Altitude auto pilot
could you just let the thing 'fall'
till it got into an atmosphere that it had a chance of working in,
then turn on the auto pilot.
SR71 was a flop
the SR71 NEVER flew in anger,
Its a fantastic 'plane' , I tremble when I touched the A12 on the carrier in NewYork, its that sort of a plane,
but for the reconnaissance job it was intended, over the USSR ,it never flew.
By the time it got into the air, it was to slow and low.
The U2 , just kept on going,
humans out the loop
the plane is probably better than when it was manned
the plane had to be limited as to what it could do because the human could not survive the G forces,
try holding a minimum radius turn, the pilot becomes a passenger,
the remote pilot is still drinking his coffee and working out how to kill you
it would have taken 10 years to design , so thats technology from almost 50 years ago .
I bet many of the managers get congratulated on this,
but the real engineers, Nahh,
Well done , compare to current designs that have a life measured in 10's of months not 10's of years.
I can imagine the management response," Hay you over engineered it, you should have saved cost / weight",
god bless the guys, with their slide rulers and pen protectors in their shit pocket,
they will all dead now, as they smoked 100 a day, and worked 100 hour weeks,
but I'm envious.
as a student
TDK cassette tapes were THE standard for good quality recording
Good being relative to the time and money,
the "metal" audio tapes were amazing, but just about impossible to erase on early cassette recorders.
this and the 50th anniversary of the cassette , oh how life moves on,
1 is oops. 2 is coincident, three is a trend
So Amazon cloud went do , and back
and Google cloud has gone down, and back
now apple cloud has gone down,,,
three points make a trend,
whats going on !!!!
missed the point ?
I though the point was that this should not have happened, should have been spotted earlier, and should have been reported,
none of which happened,
when it comes to nuclear, are we happy with that situation,
wasnt this amount about the same as the "too expensive" and "waste of money" cost of wiring ( or should that be fibering ? ) the UK with FTTP.
Know what I'd rather spend on,
So thats constructive dismissal then ?
It does have a certain interesting side,
what would you do with a paid 8 hours a day unlimited internet access and time to do what you want.
In google they only have '20 %' creative time,
or is that management spin on things,,
whats it doing now
this reads like the thing is doing nothing whilst we work out what to do with it,
is that really whats happening ?
all that gear just sitting in space, waiting,
please tell me I'm wrong.
why would you NOT have an active roof
Why would one not want to have a PV roof, if its cost effective,
Cost is the measure we use as an economy in the supply demand economy we live in,
As an extreme, if every available and usefull roof and desert were covered in generation plant,
and the world connected up, then sun in one place could be exported to power some where else.
may be PV is not the best option in the dessert, may be the solar towers like in Spain are the way forward, but.
A few pump storage schemes in the mountains of the world, a few convert water to Hydrogen in other places,
its not that hard.
lets leave the gas, oil, coal as a chemical resource we can use, not 'just' oxidise them to carbon dioxide.
what goes around
I seem to remeber,
the original disc drives, all 10 M of them,
plugged into the Apple II bus directly,
what is the surprise
you can make a cannon out of 'duct tape' ,
so why are we surprised that one can make a riffle out of hard plastic.
and its going to take them 12 weeks to turn them off ?
what is that all about,
fantastic flight and pictures.
from 35 Km up,
if you can make the glider glide at 4:1 ,
the glider could cover most the width of the UK,
you could gps it back to any landing place you wanted to ?
have a chat with James May ?
ok at altitude you would not not 4:1
but at lower altitude you should get better than 4:1
so average of 4:1 could be a good average ?
interesting that most / all flights are now days done 99 % by the auto pilot, yet we still have two people in the front to fly.
would we ever allow a fully automatic flight system ?
are we ever going to allow an automatic car to take over ?
