re: doomed

"Steam would of course provide a simple enough alternative - fireless steam"

Relative to Hydrogen this is quite sensible.

If you're talking about high strength low weight pressure vessels this is an area that has seen substantial improvements over the years. The maximum use temperature for plastic resins has crept over the years to at least 250c. You're getting toward Pressurized Water Reactor territory. Of course like any good water tank you'll be wanting plenty of lagging to keep the heat in :)

While the technology for large scale steam production and storage is very well understood rolling it out over a sufficient area would be a royal PITA.

It might work out that a straightforward pulsed flow to a crank to drive the wheels would be simpler and more efficient than any sort of clever turbine drive (either through a gearbox or through a generator to electric motors as a hybrid steam/electric).

Superficially madder than mad-Jack-McMad it in fact leverages well understood good state of practice.

It was developed by Ericson to allow them to write the control software for PBX's. It's now out of their hands and independent.

It's focus is on robustness, catching errors before they get compiled and keeping the system up.

I think it's pretty good at being formally verifiable as well.
