It looked like a fault triggered a self-destruction/abort, was a very neat explosion
that bit has been fairly well understood for a while.
Now, rocket engineering on the other hand it's a bit more of a trick!
Still if nothing else, it looked quite pretty when it failed
I saw this article the other day that suggests that whilst there was water on the surface of Mars it was always ice.
Seems plausible to me, unless Mars had a really hot core in the past it was never going to get much energy from the Sun to give it the seas and oceans that are often depicted.
When that game landed on the Amiga the score knocked my socks off, sure I was a big fan of what the C64 had been doing for the most part we just had the blippy tones from the NES, Master System, Mega Drive, PC and whatnot. Then suddenly there was this epic-sounding Korg M1 sampled thing that was being pumped through large speakers in game shops. There really wasn't anything else like it at the time. Sure it wasn't a great game but so what, look at it! And listen to that sound!
OK none of it was as good as Turrican 2 on the same machine but SotB was the reason I wanted an Amiga and spunked all my paper-round money on buying a 500.
However, glad Apple changed their minds. They've always wanted to be seen as the company who is on the side of the creative types. Still don't see the appeal of streaming, devalues music to the level of a cat gif.
When you're in direct sun the temperature can be well over 100 degrees, as soon as you walk into the shade then it's almost absolute zero. Throw in the cosmic radiation on top and your cordless Black & Decker drill is going to have a hard time surviving.
There's a reason probes and satellites cost a few quid, they generally work in these extremes, and when they don't they usually enough redundancy and workarounds to enable them to carry on.
If you're going to go to the expense of building and fuelling a rocket to get your probe into space then you want to be reasonably sure that when it gets there it's going to work.
And destabilises the whole system?!!!
Humans will be accused of destroying other worlds 8)
Does anyone stop to consider how this is done, the materials to be dug out of the ground, a lot of them are rare, to be processed, manufactured, assembled and tested, the logistics of boxing up 4 million phones EVERY day to post them out is mind boggling.
Mr. Musk better start mining asteroids / The Moon quickly the cost of IT is going to go through the roof when all the materials required to make your IC's and screens becomes too rare to be viable.
as in the same layer as fossils of early man, then he'd have 'world-changing' evidence that dinosaurs and humans existed at the same period.
How ever he doesn't, he's desperate to prove his story book is correct and will grasp at anything to do this rather than look at what the evidence shows and let that guide his world view. It's a bit like man-made global warming :P
You have the issue of physical size and life with Lead batteries.
The marketing angle for this is that you could have one at home and mount it on a wall. With Lead it would be at least 3 times the size.
Apple just expect you to run the latest version of of MacOS10, you can run it on quite old machines. The hardware requirements for 10.10 are no different to 10.7
yes it's daft that Apple sell machines that you can't upgrade the RAM on however I can't think of a single one of those that wouldn't have been supplied with enough to run the current version.
If you're running an old computer that's 7 or more years old then you're not really likely to be that arsed about running the latest and greatest software so unlikely to rush out to install the latest revision of the operating system.
Personally I've found that 10.10 hasn't been quite as polished as earlier revisions but the current patch does seem to have brought it back to its old self, of the machines I've tried it on I've found no issues yet.
security fixes = yay
emojils (sp) = WTF are they for anyway?
new photo app = ugh! Apple, I like to list my photos in the order I took them or the order I please, not in alphabetical order only, thanks.
Quite like it so far, not used in anger but it's an obvious improvement over 2011.
It'll leave little Philie on it's own to orbit the Sun, we'll have our first artificial comet then.
One of the big problems is that the likes of Sky seem to have bagged the rights to anything you'd want to watch forcing you to buy into their expensive crappy service.
I quite like the ATV as a device, however the content is very small and what's there is far, far too expensive to consider.
I tried Netflix, liked the idea however almost everything I searched for wasn't there.
I can listen to almost anything I fancy on iTunes or Spotify, it's a shame there isn't an equivalent service to let me watch the same level of content.
Will have to stick to Popcorn-Time for the moment I feel.