I doubt it,
if nothing else, the insurance will still say its the drivers fault, even if they were asleep and car / jet was on auto pilot.
you cant sue a machine,
Re: Virgin media modems also ?
re its Virgins, so they can do what they want,
actually a good point,
I still think of the thing as a modem, with MY router, which it has not been since the 'upgrade' to the superhub.
so now I need a firewall / router that can handle the 100 Mb connection speed,
now thats another problem
Virgin media modems also ?
Been talking with virgin media support,
they have told me what mac and IP address's I have on my network, how long the modem has been connected and lots of other stuff.
wonder what other back doors there are in the "super hub "
how can this NOT be national news
a public body uses computer records to put people in prison
and 'some' records are found to be at fault,
Ok, I can understand a c up happening, but
we need to compensate BIG time all those that it happened to and fast.
Lets get the Quality of the broadcast up to where it can be first,
give the channels more bandwidth to minimize those annoying MPEG effects.
BBC in patticular, the HD channels, when their is a local cutaway,
don't just broadcast a 'please re tune' message.
Either fix it so we get HD local TV ( even if its up sampled )
or put on say the London or something channel,
lets have it such that if there is a HD version of the program available we can automatically jump to it,
( and back when there is no HD version )
put this on a stealth boat,
now that would be a game changer.
Whilst the gas in in the ground,
its an asset.
as technology gets better, it becomes more of an asset, as we can recover more of it for less,
once its gone its gone.
Now what will the politicians decide,
short term or long term ?
I'd look at using of the shelf D type batteries,
by far and away the best amp per Kg density.
try Lithium-Thionyl Chloride type.
or even Streight Ultra Caps ,
ropes do seem a little old hat
Railways were ropes with static engines,
but they moved to engines on the cars a long time ago.
does seem like its time to move to a vertical rail based system,
with all the safety interlocks naturally,
and as said above, it does mean the lift cage does not need to only go up / down, they can switch tracks with points, and can go horizontal as well as vertical,
just needs some one to do it,
wonder if its already patented ?
I KNOW that its 99.999999% probable that the mars rat picture is a fluke,
if it isnt ?
cant curiosity follow its tracks back to have a close look,
Just in case,
if it was something that looked like water, would they follow that up ?
just because its very unlikely does not mean its not true.
the sulphur batteries in one time 'stuff' , ie you dont expect it to come nack,
use a pyro charge to heat them up,
now they are scary when they go wrong,
Netbooks are just right for me.
most of what I need is text based, so by the time yo put a keyboard on a screen of a 'pad' then you are down to a very small screen.
yes, I have a laptop, but its too big and power hungry to do a full flight across the pond,
yes I have a pad, used for games and tv / internet film watching,
yes I have smart phone, lots of apps,
but typing / general most things,
, give us the key board of the netbook,
it does everything in a small package that just works
must admit I'm confused
So what are we to do ?
Insulation is good, or have I got that wrong: take out insulation, purchase more energy, keep more people in work.
Why has most to the Uk gone to flat screen TV's, why are most office computers now flat screens.
why did we switch almost over night to un leaded petrol,
why is it that cars now can do 50 mpg, where as only a few generations ago they could only do 20 mpg.
is it that most to the things I mention above are on a short turn over, 10 years or so,
whilst buildings are 10 times that slower at turn over.
energy wise it would be great to knock all the existing buildings in the uk down, and build much better insulated ones, it would even solve the job mountain,
what are we to do, can we go digging out old carbon deposits and burning it at the rate, or higher than we already are.
Nuc, why not
Strikes me that its not the Nuc thing thats the worry, its the shocking in competence of the operators and managers that's the killer.
did any one else see the bbc 2 Challenger program the other night ?
could be re titled, Nasa ups and downs Apollo 1 to Challenger.
it is sad, to me anyway,
that I already have MS documents that are no longer even readable in MS programs.
its back to paper records me thinks,
Now were the US putting up a mil shuttle as well,
he will be missed ,
I once as a kid in the 60's was at the London planetarium,
he gave a special presentation to the school kids.
he had us all wanting to be scientists.
