Yabbut - at least the Pentium got the same wrong answer every time.
I am of a certain age; therefore, you get a like.
when the main aim of a company will not be just the bottom line, but the support of the people whom they employ. The current fashion for zero hour contracts and short-term employment simply isn't stable. A pension fund is a *big* part of an employee's recompense, and changing it at any time should damn well be illegal. *First* the pension fund; *then* the dividends.
Yes, I know a lot of the reasons why a lot of companies were required to take pension fund holidays. Nonetheless, this is not a surprise; longer living pensioners and low interest rates have been predicted/observed for years - so why has nothing been done about it?
Like most of the IoT stuff, it's a solution waiting for a problem. There is a very limited use case where it makes sense, but for the majority of people they *already have* perfectly good mature technology doing most of this.
I can't recall *ever* having had to answer the door when I wasn't in the house... and indeed, I've had *one* break-in in sixty years. The miscreants lifted a paving slab from the street outside, carried it up two flights of external stairs(!), and used it to batter the door down. It's hard to see quite how any of this new technology would have prevented that. As pointed out earlier - a local store of a camera is probably a simpler approach anyway.
Thank you Rudyard Kipling.
Can we stick our heads in the end and say 'boo!' now? Please? I'm bored with always having to hide behind it!
355/113 - let's have some precision around the place!
What's the difference in total kinetic energy delivery between a solid mountain hitting us at orbital speeds, and a mountain full of pebbles hitting us at orbital speeds? The pebbles might not survive to ground level, but they're still going to be dumping all that energy into the atmosphere; there isn't any less of it because the mountain's been blown up.
Seeing it sooner and moving it out of the way seems a more logical course of action.
Because even if you're lost, it's important to be able to pay.
The trick is just to find places where the air is falling up faster than you are falling down. Style is almost always a good thing in these matters.
And versions suggesting also that it was a bet between Hubbard and Heinlein. Stranger in a Strange Land, anyone?
There's an awful lot of conversion up and down and up and down in various flavours of AC, DC, switched DC, stepped DC and the like. Seems a terribly inefficient way to go about things... perhaps it would be nice to have a standardised (e.g) 12v LED lighting circuit, powered directly by a lead acid cell (so 11 to 13.8v really), and maybe a 19v dedicated laptop circuit and a 5v usb circuit? Yes, DC resistance losses, but perhaps less than the conversion losses of going up to mains and back at every stage?
Typing? On a *computer*? How terribly 1990's, darlings!
You sure about the MK14? Mine has metal 'click' contacts (though it's quite likely I have changed them sometime forty years ago).
Not 9cm by 4cm by 1cm, then? Phew,
DC and AC both suffer the same resistive losses, but DC doesn't suffer from capacitive losses n transmission.
I never knew Mytholmroyd was below sea level!
But it does perhaps help to remember Ted Sturgeon's "90% of everything is crap".
They must be hard up...