Assuming you have a backup, the internet recovery downloads first, this is a tiny program so your tortoise should be OK, you can then rebuild your machine from you backup.
If you're really concerned about such things then keeping an 8GB USB stick with an OSX installer on would save on the download time. But as hard drive disasters are rare having to wait for the OS to download and install isn't going to be that much of a hardship.
As it will increase the prestige of everyone who could only afford a Mini.
You're welcome by the way.
We had a big 13" B&W Hitachi set and in the middle of Dr. Who (Tom Baker), in walks my father with a ginormous 24" colour set from Granada, it was like being at the cinema, you could flip through the 3 channels at a push of a button without having to tune a dial. It would break down almost every month, they eventually swapped it for a 26" model but that had similar reliability problems. We bought a 28" Phillips set that was Nicam Stereo, scarily huge, weighed as much as the moon.
These days I have an old Pioneer 43" 'Kuro' plasma set, it doesn't have all the nonsense features of modern sets but I like the picture, cost a fortune when I bought it but worth very little now. Never been a fan of the huge sets folk seem to buy, they looks a little bit chav wedged into small living rooms.
They've spent all this money on the cable and only reached Cat6a, for £10 I could have bought a Cat7 cable!
In your face Audio Quest!
I remember when a friend of mine got a new ZX81 for Christmas (I would have been about 8 or 9 I think), he had it hooked up to a small portable TV set in his parents kitchen. Simply by switching it on and typing something it was one of the most amazing things I'd ever seen.
or just Apple computers?
How old are they? They must have lived for thousands of years to have been able to observe these changes.
The planet is 4,000,000,000 years old (ish), therefore 4,000,000,000 (ish) of weather and climate.
If the average temp is 0.02 degrees warmer than last year or the other year or whatever then how can you draw any conclusions from it given the miniscule pluck of data?
We've about 80 or so years of temperature records, less for global data, for the most part these weren't very accurate, the conditions where temperatures have been recorded have changed so difficult to really conclude anything.
If we get some hot or cold weather that we've not had in a region for 10, 100, 1000, or 10000 years you still can't really draw any specific conclusions from it given we're talking about 4,000,000,000 years of history.
The correlation between temperatures and Co2 is not that stark and breaks down over the last 15 years. With ice-core samples it showed that Co2 rises follows temperature rises when the oceans warm and degass.
It's been colder, hotter, dryer, wetter, the Co2 has been lower, it's been much, much higher yet the only time bad things seem to have happened was when it was cold (huge storms). For the most part the Earth has been ice-free.
The press are putting out these panic-stricken stories implying that a tiny increase in average temperature over a dataset of only a few years is proof that mankind is fucking things up. But the reality is, whether we're affecting the climate or not the rate of change is tiny and it's always changed. In a hundred years all our fossil-fuel shenanigans will be obsolete and the Co2 we emit will have long dropped and the world will continue doing what it's always done. They're spending an absolute fortune studying a problem that isn't really a problem, there's a million more pressing issues facing humans which are being ignored because of the obsession with the weather.
My telly is about 7 years old (a humble 43" 1080p pioneer set), I have a 'smart' pioneer BD player that lets me stream stuff from my computer as well as watching DVD's, BD's, Netflix etc.
Now I could swap out the TV for a nice pimped 4k screen but I'd still be watching 1080 content.
Sure I could use the real estate on my computer but that's about it.
UHDBD players are still a bit of a myth as is any content, I can't stream it over the Internet (yes technically Netflix and similar are claiming to be offering 4K content but the bitrate is so low it'll have a quality comparable to a 128kb/s MP3)
so the only application I can think of is for anti-aliasing if I have a huwge 60+ in screen and I'm sat with my nose pressed to it.
a bigger difference would be if films improved their frame-rate as they're still stuck in their ancient 24 frames per second.
Or am I missing something?
Nuclear power stations were designed to create weapons grade components for arms, the electricity was simply a byproduct. If you build power stations specifically designed to be as efficient at producing electricity then they're no good if you want to blow people up. They're cheaper to run also.