BTW: re " Young Moore was present in NASA ground control for the Apollo landing"
was he not in the BBC studios in the UK ? I seem to remember him crying at the landing. bu tit wa sa long time ago..
the world is a better place because of him.
Interesting Questio for the pub...
If I have an item printed in say the netherlands, and ship it to say the usa,
is the import duty that of a print , or that of the thing I have had printed ?
a few Km of ehtenet cable, thats the 50 ohm coax stuff, and quite a few BNC connectors / T pieces.
A pile of ISA and such boards.
A stack of old memory, some in DIL packages....
Leads of all types. in a pile so big that I don't know what there is, so just get another one from the stores.
if I want a twisted pair ethernet I can only find USB. If I want usb, I can only find Firewire, and don't get me started on the pile oif 'usefull' D connectors in various forms and configuration, null modem, loop back, loop back with control, cross over, etc etc. all carefully labeled up, with sticky labels that are now falling off into the boxs.
then we old mother boards, PSU's of various vintages,
cases that only accept BTX boards,
but why would I want any of it
a raspery pi is more powerfull than any machine I could make out of this lot,
but I can' t chuck it, they might be useful, one day,
so on third house move they go again from one attic to the next, box's un oppened.
I think I need a coffee now, and may be a trip down the local computer flee market at lunch time to see what else there is I NEED.
this hub does have the worst reputation , and massive set of problems.
its amazing the company that makes the hardware and the firmware has not pulled out, they must be getting a terrible reputation.
personally, I had lots of hassle with it,
I ended up reseting it each night, and that seems to help,
but do I feel happy having to cross fingers to have a hub, NOPE.
yes, I'd be happier with a small , low power modem only, not this dammed great big power guzzler / heater.
and no, modem mode is no answer, the hardware is still there,,
so some one looks at the background,
and decides what colour to squirt into the baloon !
now the micro channels done by 3d printing is interesting,
super hub , too much in one box ?
I purchase an adsl router, and I might get one or two updates,
After a few years, it might be missing the latest features features, but it works reliable
The super hub,
which 'upgrade' are we on now ?
hay the last one even changed the gui on the log in page,
talk about deck chairs on the titanic.
now if they could split the function in two,
the basic cable modem part, and the add on parts,
I guess thats what the modem mode does, but that turns off the second part.
it still chews up power etc,
I do not know, and its a question,
hand warmers I think work on a reaction between iron and oxygen.
at altitude, I'd imagine there is not sufficient oxygen to actual make them heat,
are they 'just' working by thermal mass ?
If so, would thicker insulation,
and a hotter lump at the start be more efficient ?
sort of thinking heat a LUMP inside the unit up to a HIGH temprture on the ground,
? mains power ?
then unplug and launch. no need for access flap to chuck in hand warmers,
so could make better insulation ?
i wonder ,
what is the volume of ice that has dropped off each 'month' .
is thee as trend forming,
it has puzzled me,
technicaly, we can build large pressure containers to hold nuclear reactors,
is not under water pressure vessel 'just' a big version of the same ?
the small vessles we currently have for sub sea are limited , by the fact they have to fit on a ship, or are to be stealthy.
If you can build BIG, with lots of concrete, how hard can it be to build a container that can sit at any depth ?
its not like you have to fly it into space, it can float .
Look at the size of the big oil rigs, instead of building tall, make stong,
hats off to the engineers
an amazing bit of what we used to be able to do stuff.
how many computers of today will work in 40 years time ?
with my managers hat on, these are failures,
they were obviously over engineered, lasting much longer than they are intended to
cost way more than they could have , and stopping us selling new / better toys
or have I that wrong some where ?
How we used to be able to make stuff that did a great engineering job,
Just a thought
An Arduino must have about the same 'power' as a psion II or even a 3 ,
they can run for a few days on a PP3.
just charge the world in US dollars the same price ?
or is that too easy ?
is it only me BUT,
self duplicating stuff that can combine with other dna,
now that sounds like a bio containment disaster waiting to happen