*Any* of those things are patentable.
Software patents are an idiocy, and the sooner we do away with them the better.
both those links were 'go to and never come back' pages. Not very friendly to hijack the back button...
Please tell me that was intentional.
Either way you get an upvote.
Re germanium: OC71 were about the most common transistors (and you could make opto-transistors from them by scraping the black coating off, until they wised up and started filling the case with a translucent/opaque gunk); OA47 were a very common germanium transistor, very prone to inducing hum from fluorescent lighting if they were e.g. being the detector in a 3-transistor radio and you had the cover off.
And as others have said: the catalogue (along with the Henry's Radio catalogue) was the gem. Even the parametric searching offered by the big three these days doesn't really help if you're just looking for inspiration; there's nothing like flicking through a catalogue on the vague idea that you saw something interesting.
The modern equivalent comes with a 13-page datasheet:
Headley_Grange, you are me and I claim my five pounds.
Though I claim that Maplins was doomed the day I went into the Oxford Road branch for an IC. Turns out it wasn't in stock, but they offered an equivalent on the grounds that it had the same number of legs...
Will these be effective against Putin's new 'unstoppable' weapons?
I wonder if McNamee has ever read a dictionary?
They're all barcoded.
Yes, I have done this joke beefore. Better give me the one with the beekeeper's hat attached, thanks.
This was not only in the immediate vicinity of the LGC aerodrome, it was in the class-D controlled airspace of Luton Airport.
At the time of the incident, from the description in the airprox report, the glider was about to turn for his final approach to the landing field; heading *towards* the ridge and about two hundred feet above the landing field; he would have been at the approximate height of the top of the ridge.
Whether an impact caused damage or not I think i can say with some authority that it occurring at a critical phase of the flight is certainly not something I would want as a pilot; you only get one go at landing a glider.
In most of the country's paragliding sites, it's a question of just turning up and going (with necessary permissions from the site owner/local club). To fly my paraglider at Dunstable, I am required to complete not only a site briefing, but be of a certain experience (or be flying with a coach) and have passed a written exam about the rather complicated airspace. Depending on my ambitions for the day, I may also have to register myself as being in the airspace.
We keep good separation from the kite-flying areas and we have defined exclusion zones to allow the sailplanes to make their final turn and landing approach. The thought of someone up on the ridge flying a drone while I'm in the air terrifies me.
I suspect the fact that you'd have an ephemerides of the available satellites 'simplifies' matters - though I suspect you'd have to use routing software working on the principles of satnav routefinding rather than current gateway protocols.
But yet, if Google is retrospectively removing posts or changing the conditions under which they are shown, how is it that they are still classed as a common carrier and not an editor?
While I'd probably be happy to pay for news sites (the price is still to be negotiated) I'm not at all sure I'm happy to have something that has a billion users increasing the amount of power they use.
Without wishing to start a green war, it does strike me that reducing power usage as a general thing has no obvious downsides and a lot of upsides. Can't see increased usage from coin mining being a *good* thing in and of itself.
Anyone got the numbers on cost of electricity - domestic mains rates are around 12p/kWh I think - vs the value of fake money actually coined?
Since a well-encrypted message is, essentially, as close to random noise as you'd like, and the governments *already* seem to believe that anyone in whose encrypted data they are interested is already guilty, why don't they simply exor the message with the data they would like to be there, and announce that as the key?
The poor 'culprit' has only two choices: admit that the government's chosen message ("It was me wot dun it, guv") is correct, or provide a real decryption.
(Yes, there is a glaring hole in this proposal. It's written in 'the cryptonomicon' cunning concealed in the pocket of that, no not that one, the other coat. --> )
Bear in mind - they hold pressure in the aircraft body at around 8,000 - 10,000 feet - the lower oxygen allegedly stops the self-loading cargo from complaining as much. But it means also that the pressure external to the body is reduced to about 700mb - two thirds of what it's expecting.
Internal pressurisation and bloating and the relief thereof - voluntarily or otherwise - seems a not unexpected result.
That seems harsh. Just hang him upside down at the low tide line for a couple of days...
Seriously - identity theft penalties don't seem to be high enough anywhere. I'm not usually an advocate of long jail sentences, but this kind of thing doesn't seem to be sufficiently punished. Perhaps a recommendation for four years could turn into eight or ten?
That does rather depend *where* it is when it's stationary to earth...
A quick google indicates an averageish orbital velocity for something in the asteroid belt is around 25km/s; the earth moves around 30km/s, so from somewhere we're actually going to have to accelerate the damn things to get them moving inwards. Energy is cheap, but reaction mass might be hard to come by...
I *did* say this wasn't all my idea...
Doug - did you miss my post above?
There is no concept of building balloons on earth and floating them there for any reason; the only reason to make a balloon is to make it easy to move megaton chunks of processed metals around once you've got them here.
And yes, I know they have to come down (speed up, I think?) from an asteroids orbital velocity to Earth's - that's why I'm thinking about aero-braking. There's no sane way of decelerating it chemically, though if you don't care too much about timescale then a solar sail approach might be helpful. I dunno - I build catflaps, not missiles (except on the SPB :)
The idea I think I stole from an SF writer whose name I forget; he parked one over Washington DC to focus the minds of the lawmakers...
I should have explained more clearly: either you live in 'em *in the asteroid belt* or you turn them into balloons and send them back to earth as refined metals.
The first is probably the more useful, in the short term - the second, well, one day I'll get an envelope to do the sums on: you'd need to remove a chunk of energy to slow the bubble relative to the earth, but I suspect ablative braking is probably the only way to go.
But if you can do the dirty smelly energy intensive work somewhere where there's lots of free energy (*big* mirror with the meltee at the focus?) rather than on this green and pleasant land, and do it cheaper, it's probably a good thing to do.
Call me naive, but exactly *which* minerals are so expensive and useful that it's worth dragging them out of one gravity well and into another, rather than digging them up at home?
Maybe it's worth finding iron asteroids, zone purifying them, and injecting air to blow them into a nice big bubble: either live in 'em or let the air out, plug the gap, and send 'em towards earth: get the volume right and they'd float like huge balloons at the altitude of your choice. Refined metals with all the nasty stuff done where the heat and physical pollutants don't affect this rather fragile planet.
Or get out to Saturn's rings and start lobbing chunks of ice at Mars; a few icebergs a day and you'd soon have an atmosphere worth thinking about breathing.
But commercial minerals on the moon that are valuable on Earth, rather than on the moon? Unlikely, I fear.
>> The important part is that they are insisting that they need access - on demand - to any and all communication from anyone, to anyone, at anytime, through any service.
Whereas what I want is that they need access to *one* bit of information every five years, and that without identity: whether there is an X in the box come election time.
Time for a worldwide movement to Mind Your Own Business[tm].
>> when there are buckets of adrenaline in your blood, you're in fear for your life and you've just run to the scene?
Don't see why not - it seems to work all right for Jack Ryan.
Yes, but obviously the NSA had hacked their GPS system to lead them there, right?
Yep, every time.
I have a 23 year old fiat at 180k miles.
I just wrote off a 10 year old fiat (got forced off the road) with 240k miles.
Replaced it with another 10 year old fiat with a 105k on it, put another 7k on it in the last few weeks without issue - including a trip across Europe over xmas the week after I bought it.
But yeah, fiats drop to bits soon as you look at them.
But not it seems most of the commentators here.
I count myself in the 'emails should only contain ascii - not formatted text, not html, and certainly not animations'. But then, I am very old and probably don't understand what the young'ns want from their advertisers, er, correspondents.

What's one of them? Sounds like an 80s arcade game...
The difference between current 'AI' and statistics?

That's the earth's orbital eccentricity changing ever so slightly as Bramah, Yale, Chubb, et all spin quietly in their graves...