China is putting big money into developing Thorium based reactors, I think it's clear that we'll see a paradigm shift in our power generation in the not too distant future where the West adopts this technology in order to stay competitive with them.
How would you know?
To produce your own magnetosphere for your craft, has to be lighter than adding in conventional 'shields'.
Would make your ship glow as the solar wind hits it to entertain the crew during their trip to Mars
When it appeared it was unique, the first film to present a distopian view of the future since Fritz Lang's Metropolis from the 1930's!
Visually it's wonderful, sonically legendary, the whole feel and vibe make it totally unique.
The original theatrical cut is a bit lame, but the director's cut is sublime.
The 3001 Final Odyssey series, IMO it's always been a pity that only 2 of the books were made into films.
There's no reason to make another BR film, the original one, despite being the best film ever made lost money, no-one who loves the original wants a follow up, no-one else would be interested. All hollywood has to offer these days is endless sequels, reboots and Marvel films. It's a multi $billion industry devoid of an original idea or story.
A) - That was only relevant to the original studio release after Scott was sacked from the director's chair, the studio added the daft voice over and happy ending. There were no such prototypes in the Director's/Final Cuts of the film.
B) - No as Scott maintained that Deckard was a replicant, hence the whole unicorn scene (and of course 'too bad she won't live, but then again, who does?')
Finally having Ford in it is no assurance of quality, think of the god-awful Indianna Jones 4.
What bothered me mostly about the plot was Blunt had the ability to reset but lost it following a blood transfusion.
How could she know that she'd 'lost' the ability, she didn't know how it worked when she had it, only finding out after the first and subsequent resets, therefore the only way to know she'd lost it would be to die and discover that she was now dead, not much use. Sure she felt 'different' but you would if you'd just come out of hospital following major surgery. Presumably she'd lost the ability and decided not to risk getting killed again when TC conveniently turned up.
TC losing the ability and getting it again for that odd final reset seemed a little crowbarred in, still, enjoyed the film.
His machine will enable you to fly from London to Melbourne in 3 hours, there's a lot of potential there.
It's rubbish that this happened but given it's all new it's unrealistic to have expected there wouldn't be setbacks, however they'll get it right (they're not far off), it'll be certified as flight ready and will change the world.
As soon as my numbers come up I'm buying a ticket.
However, I wish they'd update their TB screen, at £800 they're looking a bit dated and over priced.
Put in countless hours on that game, run the arcade version in my MAME cab.
Another Halloween themed classic on the C64, Cauldron, well worth a punt
to create your own magnetosphere for your craft?
The solar wind is electro-magnetic. If you can power large electromagnets you'd deflect the radiation round the hull of the craft protecting the cargo. You'd be surrounded in aurora borealis every time the wind blew which might be nice but more practical than trying to make a heavy lead-lined spaceship?
Long live the PC (& Mac)!
The current TB screen, whilst awesome it a bit low on the ol' resolution.
This is one reason for the slow take up, yes the download is 1GB but as the installation process encrypts your device it needs 6GB of free space to complete the install and encrypt your device, as a lot of users don't have 6GB free and can't be bothered removing stuff, installing then copying it back they're staying with 7. TBH though as 8 has been a bit buggy I think the take up will be slow until 8.1 appears and resolves these issues.
To an extent but you remove all the pollution from urban areas so the air quality would be significantly improved, also the ambient noise from traffic would be reduced also. There are a lot of gains to be had with electric cars. The downsides are the short range (reduced further when driving in Winter and you don't have an engine to heat the car, so reliant on AC all the time), long refuelling times and maintenance costs particularly for battery replacement.
Still the technology is moving in the right direction and when it starts becoming a viable option for most people we'll see a lot more of them.
Wouldn't it be fairly straight forward to falsely claim that the phones all have uncrackable encryption just to simply silence those concerned about the authorities listening in?
When CD's first appeared they were fairly hideous, plastic sounding things that illustrated the weaknesses of the low resolution, my first CD player had an 8-Bit DAC in it to exaggerate the problem.
Then in the 90's CD players started using bitstream which was basically oversampling or anti-aliasing and their sound quality was transformed. That said the vinyl purists had already made their mind up and and advancing technology wasn't going to change that.
When MP3's appeared they were generally quite low bit-rate, 128k was the norm, maybe 160 if you were lucky. They did all kinds of odd things to the sound, a highly compressed pop track sounded fairly normal but an orchestra sounded like a Casio keyboard. FLAC was preferable as it retained the CD quality. MP3's improved as the bitrate went up, now usually 320k and you can't tell the difference, however the FLAC purists are the new vinyl-types and have already reached their conclusions.
It's a pity that we're still using MP3, MP4 has much better compression enabling decent HD audio with sensible file sizes, there are few devices around these days that don't have sufficient CPU power to play them.
Whilst a trip to Mars would be spectacular it has less to offer that can be monetised.
If Russia, China or whomever start mining the Moon they will be unstoppable.
The ISS is a bit of a lemon, another temporary structure that will be ditched in the ocean soon enough. A permanent facility on the Moon with a focus on extracting raw materials from space could transform energy and manufacturing. Launches from the Moon with its lower gravity to harvest asteroids should be more efficient once the infrastructure has been established. With their 'fuckit, it be reet' attitude to engineering they might be able to pull it off without haemorrhaging anything like the $billions Europe or the US would require to do the same.
Interesting times ahead.
A lot of these attached storage boxes are really loud. Not ideal for a studio.
However if you set iTunes or iDevices to 'automatically download all purchases' then the album would appear locally on your machine and not just in the iCloud to stream from. Where you'd then spend all of 5 seconds removing it just as you'd remove any other track or album you no longer wanted.
Caught his recent tour, he asked the same, most people were happy to oblige.
It made for a better concert as the audience actually engaged with the world rather than just hiding behind a little screen.
Not quite as good as Winter Games or Hypersports but spend a crazy amount of time on games back then.
Hell my cheapo Sony BD player supports DNLA and MKV files, my PS3 also.
Don't MS market their machine as being the only box you need for all your media?
As sexy as they are I can't see it catching on for a while yet, most folk seem happy with DVD never mind BD/1080p. I fear it'll be like SACD, as long as it's good enough few see the benefit of upgrading.
God wouldn't have wiped them out!
The reason most modern music recordings are overly compressed with a very narrow dynamic range has nothing to do with codecs or lossy data compression it's because so much music is portable played on tiny earphones. If you play an old recording on modern iPod earphones it's so quiet you can hardly hear it as all the transient peaks massively limit your headroom. In the old days we'd have big speakers and headphones powered by big amplifiers, if it was too quiet, turn it up! You can't now as the kit doesn't have the headroom to do this so compressing the dynamics enables the whole thing to be played much louder on the small equipment. The reason classical music still has dynamics and isn't overly squashed is because the listeners of that sort of music still tend to play it at home on a larger system.
When I've mastered albums myself for music I've made as I much prefer the old sound and dynamics I've produced the music accordingly and it sounds great on my trusty B&W speakers, however try and convert it to MP3 and play it on an iPod then it doesn't know what to do with it, sounds all wrong and is very quiet. So I use limiters and compressors and all kinds of tweaking to make it as loud as possible, all the subtlety is gone but it works on the go. Active speakers aren't new and using DSP's to correct for room irregularities isn't new either, higher bitrates and better codecs were tried with SACD's and DVD-A's but they failed as most folk just don't care about the quality of sound and they have a very high tolerance for distortion. As long as they can hear the song then it's good enough for them. I think what's also interesting is that when MP3 first appeared it sounded all wrong, the compression sounded alien. Everything sounded electronic and fake. However after nearly 20 years of it we've gotten used to it. If I play a classic CD or LP to my teenage son or his friends who've grown up in this modern audio era the old less compressed & more dynamic audio doesn't sound better to them, it's not the nature of sound quality they've grown up with or heard.
An internal combustion engine keeps the car nice n warm and the ice away. An electric car is going to need a big fat heater to stop them freezing which would kill their range?
I'd like electric cars to work, the local air quality is bound to be miles better if/when they become the norm.
